The in vitro effect of 17α, 20β-Dihydroxyprogesterone on the maturation of Persian sturgeon (Acipenser persicus) oocytes for 7, 10, 12, 24 and 30th hours of incubation were investigated. Blood serum, testosterone (T), progesterone (P4) and 17-β estradiol concentrations were measured using enzyme-linked immuno-sorbent assay (ELISA). The oocytes were incubated in SIS, RM2, L-15 and PSACF media in...

Platelet aggregation inhibitory effect and anticoagulant properties of fractions separated from the venoms of Cerastes persicus fieldi and Echis carinatus were investigated. The partial fractionation was performed on a Sephadex G-100 column. Two fractions separated from Cerastes persicus fieldi showed anti platelet aggregation activity on ADP (200 µM)-induced platelet aggregation (ca 80% inhibi...

background and objectives: betulinic acid (ba), oleanolic acid (oa) and ursolic acid (ua) are well-known pentacyclic triterpenoids (pts), which are produced by plants. they possess a variety of beneficial effects including anti-inflammatory, hepatoprotective, antitumor, anti-hiv, antimicrobial, gastroprotective, and antihyperlipidemic activities. in the present study, quantitative determination...

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...
