This article reviews various initiator used to synthesize high molecular weight (MW >10,000 g/mol) of polylactic acid (PLA) through ring-opening polymerisation (ROP) lactide. ROP has been chosen as the best method in producing PLA. On other hand, stannous octoate (Sn(Oct)2) reported catalyst for method. Many researchers have studied that rate with presence only Sn(Oct)2 is slow compared lact...

We have sequenced a methionine tRNA from mosquito mitochondria, and examined its structure using nucleases S1 and T1 under non-denaturing conditions. The sequence is highly homologous to a putative initiator methionine tRNA gene from Drosophila mitochondria. Its anticodon stem contains a run of three G-C base pairs that is characteristic of conventional initiator tRNAs; however, nuclease S1 ana...

A dencentralized consensus protocol refers to a process for all nodes in a distributed system to collect the information/status from every other node and reach a consensus among them. Two classes of decentralized consensus protocols have been studied before: the one without an initiator and the one with an initiator. While the one without an initiator has been well studied in the literature, it...

Caspases execute cell death. The mechanism of effector caspase activation primarily involves reorganization of active site loops following the activation cleavage. The Induced Proximity hypothesis, originally proposed to explain the activation of initiator caspases, has recently been reinterpreted to be proximity-driven dimerization of initiator caspases, and consequently their activation. The ...
