Oral Activated Charcoal in Patients with Uremic Pruritus (1995)

Twenty-three chronic uremic patients on maintenance hemodialysis and suffering from severe pruritus were treated with activated powdered charcoal (6 g daily p.o.). In 10 patients pruritus disappeared completely, and in 10 other patients a partial effect was observed. The favorable results persisted for several weeks after discontinuation of the treatment. Only 3 cases were totally unresponsive. No relevant undesirable side effects were observed with the exception of 1 case who showed treatment intolerance. It is concluded that activated charcoal per os is a safe, effective, and low-cost therapy for patients with uremic pruritus, but its mechanism of action is unknown.
Two Types of Natural Graphite Host Matrix for Composite Activated Carbon Adsorbents (2010)

Two types of host for activated carbon (AC) adsorbents intended for use in compressed systems are studied: expanded natural graphite (ENG) and expanded natural graphite treated with acid (ENG-TA). Results show that compressed ENG-TA has much higher thermal conductivity than the compressed ENG. For a density of 830 kg/m3 the thermal conductivity of compressed ENG-TA is 336 W/(mK), and it is of the order of one hundred times higher compared with compressed ENG having similar density. The permeability of compressed ENG-TA is much more critical than the compressed ENG. For example for similar density of 300 kg/m3, the permeability of compressed ENG-TA is 2.01 × 10−15 m2 while the permeability of compressed ENG is 1.07 × 10−13 m2. Compressed composite adsorbents of AC with ENG as host were produced with a high density in the range 700–720 kg/m3. Considering that the permeability will be too low using composite AC with ENG-TA as host in high density, the density range was restricted to less than 500 kg/m3. The thermal conductivity of AC/ENG-TA composite is much higher than the thermal conductivity of AC/ENG composite, and it is about 7 times higher than the optimal value of AC/ENG composite.

The First Tri- and Tetraalkoxysilanes with Four Different Substituents (1997)

Unsymmetrically substituted tri- and tetraalkoxysilanes were surprisingly found to be configurationally stable and easy to prepare. It was found that compounds of type MeSi(OR)(2)(OR'), MeSi(OR)(OR')(OR"), Si(OR)(2)(OR')(2), Si(OR)(2)(OR')(OR"), Si(OR)(3)(OR'), and even Si(OR)(OR')(OR")(OR) could be obtained by sequential addition of a variety of chiral and achiral alcohols to methyltrichlorosilane or tetrachlorosilane in the presence of pyridine. In the case of MeSi(OR)(OR')(OR") and Si(OR)(OR')(OR")(OR), two types of compounds that have never been prepared before, were obtained in good yield.
Functions of milk protein gene 5′ flanking regions on human growth hormone gene (1994)

Abstract Fragments containing 5′ flanking regions of four bovine milk protein genes—alpha lactalbumin (bαLA), alpha S 1 casein (bαS 1 CN), beta casein (bβCN), kappa casein (b k CN)—and mouse whey acidic protein (mWAP) gene were prepared by PCR and ligated to human growth hormone (hGH) gene. These recombinant DNAs were microinjected into rat embryos to produce transgenic rats, and the functions of the 5′ regions to direct secretion of hGH in the milk were tested. Although milk was obtained only in 5 of 19 mWAP/hGH rat lines, more than two‐thirds of the rats carrying the other four DNAs produced milk. More than 80% of the lactated rats carrying bαLA/, bβCN/, and mWAP/hGH, and 33% of the laclated bαS 1 CN/hGH rats secreted detectable amounts of hGH (> 0.05 μg/ml) in the milk. In some rats, the hGH concentrations in the milk were comparable to or more than that of the corresponding milk protein in bovine milk. The ranges of hGH concentrations in the milk of bαLA/, bβCN/, bαS 1 CN/, and mWAP/hGH rats were 1.13–4,360 μg/ml, 0.11–10,900 μg/ml, 86.8–6,480 μg/ml, and 6.87–151 μg/ml, respectively. HGH was also detected in the sera of these rats, and some abnormalities of growth and reproduction were observed. All but one virgin mWAP/hGH rat secreted up to 0.0722 μg/ml of hGH in the serum, and more than half of them showed abnormal fat accumulations at their abdomen. None of the bαCN/hGH rats secreted detectable amount of hGH into their milk, whereas 8 of the 11 lines secreted hGH into their sera. For the production of hGH in transgenic rat milk, the 5′ region of bαS 1 CN was shown most suitable, because the bαS 1 CN/hGH rat secreted > 6,000 μg/ml of hGH into the milk and could be reproduced. © 1994 Wiley‐Liss, Inc.
Resonantly Enhanced Nonlinearity in Doped Fibers for Low-Power All-Optical Switching: A Review (1997)

This paper reviews the state of research in resonantly enhanced nonlinearities in fibers doped with an absorber, of interest for low-power all-optical switching. A mathematical model is first presented which shows that this type of nonlinearity can be up to nearly a billion times stronger than the intrinsic Kerr effect of silica. In principle, it can induce a phase modulation of π in the infrared in a subnanometer length of fiber with just a few milliwatts of pump power, with a response time in the nanosecond range. Much shorter response times (picosecond or less) are also possible at the expense of a concomitantly higher switching peak power, although the switching energy remains the same, in the 10-pJ range. The experimental investigations conducted so far with rare earths (Er3+, Nd3+, Yb3+, and Sm3+), color centers (POHC), and transition metal ions (vanadium) are reviewed. They show that a wide range of performance is possible, from 50-μW switching power and 10-ms response (in Er3+grating) to 6-W switching peak power and a response under 25 ns (with POHC). With some of the dopants tested to date, it is readily possible to fabricate fiber switches only 1 cm in length, with a switching power of 15 mW and a 2- to 5-μs response time.
Autonomous Self-Backhauled LTE Mesh Network With QoS Guarantee (2018)

Public safety communication systems are currently evolving due to emergence of long term evolution (LTE) as a mature solution to replace the legacy ones while providing new services. However, LTE is initially designed for commercial cellular network and needs to be furthermore evolved to tackle the substantial requirements of public safety use cases. For instance, opportunistic deployments require modifications to enable the autonomous operation and meshing of moving base stations while satisfying heterogeneous frequency band availability. In this article, we present a novel radio access network infrastructure architecture that enables multi-hop LTE mesh networking for nomadic and autonomous base stations via in-band self-backhauling. Furthermore, we investigate the coordination and orchestration functionality within the proposed architecture and propose a hierarchical resource scheduling algorithm in order to efficiently meet quality of service (QoS) requirements for real-time traffic while maximizing the throughput for elastic flows. To demonstrate the feasibility and reliability of our proposed architecture, we implement the corresponding self-backhauling air-interface based on OpenAirInterface platform and compare it with the legacy LTE air-interface. Finally, we evaluate the efficiency and adaptability of our proposed resource scheduling algorithm in various network topology and heterogeneous traffic flows with QoS requirements.

Migraine photophobia originating in cone-driven retinal pathways (2016)

Migraine headache is uniquely exacerbated by light. Using psychophysical assessments in patients with normal eyesight we found that green light exacerbates migraine headache significantly less than white, blue, amber or red lights. To delineate mechanisms, we used electroretinography and visual evoked potential recording in patients, and multi-unit recording of dura- and light-sensitive thalamic neurons in rats to show that green activates cone-driven retinal pathways to a lesser extent than white, blue and red; that thalamic neurons are most responsive to blue and least responsive to green; and that cortical responses to green are significantly smaller than those generated by blue, amber and red lights. These findings suggest that patients' experience with colour and migraine photophobia could originate in cone-driven retinal pathways, fine-tuned in relay thalamic neurons outside the main visual pathway, and preserved by the cortex. Additionally, the findings provide substrate for the soothing effects of green light.

A compliant and biomimetic three-layered vascular graft for small blood vessels (2017)

Engineering a small diameter vascular graft with mechanical and biological properties comparable to living tissues remains challenging. Often, current devices lead to thrombosis and unsatisfactory long-term patency as a result of poor blood compatibility and a mismatch between the mechanical properties of the living tissue and the implanted biomaterial. Addressing all these requirements is essential to produce scaffolds able to survive throughout the life of the patient. For this purpose, we fabricated a novel three-layered vascular graft by combining electrospinning and braiding. Mirroring the structure of human blood vessels, the proposed device is composed of three layers: the intima, the media, and the adventitia. The intima and media layers were obtained by sequentially electrospinning silk fibroin (SF) and poly(L-lactide-co-ε-caprolactone), with ratios selected to match the mechanical properties of the native tissue. For the outer layer, the adventitia, SF yarns were braided on top of the electrospun tubes to create a structure able to withstand high pressures. Compliance, Young's modulus and deformability of the obtained scaffold were similar to that of human blood vessels. Additionally, cytocompatibility of the two layers, media and intima, was assessed in vitro by analysing cell metabolic activity and proliferation of endothelial cells and smooth muscle cells, respectively. Furthermore, heparin functionalization of the scaffolds led to improved anticoagulant properties upon incubation in whole blood. The obtained results indicate a potential application of the herewith designed three-layered construct as a vascular graft for small diameter blood vessel engineering.
Oxyhydrides of (Ca,Sr,Ba)TiO<sub>3</sub> Perovskite Solid Solutions (2012)

The oxyhydride solid solutions (Ca,Sr)TiO(3-x)H(x) and (Sr,Ba)TiO(3-x)H(x) have been prepared by reducing the corresponding ATiO(3) oxides with calcium hydride. Under the reaction conditions examined, a hydride content of x = 0.1-0.3 was obtained for all compositions. Compared to our previous result with BaTiO(3-x)H(x), the larger particle size in this study (20-30 μm vs 170 nm) resulted in a somewhat lower hydride amount despite prolonged reaction times. We examined changes in cell volume, octahedral tilt angle, and site occupancy of different anion sites after conversion to oxyhydrides; it appears that these oxyhydrides fit the geometrical descriptions typical for regular ABO(3) perovskites quite well. The hydrogen release temperature, previously shown to be indicative of the hydride exchange temperature, however, does not scale linearly with the A-site composition, indicating a potential effect of chemical randomness.
Coronary Hemodynamic Effects of Increasing Ventricular Rate in the Unanesthetized Dog (1968)

In five unanesthetized dogs with surgical heart block, increasing ventricular rate from 50--75 to 250--300 beats/min demonstrated an optimum ventricular rate of 130 to 185, above which aortic pressure and cardiac output fell. In contrast, coronary blood flow continued to rise to a ventricular rate of 250 to 300 beats/min. Stroke systolic coronary flow was well maintained over the entire range of ventricular rates studied, while stroke diastolic coronary flow fell with an increase of ventricular rate. A reactive hyperemic response following release of a 1- to 10-second coronary artery occlusion at a ventricular rate of 250 to 300 suggests that the fall in aortic pressure and cardiac output which occurred at these rates may not be due to an insufficiency of total coronary blood flow. Beta-receptor activity did not appear to play a significant role in the hemodynamic adjustment to increases in ventricular rate within the optimum range for cardiac output and aortic pressure from 52--77 to 115--156 beats/min.
Recognition of Multi Axis Milling Features: Part I-Topological and Geometric Characteristics (2004)

Most of the work in machining feature recognition has been limited to 2-1/2 and 3 axis milling features. The major impediment to recognition of complex features has been the difficulty in generalizing the characteristics of their shape. This two-part paper describes general purpose methods for recognizing both simple and complex features; the latter may have freeform surfaces and may require 4 or 5 axis machining. Part I of this paper attempts to describe features in terms of geometric and topological characteristics. Part II of the paper uses the characterization and classification developed in Part I for designing feature recognition algorithms. Part I proposes five basic categories and several sub-classifications of features derived both from machining considerations and computational methods for NC toolpath generation. Rather than using topologically rigid features, such as slots and steps, etc., machining features are classified as “Cut-Thru,” “Cut-Around” and “Cut-on” and further classified into sub-categories. Each feature class is described by a list of properties. Apart from the obvious use in feature recognition, this feature classification and characterization may have potential use in developing future data exchange standards for complex features.
Epistatic and independent functions of Caspase-3 and Bcl-X <sub>L</sub> in developmental programmed cell death (2000)

The number of neurons in the mammalian brain is determined by a balance between cell proliferation and programmed cell death. Recent studies indicated that Bcl-X(L) prevents, whereas Caspase-3 mediates, cell death in the developing nervous system, but whether Bcl-X(L) directly blocks the apoptotic function of Caspase-3 in vivo is not known. To examine this question, we generated bcl-x/caspase-3 double mutants and found that caspase-3 deficiency abrogated the increased apoptosis of postmitotic neurons but not the increased hematopoietic cell death and embryonic lethality caused by the bcl-x mutation. In contrast, caspase-3, but not bcl-x, deficiency changed the normal incidence of neuronal progenitor cell apoptosis, consistent with the lack of expression of Bcl-X(L) in the proliferative population of the embryonic cortex. Thus, although Caspase-3 is epistatically downstream to Bcl-X(L) in postmitotic neurons, it independently regulates apoptosis of neuronal founder cells. Taken together, these results establish a role of programmed cell death in regulating the size of progenitor population in the central nervous system, a function that is distinct from the classic role of cell death in matching postmitotic neuronal population with postsynaptic targets.

Large scale fuzzy multiobjective 0-1 programs through genetic algorithms with decomposition procedures (2002)

In this paper, we focus on large scale fuzzy multiobjective 0-1 programming problems. For fuzzy multiobjective programming problems, we introduce extended concepts of the ordinary Pareto optimal solution. The problem to find a satisfying solution for the decision-maker from the extended Pareto optimal solution set is a kind of combinatorial optimization problem, so we apply genetic algorithms to solve it. Since the problems considered in this paper are large scale and a large scale problem has often a special structure called block angular structure, we apply genetic algorithms revised by the authors to utilize the special structure.
