Influenza :: Pandemic influenza vaccine Focetria approved
Approval of Focetria, an immune enhancing pandemic influenza vaccine, would allow for more rapid response in the event of influenza pandemic.
Patients :: Doubts over studies raise serious implications for patients
Doubts over three influential head injury studies mean that patients are receiving treatment that may be unsound, warn doctors in this week?s BMJ.
RNA :: Killing the messenger RNA — But which one?
Tiny molecules called microRNAs, only 19 to 21 nucleotides in length, are able to effectively silence sometimes large sets of genes. They do this by specifically binding to and neutralizing another form of RNA called messenger RNA, responsible for conveying the information from genes to the cellular machinery that uses that information to create proteins, the building blocks of the body.
Genome :: Opening and closing the genome
At any given time, most of the roughly 30,000 genes that constitute the human genome are inactive, or repressed, closed to the cellular machinery that transcribes genes into the proteins of the body.
Alcoholism :: Greater deficits in emotional facial expression can indicate more severe alcoholism
Recognition of emotional facial expressions (EFEs) is a key form of non-verbal communication that is lacking among alcoholics. New findings show continuing EFE decoding deficits among alcoholics even after three months of abstinence.
Meningitis :: Scientists identify specific enzymes that make meningitis hard to fight
Two enzymes in meningitis bacteria which prevent the body from successfully fighting off the disease, and make the infection extremelyvirulent, have been identified in new research published today.
Cancer :: CSHL research ties harmless viruses to cancer
Research led by Cold Spring Harbor Laboratory (CSHL) may link viruses that have been considered harmless to chromosomal instability (CIN) and cancer.
Coeliac Disease :: Possible relationship between myopathies and coeliac disease
Inflammatory myopathies are immunological diseases that lead to inflammations in muscular tissue. As of yet, little is known about the cause of these myopathies, but it is believed to be an abnormal immune response by our bodies.
Stem Cell :: Liposuctioned fat stem cells to repair bodies
Expanding waistlines, unsightly bulges: people will gladly remove excess body fat to improve their looks. But unwanted fat also contains stem cells with the potential to repair defects and heal injuries in the body.
