Fonseca, José Maria Aranha;Campos, Ana Luiza Morais;Arras López, José Ramón Rodriguez;
Jornal Brasileiro de Psiquiatria , 2007, DOI: 10.1590/S0047-20852007000400008
Abstract: repetitive behavior, stereotypies and restricted interests are some of the main symptoms that compound the asperger?s disorder. however, until what point is possible to differentiate them from obsessive-compulsive symptoms that meet criteria for obsessive-compulsive disorder (ocd)? many times, that?s not possible. this work reports the case of a patient with asperger syndrome and ocd. we bring up until what point is really important the distinction of ocd as a comorbidity different from asperger, and also our therapeutic conduct, in which high doses of a selective serotonin reuptake inhibitor - ssri - (fluoxetine) was fundamental to a better socio-occupational adjustment of the patient, significantly improving his quality of life.

Lessa, Fernanda Campos Rosetti;Aranha, Andreza Maria Fábio;Hebling, Josimeri;Costa, Carlos Alberto de Souza;
Brazilian Dental Journal , 2010, DOI: 10.1590/S0103-64402010000100004
Abstract: this study evaluated the cytotoxic effects of 2 mineral trioxide aggregate (mta) cements - white-mta-angelus and a new formulation, mta-bio - on odontoblast-like cell (mdpc-23) cultures. twenty-four disc-shaped (2 mm diameter x 2 mm thick) specimens were fabricated from each material and immersed individually in wells containing 1 ml of dmem culture medium for either 24 h or 7 days to obtain extracts, giving rise to 4 groups of 12 specimens each: g1 - white-mta/24 h; g2 - white-mta/7 days; g3 - mta-bio/24 h; and g4 - mta-bio/7 days. plain culture medium (dmem) was used as a negative control (g5). cells at 30,000 cells/cm2 concentration were seeded in the wells of 24-well plates and incubated in a humidified incubator with 5% co2 and 95% air at 37oc for 72 h. after this period, the culture medium of each well was replaced by 1 ml of extract (or plain dmem in the control group) and the cells were incubated for additional 2 h. cell metabolism was evaluated by the mtt assay and the data were analyzed statistically by anova and tukey's test (α=0.05). cell morphology and the surface of representative mta specimens of each group were examined by scanning electron microscopy. there was no statistically significant difference (p>0.05) between g1 and g2 or between g3 and g4. no significant difference (p>0.05) was found between the experimental and control groups either. similar cell organization and morphology were observed in all groups, regardless of the storage periods. however, the number of cells observed in the experimental groups decreased compared to the control group. mta-bio presented irregular surface with more porosities than white-mta. in conclusion, white-mta and mta-bio presented low cytotoxic effects on odontoblast-like cell (mdpc-23) cultures.

Aranha, Andreza Maria Fábio;Giro, Elisa Maria Aparecida;Hebling, Josimeri;Lessa, Fernanda Campos Rosetti;Costa, Carlos Alberto de Souza;
Journal of Applied Oral Science , 2010, DOI: 10.1590/S1678-77572010000500006
Abstract: this in vitro study evaluated the cytotoxicity of an experimental restorative composite resin subjected to different light-curing regimens. methods: forty round-shaped specimens were prepared and randomly assigned to four experimental groups (n=10), as follows: in group 1, no light-curing; in groups 2, 3 and 4, the composite resin specimens were light-cured for 20, 40 or 60 s, respectively. in group 5, filter paper discs soaked in 5 μl pbs were used as negative controls. the resin specimens and paper discs were placed in wells of 24-well plates in which the odontoblast-like cells mdpc-23 (30,000 cells/cm2) were plated and incubated in a humidified incubator with 5% co2 and 95% air at 37oc for 72 h. the cytotoxicity was evaluated by the cell metabolism (mtt assay) and cell morphology (sem). the data were analyzed statistically by kruskal-wallis and mann-whitney tests (p<0.05). results: in g1, cell metabolism decreased by 86.2%, indicating a severe cytotoxicity of the non-light-cured composite resin. on the other hand, cell metabolism decreased by only 13.3% and 13.5% in g2 and g3, respectively. no cytotoxic effects were observed in g4 and g5. in g1, only a few round-shaped cells with short processes on their cytoplasmic membrane were observed. in the other experimental groups as well as in control group, a number of spindle-shaped cells with long cytoplasmic processes were found. conclusion: regardless of the photoactivation time used in the present investigation, the experimental composite resin presented mild to no toxic effects to the odontoblast-like mdpc-23 cells. however, intense cytotoxic effects occurred when no light-curing was performed.

An Analysis of the Spectral Energetics for a Planet Experiencing Rapid Greenhouse Gas Emissions  [PDF]
André Ferreira Aranha, José Augusto P. Veiga
Atmospheric and Climate Sciences (ACS) , 2017, DOI: 10.4236/acs.2017.71009
Abstract: So far, energetics studies related to climate change have focused on the disturbed and undisturbed kinetic and potential energies, as well as their transformations, without dealing with the energetics involved in the phenomena of different spatial scales. Thus, the present work reports the first analysis of the spectral energetics for a condition of climate change, followed by the high-range emission scenario, RCP8.5, which originated from the new Max Planck Institute Earth System Model (MPI-ESM). The results showed that both types of generation (Go and Gn), baroclinic processes (Co and Cn), kinetic energies (Ko and Kn) and the barotropic process, Mn, significantly increase in the condition of a warming climate. Moreover, the results still reveal that in the most components of the energetics, is the planetary scale waves that are the most impacted under a climate change scenario. These results highlight that global warming can have different impacts on particular types of motions.

Lessa, Fernanda Campos Rosetti;Aranha, Andreza Maria Fabio;Nogueira, Indri;Giro, Elisa Maria Aparecida;Hebling, Josimeri;Costa, Carlos Alberto de Souza;
Journal of Applied Oral Science , 2010, DOI: 10.1590/S1678-77572010000100010
Abstract: chlorhexidine gluconate (chx) is recommended for a number of clinical procedures and it has been pointed out as a potential cavity cleanser to be applied before adhesive restoration of dental cavities. objective: as chx may diffuse through the dentinal tubules to reach a monolayer of odontoblasts that underlies the dentin substrate, this study evaluated the cytotoxic effects of different concentrations of chx on cultured odontoblast-like cells (mdpc-23). material and methods: cells were cultured and exposed to chx solutions at concentrations of 0.06%, 0.12%, 0.2%, 1% and 2%. pure culture medium (α-mem) and 3% hydrogen peroxide were used as negative and positive control, respectively. after exposing the cultured cells to the controls and chx solutions for 60 s, 2 h or 60 s with a 24-h recovery period, cell metabolism (mtt assay) and total protein concentration were evaluated. cell morphology was assessed under scanning electron microscopy. chx had a dose-dependent toxic effect on the mdpc-23 cells. results: statistically significant difference was observed when the cells were exposed to chx in all periods (p<0.05). significant difference was also determined for all chx concentrations (p<0.05). the 60-s exposure time was the least cytotoxic (p<0.05), while exposure to chx for 60 s with a 24-h recovery period was the most toxic to the cells (p<0.05). conclusion: regardless of the exposure time, all chx concentrations had a high direct cytotoxic effect to cultured mdpc-23 cells.
