Requalificação de um Bem Histórico: O Cemitério Japonês de Álvares Machado - SP

O Cemitério Japonês de Álvares Machado - SP, marco histórico, cultural e simbólico, tombado pelo CONDEPHAAT, foi uma obra que surgiu diante da necessidade dos imigrantes japoneses que desbravaram a área e a colonizaram, ao qual dedicaram suas vidas, contribuindo enormemente para o povoamento e desenvolvimento do local. A chegada dos primeiro colonos japoneses coincide com o início do povoamento da porção sudoeste paulista, fato que foi impulsionado pela chegada da Estrada de Ferro Sorocabana à região. Passados mais de 90 anos, o sítio histórico apresenta boa conservação, no entanto há diversas ameaças à integridade física que urgem serem estudadas e sanadas. O presente trabalho visa levantar essas questões e propor soluções, tendo em vista a legislação, as recomendações de órgãos nacionais e internacionais de preservação de bens culturais, tais como UNESCO, ICOMOS, IPHAN, CONDEPHAAT e também através de pesquisa bibliográfica. Há também a proposta de intervenção arquitetônica, com o intuito de oferecer infraestrutura para recepção de visitantes, principalmente durante o evento anual do Shokonsai e a visita dos familiares que ali estão enterrados; oferecer novos usos para o local, de modo a ser ocupado e utilizado permanentemente, favorecendo a manutenção e ampliando a mensagem cultural, simbólica e da memória coletiva do local

Ganho ponderal pós-gastrostomia em crianças com Paralisia Cerebral e Tetraplegia espástica

O objetivo deste estudo foi avaliar a evolução ponderal pós-gastrostomia em crianças com paralisia cerebral tipo tetra-plegia espástica. Mediante análise de variância para dados pareados, 33 crianças foram avaliadas nos momentos: 6 meses antes, à gastrostomia, 6 meses e 18-24 meses após. A mediana da idade à gastrostomia foi de 48,1 meses. 75,8% eram do gênero masculino. Houve ganho ponderal na comparação dos momentos: 6 meses antes, à gastrostomia e 6 meses após em relação a 18-24 meses após (p<0,001). Utilizando-se referencial específico de crescimento para paralisia cerebral, à gastrostomia e 18-24 meses após as crianças apresentavam percentil ≤10 (respectivamente, 52,4% e 33,3%) e >10 (respectivamente, 47,6% e 66,6%). As medianas do escore z do peso foram: 6 meses antes (-5,1), à gastrostomia (-5,0), 6 meses após (-4,7) e 18-24 meses após (-4,4), não havendo diferença significativa. Escore z ≤-2 foi observado em 75% das crianças 6 meses antes, 81,8% à gastrostomia, 75% 6 meses após e 64,5% 18-24 meses após. Na análise da mediana da idade, para as crianças com idade ≤ 48,1 meses não houve diferenças no escore z nos diferentes momentos. Para aquelas com idade >48,1 meses houve diferença significativa entre 6 meses antes e 18-24 meses após. Considerando as crianças mais (z≤-5,0) e menos (z>-5,0) comprometidas nutricionalmente, houve diferença significativa entre as mais comprometidas (p = 0,04) na comparação entre gastrostomia com 6 meses após e com 18-24 meses após. Este estudo demonstrou que 18-24 meses após a gastrostomia houve aumento ponderal para todas as crianças e aumento do escore z do peso naquelas com mais idade e mais comprometidas nutricionalmente.

Severe distal cytomegalovirus esophagitis with aerodigestive symptoms in an immunocompetent infant

We report a case of an immunocompetent infant, with no evidence of neurological disorders, which developed clinical manifestation of recurrent crisis of choking, dysphagia, laryngeal stridor and sub costal retractions since the first day of life. Direct laryngoscopy was unremarkable. Upper gastrointestinal series showed a dilated tortuous esophagus with severe peristalsis impairment and reflux episodes till the proximal third of the esophagus. An upper gastrointestinal endoscopy showed a moderately dilated esophagus with erosive lesions in the distal esophagus. Esophageal biopsy specimens revealed CMV inclusion bodies associated to moderate inflammation and immunohistochemistry was positive for CMV early antigen. Prolonged 24 h esophageal pH metry was within normal limits. Antiviral therapy with intravenous ganciclovir was introduced and was associated with rapid improvement of the symptoms. Child gradually increased oral intake and weight gain, and there were no side effects related to therapy. Thus, the respiratory symptoms could have been a supra esophageal manifestation of a non-acid reflux disease related to the CMV esophagitis.

PB1908-27 Loss From Cornstalk Disease in Custer County, Nebraska, During the Winter of 1906-1907 (Distributed January 1908, Reprinted December 1930)

"Cornstalk disease" is the name given to the cause or causes of death of cattle allowed to run in fields of standing cornstalks from which the ears have been gathered. It is probable that "many different maladies have been included under this name." In Nebraska, however, there is such a similarity in the symptoms reported by the farmers that it seems probable that the great majority of the losses attributed to cornstalk disease are really due to some common cause. As to the exact nature of this cause nothing is known. However, various theories have been advanced, and methods of prevention or treatment based upon these theories have been described.

Spermatogenesis in goats with and without scrotum bipartition

The objective of the present research was to quantify the seminiferous epithelium cells, spermatogenesis efficiency and characterize the ultrastrucure of Sertoli cells in goats. Eighteen goats were used and divided into three groups: Group I - goats without bipartition of the scrotum; Group II - animals with bipartition of the scrotum in up to 50% of the testicular length; Group III - goats with bipartition of the scrotum in more than 50% of the testicular length. The goat testes in Group III had a greater number of primary spermatocytes (25.37 +/- 4.55 cells per cross sections), spermatids (112 +/- 15.12 cells per cross sections), and Sertoli cells (9.46 +/- 1.74 cells per cross sections) than the animals in Groups land (P <0.05). The spermatogenic mitotic, meiotic, and general efficiency were greater in animals in Group III (1.25 +/- 0.28; 5.12 +/- 1.63; 6.44 +/- 1.96) when compared to those in Groups I and II. Sheet-like processes originated from the Sertoli cell body as simple and smooth structures which involved almost all the surface of germ cells. Slender cord-like processes originated from Sertoli cells and also from the sheet-like processes. The relative frequency of the cycle stages showed differences among the groups of goats studied, and the highest frequency was in Stage 3 (20.68% for goats in Group I, 21.15% for those in Group II, and 16.89% for the animals in Group III). In conclusion, goats with bipartition of the scrotum have a greater number of germ and Sertoli cells per cross section of seminiferous tubule, that indicated a greater sperm production when compared to the other groups, and the ultrastructure of the Sertoli cell process did not present any relationship with bipartition of the scrotum.

Experimental hyperprolinemia induces mild oxidative stress, metabolic changes, and tissue adaptation in rat liver

The present study investigated the effects of chronic hyperprolinemia on oxidative and metabolic status in liver and serum of rats. Wistar rats received daily subcutaneous injections of proline from their 6th to 28th day of life. Twelve hours after the last injection the rats were sacrificed and liver and serum were collected. Results showed that hyperprolinemia induced a significant reduction in total antioxidant potential and thiobarbituric acid-reactive substances. The activities of the antioxidant enzymes catalase and superoxide dismutase were significantly increased after chronic proline administration, while glutathione (GSH) peroxidase activity, dichlorofluorescin oxidation, GSH, sulfhydryl, and carbonyl content remained unaltered. Histological analyses of the liver revealed that proline treatment induced changes of the hepatic microarchitecture and increased the number of inflammatory cells and the glycogen content. Biochemical determination also demonstrated an increase in glycogen concentration, as well as a higher synthesis of glycogen in liver of hyperprolinemic rats. Regarding to hepatic metabolism, it was observed an increase on glucose oxidation and a decrease on lipid synthesis from glucose. However, hepatic lipid content and serum glucose levels were not changed. Proline administration did not alter the aminotransferases activities and serum markers of hepatic injury. Our findings suggest that hyperprolinemia alters the liver homeostasis possibly by induction of a mild degree of oxidative stress and metabolic changes. The hepatic alterations caused by proline probably do not implicate in substantial hepatic tissue damage, but rather demonstrate a process of adaptation of this tissue to oxidative stress. However, the biological significance of these findings requires additional investigation. J. Cell. Biochem. 113: 174183, 2012. (C) 2011 Wiley Periodicals, Inc.

Taxonomic and distributional notes on Telebasis Selys, 1865, with a redescription of T. pallida Machado, 2010, and an evaluation of the T. racenisi Bick & Bick, 1995 "complex" of species (Odonata, Coenagrionidae)

A full checklist of the species of Telebasis Selys, 1865, housed in the Brazilian collections Colecao Entomologica Prof. Jose Alfredo Pinheiro Dutra, Departamento de Zoologia, Instituto de Biologia, Universidade Federal do Rio do Janeiro (DZRJ), and Museu de Zoologia, Universidade de Sao Paulo (MZSP) is presented. A total of 325 specimens representing 19 species were studied. Ten new records for Brazilian States were found for T. carmesina Calvert, 1909 (Rio de Janeiro and Rio Grande do Sul), T. corallina (Selys, 1876) (Pernambuco), T. demarara (Williamson, 1917) (Maranhao), T. filiola (Perty, 1834) (Paraiba and Santa Catarina), T. gigantea Daigle, 2002 (Sao Paulo), T. inalata (Calvert, 1961) (Mato Grosso do Sul), T. pallida Machado, 2010 (Goias) and T. obsoleta (Selys, 1876) (Mato Grosso do Sul), as well as a new record of T. carminita Calvert, 1909 for Suriname. Telebasis pallida Machado, 2010 is redescribed and diagnosed based on 14 males collected near the type locality, and its genital ligula is described and illustrated for the first time. Furthermore, the status of the three species of the Telebasis racenisi Bick & Bick, 1995 complex is evaluated. Of these, Telebasis pareci Machado, 2010 syn. n. is proposed as junior subjective synonym of Telebasis lenkoi Machado, 2010, and a possible synonymy among the three species is discussed under T. racenisi.
