Fine-Needle Portosystemic Pressure Gradient as a Reference for Portal Hypertension in Patients with Intrahepatic Venovenous Shunt: A Prospective Study.

Purpose: To evaluate the consistency and agreement between portal venous pressure measured by fine-needle (F), portal vein catheterization (D), and hepatic vein balloon-occlusion (W) in decompensated cirrhotic patients with intrahepatic venovenous shunts (IHVS).

The F/D/W were assessed for consistency by Pearson coefficient (r), linear regression coefficient (R), and intraclass correlation coefficient (ICC), and for disagreement (error exceeding 20% of D) by Bland-Altman method.

New perspectives on YTHDF2 O-GlcNAc modification in the pathogenesis of intervertebral disc degeneration.

This study investigates the potential molecular mechanisms by which O-GlcNAc modification of YTHDF2 regulates the cell cycle and participates in intervertebral disc degeneration (IDD). We employed transcriptome sequencing to identify genes involved in IDD and utilized bioinformatics analysis to predict key disease-related genes. In vitro mechanistic validation was performed using mouse nucleus pulposus (NP) cells.

Currently, there is a lack of data on patient selection, appropriate medical devices, complication prevention, and TRA adoption.

Hypoxia-activated cascade nanovaccine for synergistic chemoembolization-immune therapy of hepatocellular carcinoma.

In this work, a promising treatment strategy for triggering robust antitumor immune responses in transarterial chemoembolization of hepatocellular carcinoma (HCC) is presented.

Defensive furofuran lignans localized to the oil cells of Neocinnamomum delavayi and their metabolism by a specialist insect.

Neocinnamomum delavayi (Lauraceae) leaves with abundant oil cells are seldom attacked by insects, but their chemical constituent and biological function remain obscure. Three furofuran lignans, including (+)-eudesmin (3), (+)-magnolin (4), and demethoxyaschantin (5), were identified to be the major specialized metabolites in the oil cells of N. delavayi leaves through laser microdissection coupled with NMR analysis.

The influence of shunting left/right portal vein branch on post-TIPS hepatic encephalopathy: a study protocol for multicenter randomized blinded controlled trial.

Introduction: Gastroesophageal varices (GOV) bleeding is a common and serious complication of advanced liver cirrhosis with a median survival of less than 2 years. Multiple guidelines have pointed out that transjugular intrahepatic portosystemic shunt (TIPS) is the rescue treatment of acute variceal hemorrhage (AVB) after failure of standard therapy and an effective second-line treatment for preventing patients with high risks from rebleeding of GOV. The safety and stability of TIPS have been greatly improved due to the improvements of related technologies and the emergence of various novel devices, but the incidence of hepatic encephalopathy (HE) after shunting (10-50%) hindered the widespread use of TIPS.

Three-dimensional-printed MPBI@β-TCP scaffold promotes bone regeneration and impedes osteosarcoma under near-infrared laser irradiation.

Beta-tricalcium phosphate (β-TCP) is considered as one of the most promising biomaterials for bone reconstruction.
