Pathophysiology Tinea pedis, or athlete’s foot, is the term used for a dermatophyte infection of the sole of the foot and interdigital spaces (Porth, 2015). This infection is most commonly caused by Trichophyton rubrum, initially endemic to a small region of Southeast Asia. Dermatophytes are fungi that require keratin for growth. The fungus that causes tinea pedis falls under this umbrella. Other causes of tinea pedis include: Trichophyton mentagrophytes and Epidermophyton floccosum. The…

According to Comer, depression is a clinical disorder that causes considerable distress and impairment and features a range of symptoms, including emotional, motivational, behavioral, cognitive, and physical symptoms. Nevertheless, the picture of depression may vary greatly from person to person. Depression differs from sadness, in that sadness is context-specific, is proportional to the triggering loss, and ends when the loss situation ends (Comer, 2015). Due to the fact that the biological…

The purpose of the homeostatic system is to maintain a stable environment despite fluctuations in the external environment, homeostasis meaning ‘same state’. Glucose homeostasis refers to maintaining blood glucose levels in the human body. Glucose is one of the most important energy sources. For various tissues in the body, such as the brain, glucose is the only substance used. It is important that there is a continuous supply of glucose for this reason. For homeostasis of the internal…

Myasthenia Gravis Background Myasthenia gravis is a Type II autoimmune disorder in which antibodies form against various types of receptors, kinases, or proteins (1). There are four subtypes of myasthenia gravis, with the most prevalent subtype being due to autoantibodies against the muscle-type acetylcholine receptor, AChR, at the neuromuscular junction (2; 3). The second subtype involves antibodies against the muscle-specific kinase, MuSK, and the third type is due to autoantibodies against…

F214 Communication, Homeostasis and Energy Module 2 Excretion 4.2.1 Excretion a. Define the term excretion Excretion-The removal of metabolic waste from the body which are by products or unwanted substances from cell processes. b. Explain the importance of removing metabolic wastes, including carbon dioxide and nitrogenous waste from the body Carbon dioxide Excess carbon dioxide is toxic and has three main effects: The majority of carbon dioxide is carried in the blood as…

Neurons are the cells specialized to receive, conduct, and transmit signal to the nervous system. The development of neurons starts early during the embryogenesis. After the fusion of sperm and egg, zygote is formed which is further divided to form blastula eventually leading to gastrula stage of development. Gastrulation begins as invagination of cells in the embryo leading to the formation of three germ layers. Formation of notochord from the mesodermal layer marks the beginning of neurulation…

The role of oxysterols in human body and disease 1. Introduction Oxysterols are 27-carbon derivatives of cholesterol created by spontaneous or enzymatic oxidation (Figure 1, (Brown and Jessup, 2009)). The oxidation of cholesterol occurs either on the side chain or on the sterol core. Side chain oxidation generates, e.g., 24-hydroxycholesterol (24-HC), 25-hydroxycholesterol (25-HC) or 27-hydroxycholesterol (27-HC) while the core oxidation gives rise to ring oxysterols, mostly ring-B oxysterols,…

44. There is a recently discovered hormone known as Ghrelin. 1) Please explain the role this hormone is thought to play in the weight loss that occurs after stomach-reduction surgery. 2) Please analyze and decide for yourself whether it plays a decisive role, or not. (6pts) After stomach reduction surgery, the stomach would “stretch” even with a small amount of food, and therefore signal the release of the leptin hormone, which counters the ghrelin hormone, that stimulated the…

Every year one in six Americans get food poisoning . Food poisoning occurs due to the contamination of food through microorganisms. Botulism is a form of food poisoning caused by the microorganism Clostridium botulinum. Clostridium botulinum is a gram-positive bacterium, bacillus in shape, and is an obligate anaerobe.1 The bacterium can produce endospores, making it resistant to microbial control methods. Clostridium botulinum survives in nonliving reservoirs1 . It is commonly found in soil and…

Stem Cell research has been advancing a lot in recent years and there have been many discoveries that have aided in furthering the research about cancer and how to cure it. They are the next big breakthrough in science and show a promising future. With enough time and research, scientists will be able to utilize stem cells in a way that will be beneficial to cancer patients. Cancer is known as a group of diseases involving abnormal cell growth that has the potential to spread or invade to other…
