abstract：:The aim of this investigation was to compare olfactory functions of patients suffering from Parkinson's disease (PD) and Alzheimer's disease (AD). Olfactory threshold, odor identification ability and odor memory performance were assessed in 21 non-demented PD patients and in 22 AD patients. Both patient groups were im...

abstract：:Regarding the chemotaxis of sperms, new insights have been gained during the last 20 years. Olfactory receptors are expressed on the flagellar midpiece of human spermatogenic cells. One of them, OR1D2, is also expressed in the olfactory epithelium. This receptor has been suggested to play a role in sperm chemotaxis an...
