Neuropeptide Y (NPY) is a neurotransmitter associated with feeding and obesity. We have constructed an NPY transgenic mouse model (OE-NPY(DBH) mouse), where targeted overexpression leads to increased levels of NPY in noradrenergic and adrenergic neurons. We previously showed that these mice become obese on a normal chow. Now we aimed to study the effect of a Western-type diet in OE-NPY(DBH) and...

Regression models to predict diameter at breast height (DBH) as a function of tree height and maximum crown radius were developed for Caribbean forests based on data collected by the U.S. Forest Service in the Commonwealth of Puerto Rico and Territory of the U.S. Virgin Islands. The model predicting DBH from tree height fit reasonably well (R2 = 0.7110), with strongest in subtropical moist and ...

Mice unable to synthesize norepinephrine (NE) and epinephrine due to targeted disruption of the dopamine beta-hydroxylase gene, Dbh, were used to critically test roles for NE in mediating acute behavioral changes elicited by different classes of antidepressants. To this end, we used the tail suspension test, one of the most widely used paradigms for assessing antidepressant activity and depress...

OBJECTIVE The incidence of heart attack and stroke undergo diurnal variation. Molecular clocks have been described in the heart and the vasculature; however it is largely unknown how the suprachiasmatic nucleus (SCN) entrains these peripheral oscillators. METHODS AND RESULTS Norepinephrine and epinephrine, added to aortic smooth muscle cells (ASMCs) in vitro, altered Per1, E4bp4, and dbp expr...

During differentiation of sympathetic neurons in chick embryos, tyrosine hydroxylase (TH) and dopamine b-hydroxylase (DBH) mRNAs become detectable during the same developmental period and are both induced by BMP 4. Later during sympathetic ganglion development, DBH is detectable in TH-positive and -negative cells. Moreover, BMPs reduce DBH mRNA in cultures of sympathetic neurons while leaving T...

بخشی از حجم بارش در مناطق مختلف کشور تحت تاثیر عواملی همچون پوشش گیاهی، کاربری اراضی، شیب زمین و شکل حوضه آبریز به رواناب سطحی تبدیل می شود. لذا برآورد حجم رواناب و بکارگیری روشهای جمع آوری آب های سطحی برای تامین آب، روز به روز اهمیت بیشتری پیدا می کند. استفاده از مدلهای هیدرولوژیکی این امکان را می دهد تا با شبیه سازی فرآیندهای هیدرولوژیکی، رواناب حاصل از بارش و ذوب برف در حوضه ها با کمترین هزی...

knowing and conducting studies on size characters of trees is essential for assessing the tree volumeand/or other statistical parameters and also forest management. the characteristics of 529 treesincluding diameter at breast height (dbh) and total height were measured in an even-aged fraxinusstand for two periods from 2005 to 2012 in chelir district, a part of experimental kheyrud forest.resul...

Abstract Key message We studied size distributions of decay-affected Norway spruce trees using cut-to-length harvester data. The data comprised tree-level decay and severity recordings from 101 final felling stands, which enabled to analyze relationships between all trees. Distribution matching technique was used transfer the distribution into diameter at breast height (DBH) Context Stem ( Pice...

An antiserum directed against tyrosine hydroxylase (TH), an enzyme involved in dopamine and norepinephrine synthesis, was used to visualize axons immunohistochemically in monkey neocortex. Labeled fibers were distributed throughout the entire neocortex, but they had striking patterns of regional and laminar specialization. For example, primary motor cortex contained the greatest density of TH-l...

PURPOSE To characterize neuropeptide distribution in the ciliary ganglion of rhesus monkeys (Macaca mulatta). METHODS Cryostat tissue sections of fixed rhesus monkey ciliary, pterygopalatine, superior cervical, and trigeminal ganglia were incubated with antisera to neuropeptide Y (NPY), calcitonin gene-related peptide (CGRP), substance P (SP), vasoactive intestinal peptide (VIP), tyrosine hyd...
