Prenatal Exposure to LPS Alters The Intrarenal RAS in Offspring, Which Is Ameliorated by Adipose Tissue-Derived Mesenchymal Stem Cells.

Background: Prenatal lipopolysaccharide (LPS) exposure causes hypertension in rat offspring through an unknown mechanism. Here, we investigated the role of the intrarenal renin-angiotensin system (RAS) in hypertension induced by prenatal LPS exposure and also explored whether adipose tissue-derived mesenchymal stem cells (ADSCs) can ameliorate the effects of prenatal LPS exposure in rat offspring.

Methods: Sixty-four pregnant rats were randomly divided into 4 groups (n = 16 in each), namely, a control group and an LPS group, which were intraperitoneally injected with vehicle and 0.

Pharmacological activation of the Nrf2 pathway by 3H-1, 2-dithiole-3-thione is neuroprotective in a mouse model of Alzheimer disease.

Accumulating evidence suggests that oxidative stress induced by beta-amyloid (Aβ) is implicated in the pathlogical progression of Alzheimer's disease (AD). 3H-1,2-dithiole-3-thione (D3T), the simplest compound of the sulfur-containing dithiolethiones, has been proved to be a strongly active antioxidant factor by regulation of the nuclear factor E2-related factor 2 (Nrf2). Previous study reported that D3T confers protection to AD cell model in vitro, however, the neuroprotective effect of D3T in the AD mammalian model is unknown.

Human umbilical cord mesenchymal stem cells transplantation improves cognitive function in Alzheimer's disease mice by decreasing oxidative stress and promoting hippocampal neurogenesis.

Stem cell transplantation represents a promising therapy for central nervous system injuries, but its application to Alzheimer's disease (AD) is still limited and the potential mechanism for cognition improvement remains to be elucidated. In the present study, we used Tg2576 mice which express AD-like pathological forms of amyloid precursor protein (APP) to investigate the effects of human umbilical cord mesenchymal stem cells (hUC-MSCs) intravenous transplantation on AD mice. Interestingly, hUC-MSCs transplantation significantly ameliorated cognitive function of AD mice without altering Aβ levels in hippocampus.

Constructing bio-layer of heparin and type IV collagen on titanium surface for improving its endothelialization and blood compatibility.

The modification of cardiovascular stent surface for a better micro-environment has gradually changed to multi-molecule, multi-functional designation. In this study, heparin (Hep) and type IV collagen (IVCol) were used as the functional molecule to construct a bifunctional micro-environment of anticoagulation and promoting endothelialization on titanium (Ti). The surface characterization results (AFM, Alcian Blue 8GX Staining and fluorescence staining of IVCol) indicated that the bio-layer of Hep and IVCol were successfully fabricated on the Ti surface through electrostatic self-assembly.

The Effects of Intra-Aortic Balloon Pumps on Mortality in Patients Undergoing High-Risk Coronary Revascularization: A Meta-Analysis of Randomized Controlled Trials of Coronary Artery Bypass Grafting and Stenting Era.

Background: Intra-aortic balloon pumps (IABP) have generally been used for patients undergoing high-risk mechanical coronary revascularization. However, there is still insufficient evidence to determine whether they can improve outcomes in reperfusion therapy patients, mainly by percutaneous coronary intervention (PCI) with stenting or coronary artery bypass graft (CABG). This study was designed to determine the difference between high-risk mechanical coronary revascularization with and without IABPs on mortality, by performing a meta-analysis on randomized controlled trials of the current era.

Serum total bilirubin and long-term outcome in patients undergoing percutaneous coronary intervention.

Purpose: The purpose of this study was to investigate the associated between serum total bilirubin (STB) levels and long-term outcomes in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI).

Methods: A total of 1,273 consecutive patients were enrolled. Patients were grouped according to their baseline STB levels: Group 1 (STB < 3.

Effect of statin therapy on mortality from infection and sepsis: a meta-analysis of randomized and observational studies.

Introduction: Observational data have suggested that statin therapy may reduce mortality in patients with infection and sepsis; however, results from randomized studies are contradictory and do not support the use of statins in this context. Here, we performed a meta-analysis to investigate the effects of statin therapy on mortality from infection and sepsis.

Methods: We searched electronic databases (PubMed and Embase) for articles published before November 2013.

Biocompatibility of nano-hydroxyapatite/Mg-Zn-Ca alloy composite scaffolds to human umbilical cord mesenchymal stem cells from Wharton's jelly in vitro.

Seeding cells and scaffolds play pivotal roles in bone tissue engineering and regenerative medicine. Wharton's jelly-derived mesenchymal stem cells (WJCs) from human umbilical cord represent attractive and promising seeding cells in tissue regeneration and engineering for treatment applications. This study was carried out to explore the biocompatibility of scaffolds to seeding cells in vitro.

[The protective effects of SB203580 against mortality and radiation induced intestinal injury of mice].

This study is to investigate the protective effects of the SB203580 against radiation induced mortality and intestinal injury of mice. A total of 67 male C57BL/6 mice (20.0-22.

[Treatment of brain injured rats through transplanting amniotic-derived mesenchymal stem cells in different ways].

Objective: To compare the behavioral improvement to find the best transplantation approach for treating brain injury through transplanting amniotic-derived mesenchymal stem cells into brain injured rats in different ways.

Methods: Eighty brain injured Wista rats were randomly divided into a control group with brain injury alone (n=20) and a treatment group(n=60) which were further evenly divided into Group A (transplanted through the vena caudalis), Group B (transplanted through the ventriculus cerebri lateralis), and Group C (transplanted through the injured brain area). Each group was transplanted with amniotic-derived esenchymal stem cells, and their therapeutic efficacy would be evaluated through the neurological severity score (NSS).
