Abstract: Três experimentos foram realizados para estudar o desempenho e a digestibilidade dos nutrientes e determinar os níveis de enzimas endógenas em suínos na fase de recria, alimentados com ra es suplementadas com enzimas exógenas. A ra o experimental foi constituída de milho, farelo de soja, vitaminas e minerais mais a adi o de enzimas exógenas. A mistura consistiu de 25 g de enzima exógena por 100 kg de ra o. A composi o básica das ra es foi 18,00% proteína bruta (PB) e 3400 kcal/kg de energia digestível (ED). No experimento 1, foram utilizados 160 leit es mesti os Landrace x Large White de 9,87±1,48 kg de peso vivo, distribuídos em cinco tratamentos (controle ou dieta basal; DB + amilase; DB + lipase; DB + protease; e DB + complexo de amilase, lipase e protease) e oito repeti es; as variáveis estudadas foram consumo de ra o diário médio (CRDM), ganho de peso diário médio (GPDM) e convers o alimentar (CA). No Experimento 2, foram utilizados 20 leit es machos castrados de 17,4±0,5 kg, mantidos em gaiolas metabólicas e em ambiente controlado; as variáveis estudadas foram ED, energia metabolizável (EM) e coeficiente de digestibilidade da proteína bruta (CDPB). Este experimento consistiu dos cinco tratamentos acima, com duas repeti es. No Experimento 3, foram utilizados 30 leit es, com o objetivo de estudar os níveis de enzimas digestivas endógenas. O delineamento experimental utilizado nos três experimentos foi de blocos casualizados. Os resultados n o revelaram efeitos da adi o de enzimas exógenas sobre o CRDM e GPDM, porém, a adi o de protease melhorou a CA em nível significante. Os resultados mostraram que a adi o de enzimas exógenas também influiu no CDPB, apesar de n o ter sido observada diferen a para a digestibilidade da energia digestível. Os níveis de enzimas endógenas nos suínos n o foram influenciados pela adi o de enzimas exógenas, porém o peso dos animais influenciou os níveis de amilase e tripsina.

Open Journal of Stomatology (OJST) , 2013, DOI: 10.4236/ojst.2013.39A001
Abstract:

The objective of this study was to systematically review the literature about the use of the operating microscope in endodontics. It used sources of bibliographic cataloging electronically identified by MEDLINE via PubMed, LILACS, BBO and Scopus, using as descriptors: Endodontics, anatomy and microscopy. The selected articles were identified from the titles and abstracts, taking into consideration the following criteria: publications ranging from January 2001 to November 2012, case reports, published in an indexed journal, and publications in English language. The search showed 167 articles related to this topic, and these 21 articles met the inclusion criteria. These indicated that a higher magnification helps coronary access and the location of channels to identify and interpret the complexities of the anatomy of root canals, the removal of nuclei and intracoronary fractured instruments, to minimize trauma of surgeries in soft and hard tissues, and detect fractures and microfractures. It was found that its use has provided Endodontics with a significant improvement in vision of the operative field, offering better quality jobs and a higher success rate.

Abstract:

The fruit production for export is an economically significant activity in the Valley of S?o Francisco River, especially in the irrigated lands of Petrolina-PE/Juazeiro-BA, Brazil. The development of new genetic material most suitable to the tropical climate and the demands of the consumer market have led to the selection of new seedless grapes cultivars. In this case, the use of the embryo rescue technique has produced satisfactory results for obtaining such materials, especially in the semiarid region. This study aimed to evaluate the in vitro development of intraspecific hybrids of grapevine (Vitis vinifera L.), derived from the rescue of immature embryos resultant from the crossing of “Superior Seedless” and “Thompson Seedless” Brazilian clones. To establish and develop the cultivation, the culture media was supplemented with 30 g/L sucrose, 0.1 g/L myo-inositol, 0.002 g/L glycine, 0.1 mg/L indoleacetic acid (IAA), 6.5 g/L of agar, adjusted pH to 5.7. The experiment was evaluated after 90 days. The variables measured were: number of nodes, number of leaves, plant height (cm), number of roots and length (cm) of the root system and internodes. The period of 60 days of in vitro culture of ovules resulted in the highest values of embryos (about 50%), as well as better characterized developmental stages with higher germination (47.3%). The three types of hybrid grapes evaluated in micropropagation showed very similar values of the measured parameters, even having originated from embryos of different developmental stages.

Abstract: Este trabalho utilizou como fonte primária as leis contidas nas Ordena es Afonsinas concernentes aos judeus e, assim, pretendeu-se compreender como se configurava a situa o destes no reino português a partir das disposi es contidas naquelas, uma vez que abarcavam leis de regulamenta o específica ao povo mosaico. A problemática empregue nesta pesquisa teve como fulcro as políticas de afirma o régia e como estas se valiam das leis criadas e/ou ratificadas na compila o, para auxiliar no intuito da centraliza o do poder. Como o tema da pesquisa restringiu-se aos judeus em Portugal, buscou-se analisar a fonte com o olhar direcionado à problemática supracitada, sem deixar de lado as considera es relacionadas à condi o de minoria religiosa daquele povo, já que por esse motivo formavam uma comuna independente estruturalmente das comunas crist s e, portanto, também interagiam nas linhas de for a entre a dinamica social do poder local das comunas e o poder centralizador dos monarcas.
