RESUMO No consórcio entre hortaliças pouco se conhece sobre as respostas fisiológicas. Conhecer o comportamento fisiológico é fundamental para avaliar a eficiência dessas espécies. Sendo assim, objetivou-se fisiológicas da rúcula consorciada com nirá sob diferentes arranjos espaciais e épocas de cultivo. O experimento foi conduzido no delineamento em blocos casualizados, esquema parcela subdivi...

The concentration of soluble interleukin 2 receptor (IL-2R) was determined in the serum of 54 patients with systemic lupus erythematosus (SLE) by an enzyme linked immunosorbent assay (ELISA) using two monoclonal antibodies with the IL-2R. Concentrations of soluble IL-2R in the serum of the patients with SLE (study group) were significantly higher than in 20 normal subjects (control group). The ...

In spite of the ease of computation of Cronbach Coefficient Alpha, its misconceptions and mis-applications are still widespread, such as the confusion of consistency and dimensionality, as well as the confusion of raw Alpha and standardized Alpha. To clarify these misconceptions, this paper will illustrate the computation of Cronbach Coefficient Alpha in a step-by-step manner, and also explain ...

The IL-2 receptor (IL-2R) gamma chain, the so-called common gamma (gamma(c)) chain, which is shared with multiple cytokine receptors, plays important roles in the immune system. Here we assessed the immunosuppressive ability of mAb specific for the gamma(c) chain in induction of cytotoxic T lymphocytes (CTL) and allograft rejection in combination with mAb specific for the alpha and beta chains ...

2,3-dihydroxy-2-methylbutyric acid, also known as 2,3-dimethylglyceric constitutes the acyl and/or alcoholic moiety of many bioactive natural esters. Herein, we describe a chemoenzymatic methodology which gives access to all four possible stereoisomers acid ethyl ester. The racemic ?-acetolactate, produced by N-heterocycle carbene (NHC)-catalyzed coupling pyruvate and methylacetoin was employed...

A psychometrically sound measurement instrument is crucialy in understanding needed athletes’ psychological profile. Among indices of a psychometrically sound instrument are its factor structure and internal consistency. The present study examined the factorial validity and reliability of the Malaysian version of the Revised Competitive State Anxiety Inventory 2 using confirmatory factor analys...

introduction: antimicrobial peptides as the body's defense strategy play an important role in resistance against infection of microorganism. these peptides are able to modulate the immune and inflammatory processes through the production of defensive molecules. therefore, the modulatory effects of brevinin-2r, an antimicrobial peptide extracted from the skin of the frog (rana ridibunda), w...

Serum concentrations of soluble interleukin 2 receptors (sIL 2R) were measured by an enzyme-linked immunosorbent assay (ELISA) in 30 patients with adult T cell leukemia (ATL), in 9 patients with other hematopoietic malignancies, and in 17 asymptomatic individuals seropositive for human T cell leukemia virus type I (HTLV-I). Sixty HTLV-I seronegative, age-matched controls showed a normal range o...

The plasma soluble interleukin-2 receptor (sIL-2R) level was higher in 137 patients with acute leukemia (1,489 +/- 1,798 U/ml, including 98 cases of acute myeloid leukemia (AML), 1,063 +/- 1,414 U/ml, and 39 cases of acute lymphoblastic leukemia (ALL), 2,561 +/- 2,194 U/ml), compared to 49 normal control subjects, 421 +/- 151 U/ml). The ALL patients showed elevated plasma sIL-2R levels more fre...
