A NEW ILEOSTOMY-COLOSTOMY DEVICE WITH A DISPOSABLE PLASTIC BAG AND NO CEMENT (1954)

Surgical techniques in performing ileostomy and colostomy have advanced in recent years, but little change has been made in the design of devices for the postoperative comfort of patients undergoing these operations. There are several features that any device should have for collecting the fecal stream from an ileostomy or colostomy stoma. They are: 1. The device should be easily applied. 2. It should be light in weight. 3. It should not be bulky enough to distort the body contour or bulge through clothing. 4. It should be odorless. 5. It should have no irritating properties to macerate or irritate the skin of the abdomen around the ileostomy or colostomy stoma. 6. It should be easy to empty or dispose. These ideal features have been only partially met by the popular rubber-type commercial ileostomy and colostomy bags, and a continuing search is being made to develop an ideal device. The
Effect of light-beam deviation on the instrument matrix of the four-detector photopolarimeter (1997)

Analytical geometry, ray tracing, and the Mueller-matrix calculus are used to determine the calibration matrix of the four-detector photopolarimeter (FDP) when the incident light beam deviates from the optical axis of the instrument. Detectors of the FDP are represented by their surface equations in Cartesian coordinates. The instrument matrices corresponding to angular deviations of ±0.5 and ±1.0 deg in reference horizontal and vertical planes, and their differences from the unperturbed matrix are given for two FDP configurations. Output Stokes parameters that correspond to several typical input states of polarization are calculated to demonstrate the effects of light-beam deviation.
Light Emission from Silicon-based Nano-materials (2006)

This paper presents an overview of the research activities aimed at engineering novel, nanostructured-based materials solutions for CMOS-compatible electrically driven light sources. In particular, the state of the art of the optical and electrical properties of Si-nc nucleated within Si-rich nitride (SRN) matrices, and their large potential for energy sensitized, efficient 1.55mum electroluminescence under low injection fields are discussed
A Sensitive Electrochemical Protein Quantification Method (2000)

This article presents a sensitive electrochemical method for the quantification of proteins. The assay used the biuret reaction, which is based on the complexation of proteins with copper ions to form a copper-protein complex. In the present approach, once copper ions were complexed with the protein, they were released by an acidic treatment and simultaneously separated by ultracentrifugation from the protein sample. This allowed differential pulse anodic stripping voltammetry (DPASV) of Cu2+ on carbon rotogravure printed electrodes (CARPEs). A nM detection limit for bovine serum albumin (BSA) was found with this method. The kinetics of this assay were tested and it resulted that the total assay can be carried out in 27 min, including incubation, washing steps and detection.
p75 neurotrophin receptor functions as a survival receptor in brain‐metastatic melanoma cells (2003)

The p75 neurotrophin receptor (p75(NTR)), a common receptor for members of the neurotrophins (NT) family, was previously identified as a molecular determinant of brain metastasis. We have also reported that NT treatment of murine and human brain-metastatic melanoma cells affects their invasive capacities and increases the production of heparanase, an important and unique extracellular matrix (ECM) degradative enzyme. Neurotrophism can be a survival-support mechanism for brain-metastatic cells and a survival assay was devised to mimic the growth limiting conditions of rapidly expanding metastatic tumors prior to neoangiogenesis. We report that p75(NTR) promoted the survival of brain-metastatic melanoma cells but not melanocytes in stress cultures conditions. Secondly, melanoma cells fluorescently sorted for high p75(NTR) expression (p75(NTR-H) cells) had an up to a 15-fold greater survival than those sorted for low p75(NTR) expression (p75(NTR-L) cells). Thirdly, cells overexpressing p75(NTR) associated with the growth fraction and provided these cells with an inherent growth advantage. Finally, we observed an increased survival of sorted p75(NTR-L) cells, dependent upon treatment of NT members whose functional receptors are present on these cells. Together, these results delineate that p75(NTR)-mediated trophic support profoundly affects competitive melanoma-cell survival when the tumor cell microenvironment becomes growth limiting.
Anticollusion watermarking of 3D meshes by prewarping (2008)

A novel pre-warping technique for 3D meshes is presented to prevent collusion attacks on fingerprinted 3D models. By extending a similar technique originally proposed for still images, the surface of watermarked 3D meshes is randomly and imperceptibly pre-distorted to protect embedded fingerprints against collusion attacks. The peculiar problems set by the 3D nature of the data are investigated and solved by preserving the perceptual quality of warped meshes. The proposed approach is independent of the chosen fingerprinting system. The proposed algorithm can be implemented inside a watermarking chain, as an independent block, before performing features extraction and watermark embedding. It follows that the detection algorithm is not influenced by the anti-collusion block. The application of different collusion strategies has revealed the dificulty for colluders to inhibit watermark detection while ensuring an acceptable quality of the attacked model.
Chirality‐Dependent Reactivity of Individual Single‐Walled Carbon Nanotubes (2013)

Electronic characteristics of a single-walled carbon nanotube (SWCNT) strongly depend on minor variations in its atomic arrangement, specifically chirality. Therefore, precise control over nanotube chirality is highly desired for their application. Theoretically, SWCNTs with different structures have different chemical reactivities, which can be further used for their chirality selection. Here, an approach is developed to examine the relationship between the chirality of SWCNTs and their intrinsic chemical reactivity. By oxidizing individual, high-quality, suspended SWCNTs and using the nanobeam electron diffraction technique, it is shown that the reactivity of SWCNTs to O2 is intricately related to their diameters, metallicity, and chiral angles. In particular, even minor differences in chiral angles lead to big differences in their reactivity, which concords with first-principles calculations. Based on the experimental observations, a chirality-dependent reactivity sequence is constructed for SWCNTs. These findings shed light on effective chiral separation of SWCNTs for their practical application in many fields.
DEVELOPMENT OF ANGLE PLY CEMENT BASED COMPOSITE LAMINATES (1998)

Novel cement based materials with improved structural and mechanical properties are developed. High fiber content cementitious laminates are manufactured using a computer controlled closed loop system for filament winding. Continuous fiber cement based composites consisting of unidirectional lamina, [0/90/0], and [0,+45n,+90n] are manufactured using Alkali resistant glass fibers. Mechanical properties of the composites are measured using uniaxial tensile specimen. Test results indicate that the tensile strength of unidirectional fibers is as much as 50 MPa. In the case of cross ply laminates, various mechanisms of ply delamination and crack deflection increase the strain capacity to the order of 2%. In addition, fracture toughness as much as two orders of magnitude higher than the conventional FRC materials is obtained. The extent of matrix cracking, ply delamination, and crack deflection mechanisms are studied by means of fluorescent microscopy.
Bridging the gap between feedstock growers and users: the study of a coppice poplar-based biorefinery (2018)

We propose a business model based on the integration of the plantation and the biorefinery. In this model, different feedstocks are assessed using a metric of product tonnage per unit land per year. Use of this new economic metric bridges the gap between feedstock growers and users to maximize the overall production efficiency.
Towards Context Awareness Using Symbol Clustering Map (2003)

Recognizing the context of use is important in making mobile devices simple to use. The device and the underlying mobile service can provide a personalized user interface that adapts to the usage situation. The device can infer parts of the context of the user from features extracted from on-board measurements of acceleration, noise level, luminosity, humidity, etc. In this paper we consider context recognition by fusing and clustering these context features using a recently introduced method, the Symbol Clustering Map. As such, it can be used for finding static patterns but a suitable transformation of the data allows identifying also temporal patterns.
Exploration of Matrix Effects in Laser Ablation Inductively Coupled Plasma Mass Spectrometry Imaging of Cisplatin-Treated Tumors (2020)

The use of a low aerosol dispersion ablation chamber within a laser ablation inductively coupled plasma mass spectrometer (LA-ICP-MS) setup allows for high-resolution, high-speed imaging of the distribution of elements within a sample. Here we show how this enhanced capability creates new analytical problems and solutions. We report the distribution of platinum at the cellular level in non-small cell lung cancer (NSCLC) explant models after treatment with clinically relevant doses of cisplatin. This revealed for the first time a correlation between the platinum signal and the presence of carbon deposits within lung tissue. We show how complementary ion beam analysis techniques, particle-induced X-ray emission (PIXE) and elastic backscattering spectrometry (EBS), can be used to explore potential matrix effects in LA-ICP-MS data. For these samples, it was confirmed that the enhancement was unlikely to have resulted from a matrix effect alone. Thus, the presence of carbon deposits within tissue has potential implications for the effective distribution of the cisplatin drug.
Catalytic Activity of Ag/SiO 2 and Ag/Co 3 O 4 Hierarchically Porous Monoliths for Hydrogenation of Dyes (2014)

In this work, the synthesis of silver (Ag) supported on hierarchically porous silica (SiO&lt;sub&gt;2&lt;/sub&gt;), and cobalt oxide (Co&lt;sub&gt;3&lt;/sub&gt;O&lt;sub&gt;4&lt;/sub&gt;) monoliths and the catalytic activity of these monoliths for the hydrogenation of methylene blue (MB) and methyl orange (MO) dyes in water is reported. The SiO&lt;sub&gt;2&lt;/sub&gt; monoliths were synthesized using a sol-gel technique. The Co&lt;sub&gt;3&lt;/sub&gt;O&lt;sub&gt;4&lt;/sub&gt; monoliths were prepared by nanocasting, using the SiO&lt;sub&gt;2&lt;/sub&gt; monoliths as template. Loading of Ag nanoparticles on the SiO&lt;sub&gt;2&lt;/sub&gt; and Co&lt;sub&gt;3&lt;/sub&gt;O&lt;sub&gt;4&lt;/sub&gt; monoliths, was done by a solution infiltration method using aqueous silver nitrate (AgNO&lt;sub&gt;3&lt;/sub&gt;) solution followed by reduction with ethylene glycol. The resulting monoliths were characterized by XRD, BET-SA, and SEM, and the catalytic activity of the monoliths was studied for the hydrogenation of MB and MO by sodium borohydride (NaBH&lt;sub&gt;4&lt;/sub&gt;). Careful control experiments allowed the overall rate of the Ag catalyzed reaction to be corrected for the rates of the non-catalyzed reaction and the rates of dye adsorption on the supports and Ag nanoparticles. Ag supported on SiO&lt;sub&gt;2&lt;/sub&gt; gave the fastest hydrogenation for MB, Ag on Co&lt;sub&gt;3&lt;/sub&gt;O&lt;sub&gt;4&lt;/sub&gt; gave the fastest MO hydrogenation.
Hardware-controlled prefetching in directory-based cache coherent systems (2002)

Sequential consistency is the popular accepted criterion of correct execution in shared-memory multiprocessors. Typical implementation of sequential consistency requires each access to be delayed until the previous access in the same process completes. This is detrimental to performance. Prefetching is an effective way of overlapping the execution of memory accesses. This paper studies hardware-controlled prefetching in a directory-based cache coherent system, and proposes a new prefetching scheme as an improvement on the normal scheme. Besides, a cycle-by-cycle trace-driven simulation model is built to evaluate these prefetching schemes. Simulation results show that prefetching is effective in improving performance, and the new prefetching scheme we proposed can improve performance further.
[Adhesion and aggregation of neutrophils in patients with unstable angina]. (1995)

The adherence and aggregation abilities of neutrophils (PMNs) were evaluated in thirty three patients with unstable angina, who were qualified for PTCA procedure. The control group consisted of forty one clinically healthy persons. The blood for investigations was obtained from coronary sinus and basilic vein just before the procedure, while in the control group from basilic vein only. The adherence of PMNs to plastic surface (rest and stimulated by PMA) was estimated in vitro according to Oez's et al. method by measuring optical density of generated formazan, whereas the aggregation of PMNs was evaluated using the leukergy test according to the method of Fleck in Berliner's and Aronson's modification. In patients with unstable angina statistically significant higher (p < 0.001) adherence of peripheral blood PMNs, compared with control groups was found (patients: rest-0.525 +/- 0.245, stimulated-0.839 +/- 0.419, control group: rest-0.260 +/- 0.129, stimulated-0.522 +/- 0.377). The aggregation of peripheral blood PMNs was significantly higher (p < 0.05) in the sick than in the control group (the sick-10.98 +/- 4.29%, controls-4.65 +/- 3.01%). No differences in investigated parameters of PMNs obtained from peripheral or coronary sinus blood were found.
Single cells in confined volumes: microchambers and microdroplets (2015)

Microfluidic devices capable of manipulating and guiding small fluid volumes open new methodical approaches in the fields of biology, pharmacy, and medicine. They have already proven their extraordinary value for cell analysis. The emergence of microfluidic platforms has paved the way to novel analytical strategies for the positioning, treatment and observation of living cells, for the creation of chemically defined liquid environments, and for tailoring biomechanical or physical conditions in small volumes. In this article, we particularly focus on two complementary approaches: (i) the isolation of cells in small chambers defined by microchannels and integrated valves and (ii) the encapsulation of cells in microdroplets. We review the advantages and limitations of both approaches and discuss their potential for single-cell analysis and related fields. Our intention is also to give a recommendation on which platform is most appropriate for a new question, i.e., a guideline to choose the most suitable platform.
Remote GPU-Accelerated Online Pre-processing of Raster Maps for Terrain Rendering (2012)

We present a distributed architecture for accelerated pre-processing of remote sensing data for immediate terrain visualization. Interactive 3D visualization approaches for large terrain datasets employ level of detail techniques that require a multi-resolution data representation. The high computational cost of constructing these representations is often not viewed as a major drawback, as it is considered an o-line pre-processing step. This prevents the application of existing methods in the case of changing data, which is becoming increasingly important for a multitude of applications where datasets are being generated, transmitted and must be visualized immediately, such as in disaster management.&#13;\nOur system uses graphics processing units (GPUs) to accelerate the process of generating a multi-resolution representation, achieving sucient performance to enable on-line visualization on a front-end workstation communicating with a back-end cluster of machines equipped with GPUs. As a reference data structure, we use a quad tree decomposition of the so-called HEALPix sphere parameterization, which is well-suited for spherical terrain rendering. Our system correctly handles overlapping and unregistered mixed-resolution datasets. We demonstrate the ecacy of our approach by applying it to the surface of Mars using both the NASA Mars Orbiter Laser Altimeter and the ESA Mars Express High Resolution Stereo Camera datasets.

Therapeutic targeting of bile acids (2015)

The first objectives of this article are to review the structure, chemistry, and physiology of bile acids and the types of bile acid malabsorption observed in clinical practice. The second major theme addresses the classical or known properties of bile acids, such as the role of bile acid sequestration in the treatment of hyperlipidemia; the use of ursodeoxycholic acid in therapeutics, from traditional oriental medicine to being, until recently, the drug of choice in cholestatic liver diseases; and the potential for normalizing diverse bowel dysfunctions in irritable bowel syndrome, either by sequestering intraluminal bile acids for diarrhea or by delivering more bile acids to the colon to relieve constipation. The final objective addresses novel concepts and therapeutic opportunities such as the interaction of bile acids and the microbiome to control colonic infections, as in Clostridium difficile-associated colitis, and bile acid targeting of the farnesoid X receptor and G protein-coupled bile acid receptor 1 with consequent effects on energy expenditure, fat metabolism, and glycemic control.

Two Cardiovascular Risk Factors in One? Homocysteine and Its Relation to Glomerular Filtration Rate (2008)

Homocysteine plasma levels significantly depend on renal function. This correlation is even more robust when GFR is measured using clearance methods. Therefore, in order to assess whether homocysteine is an independent cardiovascular risk factor, accurate adjustments for renal dysfunction are essential.
Intrauterine transmission of hepatitis B virus is closely related to placental leakage (1987)

Hepatitis B virus (HBV), transmitted by hepatitis B e antigen (HBeAg)-positive mothers by intrauterine infection, infecting newborns, is closely related to signs and symptoms associated with miscarriage. However, no correlation was observed between intrauterine infection of infants and the presence of antibodies of immunoglobulin M (IgM) class antibodies against hepatitis B core antigen (anti-HBc) in maternal blood, nor was HBeAg found in maternal or cord sera. These results indicate that contamination by the mother's blood, through placental leakage, plays an important role in HBV infection in utero. Without placental leakage, maternal blood could not pass through the placenta and enter fetal circulation, and so intrauterine infection would not occur, even if very high titers of hepatitis B surface antigen (HBsAg) and HBeAg were present in maternal blood.
Analysis of gravity-induced particle motion and fluid perfusion flow in the NASA-designed rotating zero-head-space tissue culture vessel (1991)

The gravity induced motions, through the culture media, is calculated of living tissue segments cultured in the NASA rotating zero head space culture vessels. This is then compared with the media perfusion speed which is independent of gravity. The results may be interpreted as a change in the physical environment which will occur by operating the NASA tissue culture systems in actual microgravity (versus unit gravity). The equations governing particle motions which induce flows at the surface of tissues contain g terms. This allows calculation of the fluid flow speed, with respect to a cultured particle, as a function of the external gravitational field strength. The analysis is approached from a flow field perspective. Flow is proportional to the shear exerted on a structure which maintains position within the field. The equations are solved for the deviation of a particle from its original position in a circular streamline as a function of time. The radial deviation is important for defining the operating limits and dimensions of the vessel because of the finite radius at which particles necessarily intercept the wall. This analysis uses a rotating reference frame concept.

Ambulatory Versus Casual Blood Pressure in the Diagnosis of Hypertensive Patients (1985)

Recent advances in medical technology have enabled the development of fully automatic portable noninvasive blood pressure recorders which can reliably monitor changes of blood pressure over periods of 24 hour or more. The commercial availability of such recorders raises the question of their relevance to the practical management of hypertensive patients.The rationale for the use of Ambulatory Blood Pressure monitoring (ABPM) is the enormous variability of blood pressure. This has been amply demonstrated with both invasive and noninvasive ABPM, and is not a matter of dispute (1,2). Since the adverse effects of blood pressure on the circulation are thought to depend either on the average level of pressure over time or possibly also on the peak levels of pressure, there is a sound theoretical reason for thinking that multiple measurementspage missing 258-258
