we estimated the genetic diversity and population structure of persian sturgeon across six regions of caspian sea along the coast of iran using eight dna microsatellite loci. full genotypes were obtained for 195 individuals of persian sturgeon. significant differences were detected between a. persicus specimens collected from sefidrud river (p≤0.0001) and those collected from the southern fishe...

Background: Argas persicus has a great importance for health and veterinary, it can transmit many infectious agents such as Borrelia anserina (avian spirochetosis) and Aegyptianella pullorum. Distinguishing Argasidae due to close morphological relationship is difficult. OBJECTIVES: In the present study, we performed molecular analyses based on PCR and sequencing of Amplicon derived from 16S rRN...

Late Triassic plant macro-remains are extremely rare in an equatorial belt stretching across the North of Gondwana from northern South America to Arabia. Located between Laurussian floral province and South, this large area, is almost entirely lacking palaeobotanical data. Thus, region special interest our knowledge provincialism distribution. Based on impressions ferruginous crusts, first reco...

A study on motility of spermatozoa of the Persian sturgeon, Acipenser persicus were carried out. The time of relative cessation of sperm activity was evaluated using microscopic observation. Sperm was activated with three different swimming medium, freshwater pH 7.5, and two different buffered saline solutions, pH 7.5. Total period of the motility of A. persicus spermatozoa was shorter in fresh...

This study was established to contrast the effectiveness of red onion (Allium cepa) juice and green tea (Camellia sinenses) extract on lipid oxidation and sensory characteristics of refrigerated sturgeon fillets (Acipenser persicus). For this, fillets were tumbled in 1%, 2.5%, and 5% (v/v) aqueous solutions of onion Juice (OJ) and tea extract (TE), and then stored for up to 8 days at 4°C. Chemi...

species composition, relative abundance, absolute abundance and biomass of sturgeon species were studied during the years 2008-2009. eighty five stations were covered in the stratified random sampling design in depths less than 1om using 9m bottom trawl (head line) and in depths more than 10m using 24.7m bottom trawl (head line). more than 70 specimens of acipenser persicus were caught during t...

Outdoor dust covers a shattered range of microbial agents from land over transportation, human flora, which includes pathogen and commensals, airborne the environment. Dust aerosols are rich in bacterial communities that have major impact on health living environments. In this study, outdoor samples roadside barricades, safety walls, fences (18 samples) were collected Abu Dhabi, UAE diversity w...
