Abundance and temporal-spatial distribution of the rock shrimp Sicyonia dorsalis Kingsley, 1878 (Decapoda, Penaeoidea) from the northern coast of São Paulo state, Brazil.

Abundance and ecological distribution of the rock shrimp Sicyonia dorsalis from the northern coast of São Paulo State (Brazil) was investigated during a two-year period (July 2001 to June 2003). Monthly collections were conducted in the Ubatuba (UBA) and Caraguatatuba (CA) regions, using a commercial shrimp boat equipped with double-rig nets. In each region, seven depths were delimited (5 m to 35 m). A total of 1,752 and 1,894 shrimp were obtained at UBA and CA, respectively. The distribution of S. dorsalis differed among depths, years, and seasons. Highest abundance values were recorded in depths where silt and clay comprised more than 70% of the sediment. The majority (89%) of captured specimens were caught in the first year, in periods of lower mean temperature, mainly in the spring of 2001, when the intrusion of cold South Atlantic Central Waters (SACW) was more intense. In such period, the differences in the abundance of shrimps in each region (UBA = 1,118 and CA = 493) suggested that S. dorsalis migrated to the north (UBA), during the SACW intrusion. Thus, sediment type and water temperature are among the most important variables affecting the bathymetric distribution of S. dorsalis in these regions.

Histological study of hamster buccal mucosa following topical application of DMBA and exposition to low power 337 nm laser light

The aim of the present work is to analyze the histological changes on hamster buccal mucosa caused by the topical use of 7,12-dimethylbenzanthracene (DMBA) and exposition to a 220 μJ/pulse nitrogen laser light (@ 337 nm) at an average power of 2,3 mW. Twenty-one hamsters divided into two experimental groups were treated six times with DMBA. One hamster was kept as control. Group I was composed by ten hamsters and was submitted only to DMBA. Group II, also with ten hamsters, received the same treatment as group I and was exposed to the laser radiation. The time duration of each irradiation section was 10 seconds. All the treatment happened in alternated days. The histological analysis took place twice, after the end of the treatment and after sixty days. Both experimental groups presented dilatation of vessels, thickening of the epithelial tissue and the presence of inflammatory infiltrates. The preliminary results indicates that in group II the number of dilated vessels and its new area are much more significant than in group I.

Evaluation of skin hydration after exposition to the aqueous and hydroalcoholic bases and silicone emulsion

Several dermocosmetic bases even without active substances, can increase the cutaneous hydration, resulting in a beneficial effect to the skin. The evidence and interpretation of possible hydration effect of formulations in the skin can be carried through by means of histopathological and histomorphometrical evaluation, a time that allows the analysis of the epithelial tissue, of dermis and also of the cellular characteristics. The objective of this research was to evaluate the skin hydration after exposition to the aqueous and hydroalcoholic bases and silicone emulsion. Swines had areas submitted to treatments during 15 days with three different formulations (F1 - aqueous gel, F2 - hydroalcoholic gel and F3 - silicone emulsion). By means of histometric and histopathological techniques were gotten the thickness of the epidermis and stratum corneum. Comparison of means was done using ANOVA followed by the Tukey test. The F1 provoked significant increase in the thickness of the epidermis. The formulaton F2 provoked significant reduction in the thickness of the epidermis and stratum corneum. F3 not presented significant difference in this structures. According to the study, the type of base chosen intervenes with the skin hydration.

Reproductive biology of Plagioscion magdalenae (Teleostei: Sciaenidae) (Steindachner, 1878) in the bay of Marajo, Amazon Estuary, Brazil

Plagioscion magdalenae (pescada-curuca) é um sciaenídeo bentopelágico, de importância comercial, amplamente distribuído na bacia do rio Amazonas. O objetivo deste trabalho foi descrever a biologia reprodutiva dessa espécie na baía do Marajó, estuário Amazônico, Brasil. Neste estudo foi determinado o estádio do desenvolvimento gonadal, tamanho de primeira maturação gonadal (L₅₀), proporção entre sexos, época e o tipo de desova. A coleta foi realizada bimestralmente no período de dezembro de 2005 a outubro de 2006. Foi examinado um total de 251 exemplares, variando entre 220 e 590 mm de comprimento total (CT). A relação peso-comprimento para fêmeas, machos e sexos agrupados foi altamente significativa, com alometria positiva. O L₅₀ foi de 279 mm considerando sexos agrupados, 305 e 269 mm CT para fêmeas e machos respectivamente. A proporção entre sexos para o total de indivíduos foi favorável aos machos (2,02 machos: 1 fêmea). Macroscopicamente, as gônadas foram classificadas em imatura, em maturação, matura e desovada. Considerando-se as avaliações macro e microscópicas das gônadas, foi registrado um período prolongado de desova, principalmente entre agosto e fevereiro.

O Futuro (1862-1863), Jornal das Famílias (1863-1878) e A Estação (1879-1904); três periódicos em que colaborou Machado de Assis

Machado de Assis (1839-1908) teve sua carreira marcada pela constante atividade de colaboração em periódicos, dentre os quais nos interessam particularmente O Futuro (18621863), o Jornal das Famílias (1863-1878) e A Estação (1879-1904). Por sua atuação constante e eficaz nesses veículos, o escritor foi considerado seu principal colaborador. As três revistas, por sua vez, marcaram sua presença no processo de formação de Machado: O Futuro presenciou o início da trajetória do escritor, e o Jornal das Famílias e A Estação, por seu longo período de circulação, ofereceram-lhe maior espaço para a prática e o aperfeiçoamento no gênero narrativo, principalmente na produção contos, essencial para a consagração de Machado de Assis no panorama da literatura brasileira. Assim sendo, é importante conhecer as principais características dessas revistas, uma vez que o perfil das publicações também devia ser levado em conta pelos escritores na produção de seus textos.

Effects of the acute exposition to glyphosate-based herbicide on oxidative stress parameters and antioxidant responses in a hybrid Amazon fish surubim (Pseudoplatystoma sp)

The aim of this study was to investigate the effects of acute glyphosate (active ingredient) exposure on the oxidative stress biomarkers and antioxidant defenses of a hybrid surubim (Pseudoplatystoma sp). The fish were exposed to different herbicide concentrations for 96 h. The thiobarbituric acid-reactive substances (TBARS), protein carbonyls and antioxidant responses were verified. The 15 mg a.p L-1 of herbicide resulted in the death of 50% of the fish after 96 h. An increase in liver and muscle TBARS levels was observed when fish were exposed to the herbicide. The protein carbonyl content was also increased in the liver (4.5 mg a.p L-1 concentration) and brain (2.25 mg a.p L-1 concentration). The antioxidant activities decreased in the liver and brain after exposure to herbicide. Levels of ascorbic acid in the liver (2.25 mg a.p L-1 and 4.5 mg a.p L-1 concentrations) and brain (2.25 mg a.p L-1 concentration) were increased post-treatment. Levels of total thiols were increased in the liver and brain (2.25 mg L-1 and 7.5 mg a.p L-1, respectively). Glyphosate exposure, at the tested concentrations affects surubim health by promoting changes that can affect their survival in natural environment. Some parameters as TBARS and protein carbonyl could be early biomarkers for Roundup exposure in this fish species. (C) 2014 Elsevier Inc. All rights reserved.

Revista Popular (1859-1863) e Jornal das Famílias (1863-1878): um perfil dos periódicos de Garnier

The purpose of this paper is to show some characteristics and essential information related to the Brazilian periodicals in the 19th century Revista Popular (1859-1862) and Jornal das Famílias (1863-1878), whose owner was the Frenchman Baptiste Louis Garnier. By that time the proliferation of periodicals attracts attention mainly because several of them had ephemeral existence, in opposition to Garnier’s periodicals which as a whole amount to 19 years in circulation. The research on these periodicals becomes relevant since they are well succeeded publications whose study makes possible the widening of the knowledge on social and cultural aspects of a very important period in Brazilian society.

Gestational and lactational exposition to Di-N-butyl-phthalate (DBP) increases inflammation and preneoplastic lesions in prostate of wistar rats after carcinogenic N-methyl-N-nitrosourea (MNU) plus testosterone protocol

In the present study, it was evaluated the susceptibility of prostatic lesions in male adult rats exposed to Di-N-butyl-phthalate during fetal and lactational periods and submitted to MNU plus testosterone carcinogenesis protocol. Pregnant females were distributed into four experimental groups: CN (negative control); CMNU (MNU control); TDBP100 (100 mg/kg of DBP); TDBP500 (500 mg/kg of DBP). Females from the TDBP groups received DBP, by gavage, from gestation day 15 (GD15) to postnatal day 21 (DPN21), while C animals received the vehicle (corn oil). CMNU, TDBP100, and TDBP500 groups received a single intraperitoneal injection of MNU (50 mg/kg) on the sixth postnatal week. After that, testosterone cypionate was administered subcutaneously two times a week (2 mg/kg) for 24 weeks. The animals were euthanized on PND220. Distal segment fragments of the ventral (VP) and dorsolateral prostate (DLP) were fixed and processed for histopathological analysis. Protein extracts from ventral prostate were obtained, and western blotting was performed to AR, ERα, MAPK (ERK1/2), and pan-AKT. Stereological analysis showed an increase in the epithelial compartment in TDBP100 and TDBP500 compared to CN. In general, there was increase in the incidence of inflammation and metaplasia/dysplasia in the DBP-treated groups, mainly in DLP, compared to CN and CMNU. Proliferation index was significant higher in TDBP500 and PIN (prostatic intraepithelial neoplasia) was more frequent in this group compared to CMNU. Western blot assays showed an increase in the expressions of AR and MAPK (ERK1/2) in the TDBP100 compared to CN, and ERα and AKT expressions were higher in the TDBP500 group compared do CN. These results showed that different doses of DBP during prostate organogenesis in Wistar rats could increase the incidence of premalignant lesions in initiated rats inducing distinct biological responses in the adulthood. © 2015 Wiley Periodicals, Inc.

Music at the Fair! The Trans- Mississippi and International Exposition. An Interactive Website

“Music at the Fair!” gives the daily musical programs for The Trans-Mississippi and International Exposition, held in Omaha, Nebraska, June 1 through October 31, 1898. The Trans-Mississippi and International Exposition brought an unprecedented array of local, national, and international musical acts to Omaha, NE in 1898. This served to designate Omaha, "the gateway to the west" as a musical hub, as well as to incite musical excitement in the region. Some of the more popular acts featured were the Theodore Thomas Orchestra, the U.S. Marine Band, and the Apollo Club of Chicago. Many more groups and their musical programs can be found within the pages of this site. The “Music at the Fair!” website was created by Grace Carey, and last revised on May 19, 2006.It is the result of a two- year research grant funded by an Undergraduate Creative Activities and Research Experiences (UCARE) grant through the University of Nebraska at Lincoln. It is an extension of an ongoing project on music at the TME by Music Professor Peter Lefferts. The primary sources of information for the site are the following newspapers from June – November 1898: The Omaha Daily Bee, the Omaha Evening Bee, and the Omaha World Herald, and the the official programs of the fair located in the archives at the Omaha Public Library. I would like to thank the helpful staff at the Nebraska State Historical Society and the downtown branch of the Omaha Public Library.
