Process and mechanism of termite impact on soil and plant.

Termites, as a kind of nesting social insects, are often confused as worldwide "pests" because some of their groups have great destructive effects. The vast majority of termites can regulate ecosystem functions and ser-vices by participating in biogeochemical cycles, known as "ecosystem engineers". We reviewed studies on the effects of termites on the physical, chemical and biological characteristics of mound soil ecosystems and the composition and diversity of plant communities.

Carbon dynamics in the deciduous broadleaf tree Erman's birch (Betula ermanii) at the subalpine treeline on Changbai Mountain, Northeast China.

Premise Of The Study: The growth limitation hypothesis (GLH) and carbon limitation hypothesis (CLH) are two dominant explanations for treeline formation. The GLH proposes that low temperature drives the treeline through constraining C sinks more than C sources, and it predicts that non-structural carbohydrate (NSC) levels are static or increase with elevation. Although the GLH has received strong support globally for evergreen treelines, there is still no consensus for deciduous treelines, which experience great asynchrony between supply and demand throughout the year.

Photoprotective and antioxidative mechanisms against oxidative damage in Fargesia rufa subjected to drought and salinity.

Drought and salinity are the two most common and frequently co-occurring abiotic stresses limiting plant productivity worldwide, yet it remains unclear whether bamboo species possess effective mechanisms to protect against oxidative damage caused by drought and salinity, either alone or in combination. In this study, we utilised Fargesia rufa Yi, a species important to forest carbon sequestration and endangered giant pandas, to evaluate physiological, biochemical and ultrastructural responses to drought, salinity and their combination. Under drought alone, F.

Detection of auto antibodies and transplantation of cultured autologous melanocytes for the treatment of vitiligo.

The aim of the present study was to establish an immunofluorescence method of antibody detection to identify melanocytes in the serum of vitiligo patients. Furthermore, we aimed to establish a method for the culture and proliferation of autologous pure melanocytes and to observe the effect of their transplantation for the treatment of vitiligo. Suspension of epidermal cells with melanocytes was performed using trypsin digestion of normal epiderm from eyelid operation and melanocytes were selectively cultured and proliferated in serum-free M2 medium.

Arthroscopy-Assisted Surgery for Acute Ankle Fractures: A Systematic Review.

Purpose: To summarize the clinical findings of adult patients undergoing arthroscopy-assisted open reduction-internal fixation for acute ankle fractures.

Methods: A systematic electronic search of the PubMed databases was performed for all published literature on December 8, 2014. All English-language clinical studies on acute ankle fractures treated with arthroscopy-assisted open reduction-internal fixation were eligible for inclusion.

Arthroscopy-assisted surgery for tibial plateau fractures.

Purpose: This study aimed to summarize the recent clinical outcomes of patients undergoing arthroscopy-assisted reduction and internal fixation (ARIF) for tibial plateau fractures.

Methods: A systematic electronic search of the PubMed and Cochrane databases was performed in January 2014. All English-language clinical studies on tibial plateau fractures treated with ARIF that were published after January 1, 2000 were eligible for inclusion.

[Distributions and influencing factors of total dissolved inorganic antimony in the coastal area of Zhejiang and Fujian].

Antimony has been ubiquitously present in the aquatic environment as a toxic and rare metalloid element. The contamination of antimony and its compounds in the environment is increasingly severe, so it has been received extensive attention by the international scientific community. The cruise was carried out in the coastal area of Zhejiang and Fujian provinces in the East China Sea (ECS) in May 2008.

[Abundance and biomass of planktonic ciliates in the shelf of East China Sea in spring and autumn].

An investigation was made on the abundance and biomass of planktonic ciliates in the shelf of East China Sea in May (spring) and November (autumn), 2011. The abundance of the ciliates in spring and autumn was averagely (614 +/- 861) and (934 +/- 809) ind x L(-1), and the biomass was averagely (1.70 +/- 3.

Metabolomic profiling for identification of potential biomarkers in the protective effects of modified Sinisan against liver injury in dimethylnitrosamine treated rats.

Metabolomics is a new platform based on the comprehensive analysis of low molecular weight metabolites and provides a powerful approach to discover biomarkers in biological systems. Modified Sinisan (MSNS), a traditional Chinese medicine formula, displayed bright prospects in the prevention and therapy of liver injury. However, its molecular mechanism of hepatoprotective effects remains unclear.

[Expression and activity of tissue-type plasminogen activator mutant reteplase with deletion of PAI-1 binding sites].

Aim: To construct a mutant of human tissue plasminogen activator (t-PA) with activity not inhibited by plasminogen activator inhibitor-1 (PAI-1).

Methods: The finger, epidermal growth factor and kringle-1 domains were removed from native t-PA to obtain a t-PA mutant with the PAI-1 binding sites. A pUC18 plasmid containing the human t-PA full-length cDNA sequence was used as template, and the DNA sequences encoding 1-3 and 176-527 amino acids were amplified by PCR.

[Prokaryotic expression of DnaJ-homologous chaperon PBP and preparation of rabbit antibody against PBP].

Aim: To express DnaJ-homologous chaperon peripherin-binding protein(PBP) gene in E.coli and prepare the rabbit antibody against PBP.

Methods: The PBP cDNA was amplified from the human fetal brain tissue by RT-PCR.

[Myocardial ultrastructural changes in rats following different levels of acute +Gz exposure].

Objective: To observe the effects of different levels of acute +Gz exposure on myocardial ultrastructure of rats and provide experimental basis for further development of anti-G measures.

Method: Twenty male Wistar rats were randomly divided into 4 groups (n=5): normal control group, +20 Gz group, +10 Gz group and +5 Gz group. Profile of the centrifuge +Gz exposure was trapezoidal, in which +20 Gz lasted for 30 s, +10 Gz for 1.

[Cloning of a DnaJ homolog chaperon PBP and its subcellular localization].

Aim: To isolate and identify a human DnaJ homolog chaperon, PBP, from a human skeleton cDNA library, and to analyze its expression and distribution in transfected mammalian cells.

Methods: (32)p-dCTP labeled probe hybridization was used to screen the human skeleton cDNA library and sequence of the positive clones were analyzed. Then PBP gene was transfected into COS-7 cells using lipofectamin.
