Dietary Calcium Induces Regression of Left Ventricular Hypertrophy in Hypertensive Non - Insulin-dependent Diabetic Blacks (1990)

Recent data from this laboratory indicate that dietary calcium supplementation causes reduced intracellular calcium in type II diabetic hypertensives. Consequently, we have assessed the effects of calcium supplementation on forearm blood flow (FBF) and vascular resistance (FVR) and left ventricular mass (LVM) in seven type II diabetic hypertensive black men with left ventricular hypertrophy (LVH) maintained off antihypertensive treatment for four weeks and then supplemented with 600 mg calcium per day for three months. A comparable group of black diabetic hypertensive patients treated with atenolol (50 mg) served as controls. LVM was determined by M-mode echocardiography and FBF and FVR by electrical impedance plethysmography at the end of the four week baseline and the 12 week supplementation periods. Calcium supplementation resulted in a decrease (P less than .05) in mean arterial pressure (from 121 +/- 4 to 114 +/- 3 mm Hg) which was accompanied by an 18% increase in FBF and a 20% reduction in FVR (P less than .05). LVM decreased from 289 +/- 22 at baseline to 240 +/- 22 g at the end of the supplementation period (P less than .02) and there was a significant correlation between changes in FBF and LVM (r = 0.82). Left ventricular end diastolic dimension decreased by 11% (P less than .05). These data indicate that calcium supplementation sufficient to normalize dietary calcium in black hypertensive diabetic men significantly reduces vascular resistance and causes partial regression of LVH.
Electrostatic Beneficiation of Lunar Simulant (2006)

Electrostatic beneficiation of lunar regolith is a method allowing refinement of specific minerals in the material for processing on the moon. The use of tribocharging the regolith prior to separation was investigated on the lunar simulant MLS-I by passing the dust through static mixers constructed from different materials; aluminum, copper, stainless steel, and polytetrafluoroethylene (PTFE). The amount of charge acquired by the simulant was dependent upon the difference in the work function of the dust and the charging material. XPS and SEM were used to characterize the simulant after it was sieved into five size fractions (&gt; 100 pm, 75-100 pm, 50- 75 pm, 50-25 pm, and &lt; 25 pm), where very little difference in surface composition was observed between the sizes. Samples of the smallest (&lt; 25 pm) and largest (&gt; 100 pm) size fractions were beneficiated through a charge separator using the aluminum (charged the simulant negatively) and PTFE (charged positively) mixers. The mass fractions of the separated simulant revealed that for the larger particle size, significant unipolar charging was observed for both mixers, whereas for the smaller particle sizes, more bipolar charging was observed, probably due to the finer simulant adhering to the inside of the mixers shielding the dust from the charging material. Subsequent XPS analysis of the beneficiated fractions showed the larger particle size fraction having some species differentiation, but very little difference for the smaller.size. Although MLS-1 was made to have similar chemistry to actual lunar dust, its mineralogy is quite different. On-going experiments are using NASA JSC-1 lunar simulant. A vacuum chamber has been constructed, and future experiments are planned in a simulated lunar environment.

The spatial size of ion events measured far upstream of the Earth's bow shock by ACE/ULEIS and WIND/STEP (2000)

Using ACE/ULEIS and WIND/STEP &gt;40 keV ion measurements, we have calculated the probability of simultaneously observing ion events upstream of the earth's bow shock as a function of the lateral separation (in Y GSE and Z GSE ) of the two spacecraft, thus providing a quantitative measurement of the spatial size of upstream ion events. Our survey consisted of 202 days in 1997 and 1998 when the ACE and WIND spacecraft were near the first Lagrangian point, approximately 200 R E upstream of the earth. We find that for lateral separations of up to 70 R E , the coincidence rate of events at the two spacecraft remains high and conclude that the source region of the upstream ions is large when compared to the size of the bow shock.
A Disposable Hypoxanthine Sensor Based on a Micro Oxygen Electrode (1989)

Abstract A disposable type micro enzyme sensor was constructed using a Clark-type micro oxygen electrode and immobilized xanthine oxidase (EC 1.1.3.22) for the assay of hypoxanthine which is an important marker for the fish freshness estimation. The sensor showed a good response to hypoxanthine and allowed the determination of hypoxanthine in the concentration range between 6.7 – 180 μM.
Robust and Scalable Integrated Routing in MANETs Using Context-Aware Ordered Meshes (2010)

A new context-aware routing framework for multicast and unicast routing in mobile ad hoc networks is introduced. This framework, which is called CAROM (Context-Aware Routing over Ordered Meshes), uses regions of interest to identify connected components of the network that span sources and destinations of interest to restrict signaling to occur mostly within these regions. Context information is used to compute routing meshes composed of shortest-paths located inside of regions of interest. Experimental results based on extensive simulations show that CAROM attains similar or better data delivery and end-to-end delays than traditional unicast and multicast routing schemes for MANETs (AODV, OLSR, ODMRP), and that CAROM incurs only a fraction of the signaling overhead of traditional routing schemes.
Cervicocephalic kinesthetic sensibility in patients with whiplash injury (2019)

This study investigated cervicocephalic kinesthetic sensibility in patients with whiplash injury and the effects of a rehabilitation programme. Fourteen patients with a whiplash injury and 34 healthy subjects participated in this study. The ability to appreciate both movement and the position of the head with respect to the trunk was investigated. Active head repositioning was significantly less precise in the whiplash subjects compared to the control group. Repositioning was more precise in whiplash subjects after the 5-week rehabilitation programme. There was no correlation between error of repositioning in patients and pain intensity. It is probable that cervicocephalic kinesthesia is linked to sensory information from the extensive muscular and articular proprioceptive system. A flexion-extension injury to the neck may result in dysfunction of this system.
Latent Mouse Encephalomyelitis (1947)

Summary These observations are concerned with the chance occurrence of latent mouse encephalomyelitis, either the paralytic TO or encephalitic FA type, in normal stock Swiss mice. In the course of experiments utilizing about 40,000 mice purchased chiefly from two animal dealers, the TO type of encephalomyelitis was encountered spontaneously in 4 instances, and following non-specific inoculations in 3 instances. The FA virus was found to be the cause of encephalomyelitis occurring in one instance spontaneously, and in 7 instances following intracerebral inoculation of non-infectious material or of murine-adapted strains of human poliomyelitis virus. In the latter instances, the inoculated murine-adapted virus and the contaminating FA strain were separated into pure lines of each strain. The contaminated murine-adapted human strains were freed of FA virus by treatment with FA hyper-immune serum or by passage through the monkey, a host which is not susceptible to the FA virus. FA virus was readily obtained from the mixture of strains by serial passage of brains of mice showing only encephalitic signs or by passage through chick embryos. The virus strains were identified by complement fixation and/or virus neutralization tests as well as by their host spectrum and “clinical” signs. There was no evidence that the interference phenomenon prevented the simultaneous passage of the Lansing and the FA strains through several serial transfers in mice.

5G Component Carrier Management Evaluation by Means of System Level Simulations (2019)

This work presents essential aspects of 5G system level simulator for enabling advanced component validations and optimizations. System level simulations in the 5G era, consider demanding use cases with high load and very limited latency in order to cover services such as enhanced mobile broadband (eMBB), massive machine-type communications (mMTC) and ultra-reliable low-latency communications (URLLC). As such, appropriate configuration, environment and network models need to be defined in order to proceed to performance evaluation. The system-level simulation platform is a discrete event simulation environment for the simulation of heterogeneous networks which is extended with new features to support the new functionalities of 5G. To show the potential of this simulation tool, in this work, a framework for multi-connectivity management has been integrated and assessed in a load-imbalanced scenario. Simulation results show how a proper assignment of component carriers (CCs) in this situation allows increasing the users' throughput by up to a 60% when compared to a simple received power scheme for link management.
Interactive faceted query suggestion for exploratory search: Whole‐session effectiveness and interaction engagement (2019)

Abstract The outcome of exploratory information retrieval is not only dependent on the effectiveness of individual responses to a set of queries, but also on relevant information retrieved during the entire exploratory search session. We study the effect of search assistance, operationalized as an interactive faceted query suggestion, for both whole‐session effectiveness and engagement through interactive faceted query suggestion. A user experiment is reported, where users performed exploratory search tasks, comparing interactive faceted query suggestion and a control condition with only conventional typed‐query interaction. Data comprised of interaction and search logs show that the availability of interactive faceted query suggestion substantially improves whole‐session effectiveness by increasing recall without sacrificing precision. The increased engagement with interactive faceted query suggestion is targeted to direct situated navigation around the initial query scope, but is not found to improve individual queries on average. The results imply that research in exploratory search should focus on measuring and designing tools that engage users with directed situated navigation support for improving whole‐session performance.
Polyphasic taxonomy of the genus Shewanella and description of Shewanella oneidensis sp. nov. (1999)

The genus Shewanella has been studied since 1931 with regard to a variety of topics of relevance to both applied and environmental microbiology. Recent years have seen the introduction of a large number of new Shewanella-like isolates, necessitating a coordinated review of the genus. In this work, the phylogenetic relationships among known shewanellae were examined using a battery of morphological, physiological, molecular and chemotaxonomic characterizations. This polyphasic taxonomy takes into account all available phenotypic and genotypic data and integrates them into a consensus classification. Based on information generated from this study and obtained from the literature, a scheme for the identification of Shewanella species has been compiled. Key phenotypic characteristics were sulfur reduction and halophilicity. Fatty acid and quinone profiling were used to impart an additional layer of information. Molecular characterizations employing small-subunit 16S rDNA sequences were at the limits of resolution for the differentiation of species in some cases. As a result, DNA-DNA hybridization and sequence analyses of a more rapidly evolving molecule (gyrB gene) were performed. Species-specific PCR probes were designed for the gyrB gene and used for the rapid screening of closely related strains. With this polyphasic approach, in addition to the ten described Shewanella species, two new species, Shewanella oneidensis and 'Shewanella pealeana', were recognized; Shewanella oneidensis sp. nov. is described here for the first time.
The primary structure of rat liver ribosomal protein L37. Homology with yeast and bacterial ribosomal proteins. (1983)

The covalent structure of the rat liver 60 S ribosomal subunit protein L37 was determined. Twenty-four tryptic peptides were purified and the sequence of each was established; they accounted for all 111 residues of L37. The sequence of the first 30 residues of L37, obtained previously by automated Edman degradation of the intact protein, provided the alignment of the first 9 tryptic peptides. Three peptides (CN1, CN2, and CN3) were produced by cleavage of protein L37 with cyanogen bromide. The sequence of CN1 (65 residues) was established from the sequence of secondary peptides resulting from cleavage with trypsin and chymotrypsin. The sequence of CN1 in turn served to order tryptic peptides 1 through 14. The sequence of CN2 (15 residues) was determined entirely by a micromanual procedure and allowed the alignment of tryptic peptides 14 through 18. The sequence of the NH2-terminal 28 amino acids of CN3 (31 residues) was determined; in addition the complete sequences of the secondary tryptic and chymotryptic peptides were done. The sequence of CN3 provided the order of tryptic peptides 18 through 24. Thus the sequence of the three cyanogen bromide peptides also accounted for the 111 residues of protein L37. The carboxyl-terminal amino acids were identified after carboxypeptidase A treatment. There is a disulfide bridge between half-cystinyl residues at positions 40 and 69. Rat liver ribosomal protein L37 is homologous with yeast YP55 and with Escherichia coli L34. Moreover, there is a segment of 17 residues in rat L37 that occurs, albeit with modifications, in yeast YP55 and in E. coli S4, L20, and L34.
Lens Implants in Cataract Surgery (1976)

To the Editor.— Implantable lenses have been in use since 1949. The early lenses were disappointing because of complications caused by material and design problems. The skepticism that resulted from experience with these early lens devices is no longer justified. Advances made in intraocular lens technology in the past few years have accounted for a dramatic decrease in complications and restoration of vision as has never been possible with glasses or contact lenses. Criticism of the currently used intraocular iris- or capsule-mounted lens devices is out of date and applicable only to the earlier, mechanically primitive implants. It is analagous to complaining of the limitation of computers because of their weight, size, heat production, and energy consumption. This may have applied in 1950, but today, a computer of the same capacity—and better—can literally be held in the hand. We are now working with third generation lenses—past the Ridley lens and
Validation study of the Japanese version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire‐Testicular Cancer 26 for patients with testicular cancer (2020)

The psychometric properties of the Japanese version are equivalent to the properties of the original European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Testicular Cancer 26. The Japanese version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Testicular Cancer 26 questionnaire is a useful tool to assess the health-related quality of life of testicular cancer patients.
Inter-operator resource sharing in 4G LTE cellularnetworks (2011)

The dramatic increase in wireless data traffic challenges cellular network operators to increase wireless access and system capacity, and to reduce costs of deploying and operating the network infrastructure. In light of the cost and complexity of large scale networks as well as the absence of new spectrum, the paradigm of resource sharing is explored to address these challenges. In this research, we examine three cellular resource sharing approaches: Capacity, Spectrum and Infrastructure Hardware and propose various sharing options in the context of 4G LTE. We propose a unified coordinated sharing process and architecture by introducing a new network Sharing Entity (SE). The SE enables dynamic creation, modification and termination of resource sharing agreements among operator that can be conditional or restrictive in time, space and other dimensions. We present the required technologies in two cases: (1) Traditional infrastructure for capacity and spectrum sharing options wherein the networks of operators participating in sharing are physically independent infrastructures. (2) Virtualized infrastructure for hardware sharing option wherein a single physical infrastructure virtualizes infrastructures of participating operators. We model two geographically overlapped LTE cellular networks, operated by two operators, with the proposed sharing architecture and process. We evaluate sharing options based on multiple performance metrics and cost saving estimates under light, moderate and heavy loading scenarios via simulations in collocated and non-collected deployment topologies.
A Novel Colorimetric Immunoassay Utilizing the Peroxidase Mimicking Activity of Magnetic Nanoparticles (2013)

A simple colorimetric immunoassay system, based on the peroxidase mimicking activity of Fe3O4 magnetic nanoparticles (MNPs), has been developed to detect clinically important antigenic molecules. MNPs with ca. 10 nm in diameter were synthesized and conjugated with specific antibodies against target molecules, such as rotaviruses and breast cancer cells. Conjugation of the MNPs with antibodies (MNP-Abs) enabled specific recognition of the corresponding target antigenic molecules through the generation of color signals arising from the colorimetric reaction between the selected peroxidase substrate, 3,3',5,5'-tetramethylbenzidine (TMB) and H2O2. Based on the MNP-promoted colorimetric reaction, the target molecules were detected and quantified by measuring absorbance intensities corresponding to the oxidized form of TMB. Owing to the higher stabilities and economic feasibilities of MNPs as compared to horseradish peroxidase (HRP), the new colorimetric system employing MNP-Abs has the potential of serving as a potent immunoassay that should substitute for conventional HRP-based immunoassays. The strategy employed to develop the new methodology has the potential of being extended to the construction of simple diagnostic systems for a variety of biomolecules related to human cancers and infectious diseases, particularly in the realm of point-of-care applications.
Hemmung der Restenose nach PTA peripherer Arterien von Schweinen durch Paclitaxel-beschichtete Ballonkatheter (2004)

Ziele: Paclitaxel hemmt die Restenosebildung durch Intimahyperplasie nach Stent-PTA. Die Applikation erfolgte bisher durch langsame Freisetzung des Paclitaxels aus beschichteten Stents. Wir konnten kürzlich am Schweinemodell zeigen, dass auch die einmalige i.a. Injektion eines Paclitaxel-Kontrastmittelgemisches die Intimahyperplasie dauerhaft hemmt. Ziel dieser Studie war zu untersuchen, ob die Verwendung Paclitaxel-beschichteter Ballonkatheter die Intimahyperplasie nach Stent-PTA peripherer Arterien hemmen kann. Methode: 27 ballonexpandierbare Stents (Durchmesser 4mm, Länge 20mm) wurden in periphere Arterien von Schweinen implantiert. Die Dilatation führte zu einer 20%igen Überdehnung des Gefäßes zur Restenoseinduktion. Der Stent diente zur Markierung des dilatierten Gefäßabschnittes. In 10 Arterien erfolgte die Dilatation mit einem konventionellen unbeschichteten Ballon (Kontrollgruppe), in 17 Fällen kam ein Paclitaxel-beschichteter Ballon zum Einsatz (Behandlungsgruppe). Nach 5 Wochen erfolgte eine Reangiographie mit quantitativer Auswertung folgender Parameter: Referenzdurchmesser außerhalb des Stents, minimaler Lumendurchmesser im Stent, relative Stenose (durchmesserbezogen). Ergebnis: Die angiographischen Befunde zum Zeitpunkt der Stentimplantation waren für beide Gruppen gleich. In der Reangiographie war der minimale Lumendurchmesser im Stent in der Behandlungsgruppe signifikant größer als in der Kontrollgruppe (3.1±0.5mm versus 2.4±0.8mm; p=0.028). Die relative Stenose nahm deutlich von 38±20% (Kontrollgruppe) auf 15±19% (Behandlungsgruppe) ab (p<0.05). Schlussfolgerung: Die Verwendung Paclitaxel-beschichteter Ballons bei der Stent-PTA peripherer Arterien hemmt die Restenosebildung am Schweinemodell.
On large-scale reliable multicast protocols (1998)

In this paper we examine the impact of widely spread multicast groups on the performance of reliable multicast protocols. In a brief analysis we show that transmission cost for reliable multicast increases rapidly with the distance between retransmitting and receiving hosts. Since this distance is not considered by existing protocols, which are based on retransmissions originated at the sender or receiver, the performance often is rather poor and a new error recovery concept has to be developed. Our approach. the Scalable and Reliable Multicast Transport protocol (SRMT), allows retransmissions by extended multicast routers to limit the path length for error recovery. Moreover, the retransmission load can be further reduced by an XOR combination of packets. SRMT is defined as an overlay network model and therefore can be applied to any existing multicast protocol.
Fischer−Tropsch Wax Hydrogenation over a Sulfided Nickel-Molybdenum Catalyst (2007)

The hydrotreatment of paraffinic Fischer−Tropsch wax fractions with a high congealing point (98 °C) was investigated in a flow reactor in the presence of a commercial sulfided NiMo/Al2O3 catalyst at temperatures ranging from 255 to 330 °C, at pressures of 30 and 60 bar, and at different hydrogen to liquid feed ratios. Three wax fractions of similar composition, but of different saybolt color, were used as feed which required different conditions to obtain a product with acceptable properties. In all cases, a pressure of 60 bar produced the best results and saybolt colors of better than +24 could be obtained at 330 °C from a feedstock with a color of −41 saybolt units. Minimal isomerization and hydrogenolysis of the wax was observed in the temperature range investigated.
