    Norepinephrine (NE) kinetics (plasma appearance rate, clearance, and forearm extraction) were measured during insulin-induced hypoglycemia in six healthy subjects. NE clearance did not change during hypoglycemia, indicating that the increase in plasma NE during hypoglycemia is due to an increased...... plasma appearance rate of NE. Forearm extraction of 3H-NE and of endogenous plasma epinephrine decreased significantly during hypoglycemia, probably due to an increase in regional blood flow....

  2. Insulin-induced CARM1 upregulation facilitates hepatocyte proliferation

    International Nuclear Information System (INIS)

    Previously, we reported that CARM1 undergoes ubiquitination-dependent degradation in renal podocytes. It was also reported that CARM1 is necessary for fasting-induced hepatic gluconeogenesis. Based on these reports, we hypothesized that treatment with insulin, a hormone typically present under the ‘fed’ condition, would inhibit gluconeogenesis via CARM1 degradation. HepG2 cells, AML-12 cells, and rat primary hepatocytes were treated with insulin to confirm CARM1 downregulation. Surprisingly, insulin treatment increased CARM1 expression in all cell types examined. Furthermore, treatment with insulin increased histone 3 methylation at arginine 17 and 26 in HepG2 cells. To elucidate the role of insulin-induced CARM1 upregulation, the HA-CARM1 plasmid was transfected into HepG2 cells. CARM1 overexpression did not increase the expression of lipogenic proteins generally increased by insulin signaling. Moreover, CARM1 knockdown did not influence insulin sensitivity. Insulin is known to facilitate hepatic proliferation. Like insulin, CARM1 overexpression increased CDK2 and CDK4 expression. In addition, CARM1 knockdown reduced the number of insulin-induced G2/M phase cells. Moreover, GFP-CARM1 overexpression increased the number of G2/M phase cells. Based on these results, we concluded that insulin-induced CARM1 upregulation facilitates hepatocyte proliferation. These observations indicate that CARM1 plays an important role in liver pathophysiology. - Highlights: • Insulin treatment increases CARM1 expression in hepatocytes. • CARM1 overexpression does not increase the expression of lipogenic proteins. • CARM1 knockdown does not influence insulin sensitivity. • Insulin-induced CARM1 upregulation facilitates hepatocyte proliferation

  4. A model of hemo-immunopoietic system adaptation to chronic low and intermediate radiation doses

    International Nuclear Information System (INIS)

    In this paper radiobiological conformities to natural laws of mice's hemoimmunopoiesis systems (lines CBA and C57 Bl/6) were investigated upon chronic internal with lowering power doses of β- irradiation 90Sr and external γ-irradiation with constant power. It was shown that determinative effects of long chronic irradiation become apparent upon development of chronic radioactive effect for experimental animals were observed upon γ-irradiation with power 6 cGy/day and more or under internal with lowering power dose of β-irradiation 90Sr introduced in concentration above 1.1 c Bq/g, that is correlated with appreciations of other author's made before, concerning 'critical' level of power doses for hemopoietic system. It was shown that reduction of medium length of animals' life correlates with dis-balance into a system and between systems' links of immuno- and hemopoiesis. Physiological balance of those systems was supplied genetically by determinative systems of sanogenesis, responded for forming adaptive processes in organism. Characteristics of positive and negative inter and outward systems' links, induced by additional radiation exposure and noticeably modified constitutive regulative mechanisms being before were made more exact. A model for adaptation of hemoimmunopoiesis system to chronic radiation exposure in a rate of low and intermediate power doses was modeled. A possibility of full or part regeneration of hemopoiesis depending on power dose and kind of irradiation was experimentally substantiated. (author)

  6. INSULIN INDUCES NITRIC OXIDE PRODUCTION IN BOVINEAORTIC ENDOTHELIAL CELLS

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Objective To examine the effects of insulin on cell proliferation, nitric oxide (NO) release and nitric oxide synthase (NOS) gene expression in bovine aortic endothelial cells ( BAEC ) . Methods The mi togenesis was assessed by MTT method; the products of NO in the culture media, by Griess reaction; and the levels of NOS mRNA in BAEC , by RT/PCR tech nique. Results BAEC were not responsive to the growth-promoting effects of insulin. Stimulation with insulin resulted a dose-dependent rise of NO in the culture supernatants 2h later, with a maximum at 12~24h and a decline at 24h. This rise was inhibited by an inhibitor of NOS (L-NAME). NOS mRNA increased slightly in BAEC without statistical significance. Conelu sion The study suggested that the insulin-induced NO release might be caused directly by NOS activation.

    Chronic chest pain can arise from a variety of etiologies. However, of those potential causes, the most life-threatening include cardiac disease. Chronic cardiac chest pain may be caused either by ischemia or atherosclerotic coronary artery disease or by other cardiac-related etiologies, such as pericardial disease. To consider in patients, especially those who are at low risk for coronary artery disease, are etiologies of chronic noncardiac chest pain. Noncardiac chest pain is most commonly related to gastroesophageal reflux disease or other esophageal diseases. Alternatively, it may be related to costochondritis, arthritic or degenerative diseases, old trauma, primary or metastatic tumors, or pleural disease. Rarely, noncardiac chest pain may be referred pain from organ systems below the diaphragm, such as the gallbladder. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. PMID:23542027

    Full Text Available Hepatic responsiveness to gluconeogenic substrates during insulin-induced hypoglycemia was investigated. For this purpose, livers were perfused with a saturating concentration of 2 mM glycerol, 5 mM L-alanine or 5 mM L-glutamine as gluconeogenic substrates. All experiments were performed 1 h after an ip injection of saline (CN group or 1 IU/kg of insulin (IN group. The IN group showed higher (P<0.05 hepatic glucose production from glycerol, L-alanine and L-glutamine and higher (P<0.05 production of L-lactate, pyruvate and urea from L-alanine and L-glutamine. In addition, ip injection of 100 mg/kg glycerol, L-alanine and L-glutamine promoted glucose recovery. The results indicate that the hepatic capacity to produce glucose from gluconeogenic precursors was increased during insulin-induced hypoglycemia.

    Microvascular recruitment in muscle is a determinant of insulin sensitivity. Whether perivascular adipose tissue (PVAT) is involved in disturbed insulin-induced vasoreactivity is unknown, as are the underlying mechanisms. This study investigates whether PVAT regulates insulin-induced vasodilation...... in muscle, the underlying mechanisms, and how obesity disturbs this vasodilation. Insulin-induced vasoreactivity of resistance arteries was studied with PVAT from C57BL/6 or db/db mice. PVAT weight in muscle was higher in db/db mice compared with C57BL/6 mice. PVAT from C57BL/6 mice uncovered insulin......-induced vasodilation; this vasodilation was abrogated with PVAT from db/db mice. Blocking adiponectin abolished the vasodilator effect of insulin in the presence of C57BL/6 PVAT, and adiponectin secretion was lower in db/db PVAT. To investigate this interaction further, resistance arteries of AMPKa2(+/+) and AMPKa2...

  13. Mechanical stretch augments insulin-induced vascular smooth muscle cell proliferation by insulin-like growth factor-1 receptor

    International Nuclear Information System (INIS)

    Insulin resistance and hypertension have been implicated in the pathogenesis of cardiovascular disease; however, little is known about the roles of insulin and mechanical force in vascular smooth muscle cell (VSMC) remodeling. We investigated the contribution of mechanical stretch to insulin-induced VSMC proliferation. Thymidine incorporation was stimulated by insulin in stretched VSMCs, but not in un-stretched VSMCs. Insulin increased 2-deoxy-glucose incorporation in both stretched and un-stretched VSMCs. Mechanical stretch augmented insulin-induced extracellular signal-regulated kinase (ERK) and Akt phosphorylation. Inhibitors of epidermal growth factor (EGF) receptor tyrosine kinase and Src attenuated insulin-induced ERK and Akt phosphorylation, as well as thymidine incorporation, whereas 2-deoxy-glucose incorporation was not affected by these inhibitors. Moreover, stretch augmented insulin-like growth factor (IGF)-1 receptor expression, although it did not alter the expression of insulin receptor and insulin receptor substrate-1. Insulin-induced ERK and Akt activation, and thymidine incorporation were inhibited by siRNA for the IGF-1 receptor. Mechanical stretch augments insulin-induced VSMC proliferation via upregulation of IGF-1 receptor, and downstream Src/EGF receptor-mediated ERK and Akt activation. Similar to in vitro experiment, IGF-1 receptor expression was also augmented in hypertensive rats. These results provide a basis for clarifying the molecular mechanisms of vascular remodeling in hypertensive patients with hyperinsulinemia. -- Highlights: → Mechanical stretch augments insulin-induced VSMC proliferation via IGF-1 receptor. → Src/EGFR-mediated ERK and Akt phosphorylation are augmented in stretched VSMCs. → Similar to in vitro experiment, IGF-1 receptor is increased in hypertensive rats. → Results provide possible mechanisms of vascular remodeling in hypertension with DM.

  17. Effect of insulin-induced hypoglycaemia on the central nervous system: evidence from experimental studies.

    2014-03-01

    Insulin-induced hypoglycaemia (IIH) is a major acute complication in type 1 as well as in type 2 diabetes, particularly during intensive insulin therapy. The brain plays a central role in the counter-regulatory response by eliciting parasympathetic and sympathetic hormone responses to restore normoglycaemia. Brain glucose concentrations, being approximately 15-20% of the blood glucose concentration in humans, are rigorously maintained during hypoglycaemia through adaptions such as increased cerebral glucose transport, decreased cerebral glucose utilisation and, possibly, by using central nervous system glycogen as a glucose reserve. However, during sustained hypoglycaemia, the brain cannot maintain a sufficient glucose influx and, as the cerebral hypoglycaemia becomes severe, electroencephalogram changes, oxidative stress and regional neuronal death ensues. With particular focus on evidence from experimental studies on nondiabetic IIH, this review outlines the central mechanisms behind the counter-regulatory response to IIH, as well as cerebral adaption to avoid sequelae of cerebral neuroglycopaenia, including seizures and coma.

    Cortical spreading depression (CSD) is characterized by reversible reduction of spontaneous and evoked electrical activity of the cerebral cortex. Experimental evidence suggests that CSD may modulate neural excitability and synaptic activity, with possible implications for long-term potentiation. Systemic factors like anesthetics and insulin-induced hypoglycemia can influence CSD propagation. In this study, we examined whether the post-CSD ECoG potentiation can be modulated by anesthetics and insulin-induced hypoglycemia. We found that awake adult rats displayed increased ECoG potentiation after CSD, as compared with rats under urethane+chloralose anesthesia or tribromoethanol anesthesia. In anesthetized rats, insulin-induced hypoglycemia did not modulate ECoG potentiation. Comparison of two cortical recording regions in awake rats revealed a similarly significant (pchloralose and tribromoethanol anesthesia modulate the post-CSD potentiation of spontaneous electrical activity in the adult rat cortex, and insulin-induced hypoglycemia does not modify this effect. Data may help to gain a better understanding of excitability-dependent mechanisms underlying CSD-related neurological diseases. PMID:25681772

  20. Insulin absorption and subcutaneous blood flow in normal subjects during insulin-induced hypoglycemia

    International Nuclear Information System (INIS)

    We studied the effects of insulin-induced hypoglycemia on the absorption of 10 U 125I-labeled soluble human insulin injected sc in the thigh in 10 normal subjects. The disappearance of 125I from the injection site was followed by external gamma-counting. Subcutaneous blood flow (ATBF) was measured concomitantly with the 133Xe washout technique. The plasma glucose nadir [mean, 2.0 +/- 0.1 (+/- SE) mmol/L] occurred at 33 +/- 3 min and resulted in maximal arterial plasma epinephrine concentrations of approximately 6 nmol/L. From 30 min before to 60 min after the glucose nadir the [125I]insulin absorption rate was depressed compared to that during normoglycemia. The first order disappearance rate constants were reduced by approximately 50% (P less than 0.01) during the first 30-min interval after the glucose nadir. During the same period ATBF increased by 100% (P less than 0.05). The results suggest that in normal subjects the absorption of soluble insulin from a sc depot is depressed in connection with hypoglycemia, despite considerably elevated ATBF

    Overweight and obesity are associated with hyperinsulinemia, insulin resistance, and a low-grade inflammation. Although hyperinsulinemia is generally thought to result from an attempt of the β-cell to compensate for insulin resistance, there is evidence that hyperinsulinaemia itself may contribute to the development of insulin resistance and possibly the low-grade inflammation. To test this hypothesis, U937 macrophages were exposed to insulin. In these cells, insulin induced expression of the proinflammatory cytokines IL-1β, IL-8, CCL2, and OSM. The insulin-elicited induction of IL-1β was independent of the presence of endotoxin and most likely mediated by an insulin-dependent activation of NF-κB. Supernatants of the insulin-treated U937 macrophages rendered primary cultures of rat hepatocytes insulin resistant; they attenuated the insulin-dependent induction of glucokinase by 50%. The cytokines contained in the supernatants of insulin-treated U937 macrophages activated ERK1/2 and IKKβ, resulting in an inhibitory serine phosphorylation of the insulin receptor substrate. In addition, STAT3 was activated and SOCS3 induced, further contributing to the interruption of the insulin receptor signal chain in hepatocytes. These results indicate that hyperinsulinemia per se might contribute to the low-grade inflammation prevailing in overweight and obese patients and thereby promote the development of insulin resistance particularly in the liver, because the insulin concentration in the portal circulation is much higher than in all other tissues.

    Brain glycogen is proposed to function under both physiological and pathological conditions. Pharmacological elevation of this glucose polymer in brain is hypothesized to protect neurons against hypoglycemia-induced cell death. Elevation of brain glycogen levels due to prior hypoglycemia is postulated to contribute to the development of hypoglycemia-associated autonomic failure (HAAF) in insulin-treated diabetic patients. This latter mode of elevating glycogen levels is termed "supercompensation." We tested whether brain glycogen supercompensation occurs in healthy, conscious mice after recovery from insulin-induced acute or recurrent hypoglycemia. Blood glucose levels were lowered to less than 2.2 mmol/liter for 90 min by administration of insulin. Brain glucose levels decreased at least 80% and brain glycogen levels decreased approximately 50% after episodes of either acute or recurrent hypoglycemia. After these hypoglycemic episodes, mice were allowed access to food for 6 or 27 hr. After 6 hr, blood and brain glucose levels were restored but brain glycogen levels were elevated by 25% in mice that had been subjected to either acute or recurrent hypoglycemia compared with saline-treated controls. After a 27-hr recovery period, the concentration of brain glycogen had returned to baseline levels in mice previously subjected to either acute or recurrent hypoglycemia. We conclude that brain glycogen supercompensation occurs in healthy mice, but its functional significance remains to be established. PMID:21259334

    Insulin-induced gene 2 (INSIG2) and its homolog INSIG1 encode closely related endoplasmic reticulum proteins that regulate the proteolytic activation of sterol regulatory element-binding proteins, transcription factors that activate the synthesis of cholesterol and fatty acids in animal cells. Several studies have been carried out to identify INSIG2 genetic variants associated with metabolic diseases. However, few data have been published regarding the regulation of INSIG2 gene expression. Two Insig2 transcripts have been described in rodents through the use of different promoters that produce different noncoding first exons that splice into a common second exon. Herein we report the cloning and characterization of the human INSIG2 promoter and the detection of an INSIG2-specific transcript homologous to the Insig2b mouse variant in human liver. Deletion analyses on 3 kb of 5′-flanking DNA of the human INSIG2 gene revealed the functional importance of a 350-bp region upstream of the transcription start site. Mutated analyses, chromatin immunoprecipitation assays, and RNA interference analyses unveiled the significance of an Ets-consensus motif in the proximal region and the interaction of the Ets family member SAP1a (serum response factor (SRF) accessory protein-1a) with this region of the human INSIG2 promoter. Moreover, our findings suggest that insulin activated the human INSIG2 promoter in a process mediated by phosphorylated SAP1a. Overall, these results map the functional elements in the human INSIG2 promoter sequence and suggest an unexpected regulation of INSIG2 gene expression in human liver. PMID:20145255

  6. Insulin-induced decrease in protein phosphorylation in rat adipocytes not explained by decreased A-kinase activity

    International Nuclear Information System (INIS)

    In isolated rat adipocytes, insulin inhibits lipolysis to a greater extent than would be predicted by the decrease in (-/+)cAMP activity ratio of cAMP-dependent protein kinase [A-kinase], from which it was speculated that insulin promotes the dephosphorylation of hormone-sensitive lipase. They have examined the phosphorylation state of cellular proteins under conditions of varying A-kinase activities in the presence and absence of insulin. Protein phosphorylation was determined by SDS-PAGE electrophoresis of extracts from 32P-loaded cells; glycerol and A-kinase activity ratios were measured in the cytosolic extracts from control, non-radioactive cells. Increased protein phosphorylation in general occurred over the same range of A-kinase activity ratios, 0.1-0.3, associated with increased glycerol release. The insulin-induced decrease in lipolysis was associated with a decrease in the 32P content of several proteins, an effect not explained by the modest reduction in A-kinase activity by insulin. This effect of insulin on protein phosphorylation was lost as the A-kinase activity ratios exceeded 0.5. The results suggest that insulin promotes the dephosphorylation of those adipocyte proteins which are subject to phosphorylation by A-kinase

    A case of chronic intermediate uveitis and associated classic snowbanking (pars planitis) with severe cystoid macular oedema probably due to Lyme borreliosis is reported. Despite a disease duration of 10 years the patient's ocular symptoms and visual acuity responded promptly to intravenous ceftriaxone treatment. This case demonstrates that periodic reevaluation of patients with intermediate uveitis is necessary to obtain a specific diagnosis which may include Lyme borreliosis.

    Full Text Available Introduction The prevalence and negative health effects of chronic diseases are disproportionately high among Hispanics, the largest minority group in the United States. Self-management of chronic conditions by older adults is a public health priority. The objective of this study was to examine 6-week differences in self-efficacy, time spent performing physical activity, and perceived social and role activities limitations for participants in a chronic disease self-management program for Spanish-speaking older adults, Tomando Control de su Salud (TCDS. Methods Through the Healthy Aging Regional Collaborative, 8 area agencies delivered 82 workshops in 62 locations throughout South Florida. Spanish-speaking participants who attended workshops from October 1, 2008, through December 31, 2010, were aged 55 years or older, had at least 1 chronic condition, and completed baseline and post-test surveys were included in analysis (N = 682. Workshops consisted of six, 2.5-hour sessions offered once per week for 6 weeks. A self-report survey was administered at baseline and again at the end of program instruction. To assess differences in outcomes, a repeated measures general linear model was used, controlling for agency and baseline general health. Results All outcomes showed improvement at 6 weeks. Outcomes that improved significantly were self-efficacy to manage disease, perceived social and role activities limitations, time spent walking, and time spent performing other aerobic activities. Conclusion Implementation of TCDS significantly improved 4 of 8 health promotion skills and behaviors of Spanish-speaking older adults in South Florida. A community-based implementation of TCDS has the potential to improve health outcomes for a diverse, Spanish-speaking, older adult population.

    The savings/investment process in capitalist economies is organized around financial intermediation, making them a central institution of economic growth. Financial intermediaries are firms that borrow from consumer/savers and lend to companies that need resources for investment. In contrast, in capital markets investors contract directly with firms, creating marketable securities. The prices of these securities are observable, while financial intermediaries are opaque. Why do financial inter...

    This paper develops a simple model of international trade with intermediation. We consider an economy with two islands and two types of agents, farmers and traders. Farmers can produce two goods, but in order to sell these goods in centralized (Walrasian) markets, they need to be matched with a trader, and this entails costly search. In the absence of search frictions, our model reduces to a standard Ricardian model of trade. We use this simple model to contrast the implications of changes in...

In all technical reproductions of images, such as printing processes, an image is taken from a negative matrix in order to realize multiple prints of the same representation. The most effective model of this procedure is photography: photographic images can easily be connected with their media forms to produce other, more complex forms, such as magazines, printed books, or films. Intermediate images in the form of matrices - sometimes transparent (e.g. in the light beam of a film projection, sometimes opaque - are required to transform one pictorial media form into another. Finally, for the digital matrix-image, there is no longer any difference between the matrix and the image: the matrix has become its own image, which can be linked to all other media forms.

    Full Text Available Intermediate uveitis (IU is described as inflammation in the anterior vitreous, ciliary body and the peripheral retina. In the Standardization of Uveitis Nomenclature (SUN working group′s international workshop for reporting clinical data the consensus reached was that the term IU should be used for that subset of uveitis where the vitreous is the major site of the inflammation and if there is an associated infection (for example, Lyme disease or systemic disease (for example, sarcoidosis. The diagnostic term pars planitis should be used only for that subset of IU where there is snow bank or snowball formation occurring in the absence of an associated infection or systemic disease (that is, "idiopathic". This article discusses the clinical features, etiology, pathogenesis, investigations and treatment of IU.

    1. The vascular effect of insulin in the mesenteric resistance blood vessel and the role of calcitonin generelated peptide (CGRP)-receptor in insulin-induced vascular responsiveness were investigated in rats. 2. The mesenteric vascular beds isolated from Wistar rats were perfused with Krebs solution, and perfusion pressure was measured with a pressure transducer. In preparations contracted by perfusion with Krebs solution containing methoxamine in the presence of guanethidine, the perfusion of insulin (from 0.1 to 3000 nM) caused a concentration-dependent decrease in perfusion pressure due to vasodilatation. The pD2 value and maximum relaxation (%) were 6.94+/-0.22 and 43.9+/-5.2, respectively. 3. This vasodilator response to insulin was unaffected by 100 nM propranolol (beta-adrenoceptor antagonist) plus 100 nM atropine (muscarinic cholinoceptor antagonist), 100 microM L-NG-nitroarginine (nitric oxide synthase inhibitor), 1 microM ouabain (Na+-K+ ATPase inhibitor), or 1 microM glibenclamide (ATP sensitive K+-channel inhibitor). 4. In preparations without endothelium, perfusion of insulin produced a marked vasodilatation. The pD2 value and maximum relaxation (%) were 7.62+/-0.21 and 81.0+/-4.6, respectively, significantly greater than in preparations with intact endothelium. 5. The vasodilator responses to insulin in the preparations without endothelium were significantly inhibited by CGRP[8 37], a CGRP receptor antagonist, whereas pretreatment with capsaisin, a toxin for CGRP-containing nerves, did not affect insulin-induced vasodilatation. 6. These results suggest that insulin induces non-adrenergic, non-cholinergic and endothelium-independent vasodilatation, which is partially mediated by CGRP receptors. PMID:9605576

    Dioxin exposure has been positively associated with human type II diabetes. Because lipophilic dioxins accumulate mainly in adipose tissue, this study aimed to determine if dioxins induce metabolic dysfunction in fat cells. Using 3T3-L1 cells as an in vitro model, we analyzed the effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), a model dioxin, on adipogenic differentiation, glucose uptake, and lipolysis. TCDD inhibited adipogenic differentiation, as determined by using oil droplet formation and adipogenic marker gene expression, including PPAR{gamma} (peroxisome proliferator-activated receptor {gamma}), C/EBP{alpha} (CCAAT/enhancer-binding protein {alpha}), and Glut4 (glucose transporter type 4). Effects of TCDD on glucose uptake were evaluated using fully differentiated 3T3-L1 adipocytes, revealing that TCDD significantly attenuated insulin-induced glucose uptake dose dependently. Inhibition of aryl hydrocarbon receptor (AhR) by {alpha}-naphthoflavone ({alpha}-NF), an AhR inhibitor, did not prevent the inhibitory effect of TCDD on glucose uptake, suggesting that TCDD attenuates insulin-induced glucose uptake in an AhR-independent manner. Effects of TCDD on lipolysis were determined using glycerol release assay. We found that TCDD had no marked effect on isoproterenol-induced glycerol release in fully differentiated 3T3-L1 adipocytes. These results provide in vitro evidence of TCDD's effects on fat cell metabolism, suggesting dioxin exposure in development of insulin resistance and type II diabetes.

    Prolonged food deprivation in mammals typically reduces glucose, insulin, and thyroid hormone (TH) concentrations, as well as tissue deiodinase (DI) content and activity, which, collectively, suppress metabolism. However, in elephant seal pups, prolonged fasting does not suppress TH levels; it is associated with upregulation of adipose TH-mediated cellular mechanisms and adipose-specific insulin resistance. The functional relevance of this apparent paradox and the effects of glucose and insulin on TH-mediated signaling in an insulin-resistant tissue are not well defined. To address our hypothesis that insulin increases adipose TH signaling in pups during extended fasting, we assessed the changes in TH-associated genes in response to an insulin infusion in early- and late-fasted pups. In late fasting, insulin increased DI1, DI2, and THrβ-1 mRNA expression by 566%, 44%, and 267% at 60 min postinfusion, respectively, with levels decreasing by 120 min. Additionally, we performed a glucose challenge in late-fasted pups to differentiate between insulin- and glucose-mediated effects on TH signaling. In contrast to the insulin-induced effects, glucose infusion did not increase the expressions of DI1, DI2, and THrβ-1 until 120 min, suggesting that glucose delays the onset of the insulin-induced effects. The data also suggest that fasting duration increases the sensitivity of adipose TH-mediated mechanisms to insulin, some of which may be mediated by increased glucose. These responses appear to be unique among mammals and to have evolved in elephant seals to facilitate their adaptation to tolerate an extreme physiological condition. PMID:26739649

    Intermediation is the activity of buying and selling simultaneously in one market. In this paper, intermediation in the market for an arbitrary good is derived from trade restrictions in a general equilibrium exchange model. The trade restrictions are given by a trade feasibility relation defined on the set of households, and they necessitate dropping the one price assumption of standard general equilibrium theory. It is shown that, in this setting, equilibria need not exist in spite of well-...

    The fluid flow of porous media petroleum reservoirs is affected by wettability. In general, North Sea sandstone reservoirs fall into the large group of intermediate wet state reservoirs having end point saturation, capillary pressure, and relative permeability properties. This study examined intermediate the wet state by dividing the wet group into three sub-classes defined as fractionally-wet (FW), mixed-wet large (MWL), and mixed-wet small (MWS). Wettability indices were used to group reservoir data into reservoirs with FW, MWL and MWS behaviour. The analysis of wettability data from several North Sea fields showed that 13 reservoirs have sufficient wettability data to determine the state of intermediate wettability. Five of the reservoirs were classified as MWL, 4 as FW and 4 as MWS. Fractional-wet rock was found to have a more robust wettability and cleaned cores maintained a non-water state, suggesting that wetting sites can be coupled to mineralogy in addition to adsorption/deposition of oil components that change the surface properties of the rock. MWS was found to maintain wettability after cleaning, but MWL cores became water wet after solvent cleaning. This study indicates that the type of intermediate wettability has an impact on the data structure required to develop reservoir models. Wettability was found to influence the share of relative permeability curves and the capillary pressure relations in a variety of intermediate wettability classifications. 23 figs.

    The article argues the importance of intermediality as a concept for research in mobile communication and media. The constant availability of several, partially overlapping channels for communication (texting, calls, email, Facebook, etc.) requires that we adopt an integrated view of the various...... communicative affordances of mobile devices in order to understand how people choose between them for different purposes. It is argued that mobile communication makes intermediality especially central, as the choice of medium is detached from the location of stationary media and begins to follow the user across...

  15. Effect of insulin on human skeletal muscle protein synthesis is modulated by insulin-induced changes in muscle blood flow and amino acid availability

    OpenAIRE

    Fujita, Satoshi; Rasmussen, Blake B.; Cadenas, Jerson G.; Grady, James J.; Volpi, Elena

    Insulin promotes muscle anabolism, but it is still unclear whether it stimulates muscle protein synthesis in humans. We hypothesized that insulin can increase muscle protein synthesis only if it increases muscle amino acid availability. We measured muscle protein and amino acid metabolism using stable-isotope methodologies in 19 young healthy subjects at baseline and during insulin infusion in one leg at low (LD, 0.05), intermediate (ID, 0.15), or high (HD, 0.30 mU·min−1·100 ml−1) doses.

    Understanding phenomena such as the recent financial crisis, and possible policy responses, requires the use of a macroeconomic framework in which financial intermediation matters for the allocation of resources. Neither standard macroeconomic models that abstract from financial intermediation nor traditional models of the "bank lending channel" are adequate as a basis for understanding the recent crisis. Instead we need models in which intermediation plays a crucial role, but in which interm...

Auditing reduces the intermediary’s rent and increases allocative efficiency.

  5. Intermediate neutron spectrum problems and the intermediate neutron spectrum experiment

    International Nuclear Information System (INIS)

    Criticality benchmark data for intermediate energy spectrum systems does not exist. These systems are dominated by scattering and fission events induced by neutrons with energies between 1 eV and 1 MeV. Nuclear data uncertainties have been reported for such systems which can not be resolved without benchmark critical experiments. Intermediate energy spectrum systems have been proposed for the geological disposition of surplus fissile materials. Without the proper benchmarking of the nuclear data in the intermediate energy spectrum, adequate criticality safety margins can not be guaranteed. The Zeus critical experiment now under construction will provide this necessary benchmark data

    Science.gov (United States)

    Schwedt, Todd J

    2014-01-01

    Chronic migraine is a disabling neurologic condition that affects 2% of the general population. Patients with chronic migraine have headaches on at least 15 days a month, with at least eight days a month on which their headaches and associated symptoms meet diagnostic criteria for migraine. Chronic migraine places an enormous burden on patients owing to frequent headaches; hypersensitivity to visual, auditory, and olfactory stimuli; nausea; and vomiting. It also affects society through direct and indirect medical costs. Chronic migraine typically develops after a slow increase in headache frequency over months to years. Several factors are associated with an increased risk of transforming to chronic migraine. The diagnosis requires a carefully performed patient interview and neurologic examination, sometimes combined with additional diagnostic tests, to differentiate chronic migraine from secondary headache disorders and other primary chronic headaches of long duration. Treatment takes a multifaceted approach that may include risk factor modification, avoidance of migraine triggers, drug and non-drug based prophylaxis, and abortive migraine treatment, the frequency of which is limited to avoid drug overuse. This article provides an overview of current knowledge regarding chronic migraine, including epidemiology, risk factors for its development, pathophysiology, diagnosis, management, and guidelines. The future of chronic migraine treatment and research is also discussed. PMID:24662044

  11. Intermediate ions in the atmosphere

    Science.gov (United States)

    Tammet, Hannes; Komsaare, Kaupo; Hõrrak, Urmas

    2014-01-01

    Intermediate air ions are charged nanometer-sized aerosol particles with an electric mobility of about 0.03-0.5 cm2 V- 1 s- 1 and a diameter of about 1.5-7.5 nm. Intensive studies of new particle formation provided good knowledge about intermediate ions during burst events of atmospheric aerosol nucleation. Information about intermediate ions during quiet periods between the bursts remained poor. The new mobility analyzer SIGMA can detect air ions at concentrations of mobility fractions of about 1 cm- 3 and enables studying intermediate ions during quiet periods. It became evident that intermediate ions always exist in atmospheric air and should be considered an indicator and a mediator of aerosol nucleation. The annual average concentration of intermediate ions of one polarity in Tartu, Estonia, was about 40 cm- 3 while 5% of the measurements showed a concentration of less than 10 cm- 3. The fraction concentrations in logarithmic 1/8-decade mobility bins between 0.1 and 0.4 cm2 V- 1 s- 1 often dropped below 1 cm- 3. The bursts of intermediate ions at stations separated by around 100 km appeared to be correlated. The lifespan of intermediate ions in the atmosphere is a few minutes, and they cannot be carried by wind over long distances. Thus the observed long-range correlation of intermediate ions is explained by simultaneous changes in air composition in widely spaced stations. A certain amount of intermediate ion bursts, predominantly of negative polarity, are produced by the balloelectric effect at the splashing of water drops during rain. These bursts are usually excluded when speaking about new particle formation because the balloelectric particles are assumed not to grow to the size of the Aitken mode. The mobility distribution of balloelectric ions is uniform in shape in all measurements. The maximum is located at a mobility of about 0.2 cm2 V- 1 s- 1, which corresponds to the diameter of particles of about 2.5 nm.

    2015-01-01

    In the domain of Nuclear reactions at intermediate energies, the QCD coupling constant $\\alpha_s$ is large enough ($\\sim$ 0.3 - 0.5) to render the perturbative calculational techniques inapplicable. In this regime the quarks are confined into colorless hadrons and it is expected that effective field theories of hadron interactions via exchange of hadrons, provide useful tools to describe such reactions. In this contribution we discuss applications of one such theory, the effective Lagrangian model, in describing the hadronic reactions at intermediate energies whose measurements are the focus of a vast international experimental program.

    Full Text Available Under hypoglycemic conditions, concomitant hyperinsulinism causes an apparent modification of hemoglobin (Hb which is manifested by its aggregation (Niketi} et al., Clin. Chim. Acta 197 (1991 47. In the present work the causes and mechanisms underlying this Hb modification were studied. Hemoglobin isolated from normal erythrocytes incubated with insulin was analyzed by applying 31P-spectrometry and lipid extraction and analysis. To study the dynamics of the plasma membrane during hyperinsulinism, a fluorescent lipid-analog was applied. In the presence of insulin, phosphatidylserine (PS, phosphatidylethanolamine (PE and cholesterol were found to bind to Hb. Lipid binding resulted in Hb aggregation, a condition that can be reproduced when phospholipids are incubated with Hb in vitro. Using a fluorescent lipid-analog, it was also shown that exposing erythrocytes to supraphysiological concentrations of insulin in vitro resulted in the internalization of lipids. The results presented in this work may have relevance to cases of diabetes mellitus and hypoglycemia.

  6. Branching of keratin intermediate filaments.

    Nafeey, Soufi; Martin, Ines; Felder, Tatiana; Walther, Paul; Felder, Edward

    2016-06-01

    Keratin intermediate filaments (IFs) are crucial to maintain mechanical stability in epithelial cells. Since little is known about the network architecture that provides this stiffness and especially about branching properties of filaments, we addressed this question with different electron microscopic (EM) methods. Using EM tomography of high pressure frozen keratinocytes, we investigated the course of several filaments in a branching of a filament bundle. Moreover we found several putative bifurcations in individual filaments. To verify our observation we also visualized the keratin network in detergent extracted keratinocytes with scanning EM. Here bifurcations of individual filaments could unambiguously be identified additionally to bundle branchings. Interestingly, identical filament bifurcations were also found in purified keratin 8/18 filaments expressed in Escherichia coli which were reassembled in vitro. This excludes that an accessory protein contributes to the branch formation. Measurements of the filament cross sectional areas showed various ratios between the three bifurcation arms. This demonstrates that intermediate filament furcation is very different from actin furcation where an entire new filament is attached to an existing filament. Instead, the architecture of intermediate filament bifurcations is less predetermined and hence consistent with the general concept of IF formation. PMID:27039023

  9. Role of Intermediate Filaments in Vesicular Traffic

    Directory of Open Access Journals (Sweden)

    Azzurra Margiotta

    2016-04-01

    Full Text Available Intermediate filaments are an important component of the cellular cytoskeleton. The first established role attributed to intermediate filaments was the mechanical support to cells. However, it is now clear that intermediate filaments have many different roles affecting a variety of other biological functions, such as the organization of microtubules and microfilaments, the regulation of nuclear structure and activity, the control of cell cycle and the regulation of signal transduction pathways. Furthermore, a number of intermediate filament proteins have been involved in the acquisition of tumorigenic properties. Over the last years, a strong involvement of intermediate filament proteins in the regulation of several aspects of intracellular trafficking has strongly emerged. Here, we review the functions of intermediate filaments proteins focusing mainly on the recent knowledge gained from the discovery that intermediate filaments associate with key proteins of the vesicular membrane transport machinery. In particular, we analyze the current understanding of the contribution of intermediate filaments to the endocytic pathway.

    2005-01-01

    A new method is proposed for synthesizing intermediate views from a pair of stereoscopic images. In order to synthesize high-quality intermediate views, the block matching method together with a simplified multi-window technique and dynamic programming is used in the process of disparity estimation. Then occlusion detection is performed to locate occluded regions and their disparities are compensated. After the projecton of the left-to-right and right-to-left disparities onto the intermediate image, intermediate view is synthesized considering occluded regions. Experimental results show that our synthesis method can obtain intermediate views with higher quality.

  19. Intermediate inflation from rainbow gravity

    CERN Document Server

    Barrow, John D

    2013-01-01

    It is possible to dualize theories based on deformed dispersion relations and Einstein gravity so as to map them into theories with trivial dispersion relations and rainbow gravity. This often leads to "dual inflation" without the usual breaking of the strong energy condition. We identify the dispersion relations in the original frame which map into "intermediate" inflationary models. These turn out to be particularly simple: power-laws modulated by powers of a logarithm. The fluctuations predicted by these scenarios are near, but not exactly scale-invariant, with a red running spectral index. These dispersion relations deserve further study within the context of quantum gravity and the phenomenon of dimensional reduction in the ultraviolet.

    Let $SU_X(n,L)$ be the moduli space of rank n semistable vector bundles with fixed determinant L on a smooth projective genus g curve X. Let $SU_X^s(n,L)$ denote the open subset parametrizing stable bundles. We show that if g>3 and n > 1, then the mixed Hodge structure on $H^3(SU_X^s(n, L))$ is pure of type ${(1,2),(2,1)}$ and it carries a natural polarization such that the associated polarized intermediate Jacobian is isomorphic J(X). This is new when deg L and n are not coprime. As a corollary, we obtain a Torelli theorem that says roughly that $SU_X^s(n,L)$ (or $SU_X(n,L)$) determines X. This complements or refines earlier results of Balaji, Kouvidakis-Pantev, Mumford-Newstead, Narasimhan-Ramanan, and Tyurin.

  1. Intermediate processes in nuclear reactions

    International Nuclear Information System (INIS)

    The main results presented here cannot be interpreted in terms of the direct reaction model or the statistical models and one can more or less explicitely use some nuclear configurations for their interpretation. The first chapter deals with the so-called second order intermediate structures observed in the elastic and inelastic proton scattering on 66Zn and 70Ge targets in the energetic regions of some isobaric analog resonances. A formal theory for their interpretation is developed and the comparison with the experimental data is presented. New experimental results on the resonant structures observed in the elastic and inelastic scattering of 12C on 24Mg are presented in the second chapter. Detailed statistical analysis and their interpretation is presented too. Charge equilibration in deep inelastic collisions is the main subject of the third chapter. The experimental results obtained by the 98Mo + 154Sm collision at 12 MeV/n, a quantum treatment of a damped harmonic oscillator and the comparison with the experimental data are given. In the last chapter, some results on the existence of two other processes which could candidate to be involved in the main topic are presented. Those processes are: the fast fragmentation and preequilibrium charged particles emission. All these processes originate in the excitation of some simple configurations which can be seen on ''doorway'' states (''Hallway'' in the case of the second intermediate structures). The coupling of these states to other more complicated excitation modes of the nuclei and to outgoing channel=gives the possibility to study the nuclear dynamics. This justifies the interest for their detailed theoretical and experimental investigations. (author)

    This paper considers the optimal taxation of savings intermediation and payment services in a dynamic general equilibrium setting, when the government can also use consumption and income taxes. When payment services are used in strict proportion to final consumption, and the cost of intermediation services is fixed and the same across firms, the optimal taxes are generally indeterminate. But, when firms differ exogenously in the cost of intermediation services, the tax on savings intermediati...

  6. Experiments in intermediate energy physics

    Dehnhard, D.

    2003-02-28

    Research in experimental nuclear physics was done from 1979 to 2002 primarily at intermediate energy facilities that provide pion, proton, and kaon beams. Particularly successful has been the work at the Los Alamos Meson Physics Facility (LAMPF) on unraveling the neutron and proton contributions to nuclear ground state and transition densities. This work was done on a wide variety of nuclei and with great detail on the carbon, oxygen, and helium isotopes. Some of the investigations involved the use of polarized targets which allowed the extraction of information on the spin-dependent part of the triangle-nucleon interaction. At the Indiana University Cyclotron Facility (IUCF) we studied proton-induced charge exchange reactions with results of importance to astrophysics and the nuclear few-body problem. During the first few years, the analysis of heavy-ion nucleus scattering data that had been taken prior to 1979 was completed. During the last few years we created hypernuclei by use of a kaon beam at Brookhaven National Laboratory (BNL) and an electron beam at Jefferson Laboratory (JLab). The data taken at BNL for a study of the non-mesonic weak decay of the A particle in a nucleus are still under analysis by our collaborators. The work at JLab resulted in the best resolution hypernuclear spectra measured thus far with magnetic spectrometers.

    The theme that unites the sometimes seemingly disparate experiments undertaken by the Bonner Lab Medium Energy Group is a determination to understand in detail the many facets and manifestations of the strong interaction, that which is now referred to as nonperturbative QCD. Whether we are investigating the question of just what does carry the spin of baryons, or the extent of the validity of the SU(6) wavefunctions for the excited hyperons (as will be measured in their radiative decays in our CEBAF experiment), or questions associated with the formation of a new state of matter predicted by QCD (the subject of our BNL experiments E810, E854, as well as our approved experiment at RHIC), -- all these projects share this common goal. Our other experiments represent different approaches to the same broad undertaking. LAMPF E1097 will provide definitive answers to the question of the spin dependence of the inelastic channel of pion production in the n-p interaction. FNAL E683 may well open a new field of investigation in nuclear physics: that of just how quarks and gluons interact with nuclear matter as they transverse nuclei of different sizes. In most all of the experiments mentioned above, the Bonner Lab Group is playing major leadership roles as well as doing a big fraction of the hard work that such experiments require. We use many of the facilities that are unavailable to the intermediate energy physics community and we use our expertise to design and fabricate the detectors and instrumentation that are required to perform the measurements which we decide to do.

    2016-05-18

    Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in China. The Barcelona Clinic Liver Cancer (BCLC) staging system is regarded as the gold standard staging system for HCC, classifying HCC as early, intermediate, or advanced. For intermediate HCC, trans-catheter arterial chemoembolization (TACE) is recommended as the optimal strategy by the BCLC guideline. This review investigates whether liver resection is better than TACE for intermediate HCC. Based on published studies, we compare the survival benefits and complications of liver resection and TACE for intermediate HCC. We also compare the survival benefits of liver resection in early and intermediate HCC. We find that liver resection can achieve better or at least comparable survival outcomes compared with TACE for intermediate HCC; however, we do not observe a significant difference between liver resection and TACE in terms of safety and morbidity. We conclude that liver resection may improve the short- and long-term survival of carefully selected intermediate HCC patients, and the procedure may be safely performed in the management of intermediate HCC.

  10. Intermediate energy nuclear data for applications

    International Nuclear Information System (INIS)

    A comprehensive review of the data needs for various applications was performed by the participants of the meeting. The status of compilation and evaluation of the needed data in the intermediate energy range of incident particles was discussed. The following broad application areas were identified and considered by the participants: intermediate energy nuclear data needed for accelerators; intermediate energy nuclear data needed for space applications; intermediate energy nuclear data for medical applications. The role of nuclear model calculations in data evaluations in this energy range was considered. The possibilities of existing model codes were considered from the point of view of reliability, accuracy, cost of computer time, availability to specialists in the Member States. The Meeting presentations were divided into the following three sessions: Nuclear data needs in the intermediate energy range (6 papers), Progress of nuclear data computations and evaluations in the intermediate energy range (6 papers) and Progress of experimental data measurements in the intermediate energy range. A separate abstract was prepared for each paper. The ways of further improvement of the status of nuclear data in the intermediate energy range were discussed and the results of these discussions can be found in the conclusions and recommendations of this meeting.

  17. Genetic association analysis of complex diseases incorporating intermediate phenotype information.

    Directory of Open Access Journals (Sweden)

    Yafang Li

    Full Text Available Genetic researchers often collect disease related quantitative traits in addition to disease status because they are interested in understanding the pathophysiology of disease processes. In genome-wide association (GWA studies, these quantitative phenotypes may be relevant to disease development and serve as intermediate phenotypes or they could be behavioral or other risk factors that predict disease risk. Statistical tests combining both disease status and quantitative risk factors should be more powerful than case-control studies, as the former incorporates more information about the disease. In this paper, we proposed a modified inverse-variance weighted meta-analysis method to combine disease status and quantitative intermediate phenotype information. The simulation results showed that when an intermediate phenotype was available, the inverse-variance weighted method had more power than did a case-control study of complex diseases, especially in identifying susceptibility loci having minor effects. We further applied this modified meta-analysis to a study of imputed lung cancer genotypes with smoking data in 1154 cases and 1137 matched controls. The most significant SNPs came from the CHRNA3-CHRNA5-CHRNB4 region on chromosome 15q24-25.1, which has been replicated in many other studies. Our results confirm that this CHRNA region is associated with both lung cancer development and smoking behavior. We also detected three significant SNPs--rs1800469, rs1982072, and rs2241714--in the promoter region of the TGFB1 gene on chromosome 19 (p = 1.46×10(-5, 1.18×10(-5, and 6.57×10(-6, respectively. The SNP rs1800469 is reported to be associated with chronic obstructive pulmonary disease and lung cancer in cigarette smokers. The present study is the first GWA study to replicate this result. Signals in the 3q26 region were also identified in the meta-analysis. We demonstrate the intermediate phenotype can potentially enhance the power of complex

    Full Text Available Chronic urticaria (CU is a disturbing allergic condition of the skin. Although frequently benign, it may sometimes be a red flag sign of a serious internal disease. A multitude of etiologies have been implicated in the causation of CU, including physical, infective, vasculitic, psychological and idiopathic. An autoimmune basis of most of the ′idiopathic′ forms is now hypothesized. Histamine released from mast cells is the major effector in pathogenesis and it is clinically characterized by wheals that have a tendency to recur. Laboratory investigations aimed at a specific etiology are not always conclusive, though may be suggestive of an underlying condition. A clinical search for associated systemic disease is strongly advocated under appropriate circumstances. The mainstay of treatment remains H1 antihistaminics. These may be combined with complementary pharmacopeia in the form of H2 blockers, doxepin, nifedipine and leukotriene inhibitors. More radical therapy in the form of immunoglobulins, plasmapheresis and cyclophosphamide may be required for recalcitrant cases. Autologous transfusion and alternative remedies like acupuncture have prospects for future. A stepwise management results in favorable outcomes. An update on CU based on our experience with patients at a tertiary care centre is presented.

    Science.gov (United States)

    Hõrrak, U.; Salm, J.; Tammet, H.

    1998-06-01

    The mobility spectrum of air ions has been measured at Tahkuse Observatory in Estonia for several years. The average concentration of intermediate ions with mobilities of 0.05-0.5 cm2 V-1 s-1 in atmospheric air is about 50 cm-3. On the level of this low background, high concentration bursts of intermediate air ions occur occasionally. A burst can be followed by subsequent evolution of intermediate ions into larger ones. To explain the bursts of intermediate air ions, two hypotheses can be advanced: (1)A burst of neutral particles occurs due to homogeneous nucleation, and the particles are charged by the attachment of cluster ions. (2) The cluster ions grow by ion-induced nucleation in proper environmental conditions.

  12. Higher order antibunching in intermediate states

    International Nuclear Information System (INIS)

    Since the introduction of binomial state as an intermediate state, different intermediate states have been proposed. Different nonclassical effects have also been reported in these intermediate states. But till now higher order antibunching is predicted in only one type of intermediate state, which is known as shadowed negative binomial state. Recently we have shown that the higher order antibunching is not a rare phenomenon [P. Gupta, P. Pandey, A. Pathak, J. Phys. B 39 (2006) 1137]. To establish our earlier claim further, here we have shown that the higher order antibunching can be seen in different intermediate states, such as binomial state, reciprocal binomial state, hypergeometric state, generalized binomial state, negative binomial state and photon added coherent state. We have studied the possibility of observing the higher order subpoissonian photon statistics in different limits of intermediate states. The effects of different control parameters on the depth of non classicality have also been studied in this connection and it has been shown that the depth of nonclassicality can be tuned by controlling various physical parameters

  15. Partially folded intermediates during trypsinogen denaturation

    Directory of Open Access Journals (Sweden)

    Martins N.F.

    1999-01-01

    Full Text Available The equilibrium unfolding of bovine trypsinogen was studied by circular dichroism, differential spectra and size exclusion HPLC. The change in free energy of denaturation was = 6.99 ± 1.40 kcal/mol for guanidine hydrochloride and = 6.37 ± 0.57 kcal/mol for urea. Satisfactory fits of equilibrium unfolding transitions required a three-state model involving an intermediate in addition to the native and unfolded forms. Size exclusion HPLC allowed the detection of an intermediate population of trypsinogen whose Stokes radii varied from 24.1 ± 0.4 Å to 26.0 ± 0.3 Å for 1.5 M and 2.5 M guanidine hydrochloride, respectively. During urea denaturation, the range of Stokes radii varied from 23.9 ± 0.3 Å to 25.7 ± 0.6 Å for 4.0 M and 6.0 M urea, respectively. Maximal intrinsic fluorescence was observed at about 3.8 M urea with 8-aniline-1-naphthalene sulfonate (ANS binding. These experimental data indicate that the unfolding of bovine trypsinogen is not a simple transition and suggest that the equilibrium intermediate population comprises one intermediate that may be characterized as a molten globule. To obtain further insight by studying intermediates representing different stages of unfolding, we hope to gain a better understanding of the complex interrelations between protein conformation and energetics.

    2016-01-01

    Chronic kidney disease (CKD) is a worldwide public health problem. Patients with CKD have a number of disorders in the organism, and the presence of oxidative stress and systemic inflammation in these patients is the subject of numerous studies. Chronic inflammation joined with oxidative stress contributes to the development of numerous complications: accelerated atherosclerosis process and cardiovascular disease, emergence of Type 2 diabetes mellitus, development of malnutrition, anaemia, hyperparathyroidism, and so forth, affecting the prognosis and quality of life of patients with CKD. In this review we presented the potential role of the myeloperoxidase enzyme in the production of reactive/chlorinating intermediates and their role in oxidative damage to biomolecules in the body of patients with chronic kidney disease and end-stage renal disease. In addition, we discussed the role of modified lipoprotein particles under the influence of prooxidant MPO intermediates in the development of endothelial changes and cardiovascular complications in renal failure.

    Full Text Available Two Prins reactions were investigated by the use of DFT calculations. A model composed of R–CH=CH2 + H3O+(H2O13 + (H2C=O2, R = Me and Ph, was adopted to trace reaction paths. For both alkenes, the concerted path forming 1,3-diols was obtained as the rate determining step (TS1. TS stands for a transition state. From the 1,3-diol, a bimolecular elimination (TS2 leads to the allylic alcohol as the first channel. In the second channel, the 1,3-diol was converted via TS3 into an unprecedented hemiacetal intermediate, HO–CH2–O–CH(R–CH2–CH2–OH. This intermediate undergoes ring closure (TS4, affording the 1,3-dioxane product. The intermediate is of almost the same stability as the product, and two species were suggested to be in a state of equilibrium. While the geometry of TS1 appears to be forwarded to that of a carbocation intermediate, the cation disappeared through the enlargement of the water cluster. Dynamical calculations of a classical trajectory using the atom-centered density matrix propagation molecular dynamics model on the four TSs were carried out, and results of IRC calculations were confirmed by them.

    We study the metric solutions for the gravitational equations in Modified Gravity Models (MGMs). In models with negative powers of the scalar curvature, we show that the Newtonian Limit (NL) is well defined as a limit at intermediate energies, in contrast with the usual low energy interpretation. Indeed, we show that the gravitational interaction is modified at low densities or low curvatures.

    BACKGROUND: Smoking is a major risk factor for lung diseases and lower respiratory symptoms, but since not all smokers develop chronic bronchitis and since chronic bronchitis is also diagnosed in never-smokers, it has been suggested that some individuals are more susceptible to develop chronic...... bronchitis due to genetics. OBJECTIVE: To study the relative influence of genetic and environmental factors on the variation in the susceptibility to chronic bronchitis. METHODS: In a population-based questionnaire study of 13,649 twins, 50-71 years of age, from the Danish Twin Registry, we calculated sex......-specific concordance rates and heritability of chronic bronchitis. The response rate was 75%. RESULTS: The prevalence of chronic bronchitis was 9.3% among men and 8.5% among women. The concordance rate for chronic bronchitis was higher in monozygotic twins than in dizygotic twins among women; 0.30 vs. 0.17, but not...

    2007-01-01

    China's economic development is characterized by progressive integration with international production chains as an assembly producer. Japan and South Korea are the major partners providing intermediate products to China. The present paper analyzes the Chinese intermediate sector's present condition and evolutionary characteristics revealed in bilateral trade with Japan and South Korea. The analysis uses the framework of new trade theory represented by "intra-industry trade". Trade statistics from 1997 to 2004 are analyzed using the database published by the OECD. Results show that China's inter-industrial evolution is characterized by its expanding positioning in the manner of the flying geese development paradigm of Asian countries. Furthermore, intra-industrial evolution is characterized by a concentration on price competitiveness. The framework and results of the industrial analysis presented in this paper assist in the understanding of China's manufacturing evolution and of the policy-making decisions taken in the process.

  2. Comments on intermediate-scale models

    International Nuclear Information System (INIS)

    Some superstring-inspired models employ intermediate scales mI of gauge symmetry breaking. Such scales should exceed 1016 GeV in order to avoid prima facie problems with baryon decay through heavy particles and non-perturbative behaviour of the gauge couplings above mI. However, the intermediate-scale phase transition does not occur until the temperature of the Universe falls below O(mW), after which an enormous excess of entropy is generated. Moreover, gauge symmetry breaking by renormalization group-improved radiative corrections is inapplicable because the symmetry-breaking field has not renormalizable interactions at scales below mI. We also comment on the danger of baryon and lepton number violation in the effective low-energy theory. (orig.)

    2012-02-24

    Intermediate filaments play a key role in cell mechanics. Apart from their great importance from a biomedical point of view, they also act as a very suitable micrometer-sized model system for semiflexible polymers. We perform a statistical analysis of the thermal fluctuations of individual filaments confined in microchannels. The small channel width and the resulting deflections at the walls give rise to a reduction of the configuration space by about 2 orders of magnitude. This circumstance enables us to precisely measure the intrinsic persistence length of vimentin intermediate filaments and to show that they behave as ideal wormlike chains; we observe that small fluctuations in perpendicular planes decouple. Furthermore, the inclusion of results for confined actin filaments demonstrates that the Odijk confinement regime is valid over at least 1 order of magnitude in persistence length. PMID:22463576

  4. Is TW Pictoris really an intermediate polar?

    CERN Document Server

    Norton, A J

    1998-01-01

    We present the results of a long ROSAT HRI observation of the candidate intermediate polar TW Pic. The power spectrum shows no sign of either the previously proposed white dwarf spin period or the proposed binary orbital period (1.996 hr and 6.06 hr respectively). The limits to the X-ray modulation are less than 0.3% in each case. In the absence of a coherent X-ray pulsation, the credentials of TW Pic for membership of the intermediate polar subclass must be suspect. We further suggest that the true orbital period of the binary may be the shorter of the two previously suggested, and that the longer period may represent a quasi-periodic phenomenon associated with the accretion disc.

    A general analytical expression for the double differential cross section of inclusive deuteron stripping reaction on nuclei at intermediate energies of incident particles was obtained in the diffraction approximation. Nucleon-nucleus phases were calculated in the framework of Glauber formalism and making use of the double-folding potential. The exact wave function of deuteron with correct asymptotics at short and long distances between nucleons was used. The calculated angular dependencies of cross sections are in good agreement with corresponding experimental data.

  7. The birthline for intermediate-mass stars

    International Nuclear Information System (INIS)

    The protostar mass-radius relation is combined with standard premain-sequence evolutionary tracks to construct the birthline for stars of intermediate mass. This theoretical birthline is in good agreement with the observed upper envelope of the distribution of Herbig Ae and Be stars in the H-R diagram. From the intersection of the birthline with the ZAMS, it is predicted that stars with more than 10 solar masses should never exhibit an optical premain-sequence phase; this prediction also agrees with existing observations. These findings show that stars of intermediate mass are first optically visible quite close to the main sequence. Hence, their contraction ages are less than the traditional ones derived assuming large initial radii. The birthline is also well delineated by the locus in the diagram of optically visible stars with associated molecular outflows. The underlying protostar theory predicts that newly formed stars of intermediate mass burn deuterium in a subsurface shell. An outer convection zone maintained by this shell burning is proposed to be the cause of the winds and surface activity commonly observed in these stars. 23 refs

  11. Intermediates in Isotopic Exchange Reactions Involving Diborane

    International Nuclear Information System (INIS)

    By conventional mass spectrometric analysis, the self-exchange reaction of diborane was studied by using boron and hydrogen isotopes as tracers. The ratio of deuterium to boron exchange was found to be 2.8. This suggests that the reaction is not completely proceeding by exchange of BH3's as an entity, and that the mechanism is more complicated than simply a stripping reaction between diborane and a borane. It was therefore decided to attempt to get some knowledge of the intermediates that are present in diborane dissociation since they may shed light on the mechanism of the exchange. Using a specially constructed mass spectrometer of high sensitivity coupled with a flow reactor, it was possible to make a direct detection of the intermediate involved in the diborane equilibria. The intermediates BH3 and BH2 were found to be present and their ionization potentials were measured. In addition, a small amount of B3Hn was observed but the value of n could not be determined because of the weak peaks obtained. An attempt is made to interpret the self-exchange reaction of diborane in terms of these intermediates. The results suggest that diborane is in rapid equilibrium with borane (BH3). In addition, apparently diborane can also dissociate in BH2 which was about twice as abundant as BH3. The B3Hn intermediate that was observed is believed to arise from the reaction. BH3 + B2H6 -> B3H9. In applying this information to the isotopic self-exchange in diborane, it appears that the exchange cannot be going by a stripping mechanism such as BD3 + BH3 - BH3 - BD3 - BH3 + BH3, since the deuterium-to-boron isotopic ratio then should be 3. Another possible mechanism of exchange is BD3 + B2H6 ⇌ B3D3H6; the B3 complex can be pictured as a symmetrical one. If the bonds were all exactly equivalent the D/ 10B ratio would statistically become 3; however, some isotope effect may be present in the fragmentation of the complex and the ratio could deviate from 3. Another possible way in which

    Otitis media occurs along a continuum. For example, otitis media with effusion characterized by fluid pathology can lead to chronic otitis media plus chronic mastoiditis, characterized by the presence of intractable tissue pathology such as cholesteatoma, cholesterol granuloma or granulation tissue. The literature defines chronic otitis media as having a tympanic membrane perforation and otorrhea. Amongst many other sequelae, which can result from the continuum, an important common one is chronic silent otitis media. This overlooked entity which includes pathology beneath an intact tympanic membrane is commonly seen in our human temporal bone laboratory and in patients. The clinical pathological correlates of this important disease are discussed herein. PMID:12021496

  16. Intermediate depth seismicity - a reflection seismic approach

    Science.gov (United States)

    Haberland, C.; Rietbrock, A.

    2004-12-01

    During subduction the descending oceanic lithosphere is subject to metamorphic reactions, some of them associated with the release of fluids. It is now widely accepted, that these reactions and associated dehydration processes are directly related with the generation of intermediate depth earthquakes (dehydration embrittlement). However, the structure of the layered oceanic plate at depth and the location of the earthquakes relative to structural units of the subducting plate (sources within the oceanic crust and/or in the upper oceanic mantle lithosphere?) are still not resolved yet. This is in mainly due to the fact that the observational resolution needed to address these topics (in the range of only a few kilometers) is hardly achieved in field experiments and related studies. Here we study the wavefields of intermediate depth earthquakes typically observed by temporary networks in order to assess their high-resolution potential in resolving structure of the down going slab and locus of seismicity. In particular we study whether the subducted oceanic Moho can be detected by the analysis of secondary phases of local earthquakes (near vertical reflection). Due to the irregular geometry of sources and receivers we apply an imaging technique similar to diffraction stack migration. The method is tested using synthetic data both based on 2-D finite difference simulations and 3-D kinematic ray tracing. The accuracy of the hypocenter location and onset times crucial for the successful application of stacking techniques (coherency) was achieved by the use of relatively relocated intermediate depth seismicity. Additionally, we simulate the propagation of the wavefields at larger distance (wide angle) indicating the development of guided waves traveling in the low-velocity waveguide associated with the modeled oceanic crust. We also present application on local earthquake data from the South American subduction zone.

  17. Extrasolar planets around intermediate mass stars

    International Nuclear Information System (INIS)

    One of the earliest hints for extrasolar planets came with the discovery almost 15 years ago of low amplitude, long period radial velocity (RV) variations in several K giant stars, β Gem, α Tau (Aldebaran) and α Boo. Since then it has been confirmed that for β Gem (stellar mass =1.7 Mo-dot) these RV variations are due to a planetary companion. Aldebaran is another K giant star showing long-lived (>26 years) and coherent RV variations. These are most likely due to a planetary companion having a mass of 9 MJup using an estimated mass of 2.5 Mo-dot for the star. Giant stars like α Tau and β Gem offer us the possibility of studying the process of planet formation around stars more massive than the sun. The main sequence stars with masses >1.2 Mo-dot are ill-suited for RV surveys as there are few spectral lines for measuring the RV and these are often broadened by high rates of stellar rotation. Currently over 20 intermediate mass giant stars are known to host extrasolar planets. This sample is sufficiently large that we can begin to look at the overall properties of planets around intermediate mass stars. These suggest that more massive stars may have more massive planets that the orbital eccentricities for their extrasolar planets show the wide range of eccentricities seen for main sequence, solar mass stars, and that unlike for main sequence stars there seems to be no preference for metal rich intermediate mass stars to host extrasolar planets

  18. Intermediate Temperature Solid Oxide Fuel Cell Development

    Energy Technology Data Exchange (ETDEWEB)

    S. Elangovan; Scott Barnett; Sossina Haile

    2008-06-30

    Solid oxide fuel cells (SOFCs) are high efficiency energy conversion devices. Present materials set, using yttria stabilized zirconia (YSZ) electrolyte, limit the cell operating temperatures to 800 C or higher. It has become increasingly evident however that lowering the operating temperature would provide a more expeditious route to commercialization. The advantages of intermediate temperature (600 to 800 C) operation are related to both economic and materials issues. Lower operating temperature allows the use of low cost materials for the balance of plant and limits degradation arising from materials interactions. When the SOFC operating temperature is in the range of 600 to 700 C, it is also possible to partially reform hydrocarbon fuels within the stack providing additional system cost savings by reducing the air preheat heat-exchanger and blower size. The promise of Sr and Mg doped lanthanum gallate (LSGM) electrolyte materials, based on their high ionic conductivity and oxygen transference number at the intermediate temperature is well recognized. The focus of the present project was two-fold: (a) Identify a cell fabrication technique to achieve the benefits of lanthanum gallate material, and (b) Investigate alternative cathode materials that demonstrate low cathode polarization losses at the intermediate temperature. A porous matrix supported, thin film cell configuration was fabricated. The electrode material precursor was infiltrated into the porous matrix and the counter electrode was screen printed. Both anode and cathode infiltration produced high performance cells. Comparison of the two approaches showed that an infiltrated cathode cells may have advantages in high fuel utilization operations. Two new cathode materials were evaluated. Northwestern University investigated LSGM-ceria composite cathode while Caltech evaluated Ba-Sr-Co-Fe (BSCF) based pervoskite cathode. Both cathode materials showed lower polarization losses at temperatures as low as 600

    2014-10-30

    This project aimed to demonstrate increased electronic coupling in silicon nanostructures relative to bulk silicon for the purpose of making high efficiency intermediate bandgap solar cells using silicon. To this end, we formed nanowires with controlled crystallographic orientation, small diameter, <111> sidewall faceting, and passivated surfaces to modify the electronic band structure in silicon by breaking down the symmetry of the crystal lattice. We grew and tested these silicon nanowires with <110>-growth axes, which is an orientation that should produce the coupling enhancement.

    2016-01-01

    In a recent paper [Nuc. Phys. A {\\bf 948}, (2016) 19] we have demonstrated the possible existence of Tsallis' q-Gamow states. Now, accelerators' experimental evidence for Tsallis' distributions has been ascertained only at very high energies. Here, instead, we develop a different set of q-Gamow states for which the associated q-Breit-Wigner distribution could easily be found at intermediate energies, for which accelerators are available at many locations. In this context, it should be strongly emphasized [Physica A {\\bf 388} (2009) 601] that, empirically, one never exactly and unambiguously "detects" pure Gaussians, but rather q-Gaussians. A prediction is made via Eq.(3.30)

    In this paper we build a model of financial intermediation that explains the GDP variability pattern of an economy during the development process. We find evidence that per capita output is more volatile in middle-income economies than in both low and high-income economies. We show that, if the model economy is in the early or in the mature stages of development, there is a unique equilibrium. However, in the middle stages of development, multi-ple equilibria arise. Moreover, we find that in ...

    Barrow, John D; Magueijo, João

    2014-01-01

    We explore the observational implications of models of intermediate inflation driven by modified dispersion relations, specifically those representing the phenomenon of dimensional reduction in the ultraviolet limit. These models are distinct from the standard ones because they do not require violations of the strong energy condition, and this is reflected in their structure formation properties. We find that they can naturally accommodate deviations from exact scale-invariance. They also make clear predictions for the running of the spectral index and tensor modes, rendering the models straightforwardly falsifiable. We discuss the observational prospects for these models and the implications these may have for quantum gravity scenarios.

    1999-07-31

    The longest-running goal of this project has been the synthesis, isolation, and physical chemical characterization of homogeneous transition metal complexes containing ligand types believed to be intermediates in the metal-catalyzed conversion of CO/H{sub 2}, CO{sub 2}, CH{sub 4}, and similar raw materials to organic fuels, feedstocks, etc. In the current project period, complexes that contain unusual new types of C{sub x}(carbide) and C{sub x}O{sub y} (carbon oxide) ligands have been emphasized. A new program in homogeneous fluorous phase catalysis has been launched as described in the final report.

    We examine our previous conjecture that the eta' intermediate resonance has the dominant role in the long distance contributions to B decay into two photons and a strange final state hadron. We calculate the branching ratio of the exclusive B-> K eta'-> K photon photon decay using the nonspectator mechanism for eta' production in charmless hadronic B decays. It is shown that the obtained branching ratio B^eta'(B-> K\\gamma\\gamma)~ 8.7 X 10^{-7} is more than twice as large as the eta_c contribu...

  6. Double photoionization of He at intermediate energies

    International Nuclear Information System (INIS)

    The ratio of double-to-single ionization of He has been measured between 280 and 1210 eV to investigate its behavior in this partially unexplored region. These measurements, compared with the most recent theories of Pan and Kelly (private communication) and of Hino, show the importance of including not only ground state but also final state correlations, in contrast to the high-energy behavior discussed by Dalgarno and Sadeghpour where consideration of final-state correlations proves inessential. The author's intermediate-energy results also appear to indicate the importance of including higher-order effects in the theory

    The S41A mutant of riboflavin synthase from Escherichia coli catalyzes the formation of riboflavin from 6,7-dimethyl-8-ribityllumazine at a very low rate. Quenching of presteady-state reaction mixtures with trifluoroacetic acid afforded a compound with an absorption maximum at 412 nm (pH 1.0) that can be converted to a mixture of riboflavin and 6,7-dimethyl-8-ribityllumazine by treatment with wild-type riboflavin synthase. The compound was shown to qualify as a kinetically competent intermedi...

    2003-01-01

    Full Text Available Organophosphate compound (OPC poisoning with suicidal intent is common in Indian ICUs. The effect of OPCs is to produce a persistent depolarization of the neuromuscular junction leading to muscle weakness. After initial recovery from cholinergic crisis, some patients have resurgence of respiratory muscle paralysis requiring continued ventilatory support. This is termed intermediate syndrome (IMS. This could be due to a change in the type of neuromuscular block to a non depolarisation block characterized by a fade on tetanic stimulation. However peripheral nerve stimulation using train-of-four ratio (TOF and/tetanus have failed to consistently show such a change. We elected to study whether electro physiological monitoring using repetitive nerve stimulation might show a decremental response during IMS. Material & Methods: This was a prospective blinded study done from April 2002 to March 2003 in our ICU. 45 consecutive patients of OPC poisoning admitted during this period were included in this study. Repetitive nerve stimulation (RNS using a train of ten at 3Hz 10Hz and 30Hz (slow , intermediate and fast speeds respectively at the median nerve was done on all patients on day 1, 4, 7 and every 4th day thereafter until discharge. Patients were ventilated until ready to wean as per our usual protocol. The results of the RNS study were not revealed to the intensivist. Results: 9 out of 45 patients required ventilation for more than 6 days and showed overt signs of intermediate syndrome - proximal muscle weakness, twitching and respiratory weakness. Only 2 patients out of the 9 had a decremental response on RNS at 3Hz indicating a post-junctional dysfunction at the motor end-plate, Both patients had consumed a very large quantity of OPC and were deeply comatose for >4 days and required ventilation for >12 days. All other patients with IMS showed no changes on RNS. The exact type of poison consumed varied with each individual patient. Conclusion: RNS

    International Nuclear Information System (INIS)

    Based on the 1984 safety reports the concept of the federal intermediate storage was revised and adapted to meet the new official regulations and guide lines. The most important points such as building architecture and safety, type, quantity and activities with the material being stored, along with in-company flow are described and the resulting radiation exposure to the surroundings and the personnel as well as the costs revealed. Particular emphasis is placed on an improved radiation protection for the operating personnel and the combination of 200 l drums in crates in comparison to individual drum storage. Satisfying result: the above improvements increase the storage capacity keeping additional costs low. 6 figs

    The discovery of the intermediate vector bosons in 1983 at CERN marked the culmination of a long effort to unify the theory of weak and electromagnetic forces. Here a brief outline of development of the electroweak theory which unifies these forces is given first. Its essential feature is the prediction of the existence of the W+- and Z0 bosons with rest masses of about ninety times the proton mass and lifetimes around 10-24s. Then the experimental methods used at CERN to produce and to detect these very massive and short-lived particles are described. (author)

    2006-01-01

    Full Text Available Introduction. The prevalence of chronic diseases in adolescence is constantly increasing, especially in the last two decades. Adolescence is a period of important changes: body growth and development, sexual development, development of cognitive abilities, change in family relations and between peers, formation of personal identity and personal system of values, making decisions on future occupation etc. Chronic diseases in adolescence. Chronic disorders affect all development issues and represent an additional burden for adolescents. The interaction between chronic disorders and various development issues is complex and two-way: the disease may affect development, and development may affect the disease. Developmental, psychosocial and family factors are of great importance in the treatment of adolescents with chronic disorders. Chronic disorders affect all aspects of adolescent life, including relations with peers, school, nutrition, learning, traveling, entertainment, choice of occupation, plans for the future. Physicians should keep in mind that chronic diseases and their treatment represent only one aspect of person's life. Adolescents with chronic diseases have other needs as well, personal priorities, social roles and they expect these needs to be recognized and respected. Adolescent health care should be adjusted to the life style of adolescents.

    2016-01-01

    This article reports on the results of a Fairclough-inspired critical discourse analysis aiming to clarify how chronically ill patients are presented in contemporary Danish chronic care policies. Drawing on Fairclough’s three-dimensional framework for analyzing discourse, and using Dean’s concepts...... of governmentality as an interpretative lens, we analyzed and explained six policies published by the Danish Health and Medicines Authority between 2005 and 2013. The analysis revealed that discourses within the policy vision of chronic care consider chronically ill patients’ active role, lifestyle......, and health behavior to be the main factors influencing susceptibility to chronic diseases. We argue that this discursive construction naturalizes a division between people who can actively manage responsible self-care and those who cannot. Such discourses may serve the interests of those patients who...

    2012-04-10

    We define chronic migraine as that clinical situation in which migraine attacks appear 15 or more days per month. Until recently, and in spite of its negative impact, patients with chronic migraine were excluded of the clinical trials. This manuscript revises the current treatment of chronic migraine. The first step should include the avoidance of potential precipitating/aggravating factors for chronic migraine, mainly analgesic overuse and the treatment of comorbid disorders, such as anxiety and depression. The symptomatic treatment should be based on the use of nonsteroidal anti-inflammatory agents and triptans (in this case ergotamine-containing medications. Preventive treatment includes a 'transitional' treatment with nonsteroidal anti-inflammatory agents or steroids, while preventive treatment exerts its actions. Even though those medications efficacious in episodic migraine prevention are used, the only drugs with demonstrated efficacy in the preventive treatment of chronic migraine are topiramate and pericranial infiltrations of Onabotulinumtoxin A.

    Full Text Available Financial Intermediation, Monetary Uncertainty, and Bank Interest Margins This paper studies a simple model of financial intermediation in order to understand how the lending-borrowing spread or interest margin charged by financial intermediaries is determined in equilibrium in a monetary economy. The main conclusion of the paper concerns the effect on the spread of changes in the distribution of monetary innovations. Thus, changes in the monetary-policy-rule followed by the Central Bank which alter the volatility of inflation will have important effects on the interest margin and also on the amount of credit available to investors. A crosssection empirical analysis strongly supports our hypothesis:

  4. Reactivity of surface carbonaceous intermediates. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Koerts, T.

    1992-06-19

    The study has concentrated on two reactions both related with carbon-carbon bond formation on transition metal catalysts. The first concerns the influences of a vanadium promoter on the kinetics of elementary reaction steps upon synthesis gas conversion on a rhodium catalyst. The second is related to the general problem of initiating a carbon-carbon bond between two methane molecules. Both reactions occur via reactive C1 surface intermediates. These surface species were created from CO and CH4 respectively. Mainly transient kinetic techniques were used which were combined with some quantum chemical calculations. The influence of a vanadium promoter on the formation and intrinsic reactivity of CHx species adsorbed on rhodium catalysts, for hydrogenation, chaingrowth and CO insertion, has also been investigated. On rhodium catalysts a very reactive C1 intermediate was found to be formed from dissociative CO adsorption. The formation of the surface species was found to be enhanced by vanadium promotion, which lowers the activation energy for CO dissociation.

    Full Text Available The financial intermediation of bank institutions, has an essential role in mobilising of the available funds and their distribution in various products and services, for economic growth. The extent that banking system is in distress or passing through a period of crisis, then, everything turns into a general crisis, especially that, in some states, natural and legal persons have been learned ,,to live’’ on the credits.The effectiveness of banking intermediation activity in Romania depends on how fast the market is enabled under the influence of the new European regulations. The Romanian market in all its forms is the second largest in the EU, and the banking system is almost entirely made up of banks with foreign capital. The romanian banking market has not suffered so much because of the financial crisis. To the extent that banking institutions provide the necessary funds, Romania has important resources for the transition to a new economic cycle based on sustainable development.

  6. Neutron scattering on intermediate valence systems

    International Nuclear Information System (INIS)

    The temperature dependence of the magnetic relaxation line widths (quasielastic (QE) line widths) and the crystal field excitations of some novel intermediate valent systems were measured by means of inelastic neutron scattering. Some striking new features of the alloys YbBe13, YbPd and Yb3Pd4 appoint them to belong to a new type of intermediate valent systems. YbAl3 shows several inelastic lines, but no QE-line was measurable. The heavy fermion systems CeCu6 and URu2Si2 show a strongly temperature dependent QE-line width, in course of which CeCu6 tends towards a nonvanishing residual value for T->0, which matches with theoretical predictions. For the first time valence instabilities of Pr (PrPd) and Sm (Smsub(0.51)Ysub(0.49)Al2) could be prooved by neutron scattering. In addition to these experiments, in YbCu2Si2 and TmTe the shifts in valency, caused by external hydrostatic pressure, were studied with a pressure cell for neutron scattering, especially designed and constructed for these special purposes. The corresponding observed changes of the QE-line widths coincide with the expected values, both in sign and absolute value. (orig.)

  7. Intermediate-field transport of contaminants

    International Nuclear Information System (INIS)

    This report is about ''intermediate-field'' transport or the migration of contaminants from arrays of discrete waste packages or sources. In constructing nuclear waste repositories in rock, it may be necessary to place a waste package across a rock fracture, or a rock fracture may develop some time after waste packages have been emplaced. To predict the spatial and temporal distribution of contaminant species from a line of waste packages facing a rock fracture may be important, because such fractures may now be considered a preferential pathway for released radionuclides to re-enter the biosphere. In land disposal of hazardous wastes, individual barrels may contain especially toxic material whose dispersion special attention. We have published analytic solutions for the multidimensional advective transport of contaminants from arrays of waste packages and multiple areal sources into a planar fracture. The results show a near region in which the concentrations vary greatly in the direction transverse to ground-water flow, an intermediate region in which the array can be treated as an infinite plane source of dissolving species, and a far-field region in which the array can be treated as a plane source of finite extent. The array equations have been developed for both porous and fractured media. In this paper we summarize and compare the work with multiple areal sources facing a planar fracture and an array of point sources in porous media. 5 refs., 5 figs

  8. Fluorescence and bioluminescence of bacterial luciferase intermediates

    International Nuclear Information System (INIS)

    An intermediate in the luciferase-catalyzed bioluminescent oxidation of FMNH2, isolated and purified by chromatography at --200, was postulated to be an oxygenated reduced flavine-luciferase. Maintained and studied at --20 to --300, this material exhibits a relatively weak fluorescence emission peaking at about 505 nm when excited at 370 nm. It may comprise more than one species. Upon continued exposure to light at 370 nm, the intensity of this fluorescence increases, often by a factor of 5 or more, and its emission spectrum is blue shifted to a maximum at about 485 nm. Upon warming this fluorescence is lost and the fluorescence of flavine mononucleotide appears. If warming is carried out in the presence of a long chain aldehyde, bioluminescence occurs, with the appearance of a similar amount of flavine fluorescence. The bioluminescence yield is about the same with irradiated and nonirradiated samples. The bioluminescence emission spectrum corresponds exactly to the fluorescence emission spectrum of the intermediate formed by irradiation, implicating the latter as being structurally close to the emitting species in bioluminescence.

  9. Intermediate energy nuclear data: models and codes

    International Nuclear Information System (INIS)

    This specialists' meeting was organised as a follow-up to the recent report by the NEA Nuclear Science Committee entitled International Code Comparison for Intermediate Energy Nuclear Data, which addresses the subject the of codes and models used to calculate nuclear reaction processes from 20 to 1600 MeV. This effort is part of the programme of work of the Agency in the area of partitioning and transmutation of radioactive waste from the nuclear industry. Two benchmark exercises had been organised by the NEA. The results of the first one on microscopic nuclear reaction calculations (thin target) were published prior to the meeting. The second exercise, on transport calculations (thick target), is still in progress. The objective of the study is to help determine the predictive capacity of current nuclear reaction and transport codes for future design concepts for transmutation as well as for other application areas, such as radiation oncology, accelerator shielding, astrophysics, radiation during space travel, etc. The purpose of the meeting was to bring together the participants in the intercomparison exercises to: (a) discuss the relative merits and deficiencies encountered in the use of various codes and models throughout the world, (b) issue recommendations for future developments in codes and identify intermediate energy data needs, both experimental and evaluated

  10. Intermediate mass Higgs boson(s)

    International Nuclear Information System (INIS)

    Finding and understanding the spectrum of scalar bosons is the central problem of particle physics today. Considerable work has been done to learn how to study Standard Model heavy and obese Higgs bosons; simulations including the problems induced by standard model backgrounds are underway, and some results are reported elsewhere in these proceedings. The mass region MH Z/2 will be covered at SLC and LEP. LEPII will be able to extend this range to about 85 GeV. Above MH > 2MZ the search is easy for a Standard Model H degree at the SSC, though not so simple for the neutral scalars of a supersymmetric theory. The intermediate region, MZ/2 ≤ MH ≤ 2MZ is one of the most difficult mass regions to study, and it is the subject of this report. The authors concentrate on a neutral Standard Model scalar to be specific. The lightest scalar of a supersymmetric theory behaves very much like a Standard Model scalar for most ranges of parameters, so the results generally apply to that case as well, and for any form the scalar spectrum might take our results indicate how the analysis might go. Ultimately, to fully understand spontaneous symmetry breaking and the origin of mass, it will be necessary to find any intermediate mass scalar and to know in what mass ranges no scalars exist. Their analysis is only in progress, and their results reported here must be regarded as tentative

    Intermediate care is an important focus of the Taiwan Government, domestic diagnosis groups, and the Ten-Year Long-Term Care Project. The objective of intermediate care is to bridge acute and long-term care in order to deliver more comprehensive healthcare to the population. It is an emerging healthcare service model. Intermediate care and a supportive environment should facilitate the functional recovery of patients and their successful return to the community. This article first describes the origins of intermediate care, its definitions and components, service models and related research. It then proposes the role of nursing in intermediate care and implications for nursing in the future of domestic intermediate care policy. We hope that academia, the government and health industry can work together to facilitate intermediate care in order to extend and expand nursing roles. PMID:21678256

    We extend our previous stochastic cellular automata based model for areal aggregation of prion proteins on neuronal surfaces. The new anisotropic model allow us to simulate both strong beta-sheet and weaker attachment bonds between proteins. Constraining binding directions allows us to generate aggregate structures with the hexagonal lattice symmetry found in recently observed in vitro experiments. We argue that these constraints on rules may correspond to underlying steric constraints on the aggregation process. We find that monomer dominated growth of the areal aggregate is too slow to account for some observed doubling time-to-incubation time ratios inferred from data, and so consider aggregation dominated by relatively stable but non-infectious oligomeric intermediates. We compare a kinetic theory analysis of oligomeric aggregation to spatially explicit simulations of the process. We find that with suitable rules for misfolding of oligomers, possibly due to water exclusion by the surrounding aggregate, th...

    2013-08-15

    This report presents a feasibility study of a melting facility for core components and reactor internals. An overview is given of how such a facility for treatment of intermediate level waste might be designed, constructed and operated and highlights both the possibilities and challenges. A cost estimate and a risk analysis are presented in order to make a conclusion of the technical feasibility of such a facility. Based on the authors' experience in operating a low level waste melting facility, their conclusion is that without technical improvements such a facility is not feasible today. This is based on the cost of constructing and operating such a facility, in conjunction with the radiological risks associated with operation and the uncertain benefits to disposal and long term safety.

  17. Analysis of Intermediate Energy Photonuclear Reactions

    International Nuclear Information System (INIS)

    The Cascade-Exciton Model (CEM) of nuclear reactions has been extended to describe photonuclear disintegration at intermediate energies. Using the CEM and the ORNL version of the Intranuclear Cascade Model for incident energies higher than the giant dipole resonance (GDR) region, and a group theory formalism based on the Interacting Boson Model in the GDR region, we have analyzed a variety of data for reactions induced by photons with energies up to ∼ 1.2 GeV and target-nuclei from 12C to 243Am. The contributions of different photon absorption mechanisms and the relative role of different particle production mechanisms in these reactions are discussed. 41 refs., 7 figs., 1 tab

    Picking out a DBI scalar field as inflation, the slow-rolling inflationary scenario is studied by attributing an exponential time function to scale factor, known as intermediate inflation. The perturbation parameters of the model are estimated numerically for two different cases, and the final result is compared with Planck data. The diagram of tensor-to-scalar ratio r versus scalar spectra index ns is illustrated, and it is found that they are within an acceptable range as suggested by Planck. In addition, the acquired values for amplitude of scalar perturbation reveal the ability of the model to depict a good picture of the Universe in one of its earliest stages. As a further argument, the non-Gaussianity is investigated, displaying that the model prediction stands in a 68% C.L. regime according to the latest Planck data.

    2013-04-01

    The STAR experiment at the Relative Heavy Ion Collider in Brookhaven National Laboratory at Upton, NY will soon be upgraded with the a Heavy Flavor Tracker (HFT), which will greatly enhance the capability for heavy flavor studies by measurements of displaced vertices and direct topological reconstruction of open charm hadrons. The HFT consists of 4 layers of silicon detectors. The Intermediate Silicon Tracker (IST) is one of these layers. It uses conventional silicon pad sensors, which provide a position resolution of about 180 (1800) microns in the r-phi (longitudinal) direction. The IST detector is in production now so that it will be ready for installation in Fall 2013. In this talk, we will present the design and performance of the IST, and the status of the production.

    2015-01-01

    Full Text Available The 2007 World Health Organization classification of tumors of the central nervous system identified "pineal parenchymal tumor of intermediate differentiation" (PPTID as a new pineal parenchymal neoplasm, located between pineocytoma and pineoblastoma as grade II or III. Because of the small number of reported cases, the classification of PPT is still a matter of controversy. We report a case of PPTID. A 25-year-old female patient was admitted to hospital with complaints of a headache, nausea, vomiting since 1-year. Computed tomography/magnetic resonance imaging of the brain showed well-defined, mildly enhancing lesion in the region of the pineal gland with areas of calcification. The tumor was excised. After 3 years, she presented with metastasis in thoracic and lumbosacral spinal region. This is a rare event.

  1. Environmental issues of an intermediate city

    International Nuclear Information System (INIS)

    Our urban centers present a unique dimension of environmental problems. They are at one and the same time, enormous consumers of natural resources and produces of waste and pollution. In this respect intermediate cities and small towns appear to be more vulnerable to natural catastrophes and ecological accidents caused by human factors. While in large cities there exist pressure groups which attain government attention for the solution of their problems and have well equipped municipalities. However, a vast majority of the population lives in rural areas and depends upon medium sized cities and towns for access to services. These cities and towns form the pivot of economic, social, cultural and political life for a large part of the population. Therefore, it deserves more attention than bigger ones. This paper explores local people perception about urban environmental problems exist in the city. Attempts are also made to shape and guide municipality efforts to overcome such problems with available resources. (author)

  2. Kinetic advantage of controlled intermediate nuclear fusion

    Science.gov (United States)

    Guo, Xiaoming

    2012-09-01

    The dominated process of controlled fusion is to let nuclei gain enough kinetic energy to overcome Coulomb barrier. As a result, a fusion scheme can consider two factors in its design: to increase kinetic energy of nuclei and to alter the Coulomb barrier. Cold Fusion and Hot fusion are all one-factor schemes while Intermediate Fusion is a twofactors scheme. This made CINF kinetically superior. Cold Fusion reduces deuteron-deuteron distance, addressing Coulomb barrier, and Hot Fusion heat up plasma into extreme high temperature, addressing kinetic energy. Without enough kinetic energy made Cold Fusion skeptical. Extreme high temperature made Hot Fusion very difficult to engineer. Because CIFN addresses both factors, CIFN is a more promising technique to be industrialized.

    A 4 light charged particle spectrometer, called 8 LP, is in operation at the Laboratori Nazionali di Legnaro, Italy, for studying reaction mechanisms in low-energy heavy-ion reactions. Besides about 300 telescopes to detect light charged particles, the spectrometer is also equipped with an anular PPAC system to detect evaporation residues and a two-arm time-of-flight spectrometer to detect fission fragments. The spectrometer has been used in several fission dynamics studies using as a probe light charged particles in the fission and evaporation residues (ER) channels. This paper proposes a journey within some open questions about the fission dynamics and a review of the main results concerning nuclear dissipation and fission time-scale obtained from several of these studies. In particular, the advantages of using systems of intermediate fissility will be discussed.

    Credible climate predictions require a rational quantification of uncertainty, but full Bayesian calibration requires detailed estimates of prior probability distributions and covariances, which are difficult to obtain in practice. We describe a simplified procedure, termed precalibration, which provides an approximate quantification of uncertainty in climate prediction, and requires only that uncontroversially implausible values of certain inputs and outputs are identified. The method is applied to intermediate-complexity model simulations of the Atlantic meridional overturning circulation (AMOC) and confirms the existence of a cliff-edge catastrophe in freshwater-forcing input space. When uncertainty in 14 further parameters is taken into account, an implausible, AMOC-off, region remains as a robust feature of the model dynamics, but its location is found to depend strongly on values of the other parameters.

  5. Thermal hydraulic design of intermediate heat exchanger

    International Nuclear Information System (INIS)

    Intermediate heat exchanger (IHX) is a very important component of Fast Breeder Reactor because it forms the boundary between radioactive primary sodium and non-radioactive secondary sodium. IHX of the 500 MWe Prototype Fast Breeder Reactor is a shell and tube heat exchanger with primary sodium flowing on the shell side. Cross flow heat transfer at the primary sodium entrance demands unequal secondary flow distribution in various tubes to ensure good safety margin in structural design. This paper brings out details of thermal hydraulic studies to arrive at a suitable secondary flow distribution and choice of a suitable flow distribution device to achieve the same. Application of two-dimensional analysis with computer code THYC-2D has been brought out. (author). 5 refs., 14 figs., 2 tabs

  7. Connectomic intermediate phenotypes for psychiatric disorders

    Full Text Available Psychiatric disorders are phenotypically heterogeneous entities with a complex genetic basis. To mitigate this complexity, many investigators study so-called intermediate phenotypes that putatively provide a more direct index of the physiological effects of candidate genetic risk variants than overt psychiatric syndromes. Magnetic resonance imaging (MRI is a particularly popular technique for measuring such phenotypes because it allows interrogation of diverse aspects of brain structure and function in vivo. Much of this work however, has focused on relatively simple measures that quantify variations in the physiology or tissue integrity of specific brain regions in isolation, contradicting an emerging consensus that most major psychiatric disorders do not arise from isolated dysfunction in one or a few brain regions, but rather from disturbed interactions within and between distributed neural circuits; i.e., they are disorders of brain connectivity. The recent proliferation of new MRI techniques for comprehensively mapping the entire connectivity architecture of the brain, termed the human connectome, has provided a rich repertoire of tools for understanding how genetic variants implicated in mental disorder impact distinct neural circuits. In this article, we review research using these connectomic techniques to understand how genetic variation influences the connectivity and topology of human brain networks. We highlight recent evidence from twin and imaging genetics studies suggesting that the penetrance of candidate risk variants for mental illness, such as those in SLC6A4, MAOA, ZNF804A and APOE, may be higher for intermediate phenotypes characterised at the level of distributed neural systems than at the level of spatially localised brain regions. The findings indicate that imaging connectomics provides a powerful framework for understanding how genetic risk for psychiatric disease is expressed through altered structure and function of

    2012-02-01

    In the summer of 2007, the U.S. Department of Energy (DOE) initiated a test program to evaluate the potential impacts of intermediate ethanol blends (also known as mid-level blends) on legacy vehicles and other engines. The purpose of the test program was to develop information important to assessing the viability of using intermediate blends as a contributor to meeting national goals for the use of renewable fuels. Through a wide range of experimental activities, DOE is evaluating the effects of E15 and E20 - gasoline blended with 15% and 20% ethanol - on tailpipe and evaporative emissions, catalyst and engine durability, vehicle driveability, engine operability, and vehicle and engine materials. This report provides the results of the catalyst durability study, a substantial part of the overall test program. Results from additional projects will be reported separately. The principal purpose of the catalyst durability study was to investigate the effects of adding up to 20% ethanol to gasoline on the durability of catalysts and other aspects of the emissions control systems of vehicles. Section 1 provides further information about the purpose and context of the study. Section 2 describes the experimental approach for the test program, including vehicle selection, aging and emissions test cycle, fuel selection, and data handling and analysis. Section 3 summarizes the effects of the ethanol blends on emissions and fuel economy of the test vehicles. Section 4 summarizes notable unscheduled maintenance and testing issues experienced during the program. The appendixes provide additional detail about the statistical models used in the analysis, detailed statistical analyses, and detailed vehicle specifications.

    Full Text Available Context :Alcohol is the major aetiological agent for both chronic pancreatitis and alcoholic liver disease. However, as only a minority of alcoholics develop either chronic pancreatitis or alcoholic liver disease, there are clearly genetic or environmental cofactors that determine individual susceptibility to these diseases. Objective: To determine whether polymorphisms of the TNF gene may account for individual susceptibility to develop chronic pancreatitis or alcoholic liver disease. Design: A controlled study. Patients: We analyzed 73 patients with chronic pancreatitis, 103 healthy controls, 39 patients with alcoholic liver disease and 29 alcoholics without liver or pancreatic disease. Results: The intermediate/low TNF secreting haplotype a6b5c1d3e3 was over-represented in chronic pancreatitis compared to healthy controls (OR=2.08; 95% CI: 1.07-4.06; P=0.019 and in alcoholic chronic pancreatitis compared to healthy controls (OR=2.08; 95% CI: 1.01-4.29; P=0.029. The high TNF secreting haplotypes, a2b3c1d1e3 and a2b5c2d4e3 were under-represented in chronic pancreatitis compared to healthy controls (OR=0.48; 95% CI: 0.22-1.04; P= 0.043 and in alcoholic chronic pancreatitis compared to alcoholic controls (OR=0.20; 95% CI: 0.05-0.77; P=0.014, respectively. Conclusion :A reduced capacity to produce TNF may be responsible for the induction of chronic pancreatitis.

    2015-12-01

    There are a variety of medical conditions associated with chronic sinonasal inflammation, including chronic rhinosinusitis (CRS) and cystic fibrosis. In particular, CRS can be divided into 2 major subgroups based on whether nasal polyps are present or absent. Unfortunately, clinical treatment strategies for patients with chronic sinonasal inflammation are limited, in part because the underlying mechanisms contributing to disease pathology are heterogeneous and not entirely known. It is hypothesized that alterations in mucociliary clearance, abnormalities in the sinonasal epithelial cell barrier, and tissue remodeling all contribute to the chronic inflammatory and tissue-deforming processes characteristic of CRS. Additionally, the host innate and adaptive immune responses are also significantly activated and might be involved in pathogenesis. Recent advancements in the understanding of CRS pathogenesis are highlighted in this review, with special focus placed on the roles of epithelial cells and the host immune response in patients with cystic fibrosis, CRS without nasal polyps, or CRS with nasal polyps.

    2003-01-01

    Full Text Available Chronic penile strangulation is exceedingly rare with only 5 cases previously reported. We report an additional case of progressive penile lymphedema due to chronic intermittent strangulation caused by a rubber band applied to the penile base for 6 years. A 49-year-old man presented incapacity to exteriorize the glans penis. For erotic purposes, he had been using a rubber-enlarging band placed in the penile base for 6 years. With chronic use, he noticed that his penis swelled. Physical examination revealed lymphedema of the penis, phimosis and a stricture in the penile base. The patient was submitted to circumcision and the lymphedema remained stable 10 months postoperatively. Chronic penile incarceration usually causes penile lymphedema and urinary disturbance. Treatment consists of removal of foreign devices and surgical treatment of lymphedema.

    Directory of Open Access Journals (Sweden)

    Khadilkar Satish

    2011-01-01

    Full Text Available The spectrum of chronic dysimmune neuropathies has widened well beyond chronic demyelinating polyradiculoneuropathy (CIDP. Pure motor (multifocal motor neuropathy, sensorimotor with asymmetrical involvement (multifocal acquired demylinating sensory and motor neuropathy, exclusively distal sensory (distal acquired demyelinating sensory neuropathy and very proximal sensory (chronic immune sensory polyradiculopathy constitute the variants of CIDP. Correct diagnosis of these entities is of importance in terms of initiation of appropriate therapy as well as prognostication of these patients. The rates of detection of immune-mediated neuropathies with monoclonal cell proliferation (monoclonal gammopathy of unknown significance, multiple myeloma, etc. have been facilitated as better diagnostic tools such as serum immunofixation electrophoresis are being used more often. Immune neuropathies associated with malignancies and systemic vasculitic disorders are being defined further and treated early with better understanding of the disease processes. As this field of dysimmune neuropathies will evolve in the future, some of the curious aspects of the clinical presentations and response patterns to different immunosuppressants or immunomodulators will be further elucidated. This review also discusses representative case studies.

    There is increasing interest in the use of complimentary and alternative medicine (CAM) for the treatment of chronic pain. This review examines alternative and complimentary therapies, which can be incorporated as part of a biopsychosocial approach in the treatment of chronic pain syndromes. In the present investigation, literature from articles indexed on PubMed was evaluated including topics of alternative therapies, complimentary therapies, pain psychology, biofeedback therapy, physical exercise therapies, acupuncture, natural and herbal supplements, whole-body cryotherapy, and smartphone technologies in the treatment of chronic pain syndromes. This review highlights the key role of psychology in the treatment of chronic pain. Cognitive behavior therapy appears to be the most impactful while biofeedback therapy has also been shown to be effective for chronic pain. Exercise therapy has been shown to be effective in short-, intermediate-, and long-term pain states. When compared to that in sham controls, acupuncture has shown some benefit for neck pain immediately after the procedure and in the short term and improvement has also been demonstrated in the treatment of headaches. The role of smartphones and whole-body cryotherapy are new modalities and further studies are needed. Recent literature suggests that several alternate therapies could play a role in the treatment of chronic pain, supporting the biopsychosocial model in the treatment of pain states. PMID:27038968

The clinical, radiological, and histological appearances of this case will be discussed.

  12. Hypertension in Chronic Glomerulonephritis.

    Ihm, Chun-Gyoo

    2015-12-01

    Chronic glomerulonephritis (GN), which includes focal segmental glomerulosclerosis and proliferative forms of GN such as IgA nephropathy, increases the risk of hypertension. Hypertension in chronic GN is primarily volume dependent, and this increase in blood volume is not related to the deterioration of renal function. Patients with chronic GN become salt sensitive as renal damage including arteriolosclerosis progresses and the consequent renal ischemia causes the stimulation of the intrarenal renin-angiotensin-aldosterone system(RAAS). Overactivity of the sympathetic nervous system also contributes to hypertension in chronic GN. According to the KDIGO guideline, the available evidence indicates that the target BP should be ≤140mmHg systolic and ≤90mmHg diastolic in chronic kidney disease patients without albuminuria. In most patients with an albumin excretion rate of ≥30mg/24 h (i.e., those with both micro-and macroalbuminuria), a lower target of ≤130mmHg systolic and ≤80mmHg diastolic is suggested. The use of agents that block the RAAS system is recommended or suggested in all patients with an albumin excretion rate of ≥30mg/ 24 h. The combination of a RAAS blockade with a calcium channel blocker and a diuretic may be effective in attaining the target BP, and in reducing the amount of urinary protein excretion in patients with chronic GN.

    Objective To investigate the protective effects of astragalosides IV (As-IV)on high insulin induced human mesangial cells (HMCs)injury in vitro and its mechanisms.Methods We used HMCs as research object, treated HMCs with different concentrations and time of insulin,analyzed the proliferation by MTT assay to select the dose-and time-dependent manners of insulin.The HMCs was divided and treated as follows:normal group (NG), high insulin group (HINS,64 nmol /L),DPI (10 μmol /L),Tempol (100 μmol /L),LY294002 (10 μmol /L) and As-IV (25,50,100 μmol /L).After treatment for 48 hours,the proliferation of HMCs was analyzed by MTT assay.The reactive oxygen species (ROS)production was measured by 2,7-dichlorodihydto fluorescin diacetate (DCFH-DA).The expressions of NADPH oxidase 4 (NOX4),phosphor-protein kinase b (p-PKB)also named p-Akt and phosphor-mammalian target of rapamycin (p-mTOR)were analyzed by Western blot.Results The prolif-eration of HMCs was enhanced in a dose-and time-dependent manner by increasing concentrations and time of insu-lin.Compared with HINS group,DPI,Tempol,LY294002,As-IV treatment significantly inhibited HMCs prolifer-ation,reduced intracellular ROS contents and decreased expression of NOX4,p-Akt and p-mTOR (P <0.05,P <0.01).Conclusion Insulin promotes proliferation of HMCs in a time-and dose-dependent manner.As-IV has protective effects on high insulin induced HMCs injury due to inhibition of HMCs proliferation,oxidative damage, NOX4,p-Akt and p-mTOR expression.%目的:研究黄芪甲苷(As-IV)对高胰岛素诱导人肾小球系膜细胞(HMCs)损伤的保护作用及其机制。方法以HMCs 为研究对象,用 MTT 法检测不同浓度胰岛素作用不同时间后对 HMCs 增殖的影响,筛选胰岛素的量效与时效关系;实验设正常组、高胰岛素(64 nmol/L)组、二碘苯(DPI 10μmol/L)组、抗氧化剂 Tempol(100μmol/L)组、PI3K/Akt 信号通路抑制剂 LY294002(10μmol/L

  14. Nucleon-induced fission at intermediate energies

    International Nuclear Information System (INIS)

    The absence of a satisfactory theoretical description to predict isotope yields as well as the need for experimental fragment mass and charge distributions at intermediate-energies form the motivation of this work. Like the objects under study, the research presented in this thesis consists two main parts. Part 1 concerns an activation experiment that has been performed at the 'Kernfysisch Versneller Instituut' (Nuclear Physics Accelerator Institute) in Groningen, Netherlands, using the AGOR cyclotron. Fission product yields have been measured resulting from 190 MeV proton-induced fission of natW, 197Au, natPb, 208Pb and 232Th. In Chapter 2 the experimental set up is discussed, followed in Chapter 3 by a description of the data analysis. The results on the reconstructed mass yields and the total fission cross sections are presented in Chapter 4. Part 2 is of a theoretical nature. The objective is to compute fission product mass yields from intermediate-energy nucleon-induced reactions. In the approach presented here, two stages can be distinguished. In the first stage the fission cross section is determined for the various fissioning isotopes as a function of their excitation energy in competition with other processes like pre-equilibrium decay and particle evaporation. ALICE-91 is a nuclear reaction code that takes care of this first stage. The second stage consists of constructing the total fission-fragment mass and charge distributions from the different contributions of all the equilibrated fissioning systems. Hence, a model is needed that gives a prediction for the fission-product mass yields in a large range of mass, charge, and excitation energy of the fissioning nucleus. For this purpose, the multi-modal random neck-rupture model by Brosa is extended with temperature-dependent shell and pairing corrections and a temperature-dependent LDM. The combination of ALICE-91 and the modified Brosa approach is used for the analysis of the experiments given in the

    We develop tests of financial intermediation by national banking systems based on the expectation that, in commercial systems, financial intermediation should not be overly influenced by policy variables; should be greater in richer, faster growing industrial areas; and should direct funds to the best projects regardless of where deposits originate. Using Chinese provincial data from 1991 to 1997, we test whether financial reforms in the mid-1990s increased efficient intermediation by differe...

    Until recently, the economics and financial literature placed little attention on the role that financial intermediation can play in accelerating the rate of economic development in less Developed Countries (LDCs). This has been changed now, however, where some instrumental role has been emphasised for financial intermediation in the process of economic development and growth. It is argued that an expansion of the financial system, size and intermediation in LDCs tends to increase the level o...

    Between the robust but slow (primal or dual) gradient methods and the fast but sensitive to errors fast gradient methods, our goal in this paper is to develop first-order methods for smooth convex problems with intermediate speed and intermediate sensitivity to errors. We develop a general family of first-order methods, the Intermediate Gradient Method (IGM), based on two sequences of coefficients. We prove that the behavior of such kind of method is directly governed by the choice of coeffic...

  2. Three-body scattering at intermediate energies

    International Nuclear Information System (INIS)

    The Faddeev equation for three-body scattering at arbitrary energies is formulated in momentum space and directly solved in terms of momentum vectors without employing a partial-wave decomposition. In its simplest form, the Faddeev equation for identical bosons, which we are using, is a three-dimensional integral equation in five variables, magnitudes of relative momenta and angles. This equation is solved through Pade summation. Based on a Malfliet-Tjon-type potential, the numerical feasibility and stability of the algorithm for solving the Faddeev equation is demonstrated. Special attention is given to the selection of independent variables and the treatment of three-body breakup singularities with a spline-based method. The elastic differential cross section, semiexclusive d(N,N') cross sections, and total cross sections of both elastic and breakup processes in the intermediate-energy range up to about 1 GeV are calculated and the convergence of the multiple-scattering series is investigated in every case. In general, a truncation in the first or second order in the two-body t matrix is quite insufficient

    In cuprate superconductors, adjacent cuprate double-planes are intrinsically Josephson-coupled. For bias currents perpendicular to the planes, the current-voltage characteristics correspond to those of an array of underdamped Josephson junctions. We will discuss our experiments on sub-micron Tl-2212 intrinsic Josephson junctions (IJJs). The dynamics of the IJJs at the plasma frequency are moderately damped (Q ~ 8). This results in a number of counter-intuitive observations, including both a suppression of the effect of thermal fluctuations and a shift of the skewness of the switching current distributions from negative to positive as the temperature is increased. Simulations confirm that these phenomena result from repeated phase slips as the IJJ switches from the zero-voltage to the running state. We further show that increased dissipation counter-intuitively increases the maximum supercurrent in the intermediate damping regime (PRL vol. 103, art. no. 217002). We discuss the role of environmental dissipation on the dynamics and describe experiments with on-chip lumped-element passive components in order control the environment seen by the IJJs.

    1998-12-01

    We have cloned cytoplasmic intermediate filament (IF) proteins from a large number of invertebrate phyla using cDNA probes, the monoclonal antibody IFA, peptide sequence information, and various RT-PCR procedures. Novel IF protein sequences reported here include the urochordata and nine protostomic phyla, i.e., Annelida, Brachiopoda, Chaetognatha, Echiura, Nematomorpha, Nemertea, Platyhelminthes, Phoronida, and Sipuncula. Taken together with the wealth of data on IF proteins of vertebrates and the results on IF proteins of Cephalochordata, Mollusca, Annelida, and Nematoda, two IF prototypes emerge. The L-type, which includes 35 sequences from 11 protostomic phyla, shares with the nuclear lamins the long version of the coil 1b subdomain and, in most cases, a homology segment of some 120 residues in the carboxyterminal tail domain. The S-type, which includes all four subfamilies (types I to IV) of vertebrate IF proteins, lacks 42 residues in the coil 1b subdomain and the carboxyterminal lamin homology segment. Since IF proteins from all three phyla of the chordates have the 42-residue deletion, this deletion arose in a progenitor prior to the divergence of the chordates into the urochordate, cephalochordate, and vertebrate lineages, possibly already at the origin of the deuterostomic branch. Four phyla recently placed into the protostomia on grounds of their 18S rDNA sequences (Brachiopoda, Nemertea, Phoronida, and Platyhelminthes) show IF proteins of the L-type and fit by sequence identity criteria into the lophotrochozoic branch of the protostomia.

    2008-10-01

    Full Text Available Abstract Reactive oxygen species (ROS generated within cells or, more generally, in a tissue environment, may easily turn into a source of cell and tissue injury. Aerobic organisms have developed evolutionarily conserved mechanisms and strategies to carefully control the generation of ROS and other oxidative stress-related radical or non-radical reactive intermediates (that is, to maintain redox homeostasis, as well as to 'make use' of these molecules under physiological conditions as tools to modulate signal transduction, gene expression and cellular functional responses (that is, redox signalling. However, a derangement in redox homeostasis, resulting in sustained levels of oxidative stress and related mediators, can play a significant role in the pathogenesis of major human diseases characterized by chronic inflammation, chronic activation of wound healing and tissue fibrogenesis. This review has been designed to first offer a critical introduction to current knowledge in the field of redox research in order to introduce readers to the complexity of redox signalling and redox homeostasis. This will include ready-to-use key information and concepts on ROS, free radicals and oxidative stress-related reactive intermediates and reactions, sources of ROS in mammalian cells and tissues, antioxidant defences, redox sensors and, more generally, the major principles of redox signalling and redox-dependent transcriptional regulation of mammalian cells. This information will serve as a basis of knowledge to introduce the role of ROS and other oxidative stress-related intermediates in contributing to essential events, such as the induction of cell death, the perpetuation of chronic inflammatory responses, fibrogenesis and much more, with a major focus on hepatic chronic wound healing and liver fibrogenesis.

    Full Text Available Chronic Daily Headache is a descriptive term that includes disorders with headaches on more days than not and affects 4% of the general population. The condition has a debilitating effect on individuals and society through direct cost to healthcare and indirectly to the economy in general. To successfully manage chronic daily headache syndromes it is important to exclude secondary causes with comprehensive history and relevant investigations; identify risk factors that predict its development and recognise its sub-types to appropriately manage the condition. Chronic migraine, chronic tension-type headache, new daily persistent headache and medication overuse headache accounts for the vast majority of chronic daily headaches. The scope of this article is to review the primary headache disorders. Secondary headaches are not discussed except medication overuse headache that often accompanies primary headache disorders. The article critically reviews the literature on the current understanding of daily headache disorders focusing in particular on recent developments in the treatment of frequent headaches.

  8. Management of chronic paronychia

    Full Text Available Chronic paronychia is an inflammatory disorder of the nail folds of a toe or finger presenting as redness, tenderness, and swelling. It is recalcitrant dermatoses seen commonly in housewives and housemaids. It is a multifactorial inflammatory reaction of the proximal nail fold to irritants and allergens. Repeated bouts of inflammation lead to fibrosis of proximal nail fold with poor generation of cuticle, which in turn exposes the nail further to irritants and allergens. Thus, general preventive measures form cornerstone of the therapy. Though previously anti-fungals were the mainstay of therapy, topical steroid creams have been found to be more effective in the treatment of chronic paronychia. In recalcitrant cases, surgical treatment may be resorted to, which includes en bloc excision of the proximal nail fold or an eponychial marsupialization, with or without nail plate removal. Newer therapies and surgical modalities are being employed in the management of chronic paronychia. In this overview, we review recent epidemiological studies, present current thinking on the pathophysiology leading to chronic paronychia, discuss the challenges chronic paronychia presents, and recommend a commonsense approach to management.

  9. Lactoferrin in Chronic Pancreatitis

    2009-05-01

    Full Text Available The present review is focused on the clinical significance of lactoferrin in pancreatic secretions and stone formation in chronic pancreatitis, and of serum anti-lactoferrin antibody in autoimmune pancreatitis. Lactoferrin secretion is increased in pancreatic secretions in calcified and non-calcified chronic pancreatitis. Lactoferrin, pancreatic stone protein and trypsin are present in pancreatic stones. We cannot conclude which protein is more important for the precipitate and stone formation. The presence of antilactoferrin antibody has been reported in serum in autoimmune diseases, such as autoimmune pancreatitis. The coincidental appearance of autoimmune pancreatitis with extrapancreatic autoimmune diseases strongly suggests a common autoimmune mechanism and lactoferrin is a candidate antigen. Lactoferrin may play an important role as a precipitate protein in pancreatic stone formation in chronic pancreatitis and as an autoantigen in autoimmune pancreatitis. Further studies are required to better understand the role of lactoferin.

  10. Chronic urticaria: recent advances.

    Science.gov (United States)

    Greaves, Malcolm W; Tan, Kian Teo

    2007-10-01

    Chronic urticaria is an umbrella term, which encompasses physical urticarias, chronic "idiopathic" urticaria and urticarial vasculitis. It is important to recognize patients with physical urticarias as the investigation and treatment differs in important ways from patients with idiopathic chronic urticaria or urticarial vasculitis. Although relatively uncommon, urticarial vasculitis is an important diagnosis to make and requires histological confirmation by biopsy. Underlying systemic disease and systemic involvement, especially of the kidneys, should be sought. It is now recognized that chronic "idiopathic" urticaria includes a subset with an autoimmune basis caused by circulating autoantibodies against the high affinity IgE receptor (FceR1) and less commonly against IgE. Although the autologous serum skin test has been proven useful in prompting search for and characterization of circulating wheal-producing factors in chronic urticaria, its specificity as a screening test for presence of functional anti-FceR1 is low, and confirmation by demonstration of histamine-releasing activity in the patient's serum must be the benchmark test in establishing this diagnosis. Improved screening tests are being sought; for example, ability of the chronic urticaria patient's serum to evoke expression of CD 203c on donor human basophils is showing some promise. The strong association between autoimmune thyroid disease and autoimmune urticaria is also an area of ongoing research. Drug treatment continues to be centered on the H1 antihistamines, and the newer second-generation compounds appear to be safe and effective even in off-label dosage. Use of systemic steroids should be confined to special circumstances such as tapering regimens for acute flare-ups. Use of leukotriene antagonists is becoming popular, but the evidence for efficacy is conflicting. Cyclosporin is also effective and can be used in selected cases of autoimmune urticaria, and it is also effective in non

  11. Physics of the intermediate vector bosons

    International Nuclear Information System (INIS)

    The conversion of the CERN 450 GeV proton synchrotron (SPS) into a proton-antiproton collider was originally proposed in 1976 as a fast and relatively cheap way to produce and detect the weak intermediate Vector Bosons (IVB), W* and Z, by achieving hadronic collisions at an energy large enough to provide observable rates. The properties of such particles had been predicted already in the 60's in the framework of the so-called Standard Model of the unified electroweak theory developed; however, the interest in this theory arose only some years later, following the proof of renormalizability and the first experimental observation of neutrino interactions mediated by Z-exchange. In particular, the experiment obtained a measurement of the weak mixing angle, which allowed a quantitative prediction of the IVB mass values. The CERN Collider project was approved in 1978 and the first bar pp collisions at a total center-of-mass energy (√s) of 546 GeV were observed in 1981. The decay W → eν was first observed among data collected at the end of 1982, and the decay Z → e+e- and Z → μ+μ- were observed a few months later. At present, following two more data-taking runs in 1984 and 1985 at a slightly increased center-of-mass energy (√s = 630 GeV), samples of ∼250 W → eν and ∼30 Z → e+e- events are available from each of the two major experiments (UA1 and UA2), making possible a quantitative comparison of IVB properties with the predictions of the Standard Model. In this article the authors first describe the Standard Model of the unified electroweak theory, and the authors use the theoretical framework to derive the IVB mass values and their decay properties

  12. [Intermediate/high energy nuclear physics

    International Nuclear Information System (INIS)

    We have continued to develop a theoretical framework for the quark and gluon structure of nuclei. Our approach features a successful phenomenological model, the quark cluster model (QCM), and an ambitious program in the non-perturbative solution of quantum field theories. The effort in quantum field theory provides theoretical results to test or replace assumed ingredients of the QCM. By the explicit example of a scalar field theory in 2D we have solved the long-standing problem of how to treat the dynamics of the vacuum in light-front quantization. We now propose to solve the same problem for simple Fermion field theories in 2D such as the Gross-Neveu model. We propose in subsequent years to address QCD in low dimensionality with the purpose of extracting non-perturbative predictions for quark and gluon amplitudes in few baryon systems. Simultaneously with this new effort we will continue to develop extensions and applications of the QCM. We propose to continue predicting phenomena to be observed in high energy particle-nucleus collisions that reflect the rearrangement of quarks and gluons in nuclei. We have completed our analysis of the SLAC E101 and E133 experiments on Deuterium to elucidate the degree to which a six-quark cluster contribution is admissable in the Bjorken x > 1 data. We have completed our development of a parameterized thermal liquid drop model for light nuclei. In addition we have completed a set of predictions for the formation of a ''nuclear stratosphere'' in nuclei created by intermediate energy heavy ion interactions. These results motivate a new investigation of the temperature dependence of the ion-ion potential with particular emphasis on the thermal dependence of the barrier height and radius. We have also shown that a consistent treatment of relativistic effects is important for a theoretical description of the elastic magnetic form factor of 17O. 85 refs

  13. Chronic Insulin Exposure Induces ER Stress and Lipid Body Accumulation in Mast Cells at the Expense of Their Secretory Degranulation Response.

    Directory of Open Access Journals (Sweden)

    William E Greineisen

    Full Text Available Lipid bodies (LB are reservoirs of precursors to inflammatory lipid mediators in immunocytes, including mast cells. LB numbers are dynamic, increasing dramatically under conditions of immunological challenge. We have previously shown in vitro that insulin-influenced lipogenic pathways induce LB biogenesis in mast cells, with their numbers attaining steatosis-like levels. Here, we demonstrate that in vivo hyperinsulinemia resulting from high fat diet is associated with LB accumulation in murine mast cells and basophils. We characterize the lipidome of purified insulin-induced LB, and the shifts in the whole cell lipid landscape in LB that are associated with their accumulation, in both model (RBL2H3 and primary mast cells. Lipidomic analysis suggests a gain of function associated with LB accumulation, in terms of elevated levels of eicosanoid precursors that translate to enhanced antigen-induced LTC4 release. Loss-of-function in terms of a suppressed degranulation response was also associated with LB accumulation, as were ER reprogramming and ER stress, analogous to observations in the obese hepatocyte and adipocyte. Taken together, these data suggest that chronic insulin elevation drives mast cell LB enrichment in vitro and in vivo, with associated effects on the cellular lipidome, ER status and pro-inflammatory responses.

    1974-02-19

    A detailed description is given of the complex pathological picture observed in the case of a worker with 30 years' occupational exposure to lead in an accumulator factory (evolution of the disease, clinical findings, autopsy). In spite of a typical clinical picture, lead is not held responsible for the terminal encephalopathy, in view of the fact that Alzheimer's syndrome was discovered at autopsy. However, the neurovegetative asthenia and progressive kidney disease without hypertonia, but with uraemia, which preceded the encephalopathy are in all probability due to chronic lead poisoning. The article discusses the diagnosis and symptomatology of chronic lead poisoning, encephalopathy and kidney disease.

    2012-01-01

    Full Text Available Measurements of small, intermediate and large ions made onboard ORV Sagarkanya over the Arabian Sea in May-June 2003 during Arabian Sea Monsoon Experiment (ARMEX are reported here. The daily averaged values of small-, intermediate-, and large-ion concentrations measured for 36 days during this cruise have been used for analysis. The analysis shows a weak positive correlation of 0.14 between intermediate- and large-ion concentrations, which indicates that the sources of these two types of ions are different over ocean surface. The negative correlation is observed between small- and intermediate-ion concentration for entire period of cruise. In addition, it is seen that the intermediate-ion concentration shows a very good (=0.58 and significant positive correlation with sea surface pressure. Based on good negative correlation between small- and intermediate-ion concentrations and good positive correlation between intermediate-ion concentration and sea surface pressure, it has been proposed that attachment of small ions to the ultrafine particles transported from upper troposphere to marine boundary layer is the main source of intermediate ions over ocean surface. This study supports the idea that the main source of ultrafine particles over marine boundary layer (MBL is entrainment of aerosol particles from the free troposphere.

  20. Low chronic radiation doses

    International Nuclear Information System (INIS)

    In the context of the Chernobyl and Fukushima accidents where large territories have been contaminated durably and as consequence where local populations are submitted to chronic low radiation doses, IRSN (French institute for radiation protection and nuclear safety) has led various studies to assess the impact of chronic low doses. Studies about the effects of uranium on marine life show that the impact is strongly dependent on the initial state of the individual (zebra Danio rerio fish). The studies about the impact of chronic low doses due to cesium and strontium contamination show different bio-accumulations: 137Cs is found in the animal's whole body with higher concentrations in muscles and kidneys while 90Sr is found almost exclusively in bones and it accumulates more in female mice than in males. The study dedicated to the sanitary impact of chronic low doses on the workers of the nuclear industry shows a higher risk for developing a leukemia, a pleural cancer or a melanoma but no correlation appears between doses and the appearance of the pleural cancer or the melanoma.

    We report here oil the progress that we made for the nine months beginning October 1, 1991 for DOE Grant No. DE-FG05-87ER40309. The report covers the third year of a three year grant. Since we are submitting an accompanying Grant Renewal Proposal, we provide in this report more background information than usual for the different projects. The theme that unites the experiments undertaken by the Bonner Lab Medium Energy Group is a determination to understand in detail the many facets and manifestations of the strong interaction, that which is now referred to as nonperturbative QCD. Whether we are investigating the question of just what does carry the spin of baryons, or the extent of the validity of the SU(6) wavefunctions for the excited hyperons (as will be measured in our CEBAF experiment), or questions associated with the formation of a new state of matter predicted by QCD (the subject of AGS bar p experiment E854, AGS heavy ion experiment E810, as-well as the approved STAR experiment at RHIC), - all these projects share this common goal. FNAL E683 may well open a new field of investigation in nuclear physics: That of just how colored quarks and gluons interact with nuclear matter as they traverse nuclei of different-sizes. In most all of the experiments mentioned, above, the Bonner Lab Group is playing major leadership roles as well as doing a big fraction of the hard work that such experiments require. We use many of the facilities that are available to the intermediate energy physics community and we use our expertise to design and fabricate the detectors and instrumentation that are required to perform the measurements which we decide to do. The format we follow in the Progress Report is,to provide a concise, but fairly complete write-up on each project. The publications listed in Section In give much greater detail on many of the projects. The aim in this report is to focus on the physics goals, the results, and their significance

    Full Text Available The global prevalence of physiologically defined chronic obstructive pulmonary disease (COPD in adults aged >40 yr is approximately 9-10 per cent. Recently, the Indian Study on Epidemiology of Asthma, Respiratory Symptoms and Chronic Bronchitis in Adults had shown that the overall prevalence of chronic bronchitis in adults >35 yr is 3.49 per cent. The development of COPD is multifactorial and the risk factors of COPD include genetic and environmental factors. Pathological changes in COPD are observed in central airways, small airways and alveolar space. The proposed pathogenesis of COPD includes proteinase-antiproteinase hypothesis, immunological mechanisms, oxidant-antioxidant balance, systemic inflammation, apoptosis and ineffective repair. Airflow limitation in COPD is defined as a postbronchodilator FEV1 (forced expiratory volume in 1 sec to FVC (forced vital capacity ratio <0.70. COPD is characterized by an accelerated decline in FEV1. Co morbidities associated with COPD are cardiovascular disorders (coronary artery disease and chronic heart failure, hypertension, metabolic diseases (diabetes mellitus, metabolic syndrome and obesity, bone disease (osteoporosis and osteopenia, stroke, lung cancer, cachexia, skeletal muscle weakness, anaemia, depression and cognitive decline. The assessment of COPD is required to determine the severity of the disease, its impact on the health status and the risk of future events (e.g., exacerbations, hospital admissions or death and this is essential to guide therapy. COPD is treated with inhaled bronchodilators, inhaled corticosteroids, oral theophylline and oral phosphodiesterase-4 inhibitor. Non pharmacological treatment of COPD includes smoking cessation, pulmonary rehabilitation and nutritional support. Lung volume reduction surgery and lung transplantation are advised in selected severe patients. Global strategy for the diagnosis, management and prevention of Chronic Obstructive Pulmonary Disease

    2015-07-01

    The Criegee intermediates, carbonyl oxides proposed by Criegee in 1949 as key intermediates in the ozonolysis of alkenes, play important roles in many aspects of atmospheric chemistry. Because direct detection of these gaseous intermediates was unavailable until recently, previous understanding of their reactions, derived from indirect experimental evidence, had great uncertainties. Recent laboratory detection of the simplest Criegee intermediate CH2OO and some larger members, produced from ultraviolet irradiation of corresponding diiodoalkanes in O2, with various methods such as photoionization, ultraviolet absorption, infrared absorption, and microwave spectroscopy opens a new door to improved understanding of the roles of these Criegee intermediates. Their structures and spectral parameters have been characterized; their significant zwitterionic nature is hence confirmed. CH2OO, along with other products, has also been detected directly with microwave spectroscopy in gaseous ozonolysis reactions of ethene. The detailed kinetics of the source reaction, CH2I + O2, which is critical to laboratory studies of CH2OO, are now understood satisfactorily. The kinetic investigations using direct detection identified some important atmospheric reactions, including reactions with NO2, SO2, water dimer, carboxylic acids, and carbonyl compounds. Efforts toward the characterization of larger Criegee intermediates and the investigation of related reactions are in progress. Some reactions of CH3CHOO are found to depend on conformation. This perspective examines progress toward the direct spectral characterization of Criegee intermediates and investigations of the associated reaction kinetics, and indicates some unresolved problems and prospective challenges for this exciting field of research.

    Nuclear reaction data of intermediate energy ranging above 20 MeV upto a few GeV form an important ingredient of several nuclear energy application, such as medical research, astrophysics, transmutation of radioactive waste and accelerator-driven reactor. Current status of the intermediate energy nuclear data cannot satisfy the requirements of these applications. Despite the fact that theories and models with suitable parameterization and fitting to the experimental data can be used for filling gaps in the available experimental database, current theories and models for intermediate nuclear energy nuclear reaction are still under development. This report summarizes required intermediate energy nuclear data and their physical quantities for the relevant research fields. Theories/models and codes developed up to now for the intermediate nuclear reaction are also outlined and transport codes based on these models are briefly introduced in this report. Available experimental facilities and data libraries are filed and trend of activities in the foreign countries on intermediate energy nuclear data are summarized. It is hoped that this report provide a part of information for the research activity on intermediate energy nuclear data in Korea to establish its long-term plan. (author). 14 tabs., 6 figs

  19. Shelf stable intermediate moisture fruit cubes using radiation technology

    International Nuclear Information System (INIS)

    A process has been developed to prepare shelf stable ready-to-eat (RTE) intermediate moisture pineapple slices and papaya cubes using radiation technology. The combination of hurdles including osmotic dehydration, blanching, infrared drying, and gamma radiation dose of 1 kGy successfully reduced the microbial load to below detectable limit. The shelf life of the intermediate moisture pineapple slices and papaya cubes was found to be 40 days at ambient temperature (28 ± 2 deg C). The control samples spoiled within 6 days. The RTE intermediate moisture fruit products were found to have good texture, colour and sensory acceptability during this 40 days storage. (author)

    In thin-film silicon tandem solar cells consisting of amorphous and microcrystalline silicon, efficiency enhancements can be achieved by increasing the current density in the a-Si:H top cell. Therefore, it is necessary to provide an optimized current matching at high current densities for both junctions. We present a numerical method to obtain suitable intermediate reflections achieving optimal current-matched tandem cells. We used idealized and measured reflection spectra of spectrally-selective intermediate filters for the current matching. For the optical design of such intermediate reflective layers a prediction of the spectral properties towards optimal current matching is presented. (author)

  1. Chronic complicated osteomyelitis

    International Nuclear Information System (INIS)

    Fourteen patients with prior trauma and/or surgery of the lower extremity and suspected active chronic osteomyelitis underwent MR imaging. Eleven patients also underwent In-111 scanning. All patients had surgical confirmation, MR imaging could assess the extent of abnormal marrow and distinguish abnormal marrow due to granulation tissue from active osteomyelitis. The presence and extent of soft-tissue infection could be determined and distinguished from bone involvement in spite of tissue distortion. The course and origin of sinus tracts could be followed. MR imaging was more sensitive to active infection than In-111 scanning. All 11 cases of active osteomyelitis were correctly diagnosed with MR imaging. In-111 scans were positive in only five of the eight cases of active infection in which scans were obtained. MR imaging is useful in chronic complicated osteomyelitis

    Hertzberger-ten Cate, R; Fiselier, T

    1991-10-01

    On basis of clinical and immunogenetic factors most children with pauciarticular juvenile chronic arthritis can be included in one of the subtypes: type 1 and type 2 pauciarticular JCA. Type 1 occurs in young children, mainly girls, with involvement of knees, ankles or elbows. In the majority of children antinuclear antibodies can be detected. The presence of these autoantibodies is associated with chronic anterior uveitis. Type 2 or the juvenile spondylarthropathies include morbus Bechterew, the reactive arthritides and arthritis associated with psoriasis and inflammatory bowel diseases. Large joints of the lower extremities are involved, back pain is unusual at onset, but enthesitis is frequently present. There is a strong association with HLA-B27. Treatment of both subsets consists of non-steroidal anti-inflammatory drugs, application of intra-articular steroids, physio- and hydrotherapy and splinting. In children with a polyarticular course of type 1, or a prolonged course of type 2 disease modifying drugs are often needed. PMID:1957301

  4. Chronic progressive multiple sclerosis

    International Nuclear Information System (INIS)

    A long-lasting immunological suppression action seems to be produced by total lymphoid irradiation; some authors emphasize the favorable effect of this treatment on chronic progressive multiple sclerosis. In order to evaluate the actual role of TLI, 6 patients affected with chronic progressive multiple sclerosis were submitted to TLI with shaped and personalized fields at the Istituto del Radio, University of Brescia, Italy. The total dose delivered was 19.8 Gy in 4 weeks, 1.8 Gy/day, 5d/w; a week elapsed between the first and the second irradiation course. Disability according to Kurtzke scale was evaluated, together with blood lymphocyte count and irradiation side-effects, over a mean follow-up period of 20.8 months (range: 13-24). Our findings indicate that: a) disease progression was not markedly reduced by TLI; b) steroid hormones responsivity was restored after irradiation, and c) side-effects were mild and tolerable

    Persistent cough in children is a symptom, and the cause should be ascertained. Reactive airways disease is the most common reason for chronic cough in children over three to six months of age, especially at night. Under three months, the cause is likely to be more serious. Cough often disturbs parents more than the child, and physicians should consider parents' need for sleep and relief when deciding whether or not to prescribe cough suppressants. Investigations depend on the child's age, th...

    The infection from Epstein-Barr virus (EBV or virus of infectious mononucleosis, together with other herpesviruses’ infections, represents a prototype of persistent viral infections characterized by the property of the latency. Although the reactivations of the latent infection are associated with the resumption of the viral replication and eventually with the “shedding”, it is still not clear if this virus can determine chronic infectious diseases, more or less evolutive. These diseases could include some pathological conditions actually defined as “idiopathic”and characterized by the “viral persistence” as the more credible pathogenetic factor. Among the so-called idiopathic syndromes, the “chronic fatigue syndrome” (CFS aroused a great interest around the eighties of the last century when, just for its relationship with EBV, it was called “chronic mononucleosis” or “chronic EBV infection”.

    Today CFS, as defined in 1994 by the CDC of Atlanta (USA, really represents a multifactorial syndrome characterized by a chronic course, where reactivation and remission phases alternate, and by a good prognosis

    International Nuclear Information System (INIS)

    A comprehensive clinicoroentgenological study was used to examine 494 patients with chronic pneumonia. Morphological and functional changes observed in the pulmonary pare and functional changes observed in the pulmonary parenchyma and bronchial tree were studied. Types of pneumosclerosis, tigns of exacerbation of chronic pneumonia and abscess formation, morphological and functional disorders of bronchial penetrability in the pneumonic zone were described. Three forms of chronic pneumonia: bronchial, bronchiectatic and abscessing are signled out. The bronchial form is subdivided into chronic pneumonia with chronic bronchitis without deformity and wi.th deforming chronic bronchitis. In the bronchiectatic form pneumonia can be with cylindrical, saccular and cyst-like bronchiectasia. The general diagnosis of chronic pneumonia is established clinically depending on type and variants in 89-94% of cases, by X-ray and sonographic findings in all patients; types and variants of disease are most frequently defined after bronchography

    Chronic obstructive pulmonary disease (COPD) is a common disease with high global morbidity and mortality. COPD is characterized by poorly reversible airway obstruction, which is confirmed by spirometry, and includes obstruction of the small airways (chronic obstructive bronchiolitis) and emphysema, which lead to air trapping and shortness of breath in response to physical exertion. The most common risk factor for the development of COPD is cigarette smoking, but other environmental factors, such as exposure to indoor air pollutants - especially in developing countries - might influence COPD risk. Not all smokers develop COPD and the reasons for disease susceptibility in these individuals have not been fully elucidated. Although the mechanisms underlying COPD remain poorly understood, the disease is associated with chronic inflammation that is usually corticosteroid resistant. In addition, COPD involves accelerated ageing of the lungs and an abnormal repair mechanism that might be driven by oxidative stress. Acute exacerbations, which are mainly triggered by viral or bacterial infections, are important as they are linked to a poor prognosis. The mainstay of the management of stable disease is the use of inhaled long-acting bronchodilators, whereas corticosteroids are beneficial primarily in patients who have coexisting features of asthma, such as eosinophilic inflammation and more reversibility of airway obstruction. Apart from smoking cessation, no treatments reduce disease progression. More research is needed to better understand disease mechanisms and to develop new treatments that reduce disease activity and progression. PMID:27189863

  15. Imaging of chronic osteomyelitis

    International Nuclear Information System (INIS)

    The diagnosis of chronic osteomyelitis is made on the basis of clinical, radiologic and histologic findings. The role of imaging in patients with known chronic osteomyelitis is to detect and to delineate areas of active infection. To correctly interpret the imaging findings, it is essential to take both the individual clinical findings and previous imaging studies into account. Reliable signs of active infection are bone marrow abscess, sequestra and sinus tract formation. Only the combined evaluation of bony changes together with alterations of the adjacent soft tissues provides good diagnostic accuracy. Projection radiography gives an overview of the condition of the bone, which provides the basis for follow-up and the selection of further imaging modalities. Computed tomography can be used to evaluate even discrete or complex bony alterations and to guide percutaneous biopsy or drainage. Magnetic resonance imaging achieves the best diagnostic sensitivity and specificity and provides superior contrast as well as anatomical resolution in both bone marrow and soft tissues. In this paper the features and clinical relevance of imaging in primary chronic osteomyelitis, posttraumatic osteomyelitis, tuberculous spondylitis and osteomyelitis of the diabetic foot are reviewed, with particular respect to MRI.

    1999-01-01

    This study examines the influence of financial intermediation on fertility rate and labor allocation decisions. A panel Vector Autoregression model using three variables of interest, specifically, financial intermediation, fertility, and industrial employment data in 87 countries, was estimated. This convenient methodology allows the relationship between the variables to change over time. Findings indicate that the increase in wages led some households to shift from traditional labor intensive methods of production to modern sector firms. Since it is optimal for households in the modern sector to have fewer children then the labor allocation decision leads to a lower national fertility. Furthermore, results imply that the emergence and development of the financial intermediation sector will enhance modern sector employment and lower total fertility rates. Thus, the financial intermediation process is an important part of the overall developmental process. PMID:12349568

    International Nuclear Information System (INIS)

    Secondary sodium loop elimination is proposed for the loop type LMFBR with using Advanced Intermediate Heat Exchanger (AIHX) for reduction in size and cost. This heat exchanger contains primary sodium tubes, and tertiary water tubes in a tank filled with intermediate heat transfer media. A concept verifying experiment was performed with using Ga as the intermediate medium in natural convective region to low velocity forced circulation. From the experimental correlation, AIHX - steam generator was conceptually designed. In order to use Pb or Pb-Bi for intermediate medium, a thermal interaction of Pb and Pb-Bi with water was studied experimentally. Interactions ware found to be suppressed under pressurized condition of two to three bars, and possibility of intense interaction could be ruled out. (authors)

    Thin-film silicon tandem solar cells are composed of an amorphous silicon top cell and a microcrystalline silicon bottom cell, stacked and connected in series. In order to match the photocurrents of the top cell and the bottom cell, a proper photon management is required. Up to date, single-layer intermediate reflectors of limited spectral selectivity are applied to match the photocurrents of the top and the bottom cell. In this paper, we design and prototype multilayer intermediate reflectors based on aluminum doped zinc oxide and doped microcrystalline silicon oxide with a spectrally selective reflectance allowing for improved current matching and an overall increase of the charge carrier generation. The intermediate reflectors are successfully integrated into state-of-the-art tandem solar cells resulting in an increase of overall short-circuit current density by 0.7 mA/cm(2) in comparison to a tandem solar cell with the standard single-layer intermediate reflector.

    Full Text Available To increase the efficiency of a single-junction solar cell the intermediate band solar cell is proposed. Renewable energy sources have become increasingly important; because of global environmental concerns. The intermediate band solar cell (IBSC with potential to enhance the efficiency of the conventional single-junction cell. IBSCs have constraining efficiencies of 63.3%. In this solar cell an intermediate band placed in the band gap between the conduction and valence band. This implies that absorption of photons with energy below the band gap of the semiconductor is possible, and the photocurrent is thus increased. At the point when the carrier concentration in each of the three bands are portrayed by their own semi Fermi level the intermediate band does not influence the voltage if carriers are extricated from the conduction band and the valence band. An increment of proficiency is hence possible.

    After selective extraction and purification, plant keratin intermediate filaments were reassembled in vitro. Scanning tunneling microscope (STM) and transmission electron microscope (TEM) micrographs showed that acidic keratins and basic keratins can assemble into dimers and further into 10 nm filaments in vitro. In higher magnification images, it can be seen that fully assembled plant keratin intermediate filaments consist of several thinner filaments of 3 nm in diameter, which indicates the formation of protofilaments in the assembly processes. One of the explicit features of plant keratin intermediate filaments is a 24—25 nm periodic structural repeat alone the axis of beth the 10 nm filaments and protofilaments. The periodic repeat is one of the fundamental characteristic of all intermediate filaments, and demonstrates the half staggered arrangement of keratin molecules within the filaments.

  6. Noncovalent Intermediate of Thymidylate Synthase: Fact or Fiction?

    Science.gov (United States)

    Kholodar, Svetlana A; Kohen, Amnon

    2016-07-01

    Thymidylate synthase is an attractive target for antibiotic and anticancer drugs due to its essential role in the de novo biosynthesis of the DNA nucleotide thymine. The enzymatic reaction is initiated by a nucleophilic activation of the substrate via formation of a covalent bond to an active site cysteine. The traditionally accepted mechanism is then followed by a series of covalently bound intermediates, where that bond is only cleaved upon product release. Recent computational and experimental studies suggest that the covalent bond between the protein and substrate is actually quite labile. Importantly, these findings predict the existence of a noncovalently bound bisubstrate intermediate, not previously anticipated, which could be the target of a novel class of drugs inhibiting DNA biosynthesis. Here we report the synthesis of the proposed intermediate and findings supporting its chemical and kinetic competence. These findings substantiate the predicted nontraditional mechanism and the potential of this intermediate as a new drug lead. PMID:27327197

  8. Some features of nucleus-nucleus collisions at intermediate energies

    International Nuclear Information System (INIS)

    The so-called intermediate energies are energies for which different reaction mechanisms, intrinsically incompatible, are expected to compete. An energy of a few tens of MeV per nucleon is the limit between two different regimes of nuclear reactions. The characteristics of the changing collision mechanism are detailed in these lectures, particularly through information collected during the first five years of operation of Ganil. Then a synthesis of new nuclear species in intermediate energy heavy ion reactions is given

    2009-01-01

    This paper analyzes the importance of financial intermediation on economic growth. Using the Neoclassical growth framework, we raise a new issue where our model has multiple stationary states with threshold effect. We further confirm that financial intermediation is better than self-financing system in order to ensure the existence and uniqueness of long-run steady state equilibrium of capital stock, as well as to decrease threshold level. The presence of threshold effect is an important find...

    This article develops a search-theoretic model of financial intermediation to study the efficiency condition of the banking sector. Competitive financial intermediation is determined by the search decisions of both households (to find adequate financial products) and banks (to attract depositors through marketing and to select borrowers through auditing) and by the interest rate setting mechanism. The efficiency of the competitive economy requires that interest rates are posted by banks or ar...

    The stability of excitation control systems is of great concern in power system operations. In this paper, the effects of intermediate load on performance limitation in excitation control are studied. The results reveal that the open-loop characteristic of synchronous machines flux linkage can be changed from minimum to non-minimum phase at a high level of intermediate load. This change leads to instability of synchronous machines under manual excitation control. A particular emphasis is also...

    Chinese banks generate large profits and have relatively low nonperforming loans. However, good financial performance does not, in itself, guarantee that banks efficiently intermediate the economy's financial resources. This paper first examines how efficient Chinese banks are in financial intermediation, using the stochastic production frontier approach. Quality of loans are controlled for by focusing on net loans and correcting for nonperforming loans; Hong Kong SAR banks are included in th...

    We present a formulation of the deformed oscillator algebra which leads to intermediate statistics as a continuous interpolation between the Bose-Einstein and Fermi-Dirac statistics. It is deduced that a generalized permutation or exchange symmetry leads to the introduction of the basic number and it is then established that this in turn leads to the deformed algebra of oscillators. We obtain the mean occupation number describing the particles obeying intermediate statistics which thus establ...

    We analyze an overlapping generations economy where agents interact to share liquidity risk. We show that a pure exchange economy has excessive trade in equilibrium, and that intergenerational financial intermediaries reduce the number of interactions by catering to clienteles with uncorrelated liquidity needs. In the intermediated economy equilibrium, intermediaries finance redemptions with loan income, and never sell assets. If the economy is subject to transaction costs, the intermediated ...

These measures should increase competition and reduce inefficiency in the banking system both resulting in lower costs of financial intermediation. However, the cost of financial intermediation has not only remained hig...

  4. On Physical and Mechanical Behavior of Natural Marine Intermediate Deposites

    SHI Ming-lei; DENG Xue-jun

    2005-01-01

    Coastal structures may be built on natural sedimentary intermediate grounds, which mainly consist of silty soils and fine sandy soils. In this study, extensive field and laboratory tests were performed on the natural marine intermediate deposits to demonstrate the difference in behavior between natural marine clayey soils and natural marine intermediate deposits. The natural intermediate deposits have almost the same ratios of natural water content to liquid limit as those of the soft natural marine clays, but the former have much higher in-situ strength and sensitivity than the latter. The research results indicate that grain size distributions of soils affect significantly tip resistance obtained in field cone penetration tests. The mechanical parameters of natural marine intermediate deposits are also significantly affected by sample disturbance due to their high sensitivity and relatively large permeability. Unconfined compression shear tests largely underestimate the strength of natural marine intermediate soils. The triaxial consolidated compression shear tests with simulated in-situ confined pressure give results much better than those of uncomfined compression shear tests.

    Trephination or trepanation is an intentional surgical procedure performed from the Stone Age. It looks like escaping a black evil from the head. This technique is still used for treatment of chronic subdural hematoma (SDH). Now, we know the origin, pathogenesis and natural history of this lesion. The author try to explore the history of trephination and modern discovery of chronic SDH. The author performed a detailed electronic search of PubMed. By the key word of chronic SDH, 2,593 articles were found without language restriction in May 2015. The author reviewed the fact and way, discovering the present knowledge on the chronic SDH. The first authentic report of chronic SDH was that of Wepfer in 1657. Chronic SDH was regarded as a stroke in 17th century. It was changed as an inflammatory disease in 19th century by Virchow, and became a traumatic lesion in 20th century. However, trauma is not necessary in many cases of chronic SDHs. The more important prerequisite is sufficient potential subdural space, degeneration of the brain. Modifying Virchow's description, chronic SDH is sometimes traumatic, but most often caused by severe degeneration of the brain. From Wepfer's first description, nearly 350 years passed to explore the origin, pathogenesis, and fate of chronic SDH. The nature of the black evil in the head of the Stone Age is uncovering by many authors riding the giant's shoulder. Chronic SDH should be categorized as a degenerative lesion instead of a traumatic lesion. PMID:27169062

    [ Objective ] To determine the effects of insulin induced by hyperglycemia on the production of sTM in human umbilical vein endothelial cells ( HUVEC) and the possible mechanisms. [Methods] HUVEC which were cultured in vitro were divided into glucose (Glu) group (5.5,20 and 40 mmol/L), insulin group (10 IU/mL insulin + 40 mmol/L glucose )and control group ( not including glucose and insulin). The cell supernatant was collected at different time(0,6,24,48 and 72 h) and the level of sTM were detected by ELBA ( enzyme linked immunosorbent assay ). And at the same time, the effect of Activated partial thromboplastin time (APTT) mixed proportion with the cell supernatant from normal blood was assayed. [Results] The level of sTM of HUVEC at high concentration of Clu (40 mmol/L)was higher than that of control group and it increased with time going by after the cells exposed for 48 h(P< 0.05). But the level of sTM decreased after the cells exposed for 72 h(P < 0.05). The level of APTT at high concentration of Glu(40 mmol/L)was lower than that of control group and it decreased with time going by (P< 0.01 )The level of sTM at high concentration of Glu with insulin was lower than the level of those cultured with Glu (P < 0.05). The level of APTT at high concentration of Glu with insulin increased with time going by, it was still lower than that of control group (P< 0.01). [Conclusion] Insulin can reduce sTM level and inhibit the damage effect of high concentration Glu on HUVEC.%[目的]研究胰岛素对高糖诱导的人脐静脉内皮细胞可溶性血栓调节蛋白(solubility Thrombomodulin,sTM)分泌的影响和可能机制.[方法]将体外培养的人脐静脉内皮细胞分为葡萄糖组(5.5、20和40 mmol/L)、胰岛素组(10 IU/mL)、高糖(40mmol/L)环境下的胰岛素组(10 IU/mL)和对照组(不含葡萄糖和胰岛素),于0、6、24、48和72h等不同时间点收集细胞上清液,采用ELISA法双抗体夹心法检测sTM水平,同时将各时间的细胞上

    Comprehensive analysis of chronic radiation syndrome, covering epidemiology, pathogenesis, pathoanatomy, diagnosis and treatment. Based on observations in a unique sample of exposed residents of the Techa riverside villages in the Urals. Casts new light on the condition. Of value for all practitioners and researchers with an interest in chronic radiation syndrome. This book covers all aspects of chronic radiation syndrome (CRS) based on observations in a unique sample of residents of the Techa riverside villages in the southern Urals who were exposed to radioactive contamination in the 1950s owing to releases of liquid radioactive wastes from Mayak Production Association, which produced plutonium for weapons. In total, 940 cases of CRS were diagnosed in this population and these patients were subjected to detailed analysis. The opening chapters address the definition and classification of CRS, epidemiology and pathogenesis, covering molecular and cellular mechanisms, radioadaptation, and the role of tissue reactions. The pathoanatomy of CRS during the development and recovery stages is discussed for all organ systems. Clinical manifestations of CRS at the different stages are then described in detail and the dynamics of hematopoietic changes are thoroughly examined. In the following chapters, principles of diagnosis (including assessment of the exposure doses to critical organs) and differential diagnosis from a wide range of other conditions are discussed and current and potential treatment options, described. The medical and social rehabilitation of persons with CRS is also covered. This book, which casts new light on the condition, will be of value for all practitioners and researchers with an interest in CRS.

    2009-06-01

    Chronic urticaria is defined as the presence of urticaria (hives) for at least 6 weeks with the assumption that it occurs daily or close to it. If we eliminate physical urticarias and urticarial vasculitis from consideration, the remainder can be divided into autoimmune chronic urticaria (45%) and idiopathic chronic urticaria (55%). The autoimmune subgroup is associated with the IgG anti-IgE receptor alpha subunit in 35-40% of patients and IgG anti-IgE in an additional 5-10%. These autoantibodies have been shown to activate blood basophils and cutaneous mast cells in vitro with augmentation of basophil activation by complement and release of C5a, in particular. Binding methods (immunoblot and ELISA) yield positives in many autoimmune diseases as well as occasional normal subjects or patients with other forms of urticaria but most such sera are non-functional. Activation of basophils or mast cells causing histamine release is quite specific for chronic urticaria and defines the autoimmune subgroup. Although pathogenicity is not formally proven, the antibodies cause wealing upon intradermal injection, and removal of the autoantibody leads to remission. A cellular infiltrate is seen to be characterized by mast cell degranulation and infiltration of CD4+ T lymphocytes, monocytes, neutrophils, eosinophils, and basophils. The intensity of the infiltrate and clinical severity of the disease (including accompanying angio-oedema) is more severe in the autoimmune subpopulation. This latter group also has a higher evidence of human leucocyte antigen DR alleles associated with autoimmunity and a 25% incidence of antithyroid antibodies with diagnosed hypothyroidism in some. Hypo-responsiveness of patients' basophils to anti-IgE and hyperresponsiveness to serum defines another subpopulation (at least 50%) that overlaps the idiopathic and autoimmune subgroups. Hypo-responsiveness to anti-IgE has been shown to be associated with elevated levels of cytoplasmic phosphatases that

    Chronic nonbacterial osteomyelitis is an autoinflammatory disease occurring mainly in children and adolescents, typically involving recurrent or persistent osteitic foci. The symptom is bone pain, possibly accompanied by soft tissue tenderness. Some patients exhibit symptoms of systemic inflammation. The. precise etiology of the disease is not known, but an imbalance of inflammatory and anti-inflammatory cytokines is presumed to play a role in the development of the disease. While an anti-inflammatory analgesic is in most cases sufficient to calm down the osteitis, the use of corticosteroids, anti- TNF-a inhibitors or bisphosphonates is required in some cases.

    Sexual function is often affected in individuals living with chronic illness and their partners, and multiple comorbidities increase the likelihood of sexual dysfunction. This review focuses on the areas of cardiovascular disease, respiratory conditions, and cancer, all areas for which there are practical, evidence-based strategies to guide sexual counseling. Although nurses have been reluctant to address the topic of sexuality in practice, a growing number of studies suggest that patients want nurses to address their concerns and provide resources to them. Thus, nurses must be proactive in initiating conversations on sexual issues to fill this gap in practice. PMID:24066783

    Chronic sinusitis is a burdensome disease that has substantial individual and societal impact. Although great advances in medical and surgical therapies have been made, some patients continue to have recalcitrant infections. Microbial biofilms have been implicated as a cause of recalcitrant chronic sinusitis, and recent studies have tried to better understand the pathogenesis of chronic sinusitis as it relates to microbial biofilms. Here, we provide an overview of biofilms in chronic sinusitis with emphasis on pathogenesis, treatment, and future directions. In addition, recent evidence is presented, elucidating the role of bitter taste receptors as a possible key factor leading to biofilm formation. PMID:26758863

    2006-04-01

    Full Text Available Abstract Idiopathic chronic eosinophilic pneumonia (ICEP is characterized by subacute or chronic respiratory and general symptoms, alveolar and/or blood eosinophilia, and peripheral pulmonary infiltrates on chest imaging. Eosinophilia is present in most cases, usually in excess of 1000/mm3. In absence of significant blood eosinophilia, a diagnosis of ICEP is supported by the demonstration of bronchoalveolar lavage eosinophilia. ICEP is typically associated with eosinophil counts higher than lymphocyte counts in the bronchoalveolar lavage. ICEP is a rare disorder of unknown cause. Its exact prevalence remains unknown. ICEP may affect every age group but is rare in childhood. It is twice as frequent in women as in men. One third to one half of the ICEP patients have a history of asthma. The mainstay of treatment of ICEP is systemic corticosteroids. Response to oral corticosteroid therapy is dramatic and has led to the consideration of corticosteroid challenge as a diagnostic test for ICEP. Nevertheless, relapses or development of severe asthma are frequent when tapering or withdrawing treatment. Long-term oral corticosteroid therapy is necessary in up to half of the patients.

    Chronic wound toilet, with appropriate care of the surrounding skin, is one of the basic steps that must be performed in the treatment of patients with chronic wound. On wound cleaning and bandaging, it is of utmost importance to choose an appropriate technique of cleansing, select an appropriate solution for leaching and choose an appropriate wound dressing. In this way, the wound is protected from dirt from the environment and microorganisms, while protecting the surrounding tissue from the wound exudate, providing optimal conditions for better and faster wound healing and contributing to improved patient quality of life. The frequency of dressing change is individual and must be tailored to each patient in correlation with the psychosocial status of the patient, the type of the wound, the amount and type of wound exudate, as well as what is to be put on the wound. One of the most important elements in wound toilet is appropriate care for the surrounding skin. Basic guidelines for skin care must meet three basic criteria: adequate washing and cleansing of the skin, maintain the physiological balance of the skin and protect the skin from external damage.

    Infection with hepatitis C virus (HCV) accounts for 40% of cases of chronic liver disease in the United States and is now the most common indication for liver transplantation. Estimates suggest that 4 million people (1.8%) of the American population are or have been infected with HCV. Currently, the treatment of choice for patients with chronic HCV infection is recombinant interferon alfa with ribavirin. Pegylated interferons are a promising new development, and in combination with ribavirin, they will rapidly become the standard of care. The goals of therapy are to slow disease progression, improve hepatic histology, reduce infectivity, and reduce the risk of hepatocellular carcinoma. Sustained virologic response, which generally implies the absence of viremia for 6 months or more following completion of therapy, is increasingly being regarded as a cure, with evidence of slowing or even regression of fibrosis on follow-up liver biopsy. A number of factors have been shown to be predictive of a sustained response, including viral genotype other than 1, low serum HCV RNA levels, absence of cirrhosis, younger age, female gender, and shorter duration of infection. Disease severity as assessed by liver biopsy, comorbidities, and possible contraindications to therapy should be weighed in the decision to begin treatment. Counseling patients regarding transmission, natural history, and drug and alcohol abstinence also should be included in management. Close monitoring should be done during treatment for side effects of interferon, including depression and bone marrow suppression. Hemolytic anemia is the major side effect of ribavirin.

  6. The chronic leukaemias

    Full Text Available The slow progression of both chronic granulocytic and lymphocytic leukaemia, when compared to their acute counterparts, has been used as an argument to support less aggressive therapy or even, in some instances, a watch-and-wait policy. This conservative approach is bolstered by a number of observations including the ease with which haematologic control can initially be achieved, the older age of patients with the lymphocytic variant and the paucity of controlled data showing that long disease-free survival or cure can result from the use of aggressive treatment. Given these circumstances, it is not surprising that many such individuals are managed outside specialised centres using a variety of agents and schedules, both of which may, on occasions, be inappropriate. Accumulating evidence suggests a need to reconsider these practices since cure is now possible in selected patients with chronic granulocytic leukaemia while the use of multi-drug regimens in the lymphatic form can significantly improve survival. These advances are the result of carefully conducted clinical trials involving many individuals the world over and constitute the basis fo r advocating early referral to those institutions where all the necessary expertise is available.

  7. Canine chronic inflammatory rhinitis.

    Windsor, Rebecca C; Johnson, Lynelle R

    2006-05-01

    Chronic inflammatory rhinitis is commonly found in dogs with chronic nasal disease and is characterized by lymphoplasmacytic infiltrates in the nasal mucosa in the absence of an obvious etiologic process. The pathogenesis of lymphoplasmacytic rhinitis remains unknown. Animals respond poorly to antibiotics, oral glucocorticoids, and antihistamines, making primary infectious, immune-mediated, or allergic etiologies unlikely. Aberrant immune response to inhaled organisms or allergens may induce inflammation in some animals. Common clinical signs include nasal discharge, sneezing, coughing, epistaxis, and stertor. Diagnosis is made by performing a thorough history, physical examination, radiography or advanced imaging (via computed tomography or magnetic resonance imaging), rhinoscopy, and nasal mucosal biopsy to rule out primary etiologies of nasal discharge. Treatment strategies have included various antibiotics, antihistamines, oral and inhalant steroids, nonsteroidal antiinflammatories, and antifungal medications. Some dogs may respond partially to doxycycline or azithromycin, although it is unclear whether response is related to antimicrobial or antiinflammatory properties of these drugs. Hydration of the nasal cavity through nasal drops or aerosols may limit nasal discharge, and some animals may improve with inhalant (but rarely oral) glucocorticoids. PMID:16711613

  8. Algorithm for Route Planning with Multiple Intermediate Destinations

    Science.gov (United States)

    Mainali, Manoj Kanta; Mabu, Shingo; Hirasawa, Kotaro

    The optimal route recommendation in navigation systems is often considered to be the optimal route recommendation between two locations, i.e., an origin and a destination. However, in practical scenarios, traveling to several intermediate destinations before the final destination needs to be considered. Conventional route search algorithms cannot consider such restrictions in the route search. In this paper, a method to find the optimal route via several intermediate destinations is proposed. The proposed method is divided into three steps. In the first step, the conventional route search algorithm is used to find the optimal traveling time and optimal route among the origin, intermediate destinations and final destination. In the second step, the visiting order of the intermediate destination is optimized using the population based RasID-D (RasID-DP) to minimize the total traveling time. Finally, the optimal route from the origin to destination is determined based on the results of the previous steps. The proposed method is evaluated based on the efficiency of the optimization of the visiting order of intermediate destinations. Simulation results show that RasID-DP based optimization can find better solutions efficiently.

  9. Top predators induce the evolutionary diversification of intermediate predator species.

    We analyze the evolutionary branching phenomenon of intermediate predator species in a tritrophic food chain model by using adaptive dynamics theory. Specifically, we consider the adaptive diversification of an intermediate predator species that feeds on a prey species and is fed upon by a top predator species. We assume that the intermediate predator׳s ability to forage on the prey can adaptively improve, but this comes at the cost of decreased defense ability against the top predator. First, we identify the general properties of trade-off relationships that lead to a continuously stable strategy or to evolutionary branching in the intermediate predator species. We find that if there is an accelerating cost near the singular strategy, then that strategy is continuously stable. In contrast, if there is a mildly decelerating cost near the singular strategy, then that strategy may be an evolutionary branching point. Second, we find that after branching has occurred, depending on the specific shape and strength of the trade-off relationship, the intermediate predator species may reach an evolutionarily stable dimorphism or one of the two resultant predator lineages goes extinct.

  10. An improved intermediate resonance method for heterogeneous media

    International Nuclear Information System (INIS)

    A new formulation is described of the Intermediate Resonance method which incorporates the previous developments suitably modified and improved, together with some new contributions. The 'intermediate' character is directly introduced in the integral operator K, allowing a more rigorous deduction of the equations for evaluating the intermediate parameters related to the nuclides involved in the system. There is no limit to the number of internal (admixed in the fuel) and external moderators. The capability to take into account the interference scattering has been extended to heterogeneous systems. The Doppler broadening is described by means of new accurate rational approximations to the broadened line shape psi. Finally the use of energy mean values suitably defined refines the values of the resonance integrals and resonance absorption cross sections. The Intermediate Resonance method so extended and improved, has been coded in a group of FORTRAN routines, which have been inserted as a calculation option in the fast section of the GGC code for the evaluation of multigroup cross sections. A series of calculations has been carried out, using these routines, and comparisons have been made with Monte Carlo and Nordheim's methods. The results obtained show that the Intermediate Resonance method developed in the present work offers considerable advantages over Nordheim's method: better accuracy in evaluating resonance absorption cross sections, and much smaller computing times.

  11. Clinical Scenarios in Chronic Kidney Disease: Chronic Tubulointerstitial Diseases.

    Meola, Mario; Samoni, Sara; Petrucci, Ilaria

    2016-01-01

    Chronic tubulointerstitial diseases are a common final pathway toward chronic renal failure regardless the primary damage (glomerular, vascular or directly the tubulointerstitium). Chronic tubulointerstitial nephritis (CTN) is characterized by interstitial scarring, fibrosis and tubule atrophy, resulting in progressive chronic kidney disease. Most frequent causes of CTN are drugs, heavy metals, obstructive uropathy, nephrolithiasis, reflux disease, immunologic diseases, neoplasia, ischemia, metabolic diseases, genetics and miscellaneous. At ultrasound (US), kidneys' morphological aspect is similar in all forms of chronic interstitial nephropathy and only chronic pyelonephritis with or without reflux shows distinguishing characteristics. In interstitial nephropathy, kidneys' profiles are finely irregular and corticomedullary differentiation is altered because of a diffused hyperechogenicity. The only indirect sign of chronic interstitial damage can be derived from the value of intrarenal resistive indexes that hardly overcome 0.75. US is mandatory in clinical chronic pyelonephritis work-up because it provides information on kidney's diameter and on growth nomogram in children. Renal profiles can be more or less altered depending on the number of cortical scars and the presence of pseudonodular areas of segmental compensatory hypertrophy. In the early stages, US diagnosis of renal tuberculosis is difficult because parenchymal lesions are non-specific. US sensitivity in the diagnosis of hydronephrosis is very high, close to 100% and, finally, US is the first choice imaging technique in the diagnosis of urinary lithiasis. PMID:27169608

    Full Text Available We use the CoRoT-survey to search for transiting close-in planets of intermediate-mass stars (M* = 1.3 − 2.1 M⊙. We present recent results of our survey. RV-surveys and direct imaging campaigns showed, that intermediate-mass main-sequence stars have more massive planets then solar-like stars. Even brown dwarfs have been found. In our study we concentrated on short-period planets for which a mass-determination is possible. The detection of close-in planets of intermediate-mass stars put strong constraints on the timescales of the formation and migration. We already have identified transiting Jupiter-like planet candidates with short orbital periods and observed these candidates with high-resolution echelle-spectrographs at various Telescopes.

  14. Characterization of the Partially Folded Monomeric Intermediate of Creatine Kinase

    2002-01-01

    The importance of understanding the protein folding pathway and intermediates is well recognized on the basis of extensive studies of protein folding in vitro and in vivo. Creatine kinase (CK) is a typical model for studying unfolding and refolding of proteins due to several interesting properties. Recent studies on the folding of CK show that its partially folded monomeric intermediate is present kinetically and is stable at equilibrium. The present paper contains 33 References as a mini review to characterize the properties of CK from studies on the CK folding pathway. Characterization of these intermediates is an essential step toward understanding the mechanism of protein folding. Some well-determined schemes are suggested as protein folding models.

  15. Hybrid songbirds employ intermediate routes in a migratory divide.

    Delmore, Kira E; Irwin, Darren E

    2014-10-01

    Migratory divides are contact zones between populations that use different routes to navigate around unsuitable areas on seasonal migration. Hybrids in divides have been predicted to employ intermediate and potentially inferior routes. We provide the first direct test of this hypothesis, using light-level geolocators to track birds breeding in a hybrid zone between Swainson's thrushes in western Canada. Compared to parental forms, hybrids exhibited increased variability in their migratory routes, with some using intermediate routes that crossed arid and mountainous regions, and some using the same routes as one parental group on fall migration and the other on spring migration. Hybrids also tended to use geographically intermediate wintering sites. Analysis of genetic variation across the hybrid zone suggests moderately strong selection against hybrids. These results indicate that seasonal migratory behaviour might be a source of selection against hybrids, supporting a possible role for migration in speciation. PMID:25040456

  16. Intermediate Collaborative Adaptive Management Strategies Build Stakeholder Capacity

    Directory of Open Access Journals (Sweden)

    Martha C. Monroe

    2013-06-01

    Full Text Available Efforts to implement collaborative adaptive management (CAM often suffer from challenges, such as an unwillingness of managers to share power, unresolved conflicts between stakeholders, and lack of capacity among stakeholders. Some aspects considered essential to CAM, e.g., trust and stakeholder capacity, may be more usefully viewed as goals for intermediate strategies rather than a set of initial conditions. From this perspective, intermediate steps that focus on social learning and building experience could overcome commonly cited barriers to CAM. An exploration of Springs Basin Working Groups, organized around major clusters of freshwater springs in north Florida, provides a case study of how these intermediate steps enable participants to become more reasonable and engaged. This strategy may be easily implemented by agencies beginning a CAM process.

  17. Reduction of quantum phase fluctuations in intermediate states

    International Nuclear Information System (INIS)

    Recently we have shown that the reduction of the Carruthers-Nieto symmetric quantum phase fluctuation parameter (U) with respect to its coherent state value corresponds to an antibunched state, but the converse is not true. Consequently reduction of U is a stronger criterion of nonclassicality than the lowest order antibunching. Here we have studied the possibilities of reduction of U in intermediate states by using the Barnett-Pegg formalism. We have shown that the reduction of phase fluctuation parameter U can be seen in different intermediate states, such as binomial state, generalized binomial state, hypergeometric state, negative binomial state, and photon added coherent state. It is also shown that the depth of nonclassicality can be controlled by various parameters related to intermediate states. Further, we have provided specific examples of antibunched states, for which U is greater than its Poissonian state value.

    2013-07-01

    Full Text Available The importance of intermediate water masses in climate change and ocean circulation has been emphasized recently. In particular, Antarctic Intermediate Water (AAIW is thought to have acted as an active interhemispheric transmitter of climate anomalies. Here we reconstruct changes in AAIW signature and spatial and temporal evolution based on a 40 kyr time series of oxygen and carbon isotopes as well as planktic Mg/Ca based thermometry from a site in the western Indian Ocean. Our data suggest that AAIW transmitted Antarctic temperature trends to the equatorial Indian Ocean via the "oceanic tunnel" mechanism. Moreover, our results reveal that deglacial AAIW carried a signature of aged Southern Ocean deep water. We find no evidence of increased formation of intermediate waters during the deglaciation.

  19. Intermediate-energy neutron beam for NCT at MURR

    International Nuclear Information System (INIS)

    The University of Missouri Research Reactor (MURR) is one of the high-flux reactors in the USA and it can be used to produce an intense beam of intermediate-energy neutrons for neutron capture therapy. Two methods are being evaluated at MURR to produce such a beam. The first uses a moderator of Al2O3 replacing part of the graphite and water on one side of the core of the reactor to produce a source of predominantly intermediate-energy neutrons. The second method is a filter of 238U between the core and the patient position to pass only intermediate-energy neutrons. The results of these evaluations are presented in this paper along with an outline of the other resources at the University of Missouri-Columbia that are available to support an NCT program. 4 references, 7 figures, 1 table

  20. Folate Deficiency in Chronic Pancreatitis

    2010-07-01

    Full Text Available Dear Sir, While there has been a spurt of interest in genetic alterations associated with pancreatitis in the past few years, interest in the role of environmental factors has largely focused on alcoholism and smoking with insufficient attention being paid to the contributions of nutritional deficiency, and the role of environmental toxins in the pathogenesis of pancreatitis. Braganza and Dormandy [1] argue convincingly about the role played by cytochrome P450 monooxygenases (especially CYP1A enzyme induction by xenobiotics and the resultant oxidative stress, as also the now increasingly recognized reductive stress posed by the metabolites in initiating pancreatic injury. Their article underlines the important part played by the deficiency of methyl and thiol molecules in different stages of the progression of pancreatic damage. Furthermore, they attempt to establish a link between environmental and genetic factors and bring in a holistic view on the etiopathogenesis of chronic pancreatitis. We have recently demonstrated lower plasma methionine levels in two cohorts of chronic pancreatitis patients; one of tropical chronic pancreatitis and the other, of alcoholic chronic pancreatitis as compared to healthy controls [2] which suggests that deficiency of methyl groups may be a factor in various forms of pancreatitis. Similarly, we have shown lower red cell glutathione levels in chronic pancreatitis patients with tropical chronic pancreatitis and alcoholic chronic pancreatitis, indicating deficiency of thiol molecules. In addition, we have demonstrated significantly higher levels of plasma total homocysteine in chronic pancreatitis patients than in healthy controls. Moreover, our study has shown that there is a deficiency of red cell folate in the majority of chronic pancreatitis patients, more so in tropical chronic pancreatitis; and that folate deficiency appeared to be the key factor in hyperhomocysteinemia in chronic pancreatitis patients

  1. Negotiating comfort in low energy housing: The politics of intermediation

    International Nuclear Information System (INIS)

    Optimising the energy performance of buildings is technically and economically challenging but it also has significant social implications. Maintaining comfortable indoor conditions while reducing energy consumption involves careful design, construction, and management of the built environment and its inhabitants. In this paper, we present findings from the study of a new low energy building for older people in Grenoble, France where conflicts emerged over the simultaneous pursuit of energy efficiency and comfort. The findings contribute to the contemporary literature on the sociotechnical study of buildings and energy use by focusing on intermediation, those activities that associate a technology to end users. Intermediation activities take many forms, and in some cases, can result in the harmonisation or alignment of energy efficiency goals and comfort goals. In other cases, intermediation is unsuccessful, leading to the conventional dichotomy between optimising technical performance and meeting occupant preferences. By highlighting the multiple ways that comfort and energy efficiency is negotiated, we conclude that buildings are provisional achievements that are constantly being intermediated. This suggests that building energy efficiency policies and programmes need to provide opportunities for intermediaries to negotiate the desires and preferences of the multiple stakeholders that are implicated in low energy buildings. -- Highlights: •Energy efficiency and comfort are two possibly contradictory aims of buildings. •We study the pursuit of these aims at the occupation stage of a new building. •Aligning these aims involve negotiating them with occupants. •Intermediation processes are key to such negotiations. •Intermediation processes involve both actors and technical devices

    Chalcopyrite-based solar cells currently lead the efficiency tables of thin-film photovoltaic technologies. Further improvements are foreseen upon implementation of an intermediate band in the absorber layers. We present a theoretical analysis of the efficiency limit for this type of device as a function of factors such as the gap of the host, the relative position of the intermediate band with respect to the band edge and the level of light concentration used as illumination. We have also considered the impact of non-idealities on the performance of the device, particularly the effect of electronic losses related to non-radiative recombination

    Picosecond and subpicosecond spectroscopic studies have revealed evidence for an isomerization intermediate between cis and trans in the photoinduced isomerism of both stilbene and biindanyledene ("stiff" stilbene). In stiff stilbene, a transient absorption at 351 nm displays time evolution and viscosity dependence consistent with absorption by a twisted intermediate ("phantom" state) with a lOps lifetime. An analagous bottleneck state with a life-time of 4ps is also consistent with the ground state recovery dynamics of t-stilbene following excitation of c-stilbene when monitored with 0.1ps resolution.

    1985-01-01

    A general approach to determining the correct intermediate boundary conditions for dimensional splitting methods is presented. The intermediate solution U is viewed as a second order accurate approximation to a modified equation. Deriving the modified equation and using the relationship between this equation and the original equation allows us to determine the correct boundary conditions for U*. This technique is illustrated by applying it to locally one dimensional (LOD) and alternating direction implicit (ADI) methods for the heat equation in two and three space dimensions. The approximate factorization method is considered in slightly more generality.

We focus on the non-spinning intermediate mass black hole located less than 100 Mpc from earth. By comparing two simulation waveforms (effective one body numerical relativity waveform (EOBNR), phenomenological waveform), we discuss the relationship between the effective distance and frequency; and through analyzing large amounts of data in event, we find that the phenomenological waveform is much smoother than EOBNR waveform, and has higher accuracy at the same effective distance.

The lungs are the most commonly affected organ; however, lymphatic, hepatic, skeletal, gastrointestinal, genitourinary, head and neck, and central nervous system involvement have also been described. Most patients present with symptoms in their first few years of life. Due to the nonspecific manner in which patients present, the pediatric radiologist may be among the first to recognize the pattern of infection, inflammation, and granuloma formation leading to a diagnosis of CGD. The purpose of this paper is to review the imaging findings of CGD that can manifest throughout the body. (orig.)

    Chronic cough is one of the most common reasons for referral to a respiratory physician. Although fatal complications are rare, it may cause considerable distress in the patient's daily life. Western and local data shows that in patients with a normal chest radiograph, the most common causes are postnasal drip syndrome, postinfectious cough, gastro-oesophageal reflux disease and cough variant asthma. Less common causes are the use of angiotensin-converting enzyme inhibitors, smoker's cough and nonasthmatic eosinophilic bronchitis. A detailed history-taking and physical examination will provide a diagnosis in most patients, even at the primary care level. Some cases may need further investigations or specialist referral for diagnosis. PMID:26892615

    The process of chronic hypophosphatemic vitamine D-resistant rickets is described by observation of two cases. With the male patient - our first case - the disease was sporadic and had not been recognized for a long time. In his early adulthood it manifested itself as Umbauzonen (pseudofractures) in the larger context of active osteomalacia. It was possible to observe the pseudofractures before and while the patient was medicamentously treated. High doses of vitamine D 3 and dosage of phosphate mitigated the complaints although with respect to the radiological, scintigraphical, humoral and histological findings there was only slow improvement or no improvement at all. The patient's daughter is affected by the disease as well. In her case the pathological signs of her bones became better when treated with vitamine D 3.

  20. 'Chronic' identities in mental illness.

    Science.gov (United States)

    von Peter, Sebastian

    2013-04-01

    The term 'chronicity' is still widely used in psychiatric discourse and practice. A category employed in political, administrative and therapeutic contexts, it guides practitioners' beliefs and actions. This paper attempts a review of the attitudes and procedures that result as a consequence of identifying 'chronically' disturbed identities in clinical practice. An essentially social, relational and materialist understanding of mental illness is used to highlight the kind of thinking underlying the notion of 'chronic' identities in day-to-day psychiatric routines. Problematising the notions of singularity and expressiveness, as well as mind/body- and self/other-distinctions, it claims the category itself is responsible for creating a 'chronic' kind of being. A spatial metaphor is presented in the conclusion, illustrating a mental strategy by which we can re-shape our thinking about 'chronic' identities. It attempts to describe how the shift from an epistemological to a praxeographic approach could build a more complete understanding of mental illness. PMID:23528064

    The structure of sodium ultraphosphate glasses, (Na{sub 2}O){sub x}(P{sub 2}O{sub 5}){sub 100-x} (x = 0, 10, 20), and alkali metaphosphate glasses, MePO{sub 3} (Me = Li, Na, K, Rb and Cs) have been studied by neutron diffraction. Structural features in the neutron structure factors S(Q) characteristic of intermediate-range (Q {approx_lt} 3 {angstrom}{sup -1}) order were identified. The feature of intermediate-range order in the pure phosphate glass (v-P{sub 2}O{sub 5}) is accounted for by the P{sub 4}O{sub 10} molecule packing model. The addition of the alkali metal modifier, Na, has drastic affect on the intermediate-range structure due to destruction of the PO{sub 4} network structure. Around x {approximately} 50 a new peak arises at lower Q than the intermediate-range order peak, which is found in the S(Q)`s of all alkali metaphosphate glasses, associated with extended-range order. The length scale of extended-range order increases with Me{sup +} size. These phenomena can be explained by the behavior of oxygen atoms. i.e. PO{sub 4} chain-like units ordering around the Me{sup +}.

  4. Estimation of intermediate grade uranium resources. Final report

    International Nuclear Information System (INIS)

    The purpose of this project is to analyze the technique currently used by DOE to estimate intermediate grade uranium (0.01 to 0.05% U3O8) and, if possible, suggest alternatives to improve the accuracy and precision of the estimate. There are three principal conclusions resulting from this study. They relate to the quantity, distribution and sampling of intermediate grade uranium. While the results of this study must be validated further, they indicate that DOE may be underestimating intermediate level reserves by 20 to 30%. Plots of grade of U3O8 versus tonnage of ore and tonnage U3O8 indicate grade-tonnage relationships that are essentially log-linear, at least down to 0.01% U3O8. Though this is not an unexpected finding, it may provide a technique for reducing the uncertainty of intermediate grade endowment. The results of this study indicate that a much lower drill hole density is necessary for DOE to estimate uranium resources than for a mining company to calculate ore resources. Though errors in local estimates will occur, they will tend to cancel over the entire deposit

These partners bare different naming due to their different set of rights and obligations set forth by the law or by the parties, and it is from this that the classification of the intermediation can be set forth. The commercial intermediation represents the activity that one person executes either in the name and on behalf of another person, or using its own name but on behalf of another person, or, finally, using its own name but on behalf of acting towards a common goal with the person who mandated her (the principal, in relation with who it is either a proxy or an independent intermediary, only negotiating or both negotiating and binding the principal. The purpose of the paper is to strictly define and set in order the various variations of the juridical operation that is the commercial intermediation, presented both in the light of the actual legal framework and also by reference to the New Civil Code. Also, the purpose is to highlight and systematize the contractual relationships from which the parties involved in a commercial intermediary operation may choose and the rights and obligations specific to each contract.

  9. Evidence for an intermediate in tau filament formation.

    Science.gov (United States)

    Chirita, Carmen N; Kuret, Jeff

    2004-02-17

    Alzheimer's disease is defined in part by the intraneuronal accumulation of filaments comprised of the microtubule-associated protein tau. In vitro, fibrillization of full-length, unphosphorylated recombinant tau can be induced under near-physiological conditions by treatment with various agents, including anionic surfactants. Here we examine the pathway through which anionic surfactants promote tau fibrillization using a combination of electron microscopy and fluorescence spectroscopy. Protein and surfactant first interacted in solution to form micelles, which then provided negatively charged surfaces that accumulated tau aggregates. Surface aggregation of tau protein was followed by the time-dependent appearance of a thioflavin S reactive intermediate that accumulated over a period of hours. The intermediate was unstable in the absence of anionic surfaces, suggesting it was not filamentous. Fibrillization proceeded after intermediate formation with classic nucleation-dependent kinetics, consisting of lag phase followed by the exponential increase in filament lengths, followed by an equilibrium phase reached in approximately 24 h. The pathway did not require protein insertion into the micelle hydrophobic core or conformational change arising from mixed micelle formation, because anionic microspheres constructed from impermeable polystyrene were capable of qualitatively reproducing all aspects of the fibrillization reaction. It is proposed that the progression from amorphous aggregation through intermediate formation and fibrillization may underlie the activity of other inducers such as hyperphosphorylation and may be operative in vivo.

    Context: Intermediate mass protostars provide a bridge between low- and high-mass protostars. Furthermore, they are an important component of the UV interstellar radiation field. Despite their relevance, little is known about their formation process. Aims: We present a systematic study of the physical structure of five intermediate mass, candidate Class 0 protostars. Our two goals are to shed light on the first phase of intermediate mass star formation and to compare these protostars with low- and high-mass sources. Methods: We derived the dust and gas temperature and density profiles of the sample. We analysed all existing continuum data on each source and modelled the resulting SED with the 1D radiative transfer code DUSTY. The gas temperature was then predicted by means of a modified version of the code CHT96. Results: We found that the density profiles of five out of six studied intermediate mass envelopes are consistent with the predictions of the "inside-out" collapse theory.We compared several physical...

  16. Visual dictionaries as intermediate features in the human brain

    Directory of Open Access Journals (Sweden)

    Kandan eRamakrishnan

    2015-01-01

    Full Text Available The human visual system is assumed to transform low level visual features to object and scene representations via features of intermediate complexity. How the brain computationally represents intermediate features is still unclear. To further elucidate this, we compared the biologically plausible HMAX model and Bag of Words (BoW model from computer vision. Both these computational models use visual dictionaries, candidate features of intermediate complexity, to represent visual scenes, and the models have been proven effective in automatic object and scene recognition. These models however differ in the computation of visual dictionaries and pooling techniques. We investigated where in the brain and to what extent human fMRI responses to short video can be accounted for by multiple hierarchical levels of the HMAX and BoW models. Brain activity of 20 subjects obtained while viewing a short video clip was analyzed voxel-wise using a distance-based variation partitioning method. Results revealed that both HMAX and BoW explain a significant amount of brain activity in early visual regions V1, V2 and V3. However BoW exhibits more consistency across subjects in accounting for brain activity compared to HMAX. Furthermore, visual dictionary representations by HMAX and BoW explain significantly some brain activity in higher areas which are believed to process intermediate features. Overall our results indicate that, although both HMAX and BoW account for activity in the human visual system, the BoW seems to more faithfully represent neural responses in low and intermediate level visual areas of the brain.

  17. Neuroimmune interactions in itch: Do chronic itch, chronic pain, and chronic cough share similar mechanisms?

    Science.gov (United States)

    Ji, Ru-Rong

    2015-12-01

    Itch and pain are closely related but also clearly distinct sensations. Pain is known to suppress itch, while analgesics such as morphine can provoke itch. However, in pathological and chronic conditions, pain and itch also have similarities. Dysfunction of the nervous system, as manifested by neural plastic changes in primary sensory neurons of the peripheral nervous system (peripheral sensitization) and spinal cord and brain stem neurons in the central nervous system (central sensitization) will result in chronic pain and itch. Importantly, these diseases also result from immune dysfunction, since inflammatory mediators can directly activate or sensitize nociceptive and pruriceptive neurons in the peripheral and central nervous system, leading to pain and itch hypersensitivity. In this mini-review, I discuss the roles of Toll-like receptors (TLRs), transient receptor potential ankyrin 1 (TRPA1) ion channel, and Nav1.7 sodium channel in regulating itch and inflammation, with special emphasis of neuronal TLR signaling and the interaction of TLR7 and TRPA1. Chronic pain and chronic itch are debilitating diseases and dramatically impact the life quality of patients. Targeting TLRs for the control of inflammation, neuroinflammation (inflammation restricted in the nervous system), and hyperexcitability of nociceptors and pruriceptors will lead to new therapeutics for the relief of chronic pain and chronic itch. Finally, given the shared mechanisms among chronic cough, chronic pain, and chronic itch and the demonstrated efficacy of the neuropathic pain drug gabapentin in treating chronic cough, novel therapeutics targeting TRPA1, Nav1.7, and TLRs may also help to alleviate refractory cough via modulating neuron-immune interaction.

    INTRODUCTION. Patients with chronic migraine often report lower cognitive performance, which affects their quality of life. AIMS. To analyse whether the mnemonic capacity of patients with chronic migraine is altered or not. SUBJECTS AND METHODS. A cross-sectional study was conducted in patients with chronic migraine evaluated consecutively in our unit, and paired by age (18-60 years) and gender with a control group consisting of cognitively healthy volunteers. The following cognitive instruments were administered: Folstein Minimental State Examination (MMSE), Memory Alteration Test (M@T), Montreal Cognitive Assessment (MoCA) and working memory. RESULTS. A total of 30 patients with chronic migraine were included (mean age: 49.33 ± 10.05 years) paired with a control group of 30 healthy volunteers (mean age: 44.83 ± 10.91 years). The mean elapsed time since onset of the patients with chronic migraine was 4.47 ± 2.74 years. On performing a comparative analysis between the two groups, significant differences were found with overall lower scores in the group of patients with chronic migraine in the MoCA (24.16 versus 29), M@T (43.76 versus 48.8) and working memory tests (17.5 versus 24.26). Performance in the MMSE was similar in both groups. CONCLUSIONS. Patients with chronic migraine can have lower cognitive performance regardless of distracting elements, such as pharmacological factors or psychiatric comorbidity, since chronic migraine can be understood as yet another element within the spectrum of chronic pain.

  19. Common Questions About Chronic Prostatitis.

    2016-02-15

    Chronic prostatitis is relatively common, with a lifetime prevalence of 1.8% to 8.2%. Risk factors include conditions that facilitate introduction of bacteria into the urethra and prostate (which also predispose the patient to urinary tract infections) and conditions that can lead to chronic neuropathic pain. Chronic prostatitis must be differentiated from other causes of chronic pelvic pain, such as interstitial cystitis/bladder pain syndrome and pelvic floor dysfunction; prostate and bladder cancers; benign prostatic hyperplasia; urolithiasis; and other causes of dysuria, urinary frequency, and nocturia. The National Institutes of Health divides prostatitis into four syndromes: acute bacterial prostatitis, chronic bacterial prostatitis (CBP), chronic nonbacterial prostatitis (CNP)/chronic pelvic pain syndrome (CPPS), and asymptomatic inflammatory prostatitis. CBP and CNP/CPPS both lead to pelvic pain and lower urinary tract symptoms. CBP presents as recurrent urinary tract infections with the same organism identified on repeated cultures; it responds to a prolonged course of an antibiotic that adequately penetrates the prostate, if the urine culture suggests sensitivity. If four to six weeks of antibiotic therapy is effective but symptoms recur, another course may be prescribed, perhaps in combination with alpha blockers or nonopioid analgesics. CNP/CPPS, accounting for more than 90% of chronic prostatitis cases, presents as prostatic pain lasting at least three months without consistent culture results. Weak evidence supports the use of alpha blockers, pain medications, and a four- to six-week course of antibiotics for the treatment of CNP/CPPS. Patients may also be referred to a psychologist experienced in managing chronic pain. Experts on this condition recommend a combination of treatments tailored to the patient's phenotypic presentation. Urology referral should be considered when appropriate treatment is ineffective. Additional treatments include pelvic

  20. A nuclear proliferation antigen in chronic lymphoproliferative disease

    International Nuclear Information System (INIS)

    To determine whether the proliferation rates of tumour cells, in chronic lymphoproliferative disorders may reflect disease activity and relate to prognosis, we studied the expression of Ki-67% (a nuclear proliferation marker) by alkaline phosphatase anti-alkaline phosphatase technique (APAAP), in peripheral blood and bone marrow mononuclear cells (separated on ficoll-hypaque) and in lymph-node biopsies, from patients with chronic lymphatic leukemia (Cll), chronic lymphatic leukemia/prolymphocytic leukemia (CLL/PLL), prolymphocytic leukemia (PLL) and non-hodgkin's lymphoma with leukemic plase. The proliferation rate was determined for these patients at presentation and again two months after therapy (to detect any change with therapy). We found that the highest rate of proliferation in each group was parallel to the degree of malignancy i.e. PLL showed higher proliferation than CLL/PLL, and CLL/PLL showed higher proliferation than CLL. In the NHL group the highest proliferation rate was found in the high high-grade NHL, followed by intermediate grade NHL then the low grade NHL. Lymph node biopsies also showed the same relation between proliferation rates and degree of malignancy. Bone marrow cells did not show a particular pattern probably due to interference from the erythroid element and contamination by peripheral blood. Ki-67% was compared to other proliferation markers serum B2 microglobulin and lactate dehydrogenase. It was found to be an independent marker of proliferation it is unaffected by hepatic, renal and gastrointestinal elements and thus its specificity for the tumour proliferation

    Chronic thromboembolic pulmonary hypertension (CTEPH) is one of the leading causes of severe pulmonary hypertension. According to previously reported studies in the pertinent literature, chronic inflammatory conditions may be implicated in the development of CTEPH. We herein describe the case of a 56-year-old woman who was diagnosed with CTEPH in association with chronic infection. The patient had experienced five episodes of pneumonia in the five years prior to the diagnosis of CTEPH. Blood tests from the previous five years of outpatient follow-up demonstrated that the C-reactive protein level was slightly elevated. This case suggests that a relationship exists between chronic inflammation and CTEPH, and furthermore, may contribute towards elucidating the pathophysiology of CTEPH. PMID:27250055

    Chronic paronychia is a common occupational disease. It is multifactorial and affects a number of different groups of workers. However, the condition is not described as affecting hairdressers although hairdressing is associated with a range of other occupation-related hand conditions. We report an unusual case of chronic paronychia in a female hairdresser which occurred as a consequence of a hair shaft penetrating beneath the nail fold. Personal hygiene with thorough removal of any hairs that have penetrated the epidermis and wearing clean gloves can prevent the condition. We suggest that clinicians should be aware of the types of occupation and mechanisms involved in patients developing chronic paronychia. PMID:24985481

    Most sinus infections are viral and only a small percentage develop bacterial infection. Rhino-, influenza, and para-influenza viruses are the most frequent viral causes of sinusitis. The most common bacterial isolates from children and adult patients with community-acquired acute bacterial sinusitis are Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pyogenes. Staphylococcus aureus and anaerobic organisms (Prevotella and Porphyromonas, Fusobacterium, and Peptostreptococcus spp.) are the commonest isolates in chronic rhinosinusitis (CRS). Aerobic and anaerobic beta lactamase-producing bacteria (BLPB) were recovered from over a third of these patients. Methicillin-resistant S. aureus (MRSA) accounted for over 60 % of S. aureus isolates. Pseudomonas aeruginosa and other aerobic and facultative Gram-negative rods are frequently recovered in nosocomial sinusitis, the immunocompromised host, individuals with human immunodeficiency virus infection, and in cystic fibrosis. The CRS infection evolves the formation of a biofilm that might play a significant role in the pathogenesis and persistence of CRS. The microbiology of sinusitis is influenced by previous antimicrobial therapy, vaccinations, and the presence of normal flora capable of interfering with the growth of pathogens. Recognition of the unique microbiology of CRS and their antimicrobial susceptibility is of great importance when selecting antimicrobial therapy. PMID:27086363

    Currently, several novel drugs are available for chronic lymphocytic leukemia (CLL) in Western countries. Of these drugs, those that inhibit the B-cell receptor (BCR) signaling pathway are the most promising. Ibrutinib inhibits BTK in the BCR pathway and can be administered orally. The results of several clinical trials suggest that ibrutinib is highly effective against relapsed/resistant (RR) and treatment-naïve CLL. Furthermore, ibrutinib shows equivalent efficacy on CLL with the 17p deletion. Idelalisib, which also blocks the BCR pathway, inhibits PIK3delta and induces CLL cell death. Clinical trials have shown outstanding efficacy of idelalisib against RR-CLL, especially when administered with antiCD20 antibodies. This drug is also effective against CLL with the 17p deletion. ABT-199 is another novel drug; it inhibits BCL2 signaling, not the BCR pathway, and can be administered orally. The efficacy of ABT-199 against RR-CLL has been demonstrated in a number of clinical trials. These drugs have only mild toxicity and can be used for patients in poor general condition. Unfortunately, none of these drugs have yet been approved in Japan. Rapid resolution of the 'drug lag' problem is necessary. PMID:27076234

    Chronic urticaria is defined as episodic or daily hives lasting for at least 6 weeks and impairs quality of life. Two main subtypes include chronic idiopathic (spontaneous) urticaria and inducible (physical) urticaria, but some patients have urticarial vasculitis. "Autoimmune chronic urticaria" implies the presence of histamine releasing or mast cell activating autoantibodies to IgE or FcϵRI, the high affinity receptor on mast cells and basophils. In patients not readily controlled with labeled dosages of second generation H1 receptor antagonists (antihistamines), there is evidence for reduction of urticaria using up to 4 fold increases in labeled dosages. The biologic modifier, omalizumab, helps to reduce lesions of chronic urticaria within 1-2 weeks. PMID:25383135

    Chronic musculoskeletal pain results from a complex interplay of mechanical, biochemical, psychological, and social factors. Effective management is markedly different from that of acute musculoskeletal pain. Understanding the physiology of pain transmission, modulation, and perception is crucial for effective management. Pharmacologic and nonpharmacologic therapies such as psychotherapy and biofeedback exercises can be used to manage chronic pain. Evidence-based treatment recommendations have been made for chronic pain conditions frequently encountered by orthopaedic surgeons, including low back, osteoarthritic, posttraumatic, and neuropathic pain. Extended-release tramadol; select tricyclic antidepressants, serotonin reuptake inhibitors, and anticonvulsants; and topical medications such as lidocaine, diclofenac, and capsaicin are among the most effective treatments. However, drug efficacy varies significantly by indication. Orthopaedic surgeons should be familiar with the widely available safe and effective nonnarcotic options for chronic musculoskeletal pain.

    Hague, Matthew; Shenker, Nicholas

    2014-12-01

    Chronic pain is defined as an unpleasant sensory and emotional experience persisting longer than the normal process of healing, usually longer than 3 months. About a fifth of the world's population is believed to suffer from chronic pain. In Europe, chronic pain accounts for nearly 500 m lost working days, and it costs the European economy >€34 billion (£28 billion) every year. Establishing a reliable diagnosis is the primary challenge in evaluating a patient with chronic pain. Common diagnoses not to miss include seronegative spondyloarthritides, endocrine abnormalities including severe vitamin D deficiency and polymyalgia rheumatica. Once important or treatable diagnoses have been ruled out, the history can be used as a tool to establish a therapeutic plan for shared decision-making using the biopsychosocial model. Onward referral to pain clinics can be helpful for more involved patient management, but often good outcomes are achieved with the support of primary care. PMID:26096090

    Therapeutic vaccines aim to prevent severe complications of a chronic infection by reinforcing host defenses when some immune control, albeit insufficient, can already be demonstrated and when a conventional antimicrobial therapy either is not available or has limited efficacy. We focus on the rationale and challenges behind this still controversial strategy and provide examples from three major chronic infectious diseases-human immunodeficiency virus, hepatitis B virus, and human papillomavirus-for which the efficacy of therapeutic vaccines is currently being evaluated.
