Relationship Between G-Quadruplex Sequence Composition in Viruses and Their Hosts
A subset of guanine-rich nucleic acid sequences has the potential to fold into G-quadruplex (G4) secondary structures, which are functionally important for several biological processes, including genome stability and regulation of gene expression ...

Homologous recombination risk in baculovirus expression vector system
The baculovirus expression vector system (BEVS) is widely used for producing recombinant proteins. To achieve high expression level of recombinant proteins, baculoviral elements, such as enhancers, promoters, signal peptide coding sequences and 3′-UTR ...

Technique for Fixation of Semitendinosus to the Patella in Patellar Tendon Reconstruction
Chronic patellar tendon injuries are rare yet challenging to treat. Timing of surgery and graft choices are debatable. Many techniques and methods of fixation have been described with pros and cons.

Harnessing a Refinement Theory to Compute Loop Functions
AbstractWe consider a while loop on some space S and we are interested in deriving the function that this loop defines between its initial states and its final states (when it terminates). Such a capability is useful in a wide range of applications, including reverse engineering, software maintenance, program comprehension, and program verification. In

The sampled-data asynchronous control problem for T-S fuzzy systems is investigated in this paper. Firstly, a new fuzzy Lyapunov functional that contains the fuzzy line integral function and an improved looped functional is constructed, in which two new ...

Arabidopsis PCH2 Mediates Meiotic Chromosome Remodeling and Maturation of Crossovers. [PDF]
Meiotic chromosomes are organized into linear looped chromatin arrays by a protein axis localized along the loop-bases. Programmed remodelling of the axis occurs during prophase I of meiosis.

Stability and Stabilization of Sampled-Data Systems via Inter-Sample State Prediction
This paper investigates improved stability and stabilization criteria for sampled-data systems by explicitly incorporating inter-sample state prediction. Unlike most existing studies, which rely on the conventional zero-order hold and thereby neglect the

On loop functions in the theory of topological LA-semigroups
In theory of topological LA-semigroups, we introduce the concepts of LA-loop functions for LA-lifting functions in theory of LA-fibrations. We prove that the LA-lifting function and LA-loop function for any LA-fibration are not necessarily unique.

Analysis of Loop Function of Dihydrofolate Reductase
To elucidate the role of flexible loops in the stability and function of Escherichia coli dihydrofolate reductase (DHFR), glycine-67, glycine-121, and alanine-145 in the three different loops were substituted with several amino acids by site-directed mutagenesis.
