In addition to their hemostatic functions, platelets play an essential role in immunologic interactions, which is confirmed by the observation of an increase in platelet counts in patients with immune-related thrombocytopenia and other autoimmune diseases after immunomodulatory treatment with intravenous human immunoglobulin concentrate. The mechanisms of action of this biological therapeutic option induce the development of therapeutic monoclonal antibodies, agonists, and antagonists that target the complex pathop [...]

This scoping review aims to understand the available research and the quality of evidence about the cost-effectiveness of mindfulness-based interventions when applied to the medical student context. There is considerable literature pertaining to the application of mindfulness-based interventions in this context. However, the links between cost and effectiveness need to be established to ensure the relative integrity of these therapeutic systems. The participants included in the study were medical students (undergra [...]

Given the present emphasis on climate change and CO2 emissions, it is crucial to have specific guidelines to determine and mitigate carbon footprints. The following paper seeks to estimate the carbon emissions in kg of carbon dioxide equivalent from activities at Uniza Technical College and the tree's ability to absorb carbon dioxide through photosynthesis. The primary objective of this study is to determine how the emissions from campus trees can contribute to reducing overall carbon emissions. The methodologies e [...]

Sarcopenia is characterised by progressive and generalised decline in muscle strength, function, and muscle mass. Now recognised as a muscle disease, it is highly prevalent in older adults, with estimates of up to 30% in some populations. Sarcopenia has a complex multifactorial aetiology, including cellular and molecular changes, chronic disease, lower physical activity as well as nutritional deficiency. Sarcopenia is associated with a range of adverse physical and metabolic outcomes leading to disability, morbidit [...]

The axillary intra-aortic balloon pump (ax-IABP) has been proposed as an alternative to the femoral IABP, particularly for patients with comorbidities rendering them unsuitable for fem-IABP insertion. Patient mobilisation with the ax-IABP in situ is deemed an additional potential benefit. We reviewed our experience with the ax-IABP. A single-centre retrospective review of all adult patients undergoing cardiac surgery (including heart transplantation) in a UK quaternary cardiac surgery centre between 2017 and 2021 w [...]

This study investigates the hypothesis that diverse synthesis techniques can yield cellulose-graphene hybrids with tailored properties for specific applications, enabling advancements in flexible electronics, energy storage, environmental remediation, and biomedical devices. We examined and compared multiple synthesis methods, including chemical reduction, in-situ synthesis, green synthesis using natural reducing agents, solvent-assisted approaches, hydrothermal and solvothermal techniques, mechanical and chemical [...]

Regenerating injured nerves is difficult because they have little spontaneous regeneration potential. Advances in tissue engineering and regenerative medicine have emphasized the possibility of biomaterial-based methods for nerve healing. Natural protein-based biomaterials have benefits over synthetic ones, such as biocompatibility, non-immunogenicity, and biodegradability. Silk fibroin, generated from mulberry and non-mulberry silkworms, is especially promising because of its abundance, simplicity of processing in [...]

The concentration of heavy metals in road dust poses significant risks to human health and the environment. This study investigates the characteristics of road dust, focusing on the contamination level of heavy metals like lead (Pb), iron (Fe), and arsenic (As). Road dust samples were collected from various locations in Khulna city. They went through acid digestion to determine the Pb, Fe, and As levels using ICP-OES, and bioavailable iron was assessed by mixing the dust samples with water. This study found no dete [...]

The incidence of antifungal-resistant pathogenic fungi has steadily increased around the globe and calls for an aggressive response. The study aimed to produce and evaluate virgin coconut oil's phytochemical properties and antifungal potentials (VCO). The production of VCO was achieved by hot extraction and natural fermentation methods. Gas Chromatography-Mass Spectrometry (GC-MS) was used to evaluate the active phytochemicals in the VCO. The antifungal activities of VCO against Aspergillus flavus, Aspergillus nige [...]

This work focuses on designing a control unit for improving Proton Exchange Membrane Fuel Cell (PEMFC) performance powering electric vehicles when operating in variable atmospheric pressure conditions, a current situation in mountainous countries with sudden changes in road altitude. The paper studies and analyzes the PEM fuel cell behavior working with hydrogen supply from a pressurized tank and oxygen input from atmospheric air supply in journeys with continuous variation of road level due to the orography. The w [...]
