Morton L, Paton C, Braakhuis A. The Effects of Polyphenol Supplementation on BDNF, Cytokines and Cognition in Trained Male Cyclists following Acute Ozone Exposure during High-Intensity Cycling. Nutrients 2024; 16:233. [PMID: 38257125 PMCID: PMC10819340 DOI: 10.3390/nu16020233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 01/02/2024] [Accepted: 01/09/2024] [Indexed: 01/24/2024] Open
Abstract
The neurotoxic effects of ozone exposure are related to neuroinflammation and increases in reactive oxygen species (ROS). This study aimed to assess inflammation, Brain-Derived Neurotrophic Factor (BDNF), and cognition in healthy male cyclists following polyphenol supplementation and exercise in an ozone-polluted environment. Ten male cyclists initially completed a maximal incremental test and maximal effort 4 km time trial in ambient air. Cyclists then completed two trials in an ozone-polluted environment (0.25 ppm) following 7 days of supplementation with either polyphenol (POLY) or placebo (PL). Experimental trials consisted of a three-stage submaximal test followed by a 4 km time trial. Blood samples were drawn pre- and post-exercise, and analyzed for BDNF, interleukin 6 (IL-6), interleukin 10 (IL-10) and tumor necrosis factor (TNF-α). The Stroop test and serial subtraction task were performed before ozone exposure and again after the 4 km TT. Serum BDNF increased post-exercise (p < 0.0001), and positive differences were observed post-exercise in the ozone POLY group relative to PL (p = 0.013). Plasma IL-6 increased post-exercise (p = 0.0015), and TNF-α increased post-ozone exposure (p = 0.0018). There were no differences in Stroop or serial subtraction tasks pre- or post-exercise. Exercise increases BDNF in ozone.

J Pharm Biomed Anal 2023; 226:115238. [PMID: 36645985 DOI: 10.1016/j.jpba.2023.115238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 01/03/2023] [Accepted: 01/04/2023] [Indexed: 01/12/2023]
Abstract
Ormosia hosiei Hemsl. et Wils. is an economical and medicinal plant, increasingly cultivated in China; however, its branches and leaves are often pruned as waste. This is the first study focused on the phytochemical profiles and antioxidant, anti-α-glucosidase, anti-tyrosinase, and anti-neuroinflammatory activities of the branches and leaves of O. hosiei. Herein, thirty-seven characteristic compounds were identified by UPLC-MS/MS and twelve were detected for the first time in O. hosiei. Twenty-seven phenolics were further quantified and significant differences in phenolic compositions between the branches and leaves of O. hosiei were observed. The ethanol extracts exhibited promising antioxidant, anti-α-glucosidase, anti-tyrosinase, and anti-neuroinflammatory effects, and the bioactivities significantly correlated with total phenolic content and twelve individual phenolics. Naringin, genistein, vitexin, vitexin-2-O-rhamnoside, syringaresinol and syringaresinol-4-O-β-D-glucopyranoside can be considered potential quality markers of O. hosiei. Our results provided solid evidence that the branches and leaves of O. hosiei deserve more attention and exploitation, considering the potential to be developed as functional foods or herbal medicines.

Abstract
Adzuki bean (Vigna angularis), also called red bean, is a legume of Fabaceae (Leguminosae) family. This crop is native to East Asia and is also commercially available in other parts of the world. It is becoming a research focus owing to its distinct nutritional properties (e.g., abundant in polyphenols). The diverse health benefits and multiple utilization of this pulse are associated with its unique composition. However, there is a paucity of reviews focusing on the nutritional properties and potent applications of adzuki beans. This review summarizes the chemical compositions, physicochemical properties, health benefits, processing, and applications of adzuki beans. Suggestions on how to better utilize the adzuki bean are also provided to facilitate its development as a functional grain. Adzuki bean and its components can be further developed into value-added and nutritionally enhanced products.
