Ein α‐Methylanthrachinon aus Streptomyceten (1989)

An α‐Methylanthraquinone from Streptomycetes From cultures of several streptomycete strains producing isochromanquinone antibiotics ( 4 , 5 ), 3,8‐dihydroxy‐1‐methylanthraquinone‐2‐carboxylic acid ( 2b ), one of the rare naturally occurring α‐methylanthraquinones, was isolated. Native compounds of this group became known only as insect pigments (e.g. 1d ) and later on as constituents of a few plants. A common biosynthesis of benzoisochromanquinones and α‐methylanthraquinones is discussed.

Environmental and Genetic Risk Factors for Childhood Leukemia: Appraising the Evidence (2005)

Childhood leukemia is the most common cause of malignancy under the age of 15, representing an annual incidence rate of 43 cases per million in the United States. Confirmed clinical and epidemiologic associations explain less than 10% of disease incidence, leaving 90% of cases with an unclear etiology. To effectively study leukemia in children, one must recognize that this disease has a multifactorial causal mechanism and a heterogeneous biological composition. In addition, the timing of environmental exposures and genetic changes related to disease risk must be considered. This review of both environmental and genetic risk factors for childhood leukemia evaluates the current published literature and synthesizes the available knowledge. Furthermore, attention is directed to expected sources of new advances and the compelling current issues that need to be addressed before further progress can be made. We discuss parental occupational exposures, air pollution, other chemical exposures such as household solvents and pesticides, radiation, dietary factors, immunological factors, socioeconomic status, and genetic susceptibility. We hope to provide the reader with an understanding of the challenge and promise that characterizes the current and future directions in childhood leukemia research.
Alternatives to and Reduction of Animal Use in Biomedical Research, Education and Testing (1990)

Biomedical endeavours can be divided into three major categories: research, education, and testing. Within the context of each of these categories, activities involving whole animals have made major contributions and will continue to do so in the future. However, with technological developments in the areas of biotechnology and computers, new methods are already reducing the use of whole animals in certain areas. This article discusses the general issues of alternatives and then focuses on the development of new approaches to toxicity testing.
Predicting risk for medical malpractice claims using quality-of-care characteristics. (1992)

The current fault-based tort system assumes that claims made against physicians are inversely related to the quality of care they provide. In this study we identified physician characteristics associated with elements of medical care that make physicians vulnerable to malpractice claims. A sample of physicians (n = 248) thought to be at high or low risk for claims was surveyed on various personal and professional characteristics. Statistical analysis showed that 9 characteristics predicted risk group. High risk was associated with increased age, surgical specialty, emergency department coverage, increased days away from practice, and the feeling that the litigation climate was "unfair." Low risk was associated with scheduling enough time to talk with patients, answering patients' telephone calls directly, feeling "satisfied" with practice arrangements, and acknowledging greater emotional distress. Prediction was more accurate for physicians in practice 15 years or less. We conclude that a relationship exists between a history of malpractice claims and selected physician characteristics.
A new design for digital adaptive filters (1983)

Abstract The design and operation of a digital adaptive filter based on a modified Widrow-Hoff algorithm is described. It uses LSI components as main elements. This filter realization converges faster than other realizations reported hitherto because its weight vector is updated at every sampling instant.
Metalorganic Chemical Vapor Deposition of c-Axis Oriented PZT Thin Films (1990)

Ferroelectric PZT thin films were prepared by the simultaneous deposition of PbO, ZrO 2 and TiO 2 on heated substrates under a reduced pressure of 6 Torr. Both tetraethyl lead-zirconium tetraisopropoxide and tetradipivaloylmethane-titanium tetraisopropoxide systems were examined as source materials. The films obtained at 500° to 650°C with those systems were constituted of PZT of the single perovskite phase, and highly c -axis-oriented films were grown on MgO(100) with the latter system. The c -axis orientation suggests an epitaxial growth of PZT on the substrates. With increasing molar fraction of ZrO 2 in the PZT, the crystals were transformed from a tetragonal to rhom-bohedral structure. The film deposition rates were 100 to 1000 Å/min, i.e., more than ten times those obtained by the conventional sputtering method.
Complications, Re-Intervention Rates, and Natural History of Residual Stone Fragments After Percutaneous Nephrolithotomy (2017)

The true stone-free rate was 55% after PCNL. However, 82.5% were stone free or had RFs 4 mm or less, which correlates with previous studies. Larger RFs had higher rates of stone-related events and shorter time to occurrence of stone-related events. The growth and spontaneous passage of RFs was independent of RF size, emphasizing the importance of obtaining a stone-free status after PCNL.

Evolving Concepts of Asthma (2015)

Our understanding of asthma has evolved over time from a singular disease to a complex of various phenotypes, with varied natural histories, physiologies, and responses to treatment. Early therapies treated most patients with asthma similarly, with bronchodilators and corticosteroids, but these therapies had varying degrees of success. Similarly, despite initial studies that identified an underlying type 2 inflammation in the airways of patients with asthma, biologic therapies targeted toward these type 2 pathways were unsuccessful in all patients. These observations led to increased interest in phenotyping asthma. Clinical approaches, both biased and later unbiased/statistical approaches to large asthma patient cohorts, identified a variety of patient characteristics, but they also consistently identified the importance of age of onset of disease and the presence of eosinophils in determining clinically relevant phenotypes. These paralleled molecular approaches to phenotyping that developed an understanding that not all patients share a type 2 inflammatory pattern. Using biomarkers to select patients with type 2 inflammation, repeated trials of biologics directed toward type 2 cytokine pathways saw newfound success, confirming the importance of phenotyping in asthma. Further research is needed to clarify additional clinical and molecular phenotypes, validate predictive biomarkers, and identify new areas for possible interventions.
Automated Verification Methodology of Security Events Based on Heuristic Analysis (2015)

We present an automated verification methodology of the security events, that is, IDS alerts, based on heuristic analysis. The proposed verification methodology aims to automatically identify real cyberattacks from the security events and filter out false positive, so that the security analyst is able to conduct security monitoring and response more effectively. For the proposed verification methodology, we used the 1,528,730,667 security events that were obtained from Science and Technology Security Center (S&T-SEC). We then extracted the core security events that were caused by the real cyberattacks. Among the core security events, we selected the top 20 types of the security events in the number of the real attacks that they raised. By analyzing the top 20 types of the security events, we discovered essential elements and optional elements for using in the automated verification of the security events. The evaluation results showed that the proposed verification methodology could contribute to the reduction (about 67%) of the meaningless security events. Furthermore, we demonstrated that the proposed verification methodology contributed to the detection of 140 true negatives that were not identified by the security analyst and the total accuracy of the proposed verification methodology was 96.1%.

Green synthesis and characterization of flower-like PbS and metal-doped nanostructures via hydrothermal method (2017)

Abstract In this work, flower-like nanoparticles of lead sulfide (PbS) and metal-doped PbS nanostructures were synthesized via a simple hydrothermal method in water as a green solvent. The effect of temperature, precipitating agent and capping agent on the morphology and particle size of the products was investigated. Sugars were used as green, safe, cost-effective, and bio-compatible capping agents. The prepared products were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and ultra violet-visible spectroscopy. The effect of PbS as a photocatalyst on the degradation of three different azo dyes was investigated. Acid brown, acid violet, and acid blue were totally degraded at 60 min under ultra-violet irradiation.
A two-dimensional finite-element analysis of reverberation chambers (1999)

A two-dimensional (2-D) analysis of reverberation chambers is performed at cutoff. The structure considered is lossless and corresponds to an infinite quality factor (Q) chamber. The concept of frequency stirring is used to generate field data for a discrete set of modes and the resulting statistics are analyzed. The field statistics are examined for TE and TM modes. This analysis yields statistics similar to the expected reverberation chamber statistics for the fields. Mechanical stirring is also examined and a connection to the peak-frequency deviation is presented.
Dose-Dependent Protection against or Exacerbation of Disease by a Polylactide Glycolide Microparticle-Adsorbed, Alphavirus-Based Measles Virus DNA Vaccine in Rhesus Macaques (2008)

Measles remains an important cause of vaccine-preventable child mortality. Development of a low-cost, heat-stable vaccine for infants under the age of 6 months could improve measles control by facilitating delivery at the time of other vaccines and by closing a window of susceptibility prior to immunization at 9 months of age. DNA vaccines hold promise for development, but achieving protective levels of antibody has been difficult and there is an incomplete understanding of protective immunity. In the current study, we evaluated the use of a layered alphavirus DNA/RNA vector encoding measles virus H (SINCP-H) adsorbed onto polylactide glycolide (PLG) microparticles. In mice, antibody and T-cell responses to PLG-formulated DNA were substantially improved compared to those to naked DNA. Rhesus macaques received two doses of PLG/SINCP-H delivered either intramuscularly (0.5 mg) or intradermally (0.5 or 0.1 mg). Antibody and T-cell responses were induced but not sustained. On challenge, the intramuscularly vaccinated monkeys did not develop rashes and had lower viremias than vector-treated control monkeys. Monkeys vaccinated with the same dose intradermally developed rashes and viremia. Monkeys vaccinated intradermally with the low dose developed more severe rashes, with histopathologic evidence of syncytia and intense dermal and epidermal inflammation, eosinophilia, and higher viremia compared to vector-treated control monkeys. Protection after challenge correlated with gamma interferon-producing T cells and with early production of high-avidity antibody that bound wild-type H protein. We conclude that PLG/SINCP-H is most efficacious when delivered intramuscularly but does not provide an advantage over standard DNA vaccines for protection against measles.

Efficient and scalable cache coherence schemes for shared memory hypercube multiprocessors (2002)

Large scale shared memory multiprocessors use a directory based cache coherence scheme. The basic directory scheme, called full-map, is efficient but has a large memory overhead. Therefore, limited directory schemes have been proposed which limit the number of pointers in the directories. These schemes tradeoff smaller memory overhead for larger memory access latencies. We propose a new limited directory scheme, which achieves lower memory overhead as well as smaller memory access latencies. The scheme uses ring embedding in a hypercube in conjunction with wormhole routing to reduce the invalidation delays. The proposed scheme performs as good as full-map for smaller degree of sharing and performs better than full-map for larger degree of sharing.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The Benefits and Costs of Serious Running (2001)

Abstract The primary purpose of this investigation was to determine the benefits and costs of serious running. Twenty-four runners, 12 females and 12 males with a wide range of demographic characteristics who entered and completed at least three 5K road races were selected for in-depth interviews. The results indicated that although people run for a variety of reasons, a sense of accomplishment appeared as the number one theme in this research. The runners in this study viewed a sense of accomplishment as a substantial benefit, as well as being a source of extended meaning. Health and fitness, as well as social affiliation, were also important for both initial participation and ongoing continuation and for the meaning that running held in their lives. Costs included injuries, letting oneself down, and concern for one's safety was salient for all female runners. The issue of fear was a theme that arose for female runners. Female runners considered the fear of being attacked a cost that influenced when, how, and with whom they ran. Female runners' running careers were negatively affected as a result of being concerned for their safety. It did not emerge nor was it discussed with male runners. Further research is needed to provide a more comprehensive understanding of the notion of power and control for females generally and more specifically for females in the exercise domain. Whether this sense of “empowerment” is present for females in other serious leisure or sport activities remains to be determined.
Autofluorescence excitation-emission matrices for diagnosis of colonic cancer (2005)

Leukotrienes in health and disease (1987)

The leukotrienes (LTs) are 5-lipoxygenase metabolites of arachidonic acid. The synthesis and release of LTs have been demonstrated in many cells and organs, and LTs are considered to be normal products of continuous metabolism of arachidonic acid. However, although evidence in favor of a critical role for LTs in regulation of physiological functions is still scarce, a growing body of evidence suggests a role for LTs in mediation of several pathophysiological processes such as generalized or local immune reactions, inflammation, asthma, shock, and trauma. LTs have been shown to have potent actions on many essential organs and systems, including the cardiovascular system (heart, blood vessels, microcirculation), the pulmonary system (lung, airways), the central nervous system (neural, glial, and vascular elements), the gastrointestinal tract, and the immune system. In these organs the effects of LTs are mediated by specific LT receptors. Identification of LTs and characterization of their regional and systemic pathological effects, together with characterization of their receptors and elucidation of their structure-activity relationships, are fundamental to developing LT antagonists or synthesis inhibitors that might prevent or reverse LT-dependent reactions. Preliminary reports have already shown that such pharmacological agents ameliorate some aspects of disease processes in experimental animals as well as in humans. In this brief review we intend to highlight the evidence that implicates LTs in normal physiological functions as well as in disease processes.
Characteristics of two cell lines (TE-1 and TE-2) derived from human squamous cell carcinoma of the esophagus. (1979)

Two epithelial cell lines (TE-1 and TE-2) have been established from a well or poorly differentiated human squamous cell carcinoma of the esophagus. TE-1 has been subcultured 120 times during 2 years and 10 months, and TE-2, 50 times for almost 2 years. Cultured cells grew as isolated and piled-up colonies of epithelial cells. The average doubling time of the TE-1 cell line was 60 hr and that of TE-2, 72 hr. Distinctive marker chromosomes and a male karyotype were present in TE-1, but no marker chromosomes were seen in TE-2. Scanning electron microscopic examinations of both TE-1 and TE-2 confirmed the presence of desmosomes and interdigitated microvilli. Transmission electron micrographs of TE-1 showed the presence of abundant cell organelles, and a few organelles were found in the scanty cytoplasm of TE-2. There was a marked difference in the cell organelles between TE-1 and TE-2. Heterotransplantation of the cultured TE-1 and TE-2 cells produced tumors, the histological appearance of which was similar to that of the original ones. The carcinoembryonic antigen level of the medium in the confluent culture of TE-2 was 270 ng/10(6) cells. In the cytoplasm of TE-1 cells the number of paracrystals, which were produced by treatment with vinblastine sulfate, increased by the addition of cholera toxin to the medium.
