In vitro fertilization affects the regulatory region of genes essential for placental and embryonic growth, as well as the birth weight. A new study suggests that the effects depend on genetic variation inherited from the parents. This information could be useful in development of assisted reproduction technologies.
"Our results demonstrate, for the first time, the presence of biologically active SPGCs in testicular biopsies of chemotherapy-treated PCPBs, and their capacity to develop in vitro to different stages of spermatogenesis, including the generation of sperm-like cells," according to lead researcher Prof. Mahmoud Huleihel, a member of BGU's Shraga Segal Department of Microbiology, Immunology and Genetics. "This study may open the way for new therapeutic strategies for fertility preservation of PCPBs and for azoospermic patients."
Carnegie Mellon neuroscientists have mapped the feeling of cool touch to the brain's insula in a mouse model. The findings provide an experimental model that will advance research into conditions like pain and hypersensitivity to cold and help researchers to continue to unravel the multifaceted ways touch is represented in the brain.
Most people who misuse opioids are first exposed to the drugs through prescriptions so improving prescribing is targeted as one way to help curb the nation's opioid abuse epidemic. A new study identified six types of risky opioid prescriptions and found that all were linked to a higher chance of death, including fatal opioid overdoses. The study found more than 6 percent of Massachusetts adults received a risky opioid prescription during a five-year period.
A study of the victimization of women who were living in areas of high poverty and HIV prevalence in multiple cities across the US has shown that high-risk-sex, characterized by one or more HIV risk factors, was associated with a significantly greater likelihood of physical violence against the female participant within the subsequent six months.
Below is a summary of the new and recent research discussed at this conference.
The study of a Quebec family with an unusual gene provides novel insight into how our brain is built and, according to the McGill-led team of scientists, offers a better understanding of psychiatric disorders such as depression, addictions and schizophrenia.
Researchers found that a form of the estrogen hormone can contribute to drug relapse in females by worsening withdrawal symptoms. The study looked at the interaction of the female sex hormone estradiol and methamphetamine.
A new study shows that watching films set in a natural environment boosts body image.
One of the joys of shopping for many people is the opportunity to brag about their purchases to friends and others. But new research found one common situation in which people would rather not discuss what they just bought: when they're feeling like money is a little tight. In a series of studies, researchers found that consumers who felt financially constrained didn't want to talk about their purchases, large or small, with friends or strangers.
