The neutron yield is determined to be 18.4±2.1 per carbon by integrating the neutron flux over the entire water volume. The corresponding simulation values are performed by Geant4 code with three models to compare with the experimental results. The comparison shows that the calculated result with the INCL model is in good agreement with the experimental data.展开更多

In addition, the currently existing therapeutics only offer temporary symptomatic relieves. Therefore, further research and development of more efficacious and disease-modifying agents for the prevention, treatment and restoration of AD will have tremendous value from both scientific, and economic standpoints. Over the past few years, our series of studies have identified several highly promising anti-AD dimeric leads, with disease-modifying potentials. In this presentation, the latest progress on the neuroprotective and disease modifying effects and the underlying mechanisms of those candidates will be comprehensively illustrated and discussed.展开更多

Phytomolecules having multiple targeting anticancer activity are in high demand and there is less documentation or information available on these metabolites. It is evident that mushrooms are became the store houses of new anticancer molecules and mushrooms like Agaricus blazei, Antrodia camphorate, Albatrellus confluens, Bolteus badius, Cordyceps militaris, Clitocybe maxima, Funalia trogii, Grifola frondosa, and Inocybe umbrinella, are some of the medicinal mushrooms reported for their cytotoxic activity. Cytotoxic molecules like lentinan, grifolin, illudin-S, psilocybin, ganoderic acid, theanine, and hispolon, have been isolated from various mushroom species. However, studies have been limited only to in vitro cytotoxic mechanisms and very few trials have been conducted to prove the clinical efficacy of these drug leads. Hence, the current review focuses on new anticancer metabolites isolated from various mushrooms having multiple targeting mechanisms in cancer. However, an extensive research is needed to define the biosynthesis and clinical mechanism of these multiple acting metabolites. This review provides a platform for researchers new anticancer drugs and to bring out potent multiple acting anticancer newer drugs.展开更多
