“…Because the prevalences of the molecular pathways for colorectal carcinoma are different among the three Middle Eastern countries we studied, we speculate that unique environmental exposures or lifestyle factors in the Middle East may interact with genetic factors and be reflected in the differing molecular pathways. For example, numerous wild edible plants are available and consumed exclusively in Jordan (32). The extracts of several of these plants that are consumed for treatment of gastrointestinal disorders possess anti-inflammatory activity, possibly due to inhibition of cyclooxygenase-2 that is important in colorectal neoplasia (33).…”

Purpose: The epidemiology of colorectal carcinoma is well known to differ among countries but the molecular characteristics are usually assumed to be similar. International differences in molecular pathology have not been studied extensively but have implications for the management of patients in different countries and of immigrant patients. Experimental Design: We evaluated the CpG island methylator phenotype pathway characterized by concordant methylation of gene promoters that often silences transcription of the genes, the microsatellite instability pathway, and K-ras and p53 gene status in 247 colorectal carcinomas from the three selected Middle Eastern countries of Egypt, Jordan, and Turkey. Results: Colorectal carcinoma from Egypt had the lowest frequencies of methylation. In multinomial logistic regression analysis, Jordanian colorectal carcinoma more frequently had methylation involving the p16 tumor suppressor gene (odds ratio, 3.5; 95% confidence interval, 1.2-10.6; P = 0.023) and MINT31 locus (odds ratio, 2.3; 95% confidence interval, 1.0-5.1; P = 0.041). The K-ras proto-oncogene was more frequently mutated in colorectal carcinoma from Turkey (odds ratio, 2.9; 95% confidence interval, 1.2-6.7; P = 0.016), but p53 overexpression was more common in both Jordanian and Turkish colorectal carcinoma than in Egyptian cases (odds ratio, 2.5; 95% confidence interval, 1.2-5.5; P = 0.019; and odds ratio, 3.6; 95% confidence interval, 1.8-7.1; P = 0.0003, respectively). The findings inTurkish colorectal carcinoma were most similar to those reported forWestern cases. Conclusions: Colorectal carcinoma from Middle Eastern countries have differing gene methylation patterns and mutation frequencies that indicate dissimilar molecular pathogenesis, probably reflecting different environmental exposures. These molecular differences could affect prevention strategies, therapeutic efficacy, and transferability of clinical trial results.The epidemiology of colorectal carcinoma in developing countries differs from that of developed countries. Colorectal carcinoma in developing countries, including those in the Middle East, is usually characterized by low incidence, young age of onset, left-sided location, poor differentiation, and paucity of precursor adenomas (1 -9). International studies as well as studies in immigrants suggest that environmental factors, especially lifestyle and dietary differences, play a major part in the observed epidemiologic differences.Morphologic and genetic progression to colorectal carcinoma in an adenoma-adenocarcinoma sequence and in hereditary colorectal carcinoma syndromes are well described (reviewed in ref. 10). Chromosomal instability and mutation of the K-ras proto-oncogene and the p53 suppressor gene are common.

“…Most prior studies have focused on traditional medicinal uses (ethnopharmacology) or targeted certain known edible plants used in the Jordanian diet (Tukan et al 1998). Thus, these studies ignored other uses of plants, collection behaviors in general, and the potential of this knowledge to improve livelihoods.…”

Understanding the distribution and floristic features of native forest plants, as well as the reasons that lead local people to collect them, is of great value for planning and implementing forest conservation and rehabilitation projPublished: 8 September 2014 Ethnobotany Research & Applications 386www.ethnobotanyjournal.org/vol12/i1547-3465-12-385.pdf est types, namely Origanum syriacum L., Malva parviflora L., and Arum palaestinum Boiss., and that some plant species are collected from a particular forest type. The main uses of the collected plants are food and medicine. The study results suggest value in taking into account the behavior of people who collect native forest plants when designing fragile forest ecosystem restoration programs. These programs should be community-based in order to achieve ecosystem sustainability and prevent biodiversity erosion. IntroductionThe Mediterranean region has provided examples of human interactions with plants (ethnobotany sensu Jones (1941)) over the past decades through studies of collecting native plants for food and medicine (Aburjai et al. 2007, Ali-Shtayeh et al. 2008, El-Darier & El-Mogaspi 2009, Faker et al. 2009, Rigat et al. 2007. Previous ethnobotanical research in the Mediterranean region has identified about 2,300 different plant and fungi taxa which are gathered and consumed (Rivera et al. 2006). Ethnobotanical data contribute to ecosystem restoration and forest sustainability management programs that involve all stakeholders including communities surrounding forests. This involvement is crucial to achieve the indispensable target "sustainability," both through rewarding people and ecosystems. Choudhary et al. (2008) indicated that today's ethnobotanical studies, including applied projects, have potential to reduce poverty levels. Thus, it is important to define the relationship between people and forest as recommended by Michon et al. (2007), who called for a new concept of land management in which production and conservation are compatible and in which there is no choice to be made between people and nature. Accordingly, this study focused on investigating such a relationship in order to help stakeholders implement effective conservation management plans while also reducing the poverty of the local people.The northern area of Jordan contains three types of forests: pine forest, deciduous oak forest, and evergreen oak forest (Al-Eisawi 1996, El-oqlah et al. 1985, Kaspligil 1956, Lahham et al. 1987, Long 1957, Zohary 1962 These forest areas receive the highest precipitation levels in Jordan, with annual rainfall amounts ranging from 400 to 600 mm. The area is bordered by the Irano-Turanian and Sudanian vegetation territories from the west and the Irano-Turanian and Saharo-Arabian vegetation from the east (Al-Eisawi 1996).Jordan's forest area is less than 1% of the total country. This area is declining both in regard to quality and quantity due to urbanization, shifting olive cropping at the expense of forests, grazing, and climate change,...

“…It has been observed that there is an increased awareness on the importance of wild or semi-wild plants owing to their high vitamins, minerals, essential fatty acids and fibre contents (Tukan et al, 1998). Although conventional food plants have the capabilities of providing most of the nutrients needed for energy, body building, maintenance and regulation of body processes, the need to explore some seemingly unappealing sources of nutrient have become imperative owing to the serious threat to growth, development and survival posed by increasing population, food insecurity and economic crises in most developing nations like Nigeria .…”

The chemical nutrient composition and the phytochemical content of the leaves of Mucuna poggei, an underutilized leafy vegetable were analyzed using standard methods. The result of the proximate compositions analysis showed that the leaves contained moisture (8.25%), crude fibre (30.55%), crude fat (9.45%), ash (7.78%), crude protein (32.38%) and carbohydrate (11.55%). Results of the mineral analysis showed that it contains the following essential minerals: Sodium (68.10mg/100g), potassium (43.21mg/100g), calcium ISSN 2157-6076 2012 www.macrothink.org/jbls 233 (71.71mg/100g), iron (10.56mg/100g), manganese (0.65mg/100g), copper (0.47mg/100g), magnesium (56.05mg/100g), zinc (0.25mg/100g), phosphorus (5.72mg/100g), lead (0.01mg/100g), cobalt (nil) and cadmium (nil). The high protein and fibre contents as well as other proximate components are a desirable attribute. The concentration of iron shows that Mucuna poggei leaves could help in boosting of blood level in anaemic conditions. The phytochemical screening of the leaves revealed the presence of alkaloids, tannins, carbohydrates, terpenoids, balsams and triterpenoids. These results rank the leaves of Mucuna poggei among the best in terms of essential nutrients composition when compared with those of other edible leaves in literature.
