Ja Young Lee, Young Ok Kim
The radiocephalic arteriovenous fistula (AVF) provides optimal vascular access for hemodialysis; it has a higher long-term patency rate and fewer complications than other vascular access methods. However, the AVF has a high primary failure rate. The presence of small-diameter vessels at anastomosis sites is an important risk factor for AVF failure. However, in a recent study, despite selecting an adequate artery and vein for creating an AVF by routine preoperative vascular mapping, AVF maturation and primary failure occurred...

Rapid immunohistochemistry (R-IHC) has been developing mainly as a support technique in the rapid diagnosis of central nervous system tumors; however, there have been problems regarding instability in specimen preparation and immunostaining. To overcome the weakness of this technology, the instability of immunostaining, we developed a modified R-IHC. This was achieved by switching to 4% paraformaldehyde as the fixative solution and utilizing a commercially available Polymer Refine Detection Kit, as a high-sensitivity kit, in place of the secondary antibodies...

Herein, we have studied the photophysical properties for three newly synthesized coumarin derivatives; 4-((2,6-dibromo-4-methylphenoxy)methyl)-2H-benzo[h]chromen-2-one (DMB), 4-((3,4-dihydro-6,7-dimethoxyisoquinolin-1-yl)methyl)-6-methyl-2H-chromen-2-one (DIM) and 4-((p-tolyloxy)methyl)-6-methoxy-2H-chromen-2-one (TMC). The absorption and emission spectra for above said molecules were recorded in different solvents at room temperature in order to calculate their ground and excited state dipole moments. The ground (μ g ) and excited state dipole (μ e ) moments of these coumarin derivatives were calculated using Lippert's, Bakshiev's and Kawski-Chamma-Viallet's equations by the solvatochromic shift method, which involves a variation of Stokes shift with the solvent dielectric constant and refractive index...

Wound dressings play important roles in the management of wounds, and calcium cross-linked alginate (Ca(2+)-Alg) is a commonly used hydrogel that is adapted for wound treatment. However, conventional methods for fabricating Ca(2+)-Alg hydrogels can be tedious and difficult to control because of the rapid Ca(2+)-induced gelation of alginate. In this study, An electrodeposition method was used to rapidly and controllably fabricate Ca(2+)-Alg films for wound treatment. Several measures of film growth (e.g., thickness and mass) are shown to linearly correlate to the imposed charge transfer at the electrode...

Background Digoxin is a cardiac glycoside that is recommended by clinical practice guidelines to be used in patients with heart failure with reduced ejection fraction (HFrEF) who still have persistent symptoms despite optimal medical therapy. However, this recommendation is based on limited and old trial data. Moreover, pharmacoepidemiologic studies are important in determining the prevalence of digoxin use and factors influencing this. Objective This study aimed to determine the prevalence and the predictors of digoxin utilization among patients with HFrEF with or without atrial fibrillation (AF) in Qatar...

One of the treatments to infertility is In Vitro Fertilization (IVF). In the course of IVF, fertilization rate can be improved through stress reduction. Probably one of the causes of low outcome of IVF is changes in uterine glycoconjugates that are first site of contact between blastocyst and uterus, due to stress, e.g., stress of injection. Thus, the study of the injectional stress effects on implantation period is very important to improve the outcome of IVF. Sixteen mature female rats were divided to experimental and control groups...

María A Rossin, Pablo N De Francesco, Juan T Timi
Dactylogyridae is overwhelmingly the most abundant and diverse taxon among monogeneans in continental waters of South America. Their small body size requires considerable sampling effort and training for collecting and identifying the worms from the gills, skin, nasal cavities, and other microhabitats. Indeed, diagnostic characteristics as sclerites and male copulatory complex are generally less than 100-μm long and are essential for taxonomic description and identification of species. Here, a combination of simple and routine methods for three-dimensional morphological studies on hard structures is proposed for dactylogirids: SDS treatment for clarification of specimens and enzymatic digestion with proteinase K for freeing sclerotized structures, followed by laser confocal microscopy...

The widespread use of molecular PCR-based assays in analytical and clinical laboratories brings about the need for test-specific, stable, and reliable external controls (EC) as well as standards and internal amplification controls (IC), in order to arrive at consistent test results. In addition, there is also a growing need to produce and provide stable, well-characterized molecular controls for quality assurance programs. In this study, we describe a novel approach to generate armored double-stranded DNA controls, which are encapsulated in baculovirus (BV) particles of the species Autographa californica multiple nucleopolyhedrovirus...

In Iran, patients showing rifampicin (RIF) resistance detected by the Xpert® MTB/RIF assay are considered as candidates for multidrug-resistant tuberculosis (MDR-TB) treatment. Despite the fact that RIF resistance has been used as a proxy for MDR-TB, little is known about the proportion of isoniazid (INH) resistance patterns in RIF-resistant TB. We systematically searched MEDLINE, Embase, and other databases up to March 2017 for studies addressing the proportion of INH resistance patterns in RIF-resistant TB in Iran...

Importance: Patients with cancer who use statins appear to have a substantially better survival than nonusers in observational studies. However, this inverse association between statin use and mortality may be due to selection bias and immortal-time bias. Objective: To emulate a randomized trial of statin therapy initiation that is free of selection bias and immortal-time bias. Design, Setting, and Participants: We used observational data on 17 372 patients with cancer from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database (2007-2009) with complete follow-up until 2011...

The aim of this analytical study was to develop and validate an easy-to-use method for measuring the actual level of norflurazon that accumulates in leaves. We amended the QuEChERS method, i.e. Quick, Easy, Cheap, Effective, Rugged, and Safe, which is widely used for pesticide and herbicide analysis in food, and usually combined with HPLC-MS detection. We adapted this method for the detection of norflurazon in leaves or leaf fragments and proposed a useful modification using of HPLC-UV detection. Reproducible retention times of 3...

BACKGROUND It is important to avoid relapse in autoimmune hepatitis (AIH) because repeated multiple relapses have been associated with a worse prognosis. However, risk factors for relapse before initiation of treatment are not fully understood. The aim of this study was to find predictive markers for relapse of type 1 AIH. MATERIAL AND METHODS We reviewed the records of 53 patients diagnosed with type 1 AIH based on the revised scoring system proposed by the International Autoimmune Hepatitis Group (IAIHG) between 2009 and 2014 at 4 hospitals belonging to the Saga Study Group of Liver Diseases (SASLD)...

Principal component analysis (PCA) is frequently adopted for creating socioeconomic proxies in order to investigate the independent effects of wealth on disease status. The guidelines and methods for the creation of these proxies are well described and validated. The Demographic and Health Survey, World Health Survey and the Living Standards Measurement Survey are examples of large data sets that use PCA to create wealth indices particularly in low and middle-income countries (LMIC), where quantifying wealth-disease associations is problematic due to the unavailability of reliable income and expenditure data...

AIMS: Reports into standards in the National Health Service and quality in pathology have focused on the way we work in pathology and how to provide assurance that this is of a high standard. There are a number of external quality assurance schemes covering pathology and histopathology specifically; however, there is no scheme covering the process of histological surgical dissection. This is an area undergoing development, emerging from the sole preserve of medically qualified pathologists to a field populated by a number of highly trained biomedical scientists, but remains without any formal quality assurance...

In the present study, the deflocculated sludge was disintegrated through thin layer immobilized titanium dioxide (TiO2) as photocatalyst under solar irradiation. The deflocculation of sludge was carried out by 0.05g/g SS of sodium citrate aiming to facilitate more surface area for subsequent TiO2 mediated disintegration. The proposed mode of disintegration was investigated by varying TiO2 dosage, pH and time. The maximum COD solubilization of 18.4% was obtained in the optimum 0.4g/L of TiO2 dosage with 5.5 pH and exposure time of 40min...

Exhaled breath condensate (EBC) is easily obtained for clinical diagnosis and prognosis for pulmonary diseases and has gained much interest in biomarker discovery research and studies. Lactate, a physiological material, is found in EBC and has been demonstrated to be a potential indicator of chronic obstructive pulmonary disease and other lung diseases. Several assays are available to detect lactate in human body fluids, and yet none is suitable for detecting lactate in EBC. Due to the very low concentration of lactate in EBC and low volume of EBC, it is very important to develop an assay to measure lactate with high sensitivity, accuracy and easy sample processing...

A better understanding of the dominant source areas and transport pathways of pesticide losses to surface water is needed for targeting mitigation efforts in a more cost-effective way. To this end, we monitored pesticides in surface water in an agricultural catchment typical of one of the main crop production regions in Sweden. Three small sub-catchments (88-242ha) were selected for water sampling based on a high-resolution digital soil map developed from proximal sensing methods and soil sampling; one sub-catchment had a high proportion of clay soils, another was dominated by coarse sandy soils while the third comprised a mix of soil types...
