Wetting and strength in the tin–silver–titanium/sapphire system (2004)

The wetting of tin-silver-based alloys on Al 2 O 3 has been studied using the sessile-drop configuration. Small additions of Ti decrease the contact angle of Sn-3 wt.% Ag alloys on alumina from 150° to 25°. However, a wide variability in contact angles and spreading rates is observed. The variability is related to the kinetics of Ti dissolution in the alloy and the formation of triple-line ridges. Enhanced spreading is not accompanied by the formation of a continuous reaction layer at the metal/ceramic interface. Furthermore, no reaction product could be detected after tests performed at temperatures below 800 °C. The average mechanical strength of metal-ceramic bonds fabricated under parallel conditions ranged between 40-110 MPa. In all cases, fracture of the joints occurred at the metal-ceramic interface. The formation of a discontinuous reaction product decreases the strength of the bonds fabricated at higher temperatures.
Achieving a clinically relevant composite outcome of an HbA1c of <7% without weight gain or hypoglycaemia in type 2 diabetes: a meta‐analysis of the liraglutide clinical trial programme (2011)

As assessed by the composite outcome of HbA1c <7%, no hypoglycaemia and no weight gain, liraglutide was clearly superior to the other commonly used therapies. However, the long-term clinical impact of this observation remains to be shown.
Effects of histamine and the histamine antagonists mepyramine and cimetidine on human coronary arteries in vitro (1983)

The effects of histamine have been studied on human isolated coronary artery preparations taken from hearts ranging in age from 9 to 73 years. Histamine in large concentrations (100 microM) contracted arteries which were without tone or spontaneous activity and sometimes induced rhythmic contractile activity. If spontaneous rhythmic activity was present it was enhanced by histamine. The contractile effects of histamine were inhibited by mepyramine but not by cimetidine. Arteries which were contracted by depolarization responded with relaxation to histamine concentrations lower than those required to evoke a contraction; arteries from younger hearts were more sensitive than those from older hearts. Mepyramine potentiated the maximal relaxant effect of histamine in arteries from hearts of all ages but cimetidine had very little effect. In the presence of mepyramine, cimetidine antagonized the relaxant effect of histamine, shifting the concentration-effect curve to the right. It is concluded that human coronary arteries contain both H1- and H2-type receptors, the H1-receptors mediating contraction. The relaxant effects of histamine can only be inhibited by a combination of both H1- and H2-receptor antagonists.
Revising FUNSD dataset for key-value detection in document images (2020)

FUNSD is one of the limited publicly available datasets for information extraction from document im-ages. The information in the FUNSD dataset is defined by text areas of four categories ("key", "value", "header", "other", and "background") and connectivity between areas as key-value relations. In-specting FUNSD, we found several inconsistency in labeling, which impeded its applicability to thekey-value extraction problem. In this report, we described some labeling issues in FUNSD and therevision we made to the dataset. We also reported our implementation of for key-value detection onFUNSD using a UNet model as baseline results and an improved UNet model with Channel-InvariantDeformable Convolution.
Anti‐interleukin‐33 inhibits cigarette smoke‐induced lung inflammation in mice (2012)

The mechanism by which cigarette smoke (CS) causes chronic obstructive pulmonary disease (COPD) is poorly understood. Interleukin-33 (IL-33) is a pleiotropic cytokine predominantly expressed in lung tissue and can elicit airway inflammation in naive mice. We tested the hypothesis that IL-33 is induced by CS and contributes to CS-mediated airway inflammation in a mouse model of CS-induced COPD. Groups of mice were exposed to CS three times per day for 4 consecutive days. The expression levels of IL-33 and ST2 were markedly enhanced in the lung tissue of mice inhaling CS. Exposure to CS also induced neutrophil and macrophage infiltration and expression of inflammatory cytokines (IL-1β, tumour necrosis factor-α, IL-17), chemokines (monocyte chemoattractant protein-1) and mucin 5, subtypes A and C in the airways. More importantly, all of these CS-induced pathogenic changes were significantly inhibited by treatment with neutralizing anti-IL-33 antibody delivered intranasally. Hence, our results suggest that IL-33 plays a critical role in CS-mediated airway inflammation and may be a therapeutic target in CS-related diseases, including COPD.
Abstract A100: STAT3 as a novel cancer prevention target in colorectal cancer stem cells (2010)

Abstract Constitutive activation of signal transducers and activators of transcription 3 (STAT3) signaling is frequently detected in human cancer including colon cancer, and has emerged as an attractive molecular target for cancer prevention. Recent experimental evidence suggests that the existence of a small population of tumorigenic stem/progenitor cells may be responsible for tumor initiation, chemotherapy and radiation resistance, invasion, recurrence, and metastasis. An increasing body of evidence suggests that the cancer stem cell concept is also relevant to colorectal cancer. To date, however, whether STAT3 is activated in colon cancer stem cells or cancer-initiating cells and what the role of STAT3 signaling may play in these cancer stem cells is still unknown. If STAT3 is activated in colorectal cancer stem cells, inhibiting STAT3 may offer a promising opportunity to target colorectal cancer stem cells and prevent the recurrence of cancer. We utilized the colon cancer stem cells, which are characterized by an aldehyde dehydrogenase (ALDH)-positive (ALDH+) and CD133-positive (CD133+) subpopulation. We demonstrated that ALDH+/CD133+ cells have capacity than ALDH-/CD133- cells to form more tumorspheres and to exhibit more potent tumor-initiating ability in mice. We then examined the STAT3 activation in these colon cancer cells. Interestingly, we observed that the ALDH+/CD133+ subpopulation of colon cancer cells expressed higher levels of phosphorylated STAT3, an active form of STAT3, compared to the ALDH-/CD133- subpopulation and un-separated colon cancer cells, suggesting that STAT3 is activated in colon cancer stem cells. We demonstrated that dietary agent, curcumin and a new curcumin analog, GO-Y030 can inhibit STAT3 phosphorylation, cell viability, and induced apoptosis in colon cancer stem cells. The inhibition of STAT3 was confirmed using a novel STAT3-selecitve curcumin analog, FLLL32, STAT3 ShRNA, as well as STAT3 inhibitors, LLL12 and Stattic. All these STAT3 inhibitors, inhibited STAT3 phosphorylation, cell viability, and tumorsphere growth in colon cancer stem cells. Furthermore, both GO-Y030 and LLL12 inhibited tumor growth of colon cancer stem cells in NOD/SCID mouse model in vivo. In Summary, this is the first report to demonstrate that persistent STAT3 phosphorylation is expressed in colon cancer stem cells. Our study is also the first attempt to target STAT3 in colon cancer stem cells and we demonstrated for the first time that colon cancer stem cells are indeed sensitive to the inhibition by small molecular STAT3 inhibitors, FLLL32, LLL12, Stattic, STAT3 shRNA, and curcumin analog, GO-Y030. Our results suggest that STAT3 is a novel prevention target in colon cancer stem cells and inhibition of activated STAT3 in cancer stem cells may offer an effective preventive approach for colorectal carcinoma.

Effects of PSK on T and dendritic cells differentiation in gastric or colorectal cancer patients. (2005)

In the cancer-bearing state, the Th1/Th2 and DC/1/DC2 balance becomes Th2- and DC2-dominant. PSK therapy results in a shift of the Th1/Th2 and DC1/DC2 balance towards Th1 and DC1 dominance. We plan to examine whether combining dendritic cells (DC) vaccination therapy with oral PSK enhances the induction of T cell and DC differentiation in cancer patients.
210-OR: Long-Acting GIPR Agonism Enhances Body Weight Regulation of Multiple Weight-Reducing Agents in Diet-Induced Obese Mice (2023)

The development of multi-agonists targeting the glucose-dependent insulinotropic polypeptide receptor (GIPR) has resulted in significant clinical improvements in body weight management, however the contribution of GIPR agonism to this effect is incompletely understood. Using a diet induced obese (DIO) mouse model, GIPR agonism (LAGIPRA) alone has demonstrated little to no efficacy in weight management, whereas the addition of LAGIPRA to long acting GLP-1R agonism decreased food intake and increased energy expenditure resulting in greater weight loss compared with GLP-1R agonism alone suggesting a synergistic benefit. To determine whether GIPR agonism would provide similar synergistic improvements in energy metabolism with additional pharmacologic drivers of weight loss, we treated DIO mice with various weight reducing agents plus and minus LAGIPRA in metabolic chambers. Interestingly, addition of LAGIPRA enhanced weight loss, fat mass reduction, energy expenditure, and lipid oxidation whether combined with T3, FGF21, or long-acting glucagon (IUB288); consistent with earlier experiments, it had little effect on its own. Assessment of adipose tissue engagement in these and subsequent studies suggest GIPR agonism in this tissue may enhance lipolysis, potentially enabling greater energy expenditure via release of stored lipids. These findings suggest a unique role for GIPR agonism to regulate energy expenditure when combined with molecules that reduce body weight generating a greater negative caloric balance and enhancing body weight reduction.

Near-Field Scanning Microwave Microscopy in the Single Photon Regime (2019)

The microwave properties of nano-scale structures are important in a wide variety of applications in quantum technology. Here we describe a low-power cryogenic near-field scanning microwave microscope (NSMM) which maintains nano-scale dielectric contrast down to the single microwave photon regime, up to $10^{9}$ times lower power than in typical NSMMs. We discuss the remaining challenges towards developing nano-scale NSMM for quantum coherent interaction with two-level systems as an enabling tool for the development of quantum technologies in the microwave regime.

Effects of Potassium Loading over Iron–Silica Interaction, Phase Evolution and Catalytic Behavior of Precipitated Iron-Based Catalysts for Fischer-Tropsch Synthesis (2022)

Potassium (K) promoter and its loading contents were shown to have remarkable effects on the Fe–O–Si interaction of precipitated Fe/Cu/K/SiO2 catalysts for low-temperature Fischer-Tropsch synthesis (FTS). With the increase in K content from 2.3% (100 g Fe based) up to 7% in the calcined precursors, Fe–O–Si interaction was weakened, as reflected by ATR/FTIR, H2-TPR and XPS investigations. XRD results confirmed that the diffraction peak intensity from (510) facet of χ-Fe5C2 phase strengthened with increasing K loading, which indicates the crystallite size of χ-Fe5C2 increased with the increase in K contents either during the syngas reduction/carburization procedure or after FTS reaction. H2-TPH results indicated that more reactive surface carbon (alpha-carbon) was obtained over the higher K samples pre-carburized by syngas. Raman spectra illustrated that a greater proportion of graphitic carbon was accumulated over the surface of spent samples with higher K loading. At the same time, ATR-FTIR, XRD and Mössbauer spectra (MES) characterization results showed that a relatively higher level of bulk phase Fayalite (Fe2SiO4) species was observed discernibly in the lowest K loading sample (2.3 K%) in this work. The catalytic evaluation results showed that the CO conversion, CO2 selectivity and O/P (C2–C4) ratio increased progressively with the increasing K loading, whereas a monotonic decline in both CO conversion and O/P (C2–C4) ratio was observed on the highest K loading sample during c.a. 280 h of TOS.

Overview of DRS uncooled VOx infrared detector development (2011)

Significant progress has been made over the past decade on uncooled focal plane array technologies and production capabilities. The detector pixel dimensions have continually decreased with an increase in pixel performance making large format, high-density array products affordable. In turn, this has resulted in the proliferation of uncooled IR detectors in commercial and military markets. Presently, uncooled detectors are widely used in firefighting, surveillance, industrial process monitoring, machine vision, and medical applications. Within the military arena, uncooled detectors are ubiquitous in Army soldier systems such as weapon sights, driver's viewers, and helmet-mounted sights. Uncooled detectors are also employed in airborne and ground surveillance sensors including unmanned aerial vehicles and robot vehicles.
Analysis of P-Body Assembly inSaccharomyces cerevisiae (2007)

Recent experiments have defined cytoplasmic foci, referred to as processing bodies (P-bodies), that contain untranslating mRNAs in conjunction with proteins involved in translation repression and mRNA decapping and degradation. However, the order of protein assembly into P-bodies and the interactions that promote P-body assembly are unknown. To gain insight into how yeast P-bodies assemble, we examined the P-body accumulation of Dcp1p, Dcp2p, Edc3p, Dhh1p, Pat1p, Lsm1p, Xrn1p, Ccr4p, and Pop2p in deletion mutants lacking one or more P-body component. These experiments revealed that Dcp2p and Pat1p are required for recruitment of Dcp1p and of the Lsm1-7p complex to P-bodies, respectively. We also demonstrate that P-body assembly is redundant and no single known component of P-bodies is required for P-body assembly, although both Dcp2p and Pat1p contribute to P-body assembly. In addition, our results indicate that Pat1p can be a nuclear-cytoplasmic shuttling protein and acts early in P-body assembly. In contrast, the Lsm1-7p complex appears to primarily function in a rate limiting step after P-body assembly in triggering decapping. Taken together, these results provide insight both into the function of individual proteins involved in mRNA degradation and the mechanisms by which yeast P-bodies assemble.
53‐2: Wide‐Color‐Gamut and High‐Dynamic‐Range Color‐Image Encoding Scheme based on CIECAM02 (2016)

We propose a new image‐encoding scheme for a wide‐color‐gamut/high‐dynamic‐range display. The proposed scheme consists of two stages: color conversion from input XYZ to an opponent color space (based on CIECAM02), and high‐dynamic‐range encoding. A sub‐sampling test shows that the proposed scheme performs better than previous models.
Switch branch in trap-rich RFSOI with 84 dBm off-state IP3 (2015)

Third-order intermodulation intercept (IP3) of 90 dBm required for uplink carrier aggregation in LTE systems drives technology, modeling, design and characterization methods for Front-End semiconductor technology. For the first time, direct on-wafer switch branch IP3 of 84 dBm on trap-rich RF silicon on insulator (RFSOI) is demonstrated. Exploiting widely available low passive intermodulation (PIM) techniques, intermodulation distortion of switch branches and transmission lines is easily obtained to 10 Watts RF input power. On-wafer measurement system IP3 of 98 dBm gives visibility beyond harmonic distortion to the critical product level requirement of IP3.

Microbial Biomass and Community Composition Involved in Cycling of Organic Phosphorus in Sediments of Lake Dianchi, Southwest China (2016)

Organic phosphorus (Po) was a major fraction of phosphorus (P) in sediments of lakes, and microbes were involved in most of its relevant biogeochemical cycling. Forms and quantification of Po were investigated by sequential fractionation in 18 sediments of Lake Dianchi, Southwest China. Microbial biomass and community structure in these sediments were determined by phospholipid fatty acids (PLFAs). Distribution of Po fractions were in the rank order that humic Po > nucleic acid and polyphosphate > residual P > Ca-Al-Po > Fe-Po > sugar Po > acid soluble Po > H2O-Po. The recoveries of Po and Pi in these detailed sequential fractions including residual P shows that the total contents of Po in sediments of lakes were overestimated by the Standards, Measurements and Testing (SMT) protocol (ignition method). Microbial biomass including Gram-positive bacteria (14.4–20.0%), Gram-negative bacteria (32.7–38.4%), microeukaryotes (14.9–24.4%), aerobic bacteria (43.6–55.8%), anaerobic bacteria (0–2.9%) and type І methanotrophs (17.6–24.4%) were assigned. Microbial mass and their composition were strongly correlated with H2O-Po, Fe-Po, nucleic acid and polyphosphate, and humic Po, though residual P was likely inert for microbes in sediments. The formation and degradation of Po was closely related with microbial activities in sediments. These findings have implications for understanding the role of microbes on cycling of Po and organic matter in sediments of lakes.
Antibody-Based Assays for Phenotyping of Extracellular Vesicles (2015)

Extracellular vesicles (EVs) are a heterogeneous population of membrane-enclosed vesicles. EVs are recognized as important players in cell-to-cell communication and are described to be involved in numerous biological and pathological processes. The fact that EVs are involved in the development and progression of several diseases has formed the basis for the use of EV analysis in a clinical setting. As the interest in EVs has increased immensely, multiple techniques have been developed aiming at characterizing these vesicles. These techniques characterize different features of EVs, like the size distribution, enumeration, protein composition, and the intravesicular cargo (e.g., RNA). This review focuses on techniques that exploit the specificity and sensitivity associated with antibody-based assays to characterize the protein phenotype of EVs. The protein phenotype of EVs can provide information on the functionality of the vesicles and may be used for identification of disease-related biomarkers. Thus, protein profiling of EVs holds great diagnostic and prognostic potential.
A New Technique for Simultaneous Assay of Biogenic Amines and Their Metabolites in Unpurified Mouse Brain (1982)

Abstract We developed a chromatographic system which separates cate-cholamines and indolamines as well as a large number of their metabolites (acids, aminoacids and glycols). Waters Radial Pak columns compressed radially to avoid formation of cavities in the packing, were used. These columns must be washed with methanol in order to obtain reproducible results when an ion-pairing mobile phase is employed. The conditioning of bhe columns was not affected by washing with triethylamine or variations in radial pressure. Good resolution of 13 samples was obtained in 28 minutes with a mobile phase composed of 0.1 M KH2PO4, 0.1 mM EDTA and 5 mM heptane sulfonic acid in water and Me OH (85:15), pH = 3.6. Products were identified with the use of a Metrohm 64l electrochemical detector. The technique was used for rapid, simultaneous determination of NA, DA, DOPAC, HVA, 5HT and 5HIAA in deproteinated mouse brain samples.
Tracing of state machine execution in the model-driven development framework (2010)

Framework for eXecutable UML (FXU) supports a model-driven approach for creation of reliable applications in C#. Basing on UML classes and their state machines, a source code is generated and executed using a run-time library. All modeling concepts of UML behavioral state machines can be used in the FXU. Tracing of program execution in terms of elements of origin state machines assists program comprehension and verification. This paper presents a new component of the framework for observing traces of program execution. The state machine tracing improved model-driven engineering of an application in comparison to the direct analysis of textual logs generated during the program execution. We discuss system requirements, steps of tracing process and advantages and disadvantages of the solution. The approach was applied in the development of an application simulating a presence server for the status service of a social network model.
