A testosterone patch may produce modest increases in sexual desire and frequency of satisfying sexual experiences in women who develop distressful, low sexual desire following hysterectomy and removal of the fallopian tubes and ovaries, according to a study in the July 25 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Diminished sexual desire has been reported by 30 to 50 percent of women who undergo surgical menopause (menopause induced by the surgical removal of both ovaries), according to background information in the article. In one form of female sexual dysfunction, hypoactive sexual desire disorder, a chronic absence of desire for sexual activity results in personal distress. When the ovaries are removed (oophorectomy), blood levels of sex hormones, including testosterone, drop. Although some women see improvements in sexual functioning with estrogen therapy alone, previous studies suggest that the combination of estrogen and testosterone is more effective in preserving sexual desire.
Glenn D. Braunstein, M.D., of Cedars-Sinai Medical Center, Los Angeles, and colleagues conducted a 24-week, randomized, double blind, multicenter clinical trial in women who developed distressful low sexual desire after surgical menopause and were receiving oral estrogen therapy. The 447 women (aged 24 to 70 years) were randomized to receive placebo or testosterone patches twice weekly in one of three progressively higher doses. Testosterone levels were checked at baseline, 12 and 24 weeks. Changes in sexual desire and frequency of satisfying sexual activity were determined on the basis of a woman’s reports on standardized questionnaire and sexual function activity log.

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
