Effect of aging on the stability of ceramic foams prepared by thermostimulated sol-gel process
(Kluwer Academic Publ, 2003-01-01)
This work presents a new route of preparation of zirconium ceramic foams based on the thermostimulated sol-gel process. This method produces gelled bodies with up to 90% of porosity in the wet gel and can be used to make ...

Hallmarks of aging: An autophagic perspective
(Frontiers Media S.A., 2019-01)
Autophagy is a major protein turnover pathway by which cellular components are delivered into the lysosomes for degradation and recycling. This intracellular process is able to maintain cellular homeostasis under stress ...
Behavioral effects of LPS in adult, middle-aged and aged mice
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Acute infections lead to alterations in behavior, collectively known as sickness behavior. which includes reduction in locomotion, food ingestion, sexual and social behavior, environmental exploration, and sleep profile. ...
Aging voice: presbyphonia
(Springer, 2014-02-01)
Presbyphonia is a physiological process of aging voice that includes morphological changes in the coverage mucosa, muscle, and cartilage. We revised the morphological, endoscopic, and vocal acoustic changes that occur in ...
Coping processes that foster accommodation to loss in old age
(Routledge, 2020)
Aim: Flexible adjustment or accommodation to loss is healthy; however, little is known about how it can be achieved in old age. We sought to identify and characterize effective coping processes for achieving accommodation ...
Spontaneous eye blink analysis in the normal individual
(2005-12-01)
Purpose: Spontaneous eye blink activity in the primary eye position and its relationship to age and gender were assessed using digital image processing techniques to quantify blink opening and closing time. Methods: One ...
