Increasing plant diversity enhances soil organic carbon storage in typical wetlands of northern China.

Soil organic carbon plays an important role in climate change mitigation, and can be strongly affected by plant diversity. Although a positive effect of plant diversity on soil organic carbon storage has been confirmed in grasslands and forests, it remains unclear whether this effect exists in wetlands. In this study, we investigated plant diversity, soil properties and soil organic carbon across five typical wetlands of northern China, to test the effect of plant diversity on soil organic carbon and clarified the regulators.

Does genotypic diversity of affect CO and CH fluxes?

Biodiversity plays important roles in ecosystem functions and genetic diversity is a key component of biodiversity. While effects of genetic diversity on ecosystem functions have been extensively documented, no study has tested how genetic diversity of plants influences greenhouse gas fluxes from plant-soil systems. We assembled experimental populations consisting of 1, 4 or 8 genotypes of the clonal plant in microcosms, and measured fluxes of CO and CH from the microcosms.

Biochar-compost addition benefits Phragmites australis growth and soil property in coastal wetlands.

Salinity stress is common for plants growing in coastal wetlands. The addition of biochar in the soil may alleviate the negative effect of salinity through its unique physicochemical properties. To test this, we conducted a greenhouse experiment where the cosmopolitan wetland plant Phragmites australis was subjected to four salinity treatments (0, 5, 10 and 15‰) and three biochar treatments (no biochar addition, with biochar addition and with biochar-compost addition, both biochar and compost were made from P.

Biochar addition affects root morphology and nitrogen uptake capacity in common reed (Phragmites australis).

Nitrogen (N) is a key factor that limits plant growth in most terrestrial ecosystems, and biochar reportedly improves soil characteristics and grain yields. However, the effects of biochar on plant N uptake in wetland ecosystems and the underlying mechanisms of these effects remain unclear. Therefore, our study sought to characterise the effects of biochar addition on Phragmites australis N absorption rates at two different N deposition conditions [30 and 60 kg N hm yr; i.

Protective Role of Coenzyme Q10 in Acute Sepsis-Induced Liver Injury in BALB/c Mice.

Sepsis increases the risk of the liver injury development. According to the research works, coenzyme Q10 exhibits hepatoprotective properties in vivo as well as in vitro. Current work aimed at investigating the protective impacts of coenzyme Q10 against liver injury in septic BALB/c mice.

Biochar rhizosphere addition promoted Phragmites australis growth and changed soil properties in the Yellow River Delta.

Biochar addition can enhance plant growth and change soil physicochemical properties in saline soil. However, it is unclear whether the positioning of biochar additions (e.g.

Vasoactive intestinal peptide receptor-based imaging and treatment of tumors (Review).

Vasoactive intestinal peptide receptors (VIPRs) are members of the G-protein-coupled receptor superfamily. These receptors are overexpressed in many common malignant tumors and play a major role in the progression and angiogenesis of a number of malignancies. Therefore, VIPRs may be a valuable target for the molecular imaging of tumors and therapeutic interventions.

Imaging targeted at tumor with (188)Re-labeled VEGF(189) exon 6-encoded peptide and effects of the transfecting truncated KDR gene in tumor-bearing nude mice.

Introduction: Planar imaging of (188)Re-labeled vascular endothelial growth factor (VEGF)(189) exon 6-encoded peptide (QKRKRKKSRYKS) with single photon emission computed tomography (SPECT) in tumor-bearing nude mice and effects of the transfecting truncated KDR gene on its imaging were investigated, so as to provide a basis for further applying the peptide to tumor-targeted radionuclide treatment.

Methods: QKRKRKKSRYKS, coupling with mercaptoacetyltriglycine (MAG(3)) chelator was labeled with (188)Re; then in vivo distribution, planar imaging with SPECT and blocking experiment in tumor-bearing nude mice were analyzed. Recombinant adenovirus vectors carrying the truncated KDR gene were constructed to transfect tumor tissues to evaluate the effects of truncated KDR on the in vivo distribution and tumor planar imaging of (188)Re-MAG(3)-QKRKRKKSRYKS in tumor-bearing nude mice.

Effects of surface gastric pacing on gastric myoelectrical activity and plasma motilin in a canine model of gastric motility disorders.

Objective: To investigate the effects of surface gastric pacing on gastric myoelectrical activity and plasma motilin concentration in a canine model of gastric motility disorders.

Methods: Ten healthy mongrel dogs were divided into two groups: an experimental group of six dogs and control group of four dogs. The model of gastric motility disorders was established in the experimental group with truncal vagotomy combined with injection of glucagon.

Effects of gastric pacing on gastric emptying and plasma motilin.

Aim: To investigate the effects of gastric pacing on gastric emptying and plasma motilin level in a canine model of gastric motility disorders and the correlation between gastric emptying and plasma motilin level.

Methods: Ten healthy Mongrel dogs were divided into: experimental group of six dogs and control group of four dogs. A model of gastric motility disorders was established in the experimental group undergone truncal vagotomy combined with injection of glucagon.
