The timing of surgical interventions following the implantation of coronary drug-eluting stents in patients undergoing gastrointestinal cancer surgery: a multicenter retrospective cohort study.

Abstract: We aim to investigate the optimal timing for surgical interventions to maximize patient benefit.

Background: The guidelines recommending a minimum deferral of six months for non-cardiac surgeries following drug-eluting stent percutaneous coronary intervention (DES-PCI) do not adequately address the requirements for individuals undergoing gastrointestinal cancer surgery (GCS).

Methods: The study encompassed 2,501 patients treated from January 2017 to December 2021, all of whom underwent GCS within one year after DES-PCI.

Genome-wide association study of high-altitude pulmonary edema in a Han Chinese population.

A two-stage genome-wide association study (GWAS) was performed to identify and analyze genes and single nucleotide polymorphisms (SNPs) associated with high-altitude pulmonary edema (HAPE) in a Han Chinese patient population. In the first stage, DNA samples from 68 patients with recurrent HAPE were scanned using Affymetrix SNP Array 6.0 Chips, and allele frequencies were compared to those of 84 HapMap CHB samples to identify candidate SNPs.

Nitric Oxide Regulates The Lymphatic Reactivity Following Hemorrhagic Shock Through Atp-Sensitive Potassium Channel.

Lymphatic reactivity has been shown to exhibit a biphasic change following hemorrhagic shock, and nitric oxide (NO) is involved in this process. However, the precise mechanism responsible for NO regulation of the lymphatic reactivity along with the progression of hemorrhagic shock is unclear. Therefore, the present study was to investigate how NO participates in regulating the shock-induced biphasic changes in lymphatic reactivity and its underlying mechanisms.

TOPK is highly expressed in circulating tumor cells, enabling metastasis of prostate cancer.

Circulating tumor cells (CTCs) are important for metastasis in prostate cancer. T-LAK cell-originated protein kinase (TOPK) is highly expressed in cancer cells. Herein, we established a xenograft animal model, isolated and cultured the CTCs, and found CTCs have significantly greater migratory capacity than parental cells.

[Reactivity to substance P of isolated lymphatics in hemorrhagic shock rat].

Objective: To observe the change of lymphatic reactivity to substance P (SP) during the process of hemorrhagic shock (HS) with a technique of lymphatic perfusion in vitro in this study.

Methods: Male Wistar rats were randomly divided into control group (surgical procedure only) and HS group (the rats in this group were further divided into five subgroups: shock 0 h, 0.5 h, 1 h, 2 h and 3 h groups after duplicating the HS model with method of bloodletting to mean arterial blood pressure was 40 mmHg through the femoral venous).

[Nitric oxide modulates biphasic changes of isolated lymphatic contraction in hemorrhagic shock rats].

The aim of the present study was to investigate the changes of lymphatic contraction after hemorrhagic shock in vitro and the underlying role of nitric oxide (NO). Rat thoracic duct segments were isolated at 0, 0.5, 1, 2 and 3 h after hemorrhagic shock.

Epimorphin regulates bile duct formation via effects on mitosis orientation in rat liver epithelial stem-like cells.

Understanding how hepatic precursor cells can generate differentiated bile ducts is crucial for studies on epithelial morphogenesis and for development of cell therapies for hepatobiliary diseases. Epimorphin (EPM) is a key morphogen for duct morphogenesis in various epithelial organs. The role of EPM in bile duct formation (DF) from hepatic precursor cells, however, is not known.

The template-free synthesis of square-shaped SnO(2) nanowires: the temperature effect and acetone gas sensors.

Square-shaped single-crystalline SnO(2) nanowires and their sphere-like hierarchical structures were synthesized successfully with a template-free hydrothermal approach. It was found that an intermediate phase-Na(2)Sn(OH)(6)-is first produced because it is slow to dissolve in ethanol/water media. The intermediate phase gradually decomposes and converts into SnO(2) at temperatures higher than 200 °C.

Overexpression of SPINDLIN1 induces cellular senescence, multinucleation and apoptosis.

Human or mouse Spindlin1 is expressed in various tissues and cells, but its biological functions are poorly understood. In this study, we show that human SPINDLIN1 is localized to interphase nucleus and mitotic chromosomes, and its expression in HeLa cells is not regulated in a cell cycle-dependent manner. When SPINDLIN1 is stably overexpressed in HeLa cells, it results in multinucleation of cells, and these multinucleated cells exhibits characteristic features of senescence and apoptosis shown by growth and morphological alterations, beta-galactosidase activity, and Annexin V/7-Aminoactinomycin D staining.

Structure of human spindlin1. Tandem tudor-like domains for cell cycle regulation.

Spindlin1, a meiotic spindle-binding protein that is highly expressed in ovarian cancer cells, was first identified as a gene involved in gametogenesis. It appeared to be a target for cell cycle-dependent phosphorylation and was demonstrated to disturb the cell cycle. Here we report the crystal structure of human spindlin1 to 2.

Detection of H. pylori antibody profile in serum by protein array.

Aim: To detect multiple H. pylori antibodies in serum samples of individuals who carry H. pylori by protein array.

Expression, purification, crystallization and preliminary X-ray analysis of human spindlin1, an ovarian cancer-related protein.

Human spindlin1 is a newly screened and identified gene product related to ovarian carcinomas and is highly homologous to mouse spindlin. It is an abundant maternal transcript expressed in the mouse during the transition from oocyte to embryo. Here, the recombinant human spindlin1 has been overexpressed in Escherichia coli BL21, purified and crystallized using the hanging-drop vapour-diffusion method.
