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.

Authors: Sunohara M, Kriz W, Kränzlin B, Kretzler M, Gretz N, Endlich K, Endlich N Abstract Elevated mechanical stress in glomerular hypertension is thought to damage podocytes, the loss of which leads to development of glomerulosclerosis. Applying cDNA array analysis to mechanically stressed podocytes, we have recently identified TSG101 as a stretch-induced candidate gene among others. TSG101, which is part of the ESCRT-I complex, is involved in multivesicular body (MVB) formation. Here we demonstrate that TSG101 mRNA is strongly upregulated in conditionally immortalized mouse podocytes by cyclic mechanical s...

Background Rapid syphilis tests (RST) may shorten time to syphilis diagnosis and treatment while enhancing access to testing in outreach settings. There are limited data on the performance of RST in outreach settings in the US. Methods We offered RST (Syphilis Health Check) at 6 outreach sites to men who reported having sex with men and no prior history of syphilis. Clients accepting RST were also tested with laboratory-based rapid plasma reagin (RPR) and reflex Treponema pallidum particle agglutination (TPPA) assay when RPR or RST were positive. Clients with positive RST were immediately referred to a sexually transm...

AbstractThe longer survival of patients with Duchenne muscular dystrophy due to advances in clinical care has increased the incidence of Duchenne muscular dystrophy-associated cardiomyopathy, a nearly consistent feature in the third decade of life. A 26-year-old patient with Duchenne muscular dystrophy experienced severe acute heart failure triggered by pneumonia. Levosimendan was effective in improving heart function.

AbstractObesity is a severe worldwide epidemic. Obesity comorbidities, such as type 2 diabetes mellitus, hypertension, and atherosclerosis, are costly for patients and governments. The treatment of obesity involves several facets, including lifestyle changes, bariatric surgery, and pharmacotherapy. As changes in lifestyle require considerable patient commitment that is sometimes unachievable, and surgery is expensive and invasive, pharmacotherapy is the primary option for most patients. This review describes the pharmacotherapy currently available in the USA, Europe, and Brazil, focusing on its limitations. We then analyze...

In this study, electrophysiological markers of attention, posterior contralateral N2 (N2pc), and working memory, contralateral delay activity (CDA), were used to explore the relationship between these two cognitive abilities in patients with ADHD. EEG data were collected from adults with ADHD and age-, sex-, and IQ-matched normal controls while performing a classical visuospatial working memory task that consisted of low-load and high-load memory conditions. In different memory load conditions, the memory array elicited a smaller N2pc (220–260 ms) and a smaller CDA (400–800 ms) in adults with ADHD than in n...

ABSTRACT Maurice Ravel is one of the most important French musicians. In the last years of his life, Ravel was victim of a dementia of uncertain etiology that caused aphasia, apraxia, agraphia and amusia. The artistic brain of the author of eternal musical compositions was progressively silenced due to his neurodegenerative disease. On the 90th anniversary of Bol éro, this historical note revisits Ravel's case and discusses the relationship of his dementia to his artistic production. It illustrates the intimacy that can exist between art, music, creativity, and neurology.RESUMO Maurice Ravel é um dos mú...
