Fecundidade e fertilidade do camarão-da-Amazônia, Macrobrachium amazonicum (Heller, 1862) (Decapoda: Palaemonidae) em dois ambientes estuarinos do estado do Pará

O Macrobrachium amazonicum é o camarão de água doce com ampla exploração pesqueira na região amazônica, em virtude da abundância e boa aceitação no mercado consumidor. O objetivo deste estudo foi caracterizar a fecundidade e fertilidade de M. amazonicum em dois ambientes estuarinos no Estado do Pará. De forma que foram realizadas coletas mensais no período de setembro de 2008 a agosto de 2009, nos município de Vigia e Belém na Ilha de Mosqueiro, as fêmeas foram até o Laboratório de Ecologia Aquática e Aqüicultura Tropical - LECAT no campus da Universidade Federal Rural da Amazônia – UFRA, em Belém. Para a determinação da fecundidade foram colecionadas mensalmente em média 30 fêmeas ovígeras de cada ponto de coleta, os ovos aderidos aos pleópodes foram retirados, utilizando hipoclorito de sódio como 2% de cloro ativo e estocado em álcool 70%. A fecundidade individual foi determinada a partir da contagem total dos ovos. Para a determinação do volume dos ovos foram selecionados de cada local de coleta, aleatoriamente, 50% do número total de fêmeas ovígeras destinadas a fecundidade, seguindo dois grupos: ovos pigmentados e não-pigmentados. Para determinar a fertilidade, as fêmeas ovígeras de M. amazonicum foram estocadas individualmente em aquários de vidro de 2L. Após a eclosão, as larvas foram sifonadas e contadas. Para todas as fêmeas foi aferido o peso de cada exemplar e avaliada sua biometria com o auxílio de um paquímetro de precisão. As fêmeas de M. amazonicum oriundas do Município de Vigia tiveram comprimento absoluto entre 4,8 e 9,3 cm e peso entre 2,21 e 11,81g, com fecundidade absoluta entre 38 e 5.749 ovos (2.296 ± 1.288 ovos). Para as fêmeas de Belém, provenientes da ilha de Mosqueiro, o comprimento variou entre 3,71 e 8,14 cm, o peso entre 1,27 e 11,2g, com fecundidade absoluta variando de 123 e 7.571, com média de 1.448 ± 990 ovos. O volume de ovos para as fêmeas obtidas no Município de Vigia, referente aos ovos não-pigmentados, apresentou volume médio de 141,37mm³, enquanto que para ovos pigmentados o volume foi de 116,13mm³. As fêmeas provenientes da Ilha de Mosqueiro, com ovos não-pigmentados apresentaram volume médio de 118,97mm³ e ovos pigmentados o volume médio calculado foi de 144,61mm³. A análise da fertilidade para as fêmeas do município de Vigia apresentou comprimento entre 5,41 e 9,72 cm e peso entre 2,51 e 9,60g, a fertilidade absoluta foi 14 e 4.430 larvas, com média de 1.152 ± 822 larvas por fêmea. As da ilha de Mosqueiro apresentaram comprimento entre 3,53 e 7,67 cm e peso entre 1,12 e 8,77 g com fertilidade absoluta entre 7 e 4.121 e média de 755 ± 871 larvas por fêmea. Os valores referentes a fertilidade e fecundidade para os município de Vigia e Belém - Ilha de Mosqueiro indicam que há proporcionalidade entre as variáveis de comprimento e peso. Apesar de apresentar fecundidade e fertilidade menor que os valores reprodutivos apresentados para outras espécies de interesse comercial, os valores aqui mostrados evidenciam que nestes dois locais a espécie podem fornecer matrizes potenciais para aquicultura.

The Palm Collection of UNESP/FCAV - Jaboticabal, Sao Paulo State, Brazil

The palm collection of UNESP/FCAV, Jaboticabal, Sao Paulo State, Brazil, was created in 1966 with the aim to keep different palm species for research purposes and conservation of native species, especially those threatened. Native and exotic species comprise the collection, which is held at the institution, where several studies with different species and in different areas are undertaken. Nevertheless, palm seeds and seedlings are also distributed to other research centers. The botanical review of the collection began in 2003 and there are, currently, 143 species or hybrids, in a total of 331 specimens. Considering the most ancient species, the immediate identification of many of them was possible; however, for others, such as the Attalea, Orbignya, Syagrus and Scheelea genera, future morphological studies is required, like the karyotype one or using molecular markers. Many species have been introduced and many seeds have been currently investigated regarding their germination process for future inclusion in the collection. Some of the palms do not bloom; others, however, bloom, but do not bear fruits; and others bear fruits, but their seeds do not germinate. They are either young plants, fruits which are constantly attacked by insects, like the Syagrus species and hybrids, or dioecious plants.

Data collection on bone density of mandibular alveolar bone on a Hounsfield scale of the dental apex of the cranial root of the first inferior molar in dogs using computed tomography at FMVZ-UNESP

The head is the most important and specialized region in the body because it contains a range of specialized organs and, because it has interconnections between specialized organs, there is a great overlap of images. Thus, computed tomography (CT) helps in diagnosing diseases in this region, such as oral conditions, as they provide millimetric slices or cuts and demonstrate the relationship between the various anatomical structures involved, in volume and depth. Within dentistry, CT helps in the identification of pathological processes such as infection, tumors, visualization of embedded teeth and bone bed. This study aimed to assess the density of the mandibular alveolar bone at a determined point to later predict how periodontal disease is involved in bone resorption. For this, we performed a blind retrospective study (n = 124) of the CT scan files of dog skulls at FMVZ-UNESP in order to determine the density of the jaw bone using a Hounsfield scale, in the region of the dental apex of the cranial root of the first molar tooth in dogs. The results obtained were evaluated using mean and standard deviation (27.28 +/- 9.53 HU) in order to predict the normal density of the mandibular alveolar bone in the studied region. Thus, this data analysis allows a more concise evaluation of bone resorption of mandibular alveolar bone and, therefore, provides an adequate surgical planning in cases of osteosynthesis given mainly by the presence of installed periodontal disease.

Effect of human whole saliva on the in vitro adhesion of Candida albicans to a denture base acrylic resin: a focus on collection and preparation of saliva samples

Objective In studies on Candida albicans adhesion to surfaces, diverse protocols have been used for collection and preparation of saliva samples. Thus, this study investigated whether variations in the centrifugation parameters and number of donors of saliva would influence the adhesion of C. albicans to a denture base resin. Methods Resin acrylic samples (n = 72) were made and then divided into four groups: (a) control – specimens were left without preconditioning in saliva; (b) three experimental groups, in which the specimens were preconditioned with saliva collected from 15 volunteers and centrifuged at 12 000 g for 5 min (G1); from 15 volunteers and centrifuged at 18 000 g for 30 min (G2); and from one volunteer and centrifuged at 12 000 g for 5 min (G3). Candida adhesion was evaluated by both the 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino) carbonyl]-2H-tetrazolium hydroxide (XTT) reduction method and crystal violet staining. Data were analyzed by one-way analyses of variance (P = 0.05). Results For XTT reduction assay, groups G2, G3, and control were not significantly different, whereas group G1 showed significantly higher absorbance value than control. For crystal violet staining there were no significant differences among all groups. Conclusion Variations in the centrifugation parameters and number of donors of saliva may influence C. albicans adhesion to denture base resins.
