More evidence needed to link symptoms like tics or behavioral problems to a strep infection

Cephalosporins three times more effective than penicillin

Pediatricians treating a child who has strep throat should reconsider the role of penicillin given that a newer class of antibiotics called cephalosporins are three times more effective, according to a study being published in the April issue of Pediatrics. The findings will spark widespread debate, because they contradict long-established guidelines from the American Academy of Pediatrics, American Heart Association,and World Health Organization.

Scientists have discovered that a non-genetic molecular process can effect cell behaviour

Genetic mutations, sudden, random and usually harmful changes to the structure of a gene, are only one factor that determines the ultimate fate of a cell. Chicago scientists have discovered that a non-genetic molecular process also can play a role, and that experimenters can influence this process in bacteria, they report in the April 1 issue of the journal Nature.

SARS virus vaccine stimulates protective immune response

An experimental vaccine prevents the SARS virus from replicating in laboratory mice, according to a new report in the April 1 issue of Nature. Scientists at the Vaccine Research Center (VRC) of the National Institute of Allergy and Infectious Diseases (NIAID), one of the National Institutes of Health, developed the vaccine. The vaccine was tested in a mouse model of SARS infection recently validated by other NIAID investigators.

Research team has found a new way to streamline gene isolation to determine their functions

A single strand of plant or animal DNA may contain tens of thousands of genes, each programmed to produce a specific protein essential for the growth or survival of the organism. The challenge for geneticists is to isolate individual genes and determine their function -- a painstaking process often requiring years of laboratory trial and error.

Natural compound in snake venom for treatment of malignant tumours

Researchers at the University of South Australia have made a major discovery using a natural compound in snake venom that shows very promising anti-cancer effects. The compound works by activating the destruction of cells which make up the blood vessels that supply nutrients to tumours, according to Associate Professor Tony Woods from UniSA’s School of Pharmaceutical, Molecular and Biomedical Sciences.

Children with sickle cell disease are living longer, dying less often from their disease

Children with sickle cell disease, an inherited red blood-cell disorder, are living longer, dying less often from their disease and contracting fewer fatal infections than ever before, researchers at UT Southwestern Medical Center at Dallas report. Their study, which will appear in the June edition of the scientific journal Blood, is the first to evaluate survival rates of children receiving the most modern treatments for sickle cell disease. It's also one of the largest published sickle cell studies to date. Researchers followed more than 700 Dallas-area children with the disease over two decades.

A debate over the origins of what is sometimes called "junk" DNA has been settled

A debate over the origins of what is sometimes called "junk" DNA has been settled by research involving scientists at the Center for Advanced Research in Biotechnology (CARB) and a collaborator, who developed rigorous proof that these mysterious sections were added to DNA "late" in the evolution of life on earth, after the formation of modern-sized genes, which contain instructions for making proteins.

Asthma study turns up new information on viral infections

Researchers know that viral infections can exacerbate asthma and, in turn, make people with the condition more sensitive to environmental exposures such as endotoxin. But how viral infections contribute to this sensitivity in airway cells has not been clear. A recent study led by investigators from the University of Iowa Roy J. and Lucille A. Carver College of Medicine and the Veterans Affairs Medical Center (VAMC) in Iowa City shows, for the first time, that viral infections may increase environmental sensitivity in lung epithelial (surface) cells by changing expression of receptors on those cells.

Scientists discover a method to detect trace levels of swine antibiotics in the groundwater.

Scientists from the Department of Soil, Water, & Climate at University of Minnesota have developed a simple method to quantify two types of antibiotics in animal manures, and surface and ground waters. Chlortetracycline and tylosin antibiotics are commonly used for growth promotion in swine production.

British company to launch "super bug tester" into UK hospitals

MRSA is the first test to be developed from Acolyte’s BacLite® testing platform. BacLite reduces the time for identifying both the type of bacteria and, more importantly, the antibiotic sensitivity of the bacteria from the current 3-4 day standard to just 2-5 hours. This time advantage will mean clinicians will be able to treat, much more effectively, serious bacterial infections and prevent potentially fatal complications, such as sepsis and septic shock, from developing.

EU gives 32 million Euro for vaccines to stop tuberculosis

The European Commission today launched the largest-ever collaborative tuberculosis (TB) initiative for World TB-day, March 24. Fifty-two research teams from academia and industry from 15 European and African countries are joining forces with the European Commission to help eradicate TB. Globally, TB kills 2 million people a year, with one-third of the world's population currently infected with the bacillus, Mycobacterium tuberculosis (Mtb). While most cases and deaths occur in developing countries, resistant Mtb strains are mainly found among the poorest people in developed countries, as incomplete treatment increases drug resistance. The European Union is confronting the re-emerging threat of TB by investing €32 million in two overlapping research projects. This cash will be used in an accelerated effort to develop new, effective vaccines to fight TB.
