Differential roles of prelimbic and infralimbic cholinergic neurotransmissions in control of cardiovascular responses to restraint stress in rats
(2022-04-01)
Previous studies showed a prominent role of the medial prefrontal cortex (mPFC), especially the prelimbic (PL) and infralimbic (IL) subregions, in behavioral and physiological responses to stressful stimuli. Nevertheless, ...
Stress, sintomas físicos, psicológicos e enfrentamento de situações estressoras em profissionais da sáude que atuam em hospitais
(Universidade Estadual Paulista (UNESP), 2014)
A mechanistic stress model of protein evolution accounts for site-specific evolutionary rates and their relationship with packing density and flexibility
(BioMed Central, 2014-04)
BACKGROUND: Protein sites evolve at different rates due to functional and biophysical constraints. It is usually considered that the main structural determinant of a site’s rate of evolution is its Relative Solvent ...
Predicting Posttraumatic Stress Symptom Prevalence and Local Distribution after an Earthquake with Scarce Data
(2017)
After a major earthquake, the assignment of scarce mental health emergency personnel to different geographic areas is crucial to the effective management of the crisis. The scarce information that is available in the ...
Thiol oxidation by nitrosative stress: Cellular localization in human spermatozoa
(Informa Healthcare, 2016-09)
Peroxynitrite is a highly reactive nitrogen species and when it is generated at high levels it causes nitrosative stress, an important cause of impaired sperm function. High levels of peroxynitrite have been shown to ...
Oxidative stress in the local and systemic events of apical periodontitis
(Frontiers Media SA, 2017)
Oxidative stress is involved in the pathogenesis of a variety of inflammatory disorders. Apical periodontitis (AP) usually results in the formation of an osteolytic apical lesion (AL) caused by the immune response to ...
Oxidative stress in tumor microenvironment -- Its role in angiogenesis
(2008)
The tumor angiogenesis process is believed to be dependent on an "angiogenic switch" formed by a cascade of biologic events as a consequence of the "cross-talk" between tumor cells and several components of local ...
An engineering methodology to assess effects of weld strength mismatch on cleavage fracture toughness using the Weibull stress approach
(SPRINGER, 2010)
This work describes the development of an engineering approach based upon a toughness scaling methodology incorporating the effects of weld strength mismatch on crack-tip driving forces. The approach adopts a nondimensional ...
Determination of potential risk of heat stress of cattle in four locations of Central and Southern Chile
