Researchers discover manipulation of microRNA-29a shows potential of novel IBS treatment

A possible cause of irritable bowel syndrome has been traced to a small piece of RNA that blocks a substance protecting the colon membrane, leading to hostile conditions that can produce diarrhea, bloating and chronic abdominal pain.New research shows that this RNA segment sends signals that stop the activity of the gene that produces glutamine, an amino acid. Previous research has linked a shortage of glutamine in the gut with the seepage of toxins and bacteria through the intestinal wall, irritating nerves and creating disease symptoms.

Alphavirus vector induce immune responses in people with advanced cancer: Researchers

There are several challenges to be overcome if therapeutic anticancer vaccines, which are designed to boost the patient's anticancer immune response, are to be successfully developed. For example, the viruses used to deliver the tumor protein to the patient's immune system are themselves targeted by the patient's immune system, inducing neutralizing and suppressive responses. But now, a team of researchers, led by Michael Morse, at Duke University Medical Center, Durham, has developed a way to overcome these neutralizing and suppressive responses by using an alphavirus packaged in virus-like replicon particles.

Neuroglobin may protect against Alzheimer's disease: Study

A team of scientists at the University of California, Davis and the University of Auckland has discovered that neuroglobin may protect against Alzheimer's disease by preventing brain neurons from dying in response to natural stress. The team published the results of their study in the April, 2010 issue of Apoptosis.

Octapharma USA receives confirmation of orphan drug exclusivity from FDA for wilate

Octapharma USA has received confirmation of orphan drug exclusivity from the U.S. Food and Drug Administration for wilate (von Willebrand Factor/Factor VIII Concentrate, Human), the replacement therapy developed specifically for von Willebrand Disease. The approval comes from the FDA Office of Orphan Products Development, which helps to advance the development of products that demonstrate promise for the treatment of rare diseases.

Research findings could lead to new drugs that reduce severity of blood infections leading to sepsis

Scientists have made an important discovery that could lead to new drugs that reduce the severity of blood infections leading to sepsis. Research presented in the August 2010 issue of Journal of Leukocyte Biology shows how interfering with the function of the cell membrane protein called "Programmed Death 1" (PD-1) improves survival in a clinically relevant model of severe infection.

Researchers discover mechanism linking H. pylori infection and stomach cancer

Researchers have discovered a mechanism by which Helicobacter pylori, the only known cancer-causing bacterium, disables a tumor suppressor protein in host cells.The new study, in the journal Oncogene, reports the discovery of a previously unknown mechanism linking H. pylori infection and stomach cancer, the second leading cause of cancer deaths worldwide.

Jenkins wins three man weight loss challenge by Dr. Siegal's Cookie Diet weight-loss regimen

New York Jets defensive tackle Kris Jenkins has won the three-man weight-loss challenge proposed by Head Coach Rex Ryan back in May, defeating Ryan and teammate Damien Woody. Jenkins lost 33 pounds compared to 26 pounds for Woody and 20 pounds for Ryan. A four-time NFL Pro Bowl athlete, Jenkins weighed 390 pounds at the start of the competition and now weighs in at a lean 359 pounds. To help insure his victory, Jenkins had recruited renowned physician, author, and weight-loss expert Dr. Sanford Siegal and followed the Miami physician's popular Dr. Siegal's Cookie Diet weight-loss regimen.

microRNA protects red blood cells from oxidant stress: Study

Pediatric researchers have discovered a new biological pathway in which small segments of RNA, called microRNA, help protect red blood cells from injury caused by chemicals called free radicals. The microRNA seems to have only a modest role when red blood cells experience normal conditions, but steps into action when the cells are threatened by oxidant stress.

Researchers create artificial RNA inhibitor to block excess blood cells formation

Researchers at UT Southwestern Medical Center have uncovered a key step in the creation of new red blood cells in an animal study.They found that a tiny fragment of ribonucleic acid (RNA), a chemical cousin of DNA, prompts stem cells to mature into red blood cells. The researchers also created an artificial RNA inhibitor to block this process.

Self assembly approaches to improve DNA sequencing

In an innovation critical to improved DNA sequencing, a markedly slower transmission of DNA through nanopores has been achieved by a team led by Sandia National Laboratories researchers.Solid-state nanopores sculpted from silicon dioxide are generally straight, tiny tunnels more than a thousand times smaller than the diameter of a human hair. They are used as sensors to detect and characterize DNA, RNA and proteins. But these materials shoot through such holes so rapidly that sequencing the DNA passing through them, for example, is a problem.

Patients with malignant gastrointestinal disease show high prevalence of malnutrition

Malnutrition is an important factor, influencing both morbidity and recovery after surgery. The early detection of nutritional risk would allow early intervention, which may prevent later complications. A traditional nutritional assessment often includes dietary and medical evaluations to identify significant weight loss over time, significantly low or high body weight(BW), skinfold thickness, serum nutritional factor levels and functional measurements of muscle strength.

Resveratrol suppresses inflammation in humans: Research

Resveratrol, a popular plant extract shown to prolong life in yeast and lower animals due to its anti-inflammatory and antioxidant properties, appears also to suppress inflammation in humans, based on results from the first prospective human trial of the extract conducted by University at Buffalo endocrinologists.

Researchers suggest soybean isoflavones enhance bone health

Scientists already know much about the more than 200 bones that make up your body. But mysteries remain regarding the exact role that many natural compounds in foods might play in strengthening our skeletons. Those compounds include estrogen-like substances known as soybean isoflavones.

Scientists identify enzyme to prevent beta-amyloids formation in Alzheimer patients

The brains of Alzheimer patients have high accumulations of the material beta-amyloid, which appear in the form of plaques. The precursors of these plaques are believed to be the underlying cause of the nerve cell loss that leads to the disruptions in memory that characterize Alzheimer's disease. The main aim of many Alzheimer therapies is therefore to inhibit the formation of beta-amyloid. Since beta-amyloid is cleaved from the so-called amyloid precursor protein (APP), scientists have focused on stopping the two enzymes that attack the precursor protein. These act like molecular scissors and cut out the beta-amyloid fragment. Blocking these scissors precludes the formation of beta-amyloid.

CD74 can serve as prognostic marker for colorectal cancer

CD74 is a protein that is expressed in and on cells of the immune system, such as B lymphocytes and antigen presenting cells. This protein is known for its function in facilitating antigen presentation enabling the immune response. Additionally, Professor Shachar's lab has previously shown that CD74 serves as a survival receptor on cells of the immune system, and that its stimulation by its natural ligand -migration inhibitory factor (MIF)- prevents apoptosis (self destruction) of these cells. It was shown that CD74 is markedly expressed on numerous tumors - hematologic as well as epithelial, and can serve as a prognostic marker. CD74's expression and function on colon intestinal epithelial cells is controversial.

Down the silk road of the future

The Science paper notes that the development of silk hydrogels, films, fibers and sponges is making possible advances in photonics and optics, nanotechnology, electronics, adhesives and microfluidics, as well as engineering of bone and ligaments. Because silk fiber formation does not rely on complex or toxic chemistries, such materials are biologically and environmentally friendly, even able to integrate with living systems.
