Serial plasma carcinoembryonic antigen measurements during treatment of metastatic breast cancer. (1983)

Serial plasma carcinoembryonic antigen (CEA) levels were measured in 167 patients with metastatic breast cancer treated with fluorouracil, doxorubicin hydrochloride, and cyclophosphamide (FAC). In 84 patients, the pretreatment CEA value was abnormal. Response rates and remission duration were similar in patients with normal and abnormal pretreatment levels. Carcinoembryonic antigen concentrations decreased in 94% of patients who responded to FAC therapy. The duration of response was 22 months for patients in whom the CEA levels normalized v nine months in those in whom it decreased but never returned to normal. Increasing CEA levels correlated with progressive disease in 87% of patients and preceded clinical evidence of progression in 77%. Serial CEA measurements can monitor response to chemotherapy, provide useful prognostic information of response duration, and detect progressive disease early.
Faecal microbiota transplantation and bacteriotherapy for recurrent Clostridium difficile infection: A retrospective evaluation of 31 patients (2013)

Increasing resistance on the part of anaerobes to several antimicrobial agents has been a problem in recent years. Mechanisms of resistance include production of inactivating enzymes such as beta-lactamases, plasmid-mediated transferable resistance and failure of the drug to penetrate the bacterial cell. Fortunately, availability of several new agents permits us to treat anaerobic infections effectively. However, it is now desirable to do routine in vitro susceptibility testing of anaerobes, especially in seriously ill patients. Newly introduced drugs and others still undergoing study are compared with the standard agents.
Musical Onset Detection Based on Adaptive Linear Prediction (2006)

A new musical onset detection technique based on adaptive linear prediction theory is proposed in this work. We decompose a music signal into multiple sub-bands, and then apply a forward linear prediction error filter (LPEF) to model the narrow-band signal in each band, respectively. To enhance the modeling performance, the coefficients of the LPEF are updated with the least-mean-squares (LMS) algorithm. Under this framework, the onset detection problem can be formulated as the peak-error location problem. Peak selection algorithms are applied to prediction errors to locate the onset time. It is shown by experimental results that the proposed algorithm outperforms several well known existing methods for onset detection
The Chemistry of Silica: Solubility, Polymerization, Colloid and Surface Properties and Biochemistry of Silica (1979)

Surfactants and Interfacial Phenomena Milton J. Rosen Bridging the gap between purely theoretical aspects of surface chemistry and the purely empirical experience of the industrial technologist, this book applies theoretical surface chemistry to understanding the action of surfactants in modifying interfacial phenomena. It surveys the structural types of commercially available surfactants and discusses interfacial phenomena, the physicochemical principles underlying the action of surfactants in each phenomenon, and the effect of structural changes in the surfactants and environmental changes on their action. Tables of data on various interfacial properties of surfactants, compiled and calculated from the latest scientific literature, are included. 1978 304 pp. An Introduction to Clay Colloid Chemistry, 2nd Ed. H. van Olphen This book provides valuable guidance in research and design efforts by giving a clear understanding of principles and concepts of colloid chemistry as applied to clay systems. Updated and enlarged, this edition includes new information on surface characterization and adsorption mechanisms; recent results in the area of clay-organic interaction-the intercalation and intersalation of kaolinite minerals; and increased attention to the possible role of clays in biological evolution. 1977 318 pp. Physicochemical Processes for Water Quality Control Walter J. Weber, Jr. Focusing on physicochemical rather than biological processes, this book presents a comprehensive treatise on the treatment of municipal and industrial water and wastewater. All of the physicochemical processes important to municipal and industrial water and wastewater treatment-coagulation, filtration, membrane processes, chemical oxidation, and others-are included and each is covered thoroughly from principle through application. To maintain a high level of expertise, contributions have been incorporated from specialists actively involved in research or engineering applications in ea

Inhibition of Schwann cell myelination in vitro by antibody to the L1 adhesion molecule (1990)

The specific axonal and Schwann cell surface molecules that mediate the initiation of myelination have not been identified. We have used cocultures of purified rat dorsal root ganglion neurons and Schwann cells and purified polyclonal antibodies to the L1 adhesion molecule to study the role of L1 in myelin formation. Schwann cells were first arrested in a basal-lamina-free premyelination stage (by serum/ascorbate deprivation), then manipulated to allow basal lamina deposition and myelination (by serum/ascorbate addition) in the absence or presence of anti-L1. Using electron microscopy, immunocytochemistry, and myelin sheath quantitation after Sudan-black staining, we determined the effect of anti-L1 on (1) basal lamina formation, (2) the segregation by Schwann cells of axons into a 1:1 relationship, (3) galactocerebroside (Gal-C) expression, (4) laminin deposition, and (5) myelin formation. Anti-L1 strongly blocked myelin formation, Gal-C expression, and axon segregation but did not block basal lamina formation. In controls, elongated Schwann cell processes completely covered the axons and exhibited uniform surface staining for laminin; in anti-L1-treated cultures, shortened Schwann cells, intensely stained for laminin, were observed in clusters separated by unstained lengths of axons. When 50 micrograms/ml exogenous purified laminin was added to the medium, Schwann cell length and laminin staining were similar in control and treated cultures. However, the inhibition of myelination of anti-L1 was not altered by the addition of laminin. Myelination was also inhibited with antigen-binding fragments (Fab) of polyclonal anti-L1, but an antibody to liver membranes did not block myelination. These results indicate that L1 is involved in the linear extension of Schwann cell processes along axons, the engulfment of axons, and the induction of myelin-specific components within the Schwann cell. We conclude that anti-L1 prevents myelination by blocking these events rather than by blocking basal lamina deposition.
Hyposecretion of adrenal androgens and the relation of serum adrenal steroids, serotonin and insulin-like growth factor-1 to clinical features in women with fibromyalgia (1999)

Neuroendocrine deficiencies have been implicated in fibromyalgia (FM). In the present study, adrenal androgen metabolites and their relationship with health status in FM were investigated. For comparison, serum levels of other implicated neuroendocrine mediators were correlated with health status. Fifty-seven consecutive women with FM completed the Fibromyalgia Impact Questionnaire (FIQ). Fasting blood samples were taken for measurement of dehydroepiandrosterone sulphate (DHEAS), free testosterone (T), cortisol, serotonin and insulin-like growth factor-1. Normal value for DHEAS and T were obtained from 114 controls. DHEAS levels were decreased significantly in pre- and postmenopausal patients (P<0.0001 and P<0.0005, respectively). T levels were decreased significantly in premenopausal and insignificantly in postmenopausal patients (P<0.0001 and P=0.06, respectively). The following correlations between neurohormonal levels and FIQ scores were found: DHEAS (after adjustment for age) vs. pain (P<0.001) and T (after adjustment for age) versus physical functioning (P=0.002). None of the other neurohormonal levels correlated significantly with any of the FIQ scores. IGF-1 levels were lower in the obese patients as compared to those who were non-obese (P=0.03). The BMI correlated positively with pain (P<0. 001) and inversely with DHEAS levels (P=0.006). After further adjustment for BMI, the correlation between age adjusted DHEAS and pain was no longer significant. Hyposecretion of adrenal androgens was documented in FM. This was more pronounced in obese patients. Low serum androgen levels correlated with poor health status in FM. Longitudinal studies are needed to elucidate whether these are cause and/or effect relationships.
Effectiveness of Bed Bug Monitors for Detecting and Trapping Bed Bugs in Apartments (2011)

Bed bugs, Cimex lectularius L., are now considered a serious urban pest in the United States. Because they are small and difficult to find, there has been strong interest in developing and using monitoring tools to detect bed bugs and evaluate the results of bed bug control efforts. Several bed bug monitoring devices were developed recently, but their effectiveness is unknown. We comparatively evaluated three active monitors that contain attractants: CDC3000, NightWatch, and a home-made dry ice trap. The Climbup Insect Interceptor, a passive monitor (without attractants), was used for estimating the bed bug numbers before and after placing active monitors. The results of the Interceptors also were compared with the results of the active monitors. In occupied apartments, the relative effectiveness of the active monitors was: dry ice trap > CDC3000 > NightWatch. In lightly infested apartments, the Interceptor (operated for 7 d) trapped similar number of bed bugs as the dry ice trap (operated for 1 d) and trapped more bed bugs than CDC3000 and NightWatch (operated for 1 d). The Interceptor was also more effective than visual inspections in detecting the presence of small numbers of bed bugs. CDC3000 and the dry ice trap operated for 1 d were equally as effective as the visual inspections for detecting very low level of infestations, whereas 1-d deployment of NightWatch detected significantly lower number of infestations compared with visual inspections. NightWatch was designed to be able to operate for several consecutive nights. When operated for four nights, NightWatch trapped similar number of bed bugs as the Interceptors operated for 10 d after deployment of NightWatch. We conclude these monitors are effective tools in detecting early bed bug infestations and evaluating the results of bed bug control programs.
Molecular Beam Epitaxy of SrTiO3 Films on Si(100)-2×1 with SrO Buffer Layer (1998)

Molecular beam epitaxy of SrTiO 3 thin films on a Si(100)-2×1 surface has been studied using reflection high-energy electron diffraction (RHEED), an atomic force microscope (AFM) and X-ray diffraction (XRD) as a function of the thickness of the SrO buffer layer and growth temperature. Epitaxial SrTiO 3 films do not grow directly on Si(100). Therefore, a SrO buffer layer was applied to grow SrTiO 3 on Si(100). It was found that the SrO layer with a thickness of 100 Å grown at 300 – 400°C in oxygen atmosphere of 5 ×10 -8 Torr was sufficient to grow epitaxial SrTiO 3 on Si(100). Then SrTiO 3 thin films with a thickness of 2000 Å were grown on the SrO(100Å)/Si surface at 400 – 700°C using codeposition of strontium and titanium in oxygen atmosphere of 8×10 -8 Torr. At 500°C, the best-quality SrTiO 3 (100) film grew parallel to Si(100), and numerous rectangular platelike crystals were observed on the surface in the AFM image. The crystallinity of the STO films was improved with increasing thickness of the SrO layer. The epitaxial relation between SrTiO 3 and SrO/Si(100)-2×1 is also discussed using the RHEED patterns which show streaks and spots.
Experimental Evidence for Soliton Explosions (2002)

We show, experimentally and numerically, that Ti:sapphire mode-locked lasers can operate in a regime in which they intermittently produce exploding solitons. This happens when the laser operates near a critical point. Explosions happen spontaneously, but external perturbations can trigger them. In stable operation, all explosions have similar features, but are not identical. The characteristics of the explosions depend on the intracavity dispersion.
Plitidepsin has potent preclinical efficacy against SARS-CoV-2 by targeting the host protein eEF1A (2021)

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral proteins interact with the eukaryotic translation machinery, and inhibitors of translation have potent antiviral effects. We found that the drug plitidepsin (aplidin), which has limited clinical approval, possesses antiviral activity (90% inhibitory concentration = 0.88 nM) that is more potent than remdesivir against SARS-CoV-2 in vitro by a factor of 27.5, with limited toxicity in cell culture. Through the use of a drug-resistant mutant, we show that the antiviral activity of plitidepsin against SARS-CoV-2 is mediated through inhibition of the known target eEF1A (eukaryotic translation elongation factor 1A). We demonstrate the in vivo efficacy of plitidepsin treatment in two mouse models of SARS-CoV-2 infection with a reduction of viral replication in the lungs by two orders of magnitude using prophylactic treatment. Our results indicate that plitidepsin is a promising therapeutic candidate for COVID-19.
Additional aids to the remineralisation of tooth structure (2005)

When tryptophyl side chains are hidden within relatively inflexible domains of globular proteins, the lifetime of the phosphorescence from these residues provides a measure of the local conformational flexibility. The phosphorescence decay from the tryptophan buried at the base of the nucleotide-binding domain in liver alcohol dehydrogenase (alcohol:NAD+ oxidoreductase, EC 1.1.1.1) was monitored between 1 and 40 degrees C to determine the energetics associated with the rate of local unfolding. The slow rate at which this process takes place is found to result from a high entropic barrier rather than from the disruption of strong intramolecular interactions. This observation along with the response of the system to solvent perturbations points to the significance of solvent-protein interactions in determining conformational flexibility.
Long noncoding RNA-mediated intrachromosomal interactions promote imprinting at the Kcnq1 locus (2014)

Kcnq1ot1 is a long noncoding ribonucleic acid (RNA; lncRNA) that participates in the regulation of genes within the Kcnq1 imprinting domain. Using a novel RNA-guided chromatin conformation capture method, we demonstrate that the 5' region of Kcnq1ot1 RNA orchestrates a long-range intrachromosomal loop between KvDMR1 and the Kcnq1 promoter that is required for maintenance of imprinting. PRC2 (polycomb repressive complex 2), which participates in the allelic repression of Kcnq1, is also recruited by Kcnq1ot1 RNA via EZH2. Targeted suppression of Kcnq1ot1 lncRNA prevents the creation of this long-range intrachromosomal loop and causes loss of Kcnq1 imprinting. These observations delineate a novel mechanism by which an lncRNA directly builds an intrachromosomal interaction complex to establish allele-specific transcriptional gene silencing over a large chromosomal domain.
In Vitro and In Vivo Biology of Recombinant Adenovirus Vectors with E1, E1/E2A, or E1/E4 Deleted (1998)

Isogenic, E3-deleted adenovirus vectors defective in E1, E1 and E2A, or E1 and E4 were generated in complementation cell lines expressing E1, E1 and E2A, or E1 and E4 and characterized in vitro and in vivo. In the absence of complementation, deletion of both E1 and E2A completely abolished expression of early and late viral genes, while deletion of E1 and E4 impaired expression of viral genes, although at a lower level than the E1/E2A deletion. The in vivo persistence of these three types of vectors was monitored in selected strains of mice with viral genomes devoid of transgenes to exclude any interference by immunogenic transgene-encoded products. Our studies showed no significant differences among the vectors in the short-term maintenance and long-term (4-month) persistence of viral DNA in liver and lung cells of immunocompetent and immunodeficient mice. Furthermore, all vectors induced similar antibody responses and comparable levels of adenovirus-specific cytotoxic T lymphocytes. These results suggest that in the absence of transgenes, the progressive deletion of the adenovirus genome does not extend the in vivo persistence of the transduced cells and does not reduce the antivirus immune response. In addition, our data confirm that, in the absence of transgene expression, mouse cellular immunity to viral antigens plays a minor role in the progressive elimination of the virus genome.
Modeling Intestinal Absorption and Other Nutrition-Related Processes Using PSPICE and STELLA (1990)

In summary, SPICE models are constructed by translating a highly organized biological system into a network diagram by using a disciplined, systematic method for converting flows through barriers and chemical reactions into branches in a network connecting the compartments in the tissue according to the identity of the flowing entities. The first step in building a simulation model is essentially the same as the first step in learning about the method. Simple mechanisms are mastered first; and then as proficiency and understanding of the system grow, these can be connected and elaborated to produce simulations more closely approximating the real complexity of the living system. Other methods exist that may be easier to deal with initially, but often they cannot be utilized as generally as SPICE owing to their inherent limitations. One program available on Apple machines that has a high degree of user friendliness is STELLA. We will make some brief comparisons here, since STELLA is often an easier way to get started in simulation and often perfectly adequate for smaller problems.

Curve-to-curve associations in spline-based inbetweening and sweeping (1989)

We are concerned in this paper with associations between spline curves that will hold at all inbetween positions when the control points of these curves are used as key points for animation or sweeping. It is established that any association between two spline curves that can be expressed as the equality of two linear mappings will hold throughout an inbetweening process provided the inbetweening trajectories are coordinated splines that uniquely interpolate the control-point key positions. Multiple associations are possible, so long as the basic requirements of linearity and coordination are observed.
A comprehensive study of genic variation in natural populations of Drosophila melanogaster. IV. Mitochondrial DNA variation and the role of history vs. selection in the genetic structure of geographic populations. (1991)

Preliminary studies with restriction fragment length polymorphisms of mitochondrial DNA (mtDNA) in natural populations of Drosophila melanogaster revealed considerable variation in terms of nucleotide sequence and overall size. In this report we present data from more isofemale lines and more restriction enzymes, and explore the utility of the data in inferring a colonization history of this species. Size variation in the noncoding A + T-rich region is particularly plentiful, with size variants occurring in all restriction site haplotypes in all populations. We report here classes of small-scale mobility polymorphisms (apparent range of 20 bp) in specific restriction fragments in the coding region. The variation in one such fragment appears to be generated even more rapidly than in the noncoding region. On the basis of the distribution of restriction site haplotypes, the species range can be divided into three major regions along longitudinal lines: Euro-African populations are the most diverse and are taken to be oldest; Far East populations have a complex distribution of haplotypes; Western Hemisphere populations are the least diverse and are interpreted to be the youngest. The history inferred from mtDNA alone is remarkably similar to one based on several nuclear markers. The mtDNA haplotype distribution is also very different from that of allozymes in these same populations. We interpret this as further evidence that natural selection is still the most parsimonious explanation for the parallel latitudinal allozyme clines in this species.
