Abstract This paper looks at the history of Tosu using 'forward reconstruction'. It concludes that Proto-Ersuic changed *-im to *-am already before its breakup as a unity, but ‘brightening’ *-a- -i- took place independently in and Lizu-Ersu. In this brightening did not target labial (or velar) initial words lacking an inherited medial *-j-. A number changes probably preceded brightening, namely...

Proto-oncogenes are the genes that have potential to transform normal cells into cancer as a result of mutations. They usually contain encoding proteins whose function is inhibit cell differentiation, stimulate division, and prevent death cells. While prognosis regarding proto-oncogene may occur at varying phases cancer, accuracy identification method always questionable. The standard procedure...
