Portable biosensor for the detection of Enrofloxacin and Ciprofloxacin antibiotic residues in food, body fluids, environmental and wastewater samples
Biosens Bioelectron. 2023 Jun 14;237:115478. doi: 10.1016/j.bios.2023.115478. Online ahead of print.ABSTRACTEnrofloxacin (ENR) and its metabolite Ciprofloxacin (CIP) are both a class of fluoroquinolone antibiotics effective against a broad-spectrum microbial infection. Recent surge in the consumption of CIP and ENR has been linked to increased cases of drug-resistant pathogens. This is due to the fact that the antibiotic residues remain in milk, meat, soil and environmental water for a prolonged duration. Although gold standard methods such as LC-MS are sensitive, they suffer from expensive operation and maintenance cost, ...

Mammary basal cells: Stars of the show
Biochim Biophys Acta Mol Cell Res. 2021 Oct 12:119159. doi: 10.1016/j.bbamcr.2021.119159. Online ahead of print.ABSTRACTNearly all mammals rely on lactation to support their young and to ensure the continued survival of their species. Despite its importance, relatively little is known about how milk is produced and how it is ejected from the lumen of mammary alveoli and ducts. This review focuses on the latter. We discuss how a relatively small number of basal cells, wrapping around each alveolar unit, contract to forcibly expel milk from the alveolar lumen. We consider how individual basal cells coordinate their activity,...

All Your Coronavirus Questions, Answered
One of the worst symptoms of any plague is uncertainty—who it will strike, when it will end, why it began. Merely understanding a pandemic does not stop it, but an informed public can help curb its impact and slow its spread. It can also provide a certain ease of mind in a decidedly uneasy time. Here are some of the most frequently asked questions about the COVID-19 pandemic from TIME’s readers, along with the best and most current answers science can provide. A note about our sourcing: While there are many, many studies underway investigating COVID-19 and SARS-CoV-19, the novel coronavirus that causes the illn...
