Child maltreatment remains a serious public health issue in the United States. Therefore, it is important to engage in quality control of the assessment, prevention, and treatment services for families affected by maltreatment. Parenting capacity assessments (PCAs) are typically an integral part of service delivery for families affected by maltreatment and can carry serious consequences for the referred parent. The Child Abuse Potential Inventory (CAPI) is a measure that is widely used in PCAs; however, socially desirable responding on the CAPI can serve to invalidate the important information derived from this assessment, as well as lead to negative impressions of the parent...

The contamination profiles of sixteen perfluoroalkyl substances (PFAS) were examined in coral reef fish samples collected from the South China Sea (SCS) where no information about this topic was available in the literature. The results revealed that six PFAS were found in coral reef fish samples from the SCS. Perfluorooctane sulfonate (PFOS) was the most predominant PFAS contaminant detected in most of the samples, with the highest concentration value of 27.05 ng/g wet weight (ww) observed in Cephalopholis urodelus...

The presence of genital inflammatory responses and a compromised vaginal epithelial barrier have been linked to an increased risk of HIV acquisition. It is important to assure that application of candidate microbicides designed to limit HIV transmission will not cause these adverse events. We previously developed high resolution in vivo imaging methodologies in sheep to assess epithelial integrity following vaginal application of a model microbicide, however characterization of genital inflammation in sheep has not been previously possible...

This study evaluated the effect of temperature on methane production by CO2 reduction during microbial electrosynthesis (MES) with a mixed-culture biocathode. Reactor performance, in terms of the amount and rate of methane production, current density, and coulombic efficiency, was compared at different temperatures. The microbial properties of the biocathode at each temperature were also analyzed by 16S rRNA gene sequencing. The results showed that the optimum temperature for methane production from CO2 reduction in MES with a mixed-culture cathode was 50°C, with the highest amount and rate of methane production of 2...

This study firstly evaluated the microbial role when choosing the acclimated anaerobic granular sludge (AGS) and waste activated sludge (WAS) as microbial and nutritional regulators to improve the biomethanation of fruit and vegetable wastes (FVW). Results showed that the enriched hydrogenotrophic methanogens, and Firmicutes and Spirochaeta in the AGS were responsible for the enhanced methane yield. A synthetic waste representing the mixture of WAS and FVW was then used to investigate the influences of different substrate composition on methane generations...

The pioneering study of Eyal-Giladi and Kochav (EG&K; Eyal-Giladi and Kochav, 1976) on the early developmental stages-from fertilization, through oviposition, to the gastrulation process-set the standard for characterizing chicken embryos, and has been used in numerous studies over the years. During uterine development, the chicken embryo undergoes dramatic changes, extremely rapid cell cycles, massive cell death, and axial determination processes. However, once the egg is laid, the temperature drops and the embryo enters into a diapause-like state...

β-galactomannans found in soy-based broiler feed are known to cause physiological effects that are hypothesized to be related to gut inflammation. Previous studies have shown that the incorporation of β-mannanase in the diet or as a supplement results in improvements to certain performance parameters related to gut health and feed conversion. Using kinome analysis, we characterized the mechanism of β-galactomannan activity and supplementation with β-mannanase on the gut of commercial broilers to understand the mode of action...

Movement disorders are a prominent and common feature in many autoantibody-associated neurological diseases, a group of potentially treatable conditions that can mimic infectious, metabolic or neurodegenerative disease. Certain movement disorders are likely to associate with certain autoantibodies; for example, the characteristic dyskinesias, chorea and dystonia associated with NMDAR antibodies, stiff person spectrum disorders with GAD, glycine receptor, amphiphysin or DPPX antibodies, specific paroxysmal dystonias with LGI1 antibodies, and cerebellar ataxia with various anti-neuronal antibodies...

The ability to monitor biomolecular reactions in a real-time and label free manner is nearly synonymous with the surface plasmon resonance (SPR) technique. At its basis, SPR relies on the interaction of an incoming light source with a thin metallic film in close contact with a prism or grating, which, under the correct experimental conditions, allows for the propagative oscillation of the conduction electrons at the surface of the metallic material. The oscillating, electromagnetic fields are extremely sensitive to small changes in the refractive index within the dielectric near the sensing interface, where various binding events and interactions can be detected...

G protein-coupled receptors (GPCR) exhibit the ability to form receptor complexes that include molecularly different GPCR (i.e. GPCR heteromers), which endow them with singular functional and pharmacological characteristics. The relative expression of GPCR heteromers remains a matter of intense debate. Recent studies support that adenosine A2A receptors (A2A R) and dopamine D2 receptors (D2 R) predominantly form A2A R-D2 R heteromers in the striatum. The aim of the present study was evaluating the behavioral effects of pharmacological manipulation and genetic blockade of A2A R and D2 R within the frame of such a predominant striatal heteromeric population...

The relevance of this study is the high prevalence and clinical heterogeneity of deficit states in chronic schizophrenia and schizophrenia spectrum disorders. The study aimed at analyzing negative symptoms in schizophrenia and schizophrenia spectrum disorders from historical and modern perspectives. An analysis of available literature, along with own observations, has been performed. It was found that negative symptoms comprise 3 clinical types: 1) 'pseudopsychopathic' type (overlapping personality dimensions and premorbid/initial negative symptoms), 2) pseudoorganic/asthenic/pseudobradiphrenic type (pseudoorganic states), developing at different stages of schizophrenia), 3) 'new'-life pseudopsychopathic type (not associated with premorbid personality traits), developing at late stages in schizophrenia...

A major review of the literature of syringocystadenoma papilliferum's (SCAP's) presentation and management is presented. In addition, a case report of this unique diagnosis presenting as a corneal abrasion in a 66-year-old-male is included. This benign adnexal tumor of the apocrine glands is most commonly found in the face and neck. When found on the eyelids, these lesions are commonly misdiagnosed as basal cell carcinoma or cysts. Diagnosis is made based on histopathology. Treatment is complete excision of the lesion and this has a low recurrence rate...

Lignin is the most abundant phenolic polymer; thus, its decomposition by microorganisms is fundamental to carbon cycling on earth. Lignin breakdown is initiated by depolymerization catalyzed by extracellular oxidoreductases secreted by white-rot basidiomycetous fungi. On the other hand, bacteria play a predominant role in the mineralization of lignin-derived heterogeneous low-molecular-weight aromatic compounds. The outline of bacterial catabolic pathways for lignin-derived bi- and monoaryls are typically composed of the following sequential steps: i) funneling of a wide variety of lignin-derived aromatics into vanillate and syringate, ii) O demethylation of vanillate and syringate to form catecholic derivatives, and iii) aromatic ring-cleavage of the catecholic derivatives to produce tricarboxylic acid cycle intermediates...

A cost-effective hexagonal sphericon hematite with predominant (110) facets for the oxygen evolution reaction (OER) is demonstrated. Sequential incorporation of near-atomic uniformly distributed Ce species and Ni nanoparticles into selected sites of the hematite induces a complex synergistic integration phenomenon that enhances the overall catalytic OER performance. This cheap hexagonal sphericon hematite (Fe ≈ 98%) only needs a small overpotential (η) of 0.34 V to reach 10 mA cm(-2) , superior to commercial IrO2 and more expensive Co-, Ni-, and Li-based electrocatalysts...

Swallowing impairment (dysphagia) is a common sequela in patients with motor neuron disease (MND). The purpose of this retrospective, observational pilot investigation was to characterize how pharyngeal swallowing mechanics are impacted in patients with MND using a comparison with healthy, non-dysphagic control group. Computational analysis of swallowing mechanics (CASM) was used to determine covariate biomechanics of pharyngeal swallowing from videofluoroscopic assessment in 15 patients with MND and 15 age- and sex-matched healthy controls...
