the effects of pesticide endosulfan (an organochlorine compound), on the ovaries of bluegill fish (lepomis macrochirus) were studied. exposures for 24 hs with histological preparations at 25% (0.25 î¼g/l), 75 % (0.75 î¼g/l), and 100 % (1 î¼g/l) sub lethal concentrations were examined. the control contained an abundance of the different stages of oocytes (oocytes i, ii, iii, and iv) and had an i...

The macrocyclic complexes of biological importance with power transition metals are synthesized by template methodology leading to the formation of the complex [MLX] X2; where L is macrocyclic ligand derived from 3,4-diaminotoluene, 2,4-thiazolidinedione, M=Cr (III) and Fe(III) X is Cl-, CH3COO- or NO3_.Characterisation of these complexes are through with the assistance of elemental analyses(CH...

Ca(V)2.2 (N-type) and Ca(V)1.2 (L-type) calcium channels gate differently in response to membrane depolarization, which is critical to the unique physiological functions mediated by these channels. We wondered if the source for these differences could be identified. As a first step, we examined the effect of domain exchange between N-type and L-type channels on activation-deactivation kinetics,...
