Carbon wet deposition flux and river carbon output in a forest watershed in permafrost region of the Da Xing'an Mountains.

Carbon wet deposition and river carbon output in river basins are important components of global carbon cycle. The assessment of both properties is of great significance for regional carbon budget. However, research on these topics in high-latitude permafrost regions in China is still lacking.

Rock fragments significantly affect the carbon and nitrogen distribution in the surface soil - Evidences from large number samples of soil rock fragment interfaces in a boreal forest watershed.

Rock fragments are widely distributed in soils. The material cycling and the physico-chemical processes of soil ecosystems are both inevitably spatially affected by rock fragments. However, the effect of rock fragments on the spatial distribution characteristics of soil carbon and nitrogen is still not well studied and understood.

The effect of polysaccharide on the physical and healing properties of curdlan-based hydrogel for wound healing.

polysaccharide (BSP) was added to curdlan to form a blend hydrogel through a simple heating-cooling procedure to improve the hydrophilicity and healing efficacy of curdlan-based hydrogel used in wound healing. We explored the interplay between BSP and curdlan, studied how BSP concentration affects the physical properties and microstructures of hydrogels, and examined the biocompatibility and healing properties of the blend hydrogel. It was proved that the hydrogel framework was primarily formed by ordered arranged curdlan molecules, with BSP uniformly dispersed and intertwined with curdlan through hydrogen bonding.

Characterization and evaluation of polysaccharide/konjac glucomannan blend hydrogel for wound healing.

polysaccharide (BSP) is effective for wound healing and has important applications in health care. A series of blend hydrogels was designed with BSP and konjac glucomannan (KGM) in this study to overcome the deficient mechanical performance caused by the excessive dissolution of BSP without affecting its physiological activity. The interplay between them, as well as the effects of KGM concentration on the physical properties and microstructures of hydrogels, were also explored.

Characteristics and Factors Associated with Ability of Caregivers to Care for Hemodialysis Patients.

BACKGROUND The care ability of caregivers markedly impacts the patient' s quality of life and such ability may be influenced by various factors. This study aimed to explore the factors affected the care ability of caregivers for hemodialysis patients. MATERIAL AND METHODS This cross-sectional study involved 271 caregivers of hemodialysis patients.

[Characteristics of nitrogen wet deposition and flux with runoff during the spring freeze-thaw period in permafrost region watershed of Da Hinggan Mountains, Northeast China].

Nitrogen (N) transport is an important component of a watershed's nutrient cycle, which has significant impacts on global nitrogen cycle. In this study, we measured precipitation and daily stream N concentrations during the spring freeze-thaw period (April 9-June 30, 2021) in a small forest watershed (Laoyeling) in the permafrost region of Da Hinggan Mountains to calculate wet N deposition and stream N flux. The results showed the wet deposition fluxes of ammonium, nitrate, and total N were 695.

Impacts of permafrost thaw on streamflow recession in a discontinuous permafrost watershed of northeastern China.

Permafrost thaw due to climate change is altering terrestrial hydrological processes by increasing ground hydraulic conductivity and surface and subsurface hydrologic connectivity across the pan-Arctic. Understanding how runoff responds to changes in hydrologic processes and conditions induced by permafrost thaw is critical for water resources management in high-latitude and high-altitude regions. In this study, we analyzed streamflow recession characteristics for 1964-2016 for the Tahe watershed located at the southern margin of the permafrost region in Eurasia.

Recanalization of thrombosed aneurysmal hemodialysis arterovenous fistulas using a hybrid technique based on data from a single center.

Objective: To explore the technical specifications and clinical outcomes of thrombosed aneurysmal haemodialysis arteriovenous fistula (AVF) treated with ultrasound-guided percutaneous transluminal angioplasty combined with minimal aneurysmotomy.

Methods: This case series study included 11 patients who had thrombosed aneurysmal AVF and underwent salvage procedures over a 13-month period. All procedures were performed under duplex guidance.

Transcriptional Comparison Investigating the Influence of the Addition of Unsaturated Fatty Acids on Aroma Compounds During Alcoholic Fermentation.

The levels of unsaturated fatty acids (UFAs) in grape must significantly influence yeast metabolism and the production of aroma compounds. In this work, cDNA microarray technology was applied to analyze the transcriptional discrepancies of wine yeast (commercial wine yeast Lalvin EC1118) fermenting in synthetic grape must supplemented with different concentrations of a mixture of UFAs (including linoleic acid, oleic acid, and α-linolenic acid). The results showed that the initial addition of a high level of UFAs can significantly enrich the intracellular UFAs when compared to a low addition of UFAs and further increase the cell population and most volatiles, including higher alcohols and esters, except for several fatty acids.

Effect of training systems on fatty acids and their derived volatiles in Cabernet Sauvignon grapes and wines of the north foot of Mt. Tianshan.

C6 and C9 volatiles, originated from fatty acids, are important volatiles for 'Cabernet Sauvignon' grapes and wines. This study evaluated the influence of different training systems including Modified Vertical Shoot Positioned, (M-VSP); Fan training system with two trunks (F-TT); Fan training system with multiple trunks (F-MT) on these volatiles and the long-chain fatty acids (>C12) of grape berries and wines in the northwest of China. The expression profiles of genes from associated metabolic pathway were also analyzed.
