Annual measurements on growth traits from a total of 275 parents and 690 full-sib families from 23 diallel tests of loblolly pine (Pinus taeda L.) in the Northern, Coastal and Piedmont test regions of the southeastern U.S. were used to reveal the time trend of genetic parameters through age 8. Variance components were estimated from mixed model analyses on growth traits (height, DBH and volume)...

OBJECTIVE To study the association of Attention Deficit Hyperactivity Disorder (ADHD) and polymorphism in the dopamine beta hydroxylase (DBH) gene in Indian ADHD cases. SUBJECTS Forty one ADHD cases were diagnosed as per the DSM-IV-TR criteria and evaluated by Conners Parents and Teachers Rating Scale and Wechslers Intelligence Scale for Children. METHODS Genomic DNA was amplified for exon ...

Objective: Interaction between genetic and environmental factors is considered as major factors in Schizophrenia (SCZ). It has been shown that dopaminergic and noradrenergic neurotransmission dysfunction play an essential role in the SCZ pathogenesis. This study aimed to find the impact of functional 19-bp insertion/deletion (ins/del) polymorphism in dopamine beta-hydroxylase (DBH) gene on SCZ ...

Background—Elevated circulating norepinephrine (NE) has been implicated in causing the profound b-adrenergic receptor (bAR) downregulation and receptor uncoupling that are characteristic of end-stage human dilated cardiomyopathy, a process mediated in part by increased levels of b-adrenergic receptor kinase (bARK1). To explore whether chronic sustained NE stimulation is a primary stimulus that ...

We present a novel approach to generating regional scale aboveground biomass estimates for tree species of the Lake Tahoe Basin using hyperspatial (<1 m ground resolution) remote sensing imagery. Tree crown shadows were identified and delineated as individual polygons. The area of shadowed vegetation for each tree was related to two tree structural parameters, diameter-at-breast height (DBH) an...

BACKGROUND Increased dopaminergic activity may play a primary role in psychotic depression. Dopamine beta-hydroxylase (DbetaH) catalyses the key step in biosynthesis of the neurotransmitter noradrenaline from dopamine, and low DbetaH activity is a possible risk factor for developing psychotic depression. An exon 2 polymorphism (DBH*444 g/a) of the DbetaH gene (DBH) is significantly associated w...

Some epidemiological studies have investigated the relationship between genetic polymorphisms of DRD2, COMT, DBH, and MAO-A and migraine susceptibility, but the results are still inconsistent. Thus, our aim was to further assess the association through a meta-analysis.We examined 5 single nucleotide polymorphisms (SNPs) in 4 genes, including DRD2 rs1799732 and rs6275, DBH rs7239728, MAI-A-VNTR,...

The Guazuma crinita Mart. is a dominant species of great economic importance for the inhabitants Peruvian Amazon, standing out its rapid growth and being harvested at an early age. Understanding vertical challenge that researchers have continued to study using different hypsometric modeling techniques. Currently, machine learning techniques, especially artificial neural networks, revolutionized...

DBH is a candidate gene in Parkinson’s disease (PD) and contains a putative functional polymorphism (-1021C3T) that has been reported to modify PD susceptibility. We examined 1021C3T in a sample of 1,244 PD patients and 1,186 unrelated control subjects. There was no significant difference in allele (p 0.14) or genotype (p 0.26) frequencies between the two groups. A similar result was obtained a...

CCK octapeptide (CCK-8) is released by the gut in response to a meal and acts via CCK(A) receptors on vagal afferents to induce satiety. However, the central neural pathways by which peripheral CCK-8 affects feeding are poorly understood. In the present study, we tested the hypothesis that norepinephrine (NE) is necessary for satiety induced by peripheral CCK-8 by using mice lacking dopamine be...
