Dipeptidyl peptidase IV inhibitors reduce hepatic fibrosis and lipid accumulation in rat intestinal failure-associated liver disease models.

Purpose: This study aimed to investigate the effectiveness of dipeptidyl peptidase IV inhibitors (DPP4-I) against liver damage, especially fibrosis and lipid accumulation, in a rat intestinal failure-associated liver disease (IFALD) model.

Methods: SD rats were divided into two groups: the Control (n = 7; normal saline + IFALD model) and DPP4-I (n = 7; DPP4-I + IFALD model; short bowel syndrome (SBS) + total parenteral nutrition) groups. All rats were euthanized 21 days postoperatively to obtain tissue samples.

Rapid Glyco-Qualitative Assessment of Recombinant Proteins Using a Fully Automated System.

Protein glycosylation, a critical post-translational modification, influences the stability, efficacy, and immunogenicity of recombinant proteins, including biopharmaceuticals. Glycan structures exhibit significant heterogeneity, varying with production cell types, culture conditions, and purification methods. Consequently, monitoring and evaluating the glycan structures of recombinant proteins is vital, particularly in biopharmaceutical production.

The Clinical Course and Treatment of a Case of Refractory Systemic Juvenile Myasthenia Gravis Successfully Treated with Thymectomy.

Juvenile myasthenia gravis (JMG) exhibits a more favorable response to glucocorticoids and has a better prognosis than adult myasthenia gravis. However, no established treatment exists for refractory JMG. Although thymectomy has been performed in several patients with refractory systemic JMG, there are few detailed clinical descriptions of patients who underwent thymectomy.

Auto-Lectin Dotcoding by Two Octopuses: Rapid Analysis of Fluorescence-Labeled Glycoproteins by an 8-channel Fully-Automatic Bead Array Scanner with a Rolling-Circle Detector.

Protein glycosylation is a crucial factor that must be evaluated in biological pharmaceuticals. The glycoform profile of a protein can vary depending on the conditions of the cultivation, purification process, and the selection of a host cell. Lectin microarrays are reliable bioanalytical methods used in the early phases of bioprocesses for the detection of glycosylation.
