inhibits gastric acid secretion as well as pepsin and gastrin output (PubChem, 2017). Pseudoephedrine: Pseudoephedrine is a phenethylamine that is used mainly for respiratory tract decongestion. Pseudoephedrine displaces norepinephrine from storage vesicles in presynaptic neurones, thus releasing norepinephrine into the neuronal synapses where it stimulates primarily alpha-adrenergic receptors. This receptor stimulation results in vasoconstriction and decreases nasal and sinus congestion…

Eukaryotic cells are cells whose nucleus is bound by a membrane; these cells contain organelles, which are structures each enclosed within its own membrane found only in eukaryotic cells, each organelle has a specific function inside a cell. One type of organelle is a lysosome, which are the organelles that dispose of waste and toxins. Lysosomes are fluid filled sacks which range in size from 0.1 to 1.2 micrometres and contain around fifty degradative enzymes that enable it to effectively…

RESEARCH STRATEGY (a) Significance. Yersinia pestis (Yp) is a Gram-negative bacterial pathogen that is the causative agent of plague. Yp is a Category A agent defined by the National Institute of Allergy and Infectious Diseases (NIAID) as a pathogen that is high risk to public health and national security. A long term goal of NIAID is to explore the host-pathogen interaction and host response to infection with Yp, and to identify and characterize immune responses after exposure to Yp (1).…

Problem Polymeric nanoparticle to treat Breast Cancer: Abraxane, Albumin-based nanoparticle loaded with Paclitaxel. Introduction Cancer in general is when abnormal cells start growing out of control. These abnormal cells have gone through a mutation in the genome and have lost their ability of growth checkpoint. This means the cells had changes in their DNA and instead of repairing the damage or dying, it continues to divide thus leading to cancer because of faulty cells. The damage to…

In order to determine the sequence of events that occurred at a crime scene it is important to be able to determine and identify certain bodily fluids versus non-human substances. Based on the location of the biological evidence and its DNA can provide crucial information about the crime scene, its victim, and the suspect(s). These tests divided between presumptive and confirmatory testing. Blood evidence is the most common type bodily fluid found at a crime scene. Presumptive testing at the…

● seminal vesicles: D. How is the cat uterus modified to carry several fetuses (if you had a male cat refer to the picture on Page 107 of the dissection manual)? The uterus is bicornuate or y-shaped with two uterine horns. The enlarged size of the uterus allows…

All living organisms, including humans, reproduce to ensure the survival of their species. The male and female reproductive systems are essential for reproduction. The main purpose of the male reproductive system is to produce and deliver sperm into the female reproductive system. The main purpose of the female reproductive system is to produce egg cells and to nurture a fertilized egg so it is able to develop into a fetus. The male and female reproductive systems are distinct from one another…

The simple but revolutionary organism Drosophila melanogaster has intricate properties that are studied to find its relations with human genes. Not only is D. melanogaster a model organism for its rapid growth, inexpensive culturing, and easy modifications, the Drosophila can provide more in-depth scientific analysis that can solve human diseases. The model organism D. melanogaster is studied to find ground-breaking research in neurology, sleep, cancer, and drug discovery. The multivariable…

an increase in ATP. This ATP increase goes on to inhibit an ATP sensitive potassium channel (KATP channel) [17]. This then leads to the membrane becoming depolarised which triggers an influx of Ca2+ ions. These Ca2+ ions cause the migration of a vesicle containing insulin to move to the plasma membrane which then releases…

intro The purpose of this essay is to identify what symptoms may occur in a person or animal which is suffering from renal failure? And what are the options for treatment in both humans and animals as well as determining which method of treatment fits best for the situation. To understand renal failure an understanding of the renal system is necessary, although renal failure is mainly associated with the kidneys. The renal system consisting of the kidneys, bladder and urethra is responsible for…
