The genetic basis of aggressive behaviour has been examined extensively, including analysis genes encoding neurotransmitters, signalling molecules and regulatory enzymes, as well their synthesis degradation. Dopamine beta-hydroxylase, an enzyme catalysing the conversion dopamine into norepinephrine in synaptic endings, significantly affects modulation emotional states behaviour. aim this study ...

This experiment assessed the yield and growth performance of the fodder tree planting in the community forest focusing on Artocarpus lakoocha, Bahunia purpurea. Major variables analyzing the yield and growth of the species such as dbh, height, green weight of the foliage was measured. After analyzing the data, Artocarpus lakoocha was found to be good yielding and growth performing species as co...

We assessed the effect that varying patterns of biomass allocation had on growth of ponderosa pine (Pinus ponderosa) growing in the desert climate of the Great Basin and the montane climate of the eastern Sierra Nevada. Prior work established that desert trees have lower leaf: sapwood area ratios than montane trees (0.104 and 0.201 M2/ cm2, respectively) and proportionally greater stem respirat...

The objective of this study was to select Pinus kesya progenies by the estimation of genetic parameters using the method of restricted maximum likelihood (Reml) and prediction of additive genetic values by the best linear unbiased prediction (Blup). The Pinus kesya progeny test was installed in randomized blocks, which consisted of 30 progenies and three replications. The twenty-year-old trees ...

Pharmacological studies in mammals suggest that norepinephrine (NE) plays an important role in promoting arousal. However, the role of endogenous NE is unclear, with contradicting reports concerning the sleep phenotypes of mice lacking NE due to mutation of dopamine β-hydroxylase (dbh). To investigate NE function in an alternative vertebrate model, we generated dbh mutant zebrafish. In contrast...

we investigated the relations among infection intensity of european mistletoe (viscum album l.) with host tree features in nour forest park, located in caspian forests in north of iran. the number of 30 circular plots with an area of 0.1 ha were sampled in all places have an aggregation of infested trees. parameters including dbh, height, distance to stand edge, distance to conspecific tree, ba...

Maintaining blood pressure during orthostatic challenges is primarily achieved by baroreceptor-mediated activation of the sympathetic nervous system, which can be divided into preganglionic and postganglionic parts. Despite their preganglionic autonomic failure, spinal cord-injured individuals demonstrate a preserved peripheral vasoconstriction during orthostatic challenges. Whether this also a...
