Intravenous Autologous Bone Marrow Mononuclear Cell Transplantation for Stroke: Phase1/2a Clinical Trial in a Homogeneous Group of Stroke Patients (2015)

The goal of this clinical trial was to assess the feasibility and safety of transplanting autologous bone marrow mononuclear cells into patients suffering severe embolic stroke. Major inclusion criteria included patients with cerebral embolism, age 20-75 years, National Institute of Health Stroke Scale (NIHSS) score displaying improvement of ≤ 5 points during the first 7 days after stroke, and NIHSS score of ≥ 10 on day 7 after stroke. Bone marrow aspiration (25 or 50 mL; N = 6 patients in each case) was performed 7-10 days poststroke, and bone marrow mononuclear cells were administrated intravenously. Mean total transplanted cell numbers were 2.5 × 10(8) and 3.4 × 10(8) cells in the lower and higher dose groups, respectively. No apparent adverse effects of administering bone marrow cells were observed. Compared with the lower dose, patients receiving the higher dose of bone marrow cells displayed a trend toward improved neurologic outcomes. Compared with 1 month after treatment, patients receiving cell therapy displayed a trend toward improved cerebral blood flow and metabolic rate of oxygen consumption 6 months after treatment. In comparison with historical controls, patients receiving cell therapy had significantly better neurologic outcomes. Our results indicated that intravenous transplantation of autologous bone marrow mononuclear cells is safe and feasible. Positive results and trends favoring neurologic recovery and improvement in cerebral blood flow and metabolism by cell therapy underscore the relevance of larger scale randomized controlled trials using this approach.

Short‐Term Bioassays for Environmental Mutagens and Carcinogens (1979)

Because an estimated 80 to 90 percent of all human cancers can be traced to environmental causes, including hazardous compounds in drinking water, tests for measuring the effects of the pure compounds and complex mixtures in question are badly needed. The various short‐term bioassays discussed here go a long way toward meeting this need.
Exploiting Multiple Antennas in Cooperative Cognitive Radio Networks (2014)

Recently, a new paradigm for cognitive radio networks has been advocated, where primary users (PUs) recruit secondary users (SUs) to cooperatively relay the primary traffic and in return grant the SUs the right to access the channel. However, all existing studies on such cooperative cognitive radio networks (CCRNs) operate in the temporal domain only, which limits the performance of both PUs and SUs. On the other hand, multiple-input-multiple-output (MIMO) enables transmission of multiple independent data streams in the spatial domain to improve capacity. Taking advantage of the MIMO technique in CCRNs is an unexplored area that we investigate in this paper. We propose a novel MIMO-CCRN framework, which enables the SUs to utilize MIMO techniques to cooperatively relay the traffic for the PUs, while concurrently accessing the same channel to transmit their own traffic. Specifically, we consider two typical network scenarios. For the case of a general PU link and multiple SUs, we provide theoretical analysis for the link rates and then formulate an optimization model based on a Stackelberg game to maximize the utilities of PUs and SUs. In addition, we extend our analysis to a practical cellular network with multiple MIMO-empowered femtocells, and provide an algorithm to find a stable matching of the PUs and SUs. Evaluation results show that high utility gains are achieved by both PUs and SUs by leveraging MIMO spatial cooperation in our proposed framework.
Adhesion and Surface Analysis (1995)

Abstract In the last 25 years, surface sensitive analytical techniques have made a major contribution to our understanding of adhesion phenomena and problems. There are several areas where these techniques have provided important information including the identification of failure modes, the chemistry of a substrate before and after pretreatments, the stability of surfaces and interfaces, the identification of surface contaminants, the interaction across an interface and the nature of interphases. X-ray photoelectron spectroscopy (XPS or ESCA), Auger electron spectroscopy (AES) and static secondary ion mass spectrometry (SSIMS) have proved to be especially useful. Many examples of the usefulness of these techniques are given.

Using a large sample of photoproduced charm mesons from the FOCUS experiment at Fermilab (FNAL-E831), we observe the decay D0-->K+pi- with a signal yield of 149+/-31 events compared to a similarly cut sample consisting of 36 760+/-195 D0-->K-pi+ events. We use the observed ratio of D0-->K+pi- to D0-->K-pi+ (0.404+/-0.085+/-0.025)% to obtain a relationship between the D0 mixing and doubly Cabibbo suppressed decay parameters.

Analytical solutions for the three-dimensional side-fringing field of magnetic recording heads (1988)

Using conical coordinates, and in the limit of small gap length, the three-dimensional boundary value problem for the side-fringing field of beveled recording heads is reduced to two dimensions. This makes it possible to use analytic functions of a complex variable, and find simple expressions, in terms of elementary functions, for the scalar potential and three-dimensional magnetic fringing field. For a given bevel angle, the spectral response for side reading from in-plane and perpendicular magnetization depends on a single dimensionless parameter, and a quasi-exponential falloff of this response is calculated as a function of the bevel angle.
KLAIM: a kernel language for agents interaction and mobility (1998)

We investigate the issue of designing a kernel programming language for mobile computing and describe KLAIM, a language that supports a programming paradigm where processes, like data, can be moved from one computing environment to another. The language consists of a core Linda with multiple tuple spaces and of a set of operators for building processes. KLAIM naturally supports programming with explicit localities. Localities are first-class data (they can be manipulated like any other data), but the language provides coordination mechanisms to control the interaction protocols among located processes. The formal operational semantics is useful for discussing the design of the language and provides guidelines for implementations. KLAIM is equipped with a type system that statically checks access right violations of mobile agents. Types are used to describe the intentions (read, write, execute, etc.) of processes in relation to the various localities. The type system is used to determine the operations that processes want to perform at each locality, and to check whether they comply with the declared intentions and whether they have the necessary rights to perform the intended operations at the specific localities. Via a series of examples, we show that many mobile code programming paradigms can be naturally implemented in our kernel language. We also present a prototype implementation of KLAIM in Java.
Analytic simulation of impact ionization in InAlAs/InGaAs HFET's (2002)

A physical model for InP-based HFET including velocity overshoot and impact ionisation effects has been developed using a novel bias dependent velocity approach. This approach bases on a fit-function to data obtained by Monte-Carlo-simulations and has been carefully transferred to the special conditions in HFET-channels. Since impact ionization occurs at high drain-bias, the variation of the free surface potentials due to selective recess etches and scattering of electrons into the barrier material as predicted by Monte-Carlo-simulations have been taken into account in the evaluation of the quasi-2D-potential and field distribution. However, although the physical understanding is emphasized and only explicit analytic formulas of simple nature will be presented, the simulated output and input characteristics well mirror measured data.

Assessing flowability of small quantities of cohesive powder using distinct element modelling (2013)

The characterisation of cohesive powder flowability is often required for reliable design and consistent operation of powder processes. This is commonly achieved by mechanical testing techniques on bulk powder, such as shear test, but these techniques require a relatively large amount of powder and are carried out at large pre-consolidation loads. Many industrial cases require small amounts of powders to be handled and processed, such as filling and dosing of capsules. In other cases, the availability of testing powders could be a limiting issue. It has been shown that under certain circumstances, indentation on a cohesive powder bed by a blunt indenter can give a measure of the resistance to powder flow (Hassanpour and Ghadiri 2007). In the present work, the ball indentation process is analysed by numerical simulations using DEM in order to investigate the operation window of the process in terms of indenter size and penetration depth. The flow resistance of the assembly, commonly termed hardness, is evaluated for a range of sample quantities and operation variables. A sensitivity analysis of bed height reveals that a minimum bed height of 20 particle diameters is required in order to achieve reliable measurements of hardness. It is also found that indenter sizes with diameters smaller than 16 particle diameters exhibit fluctuations in powder flow stress measurements. As the indenter size decreases, it moves closer to the size of bed particles. Therefore, rearrangements at the single particle level influence the force on the indenter, resulting in fluctuations, and possible compaction.
Fatal and Near-Fatal Complications of Liposuction (1998)

Cosmetic liposuction is considered to be safe and effective in properly selected patients and is widely done as an outpatient or office procedure. When major complications occur, office-based practitioners may refer patients to a hospital emergency department, where medical personnel unfamiliar with this procedure may underestimate the risk of serious infection or other major complications. We present two cases of massive necrotizing fasciitis treated in a burn center after liposuction surgery. One patient died, and the second required lengthy hospitalization, extensive debridement, and split-thickness skin grafting of 22% of the total body surface area. Pain out of proportion to clinical findings is a hallmark of necrotizing fasciitis and should prompt consideration of this entity even in the absence of cutaneous signs of infection. Definitive diagnosis is made by biopsy and rapid section histologic analysis. Liposuction may result in major complications or death. Emergency department physicians or general surgeons may be called upon to manage such complications and should be aware of these risks.

Summary of some recent studies of subsonic vortex lift and parameters affecting the leading-edge vortex stability (1976)

Various subsonic configurations which develop vortex lift are examined herein. Comparisons are made with data and the combination of direct and indirect edge forces through use of the suction analogy. For most configurations, the use of the indirect or augmented vortex lift leads to improved agreement with data. The studies conducted showed that it is possible for the leading-edge vortex to exhibit bursting on a cropped wing and the wing aerodynamic characteristics not show the effect. It was further found that the distributions of leading-edge suction correlate well with the maintenance of vortex flow aerodynamic characteristics. Lastly, a method is presented for relating the initial value of circulation and axial velocity of the leading-edge shed vortex to the wing geometry.
Lewis Acid Catalysis of Second-generation Metallosalen Complexes: An Explanation for Stereochemistry of Asymmetric Hetero Diels-Alder Reaction (2001)

Chloro nitrosyl (R,S)-(salen)ruthenium(II) complex served as a good catalyst for asymmetric hetero Diels-Alder (HDA) reaction of Danishefsky's diene with a wide variety of aldehydes.In contrast with this, (R,R)-(salen)chromium(III) and -manganese(III) complexes well catalyze HDA reaction of simple aldehydes, while (R,S)-(salen)-chromium(III) and -manganese(III) complexes better catalyze HDA reaction of aldehydes bearing a precoordinating group.These features of metallosalen-catalyzed HDA reactions were rationalized by assuming that HDA reaction of aldehydes bearing a precoordinating group would proceed through aldehyde-metallosalen complex which takes cis-βstructure. INTRODUCTIONRecently, optically active metallosalen complexes (hereafter referred to as M-salen complexes) have drawn attention of synthetic chemists for their unique asymmetric catalysis.For example, Mn-, Ru-, and Co-salen complexes catalyze asymmetric oxene or its isoelectronic nitrene and carbene transfer reactions with high enantioselectivity. 1In addition, they serve as excellent Lewis acid catalysts. 2In 1995, we found that high valent (salen)manganese complexes served as a Lewis acid catalyst for asymmetric Diels-Alder reaction at -78 °C. 3 In concurrence with this, Co-and Cr-salen complexes were found to be excellent catalysts for Lewis acid-mediated asymmetric reactions by Jacobsen et al. 4 Among them, Crsalen complex (1) showed high enantioselectivity up to 93% ee at -30 °C in asymmetric hetero Diels-Alder (HDA) reaction of Danishefsky's diene (1-methoxy-3-trimethylsilyloxy-1,3-butadiene) with aldehydes, 4c which provides useful building blocks for organic synthesis. 5,6We, recently, found that second-generation (R,S)-(ON + )Ru-salen complex (2) bearing chiral binaphthyl and ethylenediamine units † This paper is dedicated to Professor Shô Itô on the occasion of his seventy seventh birthday.† This paper is dedicated to Professor Sho Ito on the occasion of his 77th birthday.

Molecular Basis for Zinc Transporter 1 Action as an Endogenous Inhibitor of L-type Calcium Channels (2009)

The L-type calcium channel (LTCC) has a variety of physiological roles that are critical for the proper function of many cell types and organs. Recently, a member of the zinc-regulating family of proteins, ZnT-1, was recognized as an endogenous inhibitor of the LTCC, but its mechanism of action has not been elucidated. In the present study, using two-electrode voltage clamp recordings in Xenopus oocytes, we demonstrate that ZnT-1-mediated inhibition of the LTCC critically depends on the presence of the LTCC regulatory beta-subunit. Moreover, the ZnT-1-induced inhibition of the LTCC current is also abolished by excess levels of the beta-subunit. An interaction between ZnT-1 and the beta-subunit, as demonstrated by co-immunoprecipitation and by fluorescence resonance energy transfer, is consistent with this result. Using surface biotinylation and total internal reflection fluorescence microscopy in HEK293 cells, we show a ZnT-1-dependent decrease in the surface expression of the pore-forming alpha(1)-subunit of the LTCC. Similarly, a decrease in the surface expression of the alpha(1)-subunit is observed following up-regulation of the expression of endogenous ZnT-1 in rapidly paced cultured cardiomyocytes. We conclude that ZnT-1-mediated inhibition of the LTCC is mediated through a functional interaction of ZnT-1 with the LTCC beta-subunit and that it involves a decrease in the trafficking of the LTCC alpha(1)-subunit to the surface membrane.

Combined Planar Measurements of Flow Velocity and Mass Concentration in Shallow Turbulent Flow Part 1: Development of a Planar Concentration Analysis (PCA) System (2002)

For the experimental investigation of the transfer of mass concentrations in shallow turbulent flows an time/cost efficient and easy-to-use measuring technique will be presented. The Planar Concentration Analysis (PCA) technique allows to evaluate the depth-averaged concentration of a soluble conservative tracer, namely food coloring. Since PCA is based on video image analysis, the spatial and temporal resolution is high, depending on the optical components and on the digitalisation and storage capacity. Details will be given to the algorithm for the conversion of light intensity to concentration, which also accounts for the non-linear relation. This extension significantly increases the measurement range for mass concentrations. Finally the PCA system will be applied to the spreading of a tracer plume for a continuous point-source in a shallow turbulent laterally unbounded flow.
