#1
Jörn Diedrichsen, Nikolaus Kriegeskorte
Representational models specify how activity patterns in populations of neurons (or, more generally, in multivariate brain-activity measurements) relate to sensory stimuli, motor responses, or cognitive processes. In an experimental context, representational models can be defined as hypotheses about the distribution of activity profiles across experimental conditions. Currently, three different methods are being used to test such hypotheses: encoding analysis, pattern component modeling (PCM), and representational similarity analysis (RSA)...

STUDY DESIGN: A consecutive and prospective longitudinal study. OBJECTIVE: To propose an integrated multidimensional maturity assessment that was designated as forming a reliable system precisely predicting the high-risk occurrence of peak angle velocity (PAV) in a group of progressive braced female idiopathic scoliosis (IS).

BACKGROUND: To evaluate human papillomavirus (HPV) testing as a primary screening tool, we retrospectively analyzed data comparing (1) HPV testing to the algorithms of the ATHENA Study: (2) cytology alone, (3) cytology with ASCUS triage in women 25-29 and (4) cotesting ≥ 30 or (5) cotesting ≥ 25. METHODS: We retrospectively analyzed data from women tested with both cytology and HPV testing from 2010 to 2013. Cumulative risk (CR) for CIN3+ was calculated...

OBJECTIVE: To investigate an association between the awareness about the effects of tobacco consumption on oral health and the likelihood of smoking among male schoolchildren. MATERIALS AND METHODS: A cross sectional study was conducted using a multistage random sampling technique. The participants (ages 15-19 years) were recruited from male public high schools in Greater Dammam in Saudi Arabia. A pretested questionnaire inquired participants' awareness about the effects of smoking on oral health...

INTRODUCTION: Pathogenic belief is a central construct within control-mastery theory, which is an integrated dynamic-cognitive-relational approach in psychotherapy. Pathogenic beliefs result from traumatic life experiences and are considered the root of any psychological disorders presented clinically. Nevertheless, how and what type of pathogenic beliefs are attributed to clinical depressive disorder is unknown. The present study aimed to examine this issue. PATIENTS AND METHODS: Thirty patients with depressive disorder, who came for psychotherapy at a psychotherapy clinic, were matched based on age and gender with healthy controls who were medical students...

BACKGROUND: Asthma, dyspnea, and chronic cough are well-established risk factors of COPD and often associated with exacerbation of the disease, which is a leading cause of morbidity and mortality in South Asian countries. OBJECTIVE: The aims of this study were to, 1) measure the prevalence of asthma, dyspnea, and chronic cough, and 2) assess the relationship between these respiratory problems and self-reported health status among South Asians. METHODS: Data for this research came from the World Health Survey (2002-2003) conducted by the World Health Organization...

Previous studies in adults have shown that peripheral blood absolute lymphocyte and monocyte count ratio (ALC/AMC) after autologous stem cell transplant (ASCT) can predict outcome in patients with relapsed/refractory Hodgkin's lymphoma (R/R HL). We retrospectively reviewed all of our children, adolescent, and young adult (CAYA) patients (age ≤26) transplanted for R/R HL between 2004 and 2015. Seventy-six patients (median age 21, range 10-26 years) who reached d100 (d100) disease free were analyzed; 33% of them had PET-positive tumors prior to ASCT...

BACKGROUND: Some people are highly motivated to seek aggressive encounters, and among those who have been incarcerated for such behavior, recidivism rates are high. These observations echo two core features of drug addiction: high motivation to seek addictive substances, despite adverse consequences, and high relapse rates. Here we used established rodent models of drug addiction to determine whether they would be sensitive to "addiction-like" features of aggression in CD-1 mice. METHODS: In experiments 1 and 2, we trained older CD-1 mice to lever press for opportunities to attack younger C57BL6/J mice...

In mining environmental applications, it is important to assess water quality from waste rock piles (WRPs) and estimate the likelihood of acid rock drainage (ARD) over time. The mineralogical heterogeneity of WRPs is a source of uncertainty in this assessment, undermining the reliability of traditional bulk indicators used in the industry. We focused in this work on the bulk neutralizing potential ratio (NPR), which is defined as the ratio of the content of non-acid-generating minerals (typically reactive carbonates such as calcite) to the content of potentially acid-generating minerals (typically sulfides such as pyrite)...

This study examined data collected from U.S. public drinking water supplies in support of the recently-completed third round of the Unregulated Contaminant Monitoring Rule (UCMR3) to better understand the nature and occurrence of 1,4-dioxane and the basis for establishing drinking water standards. The purpose was to evaluate whether the occurrence data for this emerging but federally-unregulated contaminant fit with common conceptual models, including its persistence and the importance of groundwater contamination for potential exposure...

OBJECTIVE: Failure to rescue (FTR) is defined as the inability to rescue a patient from major perioperative complications, resulting in operative mortality. FTR is a known contributor to operative mortality after open abdominal aortic surgery. Understanding the causes of FTR is essential to designing interventions to improve perioperative outcomes. The objective of this study was to determine the relative contributions of hospital volume and safety-net burden (the proportion of uninsured and Medicaid-insured patients) to FTR...

BACKGROUND: Childhood obesity is increasing all over the world. Food insecurity is mentioned as a possible risk factor; however, previous studies have led to inconsistent results in different societies while data are lacking for the Middle East. We aimed to investigate the relationship between food insecurity and general or abdominal obesity in Iranian children in a cross-sectional study. METHODS: Anthropometric data including height, weight, and waist circumference were measured by trained nutritionists...
