Chemical Injections for Fat Removal

...ume. This pathway involves two players − a neurotransmitter (neuropeptide Y, or NPY) and the receptor (neuropeptide Y2 receptor, or Y2R) it activates in two types of cells in the fat tissue: endothelial cells lining blood vessels and fat cells themselves. In order to add fat selectively to the mice they te...

Scientists Discover Key to Manipulating Fat

... consume. This pathway involves two players -- a neurotransmitter (NPY) and the receptor (Y2R) it activates in the fat tissue: endothelial cells lining blood vessels and fat cells themselves. In order to add fat selectively to the mice they tested, researchers injected NPY into a specific area. They found that both...

Neurotransmitter That can Yield New Insights in the Fight Against Diabetes Identified

...new insights in the fight against diabetes, is the neurotransmitter norepinephrine. According to the researchers, the chemical travels from the hindbrain, which receives warnings of low glucose levels from the body, to the paraventricular hypothalamus, which authorises the consumption of energy stores to replace t...

...e powers of a feel-good hormone called oxytocin, a neurotransmitter in the brain that is involved in social recognition and bonding. The mammalian hormone is produced naturally by the body when a person is in love, and it also induces labour in pregnant women. The spray contains a synthetic version of it, created ...

Genetic Tests Could Help Decide the Right Anti-depressants

...identified genetic variations that affect specific neurotransmitter functions, which could explain why some patients respond to some drugs but not to others. For example, some depressed patients respond quickly to selective serotonin reuptake inhibitors (SSRIs), which relieve depression, in part, by flooding the br...

"This is the strongest evidence to date that urate may protect against Parkinson's disease," said lead author Marc Weisskopf, Assistant Professor of Environmental and Occupational E...

High Urate Levels in Blood Linked to Reduced Parkinson's Risk

Marc Weisskop said that the results of the study provided the 'strongest evidence to date' that urate, a normal component of blood might also have beneficial effects in its capacity...

Gene Therapy for Parkinsons Disease

...boxylase. This enzyme is critical in controlling a neurotransmitter called GABA. In Parkinsons, GABA is reduced in an area of the brain called the subthalamic nucleus. This region is working on overdrive in the disease process and GABA is an inhibitory transmitter and is important in trying to calm this hyper-react...

Common Antidepressants Linked to Increased Bone Loss in Older Adults

The findings raise the possibility that SSRIs, which are often prescribed to the elderly, may affect bone...

Antidepressents may Lower Bone Density in Older People

...nhibiting the protein that transports serotonin, a neurotransmitter involved in sleep and depression. This protein has recently been discovered in bone as well, raising the possibility that SSRIs may affect bone density and the risk of fracture. SSRIs account for about 62 percent of antidepressant prescriptions in ...

Researchers Have Found Clue to How Fear Changes into Phobia

... that mice, in which a particular receptor for the neurotransmitter serotonin, called 5-Htr1a, was removed, found perceived potentially dangerous situations as big a threat as dangerous ones. They noted that mice in which the receptor had been removed could not evaluate the true threat of an ambiguous situation, re...

Such neurotransmitters are the chemical signals that one neuron launches at another to trigger a nerve impulse in the receiving neuron. In their studies, Mansvelder and colleagues found that by activating acetylcholine receptors, nic...
