Mechanisms of action in the relationship between mindfulness and problem gambling behaviour

Previous studies have found an inverse relationship between mindfulness and problem gambling severity. This paper presents the findings from two studies of treatment seeking problem gamblers designed to explore the role of mindfulness in problem gambling. Treatment-seeking problem gamblers displayed significantly lower mindfulness scores than adult community members and university students. Mindfulness was significantly related to most indices of gambling, and psychological distress was an important mechanism in these relationships. Rumination, emotion dysregulation and thought suppression were also implicated as mediators in the inverse relationship between mindfulness and psychological distress. Taken together, the findings provide theoretical support for existing models of mindfulness which suggest that mindfulness operates by reducing psychological distress through these cognitive mechanisms. They also suggest that mindfulness training may be a new and innovative avenue for therapy to improve treatment effectiveness for problem

The mechanisms of Chansu in inducing efficient apoptosis in colon cancer cells

Chansu is one of the most widely used traditional Chinese medicines in China, Japan, and other Southeast Asian countries primarily for antipain, anti-inflammation, and recently anticancer. Over 10 recipes and remedies contained Chansu, which are easily available in pharmacies and hospitals, but the mechanisms of action were not clearly articulated. In the present study, Cinobufagin (CBF), the major compound of Chansu, was employed as a surrogate marker to determine its ability in inducing cancer cell death. As expected, CBF has significant cancer-killing capacity for a range of cancers, but such ability differs markedly. Colon and prostate cancers are more sensitive than skin and lung cancers. Interestingly, cancer cells die through apoptotic pathway either being biphasic caspase- 3-dependent (HCT116) or independent (HT29). Multipathway analysis reveals that CBF-induced apoptosis is likely modulated by the hypoxia-inducing factor-1 alpha subunit (HIF-1

Myopia : why study the mechanisms of myopia? Novel approaches to risk factors Signaling eye growth- how could basic biology be translated into clinical insights? Where are genetic and proteomic approaches leading? How does visual function contribute to an

On July 26–29, 2010 the 13th International Myopia Conference was held in Tübingen, Germany and included 17 separate symposia, each with 3–5 presentations. Here, in a single paper, the chairs of those Symposia describe the scientific advances noted at the conference and include the full abstracts of the individual myopia papers presented in each symposium along with the authors and their institutions. The 17 Symposia covered 7 topics: Why Study the Mechanisms of Myopia?; Novel Approaches to Risk Factors; Signaling Eye Growth- How Could Basic Biology Be Translated into Clinical Insights?; Where Are Genetic and Proteomic Approaches Leading?; How Does Visual Function Contribute to and Interact with Ametropia?; Does Eye Shape Matter?; Why Ametropia at All?

Investigation of corrosion inhibition mechanisms of rare-earth mercaptoacetate inhibitors on AA2024-T3

 Corrosion inhibition mechanisms on the aerospace alloy, AA2024-T3, was investigated for the inhibitor combination of rare earth metals and mercaptoacetate. The inhibitor demonstrated synergistic protection for AA2024-T3 from localised corrosion. It is intended to be a more environmentally friendly alternative to toxic chromate-based inhibitors.

Diet and bipolar disorder: a review of its relationship and potential therapeutic mechanisms of action

OBJECTIVES: It is well accepted that diet quality has an important role in the prevention and treatment of several physical diseases. However, its influence on mental health has received far less attention, although there is increasing evidence to support a relationship with depression. In this narrative review, investigations into the relationship between diet and bipolar disorder are examined and the potential implications in the management and treatment of bipolar disorder are reviewed. METHODS: The authors provide a narrative review of the relevant information. RESULTS: Research is limited, although there are preliminary findings to suggest a relationship between diet and bipolar disorder. Findings from cross-sectional research suggest that people with bipolar disorder consume an unhealthier dietary pattern. This has significant treatment implications as bipolar disorder has a high comorbidity with several physical diseases. In addition, diet also influences several biological processes that are dysregulated in bipolar disorder, namely monoaminergic activity, immune/inflammatory processes, oxidative stress, mitochondrial activity, and neuroprogression. CONCLUSIONS: The role of diet in bipolar disorder requires further attention in research as it presents as a factor that may contribute to the worsening course of this condition and may potentially enhance current treatment outcomes.

Mechanisms of anxiety related attentional biases in children with Autism Spectrum Disorder

Children with autism spectrum disorder (ASD) have high levels of anxiety. It is unclear whether they exhibit threat-related attentional biases commensurate with anxiety disorders as manifest in non-ASD populations, such as facilitated attention toward, and difficulties disengaging engaging from, threatening stimuli. Ninety children, 45 cognitively able with ASD and 45 age, perceptual-IQ, and gender matched typically developing children, aged 7–12 years, were administered a visual dot probe task using threatening facial pictures. Parent-reported anxiety symptoms were also collected. Children with ASD showed similarly high levels of anxiety compared with normative data from an anxiety disordered sample. Children with ASD had higher levels of parent-reported anxiety but did not show differences in disengaging from, or facilitated attention toward, threatening facial stimuli compared with typically developing children. In contrast to previously published studies of anxious children, in this study there were no differences in attentional biases in children with ASD meeting clinical cutoff for anxiety and those who did not. There were no correlations between attentional biases and anxiety symptoms and no gender differences. These findings indicate the cognitive mechanisms underlying anxiety in cognitively able children with ASD could differ from those commonly found in anxious children which may have implications for both understanding the aetiology of anxiety in ASD and for anxiety interventions

How does microfinance enhance entrepreneurial outcomes in emerging economies? The mediating mechanisms of psychological and social capital

In this article, a conceptual framework and research propositions are developed to explain how microfinance provision can translate into new venture creation and existing venture growth in an emerging economy context by engendering higher levels of psychological and social capital in clients. In doing this, the extent to which microfinance institutions provide business support and opportunities for social interaction are identified as factors which may strengthen the impact of microfinance provision on psychological and social capital, especially for poor entrepreneurs in resource-constrained settings. The conceptual framework and research propositions developed will be of use to academics in designing an agenda for future empirical research. In addition, they will help policymakers and microfinance providers to better design microfinance initiatives that enhance the well-being of clients and maximise their entrepreneurial outcomes. © The Author(s) 2013.
