HIV Virus Life Cycle and Drug Reaction
HIV Virus Life Cycle and Drug Reaction Magdy 11,472 Views • 3 years ago

Binding and Fusion: HIV begins its life cycle
when it binds to a CD4 receptor and one of two
co-receptors on the surface of a CD4+
Tlymphocyte. The virus then fuses with the host
cell. After fusion, the virus releases RNA, its
genetic material, into the host cell.

Reverse Transcription: An HIV enzyme
called reverse transcriptase converts the singlestranded HIV RNA to double-stranded HIV DNA.

Integration: The newly formed HIV DNA
enters the host cell's nucleus, where an HIV
enzyme called integrase "hides" the HIV DNA
within the host cell's own DNA. The integrated
HIV DNA is called provirus. The provirus may
remain inactive for several years, producing few or
no new copies of HIV

Transcription: When the host cell receives a
signal to become active, the provirus uses a host
enzyme called RNA polymerase to create copies of
the HIV genomic material, as well as shorter
strands of RNA called messenger RNA (mRNA).
The mRNA is used as a blueprint to make long
chains of HIV proteins.

Assembly: An HIV enzyme called protease cuts
the long chains of HIV proteins into smaller
individual proteins. As the smaller HIV proteins
come together with copies of HIV's RNA genetic
material, a new virus particle is assembled.

Budding: The newly assembled virus pushes out
("buds") from the host cell. During budding, the new
virus steals part of the cell's outer envelope. This
envelope, which acts as a covering, is studded with
protein/sugar combinations called HIV
glycoproteins. These HIV glycoproteins are
necessary for the virus to bind CD4 and coreceptors. The new copies of HIV can now move
on to infect other cells.

Stephen Slade shows a 1 week post op patient after DSAEK. DSAEK is an excellent option for many patients with corneal disease. In DSAEK, only the thin, inner layer is replaced, so the healing is typically much faster than a full thickness cornea graft.

enile implants are devices placed inside the penis to allow men with erectile dysfunction (ED) to get an erection. Penile implants are typically recommended after other treatments for ED fail. There are two main types of penile implants, semirigid and inflatable.

External Jugular Vein IV
External Jugular Vein IV samer kareem 8,126 Views • 3 years ago

External jugular vein cannulation is an integral part of modern medicine and is practiced in virtually every health care setting. Venous access allows sampling of blood, as well as administration of fluids, medications, parenteral nutrition, chemotherapy, and blood products. [1] This topic describes placement of an intravenous (IV) catheter into the external jugular vein. A similar technique can be used for placement of IV catheters at different anatomic sites.

RARE Open Appendectomy Video

An appendectomy (sometimes called appendisectomy or appendicectomy (British English)) is the surgical removal of the vermiform appendix. This procedure is normally performed as an emergency procedure, when the patient is suffering from acute appendicitis. In the absence of surgical facilities, intravenous antibiotics are used to delay or prevent the onset of sepsis; it is now recognized that many cases will resolve when treated perioperatively. In some cases the appendicitis resolves completely; more often, an inflammatory mass forms around the appendix, causing transruptural flotation. This is a relative contraindication to surgery.

Bariatric surgery
Bariatric surgery samer kareem 8,353 Views • 3 years ago

Bariatric surgical procedures cause weight loss by restricting the amount of food the stomach can hold, causing malabsorption of nutrients, or by a combination of both gastric restriction and malabsorption. Bariatric procedures also often cause hormonal changes. Most weight loss surgeries today are performed using minimally invasive techniques (laparoscopic surgery). The most common bariatric surgery procedures are gastric bypass, sleeve gastrectomy, adjustable gastric band, and biliopancreatic diversion with duodenal switch. Each surgery has its own advantages and disadvantages.

Peripheral Laser Atherectomy
Peripheral Laser Atherectomy samer kareem 3,365 Views • 3 years ago

Peripheral arterial disease (P.A.D.) occurs when plaque (plak) builds up in the arteries that carry blood to your head, organs, and limbs. Plaque is made up of fat, cholesterol, calcium, fibrous tissue, and other substances in the blood. When plaque builds up in arteries, the condition is called atherosclerosis (ATH-er-o-skler-O-sis). Over time, plaque can harden and narrow the arteries. This limits the flow of oxygen-rich blood to your organs and other parts of your body. P.A.D. usually affects the legs, but also can affect the arteries that carry blood from your heart to your head, arms, kidneys, and stomach. This article focuses on P.A.D. that affects blood flow to the legs.

Methotrexate for Rheumatoid Arthritis
Methotrexate for Rheumatoid Arthritis samer kareem 1,747 Views • 3 years ago

Methotrexate works by reducing the function of the cells that are causing inflammation in the joint tissues. "Its use can reduce inflammation and therefore should help relieve pain and protect from joint damage," notes Sean A. Whelton, MD, a rheumatologist and associate professor of medicine at MedStar Georgetown University Hospital in Washington, D.C. Less inflammation in the joints should mean less joint pain and less joint swelling. You should also feel less fatigue and less morning stiffness.
