Steroid hormone can alleviate brain's response to stressA steroid hormone, known as Progesterone metabolite allopregnanolone, which gets released during the metabolism of progesterone (the female sex hormone) can minimize brain’s response to stress.

The scientists found evidence suggesting that the human brain’s response to a peptide hormone that plays an important role in the stress response in animals, corticotropin-releasing factor (CRF), gets reduced by progesterone metabolite allopregnanolone.

The finding was disclosed by scientists at Emory University School of Medicine, the Yerkes National Primate Research Center, and Atlanta’s Center for Behavioral Neuroscience.

Researchers recommend progesterone for TBI patientsAdministration of progesterone to individuals treated for Traumatic Brain Injury (TBI) shortly after the injury has the potential of reducing the chances of death and degree of disability to a considerable extent, according to Emory University researchers.

The researchers said progesterone treatment for TBI has been extensively studied in lab animals for over 15 years with efficacy.

The research was published in the Annals of Emergency Medicine.

Progesterone supply improves brain injury outcomesResearchers from the Emory University have suggested that offering progesterone to patients treated for traumatic brain injuries, shortly after the injury, can considerably reduce the risk of death and degree of disability.

The research was published in the Annals of Emergency Medicine.

It was disclosed by the study that progesterone treatment for brain injuries is safe and has been extensively studied on animals for more than 15 years.

low-doses-of-prozac-can-help-in-relieving-pms-miseryResearchers at the University of Birmingham have found that Prozac, known generically as fluoxetine, can alleviate the misery of premenstrual syndrome (PMS) when taken in low doses.

It was found by the scientists that Prozac has the potential of raising levels of a sex hormone that can drop sharply in women at the end of their menstrual cycle.

Thelma Lovick, a neuroscientist at the University of Birmingham, is of the view that she has evidence that a 2mg daily dose of fluoxetine in the final week before menstruation could alleviate PMS.

Traumatic brain injury outcomes improve with progesteroneProviding progesterone to victims with Traumatic Brain Injury (TBI) shortly after the injury could minimize the risk of death and the degree of disability besides being safe, according to a study by researchers from Emory University.

The study disclosed that progesterone treatment for TBI has been extensively studied in laboratory animals for more than fifteen years and has demonstrated efficacy by reducing brain swelling, improved functional outcomes, and prevention of nerve death.

The research was published in the Annals of Emergency Medicine.

Progesterone metabolite allopregnanolone minimized stressProgesterone metabolite allopregnanolone, a steroid hormone released during the metabolism of progesterone (the female sex hormone) has the ability to reduce response of the brain to stress.

This finding was disclosed by scientists at Emory University School of Medicine, the Yerkes National Primate Research Center, and Atlanta’s Center for Behavioral Neuroscience.

Evidence was found by the scientists in context to the fact that response of brain to corticotropin-releasing factor (CRF), a peptide hormone that plays an important role in the stress response in animals, was reduced by progesterone metabolite allopregnanolone.

Substance loss related to nervous system complications can be reversed by steroidsScientists from the University of Illinois have reported that steroids can be more than just useful for reducing inflammation. It was disclosed that use of steroids can lead to reversal of a loss of myelin, which is a major problem in multiple sclerosis and other demyelinating diseases and injuries associated with the central and peripheral nervous systems.

It was further reported that steroids dexamethasone and progesterone can actually signal the initiation and dramatically increases in context of the rate of myelin synthesis.

The new findings were published in a biochemistry section of the Proceedings of the National Academy of Sciences.

Airway constriction in asthmatic women patients reduces with estrogenAccording to new bench research from the Mayo Clinic, female sex hormones could work with beta-agonists in minimizing airway constriction.

Lead student researcher, Elizabeth A. Townsend, of the Mayo Clinic Department of Physiology and Biomedical Engineering, said that it will be of interest to ascertain whether sex steroids such as estrogen and progesterone play a role in modulation of airway tone.

The findings are being presented at the ATS 2010 International Conference in New Orleans.

Progesterone optimization can help in treating brain injuriesResearchers have been testing optimization of Progesterone to measure the effectiveness of the hormone in treating patients afflicted with traumatic brain injuries.

This finding was highlighted by two abstracts demonstrating Emory research on the hormone that was presented at the 2009 Society for Neuroscience (SFN) meeting in Chicago; the trial was developed by Donald Stein, PhD, Asa G. Candler Professor of Emergency Medicine at Emory School of Medicine.

It was noted by authors of the study that low amounts of Vitamin D could be useful in improving progesterone’s ability to guard neurons from excito-toxicity, which is a principal cause of brain injury and death of cells.

Plants capable of making progesteroneScientists have reported the first discovery of the female sex hormone, progesterone, in a plant. This finding is considered by many as an overturn from conventional wisdom.

The discovery was reported in the American Chemical Society’s Journal of Natural Products, a monthly publication.

The involved researchers made use of two powerful laboratory techniques, nuclear magnetic resonance and mass spectroscopy, for detecting progesterone in leaves of the Common Walnut, or English walnut, tree.
