Assessment of the Correlation Between Insertion Torque and Resonance Frequency Analysis of Implants Placed in Bone Tissue of Different Densities

The primary stability of dental implants is fundamental for osseointegration. Therefore, this study aimed to assess the correlation between insertion torque (IT) and resonance frequency analysis (RFA) of implants placed in mandibles and maxillas of different bone densities. Eighty dental implants were placed in maxillas and mandibles, and IT and the implant stability quotient (ISQ) were measured at the time of implant insertion. Bone density was assessed subjectively by the Lekholm and Zarb index. The type I and II densities were grouped together (group A)as were the type III and IV densities (group B). The IT in group A was higher (Student t test, P = .0013) than in group B (46.27 +/- 18.51 Ncm, 33.62 +/- 14.74 Ncm, respectively). The implants placed in group A showed higher ISQ (Student t test, P = .0004) than those placed in group B (70.09 +/- 7.50, 63.66 +/- 8.00, respectively). A significant correlation between IT and the ISQ value was observed for group A (Pearson correlation test; r = 0.35; P = .0213) and for group B (r = 0.37; P = .0224). Within the limitations of this study, it was possible to conclude that there is a correlation between IT and RFA of implants placed in mandibles and maxillas of different bone densities.

Levantamento de raízes e tubérculos nos assentamentos rurais Araras I, II, III e IV, no município de Araras, SP

Com a disseminação da agricultura industrial, com grande utilização de insumos tecnológicos, mecanizada e fundamentada num número reduzido de espécies e variedades de plantas cultivadas, os modos de produção autóctone têm sofrido pressões em todo mundo. Entre estas, citam-se a modernização do campo, a perda de terras para agricultura comercial em larga escala e a emigração dos jovens em busca de melhores condições de vida, que acarretam grandes mudanças para estes sistemas agrícolas. As comunidades de agricultores de subsistência são detentoras de uma gama de variedades de diversas espécies cultivadas, sendo que essa diversidade é um fator adaptativo importante para o agricultor ante as variações ambientais, climáticas, biológicas e socioeconômicas, além de ser importante para a segurança do sistema alimentar mundial. Isto faz com que estes agricultores se tornem importantes parceiros para programas de conservação in situ de plantas cultivadas. No Brasil, assentamentos rurais são formados por agricultores de diversas origens, e são locais onde a agricultura é parcialmente voltada para a subsistência. Dentre a grande diversidade de plantas cultivadas para subsistência, as raízes e os tubérculos constituem, depois dos cereais, a principal fonte de alimento para a população humana. O presente estudo visou levantar as espécies de raízes e tubérculos cultivados nos Assentamentos Rurais Araras I, II, III e IV, no município de Araras, São Paulo, e analisou a potencialidade dos pequenos agricultores das assentamentos como mantedores de agrobiodiversidade. A pesquisa se deu através de entrevistas estruturadas e semi-estruturadas, onde os agricultores entrevistados forma selecionados de maneira aleatória e estratificada entre os quatro assentamentos. Os dados coletados foram analisados de maneira descritiva. Os resultados...(Resumo completo, clicar acesso eletrônico abaixo)

Cardiomyopathy and cell therapy: ejection fraction improvement and cardiac muscle mass increasing, after a year of bone marrow stem cells transplantation, by magnetic resonance image

The idiopathic dilated cardiomyopathy (IDC) is one of the major public health problems in the western world. Patients with IDC in functional class IV (New York Health Association - NYHA), even after therapeutic optimization, have high mortality. Stem cell therapy has emerged as a potential therapeutic option for cell death-related heart diseases and several positive effects were assigned to cell therapy in cardiomyopathy. The aim of this study was identify short-term result of cell transplantation in idiopathic dilated cardiomyopathy patients (IDC) who were treated by transplantation of autologous bone marrow mononuclear cells (BMMC). Intracoronary injections of autologous BMMC were performed in eight patients with severe ventricle dysfunction (mean of left ventricle ejection fraction – LEVF=20.03%), cardiac mass muscle around 156.2 g and NYHA between III and IV grades, other 8 IDC patients received placebo. The IDCs were followed - up for one and two years, by magnetic resonance imaging (MRI). The results after one year showed significant improvement in LVEF (mean=181.4) and muscle mass increasing (mean=181.4 g), after two years the LVEF continued improving, reaching a mean of 32.69% and the cardiac muscle mass kept stable (mean=179.4 g). Excepted for one patient, all the other had improvement in the NYHA functional class. The placebo group did not show any improvement. We believe that BMMC implant may be a beneficial therapeutic option for IDC patients.

Preparation and thermal decomposition of solid state lanthanide(III) and yttrium(III) chelates of ethylenediaminetetraacetic acid

Solid state chelates of general formula H[Ln(EDTA)] · nH2O (Ln = trivalent lanthanide (except for promethium) or yttrium; EDTA = ethylenediaminetetraacetate) were prepared. Thermogravimetry, differential thermal analysis. X-ray diffraction and complexometry were used to characterize and study the thermal stability and thermal decomposition of these compounds. © 1993.

Alcohol in cerebrospinal fluid (CSF) and alcoholism

Alcohol levels were measured in 15 cerebrospinal fluid (CSF) samples and 14 blood samples from grade III and IV male alcoholic patients with signs of nervous system involvement, and compared with levels detected in 11 CSF samples and 11 blood samples from abstemious patients or patients with grade I or II alcoholism whose CSF had been found to be normal by routine analysis (controls). Among the alcoholic patients, alcohol levels were lower in the CSF than in blood, whereas the opposite was true for the controls. The possible mechanisms underlying this difference are discussed and the need for further study of this topic is emphasized.
