Swedish study opens new potential for combating resistant bacteria

Neisseria meningitidis, the meningococcus, is a bacterium that can cause diseases with high fatality rates, and there has therefore been considerable concern that, like other bacteria, it might become resistant to antibiotics. But now a study from örebro University and örebro University Hospital in Sweden shows that there has not been any increase in resistant meningococci in Sweden over the last 15 years. According to researcher Sara Thulin Hedberg, the reason for this may be that it is not especially advantageous for bacteria to develop resistance.

Annelie Wendeberg presents protocol for identification of environmental microbes

Metagenomics, the study of DNA isolated from samples of naturally occurring microbial populations, is rapidly growing. Improvements to cloning and sequencing techniques are allowing researchers to study microorganisms in environmental samples, and new knowledge of species interactions and community dynamics is emerging.

Scientists determine how RNAi, a biological response to RNA, can regulate gene expression

A team of scientists at Cold Spring Harbor Laboratory (CSHL) has determined a hierarchical set of criteria that explain how the molecular precursors of gene-regulating small RNAs are sorted by the cellular machinery.

Vitamin C reverses accelerated aging due to Werner's syndrome

A new research discovery published in the January 2010 print issue of the FASEB Journal suggests that treatments for disorders that cause accelerated aging, particularly Werner's syndrome, might come straight from the family medicine chest. In the research report, a team of Canadian scientists show that vitamin C stops and even reverses accelerated aging in a mouse model of Werner's syndrome, but the discovery may also be applicable to other progeroid syndromes.

Protein interaction linked to AMD

Researchers at University College London say they have gleaned a key insight into the molecular beginnings of age-related macular degeneration, the No. 1 cause of vision loss in the elderly, by determining how two key proteins interact to naturally prevent the onset of the condition.

Closer to the root cause of diabetes

A new research discovery published online in the FASEB Journal (http://www.fasebj.org) may change the perception and treatment of diabetes. That's because scientists have moved closer toward correcting the root cause of the disease rather than managing its symptoms. Specifically researchers identified a protein (G6PD protein) and its antioxidant product (NAPDH) that both prevent the death and promote the growth of cells which produce and release insulin in the pancreas (beta cells).

Study identifies novel factor that causes Alzheimer's disease

Inheritance of an extra copy of the gene- β -amyloid precursor protein, APP, in individuals with Down syndrome leads to the inevitable development of early onset Alzheimer's disease, known to be linked to the deposition of Amyloid β peptide or Aβ in the brain.

Transcription factor promotes stem cell proliferation to repair tissue damage

The master regulator of muscle differentiation, MyoD, functions early in myogenesis to help stem cells proliferate in response to muscle injury, according to researchers at Case Western Reserve University. The study appears online Jan. 4 in the Journal of Cell Biology (www.jcb.org).

Vienna scientists develop new technique for producing H1N1 vaccines

Scientists in Vienna have developed a new technique for producing vaccines for H1N1, 'swine flu', based on insect cells. The research, published today in the Biotechnology Journal, reveals how influenza vaccines can be produced faster than through the traditional method of egg-based production, revealing a new strategy for the fight against influenza pandemics.
