Clareamento para dentes despolpados: revisão de literatura e considerações

The esthetics of the teeth is not a privilege of our days, because concerns in that effect have been reported since 1860. Faced with an endodontically treated tooth that presents any type of color change, professionals can use intracoronary bleaching, which is more conservative attempt to restore the normal color of teeth. Bleaching aims to remove pigments by oxidizing agents and for that, various techniques were developed. Among the risks of tooth whitening the external resorption is the most severe, which occurs when the whitening penetrates through the dentin tubules to the periodontal ligament and initiates an inflammatory response. To prevent external resorption is required to place an intracoronal bleaching barrier. It is important to know the time between the bleaching treatment for restoring procedure for getting a good sealing to prevent microleakage. This study aims to review the literature about the different types of bleaching agents and their risks.

Acute phase response following ovariohysterectomy in female dogs

The concentrations of acute phase proteins are correlated with the severity of the surgical trauma, being elevated when severe tissue injury is produced. The aim of this study was to evaluate the leukogram and the acute phase proteins concentrations in healthy female dogs submitted to minimally invasive ovariohysterectomy, with the use of nylon cable ties (G1), and conventional (laparotomy) ovariohysterectomy, with the use of nylon suture (G2), as methods to ligate the ovarian pedicles and uterine body, respectively. Blood samples from 30 adult healthy female dogs (15 for each group) were obtained before surgery, and at 24 and 48 h and 7 days after surgery. Serum protein fractions were determined by means of sodium dodecyl sulfate polyacrylamide gel electrophoresis. Neutrophilia was observed 24 h after both surgical procedures but did not differ (P ≥ 0.05) between the groups. In G1, the estimated concentration of ceruloplasmin increased (P ≤ 0.05) 48 h after the surgical procedure. The estimated ceruloplasmin concentration was significantly higher in G1 (P ≤ 0.05) when compared to G2 48 h postoperatively, and the estimated haptoglobin concentration was also significantly greater in G1 (P ≤ 0.05) than in G2 from 24 h to 7 days after surgery. Through the ceruloplasmin and haptoglobin estimated concentrations, we conclude that the minimally invasive ovariohysterectomy caused a more intense inflammatory response, which was not reflected in the white blood cell count.

Functional XPB/RAD25 redundancy in Arabidopsis genome: characterization of AtXPB2 and expression analysis

The xeroderma pigmentosum complementation group B (XPB) protein is involved in both DNA repair and transcription in human cells. It is a component of the transcription factor IIH (TFIIH) and is responsible for DNA helicase activity during nucleotide (nt) excision repair (NER). Its high evolutionary conservation has allowed identification of homologous proteins in different organisms, including plants. In contrast to other organisms, Arabidopsis thaliana harbors a duplication of the XPB orthologue (AtXPB1 and AtXPB2), and the proteins encoded by the duplicated genes are very similar (95% amino acid identity). Complementation assays in yeast rad25 mutant strains suggest the involvement of AtXPB2 in DNA repair, as already shown for AtXPB1, indicating that these proteins may be functionally redundant in the removal of DNA lesions in A. thaliana. Although both genes are expressed in a constitutive manner during the plant life cycle, Northern blot analyses suggest that light modulates the expression level of both XPB copies, and transcript levels increase during early stages of development. Considering the high similarity between AtXPB1 and AtXPB2 and that both of predicted proteins may act in DNA repair, it is possible that this duplication may confer more flexibility and resistance to DNA damaging agents in thale cress.

Leucogram and serum acute phase protein concentrations in queens submitted to conventional or videolaparoscopic ovariectomy

Trinta gatas, saudáveis, foram submetidas à ovariectomia pela técnica convencional e por videolaparoscopia. Amostras de sangue foram obtidas com o objetivo de verificar a intensidade da resposta inflamatória por meio da análise das concentrações de proteinas de fase aguda e contagem de leucócitos antes e até 144 horas após procedimento cirúrgico. As proteínas que apresentaram aumento significativo 24 horas após a cirurgia foram: ceruloplasmina, hemopexina, haptoglobina e α1-glicoproteína ácida, 69,8%, 103,5%, 117,3% e 199,0%, respectivamente, para ovariectomia convencional, e 22,3%, 46,1%, 79,8% e 74,6%, respectivamente, para ovariectomia por videolaparoscopia. A resposta inflamatória foi mais evidente nas gatas submetidas à ovariectomia convencional. Os resultados mostram aumento e diminuição na concentração de proteínas de fase aguda e na contagem de leucócitos, podendo ser utilizados na avaliação da resposta inflamatória induzida por procedimentos cirúrgicos.
