Neuronal receptor response may help explain Alzheimer’s memory loss

Based on laboratory research, scientists at Georgetown University Medical Center have a new theory as to why people with Alzheimer's disease have trouble performing even the simplest memory tasks, such as remembering a family member’s name. more

Anti-HIV drug has potential to prevent transmission in women

A new study from infectious disease researchers at The Miriam Hospital and Brown Medical School finds that a drug already given orally to treat HIV is also safe when applied as a vaginal microbicide gel. Microbicides are designed to prevent the sexual transmission of HIV and other sexually transmitted diseases and may be formulated as vaginal gels, foams, creams, or suppositories. more  

Metabolic acidosis associated with an increased mortality rate

Critically ill patients with metabolic acidosis are twice as likely to die as patients who do not have metabolic acidosis. A study published today in the journal Critical Care shows that the mortality rate among patients with metabolic acidosis is highest for patients with lactic acidosis – abnormally acidic blood pH due to an excess of lactate - but it is also considerable for patients with strong ion gap (SIG) acidosis – acidosis due to an excess of unidentified ions. Both lactate and SIG should be carefully monitored in intensive care units (ICUs). more

The smoking gun: Elastin fragments drive emphysema 

Pulmonary emphysema is caused primarily by cigarette smoking, and the underlying cellular mechanisms are thought to involve smoke-induced activation of tissue degrading enzymes known as proteases. Elastases are proteases that specifically degrade the structural protein elastin and include enzymes such as MMP-12 (matrix metalloproteinase –12, also called macrophage metalloelastase), which is secreted by inflammatory cells called macrophages. more

Climate change may affect length of respiratory infection season
