The range of stimuli provided by physical space, toys and care practices contributes to the motor, cognitive and social development of children. However, assessing the quality of child education environments is a challenge, and can be considered a health promotion initiative. This study investigated the validity of the criterion, content, construct and reliability of the Affordances in the Home Environment for Motor Development - Infant Scale (AHEMD-IS), version 3-18 months, for the use in daycare settings...

AIMS: Low-grade ovarian endometrioid carcinomas may be associated with high-grade components. Whether the latter are clonally-related to and originate from the low-grade endometrioid carcinoma remains unclear. Here we employed massively parallel sequencing to characterize the genomic landscape and clonal relatedness of an ovarian endometrioid carcinoma containing low- and high-grade components. METHODS AND RESULTS: DNA samples extracted from each tumor component (low-grade endometrioid, high-grade anaplastic, high-grade squamous) and matched normal tissue were subjected to targeted massively parallel sequencing using the 410 gene Integrated Mutation Profiling of Actionable Cancer Targets (MSK-IMPACT) sequencing assay...

We numerically investigate spherically symmetric collapses in the Gross-Pitaevskii equation with attractive nonlinearity in a harmonic potential. Even below threshold for direct collapse, the wave function bounces off from the origin and may eventually become singular after a number of oscillations in the trapping potential. This is reminiscent of the evolution of Einstein gravity sourced by a scalar field in anti de Sitter space where collapse corresponds to black-hole formation. We carefully examine the long time evolution of the wave function for continuous families of initial states in order to sharpen out this qualitative coincidence which may bring new insights in both directions...

Classical ortho-phthalate plasticizers are, due to their endocrine disrupting potency and reproductive toxicity, increasingly replaced by alternative plasticizers. Di(2-ethylhexyl) terephthalate (DEHTP) is one of these substitutes. In this study, we investigated DEHTP exposure in 107 Portuguese children (4-17years old) by analyzing specific DEHTP metabolites in their urine using a newly developed LC-MS/MS method. We could detect the major, specific DEHTP metabolite mono(2-ethyl-5-carboxypentyl) terephthalate (5cx-MEPTP) in 100% of the samples with levels above the limit of quantification in 96% of the samples (median concentration 4...

Based on the observation of intense and offensive smells in the product group of aquatic toys, four representative products were exemplarily chosen and sensorially characterized by an expert panel. Panellists reported mostly almond- and rubber-like notes for three of the four samples, whereas the smell of the fourth sample was dominated by organic solvent-associated notes such as "nail polish-like." To elucidate the molecular reasons of these smells, we isolated the volatile fraction of the product by solvent extraction and high vacuum distillation, and identified the main odorants by aroma extract dilution analysis (AEDA), followed by one- and two-dimensional gas chromatography, with parallel mass spectrometric and olfactometric detection...

A toy example depicted here highlighting the results of a study in this issue of the Journal of Animal Ecology that investigates the impact of network dynamics on potential disease outbreaks. Infections (stars) that spread by contact only (left) reduce the predicted outbreak size compared to situations where individuals can become infected by moving through areas that previously contained infected individuals (right). This is potentially important in species where individuals, or in this case groups, have overlapping ranges (as depicted on the top right)...

The product formation yield (product formed per unit substrate consumed) is often the most important performance indicator in metabolic engineering. Until now, the actual yield cannot be predicted, but it can be bounded by its maximum theoretical value. The maximum theoretical yield is calculated by considering the stoichiometry of the pathways and cofactor regeneration involved. Here we found that in many cases, dynamic stability becomes an issue when excessive pathway flux is drawn to a product. This constraint reduces the yield and renders the maximal theoretical yield too loose to be predictive...

When the wave function of a large quantum system unitarily evolves away from a low-entropy initial state, there is strong circumstantial evidence it develops "branches": a decomposition into orthogonal components that is indistinguishable from the corresponding incoherent mixture with feasible observations. Is this decomposition unique? Must the number of branches increase with time? These questions are hard to answer because there is no formal definition of branches, and most intuition is based on toy models with arbitrarily preferred degrees of freedom...

A 12-year-old castrated Toy Poodle was referred to Kangwon National University Animal Hospital with an oligotrophic nonunion fracture in the left distal 1/3 of the radius and an intact ulna. After fixation using a locking plate and screws, adipose-derived mesenchymal stem cell sheets expressing bone morphogenetic protein 7 (BMP-7) were transplanted to the fracture site to enhance the healing activity. The fracture healed at 9 weeks after surgery. In the present case, the mesenchymal stem cell sheets expressing BMP-7 promoted bone regeneration and healing in a nonunion fracture...

INTRODUCTION: For Otorhinolaryngologist, removal of Foreign Bodies (FB) from the ear, nose and throat is one of the common emergency procedures done. Most of the cases especially of the ear and nose can be managed without General Anaesthesia (GA). But in some cases GA may be needed. There are very few studies that address the scenario of ear, nose and throat foreign body that required GA for its removal and the complications associated with it. AIM: This study was conducted with the aim to study the patient's profile, types and distribution of FB removed under GA, and the associated complications...

Vesicovaginal fistula (VVF) is commonly associated with obstetric trauma, but in developed nations it is typically iatrogenic. To date, there have been no published reports of VVF resulting from consensual sexual activity with sex toys. A 19-year-old gravida 0 presented with leakage of clear urine from the vagina following repetitive use of a sex toy with her female partner. The fistula was repaired in the operating room using a vaginal approach and a layered closure. This is the first case report of a VVF caused by consensual sex toy use between same-sex partners...

Choices made by cats between different types of environmental enrichment may help shelters to prioritize how to most effectively enrich cat housing, especially when limited by space or funds. This study investigates the environmental enrichment use of cats in a choice test. Twenty-six shelter cats were kept singularly in choice chambers for 10 days. Each chamber had a central area and four centrally-linked compartments containing different types of environmental enrichment: 1) an empty control, 2) a prey-simulating toy, 3) a perching opportunity, and 4) a hiding opportunity...

Neural correlates of face processing were examined in 12-month-olds at high-risk for autism spectrum disorder (ASD), including 21 siblings of children with ASD (ASIBs) and 15 infants with fragile X syndrome (FXS), as well as 21 low-risk (LR) controls. Event-related potentials were recorded to familiar and novel face and toy stimuli. All infants demonstrated greater N290 amplitude to faces than toys. At the Nc component, LR infants showed greater amplitude to novel stimuli than to their mother's face and own toy, whereas infants with FXS showed the opposite pattern of responses and ASIBs did not differentiate based on familiarity...

As Bayesian methods become more popular among behavioral scientists, they will inevitably be applied in situations that violate the assumptions underpinning typical models used to guide statistical inference. With this in mind, it is important to know something about how robust Bayesian methods are to the violation of those assumptions. In this paper, we focus on the problem of contaminated data (such as data with outliers or conflicts present), with specific application to the problem of estimating a credible interval for the population mean...

In hyperspectral image analysis, the classification task has generally been addressed jointly with dimensionality reduction due to both the high correlation between the spectral features and the noise present in spectral bands which might significantly degrade classification performance. In supervised classification, limited training instances in proportion to the number of spectral features have negative impacts on the classification accuracy, which has known as Hughes effects or curse of dimensionality in the literature...

With the wide range of applications, laser pointer used as toys by children becoming a major public safety problem worldwide. Here we present a long term followup of a ten-year-old boy retina injured patient who suffered from green light laser pointer. Retina injured patients caused by green light laser pointer were traditionally treated by steroid. We only gave Lutein treatment prescription according to the wishes of the patient's parents. After an over 12 months followup, the patient's visual acuity and retinal recovery situation, the outcomes are similar as cases with steroid treatment...
