Inactivation of Salmonella Enteritidis on Hatchery and Table Eggs Using a Gas-phase Hydroxyl-Radical Process.

Eggs represent a significant vehicle for Salmonella Enteritidis with the pathogen being transferred to chicks in the hatchery, or to consumers via table eggs. In the following, the efficacy of a gas-phase hydroxyl-radical process for decontaminating hatchery and table eggs was evaluated. Recovery of Salmonella was maximized through holding eggs in tryptic soy broth containing 20% w/v glycerol for 1 h prior to plating.

Sexual dimorphism modulates metabolic and cognitive alterations under HFD nutrition and chronic stress exposure in mice. Correlation between spatial memory impairment and BDNF mRNA expression in hippocampus and spleen.

Aims: The accumulated evidence suggests that lifestyle - specifically dietary habits and stress exposure - plays a detrimental role in health. The purpose of the present study was to analyze the interplay of stress, diet, and sex in metabolic and cognitive alterations.

Main Methods: For this purpose, one-month-old C57Bl/6J mice were fed with a standard diet or high-fat diet (HFD).

Investigation of the Azorean Processing Conditions to Maximize the Theaflavin 3,3'-di--Gallate Content as a Potential Antiviral Compound.

The molecular constituents of , in particular epigallocatechin-3--gallate (EGCG) and, more remarkably, the galloylated theaflavins, mainly theaflavin-3,3'-di--gallate (TF-3,3'-DG), have been reported to inhibit SARS-CoV-2 3-chymotrypsin-like protease (3CL), an enzyme required for the cleavage of its polyproteins, to produce vital individual functional proteins for viral cell replication. Our results for total catechin content revealed the values of 174.72, 200.

Bromelain, a Group of Pineapple Proteolytic Complex Enzymes () and Their Possible Therapeutic and Clinical Effects. A Summary.

Bromelain is a complex combination of multiple endopeptidases of thiol and other compounds derived from the pineapple fruit, stem and/or root. Fruit bromelain and stem bromelain are produced completely distinctly and comprise unique compounds of enzymes, and the descriptor "Bromelain" originally referred in actuality to stem bromelain. Due to the efficacy of oral administration in the body, as a safe phytotherapeutic medication, bromelain was commonly suited for patients due to lack of compromise in its peptidase efficacy and the absence of undesired side effects.

Prenatal stress promotes insulin resistance without inflammation or obesity in C57BL/6J male mice.

During gestation, stress exposure increases the risk of developing cognitive and physiological alterations in either the long or short term. Among them, metabolic alterations have been described. Adipose tissue is responsible for the secretion of several factors involved in controlling body weight and energy expenditure, the regulation of insulin sensitivity, and the development of inflammation, among others.
