Mahisefid, Rutilus frisii kutum , is a cyprinid fish which is distributed from Turkmenistan to Azerbaijan along the Caspian Sea. It is one of the economically important fish in the region. As part of the Iranian Fisheries Company’s policy to improve the stocks of this species, every year, fingerling of Mahisefid are released into the southern basin of the Caspian Sea. The main objective of thi...

Conventional electrophysiologic measurements such as nerve conduction velocity, compound action potential, and neuropathic symptom scores have been used to assess the severity of diabetic neuropathy and have been the major efficacy end points following pharmacologic intervention trials. Unfortunately, these measurements are not particularly sensitive and their reproducibility is, at best, good....

When performing a regional-scale geomorphometric analysis, one might face a decision on whether to derive morphometric data from a low-resolution DEM or to calculate basic derivatives from a higher resolution dataset and average these data afterwards. This paper investigates differences between morphometric parameters (slope and aspect) derived from a resampled DEM and resampled morphometric da...

The jugular foramen (JF) varies in shape and size from side to side in the same cranium, and in different crania, racial groups and sexes. Side dominance is also said to be common. The foramen's irregular shape, its formation by two bones and the numerous nerves and venous channels that pass through it further compound its anatomy. A morphometric study of 20 (40 JF) adult male Nigerian dry skul...

OBJECTIVE To investigate the morphometric and topographic aspects of coronary ostia, correlating them with the aortic leaflets. METHODS Fifty-one hearts with the great vessels attached were analyzed in this study. The ascending aorta was transversally sectioned 1 cm above the commissures of the aortic leaflets. The right and left coronary ostia were analyzed, as were the distances from these ...

The axis (second cervical vertebra) is unique in possessing the dens or odontoid process and very specialized superior articular facets. The study was carried out to gather the metrical data of this atypical cervical vertebra. A hundred dried intact human axis vertebrae were measured using digital vernier caliper accurate up to 0.01 mm and a goniometer. Various linear and angular measurements o...

OBJECTIVE To evaluate the morphometry of the anterior thalamoperforating arteries (ATPA). METHODS A microanatomical study was performed in 79 specimens from 42 formalin-fixed adult cadaver brains. The origins of the ATPAs were divided into anterior, middle, and posterior segments according to the crowding pattern. The morphometry of the ATPAs, including the premammillary artery (PMA), were ex...
