Pine sawdust pyrolysis was carried out respectively using microwave and conventional electrical heating at different temperatures in order to understand the properties of pyrolytic products from microwave pyrolysis of biomass. Less char material was obtained by microwave pyrolysis compared to conventional heating at the same temperature. While comparing the(More)
ETHNOPHARMACOLOGICAL RELEVANCE Libanotis buchtormensis is the source of an important traditional medicine from Shaanxi province of China used in the treatment of many illnesses. Libanotis buchtormensis supercritical extract (LBSE) has analgesic, sedative and anti-inflammatory qualities. Osthole is one of the major bioactive components of LBSE; it is known(More)
Candida dubliniensis is an important human fungal pathogen that causes oral infections in patients with AIDS and diabetes mellitus. However, C. Dubliniensis has been frequently reported in bloodstream infections in clinical settings. Like its phylogenetically related virulent species C. albicans, C. Dubliniensis is able to grow and switch between yeast form(More)
OBJECTIVE To study the effects of transforming growth factor-β1 (TGF-β1) on the gene expression of connective tissue growth factor (CTGF) in cultured lung fibroblasts of embryonic rats in vitro. METHODS Wistar rats of embryonic 19 days were used for primary culture of lung fibroblasts (LFs). The cells in the experimental group were treated by different(More)
The association of methylenetetrahydrofolate reductase (MTHFR) polymorphisms with multiple myeloma (MM) risk has been explored, but the results remain controversial. Thus, a meta-analysis was performed to provide a comprehensively estimate. The case-control studies about MTHFR C677T and A1298C polymorphisms with MM risk were collected by searching PubMed,(More)
BACKGROUND & OBJECTIVE Recent study found psychosocial factors play some important roles in carcinogenesis and development of malignant tumors, but its mechanisms remain unclear. This study was to investigate the impact of chronic restraint stress on splenocyte immunity and growth of mouse forestomach carcinoma (MFC) xenografts in Kunming mice, and provide(More)
This study aims to understand the mechanism of bio-oil gasification and the influence of operating parameters on the properties of the gas products. Firstly, the pyrolysis/gasification of bio-oil was performed using a thermogravimetric analyzer (TGA). The evaporation of gas products from bio-oil were measured on-line with coupled Fourier Transform Infrared(More)
OBJECTIVE To investigate the efficacy of CO2 laser combined with 32P-patch contact brachyradiotherapy for the treatment of keloids. METHODS From 2001 to 2006, 121 cases with 151 keloids, which reoccurred after treatment with more than 2 methods, underwent continuous CO2 laser treatment to remove the hypertrophic scar tissue, following by ultra-pulse CO2(More)
Suppressor of cytokine signaling (SOCS) is a new family of proteins produced in cells. It may play an important role in classic negative feedback loop to regulate cytokine signal transduction. SOCS-1 was observed and confirmed firstly. Expression of SOCS-1 can inhibit cytokine signal transduction of some cytokines, such as IL-6, LIF, OSM, INF-gamma, GH, and(More)
In order to study whether plasma can affect the structure and function of red blood cells during their storage period, the differences of pH value, concentration of K(+), Na(+), osmotic fragility, plasma hemoglobin, AchE, ATP, 2.3-DPG, P50 in suspended RBC, washed RBC, and RBC with various plasma volume at different storage times were compared. The results(More)
