The vomeronasal system (VNS) mediates pheromonal communication in mammals. From the vomeronasal organ, two populations of sensory neurons, expressing either Gai2 or Gao proteins, send projections that end in glomeruli distributed either at the rostral or caudal half of the accessory olfactory bulb (AOB), respectively. Neurons at the AOB contact glomeruli of a single subpopulation. The dichotomi...

effects of sodium salt solutions on physicochemical and sensory characteristics of refrigerated persian sturgeon (acipenser persicus) fillets during 12 days of storage were investigated. fillets were dipped in solutions (2.5% w/v) of sodium acetate (sa), sodium lactate (sl), sodium citrate (sc) and distilled water (as control) for 10 minutes and then packaged. an assessment of tbars, ffa, ph, h...
