Multiple Myeloma Mechanism of Action
Multiple Myeloma Mechanism of Action samer kareem 1,525 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 It was withdrawn from the market in 1961 because of its teratogenic effects.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

Plaque Removal
Plaque Removal samer kareem 9,897 Views • 2 years ago

Preventing heart attacks and stroke can involve extensive surgery to remove plaque from your arteries, but as FOX17's Nick Paranjape shows us, there's a new procedure in Middle Tennessee that is less invasive and substantially cuts down on your recovery time. At 76, Jimmy Wilkie of Hendersonville exercises on his treadmill 3-4 times a week. Recently, he started having pain in his left leg. It was so bad, he couldn't even walk. Turned out, Mr. Wilkie had a blocked artery in his leg. In years past, this would've required major bypass surgery. Not anymore!"The Turbohawk Catheter has really opened a new door for us," says Dr. Dan Wunder.Dr. Wunder, an Interventional Radiologist at Premier Radiology in Madison, is talking about the Turbohawk. It's a device which is inserted into the blocked artery, and inside the Turbohawk are 4 tiny blades."It can cut the plaque and with that shape of the disc it cuts with it pushes it forward into the catheter," says Dr. Wunder.The one-hour procedure doesn't just push the plaque to the sides where it can re-grow, but instead grabs it and removes it!"We pull it back out and it fills up," says Dr. Wunder. "Empty it out, go back down and we can cut some more out."Before and after images really say it all."They used a roto rooter as he called it," says Wilkie.A roto rooter, Turbohawk, call it what you want, but Wilkie says all he knows is the procedure worked right away!"There wasn't any pain at all in my leg," says Wilkie.It's rare, but the outpatient procedure can have complications like plaque getting pushed down in the leg. Dr. Wunder says the main symptoms of a blockage in your legs is having severe pain or cramping when you're walking or exercising.

Dental implant surgery.
Dental implant surgery. samer kareem 2,805 Views • 2 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.

Meniscus Tear repair
Meniscus Tear repair samer kareem 5,974 Views • 2 years ago

A torn meniscus is one of the most common knee injuries. Any activity that causes you to forcefully twist or rotate your knee, especially when putting your full weight on it, can lead to a torn meniscus. Each of your knees has two menisci — C-shaped pieces of cartilage that act like a cushion between your shinbone and your thighbone. A torn meniscus causes pain, swelling and stiffness. You also might feel a block to knee motion and have trouble extending your knee fully. Conservative treatment — such as rest, ice and medication — is sometimes enough to relieve the pain of a torn meniscus and give the injury time to heal on its own. In other cases, however, a torn meniscus requires surgical repair.

Quick Fingernail Test for Diabetes
Quick Fingernail Test for Diabetes samer kareem 83,369 Views • 2 years ago

A simple test of fingernail clippings could replace a blood draw as a way to diagnose and monitor type 2 diabetes mellitus (T2DM), with huge implications for tracking the disease in the developing world. Research on this method by a team of Belgian researchers was reported July 28, 2015, at the 2015 American Association for Clinical Chemistry (AACC) Annual Meeting and Clinical Lab Expo in Atlanta. The team, led by Joris R. Delanghe, MD, PhD, of the Department of Global Chemistry, Microbiology and Immunology at Ghent University, collected nail clippings from 25 people with T2DM and 25 without the disease. The clippings were ground into a powder and tested with an inexpensive FT-IR photometer to measure how much the protein in the nails had bonded with sugar molecules, a process known as glycation. “We found a striking difference in the measurements between the control group and the patients with diabetes,” Delanghe said. In an interview with Evidence-Based Diabetes Management, he said replacing the standard blood test to measure glycated hemoglobin is a huge advantage. In many cultures, he said, “Taking blood is something that cannot be tolerated.” - See more at: http://www.ajmc.com/journals/evidence-based-diabetes-management/2015/september-2015/fingernail-tests-may-offer-cheap-simple-way-to-diagnose-diabetes#sthash.XQxnBcNO.dpuf
