Knowledge of incidence of morphological variations in the course and branching of the carotid arteries is important for radiological interpretation and surgical correction when they are symptomatic. Internal carotid artery (ICA) is known to show elongation in its extra cranial course. Previous studies have demonstrated the incidence and clinical symptoms of this morphological entity. However, t...

Morphological description of sand,flies has remained a neglected area. The different organs used in taxonomy have not yet been described adequatelAy with the scanning electron microscopy (SEM). We have examined the external genital structures offemales of three Old World phlebotomine sand,flies under SEMand recorded the morphological variations of the organs. We have,found the,female external g...

This paper presents morphological operators with nonxed shape kernels, or amoebas, which take into account the image contour variations to adapt their shape. Experiments on grayscale and color images demonstrate that these novel lters outperform classical morphological operations with a xed, space-invariant structuring element for noise reduction applications. Tests on synthetic 3D images are t...

Although morphological transitions (such as hyphae and pseudohyphae formation) are a common feature among fungi, the encapsulated pathogenic yeast Cryptococcus neoformans is found during infection as blastoconidia. However, this fungus exhibits striking variations in cellular structure and size, which have important consequences during infection. This review will summarize the main aspects rela...

Basic studies were carried out to apply frozen allogeneic nerve grafts in dogs after wide-ranging defects of the brachial plexus due to surgical resection of tumor. In this study, morphological variations in branching patterns of the brachial plexus were examined in ten beagle dogs, to evaluate whether the brachial plexus might represent a useful source of allogeneic nerve grafts. Spatial relat...

All fish species in the Anabantoidei suborder are aquatic air-breathing fish. These species have an accessory air-breathing organ, called the labyrinth organ, in the branchial cavity and can engulf air at the surface of the water to assist in gas exchange. It is therefore necessary to examine the extent of gill modification among anabantoid fish species and the potential trade-offs in their fun...

The paper describes the male of Cyrtopsis t-sigillata Liu, Zhou & Bi, 2010 for the first time, and discusses individual variations in the species. It provides the photos of important morphological features, and offers a distribution map about the genus Cyrtopsis Bey-Bienko, 1962. The examined material is deposited in the Museum of Hebei University. Morphological images were acquired using Leica...

Morphological variations of acorn among and within the groups of Quercus species were studied. A total of 617 acorns belonging to 14 species representing all 3 sections of Quercus L. (Fagaceae) in Turkey were examined in this study. Specimens were collected from 47 different populations over both Anatolian and Thrace part of Turkey. Principal component analysis was used to analyze the morpholog...

abstract in this study, two wild iranian crocus species (crocus speciosus and crocus cancellathus) were examined using 16 morphological characters and 13 issr primers on 250 and 25 plant samples, respectively. the highest and lowest coefficient of variations were belonged to the thickness of the petals (71.25%) and the leaf length (15.08%), respectively. cluster analysis based on morphological ...

The variations of the hyoid bone has a great significance for surgical procedures of neck region, and in forensic medicine for evidence of strangulation or hanging, which causes fractures. The aim of this study was to investigate the morphological and morphometrical variations of the hyoid bone in Anatolian population. A total of 60 adult larynx specimens (46 male, 14 female) were dissected to ...
