age spectra of the two groups were plotted and analyzed; the attributions, similarities and differences of the main characteristic peaks from these two groups of serum Raman spectra were described. The SVM algorithm was combined with the normalized Raman spectroscopy data to identify the two groups of patient sera with 90% identification accuracy. This study shows that serum Raman spectroscopy combined with an SVM algorithm can be used for multiclass identification of hepatitis C. V.PURPOSE The aim of the present study was to establish an assessment regarding the efficacy of final disinfection protocols and sealers on the bond strength (BS) of root canal (RC) filling materials on root dentin which has already been treated with photobiomodulation (PBT) or photodynamic therapy (PBT) respectively. METHODS One-hundred and twenty root canals were included in the present study. The selected teeth were cleaned and shaped to accept the obturation. The prepared specimens were subjected to laser therapy (PBT and PDT) and were randomized into three groups (n = 20/group) on the basis of irrigation technique Group 1 distilled water (DW) + ultrasonic irrigation (UI); Group 2 17% EDTA; Group 3 0.2% Chlorhexidine digluconate (CHx) respectively. Each specific group was further divided into two subgroups (n = 10), based on endodontic sealing agent incorporated during obturation AH Plus or MTA Fillapex. The push-out test was used to gauge the BS, whereas the evaluation was done with the help of two-way ANOVA which was followed by a subsequent Tukey post-hoc test. The chi-square test was used to calculate the mode of failure in the selected specimens (α = 5%). RESULTS The final irrigation protocols of 17% EDTA and CHX helped to enhance the BS of RC filling material with either sealer agent used (p  less then  0.05), whereas, AH Plus reported an increase in the values of BS as compared to its counterpart, MTA Fillapex (p  less then  0.05). Increased values of cohesive failure were associated with all the groups, irrespective of the tested final irrigation protocols and RC sealer agents (p  less then  0.05). There was no significant difference between the laser therapies among all the groups (p  less then  0.05). CONCLUSIONS The use of 17% EDTA and CHX and sealing material AH Plus increased the BS of the obturation on radicular dentin previously subjected to either of the mentioned laser therapies. Furthermore, no significant effect on the BS was observed with the use of lasers in the study. V.Photodynamic antimicrobial chemotherapy (PACT) and photophysical properties of the photosensitizers are being actively studied as a possible alternative for antimicrobial agents. This study focuses on the application of neutral indium 5-p-carboxyphenyl-10-15-20-(tri-4-pyridyl)porphyrin and cationic indium 5-p-carboxyphenyl-10-15-20-(tris-4-methylpyridyl)-porphyrin triiodide conjugated to 6-mercapo-1-hexanol functionalized Ag/CuFe2O4 magnetic nanoparticles for photo-inactivation of S. aureus bacteria. Comparative studies were done on quaternized and unquaternized indium porphyrin complexes conjugated to Ag/CuFe2O4, where log reduction of 9.27 was obtained for quaternized conjugate and 0.83 for unquaternized conjugate. V.OBJECTIVES This study aimed to evaluate the reduction in bacterial of conventional endodontic treatment with and without antimicrobial photodynamic therapy (PDT) in primary teeth. METHODS Thirty primary anterior teeth with a diagnosis of pulp necrosis were selected. Patients were randomly allocated to two groups as follows Group I, patients undergoing conventional root canal therapy (n = 15) and Group II, patients undergoing conventional root canal therapy combined with antimicrobial PDT (n = 15). For PDT, methylene blue, at a concentration of 0.005%, was used as the photosensitizing agent, which was applied to the interior of the canal with a sterile paper cone for 3 min, followed by the administration of laser light for 40 s (wavelength 660 nm, energy density 4 J/cm², power 100 mW), delivered in direct contact at the entrance to the root canal. Two microbiological samples of the intra-canal content were taken (one before and one immediately after treatment in both groups) using paper cones. Clinical follow-up involved the investigation of fistulas and mobility and was performed 1- and 3 months after treatment. Data were statistically analyzed. RESULTS The reduction in bacterial load was 93% in Group I and 99% in Group II, with no statistically significant difference. CONCLUSIONS Conventional treatment combined with antimicrobial PDT with parameters used in this study proved effective but presented equal efficacious capability to conventional endodontic treatment alone. CLINICAL SIGNIFICANCE The use of PDT has been studied in endodontic treatment protocols in permanent teeth. However, clinical trials in deciduous teeth are necessary for establishign the effectiveness and parameters of this application. The present study analyzes the results of PDT in the endodontic treatment of deciduous teeth. learn more V.Exposure to endocrine-disrupting compounds (EDCs) during pregnancy can result in negative health effects in later generations, including sex changes and feminization. The present study assessed the feminization effects on male offspring rats of three EDCs Dienestrol (DIES), Linuron (LIN), and Flutamide (FLU). Sexually mature female rats were exposed from gestation day (GD) 6 until postnatal day (PND) 21 to 0.37, 0.75, 1.5, 3.12 or 6.25 μg/kg/day of DIES, 1.5, 3, 6, 12.5, 25 or 50 mg/kg/day of LIN, 3.5, 6.7, 12.5, 25 or 50 mg/kg/day of FLU, and the following mixtures FLU + DIES (mg/kg/day+μg/kg/day), 3.5 + 0.37, or 3.5 + 3, 25 + 0.37, or 25 + 3; FLU + LIN (mg/kg/day + mg/kg/day), 3.5 + 12.5, or 25 + 12.5; and DIES + LIN (μg/kg/day + mg/kg/day), 0.37 + 12.5, or 3 + 12.5. Anogenital distance (AGD), nipple retention (NR) and cryptorchidism were evaluated. FLU produced a decrease of AGD, an increase of NR, and an increase of cryptorchidism at the highest dose. None of these three endpoints were significantly affected by LIN or DIES treatments alone.
