in this study, rainbow trout (oncorhynchus mykiss) eggs were treated with effective doses of  daenensis thyme, thymus daenensis (20, 10 and 5 mgl-1) and mentha, mentha longifolia (10, 5 and 2.5 mgl-1), during incubation period (20 days) until hatching for 30 minutes per every other day as constant flow bath treatment method. the mortality level in normal control (without any treatment) was sign...

Carbenicillin and cefotaxime, two antibiotics commonly used for excluding Agrobacterium tumefaciens during plant transformation, were tested for their bacteriostatic effects as well as for their effects on plant regeneration in adventitious root explants of papaya following co-culture with Agrobacterium. A washing step with sterilized distilled water two days after co-culture enhanced the bacte...

rodlet cells are frequently found in teleost fishes and although their role in organisms is not completely understood. the occurrence of these cells are related to stress and may undergo changes in contaminated environments, thereby allowing their use as biomarkers. this hypothesis is tested in the present study. thirty specimens of oreochromis niloticus were divided into three groups, two grou...

Cucumis melo L. is one of the most economically important horticultural crops worldwide. However,   low plant regeneration frequency of this plant during genetic transformation is  the  major hurdle for  applying biotechnological approaches. Hence, this study aimed to evaluate the effect of 6-benzyladenine (BA), cefotaxime (CTX), kanamycin (KAN), and indole-3-acetic acid (IAA) on the regenerati...

The present research aimed to determine acute toxicity and evaluate the effect of sub-lethal concentrations of diazinon on some haematological and immunological parameters of Barbus sharpeyi by the Organization for Economic Cooperation and Development methods. Juvenile B. sharpeyi were exposed to 0, 5%, 10% and 25% 96h LC50 concentrations of diazinon for 21 days. Blood samples were taken after ...

The endocannabinoid 2-arachidonoylglycerol (2-AG) mediates retrograde synaptic suppression. Although the mechanisms of 2-AG production are well characterized, how 2-AG is degraded is less clearly understood. Here we found that expression of the 2-AG hydrolyzing enzyme monoacylglycerol lipase (MGL) was highly heterogeneous in the cerebellum, being rich within parallel fiber (PF) terminals, weak ...

Hydrodynamic performance of gas microbearings, fabricated with deep X-ray lithography and electroplating, will be presented in this article. Static performance in terms of load parameters and attitude angles was calculated using Molecular Gas Lubrication (MGL) theory. Threshold speed and allowable rotor mass were calculated to investigate safe operating conditions of the fabricated gas microbea...
