Magnetic nanoparticle hyperthermia (MNH) emerges as a promising therapeutic strategy for cancer treatment, leveraging alternating magnetic fields (AMFs) to induce localized heating through magnetic nanoparticles (MNPs). However, the interaction of AMFs with biological tissues leads to non-specific heating caused by eddy currents, triggering thermoregulatory responses and complex thermal gradients throughout the body of the patient. While previous studies have implemented the Atkinson-Brezovich limit to mitigate potential harm, recent research underscores discrepancies between this threshold and clinical outcomes, necessitating a re-evaluation of this safety limit.

While progress has been made in recent years, there are still no suitable and accepted , or models that can be used to accurately predict whether a chemical substance has the intrinsic property to cause immune-mediated chemical respiratory allergy, typically manifested as allergic asthma or allergic rhinitis which represents a severe health hazard. Regulatory authorities have relied primarily on clinical evidence (case reports, clinical databases, worker exposure studies) to classify substances as respiratory sensitizers, but this evidence can lack a proven immunological mechanism which is necessary to identify substances which can cause life-long sensitization and clinically relevant allergic symptoms in the respiratory tract in an exposed population (such respiratory allergens may be considered as "true" sensitizers, in analogy to the definition of skin sensitization, and in contrast to respiratory irritants). In light of this, the European Center for Ecotoxicology and Toxicology of Chemicals convened a Task Force to evaluate the types of clinical methods and data sources and the implications of relying on such data for regulatory decision making from a scientific perspective.

This review provides a comprehensive overview of the direct and indirect effects of neonicotinoid pesticides (NEO-P) within African agricultural ecosystems and identifies research gaps, particularly in the monitoring and regulation of pesticide use. We observed a decline in the numbers of NEO-P studies conducted in Africa since 2019 with 40.7% of the countries reporting at least one study to date.

Operating room (OR) personnel are at a high risk for sharp injuries, which can cause serious side effects. The goals of this study are to analyze OR nurses and surgical technologists' experiences and their current level of sharps education. An anonymous survey was sent to a single institution asking whether the participants have been stuck by a sharp, when they were stuck, and their perspective on sharp safety.

This article introduces the occupational disease diagnosis of work-related musculoskeletal disorders such as lumbar and spinal injuries in Germany, and focuses on the research and standard values of the maximum pressure tolerance of intervertebral discs. This article mainly introduces the dose model limits and their applications proposed by the Mainz Dortmund Dosis model (MDD), the judgment of the German Social Court (Bundessozialgericht, BSG), and the German Spinal Research Re evaluation (Deutsche Wirbels ulentudieⅡ, DWSⅡ) ; X-ray manifestations and measurements of intervertebral disc injury; Problems in actual cases and diagnosis. In order to provide reference and inspiration for the occupational diseases diagnosis of work related musculoskeletal disorders in China.
