EXPLORING 35-44 YEAR OLD MEN’S HEALTH BEHAVIOUR: A QUALITATIVE PERSPECTIVE

2017

Upon reaching 35-44 year of age, men experience their first health problems, often because of an unhealthy way of life e.g., smoking, physical inactivity, unhealthy nutrition habits, etc. In comparison with other age groups, these men rarely look for medical help, thus, opening themselves up to a number of potentially negative consequences e.g. health risks in future. This study explores the health behaviour of 35-44 year old men by conducting semi-structured in-depth interviews with 48 participants. The data are further analysed using inductive thematic analysis. Results indicate the presence of three main types of men’s behaviour: 1) participants with positive attitude towards one’s healt…

Demographics, Socioeconomic Status, Social Distancing, Psychosocial Factors and Psychological Well-Being among Undergraduate Students during the COVI…

2021

The COVID-19 pandemic impacted on academic routine because of the social distancing measures. This study examined the relationships of sociodemographic characteristics, social distancing aspects and psychosocial factors on psychosocial well-being among undergraduate students during the social distancing period due to COVID-19. A web-based survey was conducted of undergraduate students at a public university in Brazil (n = 620). Demographics, socioeconomic status (SES), social distancing factors, negative affectivity (DASS-21), sense of coherence (SOC-13), social support and psychosocial well-being (GHQ-12) were measured. The direct and indirect links between was variables was tested using s…

Soluble ST2 and Diuretic Efficiency in Acute Heart Failure and Concomitant Renal Dysfunction

2021

Abstract Background Identifying patients at risk of poor diuretic response in acute heart failure (AHF) is critical to make prompt adjustments in therapy. The objective of this study was to investigate whether the circulating levels of soluble ST2 predict the cumulative diuretic efficiency (DE) at 24 and 72 hours in patients with AHF and concomitant renal dysfunction. Methods and Results This is a post hoc analysis of the IMPROVE-HF trial, in which we enrolled 160 patients with AHF and renal dysfunction (estimated glomerular filtrate rate of Conclusions In patients with AHF and renal dysfunction at presentation, circulating levels of sST2 were independently and negatively associated with a …

Impeded Dark Matter

2016

We consider dark matter models in which the mass splitting between the dark matter particles and their annihilation products is tiny. Compared to the previously proposed Forbidden Dark Matter scenario, the mass splittings we consider are much smaller, and are allowed to be either positive or negative. To emphasize this modification, we dub our scenario "Impeded Dark Matter". We demonstrate that Impeded Dark Matter can be easily realized without requiring tuning of model parameters. For negative mass splitting, we demonstrate that the annihilation cross-section for Impeded Dark Matter depends linearly on the dark matter velocity or may even be kinematically forbidden, making this scenario al…

Estimation of power supply harmonic impedance using a controlled voltage disturbance

2002

A novel method for power system impedance estimation is presented. The method employs a power converter to inject a voltage transient onto the supply system. The impedance is estimated through correlation of the measured voltage and current transients. Simulations and experimental results demonstrate the effectiveness of this measurement technique.

The chaperone system in cancer therapies: Hsp90

2023

AbstractThe chaperone system (CS) of an organism is composed of molecular chaperones, chaperone co-factors, co-chaperones, and chaperone receptors and interactors. It is present throughout the body but with distinctive features for each cell and tissue type. Previous studies pertaining to the CS of the salivary glands have determined the quantitative and distribution patterns for several members, the chaperones, in normal and diseased glands, focusing on tumors. Chaperones are cytoprotective, but can also be etiopathogenic agents causing diseases, the chaperonopathies. Some chaperones such as Hsp90 potentiate tumor growth, proliferation, and metastasization. Quantitative data available on t…

Local structure of perovskites ReO3and ScF3with negative thermal expansion: interpretation beyond the quasiharmonic approximation

2016

We propose an approach beyond the quasiharmonic approximation for interpretation of EXAFS and XRD data and for ab initio calculations of electronic and vibration properties of materials with negative thermal expansion. Ab initio electronic structure and lattice dynamics calculations for cubic and distorted ScF3 were performed using the linear combination of atomic orbitals (LCAO) method. The band gap obtained in calculations for ScF3 is equal to 10.54 eV and agree well with the expected value. The calculated infrared spectra of F displaced (FD) cubic ScF3 allow us to predict that its mean Sc-F-Sc angle within NTE deviates from 180 degree.

Ab initio molecular dynamics simulations of the Sc K-edge EXAFS of scandium trifluoride

2016

Scandium fluoride ScF3 has a simple cubic structure and attracts attention due to its large negative thermal expansion (NTE) over a wide range of temperatures (0-1100 K). In this study we present ab initio molecular dynamics (AIMD) simulations of ScF3 and their validation using the Sc K-edge EXAFS spectra in the temperature range from 300 K to 1000 K measured at the XAFS beamline of ELETTRA. The obtained results allow an assessement of the employed AIMD model and provide insight into the local structure and the lattice dynamics of ScF3 beyond the harmonic approximation. A strong anisotropy of the fluorine atom vibrations in the direction orthogonal to the -Sc-F-Sc- chain is observed. An exp…

Consumers’ Perception and Behavior Towards Ecosanogene Products Made by Goat Milk

2014

Abstract This study was conducted in Sibiu, Romania to examine consumers ‘ratings of healthy products made by goat milk and health issues. It has been also examine the sociodemographic factors and the relations between food safety and human welfare. This study is based on a questionnaire, interviewing a target group consists of 105 people. The purpose of this poll was to understand the consumer needs and how the quality of the brand influences purchasing choice. The instrument used for data processing was ANOVA Regression. The results can reveal that the selected model is valid for respondents who ticked test positive, P-value = 1.31E-26 <0.05; for negative response (option “b), P-value …
