Left ventricular noncompaction cardiomyopathy (LVNC) is a rare form of heritable cardiomyopathy with wide genotypic variability, numerous phenotypic variations, and a wide spectrum of clinical disease from asymptomatic to end stage heart failure. Here, we present a case of a 2-year-old boy who presented to their pediatrician with a cough as a first clinical sign of heart failure, rapidly progressing to severe heart failure. He was found to have mixed LVNC with a restrictive phenotype, a rare phenotype of this form [...]

Recycled styrene butadiene rubber (rSBR) from waste car tires was used as a filler in poly(lactic) acid (PLA) to modify its properties. The compounds were prepared via twin-screw extrusion and molded by injection with different rSBR contents (0 to 25% wt.). Additionally, recycled rubber particle size was controlled between 125 and 1000 μm to determine the effect of this parameter. From the samples produced, a series of morphological, physical and mechanical characterizations were performed. As expected, rSBR additi [...]

In the U.S., older adults aged 65 or above comprise nearly one quarter of the solid organ transplant (SOT) waitlists, and the number of transplants performed in this age group continues to increase. There are no specific guidelines for the assessment and follow up of the older SOT candidate or recipient. Older adults are at increased risk of infectious complications after SOT. Despite these complications and even with the use of suboptimal donors, overall outcomes are favorable. We provide an overview to specific c [...]

This systematic review examines the role of SnRK2 (Sucrose non-fermenting 1-Related protein Kinase 2) genes in Arabidopsis thaliana growth and responses to abiotic stresses. SnRK2 protein kinases are key components of abscisic acid (ABA) signaling and osmotic stress responses in plants. The review synthesizes findings from numerous studies on how different SnRK2 genes regulate Arabidopsis growth, development, and stress tolerance at various life stages. Key topics covered include SnRK2 functions under environmental [...]

Background: All over the world we are confronted with an absolute and relative increase in the proportion of older people. In order to develop strategies to keep older people healthy and independent as long as possible, analyses of factors influencing health related quality of life (HRQL) during old age are necessary. The aim of this review is to present the results of three projects carried out in Austria by the author focusing on the impact of social contact and physical activity on HRQL. Methods: The standardize [...]

Background: Learning and memory, unquestionably, are critical for many aspects of life, including acquisition and retention of educational material. The purpose of this brief narrative review is to provide a primer on empirical-based, learning and memory techniques. Methods: A narrative review approach is employed. Results: This review is structured by first discussing contextual factors that influence learning and memory, followed by addressing several specific techniques to help facilitate learning and memory ret [...]

Outdoor school spaces are significant, as they provide great opportunities for outdoor exploration, leading to the overall enhancement of a student’s well-being. This paper analyzes the outdoor school spaces in Dubai to optimize them and ensure their thermal comfort. To achieve this aim, using a mixed methodology approach of survey, field observation, workshops and ENVI-met V5.3 software simulation, the existing outdoor spaces were analyzed and then enhanced using several proposed heat mitigation strategies. The im [...]

Neurons, from the time of their birth until their death, are always accompanied by neuroglial cells, maintaining very close morphological and functional relationships among themselves. Classically three main neuroglial families have been considered within the central nervous system (CNS): astroglia, oligodendroglia, and microglia. However, using morphological and immuno-cytochemical criteria, several different types/subtypes of neuroglial cells have been identified, each exerting specific physiological and patholog [...]

Background: Information and Communication Technologies (ICTs) have the potential to promote healthy aging and increase the quality of life of older adults. However, several barriers like access, performance, psychological, and privacy issues still exist against fully deploying ICT solutions for older adults. To determine useful methods to overcome such barriers, this work investigated the possible factors that prevent elders from directly accepting ICT services based on three field studies. Methods: The Unified The [...]

Magnetic resonance imaging (MRI) has been used to investigate migraine pathophysiology because it is a non-invasive technique. The main aim of clinical imaging for patients with headaches is to exclude secondary headaches due to organic lesions. Conventional structural imaging techniques such as routine MRI demonstrate white matter lesions, changes in gray matter volume or cortical thickness, and cerebral blood flow in patients with migraine. Changes in metabolite levels are observed by magnetic resonance spectrosc [...]
