Experimental Research on Distribution Characteristics of NO Conversion Efficiency of a Diesel Engine SCR Catalyst.

An experimental investigation of the distribution characteristics of NO conversion efficiency inside a selective catalytic reduction system is presented in this paper. Wash-coated and extruded vanadium-based selective catalytic reduction catalysts were investigated under an ANR (ammonia nitrogen ratio) of 1.0 and various exhaust gas temperature and flow rate conditions.

The dominant models of KCNJ11 E23K and KCNMB1 E65K are associated with essential hypertension (EH) in Asian: Evidence from a meta-analysis.

Background: The K channel, subfamily J, member-11 (KCNJ11) E23K and β1 subunit of large-conductance Ca-activated K channel (KCNMB1) E65K polymorphisms were shown to be associated with the risk of essential hypertension (EH). However, the results were inconclusive with relatively small sample size. Thus, we carried out a meta-analysis to investigate the genetic association between KCNJ11 E23K and KCNMB1 E65K polymorphisms and essential hypertension risk.

ADAR1 silencing-induced HUVEC apoptosis is mediated by FGFR2 under hypoxia stress.

Background: The adenosine deaminase acting on RNA 1 (ADAR1) specifically deaminates adenosine to inosine in double-stranded RNA (dsRNA). Emerging evidence indicated that under hypoxia condition, such as tumor microenvironment, ADAR1 level was increased. Interestingly, we found FGFR2 was also increased under hypoxia stress.

Spousal concordance for hypertension: A meta-analysis of observational studies.

The authors performed a meta-analysis of observational studies to estimate the magnitude of spousal concordance for hypertension and to examine whether the concordance varied by important study methodological aspects. PubMed and Embase were searched up to June 2017 for cross-sectional, case-control, and cohort studies that investigated the concordance/association of hypertension between spouse pairs. A meta-analysis with random-effects models was performed by pooling adjusted odds ratios.

Prevalence and Spectrum of TBX5 Mutation in Patients with Lone Atrial Fibrillation.

Atrial fibrillation (AF), the most common type of cardiac rhythm disturbance encountered in clinical practice, is associated with substantially increased morbidity and mortality. Aggregating evidence demonstrates that abnormal cardiovascular development is involved in the pathogenesis of AF. A recent study has revealed that the TBX5 gene, which encodes a T-box transcription factor key to cardiovascular development, was associated with AF and atypical Holt-Oram syndrome.

Endothelial progenitor cells and atherosclerosis.

Atherosclerosis is due to inflammation and endothelial dysfunction and damage caused by a variety of factors. Dysfunction of endothelial progenitor cells (EPCs) that differentiate into mature endothelial cell contributes to the development of atherosclerosis. Both the number and functionality of EPCs are regulated, particularly in vascular repair.

[Nasopharyngeal teratomas (a case report and review of the literature)].

Objective: To investigate the clinical characteristics of nasopharyngeal teratomas (NPT), improve the diagnosis and treatment of the disease.

Method: We reported a 14 years old girl with NPT, and reviewed the literatures.

Result: NPT was transorally expected under nasal endoscope, no recurrence was found over a 5 year follow-up.

[Single-port laparoscopic ligation with suture silk for varicocele: a report of 20 cases].

Objective: To evaluate the clinical effect of single-port laparoscopic ligation (SPLL) with suture silk for the management of varicocele.

Methods: We analyzed the clinical effects of SPLL with suture silk in the treatment of 20 cases of varicocele, and compared them with those of conventional three-port laparoscopic ligation (TPLL) for another 24 varicocele patients.

Results: All the operations were successful.
