Se evaluaron los parámetros agronómicos de Tithonia diversifolia por efecto cuatro alturas corte (AC) desde el suelo (AC1: 0 cm, AC2: 10 AC3: 20 AC4: 30cm), con replicas cada una, durante 55 días. Los brotes/macollo, hojas/brote y hojas/macollo fueron mayores (p<0.05) en AC1. Sin embargo, número hojas/mata brotes/mata AC2, AC3 AC4. El peso forraje verde (FV)/macollo fue mayor AC1; aunque FV/...

Fragments of the African cassava mosaic virus (ACMV) genome, cloned upstream of the beta-glucuronidase (GUS) reporter gene in an expression cassette, were analysed for their ability to direct complementary-sense gene expression in tobacco protoplasts by measuring GUS activity. Five arbitrary domains (A-E) have been designated that contribute to the expression of AC1 (replication-associated prot...

Ca-stimulated adenylyl cyclases (ACs) transduce neuronal stimulation-evoked increase in calcium to the production of cAMP, which impinges on the regulation of many aspects of neuronal function. Type 1 and type 8 AC (AC1 and AC8) are the only ACs that are directly stimulated by Ca. Although AC1 function was implicated in regulating reference spatial memory, the function of AC8 in memory formatio...

Pi (pi) and kappa (kappa) statistics are widely used in the areas of psychiatry and psychological testing to compute the extent of agreement between raters on nominally scaled data. It is a fact that these coefficients occasionally yield unexpected results in situations known as the paradoxes of kappa. This paper explores the origin of these limitations, and introduces an alternative and more s...

INTRODUCTION Pharmaceutical risk minimization programs involve interventions designed to support safe and appropriate use of medicines. Currently, information regarding the evaluation of these programs is not publicly reported in a standardized and transparent manner. To address this gap, we developed and piloted a quality reporting checklist entitled the Reporting recommendations Intended for ...

Objective: To investigate the effect of ascorbic acid (AC) on the etomidate (ETO)-induced inhibition of adrenocortical function. Methods: The rabbits were randomly divided into the etomidate (ETO), ETO+AC1 [ETO+AC (275 mg/kg)] and ETO+AC2 [ETO+AC (550 mg/kg)] groups. The rabbits were anaesthetised by ear vein injection of ETO (1.0 mg/kg), and the anaesthesia was maintained by three ear vein inj...

Nine membrane-bound mammalian adenylyl cyclases (ACs) have been identified. Type 1 and 8 ACs (AC1 and AC8), which are both expressed in the brain and are stimulated by Ca2 / calmodulin (CaM), have discrete neuronal functions. Although the Ca2 sensitivity of AC1 is higher than that of AC8, precisely how these two ACs are regulated by Ca2 /CaM remains elusive, and the basis for their diverse phys...

Compartmentation of cAMP signaling been demonstrated to be attributable to the structural association of protein kinase A (PKA) (via association with A-kinase anchoring proteins [AKAPs]) with phosphodiesterase and AKAP-dependent effector molecules. However, other mechanisms contributing to compartmentalization have not been rigorously explored, including the possibility that different isoforms ...
