Criopreservação de sêmen equino: uma revisão

A utilização do sêmen resfriado na espécie equina é amplamente difundida, no entanto, quando se trata do sêmen congelado existem certos entraves, os quais tornam o emprego desta biotécnica limitado. Porém seu uso está crescendo e com isso pesquisas com meios diluidores e protocolos de congelação têm sido realizados, a fim de se estabelecer um protocolo que seja eficiente para a congelação do sêmen da maioria dos garanhões. Essa revisão sistemática tem como objetivo a análise de estudos que tratam da congelabilidade do sêmen equino, bem como os principais componentes de um meio diluidor, a fim de demonstrar suas funções e fornecer alternativas para a substituição ou associação, principalmente de crioprotetores. Para tanto, foram utilizadas bases de dados com a seguinte estratégia: criopreservação, congelamento, diluentes, crioprotetores, glicerol, leite, sêmen e equino, presentes no título ou resumo. Dentre os artigos encontrados foram selecionados 15 artigos nas línguas portuguesa, espanhola e inglesa, publicados em revistas científicas ou teses de mestrado, doutorado e trabalhos de conclusão de curso. Tais artigos permitiram concluir que não existem protocolos de congelamento definidos para grupos de animais, mas que deve ser observado cada indivíduo, ressaltando sua peculiaridade e estabelecendo o melhor diluente e protocolo

Tempo, finitude, velhice e fotografia

This article analyzes and discusses the experience of time in old age through the relations of the elderly with photography. We did photography workshops with a group of elders exploring with them the sense of the photographic act death, as an act of freezing and stopping time and also the sense of exploring the future to create, through the photographic act, an image that can symbolize moving on in life.

Annual, seasonal and spatial abundance of the seabob shrimp Xiphopenaeus kroyeri (Decapoda, Penaeidae) off the Southeastern coast of Brazil

We investigated the influence of environmental factors in spatial and temporal distribution of the seabob shrimp Xiphopenaeus kroyeri in Santos Bay and São Vicente Estuary, state of São Paulo, Brazil. Monthly samples were obtained, from May 2008 through April 2010, from four locations in the estuary and four in the bay. No individual was collected in the estuary and this was attributed to the low salinity means recorded in this environment. We collected 109,153 individuals in the bay and there was no difference in abundance between the two years comprised by the study period. The similarity in spatial distribution can be related to sediment grain size that in all sampling locations showed great amount of very fine sand. The largest amount of reproductive females was obtained in early 2010, when temperature was high, and this could have increased the juvenile recruitment in April 2010. According to our results, the distribution of X. kroyeri in the study area is influenced by temperature, which is related to reproduction, and salinity, limiting the entrance of individuals in the estuarine region.

Ocurrence of male morphotypes of Macrobrachium amazonicum (Caridea, Palaemonidae) in a population with an entirely freshwater life cycle

This study records, for the first time, the occurrence of all four male morphotypes in a population of Macrobrachium amazonicum from a continental environment, with an entirely freshwater life cycle. The specimens studied came from the Tietê River, state of São Paulo, Brazil, and were collected in a lotic environment downstream from Ibitinga Dam. This population was compared with other continental populations, including a population from the dam itself, collected in a previous study. Four samples of 30 minutes were taken monthly, using a trap, from January to April 2011. Each male specimen was measured with respect to seven body dimensions as follows: carapace length (CL), right cheliped length (RCL), dactyl length (DCL), propodus length (PPL), carpus length (CRL), merus length (ML) and ischium length (IL). The relative growth was analyzed based on the change in growth patterns of certain body parts in relation to the independent variable CL. The four male morphotypes proposed for the species were found using morphological and morphometric analyses. Different biological characteristics were found between the populations studied. The male population of the lake of Ibitinga and from Pantanal presented mean sizes and number of morphotypes lower than the population studied here. These differences seem to be closely related to ecological characteristics of the environments inhabited by these populations. Our results supported the hypothesis that coastal and continental populations of M. amazonicum belong to the same species.

Behavior of Staphylococcus aureus and autochthone microbiota in fresh sausages added of sodium nitrite and stored under refrigeration

Fresh sausages are cured meat products that may be contaminated with Staphylococcus aureus during the manufacturing procedure, which is frequently related with inadequate handling practices. The use of nitrite in meat products has proven efficacy against Clostridium botulinum, and studies indicate that bactericidal action against S. aureus depends on factors that are intrinsic and extrinsic to the product. The objective of the present study was to evaluate the effect of nitrite concentration, and pH on S. aureus and psychrotrophic autochthone microbiota in fresh sausages stored at different times and temperatures. Fresh sausage were produced at nitrite concentrations 50, 150 and 200ppm and contaminated with S. aureus. The sausages were storage at refrigeration (7 and 12 degrees C) and the quantification of S. aureus and psychrotrophic microorganisms was carried out on days 0, 2, 4, 7, and 10. Results showed that nitrite concentrations and the temperatures used had minimal effect on the multiplication of S. amens and psychrotrophic autochthone microbiota. Final counts depended only on the length of storage: at the end of 10 days, counts were statistically similar in the different groups, showing that temperature and nitrite concentrations used did not control microbial growth effectively. It is suggested that the product should be stored below 7 degrees C or at freezing temperatures for greater microbiological stability.
