Research shows no link between CCSVI and development of multiple sclerosis

Two important new studies challenge the controversial hypothesis that venous congestion—chronic cerebrospinal venous insufficiency (CCSVI)—contributes to the development of multiple sclerosis (MS). This theory has resulted in many MS patients receiving experimental endovascular angioplasty, a treatment for MS unproven by clinical trials.

Scientists identify genetic basis for prostate cancer susceptibility in non-European population

A genome-wide study on Japanese subjects has identified 5 new genetic variations associated with prostate cancer and revealed differences and similarities between Europeans and Asians in susceptibility to the disease. Reported in Nature Genetics, the findings offer a first-ever glimpse of the genetic basis for prostate cancer susceptibility in a non-European population.

Scientists identify way to regulate uncontrolled growth of blood vessels

Researchers at the University of California, San Diego School of Medicine have identified a new way to regulate the uncontrolled growth of blood vessels, a major problem in a broad range of diseases and conditions.

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.

Processed meats may increase risk of developing bladder cancer: Research

A new study suggests that consuming specific compounds in meat related to processing methods may be associated with an increased risk of developing bladder cancer. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings may be relevant for understanding the role of dietary exposures in cancer risk.

Abnormal sleep duration adversely affects cardiovascular health

A study in the Aug. 1 issue of the journal Sleep suggests that regularly sleeping for more or less than seven hours per day is associated with an increased risk of cardiovascular disease.

Scientists discover technique for more controlled lab experiments on cellular mechanobiology

Bioengineers at the University of Pennsylvania have created a system to control the flexibility of the substrate surfaces on which cells are grown without changing the surface properties, providing a technique for more controlled lab experiments on cellular mechanobiology, an important step in the scientific effort to understand how cells sense and respond to mechanical forces in their environment.

Adequate recovery sleep duration important for coping with effects of chronic sleep restriction on the brain

A study in the Aug. 1 issue of the journal Sleep suggests that a dose of extra sleep on the weekend may be good medicine for adults who repeatedly stay up too late or wake up too early during the workweek. However, even a night of 10 hours in bed may not be enough to cure the negative effects of chronic sleep restriction.

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.

Researchers identify new genetic route to treat epilepsy

New research points to a genetic route to understanding and treating epilepsy. Timothy Jegla, an assistant professor of biology at Penn State University, has identified an ancient gene family that plays a role in regulating the excitability of nerves within the brain.

Australian scientists uncover the secrets behind one of nature’s most extraordinary biological machines

Scientists from the Victor Chang Cardiac Research Institute (VCCRI), Sydney, have discovered the secrets behind the tiny motors in bacteria that allow them to swim rapidly towards nutrients and away from toxins, which is crucial to the spread of bacterial infection. These motors can rotate at up to 100,000 revolutions per minute, yet can switch directions in milliseconds.

Body’s natural cell suicide program may trigger tumor development: Study

Cancer research springs a surprise. Researchers at Walter and Eliza Hall Institute in Melbourne have found that programmed cell death (apoptosis) or cell suicide plays a role in tumor development. This process is an important phenomenon in our body as it helps remove damaged cells. Now apoptosis has been found to be protective against cancer formation and autoimmune diseases.

Reality TV shows take full advantage, tout teen happiness: Research

Teenage years have long been linked with a heightened concern with appearance. Some reality TV shows take full advantage and tout happiness as just a nip/tuck away. A Rutgers-Camden psychologist has found that teens fond of these kinds of programs are more likely to join the millions who go under the knife each year. For bodies - and minds - still in development, these drastic decisions could have implications way after prom.

Study uses text messages to increase medication compliance in adolescent diabetes patients

Jennifer Dyer, MD, MPH, an endocrinologist at Nationwide Children's Hospital, has developed and completed a pilot study that uses weekly, customized text messages to remind adolescent diabetes patients about their personal treatment activities. At the conclusion of the study, Dr. Dyer found an increase in overall treatment adherence and improved blood glucose levels.

Study implicates Fritz's role in human genetic disorders

Mutations in a gene known as "Fritz" may be responsible for causing human genetic disorders such as Bardet-Biedl syndrome, University of Texas at Austin developmental biologist John Wallingford and Duke University human geneticist and cell biologist Nicholas Katsanis have found.

Pathwork Diagnostics enters into research collaboration with Novartis

Pathwork Diagnostics Inc., a molecular diagnostics company focused on oncology, today announced that it has entered into a research collaboration with Novartis. The parties intend to discover clinically meaningful biomarker signatures that can serve as the basis for diagnostics across a range of cancer types. Under the terms of the agreement, both parties have rights to develop and commercialize the diagnostic products. Financial terms were not disclosed.

Oral contraceptives, HRT may protect women against formation, rupture of brain aneurysms: Study

Results from a new study suggest that oral contraceptives and hormone replacement therapy may yield additional benefit of protecting against the formation and rupture of brain aneurysms in women. The findings from this first-of-its-kind study by a neurointerventional expert from Rush University Medical Center were presented at the Society of Neurointerventional Surgery 7th annual meeting.

Research establishes bases of possible future pharmaceutical drugs to combat AIDS virus

The doors are closing on the AIDS virus. The scientific community continues to strive to find the formula that will halt the advance of one of the viruses that has sparked most scientific interest over recent years. A study by the Consejo Superior de Investigaciones Cient-ficas (CSIC) and led by Mr F-lix Go-i, director of the Biophysics Unit at the CSIC-University of the Basque Country Mixed Centre, has developed a method of attack against the AIDS virus The method involves creating a prevention system, i.e. an 'armour' in the cells that are likely to be infected and thus impede, de facto, the virus from accessing them and starting to act on their immunological system.

Exposure of mBM-MSCs to VPA increases hepatic differentiation

Recent studies suggest that MSCs possess a greater differentiation potential than once thought and several hepatic differentiation protocols from bone marrow cells have been established. However, the incidence of bone marrow-derived hepatocytes was low. Moreover, a long culture period is needed in most cases.

Mental-health treatment could reduce pain in osteoarthritis patients: Study

How much pain osteoarthritis sufferers feel is directly related to their mental health, a new study by researchers at UC Davis School of Medicine has found. In the study, people with better mental health felt less pain, and people with worse mental health felt more.
