Background Meconium ileus (MI) is one type intestinal obstruction due to inspissated meconium at the level of the terminal ileum. The purpose of this study is to present the non-ionizing ultrasound-guided approach for the treatment of meconium ileus. Materials and Methods This study was performed, prospectively, at Dr. Sheikh and Akbar children's Hospitals, Mashhad University of Medical Science...

Soil-based wastewater treatment systems, or leachfields, rely on microbial processes for improving the quality of wastewater before it reaches the groundwater. These processes are affected by physicochemical system properties, such as O2 availability, and disturbances, such as the presence of antimicrobial compounds in wastewater. We examined the microbial community structure of leachfield meso...

BACKGROUND This subject-blind randomized clinical trial tested the efficacy of a new 5 percent sodium fluoride varnish (AllSolutions Fluoride Varnish, Dentsply Professional, York, Pa.) for treatment of cervical dentin hypersensitivity. The authors also compared the test varnish with a control fluoride varnish (Duraphat, Colgate Oral Pharmaceuticals, New York City). METHODS The study involved ...

AIM To evaluate the clinical treatment effects of a glycine powder air-polishing or ultrasonic device on peri-implant mucositis. MATERIALS AND METHODS Thirty-seven patients with one implant diagnosed with peri-implant mucositis (probing depth ≥4 mm (0.2N) and bleeding on probing (BOP) (primary outcome)) were randomly assigned to treatment with either glycine powder air-polishing (GPAP) or ult...

Pneumothorax in patients with progressive systemic sclerosis (PSS) often presents as a difficult-to-treat disease. Autologous blood-patch pleurodesis has previously been used for the treatment of pneumothorax. Blood outside its own environment is an irritant; therefore, chest physicians must watch closely for an allergic reaction. The injection is simple, painless, causes no side effects, is an...

The present study applies the model of American Meteorological Society-Environmental Protection Agency Regulatory Model (AERMOD) to investigate NO2 emissions from Besat thermal power plant, which is fuelled by natural gas to function. Results indicate that the simulated concentration of NO2 based on AERMOD, does not exceed NO2 concentration limit, set by the Iranian Ambient Air Quality Standard...

This in-vitro study evaluated the effectiveness of six different enamel treatment procedures for bonding a dental sealant. Sixty extracted human molar teeth were separated into the following enamel treatment groups (10 teeth each): group 1 (control)-etched with 37% phosphoric acid; group 2-air polished (air abraded) with 45 microns particles of sodium bicarbonate; group 3-air abraded with 50 mi...

We used a canine model of airway reactivity to examine the role of airway heat flux in the response to dry air challenge. Airflow-induced bronchospasm (AIB) was assessed by measuring collateral system resistance (Rcs) with a wedged bronchoscope technique in anaesthetized mechanically ventilated dogs. We manipulate post-challenge airway heat flux by exposing peripheral airways to cool dry air (2...
