Little systematic research has been conducted into the symptomatic expression of COVID-19 infections in patients. It is known that symptomatic expression varies between patients, but the nature and extent of this variability is poorly understood. This paper elaborates on the symptoms reported by Chinese patients infected with COVID-19 during the Omicron wave, and compares this with available data from other countries. This was an observational clinical case registry study of Chinese patients with suspected Omicron [...]

Watershed health and integrity are essential to human and ecosystem health and well-being. New River watershed communities in northern Belize, Central America are vulnerable to annual ‘cultural eutrophication’ - natural eutrophication exacerbated by human activity. Human-caused pollution from agriculture, septic effluent, and industrial drainage, in combination with extended drought and the slow flow of New River, has caused more frequent and prolonged periods of eutrophication. In this qualitative study, 42 New Ri [...]

To develop a modular anthropomorphic phantom to evaluate the performance of radiological techniques for detecting pathologies in the temporal bone region. A phantom was constructed using a human skull, temporal bone specimen, and 3D-printed contour of a human skull. The human skull was embedded in tissue-equivalent plastic, with a cavity to hold the plastic jars containing the exchangeable freshly frozen human temporal bones. Subsequently, stepwise introduction and examination of different clinicopathological scena [...]

Completely unknown before the 90s and exceptional up to the 2000s, BK virus nephropathy (BKvN), usually known as polyomavirus-associated nephropathy, has emerged as a significant and severe viral complication in kidney transplantation (KT). More than twenty years after Gardner's discovery of BKv in 1971, Purighalla described, in 1995, the first case of BKvN. Four years later in 1999, Nickeleit et al. published a first series of five cases of BKvN and made very precious and pertinent contributions to understanding t [...]

This survey-based, cross-sectional study explored the independent and synergistic effect of filial piety discrepancy (FPD), acculturation, and living arrangement on the psychological, social, and physical wellbeing of older Chinese immigrants living in Canada. A total of 299 older Chinese immigrants were recruited from community organizations in the Greater Toronto Area. Participants completed questionnaires that assessed demographic information, filial piety, living arrangement, acculturation, and three domains of [...]

Nanotechnology is a fast-rising market in catalytic research; however, the production of eco-friendly nanoparticles remains a significant challenge. In this study, silver nanoparticles (AgNPs) were synthesized from the agro-industrial waste of leaves of C. longa, C. aromatica, C. caesia, C. zedoaria, and C. amada at RT after 24 h, which was confirmed with UV-spectrophotometric evaluation between 320-520 nm. SEM revealed cubic and 30-50 nm AgNPs, while band-gap energy was presented as semi-conductors. Synthesized Ag [...]

Over the past decade, developing geopolymer mixes to replace ordinary Portland Cement (OPC) composites has yielded positive results, leading to extensive research. The incorporation of fibers in geopolymers, besides impacting the mechanical properties, has also significantly impacted durability, mainly when dealing with the most pernicious forms of deterioration resulting from chloride attack, water penetration, sulfate attack, acid attack, as well as freeze-thaw, which occurred through chemical transgression. This [...]

Hyperlipidemia is one of the critical risk factors for cerebrovascular disease. Many studies have emphasized that controlling the lipid level can decrease the risk of cardiovascular and cerebrovascular events. In this article, we studied all types of lipids in stroke patients and wanted to consider any relation between lipid level in admission and outcome. This retrospective, cross-sectional study was conducted at Imam Reza Research and Training Hospital. It was performed on a sample of 2165 patients who visited th [...]

Several therapeutic methods are used to cure acute lymphoblastic leukemia (ALL). Relapsed/refractory B-cell ALL (R/R B-ALL) remains the primary cause of death worldwide due to the limitation of cure. Blinatumomab is a bispecific T-cell engaging antibody used to treat R/R B-ALL. The use of blinatumomab for treating R/R B-ALL has shown to be very efficient, especially as a bridge tool to hematopoietic stem cell transplantation (HSCT). The response to blinatumomab treatment ranged from 69% after two cycles in phase II [...]

Lipase-catalyzed hydrolysis of olive oil has been studied in the absence of emulsifier. A simple mathematical model to predict the hydrolysis rate is derived from a proposed kinetic mechanism of the reaction. The hydrolytic reaction obeys Michaelis-Menten kinetics with a simultaneous second-order enzyme deactivation. The model predictions closely agree with the experimental results.
