Oxide and metal complex catalysts for low temperature gas-phase oxidation of carbon monoxide by air oxygen lose their activity under the action chemical poisons such as SO2, H2S, PH3, H2O. We have developed a highly efficient Wacker-type catalyst in which carrier is fiber material (CFM), precursor was cellulose hydrate. For catalyst, there are no studies on effect catalytic poisons, namely SO2 ...

Microtubule poisons are widely used in cancer treatment, but the factors determining the relative efficacy of different drugs in this class remain obscure. In this study, we identified the NIMA kinase Nek4 in a genetic screen for mediators of the response to Taxol, a chemotherapeutic agent that stabilizes microtubules. After Taxol treatment, Nek4 promoted microtubule outgrowth, whereas Nek4 def...

Indian Snake-poisons, their Nature and Effects By A. J. YVali, m. d. f Dond.), Fellow of the Royal College of Surgeons of England ; of the Medical Staff H. At.'s Indian Army* This work, which is dedicated to Sir Joseph Fayrer, is in many respects a distinct advance upon our knowledge of snake-poisons, and especially so in those chapters in which the characteristic physiological effects of the v...

Spindle poisons, such as paclitaxel and vinblastine, exert their potent anti-neoplastic effects through activation of the spindle assembly checkpoint (SAC), thereby arresting cells in mitosis. Unfortunately, only certain cancers are susceptible to these drugs, and many patients fail to respond to treatment. We review the pathways that are triggered by spindle poisons and highlight recent studie...

background & aim: energy is one of important debates in agriculture ecology and for this reason; the ratio of output and input energy in different agriculture ecosystems has been calculated. if one can reduce, input energy level into farms through the indices like poisons, fertilization, tractor energy and lab our force. in addition to the net income of the farmers, this issue would play a ...
