Optimization of Culture Medium for Lactobacillus bulgaricus using Box-Behnken Design

open access: yesActa Universitatis Cibiniensis. Series E: Food Technology, 2017
Lactobacillus bulgaricus is a common yogurt starter in dairy production. But the viable counts of the bacteria in the productions are relatively low during free-drying and storage which is not good for its commercial production.

Development of a Predictive Flow Through Cell Dissolution Method for Carbamazepine Modified‐Release Tablets

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 5, May 2026.
ABSTRACT Predictive in vitro dissolution methods are crucial for anticipating in vivo drug performance, particularly for poorly soluble drugs like carbamazepine. In vitro‐in vivo correlations (IVIVC) link dissolution characteristics to pharmacokinetics, facilitating bioequivalence studies and reducing reliance on clinical trials.

Concurrent Oxidative and Reductive Protometabolic Reactions Driven by Electrochemistry

open access: yesChemSystemsChem, Volume 8, Issue 3, May 2026.
Electrochemistry offers a possible solution to a key question in prebiotic chemistry: how oxidative and reductive reactions could occur simultaneously as they do in modern biochemistry. This study shows that essential redox reactions from the reverse tricarboxylic acid (rTCA) cycle and nucleotide synthesis can be driven concurrently by electrochemistry,
