Scientists develop new method to identify factors that suppress cancer gene expression

Tumor suppressor genes normally control the growth of cells, but cancer can spring up when these genes are silenced by certain chemical reactions that modify chromosomes.

Study suggests causal link between HSV1 and Alzheimer's disease

Laboratories at the University of New Mexico (UNM), Brown University, and House Ear Institute (HEI) have developed a new technique to observe herpes simplex virus type 1 (HSV1) infections growing inside cells. HSV1, the cause of the common cold sore, persists in a latent form inside nerve cells.

Towards accurate simulation of whole working cells

Researchers have built a computer model of the crowded interior of a bacterial cell that - in a test of its response to sugar in its environment - accurately simulates the behavior of living cells.

Researchers develop new virus-based nerve-tracing technique

If, as Shakespeare's Juliet declared, a rose by any other name smells as sweet - to you and to me and to anyone else who sniffs it - then one might assume that our odor-sensing nerve cells are all wired in the same way. Alas, they are not, according to a new study from scientists at The Scripps Research Institute.

Top-line results from Biomoda's CyPath pilot study against lung cancer

Cancer diagnostics company Biomoda, Inc. today announced top-line results of its pilot study for lung cancer which shows highly significant evidence of CyPath's ability to discriminate between cancer and non-cancer groups based on sputum samples collected in a non-invasive manner.

Oral antioxidant formulation before medical imaging may minimize cell damage

A unique formulation of antioxidants taken orally before imaging with ionizing radiation minimizes cell damage, noted researchers at the Society of Interventional Radiology's 36th Annual Scientific Meeting in Chicago, Ill.

Study: Thyroid hormone deficiency can affect cone opsins and colour vision

Thyroid hormone controls the eye's visual pigments throughout life. What part does the thyroid gland have in vision? Thyroid hormone is crucially involved in controlling which visual pigment is produced in the cones. Previously, it was assumed that the colour sensitivity of the cones is fixed in the adult retina.

Ohio engineers invent new fluorescent nano-particle to tag molecules in biomedical tests

Engineers at Ohio State University have invented a new kind of nano-particle that shines in different colors to tag molecules in biomedical tests.

Almac, BioFocus partner to provide FLT assays

BioFocus and Almac have initiated a collaboration which will provide BioFocus customers with compound screening and profiling services using Almac's FLEXYTETM fluorescence lifetime assays.

Researchers identify new mechanism underlying MS

Multiple sclerosis is a disabling autoimmune disease in which nerve fibers are attacked by the patient's own immune system. Researchers at Ludwig-Maximilians-Universitaet in Munich have identified a new mechanism that contributes to nerve fiber damage - and shown that this damage can be reversed.

Quantum dots allow stem cell therapy monitoring for brain injury

A new technique using "quantum dots" produced through nanotechnology is a promising approach to monitoring the effects of stem cell therapies for stroke and other types of brain damage, reports the April issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

VARI, Gentel Biosciences receive U.S. Patent for new glycan detection technology

Gentel Biosciences, a leader in proteomics tools, and Van Andel Research Institute, a biomedical research institute, jointly announce today the granting of U.S. Patent 7,838,634 for a new method to profile changes in the glycosylation of proteins captured on the surface of an antibody array slide. Gentel first obtained an exclusive right to commercialize the technology in 2006.

Imaging with voltage-sensitive dye captures real-time brain dynamics

The dye incorporates in the brain cells' membrane and changes fluorescence whenever these receive or send electrical signals. Hence, high resolution camera systems allow to simultaneously capture activities of millions of nerve cells across several square millimeters across the brain.

Cell receptor recycling mechanism discovery opens up new class of therapeutic targets

Prof. Manojkumar Puthenveedu of Carnegie Mellon University studies the mechanisms by which membrane trafficking controls and co-ordinates the complex signalling pathways in the brain. Despite the fact that almost all diseases can be traced to a defect in how cells respond to signals, little is known about how signalling pathways are maintained in normal cells and the changes that occur in abnormal conditions.

Contrast agent for tumor diagnostics

X-rays are not the only way: visible and especially infrared light can also be used to image human tissue. The effectiveness of optical imaging processes can be significantly improved with suitable dyes used as contrast agents. In the journal Angewandte Chemie, a team led by Wenbin Lin at the University of North Carolina (Chapel Hill, USA) has now introduced a novel contrast agent that marks tumor cells in vitro. The dye is a phosphorescent ruthenium complex incorporated into nanoparticles of a metal–organic coordination polymer, which allows an extraordinarily high level of dye loading.
