Entropy is a powerful tool for quantification of the brain function and its information
processing capacity. This is evident in its broad domain of applications that range from …

The European population is ageing, and there is a need for health solutions that keep older
adults independent longer. With increasing access to mobile technology, such as …

The observation that antagonists of the N-methyl-D-aspartate receptor (NMDAR), such as
phencyclidine (PCP) and ketamine, transiently induce symptoms of acute schizophrenia had …

Abstract Background Approximate entropy (ApEn) and sample entropy (SampEn) have been
previously used to quantify the regularity in centre of pressure (COP) time-series in different …

The mammalian skin is a heterogeneous organ/tissue covering our body, showing regional
variations and endowed with neuroendocrine activities. The latter is represented by its ability …

Steroid hormones are an important class of regulatory molecules that are synthesized in
steroidogenic cells of the adrenal, ovary, testis, placenta, brain, and skin, and influence a …

Advanced age is associated with an increased risk of vascular morbidity, attributable in part
to impairments in new blood vessel formation. Mesenchymal stem cells (MSCs) have …

G protein coupled receptors (GPCRs) were first characterized as signal transducers that
elicit downstream effects through modulation of guanine (G) nucleotide-binding proteins …

There have long been suggestions that aging is tightly linked to the complex dynamics of the
physiological systems that maintain homeostasis, and in particular to dysregulation of …

Standing postural control is complex, meaning that it is dependent upon numerous inputs
interacting across multiple temporal-spatial scales. Diminished physiologic complexity of …
