Acute and chronic exposures to non-essential toxic metals or excessive essential metals cause various diseases including cancer in humans. However, the underlying mechanisms have not been well understood. Long non-coding RNAs (lncRNAs) refer to RNA transcripts that have more than 200 nucleotides but do not have significant protein coding capacities. While lncRNAs were once considered transcription noise, they have become increasingly recognized as crucial players in various physiological and pathogenesis processes. The goal of this article is to review and discuss recent studies that show important roles of lncRNA dysregulations in metal toxicity and carcinogenesis.</p><p><strong>Recent findings: </strong>Recent studies showed that metal exposures dysregulate expression of lncRNAs in cultured cells, animals and humas. However, only a few studies determined the mechanisms of how metal exposure dysregulated expression of lncRNAs. The majority of the studies reported the association of abnormally expressed lncRNAs with various toxic effects of metal exposures, only limited studies established causal relationships demonstrating causal roles of dysregulated lncRNAs in metal toxicity and carcinogenesis. Mechanistically, most studies reported that dysregulated lncRNAs functioned as microRNA sponges to regulate gene expression, much less studies explored other mechanisms of lncRNA actions. It is evident that metal exposures dysregulate expression of lncRNAs, which may serve as novel mediators in metal toxicity and carcinogenesis.

One pivotal mechanism for addressing societal expectations on air pollution and human health is to employ strategic modeling within the urban planning process. This review synthesizes research to inform coordinated strategies for a healthy society. Through strategic modeling in urban planning, we seek to uncover integrated solutions that mitigate air pollution, enhance public health, and create sustainable urban environments.</p><p><strong>Recent findings: </strong>Successful urban planning can help reduce air pollution by optimizing city design with regard to transportation systems. As one specific example, ventilation corridors i.e. aim to introduce natural wind into urban areas to improve thermal comfort and air quality, and they can be effective if well-designed and managed. However, physical barriers such as sound walls and vegetation must be carefully selected following design criteria with significant trade-offs that must be modeled quantitatively. These tradeoffs often involve balancing effectiveness, cost, aesthetics, and environmental impact. For instance, sound walls are highly effective at reducing noise, provide immediate impact, and are long-lasting. However, they are expensive to construct, visually unappealing, and may block views and sunlight. To address the costly issue of sound walls, a potential solution is implementing vegetation with a high leaf area index or leaf area density. This alternative is also an effective method for air pollution reduction with varying land-use potential. Ultimately, emission regulations are a key aspect of all such considerations.

Overall, across the literature, it is clear that Cr(VI) causes neoplastic transformation and lung cancer.

Based on the studies reviewed, we recommend six strategies for designing effective, evidence-based geovisualizations, synthesizing evidence from the cognitive sciences, cartography, and environmental health. These strategies include: Displaying only key data, tailoring and testing geovisualizations with the desired audience, using salient cues, leveraging emotion, aiding pattern recognition, and limiting visual distractions.
