Keeping out COVID-19 in Newfoundland

When is it the right time to reopen borders? Is it when there are no more local cases? A new study published on the preprint server medRxiv in July 2020 shows that travel restrictions are highly effective in preventing future outbreaks.

A new method for mechanical stimulation of neural cells

In addition to responding to electrical and chemical stimuli, many of the body's neural cells can also respond to mechanical effects, such as pressure or vibration.

Age-related hearing loss mainly caused by damage to hair cells, study shows

In a new study of human ear tissues, hearing scientists have demonstrated that age-related hearing loss, also called presbycusis, is mainly caused by damage to hair cells, the sensory cells in the inner ear that transform sound-induced vibrations into the electrical signals that are relayed to the brain by the auditory nerve.

Premature babies are exposed to high noise levels in the incubator, shows study

What do premature babies hear while lying in an incubator? That is the question addressed by an interdisciplinary team from the Medical University of Vienna, led by Vito Giordano (neuroscientist at the Division of Neonatology, Pediatric Intensive Care and Neuropediatrics at the Comprehensive Center for Pediatrics (CCP) of Medical University of Vienna) and by music physiologist Matthias Bertsch from the University of Music and the Performing Arts in the recent study "The Sound of Silence", published in the journal "Frontiers in Psychology".

Developing a Better Understanding of Polycystic Ovary Syndrome (PCOS)

In this interview, Dr. Andrea Dunaif talks to News-Medical about their genetic analysis study which suggests there are different subtypes of PCOS.

Findings show promise for developing vaccines against multiple strains of flu, including SARS-CoV-2

A vaccine additive known as an adjuvant can enhance responses to a vaccine containing the exotic avian flu virus H5N1, so that both rookie and veteran elements of the immune response are strengthened, according to results from an Emory Vaccine Center study.

COVID-19 associated with serious blood clots in leg arteries

COVID-19 is associated with life-threatening blood clots in the arteries of the legs, according to a study published in Radiology.

Likelihood of SARS-CoV-2 transmission may depend on blood type of spreader and recipient

A modeling study by Dr. Peter Ellis from the University of Kent indicates that ABO incompatibility between infected patients and susceptible individuals may actually decrease the transmissibility of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by 60% or more. His detailed investigation of such "ABO-interference" can be found on the medRxiv preprint server.

Most New Zealanders stockpile large quantities of paracetamol in their homes, study shows

While paracetamol was the most common substance of enquiry for calls to the National Poisons Centre in 2018, new research reveals most New Zealanders have large quantities of the painkiller stockpiled in their homes.

Transmission of coronavirus from dogs to humans is scientifically flawed

A study published earlier this year claiming the coronavirus may have jumped from dogs to humans is scientifically flawed, offering no direct evidence to support its conclusions, according to a collaborative group of international researchers, including scientists at the University of Colorado Anschutz Medical Campus.

Mobility and flexibility in SARS-CoV-2 proteins

Now, a new study published on the preprint server bioRxiv in July 2020 describes the use of in silico modeling of potential drug targets on the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) protein structures, using data retrieved from the Protein Databank (PDB).

New link between impaired brain energy metabolism and delirium discovered

Scientists from Trinity College Dublin have discovered a new link between impaired brain energy metabolism and delirium - a disorienting and distressing disorder particularly common in the elderly and one that is currently occurring in a large proportion of patients hospitalized with COVID-19.

A new measles-based COVID-19 vaccine

Now, a new study by researchers from Germany's Paul Ehrlich Institute and published on the preprint server bioRxiv in July 2020 describes a potential vaccine based on the measles vaccine, which elicits both an antibody response and cellular immunity against the virus. This also protects against the measles virus. This could be a significant weapon in the fight against these two threats.

Bird poop may harbor abundant antibiotic resistance genes

Bird poop may pose more health risks than people realize, according to Rice University environmental engineers who study antibiotic resistance.

Single dose of flu drug can prevent influenza spread among household contacts

A single dose of the flu drug baloxavir marboxil can reduce the spread of the illness within households, new research concludes.

Preserving people's health is as important as reviving the economy during COVID-19, argue researchers

Strategies for the safe reopening of low and middle-income countries (LMICs) from months of strict social distancing in response to the ongoing COVID-19 pandemic must recognize that preserving people's health is as important as reviving the economy, argue an international team of researchers.

Newly identified gene variants in Black Americans could lead to precision prostate cancer therapies

Black men in the United States are known to suffer disproportionately from prostate cancer, but few studies have investigated whether genetic differences in prostate tumors could have anything to do with these health disparities.

Study sheds new light on neurobiological processes that control drug-related adaptations

The lab of Jeremy Day, Ph.D., at the University of Alabama at Birmingham, has used single-nucleus RNA sequencing approaches to compare transcriptional responses to acute cocaine in 16 unique cell populations from a portion of the brain called the nucleus accumbens, or NAc.

Researchers map RNA structure throughout SARS-CoV-2 genome

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which is currently at the heart of a pandemic that has cost the world more than 550,000 lives, 12 million infections, and uncounted years of productivity, is an RNA virus with the largest genome among all such viruses. This 30 kb size virus has caused many difficulties for scientists in search of a vaccine.
