Effectiveness of vitamin C against COVID-19 depends on its natural transporter levels

High doses of vitamin C under study for treating COVID-19 may benefit some populations, but investigators exploring its potential in aging say key factors in effectiveness include levels of the natural transporter needed to get the vitamin inside cells.

Research on autophagy and coronavirus, implicates ULK1

Researchers from the University of British Columbia have discovered that the betacoronavirus-encoded papain-like protease disrupts autophagy, partly by targeting ULK1. Their work is reported on the preprint server bioRxiv* in October 2020.

Early life exposure to air pollution may increase children's body mass index

Exposure to higher air pollution levels and greater population density during the early months of life may be associated with an increase in children's body mass index (BMI).

About 15% of COVID-19-related deaths linked to long-term exposure to air pollution

Long-term exposure to air pollution has been linked to an increased risk of dying from COVID-19 and, for the first time, a study has estimated the proportion of deaths from the coronavirus that could be attributed to the exacerbating effects of air pollution for every country in the world.

Researchers show a simple way to protect transplanted islets from rejection

Type 1 diabetes, or T1D, results from the autoimmune destruction of the insulin-producing cells of the pancreas. People with T1D require exogenous insulin and suffer swings in the levels of glucose in the blood that impact life expectancy and increase risks of cardiovascular disease, neuropathies and kidney failure.

Glutathione precursor improves multiple deficits associated with premature aging

Premature aging in people with HIV is now recognized as a new, significant public health challenge. Accumulating evidence shows that people with HIV who are between 45 to 60 years old develop characteristics typically observed in people without HIV that are more than 70 years of age.

Genomic analysis of neuroblastoma sheds light on childhood solid tumors

Researchers have used insight from a comprehensive genomic analysis of neuroblastoma to learn about the process driving one of the most common childhood solid tumors. The findings revealed possible approaches for developing precision medicines to improve patient outcomes. St. Jude Children's Research Hospital scientists led the study, which appears today in the journal Nature Communications.
