The article titled "Disaster risk reduction from the One Health approach" addresses the importance of intersectorality and transdisciplinarity in integrated disaster risk reduction. It highlights the need to apply the One Health approach to minimize damages and maximize benefits in the joint management of human, animal, and environmental health. The study conducted at the teaching polyclinic "Reina" analyzes the current state of professional performance of the basic primary health care team in disaster risk reduction from this approach. It is concluded that the systematization of the research allowed identifying the theoretical references that support the relationship between One Health and the improvement of professional performance in disaster risk reduction.

Trees of forest importance are a group of special interest for conservation actions due to their use value. To determine whether they can be conserved in seed banks, we studied the tolerance to desiccation and storage behaviour of four species from north-eastern Argentina: Handroanthus impetiginosus, Jacaranda mimosifolia, Neltuma alba y Pterogyne nitens. Desiccation tolerance was evaluated by decreasing the moisture content of the seeds to 4-5%. Storage behaviour was determined by storing dried seeds at -20, 5 and 20 °C for three, six and twelve months. The potential longevity of the seeds was estimated with an accelerated aging experiment. Response variable in all cases was the percentage of germinated seeds. The results indicated that the species have orthodox behaviour and can therefore be stored in seed banks. Throughout twelve months of storage the N. alba y P. nitens seeds remained dormant and had to be scarified to germinate. The potential longevity of the seeds allowed the species to be classified as short-lived (H. impetiginosus), intermediate-lived (J. mimosifolia y P. nitens), and long-lived (N. alba). The results will be useful to establish ex situ conservation strategies for these species, which should be complemented with in situ conservation actions. [ABSTRACT FROM AUTHOR]

Breeding goals for a dairy herd were developed by combining several of the traits of greatest economic impact on dairy farms; and a selection criterion based on the information available from genetic evaluations. A theoretical production system of 250 cows with a mean adult liveweight of 570 kg each, producing 5 000 L of milk, 173 kg of fat, and 163 kg of protein in 305 d was simulated. Feeding was based on grazing sown pastures, plus silage (maize and sorghum) and supplemental maize grain. The derivation of economic values of traits in the breeding goal was accomplished using a profit equation; and discounted expressions. Six scenarios were simulated by combining the proposed alternatives in concentrate feed costs {three levels: initial model (MI) (no change), MI + 20% and MI -20%} and product prices (two levels: ratios of protein/fat price of 1.33:1 and 2:1). Economic values generated by the base model were: - 0.045, 0.849, 1.412, and - 0.047 US$ kg-1 animal-1 for milk, fat, protein, and liveweight, respectively; they followed the same trend upon applying the remaining scenarios, and were sensitive to variations in costs and revenues. The selection index coefficients derived were -0.0477, 0.8317, and 1.4394 for additive genetic values of milk production, fat and protein, respectively. These coefficients were highly correlated with the objective under all six scenarios. [ABSTRACT FROM AUTHOR]

Cantaloupe melon (Cucumis melo L.) is the most important horticultural crop. However has not been established a nitrogen fertilization and soil moisture guidance for maintaining an adequate nutrimental state that relates with yield and fruit quality. In this research work, were studied the effect of four nitrogen doses fertilizations and three soil moisture levels on the foliar concentrations of eight plant nutrients and their relationship with yield and fruit quality. Findings showed that no statistical significant differences were observed between treatments on the foliar concentrations; with respect to the level nutrimental recommended for each one of nutrients, it was observed that N, P, K and Cu were inside the sufficiency level; while Mg, Mn and Fe were found in the interval for excessive level and Ca in the deficiency side. Fruit yield and quality were highly correlated with K concentration. In conclusion, findings let to know that foliar nutrient concentrations are not useful indicator for estimating yield and fruit quality, but they are for a management of nutrient and soil moisture that let the crop of the adequate levels.

Breast milk is changing with the progression of lactation and during a 24-h period. To determine the effect of diurnality or nocturnality on total nitrogen and protein content of the breast milk. We collected human milk samples from health mothers living throughout Community of Extremadura (Spain) from January 2008 to December 2008 with less than two months of lactation. We divided the samples in three groups: calostral group (1-5 days postpartum), transitional group (6-15 days postpartum) and mature group (> 15 days postpartum). All samples were stored in a freezer at -80°C. We considered as day period between 08:00-20:00h and night period 20:00-08:00h. Analysis of the human milk samples was based on the Kjeldahl method. Protein contents were calculated from total nitrogen x 6,25. The statistical analysis of the data was descriptive (mean ± standard deviation) and inferential (T-Student test). No differences (P > 0,05) were found to exist among the contents of individual human milk samples. The mean contents of each component were as follows: Total nitrogen of calostral, transitional and mature group was 0,30 ± 0,06 g/dL (night period), 0,29 ± 0,05 g/dL (day period); 0,26 ± 0,04 g/dL (night period), 0,25 ± 0,04 g/dL (day period); 0,22 ± 0,05 g/dL (night period), 0,20 ± 0,04 g/dL (day period) respectively, in this mature group with a statistical variation (P<0,05). Protein content of calostral, transitional and mature group was 1,88 ± 0,4 g/dL (night period), 1,81 ± 0,3 g/dL (day period); 1,62 ± 0,3 g/dL (night period), 1,59 ± 0,3 g/dL (day period); 1,35 ± 0,3 g/dL (night period), 1,26 ± 0,3 g/dL (day period) respectively, in this mature group with a statistical variation (P < 0,05). Although we observed differences in the nitrogen and protein content during the individual stages of lactation, it is just in the population of mature lactating women, where the components analyzed varied significantly between day and night.

Protease inhibitors have a great importance in biomedicine, diagnostic and biotechnology. Some micro- and nanotechnologies, such as intensity fading mass spectrometry and plasm on surface resonance, have allowed identification and further characterization of natural protease inhibitors. Their combination with dynamic light scattering and X-ray crystallography, allows obtaining nanometric details of protease-inhibitor complexes. [ABSTRACT FROM AUTHOR]

In this paper we describe the results obtained in the determination of some enzymatic activities and inhibitory activities against these enzymes in the mollusc Stylocheilus longicauda. Aqueous extracts were prepared from different parts of the animal (midgut gland, gonads and mantle). The extracts showed proteolytic activity at all assayed pH. The presence of pepsine and bromeline inhibitory activity was detected in all the extracts, being more remarkable for pepsina in the case of the mantle. Only the mantle and whole extracts showed acetylcholinesterasic activity but inhibitory activity against this enzyme was not detected in any case. Furthermore, the whole extract showed esterase and lipase activities. [ABSTRACT FROM AUTHOR]
