13. Physico-chemical and sensorial characteristics of rice (Oryza sativa L.) irradiated and the effect in Sitophilus oryzae L. development / Características físico-químicas e sensoriais do arroz (Oryza sativa L.) irradiado e o efeito no desenvolvimento de Sitophilus oryzae L.
Rice is exposed to injuries especially due to the attack of insects, which represent great qualitative and quantitative losses. The aim of the present research was to verify the viability of the gamma irradiation as rice (Oryza sativa L.) conservation method; its efficiency in the control of an important pest for stored grains Sitophilus oryzae L. and the ef

14. Desenvolvimento das plantas, ocorrência de insetos, produção e conservação de frutos de goiabeiras sob adubações orgânica e mineral / Plant development, insect incidence, fruit yield and conservation of guava fruits under organic and mineral fertilization
The influence of mineral fertilizers and organic compost on the development of guava trees, fruit yield, insect incidence and fruit post-harvest conservation was evaluated. Also, the effects of different doses of mineral fertilization (ammonium sulphate and potassium chloride) and organic compost was studied by supplying proportions of the recommended dose (

15. Variation in either the physical and mechanical properties and the quality of the bean (Phaseolus vulgaris L.) during the drying process and storage / Variação das propriedades físicas e mecânicas e da qualidade do feijão (Phaseolus vulgaris L.) durante a secagem e o armazenamento
There is a lack of information in the available literature on the changes that may occur in the bean during the drying process and storage time. Thus, the accomplishment of studies that would generate theoretical and practical information about a better conservation of the product are really relevant. So, this work was carried out to analyze several characte

16. Estabilidade da entomofauna num mosaico de plantação de eucalipto e áreas naturais de conservação. / Stability of the entomofauna in a region composed by eucalypt plantations and conservation areas.
A partir da grande expansão da área de florestas plantadas no Brasil nas últimas décadas, vem ocorrendo uma grande pressão ambientalista e governamental por estudos de avaliação e de monitoramento ambiental de empreendimentos florestais. Por outro lado, as próprias empresas florestais vêm preocupando-se com a estabilidade das florestas plantadas, co

17. Evolutionary conservation of apoptosis mechanisms: Lepidopteran and baculoviral inhibitor of apoptosis proteins are inhibitors of mammalian caspase-9
We cloned a new inhibitor of apoptosis protein (IAP) homolog, SfIAP, from Spodoptera frugiperda Sf-21 cells, a host of insect baculoviruses. SfIAP contains two baculovirus IAP repeat domains followed by a RING domain. SfIAP has striking amino acid sequence similarity with baculoviral IAPs, CpIAP and OpIAP, suggesting that baculoviral IAPs may be host-derived

18. The nonstructural glycoprotein of rotavirus affects intracellular calcium levels.
Rotavirus infection of monkey kidney cells has been reported to result in a significant increase in the concentration of intracellular calcium. This increase in intracellular calcium was associated with viral protein synthesis and cytopathic effects in infected cells. We tested the effect of individual rotavirus proteins on intracellular calcium concentratio

19. Conservation of neural nicotinic acetylcholine receptors from Drosophila to vertebrate central nervous systems.
Nicotinic acetylcholine receptors (nAChR) are found both in vertebrate and insect central nervous systems. We have isolated a Drosophila gene by crosshybridization with a vertebrate probe. Structural conservation of domains of the deduced protein and of intron/exon boundaries indicate that the Drosophila gene encodes an nAChR alpha-like subunit (ALS). That t

20. Conservation of a functional hierarchy between mammalian and insect Hox/HOM genes.
We have generated several transgenic Drosophila strains containing different mouse Hox genes under heat shock control and studied how their generalized expression affects Drosophila larval patterns. We find that they have spatially restricted effects which correlate with their genetic order and expression pattern in the mouse; as they are expressed more post

21. Evolutionary conservation and predicted structure of the Drosophila extra sex combs repressor protein.
The Drosophila extra sex combs (esc) protein, a member of the Polycomb group (PcG), is a transcriptional repressor of homeotic genes. Genetic studies have shown that esc protein is required in early embryos at about the time that other PcG proteins become engaged in homeotic gene repression. The esc protein consists primarily of multiple copies of the WD rep

22. Expression of the major capsid protein VP6 of group C rotavirus and synthesis of chimeric single-shelled particles by using recombinant baculoviruses.
VP6 of group C (Cowden strain) rotavirus was expressed in the baculovirus system. The recombinant protein, expressed to a high level in insect cells, was purified by ion-exchange chromatography. The purified protein was proven to be trimeric. The effect of pH on the trimer's stability was investigated. Coexpression of VP6 from group A (bovine strain RF) and

23. Autographa californica Nucleopolyhedrovirus orf69 Encodes an RNA Cap (Nucleoside-2′-O)-Methyltransferase
The AcNPV orf69 gene encodes a protein that contains an S-adenosylmethionine (AdoMet)-dependent methyltransferase signature motif. More significantly, ORF69 shows high conservation at residues diagnostic for (nucleoside 2′-O)-methyltransferase activity. To analyze the function of this protein, which was renamed MTase1, it was overexpressed in Escherichia c

24. Molecular cloning of cDNA for double-stranded RNA adenosine deaminase, a candidate enzyme for nuclear RNA editing.
We have cloned human cDNA encoding double-stranded RNA adenosine deaminase (DRADA). DRADA is a ubiquitous nuclear enzyme that converts multiple adenosines to inosines in double-helical RNA substrates without apparent sequence specificity. The A --> I conversion activity of the protein encoded by the cloned cDNA was confirmed by recombinant expression in inse
