Active lifestyles increase the risk of meniscal injury. A permanent meniscus implant of polycarbonate urethane (PCU) is a promising treatment to postpone/prevent total knee arthroplasty. Study of the changes in articular cartilage tribology in the presence of PCU is essential in developing the optimum meniscus implant. Therefore, a cartilage-meniscus reciprocating, sliding model was developed in vitro, mimicking the stance and swing phases of the gait cycle. The meniscus was further replaced with PCU and surface-modified PCUs (with C18 chains, mono-functional polydimethylsiloxane groups and mono-functional polytetrafluoroethylene groups) to study the changes...

Emotional interference control refers to the ability to remain focused on goal-oriented processes when confronted with disrupting but irrelevant emotional stimuli, a process that may be impaired in children and adults with attention deficit/hyperactivity disorder (ADHD). However, emotional interference levels are known to be associated with trait anxiety, and patients with ADHD often display elevated levels of trait anxiety, such as these may have confounded previous findings of decreased emotional interference control in this population...

Topographical disorientation (TD) is a neuropsychological condition characterized by an inability to find one's way, even in familiar environments. One common contributing cause of TD is landmark agnosia, a visual recognition impairment specific to scenes and landmarks. Although many cases of TD with landmark agnosia have been documented, little is known about the perceptual mechanisms which lead to selective deficits in recognizing scenes. In the present study, we test LH, a man who exhibits TD and landmark agnosia, on measures of scene perception that require selectively attending to either the configural or surface properties of a scene...

INTRODUCTION: Increased prevalence of nicotine dependence among individuals suffering from posttraumatic stress disorder (PTSD) is well established. However, there are limited studies on the prevalence of smoking during pregnancy in relation to prepregnancy history of trauma exposures and active PTSD symptoms during pregnancy. Prenatal smoking has been implicated in a host of negative outcomes for mother and baby. Given maternal and fetal risk, it is critical to define predictors of continued cigarette smoking during pregnancy...

The timing of puberty is a highly polygenic childhood trait that is epidemiologically associated with various adult diseases. Using 1000 Genomes Project-imputed genotype data in up to ∼370,000 women, we identify 389 independent signals (P < 5 × 10(-8)) for age at menarche, a milestone in female pubertal development. In Icelandic data, these signals explain ∼7.4% of the population variance in age at menarche, corresponding to ∼25% of the estimated heritability. We implicate ∼250 genes via coding variation or associated expression, demonstrating significant enrichment in neural tissues...

Imaging that fuses multiple modes has become a useful tool for diagnosis and therapeutic monitoring. As a next step, real-time fusion imaging has attracted interest as for a tool to guide surgery. One widespread fusion imaging technique in surgery combines real-time ultrasound (US) imaging and preacquired magnetic resonance (MR) imaging. However, US imaging visualizes only structural information with relatively low contrast. Here, we present a photoacoustic (PA), US, and MR fusion imaging system which integrates a clinical PA and US imaging system with an optical tracking-based navigation subsystem...

We analyzed the effects of bilingualism and age on executive function. We examined these variables along a continuum, as opposed to dichotomizing them. We investigated the impact that bilingualism and age have on two measures of executive control (Stroop and Flanker). The mouse-tracking paradigm allowed us to examine the continuous dynamics of the responses as participants completed each trial. First, we found that the Stroop effect was reduced with younger age and higher levels of bilingualism; however, no Bilingualism by Age interaction emerged...

Children's exposure to coparenting conflict has important implications for their developmental functioning, yet limited work has focused on such processes in families with diverse structures or ethnically and culturally diverse backgrounds. This longitudinal study examined the processes by which Mexican-origin adolescent mothers' coparenting conflict with their 3-year-old children's grandmothers and biological fathers (N = 133 families) were linked to children's academic and social skills at 5 years of age, and whether children's effortful control at 4 years of age mediated the link between coparenting conflict and indices of children's academic readiness...

OBJECTIVE: This review of empirical literature focuses on the design of operating rooms (ORs) by investigating the physical environmental features of ORs associated with patient and staff outcomes. BACKGROUND: Many ORs built more than 30 years ago remain operational today. However, most are inadequately designed to handle the equipment, processes, and people that a contemporary OR needs to accommodate. However, the evidence base for designing ORs has been sorely lacking, and little guidance exists on how OR design can improve safety and performance outcomes...

Language-based Learning Disabilities (LLDs) encompass a group of complex, comorbid, and developmentally associated deficits in communication. Language impairment and developmental dyslexia (DD) represent the most recognized forms of LLDs. Substantial genetic correlations exist between language and reading (dis)abilities. Common variants in the FOXP2 gene were consistently associated with language- and reading-related neuropsychological and neuroanatomical phenotypes. We tested the effect of a FOXP2 common variant, that is, rs6980093 (A/G), on quantitative measures of language and reading in two independent Italian samples: a population-based cohort of 699 subjects (3-11 years old) and a sample of 572 children with DD (6-18 years old)...

Muscle regeneration depends on satellite cells, quiescent precursors that, in consequence of injury or in pathological states such as muscular dystrophies, activate, proliferate, and differentiate to repair the damaged tissue. A subset of satellite cells undergoes self-renewal, thus preserving the satellite cell pool and its regenerative potential. Unacylated ghrelin (UnAG) is a circulating hormone that protects muscle from atrophy, promotes myoblast differentiation, and enhances ischemia-induced muscle regeneration...

Adolescence and emerging adulthood form a critical time period for the achievement of optimal health and nutrition across all stages of the life course. We undertook a review of published literature and global data repositories for information on nutrition levels, trends, and patterns among young people aged 10-24 years from January 1, 2016 to September 20, 2016. We describe patterns for both males and females at the global level and for geographic regions for the period covering 1990-2015. The results of this study paint a less than ideal picture of current young people's nutrition, suggesting dual burdens of underweight and high body-mass index in many countries and variable improvements in micronutrient deficiencies across geographical regions...

BACKGROUND: Chronic musculoskeletal pain is a major health problem among older adults, particularly those who live alone and/or those who are dependent on formal care. Chronic pain is associated with mobility problems, falls, fear of falling, catastrophizing thoughts, and a lower quality of life. Research shows that physical therapy interventions based on behavioral medicine approaches are beneficial for middle-aged adults with chronic pain. However, there appears to be no previous randomized controlled trials (RCTs) based on this theoretical framework that have examined the effect on older adults with chronic musculoskeletal pain who live alone at home and are dependent on formal care to manage their everyday lives...

OBJECTIVES: This study aimed to investigate sex differences in fear of pain (FOP) measured by the Fear of Pain Questionnaire III (FPQ-III) in a nonclinical sample. The FPQ-III is a self-report inventory measuring FOP, with 30 items, divided into three subscales: Severe, Minor and Medical Pain. METHODS: A total of 185 subjects participated (49.7% females) in this study. Sex differences on overall FOP, the subscales, and at item level were examined. One-way analysis of variance tested the association between sex and FOP, measured by overall FOP and the subscales...
