Comparing machine learning screening approaches using clinical data and cytokine profiles for COVID-19 in resource-limited and resource-abundant settings.

Accurate screening of COVID-19 infection status for symptomatic patients is a critical public health task. Although molecular and antigen tests now exist for COVID-19, in resource-limited settings, screening tests are often not available. Furthermore, during the early stages of the pandemic tests were not available in any capacity.

Genetic Mapping and Discovery of the Candidate Gene for Black Seed Coat Color in Watermelon ().

Seed coat color is an important trait highly affecting the seed quality and flesh appearance of watermelon (). However, the molecular regulation mechanism of seed coat color in watermelon is still unclear. In the present study, genetic analysis was performed by evaluating F, F and BC populations derived from two parental lines (9904 with light yellow seeds and Handel with black seeds), suggesting that a single dominant gene controls the black seed coat.

Gallbladder perforation: case series and systematic review.

Background: Gallbladder perforation is a serious complication of acute cholecystitis. Its management has evolved considerably since its classification by Niemeier in 1934. This review summarises the evidence surrounding the natural progression of this condition and potential problems with Niemeier's classification, and proposes a management algorithm for the more complex type II perforation.
