This study was designed to characterize morphometric sperm subpopulations in normozoospermic men by using different statistical methods and examining their suitability to classify correctly different sperm nuclear morphologies present in human ejaculates. Ejaculates from 21 normozoospermic men were collected for the study. After semen collection and analysis, samples were prepared for morphomet...
study of fishes on aquatic ecosystems in many respects, including ecology, behavior, biology, conservation and management of water resources, exploitation of resources and training are important. so in the autumn 2011, the population structure of barilius mesopotamicus was studied. in this order, 69 samples of the mentioned fish from seimareh (34 samples), changoleh (20 samples) and siahgave (1...
the genus allactaga is a group of rodents with five morphospecies distributed in the iranian plateau. in order to conduct a taxonomic revision at the species level, 27 individuals were collected in the iranian plateau from localities typical of each species. phylogenetic relationships within species were analyzed using cytochrome oxidase subunit i and morphometric data. maximum parsimony, maxim...
BACKGROUND Fine needle aspiration cytology (FNAC) is a reliable and reproducible diagnostic technique for thyroid lesions with certain limitations. Computed morphometric methods have been introduced with a view to improve the diagnostic yield of thyroid aspirates. However, a review of the existing literature revealed conflicting reports regarding morphometric parameters in thyroid neoplasms. ...
Comparative analysis was performed to discriminate a hybrid produced from the crossbreed of Pangasianodon hypophthalmus (♀) and Pangasius nasutus (♂) and its parental species based on morphology appearances and morphometric characters. Morphological structures of the vomerin and palatal teeth varied between the hybrid and both parents. Results of the univariate analysis revealed 22 morphometric...
The present study was conducted on the comparison of morphometric and meristic factors among Alosa caspia (Eichwald, 1838) populations in the southern Caspian Sea basin. A total of 285 Alosa caspia specimens were caught from three localities, from west to the east of Caspian Sea including Guilan (Bandar Anzali), Mazandaran (Sari) and Golestan (Miankale) provinces. Thirty morphometric and ten me...
