A new study of 6,610 human flu sequences predicts that this fall's flu vaccine will likely have the same reduced efficacy against the dominant circulating strain of influenza A as the vaccine given in 2016 and 2017 due to viral mutations related to vaccine production in eggs.
Hematopoietic stem cells (HSCs) are a class of stem cells located in bone marrow. HSCs give rise to every type of blood cell—from the red blood cells that carry oxygen to the white blood cells of the immune system.
Bone marrow provides a niche that both houses and regulates HSCs to ensure proper formation of blood cells. However, the precise mechanisms that maintain the HSC niche are not fully understood.
More sensitive cultivation methods and precise 16S rRNA gene sequencing techniques have revealed that the human bladder hosts a significant microbiome and those diverse bacteria inside the bladder impact pediatric urologic diseases.
Researchers have found the molecular mechanism of the enzyme AsqJ, this will provide new options in the production of pharmaceutically active molecules. Practically all biochemical processes involve enzymes that accelerate chemical reactions.
They protect us from the onslaught of bacteria and viruses and also from cancer: T cells are an indispensable part of our immune system. They constantly renew their surface with thousands of highly sensitive T cell antigen receptors, which allow them to identify atypical or foreign molecules (antigens) in our body. If such antigens are detected, for example on virally infected cells or cancer cells, T cells either directly kill these cells or alarm other immune cells to start a full-blown immune response.
According to a new study, researchers identified that the inactivity of astronauts during spaceflights presents a significant risk to their muscles. Scientists have simulated the impact of 21 day spaceflights on the body, and the impact of low gravity environments such as the Moon or Mars. The study was published in The Journal of Physiology.
Research shows anti-hypertensive drugs improve heart rate more in patients who listen to music after taking medication. Among musical genres, classical music is the one with greatest efficiency at reducing arterial pressure; authors of the study speculate whether music acts on the patients' parasympathetic system, increasing their capability of absorbing medication. The study was published in Scientific Reports.
A new study is examining the blood vessel health of these women during normal estrogen peaks and valleys and seeing whether treatment with over-the-counter supplements can help restore protection. The high estrogen levels that typically afford younger women protection from cardiovascular disease appear to instead multiplyestrogen level their risk if they have type 1 diabetes.
According to a new study, researchers examine the interventions such as speeding enforcement and formal swimming lessons for young children could potentially save more than 250,000 lives a year if they were implemented acryoss populations living in extreme poverty in low- and middle-income countries. The study was published in The Lancet Global Helath.
Patients with kidney failure who are treated with hemodialysis are at substantially increased risk of life-threatening infections, according to the research
This study explained the characteristics of bone biochemical indices, including bone mineral density (BMD), metabolic markers in elderly women with osteoporotic intertrochanteric fracture and their relevance in secondary fracture
According to the study, researchers explained that under the conditions of high spatial resolution and voxelwise data analysis with a homogeneous tissue model, decreases the scan duration of L-[1-11C]leucine PET studies from 90 to 60 min, which has negligible effects on estimates of rates of cerebral protein synthesis (rCPS)
