(2007)Skeletal muscle is a highly plastic tissue with a remarkable capacity to adapt itself to challenges imposed by contractile activity. Adaptive response, that include hypertrophy and activation of oxidative mechanisms have ...
-
(Nature Publishing Group, 2018)How organisms adapt to unfavorable environmental conditions by means of plasticity or selection of favorable genetic variants is a central issue in evolutionary biology. In the Maipo River basin, the fish Basilichthys ...

(Optical Society of America, 2017)In the last ten years, the technology of differential geometry, ubiquitous in gravitational physics, has found its place in the field of optics. It has been successfully used in the design of optical metamaterials through ...
-
(Elsevier Ltd, 2017)Objective: In Aggregatibacter actinomycetemcomitans, different serotypes have been described based on lipopolysaccharide (LPS) antigenicity. When T lymphocytes were stimulated with these serotypes, different patterns of ...
-
(Universidad de Chile, 2020)This thesis has two main purposes: first, we shall compare continuous and discrete trajectories associated to a differential inclusion governed by the sum of a maximally monotone operator with a cocoercive operator and ...

(2009)Protein kinase CK2 is a serine/threonine kinase expressed in organisms from yeast to human and is composed of a catalytic subunit (α or α') and a regulatory subunit (β) forming a holoenzyme with the possible subunit ...
-
(Impact Journals LLC, 2018)© Andaur et al. Enhanced radiosensitivity at low doses of ionizing radiation (IR) (0.2 to 0.6 Gy) has been reported in several cell lines. This phenomenon, known as low doses hyperradiosensitivity (LDHRS), appears as an ...
-
(Elsevier, 2014)Progression of RNA interference-based gene silencing technologies for the treatment of disorders of the central nervous system (CNS) depends on the availability of efficient non-toxic nanocarriers. Despite advances in ...
-
(Elsevier, 2020)During spatial navigation, some typical parameters of learning have been observed, such as latency or path length. However, these parameters are sensitive to patterns of navigation and orientation that are not easily ...
-
(Academic Press, 2020)Consolidated memories can return to a labile state if they are reactivated by unpredictable reminders. To persist, active memories must be re-stabilized through a process known as reconsolidation. Although there is consistent ...
