The microwave has been widely used in the field of biology with the development of microwave technology. Previous studies suggest that suitable doses of microwave irradiation improved plant metabolism and enzymatic activities under cadmium stress and enhanced cadmium tolerance in wheat seedlings. The objective of this study was to test whether nitric oxide(More)
The aim of this study was to investigate how patterns of lymph nodes recurrence after radical surgery impact on survival of patients with pT1-3N0M0 thoracic esophageal squamous cell carcinoma. One hundred eighty consecutive patients with thoracic esophageal squamous cell carcinoma underwent radical surgery, and the tumors were staged as pT1-3N0M0 by(More)
OBJECTIVE To investigate liver lobe volumes and the ratios of liver lobe volumes to spleen volume measured with magnetic resonance imaging (MRI) for quantitatively monitoring and staging liver fibrosis. METHODS Animal study was approved by Institutional Animal Care and Use Committee. Sixteen minipigs were prospectively used to model liver fibrosis, and(More)
OBJECTIVE To determine whether the gross tumor volume of resectable gastric adenocarcinoma on multidetector computed tomography could predict the presence of regional lymph node metastasis and could determine N categories. MATERIALS AND METHODS A total of 202 consecutive patients with gastric adenocarcinoma who had undergone gastrectomy 1 week after(More)
Abnormally hyperphosphorylated tau is the major protein constituent of neurofibrillary tangles (NFTs) in the brain of Alzheimer disease (AD) patients. Cell cycle reactivation is considered an important neuropathological feature of AD, and re-expression and activation of cell cycle regulators are known to occur in neurons containing NFTs. The aim of the(More)
Most hepatoma cell lines lack proper expression and induction of CYP3A4 enzyme, which limits their use for predicting drug metabolism and toxicity. Nuclear receptor pregnane X receptor (PXR) has been well recognized for its critical role in regulating expression of CYP3A4 gene. However, its physiological activity of binding to the particular site of(More)
OBJECTIVE To determine whether right liver lobe volume (RV) and spleen size measured utilizing magnetic resonance (MR) imaging could identify the presence and severity of cirrhosis in patients with hepatitis B. METHODS Two hundred and five consecutive patients with clinically confirmed diagnosis of cirrhosis due to hepatitis B and 40 healthy control(More)
OBJECTIVE To investigate the associations of ectopic blood supply of hepatocellular carcinoma (HCC) with its morphological features and therapeutic history. METHODS Three hundred and six patients with 373 HCC lesions were enrolled in this study, and underwent biphasic contrast-enhanced scans on a 64-section MDCT. The anatomy of ectopic blood supply,(More)
Bitespiramycin, a group of 4"-O-acylated spiramycins with 4"-O-isovalerylspiramycins as the major components, was produced by recombinant spiramycin-producing strain Streptomyces spiramyceticus harboring a 4"-O-acyltransferase gene. The experiment was initially performed in synthetic medium with 0.5 g l(-1) Valine, Isoleucine or Leucine feeding at 36 h(More)
