A hormone is a chemical released by one or more cells that affects cells in other parts of the organism. Only a small amount of hormone is required to alter cell metabolism. It is essentially a chemical messenger that transports a signal from one cell to another.

Study sheds light on how 'flight-or-flight' response impairs long-term health

Research from the lab of Mark Alkema, PhD, professor of neurobiology, sheds light on how the "flight-or-flight" response impairs long-term organism health.

Fatty food changes the brain to affect homeostasis and metabolism

While we all know that eating fatty food pushes up our body weight, a new study now shows it also affects the way the brain keeps track of and corrects all metabolic irregularities in the body. Soon after tucking into a high-fat, high-carb meal – as soon as three days later – the hypothalamus shows inflammation.

Higher levels of serotonin after a seizure linked to lower incidence of breathing problems

Could a chemical produced by the brain that regulates mood, sleep and breathing also be protective in people with epilepsy? New research has found that higher levels of serotonin in the blood after a seizure are linked to a lower incidence of seizure-related breathing problems called apneas, when a person temporarily stops breathing.

Researchers develop new technique for rapid breakdown of cellular proteins

Cellular functions depend on the functionality of proteins, and these functions are disturbed in diseases. A core aim of cell biological research is to determine the functions of individual proteins and how their disturbances result in disease.

Testosterone-containing nasal spray offers promising alternative for people suffering from 'low T'

A newly patented, testosterone-containing nasal spray developed by a psychology professor at The University of Texas at Austin could provide those suffering from testosterone deficiency and other ailments, such as anxiety disorders, with easily modulated, fast-acting results.

Resistance to 'hunger hormone' linked with cognitive impairments and memory loss

Scientists at The University of Texas at Dallas have found evidence suggesting that resistance to the "hunger hormone" ghrelin in the brain is linked to the cognitive impairments and memory loss associated with Alzheimer's disease.

Melatonin promises to help reduce bone loss in space flight

New research suggests that the problem of bone loss caused by microgravity conditions in space flight may be successfully treated using the time-tested drug melatonin. Melatonin increases the level of calcitonin in bone, which suppresses the bone-destroying activity of osteoclastic cells and helps maintain bone density.

Breast cancer gene could be key to developing targeted therapy for hepatoblastoma

Hepatoblastoma is a rare form of liver cancer affecting just a few individuals per million. However, it is the leading cause of liver cancer in infants and young children, with most patients diagnosed before their third birthday.

Presence of XX sex chromosomes increases risk of heart attacks and coronary artery disease

New research at the University of Kentucky has confirmed that the presence of XX sex chromosomes increases the amount of fat circulating in the blood, which leads to narrowing of the arteries and ultimately a higher risk of heart attacks and coronary artery disease.

Overweight adolescents actually eat less when exposed to stressful events

People often react to stress by binging on sweets or fattening comfort foods, cravings fueled by the appetite-stimulating stress hormone cortisol.

Breast cancer cells can go into sleep mode and relapse in the future

Breast cancer is one of the most aggressive types of cancers in the world. It is the commonest cause of cancer death in women worldwide, and it represented about 12 percent of all new cancer cases in 2012. Current predictions and statistics suggest that both worldwide incidence of breast cancer and related mortality are on the rise. Globally, breast cancer now represents one in four of all cancers in women.

Lack of sexual activity in older adults linked to health problems

The lack of sexual activity and function among older adults is linked to poorer health outcomes, including cancer, coronary heart disease (CHD), and fair or poor self-rated health, a new sexual science study found.

New discovery may help identify type 1 diabetes earlier than is currently possible

Type 1 diabetes, an autoimmune disease that typically emerges before the age of 20, wipes out the body's ability to produce insulin--a hormone that's essential to life. Diagnosis often comes after symptoms arise, at which point the disease has taken hold.
