Antioxidants may cause fertility problems in females

Antioxidants are sold over the counter everywhere. They're added to food, drink and face cream. But according to Prof. Nava Dekel of the Biological Regulation Department, we still don't have a complete understanding of how they act in our bodies. New research by Dekel and her team, recently published in the Proceedings of the National Academy of Sciences USA (PNAS), has revealed a possible unexpected side effect of antioxidants: They might cause fertility problems in females.

Cells that give rise to neurons maintain high levels of ROS

For years, the majority of research on reactive oxygen species (ROS) - ions or very small molecules that include free radicals - has focused on how they damage cell structure and their potential link to stroke, cardiovascular disease and other illnesses.

Researchers demonstrate that monensin antibiotic prevents prostate cancer cell growth

Researchers from VTT Technical Research Centre of Finland and the University of Turku have demonstrated that an antibiotic called "monensin" prevents the growth of prostate cancer cells. Monensin is used in the meat and dairy industry, for example.

Research highlighting treatment for pediatric SCD, malaria presented at ASH 2010

Red blood cells have the very important role of carrying oxygen from the lungs to the rest of the body; therefore, disorders that affect RBCs can have a significant impact on quality of life. Sickle cell disease and malaria are two common RBC diseases that affect a significant portion of the U.S. and global populations. Sickle cell disease, a genetic blood disorder that causes deformed and dysfunctional red blood cells, affects an estimated 70,000 to 100,000 Americans, while malaria affects approximately 1,500 Americans annually and 190 to 311 million people worldwide.

Burn injuries in children show vitamin E depletion in fat tissues

Severe burn injuries in children have been shown to rapidly deplete the levels of vitamin E in their body's adipose, or fat tissues, a new clinical study has found.

Researchers develop new approach to treat inflammatory bowel disease

Researchers at the Georgia Institute of Technology and Emory University have developed a novel approach for delivering small bits of genetic material into the body to improve the treatment of inflammatory bowel diseases. Delivering short strands of RNA into cells has become a popular research area because of its potential therapeutic applications, but how to deliver them into targeted cells in a living organism has been an obstacle.

Low-fat diet reduces risk of heart disease

Losing weight, especially among adults who are very heavy to obese, is a good way to prevent the onset of atherosclerosis, the artery-thickening condition that leads to potentially deadly heart disease. A diet that is low in either fats or carbohydrates can help reduce weight. But which one is the more heart-healthy?

Hormone melatonin improves egg quality in IVF

Poor egg (oocyte) quality is an important cause of female infertility. Low quality eggs may have several problems, for example they may not divide properly, or they may be missing certain chromosomes. Egg quality also declines with age, and certain medical conditions, such as PolyCystic Ovary Syndrome, can lead to poor quality eggs.

Insulin may reduce life-threatening bacterial infections in intensive care patients

Treating intensive care patients who develop life-threatening bacterial infections, or septicemia, with insulin potentially could reduce their chances of succumbing to the infection, if results of a new preliminary study can be replicated in a larger study.

Synthetic derivative of Retinoic acid can induce cell death

Retinoic acid (RA), a natural derivative of vitamin A, is the basis of a number of treatments against cancer. Nevertheless, it has certain disadvantages, such as the possibility of the appearance of retinoic acid syndrome, present in 25 % of cases and which can lead to death. The development of 4-HPR, a synthetic derivative of RA, has meant a considerable advance due to its greater efficacy compared to its predecessor.

Further evidence on adverse effects of smoking on fertility

Two new studies have shed more light on how smoking may damage fertility, and give further weight to advice that mothers and fathers-to-be should stop smoking before attempting to conceive. The research is published online in the reproductive medicine journal Human Reproduction today (Wednesday 8 September).

Critical mechanistic link between mutant protein and disease pathogenesis in ALS uncovered

New research uncovers what may be a primary neuron-damaging insult that occurs in an inherited form of a devastating neurodegenerative disorder. The study, published by Cell Press in the August 26th issue of the journal Neuron, describes a critical mechanistic link between a mutant protein and disease pathogenesis in an animal model of amyotrophic lateral sclerosis (ALS).
