Melanocyte

is seen in people within 3-14-day treatment using the topical steroids and this cause thinning the skin layers with reducing the cell size. If this use for a long time it can affect the synthesis of the skin protein and inhibit the formation of melanocytes, which causing localized depigmentation. Plus, it also causes wrinkled and transparent skin as well as the underlying veins and capillaries become visible. Topical steroids were used to suppress the…

luteinizing hormone, which regulates ovulation timing and promotes sperm and egg development, follicle-stimulating hormone and sex hormone. Other hormones produced in the pituitary gland include; dopamine, which functions to inhibit prolactin releases, melanocyte-stimulating hormone useful in skin pigmentation, and the human growth hormone. The pineal gland, on the other hand, produces melatonin hormone, which is responsible for skin pigmentation. This gland is, however, controlled by…

The role of circadian rhythms and clock genes in cutaneous wound healing Introduction The governing of rhythmic changes involved in daily behaviour and/or physiology is controlled by light/dark cycles. The field of Chronobiology encompasses biological timings (hormone secretion, blood pressure, reproductive cycles, body temperature, sleep, locomotor activity). Circadian rhythms have been discovered to play a major role in the mental, physical and behavioural changes, which follow a 24 hour…

embryo. This denoted a risk of mutations which L. Andersson refers to In Genome-wide association analysis in domestic animals, regarding white spotting due to varying combinations of mutations that ultimately affect MITF expression. MITF regulates melanocyte, and mutations of this gene are associated with severe pleiotropic effects targeting hearing and vision. However, Sunny’s alert behavior has shown no disabilities from MITF mutation. A small fraction of Shetland sheepdog accounts for the…

Adrenal insufficiency so called Addison Disease is an endocrine condition defined as the inadequate production or action of glucocorticoids, principally a steroid hormone called cortisol. The adrenal insufficiency is a rare condition in childhood, but it carries the risk of adrenal crisis in the event of a child becoming unwell as a result of intercurrent illness, injury or surgery. Pathophysiology The adrenal glands have many functions contributing to homeostasis in the body. This is one of the…

system, which includes two populations of neuron located in the arcuate nucleus, that express the proopiomelanocortin propeptide (POMC) and agouti-related protein (AgRP) (Roseberry, Stuhrman et al. 2015). POMC propeptide is the precursor to the melanocyte-stimulating hormones (α, β, and γ-MSH) (Roseberry, Stuhrman et al. 2015). The melanocortin system plays a significant role in controlling feeding and body weight (Roseberry, Stuhrman et al. 2015). It is done through the POMC and AgRP neurons,…

Sunglasses at MBIS? Do you wear sunglasses? Well, at MBIS you don’t. Students at MBIS should be able to wear sunglasses at school because it can prevent eye damage and eye cancer. We should also examine why we shouldn’t to get a balanced view. Teachers at MBIS wear sunglasses, but kids aren’t allowed. Us kids are the future. Sunglasses protect the skin around your eyes. The skin around your eyes, including your eyelids, is the thinnest and most sensitive skin on your body which means that it…

Tanning beds give off UV lights or radiation. When your skin is exposed to UV rays, it is the reaction to make more melanin. This makes the skin darker. The two types of radiation that enter the skin is UVA and UVB rays. UVB hits the top of the skin and are more responsible for most sunburns. UVA rays mostly target deeper layers of the skin. They can cause allergic reactions, and rashes. If you put the two rays together…

different types of cancer. Most of the cancer are named based on the organ where these abnormal cell division started. For example, if these uncontrollable cell division started at the breast, it is called breast cancer, if the cancer started in the melanocytes of the skin, it is call the melanoma cancer. Now, what is telomerase? Telomerase is a type of ribonucleoprotein enzyme in the human body that mediates RNA-dependent synthesis of telomeric repeats in species ranging from yeast to human.…

relatively a consistently high number of white blood cells are a symptom of leukemia. Leukemia is a cancer of the blood where the patient has about 50,000 white blood cells in a single drop of blood. Normally, a drop of a blood can contain anywhere from 7,000 to 25,000 white blood cells at a time. The blood platelet or thrombocytes are the smallest blood cells. Their number ranges from 20,000 to 500,000 per cubic millimeter of blood. Platelets are useful to the body because they contain…
