This article presents findings from a qualitative research study exploring the experiences of early intervention practitioners in a reflective consultation program. Fifteen licensed early childhood special education teachers and speech, occupational, and physical therapists as well as a psychologist from an urban school district participated in interviews discussing their work stressors and involvement with monthly reflective consultation groups. They described a loosely temporal, iterative process which transformed how they thought and felt about both themselves as practitioners and the children and families with whom they worked...

The orbital aperture is the entrance to the orbit in which most important visual structures such as the eyeball and the optic nerve are found. It is vital not only for the visual system but also for the evaluation and recognition of the face. Eyeball volume is essential for diagnosing microphthalmos or buphthalmos in several eye disorders. Knowing the length of the optic nerve is necessary in selecting the right instruments for enucleation. Therefore, the aim of this study was to evaluate eyeball volume, orbital aperture, and optic nerve dimensions for a morphological description in a Turkish population sample according to gender and body side...

BACKGROUND: This experimental study provides a qualitative description and the morpho-structural features of the fusions taking place in the thoracic spine between prepubertal age and skeletal maturity. There is a lack of informations regarding the influence of partial or total dorso-thoracic vertebral arthrodesis on the development of the thoracic cage as well as its potential effects on different intra and extra-thoracic organs. This study admits the hypothesis that vertebral arthrodesis may have influence on other body areas and so, it intends to verify the possible secondary involvement of other body parts, such as intervertebral discs, cervical and thoracic spinal ganglia, sternocostal cartilage, ovaries and lungs...

The room temperature structure of Ba5AlF13 has been investigated by coupling electron, synchrotron and neutron powder diffraction, solid-state high-resolution NMR ((19)F and (27)Al) and first principles calculations. An initial structural model has been obtained from electron and synchrotron powder diffraction data, and its main features have been confirmed by one- and two-dimensional NMR measurements. However, DFT GIPAW calculations of the (19)F isotropic shieldings revealed an inaccurate location of one fluorine site (F3, site 8a), which exhibited unusual long F-Ba distances...

Although mammalian vocalizations are predominantly harmonically structured, they can exhibit an acoustic complexity with nonlinear vocal sounds, including deterministic chaos and frequency jumps. Such sounds are normative events in mammalian vocalizations, and can be directly traceable to the nonlinear nature of vocal-fold dynamics underlying typical mammalian sound production. In this study, we give qualitative descriptions and quantitative analyses of nonlinearities in the song repertoire of humpback whales from the Ste Marie channel (Madagascar) to provide more insight into the potential communication functions and underlying production mechanisms of these features...

BACKGROUND: Cephalopods are a highly derived class of molluscs that adapted their body plan to a more active and predatory lifestyle. One intriguing adaptation is the modification of the ventral foot to form a bilaterally symmetric arm crown, which constitutes a true morphological novelty in evolution. In addition, this structure shows many diversifications within the class of cephalopods and therefore offers an interesting opportunity to study the molecular underpinnings of the emergence of phenotypic novelties and their diversification...

BACKGROUND: Obesity is a well-established independent risk factor for hypertension and other cardiometabolic disorders. However, the best anthropometric index of obesity that predicts or associates strongly with hypertension and related conditions remains controversial and inconclusive. OBJECTIVE: This study compared the performance of eight anthropometric indices of obesity: body mass index (BMI), ponderal index (PI), waist circumference (WC), hip circumference (HC), waist-hip ratio (WHR), waist-height ratio (WHtR), body adiposity index (BAI) and conicity index (CI) as correlates and potential predictors of risk of hypertension and prehypertension in a Nigerian population, and also the possible effect of combining two or more indices in that regard...

A new species of darkling beetles Blaps caspica sp. n. from Western Kazakhstan Kulaly Island (Tyuleniy Archipelago, Caspian Sea) is described. This new taxon belongs to the 6<sup>th</sup> group of the 2<sup>nd</sup> section according to Seidlitz's classification and is most similar to Blaps kadyrbekovi G. Medvedev, 2004, B. lethifera Marsham, 1802 and B. parvicollis Zoubkoff, 1829. Blaps caspica sp. n. differs from B. kadyrbekovi by the presence of a hair tuft between male abdominal ventrites 1 and 2, from B...

Although spine variation within cacti species or populations is assumed to be large, the minimum sample size of different spine anatomical and morphological traits required for species description is less studied. There are studies where only 2 spines were used for taxonomical comparison amnog species. Therefore, the spine structure variation within areoles and individuals of one population of Gymnocalycium kieslingii subsp. castaneum (Ferrari) Slaba was analyzed. Fifteen plants were selected and from each plant one areole from the basal, middle and upper part of the plant body was sampled...

Anatomy as a descriptive topic of research and instruction in medicine has been increasingly influenced by discoveries in molecular cell and developmental biology and most recently the advent of human induced pluripotent stem cells and organoids. We summarize here how anatomy has been influenced by developmental and stem cell biologists, and how in vitro modelling of the three-dimensional body environment is emerging to understand structure and function of cells during differentiation processes in development and disease...

Ossification is a tightly regulated process, performed by specialized cells called osteoblasts. Dysregulation of this process may cause inadequate or excessive mineralization of bones or ectopic calcification, all of which have grave consequences for human health. Understanding osteoblast biology may help to treat diseases such as osteogenesis imperfecta, calcific heart valve disease, osteoporosis, and many others. Osteoblasts are bone-building cells of mesenchymal origin; they differentiate from mesenchymal progenitors, either directly or via an osteochondroprogenitor...

BACKGROUND: There are many well-established national health care-associated infection surveillance programs (HAISPs). Although validation studies have described data quality, there is little research describing important characteristics of large HAISPs. The aim of this study was to broaden our understanding and identify key characteristics of large HAISPs. METHODS: Semi-structured interviews were conducted with purposively selected leaders from national and state-based HAISPs...

This paper explores the relevance and feasibility of enhanced surveillance of mussel-related mortality based on regular telephone interviews of a key informant in a farming community. Based on qualitative analyses of data collected through semi-structured interviews, this method of participatory disease surveillance enabled the retrieval of high quality data during an outbreak of mussel mortality which occurred in Pertuis Charentais, France, in 2014. The findings illustrated that such an enhanced surveillance approach compared with the institutional shellfish health surveillance system could improve the early detection of outbreaks of mussel mortality by one week...

INTRODUCTION: Individuals with schizophrenia, particularly those with passivity symptoms, often feel that their actions and thoughts are controlled by an external agent. Recent evidence has elucidated the role of body representations in the aetiology of passivity symptoms, yet one representation - body structural description - has not yet been examined. Additionally, body image has rarely been examined outside of bodily illusions (e.g., rubber hand experiments) and external validation is required...

Maximal oxygen uptake (VO2max), fractional utilization of VO2max during running and running economy (RE) are crucial factors for running success for all endurance athletes. Although evidence is limited, investigations of these key factors indicate that the East Africans superiority in distance running is to a large exent due to a unique combination of these factors. East African runners appear to have a very high level of RE most likely associated, at least partly, with anthropometric characteristics rather than with any specific metabolic property of the working muscle...

On the basis of a general symmetry analysis, this paper presents an empirical tight-binding (TB) model for the reference Pm-3m perovskite cubic phase of halide perovskites of general formula ABX3. The TB electronic band diagram, with and without spin orbit coupling effect of MAPbI3 has been determined based on state of the art density functional theory results including many body corrections (DFT+GW). It affords access to various properties, including distorted structures, at a significantly reduced computational cost...

The second- and third-instar larvae of the South African species of Mastigini, Stenomastigus longicornis, are described. The serial homology of chaetotaxic structures and differences between larval instars are discussed. The larva of Stenomastigus is very similar to that of Palaeostigus, but differences in proportions of body parts, number of setae on the head, thorax and abdomen and possibly also the shape of the antennal sensory appendage can be used to distinguish them. A frontal impression surrounded by modified setae with greatly enlarged surface, presumably functioning as a glandular evaporation apparatus, and the antennomere II subdivided into three sections, are suggested as synapomorphies of Mastigini; within Mastigitae this tribe is also unique in lacking the urogomphs, which are present in larvae of Leptomastacini and Clidicini...

In a subset of patients, infantile hemangiomas may be associated with structural anomalies. Structural anomalies may affect the upper body (PHACE Syndrome) or the lower body (LUMBAR Syndrome). Since their initial descriptions, improved understanding of these two syndromes has lead to recognition of a broader phenotypic spectrum than initially recognized. This paper aims to provide an updated review of the presentation, associated anomalies, and management of PHACE and LUMBAR syndromes, two well-characterized syndromes associated with IH...
