Melanocytes in the testes of Eupemphix nattereri (Anura, Leiuperidae): Histological, stereological, and ultrastructural aspects

Ectothermic vertebrates have a well-developed system of melanin-containing cells, which localize in several organs and tissues and compose an extracutaneous pigmentary system. This research aimed at characterizing histological and ultrastructural patterns of pigmented cells in the testes of the anura Eupemphix nattereri (Steindachner, 1963), including the stereological and quantitative evaluation of this cell type in the gonads. Ten adult males were collected in Nova Itapirema, São Paulo, Brazil, and submitted to morphological studies with light and transmission electron microscopy. The testis presents a great number of large cells with many brown granules and long cytoplasmic processes. The pigmented cells found in the testis are structurally similar to melanocytes, characterized by large amounts of melanosomes. The cells may be in intimate contact with the same cell type, with myoid cells surrounded by a large amount of collagen fibers, Leydig cells, and next to fibroblasts. The distribution and amount of extracutaneous melanocytes is variable when other organs and membranes are analyzed, allowing the establishment of species-specific patterns for the extracutaneous pigmentary system.

A Orientação Sexual na Revista Nova Escola

Este estudo teve por objetivo identificar no periódico Nova Escola artigos referentes a educação e orientação sexual, sistematizar e analisar essas produções. Para tanto foram analisados os 118 números publicados entre março de 1986 a dezembro de 1998. O estudo mostrou que a orientação sexual é um tema constantemente abordado pela revista e que a ênfase norteadora das reportagens é a indicação de normas, práticas e padrões de conduta pelas quais os professores podem-se pautar para a sua atuação em sala de aula.

Paracoccidioides brasiliensis (Lutz, 1908) isolado por meio de hemocultura em um paciente portadora de símdrome de imunodeficiência adquirida (SIDA)

A case of an AIDS-patient with positive blood culture for Paracoccidioides brasiliensis is reported. The patient was a 29 years old male born in Nova Londrina (Parana State, Brazil) who presented splenomegaly and fever of unknown origin. Three blood cultures were performed, each one of them for aerobic bacteria, mycobacteria and fungi. Cultures for aerobic bacteria and mycobacteria were negative. However, the yeast phase P. brasiliensis was isolated from two cultures in BHI agar, 20 days after inoculation in Negroni medium. The patient was classified in group V according to the Centers for Disease Control (CDC) criteria for AIDS, due to a Pneumocystis carinii pneumonia. Treatment was discontinued due to an individual decision of the patient on the second dose of amphotericin B. This antibiotic was replaced by ketoconazole in the daily dose of 800 mg. The patient died one year after the isolation of P. brasiliensis on blood culture.

Biofertilizante bovino, cobertura morta e revestimento lateral dos sulcos na produção de pimentão

The adoption of management practices that reduce water losses is essential to conserve moisture and improve soil temperature, especially in arid and semiarid environments of the Brazilian Northeast, characterized by high evapotranspiration and the adoption of irrigation with saline water, which harms growth and yield of commercial crops. Given these factories, an experiment was conducted in Nova Floresta, Paraiba, from August 2010 to February 2011 in Oxisoil, in order to evaluate the production of bell pepper and soil moisture in grooves with side trim, and application of biofertilizer and mulch cattle. The experimental design was randomized blocks with four replications using a factorial 2 x 2 x 2 for the ground beef with and without biofertilizer, with and without residues of sisal fiber (Agave sisalana), with and without the side facing the grooves, to reduce lateral water losses by infiltration of water with polyethylene plastic film. From the results, the lining of the lateral grooves provided higher values of soil moisture, number of fruits, fruit mass, plant production and productivity, bell pepper plants. It was also found that the combination of biofertilizer and mulch the ground beef remained wetter in the first 15 cm depth.

Sensoriamento remoto multifonte aplicado na detecção do fitoplâncton em águas interiores

Blooms of phytoplankton can be a risk to human health and aquatic biota, so the adoption of monitoring methods of phytoplankton and mechanisms for preventing its occurrence are needed. Thus, traditional monitoring methods could be more effective if complemented by approaches using the optical properties of phytoplankton pigments by means of Remote Sensing. In order to evaluate the potential of multi-scale remote sensing for detection of the phytoplankton activity, a study area was selected in Nova Avanhandava reservoir, located in the Tiete River, SP. For this analysis, hyperspectral field data and multispectral images of low and medium spatial resolution (Modis and RapidEye) were acquired and were related to indicator limnological variables of phytoplankton behavior; chlorophyll a and phycocyanin. The results show that a specific spectral band of RapidEye system (690-730 nm) allowed detect chlorophyll a and to evaluate the phytoplankton biomass, however hyperspectral data are needed to detect the phycocyanin pigment, indicative of cyanobacteria.
