This paper studies and characterizes a solar collector with spherical geometry to produce hot water for sanitary and domestic applications and other facilities. The new geometry enlarges the solar collector surface and allows full sun tracking during the day without needing a solar tracking system. Although this geometry has been in use for some time, its market penetration is low due to the lack of perfect knowledge of solar collector behavior and the benefits compared with conventional solar collectors. The studi [...]

In this study, we found that adding catalytic cracking feedstock, vacuum gas oil, and naphthenic acids in the amount of 0.005–0.0075% vol. increased the liquid target fractions, i.e., gasoline and light gas oil. The decrease in the yield of hydrocarbon gas at a practically constant degree of conversion of the raw material indicated a small proportion of the reactions of re-cracking of the resulting products. This also indicated the resource-saving nature of the process, allowing a larger amount of gasoline fraction [...]

Many health systems have joined the Age-Friendly Health Systems movement to provide every older adult safe, high-quality care aligned with what matters most. Becoming an Age-Friendly Health System means that hospitals and health care systems reliably use a set of evidence-based practices known as the “4M’s” – What Matters, Medication, Mentation, and Mobility – to provide care for older, disabled and medically complex patients across all care settings. Implementing the Institute for Healthcare Improvement’s (IHI) 4M [...]

Epilepsy, a prevalent neurological disorder, affects more than 50 million individuals worldwide and is characterized by recurring seizures. Nonsynonymous single nucleotide polymorphisms (nsSNPs) found within coding regions of epilepsy-related genes are believed to have significant impacts on protein function. This is due to their tendency to cause mutations in the encoded amino acids, which can subsequently lead to pathogenic alterations in protein structure and function. Consequently, nsSNPs have the potential to [...]

Technology makes it possible to expand many of the current screening programs. Initiatives for preconception screening of carrier status of recessive diseases, prenatal screening of aneuploidies and neonatal screening were initially undertaken by targeting one or at most, a few, conditions. Tandem mass spectrometry and genomic technologies, such as sequencing and panel testing, make it possible to increase the scope of these programs to include more disorders or markers. While inclusion of a larger number of condit [...]

This study reviews the biochemical mechanisms and clinical implications of N-heterocyclic amine drugs, particularly in the context of pain management, mental health, and opioid withdrawal. It highlights the structural diversity and receptor binding capabilities of these compounds, which enable them to target the nervous system and cross the blood-brain barrier effectively. The article discusses the role of opioids in pain relief, detailing their agonistic effects on opioid receptors and the subsequent risk of addic [...]

Fusarium is the most common soil-borne pathogen that causes wilt in many plant crops, among which the tomato is one of the most susceptible crops. This experiment is conducted to analyse the impacts of inorganic carbon compounds i.e., calcium carbonate CaCO3, sodium carbonate Na2CO3 and potassium bicarbonate KHCO3 on the growth of Fusarium oxysporum f. sp. lycopersici (FOL) causing wilt in tomato plant in different culture media including Malt Extract Agar (MEA), Potato Dextrose Agar (PDA) and V8. Three concentrati [...]

The current study aimed to investigate the effect of a multi-species probiotic (MSP) on cytokine production by human peripheral blood mononuclear cells (PBMCs) and their immune dialogue with HT-29 colon cancer cells. PBMCs were incubated with MSP and their effect on cell proliferation and TNFα, IL-1β, IL-2, IL-6, IFNγ, IL-10, and IL-1ra production was evaluated. The impact of MSP on the cytokine production by PBMC stimulated by HT-29 cells was detected. Not-stimulated PBMC incubated with MSP showed increased produc [...]
