Macrolepiota procera, one of edible mushrooms belongs to Agaricaceae of Basidiomycota, has a good taste and good medicinal value. As a preliminary study for the development of artificial cultivation method of edible mushroom, cultural characteristics of M. procera was investigated on various culture media under different environmental conditions. Mycelial(More)
OBJECTIVES Polymorphisms of genes from glutathione S-transferases (GSTs) and N-acetyltransferase 2 (NAT2) have been associated with increased susceptibility to various cancers. Previous results showed that East Asians such as Koreans, Japanese and Chinese have a much higher frequency of the GSTM1 and GSTT1 null genotypes and NAT2 rapid acetylator type.(More)
Acute spinal cord injury (SCI) is two-step process that first involves the primary mechanical injury and then the secondary injury is induced by various biochemical reactions. Apoptosis is one of secondary SCI mechanisms and it is thought to play an important role for the delayed neuronal injury. The enhanced formation of nitric oxide (NO) via inducible(More)
We have cloned genes involved in the initial stage of fruit development in the melon by suppression subtractive hybridization. A cDNA library of unfertilized ovules was subtracted from that of fruit 9 days after pollination (DAP); 10 of the 40 selected cDNA clones were identified by reverse Northern analysis as genes differentially expressed in fruit at 9(More)
The hypermethylation of the CpG islands is a common mechanism for the inactivation of tumor-related genes. In the present study, we analyzed the methylation status of genes for cell repair such as hMLH1, MGMT, and GSTP1, and a gastric cancer-specifically methylated DNA fragment, MINT 25 in gastric cancer cases and control groups. The study population(More)
The gene previously designated as putative cyclodextrinase from Thermotoga maritima (TMG) was cloned and overexpressed in Escherichia coli. The recombinant TMG was partially purified and its enzymatic characteristics on various substrates were examined. The enzyme hydrolyzes various maltodextrins including maltotriose to maltoheptaose and cyclomaltodextrins(More)
PURPOSE The objectives of this study were measure the orbital volume of healthy Koreans and analyze the differences between orbital tissue volume with respect to age and sex and to assess any correlation between body mass index (BMI), eyeball position, and orbital volume. METHODS We retrospectively evaluated the scan results of patients who had undergone(More)
PURPOSE The objective of this study was to report the cause of increased contrast sensitivity and improved functional visual acuity after upper eyelid blepharoplasty. METHODS Twenty-two eyelids of 16 patients with dermatochalasis and involutional ptosis were prospectively studied. Contrast sensitivity, corneal topography, high-order aberration (HOA), and(More)
PURPOSE The objective of this study was to evaluate the association of facial asymmetry and nasal septal deviation in acquired unilateral nasolacrimal duct (NLD) obstruction. METHODS A retrospective survey was conducted of 39 patients (6 male and 33 female) who had undergone endoscopic dacryocystorhinostomy at the Korea University Ansan Hospital. Patients(More)
PURPOSE The aim of this study was to evaluate the effectiveness of simultaneous lateral tarsal strip procedure (LTS) and endonasal dacryocystorhinostomy (DCR) for the treatment of nasolacrimal duct obstruction and lower lid laxity. METHODS We conducted a retrospective, interventional study of concurrent DCR with LTS for patients with nasolacrimal duct(More)
