Effect of electroacupuncture on porcine cardiac excitability induced by left stellate ganglion stimulation

Augmentation of cardiac sympathetic tone has been shown to induce ventricular arrhythmias. Acupuncture has been clinically used to treat hypertension, angina pectoris, and atrial arrhythmias. However, the effects of acupuncture on ventricular electrophysiology and autonomic tone remain unknown. We hypothesized that acupuncture attenuates cardiac excitability and corrects the imbalance of autonomic tone during sympathetic hyperactivity. Fourteen Yorkshire pigs were randomized to electroacupuncture (EA, 2  Hz, 0.3–0.5 mA, 0.5 ms duration) or control (without EA) groups.

Publication date: 18 October 2018Source: Cell, Volume 175, Issue 3Author(s): Michael Tri H. DoAnimal photoreceptors divide into two fundamental classes, ciliary and rhabdomeric. Jiang and colleagues demonstrate that this boundary is disregarded by the intrinsically photosensitive retinal ganglion cells of mammals. These neurons draw from phototransduction mechanisms of both classes, enriching the signals that they produce to drive a diversity of visual functions.

In conclusion, a therapeutic dose of nifekalant had no effect on inotropic activity or cardiac compliance, whereas it showed negative lusitropic properties and QT/QTc prolongation in isoflurane-anesthetized monkeys. In addition, higher doses of nifekalant showed remarkable QT/QTc prolongation leading to arrhythmogenicity, which showed good accordance with clinical findings. Caution should be paid to negative lusitropic properties as well as arrhythmogenisity for the safe use of nifekalant. PMID: 30333366 [PubMed - as supplied by publisher]

Conclusions: NVI following KD is more common after lower energy-level mechanisms. Obesity is associated with NVI in lower energy-level mechanisms. Physicians should be vigilant in screening for NVI in the setting of KD even with seemingly benign mechanisms of injury, especially in patients with obesity. Level of Evidence: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Using traditional energetic points with an interaction of 5 elements and meridian theories with manual diagnosis of tender points has been proposed. This procedure can be an effective treatment in musculoskeletal disease but its development is short.ObjectivesTo evaluate the efficacy of energetic points of tendinomuscular meridian in the treatment of pain, quality of life and function of the knee.DesignRandomized controll...

Conclusion These findings suggest that the prevalence of PA may be high among patients with PC. An active examination is needed to detect PA, as its signs and symptoms may be mild in patients with PC associated with hypertension. PMID: 30333389 [PubMed - as supplied by publisher]

AbstractIntroductionLeft ventricular hypertrophy (LVH) can be successfully reduced by antihypertensive medication. Both hypertension and aerobic exercise can cause increases in left ventricular mass (LV-mass).AimTherefore, hypertensive athletes with LVH were studied to investigate the effect of antihypertensive medication on LV-mass reduction despite continuing their regular intensive exercise programs.Methods14 previously untreated hypertensive male athletes (A) with LVH and a prolonged history of endurance training where included in the study. 50 previously untreated inactive comparable hypertensives with LVH served as c...

AbstractThe underlying mechanism for clinical and biochemical manifestations of chronic heart failure (HF) may be due in part to neurohumoral adaptations, such as activation of the renin-angiotensin-aldosterone and sympathetic nervous systems in the periphery and the brain. Internet search and discussion with colleagues are the methods for this study. Since chronic HF is associated with autonomic imbalance with increased sympathetic nerve activity and a withdrawal of parasympathetic activity, it may be considered a brain disease. This phenomenon may be the result of an increased systemic and cerebral angiotensin II signali...

With regard to gastrointestinal functions, oxytocin acts centrally to regulate gastrointestinal motility. Visceral sensation is also known as one of key gastrointestinal functions which are controlled by the central nervous system (CNS). Little is, however, known about a role of central oxytocin in visceral sensation. The present study was therefore performed to clarify whether oxytocin in...

Endothelial cells respond to hemodynamic mechanical forces such as cellular mechanical stretching. We investigated the expression of glycosaminoglycans, proteoglycans and other extracellular matrix molecules in endothelial cells subjected to various mechanical stimuli.Main methodsEndothelial cells were subjected to mechanical stretch in a vacuum s...

In this study, we evaluated the effects of essential oil derived from Japanese cedar (Cryptomeria japonica) wood on the recovery state of female participants after they performed monotonous work. We determined the levels of salivary stress markers to describe the endocrinological responses. And we also used questionnaires to assess the perception of the odor of experimental rooms and psychological states. We found that olfactory stimulation with the volatile compounds of essential oil derived from Japanese cedar wood modulates mood states, and may transiently decrease sympathetic nervous activity. We suggest that olfactory...
