A recent study has found that late menopausal status is associated with an elevated level of depressive symptoms that indicate the negative dimension of mental well-being. However, menopause was not linked to positive dimensions of mental well-being in women aged 47 to 55. The results also suggest that a high level of physical activity was linked to fewer depressive symptoms, higher satisfaction with life and higher positive affectivity in menopausal women.
The formation pressure governs the generation, expulsion, migration, accumulation and preservation of petroleum. Fluid-rock interactions during diagenesis and mineralization are also affected by the formation pressure. Thus, investigating the formation paleo-pressure in sedimentary basins is an important aspect of research into the mechanisms and processes related to hydrocarbon accumulation, and it plays an increasingly important role in hydrocarbon exploration and prospective prediction.
Across the world, animals are kept in captivity for various reasons: in zoos for education and research, in research facilities for testing, on farms for meat and other products, and in people's homes as pets. Maintaining good animal welfare is not only important for ethical reasons; poor welfare can impact human wellbeing and the economy. But how do we assess how animals are feeling?
ROCHESTER, Minn. -- Surgery performed on a fetus in the womb to repair defects from spina bifida triggers the body's ability to restore normal brain structure, Mayo Clinic research discovered.
Research by Rodrigo Ruano, M.D., Ph.D., chair of Mayo Clinic's Division of Maternal and Fetal Medicine, finds that fetal surgery to correct congenital spinal cord defects is more effective at healing neurological structure than surgery after birth. This research was published in Mayo Clinic Proceedings.
Two studies of the coronavirus COVID-19 outbreak recently published in the open-access journal PLOS ONE.
Investigators at St. Jude Children's Research Hospital have found that the ABCC4 transporter is critical to the SHH signaling pathway in the brain tumor medulloblastoma. This work provides a rationale for development of small molecule inhibitors that target ABCC4. The findings appeared in Cancer Research.
Infants who were started on solid foods at or before three months of age showed changes in the levels of gut bacteria and bacterial byproducts, called short-chain fatty acids, measured in their stool samples, according to a study from researchers at Johns Hopkins Bloomberg School of Public Health.
A team of researchers led by Patrick E. H. Jackson at the Myles H. Thaler Center for HIV and Human Retrovirus Research, University of Virginia, Charlottesville, Virginia, USA, has published a review on the subject of the HIV-1 Rev Regulatory complex (dubbed the HIV-1 Rev Regulatory Axis) in the journal, Current HIV Research. HIV-1 Rev Regulatory Axis is comprised of 2 key components which are necessary to transport viral mRNAs out of the nucleus into the cytoplasm.
Beijing, 31 March 2020: the journal Cardiovascular Innovations and Applications (CVIA) has just published a new issue, Volume 4 Issue 3 with an invitation to join the International Brugada Electrocardiographic Indices Registry
This issue brings together important research papers from leading cardiologists in US, China and Europe in a combination of reviews, original research and case reports.
Scientists from the laboratory of Dr. Natalia Kononenko at the CECAD Center of Excellence in Aging Research at the University of Cologne have found out that autophagy - the process of cellular self-recycling, or waste clearance - is dispensable for the survival of the neurons in mice. The new findings suggest that autophagy in fact also fulfils a different important function: The proteins classically associated with waste clearance in cells regulate the speed of intracellular transport. This transport is achieved by microscopic hollow tubes, so-called microtubules.
Z-form nucleic acids are double-stranded DNA and RNA molecules with an unusual left-handed double helix structure, as opposed to the classical right-handed Watson-Crick double helix. Z-nucleic acids were discovered more than 40 years ago, but their biological function has remained poorly understood.
A high-end race car engine needs all its components tuned and working together precisely to deliver top-quality performance. The same can be said about the processor inside a quantum computer, whose delicate bits must be adjusted in just the right way before it can perform a calculation. Who's the right mechanic for this quantum tuneup job? According to a team that includes scientists at the National Institute of Standards and Technology (NIST), it's an artificial intelligence, that's who.
WASHINGTON--Thyroid hormone replacement therapy in older adults is associated with a higher risk of death compared with no treatment, a large study finds. The study results were accepted for presentation at ENDO 2020, the Endocrine Society's annual meeting, and publication in a special supplemental section of the Journal of the Endocrine Society.
WASHINGTON--Adults who work long hours are more likely to have hypothyroidism, which is an underactive thyroid, according to study results accepted for presentation at ENDO 2020, the Endocrine Society's annual meeting, and publication in a special supplemental section of the Journal of the Endocrine Society.
WASHINGTON--Three in four hypothyroidism patients who chose desiccated thyroid extract (DTE) over the standard therapy said this option was more effective than other thyroid hormone medications, according to an analysis of comments in online patient forums accepted for presentation at ENDO 2020, the Endocrine Society's annual meeting, and publication in a special supplemental section of the Journal of the Endocrine Society.
