The present study investigated the effect of reused rubber particles (RRP) on the deicer salt durability of ordinary concrete. Four mixtures were designed, a control concrete (CC) and three other rubber concretes obtained by partial substitution of natural dune sand aggregate with reused rubber particles with 0%, 3%, 6%, and 9% w/w. All studied concretes were subjected to the combined effect of freeze/thaw (56 and 120) cycles with the deicer salt solution of 3% NaCl. The results indicated that RRP improved the deic [...]

he publication of the double helix DNA structure in 1953 [1] was the kick-off of numerous efforts to understand and unravel the complexity of the human genome. It took 50 years until the human genome project, based on Sanger sequencing, was completed in 2003 [2]. This was followed by what may be considered a revolution in the field of DNA analysis: the introduction of Next Generation Sequencing (NGS) in 2005 consisting of massively parallel sequencing of DNA fragments which allows the high throughput analysis of la [...]

Graft rejection, early allograft dysfunction (EAD), and poor diagnostic accuracy are some of the challenges that still need to be addressed, even though liver transplantation (LT) has the potential to help patients with end-stage liver disease (ESLD) significantly. Traditional procedures, such as liver biopsies and liver function tests (LFTs), often fail to identify abnormalities early and with accuracy. Genomic RNA sequencing (RNA-Seq) has recently emerged as a powerful approach for identifying molecular markers o [...]

Long COVID syndrome resulting from SARS-CoV-2 infection has a prevalence of 10%-35% in the population. Numerous studies of the disease are currently being conducted concerning the manifestations of long COVID syndrome; however, there are no data on the use of electroacupuncture diagnosis (EAV) and medicament testing (MT) in assessing this condition. The purpose of the study was to study the possibilities of diagnosing EAV to determine changes in the electrodermal activity of acupuncture points of the meridian test [...]

Air pollution affects various aspects of human health. Here, the associations between the number of emergency department visits for circulatory and respiratory problems and ambient air pollution in Toronto, Canada, in the period between April 2004 and December 2015 were studied. The health data were linked with urban air pollution data and weather factors. The conditional Poisson regression models were built for 18 strata (sex, age group, season), 8 exposure factors (air pollutants, indexes), and their 15 lags (0-1 [...]

This paper follows a preliminary study that examined how 6 (n = 6) creative arts therapists (3 art therapists and 3 drama therapists) coped with the transition to remote therapy in schools during the first lockdown in Israel due to the Coronavirus pandemic. The preliminary research explored the therapists’ experiences and views about working online upon returning to regular in-person meetings. The current paper adds a follow-up interview examining their perspective on this period, two years later. The 1st set of in [...]

Rett syndrome (RTT) is a rare neurodevelopmental disorder primarily affecting females, characterized by a spectrum of debilitating symptoms that impact neurological, cognitive, and motor functions. Eye-tracking technology (ETT) has emerged as a prominent tool in Augmentative and Alternative Communication (AAC) systems, particularly for neurological patients with motor and verbal impairments. This narrative review aimed to evaluate studies conducted on the use of ETT to improve cognitive abilities in girls with RTT [...]

Linear atomic chain (LAC) gold nanowires (Au-NWs) containing oxygen impurities are materials that could be used as supports to stimulate chemical reactions. Its peculiar structural characteristics, such as abnormal Au-Au bonds, make it interesting to explore the chemical reactions of this material at a theoretical level. This work investigated the chemical reaction of ethanol supported on Au-NW containing two oxygen impurities. Using ab initio molecular dynamics simulations, it was shown that the presence of oxygen [...]

"Case Studies in the Ethics of Assisted Reproduction" explores the moral and ethical implications of assisted reproductive technologies (ART), such as in vitro fertilization (IVF), surrogacy, and genetic screening. These findings outline ethical dilemmas, including the importance of informed consent, and highlight a multidisciplinary approach involving law, bioethics, reproductive endocrinology, and reproductive biology. Using case studies, the findings address ethical challenges in ART practice, such as the transf [...]

We aimed to assess some readily available patient characteristics such as urinary albumin excretion as predictors of a primary composite event of myocardial infarction, cerebral stroke, and cardiovascular death among patients with hypertension and left ventricular hypertrophy, and develop risk algorithms for the outcomes. A “Cox proportional hazards” model identified the baseline variables that significantly affected the occurrence of the composite endpoint in 9193 elderly hypertensive patients with lef [...]
