Introduction: Research has shown that gold nanoparticles (AuNPs) can damage the physiological processes of brain tissue. Given the antioxidant properties of gingerol (GING), this study aimed to determine the protective effect of 6-gingerol on hippocampal levels of brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), DNA oxidative damage, and the amount of Bax and Bcl2 apoptosis ...

Objective(s):Althoughroutinely applied in assisted reproductive technology, human sperm cryopreservation is not a completely successful procedure. Adverse effects of cryopreservation on the fertilization capacity, motility, morphology, and viability of spermatozoa have been proven; cryopreservation has also shown a role in sperm DNA fragmentation and infertility. The post-thaw survival of sperm...

It is well known that various markers of the cholinergic synapse are altered in Alzheimer's Disease. Much interest is currently focussing on the evaluation of the possible efficacy of certain growth factors, especially nerve growth factor (NGF), to reduce or reverse cholinergic neuronal losses. Here we report that other growth factors (epidermal growth factor and insulin-like growth factor I) a...

C57BLKS db/db (db/db) mice develop a neuropathy with features of human type 2 diabetic neuropathy. Here, we demonstrate that these mice develop transient mechanical allodynia at the early stage of diabetes. We hypothesized that nerve growth factor (NGF), which enhances the expression of key mediators of nociception (i.e. substance P [SP] and calcitonin gene-related peptide), contributes to the ...

Misdirection of axons after nerve injury impairs successful regeneration of adult neurons. Investigations of axon guidance in development have provided an understanding of pathfinding, but their relevance to regenerating adult axons is unclear. We investigated adult mammalian axon guidance during regeneration after peripheral nerve injury and focused on the effects of the prototypic guidance mo...

C57BLKS db/db (db/db) mice develop a neuropathy with features of human type 2 diabetic neuropathy. Here, we demonstrate that these mice develop transient mechanical allodynia at the early stage of diabetes. We hypothesized that nerve growth factor (NGF), which enhances the expression of key mediators of nociception (i.e. substance P [SP] and calcitonin gene<related peptide), contributes to the ...

The effects of intermale aggressive behavior induced by social isolation on the level of nerve growth factor (NGF) mRNA and protein were investigated in central and peripheral mouse tissues. A large increase in NGF mRNA and protein was observed in hypothalamus, with no changes in cerebral cortex, hippocampus, and cerebellum. No change in NGF mRNA levels was found in heart, spleen, vas deferens,...

Deer antlers are the only mammalian organs that can fully regenerate each year. During their growth phase, antlers of red deer extend at a rate of approximately 10 mm/day, a growth rate matched by the antler nerves. It was demonstrated in a previous study that extracts from deer velvet antler can promote neurite outgrowth from neural explants, suggesting a possible role for Nerve Growth Factor ...

In the primary olfactory pathway axons of olfactory neurons (ONs) are accompanied by ensheathing cells (ECs) as the fibres course towards the olfactory bulb. Ensheathing cells are thought to play an important role in promoting and guiding olfactory axons to their appropriate target. In recent years, studies have shown that transplants of ECs into lesions in the central nervous system (CNS) are ...
