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.

Albright's syndrome: review of the literature and case report.

Albright's syndrome is characterized by the presence of polyostotic fibrous dysplasia, endocrinopathies and brown spots on the skin. In the present article the authors describe a case occurring in a 20-year-old female patient, who is currently being followed radiographically after a mandibular bone biopsy.

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.

Close Enough to One Another and Far Apart as Well´: The Intersection of Literature and History in Seamus Deane´s Reading in the Dark

This article analyses the intersection of narrative and history in Seamus Deane’s Reading in the Dark (1996). It uses the Benjaminian notions of memory, narration and experience to investigate how this novel creates a self through a language characterized by the absence of what it refers to. The analysis will eventually demonstrate that the tension between recollection and obliteration makes Literature and History converge as products of a narrative act.

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.

A presença da literatura/cultura portuguesas em periódicos paulistas - 1900-1922

Partindo-se do pressuposto de que existe uma interligação, por meio da presença da literatura/cultura portuguesa, entre Portugal e a cidade de São Paulo – no período de 1900-1922, caracterizado ainda como pré-modernista brasileiro –, a proposta deste texto dirige-se ao comentário de alguns periódicos (O Estado de S. Paulo; A Vida Moderna; O Pirralho), visto que “[...] há uma história da literatura que se projeta na cidade de S. Paulo; e há uma história da cidade de S. Paulo que se projeta na literatura.” (CANDIDO, 1975). Assim, pretende-se verificar como a presença da literatura/cultura portuguesa (principalmente autores canônicos do século XIX) repercutiu na vida social e intelectual da cidade de São Paulo, para melhor compreensão das formas de sociabilidade, bem como a caracterização das diferentes etapas percorridas pela literatura brasileira em São Paulo.

Os mortos de sobrecasaca e a formação do cânone literário nacional

Álvaro Lins (1912-1970), was an important literary critic of brazilian modernism that marked the twentieth century by the great influence of his writings. In 1963, he published Os Mortos de Sobrecasaca: obras, autores e problemas de literatura brasileira. Ensaios e estudos 1940-1960, that brings in the subtitle his concerns in building a balance on the modernist legacy to literature and culture in Brazil. This work makes possible a schematic view of the evolutionary process of literary production, because it indicates an exam about the twenty years of ripening of modernist proposals from a reflection that is organized as a history of Brazilian literature based on leading writers of the national literary canon.
