Tomate salada: uma alternativa como fonte de antioxidante para uso tópico

Tomato Salad: An Alternative as Antioxidant Source for Topic Use. Tomato is the principal source of lycopene, a carotenoid with high antioxidant activity which can be used topically as a phytocosmetic to combat skin aging. The aim of this study was to get a lycopene-rich extract from salad tomato pulp. The extract was analyzed using UV/vis spectroscopy, thin layer chromatography and high performance liquid chromatography. Oxidant activity was analyzed using the free radical DPPH method. The presence of lycopene in the salad tomato was confirmed. It was present in the apolar fraction rich in carotenoids, which was 96.70% lycopene. In the evaluation of the antioxidant activity, using the radical DPPH, the extract showed activity (IC(50) = 0,311 mg/mL). We conclude that the salad tomato can be used as a source of antioxidants for topic use.

Sementes de guandu, produzidas em semeadura tardia: efeito de doses de fósforo, potássio e espaçamentos

The objective of this work was to evaluate the effects of five P(2)O(5) rates and four K(2)O rates in two inter row plant spacings on the quality of short-duration pigeonpea seeds, in Selviria, Mato Grosso do Sul State, Brazil. For determining the treatments effects, a completely randomized block design was used, in a 2x5x4 factorial with four replicates, with the following treatments: 30 and 50 cm plant inter row spacings, 0, 40, 80, 120 and 160 kg ha(-1) of P(2)O(5) and 0, 30, 60 and 90 kg ha(-1) of K(2)O. Evaluations of first germination count, germination speed, germination, accelerated aging and seedlings field emergence were conducted. The fertilization of P(2)O(5) was positive, tip to the 120 kg ha, I-ate. The fertilization of K(2)O was positive for first count, accelerated aging, and seedlings field emergence.

TRAIL-R3-related apoptosis: Epigenetic and expression analyses in women with ovarian neoplasia

Objective. To assess the expression of TRAIL-R3 and the methylation of a CpG island within the TRAIL-R3 promoter both in cystadenoma tumors and primary and metastatic epithelial ovarian carcinoma (EOC).Methods. RNA was obtained from women with normal ovarian (NO) tissues (n = 18), ovarian serous cystadenoma tumors (n = 11) and EOC (n = 16) using Trizol (R). Quantitative PCR (gRT-PCR) was performed to quantify the relative levels of TRAIL-R3. The methylation frequency of the CpG island in the TRAIL-R3 promoter was assessed using the methylation-specific PCR (MSP) assay after DNA bisulfite conversion. The differences between the groups were evaluated using the chi-square, Student's t, ANOVA, Mann-Whitney U, Wilcoxon or Kruskal-Wallis tests as indicated. The survival rates were calculated using the Kaplan-Meier method.Results. Cystadenoma and metastatic EOC tumors expressed significantly more TRAIL-R3 mRNA than primary EOC tumors. Methylation of the TRAIL-R3 promoter was absent in NO tissues, while hemimethylation of the TRAIL-R3 promoter was frequently found in the neoplasia samples with 45.4% of the cystadenoma tumors, 8.3% of the primary EOC samples and 11.1% of the metastatic EOC samples showing at least partial methylation (p = 0.018). Neither the expression of TRAIL-R3 nor alterations in the methylation profile were associated to cumulative progression-free survival or the overall survival in EOC patients.Conclusions. Primary EOC is associated to a lower TRAIL-R3 expression, which leads to a better understanding of the complex disease and highlighting potential therapeutic targets. Promoter DNA methylation was not related to this finding, suggesting the presence of other mechanisms to transcriptional control. (C) 2012 Elsevier B.V. All rights reserved.

Respiratory muscular strength decrease in children with mylomeningocele

Study Design. Case-control study.Objective. To evaluate respiratory muscle force in children with myelomeningocele. Summary of Background Data. Myelomeningocele is a common spinal cord malformation with limitations linked to central nervous system lesions and abnormalities in respiratory movements. Despite this, little attention has been given to evaluating respiratory muscle force in these patients.Methods. Children with myelomeningocele aged between 4 and 14 years ( myelomeningocele group; MG, n = 20) were studied and compared with healthy children ( control group; CG, n = 20) matched for age and gender. Respiratory muscular force was evaluated by maximum inspiratory ( Pimax) and expiratory ( Pemax) pressures.Results. Groups were similar for age [ CG = 8 ( 6 - 13) = MG = 8 ( 4 - 14), P > 0.05]; gender, and body mass index [ CG = 17.4 ( 14.1 - 24.7) x MG = 19.2 ( 12.6 - 31.9), P > 0.05]. The lumbosacral region was predominantly affected ( 45%). Maximum respiratory pressures were significantly higher in CG than MG ( Pimax = CG: similar to 83 +/- 21.75 > MG: -54.1 +/- 23.66; P < 0.001 and Pemax = CG: + 87.4 +/- 26.28 > MG: + 64.6 +/- 26.97; P = 0.01). Patients with upper spinal lesion ( UL) had lower maximum respiratory pressure values than those with lower spinal lesion ( LL), [Pimax ( UL = - 38.33 +/- 11.20 cm H2O x LL = - 60.85 +/- 24.62 cm H2O), P < 0.041 and Pemax ( UL = + 48 +/- 20.82 cm H2O x LL + 71.71 +/- 26.73 cm H2O), P = 0.067]).Conclusion. Children with myelomeningocele at the ages studied presented reduced respiratory muscle force with more compromise in upper spinal lesion.

Use of a cyanoacrylate ester adhesive for splinting of replanted teeth

This paper reports a case of tooth replantation in which the splinting was performed with stainless steel orthodontic wire and a widely marketed brand of quick-setting cyanoacrylate ester adhesive (Super Bonder((R))). The long-term clinical and radiographic success of the case reported in this paper indicates that the splinting technique using a quick-setting cyanoacrylate ester adhesive may be a feasible option for making a rapid, simple and efficient contention of replanted teeth in situations where the routinely used materials are not readily available.
