OBJECTIVE To look for correlations between radiological patterns and CD4+ T cell counts in patients coinfected with tuberculosis and human immunodeficiency virus. METHODS Patients included were selected from among those presenting human immunodeficiency virus/tuberculosis coinfection and admitted to the Nereu Ramos Hospital, located in Florianópolis, Brazil, between January of 2000 and Decemb...

Dynamic responses of cardiac sodium-calcium exchange current to changes of cytoplasmic calcium and MgATP were monitored and analyzed in giant membrane patches excised from guinea pig myocytes. Secondary dependencies of exchange current on cytoplasmic calcium are accounted for in terms of two mechanisms: (a) The sodium-dependent inactivation process, termed I1 modulation, is itself strongly modu...

1. For any instance I1 of π1, I2 = f(I1) is an instance of π2 such that OPTπ2(I2) ≤ OPTπ1(I1). 2. For any feasible solution S2 of I2, S1 = g(I1, S2) (g maps S2 into an instance of I1) we have Costπ1(I1, S1) ≤ Costπ2(I2, S2). Note that OPTπ2(I2) ≤ OPTπ1(I1) ≤ Costπ1(I1, S1) ≤ Costπ2(I2, S2). Therefore, if there is an approximation factor ∆ for π2 then there is an approximation factor ∆ for π1 as...

In this paper we introduce and investigate I2-convergence, I∗ 2 -convergence, I2-limit points, and I2-cluster points of a double sequence in a fuzzy 2-normed linear space. We prove a decomposition theorem for I2-convergence of double sequences. The notions of I2-double Cauchy and I∗ 2 -double Cauchy sequence are defined, and some of their properties are studied.

(6) Let G be a column Y-constant line Y-increasing matrix over E2 T and i1, i2, j1, j2 be natural numbers. Suppose 〈i1, j1〉 ∈ the indices of G and 〈i2, j2〉 ∈ the indices of G. If (G◦ (i1, j1))2 = (G◦ (i2, j2))2, then j1 = j2. (7) Let G be a line X-constant column X-increasing matrix over E2 T and i1, i2, j1, j2 be natural numbers. Suppose 〈i1, j1〉 ∈ the indices of G and 〈i2, j2〉 ∈ the indices o...

Alternative splicing (AS) is one of the most significant components of the functional complexity of human UDP-glucuronosyltransferase enzymes (UGTs), particularly for the UGT1A gene, which represents one of the best examples of a drug-metabolizing gene regulated by AS. Shorter UGT1A isoforms [isoform 2 (i2)] are deficient in glucuronic acid transferase activity but function as negative regulato...

The purpose of this article is to describe and clarify a tool that is at the core of the definition phase of most quality improvement projects. This tool is called the critical to quality (CTQ) flowdown. It relates high-level strategic focal points to project objectives. In their turn project objectives are linked to and decomposed into CTQs, which are made operational in the form of measuremen...

                In order to determine the best developmental stage of three common bean cultivars (Talash, COS16 and Khomain) at which maximum seed quality is attained under different irrigation regimes (I1-irrigation after 60 mm, I2-irrigation after 80 mm and I3-irrigation after 100 mm evaporation from class A pan), a split plot experiment (using R.C.B. design) with 3 replications was conducte...

In most wheat growing moderate regions and especially in the north of Iran climate, is affected grain filling by several physical and abiotic stresses. In this region, grain filling often occurs when temperatures are increasing and moisture supply is decreasing. The experiment was designed in RCBD with split plot arrangements with four replications. Four irrigation treatments included (I0) no i...
