A potential at-home COVID-19 test is just as good as laboratory PCR tests, according to preclinical data

Researchers have developed an at-home COVID-19 test with a high-quality assay that can detect the virus with similar reliability to laboratory-based molecular tests. The new test uses loop-mediated isothermal amplification and has unique advantages, such as speed and direct detection of viral RNA in saliva.

Mild autonomous cortisol secretion predominantly affects women, associated with risk for hypertension, diabetes

A cross-sectional study found that mild autonomous cortisol secretion (MACS) predominantly affects women, increasing the frequency and severity of hypertension and type 2 diabetes compared to nonfunctioning adrenal tumors. Patients with MACS carried an increased cardiometabolic burden similar to Cushing Syndrome, even without typical f...

All in a day’s work

Researchers compared the energetic strategies of humans and great apes, finding that humans are less efficient at acquiring food due to their high-intensity activities. However, this inefficiency is compensated by a higher return rate on energy investment, making human subsistence strategies successful.

New journal of Pharmaceutical Analysis study shows novel strategy to improve quality checking of generic drugs

Researchers devised a novel approach to unify quality assessment of generic drugs developed through different processes. The 'population pharmaceutical quality assessment' method uses computational modeling to evaluate process information, providing a scientific tool for objective quality consistency evaluation.
