Increasing numbers of children are suffering from hypoxia-related visual impairments such as retinopathy prematurity. This study aimed to investigate whether all trans retinoic acid reverses hypoxia related in retinal vasculature. Oxygen induced model was established mouse and the expression ciliary neurotrophic factor, vascular endothelial growth factor inducible 1 detected. We found that leve...

objective: to assess the effect of heparin binding neurotrophic factor (hbnf) on sciatic nerve regeneration in animal model of rat. methods: seventy-five male wistar rats were divided into five experimental groups randomly (each group containing 15 animals): sham operation group (sham), autograft group (auto), transected control (tc), chitosan conduit (chit) and heparin binding neurotrophic fac...

Royal jelly (RJ) is known to have a variety of biological activities toward various types of cells and tissues of animal models, but nothing is known about its effect on brain functions. Hence, we examined the effect of oral administration of RJ on the mRNA expression of various neurotrophic factors, their receptors, and neural cell markers in the mouse brain. Our results revealed that RJ selec...

It has been shown that abnormalities in axonal transport occur in several mouse models with motoneuron degeneration and also in the human disease amyotrophic lateral sclerosis. In this report, we have examined the potential of neurotrophic factors to act on axonal transport properties in a mouse mutant, progressive motor neuronopathy (pmn). This mouse mutant has been characterized as a "dying-b...

objective(s): occlusal trauma is one of the most common forms of oral biting dysfunction. long-term occlusal trauma could weaken the stomatognathic system; especially damage one’s masticatory muscle. through using the rat model, this study investigated the trophic effect of ciliary neurotrophic factor (cntf) on injured masseter muscle. materials and methods: male wistar rats (n=36) were randoml...

background: the induction of brain-derived neurotrophic factor (bdnf) expression in the hippocampus has shown to play a role in the beneficial effects of resveratrol (rsv) on the learning and memory. the bdnf gene has a complicated structure with eight 5’ noncoding exons (i-ixa), each of which can splice to a common coding exon (ix) to form a functional transcript. estrogens increase levels of ...

conclusions this study shows that bdnf and ngf expression decreases in diabetic neuropathy. however, this decrease can be reversed through endurance training. these results also indicate that endurance training may have a potential role in compensating for neurotrophin deficiency following diabetic neuropathy. objectives this experimental study was designed and carried out at the tarbiat modare...

low glucose condition induces neuronal cell-death via intracellular mechanisms including mitogen-activated protein kinases (mapk) signaling pathways. it has been shown that low glucose medium decreases neuronal survival in cerebellar granule neurons (cgns). in this study, we have examined the activation of jnk, p38kinase and erk1/2 pathways in low glucose medium in cgns. the cgns were prepared ...

background and purpose: brain-derived neurotrophic factor (bdnf) is present in the hippocampus and cerebral cortex in high concentrations and has an important role in development, maintenance and regeneration of the nervous system. the aim of this study was to produce active bdnf in e.coli using transforming plasmid. methods: to construct an expression plasmid of bdnf, a gene coding for it was ...
