Obstructive sleep apnea starts from the first year of life

Obstructive sleep apnea (OSA) in very young children may cause some of the adverse cardiovascular health consequences seen in older children and adults with the condition, according to researchers in Israel, who will present their findings at the American Thoracic Society's 2008 International Conference in Toronto on Wednesday, May 21.

Nanoworms target tumors

By linking strings of spherical iron oxide nanoparticles and coating the resulting construct with a biocompatible polymer, a multi-institutional research team has created "nanoworms" that can better target tumors and produce stronger magnetic resonance imaging (MRI) signals than their component nanoparticles. The nanoworms also appear to be a promising vehicle for carrying anticancer drugs into tumors. The researchers published their work in the journal Advanced Materials.

Model shows how mutation tips biochemistry to cause Alzheimer's

Your fate can be determined by tiny events. Imagine you live in the city and you walk everywhere to get exercise - you are healthy and not afraid of getting mugged. You almost never eat breakfast so you don't stop at the donut shop on the way to work, until one day the manager replaces the girl at the counter with her pretty red-haired younger sister. This seemingly unimportant change in your world is just enough to overcome your ability to resist high-fat temptation. A million donuts later, your cholesterol level surges and then your heart gives out. Curse you, little red-haired girl!

PolyMedix receives clearance to initiate phase I clinical study of novel systemic antibiotic compound

PolyMedix, Inc. has received a notice of no objection from Health Canada for the Company's Clinical Trial Application ("CTA") for its defensin mimetic antibiotic compound, PMX-30063. This notice of no objection allows for the initiation of human clinical studies in Canada. PMX-30063 is the first defensin mimetic antibiotic compound cleared to enter human clinical trials for systemic use, representing an entirely new class of antibiotic drugs.

Nanoworms developed to target tumors

Scientists at UC San Diego, UC Santa Barbara and MIT have developed nanometer-sized "nanoworms" that can cruise through the bloodstream without significant interference from the body's immune defense system and-like tiny anti-cancer missiles-home in on tumors.

Enkephalin pathway shows potential as new target for Alzheimer's

Alzheimer's disease (AD) is an incurable disease that is increasing in prevalence and will increase even more rapidly as the Baby Boom generation enters the age of highest risk. The available AD drugs are only partially effective in some patients. New strategies are urgently needed.

Better understanding of immune response to HIV infection

The "exhaustion" of immune cells that target HIV appears to result from chronic exposure to the virus, specifically exposure to the particular protein segments targeted by the pathogen-killing HIV-specific CD8 T cells.

Alzheimer's and diabetes link

Diabetic individuals have a significantly higher risk of developing Alzheimer's disease but the molecular connection between the two remains unexplained. Now, researchers at the Salk Institute for Biological Studies identified the probable molecular basis for the diabetes - Alzheimer's interaction.

Pin1 is beneficial in Alzheimer's disease, detrimental to some forms of dementia

The most common form of dementia, Alzheimer's disease, and a relatively rare hereditary form of dementia, frontotemporal dementia with parkinsonism-17, share a common pathology: Both are the result of an overaccumulation of tau proteins, which form tangled lesions in the brain's neurons and eventually lead to the collapse of the brain cells responsible for memory.
