USB/IP : universal serial bus extension over IP network (2007)

USB/IP: Universal Serial Bus Extension over IP Network (IP-uSB) () In the ideal goal of distributed system technologleS, uSerS Obtain optlmized computlng enVironments dynamically-composed of distributed hardware resources over networks on demand and seamlessly A remote device technology lS One Ofthe essential keys for this goal, which enables a system to be reconfigurable and adaptable about its device usages for various conditions and purposes.A lot of remote device teclmologleS have been studied for long years.However, there stil1 1acks afully general and interoperable device access mechanism over IP networks, though considered necessary to tackle the increaslng diverslty Of devices and computers.Most remote device teclmologleS in operatlng SyStemS involve operatlng-SyStem-SPeCific abstractions in their mechanisms.This dissertation proposes a network extension of USB, a multipurpose peripheral interface, via host controller virtualization in operatlng SyStemS.It decouples device requests and messaglng from bus controls, and therefore enables remote access requests and semantics to become the same as physically-attached local devices; these mechanisms are independent of operatlng SyStemS and specific to their peripheral bus models.It conduces to transparent access to various types ofremote devices in the same manner as local devices, with interoperability among different operatlng SyStemS.However, since its peripheral interface is not intended to be extended over networks, this research addresses inevitable semantics differences and problems raised from its peripheral bus model.It clarifleS feasibility and restrictions of the network extension, as well as suggestions to the bus models and implementations.

Abstract
Kinetics of Refolding of Completely Reduced Human‐Serum Albumin (1977)

The kinetics of refolding of completely reduced human serum albumin has been studied by various methods including immunological techniques. The decrease in thiol content is very rapid in the beginning of the reoxidation process and rather slow in the later stages. Polyacrylamide gel electrophoresis studies show that, in the earlier stages of refolding, the main part of the albumin is present as various oligomers and that a slow conversion to monomer occurs as reoxidation proceeds. Rocket immunoelectrophoresis shows that the completely reduced protein is devoid of native albumin antigenic determinants but that a rapid regain of immunoprecipitability is obtained upon reoxidation. A new 'consumption' rocket immunoelectrophoretic method has been used to estimate the total regain of antigenicity. The data obtained indicate that there is a preferential rapid folding to native structure in certain parts of the molecule but that areas with wrong or incomplete foldings exist a considerable time after the inital refolding period.
A framework for reconfigurable computing: task scheduling and context management (2001)

Dynamically reconfigurable architectures are emerging as a viable design alternative to implement a wide range of computationally intensive applications. At the same time, an urgent necessity has arisen for support tool development to automate the design process and achieve optimal exploitation of the architectural features of the system. Task scheduling and context (configuration) management become very critical issues in achieving the high performance that digital signal processing (DSP) and multimedia applications demand. This article proposes a strategy to automate the design process which considers all possible optimizations that can be carried out at compilation time, regarding context and data transfers. This strategy is general in nature and could be applied to different reconfigurable systems. We also discuss the key aspects of the scheduling problem in a reconfigurable architecture such as MorphoSys. In particular, we focus on a task scheduling methodology for DSP and multimedia applications, as well as the context management and scheduling optimizations.
Optical detection up to 2.5 Gbit/s with a standard high-speed self-aligned silicon bipolar transistor (1988)

The photoresponse of the base-collector (BC) diode of a standard high-speed self-aligned silicon bipolar transistor was investigated, showing optical detection capabilities up to 2.5 Gbit/s.
UV photoemission from metal cathodes for picosecond power switches (1989)

Results are reported of photoemission studies using laser pulses of 10 ps duration and 4.66 eV photon energy on metal cathodes. These included thin wires, flat surfaces and an yttrium cathode with a grainy surface. The measurements of current density and quantum efficiency under low and high surface fields indicate that field assisted efficiencies exceeding 0.1% and current densities exceeding 10/sup 5/ A/cm/sup 2/ are obtainable. The results are compared to the requirements of switch power applications. 24 refs., 13 figs., 1 tab.
Low noise preamplifier design for nerve cuff electrode recording systems (2003)

This paper discusses certain crucial issues involved in the design of a preamplifier for an implantable neural prosthesis. The preamplifier has a nominal gain of 100, a bandwidth of 15kHz and is required to combine very low noise with low power consumption. In particular, due to the low frequencies involved, 1/f noise assumes great significance. We consider three possible architectures for the input stage of the preamplifier: (a) BiCMOS and CMOS in (b) weak and (c) strong inversion. We demonstrate that although the CMOS amplifiers can approach the performance of the BiCMOS circuit, this is only possible at the cost of greater power consumption and enormously increased circuit area. Against these arguments must be set the greater cost of a BiCMOS process.
Full-length LGR5-positive cells have chemoresistant characteristics in colorectal cancer (2016)

The function of LGR5FL-positive cells had low cell proliferative ability compared with the cells, which expressed splice variants of LGR5 and remained after chemotherapy. Designing therapeutic strategies that target LGR5FL-positive cells seems to be important in colorectal cancer.
Phosphoinositide metabolism and Ca2+ oscillation. (1998)

The main pathways of hydrolysis and synthesis of phosphoinositides, metabolism of inositol phosphates and their role in animal and human cells are reviewed. Mechanisms of regulation of phospholipase C and other key enzymes of phosphoinositide metabolism by hormones and growth factors are discussed. The mechanisms of regulation of metabolism and cellular activity by second messengers formed during activation of phosphoinositide hydrolysis are considered. Special attention is given to the regulation of cytoplasmic Ca2+ level by inositol phosphates. The review summarizes data on formation and possible biological role of inositol phosphates and phosphoinositides containing phosphate at position 3. The role of phosphoinositides in the interaction of cellular membranes with proteins of the cytoskeleton is considered.
Characterization of Epstein‐Barr Virus (EBV)‐Positive NK Cells Isolated from Hydroa Vacciniforme‐Like Eruptions (2003)

Recently, the involvement of Epstein-Barr virus (EBV) in hydroa vacciniforme (HV)-like eruptions has been suggested. To elucidate the role of EBV in this disease, we isolated EBV-infected cell clones from peripheral blood mononuclear cells (PBMC) and the skin lesions of a patient with HV-like eruptions; cells isolated from PBMC were designated SNK-12, and those from the eruption SNK-11. Both cells expressed CD16, CD56, and HLA-DR and had germline configurations of the T-cell receptor and the immunoglobulin genes, indicating that the cell clones were of NK cell lineage. The analysis of EBV terminal repeats indicated that the cells were monoclonal, had identical clonality, and originated from EBV-positive cells in the PBMC and eruption. Both clones expressed EBNA-1, but not EBNA-2. Although LMP-1 was weakly detected in SNK-11, no LMP-1 was detected in SNK-12. Interestingly, EBV-infected cells required less IL-2 for in vitro growth in the later phase of this disease and this appeared to correlate with the expression of LMP-1, suggesting that the proliferative capacity of the EBV-positive NK cells increased during the time course of the disease, and LMP-1 expression might be responsible for that. This is the first report of the isolation of EBV-infected cells from the skin lesions of HV-like eruptions and strongly suggests that the HV-like eruption in the patient was caused by clonal NK cells with latent EBV infection.
Gap junctions between human corpus cavernosum smooth muscle cells: gating properties and unitary conductance (1993)

We previously showed that corpus cavernosum smooth muscle cells are connected via gap junctions in situ and in culture and that a major protein component of these gap junctions is connexin43. To characterize the physiological properties of the gap junctions between corpus cavernosum smooth muscle cells, we now demonstrate that the cells are dye and electrically coupled and describe some of the gating properties of these gap junctional channels at macroscopic and single-channel levels. Junctional conductance (gj) between corporal smooth muscle cells was moderately voltage sensitive; was reduced rapidly, reversibly, and completely by halothane; and was increased by treatment with a tumor-promoting phorbol ester [12-O-tetradecanoylphorbol-13-acetate (TPA)] and decreased by isoproterenol. Histograms of unitary junctional currents revealed multiple conductance peaks with events of approximately 90 pS being the most abundant. TPA and phenylephrine produced large increases in relative frequencies of the smaller events, whereas isoproterenol and 8-bromoadenosine 3',5'-cyclic monophosphate (8-BrcAMP) slightly increased the relative frequencies of the larger events. None of the tested drugs substantially affected the steady-state voltage dependence of gj. These second messenger systems also affected expression of connexin43 by corpus cavernosum smooth muscle cells, as judged by immunoblots. At 6 h of treatment, both TPA- and 8-BrcAMP-treated cultures showed markedly elevated levels of connexin43, whereas at 24 h, the level of connexin43 in TPA-treated cultures had returned to control levels. Together, these data indicate that second messenger molecules involved in penile erection produce changes in gap junction expression and function; it is plausible that these changes could be physiologically relevant in altering and propagating changes in vasomotor tone.
Protective immunization with plasmid DNA containing the outer surface lipoprotein A gene of <i>Borrelia burgdorferi</i> is independent of an eukaryotic promoter (1996)

Plasmid DNA encoding the outer surface lipoprotein A (OspA) of Borrelia burgdorferi under the control of either strong eukaryotic/viral or its own bacterial promoter was injected intramuscularly (m. tibialis anterior) or intradermally into BALB/c and AKR/N mice. OspA-specific antibodies and OspA-reactive T helper 1 cells (Th1) were induced only with those plasmids containing the ospA structural gene including its own regulatory control region immediately upstream. In the absence of the ospA promoter, no or only marginal immune responses to OspA were obtained, even when strong eukaryotic promoter/enhancer elements were present. Together with the finding that the ospA promoter is active in a mouse B-lymphoma line, the data suggest that spirochetes are able to express at least part of their genes in the mammalian environment. Mice previously vaccinated with the relevant ospA plasmid DNA were protected against subsequent experimental challenge with a virulent strain of B. burgdorferi, as measured by the appearance of antibodies to a prominent protective epitope (LA-2) and the failure to re-isolate spirochetes from ear biopsies. In addition, C.B-17 severe-combined immunodeficient mice could be protected against infection by passive transfer of immune sera from ospA plasmid DNA-inoculated normal mice. Protective LA-2-related antibody titers obtained after repeated immunization persisted for 200 days and longer. This simple procedure of immunization using plasmid DNA consisting of a prokaryotic gene under the control of its own promoter holds great promise for the development of alternative subunit vaccines against bacterial infections, including Lyme disease. In addition, the availability of this novel prokaryotic promoter element now allows the study of the basis for the differential expression of bacterial genes in prokaryotic and eukaryotic environments.
Treatment of X-linked adrenoleukodystrophy with Lorenzo's oil (1999)

There is no single diabetic neuropathy. A wide variety of syndromes involving the peripheral nerves may be encountered in patients with diabetes mellitus, implying a correspondingly diverse range of underlying causative mechanisms. The classification of the diabetic neuropathies is not yet finalised and has required successive modifications in the light of accumulating knowledge. The scheme favoured by myself is given in the table. This broadly categorises the manifestations into (1) rapidly reversible phenomena, (2) generalised polyneuropathies, (3) focal and multifocal neuropathies, and (4) superimposed chronic inflammatory demyelinating polyneuropathy.

Effect of experimental suprascapular nerve block on active glenohumeral translations in vivo (2006)

Static superior shoulder instability is associated with long-standing rotator cuff tears. Factors or mechanisms which can prevent superior migration of the humeral head, and therefore allow preservation or restoration of shoulder function despite nonanatomical cuff repair, are poorly understood. The question has therefore arisen, whether centering of the humeral head was the result of active shoulder muscle function. It was the goal of this experimental investigation to (1) determine the pattern of glenohumeral translations during active shoulder abduction measured by open-magnetic resonance imaging (MRI) techniques, and to (2) determine the influence of experimental paralysis of the infra- and supraspinatus muscles on these translations. In contrast to prior experimental investigations, the humeral head remained always centered in the glenoid fossa during active abduction. No superior migration of the humeral head could be provoked with experimental paralysis of the supra- and/or infraspinatus muscles. The hypothesis that static or dynamic superior humeral head displacement is prevented by active-supra- and/or infraspinatus muscle function must therefore be rejected, for the shoulder with a structurally intact muscle-tendon-bone unit.
Preservation of the cardiac function in infarcted rat hearts by the transplantation of adipose-derived stem cells with injectable fibrin scaffolds (2010)

Cell-based therapy can improve cardiac function but is limited by the low cell retention and survival within ischemic tissues. Injectable cardiac tissue engineering aims to support cell-based therapies and enhance their efficacy for cardiac diseases. So far, no research has been devoted to studying the usefulness of the combination of fibrin glue (as scaffold) and adipose-derived stem cells (ADSCs) to treat myocardial infarction. In our study, the rat ADSCs were isolated from subcutaneous adipose tissues. The surface phenotype of these cells was analyzed by flow cytometry. The fibrin glue was then co-injected with ADSCs into the left ventricular wall of rat infarction models. The structure and functional consequences of transplantation were determined by detailed histological analysis and echocardiography. Most cultured ADSCs expressed CD105 and CD90, and were negative for CD34 and CD45. After injection, both the 24-h cell retention and four-week graft size were significantly higher and larger in the Fibrin + ADSCs group than those of the ADSCs group alone (P < 0.01). The heart function improved significantly in the Fibrin + ADSCs group compared with that of the ADSCs group four weeks after transplantation (P < 0.01). In addition, the arteriole densities within the infarcted area improved significantly in the Fibrin + ADSCs group compared with those in the ADSCs group four weeks after transplantation (P < 0.01). In conclusion, the ADSCs with the fibrin glue has the therapeutic potential to improve the function of infarcted hearts. The method of in situ injectable tissue engineering combining fibrin glue with ADSCs is promising clinically.
Case 15-1970 (1970)

Presentation of Case First admission. A thirty-eight-year-old man was admitted to the hospital because of uremia.At the age of fourteen years he had been studied at another hospital because of "kidney trouble"; an intravenous pyelographic study revealed dilatation of the left collecting system and a calyceal filling defect, and a retrograde pyelographic study demonstrated bilateral ureteral angulations. Subsequently, he failed the Armed Services induction examination because of proteinuria. Eighteen months before entry there was the onset of fatigue, malaise and joint swelling, interpreted by a physician as "gouty arthritis." One year later weakness, pallor, dyspnea and ankle edema . . .
Characterization of a novel arginine/serine-rich splicing factor in Arabidopsis. (1996)

Many splicing factors in vertebrate nuclei belong to a class of evolutionarily conserved proteins containing arginine/serine (RS) or serine/arginine (SR) domains. Previously, we demonstrated the existence of SR splicing factors in plants. In this article, we report on a novel member of this splicing factor family from Arabidopsis designated atRSp31. It has one N-terminal RNA recognition motif and a C-terminal RS domain highly enriched in arginines. The RNA recognition motif shows significant homology to all animal SR proteins identified to date, but the intermediate region does not show any homology to any other known protein. Subsequently, we characterized two cDNAs from Arabidopsis that are highly homologous to atRSp31 (designated atRSp35 and atRSp41). Their deduced amino acid sequences indicate that these proteins constitute a new family of RS domain splicing factors. Purified recombinant atRSp31 is able to restore splicing in SR protein-deficient human S100 extracts. This indicates that atRSp31 is a true plant splicing factor and plays a crucial role in splicing, similar to that of other RS splicing factors. All of the three genes are differentially expressed in a tissue-specific manner. The isolation of this new plant splicing factor family enlarges the essential group of RS domain splicing factors. Furthermore, because no animal equivalent to this protein family has been identified to date, our results suggest that these proteins play key roles in constitutive and alternative splicing in plants.
Compact Semiconductor Tapers for Deep-to-Shallow Etch Transitions (2007)

Double-etched taper devices for application as mode converters between shallow and deep-etched waveguides are presented with particular attention paid to the derivation of the taper profile. Finite-difference time-domain simulations of the devices are carried out and compared with fabricated devices along with a transfer matrix method representation that confirms the extraction of values for reflectivity from the transmission spectra of the devices. Tapers of sub-100-mum lengths are shown to exhibit losses of <0.5 dB and reflectivities of <0.05%.
Low-threshold, self-frequency-stabilized AgGaS_2 continuous-wave subharmonic optical parametric oscillator (1998)

We report the demonstration of a cw AgGaS(2) optical parametric oscillator (OPO). The subharmonic (3omega ? 2omega + omega) OPO is configured as a doubly resonant oscillator with weak pump enhancement. The temperature-tuned, noncritically phase-matched crystal is pumped by a diode laser at lambda(p) approximately 845 nm . Oscillation at lambda(s) approximately 1267 nm and lambda(i) approximately 2535 nm is observed at an input threshold power of 60 mW. Crystal thermal loading induces a robust passive self-frequency stabilization of any single-axial-mode pair to the OPO cavity resonance. The conversion efficiency is limited by thermal effects to 2% for a 200-mW pump input.
<i>In Vivo</i> Dynamic MRI Tracking of Rat T‐Cells Labeled with Superparamagnetic Iron‐Oxide Particles (1995)

Dynamic MRI tracking of rat T-cells in vivo is performed in rat testicles after labeling isolated rat T-cells in vitro with superparamagnetic dextran-coated iron-oxide particles, BMS180549. Tissue inflammation induced by the local injection of the calcium ionophore, A23187, is used to attract labeled T-cells. Gradient-echo MR images of rat testicles show a statistically significant decrease (4%) of the signal intensity in areas of injection of A23187 as early as 30 min after intravenous infusion of 2 x 10(8) labeled T-cells. The signal change reaches its maximum (6-7% decrease) at about 60-120 min after cell infusion. T2-mapping also shows a decrease of T2 in the areas with A23187. Image quantitation, which includes a chemical-shift effect, significantly enhances the sensitivity for detection of superparamagnetically labeled T-cells. Localization of labeled T-cells in rat testicles has been verified by fluorescence microscopy studies of T-cells co-labeled with a lipophilic fluorescent carbocyanine dye, 1,1-dioctadecyl-3,3,3',3'-tetramethyl-lindocarbocyanine perchlorate. These results represent the first successful demonstration of dynamic tracking of specific cells in vivo using MRI.
