Fast feature-based vector quantization algorithm of image coding (1995)

A fast vector quantization algorithm is presented that exploits the spatial redundancy between neighboring vectors of pixels in an image to improve the performance of the triangle inequality elimination ruler, and employs the integral projection technique, a dimension-reduction method, to reduce the computational complexity of calculating distortion measure. Application of dimension reduction in distortion measures may result in some degradation of objective image quality. But a significant complexity reduction of over 90% in comparison with the conventional full-search method can be achieved. The degradation of image quality is only less than 0.2 dB in peak signal-to-noise ratio (PSNR). Acceptable image quality should be obtained successfully.
The Subjective Psychoactive Effects of Oral Dronabinol Studied in a Randomized, Controlled Crossover Clinical Trial for Pain (2013)

In pain patients, oral dronabinol has similar psychoactive effects to smoking marijuana. This risk must be considered in any decision to prescribe cannabinoid medications for pain.
Unipolar resistive switching and mechanism in Gd-doped-TiO<sub>2</sub>-based resistive switching memory devices (2011)

Gd-doped-TiO2-based resistive switching random-access memory (RRAM) devices with MOM structure of top metal electrode (W, Ti)/Gd-doped-TiO2/Pt/Ti/SiO2/Si were fabricated, and resistive switching characteristics were investigated. The W/Gd-doped-TiO2/Pt RRAM device showed typical unipolar resistive switching behavior irrespective of the bias polarity on the W top electrode. However, no unipolar switching was observed in the Ti/Gd-doped-TiO2/Pt devices when positive bias was applied on the Ti top electrode. A new resistive switching model was proposed to explain the unipolar switching behavior in the W/Gd-doped-TiO2/Pt RRAM device, based on the formation and destruction of conducting filaments which result from pinning and unpinning effects of surface trap states of oxide film on the Fermi level of metal electrode. The model clearly elucidates the mechanism of the low resistance state (LRS) and the high resistance state (HRS) as well as the switching behavior between LRS and HRS in the W/Gd-doped-TiO2/Pt RRAM device. The model also indicates the important role of the metal electrode material in unipolar resistive switching of oxide-based RRAM devices.
Some Applications of the Fourier Transform in Algebraic Coding Theory (2015)

This expository article describes two uses of the Fourier transform of interest in algebraic coding theory: the MacWilliams identities on weight enumerators of linear codes and the decomposition of a semi-simple group algebra of a finite group into a direct sum of matrix rings.

Reduced filler flocculation in the silica-filled styrene–butadiene–glycidyl methacrylate terpolymer (2015)

This study presents a method to improve the dispersion of silica in rubber compounds using a styrene-butadiene-glycidyl methacrylate terpolymer (GMA-SBR) synthesized by cold emulsion polymerization. It has been demonstrated that silica particles in conventional rubbers tend to agglomerate during storage, as well as at the onset of vulcanization, because of their polarity. GMA-SBR can improve the compatibility with silica by the formation of covalent bonds between the epoxy groups of GMA-SBR and silanol groups on the silica surface. SBR 1721 and GMA-SBR silica-filled compounds were prepared without curatives by a kneader and a two-roll mill. After compounding, the reaction of the epoxy group, filler flocculation, and morphology of the compounds were analyzed using infrared spectroscopy, a rubber process analyzer, and transmission electron microscopy, respectively. In addition, the content of bound rubber in the compounds was determined by extracting the unbound rubber material with toluene. The GMA-SBR silica-filled compounds had a higher bound rubber content and exhibited significantly different filler flocculation and silica dispersion behaviors compared with the SBR 1721 silica-filled compounds.
Gel-Bead Delivery of Eimeria Oocysts Protects Chickens Against Coccidiosis (2012)

Vaccines composed of either virulent or attenuated Eimeria spp. oocysts have been developed as an alternative to medication of feed with ionophore drugs or synthetic chemicals. The purpose of this study was to evaluate the use of gel-beads containing a mixture of Eimeria acervulina, Eimeria maxima, and Eimeria tenella oocysts as a vaccine against coccidiosis. Newly hatched chicks (Gallus gallus domesticus) were either sprayed with an aqueous suspension of Eimeria oocysts or were allowed to ingest feed containing Eimeria oocysts-incorporated gel-beads. Control day-old chicks were given an equivalent number of Eimeria oocysts (10(4) total) by oral gavage. After 3 days, chicks were randomly assigned to individual cages, and feces were collected between days 5 and 8 postinfection. All samples were processed for total Eimeria oocysts. At 4 wk of age, all chickens and a control nonimmunized group received a high-dose E acervulina, E maxima, and E. tenella challenge infection. Oocyst excretion by chicks fed gel-beads or inoculated by oral gavage was 10- to 100-fold greater than that of chicks spray-vaccinated with the Eimeria oocysts mixture (log 6.3-6.6 vs. log 4.8). Subsequent protection against challenge as measured by weight gain and feed conversion efficiency was significantly greater (P < 0.05) in gel-bead and oral gavage groups compared with spray-vaccinated or nonimmunized groups. Also, gel-bead and oral gavage groups showed no significant difference (P > 0.05) in weight gain and feed conversion efficiency compared with nonchallenged controls. These findings indicate that incorporation of Eimeria spp. oocysts in gel-beads may represent an effective way to deliver live oocyst vaccines to day-old chicks for preventing subsequent outbreaks of coccidiosis in the field.
Acceptorless, Reversible Dehydrogenation and Hydrogenation of <i>N</i>-Heterocycles with a Cobalt Pincer Catalyst (2015)

Acceptorless, reversible dehydrogenation and hydrogenation reactions involving N-heterocycles are reported with a well-defined cobalt complex supported by an aminobis(phosphine) [PN(H)P] pincer ligand. Several N-heterocycle substrates have been evaluated under dehydrogenation and hydrogenation conditions. The cobalt-catalyzed amine dehydrogenation step, a key step in the dehydrogenation process, has been independently verified. Control studies with related cycloalkanes suggest that a direct acceptorless alkane dehydrogenation pathway is unlikely. The metal–ligand cooperativity is probed with the related [PN(Me)P] derivative of the cobalt catalyst. These results suggest a bifunctional dehydrogenation pathway and a nonbifunctional hydrogenation mechanism.
Acute Tryptophan Depletion Alters Gastrointestinal and Anxiety Symptoms in Irritable Bowel Syndrome (2006)

IBS patients' GI and anxiety responses to changes in tryptophan load differ from controls. This suggests a difference in serotonergic functioning between these two groups and provides evidence to support the hypothesis that 5-HT dysfunction is involved in IBS.

Prevalence of xenotropic murine leukaemia virus-related virus in patients with chronic fatigue syndrome in the Netherlands: retrospective analysis of samples from an established cohort (2010)

This study failed to show the presence of XMRV in peripheral blood mononuclear cells of patients with chronic fatigue syndrome from a Dutch cohort. These data cast doubt on the claim that XMRV is associated with chronic fatigue syndrome in the majority of patients.
Configuration Relocation and Defragmentation for FPGAs (2001)

Custom computing systems exhibit significant speedups over traditional microprocessors by mapping compute-intensive sections of a program to reconfigurable logic [Hauck98]. However, the number and frequency of these hardware-mapped sections of code are limited by the requirement that the speedups provided must outweigh the considerable cost of configuration. Research has shown that the ability to relocate and defragment configurations on an FPGA dramatically decreases the overall configuration overhead [Li00]. This increases the viability of mapping portions of the program that were previously considered to be too costly. We therefore explore the adaptation of a simplified Xilinx 6200 series FPGA for relocation and defragmentation. Due to some of the complexities involved with this structure, we also present a novel architecture designed from the ground up to provide relocation and defragmentation support with a negligible area increase over a generic partially reconfigurable FPGA.
Touch Preparation Cytology of Breast Lumpectomy Margins With Histologic Correlation (1991)

Residual microscopic disease after lumpectomy for breast cancer may cause significant local recurrence. We evaluated one hundred fourteen consecutive breast lumpectomy margins in this study by touch preparation cytology. Cytologic preparations were intraoperatively correlated with gross and frozen section results and subsequently with permanent histologic sections of representative margins. Three specimens were cytologically unsatisfactory and 86 yielded benign findings, while material suggestive or diagnostic of malignancy was obtained from 25 specimens. Gross, frozen section, and permanent histologic margins were positive in 10, 17, and 22 cases, respectively. There were three false-positive touch preparation cytologic results, while frozen section specimens were false-negative in five cases. Sensitivity and specificity of touch preparation cytology were 100% and 96.6%, respectively, with a diagnostic accuracy of 97.3%. Touch preparation cytologic examination rapidly and reliably evaluates lumpectomy margins and overcomes sampling errors and artifacts related to frozen section evaluation. This technique currently complements frozen section evaluation of lumpectomy margins as part of a protocol aimed at reducing local recurrence of breast cancer.
Effective Eradication of Glioblastoma Stem Cells by Local Application of an AC133/CD133-Specific T-cell–Engaging Antibody and CD8 T Cells (2015)

Cancer stem cells (CSC) drive tumorigenesis and contribute to genotoxic therapy resistance, diffuse infiltrative invasion, and immunosuppression, which are key factors for the incurability of glioblastoma multiforme (GBM). The AC133 epitope of CD133 is an important CSC marker for GBM and other tumor entities. Here, we report the development and preclinical evaluation of a recombinant AC133×CD3 bispecific antibody (bsAb) that redirects human polyclonal T cells to AC133(+) GBM stem cells (GBM-SC), inducing their strong targeted lysis. This novel bsAb prevented the outgrowth of AC133-positive subcutaneous GBM xenografts. Moreover, upon intracerebral infusion along with the local application of human CD8(+) T cells, it exhibited potent activity in prophylactic and treatment models of orthotopic GBM-SC-derived invasive brain tumors. In contrast, normal hematopoietic stem cells, some of which are AC133-positive, were virtually unaffected at bsAb concentrations effective against GBM-SCs and retained their colony-forming abilities. In conclusion, our data demonstrate the high activity of this new bsAb against patient-derived AC133-positive GBM-SCs in models of local therapy of highly invasive GBM.
Purification and Properties of NADH:Nitrate Reductase from the Red Alga <italic>Porphyra yezoensis</italic> (1993)

Assimilatory nitrate reductase (NADH) (EC 1.6.6.1) from the red alga Porphyra yezoensis was purified 5,700-fold by a combination of polyethylene glycol (PEG) treatment, ammonium sulfate fractionation, chromatography on columns of butyl-Toyopearl 650-M, Blue Sepharose CL-6B, DEAE-cellulose (DE 52), and hydroxyapatite, gel filtration on Sephacryl S-400. The purest preparation of the enzyme had a specific activity of 12.5 units mg−1 protein. A single band of protein was detected after polyacrylamide gel electrophoresis under nondenaturing conditions. This band corresponded to a band that stained positive for reduced methyl viologen-nitrate reductase activity. The molecular weight of the native enzyme was estimated to be 220,000. A single band of a protein with a molecular weight of 100,000 was detected after sodium dodecyl sulfate-polyacrylamide gel electrophoresis. These results indicate that the native nitrate reductase is composed of two identical subunits. The homogeneous preparation of nitrate reductase had a UV/visible spectrum typical of a b-type cytochrome. The Km values for NADH and KNO3 were 23 μM and 64 μM, respectively. The pH optimum for the reaction catalyzed by the nitrate reductase was 8.3, while pH values that supported maximum partial activities ranged from 7.0 to 8.5. Sulfhydryl reagents, such as p-HMB and NEM, inhibited full and NADH-utilizing partial activities, while cyanide and azide were effective inhibitors of full and nitrate-reducing partial activities.
Therapy of pruritus (2010)

Sensory discrimination capabilities in patients with focal hand dystonia (2000)

To explore the concept that dystonia may result from dysfunction of the sensory system, 14 patients with focal hand dystonia were tested during two somatosensory discrimination tasks. Compared with controls, patients had a higher threshold in a task involving discrimination of two electric stimuli closely related temporally, an abnormality that correlated with the degree of severity of dystonia. There was no significant difference in a single-touch, gross localization task. The possible relevance of these findings to the pathogenesis of dystonia is discussed.

In Vitro Development of Human Killer–Immunoglobulin Receptor-Positive NK Cells (2009)

The in vitro culture system outlined in this chapter allows for the delineation of events that occur during the development of CD34(+) hematopoietic precursor cells into mature KIR(+) human NK cells. This system can also be utilized to study the effects of gene overexpression or knockdown on the process of NK cell differentiation through retroviral transduction and long-term culture. The necessary soluble factors and contact-dependent conditions for in vitro human NK cell development have been worked out in our laboratory over the past 16 years.
Purification and some properties of lignostilbene-.ALPHA.,.BETA.-dioxygenase responsible for the C.ALPHA.-C.BETA. cleavage of a diarylpropane type lignin model compound from Pseudomonas sp. TMY1009. (1989)

A novel dioxygenase, lignostilbene-α, β-dioxygenase (LSD), which catalyzes cleavage of the interphenyl double bond of lignin-derived stilbenes, was isolated. Four isozymes of LSD were separated from cell-free extracts of Pseudomonas sp. TMY1009 by ion-exchange chromatography on a DEAE-Toyopearl column. The major isozyme, LSD-I, was purified to electrophoretic homogeneity and characterized. LSD-I cleaved the interphenyl double bond of 1, 2-bis(4'-hydroxy-3'-methoxyphenyl)ethylene with the optimum pH at 8.5. The Km of LSD-I was 11 μM for the stilbene and 110 μM for oxygen. The molecular weight of LSD-I, which is composed of two identical subunits, was estimated to be 94, 000. LSD-I contained 1 g atom of iron per 1 mol of enzyme protein.
2-D curve matching using high curvature points: application to stereo vision (2002)

The authors present an efficient approach for reliably matching a set of points extracted from the environment of a mobile robot by means of passive stereo vision using two or three cameras. First, feature points corresponding to points with high curvature are extracted from each image using an efficient approach. The epipolar geometry and some powerful configuration constraints are then combined to match these points. A correspondence between curves is then established using the figural continuity. Results obtained on real images are given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Regulation of Antigen-Specific Immunoglobulin G Subclasses in Response to Conserved and Polymorphic<i>Plasmodium falciparum</i>Antigens in an In Vitro Model (2002)

Cytophilic antibodies (Abs) play a critical role in protection against Plasmodium falciparum blood stages, yet little is known about the parameters regulating production of these Abs. We used an in vitro culture system to study the subclass distribution of antigen (Ag)-specific immunoglobulin G (IgG) produced by peripheral blood mononuclear cells (PBMCs) from individuals exposed to P. falciparum or unexposed individuals. PBMCs, cultivated with or without cytokines and exogenous CD40/CD40L signals, were stimulated with a crude parasite extract, recombinant vaccine candidates derived from conserved Ags (19-kDa C terminus of merozoite surface protein 1 [MSP1(19)], R23, and PfEB200), or recombinant Ags derived from the polymorphic Ags MSP1 block 2 and MSP2. No P. falciparum-specific Ab production was detected in PBMCs from unexposed individuals. PBMCs from donors exposed frequently to P. falciparum infections produced multiple IgG subclasses when they were stimulated with the parasite extract but usually only one IgG subclass when they were stimulated with a recombinant Ag. Optimal Ab production required addition of interleukin-2 (IL-2) and IL-10 for all antigenic preparations. The IgG subclass distribution was both donor and Ag dependent and was only minimally influenced by the exogenous cytokine environment. In vitro IgG production and subclass distribution correlated with plasma Abs to some Ags (MSP1(19), R23, and MSP2) but not others (PfEB200 and the three MSP1 block 2-derived Ags). Data presented here suggest that intrinsic properties of the protein Ag itself play a major role in determining the subclass of the Ab response, which has important implications for rational design of vaccine delivery.
Segmentation of Camera Captured Business Card Images for Mobile Devices (2011)

Due to huge deformation in the camera captured images, variety in nature of the business cards and the computational constraints of the mobile devices, design of an efficient Business Card Reader (BCR) is challenging to the researchers. Extraction of text regions and segmenting them into characters is one of such challenges. In this paper, we have presented an efficient character segmentation technique for business card images captured by a cell-phone camera, designed in our present work towards developing an efficient BCR. At first, text regions are extracted from the card images and then the skewed ones are corrected using a computationally efficient skew correction technique. At last, these skew corrected text regions are segmented into lines and characters based on horizontal and vertical histogram. Experiments show that the present technique is efficient and applicable for mobile devices, and the mean segmentation accuracy of 97.48% is achieved with 3 mega-pixel (500-600 dpi) images. It takes only 1.1 seconds for segmentation including all the preprocessing steps on a moderately powerful notebook (DualCore T2370, 1.73 GHz, 1GB RAM, 1MB L2 Cache).
The role of leukotriene D4 in allergic rhinitis. (1988)

We investigated the clinical significance of leukotriene D4 (LTD4) in nasal symptoms of allergy and compared this with antigen and histamine. Nasal provocations were carried out in patients with allergic rhinitis using serially increasing doses of LTD4, histamine, or antigen. The nasal responses induced were evaluated by counting the number of sneezes, the quantity of nasal secretion, and of nasal airway resistance. When the effects of topical provoking agents were compared at the threshold concentration, LTD4 produced no sneezing--unlike antigen and histamine--increased nasal secretion to a lesser degree than antigen and histamine (P less than .001), and increased nasal airway resistance similar to histamine but less than antigen (P less than .1) and longer than histamine, and similar to antigen in duration. LTD4 was approximately 5,000 times stronger than histamine in threshold concentration for nasal response. In conclusion, LTD4 plays an important role in nasal allergy presumably through long lasting and strong nasal blockage effects.
A novel missense mutation in the human plasmin inhibitor (alpha<sub>2</sub>‐antiplasmin) gene associated with a bleeding tendency (1999)

Heterozygosity for a G --> A mutation converting Val384(GTG) to Met(ATG) associated with plasmin inhibitor (alpha2-antiplasmin) deficiency was identified in three family members with bleeding tendency. The proband had traumatic breast haematoma and per-/postoperative bleeds. An affected daughter required a blood transfusion after a normal delivery and a son had prolonged bleeding after tooth extraction. The plasma plasmin inhibitor activities of the affected family members were reduced to 49-66% of normal. The antigenic concentrations determined by electroimmunoassay were reduced to 57-68% of normal. Crossed immunoelectrophoresis of plasma from the proband showed a normal pattern. The amino acid Val384 is located eight residues C-terminal (P8') of the P1 residue (Arg376) in the reactive site. The P8' residues of bovine and mouse plasmin inhibitor are both Val. Among other serpins the P8' residue is unconserved. The mutation was not present in the non-affected family member or 30 blood donors. In addition to the Val384Met mutation two new polymorphisms Ala-26(GCG)/Val(GTG) and Arg407(AGG)/Lys(AAG) and one previously reported polymorphism Arg6(CGG)/Trp(TGG) were identified in the plasmin inhibitor gene of the family. The allelic frequencies among 30 blood donors with normal values of plasma plasmin inhibitor (functional) were 0.84/0.16 for C/T in codon -26, 0.81/0.19 for C/T in codon 6 and 0.83/0.17 for G/A in codon 407.
