Device-to-Device (D2D) has been a potential technology to improve the sum-rate of cellular networks, especially in local communication. By reusing the resource of cellular user equipment (UE), D2D can enhance the spectrum efficiency, but at the cost of introducing extra co-channel interference. In this paper, we adopt a resource reusing mechanism in which multiple D2D pairs can share multiple r...

The essential involvement of water in most fundamental extra-cellular and intracellular processes of proteins is critically reviewed and evaluated in this article. The role of water in protein behavior displays structural ambivalence; it can protect the disordered peptide-chain by hydration or helps the globular chain-folding, but promotes also the protein aggregation, as well (see: diseases). ...

Phorbol-12,13-dibutyrate, epidermal growth factor, and insulin raised the intracellular pH ([pH]i), presumably through the activation of a Na+/H+ antiporter. Addition of amiloride or replacement of extra-cellular Na+ by choline which abolishes the cytoplasmic alkalinization prevented the stimulation of hexose transport by these agents. Furthermore, monensin, a Na+/H+ ionophore which increases t...

The present study is concerned with the production of glucose oxidase (GOD) from thermophilic Penicillium sp. in a 250 mL shake flask. Fourteen different strains of thermophilic Penicillium sp. were isolated from the soil and were screened for glucose oxidase production. IIBP-13 strain gave maximum extra-cellular glucose oxidase production as compared to other isolates. The effect of submerged ...

Aneuploidy is a condition frequently found in tumor cells, but its effect on cellular physiology is not known. We have characterized one aspect of aneuploidy: the gain of extra chromosomes. We created a collection of haploid yeast strains that each bear an extra copy of one or more of almost all of the yeast chromosomes. Their characterization revealed that aneuploid strains share a number of p...

Abstract We formulate an active-gel theory for multicellular migration in the extra-cellular matrix (ECM). The cells are modeled as active, polar solvent, and ECM a viscoelastic solid. Our enables to analyze dynamic reciprocity between migrating their environment terms of distinct relative forces alignment mechanisms. linear stability homogeneously ECM. predicts that, consequence cell-matrix al...

expansin proteins are a type of cell-wall loosening proteins which able to cell wall expansion in ph-dependent manure without hydrolyze of main cell wall structures. the arabidopsis expa1 exhibit guard cell specific expression and trigger the stomatal movements. the objectives of this study were to transfer the atexpa1 gene into tobacco plants and evaluate their phonotypic effects on transforme...
