Endoscopic sensing of alveolar pH.

Difficulties in the diagnosis and management of alveolar hydatid disease: A case series

Background: Alveolar echinococcosis (AE) is a chronic, rare and sometimes lethal parasitic infection in humans, caused by the larval stage of the fox tapeworm Echinococcus multilocularis. This study aimed to investigate the clinical aspects and treatment outcomes of patients with alveolar hydatid disease. Methods: The medical records of patients with alveolar echinococcosis admitted between ...

Evaluation of Gastroesophageal Reflux Disease Using the Bravo Capsule pH System.

Gastroesophageal reflux disease (GERD) is a disease predominantly seen in the West but there is a rising trend in Asia. Ambulatory 24-hour catheter-based pH monitoring has been the de facto gold standard test for GERD that correlates symptoms with acid reflux episodes. However, drawbacks such as patients' discomfort, and catheter displacement render the test as cumbersome and error-prone. The B...

بررسی اندوسکوپیک آناتومی حفره پتریگوپالاتین در اجساد بالغ ایرانی

  Background : Our aim in this study was to recognize the endoscopic anatomy of the Pterygopalatine fossa (PPF) and the anatomic variations of the related neurovascular structures, to define the endoscopic endonasal approach to this region.   Methods: In a case series study 17 fresh adult cadavers were studied by endoscopic endonasal approach. To reach the pterygopalatine fossa endonasally, we ...

Hepatobiliary alveolar echinococcosis infiltration of the hepatic hilum diagnosed by endoscopic ultrasonography-guided fine-needle aspiration.

Voltage-gated proton channels help regulate pHi in rat alveolar epithelium.

Voltage-gated proton channels are expressed highly in rat alveolar epithelial cells. Here we investigated whether these channels contribute to pH regulation. The intracellular pH (pH(i)) was monitored using BCECF in cultured alveolar epithelial cell monolayers and found to be 7.13 in nominally HCO(3)(-)-free solutions [at external pH (pH(o)) 7.4]. Cells were acid-loaded by the NH(4)(+) prepulse...
