Published A subtype of depression identified
(via sciencedaily.com) Original source Using surveys, cognitive tests and brain imaging, researchers have identified a type of depression that affects about a quarter of patients. The goal is to diagnose and treat the condition more precisely.
Published Chronic stress-related neurons identified
(via sciencedaily.com) Original source Researchers have identified a group of nerve cells in the mouse brain that are involved in creating negative emotional states and chronic stress. The neurons, which have been mapped with a combination of advanced techniques, also have receptors for estrogen, which could explain why women as a group are more sensitive to stress than men.
Published Research challenges current thinking on the genetic causes of very early menopause
(via sciencedaily.com) Original source The genetic causes of very early menopause will have to be reconsidered after researchers found that nearly all women who carried variations thought to cause the condition in fact had their menopause at an older age.
Published One in five women become pregnant naturally after having a baby conceived with IVF
(via sciencedaily.com) Original source New research analyzed data from 11 studies of over 5,000 women around the world between 1980 and 2021, to evaluate how common it is to get pregnant naturally after having a baby conceived by fertility treatment. Around 20% of women who needed fertility treatment, such as IVF, to conceive their first child are likely to get pregnant naturally in the future, finds a new study.
Published New diagnostic finds intact sperm in infertile men
(via sciencedaily.com) Original source Researchers develop new diagnostic tool to visualize protein biomarkers of well-developed sperm to determine if surgical sperm extraction may be successful for certain infertile men.
Published Elimination of type of bacteria suggests treatment for endometriosis
(via sciencedaily.com) Original source A research group has discovered that using an antibiotic to target Fusobacterium, a common bacterium that causes inflammation, improved the symptoms of endometriosis. Their findings suggest an alternative treatment for the disease.
Published Serotonin booster leads to increased functional brain connectivity
(via sciencedaily.com) Original source Cognitive deficits accompany mood disorders and other psychiatric conditions, often with debilitating effects. Limited treatments currently exist, but studies in animals and humans have pointed to drugs such as the laxative prucalopride that activate serotonin receptors as a potential therapeutic for the symptoms. It has remained unclear, however, how the medication affects resting brain activity. Now, a new study examines the drug's effects in healthy human adults.
Published New study links contraceptive pills and depression
(via sciencedaily.com) Original source Women who used combined contraceptive pills were at greater risk of developing depression than women who did not, according to a new study. Contraceptive pills increased women's risk by 73 per cent during the first two years of use.
Published Obesity increases risk of mental disorders throughout life
(via sciencedaily.com) Original source Being obese significantly increases the chances of also developing mental disorders. This applies to all age groups, with women at higher risk than men for most diseases.
Published Researchers successfully induce primate oocytes in the lab
(via sciencedaily.com) Original source The many types of cells in the human body are produced through the process of differentiation, in which stem cells are converted to more specialized types. Currently, it is challenging for researchers to control the differentiation of stem cells in the lab (in vitro). Of particular interest are oocytes, which are female germ cells that develop into eggs. Understanding their development could have far-ranging impacts, from infertility treatment to conservation of endangered species. A new study has successfully induced meiotic (dividing) oocytes from the embryonic stem cells of cynomolgus monkeys, which share many physiological traits with humans. By establishing a culture method for inducing the differentiation of meiotic oocytes, the researchers aimed to shed light on germ cell development in both humans and other primates.
Published Researchers treat depression by reversing brain signals traveling the wrong way
(via sciencedaily.com) Original source A new study has revealed how magnetic stimulation treats severe depression: by correcting the abnormal flow of brain signals.
Published AI voice coach shows promise in depression, anxiety treatment
(via sciencedaily.com) Original source A study found changes in patients' brain activity along with improved depression and anxiety symptoms after using Lumen.
Published Potential found to counter depression by restoring key brain rhythm
(via sciencedaily.com) Original source A new study in mice and rats found that restoring certain signals in a brain region that processes smells countered depression.
Published Anti-depressant agent KNT-127 reduces stress as well as depression
(via sciencedaily.com) Original source Depression is a condition affecting millions across the globe. However, efficient drugs with minimal adverse effects are scarce. Now, researchers have reported how KNT-127, a delta opioid receptor agonist, quickly and efficiently reduces classic parameters of depression in a mouse model. This anti-depressant agent exhibits the dual nature of being a stress reliever and an anti-depressant and could broaden the potential of existing treatments.
Published Happy worms have healthy eggs
(via sciencedaily.com) Original source Researchers have exposed roundworms (a well-established model organism in biological research) to selective serotonin reuptake inhibitors (SSRIs), a class of drugs used for treating depression and anxiety. Surprisingly, this treatment improved the quality of aging females' egg cells.
Published Scientists discover the dynamics of an 'extra' chromosome in fruit flies
(via sciencedaily.com) Original source Most chromosomes have been around for millions of years. Now, researchers have revealed the dynamics of a new, very young chromosome in fruit flies that is similar to chromosomes that arise in humans and is associated with treatment-resistant cancer and infertility. The findings may one day lead to developing more targeted therapies for treating these conditions.
Published Mental imagery a helpful way to distract teens from negative thought patterns
(via sciencedaily.com) Original source For adolescents who may get stuck in negative thought spirals, refocusing on mental imagery is a more effective distraction than verbal thoughts.
Published Problems with 'pruning' brain connections linked to adolescent mental health disorders
(via sciencedaily.com) Original source Problems with the brain's ability to 'prune' itself of unnecessary connections may underlie a wide range of mental health disorders that begin during adolescence, according to research published today. The findings may help explain why people are often affected by more than one mental health disorder, and may in future help identify those at greatest risk.
Published Diet high in fruit and vegetables linked to lower miscarriage risk
(via sciencedaily.com) Original source A preconception and early-pregnancy diet that contains lots of fruit, vegetables, seafood, dairy, eggs and grain may be associated with reducing risk of miscarriage, a new review of research suggests.
Published New genetic target for male contraception identified
(via sciencedaily.com) Original source Discovery of a gene in multiple mammalian species could pave the way for a highly effective, reversible and non-hormonal male contraceptive for humans and animals. Researchers identified expression of the gene, Arrdc5, in the testicular tissue of mice, pigs, cattle and humans. When they knocked out the gene in mice, it created infertility only in the males, impacting their sperm count, movement and shape.
