Dictyocaulus arnfieldi is a lungworm commonly found in equids; however, relatively little is known about it. The aim of the present study was to establish the prevalence of equine lungworms in naturally-infected working and sporting horses, donkeys and mules in rural areas of Urmia, northwest Iran. The fecal samples were collected from 299 working horses, 57 sporting horses, 66 donkeys and 37 mules during the period March 2014 to June 2016. The collected fecal samples were processed within 48 hours following rectal sampling...

A novel pretreatment strategy based on combination of microwave and ionic liquid [TBA][OH] was developed for enhancing enzymatic hydrolysis of Eucalyptus sawdust. The sugar yield of pretreated sample achieved 410.67 mg/g in 48 h, which suffered from optimized microwave-assisted [TBA][OH] pretreatment. The work mechanism was illuminated by chemical composition, Fourier transform infrared spectroscopy (FTIR), 13 C cross polarization/magic-angle spinning solid state NMR (13 C solid NMR), X-ray diffraction (XRD) and scanning electron microscope (SEM) analyses...

Klotho is considered to have renal protective effect by prohibiting the activation of the nuclear factor (NF)-κB pathway, while the role of microRNA-199a (miR-199a)/Klotho in lupus nephritis (LN) is still unknown. A single dose of pristane (0.5 ml) was intraperitoneally injected into 8 weeks-old female mice to establish the LN model. MiR-199a mimic or miR-199a inhibitor, Klotho plasmid or Klotho siRNA, and miR-199a inhibitor plus si-Klotho were transfected into lipopolysaccharides (LPS) stimulated human embryonic kidney 293 T (HEK293 T) cells...

Chlorinated paraffins (CPs) are now attracting special concerns worldwide as one type of new persistent toxic substances as classified by the Stockholm Convention. CPs are extensively applied in household goods and indoor decoration materials, but information on their occurrence and exposure risk in such environments is still very scarce. In this study, the current concentrations, particle size distributions, and inhalation exposure characteristics and risk of CPs were investigated in regard to indoor air particulate matter...

The correct description of neutron transport in lead is an essential task for correct description of tritium production in the DEMO (DEMOnstration Power Station) breeding blanket because some concepts deal with lead as a major component: namely the WCLL (water cooled lithium lead blanket), HCLL (helium cooled lithium lead blanket), and DCLL (dual cooled lithium lead blanket). Concerning the improvement of the knowledge about the transport of fast neutrons in lead, a set of experiments and calculations was carried out to study this problem with a well-defined neutron beam...

X-ray diffraction (XRD) patterns and near-infrared (NIR) spectra have been evaluated and compared to differentiate hydrothermal kaolinite, dickite and kaolinite-dickite. The spectral bands were fitted for the first overtone and combination area of the infrared spectra of kaolinite, dickite and kaolinite-dickite, and the characteristic bands of kaolinite, dickite and kaolinite-dickite were obtained. The infrared spectra of kaolinite and dickite have obvious differences in the first overtone and combination area of OH bands...

Despite the active applications of thermal comfort indices for heat wave definitions, there is lack of evaluation for the impact of extended days of high temperature on health outcomes using many of the indices. This study compared the impact of heat waves on health outcomes among different heat wave definitions based on thermal comfort and air temperature. We compared heat waves in South Korea (cities and provinces) for the warm season for 2011-2014, using air temperature, heat index (HI), and web-bulb globe temperature (WBGT)...

This study examines co-located aerosol and precipitation chemistry data between 2010 and 2016 at Pinnacles National Monument ~65 km east of the coastline in central California. Positive matrix factorization analysis of the aerosol composition data revealed seven distinct pollutant sources: aged sea salt (25.7% of PM2.5 ), biomass burning (24.2% of PM2.5 ), fresh sea salt (15.0% of PM2.5 ), secondary sulfate (11.7% of PM2.5 ), dust (10.0% of PM2.5 ), vehicle emissions (8.2% of PM2.5 ), and secondary nitrate (5...

The role of hyaluronic acid (HA) in supporting low friction and low abrasion during movement in synovial joints is still not fully understood. In this study, we set out to investigate the interaction between HA and representative lipid model membranes, bilayers as well as monolayers, in detail using a variety of calorimetric, spectroscopic, scattering and microscopic techniques, to explore their role in lubrication of articular cartridge. We also cover a wide range of pressures to mimic pressures occurring upon joint movement, aiming at elucidating a possible mechanism for the low friction forces in synovial joints...

Parkinson's disease (PD) is the second most frequent neurodegenerative disorder. Impaired metabolism of alpha-synuclein (SNCA) and its aggregation are implicated in PD pathogenesis. SNCA has been identified as a highly significant genetic risk loci associated with the sporadic form of PD in across populations in GWAS and replicative studies. In this study we conducted a genetic analysis of five SNCA single nucleotide polymorphisms (SNPs) (rs356219, rs2619364, rs11931074, rs2583988, rs356168) in 458 PD patients and 353 from North-West region of Russia...

The brain consists of distinct domains defined by sharp borders. So far, the mechanisms of compartmentalization of developing tissues include cell adhesion, cell repulsion, and cortical tension. These mechanisms are tightly related to molecular machineries at the cell membrane. However, we and others demonstrated that Slit, a chemorepellent, is required to establish the borders in the fly brain. Here, we demonstrate that Netrin, a classic guidance molecule, is also involved in the compartmental subdivision in the fly brain...

Hepatic fibrosis is the result of wound healing and inflammation resulting in organ dysfunction. Hepatocytes, liver sinusoidal endothelial cells (LSECs), Kupffer cells (KCs), and hepatic stellate cells (HSCs) play critical roles in fibrogenesis. As the liver undergoes fibrosis, there are populations of cells that are healthy, fibrotic as well as those undergoing fibrosis. We investigated how a varying mechanical environment could induce changes in hepatic cells. In this study, a gradient in the mechanical properties of the microenvironment resulted in transitioning phenotypes in hepatic cells...

This work uncovers the implications of the estimation of exogenous inactivation rates for E. coli after the initial lag phase, and presents a strategy for the determination of the second-order inactivation rate constants (k2nd ) of these bacteria with relevant transient species promoted by solar light in natural waters. For this purpose, specific precursors were considered (nitrate ion, rose bengal, anthraquinone-2-sulfonate) as well as the respective photo-generated transient species (i.e., hydroxyl radical (•OH), singlet oxygen (1 O2 ) and triplet excited states)...

AIM: The implications of diagnosis and treatment of central or axial atlantoaxial dislocation (CAAD) as a cause of symptoms of cervical myelopathy is evaluated. MATERIAL AND METHODS: This is a report of a series of 5 patients who presented with the primary symptoms of spasticity and motor weakness and paresthesiae in all the limbs. There was no evidence of any significant compression of the dural tube or neural structures at the craniovertebral junction. There was no craniovertebral junction instability when assessed by classically described radiological parameters...

BACKGROUND: The retroclival region is among the rarest locations for an arachnoid cyst (AC), with only a few published case reports. There is no accepted classification system for these rare cysts. Such a classification system will solve the nomenclature problem and may result in an easier and more systematic management. In this article, databases and literature on retroclival ACs (RACs) are reviewed and analyzed and a classification system is proposed. METHODS: A retrospective review for RACs was conducted in Marmara and Adiyaman University Hospitals, Turkey...

OBJECTIVES: Recently, following import by travel and migration, epidemic community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has caused nosocomial outbreaks in Europe, sometimes with a fatal outcome. We describe clinico-epidemiological characteristics of CA-MRSA detected by the European Network for the Surveillance of imported S. aureus (www. from May 2011- November 2016. METHODS: Sentinel surveillance at thirteen travel-clinics enrolling patients with travel-associated skin and soft tissue infection (SSTI) and analysing lesion and nose swabs at one central laboratory...
