Discovery of mechanism that protects somatic cells against the behaviour of germ cells

An IRB Barcelona research team discovers the mechanism that favors the correct separation of germ cells -- future ovules and sperm -- from the rest of the cells during embryonic development

Discovery of unique 'DNA signature' in human sperm - unlocks egg's fertility

Drs David Miller and David Iles from the University of Leeds, in collaboration with Dr Martin Brinkworth at the University of Bradford, have found that sperm writes a DNA signature that can only be recognised by an egg from the same species. This enables fertilisation and may even explain how a species develops its own unique genetic identity.

Discovery of novel tumor suppressor

La Jolla Institute for Allergy & Immunology researchers studying an enzyme believed to play a role in allergy onset, instead have discovered its previously unknown role as a tumor suppressor that may be important in myeloproliferative diseases and some types of lymphoma and leukemia. Myeloproliferative diseases are a group of disorders characterized by an overproduction of blood cells by the bone marrow and include chronic myeloid leukemia. Lymphoma and leukemia are cancers of the blood.

Selective method kills metastatic melanoma cells

An international team of researchers has identified a new method for selectively killing metastatic melanoma cells, which may lead to new areas for drug development in melanoma - a cancer that is highly resistant to current treatment strategies.

Research points to new targets for melanoma

Recent research has uncovered an unexpected vulnerability in deadly melanoma cells that, when exploited, can cause the cancer cells to turn against themselves.

Heavy consumption of beer and spirits to 6 different cancers

Heavy drinkers of beer and spirits face a much higher risk of developing cancer than the population at large, says a group of Montreal epidemiologists and cancer researchers. Their findings show that people in the highest consumption category increased their risk of developing oesophageal cancer sevenfold, colon cancer by 80% and even lung cancer by 50%.

Lasers and nanotubes offer potential future cancer treatments

By injecting man-made, microscopic tubes into tumors and heating them with a quick, 30-second zap of a laser, scientists have discovered a way to effectively kill kidney tumors in nearly 80 percent of mice. Researchers say that the finding suggests a potential future cancer treatment for humans.

Neural correlates of impaired cognitive-behavioral flexibility in anorexia nervosa

Anorexic patients drastically reduce food intake and are often not capable of changing their behavior. This can lead to life-threatening weight loss. Using MRI technology, scientists at Heidelberg University Hospital have discovered for the first time processes in brain metabolism that explain this disturbed eating behavior.

Sleep heart health study

A study in the Aug. 1 issue of the journal Sleep indicates that self-reported worsening in initiating and maintaining sleep over a five-year period was significantly associated with poorer mental quality of life, and increasing daytime sleepiness symptoms were associated with both poorer physical and mental quality of life.

Success of GERD therapy hinges on medication type and physician bedside manner

Patient satisfaction with their medications and the quality of interactions with their doctor reflect the success of gastroesophageal reflux disease (GERD) therapy, according to a new study in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association (AGA) Institute.

Anti-growth factor drugs raise hope and concern for treatment of children's eye diseases

A new class of antibody drugs may provide a powerful new tool for the treatment of eye diseases in children, but specialists need to be alert for the possibility of serious side effects, according to an editorial in the August Journal of AAPOS (American Association for Pediatric Ophthalmology and Strabismus), published by Elsevier.

Research may bring powerful new test for inflammatory lung diseases

Chronic inflammatory lung diseases like chronic bronchitis and emphysema are a major global health problem, and the fourth leading cause of death and disability in developed countries, with smoking accounting for 90% of the risk for developing them.

Race/ethnicity, income and education associated with sugar consumption

The intake of added sugars in the United States is excessive, estimated by the US Department of Agriculture in 1999-2002 as 17% of calories a day. Consuming foods with added sugars displaces nutrient-dense foods in the diet.

U.S. spending on alternative therapies has increased 25 percent in last decade

"While Americans may complain about the high cost of health care, they're still willing to shell out roughly $34 billion a year out-of-pocket on alternative therapies that aren't covered by insurance, a new study shows," USA Today reports.

Common food additive lecithin may help control blood lipids and reduce disease risk

Scientists at Washington University School of Medicine in St. Louis have identified a substance in the liver that helps process fat and glucose. That substance is a component of the common food additive lecithin, and researchers speculate it may one day be possible to use lecithin products to control blood lipids and reduce risk for diabetes, hypertension or cardiovascular disease using treatments delivered in food rather than medication.

Heat shock proteins provide protection against cataracts

The human eye lens consists of a highly concentrated mix of several proteins. Protective proteins prevent these proteins from aggregating and clumping. If this protective function fails, the lens blurs and the patient develops cataracts. Two research groups at the Department of Chemistry of the Technische Universitaet Muenchen (TUM) have succeeded in explaining the molecular architecture of this kind of protective protein.

Discovery of genetic link to age-related cataracts

Bing-Cheng Wang, Ph.D., Case Western Reserve University School of Medicine professor of pharmacology and senior staff scientist at MetroHealth Medical Center, and Sudha K. Iyengar, Ph.D. professor of genetic and molecular epidemiology at Case Western Reserve University School of Medicine, have discovered the first gene associated with the formation of age-related cataracts, a leading causes of blindness.

Mortality rates higher in hepatitis C virus carriers

Hepatitis C virus (HCV) is a blood-borne disease that causes inflammation of the liver and to which there is currently no vaccine available. The World Health Organization (WHO) estimates that 3% of the world's population, approximately 170 million people, are infected with HCV and it is a leading cause of liver cirrhosis, end stage liver disease, hepatocellular carcinoma (HCC) and liver transplantation.

Risk factors of disordered eating in overweight youth identified

University of Minnesota Project Eating Among Teens (EAT) researchers have identified factors that may increase overweight adolescents' risk of engaging in extreme weight control behaviors such as self-induced vomiting, the use of diet pills, laxatives, and diuretics, as well as binge eating.

New nano-gene therapy technique could fight late-stage tumors

Tiny particles carrying a killer gene can effectively suppress ovarian tumor growth in mice, according to a team of researchers from MIT and the Lankenau Institute.
