BACKGROUND Vagus nerve stimulation (VNS) is currently used to treat refractory epilepsy and is being investigated as a potential therapy for a range of conditions, including heart failure, tinnitus, obesity and Alzheimer's disease. However, the invasive nature and expense limits the use of VNS in patient populations and hinders the exploration of the mechanisms involved. OBJECTIVE We investig...

BACKGROUND The cardiac autonomic nervous system plays an essential role in epicardial ganglionated plexi (GP) regulation of atrial fibrillation onset and progression. To date, the activity of GP and the function of the cardiac autonomic nervous system are not well understood. The aim of this study was to determine alterations in epicardial GP cholinergic nerve, adrenergic nerve, and nerve growt...

Calcitonin gene-related peptide (CGRP) has inotropic and chronotropic effects in rat and guinea pig hearts. It also may mediate nonadrenergic noncholinergic regulation of canine cardiac electrophysiology. In this study, immunohistochemistry was used to determine the anatomic distribution of CGRP in mature dog heart and autonomic ganglia controlling cardiac function. The stellate ganglia had sca...

Hepatocytes have a great replicative capacity and are capable of repopulating the liver. Previous studies have suggested that the autonomic nervous system regulates liver regeneration and apoptosis. Moreover, the central nervous system modulates them through the autonomic nervous system. The lateral hypothalamus (LH) area and the ventromedial hypothalamus (VMH) nucleus have been studied for the...

background and aims: infraclavicular nerve block (icnb) is one of the most efficacious peripheral nerve blocks for upper extremity procedures, associated with several potential complications. recently, some authors have recommended ultrasound-guided peripheral nerve block for icnb. the current study is aimed to compare the outcomes of icnb utilizing combined ultrasound guidance and neurostimula...

UNLABELLED BACKGROUND The widespread of hallux valgus surgery in a day care setting enhanced the role of regional anaesthesia in the last few years. Sciatic nerve block at popliteal fossa has been shown to provide safe and effective analgesia. Our purpose was to compare the success rate and performance time of popliteal block during resident's training for regional anaesthesia by using nerve...

BACKGROUND This study aimed to compare the effects of femoral nerve block and adductor canal block on postoperative pain, quadriceps strength, and walking ability after primary total knee arthroplasty. METHODS Between November 2014 and February 2015, 60 patients underwent primary total knee arthroplasty. Thirty patients received femoral nerve block and the other 30 received adductor canal blo...

A new method of regional anaesthetic called Pericapsular Nerve Group block (PENG) blocks these nerves in order to target the hip's anterior capsule. PENG Block applications include medial thigh lesions, hip fractures, and vascular operations. Only ultrasonic guidance is used when performing Block, two methods—out-of-plane in-plane method—are with low-frequency probe. When employed a multimodal ...

OBJECTIVE Block of the sciatic nerve at the popliteal fossa can be performed using the ultrasound machine; it may be proximally or distally to the bifurcation of the sciatic nerve using lateral, medial, or posterior approaches. It is frequently used for surgeries below the knee specially the foot and ankle operations. PURPOSE This study compares one and two injections of the sciatic nerve in ...
