Evaluation of fecal microorganisms of children with cleft palate before and after palatoplasty

This study isolated and quantified intestinal bacteria of children with cleft palate before and after palatoplasty. A prospective study was conducted from May 2007 to September 2008 on 18 children with cleft palate, aged one to four years, of both genders, attending a tertiary cleft center in Brazil for palatoplasty, to analyze the effect of surgical palate repair on the concentration of anaerobes Bacteroides sp, Bifidobacterium sp and microaerophiles Lactobacillus sp in feces of infants with cleft palate before and 24 hours after treatment with cefazolin for palatoplasty. There was significant reduction of Lactobacillus sp (p < 0.002), Bacteroides sp (p < 0.001) and Bifidobacterium sp (p = 0.021) after palatoplasty, revealing that surgery and utilization of cefazolin significantly influenced the fecal microbiota comparing collections before and after surgery. However, due to study limitations, it was not possible to conclude that other isolated factors, such as surgical stress, anesthetics and other medications used in palatoplasty might have a significant influence on the microbiota. Considering the important participation of the intestinal microbiota on both local and systemic metabolic and immunological activities of the host, professionals should be attentive to the possible influence of these changes in patients submitted to cleft repair.

Assessment of chemokine serum levels in epithelial ovarian cancer patients

Aims and background. The study was undertaken to investigate CCL2/MCP-1, CCL3/MIP-l alpha, CCL4/MIP-1 beta, CCL5/RANTES and CXCL8/IL-8 women with epithelial ovarian cancer.Methods and study design. Sixteen patients diagnosed with epithelial ovarian cancer and 18 healthy women with no evidence of malign neoplasia (control group) aged from 23 to 89 years (mean +/- SEM, 58.7 +/- 2.3) were included. The epithelial ovarian cancer patients underwent laparotomy and debulking surgery Chemokines serum levels were measured by cytometric bead array. Statistical analysis was performed using Mann-Whitney and Kendall's tau. P <0.05 was considered statistically significant for all analyses.Results. The tumor staging (FIGO) was classified into: I in 4 cases (25%), III in 5 cases (31.3%) and stage IV in 7 cases (43.8%). Sera chemokine dosages of CCL2 /MCP-1 and CCL4/MIP-1 beta were lower in epithelial ovarian cancer patients than in the control group (P = 0.021 and P = 0.030, respectively). No significant difference between groups was observed in the levels of CCL3/MIP-l alpha, CCL5/RANTES and CXCL8/IL-8. No association between the chemokines analyzed and tumor stage was found. The serum level of CCL4/MIP-1 beta was correlated with CA-125.Conclusions. The study of serum levels of CCL2/MCP-1, CCL3/MIP-l alpha, CCL4/MIP-1 beta, CCL5/RANTES and CXCL8/IL-8 chemokines in epithelial ovarian cancer patients identified a down-regulation in CCL2/MCP-1 and CCL4/MIP-1 beta, which suggests that the two chemokines may play an important role in the pathophysiology of ovarian cancer.

Thermal study of the solid-state reactions on Pt-15%Rh/Hg system

Thermogravimetry (TG), energy dispersive X-ray microanalysis (EDX), scanning electron microscopy (SEM), mapping surface and X-ray diffraction (XRD) were used for the study of solid-state reaction on Pt-15%Rh with electrodeposited mercury. The results suggest when heated the mercury film react with the Pt-15%Rh alloy to form intermetallics having different thermal stabilities indicated by three mass loss steps. The first mass loss step occurs between room temperature and 184 degrees C only the bulk Hg is removed and PtHg4, PtHg2 and RhHg2 were characterized by XRD. The second step, between 184 and 271 degrees C, was attributed to PtHg4 decomposition with formation of PtHg2 stabilized by RhHg2. The third step, between 271 and 340 degrees C, was attributed to decomposition of a solid-solution of PtHg2/RhHg2. The fourth step, between 340 and 600 degrees C, was ascribed to: (1) a thermal decomposition of PtHg2, formed by a PtHg eutectoid reaction (similar to 340 degrees C) on the surface and (2) Hg removal from a solid solution of Pt-15%Rh(Hg).
