1. The Effect of Olive Cake, with or Without Enzymes Supplementation, on Growth Performance, Carcass Characteristics, Lymphoid Organs and Lipid Metabolism of Broiler Chickens
ABSTRACT An experiment was carried out to investigate the effect of using olive cake (OC) in broiler diets, when it is supplemented with multi-enzymes or phytase enzyme. The OC was included in isocaloric, isonitorgneous diets at 5 and 10% levels and fed to broilers from 1-28 days of age. Experimental diets were fed with or without either of the two enzymes:

2. Waterlogging-induced changes in fermentative metabolism in roots and nodules of soybean genotypes
Waterlogging blocks the oxygen supply to the root system which inhibits respiration, and greatly reduces the energy status of cells that affect important metabolic processes. This study evaluated fermentative metabolism and carbohydrate contents in the root system of two soybean (Glycine max L. Merril) genotypes under hypoxic and post-hypoxic conditions. Nod

3. Seed vigor, antioxidant metabolism and initial growth characteristics of red rice seedlings under different light intensities
This work aimed to evaluate the effect that different intensities of light have on the physiological attributes of red rice seeds and seedlings. Before and after emergence, seedlings were exposed to light levels of 35%; 65% and 100% in a greenhouse. We evaluated shoots and roots, in terms of length and dry mass, as well as leaf area and content of chlorophyl

4. Efeito do tratamento tÃrmico e do Ãcido salicÃlico na atividade de polifenoloxidase, peroxidase e fenilalanina amÃnia-liase, nas caracterÃsticas fÃsico-quÃmicas e na incidÃncia de patÃgenos em morangos durante o armazenamento / Effect of heat treatment and salicylic acid on polyphenoloxidase, peroxidase and phenylalanine ammonia-liase activity, physical-chemistry characteristics and incidence of pathogens in strawberries during storage
The strawberry is a fruit that is highly perishable and are very susceptible to physical damage and fungal attack. The use of fungicides has been the primary method for reducing post-harvest diseases. Accordingly, alternative methods free of chemicals must be used in post-harvest to maintain the quality and prolong the life reduce the incidence of fungi. The

5. Influência da restrição calórica no metabolismo bioenergético e estado redox de Saccharomyces cerevisiaee Kluyveromyces lactis / Influence of caloric restriction on energy metabolism and redox state of Saccharomyces cerevisiaee Kluyveromyces lactis
Aging involves a progressive decline in metabolic efficiency of biological systems over time. Although it cannot be avoided, aging phenotypes are delayed in organisms undergoing caloric restriction, a dietary regimen consisting of a reduced availability of calories. The yeast Saccharomyces cerevisiae has proved to be an important model organism for studying

6. Effects of shade on the development and sugar metabolism of coffee (Coffea arabica L.) fruits.
Coffee fruits grown in shade are characterized by larger bean size than those grown under full-sun conditions. The present study assessed the effects of shade on bean characteristics and sugar metabolism by analyzing tissue development, sugar contents, activities of sucrose metabolizing enzymes and expression of sucrose synthase-encoding genes in fruits of c

8. Characterization of storage proteins, amino acid profile and enzymes involved in lysine metabolism in genetic modified barley (Hordeum vulgare L.) / Caracterização de proteínas de reserva, perfil de aminoácidos e enzimas envolvidas no metabolismo de lisina em cevada (Hordeum vulgare L.) geneticamente modificada
Cereals represent an important source of protein to human food and animal feed. However, they are characterized by low nutritional quality of proteins due to the unbalanced composition of amino acids, caused by the excess of the amino acids proline and glutamine and deficiency of lysine, threonine and tryptophan. The prolamin storage proteins constitute 50%

9. Phytotoxicity of cadmium and barium and derivation of critical limits in soils / Fitotoxidade de cádmio e bário e derivação de lilites críticos em solos
Soil pollution by heavy metals caused by anthropogenic activities is a problem in many countries. Cadmium (Cd) is one of the most hazardous elements due to its relatively high mobility in soils and transfer to plants. The main human exposure pathway to Cd is through the vegetable consumption and depends on the exposure scenario. Thus, defining a critical lim

10. A useful routine for biochemical detection and diagnosis of mucopolysaccharidoses
Mucopolysaccharidoses (MPS) constitute, owing to their biochemical, genetical and clinical characteristics, a large and heterogeneous subgroup among the lysosomal storage diseases (LSD). They are caused by deficiency of specific enzymes, which are responsible for glycosaminoglycan (GAG) breakdown during different steps of its degradation pathway. MPS are res

11. Purification and characterization of a carboxypeptidase and a dipeptidase from Tenebrio molitor (Coleoptera) larvae / Purificação e caracterização de uma carboxipeptidase e de uma dipeptidase da larva de Tenebrio molitor (Coleoptera)
Devido aos problemas, ambientais e à população humana, causados pelos inseticidas químicos, novas investigações para o controle de insetos tornaram-se necessárias. Para isto, um maior conhecimento sobre a fisiologia digestiva dos insetos torna-se essencial, visto que o intestino é uma interface, grande e relativamente desprotegida, entre o inseto e o

12. Mecanismo de defesa e recuperação da fotossintese em Centrolobium tomentosum sob condições de estresse induzido por SO2 / Mechanism of defense and recovery of photosynthesis in Centrolobium tomentosum under conditions of stress induced by SO2
Large quantities of gaseous pollutants emited by urban-industrial areas emit contribute to the degradation of ecosystems with subsequent declines in vegetation. The photosynthesis is one of the first processes altered by the action of these pollutants and sulphur dioxide (SO2), as one of the most common and harmful air pollutants, drastically affect the phot
