Translation of "Conclusive" in Japanese

And despite enormous scientific endeavor, we have not yet found a conclusive cure.

科学者たちの膨大な努力にも関わらず 未だ 決定的な治療法は見つかっていません

Today, their efforts have paid off and they are in possession of conclusive evidence, an achievement which is indeed commendable.

今日、その努力が報われ彼らが決定的な証拠を掴んだ事は賞賛に値します。
