Sucrose phosphorylase (SPase) can transfer the glucosyl group of sucrose to different compounds and has been widely used in industry. To overcome low thermostability from Leuconostoc mesenteroides ATCC 12291 (LmSP), a method named PROSS was construct mutants with increased thermostability. All variants were screened by measuring their residual activities after heating at 50°C. Then, single poin...

in this paper, at first we have formulated the lowest order constrained variational method for the relativistic case of an interacting fermion system at finite temperature. then we have used this formalism to calculate some thermodynamic properties of liquid in the relativistic regime. the results show that the difference between total energies of relativistic and non-relativistic cases of liqu...

‎in this paper‎, ‎we obtain exact solutions involving parameters of some nonlinear pdes in mathmatical physics; namely the one-‎dimensional modified complex ginzburg-landau equation by using the $ (g^{'}/g) $ expansion method‎, homogeneous balance method, extended f-expansion method‎. ‎by ‎using homogeneous balance principle and the extended f-expansion, more periodic wave solutions expres...

Given a set P of n points in the plane, the order-k Gabriel graph on P , denoted by k-GG, has an edge between two points p and q if and only if the closed disk with diameter pq contains at most k points of P , excluding p and q. We study matching problems in k-GG graphs. We show that a Euclidean bottleneck perfect matching of P is contained in 10-GG, but 8-GG may not have any Euclidean bottlene...

We consider Markovian dynamics modeling open mesoscopic systems which are driven away from detailed balance by a nonconservative force. A systematic expansion is obtained of the stationary distribution around an equilibrium reference, in orders of the nonequilibrium forcing. The first order around equilibrium has been known since the work of McLennan (1959), and involves the transient irreversi...

Herpes simplex virus type 1 (HSV-1) encodes 11 envelope glycoproteins, of which glycoprotein G-1 (gG-1) induces a type-specific antibody response. Variability of the gG-1 gene among wild-type strains may be a factor of importance for a reliable serodiagnosis and typing of HSV-1 isolates. Here, we used a gG-1 type-specific monoclonal antibody (MAb) to screen for mutations in the immunodominant r...

background bipolar disorder is a biological brain disorder which is associated with debilitating fluctuation in mood and adverse effects on patients, their families and society. the importance of genetics and its role in bipolar disorder is a controversial issue to discuss. evidence indicates a relation between the risk of bipolar disorder and specific genes. amongst the genes whose role has be...
