Selectivity to visual stimulus orientation is a basic cortical functional property believed to be crucial for normal vision. Maturation of this neuronal property requires neural activity. Still, it is unclear what might be the molecular basis for such activity-dependent processes and whether activity has an instructive or permissive role in development of(More)
Nerve growth factor (NGF) stimulates 5-HT3 receptor expression although the mechanism(s) responsible for this effect are unknown. We report the nucleotide and deduced amino acid sequences of a nearly complete rat 5-HT3 receptor subunit and use the sequence to develop a reverse transcription-polymerase chain reaction (RT-PCR) assay that measures 5-HT3 mRNA.(More)
A number of substituted amine-carboxyborane esters were examined for their hypolipidemic activity in rodents. Trimethylamine-carbomethoxyborane, Me3NBH2C(O)OMe, was observed to be the most effective hypolipidemic agent in the rodent at the low dose of 8 mg/kg/d. This agent effectively increased the high density lipoprotein (HDL) cholesterol content and(More)
A new combined stain is described for the study of cell types in the fish pituitary. Tissues are prepared by fixing in formol-sublimate and then embedded in paraffin wax. Tissue is sectioned at 5 micron and than stained sequentially with performic acid-alcian blue, periodic acid-Schiff, orange G, and acid fuchsin. As a result of this procedure acidophils(More)
The pituitary of roach, Rutilus rutilus (L.), is pear-shaped and situated in the sella turcica. It is characterised by a large pars nervosa, which penetrates deep into the other regions, splitting the proximal pars distalis. Spatial localisation of nerve fibre types and glandular cell types occurs. Using a variety of staining techniques six glandular cell(More)
— A Quadrotor, is a unique kind of UAV's that uses four-fixed rotors, with two rotors per axis (each axis is orthogonally aligned with the other) powered by four motors to lift and propel the aircraft. The scheme of controlling a Quadrotor is done by varying the speed of the motors relative to each other, also the dynamics of the Quadrotor demand constant(More)
