Reaction of the rodent carcinogen acrylonitrile (AN) at pH 7.0 for 10 and/or 40 days with 2'-deoxyadenosine (dAdo), 2'-deoxycytidine (dCyd), 2'-deoxyguanosine (dGuo), 2'-deoxyinosine (dIno), and thymidine (dThd) resulted in the formation of cyanoethyl and carboxyethyl adducts. The adducts isolated were 1-(2-carboxyethyl)-dAdo (1-CE-dAdo), N6-CE-dAdo, 3-CE-dCyd, 7-(2-cyanoethyl)-Gua (7-CNE-Gua),...

The order Noctilucales or class Noctiluciphyceae encompasses three families of aberrant dinoflagellates (Noctilucaceae, Leptodiscaceae and Kofoidiniaceae) that, at least in some life stages, lack typical dinoflagellate characters such as the ribbon-like transversal flagellum or condensed chromosomes. Noctiluca scintillans, the first dinoflagellate to be described, has been intensively investiga...

Introduction: Poroscopy is a method of identification in which the characteristics of sweat pores are compared from different aspects. These pore openings are present along the friction ridges found on the distal end of digits, palms and soles in the hands and feet. Materials amd Methods: This study enrolled 100 Iranian males from the Fars family who resided in Khorasan Razavi Province. T...

This paper introduces a novel approach to leverage features learned from both supervised and self-supervised paradigms, improve image classification tasks, specifically for vehicle classification. Two state-of-the-art learning methods, DINO data2vec, were evaluated compared their representation of images. The former contrasts local global views while the latter uses masked prediction on multi-l...

A group of individuals with identical preferences must make a decision under uncertainty about which decision is best. Before the decision is made, each agent can privately acquire a costly and imperfect signal. We discuss how to design a mechanism for eliciting and aggregating the collected information so as to maximize ex-ante social welfare. We first show that, of all mechanisms, a sequentia...

Background: Rat prostate gland which is used in various investigation has considerable morphological differences with other mammals. There are few reports about its structure. So, this study was carried on for determining of histomorphological structure of rat prostate. Materials and Methods: Five healthy adult male rats with average weight 20 ± 180 g and approximately 3 - 3.5 months age were s...

Background: Hormonal disorders such as hyperactivity of testosterone are one of the causes of infertility. In the present study, effects of Urtica dioica root extract on histomorphometric changes of rat testes induced by high dose testosterone was investigated. Materials and Methods: For this purpose, 25 male mature wistar rats were divided in 5 groups, group 1 was control, group 2 received tes...
