The involved scientists hypothesized that the improvement in terms of performance can be attributed to the fact that testosterone is known for increasing the appetite for risk and confidence – two factors that are good enough for augmenting the performance of a trader.

The study noted that naturally produced steroids in the body, especially cortisol and testosterone, can have a positive influence when it comes to finding as to how and why people caught in crashes often find it tedious to make a rational decision.

Discovery of worm hormone can assist fight against parasitic diseaseHormone-like molecules in tiny worms known as nematodes perform on the same line as specific human hormones - a finding that may one day prove effective for eliminating worm infections afflicting a third of the world’s population.

A molecule was discovered by researchers from the UT Southwestern that is responsible for activating genes involved in the development and reproduction of Caenorhabditis elegans, a common research worm.

This research was funded by HHMI, the Welch Foundation, the National Institutes of Health, the Jay and Betty Van Andel Foundation, the Department of Defense and the Glenn/AFAR Breakthroughs in Gerontology.a

Performance of financial traders affected by hormone levelsAccording to a new research conducted at the University of Cambridge, City traders are likely to make more than average profits when they have high morning testosterone levels.

It was hypothesized by the involved scientists that this improved performance may be because of the fact that testosterone is known to increase appetite for risk and confidence – two qualities that can easily augment the performance of any trader.

Testosterone is a steroid hormone that controls competitive encounters and sexual behavior.

It was concluded that the influence of naturally produced steroids in the body, especially cortisol and testosterone, can provide insights into how and why people caught in crashes often find it tedious to make a rational decision.

Boosting Cortisol Levels Benefits CFS And Fibromyalgia PatientsA California doctor had claimed that chronic fatigue syndrome (CFS) and fibromyalgia can be treated by boosting stress hormone cortisol with low doses of hydrocortisone. According to Dr. Kent Holtorf, the treatment offers great health benefits with less risk, compared to other treatments for the two conditions.

Doctor Holtorf believes that patients with chronic fatigue syndrome and fibromyalgia have low levels of steroid hormone cortisol. These conditions are due to dysfunction in a brain system that regulates response to stress, known as the hypothalamic-pituitary-adrenal axis.

Based on the experiment conducted by Dr. Holtorf, the treatment showed that significant percentage of chronic fatigue syndrome and fibromyalgia patients have improved. However, some patients also experienced side effects especially those administered with higher steroid doses.

  ADOLESCENT BOYS WITH ASPERGER SYNDROME SHOW NO CORTISOL RESPONSE

ADOLESCENT BOYS WITH ASPERGER SYNDROME SHOW NO CORTISOL RESPONSEIn a recent study, UK researchers reported that adolescent boys suffering from Asperger syndrome did not show any response linked with cortisol flow. Cortisol is a steroid hormone produced by the adrenal gland and released in response to stress. Upon awakening there is a surge to cortisol, which can explain some of the symptoms of Asperger syndrome.

The research team explained in an article published in the journal Psychoneuroendocrinology that along with other functions, the ability to adapt changes is controlled by the hypothalamic-pituitary-adrenal axis, which controls increase of cortisol during awakening period and this is referred as “the cortisol awakening response.”

“The cortisol awakening response is a robust and reproducible neuroendocrine phenomenon which has been positively correlated with psychological and physical well-being,” they added.

Dr. Mark Brosnan from University of Bath and his colleagues said that their study focused on the lack of response in individuals with Asperger syndrome. They also said that the research might help in explaining why such people face difficulties if even minor changes happened in their routine or environment.

During the research, the investigators measured cortisol amount in saliva of 20 adolescent males with the problem and 18 normal control individual at the time of awakening and 30 minutes later. A significant cortisol awakening response was evident in the control group while in the Asperger group the response was absent.

Brosnan and colleagues write in the article that in the study, the typical marked rise in cortisol peaks around 30 minutes after waking and was found of required level only in developing control group. Therefore, Asperger syndrome, at least in adolescent males, appeared to be characterized by an impaired cortisol awakening response. However, they also said that further research would be required to address this “intriguing phenomenon” in Asperger syndrome.
