Ghrelin, a hormone produced in the stomach, may be used to boost resistance to, or slow, the development of Parkinson's disease, Yale School of Medicine researchers report in a study published in a recent issue of the Journal of Neuroscience. Parkinson's disease is caused by a degeneration of dopamine neurons in an area of the midbrain known as the substantia nigra, which is responsible for dopamine production. Reduced production of dopamine in late-stage Parkinson's causes symptoms such as...

Researchers have discovered a genetic variation that may contribute to how empathetic a human is, and how that person reacts to stress. In the first study of its kind, a variation in the hormone/neurotransmitter oxytocin's receptor was linked to a person's ability to infer the mental state of others. Interestingly, this same genetic variation also related to stress reactivity. These findings could have a significant impact in adding to the body of knowledge about the importance of oxytocin,...

A new study carried out at the University of Haifa has found that the oxytocin hormone, known as the 'love hormone,' also affects antisocial behaviors, such as envy and gloating A new study carried out at the University of Haifa has found that the hormone oxytocin, the "love hormone", which affects behaviors such as trust, empathy and generosity, also affects opposite behaviors, such as jealousy and gloating. "Subsequent to these findings, we assume that the hormone is an overall trigger for...

New research suggests that a drug used to treat cancer could possibly stop contractions and even prevent premature labor, BBC News reported. The drug Trichostatin A was tested on tissue taken from 36 women undergoing a caesarean, according to a team of researchers from The Newcastle University. They found that the therapy worked by increasing the levels of a protein that controls muscle relaxation -- a much need treatment, as there are over 50,000 premature births every year in the UK and...

A new study indicates a link between autism and alterations to the oxytocin receptor, OXTR, caused by inherited alterations that do not involve DNA sequence mutation. The study, published in the open access journal BMC Medicine, identified the non-DNA change in 'OXTR' via an autistic child and his mother, who potentially has obsessive-compulsive disorder. Dr Simon Gregory headed up a team from the US, UK and Italy, who analyzed the DNA of 119 people with autism and 54 neurotypical...

Researchers at Duke University Medical Center have uncovered a new genetic signature that correlates strongly with autism and which doesn't involve changes to the DNA sequence itself. Rather, the changes are in the way the genes are turned on and off. The finding may suggest new approaches to diagnosis and treatment of autism. The researchers found higher-than-usual numbers of gene-regulating molecules called methyl groups in a region of the genome that regulates oxytocin receptor expression...

Researchers at the Yerkes National Primate Research Center, Emory University, have demonstrated that prairie voles may be a useful model in understanding the neurochemistry of social behavior. By influencing early social experience in prairie voles, researchers hope to gain greater insight into what aspects of early social experience drive diversity in adult social behavior. The study is currently available online in a special edition of Frontiers in Behavioral Neuroscience that is focused on...

The sight of their infants' smiles and tears lights up the brain reward centers of mothers who have a secure attachment to their own parent(s), said researchers from Baylor College of Medicine (www.bcm.edu) in a report that appears in the current issue of the journal Neuropsychopharmacology. Attachment is based on the mother's perception of her own childhood experience, said Dr. Lane Strathearn, lead author of the paper and an assistant professor of pediatrics "“ developmental at BCM...

Increased sexual activity may lead to an improvement in problem-solving, confidence and teamwork at work, a U.S. researcher says. Dr. Helen Fisher, chief scientific adviser to the Web site Chemistry.com, says her research focused on a sample of 40,000 people on Chemistry.com -- 56 percent female -- with an average age of 37. In addition to being great exercise and a stress reliever, sex triggers the release of a number of valuable brain chemicals, Helen Fisher says in a statement. From...

Labor Induction is a process of giving an artificial start to birth with medical intervention or other methods. When an induction is not performed for emergency or other medical reasons, the method is considered an elective process. The decision to induce labor has increased in recent years due to its convenience or because it easily accommodates busy schedules. The American College of Obstetricians and Gynecologists, however, say that labor should only be induced when it is more risky...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
