Study investigates link between lactation and visceral, pericardial fat

Thu, 2021-04-08 21:00
(Texas Tech University Health Sciences Center) As demonstrated by multiple studies, women who breastfeed have a lower risk for developing cardiovascular disease and diabetes, though the mechanisms by which these risks are reduced for lactating women are still not fully understood. Duke Appiah, Ph.D., from the Texas Tech University Health Sciences Center and a team of collaborators recently completed a study to see if the presence of excess fat, specifically visceral and pericardial fat, could help explain this finding.

Balancing between build-up and break-down of bone

Thu, 2021-04-08 21:00
(Osaka University) Researchers at Osaka University have shown that SLPI, a secretory leukocyte protease inhibitor, coordinates the mutually contradictory actions of parathyroid hormone (PTH) on bone. They revealed the genetic mechanisms and molecular pathways whereby SLPI promotes osteoblast activity to augment bone mass and showed how osteoblasts interact with osteoclasts to subdue bone resorption. This knowledge will inform clinical usage of anabolic PTH in osteoporosis as well as promote development of innovative drugs.

New pig brain maps facilitate human neuroscience discoveries

Wed, 2021-04-07 21:00
(University of Illinois College of Agricultural, Consumer and Environmental Sciences) For nearly a decade, scientists have relied on an MRI-based map, or atlas, of the pig brain - developed at the University of Illinois using 4-week-old pigs - to understand where and how nutrients and other interventions affect the developing brain. Now, Illinois scientists have updated that atlas, increasing its resolution by a factor of four, and they have also added a new atlas for adolescent 12-week-old pigs.

COVID-19 causes 'unexpected' cellular response in the lungs, research finds

Wed, 2021-04-07 21:00
(Purdue University) Scientists have discovered a surprising response in lung cells infected with the SARS-CoV-2 virus, which might explain why the disease is so difficult to treat. "This was completely unexpected," says Purdue scientist Majid Kazemian, who led the research. The researchers suggest testing a new pairing of drugs to combat the disease.

Leaking calcium in neurons an early sign of Alzheimer's pathology

Wed, 2021-04-07 21:00
(Yale University) Leaking calcium in neurons an early sign of Alzheimer's pathologyNew Haven, Conn. -- Alzheimer's disease is known for its slow attack on neurons crucial to memory and cognition. But why are these particular neurons in aging brains so susceptible to the disease's ravages, while others remain resilient?

Accelerated cellular aging associated with mortality seen in depressed individuals

Wed, 2021-04-07 21:00
(Walter Reed Army Institute of Research) Cells from healthy individuals with major depressive disorder were found to have higher than expected rates of methylation at specific sites on their DNA, when compared to cells from healthy individuals without MDD, according to a study by a multidisciplinary team. Moving forward, the researchers hope to determine whether pharmacological treatments or therapy may mitigate some methylation changes related to MDD in hopes of normalizing the cellular aging process in affected individuals before it advances.

The tuberculosis pathogen releases its toxin by a novel protein transport system

Wed, 2021-04-07 21:00
(University of Alabama at Birmingham) Six years ago, Michael Niederweis, Ph.D., described the first toxin ever found for the deadly pathogen Mycobacterium tuberculosis. However, the mechanism for its secretion from the bacterium was unknown. Now, researchers describe two small Esx proteins that form pores in bacterial membranes and are essential for toxin release. This transport system may be widespread across many Gram-positive bacteria that contain proteins in the WXG100 superfamily.

New method offers insights into tension-sensitivity of potassium channels

Wed, 2021-04-07 21:00
(University of Fukui) Ion channel activity varies according to the mechanical stresses acting on ion channels within the cell membrane, but directly measuring such changes within a complex cell membrane is difficult. Now, researchers at the University of Fukui have developed a simplified model system that allows experimenters to measure both membrane tension and the associated variability in ion channel activity. Their experiments have already yielded evidence for hysteresis in a potassium channel's responses to membrane tension.

Huntsman Cancer Institute research shows melanoma rates in Utah compared to

Wed, 2021-04-07 21:00
(Huntsman Cancer Institute) Utah had more melanoma deaths than any other state from 1975 to 2013, says a letter published today by HCI researchers in the New England Journal of Medicine. In contrast to the rest of the United States, melanoma mortality in Utah increased by 0.8% per year over that period. The researchers say this data emphasizes the need to stay vigilant about preventing melanoma.
