Background: Dirofilaria immitis is a cosmopolitan zoonotic, vector-borne parasite of carnivorous animals causing dirofilariasis in human beings. Common commercial serodiagnostic tests for canine dirofilariasis usually lead to different results in their sensitivity and specificity. The present study reports development of recombinant DgK (rDgK) antigen of D. immitis for accurate immunodiagnosis of D. Immitis-infected dogs using indirect ELISA test. Methods: The rDgK coding sequence was successfully sequenced, codon optimized and cloned in pET-24a(+) expression vector and then expressed in Escherichia coli...

Background: Brucellosis or Malta fever is a contagious infection common between human and domestic animals. Many antibiotics are used for brucellosis treatment, but they are not efficient and put heavy burden on society. Co-trimoxazole and rifampicin are two candidates for brucellosis treatment. In this study, we aimed to enhance the efficacy of these antibiotics using designed nanoparticles. Methods: Different concentrations of co-trimoxazole and rifampicin were used for loading onto a nanostructure of synthesized monomethoxy poly(ethylene glycol)-oleate (mPEG-OA)...

Juvenile idiopathic arthritis (JIA) is a wide group of diseases, characterized by synovial inflammation and joint tissue damage. Due to the delay in the implementation of biomarkers into clinical practice and the association with severe sequels, there is an imperative need for new JIA diagnosis strategies. Electrochemical biosensors based on screen-printed electrodes and peptides are promising alternatives for molecular diagnosis. In this work, a novel biosensor for detecting juvenile idiopathic arthritis (JIA) was developed based on the immobilization of the PRF+1 mimetic peptide, as recognition biological element, on the surface of screen-printed carbon electrode...

The objective of the present study was to develop a one-pot strategy to synthesis gold nanoparticle complexes using cinnamaldehyde, a potent antibiofilm agent which in its free form, exhibits high volatility and unstable nature. Hence, we developed cinnamaldehyde gold nanoparticles (CGNPs) in a single step to overcome the limitations of free cinnamaldehyde. Furthermore, reduction abilities of cinnamaldehyde under different experimental conditions, that is, varying precursor concentrations of cinnamaldehyde and gold, metal salts, pH, temperature, and light sources, were investigated...

Oxidative potential (OP) of particulate matter (PM) is proposed as a biologically-relevant exposure metric for studies of air pollution and health. We aimed to evaluate the spatial variability of the OP of measured PM2.5 using ascorbate (AA) and (reduced) glutathione (GSH), and develop land use regression (LUR) models to explain this spatial variability. We estimated annual average values (m(-3)) of OP(AA) and OP(GSH) for five areas (Basel, CH; Catalonia, ES; London-Oxford, UK (no OP(GSH)); the Netherlands; and Turin, IT) using PM2...

Azithromycin (AZ) is a widely-used macrolide antibiotic that is continually deposited into natural waterways by sewage effluent. Though recognized as an emerging contaminant of concern, little is known about its fate and transport in aquatic systems. American River soils and water were used to determine degradation of AZ in microcosms simulating flooded (anaerobic) and non-flooded (aerobic) California watershed conditions. Under aerobic conditions the degradation rate constant (k=0.0084 ± 0.0039 day(-1)) and DT50 (82...

BACKGROUND: The Hamilton Depression Rating Scale (HAM-D) and the Montgomery Asberg Depression Rating Scale (MADRS) are scales used frequently to rate the symptoms of depression. There are many situations in which it is important to know what a given total score or a percent reduction from baseline score of one scale means in relation to the other scale. METHOD: We used the equipercentile linking method to identify corresponding scores of simultaneous HAM-D and MADRS ratings in 4388 patients from 31 mirtazapine trials in major depressive disorder...

DNA polymerase λ (Pol λ) is the only member of DNA polymerase family X present in plants. The enzyme is ddNTP sensitive as it contains the conserved C-terminal Pol β domain. The 1.1 kb partial coding sequence isolated spanned the whole 3' regions of the gene containing functionally important domains of the Pol λ gene. Comparative in silico studies from both indica and japonica cultivars involving homology modelling showed that the model for the partial Pol λ gene was stable and acceptable. The alignment of both the protein models showed a RMS value of 0...

Used Latex gloves found at crime scenes can provide strong evidence against a suspect as they almost certainly contain both the fingermarks and DNA of the perpetrator who had worn them. However, over the years, Latex gloves have proved to be a rather difficult substrate for fingermarks development, with most of the standard techniques producing poor results. In this study, the two main protocols for development on either porous or non-porous surfaces: Ninhydrin-HFE and superglue fuming followed by crystal violet (CV) dyeing, respectively, had been examined on 100 disposable Latex gloves from twenty five donors...

This is an exploratory study into the need for additional lines of forensic evidence in humanitarian cases using applied research. One hundred and twenty four, still unidentified terrorism inmates, were killed after surrendering to the Peruvian Army once it took control of the San Pedro-Lurigancho prison in Lima, Peru in 1986. Two questions are put forward: first, to what extent mechanism of injury (gunshot, blunt, sharp force) and bodily distribution of those injuries allow us to classify individuals into discrete sub-groups of people? The second question is to what respect can such a classification become an additional line of evidence assisting in generating hypotheses of identity regarding those individuals? The analysis of the 109 recovered bodies and their associated evidence show a sub group of four individuals differentiated from the rest based on the combination of injuries (gunshot and blunt force trauma), opposing trajectories and weapons...

Novel hydrated zirconium oxide (ZrO(OH)2) coated carbon nanotubes (CNTs) were prepared via a filtration-steam hydrolysis method, and were used to remove As(III) and As(V) from drinking water. This adsorbent was characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM). The ZrO(OH)2 coated on the surface of CNTs was amorphous, and the coating thickness was in the range of 1-8 nm. The ZrO(OH)2/CNTs nanocomposite showed high adsorption for both As(III) and As(V) with the maximum adsorption capacities of 78...
