objective: despite availability of an effective vaccine against hepatitis b virus (hbv), the global prevalence of this virus infection has not diminished significantly. contrary to numerous other human viruses, hbv does not have the ability to propagate in cell culture. however, infectious virus has been produced by transfection of human hepatoma cells with plasmids that contain full length hbv...

the present study was aimed to examine the association of bovine follicular stimulating hormone gene polymorphism with sperm quality traits including sperm volume (sv), sperm concentration (spco), total sperm (ts), fresh sperm motility (fsm), total fresh motile sperm (tfms), post thaw sperm motility (ptsm), total post thaw motile sperm (tptms), number of produced payout (npp), number of fresh m...

two dogs with generalized seizures were evaluated. the dogs were diagnosed with traumatic intracranial hemorrhages based on the history, neurological examinations, and magnetic resonance imaging (mri) of the brain. treatment was started with oxygen, prednisolone and anticonvulsant agents. no further seizure activity was observed after treatment in both dogs, however cushing reflex was detected ...

background: there are many reports regarding to effects of granulocyte colony-stimulating factor (g-csf) and stem cell factor (scf)alone in liver repair .but conflicting data have been reported regarding the role of growth factors such as g-csf and scf in the liver regeneration system. also, there is not such data regarding to effects of co-administration both of g-csf and scf in the liver dama...

stem cells are generally defined as clonogenic cells capable of both self-renewal and differentiation. probably the best method for long-term preservation of spermatogonial stem cells is cryopreservation. in this study, effects of follicle stimulating hormone and testosterone on viability rate of cryopreserved spermatogonial stem cell after thawing were investigated. sertoli and spermatogonial ...

introduction: various neuroregenerative procedures have been recently employed along with neurorehabilitation programs to promote neurological function after spinal cord injury (sci), and recently most of them have focused on the acute stage of spinal cord injury. in this report, we present a case of acute sci treated with neuroprotective treatments in conjunction with conventional rehabilitati...
