Aerobic exercise and Orexin A: role of sympathetic activity and redox system.

Aerobic exercise and Orexin A: role of sympathetic activity and redox system. J Biol Regul Homeost Agents. 2019 Apr 10;33(2) Authors: Monda V, Villano I, Messina A, Valenzano A, Salerno M, Santo Signorelli S, Monda M, Russo V, Sessa F, Messina G Abstract Aerobic exercise is associated with the sympathetic activation evoking adaptive responses to sustain muscle engagement. Physical exercise can cause alterations in the cardiovascular activity and cellular stress may occur which could be marked by either heart rate (HR), or galvanic skin response (GSR). Moderate plasma levels of reactive oxygen species (ROS) are considered as health markers, absolving to important roles such as adaptive cellular responses to exercise. Orexin A, a hypothalamic peptide, causes a widespread stimulation of the sympathetic nervous system, playing a role in many physiological functions. PMID: 30968680 [PubMed - as supplied by publisher]

We describe a robust strategy for DM1 PGT-M that can be applied to virtually any at-risk couple. This strategy utilizes whole-genome amplification, followed by triplet-primed PCR (TP-PCR) detection of expanded DMPK alleles, in parallel with single-tube haplotype analysis of 12 closely linked and highly polymorphic microsatellite markers. Bidirectional TP-PCR and dodecaplex marker PCR assays were optimized and validated on whole-genome amplified single lymphoblasts isolated from DM1 reference cell lines, and tested on a simulated PGT-M case comprising a parent-offspring trio and three simulated embryos. Bidirectional DMPK T...

Even though genetic studies of individuals with neuromuscular diseases have uncovered the molecular background of many cardiac disorders such as cardiomyopathies and inherited arrhythmic syndromes, the genetic cause of a proportion of cardiomyopathies associated with neuromuscular phenotype still remains unknown. Here, we present a clinical case with a combination of cardiomyopathy and limb-girdle type muscular dystrophy where whole exome sequencing identified myoferlin (MYOF) – a member of the Ferlin protein family and close homolog of DYSF - as the most likely candidate gene. The disease-causative role of the ident...

ConclusionsStress score and sympathetic/parasympathetic ratio seem to be the best HRV predictors of internal load. Although there are no differences in HRV during recovery at the same time points in both conditions, the recovery is slower after exercise in HH than in HD.

In this study, we present a novel approach for inducing vasoconstriction by pulsed electrical treatment delivered via endovascular electrodes, which can be used in cases where external access to the vessel is limited. Methods: Using computer simulations, we optimized various geometries of endovascular electrodes to maximize the induced electric field on the arterial wall. Using the optimal configuration parameters, we investigated endovascular induced vasoconstriction in both the carotid and femoral sheep arteries. Results: Endovascular electrodes induced robust vasoconstriction in the carotid artery of sheep, showing grad...
