Richness and abundance of granivorous vertebrates determine acorn removal patterns in a human modified oak forest
(2018)"Most forests of the Earth have been affected by human activities and this can alter the plant-animal interactions on which depend the functional integrity of these ecosystems. In this study, we assessed the relationships ... -
Tissue carbon concentration of 175 Mexican forest species
(2017)"Reliable calculations of carbon stocks in forest ecosystems are crucial for proper implementation of global warming mitigation policies. Accurate estimations depend upon applying the correct factor of carbon (C) concentration for ... -
Numerical computation of Lyapunov matrices for integral delay systems
(2017)"This paper focuses on the problem of computing Lyapunov matrices for integral delay systems. It is shown that these Lyapunov matrices cannot be computed by means of the existing methods for Lyapunov matrices of differential ... -
Expression analysis of the Arabidopsis thaliana AtSpen2 gene, and its relationship with other plant genes encoding Spen proteins
(2017)"Proteins of the Split ends (Spen) family are characterized by an N-terminal domain, with one or more RNA recognition motifs and a SPOC domain. In Arabidopsis thaliana, the Spen protein FPA is involved in the control of ... -
On computing estimates of the attraction region for a class of nonlinear time-delay systems
(2006)"In this paper, initial estimates of the attraction region for a class of nonlinear time delay systems are proposed. The approach is constructive, and make use of an appropiate Lyapunov-Krasovskii functional. Several ... -
Functional responses of recently emerged seedlings of an endemic Mexican oak (Quercus eduardii) under climate change conditions
(2018)"Background: Climate change will increase temperature and reduce rainfall across temperate forests of Mexico. This can alter tree establishment dynamics within forest and in neighbouring man-made clearings. Hypotheses: ... -
Hidrocoria en semillas de Agave victoriae-reginae T. Moore, especie en peligro de extinción: Morfología y anatomía como facilitadores de la hidro-dispersión y germinación
(2017)"Agave victoriae-reginae es una especie endémica del Desierto Chihuahuense y crece sobre paredes en cañones. Posee semillas aplanadas que pueden ser dispersadas durante eventos episódicos de inundación. La presente ... -
Efecto de la densidad de semillas en la germinación de tres especies del género Astrophytum (Cactaceae)
(2013)"Se colectaron frutos de poblaciones naturales de Astrophytum capricorne, A. myriostigma y A. ornatum en Coahuila, Durango e Hidalgo, respectivamente, con el objetivo de evaluar el efecto de la agrupación de semillas en ... -
Escontria chiotilla (Cactaceae): fruit development, maturation and harvest index
(2015)"Introduction. The edible fruit of jiotilla (Escontria chiotilla (Weber) Rose), a cactus endemic to Central Mexico, mature asynchronously and are characterized by the presence of bracts in the fruit peel (pericarpel). In ... -
Modeling the disintegration process in anaerobic digestion of tannery sludge and fleshing
(2017)"Mathematical modeling of anaerobic digestion (AD) is widely acknowledged as a powerful tool to v of the process and to support full-scale plant design, operation and optimization. In this work, a modified version of the ... -
The sole DNA ligase in entamoeba histolytica is a high-fidelity DNA ligase involved in DNA damage repair
(Frontiers Media S.A., 2018)"The protozoan parasite Entamoeba histolytica is exposed to reactive oxygen and nitric oxide species that have the potential to damage its genome. E. histolytica harbors enzymes involved in DNA repair pathways like Base ... -
Structural elucidation and evaluation of multidrug-resistance modulatory capability of amarissinins A–C, diterpenes derived from Salvia amarissima
(2016)"Three new diterpenes (amarissinins A-C, 1–3) containing several oxygenated functionalities were isolated from the leaves and flowers of Salvia amarissima. The structures of these compounds were established through the ... -
Smilax aristolochiifolia root extract and its compounds chlorogenic acidand astilbin inhibit the activity of alpha-amylase and alpha-glucosidase enzymes
(2018)"Regulating activities of -amylase and -glucosidase through the use of specific inhibitors is a main strategy for controlling type 2 diabetes. Smilax aristolochiifolia root decoctions are traditionally used in Mexico as ... -
Antioxidant activity and in vitro antiglycation of the fruit of Spondias purpurea
(2018)"Hyperglycemia in diabetes mellitus causes irreversible life-threatening micro- and macrovascular complications. There is evidence that the glycation reaction leads to a chemical modification of the proteins contributing ... -
Renal damage in the metabolic syndrome (MetSx): Disorders implicated
(2018)"The prevalence of metabolic syndrome is increasing worldwide and has become a risk factor for the development of chronic kidney disease. The complex linkage between metabolic syndrome and chronic kidney disease is under ... -
Morphometric and hypsometric analysis in the Tierra Nueva Basin, San Luis Potosí, México
(2017)"In areas with long periods of drought, it is essential to implement strategies to manage the available water resource. Tierra Nueva Basin is affected by this situation, consequently the farm production and livestock ... -
Up-flow anaerobic sediment trapped (UAST) reactor as a new configuration for the enrichment of anammox bacteria from marine sediments
