interleukin (il)-25, a cytokine of il-17 family, can activate p38 mitogen-activated protein kinases(mapk) and nuclear factor(nf)-κb pathways to propagate th2 responses. the allergic rhinitis mouse model was established by stimulating balb/c mouse with ovalbumin (ova). then we detected expression of il-25 and downstream p38mapk and nf-κb. the expression of il-25, p38mapk and nf-κb were detected ...

Feeding rumen bypass polyunsaturated fatty acids (PUFA) affects to Japanese Black cows affects their reproduction, though its influence on superovulatory response in donor cows and conception in recipient cattle has not been well studied. Here, we investigated the effects of feeding PUFA to Japanese Black cows on blood biochemistry, the numbers of ova and embryos or transferable embryos and pre...

The effects of five different foods including: blood worm, artemia cyst, Artemia mass powder, gammarus mass powder and ordinary commercial food were studied on Siamese fighting fish (Bettasplendens) propagation efficiency during thirty days in a Randomize Totally Design with 4 repeats .Experimental plots had been consisted of twenty 30*30*40 (cm) aquarium which a pair of male and female brood s...

Ram spermatozoa are most susceptible to damage during freezing between the temperatures of -10 degrees C and -25 degrees C. The objectives of the present study were to examine how freezing rate through this critical temperature zone affected the fertility of spermatozoa as assessed in vivo and in vitro. Semen from six adult rams was frozen at two different rates ("fast": 5 degrees C/min from +5...

The immune responses of mice immunized with ovalbumin (OVA) together with killed L. major (KLM) promastigotes as adjuvant were studied. Three doses (5 × 107, 1 × 108 and 2 × 108) of KLM combined with OVA (100 mg) were injected into the groups of C57BL/6 mice. BCG and complete Freund’s adjuvant (CFA) were used as control adjuvants. Lymphocyte proliferation and antibody titers were determined, an...

During 12 months of sampling, from 17 stations, 327 specimens of Soboor fish Tenualosa ilisha, including 120 females, 113 males and 86 immature were caught. Total length (TL) of the fishes was 120-500mm. Maximum diameters of soboor ova 0.795mm and the ova with diameter more than 0.7 mm released at one spawning round. Temporal and spatial distribution of ova diameter corresponding to GSI changes...

Cryopreservation of avian ova and embryos is challenging because of the yolky structure of the egg. As an alternative, with the development of effective cryopreservation protocols, ovarian tissue cryopreservation could be used for cryobanking for birds. Pieces of ovarian tissue of week-old Japanese quail (Coturnix japonica) were frozen at 0.5 degrees C/min in a programmable freezer or vitrified...
