Background: We designed a prospective study to assess the role of Chlamydia in secondary infertility Materials and Methods: 40 women with secondary infertility and 30 term healthy pregnant women of similar age composition were studied for past and present chlamydia trachomatis infection. Women attending the outpatient department of Obstetrics and Gynaecology with complaint of secondary infertil...

background: this study aimed to assess dermis fat graft (dfg) as a choice to correct the tissue deficit in the free border of the upper lip in cleft lip repair surgery. materials and methods: thirty?five individuals who referred to alzahra hospital at 2013–2014,with lip deformity following the primary repair surgery of cleft lip underwent surgery by dfg technique. outcomes were assessed 4 month...

chemical oxidation is one of the most suitable treatment methods for reducing organic pollutants and the number of pathogens remaining in secondary effluents. ozone is the most powerful oxidizing agent commonly used because of it's many advantages over chlorination. in this study the efficiency of ozonation in advanced wastewater treatment of sahebgharanieh plant has been determined. ozone gene...

the coexistence of two malignancies is rarely seen. a little association between hematologic malignancies especially multiple myeloma and renal cell carcinoma has been reported in the recent past. several case series revealed a bidirectional association between these two malignancies which may be due to the common risk factors, similar cytokine growth requirements and clinical presentation. her...

in this study, the effect of the secondary structure of the protein on the acid strength of three structures of random (r), alpha helix (α) and beta sheet (b) were investigated theoretically. these structures are related to the cationic amino acids of histidine and lysine in the polypeptide chain of eight-glycine residue. computational methods at the hf, b3lyp, x3lyp and m05-2x levels in the ga...

in many active noise control (anc) applications, an online secondary pathmodelling method that uses a white noise as a training signal is required. this paperproposes a new feedback anc system. here we modified both the fxlms and thevss-lms algorithms to raised noise attenuation and modelling accuracy for theoverall system. the proposed algorithm stops injection of the white noise at theoptimum...

the immiscible displacement of oil by water through a porous and permeable reservoir rock can be described by the use of a fractional flow curves (fw versus sw). water flooding project parameters can be obtained from the fractional flow curve. however, developing a representative fractional flow curve for a specific reservoir can be quite challenging when fluid and special core analysis data is...

two field and laboratory experiments were conducted to investigate the effects of superabsorbent polymer (sap) and irrigation management on seed and essential oil yields of cumin, as well as the impact of water quality on water holding capacity of sap. salinity had a negative effect on the amount of water absorbed by sap (335 and 59 g h2o per g sap, for distilled water and solution of 0.5% nacl...

purpose: to compare the rate of fibrovascular ingrowth between primary and secondary orbital implants at varying time intervals after implantation. methods: we prospectively compared the rate of fibrovascular ingrowth between primary and secondary implants by mri and scinitigraphy in patients who underwent orbital implant surgery, 6 months after the operation. results: overall 103 patients unde...
