Stress in parents of very low birth weight preterm infants hospitalized in neonatal intensive care units. A multicenter study
(Sociedad Argentina de Pediatría, 2015)
Introduction. The birth of a premature baby is a stressful event for parents. The objective of this study was to determine early stress in parents of very low birth weight infants (VLBWIs) hospitalized in 12 neonatal ...
Immediate and long-term effects of psychological stress during adolescence in cardiovascular function: comparison of homotypic vs heterotypic stress regimens
Adolescence has been proposed as an ontogenic period of vulnerability to stress. Nevertheless, the impact of stressful events during adolescence in cardiovascular activity is poorly understood. Therefore, the purpose of ...
Polymerization stress, shrinkage and elastic modulus of current low-shrinkage restorative composites
(ELSEVIER SCI LTD, 2010)
Objective. To compare currently available low-shrinkage composites with others regarding polymerization stress, volumetric shrinkage (total and post-gel), shrinkage rate and elastic modulus. Methods. Seven BisGMA-based ...
SsNAC23, a member of the NAC domain protein family, is associated with cold, herbivory and water stress in sugarcane
(Elsevier Ireland LtdClareIrlanda, 2005)
Low-level laser therapy (808 nm) reduces inflammatory response and oxidative stress in rat tibialis anterior muscle after cryolesion
Background and Objective Muscle regeneration is a complex phenomenon, involving coordinated activation of several cellular responses. During this process, oxidative stress and consequent tissue damage occur with a severity ...
Low salt stress affects physiological parameters and sugarcane plant growth
Sugarcane is a renewable source for biofuel production and widely grown in tropical regions of the world. However, its cultivation might be limited in regions with soils affected by high level of soluble salts. This work ...

Nutrition for broilers under high temperatures is extremely important for brazilian broiler chicken industry because the amounts of consumed nutrients and environmental temperature have great effects on bird performance ...
Application of acoustoelasticity to evaluate stress relaxation in API 5L x70 steel for pipelines
(Amer Soc Nondestructive TestColumbusEUA, 2005)
On the determination of stress profiles in expanded austenite by grazing incidence X-ray diffraction and successive layer removal
Surface layers of expanded austenite resulting from nitriding typically exhibit large gradients in residual stress and composition. Evaluation of residual-stress profiles is explored by means of grazing incidence X-ray ...
