Researchers have identified a group of cells in the spinal cord that control ejaculation, which can be manipulated to treat sexual dysfunction. The discovery has implications for paraplegic men and those experiencing ejaculatory problems.
A Penn State study found that larger restaurant portions increase calorie intake, regardless of whether consumers eat all or most of the food. In a related two-day study, participants who received more food consumed more calories, even if they had eaten less the previous day.
Researchers used genetically modified mice to understand cocaine's brain mechanisms, revealing the drug's actions go beyond dopamine and norepinephrine transporters. The findings suggest the serotonin system may also be a target for cocaine treatment.
Dr. Sundquist's research has identified key cellular proteins necessary for HIV release, providing potential new targets for anti-HIV drugs. By altering the structure of these proteins or blocking their interaction with HIV, future treatments may slow or halt infection.
A study found that prenatal exposure to nicotine increases the function and density of GABAa receptors in brain regions controlling breathing, leading to more frequent and prolonged episodes of apnea in newborn rats. This suggests a possible link between maternal smoking during pregnancy and increased risk of Sudden Infant Death Syndro...
Researchers at UNC Chapel Hill found a third transporter, the serotonin system, plays a role in cocaine's effects on the brain. The discovery brings medical science closer to effective therapies for treating cocaine addiction.
