La Lonja que no fue. Reflexiones e hipótesis sobre el proyecto inicial de la Lonja de Valencia.

open access: yesAnales de Historia del Arte, 2012
La historia de la arquitectura se ha hecho a partir de los edificios construidos o, en algunos casos, con proyectos utópicos o no ejecutados. Con ello, sin embargo, estaremos al final de un recorrido que, muchas veces, nos impide reconocer los modelos y ...

Accuracy Evaluation of Ro-Ro and Ro-Pax Ships Arrival to the Ports

open access: yesTransNav, the International Journal on Marine Navigation and Safety of Sea Transportation, 2020
Ro-Ro and Ro-Pax ships works on basis of regular schedule and try keep this schedule as accurate as possible. In same time difficulties during Ro-Ro and Ro-Pax ships voyages like bad weather conditions, waiting time to entry in to port, ship's failures and others, sometime request more time as it was planned initially.

2D vanadium carbide MXenzyme to alleviate ROS-mediated inflammatory and neurodegenerative diseases

open access: yesNature Communications, 2021
Reactive oxygen species (ROS) are generated and consumed in living organism for normal metabolism. Paradoxically, the overproduction and/or mismanagement of ROS have been involved in pathogenesis and progression of various human diseases.

Melatonin: Awakening the Defense Mechanisms during Plant Oxidative Stress

open access: yesPlants, 2020
Melatonin is a multifunctional signaling molecule that is ubiquitously distributed in different parts of a plant and responsible for stimulating several physio-chemical responses to adverse environmental conditions. In this review, we show that, although

Reactive Oxygen Species (ROS) Regulates Different Types of Cell Death by Acting as a Rheostat

open access: yesOxidative Medicine and Cellular Longevity, 2021
Reactive oxygen species (ROS) are essential for cellular signaling and response to stress. The level of ROS and the type of ROS determine the ability of cells to undergo cell death.

Early redox activities modulate Xenopus tail regeneration. [PDF]

open access: yes, 2018
Redox state sustained by reactive oxygen species (ROS) is crucial for regeneration; however, the interplay between oxygen (O2), ROS and hypoxia-inducible factors (HIF) remains elusive.

IGF-1 protects SH-SY5Y cells against MPP+-induced apoptosis via PI3K/PDK-1/Akt pathway

open access: yesEndocrine Connections, 2018
Insulin-like growth factor (IGF)-1 is a well-known anti-apoptotic pro-survival factor and phosphatidylinositol-3-kinase (PI3K)/Akt pathway is linked to cell survival induced by IGF-1.
