background & aim: ferulago angulata sub. carduchorum (locally name: chavir or chavil) is an important medicinal plant in iran. the powder of aerial parts of this plant contains variety of components with different therapeutical effects such as antioxidant activities (aoa). this study was conducted to investigate the effect of dietary supplementation powder of aerial parts of this plant on t...

Two Hundred and six day old Fulani Ecotype chicks (FEC)were used to investigate the effect of feeding two types diet (Chick starter Broiler formulated meet standard nutritional requirement pullets broiler chicks) on growth traits performance from O 8 weeks. The contained 23% Crude Protein (CP) 3000Kcal/kg Metabolizable Energy (ME), Chick 21% CP 2800Kcal/Kg ME. measured were body weight (BW), le...

Studies on sex-specific segregation in foraging behaviour and trophic niche have been focussed large dimorphic seabirds, with less information small monomorphic species. Here, we used mini-GPS loggers, habitat suitability models, stable isotopes to assess sex differences the movements, spatial distribution, ecology of Boyd’s shearwaters Puffinus lherminieri boydi Raso Islet (16°36’ N, 24°35’ W)...

we studied the hepatotoxic effects of a deltamethrin containing formulation (decis®) on developing em-bryo of gallus domesticus. fertilized eggs were immersed in three different concentrations of deltamethrin (12.5, 25 and 50 mg/l) for 60 min at 37 ˚c prior to incubation (ed 0) and on the 4th day of incubation (ed 4) and incubated till embryonic day (ed) 16. exposure to 50 mg/l of deltamethrin ...

The reactivation of chicken erythrocyte nuclei in chick-mammalian heterokaryons resulted in the activation of chick globin gene expression. However, the level of chick globin synthesis was dependent on the mammalian parental cell type. The level of globin synthesis was high in chick erythrocyte-rat L6 myoblast heterokaryons but was 10-fold lower in chick erythrocyte-mouse A9 cell heterokaryons....

introduction: in order to study the morphogenetic role of cell death in the development, a series of comparative studies on the structure of the interdigital membrane of chick (with free digit) and duck (webbed digits) embryos was done. materials and methods: chick embryos ranging from 6.5 to 10 days of incubation (stag 30-36 h-h) and duck embryos ranging from 8.5 to 12 days of incubation at 12...

introduction: the objective of this study was to evaluated effect of retinoic acid (ra) on the tibia osteogenesis in the chick embryos. materials and methods: for this purpose 0.75mg ra dissolved in 2ml dimthylsulfoxide (dmso) was droped on the limb bud of chick embryos at sixth day of incubation. the osteogenesis of tibia in ra-treated embryos were compared with normal control and dmso-treated...

Inactive nuclei of chick erythrocyte resume RNA synthesis and increase in volume and dry mass in heterokaryons made by virus-induced fusion of human tumor cells (HeLa) with chick erythrocytes. Nuclear growth is due primarily to migration of human macromolecules into the chick nucleus. Human nucleoplasmic antigens were detected in the nucleoplasm and human nucleolar antigens were detected in the...

A total of 1,800 incubating eggs produced by a commercial flock of Cobb broiler breeders was used to determine the effects of storage duration (3 or 18 d) on spread of hatch and chick quality. Chick relative growth (RG) at the end of 7 d of rearing was also determined as a measure of the chick performance. Chick quality was defined to encompass several qualitative characteristics and scored acc...

   Background: In this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. Methods: The developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of ...
