We study superconducting and non-superconducting nanorings and look for non-classical features of magnetic flux passing through nanorings. We show that the magnetic flux can exhibit purely quantum properties in some peculiar states with quadrature squeezing. We identify a subset of Gazeau-Klauder states in which the magnetic flux can be squeezed ...

Among double perovskites, the interpretation of the magnetic, thermal and transport properties of Sr(2)YRuO(6) remains a challenge. Characterization using different techniques reveals a variety of features that are not understood, described as anomalous, and yields contradictory values for several relevant parameters. We solved this situation through detailed susceptibility, specific heat, ...

Pituitary adenylate cyclase-activating polypeptide (PACAP) is a neuropeptide expressed widely in nervous tissues. PACAP-knockout ((-/-) ) mice display a sudden infant death syndrome (SIDS)-like phenotype, although the underlying physiological mechanism to explain this remains unclear. Here, we report on the presence of abnormal respiratory activity in PACAP(-/-) mice under hypoxic ...

ABSTRACT Endothelial dysfunction characterized by decreased nitric oxide (NO) bioavailability is the first stage of coronary artery disease. It is known that one of the factors associated with an increased risk of coronary artery disease is a high plasma level of uric acid. However, causative associations between hyperuricaemia and cardiovascular ...

Specialized primary afferents, although they terminate in different laminae within the dorsal horn (DH), are known to interact through local circuit excitatory and inhibitory neurons. That a loss of segmental inhibition probably contributes to persistent pain hypersensitivity during chronic pain raises the question as to how disinhibition-induced changes in cross-modal ...

Cyclophilins catalyze the reversible peptidyl-prolyl isomerization of their substrates and are present across all kingdoms of life from humans to bacteria. Although numerous biological roles have now been discovered for cyclophilins, their function was initially ascribed to their chaperone-like activity in protein folding where they catalyze the often rate-limiting step ...
