Enzymes play a vital role in baking, providing significant benefits from dough development to extending shelf life, which enhances product quality and consistency. Acting as biological catalysts, enzymes such as proteases and amylases break down proteins and starches, modifying dough rheology and improving fermentation. Lipases and oxidases further refine dough texture through emulsification and oxidation, while lipases also produce fatty acid derivatives during fermentation, contributing to the flavor and aroma of baked goods.

This study examines the antimicrobial and antibiofilm effectiveness of baicalin and carvacrol against Salmonella enterica ser. Typhimurium on food contact surfaces and chicken meat. The minimum inhibitory concentrations (MIC) for baicalin and carvacrol were found to be 100 μg/mL and 200 μg/mL, respectively, which aligns with findings from previous studies.

In context with growing concerns regarding mechanical damage in nanoelectromechanical systems (NEMS) and energy devices, this study implemented atomistic molecular dynamics simulation to examine the mechanical performance of TiC MXene, a high prospectus material in the field of NEMS and energy technologies. Bond-order Tersoff potential was employed to assess the distinction in the mechanical performance of pristine and vacancy-induced TiC depending on different physiological conditions, including temperature, loading rate, and chirality. A competitive elastic modulus of 130.

Aquaculture is one of the most significant food sources from the prehistoric period. As aquaculture intensifies globally, the prevalence and outbreaks of various pathogenic microorganisms cause fish disease and heavy mortality, leading to a drastic reduction in yield and substantial economic loss. With the modernization of the aquaculture system, a new challenge regarding biofilms or bacterial microenvironments arises worldwide, which facilitates pathogenic microorganisms to survive under unfavorable environmental conditions and withstand various treatments, especially antibiotics and other chemical disinfectants.

The Motile Aeromonas Septicemia (MAS) is an important disease of cultured catfishes ( and ), caused by different species of Aeromonas bacteria which have been documented to be higher death rates (≤70%) in Bangladesh since 2016. Present study was conducted to develop bi-valent vaccine using and , and to validate their efficacy via intra-muscular (IM) and oral-routes of immunization in selected species of fishes. Brood fishes of the three species were immunized with three doses of inactivated vaccine (10 CFU /2.

Cost and safety are critical factors in the oil and gas industry for optimizing wellbore trajectory, which is a constrained and nonlinear optimization problem. In this work, the wellbore trajectory is optimized using the true measured depth, well profile energy, and torque. Numerous metaheuristic algorithms were employed to optimize these objectives by tuning 17 constrained variables, with notable drawbacks including decreased exploitation/exploration capability, local optima trapping, non-uniform distribution of non-dominated solutions, and inability to track isolated minima.

In this study, we determined the effects of dietary chitosan on the growth, biochemical composition, gut microbiota, and hematological and histological parameters of juvenile Barbonymus gonionotus. Three test diets containing three different concentrations (1, 2, and 3 g kg-1 feed) of dietary chitosan were formulated. A basal diet without dietary chitosan was considered a control, and the fish were reared for 60 days.

Article Synopsis
  • * Out of 330 diarrheal samples tested, the overall prevalence of the pathogen was found to be 31.5%, with higher rates in younger age groups, particularly children aged 0-5 years.
  • * A significant portion (27.3% and 31.2%) of the identified pathogens showed multidrug resistance, highlighting the need for effective measures to reduce the incidence and address contributing factors such as hygiene and animal exposure.

Background: The number of tribes present within Bangladesh has been estimated to approximate one hundred and fifty. Information on traditional medicinal practices, particularly of the smaller tribes and their clans is lacking. It was the objective of the study to document the tribal medicinal practices of the Deb barma clan of the Tripura tribe, which clan can be found residing in Dolusora Tripura Palli of Moulvibazar district of Bangladesh.
