PURPOSE: Absorbed radiation dose-response relationships are not clear in molecular radiotherapy (MRT). Here, we propose a voxel-based dose calculation system for multicellular dosimetry in MRT. We applied confocal microscope images of a spherical cell aggregate i.e. a spheroid, to examine the computation of dose distribution within a tissue from the distribution of radiopharmaceuticals. METHODS: A confocal microscope Z-stack of a human hepatocellular carcinoma HepG2 spheroid was segmented using a support-vector machine algorithm and a watershed function...

The treatment of pediatric high-risk neuroblastoma is intensive and multimodal. Despite the introduction of immunotherapy for minimal residual disease, survival rates remain suboptimal and new therapies are needed. As part of a phase 2 trial, we are using a consolidation therapy regimen which combines a busulfan/melphalan conditioning schema, autologous hematopoietic cell transplant (AHCT), and experimental immunotherapy with hu14.18K322A (a humanized anti-GD2 monoclonal antibody), GM-CSF, and IL-2, with or without the adoptive transfer of haploidentical natural killer cells (NKs)...

This paper explores the approaches adopted by high-level field athletics coaches when attempting to refine an athlete's already well-established technique (long and triple jump and javelin throwing). Six coaches, who had all coached multiple athletes to multiple major championships, took part in semi-structured interviews focused upon a recent example of technique refinement. Data were analysed using a thematic content analysis. The coaching tools reported were generally consistent with those advised by the existing literature, focusing on attaining "buy-in", utilising part-practice, restoring movement automaticity and securing performance under pressure...

Chia-Kuei Lee, Karen F Stein, Colleen Corte
BACKGROUND: Co-occurrence of drinking and smoking is prevalent in undergraduate students. A drinker self-schema - cognition about the self as the drinker - is a common identity in undergraduates and a well-known predictor of drinking behaviors. Given that smoking commonly occurs in the context of drinking, a drinker self-schema may be a cognitive mechanism to motivate co-occurring alcohol and tobacco use (i.e., cross-substance facilitation hypothesis). This study was to determine whether the drinker self-schema influences the processing of drinking- and smoking-related information and facilitates the co-occurrence of alcohol and tobacco use in undergraduate students who drink and smoke but do not self-identify as smokers...

Considering the association between children's quality of relationships with teachers and their academic adjustment, information pertaining to how abused children are functioning in their relationships with teachers could be useful in promoting their academic success- yet there has been limited research in this area. The purpose of this study was to use cluster analyses to explore within-group differences in relational schemas and quality of student-teacher relationships for 70 abused children. Two clusters of abused children emerged, and as hypothesized, there were significant differences in student-teacher relationships for the two clusters...

Research has primarily focused on the consequences of the female thin ideal on women and has largely ignored the effects on men. Two studies were designed to investigate the effects of a female thin ideal video on cognitive (Study 1: appearance schema, Study 2: visual-spatial processing) and self-evaluative measures in male viewers. Results revealed that the female thin ideal predicted men's increased appearance schema activation and poorer cognitive performance on a visual-spatial task. Constructs from self-determination theory (i...

Cognitive processes related to schema acquisition comprise an essential source of demands in learning situations. Since the related amount of cognitive load is supposed to change over time, plausible temporal models of load progression based on different theoretical backgrounds are inspected in this study. A total of 116 student participants completed a basal symbol sequence learning task, which provided insights into underlying cognitive dynamics. Two levels of task complexity were determined by the amount of elements within the symbol sequence...

Yuqi Liu, Jared Medina
When placing one hand on each side of a mirror and making synchronous bimanual movements, the mirror-reflected hand feels like one's own hand that is hidden behind the mirror. We developed a novel mirror box illusion to investigate whether motoric, but not spatial, visuomotor congruence is sufficient for inducing multisensory integration, and importantly, if biomechanical constraints encoded in the body schema influence multisensory integration. Participants placed their hands in a mirror box in opposite postures (palm up, palm down), creating a conflict between visual and proprioceptive feedback for the hand behind the mirror...

Prior knowledge can either assist or hinder the ability to learn new information. These contradicting behavioral outcomes, referred to as schema benefit and proactive interference respectively, have been studied separately. Here we examined whether the known neural correlates of each process coexist, and how they are influenced by attentional loading and aging. To this end we used an fMRI task that affected both processes simultaneously by presenting pairs of related short movies in succession. The first movie of each pair provided context for the second movie, which could evoke schema benefit and/or proactive interference...

PURPOSE: Despite increasing interest in incident learning systems (ILS) to improve safety and quality in radiation oncology, little is known about interventions developed in response to safety data. We used total body irradiation (TBI) as a model system to study the effectiveness of interventions from our institutional ILS. METHODS AND MATERIALS: Near-miss event reports specific to TBI were identified from a departmental ILS from March 2012 to December 2015. The near-miss risk index was rated at multidisciplinary review from 0 (no potential harm) to 4 (critical potential harm)...

According to the schema theory, variability during practice allows for a larger repertoire of movements to help form a generalized motor program for similar motor skills. Varied training is thought to enhance long-term retention of the motor program due to the heightened difficulty presented. In a highly cited study on this topic, Kerr and Booth (Perceptual and Motor Skills 46 (1978), 395-401) trained two groups of children for 10weeks to throw a beanbag towards either one central target (specific group) or two targets that were ±1 foot away from the central target (varied group)...

There are few studies on suicidal risk and its related factors in patients diagnosed with obsessive-compulsive disorder (OCD). This study investigated the associations of early maladaptive schemas, OC symptom dimensions, OCD severity, depression and anxiety with suicidality (i.e., suicidal ideation and suicide attempts) in OCD patients. Sixty OCD outpatients completed the Scale for Suicide Ideation (SSI), the Young Schema Questionnaire-Short Form (YSQ-SF), the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), the Dimensional Obsessive-Compulsive Scale (DOCS) and the Depression Anxiety Stress Scales (DASS-21)...

Anxiety is common in the context of cancer, but there are few theoretical models that apply to people with cancer across the trajectory of their illness. The aims of this review are to identify existing theories and to propose an integrated model of cancer-related anxiety. Using a systematic literature search of Medline, Premedline and PsycINFO databases, we identified nine theoretical models of anxiety in the context of cancer. We reviewed these for psychological concepts that fell under five themes: pre-existing schema, the inherent nature of cancer, cognitive factors, coping responses and contextual factors...

The current study aims to identify the relationships between implicit leadership theoretical (ILT) prototypes / anti-prototype and five facial features (i.e., nasion, upper nose, lower nose, and upper lip) of a leader from a different race than respondents. A sample of 81 Asian respondents viewed a 30-second video of a Caucasian female who in a non-engaging manner talked about her career achievements. As participants watch the video, their eye movements were recorded via an eye tracking devise. While previous research has identified that ILT influences perceptional and attitudinal ratings of leaders, the current study extends these findings by confirming the impact of ILT on the gaze patterns of other race participants, who appear to adopt system one type thinking...

PURPOSE: Catheter-based ultrasound applicators can generate thermal ablation of tissues adjacent to body lumens, but have limited focusing and penetration capabilities due to the small profile of integrated transducers required for the applicator to traverse anatomical passages. This study investigates a design for an endoluminal or laparoscopic ultrasound applicator with deployable acoustic reflector and fluid lens components, which can be expanded after device delivery to increase the effective acoustic aperture and allow for deeper and dynamically adjustable target depths...

REVIEW
Victor Pitron, Frédérique de Vignemont
The distinction between the body schema and the body image has become the stock in trade of much recent work in cognitive neuroscience and philosophy. Yet little is known about the interactions between these two types of body representations. We need to account not only for their dissociations in rare cases, but also for their convergence most of the time. Indeed in our everyday life the body we perceive does not conflict with the body we act with. Are the body image and the body schema then somehow reshaping each other or are they relatively independent and do they only happen to be congruent? On the basis of the study of bodily hallucinations, we consider which model can best account for the body schema/body image interactions...
