Nitrogen excretion during embryonic development of the green iguana, Iguana iguana (Reptilia; Squamata)

Development within the cleidoic egg of birds and reptiles presents the embryo with the problem of accumulation of wastes from nitrogen metabolism. Ammonia derived from protein catabolism is converted into the less toxic product urea or relatively insoluble uric acid. The pattern of nitrogen excretion of the green iguana, Iguana iguana, was determined during embryonic development using samples from allantoic fluid and from the whole homogenized egg, and in hatchlings and adults using samples of blood plasma. Urea was the major excretory product over the course of embryonic development. It was found in higher concentrations in the allantoic sac, suggesting that there is a mechanism present on the allantoic membrane enabling the concentration of urea. The newly hatched iguana still produced urea while adults produced uric acid. The time course of this shift in the type of nitrogen waste was not determined but the change is likely to be related to the water relations associated with the terrestrial habit of the adult. The green iguana produces parchment-shelled eggs that double in mass during incubation due to water absorption; the eggs also accumulate 0.02. mM of urea, representing 82% of the total measured nitrogenous residues that accumulate inside the allantois. The increase in egg mass and urea concentration became significant after 55. days of incubation then were unchanged until hatching. © 2012 Elsevier Inc.

Development of a natural products database from the biodiversity of Brazil

We describe herein the design and development of an innovative tool called the NuBBE database (NuBBEDB), a new Web-based database, which incorporates several classes of secondary metabolites and derivatives from the biodiversity of Brazil. This natural product database incorporates botanical, chemical, pharmacological, and toxicological compound information. The NuBBEDB provides specialized information to the worldwide scientific community and can serve as a useful tool for studies on the multidisciplinary interfaces related to chemistry and biology, including virtual screening, dereplication, metabolomics, and medicinal chemistry. The NuBBEDB site is at http://nubbe.iq.unesp.br/nubbeDB.html. © 2013 The American Chemical Society and American Society of Pharmacognosy.

The tourism sector and the global economic crisis: development implicatins for the Caribbean

Over the past two years the global economy has experienced substantial economic turmoil, resulting in severe economic contraction. While there has been a recent return to growth, this situation has impacted all economic sectors worldwide. In the highly tourism-dependent region of the Caribbean, the impact of the global economic crisis has been most notable on the tourism sector, which, from the early 1990s, became the key driver of economic growth for the region. The eventual emergence of this sector reflects an economic development history which was previously underpinned by the export of agricultural commodities, and subsequently by the adoption of the import substitution industrialization model as promulgated by Arthur Lewis. This was further stimulated by spectacular economic contraction in Caribbean economies during the 1980s as a result of changes in the global terms of trade for commodities, generally low levels of competitiveness for manufactured goods, as well as weak institutional and governance frameworks. Ultimately, many economies began to reflect fiscal and balance of payments constraints. By the end of the 1990s, too, evidence of declining competitiveness even in the tourism sector began to become apparent particularly when evaluated under the framework of the Butler Tourism Area Life- Cycle (TALC) model. The recent economic crisis, therefore, provides an opportunity to reflect on the overall approach to economic development in the Caribbean, and to assess the implications of the region’s response to the crisis. This analysis makes the case for the future development of the sector to be based on two broad strategies. The first is to deepen the integration of the tourism sector into the broader economy through the diversification of the regional tourism product, as well as the enhancement of linkages with other sectors, while the second is to expand the tourism sector into a total service economy through the introduction of new services. Considering linkages, the development of clusters and value chains to support the tourism sector is identified with respect to agriculture and food, handicraft, and furnishings. Among the new services identified are education, wellness, yachting and boating, financial services, and information and communications technologies (ICT). This overall strategy is deemed to be better suited to the macroeconomic realities of the Caribbean, where high labour costs and other structural rigidities require a high-valued specialty tourism product in order to sustain the sector’s global competitiveness.

Caribbean tourism and agriculture: Linking to enhance development and competitiveness

This study examines current trends in tourism and agriculture in Caribbean countries and the strategy for linking them in order to facilitate their future development. The tourism industry has, in the past, developed largely apart from other sectors such as agriculture. On the other hand, agriculture has developed mainly to satisfy export markets. Domestic agriculture has had limited development and has therefore been displaced to a considerable extent by food imports. The recent promotion of agriculture tourism linkages is an attempt to enhance the local value added of the tourism industry, while at the same time promoting the development of domestic agriculture. However, it is argued that agriculture-tourism linkage per se will not facilitate the development of either tourism or agriculture. The nature of the tourism product in each country has to be understood before effective strategies could be devised for improving competitiveness. A similar approach is also necessary in respect of the agriculture sector. Increased linkage between tourism and agriculture could be enhanced through the adoption of a cluster-based strategy for improving the competitiveness of the tourism sector and for improving the livelihoods of communities and rural areas.

Emergy diagnosis and reflections towards Brazilian sustainable development

This paper presents an environmental emergy-based diagnosis of Brazil compared with Russia, India, China, South Africa and United States. Reflections on the Brazilian sustainable development are presented and discussed based on the evaluations published since 1979. The variation of the emergy per capita for Brazil from 1979 to 2007 indicates that the country's growth is tied to the exploitation of non renewable natural resources which do not directly reflect in the welfare of the population. The total emergy exported per unit of gross domestic product increased in the period, suggesting that the country exports more emergy than that contained in the money received for the exportation. With the help of the emergy indices, the future development of Brazil is explored and discussed. The comparison among the BRICS (Brazil, Russia, India, China and South Africa) countries and United States indicates that what may be appropriate and usable within one country may not be within another and that to achieve the global sustainability two concomitant actions may occur: (i) the reduction of the total emergy use in developed economies, and (ii) the reduction of indigenous resources exportation in developing economies.

Impact of inulin and okara on Lactobacillus acidophilus La-5 and Bifidobacterium animalis Bb-12 viability in a fermented soy product and probiotic survival under in vitro simulated gastrointestinal conditions

The effect of inulin and/or okara flour on Lactobacillus acidophilus La-5 and Bifidobacterium animalis Bb-12 viability in a fermented soy product (FSP) and on probiotic survival under in vitro simulated gastrointestinal conditions were investigated throughout 28 days of storage at 4 °C. Employing a 22 design, four FSP trials were produced from soymilk fermented with ABT-4 culture (La-5, Bb-12, and Streptococcus thermophilus): FSP (control); FSP-I (with inulin, 3 g/100 mL of soymilk); FSP-O (with okara, 5 g/100 mL); FSP-IO (with inulin + okara, ratio 3:5 g/100 mL). Probiotic viabilities ranged from 8 to 9 log cfu/g during the 28 days of storage, and inulin and/or okara flour did not affect the viability of La-5 and Bb-12. Bb-12 resistance to the artificial gastrointestinal juices was higher than for La-5, since the Bb-12 and La-5 populations decreased approximately 0.6 log cfu/g and 3.8 log cfu/g, respectively, throughout storage period. Even though the protective effect of inulin and/or okara flour on probiotic microorganisms was not significant, when compared to a fresh culture, the FSP matrix improved Bb-12 survival on day 1 of storage and may be considered a good vehicle for Bb-12 and could play an important role in probiotic protection against gastrointestinal juices. © 2013 Elsevier Ltd.

Development of a synbiotic low-calorie beverage made from soy and yacon extracts

The objective of this study was to develop a new low-calorie symbiotic beverage made from yacon (prebiotic source) and soy extracts, containing probiotic Bifidobacterium animalis ssp. lactis BB-12. The synbiotic beverage was first produced with a range of sucrose concentrations in order to determine ideal sweetness by an acceptance test using a “just-about-right scale”. Sucrose was then replaced by sucralose or aspartame to produce sugar-free beverages. Characteristics including viable cell numbers, physicochemical properties, sensorial characteristics and fructooligosaccharides content were investigated. The ideal sweetness of the beverages with sucrose, aspartame and sucralose were 7.28%, 0.0486% and 0.0167%, respectively. Sucralose exhibited higher scores in acceptance test and was used to replace sucrose in the low-calorie symbiotic beverage. The synbiotic beverage exhibited counts of Bifidobacterium spp. of 108 CFU·mL-1 , sufficient condition to be considered probiotic. The chemical composition of the product was (g/100 g): 2.91 of protein, 1.41 of fat, 2.41 of total carbohydrate; 0.82 of FOS and 148.22 Kj of energy value. The synbiotic beverage developed in this study may be successful in health applications, due to their functional ingredients (soy, probiotic bacteria and yacon prebiotics) that can afford benefits to health or can present disease-preventing properties, beyond their inherent nutritional value. In addition this low-calorie beverage can be consumed by diabetic individuals and people concerned about the ingestion of calories.
