Estradiol fluctuation may enhance emotional sensitivity to psychosocial stress during menopausal transition

If you're feeling a little blue during the transition to menopause, there's good reason, according to a new study being reported online today in Menopause, the journal of The North American Menopause Society (NAMS). The study from the Department of Psychiatry at the University of North Carolina at Chapel Hill suggests that the estradiol (a form of estrogen) fluctuation that is common during the menopausal transition may enhance emotional sensitivity to psychosocial stress.

Oxford professor wins Heinrich Wieland Prize for pioneering method that helps control nerve cells with light

Gero Miesenböck was the first to insert a light-controlled on/off switch into brain cells. His pioneering method allows scientists to switch nerve cells on and off selectively and observe how the behaviour of, for example, fruit flies or mice changes as a result. In this way, researchers can learn in a step-by-step process what behaviour the studied brain circuits control and what goes awry in disease. For his method, hailed as a "breakthrough of the decade," Professor Gero Miesenböck of the University of Oxford will receive the 100,000-euro Heinrich Wieland Prize of the Boehringer Ingelheim Foundation in Munich on November 6, 2015.

Study explores benefits of breast cancer adjuvant therapies

After breast cancer surgery, women are prescribed adjuvant (or follow-up) therapies such as chemotherapy and endocrine drugs to reduce the risk of the cancer returning. It's been assumed that the treatment effects of these therapies remain constant over time, but a new study from the Cancer Therapy & Research Center (CTRC) at The University of Texas Health Science Center at San Antonio suggests the opposite is true.

Elderly women should take more vitamin D supplementation during the wintertime, suggests researchers

Osteoporosis is one of the chief reasons why the elderly often suffer broken bones from relatively minor injuries. Postmenopausal women in particular experience a relatively rapid loss in bone mass due to a reduced concentration of oestrogen, which is responsible for strong bone growth during youth. Maintaining bone mass requires physical exercise and vitamin D, which is mainly produced in the skin with the help of UVB radiation. This is why, especially in the wintertime, many elderly women are prescribed a vitamin D supplement by their doctor to maintain bone mass.

Chemotherapy treatment can contribute to long-term neurocognitive deficits in pediatric brain tumor survivors

More children are surviving malignant brain tumors than in the past, thanks to the use of intense treatments using platinum-based chemotherapy (cisplatin and high-dose carboplatin). Unfortunately, the therapy has a known side effect of permanent hearing loss, resulting from damage to the inner ear.

TUM researchers uncover signaling pathways that play vital role in self-renewal of blood stem cells

Stem cells have two important capabilities: they can develop into a wide range of cell types and simultaneously renew themselves, creating fresh stem cells. Using a model of the blood forming (hematopoietic) system, researchers at the Technical University of Munich have now been able to precisely determine, which signaling pathways play an essential role in the self-renewal of blood stem cells.

Blood stem cell self-renewal dependent on surroundings

Stem cells have two important capabilities: they can develop into a wide range of cell types and simultaneously renew themselves, creating fresh stem cells. Using a model of the blood forming (hematopoietic) system, researchers at the Technical University of Munich (TUM) have now been able to precisely determine, which signaling pathways play an essential role in the self-renewal of blood stem cells. A particularly decisive role in this process is the interactive communication with surrounding tissue cells in the bone marrow.
