the aim of this study was to investigate the hemagglutination properties of caprine herpesvirus-1(cphv-1) and their application for cphv-1 antigen detection and evaluation of the dynamics of postinfectious/vaccine antibody production. cphv-1 hemagglutination activity was proved only with mouseerythrocytes, pbs and saline solutions at 4°c and 22°c. in vaccinated animals, goats and bucks withresp...

introduction: neuropathic pain syndromes are changes resulting from damage to neuronal pathways that are characterized by spontaneous burning sensation with accompanying allodynia and hyperalgesia. since the treatments of neuropathic pain are poorly understood and existing treatments are often ineffective, it is important to increase our understanding of the neuropathic pain states in order to ...

increasing growth of population leads to increase in human activities such as agriculture and industry, which these activities increasing and irregular usage of fertilizers, pesticides and insecticides result in soil and groundwater pollution. meanwhile, vulnerability assessment can play important role in the management of polluting activities. in this research a new method has been proposed fo...

to compensate for some inferior properties of recycled papers, application of processing chemical aids such as chitosan can be quite effective in the wet end section of papermaking. in this study, the performance of chitosan biopolymer, individually or associated with nanobentonite was investigated as wet end additive on recycling process of white cuttings. for this purpose, the performance of ...

background: parkinson’s disease (pd) is a common neurodegenerative disease resulting from the degeneration of dopaminergic (da) neurons in the substantia nigra pars compacta (snc). increasing evidence demonstrated that mice treated intranasally with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (mptp) suffered impairments in motor functions associated with disruption of da neurons in snc conceiv...

hybrid rice varieties are potentially higher yielding than the best inbred varieties and perform better under adverse conditions of drought and salinity. one of the major impediments for seed production of hybrid rice is incomplete panicle exsertion in the cytoplasmic male sterile lines. the unexserted spikelets which are left inside the flag leaf sheath remain unfertile. this research was focu...
