Many agarolytic bacteria degrade agar polysaccharide into the disaccharide unit neoagarobiose [O-3,6-anhydro-alpha-L-galactopyranosyl-(1-->3)-D-galactose] using various beta-agarases. Neoagarobiose hydrolase is an enzyme that acts on the alpha-1,3 linkage in neoagarobiose to yield D-galactose and 3,6-anhydro-L-galactose. This activity is essential in both(More)
3,6-Anhydro-l-galactose (L-AHG) constitutes 50 % of agarose, which is the main component of red macroalgae. No information is currently available on the mass production, metabolic fate, or physiological effects of L-AHG. Here, agarose was converted to L-AHG in the following three steps: pre-hydrolysis of agarose into agaro-oligosaccharides by using acetic(More)
We have designed a five-year multicentre prospective cohort study in women who are both human papillomavirus (HPV)-positive with either atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesion (LSIL) of cervix. This study aimed to analyze the risk of developing a high-grade squamous intraepithelial lesion(More)
The aim of this study was to investigate the association of central and abdominal obesity with the prevalence of cataracts in a middle-aged Korean population. This retrospective cross-sectional study was based on the data collected from the Korea National Health and Nutrition Examination Survey 2008-2009, in which 4,914 subjects were examined.(More)
OBJECTIVES The Republic of Korea reports approximately 35,000 new tuberculosis (TB) patients each year, and the number of HIV-infected individuals is steadily increasing. Public health centers (PHCs) conduct TB diagnosis and treatment for risk groups in communities. This study aimed to identify possible trends and characteristics of HIV infection among(More)
Sporadic Creutzfeldt-Jakob disease (CJD) is clinically characterized by rapidly progressive dementia combined with other cardinal symptoms, such as myoclonus, visual or cerebellar disturbances, extrapyramidal or pyramidal disturbance, and akinetic mutism. However, as an initial manifestation, focal neurologic deficits other than the aforementioned or(More)
Cerebral air embolism is an uncommon disorder, but it can result in significant morbidity and even mortality. Cerebral air embolism during esophago-gastro-duodenoscopy is also rare, but has in recent years been repeatedly reported. We report here a patient with cerebral infarction due to air embolism during endoscopic variceal ligation in liver cirrhosis.(More)
A correct diagnosis and a proper treatment may yield a rapid and simple cure for benign paroxysmal positional vertigo (BPPV). Although the Gufoni maneuver is widely used to treat apogeotropic horizontal-canal BPPV (HC-BPPV), few studies have clarified the relationship between the speed and intensity of maneuver execution and successful canalith reposition.(More)
