Heidelberg [Germany], August 19 (ANI): The cell of origin of mixed liver/biliary duct carcinomas, a rare type of liver cancer, has been found in mice by researchers from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) and the Hebrew University in Jerusalem. Carcinogenesis has been linked to the pro-inflammatory immunological messenger interleukin 6 (IL-6). In mice, blocking IL-6 lowered the number and size of tumours.
Washington [US], August 19 (ANI): Alzheimer's disease affects at least one type of visual memory by deteriorating a recently found circuit that connects the image processing areas of each brain hemisphere, according to a new MIT study.
Washington [US], August 19 (ANI): A team has uncovered surprising mechanical behaviors of the nucleus. For years, the nucleus within a cell was thought to be elastic like a rubber ball, deforming and snapping back into shape as the cell navigated through pores and between fibers inside the human body. Researchers have now discovered that the nucleus is more complex than originally believed, behaving more like a liquid drop than a rubber ball.
New Delhi [India], August 18 (ANI): The cumulative number of Covid-19 vaccine doses administered in the country crossed the 208.95 crore mark on Thursday, with over 12 crore precaution doses administered till 7 am on August 18.
Washington [US], August 18 (ANI): With antibiotic-resistant bacteria on the rise, scientists have been searching for ways to shut down the Type IV secretion system (T4SS), a protein complex on the outer envelope of bacterial cells that helps them to exchange DNA with neighbouring bacteria and resist antibiotics.
Washington [US], August 17 (ANI): Cancer-associated fibroblasts in the tumour environment have typically been associated with tumour progression and resistance to therapy, despite some studies suggesting that these fibroblasts may also sensitize cancer cells to therapy.
Washington [US], August 17 (ANI): Researchers have made a surprising discovery linking Delta/Notch signalling in subperineurial glia (SPG) to the regulation of nerve ensheathment and neurotransmitter release at the Drosophila neuromuscular junction (NMJ). SPG, the counterpart of the endothelial layer in the vertebrate blood-brain barrier, form the key cellular layer that is critical for axonal ensheathment and the blood-brain barrier in Drosophila. The results provide mechanistic insight into the biology of barrier function and glia-neuron interactions.
Washington [US], August 17 (ANI): New research indicates a little bit of daily activity is more beneficial than longer periods of exercise spread out across the week and happily, it also suggests you don't have to put in a mountain of work every day.
Washington [US], August 16 (ANI): Scientists at the Salk Institute have discovered a biochemical route that combines hazardous sights, sounds, and odours into a single message: Be afraid. CGRP is a protein that allows neurons in two different parts of the brain to combine hazardous sensory cues into a cohesive signal, label it as negative, and send it to the amygdala, which converts the information into fear.
Washington [US], August 16 (ANI): A new UC Davis Health study has found that paediatric kidney transplant patients have better long-term outcomes when their kidney comes from living, biologically unrelated donors compared to deceased donors.
Washington [US], August 15 (ANI): Cancer cell metabolism has been perceived as somewhat of a conundrum for more than a century. Recent findings from Washington University in St. Louis academics suggest that it might not be an abnormality at all. The work was released in Molecular Cell on August 15.
Georgia [US], August 15 (ANI): According to a recent animal study, testosterone can encourage males to be sociable and friendlier. The results of neuroscientists at Emory University's study on Mongolian gerbils were published in the Proceedings of the Royal Society B.
Seoul [South Korea], August 15 (ANI): An international research team has succeeded in recovering muscle movement in a model of paralysed mice organic through artificial nerves. The team was led by Prof. Tae-Woo Lee (Department of Materials Science and Engineering, Seoul National University, Republic of Korea) and Prof. Zhenan Bao (Department of Chemical Engineering, Stanford University, US).
Pennsylvania [United States], August 15 (ANI): Cancer-related fatigue (CRF) is a lasting side effect for many women who have had chemotherapy for breast cancer, and it contributes to ongoing balance issues.
Lexington [Kentucky], August 15 (ANI): According to a recent study from the University of Kentucky Markey Cancer Center, the common steroid betamethasone may be utilised to lessen the negative effects of radiation therapy for prostate cancer.
Washington [US], August 14 (ANI): In order to save a life, unnatural, direct connections between arteries and veins are made, such as a kidney dialysis access point or using a vein to get around a coronary artery blockage.
Washington [US], August 14 (ANI): According to a new study, the gene defect underlying Krabbe disease causes degeneration of neurons directly, independent of its effects on other cell types. The discovery represents a new mechanism of action for the mutant gene, presenting a more accurate picture of the disease process that may help in the development of therapies.
Washington [US], August 14 (ANI): The findings of a recent study suggest that dietary salt substitutes lower the risk of heart attack, stroke, and death from all causes and cardiovascular disease, finds a pooled data analysis of the available evidence.
