Precision DNA methylation typing via hierarchical clustering of Nanopore current signals and attention-based neural network.

Decoding DNA methylation sites through nanopore sequencing has emerged as a cutting-edge technology in the field of DNA methylation research, as it enables direct sequencing of native DNA molecules without the need for prior enzymatic or chemical treatments. During nanopore sequencing, methylation modifications on DNA bases cause changes in electrical current intensity. Therefore, constructing deep neural network models to decode the electrical signals of nanopore sequencing has become a crucial step in methylation site identification.

Advance in glycosyltransferases, the important bioparts for production of diversified ginsenosides.

Ginsenosides are a series of glycosylated triterpenoids predominantly originated from Panax species with multiple pharmacological activities such as anti-aging, mediatory effect on the immune system and the nervous system. During the biosynthesis of ginsenosides, glycosyltransferases play essential roles by transferring various sugar moieties to the sapogenins in contributing to form structure and bioactivity diversified ginsenosides, which makes them important bioparts for synthetic biology-based production of these valuable ginsenosides. In this review, we summarized the functional elucidated glycosyltransferases responsible for ginsenoside biosynthesis, the advance in the protein engineering of UDP-glycosyltransferases (UGTs) and their application with the aim to provide in-depth understanding on ginsenoside-related UGTs for the production of rare ginsenosides applying synthetic biology-based microbial cell factories in the future.

Application of triangular vector to functionally reconstruct the medial collateral ligament with double-bundle allograft technique.

Purpose: The purpose of this study was to present a novel medial collateral ligament (MCL) reconstruction technique and investigate the clinical outcomes of this surgical procedure.

Methods: From July 2006 to June 2009, 56 patients with medial instability of the knee were treated with MCL reconstruction and followed up for 33 months on average. These patients were divided into 2 groups based on whether anterior cruciate ligament (ACL) injury was present: 27 patients had isolated MCL injury, whereas 29 patients had combined MCL-ACL injury.

[Evaluation of surgical outcomes using imaging study for patients with slow transit constipation complicated with outlet obstruction].

Objective: To explore the clinical significance of multiple radiography of the pelvis in the evaluation of surgical outcomes for patients with slow transit constipation complicated with outlet obstruction.

Methods: Patients with slow transit constipation complicated with outlet obstruction were diagnosed by multiple radiography of the pelvis after screening using colon transit study. Surgery was performed according to the cause of the obstruction.
