Biological nitrogen fixation is a complex process requiring multiple genes working in concert. To date, the Klebsiella pneumoniae nif gene cluster, divided into seven operons, is one of the most studied systems. Its nitrogen fixation capacity is subject to complex cascade regulation and physiological limitations. In this report, the entire K. pneumoniae nif(More)
AIM 1) To evaluate the effect of prostaglandin E2 (PGE2) on the regulation of vascular endothelial growth factor (VEGF) expression in gastric MKN28 cells, and 2) to investigate the role of the epidermal growth factor receptor (EGFR) signal transduction pathway in any effect exerted by PGE2 on VEGF expression. METHODS MKN28 cells were incubated with the(More)
BACKGROUND Consolidated bioprocessing (CBP), integrating cellulase production, cellulose saccharification, and fermentation into one step has been widely considered as the ultimate low-cost configuration for producing second-generation fuel ethanol. However, the requirement of a microbial strain able to hydrolyze cellulosic biomass and convert the resulting(More)
Seventeen novel 3-methyl-4-oxo-3,4-dihydroimidazo[5,1-d][1,2,3,5]tetrazine-8-carboxylate and -carboxamide derivatives were synthesized and evaluated for their growth inhibition in seven human solid tumor and a human leukemia HL-60 cell lines. Compound IVa showed more activity than the other compounds and the positive control temozolomide. In the presence of(More)
OBJECTIVE Human selenoprotein P (HSelP) is unique protein that contains 10 selenocysteines encoded by 10 inframe UGA, which typically function as stop codon. The function of HSelP remains unclear, in part due to the inability to express it by gene recombinant technique. This study is to investigate expression and purification of recombinant HSelP in(More)
OBJECTIVE To explore the relationship of occupational injuries with social and economic factors in chemical industry during 2000.01 - 2001.12. METHOD 1:2 paired case-control study, univariable logistic regression analysis, principal component analysis, and multiple logistic regression analysis were used in this study. RESULTS Univariable analysis showed(More)
BACKGROUND & OBJECTIVE Sep15 is a selenium-containing protein identified in 1998. This protein may be involved in cancer etiology and it may have redox function. The objective of this study was to investigate the relationship between the redox function of Sep15 and tumor development. METHODS The full-length DNA sequence of Sep15 was obtained by RT-PCR and(More)
AIMS AND OBJECTIVES The aim of this study was to improve the postoperative handover process and immediate postoperative patient outcomes. The objective was to implement a postoperative handover protocol in the neurosurgical intensive care unit of a tertiary teaching hospital. BACKGROUND Postoperative handover is a multidisciplinary collaborative medical(More)
From July 2003 to July 2009, 15 cases of subdural hematoma with swirl signs were treated in our hospital and their clinical data were retrospectively analysed. The mortality was compared between these patients and those with typical acute subdural hematoma who were treated at the same time in our hospital. Among the 15 cases, full recovery was achieved in 4(More)
This study was aimed to investigate whether hydroquinone (HQ) can inhibit NF-kappaB expression activated by phorbol myristate acetate (PMA), and to explore the relationship between the mechanism and the hematology toxicity of benzene tentatively. The human bone marrow stromal cells (BMSC) were harvested by in vitro culture and their change of morphology(More)
