in this research work, a novel parallel manipulator with high positioning and orienting rate is introduced. this mechanism has two rotational and one translational degree of freedom. kinematics and jacobian analysis are investigated. moreover, workspace analysis and optimization has been performed by using genetic algorithm toolbox in matlab software. because of decreasing moving elements, it i...

introduction multiple dentigerous cysts are rare and mostly associated with syndromes. case presentation the present case report is unique, as the dentigerous cysts enclosed the lateral incisor, canine, first and second premolars of the mandible and were accompanied by a complex odontoma, instead of first mandibular molar. conclusions multiple unilateral nosyndromic dentigerous cysts with compl...

abstractinteraction of ni complex(salen= n, n´-ethylene bis(salicylideneimine)) with hen egg-white lysozyme (hewl) was studied by absorption spectroscopy, competitive binding study and thermal denaturation study. the protein binding affinity of ni complex was found to be (3.0×103m−1). the binding plot obtained from the absorption titration data gives a binding constant of 2.4 (± 0.3)×103 m-1. i...

Lysicamine is a natural oxoaporphine alkaloid, which isolated from traditional Chinese medicine (TCM) herbs and has been shown to possess cytotoxicity to hepatocarcinoma cell lines. Reports on its antitumor activity are scarce because lysicamine occurs in plants at a low content. In this work, we demonstrate a facile concise total synthesis of lysicamine from simple raw materials under mild rea...
