PURPOSE: Viral infections are involved in ~50% of exacerbations among Caucasian adult asthmatics. However, there have been few reports on the causative virus of exacerbations in Korean adult asthmatics. Thus, we compared frequencies and types of viruses between lower respiratory tract illnesses (LRTIs) with exacerbations (exacerbated LRTIs) and those without exacerbations (stable LRTIs) to evaluate contribution of respiratory viruses to exacerbations. METHODS: Viral RNA was extracted from sputum using the Viral Gene-spin™ Kit...

Avian leukosis virus (ALV) is a retrovirus that causes tumors in avian species, and its vertical and horizontal transmission in poultry flocks results in enormous economic losses. Despite the discovery of specific host receptors, there have been few reports on the modulation of viral susceptibility via genetic modification. We therefore engineered acquired resistance to ALV subgroup B using CRISPR/Cas9-mediated genome editing technology in DF-1 chicken fibroblasts. Using this method, we efficiently modified the tumor virus locus B (tvb) gene, encoding the TVB receptor, which is essential for ALV subgroup B entry into host cells...

Melatonin is known to improve cognitive deficits and its functions have been studied in various disease models, including Alzheimer's disease. In this study, we investigated effects of melatonin on cognition and the cholinergic system of the septum and hippocampus in a mouse model of scopolamine-induced amnesia. Scopolamine (1 mg/kg) and melatonin (10 mg/kg) were administered intraperitoneally to mice for 2 and 4 weeks. The Morris water maze and passive avoidance tests revealed that both treatments of scopolamine significantly impaired spatial learning and memory; however, 2- and 4-week melatonin treatments significantly improved the spatial learning and memory...

Inefficient transport of xylose into Saccharomyces cerevisiae is a major hurdle for production of xylitol, a natural sweetener with five carbons. To facilitate the xylose transport and hence increase xylose conversion to xylitol, the araE gene encoding an arabinose:H(+) symporter (AraE) from Bacillus subtilis and the XYL1 gene from Scheffersomyces stipitis were expressed in Saccharomyces cerevisiae EBY.VW4000, a hxt null mutant. The resulting strain of EXHA exhibited 4.1 fold increases in xylose consumption rate and xylitol productivity, relative to the control strain without AraE...

The DevSR (DosSR) two-component system, which is a major regulatory system involved in oxygen sensing in mycobacteria, plays an important role in hypoxic induction of many genes in mycobacteria. We demonstrated that overexpression of the kinase domain of Mycobacterium tuberculosis (Mtb) PknB inhibited transcriptional activity of the DevR response regulator in Mycobacterium smegmatis and that this inhibitory effect was exerted through phosphorylation of DevR on Thr180 within its DNA-binding domain. Moreover, the purified kinase domain of Mtb PknB significantly phosphorylated RegX3, NarL, KdpE, TrcR, DosR, and MtrA response regulators of Mtb that contain the Thr residues corresponding to Thr180 of DevR in their DNA-binding domains, implying that transcriptional activities of these response regulators might also be inhibited when the kinase domain of PknB is overexpressed...

Serum proteomics has been applied for the discovery and analysis of biomarkers related to human disease. Serum is an optimal source to identify proteins derived from diseased-tissue compartments. We recently established an integrative method to analyze highly basic proteins that remain unresolved by the general 2D-PAGE method. In this follow-up study, we successfully detected several disease-associated proteins from sera samples obtained from patients with atopic dermatitis (AD). After proteomic analyses, target proteins were validated from AD patient-derived sera using ELISA or Western blotting methods We detected zinc finger CCHC domain containing 10 (ZCCHC10), peptidoglycan recognition protein L (PGRP-L), kininogen, α-1-antitrypsin, and hornerin proteins that are dysregulated in AD patient sera samples, which suggest effective approaches to methodologically analyze the serum proteome...

BACKGROUND: Amoxicillin (Amx) is one of the most important antibiotics for eradication of Helicobacter pylori (H. pylori). Main determinants of genetically stable Amx resistance are mutations in the C-terminus of penicillin-binding protein 1A (pbp1A). However, contribution of individual mutation remains unclear. METHODS: 77 Amx-resistant (Amx(R) ) and 77 Amx-susceptible (Amx(S) ) H. pylori strains were isolated from gastric tissues, and DNA sequencing was performed to compare C-terminus sequences of pbp1A gene between Amx(R) and Amx(S) strains...

Gastric remnant necrosis after a subtotal gastrectomy is an extremely uncommon complication due to the rich vascular supply of the stomach. Despite its rareness, it must be carefully addressed considering the significant mortality rate associated with this condition. Patients vulnerable to ischemic vascular disease in particular need closer attention and should be treated more cautiously. When gastric remnant necrosis is suspected, an urgent endoscopic examination must be performed. We report a case of gastric remnant necrosis following a subtotal gastrectomy and discuss possible risk factors associated with this complication...
