Manganese (Mn) is the twelfth most abundant element on the earth and an essential metal to human health. Mn is present at low concentrations in a variety of dietary sources, which provides adequate Mn content to sustain support various physiological processes in the human body. However, with the rise of Mn utility in a variety of industries, there is an increased risk of overexposure to this transition metal, which can have neurotoxic consequences. This risk includes occupational exposure of Mn to workers as well as overall increased Mn pollution affecting the general public. Here, we review exposure due to air pollution and inhalation in industrial settings; we also delve into the toxic effects of manganese on the brain such as oxidative stress, inflammatory response and transporter dysregulation. Additionally, we summarize current understandings underlying the mechanisms of Mn toxicity.

Despite significant advancements in gene delivery and CRISPR technology, several challenges remain. Chief among these are overcoming serum inhibition and achieving high transfection efficiency with minimal cytotoxicity. To address these issues, there is a need for novel vectors that exhibit lower toxicity, maintain stability in serum-rich environments, and effectively deliver plasmids of various sizes across diverse cell types.

Considering factors such as crustal reserves, atomic mass, redox potential and energy density, sodium-ion batteries (SIBs) are regarded as the most promising alternative to lithium-ion batteries (LIBs). Transition metal-based layered oxides, especially typical NaMnO, stand out among cathode materials due to their low cost and high energy density. However, NaMnO cathodes face several challenges, including Jahn-Teller distortion, manganese dissolution, structural collapse, irreversible phase transition and significant capacity loss.

The extrudates were processed using a twin screw extruder and analyzed for their nutritional and anti-nutritional properties. The findings revealed a rising pattern in the content of fiber, moisture, protein, ash and fat as the substitution of Bambara groundnut increased in the extrudate.

Objectives: Increasing research has shown that heavy metal as a neurotoxicant affects cognitive function across the lifespan. Nutritional status may modify susceptibility to heavy metal exposures, which further impacts cognition.
Methods: We conducted a comprehensive search for cross-sectional studies, longitudinal studies, case-control studies and clinical trials on the interaction between nutrient and heavy metal, as well as mixed heavy metal exposure, in relation to cognition across the lifespan.

Radiotherapy and chemotherapy are widely employed as primary non-surgical cancer treatments; however, their non-selective cytotoxicity often leads to adverse events such as oral mucositis (OM), particularly in head and neck cancer therapies. International guidelines provide recommendations for managing chemoradiotherapy-induced OM in various clinical contexts. Subsequently, emerging researches have introduced evidence supporting novel approaches or existing regimens for OM prevention and treatment.
