Epigallocatechin-3-gallate conjugated with selenium nanoparticles prevents neurological complications in rats exhibiting schizophrenia-like behaviors.

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
Introduction: The main catechin in green tea is a flavonoid called (-)-epigallocatechin 3-gallate (EGCG) that possesses significant biological and pharmacological properties. In a rat model of schizophrenia, we examined the neuroprotective and antipsychotic properties of EGCG conjugated with selenium nanoparticles (EGCG-SeNPs) against neurological complications induced by social isolation, including significant behavioral and neurochemical dysfunctions that mimic the symptoms of schizophrenia in it. Methods: Male rats (21-23 days old) were divided into two groups: the social rearing (SR) group and the social isolation-reared (SIR) group (one rat per cage). The experiment lasted for eight weeks. For the last 2 weeks, rats in both SR and SIR were assigned to saline, EGCG (50 mg/kg), sodium selenite (0.5 mg/kg), EGCG-SeNPs (0.5 mg/kg), and risperidone (2.5 mg/kg) treated groups. At the end of the experiment, all rats were subjected to behavioral tests, and the prefrontal cortex tissues from each group were analyzed for oxidative stress parameters, proinflammatory cytokines, neurochemicals, apoptotic markers, and histopa-thological changes. Results: EGCG-SeNPs treatment improved the behavior of rats, significantly decreased the levels of malondialdehyde, nitric oxide, and the pro-inflammatory mediators TNF-alpha, IL-1beta, and NF-κB, raised the expression of antioxidant glutathione, superoxide dismutase, glutathione reductase, and catalase, enhanced monoaminergic and cholinergic transmission, and restored the excitatory-inhibitory amino acid imbalance. Additionally, EGCG-SeNPs improved the histopathological changes in the prefrontal cortex, upregulated the expression oe Bcl-2, and downregulated the expression of the anti-apoptotic Bax and caspase-3. Discussion: These encouraging anti-inflammatory, anti-oxidative, anti-apoptotic, and neuromodulatory activities suggest that EGCG-SeNPs might serve as a naturally derived antipsychotic agent.
