Circadian Rhythms And Neuroendocrine Dysregulation In Adhd: Therapeutic Insights From Omega-3 Fatty Acids, Ayesha Zafar Iqbal, Patricia Marest Suwindi, Sunny Yin-Shan Chen, Lindsay Liang-Tien Cho, Kuan-Pin Su, Jane Pei-Chen Chang

BioMedicine

Attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopmental condition often accompanied by circadian rhythm disturbances, particularly delayed sleep phase. These involve superchiasmatic nucleus (SCN) dysregulation, altered melatonin secretion, and hypothalamic–pituitary–adrenal (HPA) axis activity, which may be exacerbated by artificial light exposure. Genetic studies further implicate circadian mechanisms, linking ADHD with polymorphisms in clock genes such as PER and CLOCK.

Nutraceuticals, particularly omega-3 polyunsaturated fatty acids (n-3 PUFAs), have been proposed as modulators of circadian rhythms. N-3 PUFAs are essential for brain health and may influence melatonin synthesis and sleep–wake regulation. Preclinical and clinical findings suggest that supplementation can improve cognitive …

Peptide Vaccines For Pediatric High-Grade Glioma And Diffuse Midline Glioma: Current Progress And Future Perspectives, Aron K Mebrahtu, Vatsal Jain, Eliese M Moelker, Alexandra M Hoyt-Miggelbrink, Katayoun Ayasoufi, Eric M Thompson

2020-Current year OA Pubs

High-grade gliomas (HGGs) and diffuse midline gliomas (DMGs) in pediatric patients carry a poor prognosis, necessitating the rapid development of novel therapies. Peptide vaccines represent a safe, repeatable, and rational immunotherapeutic modality aimed at inducing potent, tumor-specific T-cell responses. In this review, we define the scope of current progress by arguing that immunogenicity in children with HGG/DMG hinges on three factors: appropriate antigen class (neoantigen vs. TAA), the use of potent immunoadjuvants, and successful navigation of immune suppression. To address the gap between biological promise and clinical reality, we analyze clinical trials targeting shared tumor-associated antigens (e.g., CMV pp65, Survivin) …
