Enzyme allows B cells to resist death, leading to leukemia

B cell chronic lymphocytic leukemia (B-CLL)is the most common leukemia in adults and is characterized by theprogressive accumulation of mature B lymphocytes in the blood, bonemarrow, and lymphatic tissues. It is believed that in the early stagesof disease, B-CLL is the result of an undefined defect in theprogrammed signals that trigger normal B cell death (apoptosis). LivioTrentin and colle...

Nano-Probes Allow an Inside Look at Cell Nuclei

Nanotechnology may be in its infancy, but biologists may soon use it to watch the inner workings of a living cell like never before. Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Lawrence Livermore National Laboratory have developed a way to sneak nano-sized probes inside cell nuclei where they can track life's fundamental processes, such a...

Tiny scaffolding allows stem cells to become working fat cells

Researchers here have used a new microscopic, three-dimensional scaffolding to coax mouse stem cells to transform themselves into fat cells, and then to function identical to how fat cells naturally do in the body. While other studies have previously grown fat cells, or adipocytes, in the laboratory, those cells never completely functioned in the same way they do in normal tissue. They fai...

Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin

Nano-sized particles embedded with bright, light-emitting molecules have enabled researchers to visualize a tumor more than one centimeter below the skin surface using only infrared light. A team of chemists, bioengineers and medical researchers based at the University of Pennsylvania and the University of Minnesota has lodged fluorescent materials called porphyrins within the surface of a polyme...

New operation for swallowing problems

An ingenuous technique which reshape the throat area helps people who cannot swallow because of paralysis. Swallowing is a very complex operation, involving the co-ordinated action of various of the cranial nerves. One of these, the vagal nerve, controls the swallowing at the upper end of the digestive tract// - that is, above the esophagus, but below the mouth. When this nerve is paralys...

Swallowing Magnets Found To Be Dangerous for Kids

Swallowing foreign objects is a common occurrence among children between 6 months and 3 years old. About 80 percent of objects // that reach the stomach will pass through the gastrointestinal tract on their own. However, up to 20 percent will need to be surgically removed. Children who swallow more than one magnet need immediate medical attention. Researchers say if magnets are allowed t...

Swallowing Exercises Helps With Cancer Treatment Recovery

Chemo-and-radiation therapies make head-and-neck cancer patients feel as if they have been drinking scalding coffee for weeks. Anticipating that the treatment may later cause difficulty swallowing, doctors usually order a temporary // feeding tube through the stomach wall. This however sometimes can cause more difficulty with swaloowing. But UAB head-and-neck surgeon William R. Carroll...

Financial Allowances Being Offered To Poor Vietnamese HIV Carriers

The Vietnamese Government which intends to stabilize the rates of HIV by the year 2020 has proposed to offer allowances worth atleast 4.1 US dollars to HIV infected individuals on a monthly basis//. It has also been planned to reduce the rate of HIV infection to below 0.3 percent by 2010. The current projected population of Vietnam approximates to nearly 82 million. Under a recent gov...
