Impact of thrombocytopenia on failure of endoscopic variceal treatment in cirrhotic patients with acute variceal bleeding.

Background: Acute variceal bleeding (AVB), a life-threatening complication of liver cirrhosis, can be effectively treated by endoscopy, but there is a risk of early rebleeding after endoscopic variceal treatment (EVT). Thrombocytopenia is the most common hemostatic abnormality in liver cirrhosis. However, it is still unclear about whether thrombocytopenia increases the failure of EVT in cirrhotic patients with AVB.

The relationship between problematic internet use and psychological distress in older Chinese teachers (40+) during different stages of the COVID-19 pandemic: three cross-sectional studies.

Fine-Tuning Intra/Inter-Molecular Interaction via Ternary Copolymerization Strategy to Obtain Efficient Polymer Donors.

Incorporating a third component through ternary copolymerization strategy has proven to be a promising and effective approach for further improving the device performance of polymer donors. However, terpolymer donors typically exhibit negative effects on molecular stacking and weaken charge transport due to the irregular distribution of the polymer skeleton. Herein, two terpolymers PBBQ-5 (5% ff-Qx) and PBBQ-10 (10% ff-Qx) are developed by introducing the difluoro-2-(3-hexyldecyloxy) quinoxaline (ff-Qx) to the main chain of PM6.

In situ Polymerized Solid-State Electrolyte Enabling Inorganic-Organic Dual-Layered SEI Film for Stable Lithium Metal Batteries.

In situ polymerization of cyclic ethers is a promising strategy to construct solid-state lithium (Li) metal batteries with high energy density and safety. However, their practical applications are plagued by the unsatisfactory electrochemical properties of polymer electrolytes and the unstable solid electrolyte interphase (SEI). Herein, organic perfluorodecanoic acid (PFDA) is proposed as a new initiator to polymerize 1,3-dioxolane electrolyte (PDOL), which enables the as-obtained PDOL electrolyte to deliver greatly enhanced ionic conductivity and broadened electrochemical window.

Five racemic phthalides from the aerial parts of Lycopodiastrum casuarinoides and their neuroprotective activities.

Five racemic phthalides (1-5), including four undescribed phthalides monomers [(+)-1, (+)-2, (-)-2 and (-)-3], four undescribed phthalide dimers [(+)-4, (-)-4, (+)-5 and (-)-5], together with two known compounds [(-)-1 and (+)-3], were isolated from the aerial parts of Lycopodistrum casuarinoides. Their chemical structures were delineated by extensive spectroscopic data (UV, 1D/2D NMR, HRESIMS), in combination with the comparison of the experimental and calculated electronic circular dichroism spectra, calculated spin-spin coupling constants, and calculated NMR. All compounds were reported from Lycopodiaceae family for the first time.

Sirt6, Deubiquitinated and Stabilised by USP9X, Takes Essential Actions on the Pathogenesis of Experimental Autoimmune Myasthenia Gravis by Regulating CD4 T Cells.

Myasthenia gravis (MG) presents with symptoms that significantly affect patients' daily lives. Long-term MG therapies may lead to substantial side effects, predominantly due to prolonged immune suppression. Sirt6, which plays a vital role in maintaining cellular homeostasis and is recognised for its involvement in cytokine production in immune cells, has not yet been explored in relation to MG.

Selenium yeast alleviates diquat-induced oxidative stress and testicular damage in roosters.

Diquat (DQ) is a pro-oxidant that generates free radicals in cells through redox reactions, leading to the induction of oxidative stress. During the processes of growth and reproduction, poultry are particularly vulnerable to oxidative stress. Selenium yeast (SeY) serves as an organic selenium source characterized by high activity and low toxicity, imparting antioxidant effects.

Enhanced removal of sulfonamide antibiotics in water using high-performance S-nZVI/BC derived from rice straw.

Influence of coal gangue-aeolian sand aggregate gradation on rheological properties and pipeline transportation characteristics of filling slurry.

Uneven of filling aggregate gradation may cause transportation problems such as pipe blockage due to segregation and stratification of filling slurry. To study the influence of aggregate gradation on the conveying performance of filler slurry, aggregate gradation experiments were carried out, rheological tests on slurries with coal gangue/aeolian sand ratios (6:4, 5:5 and 4:6) showed that appropriately increasing the proportion of aeolian sand can improve particle gradation. Computational fluid dynamics (CFD) scheme was used to simulate the pipeline transportation characteristics of the slurry under the conditions of three sets each of coal gangue/aeolian sand ratios, slurry concentrations (72%,74% and 76%), and inlet velocities (1.
