Interleukin 6 (11-6) is a multifunctional cytokine important in the inflammatory response. Its potential role as an antitumor agent has been suggested by its demonstrated activity in a variety of tumor models. The mechanism of antitumor activity has been proposed to be its en hancement of cytotoxic T-cell function. In the current work we demon strate clear antitumor activity for this cytokine i...

Mice dually infected with murine sarcoma virus (Moloney) [MSV(M)] and Guaroa virus (GV), an arbovirus of the Bunyamwera group, showed enhanced MSV(M) infection, reflected by progressive tumor growth, reduced median survival time, increased virus yield from tumor, and increased mortality with tumor as compared to mice inoculated with MSV(M) alone. Temporal studies indicated that GV-mediated enha...

BACKGROUND The purpose of this study is to investigate the efficacy of emotionally fo- cused therapy (EFT-C) on promoting marital adjustment of infertile couples with marital conflicts by improving quality of life. MATERIALS AND METHODS This is a semi-experimental study with a pre- and post-test design in which 30 infertile couples (60 individuals) were chosen by purposive sampling. Couples w...

An indole alkaloid tumor promoter, dihydroteleocidin B, was able to modulate a membrane property of 3T3-L1 preadipocytes, showing an almost complete reduction of epidermal growth factor binding capacity. This receptor modulating potency of dihydroteleocidin B, was 10 times that of a phorbol ester tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA). Dihydro teleocidin B, however, had littl...

Objective: to analyze based on the practitioners' discourse, the way they organize their practices confronting situations of intra-family violence against children and adolescents. Method: qualitative research carried out with 15 professionals who work in social and health services located in the southernmost of Brazil. Data were collected through semi-structured interviews, performed at the ...

A novel design of an electromagnetic bandgap (EBG) structure based on the uniplanar compact EBG (UCEBG) concept is proposed in this paper. The structure is realized by inserting splitring slots inside two reversely connected rectangular patches, which is known as a split-ring slotted electromagnetic bandgap (SRS-EBG) structure. The bandgap properties of the EBG structure are examined by the sus...

Resumen. Las grandes cantidades de información textual que actualmente se generan y almacenan digitalmente, junto con la dificultad que existe para analizarla, hace necesario el desarrollo de herramientas que faciliten este trabajo. Existen diferentes campos en las Ciencias de Computación y la Lingǘıstica que en conjunto posibilitan el desarrollo de este tipo de herramientas; en particular una ...

Control over the optical near field is a pillar stone of material processing,PI microscopy ,121 and biosensingl :1 1 at the submicrometer scale. The same applies to scanning probe techniques,II AJ which produce an impressive spatial resolution, and to colloidallithographyl' l for casting large periodic nanostructure arrays. However, imaging near-field distributions with subwavelength detail[fi ...
