Cleavage stage embryo with aneuploidy can undergo genetic normalisation process

Professor William G. Kearns told the annual meeting of the European Society of Human Reproduction and Embryology that a three-day-old embryo with an incorrect number of chromosomes was capable of undergoing "a dynamic process of genetic normalisation" so that by day five, when it had developed to the blastocyst stage, it had become euploid, with the correct number of chromosomes.

LCMC finds 9.6% of lung cancer patients with ALK rearrangement

ALK rearrangement has been found in 9.6% of lung cancer patients tested in the Lung Cancer Mutation Consortium, and MET amplification in another 4.1%, reflecting how many patients might benefit from targeted therapies such as crizotinib, according to research presented at the 14th World Conference on Lung Cancer in Amsterdam, hosted by the International Association for the Study of Lung Cancer.

Adipose tissue might serve as target for treating obesity-related disorders

Researchers at Boston University School of Medicine (BUSM) and Boston Medical Center (BMC) have shown that the quality - not just the quantity - of adipose, or fat, tissue is a significant contributing factor in the development of inflammation and vascular disease in obese individuals.

Study helps explain why fatty foods are complicit in weight gain

Recent studies have revealed potato chips and french fries to be the worst contributors to weight gain - and with good reason. Have you ever wondered why you can't eat just one chip or a single fry? It's not just the carbohydrates at fault.

Zebrafish study uncovers new information about hepatocellular carcinoma

Hepatocellular carcinoma, the most common type of liver cancer, is a leading cause of cancer-related deaths worldwide. Although there are several treatment options available, they are largely unsuccessful because the disease is so poorly understood. Clinical studies of patients with HCC, combined with studies using mice and other animal models, have provided some clues, but many questions about how to diagnose and treat this deadly form of cancer remain.

Research addresses chromosomal imbalance in embryos

Joint research between the University of Kent's Professor Darren Griffin, London Bridge Fertility Centre and BlueGnome Ltd has addressed chromosomal imbalance in embryos, a condition that is currently the major cause of pregnancy loss in IVF.

New insight into oocyte chromosome abnormalities

Ovarian stimulation undertaken by women of advanced maternal age receiving fertility treatment may be disrupting the normal pattern of meiosis - a critical process of chromosome duplication followed by two specialised cell divisions in the production of oocytes and sperm - and leading to abnormalities of chromosome copy numbers that result in IVF failure, pregnancy loss or, more rarely, the birth of affected children with conditions such as Down's syndrome, which is caused by the inheritance of three copies of chromosome 21.

Simple blood test for melanoma-inhibitory activity could detect neurofibromas

Neurofibromatosis (NF1) is a genetic condition which affects one in every 3,000 people. The severity of symptoms can range from benign 'café au lait' patches on the skin, through small tumors under the skin and deep plexiform neurofibromas, to malignant tumors of the nerve sheath.

Researchers use clever technique to look at in vivo virus-bacterium interactions

Viruses are the most abundant parasites on Earth. Well known viruses, such as the flu virus, attack human hosts, while viruses such as the tobacco mosaic virus infect plant hosts.

Scientists use statistical approach to assess order of genetic abnormalities in cancers

Zeroing in on the early cell mutations that enable a cancer to grow is one of the best ways to find a personalized therapy to stop it. Scientists were able to use a statistical approach for the first time to map out the order in which these abnormalities form to analyze the pattern of DNA changes in advanced skin and ovarian tumors.

Beetroot juice effective for simulated competition environment

Winning margins in the Tour de France can be tight - last year just 39 seconds separated the top two riders after more than 90 hours in the saddle. When every second counts, riders do everything possible to gain a competitive advantage - from using aerodynamic carbon fibre bikes to the very latest in sports nutrition.

Johns Hopkins team reconstitutes single stem cells' family tree

A Johns Hopkins team has discovered in young adult mice that a lone brain stem cell is capable not only of replacing itself and giving rise to specialized neurons and glia - important types of brain cells - but also of taking a wholly unexpected path: generating two new brain stem cells.
