our aim was to evaluate the short and long term efficacy of botulinum toxin therapy in iranian patients with achalasia. in a randomized, double blind trial, 20 patients with achalasia, referring to imam khomeini hospital, received either 80 units of botulinum toxin (bt) or placebo (pl) from 1995 to 1998. two weeks later, the response to treatment was assessed on the basis of changes in the symp...

Background and Aim: Water sorption is one of the most important properties that affects the quality of a prosthesis, and subsequently, the quality of treatment, and pa-tient’s quality of life. The aim of this study was to determine and compare the water sorption of two types of poly methyl methacrylate (PMMA) using the injection-molding systems with a traditional acrylic resin base material. M...

background. this clinical trial evaluated the effect of simvastatin on space re-opening after orthodontic space closure and its effect on the gingival index (gi) and clinical attachment loss (cal). methods. 16 females, 25‒40 years old, with spaces between anterior mandibular teeth due to chronic periodontitis were participated in this study. the patients were randomly divided into control and e...

The subject of optimal control is researched during the insertion of the space vehicle into the orbit of Mars artificial satellite with the preliminary aerodynamic braking in the atmosphere. The space vehicle control methodology of roll angle and angle of attack is elaborated. Variational problems are solved for minimization of necessary power inputs and maximization of space vehicle re-entry c...

We studied the clinical effect of oxygen-ozone treatment of lumber disc herniation. Oxygen-ozone was administered by percutaneous injection (35-yong/ml), 6-15 ml into the intralumbar disc, and a few patients needed re-injection 48 hours later. We treated 323 patients with 433 discs with a total effective rate of 77.7%. Treatment of lumber disc herniation by oxygen-ozone was simple, safe and eff...

Botulinum toxin Type A in Facial Aesthetics”. Subjects were blinded as to which method was used. All patients received 20 units of BT in the glabellar region (Botox, Allergan, Irvine, CA). Follow-up photographs and DISC analysis were completed weekly for the first month, then monthly up to six months post-injection. The Facial Lines Outcome 11-item survey (FLO-11) survey was also administered a...

Re-injection of produced geothermal water for pressure support is a common practice in geothermal field management. The location selection of the reinjection well and the rate of injection is a challenging subject for geothermal reservoir engineers. The goal of optimization for this type of problem is usually to find one or more combinations of geothermal re-injection well locations that will m...

UNLABELLED Radioimmunotherapy (RIT) can be performed with various radionuclides. We tested the stability, biodistribution, and therapeutic efficacy of various radioimmunoconjugates ((131)I, (88/90)Y, (177)Lu, and (186)Re) of chimeric antirenal cell cancer monoclonal antibody G250 (mAb cG250) in nude mice with subcutaneous renal cell cancer (RCC) tumors. METHODS The (88/90)Y and (177)Lu labeli...

BACKGROUND Unsafe injection practice can transmit various blood borne infections. The aim of this study was to assess the knowledge and practice of injection safety among injection providers, to obtain information about disposal of injectable devices, and to compare the knowledge and practices of urban and rural injection providers. METHODS The study was conducted with injection providers wor...

Method and materials C57BL/6 mice were engrafted with syngeneic GD2expressing B78 melanoma. Macroscopic tumors (~ 200 mm3) were treated with sham or single fraction 12 Gy RT. Mice then received 5 daily intra-tumor injections of human IgG, hu14.18 mAb, or hu14.18-IL2 IC. NK or T cell depletion was achieved by intraperitoneal injection of a depleting mAb (NK1.1 or CD4/CD8 mAbs). After 90 days mic...
