Biological responses in men influenced by olfactory cues to female ovulation

Women around the world spend billions of dollars each year on exotic smelling perfumes and lotions in the hopes of attracting a mate. However, according to a new study in Psychological Science, a journal of the Association for Psychological Science, going "au natural" may be the best way to capture a potential mate's attention.

Study reveals link between serotonin receptor number and antidepressant treatment

An excess of one type of serotonin receptor in the center of the brain may explain why antidepressants fail to relieve symptoms of depression for 50 percent of patients, a new study from researchers at Columbia University Medical Center shows.

Brain mechanisms behind compulsive behaviors in Parkinson's disease patients

New research unravels the brain mechanisms that underlie the ability of a standard drug treatment for Parkinson's to elicit compulsive behaviors in some patients with the disease. The study, published by Cell Press in the January 14th issue of the journal Neuron, provides fascinating new insight into the brain mechanisms that underlie a predisposition to behavioral addictions, such as pathological gambling and shopping.

Dopamine replacement therapy causes brain dysfunction in patients with Parkinson disease, study says

People with Parkinson's Disease are more likely to display abnormal social behaviour and make poor decisions in ambiguous circumstances if they are pathological gamblers, according to research in the January issue of the European Journal of Neurology.

New insights into molecular interaction between probiotics and altered host intestinal ecosystem in IPAA

Total proctocolectomy with ileal J-pouch-anal anastomosis (IPAA) is the surgical treatment of choice for patients with refractory ulcerative colitis (UC). Although the surgery generally cures UC allowing a significant improvement of health-related quality of life, complications can occur after IPAA.

Scientists determine structure of enzyme essential to the survival of protozoan parasites

After many years of study, a team of researchers is releasing data today that it hopes will lead to new drug therapies that will kill the family of parasites that causes a deadly trio of insect-borne diseases and has afflicted inhabitants of underdeveloped and developing nations for centuries.

Researchers identify six essential oils that can suppress inflammation

For those who do not drink, researchers have found that six essential oils -from thyme, clove, rose, eucalyptus, fennel and bergamot-can suppress the inflammatory COX-2 enzyme, in a manner similar to resveratrol, the chemical linked with the health benefits of red wine. They also identified that the chemical carvacrol was primarily responsible for this suppressive activity.

New findings reveal tendons play an active role in initiating bone ridge formation

Bones, muscles and tendons work together to provide the perfect balance between stability and movement in the skeleton. Now, Weizmann Institute scientists show that this partnership begins in the embryo, when the bones are still taking shape. The

New genetic risk factor for Parkinson's disease identified

An international team of doctors and human geneticists has identified a new genetic risk factor for Parkinson's disease. The institutions involved in the study were the Institute of Human Genetics of Helmholtz Zentrum München and Technische Universität München, the Neurological Clinic of Ludwig-Maximilians-Universität Munich (LMU) and the Mitochondrial Research Group of Newcastle University, Newcastle upon Tyne, UK.

Molecules capable of reversing brain abnormalities in PD identified

Scientists identified several molecules capable of reversing the brain abnormalities of Parkinson's disease (PD), while also uncovering new clues for its origin in a study just published in the journal Disease Models and Mechanisms. PD is characterised by abnormal deposits of a brain protein called alpha-synuclein throughout the damaged brain regions, but exactly what they do there is not clear. The fact that their numbers and spreading are associated disease progression has made them, however, a major point of interest in PD research.

Race against time to produce artificial blood substitute

The Twilight book trilogy has 'vegetarian' vampires living on animal blood and in the TV series True Blood, Japanese scientists have developed a synthetic blood substitute. However, in the most recent blockbuster movie Daybreakers, vampires suffer a horrific fate when attempting to drink their blood substitute.

Treatment for metastatic tumor based on its unique protein makeup

Imagine if treatments for disease could be based not on a patient's diagnosis but instead on the characteristics of their tissue. By identifying and decoding the cryptic messages hidden deep inside the human proteome, scientists and physicians who study personalized medicine are seeking more effective treatments and disease management for patients.
