Parameters of physical constituents of the agitation process and mass-exchange characteristics of the suggested bioreactor for suspension cultivation of pig splenocytes are determined. The effect of hydrodynamic conditions on viability and interferon-synthesizing activity of cells in production of alpha-interferon of pigs has been studied. The relation existing between interferonogenesis processes proceeding under suspension and under stationary biosynthesis has been analyzed by the pair correlation method.

This study investigates the potential synergistic effects of extracts from (turmeric), (Arabica coffee beans), and (chili peppers) in reducing oxidative stress and inflammation, which are associated with metabolic disorders such as obesity, diabetes, and cardiovascular diseases. Using a systematic design of experiment (DoE) optimization approach, an optimal extract ratio of 1:3:4 (turmeric: coffee: chili) was identified. The efficacy of the extract combination was assessed through various antioxidant assays, inhibition of inflammation-related gene expression, and safety testing via the 3-(4,5-dimethylthazolk-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay.

The corrosion of low-alloy steel in ethanolamine solution, simulating steam generator chemistry, is studied by in situ chronopotentiometry and electrochemical impedance spectroscopy combined with ex situ analysis of the obtained oxide films and model calculations. Hydrodynamic calculations of the proposed setup to study flow-assisted corrosion demonstrate that turbulent conditions are achieved. Quantum chemical calculations indicate the adsorption orientation of ethanolamine on the oxide surface.

Lactoferrin is a highly safe antibacterial protein found in the human body and in foods. Calcium phosphate (CaP) nanoparticles with immobilized lactoferrin could therefore be useful as intraoral disinfectants for the prevention and treatment of dental infections because CaP is a mineral component of human teeth. In this study, we fabricated CaP nanoparticles with co-immobilized lactoferrin and heparin using a simple one-step coprecipitation process.

This study evaluates the performance of continuous flow and drop-based microfluidic devices for the synthesis of silver nanoparticles (AgNPs) under identical hydrodynamic and chemical conditions. Flows at low values of Dean number (De < 1) were investigated, where the contribution of the vortices forming inside the drop to the additional mixing inside the reactor should be most noticeable. In the drop-based microfluidic device, discrete aqueous drops serving as reactors were generated by flow focusing using silicone oil as the continuous phase.

Objective: The triply periodic minimal surface (TPMS) Gyroid porous scaffolds were built with identical porosity while varying pore sizes were used by fluid mechanics finite element analysis (FEA) to simulate the microenvironment. The effects of scaffolds with different pore sizes on cell adhesion, proliferation, and osteogenic differentiation were evaluated through calculating fluid velocity, wall shear stress, and permeability in the scaffolds.
Methods: Three types of gyroid porous scaffolds, with pore sizes of 400, 600 and 800 μm, were established by nTopology software.
