Sweet screens: A high-throughput screening platform for identification of inhibitors of sialyl- and fucosyltransferases based on fluorescence polarization (FP) has been developed. An analogue of the natural donor substrate carrying a fluorescent label (green star) is transferred to a glycoprotein acceptor, which results in robust FP. The screening of 16,000 compounds against different glycosyltransferases has identified various interesting inhibitors.

The global rise of mosquito-borne diseases and widespread resistance to existing insecticides highlight the urgent need for novel, field-relevant mosquitocides. Here, we report the development and validation of a high-throughput, in vivo screening assay capable of evaluating adult mosquito toxicity across large chemical libraries. Utilizing a 96-well plate format, this assay enables simultaneous testing of hundreds of compounds per run using both net and filter paper substrates, with direct measurement of adult mosquito knockdown and mortality via tarsal contact - an exposure route highly relevant to real-world vector control tools such as long-lasting insecticide-treated nets (LLINs) and indoor residual spraying (IRS).

Recombinant proteins have been widely applied in the food, biomedical, and scientific fields. Prokaryotic expression systems are preferred platforms for recombinant protein production due to their rapid growth and high protein yields. Nevertheless, disparities between recombinant expression environment and native physiological conditions frequently result in protein misfolding, leading to aggregation into non-functional inclusion bodies or proteolytic degradation.

Di-(2-ethylhexyl)-phthalate (DEHP) is a persistent environmental endocrine toxicant present in many products, and liver is the main target organ for DEHP metabolism. Long-term exposure to DEHP induces hepatic fibrosis, which is reversible in the early stages, while progresses to cirrhosis without timely intervention. Ductular reaction (DR) is a characteristic pathological change in hepatobiliary diseases, however, the involvement of DR in DEHP-caused hepatic fibrosis, the underlying molecular mechanisms, remail largely uninvestigated.

Background: Endometriosis diagnosis is challenging due to non-specific symptoms that overlap with other gynaecological conditions. This study proposes a non-invasive Machine Learning (ML) ‒ based urine test using Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR) spectroscopy for rapid, high-throughput screening.
Methods: A total of 302 symptomatic patients presenting with pelvic pain and MRI referral indications were recruited.

Tilorone, a 9-fluorenone scaffold-based molecule, is a known broad-spectrum antiviral with an IC of 180 nM against SARS-CoV-2, but its mechanism is not known. In the present study, we found it to have weak activity against PLpro (IC = 30.7 ± 7.
