In this study, a mesoporous silica nanoparticle (MSN)-based nerve growth factor (NGF) delivery system has been successfully embedded within an electroactive polypyrrol (Ppy). The spherical particles with approximately 100 nm diameter possess a large surface-to-volume ratio for the entrapment of NGF into the pores of MSNs while retaining their bioactivity. Direct incorporation of MSN-NGF within ...

Several mesoporous silica nanoparticle (MSN) contrast agents have been synthesized using a co-condensation method to incorporate two different Gd3+ complexes at very high loadings (15.5-28.8 wt %). These MSN contrast agents, with an MCM-41 type pore structure, were characterized using a variety of methods including SEM and TEM, nitrogen adsorption measurements, thermogravimetric analysis (TGA),...

OBJECTIVE We hypothesize that controversial effects of angiotensin II (Ang II) are attributable to its regulation of reactive oxygen species (ROS) and ROS-dependent signaling. METHODS AND RESULTS Coronary collateral growth (CCG) was stimulated in normal (WKY) and syndrome X (JCR) rats by transient/repetitive ischemia (RI). Blood flow was measured in the normal (NZ) and the collateral-dependen...

We give an alternative construction of the duality between finite group actions and group gradings on rings which was shown by Cohen and Montgomery in [1]. This duality is then used to extend known results on skew group rings to corresponding results for large classes of group-graded rings. Finally we modify the construction slightly to handle infinite groups. Introduction. In the first section...

Abstract A finite group G G is called an MSN-group if all maximal subgroups of the Sylow are subnormal in . In this article, we investigate structure groups such that a non-MSN-group even order which every subgroup MSN-group. addition, determine minimal simple whose second MSN-groups.

and Applied Analysis 3 Definition 1.11 see 4 . Let f and g be two self-mappings from a G-metric space X,G into itself. Then the mappings f and g are said to be weakly compatible if G fgx, gfx, gfx 0 whenever G fx, gx, gx 0. Proposition 1.12 see 1 . Let X,G be a G-metric space. Then, for all x, y, z, a in X, it follows that i if G x, x, y 0, then x y z; ii G x, y, z ≤ G x, x, y G x, x, z ; iii G...

In this paper, we propose search algorithms using multiple autonomous and cooperative mobile sensor nodes (MSN). Our goal is to minimize the total search time and the travel distance of MSNs in a given search area while enabling cooperation among the MSNs and tolerating possible failures of one or more MSNs. We first describe a Lane Based Search (LBS) strategy in which each mobile sensor node i...

Formally, given a set of n homogenous or heterogeneous mobile sensors {s1, s2, ..., sn} that are capable to acquire m physical attributes {a1, a2, ..., am} from their environment at every discrete time instance t (i.e., data has a temporal dimension), an implicit or explicit mechanism that enables each si (i ≤ n) to move in some multi-dimensional Euclidean space (i.e., data has one or more spat...

This study was conducted to assess the effects of feed particle size (FPZ) and crumble size (CZ) of starter diet on growth performance parameters, carcass characteristics, and small intestinal histomorphology in broiler chicks. Three hundred and sixty male Ross 308 chicks were randomly distributed in a completely randomized design with 3 ´ 2 factorial arrangement consist of three screened FPZs ...
