According to the study, researchers estimated exactly that Ras proteins interact with cell membrane surfaces. Protein systems make up the complex signaling pathways that control whether a cell divide or, in some cases, metastasizes. Ras proteins have long been the focus of cancer research because of their role as 'on/off switch' signaling pathways that control cell division and failure to die like healthy cells do.
All news from Anaesthesiology
In a new study published in the JAMA, researchers have shown that women should not undergo screening for ovarian cancer if they do not have signs or symptoms of the disease, as it does not improve survival but may expose women unnecessarily to surgical complications.
According to a new study from the University of Waterloo, elementary school children who read below grade level may have challenges with their eyesight even if standard tests show they see 20/20.
In this study, researchers examine that anesthesia operates in the brain, but the standard protocol among anesthesiologists when monitoring and dosing patients during surgery is to rely on indirect signs of arousal like movement, and changes in heart rate and blood pressure. The study is published in the Proceedings of the National Academy of Sciences.
The study evaluated two once-weekly GLP-1R agonists, semaglutide and dulaglutide, at both low and high approved doses, in about 1,200 patients with type 2 diabetes not well controlled with metformin. With more evidence of variability in efficacy and tolerability of agents in the long-acting glucagon-like peptide-1 receptor (GLP-1R) agonist class of diabetes medicines. The study is been published in The Lancet Diabetes & Endocrinology.
The primary goal of red blood cell (RBC) transfusion is to supply oxygen to tissues and organs. However, due to a growing number of studies that have reported negative transfusion outcomes, including reduced blood perfusion, there is rising concern about the risks in blood transfusion.
Rates of false positive breast cancer screening exams fell significantly after complete integration of diagnostic digital breast tomosynthesis, potentially leading to higher quality, lower costs, and fewer unnecessary biopsies, according to a study to be presented at the ARRS 2018 Annual Meeting, set for April 22-27 in Washington, DC.
In this study, researchers invented for the first time, that the immune cells called macrophages contribute to a type of heart failure for which there currently is no effective treatment. They defines finding how macrophage activity leads to the development of heart failure with preserved ejection fraction (HFpEF) in mouse models of the condition, which accounts for around half of all human heart failure cases. The study published in the Journal of Experimental Medicine.
In this study, researchers assessed the anatomical network analysis of primate head and neck musculoskeletal system. Network theory is increasingly being used to study morphological modularity and integration. Anatomical network analysis (AnNA) is a framework for quantitatively characterizing the topological organization of anatomical structures and providing an operational way to compare structural integration and modularity.
According to this study, researchers identified four viruses that can produce insulin-like hormones that are active on human cells. Every cell in your body responds to the hormone insulin, and if that process starts to fail, they get diabetes. The discovery brings new possibilities for revealing biological mechanisms that may cause diabetes or cancer. The study published in the journal PNAS.
