The majority of women who undergo surgery for suspected ovarian cancer do not have cancer. A novel blood test developed by researchers at Uppsala University and the Sahlgrenska Academy, University of Gothenburg, now offers the possibility of more precise diagnostics without the need for surgery. This could lead to a reduction in unnecessary surgery and to earlier detection and treatment for affected women. The study was recently published in Communications Biology.
A new finding from University of Maryland School of Medicine (UMSOM) researchers, published in the June issue of the journal Endocrinology, could have important implications for developing novel treatments to prevent placental abnormalities.
New research by University of Wisconsin-Madison sociologist Nathan Seltzer identifies a link between the long-term decline in manufacturing jobs -- accelerated during the Great Recession -- and reduced fertility rates.
Transitions are a hallmark of life, and so there is a transition during early development when an embryo undergoes biochemical changes, switching from being controlled by maternal molecules to being governed by its own genome. For the first time, researchers have found in an embryo that activation of its genome does not happen all at once, instead it follows a specific pattern controlled primarily by the various sizes of its cells.
A new study aims to provide healthy couples who have a child affected by a developmental disorder with a personalized pre-conception risk evaluation, in order to determine the likelihood of a future child being affected by the same condition.
Sickle cell disease is a form of anemia that is inherited when both parents are carriers of a mutation in the hemoglobin gene. Currently, it can only be diagnosed in pregnancy by carrying out an invasive test that has a small risk of miscarriage and is therefore sometimes declined by parents. Now, researchers have developed a noninvasive prenatal test for the disease.
Phthalates are used by industry in plastic products. Their toxic effect on the endocrine system is worrying. Indeed, the exposure of male foetuses to phthalates can have devastating consequences for the fertility. However, researchers (UNIGE/HUG) show that phthalate susceptibility depends largely on the genetic heritage of each individual. These results raise the question of individual vulnerability and the possible transmission to future generations of epigenetic changes that should normally be erased during foetal development.
Scientists at The Graduate Center of The City University of New York and Brooklyn College have discovered seasonal changes in dopamine levels in the female plainfin midshipman fish's inner ear helps hearing sensitivity grow in the summer mating season, making her better able to hear the male's mating calls.
New research, published in the journal Scientific Reports, shows that women undergo a significant mental as well as physical change during the late stages of pregnancy.
The man is implicated in about half of all cases of infertility. Despite the known importance of genetic factors in the non-production of sperm, only about 25% of these cases can be explained currently. Now a study has uncovered new potential genetic causes, and this discovery will help to develop better diagnostic tests for male infertility.
