Dual anti-angiogenic and anti-inflammatory action of tRNA-Cys-5-0007 in ocular vascular disease.

Background: Intravitreal injections of angiogenesis inhibitors have proved efficacious in the majority of patients with ocular angiogenesis. However, one-fourth of all treated patients fail to derive benefits from intravitreal injections. tRNA-derived small RNA (tsRNA) emerges as a crucial class of non-coding RNA molecules, orchestrating key roles in the progression of human diseases by modulating multiple targets.

[Applicability of cosmic-ray neutron sensing for monitoring soil moisture in farmland].

Cosmic-ray neutron sensing (CRNS) method was recently used to monitor soil moisture in farmland. But its spatial representation and accuracy needs further study. A field experiment was carried out to evaluate the applicability of CRNS for monitoring soil moisture in winter wheat farmland of the North China Plain.

[Effects of the blended nitrogen fertilizers combined with inhibitors on soil nitrogen pools.].

Pot experiment with winter wheat was conducted to investigate the effects of blended nitrogen (N) fertilizer (slow-release fertilizer-N:urea-N=1:1) combined with N fertilizer inhibitor NAM on soil ammonium (NH-N), nitrate (NO-N), microbial biomass nitrogen (MBN) and fixed-ammonium (FN) contents. We analyzed dynamic characteristics of soil mineral N, MBN, FN pools under different treatments. There were six treatments, including no N fertilizer (CK), conventional urea (U), blended N fertilizer (MU), MU plus 2.

The association of the optimal bolus of dexmedetomidine with its favourable haemodynamic outcomes in adult surgical patients under general anaesthesia.

Aims: Dexmedetomidine is highly specific α2-adrenoceptor agonist. A single bolus of dexmedetomidine can achieve clinical therapeutic effect. Therefore, it is essential to know the safety margin between the clinical effectiveness dosages of dexmedetomidine and its side effect.

[Preparation and characterization of wood/methylolurea composite with in-situ polymerization].

Wood/methylolurea composite was prepared with the in-situ polymerization. The green timber with high moisture content was impregnated by a pulse-dipping machine and then was dried in a hot-press drying kiln. The cross-linking reaction was taken under the heat treatment between the wood modifier and the wood composition, including cellulose, hemicelluloses, and lignin.

[The influence of reference data noise on the NIR prediction results].

This article used hemicelluloses content in acacia spp. wood as a case study to demonstrate the influence of noise in the reference data on the results of NIR calibration model. The results indicated that the accuracy of NIR calibration model was affected by the reference data noise.

[Preparation and properties of wood/modified UF prepolymer composite materials].

In the present research, the urea-formaldehyde prepolymer and multilayer hot-press drying were used to modify poplar plantation. The prepolymer was impregnated into cell lumen space by pulse-dipping machine. Then the timbers were compressed and dried by the multilayer hot-press drying kiln.

[Extending hemicelluloses content calibration of Acacia spp using NIR to new sites].

In this research, hemicellulose contents of 78 wood meal samples of Acacia spp trees grown in Guangxi and another 33 wood meal samples of Acacia spp trees grown in Fujian were measured by wet chemistry. NIR spectra were also collected by a Bruker MPA spectrometer within 4 000-12 500 cm(-1) of wavenumbers using a standard sample cup. Equations were developed using partial least squares (PLS) regression and cross validation for multivariate calibration in this study.

[Effects of alprostadil and ulinastatin on inflammatory response and lung injury after cardiopulmonary bypass in pediatric patients with congenital heart diseases].

Objective: To investigate the therapeutic effects of alprostadil (Lipo-PGE1) and Ulinastatin on inflammatory response and lung injury after cardiopulmonary bypass (CPB) in pediatric patients with congenital heart diseases.

Methods: 58 children with congenital heart diseases, including atrial septal defect, ventricular septal defect, and atrioventricular septal defect, scheduled to undergo CPB, aged 4 - 72 months, were randomly divided into 4 groups: alprostadil Group P (n = 15) receiving alprostadil 10 ng/ml added into the prime solution and continuous pump infusion of alprostadil 10 ngxkg(-1)xmin(-1) via central vein until the end of operation, Group U (n = 15) receiving ulinastatin 20 000 U/kg divided into several doses to be added into the prime solution, Group PU (n = 14) receiving alprostadil and ulinastatin according to the above protocols, and Group C (control group, n = 14) receiving normal saline of the equal volume. Electrocardiogram (ECG), heart rate (HR), pulse oxygen saturation (SpO(2)), and mean arterial pressure (MAP) were continuously monitored during operation.
