    ABSTRACT: (S)-3-Hydroxybutyryl-CoA dehydrogenase from Clostridium butyricum (CbHBD) is an enzyme that catalyzes the second step in the biosynthesis of n-butanol from acetyl-CoA by the reduction of acetoacetyl-CoA to 3-hydroxybutyryl-CoA. The CbHBD protein was crystallized using the hanging-drop vapour-diffusion method in the presence of 2 M ammonium sulfate, 0.1 M CAPS pH 10.5, 0.2 M lithium sulfate at 295 K. X-ray diffraction data were collected to a maximum resolution of 2.3 Å on a synchrotron beamline. The crystal belonged to space group R3, with unit-cell parameters a = b = 148.5, c = 201.6 Å. With four molecules per asymmetric unit, the crystal volume per unit protein weight (VM) is 3.52 Å3 Da−1, which corresponds to a solvent content of approximately 65.04%. The structure was solved by the molecular-replacement method and refinement of the structure is in progress.

    ABSTRACT: Polyhydroxyalkanoates are linear polyesters that are produced by bacterial fermentation and are used as biodegradable bioplastics. β-Ketothiolase B (BktB) from Ralstonia eutropha (ReBktB) is a key enzyme for the production of various types of copolymers by catalyzing the condensation reactions of acetyl-CoA with propionyl-CoA and butyryl-CoA. The ReBktB protein was crystallized using the hanging-drop vapour-diffusion method in the presence of 25% polyethylene glycol 3350, 0.1 M bis-tris pH 6.5, 0.2 M lithium sulfate at 295 K. X-ray diffraction data were collected to a maximum resolution of 2.3 Å on a synchrotron beamline. The crystal belonged to space group C2221, with unit-cell parameters a = 106.95, b = 107.24, c = 144.14 Å. With two molecules per asymmetric unit, the crystal volume per unit protein weight (VM) is 2.54 Å(3) Da(-1), which corresponds to a solvent content of approximately 51.5%. The structure was solved by the molecular-replacement method and refinement of the structure is in progress.

    ABSTRACT: The hPrp19-CDC5L complex plays a crucial role during human pre-mRNA splicing by catalytic activation of the spliceosome. In order to elucidate the molecular architecture of the hPrp19-CDC5L complex, the crystal structure of CTNNBL1, one of the major components of this complex, was determined. Unlike canonical ARM-repeat proteins such as β-catenin and importin-α, CTNNBL1 was found to contain a twisted and extended ARM-repeat structure at the C-terminal domain and, more importantly, the protein formed a stable dimer. A highly negatively charged patch formed in the N-terminal ARM-repeat domain of CTNNBL1 provides a binding site for CDC5L, a binding partner of the protein in the hPrp19-CDC5L complex, and these two proteins form a complex with a stoichiometry of 2:2. These findings not only present the crystal structure of a novel ARM-repeat protein, CTNNBL1, but also provide insights into the detailed molecular architecture of the hPrp19-CDC5L complex.

    ABSTRACT: In this study, a combination of sequential extraction and mineralogical investigation by X-ray diffraction and X-ray photoelectron spectroscopy was employed in order to evaluate arsenic solid-state speciation and bioaccessibility in soils highly contaminated with arsenic from mining and smelting. Combination of these techniques indicated that iron oxides and the weathering products of sulfide minerals played an important role in regulating the arsenic retention in the soils. Higher bioaccessibility of arsenic was observed in the following order; i) arsenic bound to amorphous iron oxides (smelter-2), ii) arsenic associated with crystalline iron oxides and arsenic sulfide phase (smelter-1), and iii) arsenic associated with the weathering products of arsenic sulfide minerals, such as scorodite, orpiment, jarosite, and pyrite (mine). Even though the bioaccessibility of arsenic was very low in the mine soil, its environmental impact could be significant due to its high arsenic concentration and mobility.

    ABSTRACT: In this study, we monitored the newly added Stockholm Convention persistent organic pollutants (POPs) HCHs, PeCBz, endosulfans, chlordecone, PBDEs, PBBs and PFCs in industrial, urban, and agricultural soils in South Korea, in order to evaluate their distributions and potential sources. These POPs were widely distributed throughout South Korea, and their concentrations and distributions were affected by land use, reflecting their sources. The overall concentrations of HCHs, PeCBz, endosulfans, PBDEs, and PFCs in soils were in the range of ND (non-detectable)-0.358ng/g (average±standard deviation: 0.060±0.080ng/g), ND-0.531ng/g (0.083±0.133ng/g), 0.058-8.42ng/g (2.19±2.43ng/g), 0.004-4.78ng/g (0.68±1.06ng/g), and ND-1.62ng/g (0.50±0.46ng/g), respectively. Agricultural soils showed the highest concentration of endosulfan, which was the most recently used pesticide monitored in this study. On the other hand, industrial soils contained the highest concentrations of PeCBz, PBDEs, and PFCs, which were mainly introduced to environment via the industrial activities.

    ABSTRACT: Worldwide obesity and related comorbidities are increasing, but identifying new therapeutic targets remains a challenge. A plethora of microarray studies in diet-induced obesity models has provided large datasets of obesity associated genes. In this review, we describe an approach to examine the underlying molecular network regulating obesity, and we discuss interactions between obesity candidate genes. We conducted network analysis on functional protein-protein interactions associated with 25 obesity candidate genes identified in a literature-driven approach based on published microarray studies of diet-induced obesity. The obesity candidate genes were closely associated with lipid metabolism and inflammation. Peroxisome proliferator activated receptor gamma (Pparg) appeared to be a core obesity gene, and obesity candidate genes were highly interconnected, suggesting a coordinately regulated molecular network in adipose tissue. In conclusion, the current network analysis approach may help elucidate the underlying molecular network regulating obesity and identify anti-obesity targets for therapeutic intervention.

    ABSTRACT: Chitin-degrading bacterial strains were screened and tested for their ability to degrade shrimp-shell waste (SSW). Among the potential strains, B. cereus EW5 exhibited the highest chitin-degrading ability compared with other strains and produced 24 mg of reducing sugar per gram of dry SSW after 4 days of incubation. A TLC analysis of SSW biodegradation revealed that the chitosaccharides produced in the culture supernatant were mainly N-acetylglucosamine (GlcNAc) and chitobiose due to the isolate's exolytic chitinase activity. The culture supernatant exhibited a high degree of antioxidant activity, as indicated by 83% DPPH, 99.6% ABTS, 51% hydroxyl radical scavenging activity and 0.34 reducing power. The formation of GlcNAc and chitobiose during biodegradation of SSW is considered to be the major contributor to the antioxidant activity. The EW5 culture supernatant also displayed inhibition of DNA damage, enhancing the reutilization value of SSW. This report presents the first description of fermented production of GlcNAc and DNA protective activity of culture supernatant from SSW by B. cereus.

    ABSTRACT: To assess the effects of a visiting nurse-driven community-based case management program for low-income adults with hypertension. This single group pretest-post-test study included 22 newly registered low-income adult patients with hypertension in a public health center in Seoul. Visiting nurses delivered a case management program for 2-8 months. Pretest and post-test measurements of blood pressure (BP), knowledge level, and self-management level in terms of diet, lifestyle, physical activity, and medication were obtained. The visiting nurse-driven case management was effective in reducing the BP level and improving the knowledge and self-management level of the low-income adults with hypertension in the community. This study serves as a baseline for visiting nurse-driven case management for low-income patients with hypertension. Its findings suggest that visiting nurse-driven case management targeting the self management of BP can foster improved BP control for newly diagnosed hypertensive patients in low-income populations.

    ABSTRACT: Homosalate (HMS) is an ultraviolet (UV) filtering agent used in sunscreens and other cosmetics for skin protection purposes. Despite the widespread use of these products, absorption, disposition, and in vivo endocrine disrupting potential of HMS have not been characterized. Thus, the aim of this study was to examine the percutaneous absorption, disposition, and exposure assessment of HMS in rats. Initially, sunscreen preparations of petrolatum jelly, oily solution, lotion, and gel were prepared and evaluated for in vitro permeation of HMS across excised rat skin. Dermal permeability was greatest for gel, and this preparation was used in subsequent in vivo topical application investigations. After iv injection (0.5, 2, or 5 mg/kg), the pharmacokinetics of HMS was linear and was characterized by a large Vd ss (13.2-17 L/kg), high Cls (4.5-6.1 L/h/kg), and long t1/2 (6.1-8.4 h). After topical application of gel, the bioavailability of HMS was 5.4 ± 1.1 and 4.2 ± 0.6% for high and low doses (10 and 20 mg), respectively. Consistent with the prolonged absorption (T max 11.2 ± 1.8 and 12 ± 0 h for low and high doses, respectively), the terminal t 1/2 was longer after topical application (23.6-26.1 h) compared to iv injection. A population pharmacokinetic model was further developed to simultaneously fit the time courses of plasma concentrations and dermal content data after iv injection and topical application. Findings of this study may be useful to further examine the relationship between exposure and endocrine disrupting potential of HMS in risk assessment.

    ABSTRACT: The desire for a biocompatible and biodegradable material as a substitute for polydimethylsiloxane (PDMS), which is widely used for biomedical microfabrication, motivates an examination of alternate biomaterials: cellulose acetate (CA), poly lactic-co-glycolic acid (PLGA), and poly octanediol citrate (POC). Human bone marrow derived connective tissue progenitor cells (CTPs) were cultured on the biodegradable material surface microtextures comprised of both post microtextures and smooth surfaces for up to 30 days to compare growth characteristics. All biodegradable materials retained >95% of their original mass for 3 weeks. At week 10, the mass of PLGA was reduced by ∼18%, whereas the mass of CA and POC post microtextures were reduced by ∼13% and the mass of CA and POC smooth surfaces were reduced ∼10%. CTPs on CA and PLGA smooth surfaces exhibited arbitrary flattened shapes, while cells on CA microtextures mostly tended to attach next to the posts and spread between them. CTPs on CA and PLGA microtextured scaffolds displayed enhanced proliferation compared to those on PDMS surfaces. More specifically, CA (300%) exhibited higher cell proliferation compared to PLGA (190%) and PDMS (100%) on day 30. CTPs on CA microtextured scaffolds displayed comparable osteogenic differentiation to those on PDMS.

    ABSTRACT: The aim of this study was to develop a highly reliable radiofluorination method for the preparation of N-{2-[4-(2-methoxyphenyl)piperazinyl]ethyl}-N-(2-pyridyl)-N-(4-(18) F-fluoromethylcyclohexane)carboxamide ([(18) F]Mefway) by using a fully automated system. The optimal condition is composed of two parts. The extraction system of the trapped F-18 in the anion exchange resin (i.e., quaternary methylamine cartridge) is a complex of Kryptofix 2.2.2. (K222, 4 mg/0.9 mL methanol) and K2 CO3 (1 mg/0.1 mL H2 O). After removing the solvents, the trans-tosylated Mefway precursor (1 mg/0.5 mL acetonitrile) was reacted with dried K222-K[(18) F] at 100°C for 5 min. After purification and formulation, [(18) F]Mefway was obtained with 38 ± 2.4% (decay corrected, n = 34) radiochemical yield, a total synthesis time of 52 ± 3.4 min, specific activity was 120.6 ± 8.7 GBq/µmol at the end of synthesis and a radiochemical purity of 99%. According to the quality control tests, formulated [(18) F]Mefway is suitable to apply parenteral clinical application.

    ABSTRACT: There is a growing demand for the efficient treatment of seaweed waste. We identified six bacterial strains from the marine environment for the reutilization of brown-seaweed waste, and the most potentially useful strain, Microbacterium oxydans, was chosen and further investigated. Plate assays indicated that this bacterial isolate possessed both alginate lyase and laminarinase activities. The optimal inoculum size, pH, temperature and substrate concentration for the degradation of brown-seaweed polysaccharides by the isolate were as follows: 20% (v v(-1)), pH 6.0, 37 °C, and 5 g L(-1) for alginate and 20% (v v(-1)), pH 6.0, 30 °C, and 10 g L(-1) for laminarin, respectively. During 6 d in culture under the optimal conditions, the isolate produced 0.17 g L(-1) of reducing sugars from alginate with 11.0 U mL(-1) of maximal alginate lyase activity, and 5.11 and 2.88 g L(-1) of reducing sugars and glucose from laminarin, respectively. In particular, a fair amount of laminarin was degraded to glucose (28.8%) due to the isolate's exolytic laminarinase activity. As a result, the reutilization of brown-seaweed waste by this isolate appears to be possible for the production of reducing sugars as a valuable resource. This is the first study to directly demonstrate the ability of M. oxydans to degrade both alginate and laminarin.

    ABSTRACT: We aim to evaluate the association between promoter polymorphism of the clusters of differentiation 14 (CD14) gene and Helicobacter pylori-induced gastric mucosal inflammation in a healthy Korean population. The study population consisted of 267 healthy subjects who visited our hospital for free nationwide gastric cancer screening. Promoter polymorphism at -260 C/T of the CD14 gene was determined by polymerase chain reaction and restriction fragment length polymorphism analysis. The severity of gastric mucosal inflammation was estimated by a gastritis score based on the sum of the values of the grade and activity of the gastritis. Expression of soluble CD14 (sCD14) was assessed by quantitative sandwich ELISA. CD14 polymorphism was not associated with H. pylori infection. There were no significant differences in gastritis scores among the genotype subgroups, but subjects carrying the CD14 -260 CT/TT genotype had significantly higher sCD14 levels than those carrying the CC genotype. Subjects with the 260-T allele of the CD14 gene and H. pylori infection had significantly higher sCD14 levels than those with the same genotype but without infection. In individuals with the T allele at the -260 site of the promoter region of the CD14 gene, H. pylori infection accentuates gastric mucosal inflammation.

    ABSTRACT: BACKGROUND: The development of critical thinking dispositions has become an important issue in nursing education in Korea. Nursing colleges in Korea have developed teaching strategies and curricula that focus on developing critical thinking dispositions. It is an imperative step that evaluates the changing pattern and development of students' critical thinking dispositions. OBJECTIVES: This study identified critical thinking dispositions of Korean nursing students according to academic level and satisfaction with nursing. METHODS: A cross-sectional questionnaire survey was conducted among 1074 students in four colleges who completed the self-reported Critical Thinking Disposition Scale. Descriptive and univariate general linear model analyses were performed. RESULTS: The critical thinking disposition score increased according to academic level until junior year, after which it decreased in the senior year. Nursing students who were satisfied with nursing reported higher levels of critical thinking than those who were not satisfied or who responded neutrally. CONCLUSIONS: The critical thinking scores of nursing students not satisfied with nursing dropped greatly in the senior year. These results suggest the importance of targeting the development of curriculum and teaching methods for seniors and students who have a lower level of satisfaction with nursing to increase their critical thinking dispositions.

    ABSTRACT: Varying geometry and layout of microposts on a cell culture substrate provides an effective technique for applying mechanical stimuli to living cells. In the current study, the optimal geometry and arrangement of microposts on the polydimethylsiloxane (PDMS) surfaces to enhance cell growth behavior were investigated. Human bone marrow derived connective tissue progenitor cells were cultured on PDMS substrates comprising unpatterned smooth surfaces and cylindrical post microtextures that were 10 μm in diameter, 4 heights (5, 10, 20 and 40 μm) and 3 pitches (10, 20, and 40 μm). With the same 10 μm diameter, post heights ranging from 5 to 40 μm resulted in a more than 535 fold range of rigidity from 0.011 nNμm(-1) (40 μm height) up to 5.888 nNμm(-1)(5 μm height). Even though shorter microposts result in higher effective stiffness, decreasing post heights below the optimal value, 5 μm height micropost in this study decreased cell growth behavior. The maximum number of cells was observed on the post microtextures with 20 μm height and 10 μm inter-space, which exhibited a 675 % increase relative to the smooth surfaces. The cells on all heights of post microtextures with 10 μm and 20 μm inter-spaces exhibited highly contoured morphology. Elucidating the cellular response to various external geometry cues enables us to better predict and control cellular behavior. In addition, knowledge of cell response to surface stimuli could lead to the incorporation of specific size post microtextures into surfaces of implants to achieve surface-textured scaffold materials for tissue engineering applications.

    ABSTRACT: Background and Aims: Peritoneal dialysis (PD) is characterized by a gain in fat mass. Unlike subcutaneous fat, visceral fat is associated with metabolic syndrome and survival. We prospectively examined whether visceral or subcutaneous fat could predict outcome in patients undergoing PD. METHODS: We studied 117 new patients (57 men) undergoing PD between February 2006 and November 2011. Baseline body composition was measured on computed tomograms. Visceral obesity was defined as a visceral fat area exceeding 100 cm2, and subcutaneous obesity, as a subcutaneous fat area exceeding 130 cm2. RESULTS: Among the 117 patients, 37 and 29 were diagnosed with visceral and subcutaneous obesity respectively. Visceral and subcutaneous obesity were both present in 21 patients. In the study population, the 1-year and 5-year survival rates were 94% and 59%. The rates of peritonitis and exit-infection were 0.31 and 0.14 episodes per patient-year. Mortality was greater in patients with visceral obesity than in those without visceral obesity (p = 0.005). Visceral obesity had no influence on peritonitis and exit-infection rates. Subcutaneous obesity was associated neither with survival nor with peritonitis or exit-site infection. In a multivariate Cox regression analysis, visceral obesity was not a risk factor for poor outcome. CONCLUSIONS: Increased visceral fat at PD initiation is not an independent predictor of poor survival. Any impact of visceral or subcutaneous fat mass on outcomes in patients undergoing PD would be better defined by larger, long-term studies.

    ABSTRACT: The purpose of this study was to evaluate measurement properties of self-report questionnaires for studies published in Korean nursing journals. Of 424 Korean nursing articles initially identified, 168 articles met the inclusion criteria. The methodological quality of the measurements used in the studies and interpretability were assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. It consists of items on internal consistency, reliability, measurement error, content validity, construct validity including structural validity, hypothesis testing, cross-cultural validity, and criterion validity, and responsiveness. For each item of the COSMIN checklist, measurement properties are rated on a four-point scale: excellent, good, fair, and poor. Each measurement property is scored with worst score counts. All articles used the classical test theory for measurement properties. Internal consistency (72.6%), construct validity (56.5%), and content validity (38.2%) were most frequently reported properties being rated as 'excellent' by COSMIN checklist, whereas other measurement properties were rarely reported. A systematic review of measurement properties including interpretability of most instruments warrants further research and nursing-focused checklists assessing measurement properties should be developed to facilitate intervention outcomes across Korean studies.

    ABSTRACT: Attention deficit hyperactivity disorder (ADHD) is a common disorder of the school age population. ADHD has been shown to be familial, and genetic studies estimate its heritability at 80%-90%. The aim of the present study was to investigate the association between the genetic type and alleles for the HTR1A gene in Korean children with ADHD. The sample consisted of 142 ADHD children and 139 control children. We diagnosed ADHD according to Diagnostic and Statistical Manual of Mental Disorders-4th edition. ADHD symptoms were evaluated with Conners' Parent Rating Scales and Dupaul Parent ADHD Rating Scales. Blood samples were taken from the 281 subjects, DNA was extracted from blood lymphocytes, and polymerase chain reaction was performed for HTR1A polymorphism. Alleles and genotype frequencies were compared using the Chi-square test. We compared the allele and genotype frequencies of HTR1A gene polymorphism in the ADHD and control groups. This study showed that there was a significant correlation among the frequencies of the rs10042486 (OR=1.55, 95% CI=1.02-2.30, p=0.041), rs1423691(OR=1.55, 95% CI=1.02-2.30, p=0.041),and rs878567(OR=1.60, 95% CI=1.06-2.43, p=0.027) alleles of HTR1A, but the final conclusions are not definite. Follow-up studies with larger patient or pure subgroups are expected. These results suggested that HTR1A might be related to ADHD symptoms.

    ABSTRACT: Gold nanoparticles (AuNPs) stabilized with sodium alginate (SA), glycol chitosan (GC), polyvinyl alcohol (PVA), and polyethyleneimine (PEI) were synthesized in aqueous solutions at room temperature. Different sizes and size distributions of AuNPs were obtained according to the polymeric stabilizers. The mean particle diameters of AuNPs synthesized with GC and PVA as stabilizers were about 5.1 and 5.3 nm, respectively, while those of AuNPs stabilized with SA and PEI were 8.4 and 10.8 nm, respectively. When SA was used, relatively large particles aggregated to form large clusters. In the case of GC, a number of small particles built up large clusters. When PVA was used, the size and the number of nanoparticles were estimated small with a low weight content of Au. For this reason, the PVA-stabilized AuNPs formed clusters with a small hydrodynamic size. The AuNPs synthesized in the aqueous solution of PEI without a reducing agent, sodium borohydride, were uniform in size and formed the smallest nanoclusters (67.4 nm). In this case, the highest Au content was obtained. Sufficiently grown nanoparticles with a high Au content and a limited hydrodynamic size are considered to be suitable for a variety of applications.
