Flumequine, a fluoroquinolone in disguise.

Fluoroquinolone resistance in E. coli isolates from livestock in Europe remains high despite EMA restrictions on fluoroquinolone use in animals. However, flumequine, a quinolone not classified as a fluoroquinolone by various regulatory bodies, is still used in livestock in the Netherlands, Belgium, Greece and France.

Substrate adaptors are flexible tethering modules that enhance substrate methylation by the arginine methyltransferase PRMT5.

Protein arginine methyltransferase (PRMT) 5 is an essential arginine methyltransferase responsible for the majority of cellular symmetric dimethyl-arginine (SDMA) marks. PRMT5 uses substrate adaptors such as pICln, RIOK1, and COPR5, to recruit and methylate a wide range of substrates. Although the substrate adaptors play important roles in substrate recognition, how they direct PRMT5 activity towards specific substrates remains incompletely understood.

Efficacy of a vein visualisation device for facilitating peripheral venous line placement in adult patients with sickle cell disease: A randomised clinical trial.

Background: Intravenous (IV) access is often required for the treatment of vaso-occlusive crises in patients with sickle cell disease, but can be particularly challenging due to recurrent venous damage. The AccuVein® device, uses near-infrared light technology to visualise veins for easier venepuncture.

Methods: A randomised, controlled trial of the efficacy of the AccuVeinAV400® device in the replacement of peripheral venous lines during a vaso-occlusive crisis was conducted at two centres in France.

Chemical cues of conspecific predation elicit distinct behavioural responses in cannibalistic poison frog tadpoles.

In cannibalistic species, conspecifics can be both predators and prey. As a result, conspecifics present a unique conflict at the intersection of predation, competition and nutritional resources in these species. To better understand how individuals respond to the complex information of conspecific chemical cues, we studied aggressive and cannibalistic tadpoles of the dyeing poison frog, .

Solar energy resource availability under extreme and historical wildfire smoke conditions.

By 2050, the U.S. plans to increase solar energy from 3% to 45% of the nation's electricity generation.
