The structural and electronic properties of germanene are always strongly modulated by the hybridization effects with metal substrates. In order to see what will happen when a buffer layer is introduced in-between germanene and metal substrates, we study the structural and electronic properties of the recently synthesized monolayer and bilayer germanene on Cu(111) though first-principles calculations. Our results show that the monolayer germanene on Cu(111) displays a nearly flat configuration and interface states form between the Ge pz and Cu sp-like states, with the Ge π states maintaining the Dirac character...

Heart failure is a prevalent, progressive chronic disease costing in excess of $1billion per year in Australia alone. Disease self-management has positive implications for the patient and decreases healthcare usage. However, adherence to recommended guidelines is challenging and existing literature reports sub-optimal adherence. mHealth applications in chronic disease education have the potential to facilitate patient enablement for disease self-management. To the best of our knowledge no heart failure self-management application is available for safe use by our patients...

BACKGROUND: Mothers of infants with complex congenital heart disease are exposed to increased stress which has been associated with numerous adverse health outcomes. The coping mechanisms these mothers use critically effect the familial illness adaptation and most likely infant outcomes. Currently no data-based strategies have been developed for mothers to facilitate their coping, and proactively promote their adaptation in the critical care settings. A potential strategy is mindfulness which is currently used in other clinical settings with stress-reduction effects...

Microparticles (MPs) are cell-cell communication vesicles derived from the cell surface plasma membrane, although they are not known to originate from cardiac ventricular muscle. In ventricular cardiomyocytes, the membrane deformation protein cardiac bridging integrator 1 (cBIN1 or BIN1+13+17) creates transverse-tubule (t-tubule) membrane microfolds, which facilitate ion channel trafficking and modulate local ionic concentrations. The microfold- generated microdomains continuously reorganize, adapting in response to stress to modulate the calcium signaling apparatus...

The US Preventive Services Task Force (USPSTF) Draft Recommendation statement on Menopausal Hormone Therapy: Primary Prevention for Chronic Diseases, released in May 2017, perpetuates a major disconnect between the primary population affected, women within roughly 10 years of menopause, and the data cited. Furthermore, major elements of the evidence relied upon have been misinterpreted or misstated, particularly in regard to coronary heart disease and breast cancer, for which there is no statistically significant evidence of harm...

RATIONALE: Peripheral immune responses can be modified by associative learning procedures. Less is known, however, whether and to what extent neuroendocrine parameters can be classically conditioned. OBJECTIVES: In this randomized double-blind study, we modified an established paradigm to behaviorally condition endocrine responses in humans. METHODS: Thirty-one healthy male participants received a distinctively flavored green drink as the conditioned stimulus (CS) and intravenous injections of corticotropin-releasing hormone (CRH) (CRH group, N = 17) or NaCl (placebo group, N = 14) as the unconditioned stimulus (US) during two subsequent acquisition trials...

The major issue in coronary heart disease (CHD) diagnosis and management is that symptoms onset in an advanced state of disease. Despite the availability of several clinical risk scores, the prediction of cardiovascular events is lacking, and many patients at risk are not well stratified according to the canonical risk factors alone. Therefore, adequate risk assessment remains the most challenging issue. Recently, the integration of imaging data with biochemical markers in a radiogenomic framework has been proposed in many fields of medicine as well as in cardiology...

Development of unconventional technologies for wireless collection, storage and analysis of quantitative, clinically relevant information on physiological status is of growing interest. Soft, biocompatible systems are widely regarded as important because they facilitate mounting on external (e.g. skin) and internal (e.g. heart, brain) surfaces of the body. Ultra-miniaturized, lightweight and battery-free devices have the potential to establish complementary options in bio-integration, where chronic interfaces (i...

The National Heart Lung and Blood Institute is funding an effort to create a molecular atlas of the developing lung (LungMAP) to serve as a research resource and public education tool. The lung is a complex organ with lengthy development time driven by interactive gene networks and dynamic crosstalk among multiple cell types to control and coordinate lineage specification, cell proliferation, differentiation, migration, morphogenesis and injury repair. A better understanding of the processes that regulate lung development, particularly alveologenesis, will have significant impact on survival rates for premature infants born with incomplete lung development and will facilitate lung injury repair and regeneration in adults...

Limb-girdle muscular dystrophy types 2D and 2F (LGMD 2D and 2F) are autosomal recessive disorders caused by mutations in the alpha- and delta sarcoglycan genes, respectively, leading to severe muscle weakness and degeneration. The cause of the disease has been well characterized and a number of animal models are available for pre-clinical studies to test potential therapeutic interventions. To facilitate transition from drug discovery to clinical trials, standardized procedures and natural disease history data were collected for these mouse models...

The direct reprogramming of cardiac fibroblasts into induced cardiomyocyte (CM)-like cells (iCMs) holds great promise in restoring heart function. We previously found that human fibroblasts could be reprogrammed toward CM-like cells by 7 reprogramming factors; however, iCM reprogramming in human fibroblasts is both more difficult and more time-intensive than that in mouse cells. In this study, we investigated if additional reprogramming factors could quantitatively and/or qualitatively improve 7-factor-mediated human iCM reprogramming by single-cell quantitative PCR...

Diabetic cardiomyopathy (DCM) is a serious complication of diabetes. Hydrogen sulphide (H2S), a newly found gaseous signalling molecule, has an important role in many regulatory functions. The purpose of this study is to investigate the effects of exogenous H2S on autophagy and its possible mechanism in DCM induced by type II diabetes (T2DCM). In this study, we found that sodium hydrosulphide (NaHS) attenuated the augment in left ventricular (LV) mass and increased LV volume, decreased reactive oxygen species (ROS) production and ameliorated H2S production in the hearts of db/db mice...

We speculated that ubiquitin specific peptidase 4 (USP4) may deubiquitinate interferon regulatory factor 4 (IRF4) and affect T helper type 2 (Th2) cell function. This study aimed to validate this hypothesis. Here, the interaction between USP4 and IRF4 were analyzed by co-immunoprecipitation assay. The deubiquitin effect of USP4 on IRF4 was analyzed by the Ni-NTA pull down assay. Luciferase reporter gene constructs were used to analyze the effects of USP4, IRF4 and nuclear factor of activated T cell-2 (NFATc2) on the activation of the interleukin-4 (IL-4) promoter...

Despite improving survival rates for pediatric cardiac arrest victims, they remain strikingly low. Evidence for pediatric cardiopulmonary resuscitation is limited with many areas of ongoing controversy. The American Heart Association provides updated guidelines for life support based on comprehensive reviews of evidence-based recommendations and expert opinions. This facilitates the translation of scientific discoveries into daily patient care, and familiarization with these guidelines by health care providers and educators will facilitate the widespread, consistent, and effective care for patients...
