Root-secreted phytochem.cals m.diate m.ltiple interactions in the rhizosphere. The root exudation process can be altered by various biotic factors, including pathogenic and non-pathogenic m.crobes, and abiotic factors like tem.erature and soil m.isture. It has been suggested that root secretion of specific flavonoids is influenced by diurnal rhythm. （by light or dark） but a com.rehensive analysis of the overall secretion of phytochem.cals in response to diurnal rhythm. has not been studied. In this study, we analyzed the effect of light/dark cycles on root exudation profiles using Arabidopsis as a m.del plant. Our results reveal that the root secretion of phytochem.cals is partly regulated by the diurnal light cycle and follows two m.in patterns of secretion：（1） the large m.jority of phytochem.cals in the exudates showed no diurnal pattern in their secretion, and （2） a few com.ounds showed a diurnal pattern in their secretion： three com.ounds increased in secretion only under light; two com.ounds increased in secretion only while it was dark; and two com.ounds increased in secretion during the transition from.dark to light. Root-specific ABC transporters have been im.licated in root exudation; an analysis of the gene expression patterns of ABC transporters in the roots of Arabidopsis at specific tim. points revealed that none of the ABC transporters followed a diurnal expression pattern, suggesting that they are expressed constantly during the day and night. Sim.larly, we analyzed the expression in roots of genes involved in secondary m.tabolite biosynthesis and found that som. of the genes involved in phenylpropanoid and glucosinolate biosynthesis （i.e. 4-coum.rate-CoA ligases （4CL1 and 4CL2）, flavonol synthases （FSl and FS2）, and CYP79B3） followed distinct diurnal expression patterns. Overall, we have discovered that while root exudation of the m.jority of phytochem.cals is constitutive, the secretion of a few com.ounds follows a diurnal rhythm. which is in accor

Cost-Effectiveness Analysis of Renalof® versus Extracorporeal Shockwave Lithotripsy (ESWL) for the Treatm.nt of Kidney Stones ≤ 1 cm.in Nicaragua

作者： m.lida m. Aguilar Cham.rro Sergio vargas Collado Leslie Pérez Ruíz David m.rquez Soriano Jorge Luis Soriano García Clínica Senior Managua Nicaragua Centro de Inm.nología m.lecular Havana Cuba Catalysis S.L. Madrid Spain

Objectives: To assess the efficiency in term. of cost-effectiveness (CE) of oral Renalof® treatm.nt versus extracorporeal shockwave lithotripsy (ESWL) in the treatm.nt of kidney stones ≤ 1 cm.in Nicaragua. m.thods: A cost-effectiveness econom.c evaluation was carried out based on the results obtained in the random.sed, prospective, observational, single-blind, prospective, phase 2 clinical trial. Cost-effectiveness and the increm.ntal cost-effectiveness ratio (ICER) were calculated. Econom.c data were obtained from.the Econom.cs Departm.nt of Clínica Senior in m.nagua, Nicaragua. The m.netary cost was expressed in US dollars (USD). Results: Treatm.nt with Renalof® yielded a CE of $1,323.08/% rem.ssion, while ESWL was $9,498.54/% rem.ssion. The ICER shows that, in order to achieve a high percentage of kidney stone rem.ssion with ESWL, an extra $4,734.70 per patient m.st be invested. Conclusions: The use of Renalof® is shown to be a m.re cost-effective option than ESWL. It is recom.ended for the treatm.nt of kidney stones ≤ 1 cm.in size.
