Production and characterization of cellulase-free xylanase from Trichoderma inhamatum

The production of extracellular cellulase-free xylanase from Trichoderma inhamatum was evaluated in liquid Vogel medium with different carbon sources as natural substrates and agricultural or agro-industrial wastes. Optimal production of 244.02 U/mL was obtained with xylan as carbon source, pH 6.0 at 25 degrees C, 120 rpm, and 60-h time culture. Optimal conditions for enzyme activity were 50 degrees C and pH 5.5. Thermal stability of T. inhamatum xylanolytic complex expressed as T(1/2) was 2.2 h at 40 degrees C and 2 min at 50 degrees C. The pH stability was high from 4.0 to 11.0.These results indicate possible employment of such enzymatic complex in some industrial processes which require activity in acid pH, wide-ranging pH stability, and cellulase activity absence.

Influence of IBA and boric acid on rooting of stem-cuttings of Aloysia triphylla (L'Hérit) Britton

Aloysia triphylla (L'Hérit) Britton is a perennial and bushy plant, with simple, entire, lanceolate and whorl shaped leaves and originally from South America. It is used as medicinal plant in Brazil with stomatic and sedative properties. The employment of stem cuttings for propagation of pre-selected plants, acquired great importance, because it eliminates the juvenile phase of seedlings, which can be produced in a shorter period of time. The rooting of stem cuttings is stimulated by auxin and, boric acid supply is essential for growth and development of initial rootlets. This micronutrient is required 48 hours after plant segments have been placed into auxin solution and it can be supplied any time, including the seedling growth period. The experiment was carried out in the Department of Plant Production, UNESP-Botucatu-SP-Brazil, with stem-cuttings of Aloysia triphylla (L'Hérit) Britton, Verbenaceae obtained from the Medicinal and Aromatic Plant Garden. The aim of the work was to verify the influence of growth regulators and boric acid on stem cutting rooting of this species. The 15 cm-stem cuttings, without leaves, were submerged during 24 hs in the following solutions: water; 150 mg.L-1 of IBA; 150 mg.L-1 of IBA+ Boric acid; 250 mg.L-1 of IBA; 250 mg.L-1 of IBA + Boric acid. The statistical design was entirely randomized with 5 treatments and 3 replications, totalizing 15 plots with 10 stem cuttings each. They were planted on propylene trays with vermiculite and kept under spraying condition during twenty five days. The best results were observed in treatment 250 mg.L -1 of IBA+ Boric acid on number of roots, length of roots, rooting percentage, fresh and dry weight of leaves when compared with all other treatments. We can conclude that this treatment is the most suitable for stem cutting rooting of this species.

An assessment of the economic impact of climate change on the Agriculture, Health and Tourism sectors in Saint Lucia

This report analyses the agriculture, health and tourism sectors in Saint Lucia to assess the potential economic impacts of climate change on the sectors. The fundamental aim of this report is to assist with the development of strategies to deal with the potential impact of climate change in Saint Lucia. It also has the potential to provide essential input for identifying and preparing policies and strategies to help advance the Caribbean subregion closer to solving problems associated with climate change and attaining individual and regional sustainable development goals. Some of the key anticipated impacts of climate change for the Caribbean include elevated air and sea-surface temperatures, sea-level rise, possible changes in extreme events and a reduction in freshwater resources. The economic impact of climate change on the three sectors was estimated for the A2 and B2 IPCC scenarios until 2050. An evaluation of various adaptation strategies for each sector was also undertaken using standard evaluation techniques. The key subsectors in agriculture are expected to have mixed impacts under the A2 and B2 scenarios. Banana, fisheries and root crop outputs are expected to fall with climate change, but tree crop and vegetable production are expected to rise. In aggregate, in every decade up to 2050, these sub-sectors combined are expected to experience a gain under climate change with the highest gains under A2. By 2050, the cumulative gain under A2 is calculated as approximately US$389.35 million and approximately US$310.58 million under B2, which represents 17.93% and 14.30% of the 2008 GDP respectively. This result was unexpected and may well be attributed to the unavailability of annual data that would have informed a more robust assessment. Additionally, costs to the agriculture sector due to tropical cyclones were estimated to be $6.9 million and $6.2 million under the A2 and B2 scenarios, respectively. There are a number of possible adaptation strategies that can be employed by the agriculture sector. The most attractive adaptation options, based on the benefit-cost ratio are: (1) Designing and implementation of holistic water management plans (2) Establishment of systems of food storage and (3) Establishment of early warning systems. Government policy should focus on the development of these adaption options where they are not currently being pursued and strengthen those that have already been initiated, such as the mainstreaming of climate change issues in agricultural policy. The analysis of the health sector placed focus on gastroenteritis, schistosomiasis, ciguatera poisoning, meningococal meningitis, cardiovascular diseases, respiratory diseases and malnutrition. The results obtained for the A2 and B2 scenarios demonstrate the potential for climate change to add a substantial burden to the health system in the future, a factor that will further compound the country’s vulnerability to other anticipated impacts of climate change. Specifically, it was determined that the overall Value of Statistical Lives impacts were higher under the A2 scenario than the B2 scenario. A number of adaptation cost assumptions were employed to determine the damage cost estimates using benefit-cost analysis. The benefit-cost analysis suggests that expenditure on monitoring and information provision would be a highly efficient step in managing climate change and subsequent increases in disease incidence. Various locations in the world have developed forecasting systems for dengue fever and other vector-borne diseases that could be mirrored and implemented. Combining such macro-level policies with inexpensive micro-level behavioural changes may have the potential for pre-empting the re-establishment of dengue fever and other vector-borne epidemic cycles in Saint Lucia. Although temperature has the probability of generating significant excess mortality for cardiovascular and respiratory diseases, the power of temperature to increase mortality largely depends on the education of the population about the harmful effects of increasing temperatures and on the existing incidence of these two diseases. For these diseases it is also suggested that a mix of macro-level efforts and micro-level behavioural changes can be employed to relieve at least part of the threat that climate change poses to human health. The same principle applies for water and food-borne diseases, with the improvement of sanitation infrastructure complementing the strengthening of individual hygiene habits. The results regarding the tourism sector imply that the tourism climatic index was likely to experience a significant downward shift in Saint Lucia under the A2 as well as the B2 scenario, indicative of deterioration in the suitability of the island for tourism. It is estimated that this shift in tourism features could cost Saint Lucia about 5 times the 2009 GDP over a 40-year horizon. In addition to changes in climatic suitability for tourism, climate change is also likely to have important supply-side effects on species, ecosystems and landscapes. Two broad areas are: (1) coral reefs, due to their intimate link to tourism, and, (2) land loss, as most hotels tend to lie along the coastline. The damage related to coral reefs was estimated at US$3.4 billion (3.6 times GDP in 2009) under the A2 scenario and US$1.7 billion (1.6 times GDP in 2009) under the B2 scenario. The damage due to land loss arising from sea level rise was estimated at US$3.5 billion (3.7 times GDP) under the A2 scenario and US$3.2 billion (3.4 times GDP) under the B2 scenario. Given the potential for significant damage to the industry a large number of potential adaptation measures were considered. Out of these a short-list of 9 potential options were selected by applying 10 evaluation criteria. Using benefit-cost analyses 3 options with positive ratios were put forward: (1) increased recommended design speeds for new tourism-related structures; (2) enhanced reef monitoring systems to provide early warning alerts of bleaching events, and, (3) deployment of artificial reefs or other fish-aggregating devices. While these options had positive benefit-cost ratios, other options were also recommended based on their non-tangible benefits. These include the employment of an irrigation network that allows for the recycling of waste water, development of national evacuation and rescue plans, providing retraining for displaced tourism workers and the revision of policies related to financing national tourism offices to accommodate the new climate realities.

The therapeutic potential of exercise to treat cachexia

To discuss the role of physical exercise in the attenuation of cancer cachexia-associated symptoms, and upon the outcome of chemotherapy, with special focus on the anti-inflammatory role of chronic exercise. The review addresses the recent findings regarding the positive effects of endurance and strength exercise training upon metabolic dysfunction, systemic inflammation and body composition alterations in the syndrome of cachexia. The employment of different exercise protocol strategies, in respect to intensity, duration, work load and in concomitance with pharmacological treatment is considered. Cachexia is a multifactorial wasting syndrome afflicting patients with cancer, chronic obstructive pulmonary disease, chronic heart failure, trauma, among other diseases. This condition markedly compromises the quality of life, treatment outcome and survival. Recent literature indicates an unequivocal role of chronic exercise in modulating cachexia and other cancer-associated dysfunctions. Exercise is proposed as a complementary treatment in cancer, and represents a function-preserving, anti-inflammatory and metabolism-modulating strategy with low cost, and high versatility and availability. Furthermore, exercise decreases cancer recurrence and presents a positive impact on public health management, reducing hospitalization and medication costs.
