Bacterial biofilms formed on equipment surfaces are potential sources of cross-contamination and can be responsible for the spread of bacteria involved in food spoilage, such as some Enterobacteriaceae family members. In this study, the effect of chlorite-based disinfectants, including sodium hypochlorite (SH), chlorine dioxide (CD), strongly acidic electrolyzed water (StAEW), and neutral electrolyzed water (NEW), on inactivation of mono-biofilms of Enterobacter cloacae, Klebsiella oxytoca, and Citrobacter freundii was evaluated separately...

Fixed-beam radiotherapy systems with subjects rotating about a longitudinal (horizontal) axis are subject to gravity-induced motion. Limited reports on the degree of this motion, and any deformation, has been reported previously. The purpose of this study is to quantify the degree of anatomical motion caused by rotating a subject around a longitudinal axis, using cone-beam CT (CBCT). 
 
 In the current study, a purpose-made longitudinal rotating was aligned to a Varian TrueBeam kV imaging system...

Chronic kidney disease (CKD) is a frequent complication of type 2 diabetes mellitus (T2DM) and elevates individuals' risk for cardiovascular disease, the leading cause of morbidity and mortality in T2DM. Achieving and maintaining tight glycemic control is key to preventing development or progression of CKD; however, improving glycemic control may be limited by effects of renal impairment on the efficacy and safety of T2DM treatments, necessitating dosing adjustments and careful evaluation of contraindications...

BACKGROUND: An epidemic of chronic kidney disease (CKD) has been observed in Central America among workers in the sugarcane fields. One hypothesis is that the CKD may be caused by recurrent heat stress and dehydration, and potentially by hyperuricemia. Accordingly, we developed a murine model of kidney injury associated with recurrent heat stress. In the current experiment, we tested whether treatment with allopurinol (a xanthine oxidase inhibitor that reduces serum urate) provides renal protection against recurrent heat stress and dehydration...

Urine erythrocyte (Ery) and leukocyte (Leu) dipstick tests are essential for detecting microhematuria and urinary tract infection. Currently, there is no suggestion for establishing the cut-off limits in an ordinal scale test. This study aimed to establish the cut-off limits for urine Ery and Leu dipstick tests via probit regression. From 1 January 2016 to 30 June 2016, laboratory data were collected from patients at one teaching hospital whose specimen had analytical results from both a urine dipstick test and an automated urine particle analyzer...

OBJECTIVE: Motion artifact can reduce the diagnostic accuracy of coronary CT angiography (CCTA) for coronary artery disease (CAD). The purpose of this study was to compare the diagnostic performance of an algorithm dedicated to correcting coronary motion artifact with the performance of standard reconstruction methods in a prospective international multicenter study. SUBJECTS AND METHODS: Patients referred for clinically indicated invasive coronary angiography (ICA) for suspected CAD prospectively underwent an investigational CCTA examination free from heart rate-lowering medications before they underwent ICA...

OBJECTIVE: This study examines whether, in panic-focused psychodynamic psychotherapy (PFPP), interpretations of conflicts that underlie anxiety (panic-focused or PF-interpretations) are specifically associated with subsequent panic disorder (PD) symptom improvement, over and above the provision of non-symptom-focused interpretations. METHOD: Technique use in Sessions 2 and 10 of a 24-session PFPP protocol was assessed for the 65 patients with complete outcome data randomized to PFPP in a two-site trial of psychotherapies for PD...

Supercritical fluid extraction (SFE) was applied to investigate the removal of petroleum hydrocarbons (PHCs) from contaminated soils. Per an initial set of tests for different extraction modes and time durations, the combination of 10 min static mode followed by 10 min dynamic mode, repeated for 3 cycles for a total time of 60 min resulted in the highest PHCs removal percentages. SFE experiments were performed at 33 MPa pressure and 75 °C temperature to investigate the influence of soil texture and grain size...

Background Although transarterial embolization (TAE) can powerfully control postpartum hemorrhage (PPH), clinical failure of TAE is not uncommon. Purpose To discover whether any parameters could predict timely clinical failure of TAE, then whether a supplementary intervention could be promptly initiated. Material and Methods We retrospectively analyzed 118 TAE procedures in 113 patients with PPH performed at our institution between January 2012 and May 2015. The patients were divided into the following groups: clinically successful TAE and failed TAE...

The objective of the present study was to elucidate the distribution of 2-(dimethylamino)ethyl-(1-hydroxycyclopentyl)(phenyl)acetate in the organism of the warm-blooded animals after its intra-gastric administration. The methods applied in the study included thin layer chromatography in silicagel, aci-nitroprosalt staining reaction, UV-spectrophotometry,, and GC-mass spectrometry. The identification and the quantitation of 2-(dimethylamino)ethyl-(1-hydroxycyclopentyl)(phenyl)acetate in the organs and blood of the warm-blooded animals were carried out within 20, 150, and 360 min after a single intra-gastric administration of 1300 ml of this poisonous substance...

Industrial waste such as metal hydroxide sludge (in natura and calcined) from galvanic bath was evaluated as an adsorbent in the removal of brilliant blue synthetic dye (NB 180) in aqueous solution. The samples were characterised using X-ray fluorescence analysis (XRF), X-ray diffraction analysis (XRD), thermogravimetric analysis (TGA), infrared spectroscopy (FT - IR), as well as the specific surface area (BET) and the point of zero charge (pHZCP ). The effects of the conditions in relation to pH and adsorbent dosage were also investigated...

In this study, the feasibility of preparing activated carbon from waste tea by physical activation using steam was investigated. The effects of activation temperature on yield and pore properties of the prepared activated carbon were studied. The yield decreased with increased activation temperature owing to the decomposition of cellulose and hemicellulose. The specific surface area and pore volume of the activated carbon were estimated using the Brunauer-Emmett-Teller method, Langmuir equation, and t-plot method...

PURPOSE: To investigate the effects of ionising radiation on telomere length and telomerase activity in Human Lens Epithelial cells. There are studies suggesting evidence of telomere length in association with opacity of the lens, however, these studies have been conducted on Canine Lens cells. Our study was designed to understand further the effects of different doses of ionising radiation on telomere length and telomerase activity in cultured Human Lens Epithelium cells from three Donors...

To improve the physical and chemical properties of phenazine-1-carboxylic acid (PCA) and find higher antifungal compounds, a series of PCA amide analogues were designed and synthesized and their structures were confirmed by 1 H NMR, HRMS, and X-ray. Most compounds showed some antifungal activities in vitro. Particularly, compound 3d exhibited inhibition effect against Pyriculariaoryzac Cavgra with EC50 value of 28.7 μM and compound 3q exhibited effect against Rhizoctonia solani with EC50 value of 24.5 μM, more potently active than that of the positive control PCA with its EC50 values of 37...

To understand the instability of Sn-based perovskite, CH3 NH3 SnI3 , photoelectron spectroscopy with the synchrotron radiation and theoretical calculations such as density functional theory and ab-initio molecular dynamics were performed. From these experimental and theoretical works, we found the crucial changes of surface-chemical states, the broken chemical bondings in Sn-I, and the depletion of a CH3 -NH3 molecule in the surface region. The material instability origin of Sn-based perovskite can be explained by the chemical state instability in the surface...

New applications of DNA and RNA sequencing are expanding the field of biodiversity discovery and ecological monitoring, yet questions remain regarding precision and efficiency. Due to primer bias, the ability of metabarcoding to accurately depict biomass of different taxa from bulk communities remains unclear, while PCR-free whole mitochondrial genome (mitogenome) sequencing may provide a more reliable alternative. Here we used a set of documented mock communities comprising 13 species of freshwater macroinvertebrates of estimated individual biomass, to compare the detection efficiency of COI metabarcoding (3 different amplicons) and shotgun mitogenome sequencing...
