Escherichia coli has dispensable genome regions and eliminating them may improve cell use by reducing unnecessary metabolic pathways and complex regulatory networks. Although several strains with reduced genomes have already been constructed, there have been no reports of strains constructed with deletions assayed for influence on growth. To retain robust growth and fundamental metabolic pathwa...

Freeze-thaw injuries of rabbit corneas were treated with mesodermal growth factor (MGF) in organ culture and the repair of the endothelium followed by light microscopic examination of endothelial whole mounts. MGF-treated corneas showed an increased number of mitotic figures. In addition, MGF accelerated the rate of cell hypertrophy, formation of spindle-shaped cells, and the rate of their migr...

An R-module A is called GF-regular if, for each a ∈ A and r ∈ R, there exist t ∈ R and a positive integer n such that r(n)tr(n)a = r(n)a. We proved that each unitary R-module A contains a unique maximal GF-regular submodule, which we denoted by M GF(A). Furthermore, the radical properties of A are investigated; we proved that if A is an R-module and K is a submodule of A, then MGF(K) = K∩M GF(A...

AIM Mangiferin (Mgf), a promising therapeutic polyphenol, exhibits poor oral bioavailability. Hence, apt delivery systems are required to facilitate its gastrointestinal absorption. The requisite details on its physicochemical properties have not yet been well documented in literature. Accordingly, in order to have explicit insight into its physicochemical characteristics, the present work was ...

We go on in the program of investigating the removal of divergences of a generical quantum gauge field theory, in the context of the Batalin-Vilkovisky formalism. We extend to open gauge-algebræ a recently formulated algorithm, based on redefinitions δλ of the parameters λ of the classical Lagrangian and canonical transformations. The key point is to generalize a well-known conjecture on the fo...

Prior evidence supporting the direct observation of phosphorane intermediates in enzymatic phosphoryl transfer reactions was based on the interpretation of electron density corresponding to trigonal species bridging the donor and acceptor atoms. Close examination of the crystalline state of beta-phosphoglucomutase, the archetypal phosphorane intermediate-containing enzyme, reveals that the trig...

Automatic ground filtering for Light Detection And Ranging (LIDAR) data is a critical process for Digital Terrain Model (DTM) and three-dimensional urban model generation. Although researchers have developed many methods to separate bare ground from other urban features, the problem has not been fully solved due to the similar characteristics possessed by ground and non-ground objects, especial...

Order statistics arising from exponentiated gamma (EG) distribution are considered. Closed from expressions for the single and double moments of order statistics are derived. Measures of skewness and kurtosis of the probability density function of the rth order statistic for different choices of r, n and /theta are presented. Recurrence relations between single and double moments of r...

BACKGROUND Accumulating evidence indicates that mangiferin (MGF), a natural xanthone, by virtue of its antioxidant and antiinflammatory properties is neuroprotective. Here we sought to verify the cytoprotective role of MGF on cultured rat primary mesencephalic cells exposed to 6-hydroxydopamine (6-OHDA) in vitro, and the MGFs anti-inflammatory potential in mouse model of ketamine-induced schizo...

Flexible, uniform and surface smooth iron-based metallic glassy fibers (MGFs) were fabricated by a melt-extraction method. There was large magnetic anisotropy in the MGF. Our experimental results indicated that this large magnetic anisotropy was related to the unique magnetic domain structures in the MGF.
