Otimização de um método cromatográfico de análise de pesticidas organoclorados em amostras de peixes

Considering that persistent organic pollutants (POPs) including synthetic substances belonging to differents organic functions, including organochlorine pesticides (OCPs), which are the most persistent and bioaccumulative, with high toxicity to humans and animals. Accordingly environmental and biological monitoring is necessary, in order to have greater control regarding the irresponsible use of these products. Though there are several analytical methodology reported in the literature to make determinations of this pesticide, they present some difficulties, requiring several steps to make the clean up of the sample. The proposed project aims to optimize a new analytical method that allows to perform the extraction of organochlorine pesticides in fish tissues, employing acetone as solvent assisted by ultrasound bath, making the method more quickly and not requiringfurther steps to purify the sample. Were analyzed the recoveries of pesticides in study in samples of tilapia average values: Heptachlor=84,7±9,8%; Aldrin=87,3±3,5%; Endosulfan=101,4±18,6%; DDE= 90,5± 3,3%, Endrin=102,2±13,8%., DDD=92,1±19,9%; DDT=90,8±6,8%. The real samples showed values granted for our legislation and low values of error

Usefulness of vaginal cytology tests in women with previous hysterectomy for benign diseases: assessment of 53,891 tests

Objective. To assess the value of vaginal screening cytology after hysterectomy for benign disease.Methods. This cross-sectional study used cytology audit data from 2,512,039 screening tests in the metropolitan region of Campinas from 2000 to 2012; the object was to compare the prevalence of abnormal tests in women who had undergone a hysterectomy for benign diseases (n = 53,891) to that of women who had had no hysterectomy. Prevalence ratios (95% confidence intervals, 95% Cl) were determined, and chi-square analysis, modified by the Cochrane-Armitage test for trend, was used to investigate the effects of age.Results. The prevalence of atypical squamous cells (ASC), low-grade squamous intraepithelial lesion (LSIL), and high-grade squamous intraepithelial lesion or squamous-cell carcinoma (HSIL/SCC) was 0.13%, 0.04% and 0.03%, respectively, in women who had undergone hysterectomy, and 0.93%, 0.51% and 0.26% in women who had not undergone hysterectomy. The prevalence ratios for ASC, LSIL and HSIL/SCC were 0.14(0.11-0.17), 0.08 (0.06-0.13) and 0.13 (0.08-020), respectively, in women with a hysterectomy versus those without. For HSIL/SCC, the prevalence ratios were 0.09 and 029, respectively, for women <50 or >= 50 years. The prevalence rates in women with a previous hysterectomy showed no significant variation with age.Conclusion. The prevalence rates of ASC, LSIL and HSIL/SCC were significantly lower in women with a previous hysterectomy for benign disease compared with those observed in women with an intact uterine cervix. This study reinforces the view that there is no evidence that cytological screening is beneficial for women who have had a hysterectomy for benign disease. (C) 2015 Elsevier Inc.

Straight and angulated abutments in platform switching: influence of loading on bone stress by three-dimensional finite element analysis

PURPOSE: In view of reports in the literature on the benefits achieved with the use of platform switching, described as the use of an implant with a larger diameter than the abutment diameter, the goal being to prevent the (previously) normal bone loss down to the first thread that occurs around most implants, thus enhancing soft tissue aesthetics and stability and the need for implant inclination due to bone anatomy in some cases, the aim of this study was to evaluate bone stress distribution on peri-implant bone, by using three-dimensional finite element analysis to simulate the influence of implants with different abutment angulations (0 and 15 degrees) in platform switching. METHODS: Four mathematical models of an implant-supported central incisor were created with varying abutment angulations: straight abutment (S1 and S2) and angulated abutment at 15 degrees (A1 and A2), submitted to 2 loading conditions (100 N): S1 and A1-oblique loading (45 degrees) and S2 and A2-axial loading, parallel to the long axis of the implant. Maximum (σmax) and minimum (σmin) principal stress values were obtained for cortical and trabecular bone. RESULTS: Models S1 and A1 showed higher σmax in cortical and trabecular bone when compared with S2 and A2. The highest σmax values (in MPa) in the cortical bone were found in S1 (28.5), followed by A1 (25.7), S2 (11.6), and A2 (5.15). For the trabecular bone, the highest σmax values were found in S1 (7.53), followed by A1 (2.87), S2 (2.85), and A2 (1.47). CONCLUSIONS: Implants with straight abutments generated the highest stress values in bone. In addition, this effect was potentiated when the load was applied obliquely.
