REVIEW
Dong Woo Kang, Chang Uk Lee, Hyun Kook Lim
Sleep disturbances such as insomnia, hypersomnia, and circadian rhythm disturbance are common in normal elderly and Alzheimer's disease (AD) patients. To date, special attention has been paid to sleep disturbance in the clinical course of AD insofar as the interaction of sleep disturbance with the pathogenesis of AD may impact the clinical course and cognitive function of AD patients. This review covers the bidirectional relationship between sleep disturbance and AD pathogenesis; the associations between sleep disturbance and AD-specific neurotransmitters, brain structure, and aspects of sleep disturbance in each phase of AD; and the effects of sleep disturbance on the cognitive functions of patients in each phase of AD...

OBJECTIVES: Central sensitization (CS) implies increased sensitivity of the nervous system, resulting in increased pain sensitivity as well as widespread pain. Recently, the Central Sensitization Inventory (CSI) was developed to assess symptoms of CS and central sensitivity syndromes. The aim of this study was to examine the convergent validity of the CSI by comparing the outcome to psychosocial factors and clinical features of CS. METHODS: In a cross-sectional explorative study, patients with chronic pain completed multiple questionnaires, including the CSI, pain catastrophizing scale, SCL-90 for psychological distress, duration of pain, intensity of pain, widespread pain, and lateralization of pain...

The use of psychostimulants, such as amphetamine (Amph), is associated with inflammatory processes, involving glia and vasculature alterations. Brain Angiotensin II (Ang II), through AT1 -receptors (AT1 -R), modulates neurotransmission and plays a crucial role in inflammatory responses in brain vasculature and glia. Our aim for the present work was to evaluate the role of AT1 -R in long-term alterations induced by repeated exposure to Amph. Astrocyte reactivity, neuronal survival and brain microvascular network were analyzed at the somatosensory cortex...

The Strengths and Difficulties Questionnaire (SDQ), routinely used to screen for children's and adolescents' emotional and behavioural problems, has been translated into at least 80 languages. As children of refugee background are particularly vulnerable to mental health problems resulting from their refugee experiences, this review examines whether SDQs translated into languages spoken by major refugee groups are validated and culturally equivalent to the original SDQ and sensitive to change following interventions...

We report on the psychometric properties of the Mental Health and Social Inadaptation Assessment for Adolescents (MIA), a self-report instrument for quantifying the frequency of mental health and psychosocial adaptation problems using a dimensional approach and based on the DSM-5. The instrument includes 113 questions, takes 20-25 minutes to answer, and covers the past 12 months. A population-based cohort of adolescents (n = 1443, age = 15 years; 48% males) rated the frequency at which they experienced symptoms of Attention Deficit Hyperactivity Disorder (ADHD), Conduct Disorder, Oppositional Defiant Disorder, Depression, Generalized Anxiety, Social Phobia, Eating Disorders (i...

Carbohydrate structures on the cell surface encode complex information that through specific recognition by carbohydrate-binding proteins (lectins), modulates interactions between cells, cells and the extracellular matrix, or mediates recognition of potential microbial pathogens. Galectins are a family of ß-galactoside-binding lectins, which are evolutionary conserved and have been identified in most organisms, from fungi to invertebrates and vertebrates, including mammals. Since their discovery in the 1970s, their biological roles, initially understood as limited to recognition of endogenous carbohydrate ligands in embryogenesis and development, have expanded in recent years by the discovery of their roles in tissue repair and regulation of immune homeostasis...

Parental break-up is wide spread, and the effects of parental break-up on children's well-being are known. The evidence regarding child age at break-up and subsequent family arrangements is inconclusive. Aim: to estimate the effects of parental break-up on stress in pre-adolescent children with a specific focus on age at break-up and post-breakup family arrangements. We used data from the Danish National Birth Cohort. Participants included 44 509 children followed from birth to age 11. Stress was self-reported by children at age 11, when the children also reported on parental break-up and post break-up family arrangements...

Adenovirus (AdV) morphogenesis is a complex process, many aspects of which remain unclear. In particular, it is not settled where in the nucleus assembly and packaging occur, and whether these processes occur in a sequential or a concerted manner. Here we use immunofluorescence and immunoelectron microscopy (immunoEM) to trace packaging factors and structural proteins at late times post infection by either wildtype virus or a delayed packaging mutant. We show that representatives of all assembly factors are present in the previously recognized peripheral replicative zone, which therefore is the AdV assembly factory...

During 2003-2013, fatality rates for oil and gas extraction workers decreased for all causes of death except those associated with fall events, which increased 2% annually during 2003-2013 (1). To better understand risk factors for these events, CDC examined fatal fall events in the oil and gas extraction industry during 2005-2014 using data from case investigations conducted by the Occupational Safety and Health Administration (OSHA). Sixty-three fatal falls were identified, accounting for 15% of all fatal events...

BACKGROUND: Cardiovascular diseases are the main cause of death in most countries and the past two decades have shown a global increase. Hypertension (HTN) was found to be the leading risk factor in 2010 as qualified by Disability Adjusted Life Years. Epidemiological studies in this regard in Sri Lanka are scarce. Thus, describing epidemiological patterns of HTN in the Sri Lankan population will help policy makers in planning preventive healthcare programs and aid in preparing strategies to cope with the increasing demand for healthcare facilities...

Junction of Ag(In, Ga)Se2 (AIGS)/Mo and Cu(In, Ga)Se2 (CIGS)/Mo were characterized and compared from the prospect of structural and electrical properties. The region between CIGS and Mo was filled by a layered hexagonal MoSe2 layer with a thickness of 10-15 nm. The c-axis of MoSe2 was mostly perpendicular with the Mo layer, while the c value was 12.6 Å. However, no such layer was observed at the interface of AIGS and Mo. The result was also confirmed by the energy dispersive x-ray spectrometer and x-ray diffraction pattern to confirm status of MoSe2 layer...

Inhalation of allergens and pathogens elicits multiple changes in a variety of immune cell types in the lung. Flow cytometry is a powerful technique for quantitative analysis of cell surface proteins on immune cells, but it provides no information on the localization and migration patterns of these cells within the lung. Similarly, chemotaxis assays can be performed to study the potential of cells to respond to chemotactic factors in vitro, but these assays do not reproduce the complex environment of the intact lung...

Hongcheng Liu, Peng Dong, Lei Xing
Traditional inverse planning relies on the use of weighting factors to balance the conflicting requirements of different structures. The manual trial-and-error determination of the weighting factors has long been recognized as a time-consuming part of treatment planning. The purpose of this work is to develop an inverse planning framework that parameterizes the dosimetric tradeoff among the structures with physically meaningful quantities to simplify the search for clinically sensible plans. In this formalism, instead of using the weighting factors, permissible variation range of the prescription dose or dose volume histogram (DVH) of the involved structures are used to characterize the "importance" of the structures...

Conscientiousness is a fundamental aspect of human personality, one that is closely linked with various favorable life outcomes. Despite its importance in humans, conscientiousness has received little attention as to how it may have evolved, or whether it provides similar fitness benefits in other animals. To date, research in animal personality has found consistent support for the presence of all major dimensions of human personality in other animals except conscientiousness. In this review, we investigate conscientiousness at the level of traits and facets (clusters of closely related traits)...

Theoretical and experimental studies on resonant magnetic scattering have been carried out using circularly polarized X-rays. Polarization dependence of the asymmetric ratio between right- and left-handed polarized scattering amplitudes has revealed that resonant and non-resonant magnetic scatterings can be observed simultaneously. In this study, synchrotron X-ray intensity experiments were conducted on Gd iron garnet (GdIG) at the pre-edge of the Fe K absorption edge. The asymmetric ratio between circular polarizations exhibited three peaks due to the resonant magnetic responses of Fe(3+) in the Fe2 (24d) site...

This study clarifies why, in the phantom derivative (PhD) approach, randomly created structures can help in refining phases obtained by other methods. For this purpose the joint probability distribution of target, model, ancil and phantom derivative structure factors and its conditional distributions have been studied. Since PhD may use n phantom derivatives, with n ≥ 1, a more general distribution taking into account all the ancil and derivative structure factors has been considered, from which the conditional distribution of the target phase has been derived...
