Enzyme replacement therapy has been used successfully in many lysosomal storage diseases. However, correction of brain storage has been limited by the inability of infused enzyme to cross the blood-brain barrier. The newborn mouse is an exception because recombinant enzyme is delivered to neonatal brain after mannose 6-phosphate receptor-mediated transcytosis. Access to this route is very limit...

silver nanoparticles (ag nps) have been widely used as new potent antimicrobial agents in cosmetic and hygienic products. present study compares the tissue levels of ag nps in different organs of guiana pigs quantitatively after dermal application and analysis the morphological changes and pathological abnormalities on the basis of the ag nps tissue levels. before toxicological assessments,the ...

Let $R$ be a commutative ring with identity and $mathbb{A}(R)$ be the set   of ideals of $R$ with non-zero annihilators. In this paper, we first introduce and investigate the principal ideal subgraph of the annihilating-ideal graph of $R$, denoted by $mathbb{AG}_P(R)$. It is a (undirected) graph with vertices $mathbb{A}_P(R)=mathbb{A}(R)cap mathbb{P}(R)setminus {(0)}$, where   $mathbb{P}(R)$ is...

High-dimensional dependence modeling remains a crucial challenge in quantitative project cost and time risk analysis. Building complete mathematically consistent correlation matrix becomes unrealistically restrictive as the number of uncertain performance units (i.e., activity times costs) increases, regardless using empirical data or with subjective judgment. This article presents pair additiv...

Objective(s): Silver nanoparticles (Ag NPs) are not only specific physical and chemical properties but also are considered for their antibacterial activity and ecofriendly.Materials and Methods:In this study a simple, cost effective biologically method for Ag+reducing to Ag NPs using Echinops extractas a stabilizer, and reducing agent.Ag NPs were analyzed using UV-Vis spectrometry,TEM, XRD and ...

Objective(s): Ghrelin is a brain-gut peptide involved in substance and energy metabolism. To confirm the hypothesis that ghrelin might be involved in non-alcoholic fatty liver disease (NAFLD), a rat NAFLD model was established and the changes of ghrelin were explored.Materials and Methods: The rats were divided into control and NAFLD gro...

Background: Nanoparticles (NPs) are colloidal systems with particles ranging from 10 to 100 nm in diameter. Because of their large surface-volume ratio, NPs are biologically active materials that could interact with biomolecules and microorganisms, enter into the cells, and affect the metabolic functions. The study aimed to biosynthesize silver nanoparticles (Ag-NPs) from Capparis spinosa fruit...

in this study, the effects of different concentrations of bulk and nano-sized ag on seed germination and seedling growth of canola were investigated in a randomized completely design with four replications. the experimental treatments included four concentrations of bulk agno 3 (10, 100, 500 and 1000 ppm), four concentrations of nanosized ag (10, 100, 500 and 1000 ppm), and the control without ...
