Alcoholic liver diseases and virus-induced hepatic dysfunctions are prevalent in western countries. Evidence also suggests that hyperglycemia and insulin resistance are key players in the development of hepatic diseases and their complications. Since the comorbid diseases like obesity, diabetes and vascular dysfunctions primarily affect liver, the modern therapies against other hepatic dysfunctions are becoming a major challenge to treat. In addition to these, polypharmacy and adverse drug reactions (ADRs) are further aggravating the phenomenon...

OBJECTIVE: This study aimed to determine the association between overactive bladder (OAB), metabolic syndrome (MetS) and serum nerve growth factors (NGF). STUDY DESIGN: Serum samples from a group of 90 women that included patients with OAB (group 1), patients with both OAB and MetS (group 2) and healthy women without OAB and MetS (group 3). Each group included 30 patients. Serum levels of NGF were compared among the groups. RESULTS: When the groups were compared with respect to NGF levels, group 2 was found to have significantly higher NGF levels (p = 0...

BACKGROUND: Most people with severe mental illness (SMI) want to work. Individual placement and support (IPS) programs have proven effective in helping them obtain and keep competitive jobs. Yet, practitioners often fear that competitive jobs might be too stressful. AIMS: To explore how the nature and intensity of stress experienced by IPS clients changed after the transition from looking for work to being employed. METHODS: Semi-structured interviews explored the experiences of 16 clients of an IPS program who had recently been competitively employed...

Background and Objectives: Historically, research, practice, and policy on Alzheimer's family care has been largely focused on dyadic relationships and the experience of burden and stress, often failing to capture the complex caring dynamics as they unfold over time. This study sought to develop a more nuanced understanding of how people with Alzheimer's disease (AD) and their families are affected by the disease and how they respond to the challenges AD poses. Research Design and Methods: Using constructivist grounded theory, the study explored the experiences of living with AD for native Spanish families residing in Navarra...

BACKGROUND: Suicide rates among those employed in male-dominated professions such as construction are elevated compared to other occupational groups. Thus far, past research has been mainly quantitative and has been unable to identify the complex range of risk and protective factors that surround these suicides. METHODS: We used a national coronial database to qualitatively study work and non-work related influences on male suicide occurring in construction workers in Australia...

OBJECTIVES: Theories and research regarding cognitive and emotional processing during the experience of profound stressors suggest that the presence of intrusive thoughts and feelings predicts greater use of avoidance and that the use of avoidance paradoxically predicts more intrusions. However, empirical investigations of their purported bidirectional relationship are limited. DESIGN: This study presents a longitudinal investigation of the reciprocal relationship between intrusions and avoidance coping over a 6-month period in the year following breast cancer diagnosis...

Tunable spin transport in nano devices is highly desirable to spintronics. Here, we predict existence of quantum spin Hall effects and tunable spin transport in As-graphane, based on first-principle density functional theory and tight binding calculations. Monolayer As-graphane is constituted by using As adsorbing on graphane with honeycomb H vacancies. Owing to the surface strain, monolayer As-graphane nanoribbons will self-bend toward the graphane side. The naturally curved As-graphane nanoribbons then exhibit unique spin transport properties, distinctively different from the flat ones, which is a two-dimensional topological insulator...

Ecosystem engineers facilitate communities by providing a structural habitat that reduces abiotic stress or predation pressure for associated species. However, disturbance may damage or move the engineer to a more stressful environment, possibly increasing the importance of facilitation for associated communities. In this study we determined how disturbance to intertidal boulders (i. e. flipping) and the subsequent movement of a structural ecosystem engineer, the tube-forming serpulid worm Galeolaria caespitose, from the bottom (natural state, low abiotic stress) to the top (disturbed state, high abiotic stress) surface of boulders influenced the importance of facilitation for intertidal communities across two intertidal zones...

BACKGROUND: Economic transitions expose indigenous populations to a variety of ecological and cultural challenges, especially regarding diet and stress. These kinds of challenges are predicted by evolutionary ecological theory to have fitness consequences (differential reproduction) and, indeed, are often associated with changes in fertility dynamics. It is currently unclear whether international immigration might impact the nature of such an economic transition or its consequences for fertility...

The contact strength, adhesion and friction, between graphene and an incommensurate crystalline substrate such as h-BN depends on their relative alignment angle θ. The well-established Novaco-McTague (NM) theory predicts for a monolayer graphene on a hard bulk h-BN crystal face a small spontaneous misalignment, here θNM ≃ 0.45 degrees which if realized would be relevant to a host of electronic properties besides the mechanical ones. Because experimental equilibrium is hard to achieve, we inquire theoretically about alignment or misalignment by simulations based on dependable state-of-the-art interatomic force fields...

Based on the oxidative stress theory, aging derives from the accumulation of oxidized proteins induced by reactive oxygen species (ROS) in the cytoplasm. Hydrogen peroxide (H2O2) elicits ROS that induces skin aging through oxidation of proteins, forming disulfide bridges with cysteine or methionine sulfhydryl groups. Decreased Ca(2+) signaling is observed in aged cells, probably secondary to the formation of disulfide bonds among Ca(2+) signaling-related proteins. Skin aging processes are modeled by treating keratinocytes with H2O2...

OBJECTIVES: Interpersonal trauma has deleterious effects on mental health (1) , with college students experiencing relatively high rates of lifetime trauma (2) . Asian American/Pacific Islanders (AAPIs) have the lowest rate of mental health care utilization (4) . According to cultural betrayal trauma theory (CBTT) (9, 10, 11) , societal inequality may impact within-group violence in minority populations, thus having implications for mental health. In the current exploratory study, between-group (interracial) and within-group (ethno-cultural betrayal) trauma and mental health outcomes were examined in AAPI college students...

Poly(butylene adipate-co-terephthalate) (PBAT) was first chemically modified via free radical grafting with maleic anhydride (MA) and the MA-g-PBAT graft copolymer was then used as a matrix material to obtain cellulose nanocrystal (CNC)-reinforced MA-g-PBAT bio-nanocomposites via reactive extrusion process to accelerate efforts to develop functional bioabsorbable polymer nanocomposites with improved properties. The molecular structure of the PBAT after chemical modification with maleic anhydride was confirmed by 1H NMR and FTIR spectroscopy...

REVIEW
Preecha Yingwattanakul, George P Moschis
Preventive healthcare is considered a cornerstone of good health and well-being that can play a major role in reducing a country's healthcare costs and improving both the length and quality of people's lives. Previous research on preventive healthcare behaviors has been predominantly cross-sectional, ignoring the dynamic nature of people's health behaviors over a full life span. As a result, the reasons for the development, stability, and changes of individuals' preventive healthcare behaviors over time remain relatively unknown...

BACKGROUND: This article reports three studies describing the development and validation of the 12-item Sensitivity to Pain Traumatization Scale (SPTS-12). SPT refers to the anxiety-related cognitive, emotional, and behavioral reactions to pain that resemble the features of a traumatic stress reaction. METHODS: In Study 1, a preliminary set of 79 items was administered to 116 participants. The data were analyzed by using combined nonparametric and parametric item response theory resulting in a 12-item scale with a one-factor structure and good preliminary psychometric properties...

Evolutionary theory of ageing maintains that increased allocation to early-life reproduction results in reduced somatic maintenance, which is predicted to compromise longevity and late-life reproduction. This prediction has been challenged by the discovery of long-lived mutants with no loss of fecundity. The first such long-lived mutant was found in the nematode worm Caenorhabditis elegans Specifically, partial loss-of-function mutation in the age-1 gene, involved in the nutrient-sensing insulin/insulin-like growth factor signalling pathway, confers longevity, as well as increased resistance to pathogens and to temperature stress without appreciable fitness detriment...

In C. elegans, the skn-1 gene encodes a transcription factor that resembles mammalian Nrf2 and activates a detoxification response. skn-1 promotes resistance to oxidative stress (Oxr) and also increases lifespan, and it has been suggested that the former causes the latter, consistent with the theory that oxidative damage causes aging. Here, we report that effects of SKN-1 on Oxr and longevity can be dissociated. We also establish that skn-1 expression can be activated by the DAF-16/FoxO transcription factor, another central regulator of growth, metabolism, and aging...

REVIEW
Florian Kurth, Nicolas Cherbuin, Eileen Luders
Over the last decade, an increasing number of studies has reported a positive impact of meditation on cerebral aging. However, the underlying mechanisms for these seemingly brain-protecting effects are not well-understood. This may be due to the fact, at least partly, that systematic empirical meditation research has emerged only recently as a field of scientific scrutiny. Thus, on the one hand, critical questions remain largely unanswered; and on the other hand, outcomes of existing research require better integration to build a more comprehensive and holistic picture...
