abstract   introduction: cervical cancer is one of the major causes of cancer and death among women aged 40 to 60 in developing countries. there is some difference, however, in the incidence of this cancer in iranian women compared to women living in western and south-east asian countries. we aimed at investigating the epidemiologic aspects and treatment results of cervical cancer among iranian...

neuropeptides, possessing specific and functional receptors on various cells of the immune system, have the potential to regulate immune responses; and the macrophages as important components of defense against various agents, are at their influence. in this study the effect of neuropeptides substance p (sp) and calcitonin gene-related peptide (cgrp) on il-1 beta production by herpes sim¬plex t...

an investigation was conducted on the effects of vermicompost as an organic matter and a substitute for fertilizers during year 2007 in ferdowsi university of mashhad (fum). vermicompost was applied at five levels (0, 10, 25, 50, 100%) and phosphorus at two levels with 3 replications for each treatment, as a factorial based on completely randomized design for super strain b tomato cultivar. the...

this paper is a density functional theory (dft) calculation of intramolecular proton transfer (ipt) in 6-hydroxypicolinic acid (6hpa, 6-hydroxypyridine-2-carboxylic acid) tautomeric forms. the transition state for the enol-to-keto transition is reported in the gas phase and in four different solvents. the planar and non-planar dimer forms of 6hpa keto and enol, respectively, were also studied i...

abstract   the perfect method for breast reconstruction would be safe, reliable, reproducible, applicable to all patients, and would have no donor site morbidity. the ideal reconstructed breast would provide symmetric, permanent, and natural results. there has been development and refinement of autogenous methods of breast reconstruction throughout the literature. the tram flap remains the most...

soil reduces the hazardous effects of compounds on the components of ecosystem because of self –purification property and the ability for their fixation. playing such a role in soils under redox conditions is performed by pedogenic fe-mn concentrations. in order to investigate cobalt, copper and lead accumulation in iron and manganese concentrations, at first the concentrations were precisely s...

background: hydroxymethylfurfural (hmf) is a common maillard reaction product directly formed from dehydration of sugars under acidic conditions during heating and storage in carbohydrate rich foods. the aim of the present study was to detect and quantify the amount of hmf in date syrup by hplc method. in addition, the amount of hmf in date syrup produced by traditional and industrial methods w...

the extensive use of pesticides in agriculture is compromising soil and water quality. one major concern is protecting water resources from contamination. the main objective of this research was measuring 2,4- d in a silty clay soil and simulating temporal transportation of this herbicide in soil using a leachp model, in a corn root zone field. 2,4- d was applied at 3.5 kg a.i./ha, followed by ...

an electroorganic reaction for the synthesis of 7-amino-2, 4-dioxo-5-phenyl-2,3,4,5-tetrahydro-1h-pyrano[2, 3-d] pyrimidine-6-carbonitrile and ethyl-7-amino-2, 4-dioxo-5-phenyl-2,3,4,5-tetrahydro-1h-pyrano[2, 3-d] pyrimidine-6-carboxylate derivatives are described, using an electrogenerated base of the anion of malonitrile or ethylcyanoacetate. this one-pot, three-component condensation of an a...

conclusions some il-10 promoter gene polymorphisms predisposed the infected hepatitis b virus cases to cirrhosis in our study population. patients and methods totally, 166 patients with chronic hepatitis b infection were enrolled. genotypes at different positions (i.e. -819, - 592, and - 1082) in the il-10 gene promoter were determined. results the c/a genotype at position -592, c/t genotype at...
