CFD-Based Determination of Optimal Design and Operating Conditions of a Fermentation Reactor Using Bayesian Optimization.

The efficiency of fermentation reactors is significantly impacted by gas dispersion and concentration distribution, which are influenced by the reactor's design and operating conditions. As the process scales up, optimizing these parameters becomes crucial due to the pronounced concentration gradients that can arise. This study integrates the kinetics of the fermentation process with hydrodynamic analysis using Bayesian optimization to efficiently determine the optimal reactor design and operating conditions.

Therapeutic effect of novel drug candidate, PRG-N-01, on NF2 syndrome-related tumor.

Background: NF2-related schwannomatosis (NF2-SWN) is associated with multiple benign tumors in the nervous system. NF2-SWN, caused by mutations in the NF2 gene, has developed into intracranial and spinal schwannomas. Because of the high surgical risk and frequent recurrence of multiple tumors, targeted therapy is necessary.

Investigating the influence of working status changes on physical activity and non-communicable diseases in Korean middle-aged and older adults: insights from a longitudinal panel study.

Background: Non-communicable diseases (NCDs) are a major global health challenge and occupational status is a critical determinant influencing NCD development, yet many cross-sectional studies have only linked current occupational status with specific diseases, overlooking broader temporal factors. The primary aim of the present study was to comprehensively elucidate the intricate interplay between alterations in working status, NCDs, and physical activity (PA) among Korean middle-aged and older adults, employing a longitudinal panel study design.

Methods: This study utilized longitudinal data from the Korean Longitudinal Study of Aging, covering the period from 2006 to 2020, with a median follow-up duration of 10 years.

Therapeutic role of aripiprazole in cartilage defects explored through a drug repurposing approach.

Articular cartilage has a limited regenerative capacity, resulting in poor spontaneous healing of damaged tissue. Despite various scientific efforts to enhance cartilage repair, no single method has yielded satisfactory results. With rising drug development costs, drug repositioning has emerged as a viable alternative.

Differential Regulatory Effects of Probiotics on Bone Metabolism by the Status of Bone Health and Delivery Route.

Probiotics are known to have favorable effects on human health. Nevertheless, probiotics are not always beneficial and can cause unintended adverse effects such as bacteremia and/or inflammation in immunocompromised patients. In the present study, we investigated the effects of probiotics on the regulation of bone metabolism under different health conditions and delivery routes.
