Published High levels of maternal stress during pregnancy linked to children's behavior problems (via sciencedaily.com) Original source
Children whose mothers are highly stressed, anxious or depressed during pregnancy may be at higher risk for mental health and behavior issues during their childhood and teen years, according to new research.
Published Early-life stress changes more genes in brain than a head injury (via sciencedaily.com) Original source
A surprising thing happened when researchers began exploring whether early-life stress compounds the effects of a childhood head injury on health and behavior later in life: In an animal study, stress changed the activation level of many more genes in the brain than were changed by a bump to the head.
Published Blood clotting risk quickly drops after stopping hormonal contraceptives (via sciencedaily.com) Original source
Using birth control pills and other hormone-based contraceptives is known to elevate the risk of blood clots, but a new study suggests that this risk largely goes away within two to four weeks after one stops using these contraceptives. The findings can help patients and doctors weigh the benefits and risks of hormonal contraceptives and guide when to stop using them ahead of events that could further increase the risk of dangerous clots, such as major surgery, prolonged periods of immobility, or when tapering anticoagulant medications after a blood clot.
Published Why we don't all develop posttraumatic stress disorder after trauma (via sciencedaily.com) Original source
Researchers show why only a subset of individuals exposed to trauma develop posttraumatic stress disorder (PTSD). The research, centered on the body's stress hormone response, could pave the way for more targeted treatments for PTSD.
Published Visualizing fungal infections deep in living host tissue reveals proline metabolism facilitates virulence (via sciencedaily.com) Original source
Scientists have published the first successful application of 2-photon intravital microscopy (IVM) to image the dynamics of fungal infections in the kidney of a living host. The study reveals that the opportunistic human fungal pathogen Candida albicans requires the ability to metabolize proline, an amino acid obtained from the host, to mount virulent infections.
Published New clues to the mechanism behind treatment-resistant depression (via sciencedaily.com) Original source
Major depressive disorder (MDD) is a widespread mental health condition that for many is disabling. It has long been appreciated that MDD has genetic as well as environmental influences. In a new study researchers identify a gene that interacted with stress to mediate aspects of treatment-resistant MDD in an animal model.
Published Fungal infection in the brain produces changes like those seen in Alzheimer's disease (via sciencedaily.com) Original source
Researchers have discovered how the fungus Candida albicans enters the brain, activates two separate mechanisms in brain cells that promote its clearance, and, important for the understanding of Alzheimer's disease development, generates amyloid beta (Ab)-like peptides, toxic protein fragments from the amyloid precursor protein that are considered to be at the center of the development of Alzheimer's disease.
Published Brain is 'rewired' during pregnancy to prepare for motherhood (via sciencedaily.com) Original source
Researchers have shown that pregnancy hormones ‘rewire’ the brain to prepare mice for motherhood. The findings show that both estrogen and progesterone act on a small population of neurons in the brain to switch on parental behavior even before offspring arrive. These adaptations resulted in stronger and more selective responses to pups.
Published Study indicates possible link between chronic stress and Alzheimer's disease (via sciencedaily.com) Original source
Researchers have published a study that addresses possible associations between chronic stress, mild cognitive impairment and Alzheimer’s disease. The study shows how people aged between 18 and 65 with a previous diagnosis of chronic stress and depression were more likely than other people to be diagnosed with mild cognitive impairment or Alzheimer’s disease.
Published Posttraumatic brain activity predicts resilience to PTSD (via sciencedaily.com) Original source
After a traumatic experience, most people recover without incident, but some people -- between 2% and 10% -- develop posttraumatic stress disorder (PTSD), a mental health condition that can cause debilitating symptoms of anxiety due to emotional dysregulation. PTSD symptoms are present in up to 40% of trauma survivors in the acute aftermath of trauma, but full-blown PTSD develops in only a small subset of cases. Early identification of those at risk is critical for both early treatment and possible prevention.
Published New device rapidly controls postpartum hemorrhage (via sciencedaily.com) Original source
A study led by obstetricians has shown that a new device can rapidly control postpartum hemorrhage, a major cause of severe maternal morbidity and death, in a wide range of patients.
Published Natural compound found in plants inhibits deadly fungi (via sciencedaily.com) Original source
A new study finds that a natural compound found in many plants inhibits the growth of drug-resistant Candida fungi -- including its most virulent species, Candida auris, an emerging global health threat.
Published Your body's own cannabinoid molecules calm you during stress (via sciencedaily.com) Original source
When you're under stress, your brain may release its own cannabinoid molecules to calm you, activating the same brain receptors as THC derived from cannabis plants. But the brain activity regulated by these cannabinoid molecules were not well known. A new study in mice has discovered a key emotional brain center, the amygdala, releases cannabinoid molecules under stress that dampen the incoming stress alarm from the hippocampus, a memory and emotion center in the brain. The finding may reveal novel therapeutic targets for the treatment of stress-related disorders.
Published Active children are more resilient (via sciencedaily.com) Original source
The school year has hardly begun and the first exams are already approaching. According to findings by researchers from the University of Basel, school children cope better with the stress if they get plenty of daily exercise.
Published Stress and insomnia linked to irregular heart rhythms after menopause (via sciencedaily.com) Original source
A study of more than 83,000 questionnaires by women ages 50-79, found more than 25% developed irregular heart rhythms, known as atrial fibrillation, which may increase their risk for stroke and heart failure.
Published A gut hormone for controlling appetite doubles as an immune regulator for the fungal microbiome (via sciencedaily.com) Original source
Peptide YY (PYY), a hormone produced by gut endocrine cells that was already known to control appetite, also plays an important role in maintaining the balance of fungi in the digestive system of mammals, according to new research.
Published Deadly fungus beaten with new type of treatment (via sciencedaily.com) Original source
Researchers have discovered a new way to attack fungal infections. The key is to block fungi from being able to make fatty acids, the major component of fats. Resistance to anti-fungal drugs is increasing and this new approach will be particularly useful because it works in a new way and affects a broad range of fungal species.
Published High-quality sleep promotes resilience to depression and anxiety (via sciencedaily.com) Original source
Research has shown quality sleep can help bolster resilience to depression and anxiety.
Published New study using human fibroid cells supports use of green tea compound as treatment for uterine fibroids (via sciencedaily.com) Original source
In a pre-clinical, proof-of-concept study, researchers found that epigallocatechin gallate (EGCG), a green tea compound with powerful antioxidant properties, could be promising for both treating and preventing uterine fibroids. Results of the study add to growing evidence that EGCG may reduce fibroid cell growth. The study was specifically designed to identify the biochemical mechanisms responsible for EGCG action in fibroid cells.
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.
