International Journal of Morphology , 2012,
Abstract: The aim of this research was to evaluate the risk factors related to condylar resorption (CR) after orthognathic surgery. Was realized a systematic review with a search of the literature performed in the electronic databases PubMed, MedLine, Ovid, Cochrane Library for current evidence in the world literature as conducted, and relevant articles were selected in according to inclusion and exclusion criteria and the findings were compared. Eight papers, (follow-up 12 months to 69 months) were including. A sample of 2567 patient with mandible or bi maxillary surgery with an age range from 14 to 46 year old was observed. In 137 patients (5.3%) CR was observed , with a 97.6% (122) female. CR was related to 118 cases with mandibular deficiencies with high mandibular plane (advancement surgery). CR were present principally in bi maxillary surgery with a 103 cases (75.2%) and only two papers show any analysis to the relation with TMJ dysfunction. Current evidence in CR is poor but supports those female patients with mandibular deficiency and high mandibular plane angle submitted to bi maxillary surgery with change in occlusal plane (counterclockwise) are associated with condylar resorption after orthognathic surgery. El objetivo de esta investigación fue evaluar los factores de riesgo asociados a reabsorción condilar (RC) posterior a cirugía ortognática. Fue realizada una revisión sistemática con una búsqueda de la literatura realizada en bases de dato electrónicos como PubMed, MedLine, Ovid, Cochrane Library buscando actual evidencia en la literatura mundial; artículos relevantes fueron seleccionados según los criterios de inclusión y exclusión, comparando sus resultados. Ocho artículos (tiempo de seguimiento de 12 a 69 meses) fueron incluidos. Se observó una muestra de 2567 pacientes con cirugía mandibular o bimaxilar con una edad de entre 14 y 46 a os. En 137 pacientes (5,3%) se observó reabsorción condilar, siendo el 97,6% (122 casos) de sexo femenino. La RC fue observada n 118 casos de deficiencia mandibular con un plano mandibular alto (cirugía de avance mandibular). La RC estuvo presente principalmente en cirugías bimaxilares con 103 casos afectados (75,2%) y solo dos artículos evidenciaron análisis previo de disfunción de ATM. Actualmente la evidencia en RC es limitada pero fundamenta que mujeres con deficiencia mandibular y alto plano mandibular sometidas a cirugía bimaxilar con alteración del plano oclusal (giro horario) son asociadas a la reabsorción condilar después de la cirugía ortognática.

Abstract:

The main goal of this research was to evaluate the growth of nimblewill (Muhlenbergia schreberi), an emerging threat to forage grass. Our initial experiment was arranged in a completely randomized design, with 17 treatments (i.e., weeks) and 4 repetitions. Seventeen growth evaluations (i.e., treatments) were carried out every 7 days, totaling a 119-day cycle, followed by an analysis of the variables such as stolon number, length, number of leaves, dry matter, biological productivity, growth rate, and relative growth rate. A second experiment was conducted over a 5-week period to compare the growth variable between nimblewill plants and pastures. For all variables, the results showed that the weed grass developed slowly within the first 5 weeks after germination, indicating that this would be the best time to implement a chemical or cultural control measure. It was also observed that cultures with a rapid growth in the first 5 weeks after emergence could easily suppress weed growth. At the end of the experiment, stabilization of all variables was observed. However, additional observations are required to obtain more accurate results.

Abstract: Papaya has a wide geographical distribution, which demonstrates the great adaptability todifferent climatic conditions, being fruit from a tropical climate. Global climate change (GCC) scheduled for thecoming decades could alter the disease problems of papaya crop, so it is necessary and urgent to understand theimpacts of these diseases on the GCC in order to avoid them. This study aimed to analyze possible impacts onthe GCC black spot of papaya in Brazil, through the mapping of disease distribution made from the IPCCscenarios. The maps show a reduction in the favorable area for the disease in relation to both current climate forfuture scenarios (scenario A2 as for B2). The reductions in disease incidence will be more pronounced for the A2scenario than for the B2 scenario. This fact is probably related to the reduction in relative humidity to levels detrimental to the disease, ie to below 70% and average temperature rise above 27 ° C.O mamoeiro apresenta ampla distribui o geográfica, o que demonstra a grande capacidade deadapta o a diferentes condi es climáticas, sendo uma fruteira de clima tropical. As mudan as climáticasglobais (MCG) previstas para as próximas décadas poder o alterar os problemas fitossanitários da cultura domamoeiro, de modo que é necessário e urgente entender os impactos dessas MCG sobre as doen as de modo aevitá-los. O presente trabalho visou analisar possíveis impactos MCG sobre a pinta preta do mamoeiro no Brasil,através da elabora o de mapas de distribui o da doen a feitos a partir dos cenários do IPCC. Os mapasmostram redu o da área favorável à doen a em rela o ao clima atual para os cenários futuros (cenário A2eB2). As redu es na incidência da doen a ser o mais pronunciadas para o cenário A2 que para o cenário B2.Esse fato provavelmente está relacionado à redu o da umidade relativa média para níveis desfavoráveis àocorrência da doen a, ou seja, para valores abaixo de 70% e aumento da temperatura média acima de 27°C.

Abstract: The castor bean crop has shown great importance for the production of biodiesel, mainly forthe quality of its oil and not compete with food. The cultivation of castor oil is subject to attack by numerouspathogens, among which stands out the gray mold caused by Amphobotrys ricini. This affects the inflorescences,clusters and seeds, thus reducing production and oil content in fruits. Favourable climatic conditions for theoccurrence of gray mold in Brazil and the intensification of cultivation of castor beans, has helped to increase thedamage caused by this disease. The control of gray mold is based on the use of preventive measures, sincecurative measures are not effective or are unavailable until now. The use of resistant varieties, healthy seed, crop rotation, elimination of crop residues, the chemical treatment are among measures that can be employed in themanagement of A. ricini. Additionally, zoning areas of climate risk of occurrence of gray mold is a promisingalternative to be implemented in the program management of this disease. However, more studies are needed tounderstand the pathosystem castor - A. ricini to assist the development and adoption of new managementtechniques for this disease, as well as improve existing ones.A cultura da mamona tem demonstrado grande importancia para produ o de biodiesel,principalmente pela qualidade de seu óleo e por n o competir com a alimenta o humana. O cultivo da mamonaestá sujeito ao ataque de inúmeros patógenos, dentre os quais, destaca-se o mofo cinzento causado porAmphobotrys ricini. Este afeta as inflorescências, os cachos e as sementes, reduzindo assim a produ o e o teorde óleo nos frutos. As condi es climáticas favoráveis para ocorrência do mofo cinzento no Brasil e aintensifica o do cultivo da mamona, com a introdu o de cultivares altamente produtivas, tem contribuído parao aumento dos danos causados por esta doen a. O controle do mofo cinzento tem como base a utiliza o demedidas preventivas, uma vez que medidas curativas n o s o eficazes ou até o momento est o indisponíveis. Ouso de cultivares resistentes, sementes sadias, rota o de culturas, elimina o de restos culturais, tratamentoquímico das sementes s o algumas das medidas que podem ser empregadas no manejo da A. ricini. Contudo,mais estudos devem ser realizados para o entendimento do patossistema mamona - A. ricini a fim de auxiliar odesenvolvimento e a incorpora o de novas técnicas de manejo para esta doen a, bem como aprimorar asexistentes.
