The influence of UHMWPE with varying morphologies on the non-isothermal crystallization kinetics of HDPE.

The current study aims to examine how the morphology of ultra-high molecular weight polyethylene (UHMWPE) particles impacts the kinetics of non-isothermal crystallization in high-density polyethylene (HDPE). To prepare blends of HDPE and UHMWPE, melt blending is utilized. High-temperature melting and subsequent shearing are used to cause the morphological changes in UHMWPE particles.

Smoking, alcohol consumption and risk of Dupuytren's disease: a Mendelian randomization study.

Background: The correlation between smoking and alcohol consumption and the development of Dupuytren's disease (DD) has been acknowledged. However, the definitive causal relationship between these two factors and DD remains elusive. In order to establish a causal connection, we employed the two-sample Mendelian randomization method to evaluate the relationship between smoking and alcohol consumption and DD.

Comparison of Interlaminar and Transforaminal Approaches for Treatment of L /S Disc Herniation by Percutaneous Endoscopic Discectomy.

Objective: The aim of this study was to compare the clinical efficacy of percutaneous endoscopic interlaminar discectomy (PEID) and percutaneous endoscopic transforaminal discectomy (PETD) in treating L /S disc herniation.

Methods: A retrospective analysis of 76 patients with L /S intervertebral disc herniation was performed. There were two surgical treatment groups: one with patients receiving PEID and the other with patients receiving PETD.

The role and clinical significance of long noncoding RNA zinc finger E-box-binding homeobox two antisense RNA 1 in promoting osteosarcoma cancer cell proliferation, inhibiting apoptosis and increasing migration by regulating miR-145.

We aimed to investigate the expression level of long noncoding RNA (lncRNA) zinc finger E-box-binding homeobox two antisense RNA 1 (ZEB2-AS1) in osteosarcoma and explore its possible regulatory mechanisms. Expression of lncRNA ZEB2-AS1 was detected by quantitative real-time PCR in 63 cancerous tissues and 25 adjacent normal mucosal tissues from patients with osteosarcoma. The correlation between the lncRNA ZEB2-AS1 level and clinicopathological characteristics of the osteosarcoma patients were evaluated, and 5-year overall survival (5OS) was also analyzed according to lncRNA ZEB2-AS1 expression.

Cyclical patterns and (im)mobilization mechanisms of phosphorus in sediments from a small creek estuary: Evidence from in situ monthly sampling and indoor experiments.

Internal phosphorus (P) mobility is crucially important to overlying water ecosystems, while its spatiotemporal variations and mechanisms remain to be studied, especially in dynamic estuarine sediments. In this study, in situ monthly field sampling and indoor experiments were combined to measure the soluble reactive P (SRP), soluble Fe and diffusive gradients in thin films (DGT)-labile P/S in the overlying water, sediment and porewater in the Jiuxi River Estuary by employing high-resolution dialysis (HR-Peeper), the DGT technique and a MicroRhizon sampler. The consistent tendency between DGT-labile S and P in most seasons indicates that P mobilization was dominated by intense dissimilatory sulfate reduction (DSR), causing high SRP concentrations and active exchange with the overlying water.

Corrosion behavior and mechanism of carbon steel influenced by interior deposit microflora of an in-service pipeline.

Investigation of carbon steel corrosion influenced by in-situ microbial communities can provide reliable information about microbiologically influenced corrosion (MIC) in the oil and gas field. Here, we investigated the 90-day corrosion behavior of Q235 carbon steel influenced by interior deposit microflora of an in-service pipeline using open circuit potential (OCP) and electrochemical impedance spectroscopy (EIS). Linear sweep voltammetry (LSV), 16S rRNA gene sequencing, and surface analysis were used to comprehensively analyze the corrosion mechanisms.

Metal/metalloid and phosphorus characteristics in porewater associated with manganese geochemistry: A case study in the Jiulong River Estuary, China.

Sediment porewater can be an important source of contaminants in the overlying water, but the mechanisms of metal(loid) and phosphorus (P) remobilization remain to be investigated. In this study, high-resolution dialysis (HR-Peeper) and diffusive gradients in thin films (DGT) samplers were used to determine the porewater dissolved iron (Fe), manganese (Mn), cobalt (Co), chromium (Cr), vanadium (V), selenium (Se), arsenic (As), P and DGT-Labile S in coastal sediments in the Jiulong River Estuary (JRE), China. The results showed that high concentrations of dissolved Mn, Se and P were present in the overlying water, indicating potential water pollution with excessive amounts of Mn, Se and P.

Laboratory and field evaluations of transgenic soybean exhibiting high-dose expression of a synthetic Bacillus thuringiensis cry1A gene for control of Lepidoptera.

Transgenic lines of soybean, Glycine max (L.) Merrill, expressing a synthetic cry1A gene (tic107) from Bacillus thuringiensis (Bt), were evaluated in screenhouse and conventional field trials for efficacy against lepidopteran pests. In screenhouse trials, Bt soybean and negative checks (isogenic segregants and parental lines) were evaluated against Anticarsia gemmatalis Hübner and Pseudoplusia includens (Walker) in the United States and against A.

Changes of Myocardial Muscarinic Receptor during Septic Shock of the Rat.

The present study reports the structural and functional changes of myocardial muscarinic receptor during early and late septic shock, Septic shock was induced by caecum ligation and puncture (CLP). The results showed that the number of M receptor on sarcolemma (SL) increased and that on the light vesicle (LV) decreased during early septic shock. The (3)H-QNB binding of M receptor on SL increased by 33.
