Seleção de micro-organismos celulolíticos comparados com o Trichoderma reesei CCT 2768

As celulases atualmente são enzimas extensivamente estudadas para a hidrólise de resíduos lignocelulósicos para obtenção de açúcares fermentescíveis utilizáveis em diferentes processos biotecnológicos, como a produção de bioetanol. O objetivo deste trabalho foi encontrar fungos celulolíticos que sejam eficientes nos processos de degradação da biomassa lignocelulósica. No presente trabalho foram selecionados 4 fungos celulolíticos previamente isolados pelo Laboratório de Biotecnologia Industrial (UNESP – Assis). Estes fungos foram cultivados em bagaço de cana-de-açúcar como substrato e para seus extratos enzimáticos foram testados suas atividades para celulases (FPase) e endoglucanases (CMCase). Os fungos FS09 (0,054 FPU/mL e 1,79 FPU/g de substrato, 0,874 U/mL e 29,1 U/g de substrato) e M51 (0,049 FPU/mL e 1,62 FPU/g de substrato, 1,094 U/mL e 36,46 U/g de substrato), mostrando valores superiores ao fungo T.reesei CCT 2768 que é referência em estudos e produção de celulases.

Seleção de famílias e progênies de irmãos completos de cana-de-açúcar para atributos tecnológicos e de produção pelo método de REML/BLUP

The objective of this study was to assess families and highlight the superior progenies of sugarcane originating from 38 biparental crosses for the following attributes: tons of cane per hectare (TCH), tons of biomass per hectare (TBIOH), brix (% cane juice), fiber content, purity, pol and total recoverable sugar (TRS). The data were analyzed by mixed model REML / BLUP in the REML (Restricted Maximum Likelihood) allowed us to estimate genetic parameters and BLUP (best linear unbiased prediction) to predict the additive and genotypic values. The best family for the attributes TCH and TBIOH was 41, whose parents are cultivars IACSP022019 x CTC9. In individual selection for TCH, the plant number 3 of Block 2, the crossing 78, showed the best results. To TBIOH the plant number 33, Block 1, family 41, showed the best results. Families 40, 41, 43, 68, 69, 79, 91, 92 and 147, were higher for the variables brix, pol, purity, and ATR, where as 85 families, 147, 148, 149, 161, 163, 177, 178, 179, and 183 were higher for fiber. The family 147 whose parents are IACSP042286 x IACSP963055, showed three progenies ranked among the top ten for both brix, and for fiber, which identifies the combination as a potential source of progenies for bioenergy production.

Fatores biomecânicos relevantes na seleção dos grampos em próteses parciais removíveis com extremo livre: estudo clínico

The free-end removable partial dentures (RPD) shows a complicated and peculiar biomechanical behavior that impose high occlusion forces to the abutment teeth. By this way, the aim of this study was to evaluate the several factors that influence the clasps indication to free-end RPD. It was analysed 84 designed and planned study models of 71 patients, involving 130 clasps near-by a free-end; followed by clinical and radiographical informations. It was observed that bar clasps (“T”, “Tmod”, “i”) were used in 88.46% of abutment teeth. In the others (11.55%), it was used simple, combinated or ring circumferential clasps, and MDL. In abutment teeth with high equator line the “i” clasps were predominant (48.48%). The “Tmod” clasps were predominant in abutment teeth with low equator line (50%) or in middle third (51.35%) and “T” clasps were predominant in inclined equators with mesio-buccal (56.52%) or disto-buccal (66.66%) retention. In the posterior abutment teeth, it was prevalent the distal rest (63.52%) and embracing to the adjacent tooth. Some others factors like long clinical crown (5.38%), wrong position of abutment teeth (4.61%), aesthetics (3.07%), retention in alveolar ridge (2.3%), fragility of abutment teeth (1.53%), short clinical crown (0.76%) and short space to the clasp (0.76%) influenced directly during the clasps selection. Factors like mobility of abutment teeth, height of muscular insertions, depth of buccal fornix and antagonist arch acted like secondary factors. After the informations analysis it may be concluded that the bar clasps with distal rest and embracing to the adjacent tooth were the most indicated to free-end RPD

Avaliação dos fatores críticos para a seleção e aplicação clínica dos pinos de fibra: relato de caso cliínico

Teeth that have lost much of their coronal tooth structure need intraradical devices to achieve a desired retention of the restorative material, restoring aesthetics and function to the patient. For this purpose, various types of intracanal posts have been studied, of wich the fiber posts have been highlighted with its increasing use in the dental market. The purpose of this study was to present a clinical case of using fiberglass post. As well as critically analyze the published works and points of controversy described by different authors related to factors such as different protocols cementation, surface treatments pins, fracture toughness and compression, the possibility of microleakage, diameter and length of the pin, and the various materials used in conjunction with the intracanal retainers. Thus, we concluded that fiber posts showed as an excellent alternative for anterior teeth, since have least 2 mm of tooth remaining.

Considerações relevantes na seleção de dentes artificiais

Nowadays the search for aesthetic in removable dentures is considered a success clinical factor. Besides, both the selection of artificial denture teeth and the characterization of dentures have been based on the facial harmony and cultural factors. But these factors change over time. Therefore, the present study aimed to discuss the selection of artificial denture teeth in relation to patient’s variables such as face shape, skin color, hair color, eye color, age and gender. Moreover, artificial denture teeth’ color, shape and size were presented.

Controle do crescimento e da seleção folicular por fatores locais e sistêmicos na espécie bovina

The regulation of ovarian activity is an integrated process involving extraovarian signals and intrafollicular factors. In such process, gonadotropins have an important role, but not always crucial. The initiation of primordial follicle growth and the early stages of folliculogenesis can occur without gonadotropins, however FSH may affect the rate of preantral follicle growth. On the other hand, the antral follicle development from 1 to 4 mm in diameter is completely gonadotropin-dependent in bovine, and the alternation of dependency from FSH to LH may be part of the mechanism involved in follicular selection. Locally produced growth factors, such as the IGF system, work in association with gonadotropins throughout the follicular growth and can influence follicular selection. Thus, the integration of these extraovarian signals and intrafollicular factors seems to determine whether a follicle will continue to develop or go atretic. This review focuses on the interaction between gonadotropins and intrafollicular factors in follicular development and selection in cattle.
