ESRC offers new dynamics for old in UK

By 2025, the number of people in Britain over the age of 60 will outnumber those under 25. Pressure on both pensions and pensioner spending power will increase. Answers to problems//, old and new, will have to be sought. In a move to address the issues of ageing - one of the most significant aspects of change in our lives, the Economic and Social Research Council (ESRC) is highlighting...

Infections Of The Oral Cavity Can Be Treated By Photodynamic Therapy

Anti-biotic resistant bacterial and fungal infections of the oral cavity can be effectively treated by using photodynamic therapy (PDT)//, argue researchers from the University at Buffalo's School of Dental Medicine. Photodynamic therapy is commonly employed in cancer treatment. PDT is currently employed in the treatment of Kaposi's sarcoma, breast cancer (spread to the chest wall) an...

"Dynamic Energy Landscape" of enzyme in Catalysis

Complex protein molecules called enzymes catalyze specific biochemical reactions in cells. The traditional theory is that dynamic fluctuations//protein conformation or structure play a major role in enzyme catalysis. However, recent findings reveal that it is the "dynamic energy landscape" of the enzyme that directs it to a specific pathway that reduces the number and dimension of the ene...

Predicting the Dynamics of Clotting in Human Blood

University of Chicago chemists have demonstrated for the first time how to use a simple laboratory model consisting of only a few chemical reactions to predict when and where blood clotting will occur.// The scientists used microfluidics, a technique that allows them to probe blood clotting on surfaces that mimic vascular damage on the micron scale, a unit of measurement much narrower tha...

Photodynamic Therapy can Scramble the Immune System to Fight Cancer Spread

A light-triggered cancer treatment called photodynamic therapy (PDT) may be able to treat advanced cancer at the same time as targeting local tumours , according to research published in the British Journal of Cancer today (Tuesday). PDT is a relatively new way of treating cancer, still at an early stage of development and being researched in labs around the world. It uses drugs tha...

Dynamic Sonography Accurate in Diagnosing Muscle Tears

Dynamic sonography is useful in the diagnosis, management and follow-up of muscle tears and hematomas, according to a recent study conducted by researchers from Khoula Hospital in Muscat, Oman . The study consisted of 50 male soccer players ranging from 20-30 years of age with muscular trauma in the thigh and calf. Dynamic sonography of both the affected and contralateral normal par...

Study Revises Dynamin's Role in Nerve Cell Function

An unexpected finding on how nerve cells signal to one another could rewrite the textbooks on neuroscience, says a collaborative team of researchers at Weill Cornell Medical College and Yale University. Their study, published as a high-profile research article in the journal Science, suggests that a key cellular enzyme called dynamin 1 is not essential to all synaptic transmission,...

Replidyne Announces Positive Phase I Results for Topical Antibiotic REP8839

Replidyne, Inc. today announced results from three Phase I trials studying REP8839, a novel topical antibiotic that has shown potent in vitro activity against major skin pathogens including methicillin-resistant S. aureus (MRSA). The results of the Phase I trials show that topically applied REP8839 appears safe, well-tolerated and associated with low systemic exposure, or drug abso...
