Deficiência de ferro: Conseqüências biológicas e propostas de prevenção

Iron deficiency is the commonest nutritional deficiency in the world. Although it affects adults, particularly women of reproductive age and during gestation, the most vulnerable group is children under two years of age. It affects mainly people living in developing countries, who have less access to balanced diets and health services and are exposed to precarious sanitary conditions. Iron deficiency has an impact on the immunity, adult work capacity and the cognitive development of children. Combating and preventing iron deficiency is one of the priorities in promoting public health. The strategies to achieve this end include the evaluation and correction of iron deficiency in pregnant women, the encouragement of breast feeding, oral iron supplementation in premature and newborn babies of low birth-weight, food enrichment and mobilization of the community.

Oxidação lipídica em peixes: mecanismo de ação e prevenção

Aquaculture produces food with high nutritive value, however its environmental conditions and management increase the stress reaction of fishes, prejudicing the quality of their products. The lipid oxidation is one of the main causes of the fishery deterioration, due the high unsaturated value of fatty acid of aquatic organisms. This review describes lipid oxidation mechanisms, their analysis methodology and some preventive ways, emphasizing the antioxidants effects of vitamin E utilization in fish's diet.

Período total de prevenção a interferência das plantas daninhas na cultura da alface cultivar Solaris

This research work aimed to determine the total period of interference of weeds prevention of lettuce cultivar Solaris. The experiment was conducted in Universidade Estadual de Londrina, in the period of autumn/ winter of 2008. The lettuce crop remained free from weed interference from emergence up to 0, 10, 20, 30, 40, 50 e 60 days. The experiment was arranged in a randomized block design with four replications. The weed community was composed by Bidens pilosa, Amaranthus hybridus, Oxalis corniculata, Euphorbia heterophylla, Spinacia oleracea, Commelina benghalensis e Lepidium virginicum. It was determined dry and fresh matter of weeds, and number of lettuce leaves. Assuming a tolerance of 5% for crop production decrease, it was verified that the total period of interference prevention (TPIP) occurred up to 21 days after transplanting. Weed interference throughout the crop cycle reduced 25% of its yield.

Danos do complexo broca-podridão à produtividade e à qualidade da cana-de-açúcar fertirrigada com doses de nitrogênio

The objective of this work was to evaluate the effect of nitrogen-fertigation on the damage caused by the borer-rot complex to the productivity and quality of fertigated sugarcane. The experiment was carried out in field, using a randomized complete block design, with four replicates and five N doses (0, 50 100, 150, and 200 kg ha-1) applied through drip irrigation. The following variables were determined: number of holes caused by Diatraea saccharalis (Lepidoptera: Crambidae); number of internodes infected with red rot; incidence percentage of red rot; stalk productivity; and sugar content. In laboratory, the attractiveness and the consumption of culm fragments by fourth instar caterpillars, in trials with or without choice, were evaluated. Nitrogen fertigation increased the incidence of D. saccharalis and red rot. The number of holes produced by the larvae was correlated with the occurrence of red rot. Sugar percentage reduced with the increase in the number of red rot affected internodes. Nitrogen doses did not affect the attractiveness of sugarcane culm fragments; however, higher N doses increased the consumption of these fragments by D. saccharalis caterpillars. Despite the damages to quality, nitrogen fertilization expressively enhanced the productivity of stalks and sugar.

Cloreto de sódio a 0,9%, adicionado ou não de dexametasona, intrapleural, na prevenção de aderências pulmonares após toracotomia intercostal em cães

Pulmonary adhesions in dogs are a common sequel after surgical intervention, undermining any interventions. This study aimed to determine in dogs, the efficacy of sodium chloride solution 0.9% with or without dexamethasone in order to prevent adhesions after intercostal thoracotomy. Fifteen dogs were separated into three groups of five animals, A, B and C and underwent thoracotomy in the fifth left intercostal space. Three other dogs were submitted to a previous study. In the dogs of Group A it was performed only a thoracotomy and thoracorraphy; in group B, it was performed a thoracotomy, thoracorraphy and injection into the pleural cavity of isotonic sodium chloride (10ml) and dexamethasone (1mg kg-1). In the dogs of the group C, it was performed the thoracotomy thoracorraphy and injected isotonic sodium chloride (10ml kg-1) into the pleural cavity. After 15 days of thoracotomy, it was performed transdiaphragmatic thoracocospy to determine the presence and score of adhesions between the lung and chest wall. The results demonstrated the presence of adhesions in the majority of group A and reduced or no adhesions in the other groups. For statistical evaluation, it was pplied the chi-square test with significance level of 5% (P≤0.05). The sodium chloride solution 0.9% with or without dexamethasone in the pleural space prevented or reduced lung adhesions after intercostal thoracotomy.
