Background: Twin, family, and linkage studies have indicated that attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorders (ASDs) share a portion of their heritable etiology. This suggests that individuals with ADHD may manifest different forms of ASDs that may range from fully developed syndromic forms of the disorder to milder manifestations of ASD symptomatology, which w...

grapevine is among some of the most important horticultural crops in the world and as well in iran. since last century attempts have been made throughout the world to improve grapes. research in grape breeding for the purpose of improving table grape as well as raisin traits has started since 1996 in iran with crossing some selected seedless (askary, yaghoti, bidane sefid (sultana) and bidane g...

Data from 183 animals raised in 61 flocks were collected to investigate the morphological characteristics of the Northern Morocco goat. Nine zoometric measures and seven combined indices were obtained. Three zones were defined  based on geo-climatic characteristics and environmental influences: Mediterranean, Atlantic and Dual. The morphological variables showed the absence of sexual dimorphism...

background and objectives: over the last two decades, a large number of researches have been conducted regarding the importance of nitrogen in sugar beet. this indicate that there were needs to investigate more on nitrogen management to achive higher production and quality because less nitrogen application result in reducing yield and high nitrogen application would increase production costs an...

the main objective of this study was to understand of genetic association between quantitative and qualitative traits and also to quantify effects of selection for one trait on others in safflower. the study took place in the experimental field of the faculty of agriculture, isfahan university of technology, isfahan, iran, in the 2001 and 2002. to find the best variable for selection to improve...

in order to study the possibility of control of heterodera schachtii  in sugarbeet fields through integration of rotation with non- host crops and resistant catch crops and their effects on quantitative and qualitative traits of sugarbeet, this study was started from 2002 for three years in esfahan province. the experiments were carried out in a randomized complete block design with eight treat...

The effect of virus-host interactions on subsequent generations is poorly understood. The evaluation of the effects of viral infection on inheritance of quantitative traits in the progeny of infected plants and elucidation of a possible relationship between chiasma frequency in the infected plants and variability of traits in the progeny were investigated. The current study involved genotypes o...

Leaf venation is diverse across plant species and has practical applications from paleobotany to modern agriculture. However, the impact of vein traits on plant performance has not yet been tested in a model system such as Arabidopsis thaliana. Previous studies analysed cotyledons of A. thaliana vein mutants and identified visible differences in their vein systems from the wild type (WT). We me...

Substance abuse is related to re-offending, and substance abuse treatment may be effective in reducing criminal recidivism. Psychopathy, however, another factor that strongly correlates with re-offending, may be negatively associated with treatment utilization. This qualitative study explored perceptions of substance abuse treatment among offenders with mental health problems, problematic subst...
