Xylose reductase from the thermophilic fungus Talaromyces emersonii: cloning and heterologous expression of the native gene (Texr) and a double mutant (Texr K271R + N273D) with altered coenzyme specificity
Xylose reductase is involved in the first step of the fungal pentose catabolic pathway. The gene encoding xylose reductase (Texr) was isolated from the thermophilic fungus Talaromyces emersonii, expressed in Esch...

Networks Synchronizability, Local Dynamics and Some Graph Invariants
The synchronization of a network depends on a number of factors, including the strength of the coupling, the connection topology and the dynamical behaviour of the individual units. In the first part of this w...

Complete synchronization and delayed synchronization in couplings
We consider a general coupling of two identical chaotic dynamical systems, and we obtain the conditions for synchronization. We consider two types of synchronization: complete synchronization and delayed synch...

Open AccessSignificance of glycolytic metabolism-related protein expression in colorectal cancer, lymph node and hepatic metastasis
Colorectal cancer (CRC) is one of the most common malignancies and a leading cause of cancer death worldwide. Most cancer cells display high rates of glycolysis with production of lactic acid, which is then ex...

Full-Commanding a Network: The Dictator
A network of chaotic dynamical systems may synchronize. For some networks there is the possibility that, coupling a new node to the network, the synchronization will be commanded by that new node. That possibi...
