Public concern and metabolic drain were the main driving forces for the development of a selectable marker-free transformation system. We demonstrated here the production of transgenic tobacco plants using a non-selection approach by Agrobacterium tumefaciens-mediated transformation. A. tumefaciens-infected leaf explants were allowed to produce shoots on a(More)
BACKGROUND Carcinoma of the right colon invading the pancreas or duodenum is rare. Evidence of the indication, operative morbidity, and survival of en bloc pancreaticoduodenectomy and right colectomy for right colon cancer invading adjacent organs is limited. OBJECTIVE : The goal of this study was to investigate the feasibility, safety, indication, and(More)
The human immunodeficiency virus type 1 (HIV-1) can interact with and exploit the host cellular machinery to replicate and propagate itself. Numerous studies have shown that the Mitogen-activated protein kinase (MAPK) signal pathway can positively regulate the replication of HIV-1, but exactly how each MAPK pathway affects HIV-1 infection and replication is(More)
(−)-Epigallocatechin-3-gallate (EGCG) is the most abundant catechin in green tea. In this study, we found that hepatitis C virus (HCV) infection was significantly suppressed by EGCG in an HCV cell culture (HCVcc) system using a JFH1-GFP chimeric virus, with a 50 % effective concentration (EC50) of 17.9 μM. The inhibitory activity of EGCG was confirmed by(More)
AIM To evaluate a mixed micellar drug delivery system composed of sodium cholate and phospholipid for oral administration of silybin, a promising hepatoprotectants. METHODS The optimum formulation of sodium cholate/phospholipid-mixed micelles containing silybin was obtained based on the study of pseudo-ternary phase diagram. The dissolution of(More)
TRIM5α has been identified as the main restriction factor responsible for resistance of Old World monkey cells to HIV-1 infection. The precise mechanism of viral inhibition by TRIM5α remains elusive but appears to occur in multiple ways. Here, we report that rhesus monkey TRIM5α (TRIM5α(rh)) can represses HIV-1 LTR promoter activity by negatively regulating(More)
Outer membrane (OM) proteins play a significant role in bacterial pathogenesis. In this work, we examined and compared the expression of the OM proteins of the rice pathogen Acidovorax avenae subsp. avenae strain RS-1, a Gram-negative bacterium, both in an in vitro culture medium and in vivo rice plants. Global proteomic profiling of A. avenae subsp. avenae(More)
Pyrrolidine enones, derived from 3-oxo pyrrolidine 2-phosphonates and a HWE reaction with aldehydes, on Luche reduction give pyrrolidine allylic alcohols. The alcohols on hydrogenation (Pd/H2) give cis-2,5-disubstituted pyrrolidines and on treatment with TFA-NaBH3CN undergo a hydroxy directed reduction to trans-2,5-disubstituted pyrrolidines.
INTRODUCTION The feasibility and safety of pancreaticoduodenectomy (PD) combined with long segmental mesentericoportal vein (MPV; >5 cm) resection and end-to-end anastomosis without graft has rarely been demonstrated. MATERIALS AND METHODS Eight patients with pancreatic head adenocarcinoma underwent PD combined with long MPV resection between August 2006(More)
Na+-dependent glucose cotransporter (SGLT1), reported overexpression in tumor tissues while its clinical significance was not established, and epidermal growth factor receptor (EGFR) with potential relation to SGLT1 were studied in order to investigate their clinical significance in colorectal cancer (CRC). Eighty-five patients of CRC who received(More)
