The in Silico Insight into Carbon Nanotube and Nucleic Acid Bases Interaction.

Background: To explore practical applications of carbon nanotubes (CNTs) in biomedical fields the properties of their interaction with biomolecules must be revealed. Recent years, the interaction of CNTs with biomolecules is a subject of research interest for practical applications so that previous research explored that CNTs have complementary structure properties with single strand DNA (ssDNA).

Objectives: Hence, the quantum mechanics (QM) method based on ab initio was used for this purpose.

A Comparative Serological Study of Toxoplasmosis in Pregnant Women by CLIA and ELISA Methods in Chalus City Iran.

Background: Toxoplasmosis is the most common disease in humans and animals (zoonosis) caused by the protozoan parasite Toxoplasma gondii. The disease is usually appeared as asymptomatic in immunocompromised individuals but its most common symptom is lymphadenopathy. Shortly before or during the first trimester of pregnancy, this disease can be transferred to the fetus and cause serious infection in the fetus.

Respiratory symptoms and pulmonary function testes in lead exposed workers.

Background: The exposure to noxious agwents such as lead my cause lung disorders.

Objectives: In the present study, pulmonary function tests and self-reported respiratory symptoms in lead exposure workers were compared with matched control subjects.

Materials And Methods: The frequency of respiratory symptoms were evaluated in a sample of 108 lead exposure workers and 100 control subjects with similar age using a questionnaire including questions on respiratory symptoms in the past year.
