Nearly 40 years of aerosol optical thickness (AOT) climate data record (CDR) from AVHRR satellite observations over the global ocean is used to study the impact of COVID-19 lockdowns and Australian bushfires on aerosol loading over downwind oceanic regions. Recent similar impact studies, by contrast, were mainly focused on the urban and suburban areas near the emission sources. AOT is used as a proxy for aerosol loading in our study. We found that AOT variations due to anthropogenic emission reduction during the lo [...]

The TiO2/MCM-41 nanomaterials were synthesized by impregnation with an excess solvent with different percentages of titanium dioxide. They were used for catalytic degradation of Benzene Toluene Ethylbenzene and Xylenes (BTEX) in the presence of hydrogen peroxide in aqueous media. The obtained materials were characterized by X-ray Diffraction, nitrogen adsorption-desorption using the BET method and Fourier Transform Infrared Spectroscopy. The nanostructured phase of the hexagonal ordered materials was obtained even [...]

“Epigenetics is the study of how your behaviors and environment can cause changes that affect the way your genes work. Unlike genetic changes, epigenetic changes are reversible and do not change your DNA sequence, but they can change how your body reads a DNA sequence” (https://www.cdc.gov/genomics/disease/epigenetics.htm). Epigenetic interactions, along with the genetic expression in innate cells, change the structure and function of chromatin, and thus, turn the genes on and off. Epigenetic changes influence dise [...]

Scientific data are almost nonexistent regarding the health-protectiveness of most hazardous-waste-site remediation. Given this data-gap, recently the World Health Organization (WHO) urged scientists to develop methods of "cost-efficient health surveillance" of toxics' cleanups, including any "illegal operations". Following WHO, this article's importance is to develop one such cost-efficient method. Given the assumption that remediators'-redevelopers' public misrepresentations of their cleanups' safety may warrant [...]

Background: T follicular helper (Tfh) and regulatory (Tfr) cells are key players in the formation of long-lived antibody responses. Their circulating counterparts, cTfh and cTfr, are often used as biomarkers because longitudinal sampling of secondary lymphoid tissues is unfeasible in clinical studies. This is the first study to track cTfh and cTfr cells following therapeutic lymphocyte depletion with alemtuzumab, an anti-CD52 monoclonal antibody, to infer the influence of this treatment on the germinal centre respo [...]

Today, the advancement of assessment, forecasting, and therapy or medical attention for psychological healthcare is already using artificial intelligence (AI) technology, particularly machine learning, due to the introduction of digital tools to treat mental health conditions. In mental health treatment, the present and the future of artificial intelligence technologies hold both enormous promises and potential dangers. With the current global scenario, psychological disorders like clinical depression, general anxi [...]

Pancreas or islet transplantation is the only reliable cure for Type 1 Diabetes. However, shortage of donor tissue supply, longitudinal graft attrition due to innate and adaptive immunity and the recurrence of autoimmunity, as well as the harmful side-effects of chronic immunosuppressive therapy limit the wide-spread acceptance of islet transplantation as a mainstream cure for autoimmune diabetes. Herein, preclinical and clinical stem-cells based research approaches aimed at obtaining large quantities of islets for [...]

Lysosomal storage disorders (LSD) are caused by enzymatic failure to degrade specific cellular byproducts of metabolism within the lysosome. They have a wide range of presentations involving multiple body systems and can manifest from infancy through adulthood. As treatments have become available for many of these disorders, newborn screening has been adapted for early identification and pre-symptomatic treatment. This article will review some of the LSD that are now being added to newborn screening panels, includi [...]

Research has shown that compassion – whether to others, from others or to oneself – can be associated with improved well-being and mental health. Most measures to date focus on one of these flows of compassion, with only one recently published scale tracking all three. The primary aim of the current study was to investigate the psychometric properties of The Compassionate Engagement and Action Scales (CEAS) in a UK sample. The secondary aims were to investigate the level of compassion, as measured by th [...]

A conceptual model was developed to create a basis for understanding the risk factors and outcomes associated with dysphagia and to hypothesize the nature of the relationship between certain factors. The conceptual model was developed by two academic speech-language pathologists with ≥10 years research and clinical experience in swallowing and dysphagia in older adults. A comprehensive review of English-language literature was conducted, and relevant, evidence-informed factors associated with dysphagia in older adu [...]
