Younger siblings of children with ASD often exhibit elevated internalizing and externalizing problems. We investigated common dopaminergic variants (DRD4 and DRD2) in relation to behavior problems at 36 months. Genotypes linked to less efficient dopaminergic functioning were associated with higher internalizing problems in high-risk siblings.

The boundary between occupational and environmental exposures is often artificial, as occupational hazards can readily escape the workplace. One way that this occurs is when workers "take-home" occupational hazards, exposing family members. While take-home exposures have long been recognized, there is no comprehensive framework describing the pathways by which workers bring home workplace hazards. In this work we provide such a conceptual model that includes three pathways for take-home exposures: external contamination, internal dose and behavior change of workers...

OBJECTIVES: Pedestrian crashes are a critical problem in Latin American countries. However, little research has been published about pedestrians and even less about their behaviors in a naturalistic context. The objective of the present research was to explore risky pedestrian crossing behaviors in traffic intersections in an argentine city (Ushuaia). It is focused in different stages of the crossing process, traffic code violations, and other potentially risky behaviors such as distractions...

High levels of heavy metals like copper ions in many industrial based effluents lead to serious environmental and health problems. Biosorption is a potential environmental biotechnology approach for biotreatment of aquatic sites polluted with heavy metal ions. Seaweeds have received great attention for their high bioremediation potential in recent years. However, the co-application of marine macroalgae for removal of heavy metals from wastewater is very limited. Thus, for the first time in literature, a coastal seaweed community composed of Chaetomorpha sp...

We present a theory of communal coping that describes an optimal pathway to patient adjustment among couples in which one person faces a chronic illness. Communal coping consists of a shared illness appraisal (i.e., person perceives illness as a joint rather than individual problem) and collaboration with a partner to manage the illness. We present a model of the communal coping process that links patient and partner shared illness appraisals to collaboration and a set of supportive interactions that might be reframed as collaboration in the presence of shared illness appraisals...

BACKGROUND: Nonsuicidal self-injury (NSSI) is common in adolescents and young adults, and few evidence-based treatments are available for this significant problem. N-acetylcysteine (NAC) is a widely available nutritional supplement that has been studied in some psychiatric disorders relevant to NSSI including mood and addictive disorders. This pilot study tested the use of NAC as a potential treatment for NSSI in youth. METHODS: Thirty-five female adolescents and young adults with NSSI aged 13-21 years were enrolled in this study that had an open-label, single-arm study design...

Structural quality and stability of nanocrystals are fundamental problems that bear important consequences for the performances of small-scale devices. Indeed, at the nanoscale, their functional properties are largely influenced by elastic strain and depend critically on the presence of crystal defects. It is thus of prime importance to be able to monitor, by noninvasive means, the stability of the microstructure of nano-objects against external stimuli such as mechanical load. Here we demonstrate the potential of Bragg coherent diffraction imaging for such measurements, by imaging in 3D the evolution of the microstructure of a nanocrystal exposed to in situ mechanical loading...

Smoking withdrawal negatively impacts inhibitory control, and these effects are greater for smokers with pre-existing attention problems, such as attention deficit/hyperactivity disorder (ADHD). The current study preliminarily evaluated changes in inhibitory control-related behavior and brain activation during smoking withdrawal among smokers with ADHD. Moreover, we investigated the role of catecholamine transmission in these changes by examining effects of 40 mg methylphenidate (MPH) administration. Adult daily smokers with (n=17) and without (n=20) ADHD completed fMRI scanning under each of three conditions: (a) smoking as usual+placebo; (b) 24 hr smoking abstinence+placebo and (c) 24 hr smoking abstinence+MPH...

Measures to identify infancy mental health problems are essential to guide interventions and reduce the risk of developmental psychopathology in early years. We investigated a new service-setting-based measure the Copenhagen Infant Mental Health Screening (CIMHS) within the general child health surveillance by community health nurses (CHN). The study population of 2973 infants was assessed by CIMHS at age 9-10 months. A subsample of 416 children was examined at age 1½ years, using parent interviews including the Child Behavior Checklist (CBCL 1½-5), Check List of Autism and Toddlers (CHAT), Infant-Toddler Symptom Checklist (ITSCL), and the Bayley Scales of Infant and Toddler Development (BSID) and observations of behavior, communication, and interaction...

Reward processing, which plays a critical role in adaptive behavior, is impaired in addiction disorders, which are accompanied by functional abnormalities in brain reward circuits. Internet gaming disorder, like substance addiction, is thought to be associated with impaired reward processing, but little is known about how it affects learning, especially when feedback is conveyed by less-salient motivational events. Here, using both monetary (±500 KRW) and symbolic (Chinese characters "right" or "wrong") rewards and penalties, we investigated whether behavioral performance and feedback-related neural responses are altered in Internet game overuse (IGO) group...

BACKGROUND AIMS: Retinal progenitor cells (RPCs) are a promising cell therapy treatment for retinal degenerative diseases. However, problems with limited proliferation ability and differentiation preference toward glia rather than neurons restrict the clinical application of these RPCs. The extracellular matrix (ECM) has been recognized to provide an appropriate microenvironment to support stem cell adhesion and direct cell behaviors, such as self-renewal and differentiation. METHODS: In this study, decellularized matrix of adipose-derived mesenchymal stromal cells (DMA) was manufactured using a chemical agent method (0...

Obesity has become a serious social problem in industrialized countries in recent years. Clinically, although the evaluation of dietary behavior abnormalities is as important as any method of risk assessment for obesity, almost all the existing scales with many items may have numerous practical clinical difficulties. In this study, we aimed to prepare a short questionnaire to assess the dietary behavior abnormalities related to obesity. A total of 1032 individuals aged 20 to 59 years participated in the present study...

Our previous studies showed that altering solely the drug experience of the cage mates with which rodents are housed affects the development of morphine dependence. In this study, we used designer receptors exclusively activated by designer drugs to artificially increase or decrease the activity of peripheral dorsal root ganglia sensory neurons expressing the G-protein-coupled receptor MRGPRB4. This is because sensory MRGPRB4-expressing neurons were shown to specifically detect the sensation of massage-like stroking resulting from social grooming, which is an important affiliative social behavior in the rodent...

Here, we present a MicroScale Thermophoresis (MST)-based assay for in vitro assessment of actin polymerization. By monitoring the thermophoretic behavior of ATTO488-labeled actin in a temperature gradient over time, we could follow polymerization in real time and resolve its three characteristic phases: nucleation, elongation, and steady-state equilibration. Titration experiments allowed us to evaluate the effects of actin-binding proteins (ABPs) on polymerization, including DNase I-induced inhibition and mDia2FH1FH2 (mDia2)-assisted acceleration of nucleation...

Indoor tanning remains a popular activity in Western cultures despite a growing body of literature suggesting its link to skin cancer and melanoma. Advances in indoor tanning research have illuminated problematic patterns of its use. With problems such as difficulty quitting, devoting resources toward its use at the expense of healthy activities, and excessive motivation and urges to tan, symptoms of excessive indoor tanning appear consistent with behavioral addiction. The present study bridges the gap between clinical approaches to understanding indoor tanning problems and behavioral economic considerations of unhealthy habits and addiction...

New unique and concise translation matrices are derived for evaluating the aberration variations of conceptual and real lenses when the paraxial marginal and chief ray paths are arbitrarily changed. They are helpful in investigating the general behaviors of lenses and optimizing the balanced aberrations of lens components in prime and zoom lenses. These new matrices, with a dimension of 9×9 for monochromatic aberrations and a dimension of 4×4 for chromatic aberrations, are derived based on our earlier algorithms of which four cases with distinct translation factors and matrices are required according to the relationships of the original and new positions of the object and pupil; otherwise, division-by-zero errors or insufficient numerical accuracy will be encountered...
