Influence of physical and chemical factors during foraging and culture of the symbiont fungus in Atta sexdens rubropilosa (Hymenoptera : Formicidae)

The aim of this paper is to investigate the influence of physical and chemical factors on transport and use of substrate for Atta sexdens rubropilosa workers. Three types of rectangular fragments were used to study the physical influence factors: filter paper with paraffin, filter paper without paraffin and polyester film. To study the chemical factors, some fragments were impregnated with organic extract of orange albedo, others were soaked with soybean oil and for the remaining ones nothing was applied. The following parameters were evaluated: (i) attractiveness of substrate for transport and number of loading workers per treatment; (ii) foraged material incorporation; (iii) rejection by numbers of fragments deposited in the garbage or beside the fungus garden. All the polyester film fragments carried out to the fungus garden were subsequently rejected. We verified that chemical factors of the substrate were more quickly detected by the workers, whereas physical factors were used as a criterion in the decision-making to reject or accept the substrate collected.

Bone Marrow'S Harvest in The Coxal Tuberosity for Isolation and Culture of Mesenchymal Stem Cells of Buffaloes (Bubalus Bubalis)

Several studies with mesenchymal stem cells (MSCs) have been developed in many species because of its ability to differentiate into other mesoderm lineages, capacity of self-regeneration, low immunogenicity, paracrine, anti-inflamatory, immunomodulatory and antiapoptotic effects which make then a promissory source to be used in therapeutic strategies. The aim of this study is to report the technique of harvest of bone marrow (BM) in the coxal tuberosity (CT) of buffaloes. For this, the animals were selected, identified and contained in a stock. Then trichotomy was performed in the region corresponding to the CT. After identifying the anatomic site it was performed antisepsis, local anesthetic block and introduction of a myelogram's needle (Lang(R)) for BM aspiration. Once the needle was firmly fixed in the CT, the mandril was removed and proceeded to BM aspiration with a syringe (20 mL) containing 1 ml of heparin at 1000 IU / mL and 1 mL of PBS. After the collection, each sample collected was manually homogenized, identified and referred to the LRACT - FMVZ / UNESP-BRAZIL for the correct processing. The anatomical site tested showed to be an alternative site of harvest of BM once provided the appropriate isolation and culture of the mononuclear fraction. Moreover, the procedure was performed without difficulty and with great security. Based on this, it can be conclude that CT is an excellent anatomical site for isolation and culture of MSCs and the proposed technique is viable and feasible to be held in buffaloes.

The use of a mixture of somatic and culture filtrate antigens in the evaluation of the immune response to Paracoccidioides brasiliensis

Three Paracoccidioides brasiliensis antigens, namely a culture filtrate preparation, a somatic antigen and a mixture of equal parts of the two, were tested by two serological techniques against sera from patients with paracoccidioidomycosis, and in an in vivo delayed hypersensitivity model in mice. The antigen mixture was more sensitive than the two individual antigens for the evaluation of humoral and cellular immune response to P. brasiliensis, both in man and in experimental animals.

The Magic Toyshop: A narrativa imagética como processo de recriação

Because it belongs to a cultural practice, the adaptation of a novel into a feature film will always exist within a context and, for being subject to changes, corresponding modifications in the political sphere and even variations in the meaning of the story may occur. This seems to be precisely the result of the transformation of Angela Carter's second novel, The Magic Toyshop, into the homonymous film, directed by David Whealtey in 1987. Removed from the context of the book's production and publication, a crucial period of questioning about the importance of women in society and culture, the plot created by the English author in the sixties, rewritten two decades later, with the author herself as the script writer, seems to have acquired another meaning during this time. Although the film maintains the same plot of the novel, the political engagement visibly present in the narrative, namely Carter's critical stance about the model of patriarchal society, seems to lose its strength, highlighting now its fantastic character. Briefly discussing issues such as loyalty and betrayal of one gender to another, we seek in this paper to observe the film, based on the re-writers perspective, in other words, the prospects of both writer and director, as a process of rebuilding the story. In this dialogue, the script was also used as an intertext for a better understanding of this process.
