Olfactory cues play an important role in the behaviour of fish, such as the procurement of food,recognition of sex, defence against predators, parental behaviour, and orientation [13]. Olfaction isa mediator of chemical signals and is involved in diverse teleost behaviour [10]. The olfactory organof fish is the only vertebrate organ in which nerve cells are directly exposed to the aquatic ecosystem...

The olfactory epithelium of Scatophagus argus (Linnaeus) was investigated by light and scanning electron microscopy. The elongated olfactory organ is made up of 20 to 22 primary lamellae arranged on both sides of the narrow median raphe. Sensory and non-sensory regions are located separately on each lamella...

The olfactory organ of Oreochromis nilotica was studied by means of light and scanning electron microscopes. The oval shaped olfactory apparatus consists of 19–20 lamellae radiating from a central raphe...

Even with normal aging process, changes in myocardium occur and may modify lusitropic function of the heart. These changes include a remodeling of the myocardial interstitium, an increase in myocardium collagen content and a prominence of myocardial fibrosis, probably due to the activation of the renin–angiotensin–aldosterone axis [1]. This heart aging phenomenon surely affects the diastolic function of our patients and needs to be readily and easily assessed...
