“…The levels of ROS and RNS are balanced by two lines of cell defense including the enzymatic (as the first line) and nonenzymatic (as the second line) antioxidants providing maximal protection against OTS via ROS clearing and scavenging (88). Preventive and therapeutic features of antioxidants are well-known and they have been known to have a critical role in protecting biological sites from oxidative injuries (89)(90)(91)(92). By now, many kinds of fruits, vegetables, plant food materials, and dietary supplementation have been investigated for their antioxidant capabilities (92)(93)(94).…”

Context: Oxidative stress is a hallmark of many types of neuropathology disorders and underlying mechanism in several neurodegenerative diseases and brain injuries. The CNS is particularly susceptible to oxidative toxic stress (OTS). Reactive oxygen spices are the basic inflammation and neurotoxicity mediators in ischemia/reperfusion injuries. The purpose of the present review is to provide an overview of some nanoparticles (NPs) in developing OTS conditions and neurological disorders. Evidence Acquisition: Here, a nanotechnology approach is evaluated using NPs in human neuronal protection against OTS. It may be wide therapeutic applications in the case of acute and/or chronic neurodegenerative disorders related to OTS. Results: In the brain of mice treated with nanosize TiO 2 , a significant association was found between the ability to induce the production of ROS and metabolic stress in intracellular environments and inflammatory responses in mice brai. The large surface area of AgNPs may efficiently facilitate the radicals generation including ROS in various organs. The production of ROS may cause DNA damage, cellular apoptosis, and activation of the mitogen activated protein kinase (MAPK) pathways which is responsible for regulating many cellular processes. Prolonged and excessive OTS may contribute to the activation of transcription factors and genes responsible for inflammation responses such as NF-κB and AP-1. Furthermore, OTS may contribute to the onset of neurodegenerative diseases. The ability of CuONPs to generate OTS in vitro studies has been demonstrated; however, information on the neurotoxicity of the CuONPs in vivo is low. Conclusions:The NPs-induced OTS may increase the pro-inflammatory responses. On the other hand, administration of antioxidants such as NAC and vitamin C and E prior to exposure to metal NPs significantly decreases OTS conditions.

“…TPs are the essential ingredient of tea and account for about 30% of the dry green tea weight (Li et al, 2018;Liang et al, 2017;Zhao & Zhang, 2019). Various studies found that these compounds show high antioxidant properties in rabbit (Eid et al, 2011), rainbow trout (Oncorhynchus mykiss) (Thawonsuwan et al, 2010) and inhuman (Kaushik et al, 2011;Meng et al, 2008). These compounds have multiple biological features, such as reducing neurodegenerative disorder (Chastain & Moss, 2015;Kim et al, 2004), inflammation (Suzuki et al, 2009), cardiovascular diseases (Keske et al, 2015;Lecumberri et al, 2013) and cancer (Samadi et al, 2015).…”

Several studies have highlighted the effect of Tea polyphenol (TPs) on growth performance and the gene regulation associated with the metabolic pathway and of various species. However, there is less information about the effect of TPs on growth performance and the regulation of genes related to the metabolic pathway of Grass carp (Ctenopharyngodon idellus). Six diets with different TPs level (0, 250, 500, 1,000, 2,000 and 4,000 mg/kg) were formulated. Result found that TPs increased the feed conversion efficiency (FCE) at different levels, and the highest FCE and specific growth rate (SGR) (p < 0.05) were achieved by the 500 mg/kg in the TPs group. Additionally, transcriptome sequencing of control and TPs groups was performed, and numerous differentially expressed genes (DEGs) were determined in the metabolic pathway of grass carp. The differentially expressed genes were validated by the qRT-PCR technique. DEGs were associated with arachidonic acid metabolism, linoleic acid metabolism, alpha-linolenic acid metabolism, biosynthesis of unsaturated fatty acids, fatty acid biosynthesis and fatty acid degradation. Our findings could provide new insight into the effect of TPs on growth performance and the regulation of genes associated with the metabolic pathway of grass carp.

“…The major active ingredients in green tea are polyphenolic compounds known as catechins (Balentine et al, 1997). These compounds are reported to have high antioxidant activity in humans (Meng et al, 2008;Kaushik et al, 2011), rabbit (Eid et al, 2010) and in rainbow trout (Thawonsuwan et al, 2010). These compounds were reported to stimulate fat oxidation in obese Thais (Auvichayapat et al, 2008) and decrease the immune potency of fish species (Thawonsuwan et al, 2010).…”

To investigate the effects of green tea waste on growth and health of grass carp (Ctenopharyngodon idellus), Green tea waste (GTW) and green tea (GT) were added in the basal diet (BD) of fish by replacing wheat at an inclusion level of 5% to form three diets. 60 grass carp (43.8±2.8 g) were divided into three groups (each group having two replicates) and fed for 66 days. After which growth and health of fish were determined. The results showed that final weight of fish and feed efficiency ratio in GTW group were between BD and GT groups and they were not different compared with BD or with GT groups. Expression of muscle myf5 and myf6 in GTW were between BD and GT group, being significantly lower than BD group. Serum TP, ALB, GLO, HDL, LDL and T-AOC in GTW group were significantly higher than BD group. Expression of hsp 70 and ubiquitin in hepatopancreas of fish in GTW group were significantly higher than BD group. The results suggest that GTW supplementation has positive impact on health of fish without affecting the growth of fish.
