25. Estudo dos mecanismos envolvidos no efeito do bisfosfonato alendronato dissÃdico na doenÃa periodontal experimental / Study of the mechanisms involved in effect of bisphosphonate dissodic alendronate in experimental periodontal disease
A periodontite, a principal causa de perda de dentes em adultos, Ã uma doenÃa inflamatÃria onde ocorre perda do osso alveolar e destruiÃÃo das fibras do ligamento periodontal. Tanto as bactÃrias periodontopatogÃnicas como os fatores provenientes do hospedeiro sÃo necessÃrios para o desenvolvimento e progressÃo desta patologia. Os bisfosfonatos cons

26. Influencia do treinamento fisico aerobio sobre as respostas cardiovasculares e respiratorias em mulheres na menopausa com e sem terapia de reposição hormonal
Menopause is a physiological condition in women?s life that occurs around the age of 45 to 52; it is responsible for progressive physical and psychological changes. These changes are generated by the reduction of progesterone and estrogen hormones and also modify the control of autonomic nervous system an the heart. The purpose of this study was to evaluate

27. Molecular cloning and expression of an Erwinia sp. gene encoding diphenyl ether cleavage in Escherichia coli.
A 2.1-kilobase fragment obtained by restriction enzyme HindIII digestion of Erwinia sp. genomic DNA was cloned into plasmid pUC19 and introduced into Escherichia coli by transformation. The transformants with diphenyl ether cleaving activity (Dpe+) were selected on agar plates with a specially designed medium (LTFN) containing 4-nitrodiphenyl ether. The posi

28. Repression of a Novel Isoform of Disproportionating Enzyme (stDPE2) in Potato Leads to Inhibition of Starch Degradation in Leaves But Not Tubers Stored at Low Temperature1
A potato (Solanum tuberosum) cDNA encoding an isoform of disproportionating enzyme (stDPE2) was identified in a functional screen in Escherichia coli. The stDPE2 protein was demonstrated to be present in chloroplasts and to accumulate at times of active starch degradation in potato leaves and tubers. Transgenic potato plants were made in which its presence w

29. Cometabolism of 1,1-Dichloro-2,2-Bis(4-Chlorophenyl)Ethylene by Pseudomonas acidovorans M3GY Grown on Biphenyl
1,1-Dichloro-2,2-bis(4-chlorophenyl)ethylene (DDE), a toxic breakdown product of 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (DDT), has traditionally been viewed as a dead-end metabolite: there are no published reports detailing enzymatic ring fission of DDE by bacteria in either soil or pure culture. In this study, we investigated the ability of Pseudomon

30. Cardiovascular effects of epinephrine and dipivalyl epinephrine applied topically to the eye in patients with glaucoma.
The cardiovascular effects of topical ophthalmological preparations of 2% epinephrine (EPI), 0.1% dipivalyl epinephrine (DPE), and placebo were studied in double-blind fashion in 20 patients with glaucoma. Both drugs and placebo produced a decrease in heart rate (2 +/- 3 beats/min) which, although small, was highly significant (p less than 0.001). Neither dr

32. Evidence for involvement of proteins HU and RpoS in transcription of the osmoresponsive proU operon in Escherichia coli.
Transcription of the proU operon of Escherichia coli is induced several hundred-fold upon growth at elevated osmolarity, but the underlying mechanisms are incompletely understood. Three cis elements appear to act additively to mediate proU osmoresponsivity: (i) sequences around a promoter, P1, which is situated 250 bp upstream of the first structural gene pr

33. Computational analysis of core promoters in the Drosophila genome
Candidate transcription start sites have been identified for about 2,000 Drosophila genes by aligning 5' expressed sequence tags (ESTs) from cap-trapped cDNA libraries to the genome. Examination of the sequences flanking these candidate transcription start sites revealed the presence of well-known core promoter motifs such as the TATA box, the initiator and

34. Sp1 and AP2 regulate but do not constitute TATA-less human TAFII55 core promoter activity
Human TAFII55 (hTAFII55), a component of the general transcription factor TFIID, is the only general transcription factor encoded by an intronless gene identified thus far. Analysis of the TATA-less hTAFII55 promoter-proximal sequence reveals putative binding sites for STAT-1, MEF2, E2F, Sp1, AP2, AREB6 and E47. Using chromatin immunoprecipitation, DNase I f

35. Molecular characterization of Xenopus laevis DP proteins.
It is widely believed that in mammalian cells the cellular transcription factor (DRTF1/E2F integrates cell-cycle events with the transcription apparatus by interacting with important regulators of the cell cycle, such as the retinoblastoma gene product (pRb) and related proteins, cyclins, and cyclin-dependent kinases. Here, we have defined DRTF1/E2F in Xenop

36. Functional interaction between DP-1 and p53.
The cellular transcription factor DRTF1/E2F and the tumor suppressor protein p53 play important roles in controlling early cell cycle events. DRTF1/E2F is believed to coordinate and integrate the transcription of cell cycle-regulating genes, for example, those involved in DNA synthesis, with the activity of regulatory proteins, such as the retinoblastoma tum
