In order to increase the speed of analysis of metaphases from chorionic villi direct preparations, we have investigated the use of two automatic scanning devices, the Magiscan II and a version of Metafip (the research laboratory precursor of Cytoscan). The speed, efficiency, and ranking system have been compared to manual scanning. Results show that both machines detect approximately 80 per cent of the total analysable metaphases detected by a trained cytogeneticist. There appears to be reasonable agreement in ranking between methods.

Point of Care (POC) diagnosis provides an effective approach for controlling and managing Neglected Tropical Diseases (NTDs). Electrochemical biosensors are well-suited for molecular diagnostics due to their high sensitivity, cost-effectiveness, and ease of integration into POC devices. Schistosomiasis is a prominent NTD highly prevalent in Africa, Asia, and Latin America, with significant socioeconomic implications such as discrimination, reduced work capacity, or mortality, perpetuating the cycle of poverty in affected regions worldwide.

This review assessed the effect of strategies designed to sustain the delivery of evidenced based interventions (EBIs) which target behavioural risk factors linked to leading causes of chronic disease in clinical and community settings. Seven electronic databases were searched for randomised controlled studies published from earliest record to November 2022. Studies were included if they tested a strategy to sustain the delivery of an EBI within clinical or community settings.

This review focuses on antimicrobial packaging for food safety, critically examining the activity and efficacy of cannabinoids against commonly found microorganisms and exploring their antimicrobial mechanisms. Specifically, the review considers cannabinoids derived from industrial hemp plants, which are characterized by low levels of psychoactive components. It also outlines viable strategies to control the sustained release of cannabinoids from the packaging, enabling extended storage and enhanced safety of food products.

Background: Cervical screening, aimed at detecting precancerous lesions and preventing cancer, is based on cytology and HPV testing. Both methods have limitations, the main ones being the variable diagnostic sensitivity of cytology and the moderate specificity of HPV testing. Various molecular biomarkers are proposed in recent years to improve cervical cancer management, including a number of mRNAs encoded by human genes involved in carcinogenesis.

Aqueous zinc-ion batteries are an appealing electrochemical energy storage solution due to their affordability and safety. Significant attention has been focused on vanadium oxide cathode materials for ZIBs, owing to their high specific capacity, unique layered or tunnel structures, and low cost. Compared to traditional methods for preparing and assembling electrode materials, direct current (DC) magnetron sputtering allows direct synthesis and uniform deposition on current collectors, offering advantages such as simplicity, mild reaction conditions, and strong film adhesion.
