The first known study to measure SARS-CoV-2 viral load in a variety of organs and tissues may aid our understanding of how Covid-19 develops following infection.
In the largest study of its kind to date, researchers at Massachusetts General Hospital, Brigham and Women’s Hospital and the Ragon Institute of MGH, MIT and Harvard have found the new mRNA Covid-19 vaccines to be highly effective in producing antibodies against the SARS-CoV-2 virus in pregnant and lactating women. They also demonstrated the vaccines confer protective immunity to newborns…
Increased allergic reactions may be tied to the corticotropin-releasing stress hormone (CRH), suggests a new study. These findings may help clarify the mechanism by which CRH induces proliferation of mast cells (MC) – agents involved in the development of allergies in the human nasal cavity.
Alzheimer’s disease seems to progress faster in women than in men. The protein tau accumulates at a higher rate in women, according to research from Lund University in Sweden. The study was recently published in Brain. Over 30 million people suffer from Alzheimer’s disease worldwide, making it the most common form of dementia. Tau and beta-amyloid are two proteins known to aggregate and…
The Institute for Research in Biomedicine (IRB) in Switzerland developed a second-generation ‘double antibody’ that protects from SARS-CoV-2, the virus causing Covid-19, and all its tested variants. It also prevents the virus from mutating to resist the therapy. Antibody-based immunotherapy was already shown to be effective against Covid-19 but faces two main obstacles: it needs to work…
Scientists from Singapore found that antibodies against SARS-CoV-2 wane at different rates, lasting for mere days in some individuals, while remaining present in others for decades. The study, published in The Lancet Microbe, shows that the severity of the infection could be a deciding factor in having longer-lasting antibodies. Individuals with low levels of neutralising antibodies may still be…
Researchers from Cleveland Clinic’s Florida Research and Innovation Center (FRIC) have identified a potential new target for anti-COVID-19 therapies.
A study published by The BMJ sheds light on the risk of infection with SARS-CoV-2 and covid-19 outcomes among adults living with and without children during the first two waves of the UK pandemic. It finds no evidence of any increased risk in wave 1 (Feb to Aug 2020). Small increased risks of infection and hospital admission were seen in wave 2 (Sept to Dec 2020), but this did not translate into…
Electricity may slow – and in some cases, stop – the speed at which breast cancer cells spread through the body, a new study indicates. The research also found that electromagnetic fields might hinder the amount of breast cancer cells that spread. The findings, published recently in the journal Bioelectricity, suggest that electromagnetic fields might be a useful tool in fighting cancers that…
Parkinson’s disease (PD) usually causes facial abnormalities that affect a person’s self-esteem and relationships. However, these abnormalities are difficult to analyze quantitatively with current methods. To address this issue, scientists from Okayama University, Japan, explored whether commercial AI-based facial analysis software could be useful in this context. Their results show that…
The German Center for Neurodegenerative Diseases (DZNE) and Eisai Co., Ltd. announced that both parties have entered into a research collaboration agreement aiming to create potential novel treatments for neurodegenerative disorders including Alzheimer’s disease (AD) which modulate immune competence in neurons and glia cells.
Systematic review finds that machine learning models for detecting and diagnosing Covid-19 from medical images have major flaws and biases, making them unsuitable for use in patients. However, researchers have suggested ways to remedy the problem. Researchers have found that out of the more than 300 Covid-19 machine learning models described in scientific papers in 2020, none of them is suitable…
Do BMMFs, the novel infectious agents found in dairy products and bovine sera, play a role in the development of colorectal cancer? Scientists led by Harald zur Hausen detected the pathogens in colorectal cancer patients in close proximity to tumors. The researchers show that the BMMFs trigger local chronic inflammation, which can cause mutations via activated oxygen molecules and thus promote…
During pandemics, protective behaviors need to be motivated by effective communication. A critical factor in understanding a population’s response to such a threat is the fear it elicits, since fear both contributes to motivating protective responses, but can also lead to panic-driven behaviors. Furthermore, lockdown measures affect well-being, making it important to identify protective factors…
The highly infectious variant of Covid-19 discovered in Kent, which swept across the UK last year before spreading worldwide, is between 30 and 100 per cent more deadly than previous strains, new analysis has shown. A pivotal study, by epidemiologists from the Universities of Exeter and Bristol, has shown that the SARS-CoV-2 variant, B.1.1.7, is associated with a significantly higher mortality…
Hyperpolarized MRI is a recent development and its research and application potential has yet to be fully explored. Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) have now unveiled a new technique for observing metabolic processes in the body. Their singlet-contrast MRI method employs easily-produced parahydrogen to track biochemical processes in…
More human twins are being born than ever before, according to the first comprehensive, global overview published in Human Reproduction, one of the world’s leading reproductive medicine journals. Since the 1980s the twinning rate has increased by a third from 9 to 12 per 1000 deliveries, meaning that about 1.6 million twins are born each year worldwide and one in every 42 children born is a…
Despite Brexit uncertainties, four leading UK cancer research experts expressed optimism for continued pan-European collaboration and innovation during the online panel debate ‘Brexit deal: What it really means for cancer research and innovation’ hosted by the National Cancer Research Institute (NCRI).
A new study carried out by a team of laser physicists, molecular biologists and physicians based at LMU Munich and the Max Planck Institute for Quantum Optics has confirmed the temporal stability of the molecular composition of blood in a population of healthy individuals. The data provide a basis for a new method of monitoring the constituents of blood and detecting alterations that reveal…
When airborne pollen levels are higher, increased SARS-CoV-2 infection rates can be observed. These results were determined by a large-scale study conducted by an international team headed by researchers at the Technical University of Munich (TUM) and the Helmholtz Zentrum München. Members of high-risk groups could protect themselves by watching pollen forecasts and wearing dust filter masks.
Using a nanopore, researchers have demonstrated the potential to reduce the time required for sequencing a glycosaminoglycan — a class of long chain-linked sugar molecules as important to our biology as DNA — from years to minutes. Research to be published this week in the Proceedings of the National Academies of Sciences shows that machine-learning and image recognition software could be…
It is called the "survival protein" because it plays a central role in the growth of cancer cells: survivin influences two important processes in the body's cells at the same time – cell death and cell division. Chemists and biologists at the Universität Duisburg-Essen (UDE) have now succeeded in developing a precise molecule that can bind the protein’s surface at a defined site…
