The perception of periodical change in photoperiodic conditions by photosensory organs is the first step to initiating reproductive activity in fish. To date, it is not known how photoperiodic cues are endogenously transduced to the endocrine network of the brain-pituitary-gonad axis after the perception of photoperiodic stimuli. Because dopamine (DA)(More)
Nowadays corruption in Bangladesh has become a social affliction. The baleful paw of corruption has been spread each and every spheres of people's life in Bangladesh. It is unfortunate for all Bangladeshis' that Bangladesh has ranked as the worlds' most corrupted country for five sequent years (2001-2005) according to the report of Transparency(More)
Polyclonal antibodies were generated against ADP-ribosylarginine hydrolase (AAH), using recombinant fusion protein of rat AAH and glutathione-S-transferase as a immunogen, and affinity-purified. Western blotting showed that the antibodies recognized in mouse brain homogenate a single protein with a molecular mass of 38 kDa, the expected size for mouse AAH.(More)
In the neuroendocrine system controlling fish reproduction, dopamine (DA) acts as a gonadotropin inhibitory factor and plays a role in regulating gonadal development of certain species. The present study examined the effects of chemical destruction of dopaminergic neurons in the brain on DA production and ovarian development in the sapphire devil(More)
Fish are faced with a wide range of hydrostatic pressure (HP) in their natural habitats. Additionally, freshwater fish are occasionally exposed to rapid changes in HP due to heavy rainfall, flood and/or dam release. Accordingly, variations in HP are one of the most important environmental cues for fish. However, little information is available on how HP(More)
