Context. Observations with the Hinode spectro-polarimeter have revealed strong horizontal internetwork magnetic fields in the quiet solar photosphere. Aims. We aim at interpreting the observations by means of results from numerical simulations. Methods. Radiative MHD simulations of dynamo action by near-surface convection are analyzed with respect to the relation between vertical and horizontal...

In this study, neural cell sorting of high throughput and high purity is made using two-step separation by combining soft inertial microfluidics and pinched flow fractionation. Both finite element analysis tool and equivalent electric circuits modeling were used to design the microfluidic devices. Separation between neurons and glia cells from rat’s spine cord was demonstrated. To minimize the ...

Two-dimensional polyacrylamide-gel electrophoretic analysis of yeast ribosomal proteins uniformly labelled in vivo with [methyl-3H]methionine and [1-'4C]methionine revealed that four ribosomal proteins are methylated, i.e. proteins S31, S32, L15 and L41. Lysine and arginine appear to be the predominant acceptors of the methyl groups. The degree of methylation ranges from 0.09 to 0.20 methyl gro...

The availability of indispensable amino acids (IAA) modulates protein turnover. More particularly AAI deficiency reduces synthesis while the consequence on proteolysis remains unclear. present study aims to evaluate specific response both and a diet restricted one strictly IAA, either lysine or threonine Sixty-four growing rats were divided into 8 groups (n = 8/group). They fed for 3 weeks isoc...
