The pain-relieving effects of nitrous oxide — laughing gas — may be enhanced by suggestion or hypnosis, according to a new study. The study’s findings — that people are more suggestible under the gas — mean that dental patients may benefit from being coached to relax while undergoing sedation.

Research on the mechanisms involved in neurodegenerative diseases such as Alzheimer’s, stroke, dementia, Parkinson’s and multiple sclerosis, to name a few, has taken a step forward thanks to the work of researchers who have successfully demonstrated the protective and reparative role of apolipoprotein D, or ApoD, in neurodegenerative diseases. Their discovery suggests interesting avenues for [...]

A powerful new tool that can extract features and patterns from enormously large and complex data sets has been developed. The tool — a set of problem-solving calculations known as an algorithm — is compact enough to run on computers with as little as two gigabytes of memory.

The 1995 discovery of leptin, an appetite-suppressing hormone, generated great hopes for an effective obesity drug. But hopes dimmed when it was found that obese people are leptin-resistant. Now, researchers have, for the first time, re-sensitized the brain to leptin, using oral drugs that are already FDA-approved. In mice, this led to significant weight loss [...]

Researchers have developed a new generation of microscopic particles for molecular imaging, constituting one of the first promising nanoparticle platforms that may be readily adapted for tumor targeting and treatment in the clinic.
Treatment with a pharmacological version of the drug ecstasy makes PSTD patients more receptive to psychotherapy, and contributes to lasting improvement. Now researchers explain why.

Scientists have investigated the frequency of warmer than average years between 1880 and 2006 for the first time. The result: the observed increase of warm years after 1990 is not a statistical accident.

Researchers have discovered that the nerve cells controlling heart rate and blood pressure synthesize a molecule known to be critically important for proper nervous system growth. The finding could someday play a significant role in the prevention of sudden infant death syndrome and high blood pressure.

Scientists have found that the compound, present in olive skin’s leaf and wax, inhibits the growth of HT29 colon-cancer cells. It may provide a useful new therapeutic strategy for the treatment of colon carcinoma. Low concentrations of maslinic acid are to be found in plants with medicinal properties, but its concentration in the waxy skin [...]

A new report underscores the notion that stroke risks go beyond geographic and racial differences. Researchers report that non-traditional risk factors must explain the South’s higher stroke death rate. What those factors are need further study, but clearly diabetes and hypertension play an important role, the study authors said.
