is a major foodborne pathogen, and contaminated beef products have been identified as one of the primary sources of -related outbreaks. Pathogenicity and antibiotic resistance of are highly serotype- and subpopulation-specific, which makes it essential to understand high-resolution population dynamics in cattle. Time of year, source of cattle, pen, and sample type(i. Read More

1,4-Oxaborines represent an expansion of the current array of heteroborines. Herein, we report a new ladder-type bis(1,4-oxaborine)pentacene (BO-Pen), the backbone of which can be regarded as an isoelectronic structure of pentacene. The synthesis begins with a two-fold nucleophilic aromatic substitution followed by a ring-closing reaction. Read More

Objective: This work aimed to detect the frequency of pathogenic bacteria of zoonotic importance in ducks' dropping, their surrounding environment, and farmworkers in contact with them. Furthermore, the susceptibility pattern of isolated bacteria to antimicrobial drugs and the efficiency of disinfectants (CID 20, Durak plus, and hydrogen peroxide (HO), nano zinc oxide (ZnO NPs), and hydrogen peroxide loaded nano zinc oxide (HO/ZnO NPs) composites against isolated bacteria were evaluated.

Materials And Methods: A total of samples were collected from duck pens, including 35 fecal droppings, 200 environmental samples, and 36 from the hands of pen workers for isolation and identification of bacterial strains using standard microbiological procedures. Read More

Background: Electronic nicotine delivery systems (ENDSs) are used by some smokers to reduce cigarette consumption, but their effectiveness is uncertain. We aimed to examine the extent to which ENDSs or a non-nicotine cigarette substitute influence tobacco-related toxicant exposure and cigarette consumption in smokers interested in smoking reduction.

Methods: We did a four-arm, parallel-group, randomised controlled trial at two sites in the USA (Penn State University, Hershey, PA, and Virginia Commonwealth University, Richmond, VA). Read More

Protection of healthcare workers (HCWs) against influenza is essential for patient health and a functional health system. The study aimed to analyze the demand for seasonal influenza vaccination (SIV) among various groups of HCWs in a tertiary care hospital before and during the COVID-19 pandemic and to identify their motives for this season's SIV. Before this influenza season (2020/21), the hospital management offered free SIV to all HCWs and promoted it on the internal network. Read More
