Digestive System Diseases and Disorders
The digestive system is made up of the "digestive tract" -- which is, according to the National Institutes of Health, a "series of hollow organs joined in a long, twisting tube from the mouth to the anus" -- and additional organs that are part of the system that helps humans "break down and absorb food" (National Institutes of Health -- NIH, 2009). If something goes wrong in the digestive system it can have serious consequences for the individual. This paper identifies some of the disorders that are associated with the digestive system. The organs that are part of the digestive system include the mouth, the esophagus, the stomach, the small and large intestines (the large intestine is also called the "colon"), the rectum and the anus (NIH, p. 1).
The digestive system is one of the most important parts of the human body because food…

The gastrointestinal system extends from the mouth to the anus. It includes the oral cavity, esophagus, stomach, duodenum, small and large intestine, rectum and the anus. The digestive system also includes other organs responsible for digestion, namely the liver, gall bladder and the pancreas. By way of the peristaltic movements of the tract and enzymes secreted from these organs, food is digested and absorbed; to be either stored in the body, or used as energy. Nerves and blood vessels also play a major role in the digestive system. (Kumar, 2007)
Diseases of the digestive system are a major cause of morbidity and mortality worldwide. Approximately ten percent of all general practitioner consultations in the United Kingdom are due to digestive problems, with a majority resulting from diarrhea. In the United States, approximately $85.5 billion are spent on GI and liver diseases. (Boon, 2006) The highest cost per year…

It is also at this point that other organs begin to play a major role in the digestive process. The pancreas, located adjacent to the small intestine, secretes several enzymes that variously break down carbohydrates much further than they were broken down in the mouth or the proteins that began to met their demise in the stomach (NDDIC 2008). The liver produces a bile that breaks down fats and makes the constituent parts into small enough droplets that they can be suspended in water and utilized in chemical processes in the body (NGS 2010). All of this digestion takes place in the duodenum.
The small intestine continues, however, and throughout the entire small intestine are countless villi, or little finger-like hills that greatly increase the inner surface area of the smooth-muscled tube that is the small intestine (Discovery 2000). It is through the cells of these villi that the nutrients,…

The blood and lymph systems are also vital to digestion's efficacy, transporting nutrients to the cells of the body where they are needed (Smith & Morton 2001). Again, most of the "action" of the accessory organs and their products takes place in the small intestine where the major work of both breaking down and absorbing nutrients takes place (SUNY 2010). It is here that the enzymes secreted by the pancreas and liver arrive to do their work, and it is through the small intestine -- and primarily through the duodenum -- that carbohydrates, proteins, and lipids (fats) as well as other vitamins and mineral nutrients reach the lymph and circulatory systems that carry them throughout the body where they are useful (MNSU 2010).
Pancreatic amylase, one of the enzymes secreted by the pancreas, continues the breakdown of starches that begins in the mouth, converting these carbohydrates into maltose (SUNY 2010).…

nervous and digestive systems at reptiles, emphasizing their main characteristics and briefly compare them to the nervous and digestive systems at other vertebrates.
In this sense, referring to the reptilian nervous systems, many authors have found common basis and similarities between the nervous systems of reptiles and other higher vertebrates, including mammals
These similarities manifest themselves both in the form of anatomical and physiological resemblances. The main difference between the reptilian brain and that of higher vertebrates such as mammals relates to "the size of the cerebral hemispheres"
As such, the reptilian nervous system is formed of two different components: the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system is composed of the brain and the spinal cord, while the peripheral nervous system is composed of all nervous tissues and structures that do not actually belong to the CNS.
As at other vertebrates, the…

Human digestive system is composed of multiple parts, including the mouth (pharynx, throat, palate, tongue, teeth), stomach, small intestine, large intestine, liver, pancreas, salivary glands, bowels, and many more. The sole purpose of the digestive system is to break down foods that are eaten, so that the food might be absorbed into the bloodstream. The existence of a digestive system sets animals apart from plants. Digestion consists of a physical and chemical breakdown of food. Because of the complexity and large size of the digestive system, diseases that can interfere this body system are numerous and varied in their modes of transmission, their symptoms, their treatments, and their possible short-term and long-term effects. This paper will focus on three such diseases: Cirrhosis of the liver (caused by viral Hepatitis), hookworm disease (caused by hookworms), and cholera (caused by Vibrio cholerae).

Digestive Disorders: Inflammatory Bowel Disease and Irritable Bowel Syndrome
It is important to note that in some instances, the symptoms patient present could be tied to a myriad of disorders. This has in some quarters led to misdiagnoses. Both inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS) present a number of similar symptoms. IBD includes a number of inflammatory conditions whereby sections of a person’s digestive system are attacked by his or her immune system. The said conditions are inclusive of ulcerative colitis and Crohn’s disease. IBS, on the other hand, “is a problem that affects the large intestine” (U.S. National Library of Medicine, 2018). In essence, the movement of food in the intestines is enhanced by the relaxation and contraction of the intestines. When the said contraction as well as relaxation does not follow the normal pattern, symptoms of IBS are likely to present.
In basic terms, the…
Lipids and Proteins
Lipids are fats and they are important to our health. When chemically digesting these lipids or fats, these molecules are broken down into smaller ones that can be more readily passed through the digestive system and into the bloodstream. This fat is transformed into triglycerides and can be used by the body for energy at a later time.
Lipids like almost all food is first mechanically digested by the mouth. During this process the first chemical reaction begins when the saliva begins to break down the fat. As the fat is digested, enzymes called lipases within the mouth and stomach break the bonds of the lipid molecules an prepare them for absorption. The gall bladder and pancreas becomes involved in this process as bile salts are released from these organs and secreted in the small intestine. These chemicals signal to further digest the food by breaking…
Digestive Disorder: Diverticulitis
The patient is a 37-year-old female with a family history of colorectal cancer mandating regular colonoscopies before the age of 40. The patient's diverticulosis was discovered during a routine colonoscopy at age 35. She was asymptomatic for 2 years, but developed diverticulitis at age 37. When she began experiencing significant pain her lower left abdominal area, she suspected diverticulitis, called her gastroenterologist who referred her to the emergency room for a cat scan, which confirmed the diagnosis, and then given a course of antibiotics, which resolved the issue.
"Diverticulitis develops when feces become trapped in pouches (diverticula) that have formed along the wall of the large intestine. This allows bacteria to grow and cause an infection or inflammation and pressure that may lead to a small perforation or tear in the wall of the intestine. Peritonitis, an infection of the lining of the abdominal…

e. hypertrophy). In the elderly, this process is reverse. Hence, the functional reserve capacities of the skeletal muscles decline with age, largely due to diminished levels of physical activity. As a result daily tasks once taken for granted become progressively more difficult, and eventually impossible, to perform. In illustration, a great deal of muscle force is required to simply stand up or to climb stairs. Therefore, skeletal system is relying upon the reserve capacity of the heart to provide the endurance needed to perform such activities. If an elderly person does not engage in some sort of endurance-based activities, he or she will not have the cardiac reserve capacity needed for daily tasks. More importantly, diminished capacity may not counteract illnesses or diseases. Although strength-based activities help the cardiac reserve, it may not benefit the skeletal system.

Integration of Cardiovascular/Gastrointestinal Systems
Integration of gastrointestinal and cardiovascular systems within the human body
The integration of the gastrointestinal and cardiovascular systems allow for nutrients to be introduced, broken down, and absorbed by body to maintain and promote healthy bodily functions. Independently, these systems serve separate functions, but when working in conjunction, help to transport necessary nutrients throughout the body, while maintaining and promoting homeostasis within the systems. Any imbalance within these systems will greatly affect the body, as a whole, and can lead to potentially fatal results.
Integration of gastrointestinal and cardiovascular systems within the human body
The gastrointestinal and cardiovascular systems of the human body help to breakdown and transport items that are ingested, such as food and medication, to the necessary parts of the body, expelling wastes that are not needed.

An organization can achieve a competitive edge only and only with the help of its employees. Therefore, it is necessary that right employees are selected then trained and developed and a performance-based reward system. The question then comes to the performance measurement system. In a furniture retail store where I work they stick to the old practice of a meeting of top managers and supervisor who sit down annually and critically review the performance of all customer service personnel. They carry out a thorough examination of employee performance with respect to the goal set for them by the management. In this setting where only goals are there to guide employees and performance appraisal system is vague and subjective, most employees are just interested in meeting their targets and they do not strive to exceed their employers expectations.

The circulatory or cardiovascular system is responsible for moving nutrients, wastes and gases between body cells, transporting blood across the whole body and battling disease (Circulatory System). Its principal elements are the heart, numerous blood vessels, and blood.
The heart forms the circulatory system's core. This 2-sided, 4-chambered pump which distributes blood to various arteries comprises of the right and left ventricles, and right and left atria. The ventricles, situated within the heart's lower half, are responsible for pumping blood to the whole body (away from our heart), whilst the atria, situated within the heart's upper half are in charge of receiving blood from different parts of the human body. The right and left ventricles pump de-oxygenated and oxygenated blood, respectively; de-oxygenated blood is pumped to lungs while oxygenated blood is pumped to the remainder of the human body (smith, 2013). These 4 chambers are connected to one another by…
Lymphatic system is a sub-system of the circulatory system. It contains a network of nodes, or vessels and filters, which remove toxins from the body. The role of the lymphatic system in the homeostasis of the body is that it serves as the primary drainage for all of the body's other systems, removing all toxins and excess fluids. It is a major defense against disease and also helps carry nutrients throughout the body.
The lymphatic system does not circulate blood. Lymph is its primary fluid and is formed from fluids surround cells throughout the body and passed into lymph vessels. If this fluid were not removed or filtered, the result would be toxins accumulating in the body. This would create swelling and also prevent the body from fighting against infection and disease.
Disorders or complications originated in the lymphatic system create serious illness in the body. This is because this…

Digestive System Disorder Case Study: Gastroparesis
The paper opens with an introduction and definintion of Gastroparesis and its association to damaging of vagus nerves along the intestines and stomach muscles. This reduces their ability for function properly. People living with diabetes have a higher likelihood of advancing Gastroparesis against sequential Diabetic Gastroparesis. More persons are contracting Gastroparesis during surgical operations. The paper illustrates that more patients are yet to find a cause linking their illnesses with Gastroparesis because it triggers Idiopathic Gastroparesis. The scope of Gastroparesis has a close link to diseases of connective tissue such as Ehlers-Danlos syndrome as well as scleroderma. The neurological conditions worsen along Parkinson's disease. The paper concludes with proposals of Gastroparesis diagnosis through tests carried out on gastric emptying scans, x-rays, and manometry. Clinical Gastroparesis takes the definition of stomach emptying complications. There are beneficial adjustments to insulin dosage among diabetic people who…

Planning and Reflection
During my student teaching experiences I kept a journal, which greatly helped me to organize my thoughts and clarify the areas in which I most needed to improve. My mentor also pointed out for me the key areas that need improvement. Therefore, as I look forward to a professional career as a teacher, I will be able to draw on these early experiences. I will remember what works and what doesn't and I already feel far more confident and proficient than I did before I undertook the student teaching challenge. In general a few major themes emerged through reviewing my journal entries and the statements written by my mentors. My strengths are my willingness to use a wide variety of teaching materials and teaching styles. An enthusiastic implementation of multimedia materials keeps students actively engaged, and keeps lessons more interesting. Moreover, my lessons are well-planned and incorporate…

Gastroesophageal eflux Disease (GED)
Gastroesophageal reflux disease (GED) can be caused by a number of different medical conditions. People suffering from obesity are more likely to develop GED, and given the obesity epidemic in the United States and other western countries this explains why the prevalence of GED approaches 20% in these countries. Pregnant women, smokers, diabetics, asthmatics, and anyone who suffers from slow digesting also have an increased risk of developing this disease.
Some people may suffer from genetic or medical conditions that predispose them to developing GED. A hiatal hernia results when the upper portion of the stomach pushes up into the tube that connects the mouth to the stomach, the esophagus, and if the hernia is severe enough then GED may develop. Schleroderma is a rare, progressive disease that causes the skin and other connective tissues to harden, which may interfere with the proper functioning of…

The blood in which we are traveling in is composed of red blood cells called hemoglobin, plasma, platelets, and white blood cells. Blood is transported through the body by the heart's pumping action. As we continue, we will enter the hepatic portal vein, which delivers blood from the gastrointestinal tract to the liver, into the ascending aorta, up towards the heart. As we approach the heart, it's pumping will pull us up into its chambers and through to the lungs where we will get oxygen and continue our journey to the kidneys. As we return to the heart, we will pass through the aortic arch and descend through the thoracic aorta continuing past the descending abdominal aorta until we reach the renal artery. We will make a left turn and pass through the glomeruli through the kidney's tubules and conclude this phase of our journey into the left kidney.

The success was remarkable, according to the researchers: Even muscles that had already lost half of its mass, recovered visible. (Leppanen et al. p5549-65) At the same time, the mice survived for several weeks longer than their untreated counterparts and also developed a healthy appetite again. (Mantovani, p296) The new study is therefore interesting in two respects: First, it demonstrates that the muscle loss at least in animal models in fact, affects the chances of survival, and secondly, it shows a way, may be how to prevent this degradation, and even reversed.

Muscle atrophy is a medical term that refers to the decrease in the size of skeletal muscle, losing muscle strength because of the strength of muscle is related to its mass. (Burnfoot, p323-34)

Describe the major metabolic diseases associated with lipid metabolism, transport and storage for humans?
Diseases associated with lipid metabolism, transport and storage included: high cholesterol, combined hyperlipidemia, familial hypercholesterolemia, high density lipoprotein, and hypertriglyceridemia,
How do unsaturated and saturated fatty acids differ from each other?
Saturated fats contain carbon atoms with a single bond between them and as many hydrogen atoms as possible bonded to the carbon atoms. Saturated fats contain carbon atoms with a double bond, and can therefore absorb more hydrogen atoms. Healthy diets are low in saturated fats, since they raise blood cholesterol levels.

They are worm like animals that have muscular body walls that elongate. They are also circular in cross section. The major difference between Phylum Annelida and other worm like creatures is that, they have segmented bodies (also known as metameric). Each segment has its own particular function. Phylum Annelida include different types of earthworms, leeches and marine polychaetes. There are those that live in fresh water, marine also terrestrial. Some of them live as parasites.

S. Congress that the prospects of stem cell research were so vast that it could touch all the realm of medicine (Connor 2000). An unlimited source of embryonic stem cells will solve the problem of shortage of transplants. Embryonic stem cells will save lives by curing generative diseases of the brain, hepatitis, diabetes, leukemia, rheumatoid arthritis, muscular dystrophy and cystic fibrosis and diseases of the heart and kidneys. ut current laws restrict the use of stems cells on embryos less than 14 days old and for correcting fertility, reproduction or congenital disorders. The restriction is grounded in the belief that the embryo is a potential human being from the moment of conception. It thus possesses a soul and a dignity just like any other viable person (Connor). Previous scientific research presented evidence that genetically engineering cells could partly repair a defective immune system (Travis 2002). Two new studies bolstered this…

Based on etiologic differences, male-to-female ratio is 1.5-3:1. Primary biliary cirrhosis accounting for only 1.5% of deaths from cirrhosis is mostly found in females and ethanol-related cirrhosis is greatly found in males. Age-specific death rates in the United States tend to be greatest in the older age groups, topping at 49 per 100,000 males aged from 65-74 years and at 26.7 per 100,000 women of the age group from 75-84 years.

Alcohol is classified as a depressant because it slows down the release of neurochemicals that inhibit certain behaviors. The subjective feelings associated with alcohol intoxication are due to its effects on the brain and central nervous system but that system also controls our behaviors. The depression of certain neurotransmitters often reduces reflex time and reduces general inhibitions.
The digestive system is also strongly affected by alcohol consumption. Alcohol is absorbed almost entirely by the small intestine, from where the alcohol seeps into the blood. The liver is strongly affected by the absorption of alcohol and is in fact the main organ responsible for metabolizing alcohol. hen too much alcohol is consumed, the liver becomes overtaxed and cannot filter the toxins from the body as fast as it normally can. Over the long-term, the liver can become permanently damaged from too much alcohol consumption.

Non-Cardiac Chest Pain
Background- Chest pain is one of the most common reasons people call for or visit the Emergency Room for help. Heart attack education has brought to light the urgency of seeking immediate medical treatment if one suspects they are having heart issues. However, chest pain does not always signal a heart attack, and may be totally unrelated to issues with the cardiovascular system. Often no clear reason for such pain presents itself during examination, but understanding the perception and pain experience can help medical professionals understand different experiences that lead to patient panic about chest pain (Jerlock, Gaston-Johansson, & Danielson, 2005). Typically, if chest pain is related to a cardiac issue it is usually associated with one of the following symptoms: 1) pressure, fullness or extreme tightness in the chest; 2) crushing or searing pain that radiates to the back, upward through the jaw, and especially through…

scientific effects of smoking on the human body especially on the respiratory and cardiovascular systems. We will give a brief analysis on how smoking affects the mentioned systems and see how the human body system works if the individual does not smoke. We will also support our paper with scientific and statistical evidence regarding the facts related to smoking.
Smoking and its effects
Before looking at smoking and its effects lets review on how the respiratory and cardiovascular systems work. When we breathe air it first enters Trachea/windpipe through which it enters on each of the bronchi present at both of the lungs. The bronchus is spread throughout the lungs like branches on trees and at its tips is as thin as a hair (bronchioles). Each lung has about thirty thousand bronchioles. At the tip of every bronchiole lies an area which leads to tiny air sacs known as alveoli.…

It is a well acknowledged truth that memory related diseases like Alzheimer's are common in older people rather than younger ones. Memory tends to becomes less competent with age. It might take longer to learn new things or remember familiar words or names. Many measures can be adopted to reduce the increasing adverse effects of memory like eating a healthy diet, including physical exercise as a part of daily routine and by being social. Despite of adopting these measures to reduce the effects of growing age on health, these problems cannot be eradicated completely. Young people are more energetic and are less viable to diseases because of the strength of their immune system. They have a stronger defense system against diseases because of the age. There is a strong relationship between age and support of health. Aging is inevitable. It is tend to occur but applying few important measures cannot…

Modality and Public Health
Naturopathic medicine is a system for primary healthcare described as a science, an art, philosophy and the practice of diagnosing, treating and preventing illnesses. This is usually practiced by registered or licensed naturopathic physicians (Meadows, 2013). Naturopathic medicine is a tradition which is science-based which promotes the wellness of patients through the identification of unique aspects of every patient and then employs natural therapies that are non-toxic in order to restore their psychological, physiological as well as structural balance. Naturopathic medicine is not usually defined by the type of substances that are used rather it is defined by principles which underlie and therefore determine its practice (The Healing Arts Center, 2010). These principles include; the healing power that exists in nature, finding the cause of illnesses, causing no harm to patients, treating the whole person, prevention of illnesses and doctors acting as teachers to patients.

Digestion and diabetes: Overview of the process
The digestive process begins even before food is consumed. Looking at or anticipating food causes salivation. Saliva aids digestion, along with chewing. For example, when Jane Doe looks at a plate consisting of a whole wheat turkey sandwich (garnished by vegetables and mayonnaise), potato chips, and apple juice, her body will begin to anticipate eating by secreting digestive juices. The first major involuntary muscular movement for Jane Doe will not occur until she consciously decides to swallow the food in front of her. "Although you are able to start swallowing by choice, once the swallow begins, it becomes involuntary and proceeds under the control of the nerves" (Your digestive system, 2010, NIH). The swallowed food is pushed into the esophagus, the organ that connects the teeth, mouth, and tongue through the throat to the stomach. "At the junction of the esophagus and…

What is Cnidaria? What is it made up of? Who are the members that belong to his group? Cnidaria is an exclusively aquatic phylum. It is a group that is represented by the members, who are also called 'polyps', and these are sea anemones and corals, and also by 'medusae', which are creatures like the jellyfish. In general, both a polypoid as well as a medusoid cnidarian will be either radially or biradially symmetrical and it is an uncephalized animal with one single body opening, which is the mouth. Stinging capsules, which are embedded in the tentacles that are placed around the mouth, generally surrounds the mouth. These stinging capsules are also known as 'nematocysts', and these are capable of acting both as agents of defense as well as of offense. The most important distinguishing feature of a phylum is the presence of the intrinsic nematocysts, and in turn,…

These biologically-based practices of alternative medicine include the use of vitamins, herbs, and food supplements found in nature, chief among which are probiotics: the living, beneficial bacteria found in the intestines. These benign bacteria counteract the presences of the malignant variety, which often cause digestive problems if allowed to overpopulate. Probiotics can be obtained as supplements or found in certain foods, and have been known to prolong periods of remission in ulcerative colitis patients, with no sever side effects.
The use of fish oils is another alternative medicinal treatment for ulcerative colitis. Fish oils contain omega-3 fatty acids, which are known for their anti-inflammatory properties (Crohn's & Colitis Foundation of America, 2011). Omega 3 fatty acids are found in certain green vegetables and in nuts, salmon, sardines and herring, as well as in oral supplemental form and are used to treat intestinal inflammation when ulcerative colitis is active.

Some studies posit that casein consumption has a direct correlation to cancer cell growth, and patients with any form of cancer are counseled not to drink milk, and to limit the consumption of milk products. This is contradicted in terms of using milk to help with certain stomach and colon cancers (Hakkak, 2001). Men who drink large amounts of milk and consume numerous dairy products are at a higher risk for Parkinson's disease, and high levels of calcium intake (6 or more glasses of milk per day), also increase the chance for prostate cancer (Chen, 2007; Giovannucci, et.al. 1998). Additionally, a number of links have been made to digestive disorders such Crohn;'s disease and Hirschprung's disease, which are serious conditions of the digestive system and the bowel ("How Bacteria in Cow's Milk…" 2007).

Animal Nutrition and Feed Evaluation
Qualitative, scientific-based evaluations of animal feed and the resultant nutrition of the animal are crucial for maintaining optimal animal health and responding to problems that develop as a result of diet. In the case of ruminants, this can be particularly important as their unique digestive system can complicate providing optimal nutrition from traditional feed sources and techniques. A balanced nutrient approach to ruminant diet must take into account not only the feed that is being given to the animal, but also, crucially, the way in which the animal's digestive system will process that feed and provide (or not) nutrition to the animal. Creating this type of qualitative knowledge about the digestive system and nutrition needs of rumens with regard to different feeds "developed most rapidly when isotope dilution techniques became easy to apply, facilitated by improved instrumentation and mathematical approaches" (1). From this information,…

Spina Bifida is one of the many birth defects neonates are at risk of. However, this particular defect is unique because it is characterized by problems in the central nervous system (CNS) and it has a low death rate. The causes of this medical condition are quite difficult to determine as they are subject to hereditary and environmental elements. Simply put, Spina Bifida refers to a situation where the spinal cord is not fully developed. In extreme cases, the spinal vertebrae could be so badly formed that the delicate spinal cord is left unprotected. In most cases, the spinal cord suffers damage due to this. The baby could suffer from reduced brain function and poor transmission of commands to affected organs. This slightly damaged link from the brain to the body tissues and organs leads to poorly developed body systems. There are other associated problems with this spinal defect even…
Liegl-tzwanger, Fletcher and Fletcher (2010) pointed out that the exact incidences of gastrointestinal stromal tumors in the United States and Europe is not easy to determine. This is attributed to the fact that GISTs got proper recognition as well as diagnosis from the late 1990s.Studies carried out in Iceland ( Tryggvason et al.,2005), Sweden (Nilsson et al.,2005), as well as Holland (Goettsch,2004) have indicated that close to 11,14.5 and 12.7 cases per million people per year respectively.Incidences if GISTs have been shown to be higher as a result of the fact that most patients live with it for several years and it gets detected only during gastrectomy or autopsy all of which are usually performed for other reasond. study by gaimy et al.,(2007) which was performed consecutively on autopsies indicated that small GISTs having between 1-10 mm in about 22.5% of the individuals aged above 50 years.These small GISTs…
About 50% of the GISTs exhibit a loss of gene off the arm of chromosome 22. This discovery is associated with the progression of the malignant GIST (Fukasawa et al.,2000;Bergmann et al.,1998;Kim et al., 2000;Lasota et al.,2007). There are however some losses that are less frequent on the chromosomes 9q,17q,1p and 11p.Gains are however noted on chromosomes 17q and 8q all of which have a strong association with malignant behavior (El-Rifai et al.,2000;Schurr et al.,2006).
Extant literature has been dedicated to the study of the clinical features of GISTs.GISTs are mentioned by Liegl-Atzwanger, Fletcher and Fletcher (2010) to occur in almost every part of the GI tract.They are however more common in the stomach regions ( about 60%), ileum and jejunum (close to 30%), colorectum (about 4%) and duodenum (about 5%).GISTs are rarely seen in the appendix and esophagus (Miettinen et al.,2006;Miettinen, Sobin and Lasota,2005;DeMatteo eat al.,2000). Tumors that lack any form of association with the wall of the bowel are given special name- extragastrointestinal stromal sarcomas are noted to occur in the mesentery, omentum and retroperitoneum (Miettinen et al.,1999;Reith et al.,2000). The clinical symptoms that are associated with GIST are abdominal pain, dysphagia, obstruction, fatigue and satiety.It has been noted that patients may be presented with chronic bleeding to from their GI (Causes anemia). The patient may also present acute bleeding to GI ( as a consequence of the erosion via the gastric or the bowel mucosa). There could also be a rupture into the patient's abdominal cavity thus causing a life-threatening condition called intraperitoneal hemorrhage. Nilsson et al. (2005) indicated that a population-based research indicated that close to seventy percent of GISTs were related to clinical symptoms while twenty percent were not. 10% were detected at the time of autopsies.

lactose intolerance, and a description of its' relevance to nutrition; consumers, health care professionals, and patients. Lactose intolerance is a disease aggravated by milk sugars. It can be controlled by diet, but often other measures must also be used to control the disease, such as the use of dietary aids such as "Lactaid." Health care professionals must understand the treatment and problems associated with the disease to help their patients combat the disease, and a major portion of understanding lies in the principles and understanding of proper nutrition.
Lactose intolerance affects millions of Americans. In fact, the American Gastroenterological Association (AGA) estimates that 50 million Americans suffer from the disease, and it can make their lives miserable if it is not treated. The symptoms of lactose intolerance include stomach cramps, diarrhea, nausea, gas, painful bloating, and flatulence ("Living" 66). These symptoms can begin as soon as 30 minutes after consuming…

Earthworms are hermaphrodites since they can generate both sperm and eggs. Mating involves 2 earthworms inseminating each other where sperms are exchanged. The male and female sexual cavities are located near the clitellum. They connect the lower ends of their anteriors with heads positioned in reverse directions. Mucous secreted joins the openings with slime. Sperm is pushed into the longitudinal channels formed by the mucous. They reach the sperm receptacles of their partner, which then break apart. Laying of the eggs and fertilization follows ("Native Australian," 2006)
The circulatory system is constituted of the heart, blood and blood vessels. It is needed to distribute nutrition to different areas in the body and is of two types -- open and closed.

As will be demonstrated in the Literature eview, specific Constitutional language from Article I give Congress and only Congress the express authority to make laws and regulations pertaining to the armed forces.

These worms play an integral part of the community. They do not have any digestive capacities, as they lack mouths and digestive systems. ather, they absorb the nutrient-rich waste products of the bacteria through their epidermal layers. They use hemoglobin produced inside their bodies to combine hydrogen sulfide, which is a necessity of many of the bacteria living in and around the vents. The worms transfer this hydrogen sulfide to the bacteria upon contact, and in return, the absorb the nutrients being produced by the bacteria. Additionally, one study examining vents off the coast of South Africa also found the presence of a new species of nematode, known as Halicephalobus mephisto (Borgonie et al., 2011).

Environment Influences the Body Plan of Organisms
The distinction between adiata and Bilateria, or organisms with a radial or bilateral symmetry, is that the latter have a dorsal/ventral polarity resulting in bilateral body axes (reviewed by Martindale and Henry, 1998). By comparison, species with radial symmetry, the adiata, have a single anterior/posterior axis in their body plan and no dorsal/ventral polarity. Another general distinction is the presence of three germ layers in the Bilateria, which are the endoderm, ectoderm, and mesoderm. These three pluripotent cell types will give rise to organs and internal epithelial layers, skin and nervous tissues, and muscle and connective tissues, respectively.

First, they looked into the duration of postoperative ileus if gum was chewed following a cesarean section. Secondly they looked at whether there was a difference in the results when comparing patients who chewed sugar-free gum with the results of those who chewed gum with sugar substitute in it. In the experiment, 76 women were divided into three categories, the control group, the sugar-free gum group, and the group who were given sugar-substituted gum. The patients who got to chew gum did so every fifteen minutes starting two hours after their surgery. hat the researchers found was that there was no marked difference between the three groups in comparing the time it took to their first episode of…

Angiography;, Types Categories, , Signs & Symptoms, Treatment, Imaging Modality
An angiography involves the use of water-soluble X-ray contrast media by injecting it into blood streams in arteries or veins with the purpose of imaging blood vessels. The process is meant to observe normal or pathological conditions of the vessel organization. By seeing the lumen of blood vessels and organs, an angiography can provide information concerning conditions like luminal narrowing and aneurismal widening. Vessel access is essential and serious complications can appear if the substance is unable to pervade the veins and arteries, but this is rare and unlikely to occur. hile these are some of the conditions that are frequently detected through an angiography, it can also play an important role in analyzing sources of bleeding, tumors, and diverse malformations in veins and arteries.
The discovery of X-rays led to some of the first experiments with angiographies as…

The author of this report has been presented with a hypothetical situation where a forty-four-year-old patient has contracted scleroderma within her lung tissue. There are many implications to having this medical disorder and they are not limited to the medical realm. Indeed, this report will cover a number of these implications and byproducts including stereotyping by all of society including medical professionals, the overall predisposition for the disease, daily life of scleroderma, comorbidities that might exist or end up happing and social issues such finances, the environment and so forth. While there are a good number of things that can be done to mitigate, treat or even prevent scleroderma, there are a lot of implications that any scleroderma patient must face and it can be very difficult for the patient.
Scleroderma is rare but it can take on many forms. Indeed, while the patient in this…

Still, others claim that the physical resemblance of Lotus Root to the lungs holds the clue to understanding its healing properties ("Health enefits of Lotus Root"). Lotus Root is said to treat various respiratory problems. Small doses of the juice extracted from raw, finely grated Lotus Root is recommended for lung-related ailments such as tuberculosis, asthma, and coughing, for heart disease, and to neutralize toxins. Also, macrobiotic remedy combining Lotus Root and akuzu is often recommended to treat colds accompanied by fever and/or troubled stomach and intestines. Lotus Root is also said to be helpful for treating colds because it melts mucus accumulation in the respiratory system. When a Lotus Root plaster is applied to the face, it is believed to relieve sinus congestion and inflammation.

The National Park Service (NPS, 2008) explains that "Numerous scientific studies have reached a consensus: lead poisoning is the biggest threat facing the successful recovery of the California condor." The NPS asserts that "More than 500 scientific studies published since 1898 have documented that worldwide, 134 species of wildlife are negatively affected by lead," including condors.
Meanwhile, the leadership of the NRA -- an organization that indeed does a lot of good, and has millions of responsible hunters as members -- has attacked the science regarding lead poisoning and has taken the position that the law in California calling for non-lead ammunition in condor habitat areas is really an attempt to "ban firearms." That is ridiculous. This has always been the NRA mantra when gun safety advocates try to pass legislation: they're trying to take NRA members' guns away. This is a patently absurd but powerful piece of propaganda. As…

human DNA sequence composed of a series of letters such as 'accagacagt' and the objective was to decipher this jumble of letters and interpret the results. I suppose I should report that the process went smoothly and that after a bit of research I now consider myself an expert in regard to the new science of DNA Sequencing. However, I have a thousand more questions now than before I began and even the answers I came up with may or may not be correct. I do know for a fact that this is a pretty new art or science and its potential seems limitless. "DNA itself has thus far shown only modest evidence of possessing any intrinsic catalytic activities, although the prospect that more will be discovered in the future is surely plausible."

Obviously, enterokinase gene being tied to this chromosome entails a great deal of research interest into the biological functions of the gene and the manner by which it contributes to disease. Defects in PRSS7 therefore are a direct cause of enterokinase deficiency which is a life-threatening intestinal malabsorption disorder. The disorder can be characterized by severe bouts of diarrhea and failure to thrive and thus create a situation of initiating activation of pancreatic proteolytic proenzymes (trypsin, chymotrypsin and carboxypeptidase a).
Animals, like humans, have to handle digestion of exogenous macromolecules without destroying endogenous constituents so the serine protease or enterokinase seems to be a fundamental digestive system requirement. In other words, all vertebrates such as mice or dogs have adapted a two step enzymatic cascade that is used to change pancreatic zymogens over to active enzymes in the lumen of the gut as discovered by researchers in Pavlov's laboratory in the early 1900's. "Extracts of the proximal small intestine were shown strikingly to activate the latent hydrolytic enzymes in pancreatic fluid. Pavlov considered this intestinal factor to be an enzyme that activated other enzymes, or a 'ferment of ferments' and named it enterokinase." (Stone, 2002)
quality of indoor air has received and increasing amount of attention, including a large amount of discussion about sick building syndrome, which has been recognised since the 1970's. Certainly, most North Americans spend the majority of our lives indoors, and the quality of our indoor air environment has been shown to play a huge role on our health. A wide variety of indoor pollutants can have an effect on human health, including environmental tobacco smoke, volatile organic chemicals (VOCs) and biological pollutants. iological indoor pollutants include dust mites, cockroaches, effluvia from pets like birds, rodents, dog and cats and mold.
Early investigations into sick building syndrome often gave a multi-factorial explanation for the symptoms of occupants. However, these investigations often could not explain the long duration of effects. Further, investigations into indoor air quality have historically ignored the problem of mold, and failed to give a clear history of water…

Air pollution pertains to substances and gases in the air that threaten health and life. Among these are pollutants and irritants, such as nitrogen oxides, sulfur dioxide, and carbon dioxide; particulates, volatile organic compounds (VOCs), toxic substances and some natural substances, like pollen. ut most of the pollution comes from the by-products of industrialization - fossil fuel combustion, transportation, transportation, power plant emissions and those from other industrial processes. The burning of fossil fuels to generate electricity alone is the greatest source of air pollution in the U.S.A. These outdoor pollutants can undermine health and cause environmental disturbances, such as acid rain, and are toxic.

Mold Spore Trapping
Current Scientific Knowledge
People are exposed to aeroallergens in a variety of settings, both at home and at work. Fungi are ubiquitous airborne allergens and are important causes of human diseases, especially in the upper and lower respiratory tracts. These diseases occur in persons of various ages.
Airborne spores and other fungi particles are ubiquitous in nonpolar landscapes, especially amongst field crops, and often form the bulk of suspended biogenic debris. The term mold often is used synonymously with the term fungi. A more precise definition would specify that molds lack macroscopic reproductive structures but may produce visible colonies. Respiratory illness in subjects exposed to rust and dark-spored imperfecti fungi was described more than 60 years ago, and physicians worldwide now recognize a sensitization to diverse fungi.
Since fungus particles commonly are derived from wholly microscopic sources, exposure hazards are assessed largely through direct sampling of a…

It normalizes blood pressure by dilating the blood pathways throughout the body, destroys poisonous carbon dioxide, releases free oxygen and promotes higher metabolism and stimulated enzyme systems. Consuming chlorophyll from wheatgrass has been shown to be a very highly successful way to alkalize and energize the body (Wheatgrass Juice Benefits, 2010).
Wheatgrass has been used to treat a number of conditions including the common cold, coughs, bronchitis, fevers, infections, and inflammation of the mouth and throat. Many years ago, wheatgrass was used to treat cystitis, gout, rheumatic pain, chronic skin disorders, and constipation. Even though most people use wheatgrass juice as a dietary supplement, some proponents claim that a dietary program frequently called the wheatgrass diet can cause cancer to retreat and can actually extend the lives of people who have cancer. They believe that the wheatgrass diet strengthens the immune system, kills harmful bacteria in the digestive system, and…

This implies that decomposition process goes on activated by the young earthworms in the soil, given that the soil is loose, moist and rich in organic matter for the worms to remain alive. The bacterium which is present in the alimentary canal of the earthworm converts organic water to natural fertilizers. The chemical alterations that the organic wastes are put to consist of deorderising and neutralizing. This implies that the pH of the castings is 7 which is neutral. (the tasteful garden)

Diversity and Psychology
There were two major developments that influenced the field of psychology and the professions' views regarding multicultural competence, emphasized in 2003. The American Psychological Associations' 2002 Ethical Principles and Code of Conduct and the Guidelines on Multicultural Education, Training, Research, Practice and Organizational Change for Psychologists published in 2003 both stressed the importance of moving from a mono-cultural school of thought to a multicultural perspective and that these 'new rules' acknowledge an appreciation of differences as well as an "understanding of the inherent ambiguity and complexity in psychological practice (Pack-rown & Williams, 2003; Manesse, Saito, & Rodolfa, 2004). Knapp and VandeCreek (2003) said of these new guidelines that they articulate a need for greater sensitivity regarding linguistic and cultural minorities. The development of the new Code of Ethics and the APA's positioning were purported to be in response to a long awaited recognition of the need for…

Dermatology- The dermatology department deals mostly with skin related illnesses. The most common issues within this department pertain to skin, scalp, hair and nails. Many of our clients are female with more cosmetic needs. Many would like to retain their youthful appearance and believe minor surgery is the best solution. As such, our departments offer many cosmetic treatments including hair removal, hair transplants, laser therapy and tattoo removal. This past fiscal year has been quite difficult as many of our affluent clients have postponed treatment due to economic concerns with the U.S. We believe this trend to be transitory in nature, with a steady increase in treatments to occur in early 2012.
