ABSTRACTAlthough fruits and vegetables, sources of carotenoids, are widely available in Brazil, hypovitaminosis A constitutes a serious public health problem. There is lack of information available to the population about the dietary sources of carotenoids and factors affecting their bioavailability.The carotenoids also known as bioactive compounds have been associated with the reduction of the risk for degenerative diseases, such as cancer (modulators of immunological responses), cardiovascular diseases, macular degeneration and cataract.In Brazil the utilization of buriti fruit is not widespread; it is consumed only by the local population of some parts of the North and Central regions. Among those foods, out the foods of buritizeiro, the buriti has the highest content of β-carotene among the numerous foods already analyzed, as well as a source of oleic fatty acid, similar to olive oil.The buriti fruit provides the needs of DRI.s (Dietary Reference Intake) of vitamin A for adult, being a good source of nutrition, knowing the variety of foods that composes a balanced diet. Also, the buriti fruit is a natural source of β-carotene (provitamin A). Also, it has antioxidant power by having carotenoids, polyphenols, vitamin C compared to other vegetables, can be considered a functional food.

Purpose – The purpose of this paper is to characterize food consumption outside the home and verify the existence of relationships between income, expenditure and the prevalence of overweight and obesity in adult individuals in Brazil. Design/methodology/approach – Food expenditure data were used as well as those on the prevalence of overweight and obesity available in the reports from Family Budgets Research carried out by the Brazilian Institute of Geography and Statistics (IBGE) in the years 2002-2003 and 2008-2009. In addition, the authors used the Kruskall-Wallis test to verify whether there were significant differences between the classes of income with respect to the average expenditure on food outside the home. Findings – It was observed that the higher the income of the individual, the greater the expenditure on food outside the home. It was also found that the prevalence of overweight and obesity is higher in individuals who have higher income, particularly among men. Thus, it is suggested that the higher the income of the individual, the larger the expenditure on food outside the home and the greater the prevalence of overweight and obesity. Research limitations/implications – This study used spending on food away from home (FAFH), but the authors know that is need to use other variables like frequency of FAFH and quantities but this data were not available. Practical implications – The study points to the importance of restaurants in the prevention of obesity, since they can offer in their menus foods with fewer calories, and they can also increase the variety and availability of fruits and vegetables. Originality/value – The study discusses the public health problem, obesity, at the same time as it presents the importance of agribusiness in providing a balanced diet for individuals.

Plant carotenoids are one of the most important classes of plant pigments and play a crucial role in defining the quality parameter of fruits and vegetables. They possess a large numbers of important biological activities such as antioxidant properties, anti – carcinogenic, precursor of vitamin A and preventive in a large number of chronic diseases. The objective of the present study was to characterize the carotenoids present in Phoenix sylvestris fruits and their inflorescence axis which are orange red in colour. So, in this study we isolated carotenoids from both the epicarp and the extensively large inflorescence axis by preparative TLC and also characterized some of the major components like β- carotene and lutein using HPTLC analytical techniques. The present findings suggest that the consumption of β-carotene and lutein from this fruit crop can be helpful in providing potential targets for combating vitamin A deficiency in countries where vitamin A deficiency is a public health problem

According to the World Health Organization, leishmaniasis remains a major worldwide public health problem. The province of Sefrou located in the center of Morocco is a focus of cutaneous leishmaniasis. The present study aims at evaluating the antileishmanial potential of Berberis sp.,Crataegus oxyacantha, Cistus salviifolius, Ephedra altissima and Lavandula dentatafrequently used by the local population. Methanolic extracts were tested against the promastigote form ofLeishmania tropica, Leishmania majorandLeishmania infantumusing tetrazolium-based colorimetric (MTT) assay. The total phenol and flavonoids content of all extracts were determined using the Folin–Ciocalteu reagent, aluminum chloride, and potassium acetate solutions respectively. The plant extracts exhibited antileishmanial activity with variability depending on the tested strain and the plant species compared to Glucantime® used as control (IC50 (the half maximal inhibitory concentration) > 1,000 μg/mL). The best inhibition was observed with Berberis sp., againstLeishmania major(IC50 = 394.40 ± 3.02 μg/ml), andEphedra altissima(reported for the first time) againstLeishmania infantum(IC50 = 490.84 ± 3.15 μg/mL).Leishmania tropicahas shown the same sensitivity behavior toward the five extracts (in average IC50 = 540 ± 11.20 μg/mL). The total phenolic content was higher forCrataegus oxyacanthaandCistus salviifolius(140.67 ± 3.17 μg eq Gallic Acid (GA)/ mg of Extract (E) and 133.83 ± 9.03 μg eq GA/mg of E respectively), while flavonoid was higher forCistus salviifoliusandLavandula dentata(57.92 ± 2.46 μg eq Quercetin (Que)/ mg of Extract (E) and 41.53 ± 1.74 μg eq Que/mg of E). All the tested extracts present some promising aspects that may cure cutaneous leishmaniasis in the center of Morocco; further bioguided assays are needed to isolate the fractions and the bioactive molecule.

Spatio Temporal

Based on the fundamental concept of sustainable development, this study empirically analyzes the spatio-temporal characteristics, formation mechanisms and obstacle factors of the urban-rural integration of shrinking cities in China, from 2008 to 2018. The conclusions are as follows: the overall level of the urban-rural integration of shrinking cities in China is low; the internal differences of urban-rural integration are also small, and the changes are slow. Next, the space difference is high in the east and low in the west, high in the south and low in the north. Moreover, differences exist among different levels of urban agglomerations. Urban economic efficiency, urban resources and environment, urban social equity and rural economic efficiency are the main factors affecting the urban-rural integration of shrinking cities in China. Urban and rural economic efficiency are the two most prominent shortcomings that restrict the urban-rural integration of shrinking cities. The spatial resistance mode of each city is more than the two-system resistance; the main resistance of shrinking cities with a higher level of urban-rural integration also comes from the non-economic field. This study expands the research scope that up till now has ignored the discussion of urban-rural issues in the research of shrinking cities at home and abroad, and provides practical guidance for the sustainable development of shrinking cities in China.

Irregular dietary intakes impairs estimations from food records. Biomarkers and method combinations can be used to improve estimates. Our aim was to examine reproducibility from two assessment methods, compare them, and validate intakes against objective biomarkers. We used the Malmö Offspring Study (55% women, 18–71 y) with data from a 4-day food record (4DFR) and a short food frequency questionnaire (SFFQ) to compare (1) repeated intakes (n = 180), (2) intakes from 4DFR and SFFQ (n = 1601), and (3) intakes of fatty fish, fruits and vegetables, and citrus with plasma biomarkers (n = 1433) (3-carboxy-4-methyl-5-propyl-2-furanpropanoic acid [CMPF], β-carotene and proline betaine). We also combined 4DFR and SFFQ estimates using principal component analysis (PCA). Moderate correlations were seen between repeated intakes (4DFR median ρ = 0.41, SFFQ median ρ = 0.59) although lower for specific 4DFR-items, especially fatty/lean fish (ρ ≤ 0.08). Between-method correlations (median ρ = 0.33) were higher for intakes of overall food groups compared to specific foods. PCA scores for citrus (proline betaine ρ = 0.53) and fruits and vegetables (β-carotene: ρ = 0.39) showed the highest biomarker correlations, whereas fatty fish intake from the SFFQ per se showed the highest correlation with CMPF (ρ = 0.46). To conclude, the reproducibility of SFFQ data was superior to 4DFR data regarding irregularly consumed foods. Method combination could slightly improve fruit and vegetable estimates, whereas SFFQ data gave most valid fatty fish intake.

Β Carotene

Vitamin A (VA) deficiency is a worldwide public health problem. Biofortifying existing sources of β-carotene (βC) and increasing dietary βC could help combat the issue. Two studies were performed to investigate the relative βC bioavailability of a βC supplement to purple, high-βC orange, and typical orange carrots using Mongolian gerbils (Meriones unguiculatus). In study 1, which used a traditional bioavailability design, gerbils (n32) received a diet containing orange, purple, or white carrot powder, or white carrot powder +a βC supplement. In study 2, which included βC-biofortified carrots, gerbils (n 39) received orange, high-βC orange, purple, or white carrot powder in their diet. Both studies lasted 21 d and the gerbils were killed to determine the effect of carrot type or supplement on serum and liver βC, α-carotene, and VA concentrations. Liver stores of βC or VA in the gerbils did not differ between orange and purple carrot diets when equal amounts of βC from each of the diets were consumed (P>0·05). Both the orange and purple carrot diet resulted in higher liver VA compared with the supplement (P<0·05). High-βC carrots resulted in more than 2-fold higher βC and 1·1 times greater VA liver stores compared with typical orange carrots (P<0·05). These results suggest that high-βC carrots may be an alternative source of VA to typical carrots in areas of VA deficiency. Second, phenolics including anthocyanins and phenolic acids in purple carrot do not interfere with the bioavailability of βC from purple carrots.

AbstractCulture has been absent from analyses and debates about the responsibility to protect (R2P) norm. The use of the military to enforce a no-fly zone in Libya and to protect civilians took place with support from the local population and more widely across the Arab World even when the dominant 'culture' supposedly made outside interference unthinkable. As R2P enters its second decade, a deeper understanding of culture is desirable, as is the incorporation of cultural perspectives in framing responses to mass atrocities. UN debates and resolutions have helped dispel myths about R2P and reaffirmed its validity as a universal norm that is close to a 'tipping point'. Instead of an 'emerging' norm (the original contention in 2001 by the International Commission on Intervention and State Sovereignty), R2P has 'emerged' as consensus continues to widen and deepen across the North and the global South. This essay shares insights from research about cultural perspectives in the global South from local researchers who explore three themes (religion and spirituality, philosophy and ethics, and art and aesthetics) and three country cases (Rwanda, Kosovo, and Nepal).
