Illuminating regeneration: noninvasive imaging of disease progression in muscular dystrophy (2013)

Muscular dystrophies are characterized by progressive muscle weakness and wasting. Among the key obstacles to the development of therapies is the absence of an assay to monitor disease progression in live animals. In this issue of the JCI, Maguire and colleagues use noninvasive bioluminescence imaging to monitor luciferase activity in mice expressing an inducible luciferase reporter gene in satellite cells. These cells proliferate in response to degeneration, therefore increasing the level of luciferase expression in dystrophic muscle.
Using Seasonal Climate Variability Forecasts to Plan Forest Plantation Establishment (1969)

Atmospheric scientists are now able to predict seasonal climate variations, with a relatively high level of skill. Knowledge of climatic conditions allows us to develop a seasonal management strategy for forest plantations and managed natural forests. Areas of application include seedling establishment, preparing for pests and diseases, fire management, harvest schedules and inventory management. This publication provides strategies to consider for pine plantation establishment in Florida and southern Alabama and Georgia. Seasonal climate conditions can be better predicted for this region because it is affected by the El Niño Southern Oscillation (ENSO) phenomenon. This document is ABE354, one of a series of the Agricultural and Biological Department, Florida Cooperative Extension Service, Institute of Food and Sciences, University of Florida.

<i>H. PYLORI</i>: SHOULD WE STILL BE LOOKING FOR IT? WHAT SHOULD WE BE DOING ABOUT IT? A CASE‐BASED APPROACH (2012)

Overview It is now recognized that many ulcers in the upper GI tract are the result of an infection, and that stress (as important as it may be for generating some GI symptoms) does not cause ulcers. Since the discovery of H. pylori by Marshall and Warren, we have also learned that the pathogen is linked with many other ailments, including marginal T cell lymphoma (aka MALT), gastric adenocarcinoma, functional dyspepsia, gastroesophageal reflux disease (GERD), lymphocytic gastritis, Menentrier's disease, dental caries, and iron deficiency anemia, among many others. It is noted that some of these links are proven and accepted (e.g. MALT), others are speculative or controversial (e.g. GERD, caries, iron deficiency). At the present time the prevalence of H. pylori has fallen in much of the Western world, however it remains a very important pathogen that continues to generate a large worldwide burden of illness. There is no question that there is an ongoing need to test and treat for H. pylori in our patients but in light of evolving data on diagnosis and treatment of H. pylori, this review will focus in a case-based style the following: when we should test, how we should test, and how we should treat this highly prevalent pathogen. This paper draws heavily from the American College of Gastroenterology management guidelines (see references), and focuses on salient clinical teaching points using up-to-date information on testing and treatment of H. pylori. Each vignette, below, presents a common clinical scenario, followed by a brief discussion of whether and how to test and treat H. pylori. Vignette #1: Uncomplicated GERD A 28-year-old woman is referred to you for ‘acid reflux’ symptoms for the past 3 years. She describes the pain as sharp, worse with eating, and occasionally associated with regurgitation of food, especially in the recumbent position. She received a histamine-2 receptor antagonist for these symptoms, but there was only partial improvement. She has not experienced unintended weight loss, rectal bleeding, vomiting, or dysphagia. Examination now does not reveal alarming features. Guaiac is negative and a complete blood count is normal. Which of the following should you do next? Start a 4-week trial of therapy with a proton pump inhibitor Refer for prompt esophagogastroduodenoscopy Test for H. pylori and treat if positive Lifestyle modifications and follow-up and for additional case vignettes http://www.worldendo.org/news-item-20111201.html
Yemanja-a layered event correlation engine for multi-domain server farms (2002)

Yemanja is a model-based event correlation engine for multi-layer fault diagnosis. It targets complex propagating fault scenarios, and can smoothly correlate low-level network events with high-level application performance alerts related to quality of service violations. Entity-models that represent devices or abstract components encapsulate entity behavior. Distantly associated entities are not explicitly aware of each other, and communicate through event propagation chains. Yemanja's state-based engine supports generic scenario definitions, prioritization of alternate solutions, integrated problem-state and device testing, and simultaneous analysis of overlapping problems. The system of correlation rules was developed based on device, layer, and dependency analysis, and reveals the layered structure of computer networks. The primary objectives of this research include the development of reusable, configuration independent, correlation scenarios; adaptability and the extensibility of the engine to match the constantly changing topology of a multi-domain server farm; and the development of a concise specification language that is relatively simple yet powerful.
Scene Matching between a Map and a Hand Drawn Sketch Using Spatial Relations (2007)

The goal of this work is to determine the object correspondence between a sketched map and the scene depicted by the sketch, e.g., as represented by an occupancy grid map (OGM) built by a robot. We describe a novel method based on spatial relations for accomplishing this task. Our method is based on using the histogram of forces as scene descriptors. We generate a correspondence map between two scene descriptors and evaluate its confidence. From this map, we generate a one-to-one object correspondence map for the two scenes such that the object correspondence confidence value is maximized. Challenges include the fact that the two scenes may differ in terms of the shape and size of the objects, their orientation, and the objects might be shifted due to translation. The approach is evaluated using several hand drawn sketches that were collected as a part of a user study. We believe that the ability to perform scene matching will make our sketch interface more robust and easier to use, thereby providing us with a more intuitive way of communicating with the robots
Characterization of New Bacterial Copolyesters Containing 3-Hydroxyoxoalkanoates and Acetoxy-3-hydroxyalkanoates (2000)

Two novel bacterial poly(3-hydroxyalkanoates) (PHAs) with either 3-hydroxy-7-oxooctanoate (HOO) and 3-hydroxy-5-oxohexanoate (HOH) or 8-acetoxy-3-hydroxyoctanoate (AHO), 6-acetoxy-3-hydroxyhexanoate (AHH), and 4-acetoxy-3-hydroxybutyrate (AHB) monomer units were produced at pilot scale. For the biosynthesis of these PHAs Pseudomonas oleovorans was cultivated at a 24 L scale in two-liquid-phase fed-batch processes using mineral salts medium and mixtures of 2-octanone/octane or n-octylacetate/octane as carbon sources. The bacterial accumulation of the polyesters was induced by nitrogen starvation and the addition of the substrate mixtures. Under these conditions, 26 and 45 g of PHA were isolated. The PHAs contained 10.3 and 3.3 mol % of oxo and acetoxy group monomers. Physical characterization was done with respect to their molecular weights, and thermal properties and similar results were found as for octane-based PHA. All monomer units have been identified by 2D 1H and 13C heteronuclear correlated NMR spectroscopy (HSQC, HMBC, and HSQC-TOCSY), and the composition of the copolyesters was quantified from 1H NMR spectra.

Effect of non-histone chromosomal proteins on transcription <i>in vitro</i> in sea-urchin (1978)

Non-histone chromosomal proteins prepared from chromosomal material of the sea-urchin Paracentrotus lividus affect RNA synthesis in vitro. 1. The extent of transcription can be radically changed from inhibition to stimulation, depending on the DNA/non-histone chromosomal proteins ratio. 2. A correlation exists between stage of development and influence on transcription. 3. Non-histone chromosomal proteins exert their action by intervening directly on some initiation step of RNA synthesis, as shown by the numbers of initiation events that take place in their presence or absence. 4. Stimulatory activity is observed only in restrictive conditions of ionic strength and temperature. These observations are in agreement with models that predict for non-histone chromosomal proteins a regulatory role on the transcription process exerted through a modulation of promoter availability.
[Atlanto-axial dislocation--instability index and indications for surgery (author's transl)]. (1976)

Thirty cases of atlanto-axial dislocation were investigated and the results are reported. The may be divided into 2 groups; (a) 15 cases of abnormalities of the odontoid process, i. e. 7 cases of os odontoideum, 7 cases of fractured odontoid, 1 cases of deformed odontoid, and (b) 15 cases with no abnormalities of the odontoid process. Neurological signs were noted in 14 cases which may be divided into the following three types, i.e. acute, recurrent, and chronic-progressive. The spinal canal diameter at the atlanto-axial level was measured in the position of flexion and extension using cervical tomography. The degree of motility thus obtained was expressed in terms of "Instability Index" (I. I.) devised in our clinic. In the group with neurological signs, the acute type showed an I. I. of 39 percent which was the highest value, and followed by 33 percent in the recurrent type. In the chronic-progressive type, the I. I. value was as low as 3.75 percent with a mean maximal diameter of 11.0 mm. Operation was performed in 16 cases. In 12 cases, posterior fusion was performed from the occipital bone to C3 or in some cases C4. In 3 cases, posterior decompression and fusion from the occipital bone to C3 were conducted. In one case, anterior decompression and fusion was performed by the transoral approach. The outcome was generally satisfactory. As a new method of posterior fusion, we have used "single bone-flap" method since 1972, that could fix the occipital bone and the cervical spines more tightly. In conclusion, the operation is indicated in the following cases; (1) when neurological signs are evident, (2) even in the abcence of neurological signs, (a) when the I. I. is high (over 20 percent), (b) even when the I. I. is low, when the maximal diameter of the canal is under 14.0 mm.
The Thrombomodulin/Protein C/Protein S Anticoagulant Pathway Modulates the Thrombogenic Properties of the Normal Resting and Stimulated Endothelium (1997)

We investigated the role of the thrombomodulin (TM/protein C/protein S anticoagulant pathway in modulating the thrombogenic properties of the endothelium. Endothelial cells (ECs) were placed in parallel-plate flow chambers and exposed to nonanticoagulated human blood at a venous wall shear rate (50 s-1). Fibrin deposition on resting ECs treated with a control IgG1 was negligible. In contrast, a significant amount of fibrin deposited when TM expression was specifically suppressed by > 95% by preincubating ECs with an anti-TM IgG1. Similarly, fibrin deposited on interleukin 1-stimulated ECs, but the fibrin deposition was further increased threefold with anti-TM IgG1. Comparable results were found when ECs were perfused at 650 s-1. When TM surface activity was enhanced by 150% by treating ECs with active phorbol ester (4-phorbol 12-myristate 13-acetate; PMA), the deposition of fibrin was 30% lower than on ECs not pretreated with PMA. Finally, fibrin deposition on stimulated ECs was significantly higher in 11 untreated patients with well-characterized deficiencies of protein C or S or heterozygous factor V Leiden mutation than in 11 healthy individuals, and it was significantly correlated to basal plasma levels of thrombin-antithrombin complexes. Thus, this study underlines the central role of the TM/protein C/protein S pathway in modulating the thrombogenic status of resting and stimulated ECs and indicates that basal coagulation system markers may be helpful in monitoring patients presenting a disorder of this anticoagulant pathway.

Dendrimers as reactive modules for the synthesis of new structure-controlled, higher-complexity megamers (2000)

Abstract Dendrimers are macromolecular, nanoscale objects that are widely recognized as precise, mathematically defined, covalent core-shell assemblies. As such, they are composed of quantized numbers of atoms, monomers, and terminal functional groups relative to the respective shell levels (generations) surrounding their cores. Dendrimers have been referred to as molecular-level analogs of atoms. This perspective arises from their potential to function as precise macromolecular tectons (modules), suitable for the synthesis of structure-controlled complexity beyond dendrimers. We have termed this major new class of generic structures "megamers". Our group has now synthesized such "megamer complexity" in the form of both covalent and supra-macromolecular dendri-catenanes, dendri-macrocycles, dendri-clefts, and dendri-clusters. The covalent dendri-cluster subset of megamers has been coined "core-shell tecto(dendrimers)". New mathematically defined, covalent bonding rules for tecto(dendrimer) formation are consistent with sterically induced stoichiometry (SIS) predictions and have been verified experimentally.
Smart Messages: a system architecture for large networks of embedded systems (2005)

We propose a system architecture and a computing model, based on Smart Messages (SMs), for computation and communication in large networks of embedded systems. In this model, communication is realized by sending SMs in the network. These messages are comprised of code, which is executed at each hop in the path of the message, and data which the message carries in the network. The execution at each hop determines the next hop in the message's path - SMs are responsible for their own routing.

The importance of grain boundary morphology and cohesion on intergranular strength (1974)

The morphology and constituency at grain boundaries are important in determining the properties of a poly crystalline material. In the present work it is shown that sulphur contents greater than 20 at. ppm. can embrittle nickel and nickel-base superalloys when the sulphur segregates to the grain boundaries and reduces intergranular cohesive strength. Moreover, low ductility can occur in nickel-base superalloy structures with controlled impurity levels when high stress concentrations develop in the grain boundary regions, either because of massive grain boundary shear or because of concentrated slip near grain boundaries. Résumé La morphologie et la constitution des join ts de grains sont importantes pour la détermination des propriétés de matériaux poly cristallins. Dans cette étude les auteurs montrent que des concentrations de soufre supérieures à 20 ppm. at. peuvent fragiliser le nickel et des superalliages à base de nickel quand le soufre ségrège aux joints de grains et réduit la cohésion intergranulaire. De plus, dans les superalliages à concentration contrôlée d'impuretés, une faible ductilité peut apparaître quand de fortes concentrations de contraintes se développent aux joints de grains soit sous l'effet de cisaillement massif du joint soit sous l'effet d'un glissement concentré aux joints.
High expression in leaves of the zinc hyperaccumulator <i>Arabidopsis halleri</i> of <i>AhMHX</i>, a homolog of an <i>Arabidopsis thaliana</i> vacuolar metal/proton exchanger (2006)

Zn hyperaccumulator plants sequester Zn into their shoot vacuoles. To date, the only transporters implicated in Zn sequestration into the vacuoles of hyperaccumulator plants are cation diffusion facilitators (CDFs). We investigated the expression in Arabidopsis halleri of a homolog of AtMHX, an A. thaliana tonoplast transporter that exchanges protons with Mg, Zn and Fe ions. A. halleri has a single copy of a homologous gene, encoding a protein that shares 98% sequence identity with AtMHX. Western blot analysis with vacuolar-enriched membrane fractions suggests localization of AhMHX in the tonoplast. The levels of MHX proteins are much higher in leaves of A. halleri than in leaves of the non-accumulator plant A. thaliana. At the same time, the levels of MHX transcripts are similar in leaves of the two species. This suggests that the difference in MHX levels is regulated at the post-transcriptional level. In vitro translation studies indicated that the difference between AhMHX and AtMHX expression is not likely to result from the variations in the sequence of their 5' untranslated regions (5'UTRs). The high expression of AhMHX in A. halleri leaves is constitutive and not significantly affected by the metal status of the plants. In both species, MHX transcript levels are higher in leaves than in roots, but the difference is higher in A. halleri. Metal sequestration into root vacuoles was suggested to inhibit hyperaccumulation in the shoot. Our data implicate AhMHX as a candidate gene in metal accumulation or tolerance in A. halleri.
FTIR ANALYSIS OF IRRADIATED FOOD-GRADE PVC FILMS (2015)

This work aimed to investigate the influence of ionizing radiation (gamma radiation and accelerated electrons) at commercial doses of 1, 2 and 4 kGy on optical properties of PVC films used as food packaging. FTIR was carried out for range of 4000 to 400 cm-1 by direct measurement. Polyene formation was measured with spectrophotometry at wavelength of 400 nm. FTIR of irradiated samples reveals reduction of absorbance of carbon-hydrogen (methylene) and carbon-chloride bands suggesting PVC scission due to dehydrochlorination reactions. Furthermore, polyene formation demonstrated increase on irradiated samples because of scission reactions on food-grade PVC films. This observation confirms polymeric radiolysis mechanisms promoted by gamma-rays or accelerated electrons.
Influence of Compact, Inorganic Surface Ligands on the Electrophoretic Deposition of Semiconductor Nanocrystals at Low Voltage (2018)

For electrophoretic deposition (EPD) to achieve its potential as a method for assembling functional semiconductors, it will be necessary to understand both what governs the threshold voltage for deposition and how to reduce that threshold. Herein we demonstrate that postsynthetic modification of the surface chemistry of all-inorganic copper zinc tin sulfide (CZTS) nanocrystals (NCs) enables EPD at voltages of as low as 4 V, which is a 3-fold or greater reduction over previous examples of nonoxide semiconductors. The chemical exchange of the original surfactant-based NC-surface ligands with selenide ions yields essentially bare, highly surface-charged NCs. Thus, both the electrophoretic mobility and electrochemical reactivity of these particles are increased, favoring deposition. In situ imaging of the reactor during deposition provides a quantitative measure of the electric field in the bulk of the reactor, yielding fundamental insight into the reaction mechanism and mass transport in the low-voltage regime. A crossover from mass-transport-limited to reaction-rate-limited EPD is observed. Under the latter conditions, the influence of gravity can result in boundary-layer instabilities that are severely deleterious to the uniformity of the deposited film, despite the gravitational stability of the colloids in the absence of electric fields. This knowledge is applied to deposit thick, uniform, and crack-free films without sintering, from stable, well-dispersed colloidal starting materials.
Auxiliary function based IVA using a source prior exploiting fourth order relationships (2013)

Independent vector analysis (IVA) can theoretically avoid the permutation ambiguity present in frequency domain independent component analysis by using a multivariate source prior to retain the dependency between different frequency bins of each source. The auxiliary function based independent vector analysis (AuxIVA) is a stable and fast update IVA algorithm which includes no tuning parameters. In this paper, a particular multivariate generalized Gaussian distribution source prior is therefore adopted to derive the AuxIVA algorithm which can exploit fourth order relationships to better preserve the dependency between different frequency bins of speech signals. Experimental results confirm the improved separation performance achieved by using the proposed algorithm.
