Elevated levels of erythropoietin in brain motivates to exercise
06/12/2012 - 19:49

A team of Swiss researchers found that when a hormone in the brain, erythropoietin (Epo), was elevated in mice, they were more motivated to exercise. In addition, the form of erythropoietin used in these experiments did not elevate red blood cell counts. Such a treatment has obvious benefits for a wide range of health problems ranging from Alzheimer's to obesity, including mental health disorders for which increased physical activity is known to improve symptoms.

Protein signal is crucial for accurate control of insect size
05/04/2012 - 08:58

Two independent groups of researchers have identified a hormone that is responsible for keeping the growth and development of insects on track. The results, which are reported in the journal Science, suggest that Dilp8 provides an important signal to slow body growth and delay insect development. This braking effect is an essential part of normal development since it allows sufficient time for tissues to form and the correct body size, proportions and symmetry to be achieved.

When babies awake: New study shows surprise regarding important hormone level

Cortisol may be the Swiss Army knife of hormones in the human body-just when scientists think they understand what it does, another function pops up. While many of these functions are understood for adults, much less is known about how cortisol operates in babies and toddlers, especially when it comes to an important phenomenon called the cortisol awakening response, or CAR.

Hormone in birth control shot linked to memory loss

The birth control shot offers a convenient alternative to women who don’t want to remember to take a daily pill. Ironically, recent research from ASU’s Bimonte-Nelson Memory and Aging Laboratory has shown the shot may not be helping memory. In fact, it may be harming it.

No increase in commonest preventable cause of intellectual disability over 20 years
07/19/2011 - 09:13

A new study that was prompted by recent reports of an increase in cases of congenital hypothyroidism in the United States, and aimed at assessing the incidence of this condition among Quebec newborns, suggests that the increase is entirely artifactual. CH is characterized by inadequate thyroid hormone production and is the most common cause of preventable intellectual disability. The results were published in the Journal of Clinical Endocrinology and Metabolis by Dr. Johnny Deladoëy, a pediatric endocrinologist and researcher in metabolic and genetic diseases at CHU Sainte-Justine Research Center and an assistant professor of pediatrics and biochemistry at University of Montreal
