Brazil Zika Virus Epidemic

Words: 2450 Length: 8 Pages Document Type: Essay Paper #: 43047936

The Zika virus has come to the United States. A virus from the Flaviviridae, is spread via the A. albopictus or A. aegypti mosquitoes that feed and transmit the virus to humans during feeding. Related to the West Nile, yellow fever, and dengue viruses, it spread eastward and eventually made its way to the Americas where it created the 2015-16 Zika virus epidemic. While the virus itself does little to the person infected, it can have horrible and permanent consequences for the child that was born while exposed to the virus.
Microcephaly is a common birth defect in babies exposed to the Zika virus. They may even be born with a partially collapsed skull. Babies exposed to the virus may also experience severe brain deformations leading to lifelong disability for the infant. There is hope however. The Zika virus vaccine is in the works and people may receive vaccinations within…… [Read More]

The Human Genome Project Chromosome Abnormality

Words: 690 Length: 2 Pages Document Type: Essay Paper #: 40638043

The Human Genome Project was the global, collaborative research program with the main purpose of completing the mapping and comprehension of all the genes of human beings. In delineation, genome encompasses all of the genes put together (National Human Genome Research Institute, 2018). The undertaking of the Human Genome Project has permitted researchers to start to comprehend the scheme and outline for building a person. With the progression and advancement of learners gaining more information regarding the functions of genes as well as proteins, this insight will have significant influence in the fields of life science, medicine as well as biotechnology (National Library of Medicine, 2018). The major accomplishment of the Human Genome Project is that in 2003, researchers made the proclamation that the Human Genome Project had finished a sequence of high quality of fundamentally the whole human genome. In addition, this sequence filled the holes from a working…… [Read More]

Gastrointestinal Tract Disorders of Motility

Words: 1175 Length: 4 Pages Document Type: Essay Paper #: 36022790

The Normal Pathophysiology of Gastric Acid Stimulation and Production
In the words of Phan, Benhammou, and Pisegna (2015), “gastric acid secretion by parietal cells occurs in the fundus of the stomach, and is intricately regulated by various neuronal (vagal), paracrine (histamine, somatostatin) and hormonal factors” (387). As the authors further point out, there are two key phases in gastric acid secretion. These are the cephalic phase and the gastric phases. While the former takes place as a consequence of neurological signals and prior to the entry of food in the stomach, the latter phase could be conceptualized as the period involving the activation of gastric activity in the stomach after food is swallowed. More specifically, gastric secretion in the cephalic phase is the result of several factors including, but not limited to the smell, thought or taste of food. Thus, it follows that this is largely a conditioned reflex. Its…… [Read More]
