introduction: this study was carried out to investigate calcific tissue formation against mineral trioxide aggregate (mta) after pulp capping. materials and methods: the pulps of six teeth from four dogs were exposed and capped with mta. after extraction each tooth was sectioned into halves. each half was then further sectioned in the mesiodistal or buccolingual direction. calcified tissue of t...

morphological and histochemical study of the abomasal epithelium in camel (camelus dromedarius) wascarried out by light and scanning electron microscopes. the lining of the abomasum was divided into fourregions, i.e. cardiac, pseudocardiac, fundic and pyloric. our investigation revealed that the cardiac andpseudocardiac regions occupy a wide part of the abomasum in camel and it reaches approxim...

the study reports some preliminary investigations on the template free synthesis of a scantly investigated polyaniline (pani) derivative-phenylenediamine (pda) by template free method in the presence of oxalic acid (oa) (dopant), using ammonium persulfate as oxidant. polymerization of phenylenediamine (pda) was confirmed by the ft-ir as well as uv–visible studies. the morphology of phenylenedia...

Cryptomys hottentotus has no access to dietary or endogenous sources of cholecalciferol (D3). Serum concentrations of calcifediol (25(OH)D3) were undetectable (< 5 ng/ml) and calcitriol (1,25(OH)2D3), although detectable in plasma, was at a low concentration (31.40 (SEM 3.06 pg/ml). Despite their naturally impoverished vitamin D status, these animals exhibited highly efficient mineral absorptio...
