Enhancing detection of previously missed non-palpable breast carcinomas through artificial intelligence.

Purpose: To investigate the impact of artificial intelligence (AI) reading digital mammograms in increasing the chance of detecting missed breast cancer, by studying the AI- flagged early morphology indictors, overlooked by the radiologist, and correlating them with the missed cancer pathology types.

Methods And Materials: Mammograms done in 2020-2023, presenting breast carcinomas (n = 1998), were analyzed in concordance with the prior one year's result (2019-2022) assumed negative or benign. Present mammograms reviewed for the descriptors: asymmetry, distortion, mass, and microcalcifications.

Development and validation of a new GC-MS method for the detection of tramadol, O-desmethyltramadol, 6-acetylmorphine and morphine in blood, brain, liver and kidney of Wistar rats treated with the combination of heroin and tramadol.

Heroin is one of the most dangerous abused drugs in the world. Tramadol is an additive recently found at high concentration levels in street heroin seizures in Egypt. This substance could affect the usual analytical method for the detection of heroin and metabolites, as well as the pharmacokinetic and disposition of single analytes.

New HPLC method to detect individual opioids (heroin and tramadol) and their metabolites in the blood of rats on combination treatment.

Drug abuse is both an age-old and a constantly evolving problem in society. Trends in illicit drug use are highly fluid, with new formulations increasing in popularity. For this reason, methods for illicit drug detection and analysis need to be continually updated so they remain useful and relevant.

Structural modification of mordenite zeolite with Fe for the photo-degradation of EDTA.

Fe(2+) was incorporated inside mordenite through ion exchange technique in aqueous solution. The amount of Fe loading was 25-100 wt %, using FeSO(4).7H(2)O as precursor and Na-mordenite starting material Na-M.
