introduction: spinal cord injuries (sci) lead to permanent irreversible functional deficits.  poor prognosis of patients is the motivation of searching a treatment for the chronic injury.  planting stem cells provides us with a promising strategy. in the meanwhile, the use of olfactory ensheathing cells (oecs) has shown very good results.  this study aims at evaluating the effect of transplante...

Synopsis Intra- and inter-sexual communications are vital to the survival reproductive success of animals. In species that cycle in out breeding or other physiological condition, sensory function can be modulated optimize communication at crucial times. Little is known, however, about how widespread this plasticity across taxa, whether it occurs multiple senses both sexes within a species, what...

Introduction: Cell transplantation is one of the main strategies for spinal cord injury repair. As OECs of the olfactory mucosa can be obtained by simple biopsy in all individuals without affecting their smell sensation, OECs considered as a promising candidate for autologous transplantation in the nervous system injury, especially for spinal cord repair. Thereby in the current study OECs wer...

Background: Olfactory ensheathing glia (OEG) has been shown to have a neuroprotective effect after being transplanted in rats with spinal cord injury. This study was conducted to determine the possible beneficial results of olfactory mucosa transplantation (OMT) which is a source of OEG on functional recovery and axonal regeneration after transection of the sciatic nerve. Methods: In this study...

Introduction: The Questionnaire for Olfactory Dysfunction (QOD) is a self-reporting olfactory-related quality of life questionnaire. The aim of this study was to determine the reliability and validity of the Persian version of this questionnaire. Materials and Methods: One hundred and thirteen patients with olfactory problems were enrolled in this study. The English version of the QOD was first...

Intense apoptoses occur during the morphogenesis period of embryonic development. In the adult, and in the absence of genotoxic aggressions or degenerative pathologies, normal apoptoses strongly decrease in most organs and become restricted to self-renewing tissues containing progenitor stem cells, allowing continuous cell replacement. This is the case in the olfactory neuroepithelium that line...

We identified a large family of putative odorant-binding protein (OBP) genes in the genome of Drosophila melanogaster. Some of these genes are present in large clusters in the genome. Most members are expressed in various taste organs, including gustatory sensilla in the labellum, the pharyngeal labral sense organ, dorsal and ventral cibarial organs, as well as taste bristles located on the win...

Remarkably little is known about the molecular mechanisms that drive sexual behavior. We have identified a new gene, quick-to-court (qtc), whose mutations cause males to show high levels of male-male courtship. qtc males also show a novel phenotype: when placed in the presence of a virgin female, they begin courtship abnormally quickly. qtc mutations are striking in their specificity, in that m...
