Factors influencing potential intralake colonization by Myriophyllum spicatum L.

Abstract A factorial experimental design was used to determine which of several factors influence Myriophyllum spicatum L. vegetative colonization success. Also, the relationship between total nonstructural carbohydrate (TNC) content, a measure of propagule vigor, and propagule success was detailed. Colonization success in terms of growth and mortality was best during late summer in shallow water on rich organic sediments. Light availability, temperature, and sediment nutrient levels were high during this period. The poorest colonization conditions occurred during early autumn. During this period mortality was highest in deep water in calcareous nutrient poor sediments. Also, naturally produced vegetative fragments grew better than artificially abscised meristems and had higher TNC concentrations. Low TNC levels increased mortality, but they had no effect on subsequent growth, suggesting that naturally produced fragments are more likely to survive the winter than artificial fragments.
Maximum throughput versus minimum queue: a Martingale approach

Abstract We consider a single-server service station at which a stream of customers arrive in accordance with a point process with a locally integrable deterministic intensity function and customer service times are independently and identically distributed. Customers arriving at the station may be dispatched to somewhere else or may be admitted to the queue of the station and waiting to be served. In this paper, martingale theory for point processes is applied to obtain the optimal admission policy that minimizes the expected fixed duration cost due to the difference between the queue size and the throughput of the station, where the throughput of the station is being defined as the total number of customers admitted to the queue for the period.
Transfer of organic carbon through marine water columns to sediments – insights from stable and radiocarbon isotopes of lipid biomarkers

Abstract. Compound-specific 13C and 14C compositions of diverse lipid biomarkers (fatty acids, alkenones, hydrocarbons, sterols and fatty alcohols) were measured in sinking particulate matter collected in sediment traps and from underlying surface sediments in the Black Sea, the Arabian Sea and the Ross Sea. The goal was to develop a multiparameter approach to constrain relative inputs of organic carbon (OC) from marine biomass, terrigenous vascular-plant and relict-kerogen sources. Using an isotope mass balance, we calculate that marine biomass in sediment trap material from the Black Sea and Arabian Sea accounted for 66–100% of OC, with lower terrigenous (3–8%) and relict (4–16%) contributions. Marine biomass in sediments constituted lower proportions of OC (66–90%), with consequentially higher proportions of terrigenous and relict carbon (3–17 and 7–13%, respectively). Ross Sea data were insufficient to allow similar mass balance calculations. These results suggest that, whereas particulate organic carbon is overwhelmingly marine in origin, pre-aged allochthonous terrigenous and relict OC become proportionally more important in sediments, consistent with pre-aged OC being better preserved during vertical transport to and burial at the seafloor than the upper-ocean-derived marine OC.
Malignant myopericytoma: expanding the spectrum of tumours with myopericytic differentiation.

Aims: The spectrum of tumours showing myopericytic differentiation is increasingly being defined and includes lesions such as myofibroma and infantile haemangiopericytoma. Here we seek to describe for the first time and clinicopathologically characterize examples of malignant myopericytoma. Methods and results: Five cases of malignant myopericytoma were identified in the authors' consultation files. Immunostains were performed and clinical information was obtained. Tumours arose in three females and two males (median age 67 years, range 19–81 years) on the neck, arm, thigh and foot. One patient presented with disseminated metastases. One patient had a prior history of multiple benign myopericytomas in the same location. Four patients developed metastases and three died within 1 year. Tumours were composed of highly mitotic myoid-appearing ovoid-to-spindle cells showing at least focally striking perivascular orientation resembling that seen in benign myopericytoma; three cases were focally fascicular and three showed thin-walled branching vessels. All tumours showed at least focally prominent positivity for smooth muscle actin. One case showed dot-like desmin positivity. Conclusions: In reporting examples of malignant myopericytoma, we further characterize and broaden the morphological spectrum of myopericytic neoplasms. Available data indicate that malignant myopericytomas are associated with aggressive clinical behaviour.
Equidecomposable quadratic regions

This article describes an algorithm that decides whether a region in three dimensions, described by quadratic constraints, is equidecomposable with a collection of primitive regions. When a decomposition exists, the algorithm finds the volume of the given region. Applications to the 'Flyspeck' project are discussed.
IDENTIFICATION AND ANALYSIS OF STEREOSELECTIVE DRUG INTERACTIONS WITH LOW DENSITY LIPOPROTEIN BY HIGH-PERFORMANCE AFFINITY CHROMATOGRAPHY

Columns containing immobilized low-density lipoprotein (LDL) were prepared for the analysis of drug interactions with this agent by high-performance affinity chromatography (HPAC). R/S-Propranolol was used as a model drug for this study. The LDL columns gave reproducible binding to propranolol over 60 h of continuous use in the presence of pH 7.4 0.067 M potassium phosphate buffer. Experiments conducted with this type of column through frontal analysis indicated that two types of interactions were occurring between R-propranolol and LDL, while only a single type of interaction was observed between S-propranolol and LDL. The first type of interaction, which was seen for both enantiomers, involved non-saturable binding; this interaction had an overall affinity (nK a) of 1.9 (±0.1) × 105 M−1 for R-propranolol and 2.7 (±0.2) × 105 M−1 for S-propranolol at 37 °C. The second type of interaction was observed only for R-propranolol and involved saturable binding that had an association equilibrium constant (K a) of 5.2 (±2.3) × 105 M−1 at 37 °C. Similar differences in binding behavior were found for the two enantiomers at 20 °C and 27 °C. This is the first known example of stereoselective binding of drugs by LDL or other lipoproteins. This work also illustrates the ability of HPAC to be used as a tool for characterizing mixed-mode interactions that involve LDL and related binding agents.
Laser Beam Physics

The experiment was conducted using a neody-mium glass laser modified for normal pulse operation. The energy density was varied from 850J/sq cm where no breakdown occurred to 5000J/sq cm where the threshold for breakdown was exceeded. The normal pulse duration was 600μS. Analysis of the ejected material was achieved by using a Hughes ionisation gauge placed in the path of the ejected material. Oscilloscope traces of the ionisation gauge output show that the gauge’ sees’ what is flying past it. There is good correlation between laser radiation, plasma radiation and ionisation gauge fluctuations. The ionisation gauge gave distinguishable signals for ions, electrons, and neutral particles ejected from the target surface.
NADH-FMN Oxidoreductase Activity and Iron Content of Organs from Riboflavin- and Iron-Deficient Rats

ARSTRACT NADH-FMN oxidoreductase has been proposed as an enzyme involved in the release of iron from ferritin. The effects of riboflavin and/or iron deficiencies and of dietary allopurinol on the activities of this enzyme and on the iron contents of liver, kidney and duodenum were investigated. Allopurinol, a xanthine oxidase inhibitor, did not affect organ enzyme activities nor iron contents. Riboflavin-deficient rats and irondeficient rats both had significantly lower organ enzyme activities and iron contents than controls. Organ enzyme activities and iron contents of rats fed a diet deficient in both iron and riboflavin were significantly lower than those of controls. After dietary iron and/or riboflavin repletion, organ enzyme activities and iron contents increased. Rats fed an iron-overload diet had enzyme activities similar to that of controls, but organ iron contents were significantly increased over those of controls. Effects of riboflavin and/or iron deficiencies in rats on NADH-FMN oxidoreductase activities and iron contents of liver, kidney and duodenum appeared to be reversible by riboflavin and/or iron supplementation. The data support the view that NADH-FMN oxidoreductase may be a controlling enzyme in iron release from ferritin. J. Nutr. 107; 739-745, 1977.
Measuring the maintainability of open-source software

An editorial in empirical software engineering suggested that open-source software projects offer a great deal of data that can be used for experimentation. These data include artifacts such as source code and defect reports. In this paper we show that sources of open-source maintenance data, such as defect-tracking systems, change logs, and source code, cannot, in general, be used for measuring maintainability. We further show that approaches such as using defect distributions and the average lag time to fix a defect can be equally unusable. We conclude that, despite the plethora of open-source maintenance data, it is extremely hard to find data for determining the maintainability of open-source software.
New lines of inquiry on the illness of susto.

The folk‐illness of susto has long captured the interest of anthropologists. A review of the literature reveals a multitude of competing ideas as to its biological basis, its epidemiological patterning, and why it persists as it does. The present essay offers not only a summation of much of the research done on fright‐sickness to date, but also suggests a number of new lines of inquiry that, when completed, will advance our understanding of this widely spread, yet still to be fully understood, ethnomedical disease category.
The Relationship of Severe Acute Respiratory Syndrome Coronavirus with Avian and Other Coronaviruses

In February 2003, a severe acute respiratory syndrome coronavirus (SARS-CoV) emerged in humans in Guangdong Province, China, and caused an epidemic that had severe impact on public health, travel, and economic trade. Coronaviruses are worldwide in distribution, highly infectious, and extremely difficult to control because they have extensive genetic diversity, a short generation time, and a high mutation rate. They can cause respiratory, enteric, and in some cases hepatic and neurological diseases in a wide variety of animals and humans. An enormous, previously unrecognized reservoir of coronaviruses exists among animals. Because coronaviruses have been shown, both experimentally and in nature, to undergo genetic mutations and recombination at a rate similar to that of influenza viruses, it is not surprising that zoonosis and host switching that leads to epidemic diseases have occurred among coronaviruses. Analysis of coronavirus genomic sequence data indicates that SARS-CoV emerged from an animal reservoir. Scientists examining coronavirus isolates from a variety of animals in and around Guangdong Province reported that SARS-CoV has similarities with many different coronaviruses including avian coronaviruses and SARS-CoV-like viruses from a variety of mammals found in live-animal markets. Although a SARS-like coronavirus isolated from a bat is thought to be the progenitor of SARS-CoV, a lack of genomic sequences for the animal coronaviruses has prevented elucidation of the true origin of SARS-CoV. Sequence analysis of SARS-CoV shows that the 5' polymerase gene has a mammalian ancestry; whereas the 3' end structural genes (excluding the spike glycoprotein) have an avian origin. Spike glycoprotein, the host cell attachment viral surface protein, was shown to be a mosaic of feline coronavirus and avian coronavirus sequences resulting from a recombination event. Based on phylogenetic analysis designed to elucidate evolutionary links among viruses, SARS-CoV is believed to have branched from the modern Group 2 coronaviruses, suggesting that it evolved relatively rapidly. This is significant because SARS-CoV is likely still circulating in an animal reservoir (or reservoirs) and has the potential to quickly emerge and cause a new epidemic.
Retrievals of nighttime electron density from Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) mission Global Ultraviolet Imager (GUVI) measurements

[1] In this work we will present a method for retrieving nighttime electron density profiles from OI 135.6 nm limb emissions measured by the Global Ultraviolet Imager (GUVI) aboard the Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) mission spacecraft. The primary mechanism for 135.6 nm radiance in the nighttime thermosphere is recombination of O+ ions, and the volume emission rate is approximately proportional to the square of the electron density. Herein we describe a two-step inversion method in which we first determine the volume emission rate as a function of altitude from the radiance measurements and then use the inferred volume emission rates to determine the electron density profile. There are two important factors that we have addressed in constructing the retrieval algorithms for this problem. First, the GUVI instrument was primarily designed for day side measurements. Consequently, the signal levels on the night side are very low, and our retrieval algorithms must therefore be able to function in regions where the signals are weak. Second, since we must take the square root of the volume emission rate, it must be everywhere positive in order for the electron density to be deduced. For this reason, we have imposed nonnegativity constraints (using the methods described by Menke [1989]) on what might otherwise be discrete linear retrievals of volume emission rate. After describing the retrieval method we present an error analysis and a preliminary comparison with coincident measurements by incoherent scatter radars (ISRs). In general, the retrieved electron densities from the GUVI data agree well with the ISR data, although more coincident measurements would increase our confidence in the resulting electron density profiles.
Anatomy of a Madison County (Illinois) Class Action: A Study of Pathology

If per capita class action filing rates were the same nationwide as they are in Madison County, Illinois there would have been over 42,000 class action filings in 2000. One reason for the county's popularity among class action lawyers is its reputation for the propensity of its judges to accommodate class action lawyers' interests. In this monograph, I focus on a single class action (Schuppert et al. v. Down et al.) filed in Madison County on behalf of hundreds of thousand of mostly elderly Americans who were the victims of a vast mass-marketing scheme conducted by James Blair Down ("Down"), a Canadian citizen. Ironically, if not tragically, the elderly victims of the scheme appear poised to become victims a second time - of "class action" justice in Madison County. A provisional settlement agreement is so abusive of the class's rights that it can only gain final judicial approbation from a court oblivious to the need to protect class members from self-interested behavior by its self-appointed class lawyers. Indeed, if there were an award for the most abusive class action settlement of the decade if not the century, this settlement would be an odds-on favorite to gain the prize. The only possible impediment is a unique confluence of events that is permitting public scrutiny of the settlement - scrutiny that has already had some effect on the judicial proceedings in Madison County.

Cetacean distribution and abundance in relation to oceanographic domains on the eastern Bering Sea shelf: 1999–2004

Abstract Visual line transect surveys for cetaceans were conducted on the eastern Bering Sea shelf in association with pollock stock assessment surveys aboard the NOAA ship Miller Freeman in June and July of 1999, 2000, 2002, and 2004. Transect survey effort ranged from 1188 km in 1999 to 3761 km in 2002. Fin whales ( Balaenoptera physalus ) were the most common large whale in all years except 2004 when humpback whales ( Megaptera novaeangliae ) were more abundant. Dall's porpoise ( Phocoenoides dalli ) were the most common small cetacean in all years. Abundance estimates were calculated by year for each oceanographic domain: coastal, middle, and outer/slope. The middle and outer/slope domains were divided into two strata (“north” and “south”) because of variable survey effort. The distribution and abundance of baleen whales changed between the earlier (colder) and later (warmer) survey years. Fin whales consistently occupied the outer shelf and secondarily the middle shelf, and their abundance was an order of magnitude greater in cold compared to warm years. Humpback whales “lived on the margin” of the northern Alaska Peninsula, eastern Aleutian Islands and Bristol Bay; their preferred habitat is possibly associated with areas of high prey availability due to nutrient upwelling and aggregation mechanisms. Minke whales ( Balaenoptera acutorostrata ) occur shoreward of fin whales in the outer and middle shelf and in coastal habitats along the Alaska Peninsula. The highest abundance for this species was observed in a cold (1999) year. No clear relationship emerged for odontocetes with regard to warm and cold years. Dall's porpoise occupied both outer and middle domains and harbor porpoise ( Phocoena phocoena ) were more common in middle and coastal domains. This study provided a unique, broad-scale assessment of cetacean distribution and abundance on the eastern Bering Sea shelf and a baseline for future comparisons.
Uncommon invasive fungal pathogens in the acquired immunodeficiency syndrome

This communication lists fungi reported to cause invasive infection in patients with AIDS. It excludes the well known and common fungi that infect these patients such as Candida, Cryptococcus, Histoplasma, Coccidioides and Aspergillus. It is likely that these less common fungal pathogens will be seen more frequently in the enlarging AIDS population as it is continuously exposed to many of these potentially opportunistic fungi.

Development of a RVFV ELISA that can distinguish infected from vaccinated animals

Background: Rift Valley Fever Virus is a pathogen of humans and livestock that causes significant morbidity and mortality throughout Africa and the Middle East. A vaccine that would protect animals from disease would be very beneficial to the human population because prevention of the amplification cycle in livestock would greatly reduce the risk of human infection by preventing livestock epizootics. A mutant virus, constructed through the use of reverse genetics, is protective in laboratory animal models and thus shows promise as a potential vaccine. However, the ability to distinguish infected from vaccinated animals is important for vaccine acceptance by national and international authorities, given regulations restricting movement and export of infected animals. Results: In this study, we describe the development of a simple assay that can be used to distinguish naturally infected animals from ones that have been vaccinated with a mutant virus. We describe the cloning, expression and purification of two viral proteins, and the development of side by side ELISAs using the two viral proteins. Conclusion: A side by side ELISA can be used to differentiate infected from vaccinated animals. This assay can be done without the use of biocontainment facilities and has potential for use in both human and animal populations.
Using impedance imaging to determine intracavitary probe location

A multielectrode intracavitary probe is investigated as a means of estimating endocardial potentials. A necessary component of this procedure is knowledge of the probe location within the cavity. A method of obtaining the location of the probe using impedance imaging techniques is presented. Current sources and sinks are applied at two to six probe electrodes, thus generating a set of measured probe potentials. A surface integral formulation is then used to obtain a set of calculated probe potentials. This surface integral formulation assumes a knowledge of the probe location, and a comparison of the calculated and measured probe surface potentials indicates the correctness of the assumed probe location. The process is then repeated for another assumed probe location and is continued until the space of the possible probe locations has been spanned. >

Relationship between kinetic stability and immunogenicity of HLA-DR4/peptide complexes

Immunodominant T cell epitopes from the autoantigen human cartilage glycoprotein 39 have previously been mapped in the context of HLA-DR*0401 and *0402, using mice expressing HLA-DR4 transgenes. We measured the dissociation rates of these epitopes from soluble recombinant DR*0401 and DR*0402 to assess the relationship between peptide/HLA-DR4 kinetic stability and immunogenicity. Experiments were performed at endosomal pH (5.5) and at cell surface pH (7), in the absence and presence of soluble recombinant HLA-DM (sDM). All (4/4) immunodominant peptide/HLA-DR complexes exhibit dissociation half-times of 1h to several days. In contrast, most (3/4) non-immunodominant complexes dissociate with half-times <30 min under at least one of these conditions. Interestingly, a complex which is stable except in the presence of HLA-DM at pH 5.5 is immunogenic only following peptide immunization, while a complex which is stable at acidic but not at neutral pH, is non-immunogenic following either whole protein or peptide immunization. These data indicate that kinetic stability of peptide/MHC complexes in vivo is a key determinant of immunogenicity.
Evaluation of Pelvic Floor Muscular Redistribution After Primary Closure of Classic Bladder Exstrophy by 3-Dimensional Magnetic Resonance Imaging

Purpose: We used 3-dimensional magnetic resonance imaging reconstruction to generate models of the pelvic floor musculature in classic bladder exstrophy, allowing for statistical analysis of changes seen in the anatomy after primary closure.Materials and Methods: Patients with classic bladder exstrophy underwent pelvic magnetic resonance imaging before and after primary closure. Contours of the levator ani were mapped and measured in 3-dimensional space. In addition, 2-dimensional angles and measurements were used to make a quantitative and qualitative analysis of the pelvic floor before and after closure.Results: A total of 19 cases of classic bladder exstrophy were included in the study, with 12 closed as newborns without osteotomy and 7 closed later with osteotomy. In both groups the pre-closure exstrophy pelvic floor in the axial plane was box-like and after closure it had a more inward rotation. The steepness and angulation of the levator ani muscle remained relatively unchanged in both groups. The l...
Transverse modes of a laser resonator with Gaussian mirrors.

Analytical methods are presented for transverse mode analysis of a laser resonator having spherical mirrors with a Gaussian reflectivity profile. The modes of this type of resonator have a form similar to that of the conventional Gaussian modes, but it is necessary to define an additional beam parameter to meet the self-consistency requirement for resonator modes. Stability of both the conventional complex beam parameter and the additional parameter is discussed. It is predicted mathematically that small perturbations in the new beam parameter will cause the intensity profile of the higher-order modes to evolve into that of the fundamental mode. Mode losses and discrimination are also discussed. The results may be useful in the design of regenerative laser amplifiers.
The Movement Precuing Technique: Assumptions, Applications, and Extensions

The movement precuing technique is designed to reveal the major information-processing steps that lead up to the execution of voluntary movements. The main idea in the technique is to supply the subject with partial information about the defining characteristics of a motor response and then observe how long it takes the subject to perform the response when its corresponding reaction signal is presented. On the assumption that the time to perform the response includes the time to specify those parameters that were not precued in advance, times to perform the response in different precue conditions can be used to find out whether its defining parameter values are specified in a fixed or variable order, serially or in parallel, etc. This chapter reviews the studies that have utilized the movement precuing technique. These studies have focused on aimed hand movements, finger movements, and aimed foot movements. A common finding of the studies is that the parameters of movements can be specified in a variable rather than fixed order and serially rather than in parallel, although some notable exceptions have been found. Much of the chapter is concerned with methodological variations of the precuing technique which a number of investigators have introduced.

Phenotypic Properties of Scaffold-Based Signaling Paradigms

Scaffold proteins are key components of signaling networks, recruiting and organizing other signaling proteins. Certain scaffolds have been extensively characterized and a number of hypotheses exist regarding general scaffold functions, including the linearization of dose-response behavior and the mediation of feedback. Despite intense investigation, however, we lack a complete understanding of how scaffolds might influence signal transduction. The goal of this work is to systematically determine how various properties of signaling cascades are impacted in the presence or absence of scaffold proteins. Using rule-based modeling languages, we constructed three basic models of signaling based loosely on the network structure of the yeast pheromone signaling cascade. The first model lacks a scaffold; this solution cascade involves a series of Goldbeter-Koshland covalent modification cycles where each activated substrate is the kinase for a subsequent substrate. The second, machine, model contains a scaffold that acts as a nucleation point for the hierarchical assembly of kinases into a discrete multi-subunit signaling complex. Finally, the ensemble model contains a scaffold to which kinases bind independently. This ensemble network therefore exhibits considerably more combinatorial complexity in terms of the numbers of possible signaling species compared to the others. We performed a comparative analysis of these three paradigms, and found significant phenotypic differences. Notably, scaffold-based models exhibited far less noise as cascade depth increases. Furthermore, only machine-like models are capable of preventing crosstalk in instances where two pathways share components. More generally, we observed that a machine-like cascade generally offers greater functional robustness, though at the cost of evolutionary plasticity and time to signal response. The evolution of scaffold proteins, and the rules that govern the assembly of signaling complexes, has likely been driven by the distinct functional roles that scaffold-based signaling complexes can play.
Contributing to the Library Student Employee Experience: Perceptions of a Student Development Program

Abstract Academic libraries are in a unique position to evolve student employment into being more than merely a part-time job and to contribute to students' academic and personal success. Library student employees at the University of Nevada, Las Vegas were surveyed to determine if their participation in a co-curricular workshop series added value to their academic, professional and personal lives. The study shows statistically significant relationships between class standing and level of agreement that workshops provided students with information and/or skills that will help them in a job after college and in their day to day life outside of work and school. The results of this study indicate that students find value in having opportunities to develop academic, professional, and life skills while being employed part-time. Potential future research studies are discussed, including the impact of such a program on student retention, progression, and completion.
The disintegration of Kuanping Group in North Qinling orogenic belts and Neo-proterozoic N-MORB

Kuangping Group located in North Qinling orogenic belt which consists chiefly of metabasalts and meta-sedimentary.A new LA-ICPMS zircon U-Pb age of metabasalt of Kuanping Group is presented and gives a weighted mean 207Pb/206Pb age of 943Ma which in the Neo-proterozoic time.However,the meta-sedimentary of Kuanping Group is limited to that in Early Phanerozoic time,but the Proterozoic,as previously considered.Therefore,this indicate that the two types of rock is not a continuous stratigraphic unit,protoliths of metabasalts were tholeiitic basalts with N-MORB geochemical characteristics,which represents a dismembered ophiolite and indicate a remnants of Greenville orogeny in the North Qinling orogenic belts.

BGP is the inter-domain routing protocol widely used in the Internet today. And the stability of it has become an important problem that limits the development of Internet. The simulation system of BGP is most primary means to research the stability of BGP. This paper presents the design and implementation of a BGP simulation that takes full advantage of many technique characteristics provided by technique of object-oriented such as encapsulation, inheritance and polymorphism etc. Therefore, this simulation system has high scalability and maintainability.
Use of Collagen Extracellular Matrix Dressing for the Treatment of a Recurrent Venous Ulcer in a 52-Year-Old Patient.

Case This case study describes treatment for a 52-year-old man with a recurrent venous leg ulcer using a collagen dressing with extracellular matrix. Background The patient was admitted to the wound care service for a 3-week-old recurrent venous ulcer. Treatment included application of a collagen dressing with extracellular matrix twice weekly or as needed by the patient; application of a secondary dressing (4 × 4 gauze); and coverage with an expandable netting or gauze using a conforming stretch gauze bandage and latex-free dressing retention tape. Conclusion The initial venous leg ulcer in this patient required 10 weeks to achieve closure. Ninety-eight percent resolution of the recurrent ulcer had occurred within 4 weeks of treatment, with complete closure at 7 weeks. The average healing time for recurrent venous ulcers is reported in the literature to be longer than initial venous ulcers. In the case provided, collagen ECM dressings promoted complete wound healing in 49 days.

It is necessary to take effective prevention and control measures to prevent and control circulatory system diseases,malignant neoplasms,and respiratory diseases,so as to enhance the life quality for the elderly.
Macrophage tropism of feline leukemia virus (FeLV) of subgroup-C and increased production of tumor necrosis factor-alpha by FeLV-infected macrophages.

Erythroid aplasia is induced in cats by feline leukemia virus (FeLV) of subgroup C but not by FeLV of subgroup A. In an investigation of the role of macrophages in FeLV-C-induced diseases, the concentrations of FeLV and tumor necrosis factor-alpha (TNF-alpha) were compared between feline peritoneal macrophages incubated with FeLV of subgroup A or C. FeLV of both subgroups infected macrophages, but expression of FeLV-C was 21-fold higher than FeLV-A in peritoneal macrophages (P = .004). The supernatants of FeLV-C-inoculated macrophage cultures contained significantly higher levels of TNF-alpha (70 +/- 14 U/mL) at 72 hours postincubation compared with FeLV-A-inoculated (38 +/- 8 U/mL) and uninoculated (31 +/- 8 U/mL) cultures. Moreover, a positive correlation was shown between cell-associated FeLV surface glycoprotein gp70 and TNF-alpha expression in FeLV-C-infected macrophages by immunofluorescence (r = .6; P = .001), measured with a computer-assisted, laser-based digital imaging system. The addition of TNF-alpha to a uniform population of FeLV-infected cells (feline embryonic fibroblasts) caused an enhancement of viral expression (P < .05). These results indicate that FeLV-C has tropism for macrophages, FeLV expression is positively correlated with TNF-alpha expression in macrophages, and TNF-alpha enhances FeLV replication in fibroblasts. We suggest that FeLV-C infection of macrophages and secretion of TNF-alpha may be important in hematopoietic suppression in FeLV-C-infected cats.
Lysine-Specific Histone Demethylases in Normal and Malignant Hematopoiesis.

The epigenetic control of gene expression is central to the development of the hematopoietic system and the execution of lineage-specific transcriptional programs. During the last 10 years, mounting evidence has implicated the family of lysine-specific histone demethylases as critical regulators of normal hematopoiesis, whereas their deregulation is found in a broad spectrum of hematopoietic malignancies. Here, we review recent findings on the role of these enzymes in normal and malignant hematopoiesis and highlight how aberrant epigenetic regulation facilitates hematopoietic cell transformation through subversion of cell fate and lineage commitment programs.
Quantifying the Grimm Corpus: Transgressive and Transformative Bodies in the Grimms' Fairy Tales

What do bodies mean in fairy tales? Donald Haase’s engagement with the Grimms’ fairy tales has offered some hints, ranging from his attention to feminist scholarship on the Grimms to his multifaceted review of recent Grimm scholarship that addresses various meanings of bodies in the language and translation of their tales. Inspired by Haase’s work and encouragement, I created a database that lists every mention or description of a body in the Grimms’ tales and in five other European tale collections. I detailed the results of this quantitative investigation in my dissertation, generally treating all the tale collections as part of one large corpus. In this essay, however, to add to the conversation that Haase has generated and curated, I refilter the data to solely examine which body parts (nouns, adjectives, and actions) appear in the Grimm tales. A major thematic focus is transgression and transformation, especially their gendered dimensions.
Effect of high AC magnetic field on magnetic nanoparticles for magnetic hyperthermia and radiation/chemotherapy applications

Particularly for applications such as radiation therapy and chemotherapy, magnetically induced heating, or magnetic hyperthermia, is of great importance. This study presents a relatively simple setup that generates controlled and constant heating temperatures of 47C and 53C, well in excess of required temperatures for mild hyperthermia (42C). The heating elements used are superparamagnetic nanoparticles with Curie temperature of 47C and 53C, placed in an AC B field. The nanoparticles could be used as thermo-seeds that penetrate deep into a tumor, making the chemotherapy or radiation treatment much more effective.

Relations Between Children’s Levels of Responsiveness and Resistance, Maternal Interaction Behaviors, and Children’s Social Behaviors With Peers in School

ABSTRACTChildren’s peer relationships have their origins in family relationships. The present study focuses on the relative importance of children’s levels of responsiveness and/or resistance during mother-child interactions and tests a model of the direct and indirect relations between mother interaction behaviors and children’s social behaviors with peers. Findings indicated that children of mothers who were more controlling were likely to be more controlling and dominant in their relationships with peers. Also, mothers’ impositions were related to children’s dominant behavior with peers. Children’s level of responsiveness toward mothers moderated the effects of mothers’ cohesiveness in relation to children’s prosocial behaviors with peers. Children with high level of responsiveness toward their mothers’ cohesiveness were more likely to display prosocial behaviors among peers. Finally, the relation of mothers’ autonomy support on children’s leadership was moderated by either the child’s responsiveness o...
Choices About Attorney Fee-Shifting Laws: Further Substance/Procedure Problems under Erie and Elsewhere

Many statutes and rules operating in courts in the United States permit or mandate the shifting of attorney's fees in civil litigation. The erosion of the so-called American Rule on attorney's fees is found in laws that may be characterized as substantive or procedural. Proper characterizations should be founded on the rationales underlying the laws, as with promoting certain claims like civil rights violations (substantive) and with deterring attorney and party misconduct during civil litigation (procedural). These characterizations must be made in three settings: (1) Erie cases (i.e., a state law claim in a federal court); (2) choice of state law cases (i.e., an Illinois court hears a Wisconsin law claim); and (3) choice of who makes written laws within a state (i.e., legislature regulates conduct between parties leading to claims, while high court regulates attorney and party conduct during civil claim resolution in court). These characterizations have been made difficult by the unfortunate language in footnote 31 in Alyeska Pipeline Service Co., wherein the U.S. Supreme Court said that in diversity cases in the federal courts, "usually" state laws on recoveries of attorney's fees should be followed where those laws reflect "a substantial policy of the state."
Successful use of family‐based therapy interventions for uncontrolled type 1 diabetes in an adolescent

Adolescents with type 1 diabetes mellitus (T1DM) are at increased risk for poor treatment adherence and glycaemic lability. Parental involvement in a youth's diabetes regimen is associated with better outcomes, yet supported treatments may be inaccessible due to limited community resources and financial constraints. Furthermore, existing interventions emphasise a collaborative effort between family members, which may not be effective with youth with particular vulnerabilities. Similarities between T1DM and anorexia nervosa prompted our use of modified family-based therapy (FBT) with a 16-year-old male with poor glycaemic control. FBT-guided strategies were brief and implemented by a family medicine physician at routine visits. Medical symptoms dramatically improved over a four-month period, demonstrating that FBT tailored to T1DM warrants further investigation for youth with poor treatment adherence.

Licensure or License?: Prospects for Occupational Deregulation

Occupational licensing in the US has grown rapidly in recent decades. Over most of this period, there has been little concern over, and scant legislative attention directed to, this phenomenon. Recently, however, concerns have arisen about the extent, the costs, and the job-destroying nature associated with the licensing of many occupations. Since 2011 twelve states have formulated legislative proposals dealing with occupational deregulation. Do these twelve state attempts share any common characteristics? We find that such initiatives have tended so far to arise in states with Republican majorities in the state House or Senate, as well as in states with lower percentages of minority populations and of low-income occupations that are currently licensed. Even so, these attempts have so far failed to result in many occupations being deregulated.

THE ENGLISH BLENDING WORDS IN INDONESIAN’S NEWSPAPERS

Blending offers a unique and unusual character which is frequently used by mass because of its creativity and this study aims to figure out the pattern of English blending words in Indonesian’s newspaper created and the meanings of those blending words. The study found that the complex words shows the pattern. The pattern of those analyzed complex words are categorized into AB + CD =AD. These patterns are based on Plag’s theory about blending words. The meaning of those complex words was built based on the first and the second words. It follows the pattern of AD, namely the first term (A) and the last term (D) are combined. The twenty blending words discussed are not common in English itself. It is because these English complex words have been domesticated by Indonesian’s terms.
Social support predicts self-care confidence in patients with heart failure.

Background:Self-care for patients with heart failure includes engaging in behaviours that maintain medical stability and manage problematic symptoms, as well as the confidence in one’s ability to carry out such behaviours. Given the social context of self-care behaviours in heart failure, there has been increasing interest in social support as a predictor of self-care.Aim:The goal of the present study was to examine the role of social support in self-care across time for persons with heart failure.Methods:Using data from an observational study of patients with chronic heart failure (n = 280), we examined the role of three types of support – instrumental support, emotional support and assistance with self-care – in the longitudinal course of self-care maintenance, management and confidence. Self-report questionnaire data were collected at baseline and at three and six months later.Results:We found that instrumental and emotional support predicted better self-care confidence on average and that self-care co...
Developments in Geotechnical Earthquake Engineering in Recent Years: 2012

Several significant developments have occurred in experimental as well analytical techniques for analyzing the problems associated with geotechnical earthquake engineering. The research activity following the Niigata and Alaska earthquakes in 1964 has led to better understanding of the liquefaction problem. The problems associated with the dynamic loading of soils include but are not limited to dynamic soil properties, liquefaction of soils, design of shallow and deep foundations in non-liquefying and liquefying soils, design of retaining structures, stability of slopes, design of foundations for machines and vibratory equipment, and man-made vibrations. This chapter presents the recent and significant developments in the areas of liquefaction, stability of rigid retaining structures, shallow foundations, and pile foundations.
Viscous Interfacial Motion: Analysis and Computation

We consider the interfacial flows between two viscous incompressible fluids. After formulating the mathematical framework, we first present analytical solutions to the linearized problem, and discuss some results from linear asymptotic analysis. We then describe a numerical method for computing the nonlinear motion which ensures a high accuracy on and near the moving interface. Simulation results on viscous Stokes waves are presented to demonstrate the advantages of this method. In addition, as an example of nonlinear asymptotic study, we conduct a perturbation series analysis for Stokes waves with small viscosity, the results of which provide an analytical justification to the numerical observation.
