Frailty and fractures are closely associated with adverse clinical outcomes. This retrospective study investigated the prognostic impact of frailty, prevalent fractures, and the coexistence of both in patients with cirrhosis. Frailty was defined according to the Fried frailty phenotype criteria: weight loss, weakness, exhaustion, slowness, and low physical activity.

However, it is still difficult to make spinal osteotomy less invasive, and the high complication rate is an issue.
Observations: The authors present the surgical techniques of a two-stage Schwab grade 4 spinal osteotomy using LLIF, which could reduce surgical invasiveness and enable good correction and anterior spinal column reconstruction for lumbar kyphosis, and also report a case treated with this procedure.
Lipolysis-stimulated lipoprotein receptor (LSR), a lipid metabolism-related factor localized in tricellular tight junctions (tTJs), plays an important role in maintaining the epithelial homeostasis. LSR is highly expressed in well-differentiated cancers, and its expression decreases during malignancy. The LSR antibody inhibits cell growth and promotes apoptosis in some cancers.

These enzymes uniquely have a non-catalytic lectin domain, which selectively recognizes the GnT-IV product -glycan branch, but the role of this lectin domain has remained unclear. Here, using UDP-Glo enzyme assays, we discovered that this domain is required for activity toward glycoprotein substrates but not toward free glycans.

Background: N-Glycan branching modulates the diversity of protein functions. β1,4-N-acetylglucosaminyltransferase III (GnT-III or MGAT3) produces a unique GlcNAc branch, "bisecting GlcNAc", in N-glycans, and is involved in Alzheimer's disease and cancer. However, the 3D structure and catalytic mechanism of GnT-III are unclear.
