Dynamics between infectious diseases with two susceptibility conditions: a mathematical model
(2019)This paper presents a novel epidemiological transmission model of a population affected by two different susceptible-infected-susceptible infectious diseases. For each disease, individuals fall into one of the two ...

Dynamics of a modified Leslie-Gower predation model considering a generalist predator and the hyperbolic functional response
; ; Rojas, Alejandro
; (2019)
In the ecological literature, many models for the predator-prey interactions have been well formulated but partially analyzed. Assuming this analysis to be true and complete, some authors use that results to study a more ...

Dynamics of financial markets and transaction costs: A graph-based study
(2016)In financial markets,trading patterns influence the behaviour of arbitrage, surveillance, risk management and pricing returns. The analysis of these patterns is important for defining policies in financial regulation as ...

Dynamics of global remittances: A graph-based analysis
(2017)Human migration is an increasing world-wide phenomenon by which people leave their homeland to find better living conditions. This phenomenon entails financial issues for host countries. One of these issues are remittances. ...

Dynamin‑2 R465W mutation induces long range perturbation in highly ordered oligomeric structures
(2020)High order oligomers are crucial for normal cell physiology, and protein function perturbed by missense mutations underlies several autosomal dominant diseases. Dynamin-2 is one of such protein forming helical oligomers ...

Early effects of mycorrhizal fungal inoculum and fertilizer on morphological and physiological variables of nursery-grown Nothofagus alessandrii plants
(2023)Nothofagus alessandrii (ruil) is an endangered relict species, endemic to the Mediterranean area of Chile, and one of the most threatened trees in the country. Its natural distribution area has been greatly reduced by the ...

Early IGF-1 gene therapy prevented oxidative stress and cognitive deficits induced by traumatic brain injury
(2021)Traumatic Brain Injury (TBI) remains a leading cause of morbidity and mortality in adultsunder 40 years old. Once primary injury occurs after TBI, neuroinflammation and oxidativestress (OS) are triggered, contributing to ...

Early left atrial dysfunction is associated with suboptimal cardiovascular health
(2020)Aims: Two‐dimensional speckle‐tracking echocardiography can assess left atrial (LA) function by measuring atrial volumes and deformation parameters (strain, strain rate). This cross‐sectional analysis explores the association ...

Early motor reactivity to observed human body postures is affected by body expression, not gender
(2020)The early response to emotional stimuli involves a transient suppression of motor reactivity to favor monitoring of emotionally relevant information. Using transcranial magnetic stimulation (TMS), we have previously shown ...
-
Early regulation of corticosteroid receptor expression in rainbow trout (Oncorhynchus mykiss) gills is mediated by membrane-initiated cortisol signaling
(2023)Cortisol is a key stress-related hormone involved in the physiological adjustments of fish. In gills, cortisol contributes to acclimatization to changes in environmental salinity, promoting both ion uptake or salt excretion. ...

Early right motor cortex response to happy and fearful facial expressions: a TMS motor-evoked potential study
(2021)The ability to rapidly process others’ emotional signals is crucial for adaptive social interactions. However, to date it is still unclear how observing emotional facial expressions affects the reactivity of the human motor ...
