Researchers explain how nerve cells transmit electrical signals

Billions of brain cells are communicating at any given moment. Like an organic supercomputer they keep everything going, from breathing to solving riddles, and "programming errors" can lead to serious conditions such as schizophrenia, Parkinson's disease and attention-deficit hyperactivity disorder.

Scientific advances in glycomics

The glycome, encompassing all of the complex sugars produced by an organism, is comprised of multiple families of molecules whose function in the human body is often determined by the structure, composition, and placement of the attached sugars, as explored in a comprehensive look at the field of glycomics in a group of key articles in OMICS: A Journal of Integrative Biology, a peer-reviewed journal published by Mary Ann Liebert, Inc. (www.liebertpub.com). The relevant articles are available free online at www.liebertpub.com/omi.

Scientists discover SNP association with primary open-angle glaucoma risk

Scientists at deCODE genetics and academic colleagues from Iceland, China, Sweden, the UK and Australia today report the discovery of the most important single-letter variation (SNP) in the sequence of the human genome yet associated with risk of primary open-angle glaucoma. This is the most common form of glaucoma and a major cause of blindness worldwide.

Researchers demonstrate how insulin prepares cells for glucose uptake

Using high-resolution microscopy, researchers at the National Institutes of Health have shown how insulin prompts fat cells to take in glucose in a rat model. The findings were reported in the Sept. 8 issue of the journal Cell Metabolism.

Researchers reveal surface protein alteration mechanism of mycoplasma bacteria

Pathogenic bacteria have evolved a variety of mechanisms to avoid being killed by the immune systems of the humans and animals they invade. Among the most sophisticated is that practised by mycoplasmas, which regularly change their surface proteins to confuse the immune system. Recent work in the group of Renate Rosengarten and Rohini Chopra-Dewasthaly at the University of Veterinary Medicine, Vienna has revealed surprising new details of the way they do so and at the same time raised important evolutionary questions.

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.
