Adenylyl cyclase isoforms 5 and 6 in the cardiovascular system: complex regulation and divergent roles

Frontiers in Pharmacology
Adenylyl cyclases (ACs) are crucial effector enzymes that transduce divergent signals from upstream receptor pathways and are responsible for catalyzing the conversion of ATP to cAMP.

A joint computational respiratory neural network-biomechanical model for breathing and airway defensive behaviors

Frontiers in Physiology, 2012
Data-driven computational neural network models have been used to study mechanisms for generating the motor patterns for breathing and breathing related behaviors such as coughing. These models have commonly been evaluated in open loop conditions or with

Gapped $Z_2$ spin liquid in the breathing kagome Heisenberg antiferromagnet

, 2019
We investigate the spin-1/2 Heisenberg antiferromagnet on the kagome lattice with breathing anisotropy (i.e. with weak and strong triangular units), constructing an improved simplex Resonating Valence Bond (RVB) ansatz by successive applications (up to ...

Self-Regulation of Breathing as a Primary Treatment for Anxiety [PDF]

, 2015
Understanding the autonomic nervous system and homeostatic changes associated with emotions remains a major challenge for neuroscientists and a fundamental prerequisite to treat anxiety, stress, and emotional disorders.

Cord blood granulocyte levels are associated with severe bronchiolitis in the first year of life

Clinical & Translational Immunology
Objectives Bronchiolitis is a leading cause of infant hospitalisation in the first year of life, and it preferentially affects infants born to mothers with asthma.

Cognitive dysfunction and its association with inflammation in acute exacerbations of COPD: protocol for a prospective hospital-based cohort

BMJ Open
Introduction Chronic obstructive pulmonary disease (COPD) is characterised by progressive airflow limitation that is not fully reversible and is associated with an abnormal inflammatory response of lungs to noxious particles and gases.

Dead in the Night: Sleep-Wake and Time-Of-Day Influences on Sudden Unexpected Death in Epilepsy

Frontiers in Neurology, 2018
Sudden unexpected death in epilepsy (SUDEP) is the leading cause of epilepsy-related death in patients with refractory epilepsy. Convergent lines of evidence suggest that SUDEP occurs due to seizure induced perturbation of respiratory, cardiac, and ...

Reading, Writing, and Breathing [PDF]

, 2005
This report looks at the distribution of air toxics, respiratory hazard, and school children in the state of California. The report finds evidence of disproportionate exposure and a potential link between such exposure and school-level academic ...

The nonlinear damping of Bose-Einstein condensate oscillations at ultra-low temperatures

, 2002
We analyze the damping of the transverse breathing mode in an elongated trap at ultralow temperatures. The damping occurs due to the parametric resonance entailing the energy transfer to the longitudinal degrees of freedom. It is found that the nonlinear

Collective motions of a quantum gas confined in a harmonic trap [PDF]

, 2005
Single-component quantum gas confined in a harmonic potential, but otherwise isolated, is considered. From the invariance of the system of the gas under a displacement-type transformation, it is shown that the center of mass oscillates along a classical ...
