Electric recycling of Portland cement at scale.

Cement production causes 7.5% of global anthropogenic CO emissions, arising from limestone decarbonation and fossil-fuel combustion. Current decarbonation strategies include substituting Portland clinker with supplementary materials, but these mainly arise in emitting processes, developing alternative binders but none yet promises scale, or adopting carbon capture and storage that still releases some emissions.

LC-MS-Compatible Chromatographic Method for Quantification of Potential Organic Impurities of Elagolix Sodium in Tablet Dosage Form with Identification of Major Degradation Products.

Background: Elagolix is a gonadotropin-releasing hormone (GnRH) modulator and used for pain relief from endometriosis.

Objective: The present research was performed to develop and validate a simple, novel, fast, sensitive, and cost-effective LC-MS-compatible chromatographic method for quantification of all prominent organic impurities of elagolix sodium in tablet formulation with identification of major degradation products.

Methods: The optimum separation of the organic impurities of elagolix sodium was achieved on an ACE C18-PFP (250 mm × 4.

Multiple seropathotypes of verotoxin-producing Escherichia coli (VTEC) disrupt interferon-gamma-induced tyrosine phosphorylation of signal transducer and activator of transcription (Stat)-1.

Verotoxin-producing Escherichia coli (VTEC) O157:H7 inhibits interferon-gamma-stimulated tyrosine phosphorylation of signal transducer and activator of transcription (Stat)-1 in epithelial cells, independent of Verotoxins and the locus of enterocyte effacement pathogenicity island. Although E. coli O157:H7 is the major cause of disease in humans, non-O157:H7 VTEC also cause human disease.
