Ultrastructural features of the hypopharyngeal glands in the social wasp Polistes versicolor （Hymenoptera： Vespidae）

引用

Insect Science 2008年第3期15卷 277-284页

作者： Fabio Barros Britto flavio henrique Caetano Universidade Estadual Paulista Julio de Mesquita Filho Instituto de Bioci~ncias de Rio Claro - Depto. de Biologia Rio Claro SP Brazil

The wasps of the genus Polistes have been considered the key to understanding the evolution of social behavior in Hymenoptera. Several studies have shown that the development of organized insect societies was accompanied by the evolution of structures like exocrine glands, which became specialized to perform specific functions. This article investigates the ultrastructural and cytochemical features of the hypopharyngeal glands of Polistes versicolor. These glands have been studied in depth in social bees, where they occur only in nurses and produce the royal jelly. Our results＇ revealed that these glands basically did not vary among individuals or between sexes. They are constituted by spherical cells, each with a large nucleus and well-developed rough endoplasmic reticulum. Secretion vesicles are abundant, but lipid droplets were not observed, indicating that these glands may not have a role in pheromone synthesis. Acid phosphatase was detected in lysosomes, and also flee in the cytosol, but did not seem to be related with cell death. Thus, our results suggest that the hypopharyngeal glands ofP. versicolor may not have a specialized social role, but could produce digestive enzymes.

Materials Sciences and Applications 2011年第8期2卷 1058-1069页

作者： Janaina Aline galvao Barros Antonio Jedson Caldeira Brant Luiz henrique Catalani Institute of Chemistry University of Sao PauloSao PauloBrazil

PVP, a synthetic polymer and chitosan, a natural polymer are biocompatible and have presented a great variety of interesting properties for cosmetic, biomedical, pharmaceutical and biotechnological applications, Many alternatives to improve the polymer propeties has been made as bleeding polymers, for example. In this work, two different techniques of hydrogel attainment were used: one from mixtures of acid aqueous cosolutions of chitosan and PVP, whose resultant films and solutions were irradiated, afterwards, by ultraviolet radiation (λ = 254 nm), another one from the reaction of poly (N-vinyl-2-pyrrolidone-co-acrolein)-a novel copolymer synthesized in our biomaterials laboratory-and chitosan. In the first one alternatives it was possible produce hydrogels directly from mixtures of aqueous acidic co-solutions of both polymers. In the second one, the attainment of hydrogels from Schiff base has proved to be an effective methodology for the production of hydrogels, showing good values of gel content and swelling.

Superficial stains and irregularities of the enamelare generally what prompt patients to seek dental intervention to improve their smile. These stains or defects may be due to hypoplasia, amelogenesis imperfecta, mineralized white spots, or fluorosis, for which enamel microabrasion is primarily indicated. Enamel microabrasion involves the use of acidic and abrasive agents, such as with 37% phosphoric acid and pumice or 6% hydrochloric acid and silica, applied to the altered enamel surface with mechanical pressure from a rubber cup coupled to a rotatory mandrel of a lowrotation micromotor. If necessary, this treatment can be safely combined with bleaching for better esthetic results. Recent studies show that microabrasion is a conservative treatment when the enamel wear is minimal and clinically imperceptible. The most important factor contributing to the success of enamel microabrasion is the depth of the defect, as deeper, opaque stains, such as those resulting from hypoplasia, cannot be resolved with microabrasion, and require a restorative approach. Surface enamel alterations that result from microabrasion, such as roughness and microhardness, are easily restored by saliva. Clinical studies support the efficacy and longevity of this safe and minimally invasive treatment. The present article presents the clinical and scientific aspects concerning the microabrasion technique, and discusses the indications for and effects of the treatment, including recent works describing microscopic and clinical evaluations.

Baccharis dracunculifolia, popularly known in Brazil as “alecrim-do-campo”, is widely recognized for its therapeutic potential. The extract of its leaves is used for liver problems, stomach disorders and others. The objective of the present study was to perform a histochemical analysis of curimbata fish livers to evaluate the potential effects and risks of the ingestion of B. dracunculifolia. Thirty-two animals were divided into two experimental groups in duplicate: Control group (regular food) and B. dracunculifolia Treated group (food added with B. dracunculifolia). The fishes were collected on the 14th and 21st days after the treatment period of 21 days. The histological alterations were evaluated using the semiquantitative methods Mean Value of Alterations (MVA), Histopathological Alteration Index (HAI) and Image J®. HAI and MAV showed that the extract caused slight but statistically significant damages, widely distributed throughout the organ. The results showed significant hepatic alterations caused by the ingestion of B. dracunculifolia extract.

The fish Prochilodus lineatus (Characiformes, Prochilodontidae), in addition to being a good bioindicator, is also of economic and ecological importance with a broad distribution in the neotropics. Ecotoxicology examines the interaction between environmental chemistry and biota;and in this study we assess alterations of bile and glycogen levels in the fish liver, organ responsible for detoxification, biotransformation and storing nutrients, such as glycogen, and for secreting bile. Fish were separated in three groups to examine the damage caused by the exposure to waters from Lago Azul-Rio Claro-SP and containing diluted biodegradable detergents in comparison to a control group (chlorinated water from an artesian well of UNESP-Campus Rio Claro). A histological analysis was performed on HE and PAS stained sections. The identification of structural changes and the assessment of the area occupied by bile and glycogen were carried out with the software ImageJ, showing that the liver was affected morphologically (cell vacuolization, peripherals nuclei, for example) and problems in bile release and production and storage of glycogen.

Fish populations are sensitive to environmental impact resulting from many factors, as an introduction of exotic species, industrial or residual waste, oil spills, pesticides or other agents that can directly affect the ecology and species survival. Astyanax altiparanae is pelagic and active swimmer specie and can have serious implications on its way of life as changes in muscle structure of fish may occur since the presence of pollutants in the water. In this study we analyze the alterations in Muscle and collagen fibers of the pectoral muscles and pollutants exposed flows contained in water with biodegradable detergents, and water coming from the Blue Lake, River clear-SP (2o24'39"S, 47o33'39"E) diluted. Effects of these exposures were analyzed during the period of seven and thirty days. Compared with acclimatized fish (Astyanax altiparanae) with pure water from an artesian well, the muscle fibers morphology and collagen concentration on them have changed due to the exposure to urban pollutants and biodegradable detergents.

Particulate matter with an aerodynamic diameter below 2.5 μm (PM2.5), present in polluted air, has been associated with a large spectrum of health impairments, mainly because of its deep deposition into the lungs. Araraquara City (Southeast Brazil) is surrounded by sugar-cane plantations, which are burned to facilitate the harvesting;this process causes environmental pollution due to the large amounts of soot that are released into the atmosphere. In this work, the elemental composition of PM2.5 was studied in two scenarios, namely in sugar-cane harvesting (HV) and in non-harvesting (NHV) seasons. The sampling strategy included one campaign in each season. PM2.5 was collected using a dichotomous sampler (10 L·min-1, 24 h) with PTFE filters. Information concerning the bulk elemental concentration was provided by energy-dispersive X-ray fluorescence. Enrichment factor analysis indicated that S, Cl, K, Cr, Ni, Cu, Zn, As, Cd and Pb were highly enriched relative to their crustal ratios (to Al). Principal component analysis was used to get some insight about the sources of the elements. Principal component 1 (PC1) explained 30.5% of data variance. The elements that had high loading (>0.7) were: S, Cr, As, and Pb;these are associated with combustion of fossil fuels. In principal component 2 (PC2), Cl, Cu, Zn, and Cd showed high loadings;these elements are associated with biomass burning. The Ni concentration found is three times larger than the threshold of risk for lung cancer, as recommended by the World Health Organization.
