Apoptosis-linked gene-2 (ALG-2) encodes a 22 kDa Ca(2+)-binding protein of the penta EF-hand family that is required for programmed cell death in response to various apoptotic agents. Here, we demonstrate that ALG-2 mRNA and protein are down-regulated in human uveal melanoma cells compared to their progenitor cells, normal melanocytes. The down regulation of ALG-2 may provide melanoma cells wit...

In this paper, we first characterize reflexive one-sided A -submodules U of a unital operator algebra A in B(H ) completely. Furthermore we investigate the invariant subspace lattice Lat R and the reflexive hull Ref R, where R is the submodule generated by rank-one operators in U ; in particular, if L is a subspace lattice, we obtain when the rank-one algebra R of Alg L is big enough to determi...

We consider algorithms for learning functions f : X ! Y , where X and Y are nite, and there is assumed to be no noise in the data. Learning algorithms, Alg, are connected with ?(Alg), the set of prior probability distributions for which they are optimal. A method for constructing ?(Alg) from Alg is given and the relationship between the various ?(Alg) is discussed. Improper algorithms are ident...

abstract background: lymphoproliferative disorders are among the most serious and potentially fatal complications of chronic immunosuppression in kidney transplant recipients. the principle risk factors for development of ptld are the degree of overall immunosuppression and the ebv serostatus of the recipient. in this study, the risk of ptld in kidney transplant recipients who received anti- ly...

Excessive toxic metals are commonly found in polluted water bodies. This study aimed to synthesise kenaf-based adsorbents for the adsorption of lead (II) ions. The physical and chemical characteristics kenaf (KNF) core fibre were determined using field emission scanning electron microscope (FESEM), thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FTIR). further synthes...

Biodegradation of polyesters driven by enzymes is considered as one the most effective way degradation these materials, a to control plastics accumulation in environment. In this study, we present two different strategies tune enzymatic PBS films triggered lipase from Pseudomonas cepacia. Firstly, kinetics was regulated applying multilayer coats polysaccharide alginate and chitosan (Alg/Chi) fi...

Grafted copolymer (sodium alginate (Na. Alg)- acrylic acid (AcA)– methacrylic (MAcA)) was prepared by the gamma irradiation-induced copolymerization in presence of N, N-methylene bisacrylamide (MBA) as a co monomer crosslinker. The functionality, morphology and thermal stability have been examined using FTIR spectroscopy, SEM, TGA-DTA, respectively. surface grafted shows smooth relatively homog...

Increased water pollution due to the tremendous increase of dye-containing effluent is still a serious problem which, in turn, adversely affects aquatic life and, consequently, balance our ecosystem. The aim this research was investigate whether Ca-ALG/MgO/Ag nanocomposite beads successfully prepared from calcium alginate hydrogels with MgO (Ca-ALG/MgO) doped Ag nanoparticles (Ag NPs) caused ef...

Biopolymers and nanomaterials are an excellent choice for removing heavy metals keeping the environment clean. The hexavalent chromium (Cr6+) (or) chromium-6 is usually produced by various industrial processes, which can be a toxic liquid pollutant. In this study, nanopolymeric compound supplemented with Fe nanoparticle was used in extraction (removal) process of Cr6+ present aqueous solutions....

Calcium phosphate cements (CPC) have been widely investigated as bone substitutes, owing to their attractive features in terms of physicochemical and biocompatibility properties. However, the clinical applicability this group biomaterials is still critically limited by its poor strength rheological properties injectability cohesion. The present work aims develop novel composite cement based on ...
