ABSTRACT The obstacles in Phakopsora pachyrhizi management result especially from susceptible soybean genotypes and resistant fungal strains. The objective of the current study was to evaluate the applicability of the emission of extremely low and specific frequencies by Effatha technology in the soybean Asian rust control, nutrition, and its impact on yield. The in-vivo test followed the detached leaves method, with six treatments: frequencies 1 and 2 individually and in association; the conventional chemical treatment (fungicide azoxystrobin + benzovindiflupyr); and witnesses in presence and absence of the fungus. Frequency 1 relates to inhibition of the enzyme succinate dehydrogenase and 2 to ubiquinone oxidase. In the field, frequencies 1 and 2 associated (with the same fungicidal action of the in-vivo study); nutritional frequency; application of azoxystrobin + benzovindiflupyr + mancozeb, and control without application were evaluated. In vivo, the fungicide provided 85% control of the disease symptoms, against 65% of frequencies 1 and 2 in association, which showed a higher efficiency compared to the isolated frequencies. In the field, the rate of increase of symptoms were reduced by all treatments compared to the control. At the end of the soybean cycle, the conventional fungicide resulted in 33% severity against 56% of frequencies 1 and 2 associated, and 69.2% of the control. The emission of the frequency for increased nutrient efficiency stood out positively on yield in relation to all the other ones. The conventional application provided the highest weight of 1,000 grains, possibly a direct reflection of the better control of the disease.

ResumoObjetivoAlguns parâmetros clínicos de saúde periodontal foram avaliados comparativamente em pacientes que utilizavam braquetes convencionais e linguais.Material e métodoUm examinador treinado registrou as frequências de placa bacteriana visível (PB) e sangramento à sondagem (SS), bem como dos índices higiene oral simplificado (IHO-S) e gengival modificado (IGM), em 83 pacientes de duas clínicas. Os efeitos dos tratamentos ortodônticos na saúde periodontal foram analisados por regressão logística (α=0,05).ResultadoNo grupo convencional, a frequência de placa bacteriana foi significativamente mais elevada nas superfícies vestibulares dos dentes anteriores (OR = 12,5) e posteriores superiores (OR = 3,6), p < 0,01. O SS nos dentes posteriores também foi mais frequente neste grupo, p < 0,05. O grupo lingual apresentou frequência mais alta de placa bacteriana nas superfícies linguais dos dentes anteriores (OR = 4,3; p = 0,0034). O grupo convencional apresentou frequências significativamente elevadas de gengivite leve nas regiões vestibulares dos dentes anteriores (OR = 9,0) e posteriores superiores (OR = 16,7), p < 0,05, e de papilas anteriores (OR = 9,0 p = 0,0003). Por outro lado, o grupo lingual evidenciou gengivite leve mais frequentemente nas superfícies linguais dos dentes anteriores (OR = 54,5), p < 0,01.ConclusãoCom base nos resultados deste estudo, as condições clínicas de saúde periodontal podem ser consideradas razoáveis em pacientes que utilizavam braquetes convencionais e linguais.

AbstractObjectiveSome clinical periodontal health parameters were assessed comparatively in patients using conventional and lingual brackets.Material and methodA trained examiner registered the frequencies of visible plaque (VP), bleeding on probing (BOP), as well as the simplified oral hygiene (OHI-S) and modified gingival (MGI) indices in 83 subjects from two clinics. The effects of orthodontic treatments on periodontal health were analyzed using logistic regression (α = 0.05).ResultIn the conventional group, the frequency of visible plaque was significantly higher on the buccal surfaces of anterior (OR = 12.5) and maxillary posterior (OR = 3.6) teeth, p < 0.01. BOP in posterior teeth was also more frequent in this group, p < 0.05. The lingual group presented higher frequency of visible plaque on the lingual surfaces of anterior teeth (OR = 4.3; p = 0.0034). The conventional group had significantly higher frequencies of mild gingivitis in the buccal regions of anterior (OR = 9.0) and maxillary posterior (OR = 16.7) teeth, p < 0.05, and anterior papillae (OR = 9.0; p = 0.0003). On the other hand, the lingual group evidenced mild gingivitis more often in the lingual regions of anterior teeth (OR = 54.5), p < 0.01.ConclusionBased on the results of this study, the clinical periodontal health conditions may be considered acceptable for patients using both conventional and lingual brackets.

RESUMOObjetivou-se com o trabalho avaliar a influência do reflorestamento com essências nativas da Floresta Estacional Semidecidual, plantio de eucalipto e pastagem nos atributos químicos e físicos do solo de áreas degradadas. Foram selecionadas cinco áreas na bacia hidrográfica do Rio Aguapeí, na cidade de Garça, SP, sendo dois reflorestamentos com essências nativas, com 4 e 9 anos, um plantio de eucalipto, uma área de pastagem e um fragmento florestal utilizado como referência. O fragmento florestal apresentou a menor soma de bases e os maiores teores de P, Corg e CTC. Ele também apresentou a menor resistência à penetração, maior diâmetro e estabilidade dos agregados. Os atributos químicos e físicos do solo das áreas reflorestadas diferiram dos observados no fragmento florestal, mostrando que o período de recuperação não foi suficiente para restaurar esses atributos. Porém o reflorestamento com 9 anos melhorou significativamente nesses atributos do solo, tendendo a aproximar-se aos do fragmento florestal.

ABSTRACTThe objective with this study was to evaluate the influence of reforestation with native species from seasonal semideciduous forest, eucalyptus plantation, and pasture in the soil chemical and physical properties of degraded areas. Five sites were selected in the watershed of the Aguapeí River in the Garça city, Sao Paulo state: two reforestation areas with native species, with four and nine years old; a reforestation area with eucalyptus plantation, a pasture area, and a forest fragment used as control. The forest fragment presented the lowest exangeable bases and the highest levels of P, SOC and CEC; it also showed the lowest penetration resistance, and the largest diameter and aggregate stability. The chemical and physical soil attributes of the reforestation areas differed from those of the forest fragment (control), showing that the recovery period was not sufficient to restore these attributes. However, the 9-year-old reforestation area presented significant improvement of these soil attributes, tending to approach those of the control area.

BACKGROUND: In 2006 the Hematology Service of Hospital Maciel published its experience with peripheral blood progenitor cell harvesting for autologous stem cell transplantation using Filgen JP (Clausen Filgrastim). After mobilization with a mean filgrastim dose of 78 mcg/Kg, 4.7 x 10(6) CD34+ cells/Kg were obtained by apheresis. Age above 50, multiple myeloma as underlying disease and a malignancy that was not in remission were identified as frequent characteristics among patients showing complex mobilization. OBJECTIVE: The aim of this study was to compare stem cell mobilization using different brands of filgrastim. METHODS: One hundred and fifty-seven mobilizations performed between 1997 and 2006 were analyzed. This retrospective analysis comparative two groups of patients: those mobilized with different brands of filgrastim (Group A) and those who received Filgen JP (Clausen Filgrastim) as mobilizing agent (Group B). A cluster analysis technique was used to identify four clusters of individuals with different behaviors differentiated by age, total dose of filgrastim required, number of apheresis and harvested CD34+ cells. RESULTS: The mean total dose of filgrastim administered was 105 mcg/Kg, the median number of apheresis was 2 procedures and the mean number of harvested stem cells was 4.98 x 10(6) CD34+ cells/Kg. No significant differences were observed between Groups A and B regarding the number of apheresis, harvested CD34+ cells and number of mobilization failures, however the total dose of filgrastim was significantly lower in Group B. CONCLUSIONS: Among other factors, the origin of the cytokine used as mobilizing agent is an element to be considered when evaluating CD34+ cell mobilization results.

The plasma cell neoplasms may present in soft tissue as extramedullary plasmacytoma (EMP), in bone as a solitary plasmacytoma of bone (SPB), or as part of the multifocal disseminated disease multiple myeloma (MM). The EMP is rare, comprising around 3% of all plasma cell neoplasm. The majority (80%) occurs in the head and neck region. In this study we report a case of a man, 70 years old, melanoderm, with a lesion of the oral cavity. Upon physical examination, a lesion was found that extended throughout the posterior upper alveolar ridge, as far as the maxillary tuber on the left side, extending towards the palate. Radiographic examination, complementary laboratory exams were performed. Based on the conclusive symptoms of plasmacytoma, the patient was referred to the hematology service for treatment with local radiotherapy. The patient responded satisfactorily to the treatment, and after 15 months, all clinical symptoms of the lesion in the oral cavity had disappeared.

La neoplasia de células plasmáticas se presenta en los tejidos blandos como plasmocitoma extramedular (EMP), en el hueso como plasmocitoma solitario (SPB), o como parte de una enfermedad diseminada, el mieloma múltiple (MM). El EMP es poco frecuente, manifestandose en alrededor de un 3%. Se presentan generalmente (80%) en las regiones de cabeza y cuello. En este reporte de caso, un hombre de 70 años, melanoderma, presentaba una lesion en la cavidad oral. En el examen físico se observó la lesión a lo largo de la parte posterior del reborde alveolar superior, en la tuberosidad maxilar en el lado izquierdo hacia el paladar. Se realizaron exámenes radiográficos y de laboratorio. Con base en los signos de plasmocitoma, el paciente fue referido a tratamiento con radioterapia. El tratamiento fue muy exitoso y después de 15 meses se observó que el paciente no presentaba los signos clínicos característicos de la lesión neoplásica.
