We evaluated whether kinins exert a protective action against the development of two-kidney, one clip (2K1C) hypertension, a model characterized by an activated renin-angiotensin system in the ischemic kidney and increased expression of the bradykinin (BK) B2 receptor in the contralateral kidney. BK B2-receptor knockout (B2-/-), wild-type (B2+/+), and heterozygous (B2+/-) mice underwent clippin...

Abstract In most developing countries non-irrigation status often dominates adoption of traditional and modern irrigation technology. In this paper, we study the effect of production risk on irrigation technology choice among small-scale farmers in Chile, applying sample selection and discrete choice models. We find that more educated farmers, with credit access, receiving extension services, a...

PURPOSE To demonstrate the antimicrobial properties of riboflavin/UVA (365 nm) against common pathogens. METHODS One group of bacteria (Pseudomonas aeruginosa [PA], Staphylococcus aureus [SA], and Staphylococcus epidermidis [SE]) was tested by using Kirby-Bauer discs with (1) empty disc (Control - C); (2) riboflavin 0.1% (B2); (3) riboflavin 0.1% previously activated by UVA (B2'); (4) UVA alo...

Objective: To evaluate avidity of IgG anti-b2-glycoprotein I antibodies (anti-b2-GPI) in patients with antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE) in relation to thrombosis, and to demonstrate a possible affinity maturation of IgG anti-b2-GPI during the disease course. Methods: 64 sera from 32 patients (18 with primary or secondary APS, 14 with SLE without APS) and th...

[1] In this study, two parameterizations for different irrigation techniques have been implemented in a regional climate model. These implementations allow for a comparative study of water use and land–atmosphere interactions associated with traditional flood irrigation—a widespread but highly water-inefficient practice—and water-conserving drip irrigation. Both parameterizations yield realisti...

Lamins B1 and B2 (B-type lamins) have very similar sequences and are expressed ubiquitously. In addition, both Lmnb1- and Lmnb2-deficient mice die soon after birth with neuronal layering abnormalities in the cerebral cortex, a consequence of defective neuronal migration. The similarities in amino acid sequences, expression patterns, and knockout phenotypes raise the question of whether the two ...

Calystegines were isolated from the root cultures of Physalis divaricata, P. pubescens, P. philadelphia,and P. philadelphia (solanaceae). Calystegines of P. divaricata were identified as calystegine A3, A5, B1 and B2, with concentrations of 6.99, 4.41, 8.52, and 14.7 ?g/g in fresh mass, respectively. Root cultures of P.pubescens contain calystegine A3, B1 and B2, P. philadelphia only contains ...

Regulation of the constitutively expressed type 2 bradykinin (B2) receptor, which mediates the principal actions of bradykinin, occurs at multiple levels. The goal of the current study was to determine whether the human B2 3'-untranslated region (UTR) has effects on gene expression, with particular focus on the variable number of tandem repeats (B2-VNTR) polymorphic portion of the 3'-UTR and it...
