Azolation of Benzylic C-H Bonds via Photoredox-Catalyzed Carbocation Generation.

A visible-light photoredox-catalyzed method is reported that enables the coupling between benzylic C-H substrates and N-H azoles. Classically, medicinally relevant -benzyl azoles are produced via harsh substitution conditions between the azole and a benzyl electrophile in the presence of strong bases at high temperatures. Use of C-H bonds as the alkylating partner streamlines the preparation of these important motifs.

Evaluation of Simulated Shelf-Life Conditions for Food Service Applications on Chicken Tenderloins.

The objective of this study was to validate the shelf-life of marinated and frozen chicken tenderloins. Treatments were randomly assigned to the age of the tenderloins post-harvest, days aged (DA): DA4, DA5, DA6, DA7, and DA8. Microbial analyses were used to analyze the growth of aerobic, psychotropic, and lactobacilli bacteria to assess the shelf-life of bulk-packaged chicken tenderloins.

Translocation of Orally Inoculated Following Mild Immunosuppression in Holstein Calves and the Presence of the in Ground Beef Samples.

The objective of this study was to determine if immunosuppression through daily dexamethasone (DEX) infusion altered translocation from the gastrointestinal tract. Weaned Holstein steers ( = 20; body weight [BW] = 102 ± 2.7 kg) received DEX ( = 10; 0.

Formation of Sublethally Injured Yersinia enterocolitica, Escherichia coli O157:H7, and Salmonella enterica Serovar Enteritidis Cells after Neutral Electrolyzed Oxidizing Water Treatments.

The impact of neutral electrolyzed oxidizing (NEO) water treatments on the formation of sublethally injured , O157:H7, and serovar Enteritidis cells was evaluated. When pathogens were treated with 6% NEO water, approximately 38% of the treated population and 25% of the treated population became sublethally injured. The highest sublethally injured population was found when cultures were treated with 3% NEO water.

Differentiation of commercial ground beef products and correlation between metabolites and sensory attributes: A metabolomic approach.

Three traditional grinds (commodity products) and 7 non-traditional grinds (branded products) were obtained to investigate the metabolites in ground beef associated with beef flavor or off-flavor. Three packaging methods were used: traditional overwrap, modified atmosphere package, and clear plastic retail chub. Samples were collected for sensory evaluation and metabolic profiling utilizing LC/MS.
