Pneumoconiosis is characterized by chronic lung inflammation and fibrosis, and inflammation can promote pulmonary fibrosis, which in turn leads to pneumoconiosis. When a large shadow with a long diameter of not less than 2 cm and a short diameter of not less than 1 cm appears in the lung, it can be classified as stage Ⅲ pneumoconiosis. This paper reports a case of stage Ⅲ pneumoconiosis with a large shadow in the upper right lung accompanied by burr-like changes misdiagnosed as lung cancer by CT examination.When the large shadow lesions in patients with pneumoconiosis and lung cancer are difficult to distinguish on CT, an additional MRI examination, particularly T(2)W imaging sequence is useful sequence for identifying the two.

In 2025 the changes in national leadership cast a surprising light and ineffable shadows on America's race, gender and class dynamics. Unexpectedly, women and people of color did not vote as a monolithic force in favor of one side or another of culture wars. In the health promotion discipline alarms are being sounded that America's new political leadership will use their newfound popularity among a wider constituency to question the integrity of public health and challenge the value of science writ large.

Owing to critical policy significance, a growing body of literature has been predominantly concentrating on the social welfare benefits brought by green finance (GF) initiatives. However, there is a paucity of research that quantifies the economic costs of GF initiatives on carbon reduction, raising the increasing concerns about the irreconcilable climate-economy trade-offs. To end this, the present study systematically investigates the influence of GF initiatives on the carbon-related marginal abatement cost (MAC) using two competing hypotheses: regulatory versus technical effects.

The efficient acquisition and processing of large-scale terrain data has always been a focal point in the field of photogrammetry. Particularly in complex mountainous regions characterized by clouds, terrain, and airspace environments, the window for data collection is extremely limited. This paper investigates the use of airborne millimeter-wave InSAR systems for efficient terrain mapping under such challenging conditions.

Toxic tuna tales: Tracing microplastic pathways in mackerel tuna (Euthynnus affinis), longtail tuna (Thunnus tonggol), and bullet tuna (Auxis rochei).

Casting a shadow upon marine ecosystems worldwide, microplastic pollution emerges as a formidable threat, yet its repercussions on commercially significant marine fish remain largely unexplored. This investigation delves into the realm of microplastic contamination within three tuna species (Euthynnus affinis, Thunnus tonggol, and Auxis rochei) inhabiting Malaysian waters, with a keen focus on the gastrointestinal tract (GIT), gills, and edible muscle. These species were chosen due to their significant ecological roles and considerable commercial value, being extensively fished and widely consumed across global regions.
