On/Off Photoswitching of the Electropolymerizability of Terthiophenes (2008)

In this contribution the polymerization of terthiophene, to form an alkene bridged alpha,alpha-coupled sexithiophene polymer, is controlled by light; i.e. the electropolymerizability of the monomer 1F is switched off and on with UV and visible light, respectively. The system comprises of both bis-terthiophene and photochromic dithienylethene units. The presence of a light-switchable unit allows on-off switching of the electropolymerization of the monomer with light. Furthermore the incorporation of the dithienylethene in the polymer backbone increases dramatically the homogenity of the polymer formed (i.e., only sexithiophene units are formed). The derived films are robust and fully retain electrochromic behavior as has been demonstrated through cyclic voltammetry while spatial control (patterning) is readily achieved by applying simple optical masking techniques.

Temperate Phages of Streptomyces venezuelae: Lysogeny and Host Specificity Shown by Phages SV1 and SV2 (1982)

The generalized transducing phage SV1 of Streptomyces venezuelae lysogenizes its host with low efficiency and is therefore temperate. Phage SV2 is also temperate in S. venezuelae, which it lysogenizes more efficiently than SV1. Prophage SV2 is the first example of a u.v.-inducible prophage in Streptomyces. Stable double lysogens able to produce both SV1 and SV2 and insensitive to each phage have been isolated. The relative efficiencies of plating of SV1 and SV2 on four different strains of S. venezuelae indicate that, between them, these strains have four different host specificities. The molecular basis of each host specificity remains to be determined.
Voltage-current characteristics of an AC arc for different electrode separations with application to electrosurgery II (2002)

For pt. I, see ibid., p.35-6 (1993). A study of the effect of linear electrode displacement in various irrigant solutions commonly used during transurethral electrosurgery is discussed. Frequency and electrode type were held constant. A bipolar configuration was used. Results indicated that solutions such as glycine tap water, distilled water and sterile water displayed a capacitive response to the AC applied signal. Electrodes immersed in glycine, distilled water, and sterile water showed no arcing. A complete understanding of the effects of electrode separation and other parameters such as irrigant solutions may help engineers to design hazard free electrosurgical apparatus.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Cognitive Impairment That Is Induced by (R)-Ketamine Is Abolished in NMDA GluN2D Receptor Subunit Knockout Mice (2019)

Although the N-methyl-D-aspartate receptor antagonist ketamine has attracted attention because of its rapid and sustained antidepressant effects in depressed patients, its side effects have raised some concerns. Ketamine is a racemic mixture of equal amounts of the enantiomers (R)-ketamine and (S)-ketamine. The neural mechanisms that underlie the differential effects of these enantiomers remain unclear. We investigated cognitive impairment that was induced by ketamine and its enantiomers in N-methyl-D-aspartate GluN2D receptor subunit knockout (GluN2D-KO) mice. In the novel object recognition test, (RS)-ketamine and (S)-ketamine caused cognitive impairment in both wild-type and GluN2D-KO mice, whereas (R)-ketamine induced such cognitive impairment only in wild-type mice. The present results suggest that the GluN2D subunit plays an important role in cognitive impairment that is induced by (R)-ketamine, whereas this subunit does not appear to be involved in cognitive impairment that is induced by (RS)-ketamine or (S)-ketamine.
Permeation of propane and propylene thrugh cellulosic polymer membranes (1989)

Abstract Cellulosic polymers were tested by measuring their permeabilities of propane and propylene. High permeabilities and selectivities were obtained with ethyl cellulose membranes. Hollow fibers coated with ethyl cellulose were made through a solution coating method. Microporous polypropylene hollow fibers were used as base material. A dense layer of ethyl cellulose about 6–10 μm in thickness was formed on the microporous hollow fiber. The performance of a coated membrane column was tested for the separation of propane and propylene mixture gas. It was concluded that ethyl cellulose membranes have a good potential for the separation of olefins form saturated hydrocarbons.

Nanoparticles: Functionalization and Multifunctional Applications in Biomedical Sciences (2010)

Rapid innovations in nanomedicine have increased the likelihood that engineered nanomaterials will eventually come in contact with humans and the environment. The advent of nanotechnology has created strong interest in many fields such as biomedical sciences and engineering field. Central to any significant advances in nanomaterial based applications will be the development of functionalized nanoparticles, which are believed to hold promise for use in fields such as pharmaceutical and biomedical sciences. Early clinical results have suggested that functionalization of nanoparticles with specific recognition chemical moieties indeed yields multifunctional nanoparticles with enhanced efficacy, while simultaneously reducing side effects, due to properties such as targeted localization in tumors and active cellular uptake. A prerequisite for advancing this area of research is the development of chemical methods to conjugate chemical moieties onto nanoparticles in a reliable manner. In recent years a variety of chemical methods have been developed to synthesize functionalized nanoparticles specifically for drug delivery, cancer therapy, diagnostics, tissue engineering and molecular biology, and the structure-function relationship of these functionalized nanoparticles has been extensively examined. With the growing understanding of methods to functionalize nanoparticles and the continued efforts of creative scientists to advance this technology, it is likely that functionalized nanoparticles will become an important tool in the above mentioned areas. Therefore, the aim of this review is to provide basic information on nanoparticles, describe previously developed methods to functionalize nanoparticles and discuss their potential applications in biomedical sciences. The information provided in this review is important in regards to the safe and widespread use of functionalized nanoparticles particularly in the biomedicine field.
논문 : 조선후기 화승 연구(2): 해운당 익찬 (2002)

Haewundang (海雲堂) Ikchan(益贊) was a monk painter who worked in Jeonra-do area in the 19th centuy. He was one of the remarkable monk painters around Jeonra-do including CHeonyeo(天如) and Naewon(乃圓). Currently his life story is not known in detail. It seems that he was born around 1800, started paining around 1820, painted for 40 years till around 1860, and passed away between 1860 and 1870. Presently approximately 30 paintings are transcended. He was an assistant of Cheonyeo or Naewon till approximately 1845, and he became `Chief Assistant Painter` around 1850. In 1854 he became a `Chief Painter`, and he painted many paintings during the period. His works may be divided into four phases, considering the time he lived and the role he played. The first phase is 1820~1830. Only two paintings of this period exist today. Although he was an assistant, the characteristic Buddhist painting was already composed to some extent. In the second phase(1830~1840) he painted with the remarkable monk painters, Cheonyeo and Naewon. He could learn the characteristics of Buddhist paintings in Jeonra-do. In the third phase(1840~1850), he worked with Cheonyeo and Naewon, or worked independently with his own assistants. He succeeded to Euigyeom(義兼), an 18th century monk painter, In the fourth phase(1850~1862), he painted actively and produced many Buddhist paintings in large temples in Jeonranam-do and Jeonrabuk-do as a Chief painter. In particular, he produced `Three Buddha Painting(三佛會圖)` in Hwaeomsa, drawn to pray for the wllness of the royal family. It is a masterpiece that he painted with 30 assistant monks. His mature brush movement and skills are shown in the painting. Although he might paint more after this, no works after 1862 are left now. Looking into the characteristics of his Buddhist painting, he produced paintings with different compositions from traditional Buddhist paintings. The same characteristic is also found in the works of Cheonyeo, one of the best painting monks in Jeonra-do area. It found in the works of Cheonyeo, one of the best painting monks in Jeonra-do area. It played an important role in 19th century Buddhist paintings to have various compositions. People on his paintings have big and round faces, bold foreheads and small eyes, noses and ears. He followed traditional Buddhist coloring techniques such as using red and green as base colors. But he used white color frequently. Additionally, he used light green and black ink as well. Although the tradition he established was succeeded by his fellows including Deokrin(德麟), Dosun(道詢) and Juneon(後彦), generally the tradition was not succeeded to the descendants and Jeonra-do Buddhist paintings that succeeded to the traditional style could not be transcended any more.
Solid-Phase Synthesis of Oligosaccharide Drugs: A Review (2009)

Solid- phase synthesis is an approach, where synthetic transformation in carbohydrates are carried out with one of the reactant molecule attached to an insoluble material referred as polymeric support via linker. In recent years, it has been extensively accepted as fast and accurate method for the synthesis of biologically active oligosaccharides. This review attempts to focus on various methods of oligosaccharide synthesis by solid- phase including their applications.
Innate Immunity to Intraphagosomal Pathogens Is Mediated by Interferon Regulatory Factor 8 (IRF-8) That Stimulates the Expression of Macrophage-specific Nramp1 through Antagonizing Repression by c-Myc (2007)

Macrophages are a central arm of innate immune defense against intracellular pathogens. They internalize microbes into phagosomes where the invaders are being killed by oxygen and nitrogen reactive species. Despite this battery of antimicrobial molecules, some are able to thrive within the phagosome thus termed intraphagosomal pathogens among which are Salmonella, Leishmania, and Mycobacteria. In mice, a single dominant gene termed Nramp1/Slc11a1 controls innate resistance to such pathogens. This gene is expressed exclusively in myeloid cells. Previously, we have shown that the restricted expression of Nramp1 is regulated by a myeloid cell-specific transcription factor termed IRF-8/ICSBP. It is demonstrated here that the induction of Nramp1 expression in activated macrophages is accompanied by a promoter shift from a repression state elicited by c-Myc to an activation state elicited by the induction of IRF-8 in activated macrophages. This transition from repression to activation is facilitated by a competitive protein-protein interaction with the transcription factor Miz-1. To show that IRF-8 is directly involved in the elimination of intraphagosomal pathogens through the regulation of Nramp1 gene expression, we bred wild type as well as IRF-8 and Nramp1 null mouse strains and examined macrophages derived from bone marrow and peritoneum. Our results clearly show that the absence of IRF-8 and Nramp1 leads to the same phenotype; defective killing of intraphagosomal Salmonella enterica serovar typhimurium and Mycobacterium bovis. Thus, interplay between repression and activation state of the Nramp1 promoter mediated by IRF-8 provides the molecular basis by which macrophages resist intraphagosomal pathogens at early stage after infection.
T1 measurement using a short acquisition period for quantitative cardiac applications (2005)

Myocardial signal intensity curves for myocardial perfusion studies may be made quantitative by the use of T1 measurements made after the first-pass of contrast agent. A short data acquisition method for T1 mapping is presented in which all data for each T1 map are acquired in a short breath hold, and the slice geometry and timing in the cardiac cycle exactly match that of the dynamic first-pass perfusion sequence. This allows accurate image registration of the T1 map with the first-pass series of images. The T1 method is based on varying the preparation-pulse delay time of a saturation recovery sequence, and in this implementation employs an ECG-triggered, single-shot, spoiled gradient echo technique with SENSE reconstruction. The method allows T1 estimates of three slices to be made in fifteen heartbeats. For a range of samples with T1 values equivalent to those found in the myocardium during the first-pass of contrast agent, T1 estimates were accurate to within 6%, and the variation between slices was 2% or less.
5GCAR project D3.1 Intermediate 5G V2X Radio (2018)

The 5GCAR project aims to contribute to 5G network design, and specifically to design V2X technology components for V2X use case classes identified in the project. The requirements on reliability, latency, data rates, spectral and energy efficiency cannot be fully supported by today’s wireless networks and V2X solutions and call for novel and innovative approaches, including the design of a new radio interface.
Generalized Nonnegative Matrix Approximations with Bregman Divergences (2005)

Nonnegative matrix approximation (NNMA) is a recent technique for dimensionality reduction and data analysis that yields a parts based, sparse nonnegative representation for nonnegative input data. NNMA has found a wide variety of applications, including text analysis, document clustering, face/image recognition, language modeling, speech processing and many others. Despite these numerous applications, the algorithmic development for computing the NNMA factors has been relatively deficient. This paper makes algorithmic progress by modeling and solving (using multiplicative updates) new generalized NNMA problems that minimize Bregman divergences between the input matrix and its low-rank approximation. The multiplicative update formulae in the pioneering work by Lee and Seung [11] arise as a special case of our algorithms. In addition, the paper shows how to use penalty functions for incorporating constraints other than nonnegativity into the problem. Further, some interesting extensions to the use of link functions for modeling nonlinear relationships are also discussed.

Change in Physicochemical and Storage Characteristics of Jeungpyun by Addition of Pectin and Alginate powder (2005)

This study investigated the effect of addition of pectin and alginate on the Physicochemical and retrogradation Properties of Jeungpyun, a Korean traditional fermented rice cake. The volume of batters with alginate and Pectin was significantly larger than that of control. Jeungpyun samples with Pectin and alginate had a larger volume with uniform and smaller cell size. All samples showed largest foaming capability after second fermentation. Foaming capability of the control ( addition of pectin and alginate) was significantly larger than that of the treated samples. The amount of reducing sugar tended to increase during fermentation but decreased after steaming, which was due to the increase in hydrolysis of starch. On the contrary, the content of free sugar was slightly decreased during fermentation but slightly increased after steaming. The control contained the largest amount of free sugar after steaming. The microstructure of starch particles after fermentation showed completely dispersed starch granules with air bubbles. After steaming, the structure was sponge-like in all samples. Samples with added alginate and pectin had significantly higher water binding capacity than those of the control. All samples showed noticeably increased solubility and swelling power at with the control being significantly lower than the treated samples. Retrogradation was measured with -amylase and the retrogradation process of the sample with added alginate and pectin proceeded slower than that of the control. The relative crystallinity was observed through X-ray diffraction method and samples with added alginate and pectin had smaller crystallinity and delayed retrogradation compared to the control. Thus, Jeungpyun with the addition of alginate and Pectin demonstrated improved functionality and dietary fiber addition effect. The storage period of was extended as the retrogradation rate was delayed by the addition of dietary fibers.
Evidence for increased bone resorption in patients with progressive knee osteoarthritis: Longitudinal results from the Chingford study (2002)

Our data demonstrate that bone resorption is increased in patients with progressive knee OA and is not increased in those with nonprogressive knee OA. The increase in bone resorption seen in patients with progressive knee OA is similar to that observed in patients with osteoporosis. Altered bone turnover may be a diagnostic or therapeutic target in patients with progressive OA.
Treatment of diverticulitis of the large intestine and its complications (1959)

Summary and Conclusions There is no intra-abdominal surgical condition requiring more judgment concerning the indications for definitive surgery or the management of acute complications than diverticulitis. It is my feeling from observing the service cases in hospitals with which I am associated that more errors are made by doing too much than too little during the surgical procedure. This applies to the acute emergencies and also to the elective operations. Patients with free perforation or abscess formation from acute diverticulitis rarely, if ever, need a proximal colostomy. In the 27 cases in this series, there was a mortality rate of 7.5 per cent after simple closure of the performation and drainage. In patients with fistula formation or complete obstruction, it is essential that a proximal colostomy be performed before definitive surgery. In most patients needing definitive surgery for diverticulitis and in many instances in partial obstruction from acute diverticulitis, a one-stage operation can be performed without a proximal colostomy. Massive hemorrhage was a most unusual complication in this group of patients and presented no surgical problem.
