A University of Manchester team has applied new techniques to detect and track the transmission of Covid-19 in hospital. The proof of concept system combines the movement and interaction of staff and patients with genomic sequencing of the virus, helping to signpost how best to improve patient pathways, staff movement and reduce risk. They identified hotspots within hospitals where patients and…
Recovery duration, co-morbidities, mortality, risk groups: A large UK study reports in detail on 'Long Covid'. We spoke with two of the study's co-investigators about why so many patients are still affected after a coronavirus infection.
An innovative hydrogel – called a double network (DN) gel – can rapidly reprogram differentiated cancer cells into cancer stem cells, researchers at Hokkaido University and the National Cancer Center Research Institute have reported in the journal Nature Biomedical Engineering. The hydrogel can be used to help develop new cancer therapies and personalized medicines targeting cancer stem cells.
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.
Using an ordinary light microscope, engineers at the Massachusetts Institute of Technology (MIT) have devised a technique for imaging biological samples with accuracy at the scale of 10 nanometers — which should enable them to image viruses and potentially even single biomolecules, the researchers say. The new technique builds on expansion microscopy, an approach that involves embedding…
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 are developing a COVID-19 vaccine that could provide protection against both existing and future strains of the COVID-19 virus, and other coronaviruses, and cost about $1 a dose has shown promising results in early animal testing.
Researchers have developed an innovative method to disrupt the formation of biofilms and thus facilitate the treatment of infections with Pseudomonas aeruginosa.
Researchers investigated whether the vaccine recipients developing unusual thrombotic events and thrombocytopenia could have a prothrombotic disorder caused by platelet-activating antibodies directed against a platelet protein, as a similar mechanism is known to be caused by heparin and sometimes other environmental triggers.
Due to their tissue-like mechanical properties, hydrogels are being increasingly used for biomedical applications; a well-known example are soft contact lenses. These gel-like polymers consist of 90 percent water, are elastic and particularly biocompatible. Hydrogels that are also electrically conductive allow additional fields of application, for example in the transmission of electrical signals…
A study conducted by Columbia University Mailman School of Public Health researchers reports a high global prevalence of both depression and anxiety during the Covid-19 pandemic. It also shows how the implementation of mitigation strategies including public transportation and school closures, and stay-at-home orders impacted such disorders. Results are published in Psychological Medicine.
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.
In what is believed to be the first published study of Covid-19 vaccine effectiveness in long-term care facilities such as nursing homes, a research team co-led by the Yale School of Public Health found a widely used vaccine is highly successful in preventing infections. Residents of such facilities, particularly those in skilled nursing facilities (SNFs), have experienced disproportionately high…
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…
It is possible to identify Parkinson’s Disease based on compounds found on the surface of skin, according to new research. The findings offer hope that a pioneering new test could be developed to diagnose the degenerative condition through a simple and painless skin swab. Scientists at The University of Manchester have developed a technique which works by analysing compounds found in sebum -…
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…
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…
