There is nothing that compares to the fresh-faced feeling you have when you leave the aesthetician after a facial. There is just something so freeing about knowing that nasty little buggers like blackheads, whiteheads and all other kinds of heads have been given the heave-ho. That could be why this Facebook video of a blackhead being removed has gone viral. With more than 24 million views, the popular video is weirdly difficult to stop watching.

Hypercalcemia
Hypercalcemia samer kareem 1,195 Views • 2 years ago

Hypercalcemia is a condition in which the calcium level in your blood is above normal. Too much calcium in your blood can weaken your bones, create kidney stones, and interfere with the way your heart and brain works. Hypercalcemia most commonly results from overactive parathyroid glands. These four tiny glands are each about the size of a grain of rice and are located on or near the thyroid gland. Other causes of hypercalcemia include cancer, certain other medical disorders, some medications, and excessive use of calcium and vitamin D supplements. Signs and symptoms of hypercalcemia may range from nonexistent to severe. Treatment depends on the underlying cause.

Multiple Myeloma Mechanism of Action
Multiple Myeloma Mechanism of Action samer kareem 1,503 Views • 2 years ago

The pathobiology of MM is complex and the root underlying cause of myeloma is the multistep genetic changes in the postgerminal center B cell. In addition, the bone marrow microenvironment plays a crucial role.[2] The interaction between myeloma cells and the microenvironment is mediated through adhesive interactions via cell-surface receptors, paracrine loops involving several cytokines, such as IL-6, VEGF and IL-10, and suppression of cell-mediated immunity.[2–4] IMiDs modulate many of these interactions leading to decreased myeloma cell growth and survival. Thalidomide was the first IMiD introduced to treat MM. It was initially synthesized in Germany in the late 1950s to treat insomnia and morning sickness. It was withdrawn from the market in 1961 because of its teratogenic effects. Its immunomodulatory properties were realized when it was observed to improve erythema nodosum leprosum, a painful immunologic reaction of leprosy, leading to its approval by the FDA in 1998 with tight prescribing and marketing regulations. Subsequent research showed the diverse mechanism of action of thalidomide including its immunomodulatory effect by inhibition of de novo IgM antibody synthesis,[5] modulation of the T-cell subset by increasing the T-helper cells, inhibitory effects on the TNF-α and antiangiogenic activity leading to its use in MM. Significantly higher response rates in combination with dexamethasone led to its approval in the treatment of newly diagnosed MM in 2006. Lenalidomide, a second-generation IMiD, was developed from the structural backbone of the thalidomide molecule by the addition of an amino group (NH2-) at position 4 of the phthaloyl ring and removal of the carbonyl group (C = O) of the 4-amino-substituted phthaloyl ring (Table 1).[6] In addition to immunomodulatory effects, other mechanisms of action have been described such as direct cytotoxicity via induction of apoptosis, inhibition of cell adhesion molecules and inhibition of growth signals that promote bone marrow angiogenesis

Multiple sclerosis (MS) affects the brain and spinal cord. Early MS symptoms include weakness, tingling, numbness, and blurred vision. Other signs are muscle stiffness, thinking problems, and urinary problems. Treatment can relieve MS symptoms and delay disease progression.

Management of COPD
Management of COPD samer kareem 1,975 Views • 2 years ago

The goal of COPD management is to improve a patient’s functional status and quality of life by preserving optimal lung function, improving symptoms, and preventing the recurrence of exacerbations. Currently, no treatments aside from lung transplantation have been shown to significantly improve lung function or decrease mortality; however, oxygen therapy (when appropriate) and smoking cessation may reduce mortality. Once the diagnosis of COPD is established, it is important to educate the patient about the disease and to encourage his or her active participation in therapy.

Fertilization and Implantation in human
Fertilization and Implantation in human samer kareem 3,110 Views • 2 years ago

Millions of sperms are deposited into the vagina during sexual intercourse. The sperms make their way through the cervix into the uterus and then on to the fallopian tubes. As they swim along this way their numbers decline. Only a few hundred sperm will get close to the egg. During the trip, sperm prepare themselves to meet the egg by subtle alterations of their heads and movement patterns. Once inside the fallopian tube, the sperm attracts the egg by releasing a chemical. The egg is surrounded by a protective covering called the zona pellucida, which allows only one sperm to penetrate it. Once inside the egg, the head of the fertilizing sperm releases its genetic contents, which fuses with the nucleus of the egg. Fertilisation is now complete. Sperm are able to survive for 2-3 days within the female's reproductive tract. The length of the time that a woman's egg can be fertilized by a man's sperm ranges from 12-24 hours.
