Curcumin is a compound extracted from the Curcuma longa L, which possesses a wide range of pharmacological effects. However, few studies have collected scientific evidence on its dual effect on angiogenesis. The present review gathered the fragmented information available in the literature to discuss the dual effect and possible mechanisms of curcumin on angiogenesis. Available information concerning the effect of curcumin on angiogenesis is compiled from scientific databases, including PubMed and Web of Science using the key term (curcumin and angiogenesis). The results were reviewed to identify relevant articles. Related literature demonstrated that curcumin has antiangiogenesis effect via regulating multiple factors, including proangiogenesis factor VEGF, MMPs, and FGF, both in vivo and in vitro, and could promote angiogenesis under certain circumstances via these factors. This paper provided a short review on bidirectional action of curcumin, which should be useful for further study and application of this compound that require further studies.

Dietary phenolic compounds are considered as bioactive compounds that have effects in different chronic disorders related to oxidative stress, inflammation process, or aging. These compounds, coming from a wide range of natural sources, have shown a pleiotropic behavior on key proteins that act as regulators. In this sense, this review aims to compile information on the effect exerted by the phenolic compounds and their metabolites on the main metabolic pathways involved in energy metabolism, inflammatory response, aging and their relationship with the biological properties reported in high prevalence chronic diseases. Numerous in vitro and in vivo studies have demonstrated their pleiotropic molecular mechanisms of action and these findings raise the possibility that phenolic compounds have a wide variety of roles in different targets.

Andean blueberries are wild berries grown and consumed in Ecuador which contain high values of bioactive compounds, mainly anthocyanins, with powerful antioxidant activity. The aim of this study was to evaluate the profile and contents of (poly)phenols and carotenoids in Andean blueberry by HPLC-DAD-MSn and determine a wide range of its biological activities. The antioxidant capacity of this fruit was evaluated in vitro by three different methods and in vivo using the zebrafish animal model, also the toxicity effect was determined by the zebrafish embryogenesis test. Besides, the antimicrobial activity and the capacity of Andean blueberry to produce hemagglutination in blood cells were evaluated. Finally, the bioaccessibility of (poly)phenols and related antioxidant capacity were determined in the different phases of an in vitro digestion. The global results indicated no toxicity of Andean blueberry, weakly bacteriostatic activity, and high contents of anthocyanins and antioxidant capacity, which were partially bioaccesible in vitro (~ 50 % at the final intestinal step), contributing to the knowledge of its health benefits for consumers and its potential use in the food and pharmaceutical industry as functional ingredient.

Natural and synthetic derivatives of benzo-γ-pyrones (i.e. flavones, chromones, and coumarins) and their synthetic analogues possess a wide range of biological properties in vitro and in vivo. In this paper we investigated the influence of two hydrazone compounds of chromones, 3-{[(2-dimethoxytiophosphoryl)-2-methylhydrazono]-methyl}-chromen-4-one (CH-3) and 2-amino-6-chloro-3-[(2-hydroxyethyl)-hydrazonomethyl]-chromen-4-one (A-12), on lipid peroxidation and bFGF concentration in the HL-60 cells. Both of the studied compounds had a significant influence on bFGF and TBARS in ranges -137.20 ~ 380.26% and -81.66 ~ -28.68%, respectively, in comparison with the control (counted as 0%).

Bifidobacteria occupy a special place among various representatives of normal human microbiota. A wide range of probiotic preparations has been obtained based on cultivated strains of various bifidobacteria of the intestinal microbiota. A number of scientific publications noted the immunomodulatory, anticarcinogenic, and antiviral properties of bifidobacteria in vitro and in vivo. Recently, progress has been made in the research and application of this group of microorganisms in genetic engineering. It was established that vaccines against viral and bacterial infections and antitumor substances can be developed on the basis of various strains of bifidobacteria. Bifidobacteria can also be used as adjuvants for other vaccines, as well as delivery systems for biologically active substances to tumors. The prospects for the use of bifidobacteria for the development of recombinant vaccines are discussed. bifidobacteria, medical and biological properties, recombinant vaccines, drug delivery, adjuvants, plasmids This work was funded by the Epidemiology and Microbiology National Research Center.

Cerium oxide nanoparticles (nanoceria) are considered as one of the most promising nanomaterials for biomedical applications. Complex analysis of cytotoxicity, including the assessment of effects on the reproductive system, is required for development of new biomedical materials. In this study, we investigated the effects of ultra-small citrate-stabilized cerium oxide nanoparticles on the development of mouse embryos in vitro and embryogenesis process in vivo. We have shown that nanoceria in a wide range of concentrations do not exert a toxic effect on the development of 2-cell embryos and embryogenesis.

Citrus spp. are among the most widespread plants cultivated worldwide and every year millions of tons of fruit, juices, or processed compounds are produced and consumed, representing one of the main sources of nutrients in human diet. Among these, the flavonoids play a key role in providing a wide range of health beneficial effects. Apigenin, diosmetin, luteolin, acacetin, chrysoeriol, and their respective glycosides, that occur in concentrations up to 60 mg/L, are the most common flavones found in Citrus fruits and juices. The unique characteristics of their basic skeleton and the nature and position of the substituents have attracted and stimulated vigorous investigations as a consequence of an enormous biological potential, that manifests itself as (among other properties) antioxidant, anti-inflammatory, antiviral, antimicrobial, and anticancer activities. This review analyzes the biochemical, pharmacological, and biological properties of Citrus flavones, emphasizing their occurrence in Citrus spp. fruits and juices, on their bioavailability, and their ability to modulate signal cascades and key metabolic enzymes both in vitro and in vivo. Electronic databases including PubMed, Scopus, Web of Science, and SciFinder were used to investigate recent published articles on Citrus spp. in terms of components and bioactivity potentials.

The synthetic peptide [D-Arg1,D-Pro2,D-Trp7,9,Leu1]substance P inhibits the stimulation of DNA synthesis induced in Swiss 3T3 cells by bombesin or vasopressin, but not that induced by a wide range of other growth factors and mitogens. The stimulation induced by 10 pM-3 nM-bombesin is inhibited by 1-30 microM-antagonist in a manner consistent with competition at the bombesin receptor. The inhibition by the antagonist of the stimulation induced by vasopressin suggests a previously unrecognized interaction of the antagonist with vasopressin receptors. The antagonist should be useful in studies of cell proliferation both in vivo and in vitro.
