This study aimed to describe the brain base arteries of Myrmecophaga tridactyla using ten cadavers adults from this species, including five male and female specimens. The arterial vascular bed was perfused via thoracic aorta with a dyed natural latex solution, animals were fixed preserved 10% formaldehyde buffered solution. encephala removed, their vessels dissected. Basilar artery formation oc...

BACKGROUND AND PURPOSE Subclinical atherosclerotic plaques are common in patients with pontine infarctions (PIs) but without basilar artery (BA) stenosis. We hypothesized that BA plaque locations may differ by PI type and vertical location as well as vertebrobasilar artery geometry. METHODS Ninety-six patients with PI but without BA stenosis on magnetic resonance imaging (MRI) and magnetic re...

OBJECTIVES The purpose of this study was to determine whether sonography can identify the distal posterior interosseous nerve at the wrist. METHODS On the basis of previous anatomic descriptions, high-resolution musculoskeletal sonography was used in an attempt to identify the distal posterior interosseous nerve in the wrists of 20 unembalmed cadaveric specimens (11 male and 9 female; ages 54...

Radial artery is one of the smaller terminal branches of brachial artery which originates at the level of neck of radius. During routine dissection, a lot of variations in the arterial pattern of the upper limb were encountered which ignited our curiosity to review literature regarding the normal anatomy and variations of radial artery. There is marked difference in the arrangement of these art...

Previous studies from this laboratory have demonstrated an enhancement in both the contractile and signaling response to stimulation of either alpha-1 adrenoceptors or guanine nucleotide binding proteins (G proteins) in arteries from male Wistar rats with 12 to 14 weeks of streptozotocin-induced diabetes. The purpose of the present investigation was to determine whether changes in arterial alph...

Introduction: Brachial Artery (BA) begins as a continuation of axillary artery at the distal border teres major, it appears in cubital fossa, where ends level neck radius by dividing into radial and ulnar arteries. Common Interosseous (CIA) is largest branch Ulnar (UA) arises fossa. The terminal branches BA elbow are clinically important since they responsible for arterial supply to forearm han...

Doolen, Suzanne, Diana N. Krause, and Sue P. Duckles. Estradiol modulates vascular response to melatonin in rat caudal artery. Am. J. Physiol. 276 (Heart Circ. Physiol. 45): H1281–H1288, 1999.—The purpose of this study was to determine whether estrogen modulates the function of vascular melatonin receptors. We used the rat caudal artery and found that the contractile effects of melatonin were i...

BACKGROUND Injuries to the tibiofibular syndesmosis commonly cause prolonged ankle pain and disability. Syndesmotic injuries are associated with slower healing rates compared with rates for other ankle ligament injuries and typically result in longer time away from sports. To our knowledge, the vascular supply to the syndesmosis and its clinical implication have not previously been studied. The...

Although there have been attempts to make clinical-MRI correlation in patients with lateral medullary infarction (LMI), studies with a large number of patients are unavailable. In this study, clinical features, MRI findings and angiogram results of 130 acute, consecutive patients with pure LMI were studied and correlated. MRI-identified lesions were classified rostro-caudally as rostral, middle...
