Distinct immune microenvironment of venous tumor thrombus in hepatocellular carcinoma at single-cell resolution.

Background Aims: Portal vein tumor thrombus (PVTT) worsens the prognosis of hepatocellular carcinoma by increasing intrahepatic dissemination and inducing portal vein hypertension. However, the immune characteristics of PVTT remain unclear. Therefore, this study aims to explore the immune microenvironment in PVTT.

Structural insights into the Caprin-2 HR1 domain in canonical Wnt signaling.

The canonical Wnt signaling pathway plays crucial roles in cell fate decisions as well as in pathogenesis of various diseases. Previously, we reported Caprin-2 as a new regulator of canonical Wnt signaling through a mechanism of facilitating LRP5/6 phosphorylation. Here, we resolved the crystal structure of the N-terminal homologous region 1 (HR1) domain of human Caprin-2.

N6-methyladenosine modification of PLOD2 causes spermatocyte damage in rats with varicocele.

Background: In recent years, N6-methyladenosine (mA) methylation modification of mRNA has been studied extensively. It has been reported that mA determines mRNA fate and participates in many cellular functions and reactions, including oxidative stress. The PLOD2 gene encodes a protein that plays a key role in tissue remodeling and fibrotic processes.

Comparison of revascularization with conservative medical treatment in maintenance dialysis patient with coronary artery disease: a systemic review and meta-analysis.

Background: The primary cause of death among maintenance dialysis patients is coronary artery disease (CAD). However, the best treatment plan has not yet been identified.

Methods: The relevant articles were retrieved from various online databases and references from their inception to October 12, 2022.

Bioengineered materials with selective antimicrobial toxicity in biomedicine.

Fungi and bacteria afflict humans with innumerous pathogen-related infections and ailments. Most of the commonly employed microbicidal agents target commensal and pathogenic microorganisms without discrimination. To distinguish and fight the pathogenic species out of the microflora, novel antimicrobials have been developed that selectively target specific bacteria and fungi.

Phosphorylcholine-Primed Dendritic Cells Aggravate the Development of Atherosclerosis in ApoE Mice.

Atherosclerosis is an inflammatory disease involving activation of adaptive and innate immune responses to antigens, including oxidized low-density lipoprotein (oxLDL) and phosphorylcholine (PC). Dendritic cells (DCs), which are antigen-presenting cells that activate T cells, are present in atherosclerotic lesions and are activated in immune organs. However, the mechanism by which PC promotes atherosclerosis is unclear.

[Impact of sperm DNA fragmentation on the outcome of frozen-thawed blastocyst transfer in in vitro fertilization and embryo transfer].

Objective: To study the impact of sperm DNA fragmentation (DF) on the outcome of frozen-thawed blastocyst transfer in in vitro fertilization and embryo transfer (IVF-ET).

Methods: We retrospectively analyzed 308 cases of routine IVF-ET performed at our Center of Reproductive Medicine from January 2016 to January 2018. According to the sperm DNA fragmentation index (DFI), we divided the patients into a normal DFI (DFI ≤ 15%, n = 114), a moderate DFI (15% < DFI ≤ 30%, n = 103), and a high DFI group (DFI > 30 %, n = 91), and compared the development of embryos and clinical outcomes among the three groups.

Down-regulation and Clinical Implication of Galectin-9 Levels in Patients with Acute Coronary Syndrome and Chronic Kidney Disease.

In various autoimmune diseases, Galecin-9 (Gal-9) has been shown to regulate the T-cell balance by decreasing Th1 and Th17, while increasing the number of regulatory T cells (Tregs). However, the role of Gal-9 in the patients with acute coronary syndrome (ACS) and chronic kidney disease (CKD) remains unclear. This study aims to measure the Gal-9 levels in serum and peripheral blood mononuclear cells (PBMCs) in patients with ACS plus CKD and examine their clinical implication.

The Long Noncoding RNA Hotair Regulates Oxidative Stress and Cardiac Myocyte Apoptosis during Ischemia-Reperfusion Injury.

Oxidative stress and subsequent cardiac myocyte apoptosis play central roles in the initiation and progression of myocardial ischemia-reperfusion (I/R) injury. Homeobox transcript antisense intergenic RNA () was previously implicated in various heart diseases, yet its role in myocardial I/R injury has not been clearly demonstrated. Mice with cardiac-restricted knockdown or overexpression of were exposed to I/R surgery.

Plasma oxidized high-density lipoprotein and glycated apolipoprotein A-I concentrations in ST-segment elevation myocardial infarction patients with stress hyperglycaemia or high thrombus burden.

Background: High-density lipoprotein (HDL) particles exert many beneficial actions that may help protect against cardiovascular disease. However, recent work has demonstrated that HDL can be oxidized and glycated under certain circumstances and may become pro-atherogenic. The present study investigated the impact of oxidized high-density lipoprotein (ox-HDL) and glycated apolipoprotein A-I (gly-ApoA-I) in patients presenting with ST-elevation myocardial infarction (STEMI).

Application of vacuum assisted venous drainage in heart surgeries for newborns.

Objective: To explore the role of cardiopulmonary bypass (CPB) with vacuum assisted venous drainage(VAVD)in the management of newborns with congenital heart diseases.

Methods: Total 15 newborns with congenital heart diseases (11 males and 4 females)underwent heart operations. Their age ranged from 2 days to 28 days [mean:(15.

Periodic mesoporous organosilicas with controlled pore symmetries for peptides enrichment.

Periodic mesoporous organosilicas (PMOs) with controlled structures have been synthesized by using cetyltrimethylammonium bromide (CTAB) and sodium perfluorooctanoate (PFONa) as co-templates, 1,2-bis (triethoxysilyl)ethane (BTEE) as an organosilica precursor. By increasing the weight ratio of PFONa/CTAB, a structure transformation from a cubic (Pm-3n) to a two-dimensional hexagonal (p6m) mesostructure and then to multilamellar vesicles can be observed. The cubic and hexagonal samples have similar particle size (200-750 nm), pore size (2.

Overexpression of CXCL16 promotes a vulnerable plaque phenotype in Apolipoprotein E-Knockout Mice.

Background: CXCL16 has been shown to be involved in atherosclerotic lesion development, but its role in preexisting lesions is still unclear. This study aims to assess the effect of CXCL16 on the stability of preexisting lesions.

Methods: We firstly measured plasma CXCL16 level in Apolipoprotein E-Knockout (ApoE KO) mice with either high-cholesterol diet (HCD) or normal diet (ND) by enzyme-linked immunosorbent assay (ELISA).
