Abstract
Ischemic stroke is a devastating disease that causes morbidity and mortality. Malnutrition following ischemic stroke is common in stroke patients. During the rehabilitation, the death rates of stroke patients are significantly increased due to malnutrition. Nutritional supplements such as protein, vitamins, fish, fish oils, moderate wine or alcohol consumption, nuts, minerals, herbal products, food colorants, marine products, fiber, probiotics and Mediterranean diets have improved neurological functions in stroke patients as well as their quality of life. Platelets and their mediators contribute to the development of clots leading to stroke. Ischemic stroke patients are treated with thrombolytics, antiplatelets, and antithrombotic agents. Several systematic reviews, meta-analyses, and clinical trials recommended that consumption of these nutrients and diets mitigated the vascular, peripheral, and central complications associated with ischemic stroke (Fig. 2). Particularly, these nutraceuticals mitigated the platelet adhesion, activation, and aggregation that intended to reduce the risks of primary and secondary stroke. Although these nutraceuticals mitigate platelet dysfunction, there is a greater risk of bleeding if consumed excessively. Moreover, malnutrition must be evaluated and adequate amounts of nutrients must be provided to stroke patients during intensive care units and rehabilitation periods. In this review, we have summarized the importance of diet and nutraceuticals in ameliorating neurological complications and platelet dysfunction with an emphasis on primary and secondary prevention of ischemic stroke.

Abstract
Red and white cabbages (Brassica oleracea var. capitata f. alba and rubra, respectively) are two of the most commercially valued vegetables in crucifers, well-recognized for their unique sensory and nutritive attributes in addition to a myriad of health-promoting benefits. The current review addressed the differential qualitative/quantitative phytochemical make-ups for the first time for better utilization as nutraceuticals and to identify potential uses based on the chemical makeup of both cultivars (cvs.). In addition, extraction methods are compared highlighting their advantages and/or limitations with regards to improving yield and stability of cabbage bioactives, especially glucosinolates. Besides, the review recapitulated detailed action mechanism and safety of cabbage bioactives, as well as processing technologies to further improve their effects are posed as future perspectives. White and red cabbage cvs. revealed different GLSs profile which affected by food processing, including enzymatic hydrolysis, thermal breakdown, and leaching. In addition, the red cultivar provides high quality pigment for industrial applications. Moreover, non-conventional modern extraction techniques showed promising techniques for the recovery of their bioactive constituents compared to solvent extraction. All these findings pose white and red cabbages as potential candidates for inclusion in nutraceuticals and/or to be commercialized as functional foods prepared in different culinary forms.

Abstract
Cardiovascular diseases (CVDs) are a primary cause of deaths worldwide. Thrombotic diseases, specifically stroke and coronary heart diseases, account for around 85% of CVDs-induced deaths. Platelets (small circulating blood cells) are responsible for the prevention of excessive bleeding upon vascular injury, through blood clotting (haemostasis). However, unnecessary activation of platelets under pathological conditions, such as upon the rupture of atherosclerotic plaques, results in thrombus formation (thrombosis), which can cause life threatening conditions such as stroke or heart attack. Therefore, antiplatelet medications are usually prescribed for people who are at a high risk of thrombotic diseases. The currently used antiplatelet drugs are associated with major side effects such as excessive bleeding, and some patients are resistant to these drugs. Therefore, numerous studies have been conducted to develop new antiplatelet agents and notably, to establish the relationship between edible plants, specifically fruits, vegetables and spices, and cardiovascular health. Indeed, healthy and balanced diets have proven to be effective for the prevention of CVDs in diverse settings. A high intake of fruits and vegetables in regular diet is associated with lower risks for stroke and coronary heart diseases because of their plethora of phytochemical constituents. In this review, we discuss the impacts of commonly used selected edible plants (specifically vegetables, fruits and spices) and/or their isolated compounds on the modulation of platelet function, haemostasis and thrombosis.

Abstract
Red cabbage anthocyanins are of great interest as natural food colorants in the food industry; as they represent the color over a broad range of pH-values compared to anthocyanins from other natural sources. It is important to select an appropriate technique with high recovery of anthocyanins from red cabbage, among which extraction with organic solvents is the most applied extraction method. Currently, novel extraction techniques are employed as an alternative to the solvent extraction method, providing advantages such as higher anthocyanin recovery in a shorter time, lower solvent utilization, and minimum quality degradation. However, the incorporation of extracted anthocyanins into foodstuffs and pharmacological products is limited due to their low bioavailability and relative instability toward environmental adverse conditions, such as pH, temperature, enzymes, light, oxygen and ascorbic acid. In addition to increased structural stability of anthocyanins through glycosylation and acylation, their stability could be improved by copigmentation and encapsulation.

Abstract
The interactions between six anthocyans (cyanidin-3-O-glucoside, delphinidin-3-O-glucoside, malvidin-3-O-glucoside, cyanidin-3-O-rutinoside, delphinidin-3-O-rutinoside, malvidin-3-O-rutinoside) and cyclodextrins were investigated by means of computational techniques. Four different structures of the aforementioned anthocyans were considered, as a result of the dependence structure - pH value (flavylium cations in acidic medium, hemiketals in neutral solutions and two tautomeric quinones in alkaline environment). The results outlined that the anthocyanidin-3-O-rutinoside are favored for the obtaining of inclusion complexes with the cyclodextrins, mostly due to the larger number of OH groups involved in the formation of hydrogen bonds. For all the four types of structures, best results have been obtained for β- and γ-cyclodextrins.

Abstract
Artesunate (ART) is a semi-synthetic derivative of artemisinin used in the treatment of patients with malaria, which has also been reported to have immunoregulatory, anticancer and anti-inflammatory properties. The aim of the present study was to investigate the possible beneficial effects of ART on ulcerative colitis (UC) rats and to detect the possible mechanisms underlying these effects. A UC rat model was established using dextran sulfate sodium (DSS). Rats were randomly divided into the following groups: Normal control, UC model group, UC rats treated with a low, medium or high dose of ART (10, 30 and 50 mg/kg/day, respectively), and the positive control group (50 mg/kg/day 5-aminosalicylic acid). The damage status of colonic mucosal epithelial tissue was investigated by hematoxylin and eosin staining, and then the weight, colon length and disease activity index (DAI) were measured. Western blotting and reverse transcription-quantitative polymerase chain reaction analysis were used to detect the levels of cytokines associated with UC and proteins associated with Toll-like receptor 4 (TLR4)-nuclear factor (NF)-κB pathway. ELISA was also performed to measure the levels of inflammatory cytokines. In addition, the viability and infiltration of RAW264.7 cells were examined using Cell Counting Kit-8 and Transwell assays. The results demonstrated that treatment with ART significantly alleviated the UC symptoms induced by DSS in the rat model, lowered the DAI, ameliorated pathological changes, attenuated colon shortening, inhibited the levels of pro-inflammatory mediators and myeloperoxidase activity, and increased hemoglobin expression. Additionally, inflammatory and apoptotic markers were found to be significantly downregulated following treatment with ART in UC rats and RAW264.7 cells. To the best of our knowledge, the present study is the first to demonstrate that ART exerts anti-inflammatory effects via regulating the TLR4-NF-κB signaling pathway in UC.

Abstract
In this study, the chemical profiles and antioxidant activities of red cabbage anthocyanin (RCA)-enriched extract are evaluated. The effects of column temperature on the HPLC resolution of the RCAs are studied. The HPLC resolutions became better as the column temperature increased from 20 °C⁻45 °C. An optimized HPLC condition was achieved at 45 °C and used for the quantification and qualification of the RCAs. The anthocyanins in the enriched powder are all derivatives of cyanidin (268 ± 2 μg/mg), mainly with 19% nonacylated, 51% monoacylated, and 31% diacylated structures with ferulic, sinapic, p-coumaric, and caffeic acids characterized by HPLC-MS. The RCA extracts markedly reduced intracellular oxidative stress production by H₂O₂ on HepG2 cells and consequently ameliorated cell apoptosis and improved viability. The analytical method and cellular antioxidant activity demonstration of the RCAs will greatly facilitate their functional applications.

Abstract
High intakes of vegetables have been associated with a lower incidence of cardiovascular diseases (CVD). However, the effect of vegetables on immune function and antioxidant status in human studies have provided contrasting results. In the present study, after a week of run-in period, 38 subjects at risk of CVD were randomly assigned to one of the following 4-week interventions: low vegetable consumption (800 g of vegetables/week) or high vegetable consumption (4200 g of vegetables/week). Vegetables included carrots, topinambur (Jerusalem artichoke, Helianthus tuberosus), tomatoes, red cabbage, and sweet peppers. Blood and salivary samples were collected before and after intervention periods. In addition to clinical, immunological, and antioxidant markers, leukocyte and lymphocyte expression of the gut-homing β7 integrin was evaluated. No significant changes were detected in clinical, immunological, and antioxidant markers in biological samples, except for an increase in white blood cell count for the low vegetable consumption group (p < 0.05). The study provides additional evidence about the uncertainty of providing a clear evidence for vegetables in modulating markers of immune function and antioxidant status. Further studies are needed in order to unravel the mechanism of effect of vegetable consumption in cardiovascular prevention.

Abstract
Cocoplum (Chrysobalanus icaco L.) (CP) is an anthocyanin-rich fruit found in tropical areas around the globe. CP polyphenols are associated with beneficial effects on health, including reduction of inflammation and oxidative stress. Due to its functional properties, the consumption of this fruit may be beneficial in the promotion of human health and reduce the risk for chronic diseases. The objective of this study was to assess the anti-inflammatory and anti-proliferative activities of anthocyanins extracted from CP (1.0 to 20.0 μg ml-1 gallic acid equivalents [GAE]) in CCD-18Co non-malignant colonic fibroblasts and HT-29 colorectal adenocarcinoma cells. Tumor necrosis factor alpha (TNF-α, 10 ng mL-1) was used to induce inflammation in CCD-18Co cells. CP anthocyanins were identified and quantified using HPLC-ESI-MSn. The chemical analysis of CP extract identified delphinidin, cyanidin, petunidin and peonidin derivatives as major components. Cell proliferation was suppressed in HT-29 cells at 10.0 and 20.0 μg ml-1 GAE and this was accompanied by increased intracellular ROS production as well as decreased TNF-α, IL-1β, IL-6, and NF-κB1 expressions at 20.0 μg ml-1 GAE. Within the same concentration range, there was no cytotoxic effect of CP anthocyanins in CCD-18Co cells and TNF-α-induced intracellular ROS-production was decreased by 17.3%. IL-1β, IL-6 and TNF-α protein expressions were also reduced in TNF-α-treated CCD-18Co cells by CP anthocyanins at 20.0 μg ml-1 GAE. These results suggest that cocoplum anthocyanins possess cancer-cytotoxic and anti-inflammatory activities in both inflamed colon and colon cancer cells.

Abstract
BACKGROUND Arachidonic acid metabolism by cyclooxygenase (COX) is a major pathway for blood platelets' activation, which is associated with pro-thrombotic platelet activity and the production of pro-inflammatory mediators. Inhibition of COX activity is one of the major means of anti-platelet pharmacotherapy preventing arterial thrombosis and reducing the incidence of cardiovascular events. Recent studies have presented that a silymarin (standardized extract of Milk thistle (Silybum marianum)) can inhibit the COX pathway. Accordingly, the aim of our study was to determine the effects of three major flavonolignans (silybin, silychristin and silydianin) on COX pathway activity in blood platelets. METHODS We determined the effect of flavonolignans on arachidonic acid induced blood platelet aggregation, COX pathway metabolites formation, as well as COX activity in platelets. Additionally, we analysed the potential mechanism of this interaction using the bioinformatic ligand docking method. RESULTS We observed that tested compounds decrease the platelet aggregation level, both thromboxane A2 and malondialdehyde formation, as well as inhibit the COX activity. The strongest effect was observed for silychristin and silybin. In our in silico study we showed that silychristin and silybin have conformations which interact with the active COX site as competitive inhibitors, blocking the possibility of substrate binding. CONCLUSIONS The results obtained from this study clearly present the potential of flavonolignans as novel antiplatelet and anti-inflammatory agents.

Flavonolignans inhibit ADP induced blood platelets activation and aggregation in whole blood. Int J Biol Macromol 2016; 95:682-688. [PMID: 27923566 DOI: 10.1016/j.ijbiomac.2016.12.002] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2016] [Revised: 11/26/2016] [Accepted: 12/03/2016] [Indexed: 02/03/2023]
Abstract
Flavonolignans are a group of active chemical compounds presented in the silymarin - a standardized extract obtained from fruits and seeds of Milk thistle (Silybum marianum L. Gaernt.). Since the 70s of the last century, flavonolignans have been regarded to the official medicine as a substances having hepatoprotective properties. However many researches performed in recent years have demonstrated that flavonolignans posses many other healthy properties including modulation of variety cell-signaling pathways. The aim of our study was to examine the effects of three major flavonolignans (silybin, silychristin and silydianin) on ADP-induced blood platelet activation using the flow cytometry analysis as well as determine the mechanism of this interaction by bioinformatic ligand docking method. We observed that all tested flavonolignans in dose-dependent manner inhibit formation of blood platelet aggregates and microparticles as well as decrease expression of P-selectin and activation of integrin αIIbβ3. Our computer-generated models confirm the flow cytometry analysis. We observed that all tested flavonolignans have conformations which are able to bind to the extracellular domain of P2Y12 receptor and probably block interaction with ADP. Our studies may help in the development of a new potential anti-platelet agent, which might be an alternative to the current using drugs.

Abstract
Melatonin is a conserved substance, which was discovered in the evolutionary distant organisms like bacteria, plants, invertebrates and vertebrates. Recent studies have shown that melatonin despite its possible role in photoperiod processes, has been found to be a direct free radical scavenger and an indirect antioxidant. In this report the impact of exogenous melatonin on the Bax inhibitor-1 (BI-1) expression level in Nicotiana tabacum L. line Bright Yellow 2 (BY-2) suspension cells exposed to lead was examined. BI-1 is a well-conserved protein in plants and animals that serves as the inhibitor of mammalian proapoptotic proteins as well as plant ROS-induced cell death. Our results showed that pretreatment with 200 nm melatonin, expressing BI-1 and fortified tobacco suspension cells against damages induced by lead. The obtained results revealed, that melatonin significantly increases BY-2 cells proliferation and protects BY-2 cells against death. Moreover, the conducted analyses showed for the first time that the protective effect of melatonin may be connected not only with its antioxidant properties but also with its direct impact on elevating BI-1 expression and lead-induced programmed cell death (PCD) restriction.
