[Effects of Straw Returning with Lime on SOC and Carbon Pool Management in Acidic Paddy Soil].

Soil acidification and low SOC are the main limiting factors in acidic paddy soils. Straw returning with lime is an effective measure to alleviate soil acidification and improve soil fertility; however, its interaction effects on SOC and carbon pool management are still unclear. To investigate the impact of straw returning with lime on the organic carbon pool of acidic paddy soil, field experiments were conducted on acidic paddy soil in Baiyun District and Huiyang District of Guangdong Province.

Heterogeneity of cannabinoid ligand-induced modulations in intracellular Ca signals of mouse pancreatic acinar cells in vitro.

We recently reported that a CBR agonist, GW405833 (GW), reduced both the ACh-induced Ca oscillations and the L-arginine-induced Ca signal enhancement in mouse pancreatic acinar cells, suggesting that GW-induced inhibition may prevent the pathogenesis of acute pancreatitis. In this study, we aim to evaluate the effects of other cannabinoid ligands on Ca signaling in acinar cells. Patch-clamp whole-cell recordings were applied to measure ACh-induced intracellular Ca oscillations in pancreatic acinar cells acutely dissociated from wild-type (WT), CBR knockout (KO), and CBR KO mice, and the pharmacological effects of various cannabinoid ligands on the Ca oscillations were examined.

[Dynamic monitoring and analysis of ecological environment in Weinan City, Northwest China based on RSEI model].

Based on the data of remote sensing images from Landsat in 1995 and 2015, this paper used the principal component analysis (PCA) method to determine the weights of four ecological indexes (greenness, dryness, wetness and heat), and then selected a evaluation model of remote sensing based ecological index (RSEI) to monitor and analyze the ecological environment quality of Weinan City from 1995 to 2015. The results showed that the mean values of RSEI in Weinan City increased from 0.489 to 0.

[Study on Form of Ar/Air ICP and A Microwave Diagnostics Based on the Hβ Spectrum Broadening].

The ICP in closed quartz chamber is an effective solution to local stealth of aircraft. The attenuation of the electromagnetic wave is strongly affected by distribution of electron density in incidence direction. In this paper, an experiment that the planar ICP discharged in all-quartz chamber (30.

[Expression of intercellular adhesion molecule-1 and vascular cell adhesion molecule in cardiac allografts and significance thereof: experiment with rats].

Objective: To investigate the expression of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) in allograft with chronic rejection (CR) after heart transplantation.

Methods: Seventy-two SD rats receiving transplantation of the heats of 71 Wistar rats were divided into 4 equal groups: Group A, undergoing heterotopic cervical heart transplantation (transplanted with donor's heart subcutaneously at the neck) and receiving none intervention, and with the transplanted hearts taken out 3 d after transplantation to the end of CR; Group B, injected intravenously with the splenocytes (SPCs) of the donors on day 0, injected with cyclophomide (CP) on d2, transplanted with the donor hearts on d15, with the transplanted hearts taken out 15 - 120 days after transplantation; Group C, transplanted with the donor's heart and injected intraperitoneally with cyclosporine A (Cs A) 10 mg/kg every other day for 8 - 10 times, and with the transplanted hearts taken out 60 d after transplantation to the end of CR; and Group D, injected intravenously with the SPCs of the donors on day 0, injected with CP on d2, transplanted with the donor hearts on d15, with the transplanted hearts taken out 150 - 420 days after transplantation. Immunohistochemical method was used to detect the expression of ICAM-1 and VCAM-1 in the allografts.

[Application of one-way valved patch in treatment of patients with congenital heart disease with severe pulmonary hypertension].

Objective: To explore the effect of one-way valved patch used in congenital heart disease with severe pulmonary hypertension.

Methods: One-way valved patch was used in 30 patients of congenital heart disease with severe pulmonary hypertension (PP/PS > 0.75) in operation.
