Brazilian Oral Research , 2005, DOI: 10.1590/S1806-83242005000300010
Abstract: the goal of this study was to evaluate skeletal, dental and chronological development in an hiv-positive group of children, as compared with a control group, during a four-year period. panoramic radiographs and hand and wrist radiographs of 60 children were taken. the children, of both sexes, aged 5 years and 2 months to 15 years and 5 months, were selected as follows: 30 hiv-positive volunteers who had acquired the disease vertically, and 30 volunteers who did not present the hiv infection or any other systemic disease. all radiographs were technically standardized and analyzed according to criteria established by nolla (dental age), greulich and pyle (bone age), and ekl?f and ringertz (bone age). the results were submitted to student's t-test at a 5% level of significance. based on the comparison between the chronological age and the dental or the skeletal age, significant differences were observed between hiv-positive and hiv-negative children, both in 1999 and in 2003 (p < 0.05). considering the results obtained with the methodology used, it was concluded that hiv-positive children of both sexes presented delayed bone development despite the administration of antiretroviral drugs, and that hiv-positive female children presented younger dental ages compared with their chronological ages in 1999 and in 2003; and hiv-positive males, in 1999.

Oliveira, Marília Gerhardt de;Morais, Luciano Engelmann;Silva, Daniela Nascimento;Oliveira, Helena Willhelm de;Heitz, Cláiton;Gai?o, Lêonilson;
Journal of Applied Oral Science , 2009, DOI: 10.1590/S1678-77572009000300007
Abstract: objectives: this study evaluated the agreement of computed tomography (ct) imaging using 3d reformations (3dr) with shaded surface display (ssd) and maximum intensity projection (mip) in the diagnosis of bone changes in mandibular condyles of patients with rheumatoid arthritis (ra), and compared findings with multiplanar reformation (mpr) images, used as the criterion standard. material and methods: axial ct images of 44 temporomandibular joints (tmjs) of 22 patients with ra were used. images were recorded in dicom format and assessed using free software (imagej). each sample had its 3dr-ssd and 3dr-mip results compared in pairs with the mpr results. results: slight agreement (k = 0.0374) was found in almost all comparisons. the level of agreement showed that 3dr-ssd and 3dr-mip yielded a number of false-negative results that was statistically significant when compared with mpr. conclusions: 3dr-ssd or 3dr-mip should only be used as adjuvant techniques to mpr in the diagnosis of bone changes in mandibular condyles.

Braun, Ana Paula;Grassi Soares, Clarissa;Glüer Carracho, Helena;Pereira da Costa, Nilza;Bauer Veeck, Elaine;
Journal of Applied Oral Science , 2008, DOI: 10.1590/S1678-77572008000200010
Abstract: this study evaluated the optical density of two microfilled and two microhybrid resins, as well as the composition of these materials with regard to their optical density. cavities prepared in 12 2-mm- or 4-mm-thick acrylic plastic plates were filled with z250 (3m-espe), a110 (3m-espe), charisma (heraeus-kulzer) and durafillvs (heraeus-kulzer). the resin increments (2-mm-thick) were light-cured for 40 s. three 0.12-s radiographic exposures were made of each #2 acrylic plastic plate. denoptix system optical plates were used to obtain the digital images. three readings of the composite resin surface were made in each radiograph, totalizing 216 readings. the mean of highest and lowest grey-scale values was obtained. two specimens of each composite resin were prepared for sem analysis of the chemical elements related to optical density, using energy dispersive x-ray analysis (edx). the results were subjected to shapiro-wilk's test, anova, tukey's test at 1% level of significance and pearson's correlation. the mean grey-scale values at 2 mm and 4 mm were: z250 = 154.27a and 185.33w; a110 = 46.77b and 63.05y; charisma = 163.40c and 200.46z; durafillvs = 43.92b and 58.99x, respectively. pearson's test did not show any positive correlation between optical density and percentage weight of optical density chemical elements. it was concluded that the microhybrid resins had higher optical density means than the microfilled resins; among the evaluated resins, charisma had the highest optical density means.
China’s Grain Production under Bottom-up and Top-down Patterns of Agricultural Reforms: A Typical Case Study in Anhui Province
Wei Shui,Gregory Veeck
Journal of Geography and Geology , 2012, DOI: 10.5539/jgg.v4n2p22
Abstract: By reviewing the changes in China’s agricultural reforms since 1978 from the perspective of its initiator, guide, designer and organizer, the author defines two stages of agricultural reforms: one is the bottom-up stage in early 1980s and the other is the top-down stage after China’s entry into WTO. With a comprehensive quantitative-qualitative analysis of grain production of Anhui Province in response to the full implementation of the bottom-up and top-down agricultural reforms, conclusions are drawn as follows: 1) grain production growth has made great contributions to solving China’s grain food crisis during the bottom-up agricultural reform as well as to China’s grain food security at the top-down reform stage; 2) in general, among all sorts of socioeconomic factors, arable land, chemical fertilizers and mechanization have exerted the most significant influence on grain yield; 3) in contrast, chemical fertilizers and irrigation played the most critical role in early 1980s, followed by arable land and mechanization, while at the stage of the top-down agricultural reform, the main influencing factors include arable land, mechanization, chemical fertilizers and irrigation in sequence; 4) along with the increasing trend of agricultural specialization and clustering after the entry into WTO, irrigation and mechanization have made less contribution to grain production growth, while chemical fertilizers have been under the law of diminishing returns; 5) natural disasters including serious droughts and floods have been playing a special role in the stagnation and fluctuation of grain growth. Currently, with the leadership of government and the participation of peasants themselves, the negative influences exerted by natural disasters have been relieved a lot.
