Screening of high glucose tolerant Escherichia coli for L-valine fermentation by autonomous evolutionary mutation.

L-valine holds wide-ranging applications in medicine, food, feed, and various industrial sectors. Escherichia coli, a pivotal strain in industrial L-valine production, features a concise fermentation period and a well-defined genetic background. This study focuses on mismatch repair genes (mutH, mutL, mutS, and recG) and genes associated with mutagenesis (dinB, rpoS, rpoD, and recA), employing a high-glucose adaptive culture in conjunction with metabolic modifications to systematically screen for superior phenotypes.

A life course approach to examine cumulative impacts of parental migration on children's psychological well-being and education in Southeast Asia.

Researchers have raised concerns about parental migration's effects on various aspects of the left-behind children's development. However, there is limited understanding of how parental migration influences children over the life course. This study aimed to fill this gap by investigating how exposure to parental migration during childhood shapes later development in Indonesia and the Philippines, two major labor-sending countries in Southeast Asia.

KRT9 is required for GBP5 suppression of human respiratory syncytial virus.

Unlabelled: Respiratory syncytial virus (RSV) infections continue to plague infants, young children, and older individuals worldwide. Since there is no specific treatment for RSV, characterizing the interactions between RSV and host factors remains crucial for the eventual development of robust therapeutic interventions. In our previous study, guanylate binding protein 5 (GBP5) was shown to promote excessive RSV-small hydrophobic (RSV-SH) protein secretion by microvesicles and inhibited viral replication.

Unilateral Lumbo-Pelvic Fixation for Denis Type I Unilateral Sacral Fracture: A Finite Element Analysis.

Background: Unilateral sacral fractures with posterior ring instability represent a prevalent type of posterior pelvic ring fracture. While lumbo-pelvic fixation is recognized as a highly stable method, the sufficiency of unilateral lumbo-pelvic fixation (ULF) for such fractures remains under debate.

Purpose: This study aims to assess the biomechanical stability of ULF compared to traditional bilateral lumbo-pelvic fixation (BLF) and triangular osteosynthesis (TO), incorporating clinical observations, and previous biomechanical data.

An updated review on abnormal epigenetic modifications in the pathogenesis of systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease. The inconsistent prevalence of SLE between monozygotic twins suggests that environmental factors affect the occurrence of this disease. Abnormal epigenetic regulation is strongly associated with the pathogenesis of SLE.
