13. Micronutrientes na gestação e lactação
Vitamina A, ferro e zinco são micronutrientes essenciais ao pleno funcionamento do organismo humano. Durante o período gestacional, seus requerimentos encontram-se aumentados devido ao intenso crescimento e proliferação celular e, durante a lactação, o leite materno constitui a mais importante fonte destes nutrientes para o recém-nascido e lactente.

14. A investigação da cegueira noturna no grupo materno-infantil: uma revisão histórica
Objetivou-se neste estudo apresentar uma revisão histórica sobre a cegueira noturna, um indicador funcional da deficiência de vitamina A. Realizou-se uma revisão da literatura científica publicada no período de 1929 a 2005, nas bases de dados Medline, Lilacs, SciELO e dos comitês nacionais e internacionais de saúde e de micronutrientes, utilizando-se

15. "Boro em mamoneira: Aspectos morfológicos e fisiológicos relacionados à deficiência e toxicidade" / Boron in castor bean plants: Morphologic and physiologic aspects related to the deficiency and toxicity
The castor bean production has highlighted as one of the most promising crops in cerrado and semi-arid farmlands, as the castor oil, besides being used in several industries, presents potential for biodiesel production. This work is based in the following hypotheses: a) the production of seeds and castor oil is related with appropriate supply of boron (B), a

16. Efeito da suplementação com retinol palmitato em codornas (Coturnix coturnx japonica) nos níveis de retinol na gema dos ovos
Vitamin A deficiency is a serious public health problem in developing countries, and it causes death and blindness among children in the developing countries. The fortification of food could be an important source of vitamins to control deficiency. 60 Coturnix coturnix japonica quails were used in a randomized design with duration of seven weeks. The birds w

17. Avaliação da aplicação de acido folico em tratamento aerobio de aguas residuarias. / Evaluation of application of folic acid in aerobic wastewater treatment .
They are deficiency of vitamins in sludge of biological wastewater treatment, especially the folic acid, that acts as micronutrient for certain bacteria and stimulating its growth. This work evaluated the effect of different concentrations of folic acid on the sludge in normal physiologic conditions and in endogenous respiration. The system was carried out b

18. Concentração de proteínas (fosvitina e lipovitelina) em gemas de ovos de galinhas (Gallus gallus) nos diferentes ciclos de postura e sua interferência na disponibilidade do ferro / Protein concentration (phosvitin and lipovitelin) in egg yolks of hens (Gallus gallus) in the different cycles of position and its interference in the availability of the iron
The egg is the product of efficient biological transformation made by the hens of position, with high nutricional quality for the human consumption. In the egg yolk of the egg it meets phosvitin called protein, the same one acts as hauled of the iron if binding it. The iron deficiency normally occurs due to the insufficient food consumption iron sources or l

19. Boron transport in Eucalyptus. 2. Identification in silico of a putative boron transporter for xylem loading in eucalypt
Boron (B) is a low mobility plant micronutrient whose molecular mechanisms of absorption and translocation are still controversial. Many factors are involved in tolerance to Boron excess or deficiency. Recently, the first protein linked to boron transport in biological systems, BOR1, was characterized in Arabidopsis thaliana. This protein is involved in boro

21. Micronutrients and Anaemia
Micronutrient deficiencies and anaemia remain as major health concerns for children in Bangladesh. Among the micronutrient interventions, supplementation with vitamin A to children aged less than five years has been the most successful, especially after distribution of vitamin A was combined with National Immunization Days. Although salt sold in Bangladesh i

22. Nitrogen Assimilation and Protein Synthesis in Wheat Seedlings as Affected by Mineral Nutrition. II. Micronutrients 1
Activity of nitrate reductase from Triticum aestivum L. seedlings was decreased by deficiencies of molybdenum, zinc, and chlorine. Nitrate accumulated in molybdenum-deficient seedlings, declined in zinc-deficient seedlings, and was unaffected by the other micronutrient treatments. Glutamic acid dehydrogenase activity was decreased by deficiency of molybdenum
