How Does Plasma Therapy Approach Affect VDR Expression in the Elderly?
Article in Journal of clinical practice and research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: Young plasma is rich in rejuvenating factors that are diminished in aged mice, making it a promising treatment for organ regeneration and hormonal secretion support. Enhancing hormonal renewal suggests that this therapy may influence the expression of vitamin D receptor (VDR), which declines with aging. In this study, plasma therapy was applied to aged rats to evaluate its effects on histomorphological parameters and VDR levels in the jejunum. Materials and Methods: Aged female Wistar rats (12-15 months, n=7) were treated with pooled plasma collected from younger rats (6 months, n=28). Post-treatment, villus height, total mucosal thickness, crypt depth, and surface absorption areas were measured in the jejunum of rats in the experimental group (n=7), control group (n=7), and a positive control young group (YPC) (5 weeks, n=7). VDR expression was assessed using immunohistochemistry, and the number of VDR-positive cells was quantified within 0.01 mm Results: Histomorphological evaluation revealed no statistically significant differences between the experimental group and the YPC group in villus height, total mucosal thickness, and surface absorption area parameters. However, the experimental group exhibited the highest crypt depth compared to the YPC group. Both the YPC and experimental groups demonstrated increases in all parameters, including histological and VDR evaluations, compared to the control group. Conclusion: The plasma treatment supported parameters that facilitate digestion and increased VDR expression, which decreases with aging, thereby exerting a beneficial influence.
