Some biological aspects of semen were investigated in the Persian sturgeon, Acipenser persicus, by determination of seminal plasma indices (ionic composition and osmolality), sperm density and their relationships with sperm motility. The osmolality of seminal plasma ranged from 42.00 to 111.00 mOsmol Kg-1. The concentrations of Sodium (Na+), Potassium (K+), Chloride (Cl-), Calcium (Ca2+) and Ma...

The major groups of biochemical compounds (proteins, lipids, carbohydrates, chitin, nucleic acids and nucleotides) have a distinct functional role and, therefore, incorporation of biochemical interpretations into stoichiometric analysis would improve our current understanding of species life histories and their interactions. A review of the stoichiometric composition of the main biochemical com...

Background: Thymus deanensis is a known aromatic plant which grows widely in Iran and many mediterranean regions. In previous studies composition of essential oils of many species of Thymus genus reported which they were rich of phenols like Thymol and Carvacrol. Methods: Water distilled essential oils from aerial parts of Thymus deanensis var. deanensis from three different localities in Iran...
