3D Characterization of the Influence of Porosity on Fatigue Properties of a Cast Al Alloy
Authors: Caty Olivier , Buffiere Jean‐Yves , Maire Eric , Adrien Jerome 
Published: November 2010

AbstractThree‐dimensional (3D) images of casting defects present in broken and nonbroken fatigue samples of a cast Al alloy (A380–ISO: AlSi8Cu3Fe) have been obtained using laboratory X‐ray tomography. The 3D images have been processed to obtain various parameters (size, distance from the surface, projected area, etc.), for all the defects present in the gage length. 3D finite element meshes have also been generated from the tomographic images in order to compute the stress field at the vicinity of each defect. Correlations between the fatigue properties of the investigated samples and the above mentioned parameters are analyzed in order to elucidate which one seem to be predominant for the studied material.
Metal Nanocrystals with Highly Branched Morphologies
Authors: Lim Byungkwon , Xia Younan 
Published: November 2010

AbstractMetal nanocrystals with highly branched morphologies are an exciting new class of nanomaterials owing to their unique structures, physicochemical properties, and great potential as catalysts, sensing materials, and building blocks for nanoscale devices. Various strategies have recently been developed for the solution‐phase synthesis of metal nanocrystals with branched morphologies, such as multipods and nanodendrites. In this Minireview, the procedures and mechanisms underlying the formation of branched metal nanocrystals are presented in parallel with recent advances in synthetic approaches based on kinetically controlled overgrowth, aggregation‐based growth, heterogeneous seeded growth, selective etching, and template‐directed methods, as well as their properties for catalytic or electrocatalytic applications.

Published: November 2010

AbstractAmyloid plaques are one of the hallmarks of Alzheimer's disease (AD). The lack of specific probes that can detect individual senile plaques in AD has prompted the development of magnetic resonance imaging (MRI) probes. In this study, based on DTPA‐gadolinium (III) and congo red (CR), a novel specific MRI probe precursor CR‐BSA‐(Gd‐DTPA)n was successfully synthesized. Its ability to bind to amyloid plaques was evaluated by brain sections from APP/PS1 transgenic mice. Its specificity for Aβ plaques was further demonstrated by immunohistochemistry (IHC) staining with the monoclonal antibody to the Aβ protein. Meanwhile, the amyloid deposits detected by the CR‐BSA‐(Gd‐DTPA)n were matched to the amyloid deposits detected by Aβ specific antibody. We also found that a few amyloid‐like deposits which was not detected by IHC. The findings indicated that the probe perhaps could detect the neurofibrillary tangles (NFT) similar to the effect of CR itself, and this will be verified in future experiments. The works suggested that the Aβ protein‐specific magnetic resonance contrast agent precursor CR‐BSA‐(Gd‐DTPA)n can be used as a potential fluorescence and MR multi‐modal imaging probe precursor to display individual senile plaques in AD.

Microsurgical Anatomy of Lumbosacral Nerve Rootlets for Highly Selective Rhizotomy in Chronic Spinal Cord Injury
Authors: Zhou Mou‐Wang , Wang Wen‐Ting , Huang Hong‐Shi , Zhu Gen‐Ying , Chen Ya‐Ping , Zhou Chang‐Man 
Published: November 2010

AbstractIt is known that selective sacral roots rhizotomy is effective for relieving the neurogenic bladder associated with spinal cord injury. The goal of this study is to review the surgical anatomy of the lumbosacral nerve rootlets and to provide some morphological bases for highly selective sacral roots rhizotomy. Spinal cord dissections were performed on five cadavers under surgical microscope. At each spinal cord segment, we recorded the number, diameter and length of the rootlets, subbundles and bundles from the L1 to S2 spinal segments, and the length of the dorsal/ventral root entry zone. Peripheral nervous system myelin was examined by immunohistochemistry. We found: (1) the ventral or the dorsal root of the lumbosacral segment of the spinal cord was divided into one to three nerve bundles and each bundle was subdivided into one to three subbundles. Each subbundle further gave out two to three rootlets connected with the spinal cord; (2) there were no significant differences in the number of rootlets within the L1 to S2 segments, but the size of rootlets and the length of nerve roots varied (P < 0.05); and (3) the more myelinated fibers a rootlet contained, the larger transection area it had. The area of peripheral nervous system myelin positive cells and the total area of rootlets were correlated (P < 0.001). Thus, during highly selective sacral roots rhizotomy, the ventral and dorsal roots can be divided into several bundles of rootlets, and we could initially distinct the rootlets by their diameters.

Angiogenesis of the Frozen‐Thawed Human Fetal Ovarian Tissue at the Early Stage after Xenotransplantation and the Positive Effect of Salviae miltiorrhizae
Authors: Wu Dandan , Lei Yaning , Tong Yuehong , Tang Fei , Qian Yunying , Zhou Ying 
Published: November 2010

AbstractCryopreserving ovarian tissue followed by transplantation has been suggested to preserve fertility for young cancer survivors. However, ischemia in the early stage after transplantation causes massive follicle loss. The aim was to investigate the histological and ultrastructural characteristics of the frozen‐thawed human fetal ovarian tissue after xenotransplantation and the effects of Salviae miltiorrhizae (SM) on the angiogenesis. The human fetal ovarian tissues were frozen‐thawed, xenografted into the immunodeficient nu/nu mice, and then collected 2, 7, and 28 days after transplantation. SM was administered. Compared with that of the frozen‐thawed ovarian tissue, the total follicle number of the grafts was greatly reduced. Nearly half of the primordial follicles were damaged at different levels on day 2. Moreover, edema was prevalent in the stroma during the first week after the graft, especially on day 2. The microvessel density of the grafts was increased on day 2, reached a peak on day 7, and then declined on day 28. Both healthy primordial follicle proportion and the total healthy primordial follicles pool in the SM group were significantly higher than those of the control group (P = 0.003 and P = 0.001). We found a statistically significant difference of microvessel density between the two groups on day 2 (P < 0.001). In the frozen‐thawed fetal ovarian grafts, angiogenesis has been begun on day 2, and the first week is the critical time for the grafts to regain their function, in which SM can facilitate graft vascularization and improve the preservation of primordial follicles.

Limit of hazard rate function of coherent system with discrete life
Authors: Mi Jie 
Published: November 2010

AbstractIn this paper we study the limiting behavior of the hazard rate function of a coherent system 𝒮 whose components are independent and have discrete lifetimes. The lifetime of the system 𝒮 can be viewed as the lifetime of a parallel system consisting of the series systems obtained from the minimal paths of 𝒮. If we appropriately interpret the ‘strongest’ minimal path(s) of the system 𝒮, it will be shown that the limit of the hazard rate functions of 𝒮 is the same as that of the ‘strongest’ path(s) of 𝒮. The application of the main results are also provided. Copyright © 2010 John Wiley & Sons, Ltd.
A Photoenzymatic System for Alcohol Oxidation
Authors: Gargiulo Serena , Arends Isabel W. C. E. , Hollmann Frank 
Published: November 2010

AbstractA photocatalytic regeneration approach for the oxidized nicotinamide cofactors NAD(P)+ is presented. By simple irradiation with visible light, the rate of flavin‐mediated NAD(P)H oxidation is accelerated by two orders of magnitude. Catalytic use of the flavin is straightforward under aerobic conditions. Combined with alcohol dehydrogenases, photoenzymatic oxidation schemes are obtained allowing for selective, O2‐driven oxidation of primary and secondary alcohols. The simplicity and practical applicability of this oxidation approach is demonstrated in the oxidative lactonization of 1,4‐ and 1,5‐diols. Under nonoptimized conditions, total turnover numbers of 170 and 340 are achieved for the nicotinamide cofactor and the flavin catalyst, respectively.
T4 Virus‐Based Toolkit for the Direct Synthesis and 3D Organization of Metal Quantum Particles
Authors: Hou Li , Gao Faming , Li Na 
Published: November 2010

AbstractOne of the challenges in building superstructures based on small metal particles is producing stable interparticle separation. Herein, we present a novel assembly method based on the use of the T4 bacteriophage capsid as a scaffold for the construction of 3D monodisperse metal–particle arrays. The highly regular and symmetrical protein surface of the T4 capsid allows the site‐directed adsorption and subsequent reduction of metal ions, thus permitting the growth of metal particles in situ to enable them to exist at a quantum size with a high degree of monodispersity. Both these characteristics contribute to a great improvement in the electrocatalytic activity of the patterned noble‐metal particles. Organized magnetic particles as small as 2–4 nm still maintain an observable ferromagnetic behavior, which makes them promising for a variety of possible biomedical applications.
