New guidelines, released by the Centers for Disease Control and Prevention (CDC) and the Healthcare Infection Control Practices Advisory Committee (HICPAC) outline steps to eliminate bloodstream infections in patients with intravenous catheters, which are among the most deadly and costly healthcare-associated infections (HAIs).

LA JOLLA, CA—When cells find themselves in a tight spot, the cell cycle regulator p21 halts the cell cycle, buying cells time to repair the damage, or if all else fails, to initiate programmed cell death. In contrast to other stress-induced genes, which dispense with the regular transcriptional entourage, p21Cip1 still requires SKIP, a transcription elongation factor that also helps with the editing of transcripts, to be expressed, found researchers at the Salk Institute for Biological Studies.
BUFFALO, N.Y. -- A low dose of insulin has been found to suppress the expression in the blood of four precursor proteins involved in the pathogenesis of Alzheimer's disease, according to new clinical research by University at Buffalo endocrinologists. The research, published in March online in the Journal of Clinical Endocrinology and Metabolism, suggests that insulin could have a powerful, new role to play in fighting Alzheimer's disease.
MAYWOOD, Ill. -- An award-winning Loyola University Health System study includes some unexpected findings about the immune systems of smoke-inhalation patients.
Contrary to expectations, patients who died from their injuries had lower inflammatory responses in their lungs than patients who survived.
"Perhaps a better understanding of this early pulmonary immune dysfunction will allow for therapies that further improve outcomes in burn care," researchers reported.
Berlin, Germany, Friday 01 April 2011: Early data from phase I trials of an HCV vaccine presented today at the International Liver CongressTM show encouraging results, with high immunogenicity and good safety profile.1,2
A new study presented today at the International Liver CongressTM shows a novel pathway where activated natural killer (NK) cells expressing death ligands may excessively down-modulate the antiviral immune response in chronic HBV patients.1
Blocking the TNF-related apoptosis-inducing ligand (TRAIL) pathway partially reconstitutes HBV-specific T cells, suggesting that these cells are vulnerable to NK cell-mediated apoptosis through this death ligand pathway.

Some may think that the mosquito and the house fly are worlds apart when it comes to common ancestry but new research published this week by an international team of scientists puts them much closer together in evolutionary history.According to a paper published in the Proceedings of the National Academy of Sciences of the USA, the mosquito branched off the same evolutionary tree as the house fly around 220 million years ago.
Berlin, Germany, Friday 1st April 2011: Highly anticipated data from a number of clinical trials presented for the first time at the International Liver CongressTM confirmed that a range of new proteases inhibitors will help treat patients who have previously failed therapy for the treatment of chronic hepatitis C.1,2,3,4,5
Obsessive-compulsive disorder is often diagnosed too late in children and adolescents. In the current issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2011; 108: 173-79), Susanne Walitza and her colleagues point out that appropriate early recognition and treatment can positively affect the course of the disease.
The dormouse in Alice in Wonderland was well advised to stay asleep – especially as doing so did not prevent it from taking a full part in the tea-time conversation. Dormice in Europe spend about eight months of the year asleep and are extremely safe during this extended period, with almost all of them surviving the winter. This result comes from a study of dormouse survival rates in Austria, the Czech Republic, England, Germany and Italy.
A potential new experimental diagnostic test able to quickly distinguish individuals with active tuberculosis (TB) from those with latent TB infection has been developed. If the preliminary results of the study will be confirmed in a larger population sample, the new diagnostic system could allow more effective strategies to control the spread of the re-emerging pathology.
New research from the University of Cincinnati provides food for thought.
The research examined how short-term and long-term hunger affected mate selection and aggression in female wolf spiders (Schizocosa ocreata) commonly found in the eastern United States and Canada. These female spiders are potentially aggressive and cannibalistic when approached by a courting male.
