Class III peroxidases in plant defence reactions (2008)

When plants are attacked by pathogens, they defend themselves with an arsenal of defence mechanisms, both passive and active. The active defence responses, which require de novo protein synthesis, are regulated through a complex and interconnected network of signalling pathways that mainly involve three molecules, salicylic acid (SA), jasmonic acid (JA), and ethylene (ET), and which results in the synthesis of pathogenesis-related (PR) proteins. Microbe or elicitor-induced signal transduction pathways lead to (i) the reinforcement of cell walls and lignification, (ii) the production of antimicrobial metabolites (phytoalexins), and (iii) the production of reactive oxygen species (ROS) and reactive nitrogen species (RNS). Among the proteins induced during the host plant defence, class III plant peroxidases (EC 1.11.1.7; hydrogen donor: H(2)O(2) oxidoreductase, Prxs) are well known. They belong to a large multigene family, and participate in a broad range of physiological processes, such as lignin and suberin formation, cross-linking of cell wall components, and synthesis of phytoalexins, or participate in the metabolism of ROS and RNS, both switching on the hypersensitive response (HR), a form of programmed host cell death at the infection site associated with limited pathogen development. The present review focuses on these plant defence reactions in which Prxs are directly or indirectly involved, and ends with the signalling pathways, which regulate Prx gene expression during plant defence. How they are integrated within the complex network of defence responses of any host plant cell will be the cornerstone of future research.
Mycobacterial Contamination of Metalworking Fluids: Involvement of a Possible New Taxon of Rapidly Growing Mycobacteria (2000)

Contamination of air and metalworking fluid (MWF) systems with a rapidly growing mycobacterium (RGM) was detected in 1995 in a single manufacturing plant with recent cases of hypersensitivity pneumonitis (HP). Extensive environmental sampling was performed to determine the extent of the contamination and its variability over time. RGM were present in multiple indoor air samples, 100% of the central MWF storage tanks, and 75% of the freestanding cutting, drilling, and grinding machines. With one exception, contamination was limited to a recently introduced formulation (brand) of semisynthetic MWF used in 95% of the facility's machining operations. In general, the mycobacterial counts were stable over time, with the degree of contamination ranging from 10(2)-10(7) colony forming units (CFU)/mL. A few systems were culture positive for the mycobacterium (> 10(1) CFU/mL), changed to culture negative (< 10(1) CFU/mL), then changed back to culture positive without explanation. Samples obtained from diluted (5%) but unused MWF, a replenishment line with 2% unused MWF, an MWF pasteurizer, city water, and deionized water were culture negative for this species of mycobacterium. Inoculation and growth studies demonstrated that this mycobacterium does not grow in liquid samples of 5% unused MWF. By molecular techniques, the mycobacterial isolates consisted of a single strain and represented a previously undescribed taxon closely related to Mycobacterium chelonae/abscessus. The relationship of this mycobacterium to the cases of HP is unknown.
Paraoxonase cluster polymorphisms are associated with sporadic ALS (2006)

This study demonstrates evidence of significant association of variants in the Paraoxonase gene cluster with sporadic ALS and is compatible with the hypothesis that environmental toxicity in a susceptible host may precipitate ALS.
Distal myopathy with rimmed vacuoles: Novel mutations in the <i>GNE</i> gene (2002)

The authors present three novel missense mutations in the UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase (GNE) gene, the causative gene for hereditary inclusion body myopathy, in Japanese patients with distal myopathy with rimmed vacuoles. Seven out of nine patients had homozygous V572L mutation, one was a compound heterozygote with C303V and V572L mutations, and the remaining patient bore homozygous A631V mutation.
Quantum Key Distribution with High Loss: Toward Global Secure Communication (2003)

We propose a decoy-pulse method to overcome the photon-number-splitting attack for Bennett-Brassard 1984 quantum key distribution protocol in the presence of high loss: A legitimate user intentionally and randomly replaces signal pulses by multiphoton pulses (decoy pulses). Then they check the loss of the decoy pulses. If the loss of the decoy pulses is abnormally less than that of signal pulses, the whole protocol is aborted. Otherwise, to continue the protocol, they estimate the loss of signal multiphoton pulses based on that of decoy pulses. This estimation can be done with an assumption that the two losses have similar values. We justify that assumption.
Laryngeal Electrode Platform: An Indwelling Device for Mobilizing the Vocal Cords (1987)

By passing electrical current across the laryngeal mucosa and esophageal wall, the recurrent laryngeal nerve can be stimulated, thereby mobilizing the vocal cords. In designing a device that would utilize this phenomenon, we theorized that stability, targeting, and mucosal contact could be maximized by an indwelling device that would conform precisely to the topography of the posterior larynx. In five dogs, molds of the hypopharynx and proximal esophagus were fashioned in vivo by injection of an alginate compound. From each mold was constructed a vinyl platform blanketed with electrodes. Each platform fit snugly in place, and could activate the nerve consistently in any of the dogs. With as little as 3 mA pulsatile current, use of specific electrodes enabled bilateral abduction, more than doubling the resting glottic aperture. Bilateral adduction was sometimes attainable. Such a platform may have use in visualizing subglottic lesions, diagnosing laryngeal movement disorders, and facilitating intubation and extubation.

Low readout field magnetic resonance imaging of hyperpolarized xenon and water in a single system (2002)

Using a low-field magnetic resonance scanner, we have obtained images of gaseous polarized Xe129 and water cells at room temperature. This potentially low-cost imaging technique offers the possibility of high-resolution imaging using both polarized noble gas and proton magnetic resonance imaging of tissues in the same scanner.
Transgenic Mice Expressing Fibroblast Growth Factor 23 under the Control of the α1(I) Collagen Promoter Exhibit Growth Retardation, Osteomalacia, and Disturbed Phosphate Homeostasis (2004)

Mutations in the fibroblast growth factor 23 gene, FGF23, cause autosomal dominant hypophosphatemic rickets (ADHR). The gene product, FGF-23, is produced by tumors from patients with oncogenic osteomalacia (OOM), circulates at increased levels in most patients with X-linked hypophosphatemia (XLH) and is phosphaturic when injected into rats or mice, suggesting involvement in the regulation of phosphate (Pi) homeostasis. To better define the precise role of FGF-23 in maintaining Pi balance and bone mineralization, we generated transgenic mice that express wild-type human FGF-23, under the control of the alpha1(I) collagen promoter, in cells of the osteoblastic lineage. At 8 wk of age, transgenic mice were smaller (body weight = 17.5 +/- 0.57 vs. 24.3 +/- 0.37 g), exhibited decreased serum Pi concentrations (1.91 +/- 0.27 vs. 2.75 +/- 0.22 mmol/liter) and increased urinary Pi excretion when compared with wild-type littermates. The serum concentrations of human FGF-23 (undetectable in wild-type mice) was markedly elevated in transgenic mice (>7800 reference units/ml). Serum PTH levels were increased in transgenic mice (231 +/- 62 vs. 139 +/- 44 pg/ml), whereas differences in calcium and 1,25-dihydroxyvitamin D were not apparent. Expression of Npt2a, the major renal Na(+)/Pi cotransporter, as well as Npt1 and Npt2c mRNAs, was significantly decreased in the kidneys of transgenic mice. Histology of tibiae displayed a disorganized and widened growth plate and peripheral quantitative computerized tomography analysis revealed reduced bone mineral density in transgenic mice. The data indicate that FGF-23 induces phenotypic changes in mice resembling those of patients with ADHR, OOM, and XLH and that FGF-23 is an important determinant of Pi homeostasis and bone mineralization.
Deficiency of low density lipoprotein receptors in liver and adrenal gland of the WHHL rabbit, an animal model of familial hypercholesterolemia. (1981)

The WHHL (Watanabe heritable hyperlipidemic) rabbit has been proposed as an animal model for human familial hypercholesterolemia. Homozygous WHHL rabbits have marked increases in the plasma level of low density lipoprotein (LDL), removal of LDL from their plasma is delayed, and LDL receptors are absent from their cultured fibroblasts [Tanzawa, K., Shimada, Y., Kuroda, M., Tsujita, Y., Arai, M. & Watanabe, Y. (1980) FEBS Lett. 118, 81--84]. We here report that membranes from the liver and adrenal gland of WHHL rabbits lack high-affinity LDL receptors. In normal rabbit membranes, binding of LDL to this receptor required calcium and is inhibited by EDTA. The LDL receptor binds rabbit 125I-labeled beta-migrating very low density lipoprotein (beta-VLDL), which contains apoproteins B and E, as well as rabbit 125I-labeled LDL, which contains only apoprotein B. It does not bind high density lipoprotein or methyl-LDL. All of these properties are identical with those of the LDL receptor of cultured fibroblasts. We conclude that a deficiency of hepatic and adrenal LDL receptors contributes to the hypercholesterolemia of the WHHL rabbits.

Experimental infection of <i>Macaca nemestrina</i> with a Toronto Norwalk‐like virus of epidemic viral gastroenteritis (2002)

Norwalk virus (NV) and Norwalk-like viruses (NLVs) are common etiologic agents of viral gastroenteritis. Viral gastroenteritis is a common disease that is highly transmissible, spreading rapidly through families, institutions, and communities. Because methods for in vitro cultivation of Norwalk etiologic agents are not available, information regarding this syndrome has come largely from studies in human volunteers. Sequential passaging of an NLV through an immunoincompetent newborn pigtail macaque (Macaca nemestrina) may allow for the adaptation of a human NLV to a primate host, thus providing an animal model for investigating this disease. A fecal filtrate of human origin containing NLV, Toronto virus P2-A, was obtained from a patient during an epidemic of viral gastroenteritis. The filtrate was administered via nasogastric tube to three newborn pigtailed macaques. Clinical illness, which was characterized by diarrhea, dehydration, and vomiting, occurred in three monkeys. Reverse transcription-polymerase chain reaction (RT-PCR) and oligonucleotide probe analysis of RNA extracted from the stool samples following infection revealed viral RNA in all inoculated monkeys. Infection was also transmitted experimentally by feeding two additional newborn macaques a fecal filtrate prepared from the three previously infected animals. Detection of viral RNA in the stools of animals that received the fecal filtrate indicates that viral replication occurred in association with clinical illness. The susceptibility of Macaca nemestrina to infection with a Norwalk-like agent will facilitate the study of the mechanisms of the pathogenesis of NLV. This system may also have the potential to serve as a vaccine test model for human epidemic viral gastroenteritis.
Cloning and sequencing of the gene encoding thermophilic beta-amylase of Clostridium thermosulfurogenes (1988)

A gene coding for thermophilic beta-amylase of Clostridium thermosulfurogenes was cloned into Bacillus subtilis, and its nucleotide sequence was determined. The nucleotide sequence suggested that the thermophilic beta-amylase is translated from monocistronic mRNA as a secretory precursor with a signal peptide of 32 amino acid residues. The deduced amino acid sequence of the mature beta-amylase contained 519 residues with a molecular weight of 57,167. The amino acid sequence of the C. thermosulfurogenes beta-amylase showed 54, 32, and 32% homology with those of the Bacillus polymyxa, soybean, and barley beta-amylases, respectively. Twelve well-conserved regions were found among the amino acid sequences of the four beta-amylases. To elucidate the mechanism rendering the C. thermosulfurogenes beta-amylase thermophilic, its amino acid sequence was compared with that of the B. polymyxa beta-amylase. The C. thermosulfurogenes beta-amyulase contained more Cys residues and fewer hydrophilic amino acid residues than the B. polymyxa beta-amylase did. Several regions were found in the amino acid sequence of the C. thermosulfurogenes beta-amylase, where the hydrophobicity was remarkably high as compared with that of the corresponding regions of the B. polymyxa beta-amylase.

Lipid-Based Drug Delivery Systems for Cancer Treatment (2011)

It is a fact that chemotherapy agents have little specificity for cancer cells, this leading to low concentrations into the tumor interstititum and severe side effects on healthy tissues. The formulation of lipid-based nanomedicines against cancer has been hypothesized to improve drug localization into the tumor tissue and to increase the anticancer efficacy of concentional drugs, while minimizing their systemic adverse effects. In this review, special attention is devoted to the analysis of the state-of-the-art in the development of lipid-based drug carriers against cancer. Specifically, the most significant in vitro and in vivo results on the use of niosomes, liposomes, and solid lipid nanoparticles are revised. It is concluded that biodistribution profiles of chemotherapy agents can be controlled by their loading to such nanoplatforms. Lipid-based nanomedicines offer an interesting approach to the delivery of anticancer drugs to brain tumors, and to reverse multi-drug resistance of cancer cells. Finally, a deep evaluation of the applicability of drug delivery strategies in the formulation of lipid-based nanoplatforms is carried out. They involve active drug targeting (including ligand-mediated delivery, and stimuli-sensitive carriers), and passive drug targeting (through the enhanced permeability and retention effect) to tumors.
Ruminal degradability and intestinal digestibility of protein and amino acids in soybean and corn distillers grains products (2010)

New fractionation and fermentation technologies in the ethanol industry have resulted in the production of different forms of distillers grains (DG). Such products are reduced-fat, high-protein, and "modified" wet feeds. Characterization of protein fractions of these co-products and other commonly used feedstuffs is important for the formulation of dairy cattle diets. In situ and in vitro techniques were conducted to compare crude protein (CP) availability in 4 DG products with commonly used soybean proteins. Soybean protein products included solvent-extracted soybean meal (SBM; 44% CP), expeller soybean meal (ESBM), and extruded soybeans (ES). The DG products were conventional distillers dried grains with solubles, reduced-fat distillers dried grains with solubles (RFDGS), high-protein distillers dried grains, and modified wet distillers grains with solubles (MWDGS). Nylon bags containing 5 g of each feed were incubated in the rumen of 3 cannulated lactating cows for 2, 4, 8, 16, 24, and 48 h. The rapidly degradable CP fraction varied from 8.1 to 37.2% for SBM and MWDGS, respectively. The slowly degradable CP fraction was greatest for SBM, ES, and high-protein distillers dried grains (88.0%+/-3.7), followed by ESBM, distillers dried grains with solubles, and RFDGS (76.8+/-4.1%). The MWDGS had the lowest slowly degradable CP fraction (61.1%). The rate of degradation of the slowly degradable CP fraction ranged from 11.8 for SBM to 2.7%/h for RFDGS. Rumen-undegradable protein varied widely (32.3 to 60.4%), with RFDGS having the greatest and SBM the lowest concentrations. Intestinal digestibility of rumen-undegradable protein (IDP) was estimated by pepsin-pancreatin digestion of ruminally preincubated (16 h) samples. The IDP was greatest for SBM, ESBM, and ES (97.7%+/-0.75), whereas IDP of DG products was 92.4%+/-0.87. Similarly, total digestible protein was greatest (99.0%) for soybean products, whereas DG products had a total digestible protein of 96.0%. Intestinal digestibility of most AA in DG products exceeded 92% and was slightly lower than for soybean products, except for Lys, where the digestibility was 84.6% for DG compared with 97.3% for soybean products. Absorbable Lys was lower for DG (7.0 g/kg of CP) compared with ESBM and ES (average of 23.8 g/kg of CP). Dried DG, ESBM, and ES provided more absorbable AA compared with SBM and MWDGS. These results suggest that the AA availability from DG products is comparable with that from soybean products.
Computer Evaluation of the Multivariate Normal Integral (1972)

A method is described for the evaluation by computer of the multivariate normal integral, for arbitrary mean vector, covariance matrix, and region of integration. Evaluation is by means of a modification of a multidimensional adaptive Simpson's quadrature with error control, applied to the iterated integral. Examples are given for integrals of up to six dimensions.
HIV-2 Antiviral Potency and Selection of Drug Resistance Mutations by the Integrase Strand Transfer Inhibitor Elvitegravir and NRTIs Emtricitabine and Tenofovir In Vitro (2012)

The antiretrovirals EVG, FTC, and TFV showed potent inhibition of HIV-1 and HIV-2 in vitro and selected analogous mutations in HIV-2 and HIV-1. This suggests that the single tablet regimen of EVG/COBI/FTC/TDF should be studied as a treatment option for HIV-2 infection and would likely select for known resistance mutations.
Highly Enantioselective Epoxidation of Styrenes Catalyzed by Proline‐Derived <i>C</i><sub>1</sub>‐Symmetric Titanium(Salan) Complexes (2009)

Titanium tough! Novel proline-derived C1-symmetric titanium(salan) complexes have been used to catalyze the epoxidation of styrene derivatives with aqueous hydrogen peroxide as the oxidant (see scheme). High enantiomeric excesses ranging from 96 to 98 % were obtained.
AN APPROACH TO EXTRACT MOVING OBJECTS FROM MLS DATA USING A VOLUMETRIC BACKGROUND REPRESENTATION (2017)

Abstract. Data recorded by mobile LiDAR systems (MLS) can be used for the generation and refinement of city models or for the automatic detection of long-term changes in the public road space. Since for this task only static structures are of interest, all mobile objects need to be removed. This work presents a straightforward but powerful approach to remove the subclass of moving objects. A probabilistic volumetric representation is utilized to separate MLS measurements recorded by a Velodyne HDL-64E into mobile objects and static background. The method was subjected to a quantitative and a qualitative examination using multiple datasets recorded by a mobile mapping platform. The results show that depending on the chosen octree resolution 87-95% of the measurements are labeled correctly.
The Relationship Between Sural Nerve Morphometric Findings and Measures of Peripheral Nerve Function in Mild Diabetic Neuropathy (1991)

The morphological findings in sural nerve biopsy specimens from 15 diabetic patients with mild neuropathy were compared with control biopsies from eight non-neuropathic, non-diabetic subjects, and correlations were sought with electrophysiological studies and quantitative sensory tests for vibration, thermal, and current perception thresholds. Myelinated fibre density was reduced compared with control biopsies (4042 +/- 2090 (+/- SD) vs 6800 +/- 1100 mm-2; p less than 0.01). A strong correlation existed between myelinated fibre density and sural sensory conduction velocity (r = 0.84, p less than 0.001), sural action potential amplitude (r = 0.74, p less than 0.001), peroneal motor conduction velocity (r = 0.58, p less than 0.02), and median sensory amplitude (r = 0.64, p less than 0.01) but there was no correlation between myelinated fibre density and any quantitative sensory test. We conclude that conventional electrophysiological tests in the lower limb are reliable surrogate measures for structural abnormalities in early diabetic neuropathy.
Identification of a unique IgG Fc binding site in human intestinal epithelium. (1989)

In experiments to determine whether serum antibodies in patients with Crohn's disease could be used as probes for detecting potentially etiologic Ag in the patients' tissues, we found that peroxidase (HRP)-labeled IgG from healthy persons, as well as from the patients, bound to normal colonic and small intestinal epithelium, mostly or entirely to goblet cells. The binding was due to a reaction involving the Fc region of IgG because HRP-labeled Fc fragments of IgG bound, but HRP-Fab, HRP-IgA, and HRP-bovine albumin did not, and because binding of HRP-IgG was inhibited competitively by unlabeled IgG or Fc fragments but not by IgG Fab fragments or IgA. These immunohistochemical results were confirmed by ELISA with microtiter wells coated with a sonicated homogenate from human colonocytes. The epithelial IgG Fc binding site was characterized by SDS-PAGE as consisting of a high Mr (greater than 200,000 Da) and a 78,000-Da component. It bound all four subclasses of human IgG and bound aggregated as well as monomeric IgG. It is distinct from known human Fc-gamma R by lack of recognition by mAb to those receptors and differences in affinity for various subclasses of human and murine IgG. This unique IgG Fc binding site might be involved in immunologic defense of the gut, perhaps by mediating reactions between foreign Ag and the contents of goblet cells.
