Phenylketonuria Genetics samer kareem 1,265 Views • 3 years ago

Classical PKU is an autosomal recessive disorder, caused by mutations in both alleles of the gene for phenylalanine hydroxylase (PAH), found on chromosome 12. In the body, phenylalanine hydroxylase converts the amino acid phenylalanine to tyrosine, another amino acid.

Dental implant surgery.
Dental implant surgery. samer kareem 2,816 Views • 3 years ago

Dental implant surgery is a procedure that replaces tooth roots with metal, screwlike posts and replaces damaged or missing teeth with artificial teeth that look and function much like real ones. Dental implant surgery can offer a welcome alternative to dentures or bridgework that doesn't fit well. How dental implant surgery is performed depends on the type of implant and the condition of your jawbone. Dental implant surgery may involve several procedures. The major benefit of implants is solid support for your new teeth — a process that requires the bone to heal tightly around the implant. Because this healing requires time, the process can take many months.

Bovine Respiratory Disease
Bovine Respiratory Disease samer kareem 1,286 Views • 3 years ago

Bovine respiratory disease (BRD) has a multifactorial etiology and develops as a result of complex interactions between environmental factors, host factors, and pathogens. Environmental factors (eg, weaning, transport, commingling, crowding, inclement weather, dust, and inadequate ventilation) serve as stressors that adversely affect the immune and nonimmune defense mechanisms of the host. In addition, certain environmental factors (eg, crowding and inadequate ventilation) can enhance the transmission of infectious agents among animals. Many infectious agents have been associated with BRD. An initial pathogen (eg, a virus) may alter the animal’s defense mechanisms, allowing colonization of the lower respiratory tract by bacteria.

What is spinal decompression.?
What is spinal decompression.? samer kareem 981 Views • 3 years ago

Decompression is a surgical procedure that is performed to alleviate pain caused by pinched nerves (neural impingement). During a lumbar decompression back surgery, a small portion of the bone over the nerve root and/or disc material from under the nerve root is removed to give the nerve root more space and provide a better healing environment. There are two common types of spine surgery decompression procedures: Microdiscectomy Lumbar Microdiscectomy Microdiscectomy Surgery Video A microdiscectomy (a microdecompression) is typically performed for pain from a lumbar herniated disc. The surgery is considered reliable for leg pain caused by the herniated disc, most commonly called sciatica by patients, and most commonly referred to by medical practitioners as a radiculopathy.

Multiple Myeloma Mechanism of Action
Multiple Myeloma Mechanism of Action samer kareem 1,536 Views • 3 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

Huge Hydrocephalus
Huge Hydrocephalus samer kareem 2,714 Views • 3 years ago

Hydrocephalus can be fatal if left untreated. The damage to the brain can cause headaches, vomiting, blurred vision, cognitive problems, and walking difficulties. The term water on the brain is incorrect, because the brain is surrounded by CSF (cerebrospinal fluid), and not water.Oct 8, 2015

Proximal Humerus Plate
Proximal Humerus Plate samer kareem 1,282 Views • 3 years ago

This procedure describes proximal humeral fracture fixation with an angular stable plate (A). Sometimes, these implants are not available. Standard plates provide an alternative option, for example the modified cloverleaf plate (B). Presently, the specific indications, advantages, and disadvantages of angular stable and standard plates are being clarified. There is some evidence that angular stable plate provide better outcomes. In addition to type and technique of fixation, the quality of reduction, the soft-tissue handling, and the characteristics of the injury and patient significantly influence the results. There is no evidence that the use of angular stable plates will overcome these other factors.

How varicose veins form
How varicose veins form samer kareem 9,727 Views • 3 years ago

Varicose veins are generally benign. The cause of this condition is not known. For many people, there are no symptoms and varicose veins are simply a cosmetic concern. In some cases, they cause aching pain and discomfort or signal an underlying circulatory problem. Treatment involves compression stockings, exercise, or procedures to close or remove the veins.
