A negative feedback loop is a system the body utilizes to reverse changes within an organized condition (Tortora, 2012). Within a negative feedback loop, an opposition to change takes place within the body. The change originates a response which brings the body back into an average range. Negative feedback groups include receptors, effector, and a…

Skin cancer is one of the most common and well-known cancers. Although it is typically easiest to cure, there are still many cases where a form of skin cancer has no definite cure. This difficulty is common with skin cancers that are not well known, such as Kaposi’s sarcoma. KS is an unusual malignancy discovered in 1981 during the beginning of the global HIV pandemic. During this time, cases of KS were rare. According to The American Cancer Society, “there were only two cases of KS found for…

By Jonas Wilson, Ing. Med. Lichen striatus Lichen striatus (LS), also known as Blaschko linear acquired inflammatory skin eruption or linear lichenoid dermatosis, is a benign, rare and self-limiting inflammatory skin condition. It primarily affects children between the ages of 5 to 15 years. LS initially presents as pinkish-red or flesh colored spots that coalesce over a two-week period (or less) to form a dull and scaly linear band. Lesions associated with LS tend to occur more frequently…

out faulty signals that speed up the growth cycle of skin cells. It is not contagious,yet is the most common autoimmune disease in the United states, affecting as many as (7.5) million Americans. Psoriasis has been linked to other serious health conditions, such as cardiovascular disease and depression. About 30 percent of people with psoriasis develop psoriatic arthritis, which causes pain, stiffness and swelling in and around the joints (Taylor et al,2006). Psoriatic arthritis can…

Abstract Lupus is a chronic autoimmune disease in which the human immune system is overactive. Chronic means that the signs and symptoms tend to last longer than six weeks and can last up to several years (Lupus Foundation of America, 2014). Autoimmune means the immune system cannot tell the difference between foreign invaders and healthy tissues within the body. Therefore, the body attacks itself by creating auto-antibodies that destroy the remaining healthy tissue (Lupus Foundation of America,…

These side effects include bone marrow suppression, nausea and vomiting and liver inflammation. Overall MTX is an effective medication for patients whose SLE has not responded to prior treatments and/or those who have cutaneous and articular manifestations of the…

Therefore, if these responses and behavioral mechanisms such as seeking shade in the heat, are able to restore the balance in the body temperature, it is detected by the thermoreceptors and relayed back to the thermoregulatory centre. But in a prolonged exposure to high environmental temperature, body temperature cannot be restored by negative feedback control because the mechanisms of homeostasis become over-whelmed, then the normal biochemical and physiological balance in the body is lost.…
