Essential oils from medicinal and aromatic plants: A review of the gastroprotective and ulcer-healing activities

Gastric ulcer is an excoriated area of the gastric mucosa. It is among the predominant gastrointestinal chronic diseases. The essential oils represent an important part of the traditional pharmacopoeia in many countries and have been successfully used for gastroprotection and ulcer healing. Thus, this review presents the experimental activity of essential oils traditionally used in the gastric ulcer prevention and treatment, considering their families, part of the plant studied, bioassays, and their mechanisms of gastroprotection and ulcer healing, with the aim of stimulating novel studies in the search for a new phytomedicine to treat gastric diseases. © 2012 The Authors Fundamental and Clinical Pharmacology © 2012 Société Française de Pharmacologie et de Thérapeutique.

Use of grape polyphenols against carcinogenesis: Putative molecular mechanisms of action using in vitro and in vivo test systems

Polyphenols are present in foods and beverages and are related to sensorial qualities such as color, bitterness, and astringency, which are relevant in wine, tea, grape juice, and other products. These compounds occur naturally in forms varying from simple phenolic acids to complex polymerized tannins. Thus, it is reasonable to expect that grape-derived products elaborated in the presence of skins and seeds, such as wine and grape juice, are natural sources of flavonoids in the diet. Carcinogenesis is a multistep process that is characterized by genetic, epigenetic, and phenotypic changes. With increasing knowledge of these mechanisms, and the conclusion that most cases of cancer are preventable, efforts have focused on identifying the agents with potential anticancer properties. The use of grape polyphenols against the carcinogenesis process seems to be a suitable alternative for either prevention and/or therapeutic purposes. The aim of this article is to show the molecular data generated from the use of grape polyphenols against carcinogenesis using in vivo and in vitro test systems. © Mary Ann Liebert, Inc. and Korean Society of Food Science and Nutrition.

Antimutagenic and anticarcinogenic effects of wheat bran in vivo

Previous studies in rodents treated with the pro-carcinogen 1,2-dimethylhydrazine suggested that the consumption of wheat bran protected against DNA damage in the colon and rectum. Based on this information, we evaluated wheat bran as a functional food in the prevention and treatment of colon cancer. We used the aberrant crypt focus assay to evaluate the anticarcinogenic potential of wheat bran (Triticum aestivum variety CD-104), the comet assay to evaluate its antigenotoxicity potential, and the micronucleus assay to evaluate its antimutagenic potential. The wheat bran gave good antimutagenic and anticarcinogenic responses; the DNA damage decreased from 90.30 to 26.37% and from 63.35 to 28.73%, respectively. However, the wheat bran did not significantly reduce genotoxicity. Further tests will be necessary, including tests in human beings, before this functional food can be recommended as an adjunct in the prevention and treatment of colon cancer. © FUNPEC-RP.

Musculoskeletal disorders (MSDs) in dancers and former dancers participating in the largest dance festival in the world

Objective: To verify the presence of musculoskeletal disorders (MSD) in dancers and former dancers participating in the 27th Joinville Dance FestivalMaterial and methods: The research was conducted at the 27th Joinville Dance Festival in Santa Catarina, Brazil, with 173 participants in the competition, where 139 were dancers and 34 were former dancers with at least ten years of practiceIn order to obtain information related to MSDs, dancers answered a specific questionnaireResults: The study group consisted of adults (28±9 years) with body mass index within the normal range (21.3±2.3) with high weekly training time (955.7±837.2) and featuring long-time experience in dancing (18±7years)The lumbar spine and knees were the most affected by MSDsThe pain of high intensity was the symptom that most often appeared in reports among survey participantsConclusion: It is important to have deeper knowledge of the prevalence of pain among professional dancers, the factors associated with pain conditions and its impact on everyday life in order to plan new forms of prevention and plan new forms of prevention and treatment within a multidisciplinary approach© 2012 Elsevier Masson SAS.

Evaluation of the antimutagenic and anticarcinogenic effects of inulin in vivo

The incidence of colorectal cancer is growing worldwide. The characterization of compounds present in the human diet that can prevent the occurrence of colorectal tumors is vital. The oligosaccharide inulin is such a compound. The aim of this study was to evaluate the antigenotoxic, antimutagenic and anticarcinogenic effects of inulin in vivo. Our study is based on 3 assays that are widely used to evaluate chemoprevention (comet assay, micronucleus assay, and aberrant crypt focus assay) and tests 4 protocols of treatment with inulin (pre-treatment, simultaneous, post-treatment, and pre + continuous). Experiments were carried out in Swiss male mice of reproductive age. In order to induce DNA damage, we used the pro-carcinogenic agent 1,2-dimethylhydrazine. Inulin was administered orally at a concentration of 50 mg/kg body weight following the protocols mentioned above. Inulin was not administered to the control groups. Our data from the micronucleus assay reveal antimutagenic effects of inulin in all protocols. The percentage of inulin-induced damage reduction ranged from 47.25 to 141.75% across protocols. These data suggest that inulin could act through desmutagenic and bio-antimutagenic mechanisms. The anticarcinogenic activity (aberrant crypt focus assay) of inulin was observed in all protocols and the percentages of damage reduction ranged from 55.78 to 87.56% across protocols. Further tests, including human trials, will be necessary before this functional food can be proven to be effective in the prevention and treatment of colon cancer. © FUNPEC-RP.

PLA and Organoclays Nanocomposites: Degradation Process and Evaluation of ecotoxicity Using Allium cepa as Test Organism

In this study, nanocomposites of PLA and organoclays Cloisite 20A and Cloisite 30B were prepared by the melt intercalation method and the obtained samples were characterized by transmission electron microscopy (TEM). Since composting is an important proposal to the final disposal of biopolymers, the influence of clays on the hydrolytic degradation process of PLA was evaluated by visual analysis and monitoring of molecular weight after periods of 15 and 30 days of degradation in compost. After degradation of the materials in composting environment, the evaluation of cytotoxic, genotoxic and mutagenic effects of compost aqueous extract was carried out using a bioassay with Allium cepa as test organism. The TEM micrographs permitted the observation of different levels of dispersion, including exfoliated regions. In the evaluation of hydrolytic degradation it was noted that the presence of organoclays can decrease the rate of degradation possibly due to the barrier effect of clay layers and/or the higher degree of crystallinity in the nanocomposite samples. Nevertheless, even in the case of nanocomposites, the molecular weight reduction was significant, indicating that the composting process is favorable to the chain scission of PLA in studied materials. In the analysis performed by the bioassay using A. cepa as test organism, it was found that after degradation of the PLA and its nanocomposites the aqueous extract of compost samples induced a decreasing in the mitotic index and an increasing in the induction of chromosomal abnormalities. These results were statistically significant in relation to the negative control (distilled water). By comparing the results obtained for the nanocomposites in relative to pure polymer, there were no statistically significant differences. The types of the observed chromosomal aberrations indicated a possible genotoxic effect of the materials, which may be related to an aneugenic action of PLA degradation products. © 2013 Springer Science+Business Media New York.

Trade and Development Nexus: reflections on the performance of trade in goods under the Cariforum-European Union Partnership agreement a Cariforum perspective

Given the asymmetry in the levels of development and capacity which exist between the EU and CARIFORUM States, the architects of the CARIFORUM-European Union (EU) Economic Partnership Agreement (EPA)1 anticipated the need for review and monitoring of the impacts of implementation. Article 5 and other provisions in the Agreement therefore specifically mandate that monitoring be undertaken to ensure that the Agreement benefits a wide cross-section of the population in member countries. The paper seeks to provide a preliminary assessment of the impact of the EPA on CARIFORUM countries. In so doing, it highlights some critical information and implementation gaps and challenges that have emerged during the implementation process. The analysis however, is restricted to goods trade. The services sector will be the subject of a separate report. The paper draws on a combination of quantitative and qualitative analyses. While the paper undertakes a CARIFORUM-wide analysis for the most part, five CARIFORUM member states including Barbados, Dominican Republic, Guyana, Saint Kitts and Nevis and Saint Lucia are examined more closely in some instances. These economies were selected by virtue of economic structure and development constraints, as a representative subset of CARIFORUM, which comprises the CARICOM membership as well as the Dominican Republic.

Global financial rulemaking and small economies

This paper addresses some unintended consequences of global financial regulation and international tax evasion prevention and their impact on small economies. It explores how failure to recognize countries’ differing access to finance and varying costs of funding as well as the high costs of complying with financial regulations may overlook some unintended consequences, especially on smaller island countries Then, it discusses the global financial architecture and governance of standard setting bodies and the actions taken to improve representation and legitimacy and remediate some of the unintended deleterious effects on emerging markets and developing economies (EMDEs). Improving governance is ever more urgent at a time when financing the post-2015 agenda will require mobilization of both public and private funds at the national, regional and global levels.
