the first epidemiologic survey of childhood allergic rhinitis in iran was carried out from may 1995 until april 1996.. a questionnaire was distributed among 4584, 11-15 year-old children of both sexes, to be completed under supervision of medical students. nasal smears were collected from the cases with allergic rhinitis (n = 445, 5.8%.), and from 340 healthy children for comparison. significan...

this paper presents the findings of experimental investigations into the effects of cutting speed, feed rate, depth of cut and approach angle on the machinability of titanium (grade-5) alloy. also the comparison for the two different cutting materials inserts polycrystalline diamond (pcd) and cubic boron nitride (cbn) with similar tool geometry for similar machining parameters is also carried o...

This article presents an experimental investigation and statistical analysis of the effects cutting conditions on machining performance AISI 1045 steel using a wiper-shaped insert. Experimental findings are used to compare obtained wiper inserts with those conventional round-nose as recently reported in literature. In addition, process conditions, namely speed, feed rate, depth cut, analyzed or...

The ever growing demand for reducing costs and decreasing the time to market in today’s plastics industry makes rapid tooling prototyping a highly researched area. 3D printed injection mold inserts make it possible produce prototype parts small series fast cost-effectively. mechanical strength therefore life expectancy of polymeric are low compared their traditional steel counterparts. In order...

BACKGROUND In June 2012, Canada implemented new pictorial warnings on cigarette packages, along with package inserts with messages to promote response efficacy (i.e., perceived quitting benefits) and self-efficacy (i.e., confidence to quit). This study assessed smokers' attention toward warnings and inserts and its relationship with efficacy beliefs, risk perceptions and cessation at follow-up....

Primary ciliary dyskinesia (PCD) is a rare disease with autosomal recessive inheritance, caused mostly by bi-allelic gene mutations that impair motile cilia structure and function. Currently, there are no causal treatments for PCD. In many models, translational readthrough of premature termination codons (PTC-readthrough) induced aminoglycosides has been proposed as an effective way restoring f...

OBJECTIVE To describe safety, tolerability, and effectiveness results through 5 years of follow-up of a Phase III trial with Essure inserts. DESIGN Multicenter, nonrandomized, single-arm international study (Canadian Task Force classification II-3). SETTING Thirteen clinical study centers in the United States, Europe, and Australia. PATIENTS A total of 518 previously fertile women seeking...

background and objectives: nasal polyposis is a diseases resulting from complex pathogenetic mechanisms. some studies showed that tgfβ1 had significant role in this pathogenesis. in this study, we investigated the roe of cytokines and mediators in polyp development. material and methods: in this case- control study, healthy nasal mucosal samples were obtained from 24 people undergoing septoplas...
