Abstract Knowing the age of individuals in a population is crucial to devise appropriate conservation strategies, especially on endangered long-lived species such as sea turtles. Sea turtles do not have external morphologic characters that indicate their age; therefore, has been estimated by indirect methods biometric measurements or skeletochronological analysis. Previous studies determined tu...

the males of the three species of bumblebees, bombus (thoracobombus) ruderarius (müller), b. (t.) persicus radoszkowskiand b. (t.) mesomelas gerstaecker collected from vikan village, qazvin province and their male labial gland secretions were analyzed by gas chromatography/ mass spectrometry (gc/ms) and components of their extracts were identified. the major compounds were a complex mixture of ...

the expanding phenomenon of dieback is caused by the reaction of trees against the harmful biotic and a biotic factor that lead to dying of shoots and branches of trees from upper crown to lower crown. this phenomenon spreads throughout the leaves and branches and all parts of the plant and may finally lead to the death of the plant. this study aimed to identify species dieback especially carpi...

acinic cell carcinoma arising in salivary glands is a rare tumor, accounting for 2% to 5% of the primary neoplasms of the parotid gland. when these tumors are well-differentiated, the neoplasia has innocuous aspect, due to the similarity to normal parotid tissue. this makes the diagnosis difficult. initially the malignancy of this tumor was uncertain; however, recent studies have declared it as...

The reliability of any survey of biodiversity through geologic time depends on the rigor and consistency by which taxa are recognized and samples are identified. The main goal of the Neogene Marine Biota of Tropical America (‘NMITA’) project is to create an online biotic database (http://nmita.geology.uiowa.edu) containing images and synoptic taxonomic information that are essential to collecti...

Focal segmental glomerulosclerosis (FSGS) is a heterogeneous clinicopathological entity. Two frameworks for the classification of FSGS have been described: etiologic and morphologic. The etiologic classification is distinguished among genetic, adaptive, virus-associated, drug-induced, and idiopathic types. Morphologic classification is commonly referred to as the Columbia classification publish...

In spite of the taxonomy of the Aspergillus species of the Nigri Section being regarded as troublesome, a number of methods have been proposed to aid in the classification of this Section. This work aimed to distinguish Aspergillus species of the Nigri Section from foods, grains and caves on the basis in Polyphasic Taxonomy by utilizing morphologic and physiologic characters, and sequencing of ...
