Peripheral nerve sheath tumors are a heterogeneous group of neoplasms that comprise neurofibromas, schwannomas, neurilemmomas, and perineuromas. In animals, peripheral nerve sheath neoplasms are most commonly diagnosed in dogs and cattle, followed by horses, goats, and cats, but their occurrence is uncommon in birds. An adult, free-living, male toco (common) toucan ( Ramphastos toco ) was admitted to the zoo animal clinic with weight loss, dehydration, and presence of a soft nodule adhered to the medial portion of the left pectoral muscle...

We tested the hypothesis that in atrial myocytes from a rabbit left ventricular heart failure (HF) model, spatial inhomogeneity and temporal dyssynchrony of Ca removal during excitation-contraction coupling together with increased Na/Ca exchange (NCX) activity generates a substrate for proarrhythmic Ca release. Ca removal occurs via Ca reuptake into the sarcoplasmic reticulum and extrusion via NCX exclusively in the cell periphery since rabbit atrial myocytes lack transverse tubules. Ca removal kinetics were assessed by the time constant τ of decay of local peripheral subsarcolemmal (SS) and central (CT) action potential (AP) induced Ca transients (CaTs) recorded in confocal line scan mode (using Fluo-4)...

BACKGROUND: Immunomodulatory interventions play a key role in the treatment of infections and cancer as well as allergic diseases. Adjuvants such as micro- and nanoparticles are often added to immunomodulatory therapies to enhance the triggered immune response. Here, we report the immunological assessment of novel and economically manufactured microparticle adjuvants, namely strontium-doped hydroxyapatite porous spheres (SHAS), which we suggest for the use as adjuvant and carrier in allergen-specific immunotherapy (ASIT)...

The physicochemical and biological properties of metals change as the particles are reduced to nanoscale. This ability increases the application of nanoparticles in commercial and medical industry. Keeping in view this importance, Silver nanoparticles (Ag-NPs) were synthesized by reduction methods using formaldehyde as reducing agent in the chemical route and lemon extracts in the biological route. The scanning electron microscope (SEM) images of nanoparticles suggested that the particles were either agglomerated or spherical in shape with mean diameter of 16...

OBJECTIVES: Dermatophytosis, commonly known as ringworm, is a superficial fungal skin disease and zoonosis. Pythium oligandrum is a micromycete with mycoparasitic properties that is used in agriculture to control fungal infections on plants. Formulations containing P oligandrum were also developed for the treatment of dermatophytoses, but only several case studies have been published. In order to document the process in simplified conditions in vitro, we investigated the effectiveness of P oligandrum against three pathogenic dermatophytes common in domestic animals...

The presence of ZnO nanoparticles (ZnO NPs) in natural waters has raised concerns about their environmental impacts, but the potential influences of ZnO NPs on fluvial biofilm have not been reported. In this study, the utility of antioxidant enzyme activities (AEA) as biomarkers of fluvial biofilm to ZnO NPs toxicity and a method that combines AEA into an index of "Integrated Biomarker Responses (IBR)" were studied. Compared with the absence of ZnO NPs, scanning electron microscopy (SEM) images revealed that a large amount of ZnO NPs were adsorbed onto biofilm and these NPs exerted adverse effects on the viability of bacteria in biofilm...

Inverse CeO₂-Co₃O₄/CuO catalysts with chrysanthemum-like morphology were prepared by the co-precipitation method, and characterized via scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), temperature-programmed reduction (H2-TPR), and N2 adsorption-desorption techniques. It is found that the filament is composed of ordered-array CuO nanocrystallites, and CeO₂ was dispersed on the outer surface of filament. The CeO₂-Co₃O₄/CuO catalyst with thin filaments can form the long periphery at the CeO₂-CuO contact interface and improve catalytic performance...

INTRODUCTION: Previous studies have indicated that orthodontic-grade cone-beam computed tomography (CBCT) images are limited when displaying small defects at the mandibular condyles for diagnosis. In this study, we investigated whether this limitation was inherent to CBCT by comparing CBCT with multislice computed tomography (CT), and whether image segmentation and color mapping could overcome this limitation. METHODS: Nine fresh pig heads (18 condyles, 36 medial and lateral condylar regions) were used...

Inconsistent dosage of insulin (INS) for type 2 diabetes patients lead to severe adverse effects like limb amputation, blindness and fatal hypo or hyper glycaemia. Hence, a drug delivery system (DDS) capable of consistent INS release by sensing changes in blood glucose level is essential. Herein, we report a glucose responsive DDS comprised of oleic acid-grafted-aminated beta cyclodextrin (OA-g-ACD) copolymer, coated with a dispersion of glucose oxidase (GOx) and catalase (CAT). The prepared DDS was characterised using FTIR, Optical Microscopy, H(1) NMR, DLS and SEM...

This study estimated the basic reproductive ratio of rabies at the population level in wild animals (foxes), farm animals (cattle, camels, horses, sheep) and what we classified as domestic animals (cats, dogs) in the Republic of Kazakhstan (RK). It also aimed at forecasting the possible number of new outbreaks in case of emergence of the disease in new territories. We considered cases of rabies in animals in RK from 2010 to 2013, recorded by regional veterinary services. Statistically significant space-time clusters of outbreaks in three subpopulations were detected by means of Kulldorff Scan statistics...
