Seasonal variations in the concentrations of eight ultraviolet (UV) filters and 22 illicit drugs including their metabolites in the Korean aquatic environment were investigated. Seawater samples from three beaches, water samples from two rivers, and influents and effluents from three wastewater treatment plants were analyzed. The UV filter concentrations in the seawater, river water, and effluent samples were 39.4-296, 35.4-117, and 6.84-51.1 ng L(-1), respectively. The total UV filter concentrations in the seawater samples were 1...

Oxybenzone (OBZ), a common ingredient in sunscreens and personal care products, has been frequently detected in effluents from municipal wastewater treatment plants and also in surface waters. OBZ is an emerging contaminant due to its adverse impacts on marine/aquatic ecosystems. To investigate the removal and degradation capacity of phytotreatment for OBZ, the common wetland plant species Cyperus alternifolius L. was exposed to this compound at 5, 25 and 50 μM for 120 h, respectively. Continuous uptake by roots and accumulation in plant tissues was observed over the exposure time, and depletion of spiked OBZ from the aqueous medium exceeded 73...

Surface plasmon resonance (SPR) biosensors are most commonly applied for real-time dynamic analysis and measurement of interactions in bio-molecular studies and cell-surface analysis without the need for labeling processes. Up to present, SPR application in stem cell biology and biomedical sciences was underused. Herein, a very simple and sensitive method was developed to evaluate human mesenchymal stem cells trans-differentiation to endothelial lineage of over a period of 14 days based on VE-cadherin biomarker...

Common methods of managing dairy manure are directly applying it to the farm field as a fertilizer. For direct application without any type of treatment, the majority of nutrients in the manure run off to the local river and lake during precipitation periods. The algae bloom is one of the environmental outcomes due to eutrophication of the lakes, which may jeopardize the quality of drinking water. In this study, superheated steam drying (SSD) technology is investigated as an alternative manure management method...

Our objectives were to (Exp. 1) determine the effect of postmortem aging (2, 3, 4, 14, 28, and 42days) on calpain-1 and -2 activity in beef longissimus lumborum (LL) and semimembranosus (SM) steaks and (Exp. 2) determine the effect of postmortem aging for two extended periods (63 and 84days) on calpain-2 activity of beef SM steaks. Calpain-1 was not active in either muscle following 14days of aging. Native calpain-2 activity decreased (P<0.001) with longer aging periods for both the LL and SM in Exp. 1 and for the SM in Exp...

A three-layer system of nanocrystalline hydroxyapatite (first layer; 1000nm thick), silver nanoparticles (second layer; 1.5μg Ag cm(-2)) and calcium phosphate (third layer, either 150 or 1000nm thick) on titanium was prepared by a combination of electrophoretic deposition of silver nanoparticles and the deposition of calcium phosphate by radio frequency magnetron sputtering. Scanning electron microscopy showed that the silver nanoparticles were evenly distributed over the surface. The adhesion of multilayered coating on the substrate was evaluated using the scratch test method...

Reactive oxygen species, which increase under various environmental stresses, have deleterious effects on plants. An important antioxidant, glutathione, is used to detoxify reactive oxygen species in plant cells and is mainly produced by two enzymes: gamma-glutamylcysteine synthetase (γ-ECS) and glutathione synthetase (GS). To evaluate the functional roles of the glutathione synthetase gene (OsGS) in rice, we generated four independent transgenic rice plants (TG1-TG4) that overexpressed OsGS under the control of the constitutively expressed OsCc1 promoter...

A Single Particle Aerosol Mass Spectrometer (SPAMS) was deployed in the urban area of Chongqing to characterize the particles present during a severe particulate pollution event that occurred in winter 2014-2015. The measurements were made at a time when residents engaged in traditional outdoor meat smoking activities to preserve meat before the Chinese Spring Festival. The measurement period was predominantly characterized by stagnant weather conditions, highly elevated levels of PM2.5, and low visibility...

A significant part of the optical metamaterial phenomena has the plasmonic nature and their investigation requires very accurate knowledge of the fabricated structures shape with a focus on the periodical features. We describe a consistent approach to the shape reconstruction of the plasmonic nanostructures. This includes vertical and tilted spike AFM probes fabrication, AFM imaging and specific post-processing. We studied a complex-shaped chiral metamaterial and conclude that the described post-processing routine extends possibilities of the existing deconvolution algorithms in the case of periodical structures with known rotational symmetry, by providing valuable information about periodical features...

BACKGROUND: fetal Alcohol Spectrum Disorders is a term used to describe a range of physical, cognitive and behavioural deficits in the offspring of women who drank alcohol during pregnancy. A growing body of evidence suggests alcohol consumption in the presence of poor maternal nutrition may increase the risk of harm to the developing fetus. OBJECTIVE: to investigate relationships between maternal dietary patterns and alcohol consumption, and explore which factors influence women's decisions about what to eat and drink during pregnancy...

INTRODUCTION: Clostridium difficile infection is the leading cause of nosocomial infectious diarrhea. The increasing incidence added to a lower rate of response to the initial treatment and higher rates of relapse has generated a higher burden of the disease. OBJECTIVE: To determine the clinical characteristics of hospitalized patients with C. difficile infection. MATERIALS AND METHODS: We made a nested case-cohort study. We reviewed medical records of the patients with nosocomial diarrhea for whom an assay for toxin A-B of C...

Bone morphogenetic protein 9 (BMP9) has previously been characterized as the strongest osteoinductive growth factor among the BMP family. The aim of the present study was to evaluate the possibility of combining rhBMP9 with an injectable biphasic calcium phosphate (I-BCP, maxresorb inject®), since I-BCP is an easy to handle biomaterial with ideal properties for bone augmentation procedures. The adsorption potential of rhBMP9 as well as the cell behavior of bone stromal ST2 cells were investigated on cell viability, adhesion, proliferation and osteogenic differentiation for I-BCP combined with/without rhBMP9 in vitro...

BACKGROUND: M3 muscarinic receptor antagonism has been associated with glucose intolerance and disturbance of insulin secretion. OBJECTIVE: Our objective was to examine the risk of type 2 diabetes mellitus (T2DM) in patients using antidepressants with and without M3 muscarinic receptor antagonism (AD_antaM3 and AD_nonantaM3, respectively). METHODS: We designed a case-control study using a pharmacy prescription database. We selected a cohort of patients who initiated antidepressant use between the ages of 20 and 40 years and who did not receive any anti-diabetic prescriptions at baseline...

PURPOSE OF REVIEW: The purpose of this review is to provide an introduction to quality of life (QOL) outcomes after bariatric surgery and a summary of the current evidence. RECENT FINDINGS: QOL has been emphasized in bariatric surgery since the NIH Consensus Conference statement in 1991. Initial studies were limited to 1- and 2-year follow-up. More recent findings have expanded the follow-up period up to 12 years, providing a better description of the impact on long-term QOL...
