    ANDRADE, A.K.P.; FEIST, I.S.; CAI, S.; PANNUTI, C.; ZEZELL, D.M. ; DE MICHELI, G.. Bacterial reduction in class II furcation after root debridment with or without Nd:YAG laser irradiation. Brazilian Dental Journal, v. 15, Special issue, p. 90-91, 2004.

    Abstract: The use of Nd:Yag laser for bacterial reduction as an adjuvant to nonsurgical periodontal treatment has been approached in several studies. Furcation complex anatomy is responsible for comprised treatment results in this areas due to the lack of proper access for instrumentation showing the persistence of a pathogenic microbial flora. The purpose of this clinical trial, randomized, double-blinded was to evaluated the bacterial reduction achieved with the Nd:YAG associated to conventional treatment on furcation sites of patients with chronic periodontitis. In a split mouth design study, 34 class II furcations that were selected from 17 patients with chronic periodontitis. They received previous full mouth periodontal treatment, except for the experimental sites. The 17 furcations of the Control group underwent twice manual and ultrasonic root debridment in weekly intervals. The Test group received the same treatment as the Control group followed by the Nd:YAG laser application (100mJ/pulse; 1.5W; 15Hz; 60sec). The microbiological parameters total numbers of anaerobic Colony Forming Units(CFU); Black pigmented CFU and the level of Actinobacillus actinomycetemcomitans(Aa), Porphyromonas gingivalis (Pg) and Prevotella intermedia(Pi) were determined at baseline, immediatly and one month after the treatment. The results showed a significant reduction of total CFU for both groups immediately after the treatment, but it was better for the Test group. After one month the total CFU average increased but was still below pretreatment levels for both groups. The black pigmented CFU and the level of Aa, Pg e Pi decreased significantly after the treatment but 30 days after there was an increase almost equal to baseline levels for both groups. The Nd:Yag laser associated with convencional treatment promoted bacterial reduction on class II furcation immediately after its application.

    MARTINI, G.A. ; VIVEIROS, W.; QUINAGLIA, G.; FERREIRA, M.L.; ROGERO, S.O. ; ROGERO, J.R. . Blyes and fet: a preliminary understanding between effects and total estrogenic activity on surface waters. Applied Research in Toxicology, v. 2, suppl. 1, p. 43-43, 2017.

    Abstract: Endocrine disrupting chemicals (EDCs) are included in a range of substances and are present in practically all environmental matrices, generally at low concentrations. For the occurrence evaluation of these substances, several in vitro tests are employed, among of them Bioluminescent Yeast Estrogen Screening (BLYES), which measures the total estrogenic activity in EEQ. However, this assay is not able to provide information about adverse effects to aquatic organisms. In order to observe aquatic communities effects, organic extracts of surface water samples from rivers and reservoirs of São Paulo state with results above the detection limit in BLYES (> 0.1 EEQ) were performed with embryonic assays with Danio rerio. The methodology was conducted according OECD 236, to verify acute effects such as: absence of heart beats, absence of somites, no tail detachment and coagulated embryo. Embryonic malformations were evaluated, such as: reduction of organism size, cardiac and vitelline edema, spine curvature and reduction of heart beating, which are characteristics of chronic effects. Among the 21 tested samples, 24% showed acute effects for Danio rerio and 14%, chronic effects. The effects observed probably would be associated with EDCs and/or other contaminants that may bind to the receptor in BLYES assay. The information obtained by embryonic assay with Danio rerio was suitable to show the effects of these groups of contaminants of the organic extracts and would complement the BLYES response. Accomplishing tests to evaluate effects on embryo reproductive system to establish a correlation between estrogenic activity and acute and chronic effects observed on FET is necessary.

    Abstract: The modality, known as brachytherapy, was performed in Brazil by only a hand full of hospitals at an extremely high cost. For producing new sources, five major areas must be considered: 1) source production: nuclear activation and/or radiochemical reaction; 2) welding; 3) Quality control: leakage tests; 4) Dosimetry and metrology; 5) Operational procedures; 6) validation studies. To perform all steps, a multidisciplinary team works together to overcome difficulties. - Iridium-192 pellets: In Brazil there are 140 machines with pellets that replacement every 5 years. Our new production line has assembly, welding and quality control hot cells. - Iridium-192 wires: Produced since 1999. The wire is activated at IPENs IEA-R1 reactor for 30 hours with 5x1013 n/cm-2.s-1 neutron flux resulting in 192 mCi maximum activity. - Iridium-192 seed: New seed for ophthalmic cancer treatment. The irradiation device presented 90% activity homogeneity. We are still testing in-vivo. - Iodine-125 seeds: Largely used in low dose brachytherapy. I-125 binding yield achieved with our new reaction was 80%; Laser welding presented 70% efficiency. Approved in all leakage tests. - Other ongoing projects: Veterinary brachytherapy, Waste management, Radionecrosis healing with laser, calibrations sources production, linear accelerator calculations for hospitals, sources with polymeric matrix Our Iodine-125 seeds will be available in 2018. All other projects are advancing. We will continue to develop new products hoping to help the Brazilian population fight against cancer. For producing new sources, five major areas must be considered: 1) source production: nuclear activation and/or radiochemical reaction; 2) welding; 3) Quality control:eakage tests; 4) Dosimetry and metrology; 5) Operational procedures; 6) validation studies.

    SCAGLIUSI, SANDRA R. ; CARDOSO, ELIZABETH C.L. ; LUGAO, ADEMAR B. . Butyl rubber recycling by means of gamma radiation followed by mechanical shear. International Journal of Waste Resources, v. 8, p. 53-54, 2018. DOI: 10.4172/2252-5211-C1-011

    Abstract: Polymeric materials (plastics and rubbers) cover a continuously raising proportion of urban and industrial solid wastes discarded in landfills and consequently their impact on environment are more and more concern. Rubbers exhibit a very slow natural decomposition due to their chemical structure weather resistant as well to enzymatic degradation and to microorganisms. Rubber recovering is hampered by its insolubility caused by crosslinked structures. Besides, this tridimensional structure causes various problems for material recovering and reprocessing. Just 8% to 12% of polymeric residues are thermoplastic polymers; remaining are elastomers especially post consumption tires. It is relevant to emphasize that the crosslinking is essential for practical use of rubber and this process is worldwide known as vulcanizing process, discovered by North American Charles Goodyear. The implementation of new technologies in order to reduce polymeric residues, acceptable from the environmental viewpoint and at an effective cost proved to be a great problem due to inherent complexities for polymers reuse. Ionizing radiation has capacity to change structure and properties of polymeric materials. Butyl rubbers have been used in wide scale within a variety of applications such as tires spare-parts and diverse artifacts. Major effect of high energy photon, such as gamma rays in butyl and halo-butyl rubbers is the creation of free radicals accompanied by changes in mechanical properties. This work aims to the development of processes of controlled degradation (de-vulcanizing) of butyl rubber in order to characterize their availability for modification and changes of their properties. Experimental results obtained showed that butyl rubbers irradiated at 25 kGy and further sheared can be used as the starting point for mixtures with pristine rubber.

    KUCHAR, NIELSEN G. ; ZAMATARO, CLAUDIA B. ; RABELO, THAIS ; JUVINO, AMANDA ; ZANINI, NATHALIA ; CASTRO, PEDRO ; ZEZELL, DENISE M. . Calcium analysis of gamma sterilized human dentin submmited to Er,Cr:YSGG laser irradiation. Photobiomodulation, Photomedicine, and Laser Surgery, v. 37, n. 10, p. A18-A19, 2019. DOI: 10.1089/photob.2019.29013.abstracts

    Abstract: Studies report that gamma radiation changes the oral cavity of patients submitted to radiotherapy. These changes include xerostomia, resulting in an unsaturation of calciumand phosphate in the oral cavity. However, human enamel samples isolated from the altered oral environmentwhen irradiatedwithgamma radiation at doses of up to 25kGy (much higher than radiotherapy doses) were shown to have undergone no changes in molecular hardness or micro surface. After approval of the Research Ethics Committee, 20 human dentin samples were evaluated before and after irradiation, split randomly into control group (n = 10) and irradiated group (n = 10) treated with 25.0 kGy at the Co60 multipurpose irradiator and irradiated with Er,Cr:YSGG laser in the parameters: 8.5 J/cm2 in the Fourier Transform Infrared Spectroscopy (FTIR), % surface Microhardness loss and Scanning Electron Microscopy (SEM). At the end, acidic biopsies were performed to quantify the concentration of calcium present in the samples. In the results of FTIR analysis differences were found only in the bands of organic content and in the inorganic content, difference were not found between before and after irradiations. The EDS and % Surface Microhardness loss analysis corroborates these findings, as well as no significant loss of the Calcium content before and after their radiation with Co60 at 25 kGy and with the Er,Cr:YSGG laser. These findings lead us to a new hypothesis of behavior of the hydroxyapatite crystal submitted to the gamma irradiation.

Carbohydrate composition and site-occupancy determination in pituitary and recombinant preparations of human thyrotropin. Journal of Biotechnology, v. 256, suppl., p. S15-S15, 2017. DOI: 10.1016/j.jbiotec.2017.06.053

    Abstract: Human thyrotropin (hTSH) is a glycoprotein with three potential glycosylation sites: two in the -subunit and one in the -subunit. Carbohydrate site-occupancy is frequently neglected in glycoprotein characterization, even if related to folding, trafficking, initiation of inflammation, host defence and congenital disorders of glycosylation (CDG). For the first-time N-glycoprofiling analysis was applied to site-occupancy determination of two native pituitary hTSH, in comparison with three CHO-derived preparations of hTSH, a widely used biopharmaceutical. A single methodology provided: (i) average N-glycan mass; (ii) mass fraction of each monosaccharide and of sulfate; (iii) percent carbohydrate. The results indicate that occupancy (65–87%) and carbohydrate mass (12–19%) can be 34–57% higher in recombinant hormones. The average glycan mass is 24% lower in pituitary hTSH and contains ∼3-fold fewer moles of galactose (P < 0.005) and sialic acid (P < 0.01). The number of moles of fucose per mole of hTSH was found 2.5-fold higher in the pituitary preparations. One of these native preparations, presenting the smallest glycan mass, lowest occupancy, GalNAc, sulfate, Gal and sialic acid contents, also presented the lowest in vivo bioactivity and circulatory half-life. This methodology, extremely important for comparing a recombinant biopharmaceutical to its native equivalent, can be applied to any physiologically or clinical relevant glycoprotein.

    Abstract: Melanin pigmentation is the result of melanin granules produced by melanocytes present in the basal layer of the oral epithelium. Gingival physiological melanin pigmentation is symmetric and persistent, may cause esthetic problems especially in individuals with a gummy smile. Various techniques have been described for the removal of melanin pigmentation from the gingival epithelium and partial thin connective tissue, as chemical agents, cryosurgery, surgery and gingival grafts. Recently, lasers systems have been used to coagulate and vaporize cells, promoting controlled gingival ablation. This study compares clinical efficiency to removal gingival melanin pigmentation in 20 patients with dioxide carbon laser, and 20 patients with cold scalpel during 30 days after surgery. A dioxide carbon laser (output = 5W; superpulse = 0,5s; spot size = 2,5mm defocused; focal distance = 5,5cm, Intensity = 102 W/cm2) was irradiated on gingival mucosal surface. Both techniques presented epithelialization in 15 days. Both systems are considered effective for removal melanin pigments. Patient's evaluation with postoperative pain found the carbon dioxide laser technique superior to the cold scalpel one. After 30 days, the repigmentation occured in 45% of the dioxide carbon laser patients, and 80% of the cold scalpel patients.

    SUZUKI, L.C.; YAMADA JUNIOR, A.M. ; HAYEK, R.R.A.; RIBEIRO, M.S. . A case report of photodynamic therapy on bacterial reduction before immediate implant. Brazilian Dental Journal, v. 15, Special issue, p. 127-127, 2004.

    Abstract: Recent studies have demonstrated that a number of oral bacteria can be killed by photodynamic therapy with low concentrations of dyes. Photodynamic therapy is the combination of light with appropriate wavelength and a photosensitizer. The antimicrobial activity is mainly mediated by singlet oxygen and/or free radicals generated by the photoactivated sensitizer. A flap surgery aiming an immediate implant was made in a residual root with periodontal lesion on upper first premolar. After the extraction, a microbiological sample with sterile paper points was harvested. Then, the photosensitizer was applied in the infected alveolus and irradiated with low-intensity laser, ?= 660 nm, P= 30 mW and E= 9 J . After the photodynamic therapy, a new microbiological sample was harvested. Subsequently, it was prepared the implant bed with conical burs and then the implant was placed. Patient was medicated with antibiotic after surgery. The microbiological analysis showed a significant reduction of Prevotella sp., Fusobacterium sp. and Streptococcus beta-hemoliticus. This finding suggests that photodynamic therapy is an alternative method to disinfect alveolus before implant placement. Therefore, this study highlights the need for future work in the area of photodynamic therapy to reduce bacteria without harming host tissue.
