Aim: As to the assessment of occlusal status pertaining to primary canines and molars, the latter is less within reach as it is difficult to guide jaws towards a centric occlusion while maintaining a vintage point in both direct and indirect observation.  This study was originally intended to assess primary canine occlusion as a practical indicator in the evaluation of primary molar occlusion, ...

the runoff generation and soil erosion in the kechik watershed, golestan province, was assessed, using a designed and constructed portable rainfall simulator. treatments were applied on different land-uses, slopes and aspects as the most influential factors. results showed that land-use significantly affected runoff generation (13.35 l, 6.9 l, and 4.12 l, respectively for agriculture, forest an...

abstract background and aim: the aim of the present study was to evaluate the cephalometric changes in class ii division 1 mandibular deficient patients treated with farmand functional appliance.  methods and materials: twenty-seven subjects (17 girls and 10 boys) with the mean age of 11.1±1.4 years were involved in the present study. all the subjects were treated with farmand functional applia...

BACKGROUND AND AIM: Malocclusion has multifactorial etiology and the environmental factors play a major role in the occurrence of a malocclusion. Physical constraint faced by the disabled children may increase the chance of having malocclusion more than their normal counterparts. Thus, this study was done to evaluate the difference in the prevalence of Angle’s ...

background: human t cell lymphotropic virus type i (htlv-i)-associated myelopa-thy/tropical spastic paraparesis (ham/tsp) is an inflammatory disease which occurs in less than 2% of htlv-i -infected individuals. high proviral load, high htlv-i-specific cd8+ cytotoxic t lymphocyte frequency (ctl) and host genetic factors such as hla all appear to be associated with htlv-i infection. previous stud...

Objective(s): The population in Iran is a genetic admixture of the ancestral Aryan and other populations neighboring Iran. Different ethnic groups in Iran show wide regional distributions for many human leukocyte antigen (HLA) alleles. Therefore, it is necessary and sensible to study the differences in HLA allele distribution in different area. We studied the HLA class I and II allele frequenci...

Background: Human leukocyte antigens (HLAs) are found to be significant genetic factors concerning the susceptibility of an individual to certain diseases. Objective: To determine the association between variants of class I (A and B) and class II (DRB1) HLA alleles and chronic renal failure (CRF), compared with healthy controls, in Yemen. Methods: A case-control study in the Urology and Nephrol...
