An evaluation of the antireflux properties of sodium alginate by means of combined multichannel intraluminal impedance and pH-metry

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Gastroesophageal reflux evaluation in patients affected by chronic cough: Restech versus multichannel intraluminal impedance/pH metry.

OBJECTIVES/HYPOTHESIS Oropharyngeal (OP) pH monitoring has been developed to detect supra-esophageal gastric reflux (SEGR). The results obtained with OP pH-metry and multichannel intraluminal impedance/pH monitoring (MII/pH) were compared. STUDY DESIGN Diagnostic study. METHODS Ten patients (age 46.33 ± 9.86 years) presenting with chronic coughing underwent simultaneous OP and MII/pH record...

MULTICHANNEL INTRALUMINAL IMPEDANCE AND pH.

[Multichannel intraluminal impedance associated with pH-metry in the study of gastroesophageal reflux disease].

Multichannel intraluminal impedance and pH-metry for investigation of symptomatic gastroesophageal reflux disease.

BACKGROUND Combined multichannel intraluminal impedance and pH-metry (MII-pH) is a technique that enables monitoring of gastroesophageal reflux independent of its acidity. AIM To investigate the utility of MII-pH in the clinical investigation of patients with gastroesophageal reflux disease (GERD) symptoms. METHODS 32 consecutive patients underwent 24-hour ambulatory MII-pH. 16 patients wer...
