The Use of Cationic Polymers as Primary Coagulants in Water
In applying organic polymers to the removal of UV absorbing compounds (used as a measure of trihalomethane precursors), a reservoir water was best treated with a high MW polydiallyldimethy-lammonium chloride (poly DADMAC). Similar results were obtained for a river water, where a cationic polyacrylamide (CPAM) of high charge was also effective.

Acute neuroprotective synergy of erythropoietin and insulin
Erythropoietin (EPO) and insulin-like growth factor I (IGF-I) are cytokines that inhibit neuronal apoptosis. However, their maximal antiapoptotic effect, even at high concentrations, is observed only when neurons are pretreated for several hours before insult. Here we show that simultaneous administration of EPO and IGF-I (EPO+IGF-I) eliminates the preincubation period required to prevent N
