Ocean wave is one of the renewable energy resources that these days various devices are used to extract its energy. Oscillating Water Column (OWC) installed on the shore is one of the wave energy absorption systems which has received attention due to its simple structure. Investigation of the pneumatic power is of great importance in such systems as the conversion of wave energy to pneumatic en...

New pneumatic actuators developed in the author's laboratory will be presented with their applications to new mechatronics. Examples of them are a pneumatic rubber actuator for compliant robots, a micro pneumatic tube actuator assisting the colonscope insertion, a pneumatic stepping motor with high torque and resolution, a pneumatic drive bicycle, an intelligent pneumatic cylinder which has enc...

This article aims to provide some personal surgical tips increase the success rate of deep anterior lamellar keratoplasty (DALK), a very advantageous yet complex procedure for treating keratoconus. The most troublesome step is obtaining successful pneumatic dissection stromal tissue, allowing exposure cleavage plane. following may aid trainee surgeon in mastering this step, among others: perfor...

Despite several advances in the understanding of the pathophysiology of achalasia, treatment remains palliative as the neuronal defect of the disease seems to be irreversible. Currently, the most effective treatment options are graded endoscopic pneumatic dilation and laparoscopic Heller myotomy with partial fundoplication. Although both treatments seem to have similar efficacy in the short-ter...

Achalasia is an esophageal motility disorder that is commonly misdiagnosed initially as gastroesophageal reflux disease. Patients with achalasia often complain of dysphagia with solids and liquids but may focus on regurgitation as the primary symptom, leading to initial misdiagnosis. Diagnostic tests for achalasia include esophageal motility testing, esophagogastroduodenoscopy and barium swallo...

Achalasia is an uncommon primary motor disorder of the esophagus with an annual incidence of 0.8/100,000. Very few cases of coexistent Barrett’s esophagus (BE) and achalasia in patients without prior surgical myotomy or pneumatic dilation have been reported. We report the case of a 65-year-old female who was diagnosed with achalasia in June 2002. Endoscopy at that time revealed biopsy-confirmed...
