SARS-CoV-2 viable 21 days in blood, mucus, semen, urine, but just 24 hours in breast milk

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes the coronavirus disease (COVID-19), spreads through respiratory droplets and aerosols expelled when infected individuals cough, sneeze, breathe or sing.

Psychedelic drugs may work in multiple ways in the brain

University of Maryland School of Medicine (UMSOM) researchers have shown that psilocybin—the active chemical in “magic mushrooms”— still works its antidepressant-like actions, at least in mice, even when the psychedelic experience is blocked.

PCR-based reverse genetic system helps analyze SARS-CoV-2 mutations

SARS-CoV-2 is the virus responsible for the COVID-19 pandemic. We know that mutations in the genome of SARS-CoV-2 have occurred and spread, but what effect do those mutations have?

People who experience big dips in blood sugar levels consume more calories

New research shows that people who experience big dips in blood sugar levels, several hours after eating, end up feeling hungrier and consuming hundreds more calories during the day than others.

Adequate levels of antioxidants may reduce HPV infection linked to cervical cancer development

A study led by Hui-Yi Lin, Ph.D., Professor of Biostatistics, and a team of researchers at LSU Health New Orleans Schools of Public Health and Medicine has found that adequate levels of five antioxidants may reduce infection with the strains of the human papillomavirus (HPV) associated with cervical cancer development.

Monitoring CO2 to assess risk of indoor airborne SARS-CoV-2 transmission

In the study, which appeared on the pre-print server medRxiv, the team developed a general mathematical theory to predict airborne transmission risk from carbon dioxide (CO2) time series in real-time and clarify different estimates that steer the guideline. The study findings were based on the assessment of transmission risk and implementing the guideline by CO2 monitoring in university classrooms and office spaces.

New algorithm can predict which genes cause cancer

A new algorithm can predict which genes cause cancer, even if their DNA sequence is not changed. A team of researchers in Berlin combined a wide variety of data, analyzed it with "Artificial Intelligence" and identified numerous cancer genes.

Experts review new studies on cardiovascular effects of cigarette smoking versus electronic cigarettes

Electronic cigarette (EC) use, or vaping, has both gained incredible popularity and generated tremendous controversy, but although they may be less harmful than tobacco cigarettes (TCs), they have major potential risks that may be underestimated by health authorities, the public, and medical professionals.

CityMD experience during the coronavirus pandemic in New York City

Limiting SARS-CoV-2 transmission requires an infected person to quarantine themselves for at least two weeks. New research published on the medRxiv* server highlights the vital role urgent care centers play during the COVID-19 pandemic in New York.

Researchers identify new potential mechanism for age-related macular degeneration

Using laboratory-grown roundworms as well as human and mouse eye tissue, University of Maryland School of Medicine (UMSOM) researchers have identified a new potential mechanism for age-related macular degeneration - the leading cause of blindness among older adults.

Inhibition of nsp14 methyltransferase as a potential antiviral target for SARS-CoV-2

Beyond vaccination, the broad-spectrum antiviral medication remdesivir has robust clinical evidence and is known as the best antiviral treatment to reduce severe COVID-19 infection in hospitalized patients. Research led by John F.X. Diffley of the Chromosome Replication Laboratory suggests a potential therapeutic target for treatment development is the viral RNA cap methyltransferases, essential for viral protein translation and immune evasion.

New technology shows encouraging results for treating osteosarcoma

A preclinical study led by researchers at The University of Texas MD Anderson Cancer Center shows an antibody-drug conjugate (ADC) targeting surface protein MT1-MMP can act as a guided missile in eradicating osteosarcoma tumor cells without damaging normal tissues.

Could Zebrafish larvae be a novel animal model for SARS-CoV-2?

Researchers based in Paris, France, have explored the potential use of zebrafish larvae as animal models for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). These larvae are small and cheap, so could prove a suitable medium for rapid mass testing of the disease.

Melanoma mortality is higher in Utah than in any other state, shows report

A letter published today [April 8, 2021] by Huntsman Cancer Institute (HCI) at the University of Utah (U of U) in the New England Journal of Medicine reports that melanoma mortality among Utahns outpaced that of the rest of the United States during the period from 1975 to 2013.

High SARS-CoV-2 vaccine effectiveness in California, even with variants

Researchers in the United States and the UK have conducted a study showing that the rollout of vaccines to protect against coronavirus disease 2019 (COVID-19) is proving effective among California's general population.

Real-world evidence from Israel on VOCs and SARS-CoV-2 vaccine protection

A new study by Israeli researchers tested the hypothesis that certain SARS-CoV-2 variants of concern can overcome protection conferred by Pfizer-BioNTech (BNT162b2) mRNA vaccine and found evidence of increased breakthrough rates in vaccinated individuals. The research paper is currently available on the medRxiv preprint server.
