1. MODIFICAÇÃO QUÍMICA DA PECTINA DO MELÃO CAIPIRA (Cucumis melo VAR. ACIDULUS)
Melon is one of the most widely consumed fruits in the world. In Brazil, 60% of the production is for domestic consumption, with these fruits deemed to be of lower commercial value. For the first time, pectin has been extracted from this species of melon. So the extraction of this polysaccharide can be used as an alternative to increase the value of the frui

2. Estimativa de custos de três sistemas alimentares para a recria de novilhas acasaladas aos 18 meses de idade / Feeding systems costs for rearing beef heifers bred at 18 months of age
A idade ao acasalamento da novilha está relacionada com a eficiência econômica da produção de bovinos. A determinação de sistemas alimentares para a recria é fundamental para que as novilhas apresentem elevada taxa de prenhez. O objetivo deste trabalho foi estimar e avaliar os custos de alternativas alimentares na recria de novilhas de corte destinad

3. Participation of the endoplasmic reticulum protein chaperone thio-oxidoreductase in gonadotropin-releasing hormone receptor expression at the plasma membrane
Chaperone members of the protein disulfide isomerase family can catalyze the thiol-disulfide exchange reaction with pairs of cysteines. There are 14 protein disulfide isomerase family members, but the ability to catalyze a thiol disulfide exchange reaction has not been demonstrated for all of them. Human endoplasmic reticulum protein chaperone thio-oxidoredu

4. Estudos de genes envolvidos na via biossintética do antibiótico antitumoral Cosmomicina / Genes study envolved in biosynthetic pathway of antitumoral antibiotic Cosmomycin.
Cosmomycin is an antitumoral antibiotic produced by the soil bacteria Streptomyces olindensis DAUFPE 5622. Gene expression studies established that stress condition genes like dnaJ and 18hsp, and cosmomycin biosynthetic pathways genes are expressed under antibiotic production. Also the genes cosS and cosY (unknowns function), were selected and analyzed by bi

5. CAD e engenharia reversa como ferramentas de auxílio na fabricação de cartuchos para próteses ortopédicas
The manufacturing of above and below-knee prosthesis starts by taking surfac measurements of the patients residual limb. This demands the making of a cartridg with appropriate fitting and customized to the profile of each patient. The traditiona process in public hospitals in Brazil begins with the completion of a record file (according to law n388, of July

6. Literature, fine arts and cinema: correspondences and transformations in Clarice Lispector / Literatura, artes plásticas e cinema: correspondências e transformações em Clarice Lispector
The expression ut pictura poesis by Horaces Ars Poetica gave rise to the inter-relationship of the signs of arts. Hence, if relationships can be established between poetry and painting, likewise, there are some possible relationships amongst the literary text and other arts and medias. This study hypothesizes that similar cosmovisions express similar transla

7. Adenylyl cyclase types I and VI but not II and V are selectively inhibited by nitric oxide
Adenylyl cyclase (AC) isoforms catalyze the synthesis of 3',5'-cyclic AMP from ATP. These isoforms are critically involved in the regulation of gene transcription, metabolism, and ion channel activity among others. Nitric oxide (NO) is a gaseous product whose synthesis from L-arginine is catalyzed by the enzyme NO synthase. It has been well established that

8. Archetype JC Virus Efficiently Replicates in COS-7 Cells, Simian Cells Constitutively Expressing Simian Virus 40 T Antigen
JC polyomavirus (JCV), the causative agent of progressive multifocal leukoencephalopathy (PML), is ubiquitous in humans, infecting children asymptomatically and then persisting in the kidney. Renal JCV is not latent but replicates to excrete progeny in the urine. The renal-urinary JCV DNAs carry the archetype regulatory region that generates various rearrang

9. Molecular cloning of a CD28 cDNA by a high-efficiency COS cell expression system.
CD28 (Tp44) is a human T-cell-specific homodimer surface protein that may participate in T-cell activation. We have isolated a cDNA clone encoding CD28 by a simple and highly efficient cloning strategy based on transient expression in COS cells. Central to this strategy is the use of an efficient method to prepare large plasmid cDNA libraries. The libraries

10. Chromosome end formation in phage lambda, catalyzed by terminase, is controlled by two DNA elements of cos, cosN and R3, and by ATP.
The terminase enzyme of phage lambda is a site-specific endonuclease that nicks DNA concatemers to regenerate the 12 nucleotide cohesive ends of the mature chromosome. The enzyme's DNA target, cos, consists of a nicking domain, cosN, and a binding domain, cosB. cosB, situated to the right of cosN, comprises three 16 bp repeat sequences, R1, R2 and R3. A simi

11. In Vivo Regulatory Phosphorylation of Novel Phosphoenolpyruvate Carboxylase Isoforms in Endosperm of Developing Castor Oil Seeds1
Our previous research characterized two phosphoenolpyruvate (PEP) carboxylase (PEPC) isoforms (PEPC1 and PEPC2) from developing castor oil seeds (COS). The association of a shared 107-kD subunit (p107) with an immunologically unrelated bacterial PEPC-type 64-kD polypeptide (p64) leads to marked physical and kinetic differences between the PEPC1 p107 homotetr

12. Production and characterization of biologically active recombinant beta nerve growth factor.
DNA fragments encoding either rat or chicken beta nerve growth factor (NGF) were inserted in the expression vector p91023(B) for transient expression in COS cells. The two NGF constructs produced RNA transcripts and proteins of the predicted sizes. Conditioned media from the transfected cells stimulated neurite outgrowth from cultured chicken embryo sympathe
