1. Introduction Liver lesions stem from a variety of causes ranging from benign to malignant. The ability to efficiently and accurately differentiate these lesions as malignant or benign using non-invasive medical imaging is important to patient treatment and outcome. Contrast-enhanced computed tomography (CT) imaging is the dominant technology used for liver lesion diagnosis [1]. This modality...

This study concerns to evaluate the morphological and flavonoid variations, and chemotaxonomy among seven Scutellaria species. The limits of Scutellaria species were disturbed by different factors including hybridization and polymorphism. For this purpose, 39 Scutellaria accessions were collected from different natural habitats of Zagros region, Iran. A total of 15 quantitative and 20 qualitati...

Morphological levelings are powerful operators and possess a number of desired properties for the construction of nonlinear scale space image representations. In this paper, a comparison between levelings constrained by di erent multiscale markers namely, reconstruction openings, alternate sequential, isotropic and anisotropic di usion lters was performed. For such a comparison a relation betwe...

AIMS To examine how accurately immunohistochemical markers discriminate between pancreatobiliary and intestinal-type adenocarcinomas in the pancreatic head and to explore the prognostic importance of these markers among each of these histological types. METHODS AND RESULTS Histopathological features of 114 consecutively resected adenocarcinomas of pancreatobiliary (n = 67) and intestinal (n =...

We used scanning electron microscopy to study the morphological surface patterns of cells that cover the attached gingiva and intervestibular papilla of the human oral gingival epithelium. Five patterns are described on the basis of the overall appearance of morphological surface markers: microvilli, parallel, fingerprint, reticular and pitted. Statistical analyses detected significant differen...

Background: Mesenchymal stem cells (MSC) are a very promising transplantable stem cell source for a variety of cell replacement therapies. As the main source of MSC is bone marrow (BM), most of studies have been done on BM-derived MSC (BM-MSC). Umbilical cord (UC)-derived MSC (UC-MSC) which are recently introduced, is one of the good alternative source for these cells. The objective of this stu...

—Idaho populations of Eriogonum shockleyi are divided taxonomically into 2 varieties: E. shockleyi var. packardae, which is endemic to Idaho, and the typical variety, which is widespread in the western United States. Recent morphological investigations of E. shockleyi in Idaho have identified potentially reliable morphological characters for field identification of the subspecific taxa. This pa...

A sample set of 21 rice varieties composed of 20 BRRI developed modern rice varieties and one local variety was selected to detect the genetic variation by using 13 morphological traits, 14 physiological traits and 34 SSR markers. All these three methods divide the varieties into five clusters and showed that there exist high genetic variations among the genotypes. Cluster analysis showed that ...

iran, with a long history of apricot cultivation is one of the most important apricot producers in the world. centuries of sexual reproduction via seed, have developed many divergent variations of apricots in iran. however, unfortunately there is no comprehensive report available concerning its diversity and genetic make-up. in this study, 39 iranian apricot cultivars as well as accessions, nat...
