Hormone regulates fondness for food

...general. Research is needed to find out how leptin triggers other chemicals in the brain and how alteration of these pathways contributes to overeating and obesity. Understanding how brain systems interact with hormones that signal hunger and energy stores will provide us with a more complete picture of fa...

Why women get more migraines than men

...s these include genes, hormones and environmental triggers such as stress, diet, changes in sleep patterns and a host of others. While it is known that migraines in females fluctuate with the menstrual cycle and are more frequent during the menstrual period, the study results appear to be independent of a sp...

Chemical in brain acts like a fuel gauge

The concept that a drop in blood sugar triggers a craving for food is best understood just before lunchtime. But exactly how the process unfolds has proven difficult to explain, even on a full stomach. Solving the puzzle would yield new insights in the fight against diabetes. Neuroscientists ...

Mayo researchers discover overdiagnosis of long QT heart syndrome

...th, often related to physical exertion or auditory triggers such as an alarm clock. However, most cases can be diagnosed following warning signs that suggest its potential presence and from objective data derived from an electrocardiogram (ECG), exercise or adrenalin stress testing, and genetic testing.

'Energy Up' demonstrates success as obesity intervention program for inner-city girls

...based program does. Studies show that binge eating triggers the same neurological pathways as drug addiction, so Voltages theories are rooted in science. Furthermore, recent studies of carbohydrate consumption support that these foods affect satiety, and can trigger over eating. The corner stone of "Energy ...

Detecting cold, feeling pain: Study reveals why menthol feels fresh

..., and in 2000 reported that, in mice, the receptor triggers the nerves to fire pain signals when they are exposed to high ambient heat or the fiery properties of peppery food. (Science, April 14, 2000). The study demonstrated that capsaicin and noxious heat elicit the sensation of burning pain through activat...

Mercury's link to heart disease begins in blood vessel walls

... can be traced to activation of this enzyme, which triggers a process leading to plaque buildup in blood vessel walls. The study examined three forms of mercury, matching its characteristics in the environment. Each form of mercury caused changes in the behavior of cells that line the blood vessel walls and...

MIT reports key pathway in synaptic plasticity

Sleep apnea increases risk of heart attack or death by 30 percent

...ography or bypass surgery) or died. Sleep apnea triggers the bodys fight or flight mechanism, which decreases the amount of blood pumped to the heart. Repeated episodes every night for a few years can starve the heart of enough oxygen when it is combined with the bodys decreased oxygen intake due to the fr...

Sleep apnea may increase risk of diabetes

...activates the bodys fight-or-flight response. This triggers a cascade of events, including the production of high levels of the hormone cortisol that ultimately leads to insulin resistance and glucose intolerance, pre-diabetic conditions that, if left untreated, can lead to the development of diabetes. Low ox...

Research demonstrates link between domestic violence and asthma

Normally, the focus of migraine treatment is to reduce the pain. Were saying that migraines may be causing brain damage, and that the focus should be on prevention, w...

Hay fever can send work productivity down the drain

...llen from grass and trees. IgE is an antibody that triggers allergic reactions. In a previous study, Szeinbach found that the ImmunoCAP IgE blood test was more accurate in diagnosing allergies when compared to other specific IgE blood tests. While IgE testing is traditionally the realm of allergists, more a...

Livestock interventions can protect lives, livelihoods

Researchers hot on the trail of brain cell degeneration

...s, neurons in the brain are over-stimulated, which triggers programmed cell death, or apoptosis. The study shows that the Rho protein, which has long been recognised as an important player in cancer formation, also plays a key role in the destruction of neurons in disease. "These surprising findings add an ...

Garlic does not appear to lower cholesterol levels

Currently, inhibition of tumor necrosis factor (TNF) is the most effective strategy for controlling the painful symptoms of SpA and slowing vertebral joint destruction. But does anti-TNF therapy do anything to reduce the...

Media coverage of autism differs dramatically
