Cruz, Rodrigo José Guimares;Santos, José Enemir dos;
Revista Brasileira de Zoologia , 2004, DOI: 10.1590/S0101-81752004000200016
Abstract: the testes structure of the following siluriformes was studied: pimelodus maculatus (lacepède, 1803), iheringichtys labrosus (lütken, 1874) and conorhynchos conirostris (valenciennes, 1840). the testes of these species were dissected into cranial and caudal regions. the fringes of mature testes were counted and measured. student's t-test was used to identify significant differences between fringe lengths of the two regions. to study the whole testes of each species in its resting and mature stage, testes were fixed in bouin liquid for 6-8 hours and submitted to routine histological techniques. standard histochemical techniques were used to detect carbohydrates and proteins. the testes of all species were paired and fringed organs. histologically, cranial fringes of all species were spermatogenic with cells inside cysts at the same phase of development. caudal fringes of c. conirostris were spermatogenic; while p. maculatus and i. labrosus showed caudal fringes only during secretion. histochemically, neutral glycoproteins, acid glycoconjugates, acid carboxilates, sialomucines, and acid and sulfates glycoconjugates were detected in the caudal fringe secretions of p. maculatus; and neutral glycoproteins in i. labrosus. significant differences between the fringe lengths of the cranial and caudal regions were found for all the species studied.

Guimares-Cruz, Rodrigo J.;Santos, José E. dos;Santos, Gilmar B.;
Revista Brasileira de Zoologia , 2005, DOI: 10.1590/S0101-81752005000300005
Abstract: the gonadal structure and gametogenesis of loricaria lentiginosa isbrücker, 1979 were studied through anatomical and histological techniques. forty two males and ten females in maturation/mature stage were captured in the reservoir of porto colombia, paraná river basin, minas gerais, using gill nets, from november 2001 to october 2002 (tri-monthly captures). examination of the testes revealed that they were paired, elongated and not fringed organs. histologically, the testes presented three distinct regions: cranial espermatogenic; transistion espermatogenic and secretory; and caudal exclusively secretory. standard histochemical techniques detected neutral glycoproteins from the secretion of the tubules of the caudal region. espermatogenesis occurred in cysts throughout the whole extension of the wall of the seminiferous tubules, which anastomosis themselves and liberated the spermatozoa into the lumen of the espermatic ducts. the ovaries were paired, saculiformes and, histologically, they presented ovigerous lamellae that contained the cells of ovogenic ancestry. the oocytes were classified into four stages, based on their cytological characteristics and the cell layers that surrounded them. post-ovulatory follicles and vitelogenic oocytes in the follicular atresia process also were observed.

Abstract: Vinasse is the main residue generated during alcohol, sugar and blue rum production by fermentation process. This residue is effluent that could cause serious environmental pollution due to high organic load when is not treated adequately. The aim of this work consists of evaluating the efficiency and application of heterogeneous photocatalysis with TiO2, followed by a biological treatment (activated sludge system) to reduce organic load in the referred effluent. Complete factorial designs indicated the best experimental conditions subsequent to photacatalytic and biological treatments providing a reduction of non-purgeable organic carbon (NPOC) as a variable response. After the photocatalytic process, the sample from the best experiment condition was treated by a biological process in order to verify the degradation efficiency of the effluent organic matter studied according to the hybrid system (Advanced Oxidation Process—Acti- vated Sludge System). This system, which presented more efficiency, had a photochemical treatment of 180 minutes carried out in aerated solutions, pH 9 and effluent in natura, while the biological treatment was performed at pH 8 and sludge concentration of 5 gL–1. The reduction of biochemical oxygen demand (BOD) was >80%.

Jornal Brasileiro de Psiquiatria , 2013,
Abstract: OBJETIVO: Testar a Escala de Bem-Estar Espiritual (EBE), a vers o em português da Spiritual Well-Being Scale (SWB), em uma amostra de universitários matriculados em cursos de pós-gradua o da área da saúde, avaliando suas qualidades psicométricas. Entre os diferentes instrumentos que objetivam mensurar a espiritualidade, encontra-se a SWB, adaptada recentemente para a língua portuguesa. Os 20 itens desse instrumento originalmente dividem-se em duas dimens es: bem-estar religioso (BER) e bem-estar existencial (BEE). MéTODOS: A consistência interna dessas dimens es foi avaliada pelo coeficiente alfa de Cronbach. Foi utilizada análise fatorial com rota o oblíqua para avaliar a estrutura fatorial latente. Quatrocentos e quarenta e um indivíduos responderam ao instrumento. RESULTADOS: O instrumento apresenta satisfatória consistência interna, mas a análise fatorial sugere que os itens da dimens o BEE distribuem-se em dois fatores distintos, o que chama a aten o para a complexidade da estrutura fatorial do instrumento. CONCLUS O: A estrutura fatorial da escala EBE n o é clara, e a presen a de um efeito teto em grupos religiosos específicos pode prejudicar os estudos que buscam associa es entre espiritualidade e aspectos relacionados à saúde. O uso do instrumento exige cautela, e posteriores estudos de revis o da escala s o necessários. OBJECTIVE: This study aims to test the factor structure of the Portuguese-language version of the Spiritual Well-being Scale (SWB) in a sample of postgraduate students of courses in the health area, assessing its psychometric qualities. Among the different instruments used to measure the spirituality, the SWB was recently adapted into Portuguese language. The 20 items of this instrument are originally divided into two dimensions: Religious Well-Being (RWB) and Existential Well-Being (EWB) subscales. METHODS: The internal consistency of the subscales was assessed by the Cronbach's alpha coefficient. A factor analysis with oblique rotation was used to assess the latent factor structure. Four hundred and forty-one individuals answered the SWB scale. RESULTS: The instrument has satisfactory internal consistency, but the factor analysis suggests that the items of the EWB subscale are distributed in two distinct factors, which draws attention to the complexity of the factor structure of the instrument. CONCLUSION: The factorial structure of the instrument is unclear, and the presence of a ceiling effect for religious groups may hinder the studies about the associations between spirituality and health-related characteristics.

Brazilian Journal of Infectious Diseases , 2010, DOI: 10.1590/S1413-86702010000200003
Abstract: vaccinia virus is responsible for a zoonosis that usually affects cattle and human beings in brazil. the initial clinical signs of the infection are focal red skin areas, fever, and general symptoms similar to those of a cold. then, pustules and ulcerated lesions surrounded by edema and erythema follow, as well as local lymphadenopathy that can last for weeks. cure and healing of the lesions occur over several weeks, leaving a typical scar in the skin of people and animals affected. the infection definitive diagnosis is made through morphological characterization of the virus by use of electron microscopy, followed by pcr for specific viral genes. since 1963, circulating orthopoxviruses in infectious outbreaks in several regions of brazil have been reported. later, the etiological agent of those infections was characterized as samples of vaccinia virus. in addition, the widespread use of those viruses in research laboratories and mass vaccination of militaries have contributed to increase the cases of those infections worldwide. thus, several epidemiological and clinical studies are required, as well as studies of viral immunology, public health, and economic impact, because little is known about those vaccinia virus outbreaks in brazil.
