Does Control of Diabetes Prevent Vascular Complications? (1989)

<h3>To the Editor. —</h3> The last part of the conclusion reached by Abbott et al<sup>1</sup>concerning the impact of diabetes on survival following myocardial infarction warrants closer scrutiny. They state, in the abstract: "We conclude... in addition, when cardiac failure appears, control of diabetes assumes added importance, particularly in women, where its effect on survivorship is considerable." The data presented in this communication do not address this issue nor support this statement. While it would be nice to believe that control of diabetes once congestive heart failure supervenes after a myocardial infarction prolongs survival, I am unaware of evidence that supports this theory. Indeed, studies are now ongoing to determine whether control of diabetes can delay or ameliorate the long-term vascular complications of the disease. A second concern is the comment by the authors that diabetes in women also seems to be more severe because a greater percentage of
Synthesis, characterization and crystal structures of two alkaline-earth metal complexes of olsalazine (2008)

Two one-dimensional linear coordination polymers, [Mg(L) · 4(H2O)] (H2L = olsalazine) and 2 [Ca(L) · 4(H2O)] were obtained from self-assembly of CaCl2 or MgSO4 with olsalazine and their structures determined by single crystal X-ray diffraction. Both complexes are one-dimensional polymers, for complex 1 with crystal data: P2(1)/c, a = 9.5224(18), b = 11.309(2), c = 16.211(3) Å, β = 106.648(3)°, V = 1672.6(6) Å3, Z = 4, R 1 = 0.0695, wR 2 = 0.2183, for complex 2 with crystal data: P4(3)2(1)2, a = 10.4006(2), b = 10.4006(2), c = 32.0746(10) Å, V = 3469.59(14) Å3, Z = 8, R 1 = 0.0332, wR 2 = 0.1015. In the complexes, Mg and Ca adopt totally different coordination modes. Alkaline-earth Mg is six-coordinate octahedronal geometry, however, in 2, the local coordination geometry around calcium atom can be best described as a slightly distorted pentagonal bipyramid crystallizing in a homo-chiral space group. Olsalazine in both compounds also adopts dissimilar coordination modes.
Fungicide Injection to Control Dutch Elm Disease: Understanding the Options (1999)

In some situations, injecting trees with fungicides is an effective treatment for the management of Dutch elm disease (DED). Several injection products are on the market, and various means of application are recommended. Each product and method has pros and cons. The “best” product depends on the individual tree— its current condition, the objectives of the treatment, and the resources available. The purpose of this article is to bring the options and documentation together into one package, so that you can make an informed decision on what you will recommend for injection.
Methodological Analysis of Immunocytochemical Screening for Disseminated Epithelial Tumor Cells in Bone Marrow (1994)

The emerging clinical relevance of bone marrow micrometastasis has prompted several investigations, using a variety of immunocytochemical approaches. The present study was designed to evaluate some of the variables affecting the immunocytochemical detection of individual epithelial tumor cells in bone marrow. Using an alkaline phosphatase-antialkaline phosphatase staining technique, we evaluated bone marrow aspirates from 358 patients with primary carcinomas of the breast (n = 150), lung (n = 66), prostate (n = 42), or colorectum (n = 100). Individual tumor cells in cytological preparations were detected with monoclonal antibody (MAb) CK2 to the epithelial cytokeratin component 18 (CK18), which has been validated in extensive clinical studies. In addition, the utility of the broad-spectrum MAb A45-B/B3 was explored in this study. The high specificity of MAbs CK2 and A45-B/B3 was supported by analysis of bone marrow from 75 noncarcinoma control patients and by double-marker analysis with MAbs to mesenchymal marker proteins (CD45 and vimentin). In contrast, MAbs E29 and HMFG1, directed to mucin-like epithelial membrane proteins, cross-reacted with hematopoietic cells in 26.7-42.7% of all samples tested. The majority of the 154 positive samples (43.0%) from cancer patients displayed less than 10 CK18-positive cells per 8 x 10(5) marrow cells analyzed. The detection rate, however, was affected by blood contamination of the aspirate, the number of aspirates analyzed, and the number of marrow cells screened per aspiration site. Comparative immunostaining of bone marrow specimens with MAbs CK2 and A45-B/B3 indicated that downregulation of CK18 in micrometastatic carcinoma cells occurs in about 50% of the 172 samples analyzed, regardless of the primary tumor origin.(ABSTRACT TRUNCATED AT 250 WORDS)
Preliminary Study on Wireless Home Automation Systems with Both Cloud-Based Mode and Stand-Alone Mode (2014)

As the Smart Home segment is an intersection of numerous industries including consumer electronics, telecom, internet, and building automation, a Home Automation (HA) system requires flexible wireless communication architecture to not only take the advantages of wireless technologies such as reduced cost of installation and maintenance and improved user experiences but also fulfill the concerns of various industrial stakeholders. From this point-of-view, neither the pure Cloud-Based nor the Stand-Alone architecture is sufficient. In this paper, an IP-based hybrid architecture is presented which can support flexible combination of Could-Based Mode and Stand-Alone Mode. Preliminary prototyping based on the 6LoWPAN and experimental evaluation of performances have indicated the technical feasibility as well as future directions of improvement.

Cloning and Targeted Gene Disruption of<i>XYL1,</i>a<i>β</i>1,4-Xylanase Gene from the Maize Pathogen<i>Cochliobolus carbonum</i> (1993)

The gene, XYL1, encoding the major extracellular endo-beta 1,4-xylanase from the maize pathogen Cochliobolus carbonum was cloned using a synthetic, degenerate oligonucleotide based on a tryptic fragment from the purified enzyme. The deduced product of XYL1 has a M(r) of 20,869 and a predicted pI of 9.1, in good agreement with the measured M(r) and pI of the purified enzyme. The XYL1 product has strong amino acid identity to seven endo-beta 1,4-xylanases from six prokaryotes but no obvious similarity to 10 other prokaryotic endoxylanases or a yeast endoxylanase. An internal fragment of the gene was used to create a specific xylanase mutant by transformation-mediated gene disruption via homologous recombination. Total extracellular xylanase activity in the mutant was reduced by 85-94%. When analyzed by cation exchange HPLC, culture filtrates of the mutant and wild type had identical protein profiles, but the mutant lacked the major peak of UV absorption corresponding to the major xylanase activity. Xylanase II activity was also missing in the mutant, but xylanase III activity was still present. The XYL1 mutant grew as well as the wild type on sucrose, on corn cell walls, and on xylan. The pathogenicity of the mutant was indistinguishable from the wild type, indicating that XYL1 is not required for pathogenicity.
Parkinson’s Disease Treatment as Seen from a Mechanical Point of View (2016)

Tremor is considered as the most common faced abnormal involuntary movement disorder and the source of functional disability. Parkinson disease (PD) is a slowly progressive degenerative disorder of the central nervous system caused by the lack in the level of dopamine. Levodopa is the most effective dopaminergic medication used to manage Parkinson symptoms. However, it will be the source of the motor fluctuation after several years. An uncommon type of medication is suggested to suppress the resting tremor of PD patients. In this paper, a vibration absorber is used as a mechanical treatment and designed to reduce critical angular displacement amplitude at the resonance frequency. Human hand is modeled dynamically at the musculoskeletal level to reflect Parkinsonism. Motion is considered due to shoulder, elbow, Biceps brachii and wrist muscles activation. Absorber’s geometry, materials properties and parameters are well chosen to satisfy the tuning condition. The solution to the equation of motion for the hand is shown in the frequency and time domains to check the performance of the absorber in reducing the flexion angular motion at the wrist joint. Results show that the absorber was very effective over a good frequency bandwidth. It was able to reduce 93% of tremors amplitude at the wrist joint in the frequency domain. This type of absorber has low cost, can operate without power requirements, and has a simple design. Since its effectiveness was proved when tested numerically, it is recommended to proceed to the manufacturing process and the experimental study.
In vitro expansion of hematopoietic stem cells (1997)

We have investigated the effects of interleukin 3 (IL-3) and IL-1 on in vitro expansion of murine hematopoietic progenitors and stem cells using a highly purified progenitor population. Lineage negative, Ly-6A/E+, c-kit+ bone marrow cells from male mice were cultured in suspension in the presence of stem cell factor, IL-6, IL-11 and erythropoietin with or without IL-3 or IL-1. An exponential increase in total nucleated cell counts and about a 10-fold enhancement of nucleated cells by IL-3 were observed during the initial 10 days. Addition of IL-3 hastened the development but significantly suppressed the peak production of colony-forming cells. Addition of IL-1 also significantly suppressed the numbers of progenitors. We then tested the reconstituting ability of the cultured cells by transplanting cells together with "compromised" marrow cells into lethally irradiated mice. The cells expanded from enriched cells in the absence of IL-3 or IL-1 revealed engraftment at two, six and 10 months, while addition of IL-3 or IL-1 to the cultures significantly reduced the reconstituting ability. IL-3 and IL-1 may have negative modulatory effects on the self-renewal of stem cells.

Capsular stabilization device to preserve lens capsule integrity during phacoemulsification with a weak zonule (2006)

We describe a new capsular stabilization device for suspending a lens with weak zonular support. It is flexible, 10.0 mm in length, and fashioned from 5-0 nylon. The contact portion is bent at 1.25 mm with an end bifurcating to form a T-shape to minimize stress on the capsular equator. After a continuous curvilinear capsulorhexis is created, the capsular stabilization devices to hook the capsulotomy margin are inserted. The T-shaped end is passed around the anterior capsular flap to fit the curvature of the equator. Phacoemulsification and aspiration using this device was performed in 12 eyes of 9 patients, and the usefulness and complications were analyzed. The capsular stabilization devices suspended the capsule and facilitated safe phacoemulsification in all eyes. Posterior capsule rupture occurred in 2 eyes. None of the cases had notable postoperative complications. This device ensures a stable capsule-iris complex and reduces surgical risks.

Pericytes. Morphofunction, interactions and pathology in a quiescent and activated mesenchymal cell niche. (2009)

We review the morphofunctional characteristics of pericytes and report our observations. After a brief historical background, we consider the following aspects of pericytes: A) Origin in embryonic vasculogenesis (mesenchymal stem cells, neurocrest and other possible sources) and in embryonic and postnatal life angiogenesis (pre-existing pericytes, fibroblast/ myofibroblasts and circulating progenitor cells). B) Location in pericytic microvasculature and in the other blood vessels (including transitional cell forms and absence in lymphatic vessels), incidence (differences depending on species, topographical location, and type and stage of vessels) and distribution (specific polarities) in blood vessels. C) Morphology (cell body, and longitudinal and circumferential cytoplasmic processes), structure (nucleus, cytoplasmic organelles and distribution of microtubules, intermediate filaments and microfilaments) and surface (caveolae system). D) Basement membrane disposition, formation, components and functions. E) Contacts with endothelial cells (ECs) (peg and socket arrangements, adherent junctions and gap junctions) and with basal membrane (adhesion plaques). F) Molecular expression (pericyte marker identification). G) Functions, such as vessel stabilization, regulation of vascular tone and maintenance of local and tissue homeostasis (contractile capacity and vessel permeability regulation), matrix protein synthesis, macrophage-like properties, immunological defense, intervention in coagulation, participation in mechanisms that regulate the quiescent and angiogenic stages of blood vessels (including the behaviour of pericytes during sprouting angiogenesis and intussuceptive vascular growth, as well as pericyte interactions with endothelium and other cells, and with extracellular matrix) and plasticity, as progenitor cells with great mesenchymal potential, originating other pericytes, fibroblast/myofibroblasts, preadipocytes, chondroblasts, osteoblasts, odontoblasts, vascular smooth muscle and myointimal cells. This mesenchymal capacity is seen in a broad section on the perivascular mesenchymal cell niche hypothesis and in the concept of pericyte and EC "marriage and divorce". H) Peculiar pericyte types, such as hepatic stellate cells (Ito cells), bone marrow reticular cells and mesangial cells. I) Involvement in pathological processes, such as repair through granulation tissue, pericyte-derived tumors, tumor angiogenesis and tumoral cell metastasis, diabetic microangiopathy, fibrosis, atherosclerosis and calcific vasculopathy, lymphedema distichiasis, chronic venous insufficiency, pulmonary hypertension, Alzheimer disease and multiple sclerosis. J) Clinical and therapeutic implications (de-stabilization of vessels or formation of a stable vasculature).
Mechanism of the First Lithiation/Delithiation Process in the Anode Material CoFeOPO<sub>4</sub>@C for Li-Ion Batteries (2018)

A cobalt iron oxyphosphate CoFeOPO4@C (abbreviated as CFP@C) anode was prepared via a solid-state route, and its electrochemical performance was investigated vs Li+/Li over a wide voltage range of 0.01–3.0 V at different current rates C/n (n = 20, 10, 5, 2, and 1). This anode material is able to intercalate more than six lithium ions into the structure at the C/10 current rate, delivering a specific capacity of 748.23 mAh g–1, which is much higher than the theoretical capacity (593.7 mAh g–1) calculated when the insertion of a five lithium ions is considered. A reversible capacity of 200 mAhg–1 was maintained after 30 cycles. Raman spectroscopy confirmed the incorporation of carbon layers into the CoFeOPO4@C composite. Scanning electronic microscopy revealed that CFP@C particles have an angular-flake shape with particle sizes ranging between 1 and 5 μm. In situ X-ray absorption spectroscopy of Fe and Co at the K-edge showed that both transition metals are active during the whole discharge and charge. In operando high-energy X-ray diffraction revealed that this material undergoes a gradual evolution of the structure with lower crystallinity after the first discharge. Correlating electrochemical performance to the structural and electronic features indicated that the cycling mechanism of the CFP@C anode material exhibits a combination of intercalation and conversion processes.
Ensemble of shape functions for 3D object classification (2011)

This work addresses the problem of real-time 3D shape based object class recognition, its scaling to many categories and the reliable perception of categories. A novel shape descriptor for partial point clouds based on shape functions is presented, capable of training on synthetic data and classifying objects from a depth sensor in a single partial view in a fast and robust manner. The classification task is stated as a 3D retrieval task finding the nearest neighbors from synthetically generated views of CAD-models to the sensed point cloud with a Kinect-style depth sensor. The presented shape descriptor shows that the combination of angle, point-distance and area shape functions gives a significant boost in recognition rate against the baseline descriptor and outperforms the state-of-the-art descriptors in our experimental evaluation on a publicly available dataset of real-world objects in table scene contexts with up to 200 categories.
The Properties of Vibration Absorption according to the Diameter of Fiberous $BaTiO_3$ Powder (1994)

Recently, sound and mechanical vibration are becoming important problems in our life. In the present study, the measurement of vibration absorption characteristics of barium titanate ceramics and the investigation of its relationship to microstructures were carried out. The barium titanate ceramics is expected to be better vibration absorption material owing to its chemical and physical stability than other conventional vibration absorbers like glasswool board. Barium titanate ceramics were prepared by sintering fiberous crystallites in order to enhance the vibration absorption characteristics. The fiberous ceramics were prepared through the ionic exchange after the preparation of fiberous with 0.2, 1.2, 2.0, diameter length by KDC method. The fiberous crystallites were oriented in a plane perpendicular to the press direction and sintered. The investigation of the grain diameters of the sintered ceramics, equivalent factor, electromechanical coupling factor(), and the generated voltage(V) shows that the grain's diameter decreases with the increase of the diameter of the used fiberous crystallites. The vibration absorption increases the crystallites' diameter. That means that the vibration absorption increases with the internal friction of grain boundary. Which was identified by the investigation of the equivallent circuit.
Total Phenol, Catechin, and Caffeine Contents of Teas Commonly Consumed in the United Kingdom (2002)

Levels of total phenol, catechins, and caffeine in teas commonly consumed in the United Kingdom have been determined using reversed phase high-performance liquid chromatography. Tea bags or tea leaves were purchased from local supermarkets and extracted in boiling water for 5 min. The resulting data showed considerable variability in both total phenols [80.5-134.9 mg/g of dry matter (DM) in black teas and 87-106.2 mg/g of DM in green teas] and catechins (5.6-47.5, 51.5-84.3, and 8.5-13.9 mg/g of DM in black, green, and fruit teas, respectively); this was most probably a result of differing agronomic conditions, leaf age, and storage during and after transport, as well as the degree of fermentation. Caffeine contents of black teas (22-28 mg/g of DM) were significantly higher than in less fermented green teas (11-20 mg/g of DM). The relative concentration of the five major tea catechins ranked EGCG > ECG > EC > EGC > C. The estimated U.K. dietary intakes of total tea catechins, calculated on the basis of an average tea consumption of three cups of tea (200 mL cup, 1% tea leaves w/v), were 61.5, 92.7, and 405.5 mg/day from fruit teas, black teas, and green teas, respectively. The coefficients of variation were 19.4, 88.6, and 17.3%, respectively, indicating the wide variation in these intakes. The calculated caffeine intake ranged between 92 and 146 mg/day. In addition, many individuals will consume much larger quantities of tea, of various strengths (as determined by the brewing conditions employed). This broad spread of U.K. daily intakes further emphasizes the need for additional research to relate intake and effect in various population groups.
Crosslinking photocopolymerization of acrylic acid (and N-vinylpyrrolidone) with triethyleneglycol dimethacrylate initiated by camphorquinone/ethyl-4-dimethylaminobenzoate (2000)

In this article, we report the camphorquinone/amine visible-light-induced photocopolymerization of monofunctional acrylic acid (AA), N-vinylpyrrolidone (NVP), or both with difunctional triethyleneglycol dimethacrylate (TEGDMA) monomers followed by the crosslinking of pendant double-bond groups of the resulting homopolymers and copolymers. Our primary objective was to study the photocopolymerizability of various mixtures of AA, NVP, and TEGDMA compositions at different molar ratios in air. The photocopolymerization of AA with TEGDMA occurred with the formation of two peaks at different rates of polymerization. © 2000 John Wiley & Sons, Inc. J Polym Sci A: Polym Chem 38: 876–886, 2000
Improved Light Extraction in AlGaInP-Based LEDs Using a Roughened Window Layer (2008)

Surface-textured light-emitting diodes (LEDs) have been fabricated using a combination of natural lithography and dry etching techniques. Here, the randomly positioned polystyrene spheres are used as a mask for dry etching. The p-GaP window layer was successfully etched to achieve nanopillars on its surface. It was found that the surface-textured LEDs with the p-GaP nanopillars revealing a diameter of , a density of , and a depth of have maximum luminance intensity. Output power of the surface-textured LED increased about 70% compared with the planar-surface LED at a forward current of . The LED window with nanopillar diameter (, half of wavelength) and depth (, ) resulting in much light extraction compared with flat-surface LEDs or deeper nanopillars has been demonstrated by experiment and simulation. After a aging test, luminance intensity and voltage fluctuation do not exceed . These results indicated that AlGaInP-based LEDs with a roughened surface did not exhibit deteriorated performance.
