Purification and characterization of an immunologically distinct delta-hemolysin from a canine strain of Staphylococcus aureus (1978)

Culture supernatants of 26 strains of Staphylococcus aureus possessing delta-hemolytic activity have been tested by immunodiffusion against a serum raised against purified delta-hemolysin from S. aureus CN 4108 (Newman D2). Supernatants from 14 strains of canine origin gave a reaction of partial identity with delta-hemolysin from CN 4108, whereas supernatants from all other strains had full identity. Delta hemolysin from one of these canine strains, CN 7450, was purified by ammonium sulfate fractionation and precipitation at pH 4.5. The physical, chemical, and biological properties of this toxin were compared with those of delta-hemolysin from CN 4108. Differences in molecular weight (as judged by Sepharose 6B chromatography), isoelectric point, and amino acid composition were found. Both toxins caused dermonecrosis in rabbits, lysed erythrocytes from several different species, and were inhibited by normal sera and phospholipids. Unlike delta-hemolysin from CN 4108, the hemolytic activity of delta-hemolysin from CN 7450 was found to be dependent on the incubation temperature over the range of 25 to 37 degrees C. Immunodiffusion results obtained with antisera raised against purified delta-hemolysin from CN 7450 indicated that delta-hemolysins from the canine strains were probably identical and confirmed that these differ immunologically from delta-hemolysin from CN 4108.
How to set up a low cost tele-ultrasound capable videoconferencing system with wide applicability (2012)

RTUS examinations can educate and guide point of care clinical providers to enhance their use of ultrasound. The scope of the examinations conducted is limited only by the time available and the criticality of the subject being examined. As internet connectivity will only improve worldwide, future developments need to focus on the human factors to optimize tele-sonographic interactions.

Evolutionary relationships and functional conservation among vertebrate Max-associated proteins: the zebra fish homolog of Mxi1. (1994)

In mammals, current evidence supports the view that Myc-responsive activities are regulated in part through an intracellular balance between levels of transcriptionally-active Myc/Max heterodimers and those of transcriptionally-inert Max/Max, Mad/Max and Mxi1/Max complexes. To gain insight into the roles of Mad and Mxi1 in cellular growth and differentiation and to fortify key structure-function relationships from an evolutionary standpoint, low stringency hybridization screens were used to identify potential homologs of these Max-associated proteins in the zebra fish genome. A single class of cDNA clones that cross-hybridized both to human mad and mxi1 probes was shown to encode a putative protein with significantly greater homology to mammalian Mxi1 than to Mad, particularly in the basic and helix-loop-helix (bHLH) regions. The high degree of structural relatedness between vertebrate Mxi1 proteins apparent in molecular modelling studies was consistent with the findings that the HLH/leucine zipper (LZ) region of zMxi1 exhibited the same profile of dimerization specificities as its mammalian counterpart in the two-hybrid system and that zmxi1 could, like human mxi1 (Lahoz et al., 1994), suppress the oncogenic potential of mouse c-myc in a mammalian cell. Finally, a comparison of steady-state zc-myc and zmxi1 mRNA levels during zebra fish embryogenesis demonstrated (i) high levels of zc-myc relative to zmxi1 mRNA during initiation of organogenesis, a period characterized by intense growth and active differentiation and (ii) rising levels of zmxi1 mRNA during progression towards the terminally differentiated state. These contrasting patterns of developmental expression together with the capacity of zmxi1 to repress myc-induced transformation support a model for the regulation, by Max-associated proteins, of Myc functions in the control of normal cell development and neoplastic growth.
Intravascular magnetic resonance imaging using a loopless catheter antenna (1997)

Recently, intravascular catheter probes have been developed to increase signal-to-noise ratio (SNR) for MR imaging of blood vessels. Miniaturization of these catheter probes without degrading their performances is very critical in imaging small vessels such as coronary arteries. Catheter coils have a loop incorporated in their structure and have limitations in physical dimensions and electromagnetic properties. The use of a loopless intravascular catheter antenna is proposed to overcome these problems. The catheter antenna is essentially a dipole, which makes a very thin diameter possible, and its electronic circuitry can be placed outside the blood vessels without performance degradation. The theoretical foundation for the design and operation of the catheter antenna is presented. Several catheter antennae, as small as 1.5 French, were constructed and tested on phantoms and rabbits with great success. The catheter antenna has a simple structure and is easy to design, implement, and operate.
160-channel FM-video transmission using optical FM/FDM and subcarrier multiplexing and an erbium doped optical fibre amplifier (1990)

A total of 16 DFB lasers with 10 GHz frequency spacing were combined to transport 160-channel FM television signals to 16 locations; each link distance was 9 km with an average power margin of 7.5 dB. The 16 optical carriers were simultaneously modulated by a composite of 10 FM-video signals. A high-finesse optical Fabry–Perot etalon with a half-intensity width of about 1.5 GHz and a free spectral range of 4 nm was used, both as an optical channel filter and as a frequency discriminator. An erbium doped fibre amplifier was used to provide a net gain of 9.2 dB.
Harnessing Location-Context for Content-based Services in Vehicular Systems (2005)

By incorporating personalised content as context, vehicular telematic services can be made more user-centric, as opposed to vehicle-centric. We develop an ontology based model to integrate both context and content in one unifying framework to facilitate the creation of such services. Scenes captured spontaneously by the user can be a useful index to his or her intent and interests. Our empirical study shows that location-con text leads to a higher precision in recognizing these captured scenes. A "tourist information" prototype based on scene recognition is built, to illustrate one such location-enhanced, user-centric service.

Demystified . . . Human endogenous retroviruses (2003)

Human endogenous retroviruses (HERVs) are a family of viruses within our genome with similarities to present day exogenous retroviruses. HERVs have been inherited by successive generations and it is possible that some have conferred biological benefits. However, several HERVs have been implicated in certain cancers and autoimmune diseases. This article demystifies these retroviruses by providing an insight into HERVs, their means of classification, and a synopsis of HERVs implicated in cancer and autoimmunity. Furthermore, the biological roles of HERVs are explored.
Market segmentation using perceived constraints (2008)

We explored the practical utility of segmenting potential visitors to Cleveland Metroparks using their constraint profiles. While a number of previous investigations have examined the performance of segmentation bases that provide insight on why people are attracted to specifi c activities (e.g., motivation, involvement, loyalty, place attachment), little is known of the merits of segmenting based on factors that inhibit access to leisure and leisure service providers. Our analysis began with exploratory factor analysis of 16 park use constraint items which identified four dimensions of constraints. These constraint items were worded to reflect potential barriers to using Cleveland Metroparks’ settings and facilities. The first dimension, Other Priorities, consisted of items that examined constraints related to time and scheduling. The second dimension, Setting Elements, was comprised of items that explored issues related to the setting that inhibited visitation and access. The third constraint dimension, Access, consisted of items touching on issues of transportation. The forth dimension, Social Factors, was comprised of items that touched on issues related to having associates and social inhibitions. Next, the four factors were then used to cluster analyze the sample into homogenous groups sharing common constraints. The cluster procedure revealed three segments. The fi rst market segment, Other Priorities, consisted of respondents who scored highest on items that examined time constraints and scheduling conflicts. The second market segment, Highly Constrained, scored relatively high on all of our constraint indicators. The last market segment, Least Constrained, scored the lowest on all of our indicators of constraints. We then examined variations among the three clusters using indicators of socio-demographics, motivation to visit Cleveland Metroparks, activity involvement, and attachment to Cleveland Metroparks’ setting and facilities. These fi ndings illustrate that constraints can be used to identify meaningful market segments who, for a variety of reasons, have difficulty accessing leisure services. Our approach illustrates that the recreating public’s experience of constraints is not uniform–different barriers confront different segments. Removing or minimizing the park use constraints germane to each segment may allow the service providers to reach out to under-served market segments or constituents. These findings further demonstrate that the experience of leisure constraints inhibits recreationists’ ability to develop deeper associations with park activities and settings.?
Andsf-based congestion control procedure in heterogeneous networks (2013)

The mobile network operators (MNOs) have considered the provision of simultaneous multiple access in heterogeneous networks. Access network discovery and selection function (ANDSF) is introduced to provide simultaneous multiple access in heterogeneous networks to users. Since a ANDSF manages the inter-system mobility and routing policy, it can mitigate congestion of a certain access networks by restricting access or IP traffic flows toward the crowded access network. However, for congestion control by ANDSF, ANDSF should enable to manage the congestion condition among heterogeneous networks. Thus, this paper proposes messages and procedures for ANDSF to collect the congestion condition among heterogeneous networks and to decide inter-system mobility and routing policy. The proposed messages and procedures can be easily implemented by extending the messages and procedures defined in the 3GPP standards.

A Hybrid Media Transmission Scheme for Wireless VoIP (2010)

In this paper, we propose an optimization framework for real-time voice transmission over wireless tandem channels prone to both bit errors and packet erasures. Utilizing a hybrid media dependent and media independent error correction scheme, our proposed framework is capable of protecting voice packets against both types of errors. For each group of frames associated with one speech spurt, the framework finds the optimal parity assignment of each voice frame according to its perceptual importance such that the quality of the received group of frames is maximized. Our performance evaluation results show that the proposed scheme outperforms a number of alternative schemes and has a low computational complexity.
Characteristics of skylight at the zenith during twilight as indicators of atmospheric turbidity 1: Degree of polarization (1980)

An extensive series of measurements of the intensity and polarization of the light from the zenith sky during periods of twilight was made at an altitude of 3400 m on the island of Hawaii during a 5-month period in 1977. This first of two papers is on the twilight polarization; the second will deal with intensity. The measurements were made in eight narrow spectral ranges between 0.32 and 0.90 microm under clear sky conditions. The data show that the degree of polarization at the zenith is a sensitive indicator of the existence of turbid layers at high levels in the atmosphere, and by monitoring the zenith skylight as a function of time during the twilight, it is possible to obtain qualitative information on both the altitude and relative density of the layers.
Semi-blind speech extraction for robot using visual information and noise statistics (2011)

In this paper, speech recognition accuracy improvement is addressed for ICA-based multichannel noise reduction in spoken-dialogue robot. First, a new permutation solving method using a probability statistics model is proposed for realistic sound mixtures consisting of point-source speech and diffuse noise. Next, to achieve high recognition accuracy for the early utterance of the target speaker, we introduce a new rapid ICA initialization method combining robot video information and a prestored initial separation filter bank. From this image information, an ICA initial filter fitted to the user's direction can be used to save the user's first utterance. The experimental results show that the proposed approaches can markedly improve the word recognition accuracy.
Reactive oxygen species, water, photons and life. (2011)

Unique properties of oxygen and of the reactions with reactive oxygen species (ROS) participation are considered, the multiple ways of ROS generation and utilization are discussed in view of evidence for the absolute necessity of ROS for the normal vital activity. Many difficulties in the realization of the real role of ROS in vital activity are caused by the attitude to them only as to chemical substances, while they should be considered in the first place as the major participants of continuous flows of highly non-linear processes in which electron excited species emerge. These processes play a significant role in energy and informational flows in all the living systems. We suggest that the mechanisms of biological action of ROS are determined by the structural patterns (frequency-amplitude patterns of electron excited states generation and their relaxation) of the processes with ROS participation taking place in the aqueous environs. Energy released in such reactions is used as an activation energy for specific biochemical processes, for the continuous "pumping" of the non-equilibrium state of inter- and intracellular structural components, while the structural patterns of ROS reactions determine biochemical and physiological rhythmic modes. Special role of water in all these phenomena is discussed. From a broader perspective the processes with ROS participation emerging in water preceded and were the necessary condition for origination and evolution of organic living forms on Earth.
Stimulation of N6,O2'-dibutyryl cyclic adenosine 3':5'-monophosphate of ectopic production of the free beta subunit of chorionic gonadotropin by a human brain tumor cell line. (1980)

Previous studies have favored a basic difference in the regulation of specialized protein production by cells derived from the usual tissue of origin (eutopic) and cancer cells derived from a tissue not normally producing the protein (ectopic). Thus N6,O2'-dibutyryl cyclic adenosine 3':5'-monophosphate was believed to stimulate only eutopic (but not ectopic) chorionic gonadotropin production, and butyrate to stimulate only ectopic (but not eutopic). However, in CBT, a human brain tumor cell line, we find that N6,O2'-dibutyryl cyclic adenosine 3':5'-monophosphate, but not butyrate, stimulated ectopic production of the beta subunit of chorionic gonadotropin. We conclude that neither butyrate nor cyclic adenosine 3':5'-monophosphate derivatives reliably discriminate ectopic from eutopic regulation.
The evolution of new generation 'single-site' Ziegler-Natta polymerization catalysts (2000)

Since the discovery of stereospecific polymerization of olefins by K. Ziegler and G. Natta in 1955, tremendous developments have occurred in the area of designing polymerization catalysts. Rapid advances in organometallic chemistry research practised both at academic and industrial laboratories throughout the world have led to the emergence of new generation olefin polymerization catalysts and polyolefin products. The purpose of this article is to highlight some of the major events that have occurred in the area of Ziegler- Natta catalysis and to illustrate the contributions of organometallic chemistry in the exciting story of the evolution of well-defined, 'single-site' metallocene catalysts. The developments in the mechanistic understanding of key steps of polymerization processes such as generation of active species, chain propagation and chain termination emerging from organometallic modeling studies are also highlighted. Also, the recent discovery of late transition metal olefin polymerization catalyst systems and its implications for further research in Ziegler- Natta catalysis is described.

Is learning basic care skills affected by parental participation in care? Part 1 (2001)

Parental participation in care is the accepted philosophy in British paediatric nursing. The consequences of that participation on the learning of basic skills by nurses in the clinical setting have not been investigated. This study explored the effects of parental participation in care on basic care skills using the experiences of eight nurses (four experienced nurses qualified more than five years and four nurses qualified less than one year) using Heideggarian hermeneutic phenomenology. Five themes were identified which reveal that the opportunities to learn and practise basic skills, although still important, are being limited by parental participation in care.
Microfluidic single-cell whole-transcriptome sequencing (2014)

Single-cell whole-transcriptome analysis is a powerful tool for quantifying gene expression heterogeneity in populations of cells. Many techniques have, thus, been recently developed to perform transcriptome sequencing (RNA-Seq) on individual cells. To probe subtle biological variation between samples with limiting amounts of RNA, more precise and sensitive methods are still required. We adapted a previously developed strategy for single-cell RNA-Seq that has shown promise for superior sensitivity and implemented the chemistry in a microfluidic platform for single-cell whole-transcriptome analysis. In this approach, single cells are captured and lysed in a microfluidic device, where mRNAs with poly(A) tails are reverse-transcribed into cDNA. Double-stranded cDNA is then collected and sequenced using a next generation sequencing platform. We prepared 94 libraries consisting of single mouse embryonic cells and technical replicates of extracted RNA and thoroughly characterized the performance of this technology. Microfluidic implementation increased mRNA detection sensitivity as well as improved measurement precision compared with tube-based protocols. With 0.2 M reads per cell, we were able to reconstruct a majority of the bulk transcriptome with 10 single cells. We also quantified variation between and within different types of mouse embryonic cells and found that enhanced measurement precision, detection sensitivity, and experimental throughput aided the distinction between biological variability and technical noise. With this work, we validated the advantages of an early approach to single-cell RNA-Seq and showed that the benefits of combining microfluidic technology with high-throughput sequencing will be valuable for large-scale efforts in single-cell transcriptome analysis.
