چکیده
established thatthere is a strong genetically inherited contributionto attention-deficit hyperactivitydisorder (ADHD) and the geneticmechanisms involved are being soughtwith considerable success.It is nowestablished thatcertain alleles of the genes coding for the dopamine D4 receptor and the dopamine transporteroccurmore frequently in childrenwith ADHD thanin healthycontrols, andwe are findingother DNAchanges associatedwith ADHD. Amajorchallenge for the field nowis to clarifyhowgenetic susceptibilityis translated into disorder byintegrating the fields of quantitative andmolecular genetics, neuropsychology and environmentalrisks.

A study on genetic aspects of seed dormancy
Changes in seed dormancy were selected during the domestication of crop plants from wild-plant species, because some features of dormancy that provide ecological advantages presented agronomic disadvantages within a farmed system. Seed dormancy varies widely among seed batches, even for seeds of the same genotype, indicating large environmental influences. For genetic studies, it is essential t...

متن کاملQuantitative studies for investigating variation and its effect on heterosis of rice
An important step in plant breeding programs is identification of parents that are geneticallydistant from each other, to find crossing combinations with better prospects of hybrid vigor. Thepotential of identifying genetically distant parents depends on genetic diversity of population. 58 linesof rice from diverse origins have been employed to study genetic variation in order to identify themo...
متن کاملQuantitative Structure-Activity Relationship Studies of 4-Imidazolyl- 1,4-dihydropyridines as Calcium Channel Blockers
Objective(s): The structure- activity relationship of a series of 36 molecules, showing L-type calcium channel blocking was studied using a QSAR (quantitative structure–activity relationship) method. Materials and Methods: Structures were optimized by the semi-empirical AM1 quantum-chemical method which was also used to find structure-calcium channel blocking activity trends. Several types of ...
متن کاملMarginal Analysis of A Population-Based Genetic Association Study of Quantitative Traits with Incomplete Longitudinal Data
A common study to investigate gene-environment interaction is designed to be longitudinal and population-based. Data arising from longitudinal association studies often contain missing responses. Naive analysis without taking missingness into account may produce invalid inference, especially when the missing data mechanism depends on the response process. To address this issue in the ana...
متن کاملQuantitative Structure Activity Relationship Analysis of Coumarins as Free Radical Scavengers by Genetic Function Algorithm
The antioxidant properties of coumarin derivatives using the 2,2ˈ -diphenyl-1- picrylhydrazyl (DPPH) radical scavenging assay were investigated by the application of Quantitative Structure Activity Relationship (QSAR) studies. The molecular structures were optimized and submitted for the generation of quantum chemical and molecular descriptors. Genetic Function Algorithm (GFA) was employed in m...
