Minimal Risk Doses of Cadmium Exposure Induce Histological and Functional Alterations in the Brown Adipose Tissue of Wistar Rats.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Cadmium exposure, even at doses currently regarded as minimal risk, has been associated with significant metabolic alterations. While its effects on organs such as the liver, kidney, and pancreas have been widely studied, its impact on brown adipose tissue (BAT) remains poorly understood. In this study, we evaluated the effects of oral Cd exposure (15 and 32 ppm) over subacute, subchronic, and chronic periods on BAT functionality and structure in Wistar rats (n = 90). A metabolic, toxicological, and hormonal profile, as well as histology, expression of leptin, PPARγ, PPARα, and UCP-1, and mitochondrial complexes activity, were assessed and analyzed using one-way ANOVA and the Kruskal-Wallis test for quantitative and semiquantitative data. The results revealed progressive metabolic dysfunction, liver and renal impairment, increased free T3, and BAT dysfunction characterized by hypertrophy, downregulation of UCP-1 and PPARα, and disorganization of mitochondrial complexes and supercomplexes. These findings suggest a defect in BAT function and loss of its thermogenic capacity. In conclusion, results demonstrate that chronic Cd exposure induces mitochondrial toxic effects by impairing the function of brown adipose tissue and promoting the development of metabolic diseases, even under exposure levels considered to be of minimal risk.
