objective(s) the objective of this study was to document and explain bilateral differences in the q angle. materials and methods two hundred limbs of healthy adult indian volunteers were studied. the q angle was measured using a goniometric method with the subjects supine, quadriceps relaxed and lower limbs in neutral rotation. the relative lateral placement of the tibial tuberosity with respec...

background: antigen b (agb) is frequently used for immuno-diagnosis of hu-man cystic echinococcosis (ce). echinococcus granulosus agbs show a high degree of genetic variability in different hosts or in different ce endemic areas. the present study aimed to evaluate the genetic polymorphisms of encoding antigen b2 gene (agb2) among different iranian isolates of e. granulosus. methods: a total of...

little information is available regarding genetic variation in wild wheat relatives from iran. in this study, genetic diversity of 36 populations of wild einkorn wheat, triticum boeoticum, was studied using amplified fragment length polymorphism (aflp) primer combinations. seventeen aflp primer combinations led to amplify 979 scorable fragments ranging from 50 to 500 bp and of these, 429 (44%) ...

the pragmalinguistic and sociopragmatic aspects of language use vary across different situations, languages, and cultures. the separation of these two facets of language use can help to map out the socio-cultural norms and conventions as well as the linguistic forms and strategies that underlie the pragmatic performance of different language speakers in a variety of target language use situatio...

nitrate concentration of the soil, at the start of growing season, is high due to minerali-zation of soil organic n during the fall and the addition of n fertilizers. it may be useful to exploit this n form as much as possible. therefore, the nitrate uptake, assimilation and dry matter production of several wheat cultivars were examined in a series of experiments using a hydroponic culture syst...

secale montanum is one of the important perennial grasses growingnaturally in arid to semiarid pastures and rangelands, with a typical mediterraneanclimate, in northern and western iran at altitudes of 800-2900 m. in this paper, seedstorage protein profiles of nine wild populations of s. montanum from differentregions of iran and their phenotypically superior progenies as well as a multi-origin...

The accumulation of genome-wide information on single nucleotide polymorphisms in humans provides an unprecedented opportunity to detect the evolutionary forces responsible for heterogeneity of the level of genetic variability across loci. Previous studies have shown that history of recombination events has produced long haplotype blocks in the human genome, which contribute to this heterogenei...

Terrestrial vegetation exerts an important influence on climate variability via the exchange of mass, energy, and momentum between the land surface and the atmosphere. This dissertation uses statistical techniques and stochastic models to investigate largescale vegetation/climate interactions in remotely-sensed vegetation datasets and observational climate records. Vegetation feedbacks on clima...

abstract the temperature of water entering the soil or variation in soil temperature has a direct impact on soil hydraulic conductivity via the effect on water viscosity. in this research, the time variability of soil saturated hydraulic conductivity (ks) was studied. the relation between soil temperature and fluid viscosity with hydraulic conductivity were also studied. the necessary experimen...

background and objective: obstructive sleep apnea syndrome (osas) is a prevalent disease in adults. limited evidence regarding the effect of severity of sleep apnea and depression on heart rate variability (hrv) indices exists. hence, we decided to focus on the association between hrv and severity of osas based on depression score. materials and methods: a total of 193 patients with confirmed o...
