Bioenergy from dairy manure: technologies, challenges and opportunities.

Dairy manure (DM) is a kind of cheap cellulosic biomass resource which includes lignocellulose and mineral nutrients. Random stacks not only leads damage to the environment, but also results in waste of natural resources. The traditional ways to use DM include returning it to the soil or acting as a fertilizer, which could reduce environmental pollution to some extent.

Cervus and cucumis peptides ameliorates bone erosion in experimental arthritis by inhibiting osteoclastogenesis.

Objective: Rheumatoid arthritis is an autoimmune disease characterised by inflammation and bone loss, leading to joint destruction and deformity. The cervus and cucumis polypeptide (CCP) injection, one of the traditional Chinese medicine injections combined extracts from deer horn and sweet melon seeds, is widely used to treat arthritis and bone fracture in China. The present study investigated the therapeutic efficacy and mechanism of CCP on pathological immune cells and bone homoeostasis in rodent experimental arthritis.

Artemisinin analogue SM934 ameliorates DSS-induced mouse ulcerative colitis via suppressing neutrophils and macrophages.

Ulcerative colitis (UC) is a chronic, nonspecific inflammatory bowel disease (IBD) characterized by complicated and relapsing inflammation in the gastrointestinal tract. SM934 is a water-soluble artemisinin analogue that shows anti-inflammatory and immuno-regulatory effects. In this study, we investigated the effects of SM934 on UC both in vivo and in vitro.

Application of sequential extraction analysis to Pb(II) recovery by zerovalent iron-based particles.

Zerovalent iron (ZVI) is an environmental-friendly reactive reagent for recovering heavy metals. However, the detailed recovery mechanism remains unclear due to a lack of quantitative analysis of recovery products. Herein, microscale ZVI, nanoscale ZVI and Ni/Fe nanoparticles were used to recover Pb(II) in aqueous solution and a sequential extraction procedure (SEP) was applied to determine the formed lead species quantitatively.

Spiroorthoester group-containing pregnane glycosides from the root barks of Periploca chrysantha and their inhibitory activities against the proliferation of B and T lymphocytes.

Phytochemical investigation of the root barks of Periploca chrysantha D. S. Yao, X.

Cascarinoids A-C, a Class of Diterpenoid Alkaloids with Unpredicted Conformations from Croton cascarilloides.

Cascarinoids A-C (1-3), a new class of diterpenoid alkaloids with unpredicted conformations, were isolated and structurally characterized from Croton cascarilloides. It was demonstrated that the dispersion interaction might be one of the main contributors that stabilized the folded conformations for compounds 1-3. Compounds 2 and 3 showed moderate immunosuppressive activity against T and/or B lymphocyte cells.

C-steroidal glycosides and sesquiterpenes from the roots of Cynanchum bungei and their inhibitory activities against the proliferation of B and T lymphocytes.

Phytochemical investigation of the roots of Cynanchum bungei Decne (Asclepiadaceae) led to the elucidation of seven C-steroidal glycosides (1-7) including three new compounds (1-3), named cynabungosides A-C, one new eudesmane-type sesquiterpene (8), named cynabungone, and one new humulane-type sesquiterpene (9), named cynabungolide. Their structures were elucidated on the basis of extensive spectroscopic analysis. The absolute configurations of 8 and 9 were defined unequivocally by ECD analysis and X-ray crystallography, respectively.

(5R)-5-hydroxytriptolide ameliorates anti-glomerular basement membrane glomerulonephritis in NZW mice by regulating Fcγ receptor signaling.

(5R)-5-hydroxytriptolide (LLDT-8) is a novel triptolide analog that has been identified as a promising candidate for treating autoimmune diseases and has been shown to be effective in treating murine collagen-induced arthritis and lupus nephritis. In the present study, we investigated the therapeutic effect and possible mechanism of action of LLDT-8 in a murine anti-glomerular basement membrane (GBM) glomerulonephritis model. NZW mice were injected with rabbit anti-GBM serum (500 μL, ip).

Long-term outcomes of vaginoplasty with autologous buccal micromucosa.

Objective: To evaluate the technical feasibility and anatomical and functional outcomes of one-stage vaginoplasty with autologous buccal micromucosa.

Methods: We retrospectively reviewed our experiences with 38 patients with vaginal agenesis treated with primary surgery from June 2006 to April 2012. All patients underwent transvestibular vaginoplasty with autologous buccal micromucosa.

[Survey on the transmission of HIV drug resistance in Kunming, Yunnan province in 2010].

Objective: To study the HIV drug resistance (HIVDR) transmission in Kunming city of Yunnan province in 2010.

Methods: Referring to the guidelines for HIV drug resistance threshold survey (HIVDR-TS) set by WHO, 62 plasma samples of recently reported HIV-infected individuals who were older than 25 years of age, were collected from January to August 2010. Genotyping of pol genetic mutations associated with HIVDR with reverse transcriptional PCR was performed and the prevalence of HIV-1 drug resistance transmission was evaluated.

[Optimization of acrylic fiber polymerization wastewater treatment condition by three-dimensional electrode].

The research was focus on the influence of experimental conditions to the removal efficiency of contaminant and the change of biodegradability in the treatment of acrylic fiber polymerization wastewater using three-dimensional electrode reactor with granular activated carbon. The anode was Ti/SnO2-Sb2O3 expanded metal sheet electrode. The cathode was Ti expanded metal sheet electrode.
