OBJECTIVE To analyze the relationship between myocardial bridges and the anterior interventricular branch (anterior descending) of the left coronary artery. METHODS The study was carried out with postmortem material, and methods of dissection and observation were used. We assessed the perimeter of the anterior interventricular branch of the left coronary artery using a pachymeter, calculated ...

Crotches were cut out of red maple (Acer rubrum), callery pear (Pyrus calleryana), and sawtooth oak (Quercus acutissima) trees (2.5”-7” d.b.h.) and then pulled apart in an engineering testing machine to identify physical parameters correlated with crotch strength. Parameters measured included the diameter of the branch and of the trunk above and below the crotch, angle of the branch and branch ...

Local variation in the abundance and richness of vascular epiphytes is often attributed to environmental characteristics such as substrate and microclimate. Less is known, however, about the impacts of tree and branch turnover on epiphyte communities. To address this issue, we surveyed branches and epiphytes found on the forest floor in 96 transects in two forests (Atlantic rainforest in Brazil...

Stem/branch maintenance respiration for a stand of Japanese red pine (Pinus densiflora) during the dormant season was examined using an open flow system. The stem/branch respiration rates per unit of volume were closely related to the thickness of the stems and branches, e.g. it decreased with increasing diameter (p<0.0001). When the respiration rates on the various positions were regressed aga...

KOIKE, K., OHNUKI, T., OHKUDA, K., NITTA, S. and NAKADA, T. Branching Architecture of Canine Pulmonary Arteries. A Quantitative Cast Study. Tohoku J. exp. Med., 1986, 149 (3), 293-305 The purpose of this investigation is to analyze the branching pattern of pulmonary artery. The excised right lower lobes of six mongrel dogs were fixed by perfusion with 1.2% glutaraldehyde solution. Pressure of t...

Data collected from four distinct canopy positions from each of 39 Abies balsamea (L.) Miller trees were used to construct models to describe the cumulative leaf area distribution within the crown and to predict the needle mass of individual branches, the average branch angle, branch diameter, branch length, and crown radius per whorl, and the average number of living branches per whorl. We tes...

pistachio is the most important nut that is produced in iran. little research has been done to examine the effect of ucb1-hybride rootstock plants as tissue culture for pistachios (2011 in toba company).this study aims to evaluate three pistachio varieties on ucb1 hybrid rootstock.  the experiment was conducted as a randomized complete block design with three treatment groups (including ohadi, ...

background: small side branches, albeit less important than their larger counterparts, have not yet received due attention in the literature. nor has there ever been a comparison between drug-eluting stents and bare metal stents apropos side branch occlusion . the aim of this study was to compare the patency of small (≥0.5 and ≤1.5 mm in diameter) side branches with respect to bare metal vs. dr...

AIM The masseter muscle is often exploited by craniofacial surgeons in transposition operations to correct facial palsy, benign masseteric hypertrophy; or neurectomy-induced atrophy of the muscle. A clear understanding of the course of the premasseteric branch of the facial artery and its relations with adjacent structures is essential in maneuvering the masseter muscle safely. In the present s...

Knot-related defects are the major cause of timber quality degradation, and diminishing this kind of defects is an important issue in forest management. For the purpose of clear-wood production, knot attributes and branch occlusion of Betula alnoides under natural pruning were investigated in a 14-year-old experimental plantation with five planting densities ranging from 500 to 3333 stems per h...
