although current guidelines place single leukotriene receptor antagonists use as a therapeutic option in mild persistent asthma, there is still uncertainty about its place. in this study efficiency of montelukast monotherapy in children with moderate persistent asthma was evaluated. children (age 6 to 16) with persistent moderate asthma were treated prospectively with budesonide combined with m...

objective: to determine the levels of polychlorinated biphenyls (pcbs) and polybrominateddiphenyl ethers (pbdes) as persistent organic pollutants (pops) in serum of primiparous women at the third trimester of pregnancy and identify the main determinants of pops levels such as socio-demographic, lifestyle, and diet in tehran. materials and methods: one- hundred eighty five serum samples from two...

cor triatriatum is an acyanotic congenital heart disease. we present a rare case of cor triatriatum sinistrum in a 6-month-old female infant who was presented with cyanosis and failure to thrive. the 2d transthoracic echocardiography and the doppler color flow imaging showed a proximal venous chamber communicating to the distal left atrium  through restrictive opening to the low-pressure, dista...

AIM To identify degenerative knee abnormalities using MRI and radiography 6 years after knee trauma, their relation with persistent knee symptoms and baseline prognostic factors. METHODS Adults (18-65 years) with incident traumatic knee symptoms visiting their general practitioner were followed up for 6 years and underwent baseline MRI and 6-year follow-up MRI and radiography. Logistic regres...

Artificial insemination (AI) involving the placing of frozen-thawed semen directly into the jenny uterine body is associated with very low pregnancy rates. This might be because of an exacerbation of the acute response of the endometrium to sperm, as seen in mares with persistent induced mating endometritis. Pregnancy rates can be increased in such mares, however, by including anti-inflammatory...

A single nondispersive excitation is observed by means of neutron backscattering, at E_{0}=26.3 microeV in the spin ice Ho2Ti2O7 but not in the isotopically enriched 162Dy2Ti2O7 analogue. The intensity of this excitation is rather small, less, similar0.2% of the elastic intensity. It is clearly observed below 80 K but resolution limited only below approximately 65 K. The application of a magnet...
