Nanowire sensors show huge potential for point-of-care disease detection

Yale scientists have created nanowire sensors coupled with simple microprocessor electronics that are both sensitive and specific enough to be used for point-of-care (POC) disease detection, according to a report in Nano Letters.

Ultra-sensitive nanoprobes help tackle MRSA

This week Nature Nanotechnology journal (October 12th) reveals how scientists from the London Centre for Nanotechnology (LCN) at University College London are using a novel nanomechanical approach to investigate the workings of vancomycin, one of the few antibiotics that can be used to combat increasingly resistant infections such as methicillin-resistant Staphylococcus aureus (MRSA).

Tuberculosis vaccine a step closer

Researchers at Aberystwyth University, following a number of years of investment by the Biotechnology and Biological Sciences Research Council (BBSRC), have licensed ground-breaking research to a non-profit product development partnership working to develop new, more effective vaccines against Tuberculosis (TB). This development will give hope that significantly better prevention and treatment of TB will be available within the next few years.

Reason for body's response to borrelia discovered

Inside a cell it is so crowded that a certain protein from borrelia winds up being crunched. From having been like an oblong rugby football, it gets bent and then collapses into a lump. At this point a previously hidden part appears, known to trigger the formation of antibodies. This explains how Borrelia can be diagnosed, a process that was previously unknown.

FDA approves Rapaflo for treatment of symptoms due to benign prostatic hyperplasia

The U.S. Food and Drug Administration today approved Rapaflo (silodosin) capsules for the treatment of symptoms due to benign prostatic hyperplasia (BPH), a condition also known as an enlarged prostate.

Tracking down the cause of Mad Cow disease - first synthetic prion protein with an anchor

The cause of diseases such as BSE in cattle and Creutzfeld-Jakob disease in humans is a prion protein. This protein attaches to cell membranes by way of an anchor made of sugar and lipid components (a glycosylphosphatidylinositol, GPI) anchor. The anchoring of the prions seems to have a strong influence on the transformation of the normal form of the protein into its pathogenic form, which causes scrapie and mad cow disease.

Helicobacter pylori may help prevent adenocarcinoma, esophageal cancers

Some bacteria may help protect against the development of a type of esophageal cancer, known as adenocarcinoma, according to a new review of the medical literature. These bacteria, which are called Helicobacter pylori, live in the stomachs of humans.

Disinfectants can make bacteria resistant to treatment

Chemicals used in the environment to kill bacteria could be making them stronger, according to a paper published in the October issue of the journal Microbiology. Low levels of these chemicals, called biocides, can make the potentially lethal bacterium Staphylococcus aureus remove toxic chemicals from the cell even more efficiently, potentially making it resistant to being killed by some antibiotics.

New vaccines may not reduce tuberculosis incidence

Despite the potential of new vaccines to prevent TB, new research shows that the removal of one strain of TB can allow a previously suppressed strain to succeed. Consequently, a vaccination program could result in the proliferation of strains more likely to be, or become, drug resistant, and could even result in an increased prevalence of the disease.

DNA of good bacteria drives intestinal response to infection

A new study shows that the DNA of so-called "good bacteria" that normally live in the intestines may help defend the body against infection.
