Neutrophil interaction with inflamed postcapillary venule endothelium alters annexin 1 expression

Annexin 1 (ANX-A1) exerts antimigratory actions in several models of acute and chronic inflammation, This is related to its ability to mimic the effect of endogenous ANX-A1 that is externalized on neutrophil adhesion to the postcapillary endothelium. In the present study we monitored ANX-A1 expression and localization in intravascular and emigrated neutrophils, using a classical model of rat peritonitis, For this purpose, a pair of antibodies raised against the ANX-A1 N-terminus tie, able to recognize intact ANX-A1) or the whole protein tie, able to interact with all ANX-A1 isoforms) was used by immunofluorescence and immunocytochemistry analyses. The majority (similar to 50%) of ANX-A1 on the plasma membrane of intravascular neutrophils was intact. Extravasation into the subendothelial matrix caused loss of this pool of intact protein (to similar to6%), concomitant with an increase in total amount of the protein; only similar to 25% of the total protein was now recognized by the antibody raised against the N-terminus tie, it was intact). In the cytoplasm of these cells, ANX-A1 was predominantly associated with large vacuoles, possibly endosomes, In situ hybridization confirmed de novo synthesis of ANX-A1 in the extravasated cells. In conclusion, biochemical pathways leading to the externalization, proteolysis, and synthesis of ANX-A1 are activated during the process of neutrophil extravasation.

Knowledge-based risk management: Survey on Brazilian software development enterprises

A risks management, carried on in an effective way, leads the software development to success and may influence on the organization. The knowledge takes part of such a process as a way to help taking decisions. This research aimed to analyze the use of Knowledge Management techniques to the Risk Management in software projects development and the possible influence on the enterprise revenue. It had, as its main studying subject, Brazilian incubated and graduated software developing enterprises. The chosen research method was the Survey type. Multivariate statistical methods were used for the treatment and analysis of the obtained results, this way identifying the most significant factors, that is, enterprise's achievement constraining factors and those outcome achievement ones. Among the latter we highlight the knowledge methodology, the time of existence of the enterprise, the amount of employees and the knowledge externalization. The results encourage contributing actions to the increasing of financial revenue. © 2013 Springer-Verlag.

A observação da estrutura textual de livros e sua contribuição para a catalogação de assuntos em bibliotecas universitárias da UNESP

The indexing is a kind of description whose aim is to establish concepts expressed in a document and representing them according to a documentary language. There are elements that can contribute to a more complete selection of terms that will represent the document, like the observation of its textual structure and the context where the indexing professional acts. The analysis of the book textual structure can be carried out in a way that facilitates the indexing, as the professional can foresee the parts of the text where he localizes and identifies the more representative terms of the textual content. In such a way, it is intended to comprehend and inquire, with the applying of Verbal Protocol, the use that São Paulo libraries indexers do from the textual structure during the determination of subjects in such a way as to obtain the disclosure of their procedures, difficulties and restrictions through the externalization of thoughts during the recording of the indexing task. From the data analysis, it was possible to find out that the right hand page, the back of the title page, the chapters and other parts of the book s structure provided the greater number of terms, becoming the most important ones for the indexing task.

Centriole behaviour during meiosis of male germ cells of Dermatobia hominis (Diptera:Cuterebridae)

During the meiotic division of Dermatobia hominis spermatogenesis, the centrioles duplicate only in prophase I, giving rise to short cilia which are exposed on the cellular surface. In metaphase I they are internalized and distributed to the daughter cells. Consequently, the secondary spermatocytes have two centrioles which repeat the cycle of cilia externalization followed by internalization. The spermatids receive only one centriole, which changes into a basal body and originates a flagellum. This centriole behaviour seems to be a general feature in insect male germ cell meiosis.

A música associada às necessidades terapêuticas de pacientes com deficiência

The use of music and/or its elements (instruments, sound, rhythm, melody and harmony) in environments with people attended by public health centers, aims at promoting communication, facilitating the expression and the relationship in the first contact, hence favoring organization of standards and other relevant therapeutic objectives to assist physical, mental, social and cognitive needs of people, thus promoting the process of environmental adaptation, behavioral conditioning and social inclusion. The purpose of this project is to use music and its sound elements, as well as recreational activities, developed in stages called: socialization session, art workshop and complementary activities, with patients assisted at CAOE (Disabled People Dental Care Center) and their relatives. The objective is to provide them psychological wellbeing, inclusion to physical space, relaxation, stimulation of rhythmic and sonorous perceptions, memorization, emotions externalization, help and encouragement for the development of motor coordination during their daily activities of daily. Recreational activities, handling and contacting with musical instruments, broadcasting and producing sounds, stimulate cognitive capacity, interactivity and entertainment activities can greatly contribute to improve the behavioral reaction and adaptation of these patients, during their dental treatment.
