Abstract Title: 

Blueberry anthocyanin alleviate perfluorooctanoic acid-induced toxicity in planarian (Dugesia japonica) by regulating oxidative stress biomarkers, ATP contents, DNA methylation and mRNA expression.

Abstract: 

Blueberry anthocyanin (BA) have strong health benefits as an active natural antioxidant and perfluorooctanoic acid (PFOA) can result in oxidative stress in animals. In our study, the protective effects of BA against stress induced by PFOA was investigated in the planarian Dugesia japonica using oxidative stress biomarkers, ATP contents, ATPase activity, DNA methylation and mRNA expression. PFOA exposure could resulted in malondialdehyde production. At the same time, treatment with BA decreased the production of malondialdehyde in BA-exposed and co-treatment planarians. PFOA caused activities increase in glutathione peroxidase (GPx), glutathione S-transferase (GST) and activities decrease in glutathione reductase (GR). PFOA exposure decreased the GSH and ATP contents. Additionally, it increased the GSSG contents and ATPase activity. BA administration increased the activities of GPx, GST and GR in BA and co-treatment planarians. Meanwhile BA maintained the contents of ATP, ATPase activity, GSH and GSSG by alleviating PFOA toxicity. Moreover, PFOA and BA increased the contents of 5-methylcytosine and decreased 5-hydroxymethylcytosine in all group. In addition, PFOA and BA treated planarians significantly altered the expression of genes associated with above biochemical parameters. The results showed that the mRNA expression of gpx, Djgst, gr, Djnak and dnmt1 were significantly elevated in all groups. Alterations in the mRNA expression levels indicated a stress response to PFOA exposure and anthocyanin protection. These alterations regulated biomarkers of oxidative stress, energy metabolism and DNA methylation levels in planarians. These results indicate that BA attenuated PFOA-induced oxidative stress, energy metabolism, DNA methylation and gene expression disorders.

Abstract Title: 

Neuroprotective effects of blueberry anthocyanins against perfluorooctanoic sulfonate on planarian Dugesia japonica.

Abstract: 

In this study, the planarian Dugesia japonica was exposed to perfluorooctane sulfonate (PFOS) and blueberry anthocyanins (ANT) for 1-10 days to investigate the protective effects of ANT on neurotoxicity and DNA damage induced by PFOS. The expression of neural related genes (Djnlg, DjFoxD, DjFoxG, DjotxA, and DjotxB) in D. japonica following exposure was determined using quantitative real-time PCR (qPCR). Immunofluorescence was performed to determine the alterations in neural morphology. In addition, ELISA kits were used to measure level of the neurotransmitters Dopamine (DA), serotonin (5-HT) andγ-aminobutyric acid (GABA). Furthermore, single cell gel electrophoresis was measured to analyze DNA damage. In this study, PFOS treatment induced neural morphology defects, alterations in neural-related gene expression, alterations in neurotransmitter levels, and DNA damage. However, co-exposure to ANT and PFOS mitigated the damage to D. japonica induced by PFOS. Restoration of neurotransmitter contents and neural related genes expression were observed in planarians following co-application of ANT and PFOS, immunofluorescence showed that nerve morphology almost recovered, and DNA damage wasdecreased. The results of this study showed that ANT may have a protective effect against PFOS induced neurotoxicity and DNA damage.

Abstract Title: 

Polyphenol-enriched fraction ofL. protects selenite-induced cataract formation in the lens of Sprague-Dawley rat pups.

Abstract: 

Purpose: As the aging population is increasing, the incidence of age-related cataract is expected to increase globally. The surgical intervention, a treatment for cataract, still has complications and is limited to developed countries. In this study, we investigated whether the polyphenol-enriched fraction of(FH) prevents cataract formation in Sprague-Dawley (SD) rat pups.Methods: Sixty rat pups were randomly divided into six groups: CTL, Se, FH40, FH80, FH120, and Cur80. The cataract was induced with subcutaneous injection of sodium selenite (18μmol/kg bodyweight) on postnatal (P) day 10. All groups, except CTL, were injected with sodium selenite, and the FH40, FH80, and FH120 groups were given gastric intubation with FH40 mg/kg, 80 mg/kg, and 120 mg/kg on P9, P10, and P11. The Cur80 group was also given gastric intubation with curcumin 80 mg/kg on P9, P10, and P11. All rat pups were euthanized on P30.Results: Lens morphological analysis showed that FH dose-dependently inhibited cataract formation. In the Se group, soluble proteins were insolubilized, and the gene expression of theα-, β-, and γ-crystallins was downregulated. However, FH treatment statistically significantly inhibited insolubilization of soluble proteins and downregulation of the gene expression of the α-, β-, and γ-crystallins. In the Se group, the gene and protein levels of m-calpain were downregulated, which were attenuated with FH treatment. In addition, sodium selenite injection caused reduced antioxidant enzymes (superoxide dismutase (SOD) and glutathione peroxidase (GPx)), glutathione (GSH) depletion, and malondialdehyde (MDA) production in the lens. The administration of FH inhibited sodiumselenite-induced oxidative stress in a dose-dependent manner. The mechanism of protection against oxidative stress by FH involves NF-E2-related factor (Nrf-2) and hemoxygenase-1 (HO-1). FH treatment inhibited decrease of Nrf-2 in the nucleus fraction and HO-1 in the cytosol fraction. Finally, the FH treatment protected poly (ADP)-ribose polymerase (PARP) from cleavage, determined with western blotting.Conclusions: FH showed a preventive effect against cataract formation by inhibiting m-calpain-mediated proteolysis and oxidative stress in the lens. These results suggest that FH could be a potential anticataract agent in age-related cataract.

Abstract Title: 

Anti-inflammatory Effects of Northern Highbush Blueberry Extract on anInflammatory Bowel Disease Model.

Abstract: 

Blueberry anthocyanins have the ability to efficiently reach the GI tract and exhibit a broad range of biochemical effects. In the context of inflammatory bowel disease (IBD), they remain a promising complement to current IBD treatments. Here, we investigated the anti-inflammatory and antioxidant capabilities of Highbush blueberrieson two normal colon epithelial cell lines, NCM 356 and CCD 841 CoN using fluorescent microscopy and flow cytometry following stimulation with a pro-inflammatory cytokine cocktail. Treatment with blueberry extract revealed a significant decrease in nuclear and cytoplasmic generated reactive oxygen species (ROS) compared to controls. Additionally, the blueberry extract increased cell viability following treatment with the pro-inflammatory cytokine cocktail. A comparison with previous report on rice callus suspension culture (RCSC) revealed opposing trend with reference to the levels of nuclear and cytoplasmic ROS. It is likely that blueberry extract and RCSC employ different players and pathways to mitigate inflammation.

Abstract Title: 

Herbal Compatibility of Ginseng and Rhubarb Exerts Synergistic Neuroprotection in Cerebral Ischemia/Reperfusion Injury of Rats.

Abstract: 

Objective: Ischemic stroke is a complex multifactorial disease caused by interactions among polygenetic, environmental, and lifestyle factors with limited effective treatments. Multi-herbal formulae have long been used for stroke through herbal compatibility in traditional Chinese medicine (TCM); however, there is still a lack of evidence due to their unimaginable complexity. Herbal pairs represent the simplest and basic features of multi-herbal formulae, which are of great significance in clarifying herbal compatibility. Here, we aim to investigate the neuroprotective effects of the herbal compatibility of Ginseng and Rhubarb on a cerebral ischemia/reperfusion (I/R) injury model of rats.Methods: Male adult SD rats were randomly divided into a sham group, a normal saline (NS) group, a Ginseng group, a Rhubarb group, and a Ginseng + Rhubarb (GR) group, a Carbenoxolone [CBX, gap junction (GJ) specific inhibitor] group, and a GR + CBX group. Each group was further assigned into four subgroups according to ischemic time (6 h, 1 day, 3 days, and 7 days). The cerebral I/R injury model was established according to the modified Zea Longa method. The Neurological Deficiency Score (NDS) was assessed by the Zea-Longa scale; the cerebral infarction area was detected by TTC (2,3,5-triphenyltetrazolium chloride) staining; and the expression of connexin-43 (Cx43) and aquaporin-4 (AQP4) were detected based on an immunofluorescence technique and quantitative real-time-PCR.Results: Compared to the I/R group, both the independent and combined use of Ginseng and Rhubarb can significantly improve NDS (

Abstract Title: 

Blackcurrants (Ribes nigrum): A Review on Chemistry, Processing, and Health Benefits.

Abstract: 

Blackcurrants (BC; Ribes nigrum) are relatively new to the U.S. market; however, they are well known and popular in Europe and Asia. The use of BC has been trending worldwide, particularly in the United States. We believe that demand for BC will grow as consumers become aware of the several potential health benefits these berries offer. The objectives of this review were to provide an up-to-date summary of information on BC based on articles published within the last decade; furthermore, to provide the food industry insights into possibilities for the utilization of BC. The chemistry, processing methods, and health benefits have been highlighted in addition to how the environment and variety impact the chemical constituents of BC. A search for journal publications on BC was conducted, which included keywords such as chemical characterization, health benefits, processing, technologies, anthocyanins (ANC), and proanthocyanidins. This review provides up-to-date information available on the subject. In conclusion, BC and their products have industrial uses from which extractions can be made to produce natural pigments to be used as food additives. BC contain flavonoids, specifically ANC, which provide the fruits with their purple color. BC are a rich source of phytochemicals with potent antioxidant, antimicrobial, and anti-inflammatory properties. Also, BC have the potential to improve overall human health particularly with diseases associated with inflammation and regulation of blood glucose.

Abstract Title: 

Antifatigue Activity and Exercise Performance of Phenolic-Rich Extracts from,, and.

Abstract: 

,, and(CRV) possess a high phenolic compound content with excellent antioxidant activity. Dietary antioxidants can reduce exercise-induced oxidative stress. Consumption of large amounts of phenolic compounds is positively correlated with reduction in exercise-induced muscle damage. Research for natural products to improve exercise capacity, relieve fatigue, and accelerate fatigue alleviation is ongoing. Here, CRV containing a large total phenolic content (13.4 mg/g of CRV) demonstrated antioxidant activity. Ultra-performance liquid chromatography quantification revealed 1.95± 0.02 mg of salidroside in 1 g of CRV. In the current study, CRV were administered to mice for five weeks, and the antifatigue effect of CRV was evaluated using the forelimb grip strength test; weight-loaded swimming test; and measurement of fatigue-related biochemical indicators, such as blood lactate, ammonia, glucose, blood urea nitrogen (BUN), and creatine kinase (CK) activity; and muscle and liver glycogen content. The results indicated that in CRV-treated mice, the forelimb grip strength significantly increased; weight-loaded swimming time prolonged; their lactate, ammonia, BUN, and CKactivity decreased, and muscle and liver glucose and glycogen content increased compared with the vehicle group. Thus, CRV have antifatigue activity and can increase exercise tolerance.

Abstract Title: 

Sulforaphane Protects the Male Reproductive System of Mice from Obesity-Induced Damage: Involvement of Oxidative Stress and Autophagy.

Abstract: 

(1): In recent decades, the prevalence of obesity has grown rapidly worldwide, thus causing many diseases, including male hypogonadism. Sulforaphane (SFN), an isothiocyanate compound, has been reported to protect the reproductive system. This research investigated the protective effect of SFN against obesity-induced impairment in the male reproductive system and explored the potential mechanism involved in mice. (2): One hundred thirty mice were divided into 5 groups (Control, DIO (diet-induced obesity), DIO + SFN 5 mg/kg, DIO + SFN 10 mg/kg, and DIO + SFN 20 mg/kg). The effects of SFN on the male reproductive system were determined based on the sperm count and motility, relative testes and epididymis weights, hormone levels, and pathological analyses. Oxidative stress was determined by measuring malondialdehyde (MDA), total antioxidant capacity (T-AOC), superoxide dismutase (SOD), glutathione (GSH), HO, catalase (CAT), and glutathione peroxidase (GSH-PX) levels. Protein expression of nuclear factor erythroid-2 related factor 2 (Nrf2), Kelch-like ECH-associated protein-1 (Keap1), Microtubule-associated protein light chain 3 (LC3), Beclin1, and P62 were determined by western blotting. (3): High-fat diet (HFD)-induced obesity significantly decreased relative testes and epididymis weights, sperm count and motility, and testosterone levels but increased leptin and estradiol levels. SFN supplementation ameliorated these effects. Additionally, SFN administration inhibited the obesity-induced MDA accumulation and increased the SOD level. Western blot indicated that SFN had an important role in the downregulation of Keap1. Moreover, SFN treatment attenuated obesity-induced autophagy, as detected by LC3 and Beclin1. (4): SFN ameliorated the reproductive toxicity associated with obesity by inhibiting oxidative stress mediated by the nuclear factor erythroid-2 related factor 2/ antioxidant response element (Nrf2/ARE) signaling pathway and recovery of normal autophagy.

Abstract Title: 

Dietary intake ofβ-glucans can prolong lifespan and exert an anti-oxidant action of aged fish Nothobranchius guentheri.

Abstract: 

One of the widely accepted conjectures regarding mechanisms of aging is probably the oxidative stress hypothesis.β-1,3-Glucans, well-known immunostimulants, have been shown to increase non-specific immunity and resistance against infections or pathogenic bacteria in several fish species, but its anti-aging function remains poorly understood. By feeding of β-1,3-glucans to the annual fish Nothobranchius guentheri, we detected the survivorship of the fish and estimated the development of age-related biomarkers at different stages. We first showed that administration of β-1,3-glucans was able to prolong the life span of the fish (p
