In this study, researchers have found the stress of open-heart surgery significantly reduces patients' vitamin D levels, but aggressive supplementation with vitamin D3, just before and after surgery, can completely eliminate the observed drop in vitamin D. They conducted a study called ASSESS-D, in which they discovered two key findings related to vitamin D levels and open-heart surgery.
Scientists at Southern Research are investigating how a mutated protein associated with prostate cancer plays a role in the development of the disease and whether it holds a key to better treatment outcomes. The study findings could lead to a new therapeutic target or a biomarker that predicts whether or not a certain course of treatment would benefit patients.
In this study, researchers aim to explore the prevalence statistics on low birth weight(LBW) and analyze socioeconomic, demographic and health factors related to LBW in the population of Bangladesh based on a sub-sample from a nationally representative data. Additionally, they aim to assess the nation’s progress towards SDGs from this sub-study.
This study provides a measure of the success of public health policy and interventions, and at a broad level aims to help shape future approaches to reducing the prevalence of LBW.
In this study, researchers have invented a new existing microscopy methods to explore living brain tissue have been limited to imaging previously labelled cells. Microscopy is a basic tool in research into the biology of any organism given that the elements studied, the cells, are of microscopic and frequently nanoscopic size. The study was published in the scientific journal Cell.
The U.S. Food and Drug Administration (FDA) has issued a letter to healthcare providers warning them that neurovascular embolization coils containing 304V stainless steel may increase image artifact when magnetic resonance angiography imaging is used to image a patient’s aneurysm after coiling.
Higher concentrations of a marker of inflammation in three regions of the brain suggest untreated major depression, particularly when such concentrations persist for longer than 10 years, a new imaging study shows. The study is published in the Lancet Psychiatry.
According to a new study, researchers have invented a novel mechanism that is employed by humans to estimate their relative distance from sound sources. The ability to estimate distances to sound sources accurately can be crucial for survival. The investigation reveals that humans can perform this task more efficiently when they are allowed to move. The study was published in the Proceedings of the National Academy of Sciences (PNAS).
In this study, researchers examined eczema affects about 17% of children in developed countries and is often the gateway to food allergy and asthma, initiating an "atopic march" toward broader allergic sensitization. There are treatments, steroid creams, and a recently approved biologic, but they are expensive or have side effects. The study was published in Science Immunology.
HIV, the virus that causes AIDS, has a secret life. Though antiretroviral therapy can reduce its numbers, the virus can hide and avoid both treatments and the body's immune response.
A new study reveals that acupuncture is a safe alternative to drugs and is under-researched because of a lack of commercial interest, while another study found no convincing evidence of clinical benefit and potential risks of the procedure. So should doctors recommend acupuncture for pain? Experts debate the issue in The BMJ.
The study evaluates the genetic defects of ciliary genes causing the loss of primary cilium in autosomal dominant polycystic (ADPKD). Autosomal dominant polycystic kidney disease (ADPKD) is a multisystem disorder characterized by the formation of cysts in the kidneys and other organs. ADPKD affects more than 12.5 million people worldwide.
Approximately 50% of patients with ADPKD have the end-stage renal disease (ESRD) by 60 years of age. Dialysis and kidney transplantation are the only treatment options for patients with ESRD. The reason for the absence of targeted treatment is insufficient understanding of the molecular mechanism of cystogenesis. The primary cilium is a signaling organelle that extends from the surface of the plasma membrane of most mammalian cells.
