Terminalia species is a widely available plant that can be used to synthesise silver nanoparticles (AgNPs) and harness their catalytic capacity. This experimental design will explore the potential of Terminalia AgNPs in contributing to the degradation process of toxic chemicals generated by industries such as textiles, food, and pharmaceuticals. This research uses four leaf varieties of Terminalia species—T. arjuna, T. bellirica, T. chebula, and T. catappa—to synthesize AgNPs, evaluate their optimal synthesis condi [...]

Biliary atresia (BA), a severe pediatric liver disease of unknown etiology, causes neonatal jaundice, progressive cholestasis, and life-threatening liver fibrosis. Emerging evidence suggests microRNAs (miRNAs) – small non-coding RNAs that regulate gene expression by binding target mRNAs may play a role in BA pathogenesis. Circulating miRNAs have shown diagnostic potential for various diseases, prompting our investigation of miR-21 and miR-19 as potential biomarkers in BA. We conducted a case-control study comparing [...]

Recent work with people with blindness and intellectual disability assessed a technology-aided program intended to help eight participants travel indoor routes to reach relevant destinations. The technology included a smartphone, two barcode readers worn by the participants at their ankles, barcodes displayed at specific points of the travel routes, and a mini speaker. The technology ensured that participants received verbal instructions on how to proceed (e.g., take a left turn, cross from one side to the other of [...]

Though the role of clinical histocompatibility testing is fundamental to successful transplant, systematic risk assessment and mitigation strategies remain underutilised in this domain. This review addresses risk identification, analysis, and control measures across the pre-analytical, analytical, and post-analytical phases of clinical histocompatibility testing, in line with international standards such as ISO 15189:2022. A structured, risk-based quality management system (QMS) is imperative for ensuring accurate [...]

The development and utilization of pharmaceuticals, notably antiretrovirals (ARVs), have significantly enhanced both human quality of life and life expectancy. Nevertheless, the excretion of these compounds into aquatic environments, often exacerbated by inadequate sanitation infrastructure, poses considerable risks to biota. This investigation evaluated the environmental impact of 14 ARVs consumed within the municipality of Belo Horizonte (BH), Brazil. The assessment employed the Environmental Risk Assessment (ERA [...]

This research introduces a blockchain framework to improve security and transparency for the use of renewable energy in power systems. The framework utilizes a permissioned blockchain architecture and IoT-based real-time monitoring to ensure data integrity and confidentiality and support efficient peer-to-peer (P2P) energy trading. Compared with traditional centralized energy management systems, the proposed design increases transaction security by 35%, decreases verification wait times by 28%, and decreases the ri [...]

Severe trauma has a significant impact on self-attitudes and emotions, such as self-criticism and shame, and psychological symptoms. This topic has been more well studied among populations with Trauma and Stress-Related Disorders, but examined to a lesser extent in other clinical populations where adverse life events and potentially traumatic events are highly prevalent, such as Hoarding Disorder. The current study examined trauma exposure, and the relationships between trauma, self-criticism, shame, and symptom se [...]

A significant social stigma is associated with loneliness. The prevalence of social isolation, in the dawn of the 21st century points to the growing isolation in America. Lonely people who commonly display negative self-perceptions, show great difficulty to establish social ties, and that may be related to their personal inadequacies, or socially undesirable attributes. Lonely people suffer from a low social perception, painting them as less psychologically adjusted, and not very capable in relating to others. That [...]

The rising pollution levels in congested urban areas pose a serious threat to human health. Many solutions have been proposed to control and reduce gas emissions from road traffic, with results that are not entirely satisfactory. The adoption of new techniques and methodologies for early detection of pollutant emissions may enable effective management and control of road traffic contamination. The proposed method introduces an interactive protocol that facilitates communication between the traffic control center an [...]

While radiotherapy is one of the main treatments for head and neck cancer, adverse effects limit its effectiveness and affect patients' quality of life. Although various radioprotective substances have been proposed, comprehensive strategies are needed to modulate radiotoxicity. In this regard, compounds from green tea (Camellia sinensis), with antioxidant, anti-inflammatory, and antiproliferative properties, could be suitable for optimizing the radiotherapy relationship. A descriptive, prospective study was conduc [...]
