    The glucocorticoid dexamethasone in a bolus dose of 8-10 mg followed by quarterly dose of 4 mg is commonly used during intracranial surgery so as to reduce oedema and vascular permeability. However, the detrimental hyperglycaemic effects of dexamethasone may override its potentially beneficial effects. The present prospective, randomised study aimed at comparing the degree and magnitude of hyperglycaemia induced by prophylactic administration of dexamethasone in patients undergoing elective craniotomy. Sixty American Society of Anaesthesiologist (ASA) grade-I and II patients were randomly assigned to three groups of 20 patients each. Group-I received dexamethasone during surgery for the first time. Group-II received dexamethasone in addition to receiving it pre-operatively, whereas Group-III (control group) patients were administered normal saline as placebo. Baseline blood glucose (BG) was measured in all the three groups before induction of anaesthesia and thereafter after every hour for 4 h and then two-hourly. Besides intra- and intergroup comparison of BG, peak BG concentration was also recorded for each patient. Statistical analysis was carried out with analysis of variance (ANOVA) and Student's t-test and value of P < 0.05 was considered statistically significant. Baseline BG reading were higher and statistically significant in Group-II as compared with Group-I and Group-III (P < 0.05). However, peak BG levels were significantly higher in Group-I than in Group-II and III (P < 0.05). Similarly, the magnitude of change in peak BG was significantly higher in Group-I as compared to Group-II and III (P < 0.05). Peri-operative administration of dexamethasone during neurosurgical procedures can cause significant increase in BG concentration especially in patients who receive dexamethasone intra-operatively only.

    Full Text Available The development of new adjuvants enables fine modulation of the elicited immune responses. Ideally, the use of one or more adjuvants should result in the induction of a protective immune response against the specific pathogen. We have evaluated the immune response and protection against Trypanosoma cruzi infection in mice vaccinated with recombinant Tc52 or its N- and C-terminal domains (NTc52 and CTc52 adjuvanted either with the STING (Stimulator of Interferon Genes agonist cyclic di-AMP (c-di-AMP, a pegylated derivative of α-galactosylceramide (αGC-PEG, or oligodeoxynucleotides containing unmethylated CpG motifs (ODN-CpG. All groups immunized with the recombinant proteins plus adjuvant: Tc52+c-di-AMP, NTc52+c-di-AMP, CTc52+c-di-AMP, NTc52+c-di-AMP+αGC-PEG, NTc52+CpG, developed significantly higher anti-Tc52 IgG titers than controls. Groups immunized with c-di-AMP and Tc52, NTc52 or CTc52 showed the highest Tc52-specific IgA titers in nasal lavages. All groups immunized with the recombinant proteins plus adjuvant developed a strong specific cellular immune response in splenocytes and lymph node cells with significant differences for groups immunized with c-di-AMP and Tc52, NTc52 or CTc52. These groups also showed high levels of Tc52-specific IL-17 and IFN-γ producing cells, while NTc52+CpG group only showed significant difference with control in IFN-γ producing cells. Groups immunized with c-di-AMP and Tc52, NTc52 or CTc52 developed predominantly a Th17 and Th1immune response, whereas for NTc52+CpG it was a dominant Th1 response. It was previously described that αGC-PEG inhibits Th17 differentiation by activating NKT cells. Thus, in this work we have also included a group immunized with both adjuvants (NTc52+c-di-AMP+αGC-PEG with the aim to modulate the Th17 response induced by c-di-AMP. This group showed a significant reduction in the number of Tc52-specific IL-17 producing splenocytes, as compared to the group NTc52+c-di-AMP, which has

    To examine whether the near-infrared spectroscopy combined with vascular occlusion test technique could detect differences in vascular responsiveness during hyperglycaemia between normal-weight individuals and individuals with obesity. A total of 16 normal-weight individuals (body mass index, 21.3 ± 1.7 kg/m 2 ) and 13 individuals with obesity (body mass index, 34.4 ± 2.0 kg/m 2 ) were submitted to five vascular occlusion tests (Pre, 30, 60, 90 and 120 min after glucose challenge). Vascular responsiveness was determined by the Slope 2 (Slope 2 StO 2 ) and the area under the curve (StO 2AUC ) of oxygen saturation derived from near-infrared spectroscopy-vascular occlusion test. The Slope 2 StO 2 increased from 1.07 ± 0.16%/s (Pre) to 1.53 ± 0.21%/s at 90 min ( p obese it increased from 0.71 ± 0.09%/s (Pre) to 0.92 ± 0.14%/s at 60 min ( p obesity. Near-infrared spectroscopy-vascular occlusion test technique was capable of detecting differences in vascular responsiveness during hyperglycaemia between normal-weight individuals and individuals with obesity.

  5. Timing is critical for effective glucocorticoid receptor mediated repression of the cAMP-induced CRH gene.

    Full Text Available Glucocorticoid negative feedback of the hypothalamus-pituitary-adrenal axis is mediated in part by direct repression of gene transcription in glucocorticoid receptor (GR expressing cells. We have investigated the cross talk between the two main signaling pathways involved in activation and repression of corticotrophin releasing hormone (CRH mRNA expression: cyclic AMP (cAMP and GR. We report that in the At-T20 cell-line the glucocorticoid-mediated repression of the cAMP-induced human CRH proximal promoter activity depends on the relative timing of activation of both signaling pathways. Activation of the GR prior to or in conjunction with cAMP signaling results in an effective repression of the cAMP-induced transcription of the CRH gene. In contrast, activation of the GR 10 minutes after onset of cAMP treatment, results in a significant loss of GR-mediated repression. In addition, translocation of ligand-activated GR to the nucleus was found as early as 10 minutes after glucocorticoid treatment. Interestingly, while both signaling cascades counteract each other on the CRH proximal promoter, they synergize on a synthetic promoter containing 'positive' response elements. Since the order of activation of both signaling pathways may vary considerably in vivo, we conclude that a critical time-window exists for effective repression of the CRH gene by glucocorticoids.

    Highlights: ► cAMP-induced c-fos expression in hippocampal neurons requires a submembraneous Ca 2+ pool. ► The submembraneous Ca 2+ pool derives from intracellular ER stores. ► Expression of IP 3 -metabolizing enzymes inhibits cAMP-induced c-fos expression. ► SRE-mediated and CRE-mediated gene expression is sensitive to IP 3 -metabolizing enzymes. ► Intracellular Ca 2+ release is required for cAMP-induced nuclear translocation of TORC1. -- Abstract: Ca 2+ and cAMP are widely used in concert by neurons to relay signals from the synapse to the nucleus, where synaptic activity modulates gene expression required for synaptic plasticity. Neurons utilize different transcriptional regulators to integrate information encoded in the spatiotemporal dynamics and magnitude of Ca 2+ and cAMP signals, including some that are Ca 2+ -responsive, some that are cAMP-responsive and some that detect coincident Ca 2+ and cAMP signals. Because Ca 2+ and cAMP can influence each other’s amplitude and spatiotemporal characteristics, we investigated how cAMP acts to regulate gene expression when increases in intracellular Ca 2+ are buffered. We show here that cAMP-mobilizing stimuli are unable to induce expression of the immediate early gene c-fos in hippocampal neurons in the presence of the intracellular Ca 2+ buffer BAPTA-AM. Expression of enzymes that attenuate intracellular IP 3 levels also inhibited cAMP-dependent c-fos induction. Synaptic activity induces c-fos transcription through two cis regulatory DNA elements – the CRE and the SRE. We show here that in response to cAMP both CRE-mediated and SRE-mediated induction of a luciferase reporter gene is attenuated by IP 3 metabolizing enzymes. Furthermore, cAMP-induced nuclear translocation of the CREB coactivator TORC1 was inhibited by depletion of intracellular Ca 2+ stores. Our data indicate that Ca 2+ release from IP 3 -sensitive pools is required for cAMP-induced transcription in hippocampal neurons.

    Abstract Objective: No information is available on the effect of cigarette smoke on bronchoconstrictor-induced air trapping in asthma. The aim of this study was to evaluate the additional influence of smoking on methacholine- and adenosine 5'-monophosphate (AMP)-induced air trapping in subjects with asthma. Airway responsiveness to methacholine and AMP, bronchial (J'awNO) and alveolar (CANO) nitric oxide (NO) and exhaled breath condensate pH were measured in 68 adults (23 current smokers with asthma, 23 non-smokers with asthma and 22 current or former smokers with chronic obstructive pulmonary disease; COPD). The degree of air trapping induced by each bronchoconstrictor agent was expressed by the percent fall in forced vital capacity (FVC) at a 20% fall in forced expiratory volume in 1 s relative to FVC after saline inhalation (ΔFVC%). The ΔFVC% for AMP was higher in both smokers with asthma and patients with COPD than in non-smokers with asthma (p<0.001). By contrast, ΔFVC% for methacholine was similar in the three groups of subjects (p=0.69). In smokers with asthma, but not in the other two groups, there was a correlation between the residual volume/total lung capacity at baseline and the ΔFVC% induced by each bronchoconstrictor agent. Mean values for J'awNO were higher in non-smokers with asthma than in the other two groups (p<0.05). The results of this study suggest that factors underlying bronchoconstriction induced by indirect agonists are different in smokers and non-smokers with asthma. These observations might be clinically relevant, because triggers that frequently induce bronchial obstruction in the real world act by an indirect mechanism.

    To describe the frequencies, presenting characteristics (demographic, clinical and biochemical) and outcomes (duration of admission and mortality rates) for various types of hyperglycaemic crisis. Retrospective review of medical records of patients with hyperglycaemic crisis admitted to Nelson Mandela Academic Hospital, Mthatha, E Cape, from 1 January 2008 to 31 December 2009. Outcome measures were duration of admission and mortality. Data were available for 269 admissions (response rate 81.0%), 169 females and 100 males. Admissions for hyperglycaemia (HG, N=119), and non-hyperosmolar diabetic ketoacidosis (NHDKA, N=97) were more frequent than those for hyperosmolar hyperglycaemic state (HHS, N=29) and hyperosmolar diabetic ketoacidosis (HDKA, N=24). Duration of admission was similar in all groups. Mortality was high in all groups, but was higher in patients with HDKA (37.5%, risk ratio (RR) 3.88, 95% confidence interval (CI) 1.41 - 10.67, p=0.009), HHS (31.0%, RR 2.91, 95% CI 1.09 - 7.75, p=0.033) and HG (19.5%, RR 1.56, 95% CI 0.75 - 3.21, p=0.236) than in those with NHDKA (13.4%). HDKA (62.5%) was associated with new-onset diabetes more often than NHDKA (27.8%), HHS (44.8%) or HG (17.6%) (p<0.0001). An altered level of consciousness was more frequent in HDKA than NHDKA admissions (RR 5.71, 95% CI 1.90 - 17.17, p=0.002). Duration of hospital stay was similar across groups. Mortality rates were high in all groups. New-onset diabetes, altered level of consciousness and mortality were more characteristically associated with HDKA than any of the other types of hyperglycaemic crisis. Optimal glycaemic control in known diabetic patients will reduce rates of hyperglycaemic crisis admissions.

    Diabetes is a metabolic disorder associated with either improper functioning of the beta-cells or wherein cells fail to use insulin properly. Insulin, the principal hormone regulates uptake of glucose from the blood into most of the cells except central nervous system. Therefore, deficiency of insulin or the insensitivity of its receptors plays a key role in all forms of diabetes. In the present work, attempt has been made to find out plant sources which show anti hyperglycaemic activity (AhG) (i.e. compounds that bring down the blood glucose level in the body). Ayurvedic plants showing AhG activity formed the basis of our study by using the platform of Computer Aided Drug Designing (CADD). Among 600 plants showing AhG activity, 500 compounds were selected and screened, out of which 243 compounds showed drug likeness property that can be used as therapeutic ligand/drug. Initial screening of such compounds was done based on their drug likeness or biochemical properties. Dynamic interaction of these molecules was captured through Protein-Ligand study. It also gave an insight of the binding pockets involved. Bench marking of all the parameters were done using the diabetic inhibitor drug, Glipizide. Pharmacokinetic studies of the compounds such as Aloins, Capparisine, Funiculosin and Rhein exhibited less toxicity on various levels of the body. As a conclusion these ligands can lay a foundation for a better anti-diabetic therapy. AhG - Anti hyperglycaemic, CADD - Computer Aided Drug Designing.

    Full Text Available Abstract Background We have previously shown that Matrix metalloproteinase (MMP -2 is a key-enzyme in early trophoblast invasion and that Protein Kinase A (PKA increases MMP-2 expression and trophoblast invasion. The aim of this study was to examine MMP -2 regulation by PKA in invasive trophoblasts: JAR choriocarcinoma cell-line and 6-8 w first trimester trophoblasts. Methods The effect of Forskolin (PKA on MMP-2 expression was assessed by Northern Blot and RT-PCR. Possible transcription factors binding to consensus MMP-2 promoter sequences in response to Forskolin, were detected by EMSA binding assay and their expression assessed by western blot analysis. Antisense transfection of relevant transcription factors was performed and the inhibitory effect assessed on MMP-2 expression (RT-PCR, secretion (zymography and trophoblast invasiveness (transwell migration assay. Results We found that Forskolin increased MMP-2 mRNA in JAR cells within 24 hours, and induced binding to p53, Ets, C/EBP and AP-2. Transcription factors Ets-2, phospho- p53, C/EBP epsilon, C/EBP lambda and AP-2 alpha bound to their respective binding sequences in response to Forskolin and the expressions of these transcription factors were all elevated in Forskolin- treated cells. Inhibition of Ets-2 and p53 reduced MMP-2 expression, secretion and invasiveness of Forskolin treated cells. Conclusion MMP-2 is regulated by PKA through several binding sites and transcription factors including Ets-2, p53, C/EBP, C/EBP lambda and AP-2 alpha. Ets-2 and p53 mediate cAMP- induced trophoblast invasiveness, through regulation of MMP-2.

    This study aimed to report a rare case of hypopituitarism complicated with hyperosmolar hyperglycaemic state and rhabdomyolysis. Hypopituitarism is a clinical syndrome in which there is a deficiency in hormone production by the pituitary gland. It often leads to hypoglycaemia, but in this case the patient was complicated with hyperosmolar hyperglycaemic state. The patient received prompt medical treatment, which effectively prevented the occurrence of possible acute kidney failure and other complications. This is a complicated and rare case. Our report provides some indications for the timely diagnosis and the standardised treatments for a patient who has hypopituitarism complicated with hyperosmolar hyperglycaemic state and rhabdomyolysis. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available The combination of hyperosmolar hyperglycaemic state and central diabetes insipidus is unusual and poses unique diagnostic and therapeutic challenges for clinicians. In a patient with diabetes mellitus presenting with polyuria and polydipsia, poor glycaemic control is usually the first aetiology that is considered, and achieving glycaemic control remains the first course of action. However, severe hypernatraemia, hyperglycaemia and discordance between urine-specific gravity and urine osmolality suggest concurrent symptomatic diabetes insipidus. We report a rare case of concurrent manifestation of hyperosmolar hyperglycaemic state and central diabetes insipidus in a patient with a history of craniopharyngioma.

    To study the dynamics and mechanisms controlling activation of the heterotrimeric G protein Gα2βγ in Dictyostelium in response to stimulation by the chemoattractant cyclic AMP (cAMP), we monitored the G protein subunit interaction in live cells using bioluminescence resonance energy transfer (BRET). We found that cAMP induces the cAR1-mediated dissociation of the G protein subunits to a similar extent in both undifferentiated and differentiated cells, suggesting that only a small number of cAR1 (as expressed in undifferentiated cells) is necessary to induce the full activation of Gα2βγ. In addition, we found that treating cells with caffeine increases the potency of cAMP-induced Gα2βγ activation; and that disrupting the microtubule network but not F-actin inhibits the cAMP-induced dissociation of Gα2βγ. Thus, microtubules are necessary for efficient cAR1-mediated activation of the heterotrimeric G protein. Finally, kinetics analyses of Gα2βγ subunit dissociation induced by different cAMP concentrations indicate that there are two distinct rates at which the heterotrimeric G protein subunits dissociate when cells are stimulated with cAMP concentrations above 500 nM versus only one rate at lower cAMP concentrations. Quantitative modeling suggests that the kinetics profile of Gα2βγ subunit dissociation results from the presence of both uncoupled and G protein pre-coupled cAR1 that have differential affinities for cAMP and, consequently, induce G protein subunit dissociation through different rates. We suggest that these different signaling kinetic profiles may play an important role in initial chemoattractant gradient sensing. Copyright © 2018 Elsevier Inc. All rights reserved.

  14. Roles of crustacean hyperglycaemic hormone in ionic and metabolic homeostasis in the Christmas Island blue crab, Discoplax celeste.

    There is a growing body of evidence implicating the involvement of crustacean hyperglycaemic hormone (CHH) in ionic homeostasis in decapod crustaceans. However, little is known regarding hormonally influenced osmoregulatory processes in terrestrial decapods. As many terrestrial decapods experience opposing seasonal demands upon ionoregulatory physiologies, we reasoned that these would make interesting models in which to study the effect of CHH upon these phenomena. In particular, those (tropical) species that also undergo seasonal migrations might be especially informative, as we know relatively little regarding the nature of CHHs in terrestrial decapods, and hormonally mediated responses to seasonal changes in metabolic demands might also be superimposed or otherwise integrated with those associated with ionic homeostasis. Using Discoplax celeste as a model crab that experiences seasonal extremes in water availability, and exhibits diurnal and migratory activity patterns, we identified two CHHs in the sinus gland. We biochemically characterised (cDNA cloning) one CHH and functionally characterised (in terms of dose-dependent hyperglycaemic responses and glucose-dependent negative feedback loops) both CHHs. Whole-animal in situ branchial chamber (22)NaCl perfusion experiments showed that injection of both CHHs increased gill Na(+) uptake in a seasonally dependent manner, and (51)Cr-EDTA clearance experiments demonstrated that CHH increased urine production by the antennal gland. Seasonal and salinity-dependent differences in haemolymph CHH titre further implicated CHH in osmoregulatory processes. Intriguingly, CHH appeared to have no effect on gill Na(+)/K(+)-ATPase or V-ATPase activity, suggesting unknown mechanisms of this hormone's action on Na(+) transport across gill epithelia.

    Dibutyryl cyclic AMP (dbcAMP) and retinoic acid (RA) have been demonstrated to be the inducers of morphological differentiation in SH-SY5Y cells, a human catecholaminergic neuroblastoma cell line. However, it remains unclear whether morphologically differentiated SH-SY5Y cells by these compounds acquire catecholaminergic properties. We focused on the alteration of tyrosine hydroxylase (TH) expression and intracellular content of noradrenaline (NA) as the indicators of functional differentiation. Three days treatment with dbcAMP (1mM) and RA (10microM) induced morphological changes and an increase of TH-positive cells using immunocytochemical analysis in SH-SY5Y cells. The percentage of TH-expressing cells in dbcAMP (1mM) treatment was larger than that in RA (10microM) treatment. In addition, dbcAMP increased intracellular NA content, whereas RA did not. The dbcAMP-induced increase in TH-expressing cells is partially inhibited by KT5720, a protein kinase A (PKA) inhibitor. We also investigated the effect of butyrate on SH-SY5Y cells, because dbcAMP is enzymatically degraded by intracellular esterase, thereby resulting in the formation of butyrate. Butyrate induced the increase of NA content at lower concentrations than dbcAMP, although the increase in TH-expressing cells by butyrate was smaller than that by dbcAMP. The dbcAMP (1mM)- and butyrate (0.3mM)-induced increase in NA content was completely suppressed by alpha-methyl-p-tyrosine (1mM), an inhibitor of TH. These results suggest that dbcAMP induces differentiation into the noradrenergic phenotype through both PKA activation and butyrate.

    Alveolar macrophages play significant roles in the pathogenesis of several inflammatory lung diseases. Increases in exhaled nitric oxide (NO) are well documented to reflect disease severity in the airway. In this study, we investigated the effect of 3-(5′-hydroxymethyl-2′-furyl)-1-benzyl indazole (YC-1), a known activator of soluble guanylyl cyclase, on prostaglandin (PG)E{sub 1} (a stable PGE{sub 2} analogue) and forskolin (a adenylate cyclase activator) induced NO production and inducible NO synthase (iNOS) expression in rat alveolar macrophages (NR8383). YC-1 did not directly cause NO production or iNOS expression, but drastically potentiated PGE{sub 1}- or forskolin-induced NO production and iNOS expression in NR8383 alveolar macrophages. Combination treatment with YC-1 and PGE{sub 1} significantly increased phosphorylation of the cAMP response element-binding protein (CREB), but not nuclear factor (NF)-κB activation. The combined effect on NO production, iNOS expression, and CREB phosphorylation was reversed by a protein kinase (PK)A inhibitor (H89), suggesting that the potentiating functions were mediated through a cAMP/PKA signaling pathway. Consistent with this, cAMP analogues, but not the cGMP analogue, caused NO release, iNOS expression, and CREB activation. YC-1 treatment induced an increase in PGE{sub 1}-induced cAMP formation, which occurred through the inhibition of cAMP-specific phosphodiesterase (PDE) activity. Furthermore, the combination of rolipram (an inhibitor of PDE4), but not milronone (an inhibitor of PDE3), and PGE{sub 1} also triggered NO production and iNOS expression. In summary, YC-1 potentiates PGE{sub 1}-induced NO production and iNOS expression in alveolar macrophages through inhibition of cAMP PDE activity and activation of the cAMP/PKA/CREB signaling pathway. Highlights: ► YC-1 potentiated PGE1-induced iNOS expression in alveolar macrophages. ► The combination of YC-1 and PGE1 increased CREB but not NFκB activation.

    Few studies have investigated regional variation in medication-taking behaviour. The purpose of this study was to investigate whether there are regional differences in non-persistence and non-adherence to oral anti-hyperglycaemic agents in patients initiating therapy and examine if any association exists between different types of comorbidity in terms of medication-taking behaviour.\\r\

    It is unclear whether ketosis-prone diabetes is a specific type or a subtype of Type 2 diabetes. We aimed to describe the clinical and metabolic features of ketosis-prone diabetes in a sub-Saharan population. We consecutively enrolled and characterized 173 people with non-autoimmune diabetes admitted for hyperglycaemic crisis at the Yaoundé Central Hospital, Cameroon. Blood samples were collected for fasting glucose, HbA 1c , lipid profile and C-peptide assays with insulin resistance and secretion estimation by homeostasis model assessment. People were classified as having Type 2 diabetes (n = 124) or ketosis-prone diabetes (n = 49). Ketosis-prone diabetes was sub-classified as new-onset ketotic phase (n = 34) or non-ketotic phase (n = 15). Ketosis-prone diabetes was found in 28.3% of the hyperglycaemic crises. Age at diabetes diagnosis was comparable in Type 2 and ketosis-prone diabetes [48 ± 14 vs 47 ± 11 years; P = 0.13] with a similar sex distribution. Overall BMI was 27.7 ± 13.4 kg/m 2 and was ≥ 25 kg/m 2 in 55.8% of those taking part, however, 73.5% of those with ketosis-prone diabetes reported weight loss of > 5% at diagnosis. Blood pressure and lipid profile were comparable in both types. Ketosis-prone diabetes in the ketotic phase was characterized by lower insulin secretion and higher serum triglycerides compared with non-ketotic ketosis prone and Type 2 diabetes. Type 2 and ketosis prone diabetes in the non-ketotic phase were comparable in terms of lipid profile, blood pressure, waist-to-hip ratio, BMI and fat mass, insulin secretion and insulin resistance indices. Ketosis-prone diabetes is likely to be a subtype of Type 2 diabetes with the potential to develop acute insulinopenic episodes. © 2016 Diabetes UK.

    Cyclic AMP plays a pivotal role in neurite growth. During outgrowth, a trafficking system supplies membrane at growth cones. However, the cAMP-induced signaling leading to the regulation of membrane trafficking remains unknown. TC10 is a Rho family GTPase that is essential for specific types of vesicular trafficking. Recent studies have shown a role of TC10 in neurite growth in NGF-treated PC12 cells. Here, we investigated a mechanical linkage between cAMP and TC10 in neuritogenesis. Plasmalemmal TC10 activity decreased abruptly after cAMP addition in neuronal cells. TC10 was locally inactivated at extending neurite tips in cAMP-treated PC12 cells. TC10 depletion led to a decrease in cAMP-induced neurite outgrowth. Constitutively active TC10 could not rescue this growth reduction, supporting our model for a role of GTP hydrolysis of TC10 in neuritogenesis by accelerating vesicle fusion. The cAMP-induced TC10 inactivation was mediated by PKA. Considering cAMP-induced RhoA inactivation, we found that p190B, but not p190A, mediated inactivation of TC10 and RhoA. Upon cAMP treatment, p190B was recruited to the plasma membrane. STEF depletion and Rac1-N17 expression reduced cAMP-induced TC10 inactivation. Together, the PKA-STEF-Rac1-p190B pathway leading to inactivation of TC10 and RhoA at the plasma membrane plays an important role in cAMP-induced neurite outgrowth. © 2017 Molecular Biology Society of Japan and John Wiley & Sons Australia, Ltd.

    The anti-hyperglycaemic effects of the leaves of Acer pycnanthum K. Koch, and the purification and identification of the active compounds were investigated. Extracts of the leaves showed a potent inhibitory effect on the α-glucosidase in both in vivo and in vitro experiments. The fractionation of the crude extract gave two active compounds, ginnalin B (6-O-galloyl-1,5-anhydro-D-glucitol) and ginnalin C (2-O-galloyl-1,5-anhydro-D-glucitol), by spectroscopic analysis. This is the first report that A. pycnanthum and its constituents may be useful for the prevention or treatment of diabetes mellitus.

    There is large interindividual variability in serum teicoplanin (TEIC) concentrations after administration of a loading dose, and the factors that influence the pharmacokinetics of TEIC are disputed. The aim of this study was to clarify changes in the pharmacokinetics of TEIC that occur in patients with hyperglycaemia as well as the impact of albumin glycosylation on the pharmacokinetics of TEIC. This study consisted of retrospective and prospective investigations. The pharmacokinetic parameters of TEIC were retrospectively compared between patients receiving TEIC treatment. Ninety-four patients were divided into four groups according to their serum albumin and blood glucose concentrations [(i) hyperglycaemic hypoalbuminaemia (albuminalbumin≥3.0g/dL) (n=9); and (iv) non-hyperglycaemic normoalbuminaemia (n=40)]. In addition, the concentration of glycosylated albumin was prospectively determined in 28 patients. At 12h after administration of a loading dose, patients with hyperglycaemic hypoalbuminaemia displayed significantly lower serum TEIC concentrations (Palbumin was significantly correlated with the association constant (Ka) of TEIC for albumin (r=0.53, P=0.004) and the Vd (r=0.41, P=0.031). These results suggest that hyperglycaemic hypoalbuminaemia lowers the serum TEIC concentration, which is attributable to the decreased Ka and increased Vd of TEIC by albumin glycosylation.

    Full Text Available The antidiabetic potentials of Heliotropium indicum L. leaf aqueous (HILA extract used for the management of diabetes by Traditional Medicinal Practitioners (TMPs in Nigeria was assessed. Alloxan (ALX-induced hyperglycaemic rats were orally administered with known folkloric dosage of 30 and 75 mg/kg b. wt. of HILA extract, once a day, for 14 days. Fasting blood glucose (FBG levels were monitored and pancreatic histology was examined. Net hepatic glycogen (GLY concentration and lipid profiles were also determined. Prior to treatment, ALX-induced hyperglycaemia (>250 mg/dL was established in rats. Oral administration of 30 and 75 mg/kg b. wt. HILA extract to diabetic rats for 14 days caused significant reduction in FBG to baseline values observed in non-diabetic conditions. Treatment with HILA extract also showed improvement in lipid abnormalities observed in hyperglycaemic condition, levels of triglyceride, total cholesterol and LDL-cholesterol were significantly reduced and HDL-cholesterol increased resulting in improved artherogenic index. Hepatic GLY concentration was significantly increased in diabetic rat treated with the extract. Histological examinations showed degenerated and sparse pancreatic islets β-cells in non-treated diabetic rat, whereas microscopy of treated rats showed mild to normal architecture with enriched β-cells. Preliminary phytochemical profiling of the extract revealed the presence of alkaloids (2.54 mg/g, saponins (0.28 mg/g, phenols (0.04 mg/g and anthraquinones (0.01 mg/g. Results from this study revealed that the aqueous leaf extract of H. indicum possesses not only antihyperglycaemic, but also antidyslipidemic activities, that may prove to be of clinical importance in the management of diabetes and associated secondary complications.

    Although people screened as being hyperglycaemic often fail to follow up with physicians for clinical assessment, epidemiologic findings on the frequency and predictors of not following up (hereafter, "no follow-up") are lacking. The purpose of this study was to examine the no follow-up rate with physicians after screening for diabetes and predictors of no follow-up. We assessed cases of no follow-up with physicians within six months after screening based on medical claims data from employee-based social health insurance programs in Japan, for people aged 20 to 68 years from 2005 to 2010. Among 3878 screened participants with hyperglycaemia, 2527 (65%) did not follow up with their physicians within six months after screening. Multiple logistic regression analysis revealed that younger age and lower blood glucose level predicted no follow-up among both men and women, while lower body mass index and negative proteinuria also predicted no follow-up among men. Treatment for dyslipidaemia facilitated follow-up among both genders, and treatment for hypertension or depression facilitated follow-up among men. Approximately two thirds of individuals screened as having hyperglycaemia did not follow up with their physicians within six months after screening. Predictors of no follow-up were younger age and milder hyperglycaemia. Being on treatment for co-morbidities tended to facilitate follow-up. Copyright © 2014 Elsevier Ireland Ltd.

    The type II β regulatory subunit of cAMP-dependent protein kinase (RII β ) has been hypothesized to play an important role in the growth inhibition and differentiation induced by site-selective cAMP analogs in human cancer cells, but direct proof of this function has been lacking. To address this tissue, HL-60 human promyelocytic leukemia cells were exposed to RII β antisense synthetic oligodeoxynucleotide, and the effects on cAMP-induced growth regulation were examined. Exposure of these cells to RII β antisense oligodeoxynucleotide resulted in a decrease in cAMP analog-induced growth inhibition and differentiation without apparent effect on differentiation induced by phorbol esters. This loss in cAMP growth regulatory function correlated with a decrease in basal and induced levels of RII β protein. Exposure to RII β sense, RI α and RII α antisense, or irrelevant oligodeoxynucleotides had no such effect. These results show that the RII β regulatory subunit of protein kinase plays a critical role in the cAMP-induced growth regulation of HL-60 leukemia cells

    Leaf extracts of Scoparia dulcis, is used as a herbal remedy by diabetics worldwide. Fresh Scoparia dulcis porridge elicited a low glycaemic index (GI) and anti-hyperglycaemic effects when fed to diabetic Wistar rats. Commercially produced Scoparia dulcis porridge (SDC) elicited medium GI. Present study was aimed at studying the anti-diabetic effects of consumption of commercially produced S. dulcis porridge. A randomized crossover clinical trial with type 2 diabetic patients (n = 35) on medication, with mild and moderate diabetes [fasting blood glucose (FBG) 126-300 mg/dL, age 35-70 years] was conducted. Within the first three months (study period 1) group 1 was the test and group 2 was the control. Following a wash-out period, the two groups were crossed over (study period 2: group 1 - control; group 2 - test). Test group consumed commercially produced SDC for 3 days/week for three months and the control group any other food. At the onset and end of each study period glucose measurements [Fasting Blood Glucose (FBG), HbA1c], lipid measurements (total cholesterol, HDL-C, LDL-C, triglycerides, cholesterol ratios), toxicity parameters (liver enzymes, creatinine, CRP, eGFR) were analyzed by enzyme assay kit methods using a KONELAB 20XT auto analyzer. Significances between groups were analyzed by one way ANOVA (normal distribution) and Mann Whitney test (if the values were not normally distributed). Within group comparisons were carried out by Bonferroni post hoc test. During the crossover clinical trial HbA1c of group 1 decreased from 7.9 ± 0.5 to 6.5 ± 0.3 (p = 0.003) while HbA1c of group 2 decreased from 7.0 ± 0.3to 6.7 ± 0.3 while in the test group. Therefore, both test groups (1 and 2) elicited a decrease in HbA1c compared to respective control groups. Both test groups elicited a non significant decrease in FBG following the intervention (group 1 - from 174 ± 14 to 160 ± 10 mg/dL; group 2 - from 183 ± 13 to 160 ± 7 mg/dL). No significant differences (p >0

    Berberine is a plant alkaloid with multiple pharmacological actions, including antidiarrhoeal activity and has been shown to inhibit Cl(-) secretion in distal colon. The aims of this study were to determine the molecular signaling mechanisms of action of berberine on Cl(-) secretion and the ion transporter targets. Monolayers of T84 human colonic carcinoma cells grown in permeable supports were placed in Ussing chambers and short-circuit current measured in response to secretagogues and berberine. Whole-cell current recordings were performed in T84 cells using the patch-clamp technique. Berberine decreased forskolin-induced short-circuit current in a concentration-dependent manner (IC(50) 80 ± 8 μM). In apically permeabilized monolayers and whole-cell current recordings, berberine inhibited a cAMP-dependent and chromanol 293B-sensitive basolateral membrane K(+) current by 88%, suggesting inhibition of KCNQ1 K(+) channels. Berberine did not affect either apical Cl(-) conductance or basolateral Na(+)-K(+)-ATPase activity. Berberine stimulated p38 MAPK, PKCα and PKA, but had no effect on p42\\/p44 MAPK and PKCδ. However, berberine pre-treatment prevented stimulation of p42\\/p44 MAPK by epidermal growth factor. The inhibitory effect of berberine on Cl(-) secretion was partially blocked by HBDDE (∼65%), an inhibitor of PKCα and to a smaller extent by inhibition of p38 MAPK with SB202190 (∼15%). Berberine treatment induced an increase in association between PKCα and PKA with KCNQ1 and produced phosphorylation of the channel. We conclude that berberine exerts its inhibitory effect on colonic Cl(-) secretion through inhibition of basolateral KCNQ1 channels responsible for K(+) recycling via a PKCα-dependent pathway.

  11. Low doses of cholera toxin and its mediator cAMP induce CTLA-2 secretion by dendritic cells to enhance regulatory T cell conversion.

    Cinthia Silva-Vilches

    Full Text Available Immature or semi-mature dendritic cells (DCs represent tolerogenic maturation stages that can convert naive T cells into Foxp3+ induced regulatory T cells (iTreg. Here we found that murine bone marrow-derived DCs (BM-DCs treated with cholera toxin (CT matured by up-regulating MHC-II and costimulatory molecules using either high or low doses of CT (CThi, CTlo or with cAMP, a known mediator CT signals. However, all three conditions also induced mRNA of both isoforms of the tolerogenic molecule cytotoxic T lymphocyte antigen 2 (CTLA-2α and CTLA-2β. Only DCs matured under CThi conditions secreted IL-1β, IL-6 and IL-23 leading to the instruction of Th17 cell polarization. In contrast, CTlo- or cAMP-DCs resembled semi-mature DCs and enhanced TGF-β-dependent Foxp3+ iTreg conversion. iTreg conversion could be reduced using siRNA blocking of CTLA-2 and reversely, addition of recombinant CTLA-2α increased iTreg conversion in vitro. Injection of CTlo- or cAMP-DCs exerted MOG peptide-specific protective effects in experimental autoimmune encephalomyelitis (EAE by inducing Foxp3+ Tregs and reducing Th17 responses. Together, we identified CTLA-2 production by DCs as a novel tolerogenic mediator of TGF-β-mediated iTreg induction in vitro and in vivo. The CT-induced and cAMP-mediated up-regulation of CTLA-2 also may point to a novel immune evasion mechanism of Vibrio cholerae.

    Full Text Available Background. Hypoxis hemerocallidea is a native plant that grows in the Southern African regions and is well known for its beneficial medicinal effects in the treatment of diabetes, cancer, and high blood pressure. Aim. This study evaluated the effects of Hypoxis hemerocallidea on oxidative stress biomarkers, hepatic injury, and other selected biomarkers in the liver and kidneys of healthy nondiabetic and streptozotocin- (STZ- induced diabetic male Wistar rats. Materials and Methods. Rats were injected intraperitoneally with 50 mg/kg of STZ to induce diabetes. The plant extract-Hypoxis hemerocallidea (200 mg/kg or 800 mg/kg aqueous solution was administered (daily orally for 6 weeks. Antioxidant activities were analysed using a Multiskan Spectrum plate reader while other serum biomarkers were measured using the RANDOX chemistry analyser. Results. Both dosages (200 mg/kg and 800 mg/kg of Hypoxis hemerocallidea significantly reduced the blood glucose levels in STZ-induced diabetic groups. Activities of liver enzymes were increased in the diabetic control and in the diabetic group treated with 800 mg/kg, whereas the 200 mg/kg dosage ameliorated hepatic injury. In the hepatic tissue, the oxygen radical absorbance capacity (ORAC, ferric reducing antioxidant power (FRAP, catalase, and total glutathione were reduced in the diabetic control group. However treatment with both doses improved the antioxidant status. The FRAP and the catalase activities in the kidney were elevated in the STZ-induced diabetic group treated with 800 mg/kg of the extract possibly due to compensatory responses. Conclusion. Hypoxis hemerocallidea demonstrated antihyperglycemic and antioxidant effects especially in the liver tissue.

    In this study, the functional role of two cAMP-response elements (CRE) in the promoter of the chinook salmon GH gene and their interactions with the transcription factor Pit-1 in regulating GH gene expression were examined. A chimeric construct of the chloramphenicol acetyltransferase (CAT) reporter gene with the CRE-containing GH promoter (pGH.CAT) was transiently transfected into primary cultures of rainbow trout pituitary cells. The expression of CAT activity was stimulated by an adenylate cyclase activator forskolin as well as a membrane-permeant cAMP analog 8-bromo-cAMP. Furthermore, these stimulatory responses were inhibited by a protein kinase A inhibitor H89, suggesting that these CREs are functionally coupled to the adenylate cyclase-cAMP-protein kinase A cascade. This hypothesis is supported by parallel studies using GH4ZR7 cells, a rat pituitary cell line stably transfected with dopamine D2 receptors. In this cell line, D2 receptor activation is known to inhibit adenylate cyclase activity and cAMP synthesis. Stimulation with a nonselective dopamine agonist, apomorphine, or a D2-specific agonist, Ly171555, suppressed the expression of pGH.CAT in GH4ZR7 cells, and this inhibition was blocked by simultaneous treatment with forskolin. These results indicate that inhibition of the cAMP-dependent pathway reduces the basal promoter activity of the CRE-containing pGH.CAT. The functionality of these CREs was further confirmed by deletion analysis and site-specific mutagenesis. In trout pituitary cells, the cAMP inducibility of pGH.CAT was inhibited after deleting the CRE-containing sequence from the GH promoter. When the CRE-containing sequence was cloned into a CAT construct with a viral thymidine kinase promoter, a significant elevation of cAMP inducibility was observed. This stimulatory response, however, was abolished by mutating the core sequence, CGTCA, in these CREs, suggesting that these cis-acting elements confer cAMP inducibility to the salmon GH gene

    Full Text Available Abstract Background Elevated non-esterified fatty acids (NEFA concentrations in non-pregnant animals have been reported to decrease pancreatic responsiveness. As ovine gestation advances, maternal insulin concentrations fall and NEFA concentrations increase. Experiments were designed to examine if the pregnancy-associated rise in NEFA concentration is associated with a reduced pancreatic sensitivity to glucose in vivo. We investigated the possible relationship of NEFA concentrations in regulating maternal insulin concentrations during ovine pregnancy at three physiological states, non-pregnant, non-lactating (NPNL, 105 and 135 days gestational age (dGA, term 147+/- 3 days. Methods The plasma concentrations of insulin, growth hormone (GH and ovine placental lactogen (oPL were determined by double antibody radioimmunoassay. Insulin responsiveness to glucose was measured using bolus injection and hyperglycaemic clamp techniques in 15 non-pregnant, non-lactating ewes and in nine pregnant ewes at 105 dGA and near term at 135 dGA. Plasma samples were also collected for hormone determination. In addition to bolus injection glucose and insulin Area Under Curve calculations, the Mean Plasma Glucose Increment, Glucose Infusion Rate and Mean Plasma Insulin Increment and Area Under Curve were determined for the hyperglycaemic clamp procedures. Statistical analysis of data was conducted with Students t-tests, repeated measures ANOVA and 2-way ANOVA. Results Maternal growth hormone, placental lactogen and NEFA concentrations increased, while basal glucose and insulin concentrations declined with advancing gestation. At 135 dGA following bolus glucose injections, peak insulin concentrations and insulin area under curve (AUC profiles were significantly reduced in pregnant ewes compared with NPNL control ewes (p Conclusions Results suggest that despite an acute suppression of circulating NEFA concentrations during pregnancy, the associated steroids and hormones

    Different agents have been investigated for their effects on [ 3 H] glycogen synthesized in mouse cortical slices. Of these noradrenaline, serotonin and histamine induced clear concentration-dependent glycogenesis. [ 3 H] glycogen hydrolysis induced by noradrenaline appears to be mediated by beta-adrenergic receptors because it is completely prevented by timolol, while phentolamine is ineffective. It seems to involve cyclic AMP because it is potentiated in the presence of isobutylmethylxanthine; in addition dibutyryl cyclic AMP (but not dibutyryl cyclic GMP) promotes glycogenolysis. Lower concentrations of noradrenaline were necessary for [ 3 H] glycogen hydrolysis (ECsub(50) 0.5μM) than for stimulation of cyclic AMP accumulation (ECsub(50) = 8μM). After subchronic reserpine treatment the concentration-response curve to noradrenaline was significantly shifted to the left (ECsub(50) = 0.09 +- 0.02 μM as compared with 0.49 +- 0.08μM in saline-pretreated mice) without modifications of either the basal [ 3 H] glycogen level, maximal glycogenolytic effect, or the dibutyryl cAMP-induced glycogenolytic response. In addition to noradrenaline, clear concentration-dependent [ 3 H] glycogen hydrolysis was observed in the presence of histamine or serotonin. In contrast to the partial [ 3 H] glycogen hydrolysis elicited by these biogenic amines, depolarization of the slices by 50 mM K + provoked a nearly total [ 3 H] glycogen hydrolysis. (author)

    Hyperglycaemia initiates endothelial dysfunction causing diabetic macro- and micro-vasculopathy, the main causes of morbidity and mortality in diabetes mellitus. The vasculopathy exhibits gender peculiarities. We therefore explored gender differences in comparing the effects of hyperglycaemia (50 mM) per se with its hyperosmolar (50 mM) effects on vascular tissue responses to insulin. Endothelium-intact or denuded thoracic aortic rings from age-matched male and female Sprague-Dawley rats were incubated for 10 min or 6 h (acute versus chronic exposure) in normal, hyperglycaemic or hyperosmolar Krebs solution. Relaxant responses to insulin (6.9x10(-7)-6.9x10(-5) M) of the phenylephrine-contracted tissues were recorded. Endothelium denudation in both genders inhibited relaxation to insulin in all conditions, more significantly in female than in male tissues, suggesting the female response to insulin is more endothelium-dependent than the male. Acutely and chronically exposed normoglycemic endothelium-intact or -denuded tissues responded similarly to insulin. Chronic hyperglycemic or hyperosmolar exposure did not alter the endothelium-denuded tissue responses to insulin, whereas the responses of the endothelium-intact male and female hyperosmolar, and male hyperglycemic tissues were enhanced. The results show that insulin exerts an endothelium-dependent and independent relaxation with the female tissue responses more endothelium-dependent than the male. The data also suggest that hyperosmolarity per se enhances aortic tissue relaxant responses to insulin whereas hyperglycemia per se inhibits the same and more so in female than male tissues. These effects are endothelium-dependent. Copyright (c) 2010 Elsevier B.V. All rights reserved.

    Multiple myeloma is an incurable disease requiring the development of effective therapies which can be used clinically. We have elucidated the potential for manipulating the cAMP signaling pathway as a target for inhibiting the growth of multiple myeloma cells. As a model system, we primarily used the murine multiple myeloma cell line MOPC315 which can be grown both in vivo and in vitro. Human multiple myeloma cell lines U266, INA-6 and the B-cell precursor acute lymphoblastic leukemia cell line Reh were used only for in vitro studies. Cell death was assessed by flow cytometry and western blot analysis after treatment with cAMP elevating agents (forskolin, prostaglandin E2 and rolipram) and cAMP analogs. We followed tumor growth in vivo after forskolin treatment by imaging DsRed-labelled MOPC315 cells transplanted subcutaneously in BALB/c nude mice. In contrast to the effect on Reh cells, 50 μM forskolin more than tripled the death of MOPC315 cells after 24 h in vitro. Forskolin induced cell death to a similar extent in the human myeloma cell lines U266 and INA-6. cAMP-mediated cell death had all the typical hallmarks of apoptosis, including changes in the mitochondrial membrane potential and cleavage of caspase 3, caspase 9 and PARP. Forskolin also inhibited the growth of multiple myeloma cells in a mouse model in vivo. Elevation of intracellular levels of cAMP kills multiple myeloma cells in vitro and inhibits development of multiple myeloma in vivo. This strongly suggests that compounds activating the cAMP signaling pathway may be useful in the field of multiple myeloma

    There is no evidence in fish brain demonstrating the existence of changes in lactate metabolism in response to alterations in glucose levels. We induced in rainbow trout through intraperitoneal (IP) treatments, hypoglycaemic or hyperglycaemic changes to assess the response of parameters involved in lactate metabolism in glucosensing areas like hypothalamus and hindbrain. To distinguish those effects from those induced by peripheral changes in the levels of metabolites or hormones, we also carried out intracerebroventricular (ICV) treatments with 2-deoxy-D-glucose (2-DG, a non-metabolizable glucose analogue thus inducing local glucopenia) or glucose. Finally, we also incubated hypothalamus and hindbrain in vitro in the presence of increased glucose concentrations. The changes in glucose availability were in general correlated to changes in the amount of lactate in both areas. However, when we assessed in these areas the response of parameters related to lactate metabolism, the results obtained were contradictory. The increase in glucose levels did not produce in general the expected changes in those pathways with only a minor increase in their capacity of lactate production. The decrease in glucose levels was, however, more clearly related to a decreased capacity of the pathways involved in the production and use of lactate, and this was especially evident after ICV treatment with 2-DG in both areas. In conclusion, the present results while addressing the existence of changes in lactate metabolism after inducing changes in glucose levels in brain glucosensing areas only partially support the possible existence of an astrocyte-neuron lactate shuttle in hypothalamus and hindbrain of rainbow trout relating glucose availability to lactate production and use.

  10. Regulation of cAMP Responsive Element Binding Protein 3-Like 1 (Creb3l1 Expression by Orphan Nuclear Receptor Nr4a1

    2017-12-01

    Full Text Available Cyclic AMP (cAMP inducible transcription factor cAMP responsive element binding protein 3 like 1 (Creb3l1 is strongly activated in the hypothalamus in response to hyperosmotic cues such as dehydration (DH. We have recently shown that Creb3l1 expression is upregulated by cAMP pathways in vitro, however the exact mechanisms are not known. Here we show that increasing Creb3l1 transcription by raising cAMP levels in mouse pituitary AtT20 cells automatically initiates cleavage of Creb3l1, leading to a greater abundance of the transcriptionally active N-terminal portion. Inhibiting protein synthesis indicated that de novo protein synthesis of an intermediary transcription factor was required for Creb3l1 induction. Strategic mining of our microarray data from dehydrated rodent hypothalamus revealed four candidates, reduced to two by analysis of acute hyperosmotic-induced transcriptional activation profiles in the hypothalamus, and one, orphan nuclear receptor Nr4a1, by direct shRNA mediated silencing in AtT20 cells. We show that activation of Creb3l1 transcription by Nr4a1 involves interaction with a single NBRE site in the promoter region. The ability to activate Creb3l1 transcription by this pathway in vitro is dictated by the level of methylation of a CpG island within the proximal promoter/5′UTR of this gene. We thus identify a novel cAMP-Nr4a1-Creb3l1 transcriptional pathway in AtT20 cells and also, our evidence would suggest, in the hypothalamus.

    Scoparia dulcis L. commonly known as 'Sweet Broomweed' is widely used in Indian folk medicine for the treatment of diabetes mellitus. Oral administration of 0.15, 0.30 and 0.45 g/kg body weight of the aqueous extract of the Scoparia dulcis leaves (SLEt) for 45 days resulted in a significant reduction in blood glucose, glycosylated haemoglobin and an increase in total haemoglobin but in the case of 0.45 g/kg body weight the effect was highly significant. The aqueous extract also prevented a decrease in the body weight. An oral glucose tolerance test was also performed in experimental diabetic rats, in which there was a significant improvement in glucose tolerance in animals treated with SLEt and the effect was comparable to that of glibenclamide.

    Several studies with diabetes-specific formulas (DSFs) for hyperglycaemic patients in need of nutritional support have been conducted in non-malnourished patients, mainly comparing products with varying macronutrient compositions. Here, the effect of a high energy, high protein DSF on postprandial responses was compared to a product with a similar macronutrient composition in malnourished or at risk of malnutrition patients with type 2 diabetes. In this randomised, double-blind cross-over study, 20 patients were included. After overnight fasting, patients consumed 200 mL of a DSF or standard supplement (control) (19.6 g protein, 31.2 g carbohydrates and 10.6 g fat), while continuing their anti-diabetic medication. The formulas differed in type of carbohydrates and presence of fibre. The postprandial glucose, insulin and glucagon responses were monitored over 4 h. Data were analysed with a Linear Mixed Model, and results of the modified ITT population (n = 19) are shown. Postprandial glucose response as incremental area under the curve (iAUC), was lower after consumption of DSF compared with control (489.7 ± 268.5 (mean ± SD) vs 581.3 ± 273.9 mmol/L min, respectively; p = 0.008). Also, the incremental maximum concentration of glucose (iCmax) was lower for DSF vs control (3.5 ± 1.4 vs 4.0 ± 1.4 mmol/L; p = 0.007). Postprandial insulin and glucagon levels, expressed as iAUC or iCmax, were not significantly different between groups. Consumption of a high energy, high protein DSF by older malnourished or at risk of malnutrition type 2 diabetes patients resulted in a significantly lower glucose response compared to control. These data suggest that the use of a DSF is preferred for patients with diabetes in need of nutritional support. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    The effect of food intake on caveolin expression in relation to insulin signalling was studied in skeletal muscle and adipocytes from retroperitoneal (RP) and subcutaneous (SC) adipose tissue, comparing fasted (F) to not fasted (NF) rats that had been fed a control or high-fat (HF) diet for 72 days. Serum glucose was analysed enzymatically and insulin and leptin by ELISA. Caveolins and insulin signalling intermediaries (IR, IRS-1 and 2 and GLUT4) were determined by RT-PCR and western blotting. Caveolin and IR phosphorylation was measured by immunoprecipitation. Data were analysed with Mann-Whitney U test. High-fat fed animals showed metabolic alterations and developed obesity and insulin resistance. In skeletal muscle, food intake (NF) induced activation of IR and increased expression of IRS-2 in control animals with normal metabolic response. HF animals became overweight, hyperglycaemic, hyperinsulinemic, hyperleptinemic and showed insulin resistance. In skeletal muscle of these animals, food intake (NF) also induced IRS-2 expression together with IR, although this was not active. Caveolin 3 expression in this tissue was increased by food intake (NF) in animals fed either diet. In RP adipocytes of control animals, food intake (NF) decreased IR and IRS-2 expression but increased that of GLUT4. A similar but less intense response was found in SC adipocytes. Food intake (NF) did not change caveolin expression in RP adipocytes with either diet, but in SC adipocytes of HF animals a reduction was observed. Food intake (NF) decreased caveolin-1 phosphorylation in RP but increased it in SC adipocytes of control animals, whereas it increased caveolin-2 phosphorylation in both types of adipocytes independently of the diet. Animals fed a control-diet show a normal response to food intake (NF), with activation of the insulin signalling pathway but without appreciable changes in caveolin expression, except a small increase of caveolin-3 in muscle. Animals fed a high-fat diet

  8. Responsible tourism

    Birkaš E.

    2012-01-01

    Full Text Available Realising tourism in the context of responsibility is a problem of historical-social and economic time-space continuum; the problem of possibility of temporal unification of these parts. The study aims to emphasize that the essence of problem can only be understood in the depth of a general problematic of tourism, as a question of temporalisation of historical-social space, which, however, leads to a grand question of today: does the human activity which creates temporalised spaces have its own gravitational direction? Ad deliberandum. The study proposes the viewpoint that the context of responsibility requires overcoming the dimension of interpretation where the subject is understood as an ultimate human-singularity and a perfect match of responsibility with a dominant and current form of temporalisation of time suggests a paradigm of participating consciousness, the consciousness of unity, which, in Berdyaev's words, is never logical, but existential. The study, on the basis of a meticulous studying of a new narrative of tourism, primarily due to volume restrictions does not go beyond presenting the key attributes of this ever-expanding understanding of tourism - with a demonstration of a concrete practice - but all this with an emphasis that qualification of the actors' activities is possible only along the lines of a previous consideration of comprehension of structure of space and time - along the revalorisation of a motivational horison (Anzenbacher, A 1987, 264.p. and also the very term of responsibility and freedom. Responsibility can only then become an orientation of tourist activities, if the primary focus is set on re-comprehension (revalorisation of civilisational legacies in a timeless perspective.

    In the contemporary debate on the use of the neurosciences in ethics and law, numerous arguments have been bandied about among scientists and philosophers looking to uphold or reject the reliability and validity of scientific findings obtained by brain imaging technologies. Among the most vexing questions is, Can we trust that technology? One point of disagreement is whether brain scans offer a window through which to observe the functioning of the mind, in such a way as to enable lawyers, judges, physicians, and lawmakers to detect anomalies in brain function that may account for criminal unconscious behavior. Those who stand behind brain imaging believe that this can indeed be achieved, whereas those in opposition stress that brain scans are highly open to interpretation and that the data they provide is insufficient to establish causal connections. The question essentially comes down to whether technology can reliably be used to determine the intentions of the individual, thus establishing mens rea, for example, and hence responsibility. This article focuses on the latter notion and explores whether we can rely on the neurosciences to shed light on a complex form of moral and legal reasoning, as well as the role of the neurosciences in reawakening a philosophical and legal interest in trying to set responsibility on an empirical basis.

The dark side of the extraordinary dynamism of innovation lies precisely in its destructive power. If simply left to market forces, it could lead to social chaos and great human suffering. To face the challenges of our time, we must create the proper climate and culture to develop strong entrepreneurial drive. But, more than ever, we must give this entrepreneurial drive its ethical and societal dimensions. Responsible innovation means a more voluntary orientation towards the great problems of the 21st century, e.g. depletion of the planet's resources, rising inequality, and new scientific developments potentially threatening freedom, democracy and human integrity. We need to transform our ceaseless creativity into real progress for humankind. In this respect, the rapid development of social innovation opens the door for new methods an...

    Philosophical reflections on the concepts of responsibility and type of responsibility are presented and discussed with regard to the developments of technology. The author states that neither the relationship between liability and responsibility has changed, nor the structure of responsibility. Any individual still is responsible for his actions and their consequences. What has changed, however, is the former restriction to the concept of internal responsibility and the overlapping of acting subject and responsible subject. (DG) [de

    Radioadaptive response is a biological defense mechanism in which low-dose ionizing irradiation elicits cellular resistance to the genotoxic effects of subsequent irradiation. However, its molecular mechanism remains largely unknown. We previously demonstrated that the dose recognition and adaptive response could be mediated by a feedback signaling pathway involving protein kinase C (PKC), p38 mitogen activated protein kinase (p38MAPK) and phospholipase C (PLC). Further, to elucidate the downstream effector pathway, we studied the X-ray-induced adaptive response in cultured mouse and human cells with different genetic background relevant to the DNA damage response pathway, such as deficiencies in TP53, DNA-PKcs, ATM and FANCA genes. The results showed that p53 protein played a key role in the adaptive response while DNA-PKcs, ATM and FANCA were not responsible. Wortmannin, a specific inhibitor of phosphatidylinositol 3-kinase (PI3K), mimicked the priming irradiation in that the inhibitor alone rendered the cells resistant against the induction of chromosome aberrations and apoptosis by the subsequent X-ray irradiation. The adaptive response, whether it was afforded by low-dose X-rays or wortmannin, occurred in parallel with the reduction of apoptotic cell death by challenging doses. The inhibitor of p38MAPK which blocks the adaptive response did not suppress apoptosis. These observations indicate that the adaptive response and apoptotic cell death constitute a complementary defense system via life-or-death decisions. The p53 has a pivotal role in channeling the radiation-induced DNA double-strand breaks (DSBs) into an adaptive legitimate repair pathway, where the signals are integrated into p53 by a circuitous PKC-p38MAPK-PLC damage sensing pathway, and hence turning off the signals to an alternative pathway to illegitimate repair and apoptosis. A possible molecular mechanism of adaptive response to low-dose ionizing irradiation has been discussed in relation to

  3. Biological Responses to Materials

    Anderson, James M.

    2001-08-01

    All materials intended for application in humans as biomaterials, medical devices, or prostheses undergo tissue responses when implanted into living tissue. This review first describes fundamental aspects of tissue responses to materials, which are commonly described as the tissue response continuum. These actions involve fundamental aspects of tissue responses including injury, inflammatory and wound healing responses, foreign body reactions, and fibrous encapsulation of the biomaterial, medical device, or prosthesis. The second part of this review describes the in vivo evaluation of tissue responses to biomaterials, medical devices, and prostheses to determine intended performance characteristics and safety or biocompatibility considerations. While fundamental aspects of tissue responses to materials are important from research and development perspectives, the in vivo evaluation of tissue responses to these materials is important for performance, safety, and regulatory reasons.

    2016-09-01

    Full Text Available Because of the transcendent nature of the experience of my own self, responsibility for myself necessarily leads to responsibility for others. The aim of this paper is to approach this experience of the transcendence of the self and to show how it relates to a new sense of responsibility which transcends the self through a number of stages. First, the author outlines what might be called the "standard" view of authenticity in Husserl and how this particular view yields a certain view of responsibility as the ability to answer completely for "who" one is and "what" one does. Second, this standard view is challenged with another reading of the "self" in Husserl – one that emphasizes a necessary and productive division within the self. Thus, the author suggests that it is this second view of the self which is developed by Heidegger. Third, he demonstrates how this different view of the "authentic" self, that is inextricably linked to a "loss" of self, leads to a radically distinct view of responsibility for oneself, and for others.

    1991-10-01

    Much of what used to be called immunotherapy is now included in the term biological response modifiers. Biological response modifiers (BRMs) are defined as those agents or approaches that modify the relationship between the tumor and host by modifying the host's biological response to tumor cells with resultant therapeutic effects.'' Most of the early work with BRMs centered around observations of spontaneous tumor regression and the association of tumor regression with concurrent bacterial infections. The BRM can modify the host response in the following ways: Increase the host's antitumor responses through augmentation and/or restoration of effector mechanisms or mediators of the host's defense or decrease the deleterious component by the host's reaction; Increase the host's defenses by the administration of natural biologics (or the synthetic derivatives thereof) as effectors or mediators of an antitumor response; Augment the host's response to modified tumor cells or vaccines, which might stimulate a greater response by the host or increase tumor-cell sensitivity to an existing response; Decrease the transformation and/or increase differentiation (maturation) of tumor cells; or Increase the ability of the host to tolerate damage by cytotoxic modalities of cancer treatment.

    Rapid response systems are commonly employed by hospitals to identify and respond to deteriorating patients outside of the intensive care unit. Controversy exists about the benefits of rapid response systems. We aimed to review the current state of the rapid response literature, including evolving aspects of afferent (risk detection) and efferent (intervention) arms, outcome measurement, process improvement, and implementation. Articles written in English and published in PubMed. Rapid response systems are heterogeneous, with important differences among afferent and efferent arms. Clinically meaningful outcomes may include unexpected mortality, in-hospital cardiac arrest, length of stay, cost, and processes of care at end of life. Both positive and negative interventional studies have been published, although the two largest randomized trials involving rapid response systems - the Medical Early Response and Intervention Trial (MERIT) and the Effect of a Pediatric Early Warning System on All-Cause Mortality in Hospitalized Pediatric Patients (EPOCH) trial - did not find a mortality benefit with these systems, albeit with important limitations. Advances in monitoring technologies, risk assessment strategies, and behavioral ergonomics may offer opportunities for improvement. Rapid responses may improve some meaningful outcomes, although these findings remain controversial. These systems may also improve care for patients at the end of life. Rapid response systems are expected to continue evolving with novel developments in monitoring technologies, risk prediction informatics, and work in human factors. Copyright © 2018 Elsevier B.V.

    Full Text Available Steady improvements in technologies that measure human emotional response offer new possibilities for making computer games more immersive. This paper reviews the history of designs a particular branch of affective technologies that acquire electrodermal response readings from human subjects. Electrodermal response meters have gone through continual improvements to better measure these nervous responses, but still fall short of the capabilities of today's technology. Electrodermal response traditionally have been labor intensive. Protocols and transcription of subject responses were recorded on separate documents, forcing constant shifts of attention between scripts, electrodermal measuring devices and of observations and subject responses. These problems can be resolved by collecting more information and integrating it in a computer interface that is, by adding relevant sensors in addition to the basic electrodermal resistance reading to untangle (1 body resistance; (2 skin resistance; (3 grip movements; other (4 factors affecting the neural processing for regulation of the body. A device that solves these problems is presented and discussed. It is argued that the electrodermal response datastreams can be enriched through the use of added sensors and a digital acquisition and processing of information, which should further experimentation and use of the technology.

    Full Text Available Oil palm (Elaeis guineensis leaves extract (OPLE has antioxidant properties and because oxidative stress contributes to the pathogenesis of diabetic nephropathy (DN, we tested the hypothesis that OPLE prevents diabetes renal oxidative stress, attenuating injury. Sprague-Dawley rats received OPLE (200 and 500 mg kg−1 for 4 and 12 weeks after diabetes induction (streptozotocin 60 mg kg−1. Blood glucose level, body and kidney weights, urine flow rate (UFR, glomerular filtration rate (GFR, and proteinuria were assessed. Oxidative stress variables such as 8-hydroxy-2′-deoxyguanosine (8-OHdG, glutathione (GSH, and lipid peroxides (LPO were quantified. Renal morphology was analysed, and plasma transforming growth factor-beta1 (TGF-β1 was measured. Diabetic rats demonstrated increase in blood glucose and decreased body and increased kidney weights. Renal dysfunction (proteinuria, elevations in UFR and GFR was observed in association with increases in LPO, 8-OHdG, and TGF-β1 and a decrease in GSH. Histological evaluation of diabetic kidney demonstrated glomerulosclerosis and tubulointerstitial fibrosis. OPLE attenuated renal dysfunction, improved oxidative stress markers, and reduced renal pathology in diabetic animals. These results suggest OPLE improves renal dysfunction and pathology in diabetes by reducing oxidative stress; furthermore, the protective effect of OPLE against renal damage in diabetes depends on the dose of OPLE as well as progression of DN.

    Diabetes mellitus is an endocrine disease of multiple aetiologies in insulin secretion. A deficiency in insulin results in hyperglycemia with metabolic disturbances of biomolecules. Moringa oleifera (MO) is endemic in the tropics with a variety of ethnomedicinal importance. The leaf of this plant has been reported to possess antioxidant and medicinal properties that may be helpful in the treatment and management of diabetes and its associated complications. Diabetes was induced intraperitoneally in rats by a single dose of streptozotocin (55 mg/kg) and treated with methanolic extract of Moringa oleifera (250 mg/kg b.wt) for six weeks. Forty-eight (48) adult male Wistar strain rats were randomly divided into four groups: normal control (NC), Moringa oleifera treated control rats (NC + MO), diabetic rats (DM) and Moringa oleifera treated diabetic rats (DM + MO). Estimation of antioxidant capacity, total polyphenols, flavonoids and flavonols content of Moringa oleifera extract was performed and serum biochemical markers were evaluated. Antioxidants such as catalase (CAT), glutathione peroxidase (GPx), superoxide dismutase (SOD) activities, glutathione (GSH) and inflammatory biomarkers were determined in the kidney. Results showed high antioxidant capacities of MO extract and improved serum biochemical markers, whilst lipid peroxidation (MDA) levels were reduced in non-diabetic and diabetic rats after MO treatment when compared to normal control. Subsequent administration of MO led to an increased concentration of serum albumin, globulin and total protein with a decrease in the level of MDA, and improvements in CAT, SOD, GSH, GPx, (tumour necrosis factor-alpha)TNF-α and (interleukin-6)IL-6. MO contains potent phytochemical constituents that offer protective action against diabetic-induced renal damage, reactive oxygen species (ROS) and inflammation and could therefore play a role in reducing diabetic complications, particularly in developing countries such as in Africa where the majority cannot afford orthodox medicine.

    Banana is an extensively cultivated plant worldwide, mainly for its fruit, while its ancillary product, the banana flower is consumed as a vegetable and is highly recommended for diabetics in the traditional Indian medicine system. This study is based on an investigation of the in vivo antihyperglycaemic activity of Umbelliferone (C1) and Lupeol (C2) isolated from the ethanol extract of banana flower (EF) in alloxan induced diabetic rat model. Diabetic rats which were administered with C1, C2 and EF (100 and 200 mg/kg b. wt.) for 4 weeks showed deterioration in fasting hyperglycaemia and reversal of abnormalities in serum/urine protein, urea and creatinine, when compared to the diabetic control group of rats. The diabetic group of rats fed with EF, C1 and C2 (100 mg/kg b. wt.) once daily, for a period of 28 days resulted in a significant reduction of diabetic symptoms viz., polyphagia, polydipsia, polyuria and urine sugar together with an improved body weight. HbA1c extent was reduced whereas levels of insulin and Hb were increased. Both the extract and compounds wielded positive impacts in diabetic rats by reversal of altered activities of hepatic marker enzymes viz., aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP); glycolytic enzyme (hexokinase); shunt enzyme (glucose-6-phosphate dehydrogenase); gluconeogenic enzymes (glucose-6-phosphatase, fructose-1,6-bisphosphatase, lactate dehydrogenase) and pyruvate kinase. The characteristic diabetic complications such as hypercholesterolemia and hypertriacylglycerolemia also significantly reverted to normal in the serum/liver of diabetic rats. Besides these, the treatment increased the activities of enzymatic and non-enzymatic antioxidants in the serum and liver. The histological observations revealed a marked regeneration of the β-cells in the drug treated diabetic rats. In conclusion, the present study illustrates that EF, C1 and C2 enhances the glycolytic activities, besides increasing the hepatic glucose utilization in diabetic rats by stimulating insulin secretion from the remnant β-cells along with potential enzymatic and non-enzymatic antioxidant activities.

    Neutron response of the albedo type dosimeter is strongly dependent on the energy of the incident neutrons as well as the moderating material on the backside of the dosimeter. This study characterizes the response of the Hanford dosimeter for a variety of neutron energies for both a water and Rando phantom (a simulated human body consisting of an actual human skeleton with plastic for body muscles and certain organs). The Hanford dosimeter response to neutrons of different energies is typical of albedo type dosimeters. An approximate two orders of magnitude difference in response is observed between neutron energies of 100 keV and 10 MeV. Methods were described to compensate for the difference in dosimeter response between a laboratory neutron spectrum and the different spectra encountered at various facilities in the field. Generally, substantial field support is necessary for accurate neutron dosimetry

    Extreme emergency events of national significance that include manmade and natural disasters seem to have become more frequent during the past two decades. The Nation is becoming more resilient to these emergencies through better preparedness, reduced duplication, and establishing better communications so every response and recovery effort saves lives and mitigates the long-term social and economic impacts on the Nation. The National Response Framework (NRF) (http://www.fema.gov/NRF) was developed to provide the guiding principles that enable all response partners to prepare for and provide a unified national response to disasters and emergencies. The NRF provides five key principles for better preparation, coordination, and response: 1) engaged partnerships, 2) a tiered response, 3) scalable, flexible, and adaptable operations, 4) unity of effort, and 5) readiness to act. The NRF also describes how communities, tribes, States, Federal Government, privatesector, and non-governmental partners apply these principles for a coordinated, effective national response. The U.S. Geological Survey (USGS) has adopted the NRF doctrine by establishing several earth-sciences, discipline-level teams to ensure that USGS science, data, and individual expertise are readily available during emergencies. The Geospatial Information Response Team (GIRT) is one of these teams. The USGS established the GIRT to facilitate the effective collection, storage, and dissemination of geospatial data information and products during an emergency. The GIRT ensures that timely geospatial data are available for use by emergency responders, land and resource managers, and for scientific analysis. In an emergency and response capacity, the GIRT is responsible for establishing procedures for geospatial data acquisition, processing, and archiving; discovery, access, and delivery of data; anticipating geospatial needs; and providing coordinated products and services utilizing the USGS' exceptional pool of

    Frequency response has received a lot of attention in recent years at the national level, which culminated in the development and approval of North American Electricity Reliability Corporation (NERC) BAL-003-1 Frequency Response and Frequency Bias Setting Reliability Standard. This report is prepared to describe the details of the work conducted by Pacific Northwest National Laboratory (PNNL) in collaboration with the Bonneville Power Administration and Western Electricity Coordinating Council (WECC) Joint Synchronized Information Subcommittee (JSIS) to develop a frequency response analysis tool (FRAT). The document provides the details on the methodology and main features of the FRAT. The tool manages the database of under-frequency events and calculates the frequency response baseline. Frequency response calculations are consistent with frequency response measure (FRM) in NERC BAL-003-1 for an interconnection and balancing authority. The FRAT can use both phasor measurement unit (PMU) data, where available, and supervisory control and data acquisition (SCADA) data. The tool is also capable of automatically generating NERC Frequency Response Survey (FRS) forms required by BAL-003-1 Standard.

Although responsible business notion is generally known, its details, ways of preparing strategy, instruments and what is more its benefits are still narrowly spread. Many business people face the lack of knowledge and information, which on one hand make it easier to spread and deepen wrong stereotypes connected with this notion and on the other hand make business people unwilling to implement CRS in their companies. The subjects of this article are examples of instruments which are responsible for realization of social responsibility strategy.

    Many important gains have been made in understanding PTSD and other responses to trauma as a result of neuroscience-based observations. Yet there are many gaps in our knowledge that currently impede our ability to predict those who will develop pathologic responses. Such knowledge is essential for developing appropriate strategies for mounting a mental health response in the aftermath of terrorism and for facilitating the recovery of individuals and society. This paper reviews clinical and biological studies that have led to an identification of pathologic responses following psychological trauma, including terrorism, and highlights areas of future-research. It is important to not only determine risk factors for the development of short- and long-term mental health responses to terrorism, but also apply these risk factors to the prediction of such responses on an individual level. It is also critical to consider the full spectrum of responses to terrorism, as well as the interplay between biological and psychological variables that contribute to these responses. Finally, it is essential to remove the barriers to collecting data in the aftermath of trauma by creating a culture of education in which the academic community can communicate to the public what is and is not known so that survivors of trauma and terrorism will understand the value of their participation in research to the generation of useful knowledge, and by maintaining the acquisition of knowledge as a priority for the government and those involved in the immediate delivery of services in the aftermath of large-scale disaster or trauma.

    Roga, W; Illuminati, F; Giampaolo, S M

    2014-01-01

    The presence of quantum correlations in a quantum state is related to the state's response to local unitary perturbations. Such a response is quantified by the distance between the unperturbed and perturbed states, minimized with respect to suitably identified sets of local unitary operations. In order to be a bona fide measure of quantum correlations, the distance function must be chosen among those that are contractive under completely positive and trace preserving (CPTP) maps. The most relevant instances of such physically well-behaved metrics include the trace, the Bures, and the Hellinger distance. To each of these metrics one can associate the corresponding discord of response, namely the trace, or Hellinger, or Bures minimum distance from the set of unitarily perturbed states. All these three discords of response satisfy the basic axioms for a proper measure of quantum correlations. In the present work we focus in particular on the Bures distance, which enjoys the unique property of being both Riemannian and contractive under CPTP maps, and admits important operational interpretations in terms of state distinguishability. We compute analytically the Bures discord of response for two-qubit states with maximally mixed marginals and we compare it with the corresponding Bures geometric discord, namely the geometric measure of quantum correlations defined as the Bures distance from the set of classical-quantum states. Finally, we investigate and identify the maximally quantum correlated two-qubit states according to the Bures discord of response. These states exhibit a remarkable nonlinear dependence on the global state purity. (paper)

  18. Planned home birth: the professional responsibility response.

    Chervenak, Frank A; McCullough, Laurence B; Brent, Robert L; Levene, Malcolm I; Arabin, Birgit

    2013-01-01

    This article addresses the recrudescence of and new support for midwife-supervised planned home birth in the United States and the other developed countries in the context of professional responsibility. Advocates of planned home birth have emphasized patient safety, patient satisfaction, cost effectiveness, and respect for women's rights. We provide a critical evaluation of each of these claims and identify professionally appropriate responses of obstetricians and other concerned physicians to planned home birth. We start with patient safety and show that planned home birth has unnecessary, preventable, irremediable increased risk of harm for pregnant, fetal, and neonatal patients. We document that the persistently high rates of emergency transport undermines patient safety and satisfaction, the raison d'etre of planned home birth, and that a comprehensive analysis undermines claims about the cost-effectiveness of planned home birth. We then argue that obstetricians and other concerned physicians should understand, identify, and correct the root causes of the recrudescence of planned home birth; respond to expressions of interest in planned home birth by women with evidence-based recommendations against it; refuse to participate in planned home birth; but still provide excellent and compassionate emergency obstetric care to women transported from planned home birth. We explain why obstetricians should not participate in or refer to randomized clinical trials of planned home vs planned hospital birth. We call on obstetricians, other concerned physicians, midwives and other obstetric providers, and their professional associations not to support planned home birth when there are safe and compassionate hospital-based alternatives and to advocate for a safe home-birth-like experience in the hospital.

    The integrity of a nuclear power plant during a postulated seismic event is required to protect the public against radiation. Therefore, a detailed set of seismic analyses of various structures and equipment is performed while designing a nuclear power plant. This report describes the structural response analysis method, including the structural model, soil-structure interaction as it relates to structural models, methods for seismic structural analysis, numerical integration methods, methods for non-seismic response analysis approaches for various response combinations, structural damping values, nonlinear response, uncertainties in structural properties, and structural response analysis using random properties. The report describes the state-of-the-art in these areas for nuclear power plants. It also details the past studies made at Sargent and Lundy to evaluate different alternatives and the conclusions reached for the specific purposes that those studies were intended. These results were incorporated here because they fall into the general scope of this report. The scope of the present task does not include performing new calculations

    These lectures present the theory of the nuclear response in the Random Phase Approximation (RPA). In the first lecture, various relations are derived between densities and currents which give rise to the well-known sum rules. Then RPA is derived via the time-dependent Hartree theory. The various formulations of RPA are shown: the configuration space representation, the coordinate space representation, the Landau theory of infinite systems and the RPA for separable interactions constrained by consistency. The remarkable success of RPA in describing the collective density oscillations of closed shell nuclei is illustrated with a few examples. In the final lecture, the σtau response is discussed with the application of simple theoretical considerations to the empirical data. Finally, we point out several problems which remain in the response theory. (author)

    Knowledge about cellular events in mammalian cells exposed to low doses of ionizing radiation is meager. Recent works showed that human lymphocytes become resistant to radiation-induced chromosomal damage after exposure to low doses of ionizing radiation. Experimental evidence for radio-adaptive response (RAR) in cultured mammalian cells was obtained. Exposure to very low doses of gamma-rays or tritium beta-rays make cells less susceptible to the induction of micronuclei and sister chromatid exchanges by subsequent higher doses. Many important characteristics of the novel response suggest that RAR is a stress response resulting in the enhanced repair of chromosomal DNA damage in cell under restricted conditions. Experiments are still in progress in order to elucidate the molecular basis for RAR processes. (author). 13 refs.; 2 figs., 1 tab

    An adaptive response to radiation stress was found in cultured Chinese hamster V79 cells, as a suppressed induction of micronuclei (MNs) and sister chromatid exchanges (SCEs) in the cells conditioned by very low doses. The important characteristics of the novel chromosomal response, called radio-adaptive response (RAR), that have newly emerged in this study are: 1) Low doses of beta-rays from tritiated water (HTO) as well as tritiated thymidine can cause the RAR. 2) Thermal neutrons, a high LET radiation, can not act as tritium beta-rays or gamma-rays. 3) The RAR expression is suppressed by an inhibition of protein synthesis. 4) Several proteins are newly synthesized concurrently with the RAR expression after adapting doses, viewed by two-dimensional electrophoresis of cellular proteins. These results suggest that the RAR is an adaptive chromosomal DNA repair induced by very low doses of low LET radiations under restricted conditions, accompanying the inducible specific gene expression.

    Emery, K.; Dunlavy, D.; Field, H.; Moriarty, T. [National Renewable Energy Lab., Golden, CO (United States)

    1998-09-01

    This paper discusses the various elemental random and nonrandom error sources in typical spectral responsivity measurement systems. The authors focus specifically on the filter and grating monochrometer-based spectral responsivity measurement systems used by the Photovoltaic (PV) performance characterization team at NREL. A variety of subtle measurement errors can occur that arise from a finite photo-current response time, bandwidth of the monochromatic light, waveform of the monochromatic light, and spatial uniformity of the monochromatic and bias lights; the errors depend on the light source, PV technology, and measurement system. The quantum efficiency can be a function of he voltage bias, light bias level, and, for some structures, the spectral content of the bias light or location on the PV device. This paper compares the advantages and problems associated with semiconductor-detector-based calibrations and pyroelectric-detector-based calibrations. Different current-to-voltage conversion and ac photo-current detection strategies employed at NREL are compared and contrasted.

    The objective of this review is to stimulate the reader's considerations for developing community disaster mitigation. Disaster mitigation begins long before impact and is defined as the actions taken by a community to eliminate or minimize the impact of a disaster. The assessment of vulnerabilities, the development of infrastructure, memoranda of understanding, and planning for a sustainable response and recovery are parts of the process. Empowering leadership and citizens with knowledge of available resources through the planning and development of a disaster response can strengthen a community's resilience, which can only add to the viability and quality of life enjoyed by the entire community.

Low doses of β-rays from tritiated water (HTO) as well as tritium-thymidine can cause RAR. 2. Thermal neutrons, a high LET radiation, can not act as tritium β-rays or γ-rays. 3. The RAR expression is suppressed not only by the treatment with an inhibitor of protein synthesis but also by RNA synthesis inhibition. 4. Several proteins are newly synthesized concurrently with the RAR expression after the adapting doses, viewed by two-dimensional electrophoresis of cellular proteins. These results suggests that the RAR might be a cellular stress response to a signal produced preferentially by very low doses of low LET radiation under restricted conditions, accompany the inducible specific gene expression.

  5. The desmoplastic response

    Fearns, C.

    1989-04-01

    Desmoplasia, a process in which excessive connective tissue is deposited in a neoplasm, is discussed. To study the process, a human malignant melanoma cell line (UCT-Mel 7) was used, that was established in the laboratory, and when injected into athymic mice, it gave rise to tumours that showed a number of interesting features. The tumour induced a marked desmoplastic response and the desmoplasia was associated in UCT-Mel 7-derived tumours with an unusual phasic pattern of growth. Two possible mechanisms were identified by which UCT-Mel 7 cells could have induced the desmoplastic response. UCT-Mel 7 cells were shown to be chemotactic for mouse macrophages and human foreskin fibroblasts were stimulated, in a dose-dependent manner, to synthesize increased amounts of collagen when co-cultured with mouse peritoneal exudate cells. Tumour cells were also found to act directly. Co-culture of UCT-Mel 7 cells and fibroblasts resulted in increased collagen synthesis by the fibroblasts. DNA synthesis was not required. Dexamethasone, retinoic acid and the tumour promoter, phorbol myristate acetate, had significant primary effects on fibroblast collagen synthesis but did not modify the response to melanoma cells. Recombinant basic fibroblast growth factor did not seem to be involved in the desmoplastic response. A surprising finding was the production of a potent inhibitor of collagen synthesis by superinduced cells of the mouse macrophage cell line, P388D 1 . This inhibitor has not been fully characterised. 49 figs., 33 tabs., 362 refs

    Griffiths, M.

    1996-01-01

    After the Chernobyl accident, it became painfully obvious to the international community that there was an urgent need to establish a system for the coordination of international disaster assistance. It became the task of the United Nations Office for Disaster Relief (UNDRO) to develop such a system. The former UNDRO was subsumed into the Department of Humanitarian Affairs (DHA), established in January 1992 on the basis of UN General Assembly Resolution 46/182 adopted in December 1991, and the disaster relief system presently found in DHA is a further evolution of the system established by UNDRO. One particular importance in relation to nuclear accidents is the fact that UNDRO and the International Atomic Energy Agency (IAEA) signed a Memorandum of Understanding defining their respective responsibilities and the need for cooperation in case of accidents involving the unintentional release of nuclear radiation. In essence, the MOU makes it clear that the responsibilities of the IAEA, in connection with accidents at Nuclear Power Plants, related to the technical and radiological aspects, in particular to accident prevention, to the on-site preparedness, and to remedial measures within the 30-km zone outside the NPP. DHA's responsibilities, on the other hand, relate to the general preparedness and the rescue efforts outside the 30 km zone. In this respect, the preparedness and emergency response system is no different from the system employed in any other type of sudden-onset emergency

    Since the early 2000s, the field of Responsible Conduct of Research has become widely recognized as essential to scientific education, investigation, and training. At present, research institutions with public funding are expected to have some minimal training and education in RCR for their graduate students, fellows and trainees. These institutions also are expected to have a system in place for investigating and reporting misconduct in research or violations of regulations in research with human subjects, or in their applications to federal agencies for funding. Public scrutiny of the conduct of scientific researchers remains high. Media reports of misconduct scandals, biased research, violations of human research ethics rules, and moral controversies in research occur on a weekly basis. Since the 2009 publication of the 2nd edition of Shamoo and Resnik's Responsible Conduct of Research, there has been a vast expansion in the information, knowledge, methods, and diagnosis of problems related to RCR and the ...

  3. Conceptualising environmental responsibility

    International Nuclear Information System (INIS)

    Lenzen, Manfred; Murray, Joy

    2010-01-01

    Downstream responsibility is rarely addressed in the academic literature and in corporate sustainability reporting. We conceptualise downstream responsibility for the example of carbon emissions, by establishing a terminology as well as a framework for quantifying downstream carbon footprints. By extracting emissions-intensive sales chains for a number of Australian industry sectors, and comparing these to emissions-intensive supply chains, we demonstrated the ability of input-output analysis to quantify emissions responsibility in both directions. We extend the definition of downstream responsibility beyond the product use and disposal phases, to include what we call 'enabled' emissions. This term implies that whatever is sold downstream enables our customers to operate and emit, irrespective of whether it is our product that is combusted, or that directly combusts fuels, or not. Our structural path analyses and threshold-capture relationships reveal stark differences between industries with regard to the data collection efforts necessary to achieve a reasonably complete footprint assessment. Industries appear to have their own specific carbon footprint profiles, and one cannot design generic relevance tests that tell which data to collect. Moreover we conclude that current completeness standards in carbon reporting cannot be satisfied using relevance thresholds. Input-output analysis and structural path analysis are excellent tools that can help companies undertake screening exercises, which in turn help prioritising and streamlining the collection of data needed to establish a corporate downstream carbon footprint. Compared to conventional manual approaches, hybrid life-cycle assessments assisted by input-output analysis and structural path analysis achieve more complete results, with substantially less staff, money and time.

    Ni Choileain, Niamh

    2012-02-03

    OBJECTIVES: To describe the profound alterations in host immunity that are produced by major surgery as demonstrated by experimental and clinical studies, and to evaluate the benefits of therapeutic strategies aimed at attenuating perioperative immune dysfunction. DATA SOURCES: A review of the English-language literature was conducted, incorporating searches of the MEDLINE, EMBASE, and Cochrane collaboration databases to identify laboratory and clinical studies investigating the cellular response to surgery. STUDY SELECTION: Original articles and case reports describing immune dysfunction secondary to surgical trauma were included. DATA EXTRACTION: The results were compiled to show outcomes of different studies and were compared. DATA SYNTHESIS: Current evidence indicates that the early systemic inflammatory response syndrome observed after major surgery that is characterized by proinflammatory cytokine release, microcirculatory disturbance, and cell-mediated immune dysfunction is followed by a compensatory anti-inflammatory response syndrome, which predisposes the patient to opportunistic infection, multiple organ dysfunction syndrome, and death. Because there are currently no effective treatment options for multiple organ dysfunction syndrome, measures to prevent its onset should be initiated at an early stage. Accumulating experimental evidence suggests that targeted therapeutic strategies involving immunomodulatory agents such as interferon gamma, granulocyte colony-stimulating factor, the prostaglandin E(2) antagonist, indomethacin, and pentoxifylline may be used for the treatment of systemic inflammatory response syndrome to prevent the onset of multiple organ dysfunction syndrome. CONCLUSIONS: Surgical trauma produces profound immunological dysfunction. Therapeutic strategies directed at restoring immune homeostasis should aim to redress the physiological proinflammatory-anti-inflammatory cell imbalance associated with major surgery.

    Full Text Available Sociological discussion of globalisation is preoccupied with the political, economic, and military dimension of it, with little attention to its religious aspect. This paper attempts to trace the impacts of globalisation on religion and religious responses, the argument of which derives mainly from the so-called “Bridge-Building Program” organised by CRCS & ICRS-UGM in 2008. It argues that though they share a common concern, people of different faiths are at risk of deepening the problems rather than offering solutions in view of their different responses for which we categorise them into different but overlapping categories -ideological, ambivalent, integrative, exclusive, and imitative. It then leads to a more fundamental question of whether interfaith cooperation is possible given those different and sometime opposing responses. [Dalam kajian sosiologi, diskusi mengenai globalisasi kerap kali semata-mata ditinjau dari sisi politik, enonomi dan militer, sementara dimensi agama sering kali dikesampingkan.

  11. Load responsive hydrodynamic bearing

    Science.gov (United States)

    Kalsi, Manmohan S.; Somogyi, Dezso; Dietle, Lannie L.

    2002-01-01

    A load responsive hydrodynamic bearing is provided in the form of a thrust bearing or journal bearing for supporting, guiding and lubricating a relatively rotatable member to minimize wear thereof responsive to relative rotation under severe load. In the space between spaced relatively rotatable members and in the presence of a liquid or grease lubricant, one or more continuous ring shaped integral generally circular bearing bodies each define at least one dynamic surface and a plurality of support regions. Each of the support regions defines a static surface which is oriented in generally opposed relation with the dynamic surface for contact with one of the relatively rotatable members. A plurality of flexing regions are defined by the generally circular body of the bearing and are integral with and located between adjacent support regions. Each of the flexing regions has a first beam-like element being connected by an integral flexible hinge with one of the support regions and a second beam-like element having an integral flexible hinge connection with an adjacent support region. A least one local weakening geometry of the flexing region is located intermediate the first and second beam-like elements. In response to application of load from one of the relatively rotatable elements to the bearing, the beam-like elements and the local weakening geometry become flexed, causing the dynamic surface to deform and establish a hydrodynamic geometry for wedging lubricant into the dynamic interface.

    2014-02-01

    It has been demonstrated that a prolonged period (48 h) of paradoxical sleep deprivation (PSD) potentiates amphetamine (AMP)-induced behavioral sensitization, an animal model of addiction-related neuroadaptations. In the present study, we examined the effects of an acute short-term deprivation of total sleep (TSD) (6h) on AMP-induced behavioral sensitization in mice and compared them to the effects of short-term PSD (6 h). Three-month-old male C57BL/6J mice underwent TSD (experiment 1-gentle handling method) or PSD (experiment 2-multiple platforms method) for 6 h. Immediately after the sleep deprivation period, mice were tested in the open field for 10 min under the effects of saline or 2.0 mg/kg AMP. Seven days later, to assess behavioral sensitization, all of the mice received a challenge injection of 2.0 mg/kg AMP and were tested in the open field for 10 min. Total, peripheral, and central locomotion, and grooming duration were measured. TSD, but not PSD, potentiated the hyperlocomotion induced by an acute injection of AMP and this effect was due to an increased locomotion in the central squares of the apparatus. Similarly, TSD facilitated the development of AMP-induced sensitization, but only in the central locomotion parameter. The data indicate that an acute period of TSD may exacerbate the behavioral effects of AMP in mice. Because sleep architecture is composed of paradoxical and slow wave sleep, and 6-h PSD had no effects on AMP-induced hyperlocomotion or sensitization, our data suggest that the deprivation of slow wave sleep plays a critical role in the mechanisms that underlie the potentiating effects of TSD on both the acute and sensitized addiction-related responses to AMP.

  13. Ontario demand response scenarios

    International Nuclear Information System (INIS)

    Rowlands, I.H.

    2005-09-01

    Strategies for demand management in Ontario were examined via 2 scenarios for a commercial/institutional building with a normal summertime peak load of 300 kW between 14:00 and 18:00 during a period of high electricity demand and high electricity prices. The first scenario involved the deployment of a 150 kW on-site generator fuelled by either diesel or natural gas. The second scenario involved curtailing load by 60 kW during the same periods. Costs and benefits of both scenarios were evaluated for 3 groups: consumers, system operators and society. Benefits included electricity cost savings, deferred transmission capacity development, lower system prices for electricity, as well as environmental changes, economic development, and a greater sense of corporate social responsibility. It was noted that while significant benefits were observed for all 3 groups, they were not substantial enough to encourage action, as the savings arising from deferred generation capacity development do not accrue to individual players. The largest potential benefit was identified as lower prices, spread across all users of electricity in Ontario. It was recommended that representative bodies cooperate so that the system-wide benefits can be reaped. It was noted that if 10 municipal utilities were able to have 250 commercial or institutional customers engaged in distributed response, then a total peak demand reduction of 375 MW could be achieved, representing more than 25 per cent of Ontario's target for energy conservation. It was concluded that demand response often involves the investment of capital and new on-site procedures, which may affect reactions to various incentives. 78 refs., 10 tabs., 5 figs

But a good accountant in handling the numbers can use that skill to misstate earnings to cover a multitude of problems with a company's books while staying within the law. So, the notion of a moral or ethical accountant is not the same as the notion of a good accountant. Our general principle would be that to be ethical a person has a responsibility to fulfil one's role or roles, as long as tha...

    Increasing numbers of clinical research projects are submitted to ethical committees (institutional review boards) for approval. New therapeutic developments have to be evaluated by these committees to protect patients/volunteers. Thus, the responsibility of ethical committees is increasing. The "Nürnberger Kodex" and the "Declaration of Helsinki" are the background for these evaluations. According to the German drug law the physician is obligated by law to submit the protocol to such a committee. In addition, local state physician authorities require such a procedure. Important considerations during the review process besides ethical aspects are the informed consent, which should be written in an understandable form, and the obligations of the insurance.

    While community based crisis response teams offer needed resources to schools impacted by crisis, they are often not asked to help. Reports from crisis team leaders at the school shooting incidents at James W. Parker Middle School, Edinboro, Pennsylvania and Columbine High School, Littleton, Colorado are contrasted regarding utilization of community resources. Factors limiting the usefulness of community based teams include unfamiliarity with school organization, culture, and procedures. Key differences in school vs. community team precepts, decision-making, and strategic paradigms render team coordination difficult. Successful cross training presents opportunities for school-community partnership and utilization of community teams for school duty.

    2016-12-01

    The multilevel empirical study of the antecedents of corporate social responsibility (CSR) has been identified as "the first knowledge gap" in CSR research. Based on an extensive literature review, the present study outlines a conceptual multilevel model of CSR, then designs and empirically validates an operational multilevel model of the principal driving factors affecting corporate environmental responsibility (CER), as a measure of CSR. Both conceptual and operational models incorporate three levels of analysis: institutional, organizational, and individual. The multilevel nature of the design allows for the assessment of the relative importance of the levels and of their components in the achievement of CER. Unweighted least squares (ULS) regression analysis reveals that the institutional-level variables have medium relationships with CER, some variables having a negative effect. The organizational level is revealed as having strong and positive significant relationships with CER, with organizational culture and managers' attitudes and behaviors as significant driving forces. The study demonstrates the importance of multilevel analysis in improving the understanding of CSR drivers, relative to single level models, even if the significance of specific drivers and levels may vary by context.

This study investigates the role of pleasure (P, arousal (A and domination (D emotions in mobile’s photo camera advertisement and how each of them is influencing consumer attitude towards the advertisement and brand. Prior Work. Holbrook and Batra (1987 developed their own emotional scale based on these three dimensions (PAD, showing that these emotions mediate consumer responses to advertising. Approach. A 1*4 factorial experiment design method was adopted in order to measure the impact of independent variables (emotion type on dependent variables (attitude toward ad, attitude toward brand. Results. The results revealed that emotions like Pleasure (loving, friendly, grateful and Arousal (active, interested, excited, entertained influence consumers' attitudes towards brand and advertising. Value. Marketers need to understand the role of pleasure and arousal emotions when making advertising campaign; an effective promotion leads to persuading consumers. The results indicate that marketing practitioners should measure affective responses when testing an advertisement, as long as this action would predict brand attitude.

  3. State responses to biotechnology.

    Harris, Rebecca C

    2015-01-01

    This article reviews biotechnology legislation in the 50 states for 11 policy areas spanning 1990-2010, an era of immense growth in biotechnology, genetic knowledge, and significant policy development. Policies regarding health insurance, life insurance, long-term care insurance, DNA data bank collection, biotech research protection, biotech promotion and support, employment discrimination, genetic counselor licensing, human cloning, and genetic privacy each represent major policy responses arising from biotechnology and coinciding with key areas of state regulation (insurance, criminal justice, economic development, labor law, health and safety, privacy, and property rights). This analysis seeks to answer three questions regarding biotechnology legislation at the state level: who is acting (policy adoption), when is policy adopted (policy timing), and what is policy doing (policy content). Theoretical concerns examine state ideology (conservative or liberal), policy type (economic or moral), and the role of external events (federal law, news events, etc.) on state policy adoption. Findings suggest ideological patterns in adoption, timing, and content of biotech policy. Findings also suggest economic policies tend to be more uniform in content than moral policies, and findings also document a clear link between federal policy development, external events, and state policy response.

  4. Human sexual response.

    2015-01-01

    The human sexual response to sexually arousing stimuli is a motivational incentive-based cycle comprising subjective experience and physiologic changes. Clinical and empirical data support a circular model of overlapping phases of variable order. Brain imaging data of sexual arousal identify areas of cerebral activation and inhibition reflecting a complex network of cognitive, motivational, emotional, and autonomic components. Psychologic and biologic factors influence the brain's appraisal and processing of sexual stimuli to allow or disallow subsequent arousal. The sexual and non-sexual outcomes influence motivation to future sexual intimacy. Variability is marked both between individuals and within a person's sexual life, influenced by multiple factors, including stage of life cycle, mental health, and relationship happiness. Neurologic disease can interrupt the cycle at many points: by limiting motivation, reducing ability to attend to and feel sexual stimuli, and accomplishing the movements needed to stimulate and experience intercourse. Impairments to genital congestion, penile erection, and orgasm may also occur. Disease-associated changes to the interpersonal relationship and self-image plus frequently comorbid depression will tend to lessen motivation and temper the brain's appraisal of sexual stimuli, so precluding arousal. Therapy begins by explaining the sexual response cycle, clarifying the points of interruption in the patient's own cycle so as to guide treatment. © 2015 Elsevier B.V. All rights reserved.

Life in the society means more than a simple coexistence of human beings, it actually means living together, collaborating and cooperating; that is why I always have to relate to other people and to be aware that only by limiting my freedom of action, the others freedom is feasible. Neminem laedere should be a principle of life for each of us. The individual is a responsible being. But responsibility exceeds legal prescriptions. Romanian Constitution underlines that I have to exercise my rights and freedoms in good faith, without infringing the rights and freedoms of others. The legal norm, developer of the constitutional principles, is endowed with sanction, which grants it exigibility. But I wonder: If I choose to obey the law, is my decision essentially determined only due of the fear of punishment? Is it not because I am a rational being, who developed during its life a conscience towards values, and thus I understand that I have to respect the law and I choose to comply with it?

  6. Exercise Responses after Inactivity

    Science.gov (United States)

    Convertino, Victor A.

    1986-01-01

    The exercise response after bed rest inactivity is a reduction in the physical work capacity and is manifested by significant decreases in oxygen uptake. The magnitude of decrease in maximal oxygen intake V(dot)O2max is related to the duration of confinement and the pre-bed-rest level of aerobic fitness; these relationships are relatively independent of age and gender. The reduced exercise performance and V(dot)O2max following bed rest are associated with various physiological adaptations including reductions in blood volume, submaximal and maximal stroke volume, maximal cardiac output, sceletal muscle tone and strength, and aerobic enzyme capacities, as well as increases in venous compliance and submaximal and maximal heart rate. This reduction in physiological capacity can be partially restored by specific countermeasures that provide regular muscular activity or orhtostatic stress or both during the bed rest exposure. The understanding of these physiological and physical responses to exercise following bed rest inactivity has important implications for the solution to safety and health problems that arise in clinical medicine, aerospace medicine, sedentary living, and aging.

    Resource-management techniques must be applied to assess the risks, benefits, priorities, and potentials of the different energy options as prospective slowdowns in the flow of crude oil threaten recurring energy crises. The 23 contributors to this book use various managerial approaches in the formulation of energy policies. There is little agreement among the remedies put forth as to which policies will best achieve a balanced energy system. While some experts argue that Canadian energy policy should emphasize intensive development of coal, others claim that it ought to strive for greater reliance on electricity, and still others contend that the transition to soft energy paths is a preferable policy approach. The essays offer a broad range of policy responses, examining not only technical and economic possibilities, but political and institutional alternatives as well. 147 references, 18 figures, 30 tables.

    There is little correlation between public response to perceived risks and the life-expectancy statistics for hazardous occupations. Case studies show that the public reacts more strongly to conflicting information from the warnings of experts and the media, giving more credence to individual situations than to statistical probabilities. The impact of a large-scale accident intensifies the perception of risk even though the situation may be safer over time. These factors affect the public's ability to accept nuclear power and its insistence on public debate, which may shift from the area of facts and documentation to that of values. Decision makers may need to compromise by shifting expenditures to actions that involve low levels of risk. 2 references, 1 figure, 2 tables. (DCK)

    A pizza restaurant must provide product, in the form of the food and drink, and service in the way this is delivered to the customer. Providing this has distinct operational challenges, but what if the restaurant also provides a home delivery service? The service becomes deployed as the customer is no-longer co-located with the production area. The business challenge is complicated as service needs to be delivered within a geographic region, to time or the pizza will be cold, and within a cost that is not ­prohibitive. It must also be responsive to short term demand; needing to balance the number of staff it has available to undertake deliveries against a forecast of demand.

    Full text: Currently, the evaluation of response to therapy in Oncology consists of determination of changes in size of lesions measurable by structural imaging, notably computerized tomography. These criteria, formalized using RECIST (Response Evaluation Criteria in Solid Tumors), are the current standard for evaluation (http://www3.cancer. gov/dip/RECIST.htm). An increasing body of evidence suggests that functional changes in tumors precede structural changes, and that methodologies that measure such changes may be able to evaluate the potential of therapy, allowing for better and earlier selection of these potentially cytotoxic therapies. Nuclear Medicine imaging is distinguished by its ability to determine functional characteristics. These include: 1. Receptor status - for example, the presence of sodium iodide symporters detected by radioiodine or pertechnetate imaging, the presence of somatostatin or norepinephrine receptors by pentetreotide or metaiodobenzylguanidine (mIBG) imaging respectively. Such imaging can help guide appropriate therapies with iodine-131, somatostatin analogues (radiolabeled or otherwise) or iodine-131 labeled mIBG. 2. Metabolic status - for example, glycolytic status (with fluorine-18 labeled fluorodeoxyglucose); amino acid metabolism (e.g. using carbon-11 labeled methionine), or tumor proliferation (using radiolabeled thymidine or deoxyuridine). These methods have advantages over structural imaging because in the vast majority of tumors, changes in the functional or molecular status of tumors are seen earlier than are structural changes. 3. Overall cellular status - these imaging agents are still in their early development but hold great promise for the determination of cellular viability. Annexin imaging is the archetype of such imaging modalities that predict the overall fate of the cell, in this instance its entry into the apoptotic pathway. This review will highlight the uses of functional imaging using radiotracers in all three

Etiologically, it could be classified as primary and secondary dystonia. Dopa-responsive dystonia (DRD belongs to a group of primary dystonia. The aim of this study was to detect the presence of gene GCH-I mutation in our population in patients with dopa-responsive dystonic dyskinesia and to analyze clinical specificity of the affected. Methods. Out of the group of patients with dystonia of different distribution four patients were separated whose clinical picture indicated the diagnosis of DRD. Two patients had a positive family anamnesis while the other two were sporadic. Genetic analysis was performed by the use of a standard protocol, which included PCR amplification and DNK sequencing according to the method of Senger and autoradiografy. Results. In the patients from the family DRD-1 new hetaerazygote point mutation 520G→A in 4-m exson gene GCH-I was revealed. First symptoms of the disease showed in the age of seven by the torsion of the left foot, progressively advanced and got into the evolution of numbness in the legs, aggravated gait, tending to worsen in the evening, and the therapy with levodopa (500 mg produced a dramatic effect. The second mutation in the female patient from the family DRD-2 was homozygote deletion in1-m intron gene GCH-I (IVS1-85delA. Unwilling torsion of the foot, feeling of weakness in the lower extremities (that caused falling without loss of the consciousness were clinical demonstrations of the disease. The application of levodopa (300 mg caused regression of the symptoms of the disease.

    2001-01-01

    In the past five years, Burrard Clean Operations (BCO) has demonstrated its' oil spill response capabilities through different types of exercises. Such exercises are necessary for certification of Response Organizations in Canada. The exercises can be performed through actual response to spills or through simulated situations. Both can provide an opportunity to practice different levels of response to a range of conditions in various settings. They also provide the opportunity to focus on specific themes that can be part of a response and to identify areas for improvement in response actions. They also make it possible to interface with government agencies, industry and others that participate in spill responses. The exercise program for BCO is aimed at maintaining certification and to assist the Canadian Coast Guard. The exercises broaden the lessons learned and set a course for future enhancement to spill readiness should a real incident occur. The goals of the exercise program are to provide real time drills that show the operational capability of a representative sample of BCO equipment, management and trained spill responders. The response functions of the BCO exercise program are: notification, response organization activation, contractor activation, situation analysis, strategy development for marine oil spill response, site safety, equipment deployment, containment, recovery, shoreline assessment, cleanup, communications, decontamination, logistics, and financial management. The BCO experience has led to the basic conclusions that there is a need to vary the exercise design and format and that there is a need to implement follow-up actions provided during exercise evaluations. 7 refs., 3 tabs

    The obligations under the law relative to the prevention of marine oil spills and the type of emergency plans needed to mitigate any adverse effects caused by a marine oil spill were discussed. The organizational structure, spill response resources and operational management capabilities of Canada's newly created Response Organizations (ROs) were described. The overall range of oil spill response services that the RO provides to the domestic oil handling, oil transportation and the international shipping industries were reviewed. Amendments to the Canada Shipping Act which require that certain ships and oil handling facilities take oil spill preparedness and response measures, including having an arrangement with an RO certified by the Canadian Coast Guard, were outlined. Canadians now benefit from five ROs established to provide coast-to-coast oil spill response coverage. These include the Western Canada Marine Response Corporation, the Canadian Marine Response Management Corporation, the Great Lakes Response Corporation, the Eastern Canada Response Corporation and the Atlantic Emergency Response Team Ltd. ROs have the expertise necessary to organize and manage marine oil spill response services. They can provide equipment, personnel and operational management for the containment, recovery and cleanup of oil spilled on water

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2015v14n3p382 This paper resumes a previous discussion on Environmental Ethics and Irreversibility, which was presented in 2005. There I first faced the problem. Now I would like to reevaluate the issue. Was my paper “catastrophist”? Or was it, instead, realistic? Which are today the main issues confronting Environmental Ethics? Plainly speaking, what can we really do? These are some of the questions I would like to bring in to the debate with my colleagues and the public. In other words, instead of focusing in the aspect of “irreversibility”, I prefer here to focus on the “responsibility” of agents and institutions. It rescues the so-called “Principle of Responsibility”, by Hans Jonas. There is also some debate with Karl-Otto Appel and Habermas. If, on one hand, there are irreversible damages to nature, as the extinction of species and even of natural locations, as rivers and other natural accidents, there are, on the other hand, many actions that can and must be taken in order to preserve or deter the grave consequences of the environmental degradation. In this paper, I try to discuss some of the problems and propose some solutions, but the more important thing is to call everyone – individuals, groups, or institutions – to responsibility face the Earth, the Human and not-human beings, and mainly the future generations.

    Task 5 of the collaborative effort between ORNL, Brazil, and Westinghouse for the International Nuclear Energy Research Initiative entitled 'Development of Advanced Instrumentation and Control for an Integrated Primary System Reactor' focuses on operator control and protection system interaction, with particular emphasis on developing emergency response guidelines (ERGs). As in the earlier tasks, we will use the IRIS plant as a specific example of an integrated primary system reactor (IPSR) design. The present state of the IRIS plant design--specifically, the lack of a detailed secondary system design--precludes establishing detailed emergency procedures at this time. However, we can create a structure for their eventual development. This report summarizes our progress to date. Section 1.2 describes the scope of this effort. Section 2 compares IPSR ERG development to the recent AP1000 effort, and identifies three key plant differences that affect the ERGs and control room designs. The next three sections investigate these differences in more detail. Section 3 reviews the IRIS Safety-by-Design philosophy and its impact on the ERGs. Section 4 looks at differences between the IRIS and traditional loop PWR I and C Systems, and considers their implications for both control room design and ERG development. Section 5 examines the implications of having one operating staff control multiple reactor units. Section 6 provides sample IRIS emergency operating procedures (EOPs). Section 7 summarizes our conclusions

    Full Text Available Arons responds to what he considers to be Glenn's misrepresentations of the tone and content of Short Route To Chaos. He writes that Glenn "appears to be attempting to construct the book's message into just one more salvo fired in the endless school wars. It is anything but....Reading Glenn's review, one is left with the impression that the book is a Christian-bashing, left-leaning, work of communitarian fuzziness in which a legal scholar unaccountably refuses to confine himself to ... technical explication of existing constitutional doctrine." In his response, Arons affirmatively sets out some of the book's main themes of political /cultural conflict over standardized schooling, corrects some of what he sees as Glenn's misunderstandings, and notes that the book itself invites readers to eschew partisanship and recognize that there are deep structural problems in American public education. In closing, Arons uses an example of Glenn's partisan misunderstanding that leads Arons to recommend to the reader that it would be better to read Short Route to Chaos for oneself.

    Powdered enzymes were transformed into their insoluble magnetic derivatives retaining their catalytic activity. Enzyme powders (e.g., trypsin and lipase) were suspended in various liquid media not allowing their solubilization (e.g., saturated ammonium sulfate and highly concentrated polyethylene glycol solutions, ethanol, methanol, 2-propanol) and subsequently cross-linked with glutaraldehyde. Magnetic modification was successfully performed at low temperature in a freezer (−20 °C) using magnetic iron oxides nano- and microparticles prepared by microwave-assisted synthesis from ferrous sulfate. Magnetized cross-linked enzyme powders were stable at least for two months in water suspension without leakage of fixed magnetic particles. Operational stability of magnetically responsive enzymes during eight repeated reaction cycles was generally without loss of enzyme activity. Separation of magnetically modified cross-linked powdered enzymes from reaction mixtures was significantly simplified due to their magnetic properties. - Highlights: • Cross-linked enzyme powders were prepared in various liquid media. • Insoluble enzymes were magnetized using iron oxides particles. • Magnetic iron oxides particles were prepared by microwave-assisted synthesis. • Magnetic modification was performed under low (freezing) temperature. • Cross-linked powdered trypsin and lipase can be used repeatedly for reaction.

    Photochemical and immunologic knowledge about photoallergy to chemicals is briefly summarized. Studies in in vitro systems have demonstrated that photoallergic compounds can covalently bond to proteins through a photochemical reaction. The immunologic nature of the photoallergic response is based mainly on clinical observations, induction of photoallergy in man and in guinea-pigs and on results of in vitro immunologic tests. Studies of the photoreactions of the photoallergic compound, 3,3',4',5-tetrachlorosalicylanilide (TCSA) with proteins are discussed. TSCA noncovalently bonds to human serum albumin prior to irradiation. Prior interaction is essential for formation of a photoaddition product indicating that a short-lived reactive species derived from TCSA is involved in the photoaddition and limiting the number of skin proteins which can participate in antigen formation. By fragmentation of the TCSA-albumin photoadduct with CNBr, it was determined that TCSA can bond to at least three sites on the albumin molecule. TCSA alone can sensitize the photooxidation of histidine in albumin.

    Full Text Available Given the importance of entrepreneurial activities as an engine of economic growth and poverty alleviation, the issue of business development and entrepreneurial activities, has received increasing attention from a number of interested parties worldwide and also in the Czech Republic. The focus of this paper is on a social economy, a social responsibility and social enterprises. The development of the social economy framework will be introduced in the European context and specifically in the Czech Republic. A case study of a Czech social entrepreneur will be introduced based on qualitative research, namely the biographical narrative method.Social enterprises can support activities of various target groups, such as economic activities of mentally and physically handicapped people, which often operate in economically and socially marginalized situations, including stereotyped images. They give them a chance to become active members of society. In this way they can help to reduce the poverty on a local level. The aim of this paper is to introduce a social entrepreneurship as important part of social economy development in the Czech Republic.

    The Developing Countries Vaccine Manufacturers' Network (DCVMN) held its fifteenth annual meeting from October 27-29, 2014, New Delhi, India. The DCVMN, together with the co-organizing institution Panacea Biotec, welcomed over 240 delegates representing high-profile governmental and nongovernmental global health organizations from 36 countries. Over the three-day meeting, attendees exchanged information about their efforts to achieve their shared goal of preventing death and disability from known and emerging infectious diseases. Special praise was extended to all stakeholders involved in the success of polio eradication in South East Asia and highlighted challenges in vaccine supply for measles-rubella immunization over the coming decades. Innovative vaccines and vaccine delivery technologies indicated creative solutions for achieving global immunization goals. Discussions were focused on three major themes including regulatory challenges for developing countries that may be overcome with better communication; global collaborations and partnerships for leveraging investments and enable uninterrupted supply of affordable and suitable vaccines; and leading innovation in vaccines difficult to develop, such as dengue, Chikungunya, typhoid-conjugated and EV71, and needle-free technologies that may speed up vaccine delivery. Moving further into the Decade of Vaccines, participants renewed their commitment to shared responsibility toward a world free of vaccine-preventable diseases. Copyright © 2015 The Authors.

    1984-01-01

    The author, vice-president of the Federal Constitutional Court, delivered this opening address at the international symposium on nuclear liability held in Munich in September 1984 by OECD/NEA and IAEA. He starts by asking: Where does danger begin, where does risk end. It is the true and original task of the state to keep damage away from its citizens: this entails the obligation for additional garantees - not withstanding an almost greatest possible degree of safety - to at least helpfully compensate damage incurred, should such damage arise. In case of really severe accidents the essential thing is not the operator's liability but the entry of the state into that obligation, and this fact remains unchanged even if the maximum limits of liability were raised or in case of their removal. Therefore it is not necessary to be cautious about the question of unlimited liability, i.e. the unlimited entry of the state into such obligations, especially as all those responsible are convinced that there is practically no risk of that contingency occurring.

    Consumption of alcoholic beverages is widespread through much of the world, and significantly impacts human health and well-being. We sought to determine the contribution of orosensation ('taste') to several alcohol intake measures by examining general responsiveness to taste and somatosensory stimuli in a convenience sample of 435 adults recruited from six cohorts. Each cohort was divided into quantiles based on their responsiveness to sweet, sour, bitter, salty, umami, metallic, and astringent stimuli, and the resulting quantiles pooled for analysis (Kruskal-Wallis ANOVA). Responsiveness to bitter and astringent stimuli was associated in a non-linear fashion with intake of all alcoholic beverage types, with the highest consumption observed in middle quantiles. Sourness responsiveness tended to be inversely associated with all measures of alcohol consumption. Regardless of sensation, the most responsive quantiles tended to drink less, although sweetness showed little relationship between responsiveness and intake. For wine, increased umami and metallic responsiveness tended to predict lower total consumption and frequency. A limited examination of individuals who abstain from all alcohol indicated a tendency toward higher responsiveness than alcohol consumers to sweetness, sourness, bitterness, and saltiness (biserial correlation), suggesting that broadly-tuned orosensory responsiveness may be protective against alcohol use and possibly misuse. Overall, these findings confirm the importance of orosensory responsiveness in mediating consumption of alcohol, and indicate areas for further research. Copyright © 2017. Published by Elsevier Inc.

  2. Hidden Markov Item Response Theory Models for Responses and Response Times.

    2016-01-01

    Current approaches to model responses and response times to psychometric tests solely focus on between-subject differences in speed and ability. Within subjects, speed and ability are assumed to be constants. Violations of this assumption are generally absorbed in the residual of the model. As a result, within-subject departures from the between-subject speed and ability level remain undetected. These departures may be of interest to the researcher as they reflect differences in the response processes adopted on the items of a test. In this article, we propose a dynamic approach for responses and response times based on hidden Markov modeling to account for within-subject differences in responses and response times. A simulation study is conducted to demonstrate acceptable parameter recovery and acceptable performance of various fit indices in distinguishing between different models. In addition, both a confirmatory and an exploratory application are presented to demonstrate the practical value of the modeling approach.

    Radiation oncology is in the middle of the most exciting developments in its 100-year history. Progress in treatment planning and delivery, in medical imaging and in basic cancer and normal tissue biology is likely to change the indication for radiotherapy as well as the way it is prescribed and delivered. Technological and conceptual advances, in particular the development of the multi-leaf collimator and the concept of inverse treatment planning, have led to the introduction of intensity modulated radiation therapy (IMRT) with its capability to plan and deliver non-uniform dose distributions in the clinic. This has forced us to re-think radiation oncology: refining the indication for radiotherapy, optimizing the prescription of dose distributions and considering how, based on clinical evidence, radiation can best be combined with other treatment modalities, surgery, cytotoxic chemotherapy and biologically targeted therapies. The attraction of radiation therapy as an element of multi-modality cancer therapy is that it induces DNA damage that can be modulated in space and time. Progress in basic cancer biology, genomics and proteomics, as well as biological imaging provides novel avenues for individualization of cancer therapy and for biological optimization of radiotherapy. In improving cancer care, it is the therapeutic ratio, rather than tumour control per se, that must be optimised. Interestingly, the two main avenues for improving the effectiveness of radiotherapy currently being actively pursued in the clinic generally aim at different sides of the therapeutic ratio: 3D conformal radiotherapy and IMRT predominantly aim to reduce normal-tissue side effects - and by doing this, open the way for dose escalation that may lead to increased tumour control rates - whereas combined radio-chemotherapy aims to improve tumour response - while keeping the fingers crossed that this will not increase normal-tissue complications to the same extent. In parallel with these

  6. Increasing paternal responsibility.

    Science.gov (United States)

    Cutright, P

    1985-01-01

    Increasing numbers of fathers of children born out of wedlock are not contributing to these children's economic support. In 1981, a tiny minority (14%) of the 1.7 million never-married mothers living with a child with an absent father had a child-support award, and of these, just 112,000 actually received some payment in 1981. The high rates of noncompliance, and the low level of legal efforts to enforce child support, are the result of attempts to collect payments through inefficient traditional methods, not the inability of fathers to pay, a Wisconsin study has shown. A basic problem with collecting child support under the present system is that it relies on fathers to control their expenditures and voluntarily to send the payment on a weekly, biweekly or monthly basis, year after year. As a Wisconsin study shows, full compliance with court-ordered payments dropped from 38% in the 1st year to below 20% by the 5th year among 163 ex-husbands tracked. A proposal by researchers at the University of Wisconsin's Institute for Research on Poverty calls for an "absent-parent tax." The Wisconsin Plan, as it is known, is simply a withholding tax based on the father's gross income and the number of his absent children. If his income falls below a certain level, payments will stop automatically, but will resume if and when it rises above the cutoff point. The Wisconsin plan removes all judicial discretion and lawyer's skill as factors in child-support awards, thus eliminating erratic awards. It also insures that support payments will be maintained during periods of conflict between the father and mother. However, before the Wisconsin Plan can effectively protect children both out of wedlock, a feature needs to be added that will establish paternity at birth. Imposing a real child-support obligation on fathers of children born outside of marriage will introduce a potentially powerful economic incentive for responsible male reproductive and parental behavior.

  12. Demand response in energy markets

    International Nuclear Information System (INIS)

    Skytte, K.; Birk Mortensen, J.

    2004-11-01

    Improving the ability of energy demand to respond to wholesale prices during critical periods of the spot market can reduce the total costs of reliably meeting demand, and the level and volatility of the prices. This fact has lead to a growing interest in the short-run demand response. There has especially been a growing interest in the electricity market where peak-load periods with high spot prices and occasional local blackouts have recently been seen. Market concentration at the supply side can result in even higher peak-load prices. Demand response by shifting demand from peak to base-load periods can counteract the market power in the peak-load. However, demand response has so far been modest since the current short-term price elasticity seems to be small. This is also the case for related markets, for example, green certificates where the demand is determined as a percentage of the power demand, or for heat and natural gas markets. This raises a number of interesting research issues: 1) Demand response in different energy markets, 2) Estimation of price elasticity and flexibility, 3) Stimulation of demand response, 4) Regulation, policy and modelling aspects, 5) Demand response and market power at the supply side, 6) Energy security of supply, 7) Demand response in forward, spot, ancillary service, balance and capacity markets, 8) Demand response in deviated markets, e.g., emission, futures, and green certificate markets, 9) Value of increased demand response, 10) Flexible households.

  3. Response moderation models for conditional dependence between response time and response accuracy.

    Bolsinova, Maria; Tijmstra, Jesper; Molenaar, Dylan

    2017-05-01

    It is becoming more feasible and common to register response times in the application of psychometric tests. Researchers thus have the opportunity to jointly model response accuracy and response time, which provides users with more relevant information. The most common choice is to use the hierarchical model (van der Linden, 2007, Psychometrika, 72, 287), which assumes conditional independence between response time and accuracy, given a person's speed and ability. However, this assumption may be violated in practice if, for example, persons vary their speed or differ in their response strategies, leading to conditional dependence between response time and accuracy and confounding measurement. We propose six nested hierarchical models for response time and accuracy that allow for conditional dependence, and discuss their relationship to existing models. Unlike existing approaches, the proposed hierarchical models allow for various forms of conditional dependence in the model and allow the effect of continuous residual response time on response accuracy to be item-specific, person-specific, or both. Estimation procedures for the models are proposed, as well as two information criteria that can be used for model selection. Parameter recovery and usefulness of the information criteria are investigated using simulation, indicating that the procedure works well and is likely to select the appropriate model. Two empirical applications are discussed to illustrate the different types of conditional dependence that may occur in practice and how these can be captured using the proposed hierarchical models. © 2016 The British Psychological Society.

    2017-07-01

    There is increasing evidence that stimuli-responsive nanomaterials have become significantly critical components of modern materials design and technological developments. Recent advances in synthesis and fabrication of stimuli-responsive polymeric nanoparticles with built-in stimuli-responsive components (Part A) and surface modifications of functional nanoparticles that facilitate responsiveness (Part B) are outlined here. The synthesis and construction of stimuli-responsive spherical, core-shell, concentric, hollow, Janus, gibbous/inverse gibbous, and cocklebur morphologies are discussed in Part A, with the focus on shape, color, or size changes resulting from external stimuli. Although inorganic/metallic nanoparticles exhibit many useful properties, including thermal or electrical conductivity, catalytic activity, or magnetic properties, their assemblies and formation of higher order constructs are often enhanced by surface modifications. Section B focuses on selected surface reactions that lead to responsiveness achieved by decorating nanoparticles with stimuli-responsive polymers. Although grafting-to and grafting-from dominate these synthetic efforts, there are opportunities for developing novel synthetic approaches facilitating controllable recognition, signaling, or sequential responses. Many nanotechnologies utilize a combination of organic and inorganic phases to produce ceramic or metallic nanoparticles. One can envision the development of new properties by combining inorganic (metals, metal oxides) and organic (polymer) phases into one nanoparticle designated as "ceramers" (inorganics) and "metamers" (metallic). © 2017 WILEY-VCH Verlag GmbH & Co.

  12. Psychophysiological responses to Salsa dance.

    Directory of Open Access Journals (Sweden)

    Laura Guidetti

    Full Text Available Speculation exists whether dance provides physiological stimuli adequate to promote health and fitness benefits. Unfortunately, research to date has not addressed the affective and exertional responses to dance. These responses are of interest as positive affective and exertional responses experienced during physical activity may play an important role in predicting adherence. The present study aims to examine the psychophysiological responses of different Salsa dance styles. Ten pairs of dancers performed two different structured lessons of Salsa dance, including Typical Salsa and Rueda de Casino lessons, and a non-structured Salsa dance at a night club. Physiological responses (i.e., percent of heart rate reserve; %HRR were continuously assessed and perceived exertion and affective valence were rated every 15 min throughout the trials. %HRR responses differed between the Salsa dance styles (%HRR from 41.3 to 51.9%, and participants were dancing at intensities near their ventilatory threshold. Specifically, Typical Salsa lesson elicited lower %HRR responses than Rueda de Casino lesson (p 0.05. Surprisingly, exertional (from 8 to 11 and affective (from +3 to +5 responses were unaffected by Salsa dance styles (p > 0.05. These data support that different Salsa dance styles provide physiological stimuli adequate to promote health and fitness benefits, and perhaps more importantly, produce pleasurable experiences, which in turn might lead to an increase in adherence to Salsa dancing which likely provides exercise-like health benefits.

  13. Responsibility is More than Accountability

    DEFF Research Database (Denmark)

    Vetterlein, Antje

    2018-01-01

    This paper critically assesses the notion of responsibility and argues that by adopting a broader understanding as going beyond accountability will shift our focus from regulatory to negotiated governance. Negotiated governance emphasizes the origin of rules and regulations and their contestation...... over the focus on compliance and enforcement. In order to elaborate this argument, I use the case of corporate social responsibility (CSR). The paper takes departure in the governance literature. Reviewing that scholarship, I develop a typology of responsibility to first substantiate the paper's claim...... that responsibility is more than accountability. In a second step, I derive a taxonomy of CSR practices that are loosely associated with different meanings of responsibility. The taxonomy highlights two specific problems that the literature focusing on accountability leaves unanswered, these are the moral...

  15. Seismic response of structures by the response spectrum method

    Hadjian, A.H.

    1981-01-01

    The problems of the acceleration profile at the lower elevations of cantilever structures and the response of relatively rigid structures are explored. It is shown that the use of the conventional methods for the above problems provide very approximate results. An alternate combination of the modal responses is proposed that not only resolves the above problems but also provides better estimates of response for the complete range of structure frequencies. The procedure treats the relative and rigid body responses separately and then appropriately combines the two results. For the rigid range of frequencies (fundamental frequencies greater than about 2 Hz), the proposed procedure does not encounter any numerical difficulties because of the additive nature of the component responses; however, the application of the proposed procedure for very flexible structures causes accuracy problems since the rigid body effects tend to be subtractive from the flexural response of about equal magnitude. For this latter class of problems, the conventional approach of modal combination provides adequate results and avoids the above mentioned numerical difficulties. (orig.)

  16. Responsive self-preservation: Towards an anthropological concept of responsiveness

    Directory of Open Access Journals (Sweden)

    Kasper Lysemose

    2013-12-01

    Full Text Available The aim of this paper is to catch up with a conjecture designated by the term ‘responsive self-preservation’. This term appears neither strikingly beautiful nor intuitively understandable. Obviously it is a convoluted terminus technicus in need of conceptual clarification. The reasons for introducing it should therefore be good. That this is the case cannot be guaranteed from the outset. What can be offered here is a substitution of good reasons with high ambitions: the concept of ‘responsive self-preservation’ is designed to illuminate the conditio humana. In all brevity the claim is that human beings are responsive beings. This means that they do not just exist. In order to do so, they must respond to their existence. On the one hand the inner drive and utmost aspiration in human responsiveness therefore lies in self-preservation. On the other hand self-preservation is thoroughly transformed when embedded into human responsiveness. The article will thus use the concept of responsiveness and the concept of self-preservation to mutually clarify each other – in order to open the possibilities and avoid the pitfalls in each of them. In doing so, it aspires to intervene in contemporary philosophical anthropology.

    The paper investigates the discourse on social responsibility in science as it appears in academic journals. Through database searches a collection of more than 300 papers have been analysed in order to map their answers to the following three questions: - What is the central problem that threatens...... responsibility in science? - What are the central aspects of science or its relation to society that need to be regulated or changed? - What kinds of solutions are imagined and how are these solutions supposed to be put into place? On this basis the paper explores how different interpretations of the notion...... of social responsibility of science imply different forms of governance of and within science. The paper employs a Foucaldian discourse analysis to understand how a particular conceptualisation of responsibility implies a political rationality, i.e. a particular form of governance of science.

  18. Water Soluble Responsive Polymer Brushes

    Andrew J. Parnell

    2011-12-01

    Full Text Available Responsive polymer brushes possess many interesting properties that enable them to control a range of important interfacial behaviours, including adhesion, wettability, surface adsorption, friction, flow and motility. The ability to design a macromolecular response to a wide variety of external stimuli makes polymer brushes an exciting class of functional materials, and has been made possible by advances in modern controlled polymerization techniques. In this review we discuss the physics of polymer brush response along with a summary of the techniques used in their synthesis. We then review the various stimuli that can be used to switch brush conformation; temperature, solvent quality, pH and ionic strength as well as the relatively new area of electric field actuation We discuss examples of devices that utilise brush conformational change, before highlighting other potential applications of responsive brushes in real world devices.

  19. Emotional response to musical repetition.

    Livingstone, Steven R; Palmer, Caroline; Schubert, Emery

    2012-06-01

    Two experiments examined the effects of repetition on listeners' emotional response to music. Listeners heard recordings of orchestral music that contained a large section repeated twice. The music had a symmetric phrase structure (same-length phrases) in Experiment 1 and an asymmetric phrase structure (different-length phrases) in Experiment 2, hypothesized to alter the predictability of sensitivity to musical repetition. Continuous measures of arousal and valence were compared across music that contained identical repetition, variation (related), or contrasting (unrelated) structure. Listeners' emotional arousal ratings differed most for contrasting music, moderately for variations, and least for repeating musical segments. A computational model for the detection of repeated musical segments was applied to the listeners' emotional responses. The model detected the locations of phrase boundaries from the emotional responses better than from performed tempo or physical intensity in both experiments. These findings indicate the importance of repetition in listeners' emotional response to music and in the perceptual segmentation of musical structure.

    1982-06-01

    Using an automated method of calculating airways resistance in the body plethysmograph, we have investigated changes occurring immediately after inhalation of cigarette smoke. Decreases in specific conductance occurred by the time of the first measurement seven or eight seconds after exposure to single inhalations of cigarette smoke in 12 smokers and 12 non-smokers. Less than half of the initial change was present 40 seconds after the inhalation. Initial responses were greater in the non-smokers. Responses recurred with repeated inhalations in smokers and non-smokers. Prior administration of salbutamol and ipratropium bromide significantly inhibited the response and this inhibition appeared to be greater in non-smokers. Sodium cromoglycate inhaled as a dry powder had no effect on the response.

    1996-03-01

    Nurses will be key participants in health care reform as health care shifts from a hospital-based disease orientation to a community-centered health promotion focus. Nursing in communities, the environmental context of clients' everyday lives, requires attention to social, economic, and political circumstances that influence health status and access to health care. Therefore, nursing educators have the responsibility to prepare future nurses for community-based practice by instilling moral and professional practice obligations, cultural sensitivity, and other facets of social responsibility. In this article, social responsibility and journaling, a teaching/learning strategy suggested by the new paradigm approach of the curriculum revolution, are explored. A qualitative research study of more than 100 nursing student journal entries illustrates the concept of social responsibility and how it developed in a group of baccalaureate nursing students during a clinical practicum in a large urban homeless shelter.

    2006-01-01

    The gastric mucosa separates the underlying tissue from the vast array of antigens that traffic through the stomach lumen. While the extreme pH of this environment is essential in aiding the activation of enzymes and food digestion, it also renders the gastric epithelium free from bacterial colonization, with the exception of one important human pathogen, H pylori. This bacterium has developed mechanisms to survive the harsh environment of the stomach, actively move through the mucosal layer, attach to the epithelium, evade immune responses, and achieve persistent colonization. While a hallmark of this infection is a marked inflammatory response with the infiltration of various immune cells into the infected gastric mucosa, the host immune response is unable to clear the infection and may actually contribute to the associated pathogenesis. Here, we review the host responses involved during infection with H pylori and how they are influenced by this bacterium. PMID:17007009

  5. Procedure for determining the SSE response from the OBE response

    International Nuclear Information System (INIS)

    Curreri, J.

    1985-01-01

    Regulatory Guide 1.61 specifies the damping that should be used for all modes that are considered in an elastic spectral or time history dynamic seismic analysis of Seismic Category I components. Table 1 of R.G 1.61 specifies damping values for dynamic analysis for two different earthquakes, the Safe Shutdown Earthquake and the Operating Basis Earthquake. The guide specifies that ''...if the maximum stresses due to static, seismic and other dynamic loading are significantly lower than the yield stresses and 1/2 yield stress for SSE and 1/2 SSE respectively, in any structure a component damping values lower than those specified in Table 1 ....should be used .... to avoid underestimating the amplitude of vibration of dynamic stress.'' The guide requires that the appropiate damping values be used which reflect the state of stress that will be experienced by the equipment. In applying these values to the response of equipment, to an OBE and to an SSE, the selected damping should result in a dynamic response for the SSE that is greater than the response due to the OBE, all other factors being equal. The purpose of the statement in the guide is to note that at higher stress levels, the higher damping values could be used, but at lower stress levels, the lower values of damping should be used. Current procedures that are used in implementing R.G. 1.61 frequently result in an OBE response that is greater than the SSE response. This is because the higher damping under the SSE is used at all stress levels, low as well as high. This is obviously not the intent of the Regulatory Guide. A procedure has been developed which derives an expression relating the SSE response to the OBE response. Two factors are involved in the equation. The first involves the damping ratios for the SSE and OBE events and the second is the ratio between the levels of the OBE and SSE

    International Nuclear Information System (INIS)

    Samson, L.D.

    2003-01-01

    Using Affymetrix oligonucleotide GeneChip analysis, we previously found that, upon exposure to the simple alkylating agent methylmethane sulfonate, the transcript levels for about one third of the Saccharomyces cerevisiae genome (∼2,000 transcripts) are induced or repressed during the first hour or two after exposure. In order to determine whether the responsiveness of these genes has any relevance to the protection of cells against alkylating agents we have undertaken several follow-up studies. First, we explored the specificity of this global transcriptional response to MMS by measuring the global response of S. cerevisiae to a broad range of agents that are known to induce DNA damage. We found that each agent produced a very different mRNA transcript profile, even though the exposure doses produced similar levels of toxicity. We also found that the selection of genes that respond to MMS is highly dependent upon what cell cycle phase the cells are in at the time of exposure. Computational clustering analysis of the dataset derived from a large number of exposures identified several promoter motifs that are likely to control some of the regulons that comprise this large set of genes that are responsive to DNA damaging agents. However, it should be noted that these agents damage cellular components other than DNA, and that the responsiveness of each gene need not be in response to DNA damage per se. We have also begun to study the response of other organisms to alkylating agents, and these include E. coli, cultured mouse and human cells, and mice. Finally, we have developed a high throughput phenotypic screening method to interrogate the role of all non-essential S. cerevisiae genes (about 4,800) in protecting S. cerevisiae against the deleterious effects of alkylating agents; we have termed this analysis 'genomic phenotyping'. This study has uncovered a plethora of new pathways that play a role in the recovery of eukaryotic cells after exposure to toxic

    ALICE is the LHC experiment dedicated to the study of Heavy Ion collisions. In particular, the detector features low momentum tracking and vertexing, and comprehensive particle identification capabilities. In a single central heavy ion collision at the LHC, thousands of particles per unit rapidity are produced, making the data volume, track reconstruction and search of rare signals particularly challenging. Data science and machine learning techniques could help to tackle some of the challenges outlined above. In this talk, we will discuss some early attempts to use these techniques for the processing of detector signals and for the physics analysis. We will also highlight the most promising areas for the application of these methods.

    International Nuclear Information System (INIS)

    Chandrasekharan, A.R.; Paul, D.K.

    1975-01-01

    For aseismic design of structures, the ground motion data is assumed either in the form of ground acceleration as a function of time or indirectly in the form of response spectra. Though the response spectra approach has limitations like not being applicable for nonlinear problems, it is usually used for structures like nuclear power plants. Fifty accelerograms recorded at alluvial sites have been processed. Since different empirical formulas relating acceleration with magnitude and distance give a wide scatter of values, peak ground acceleration alone cannot be the parameter as is assumed by a number of authors. The spectra corresponding to 5% damping have been normalised with respect to three parameters, namely, peak ground acceleration, peak ground velocity and a nondimensional quantity ad/v 2 . Envelopee of maxima and minima as well as average response spectra has been obtained. A comparison with the USAEC spectra has been made. A relation between ground acceleration, ground velocity and ad/v 2 has been obtained which would nearly give the same magnification of the response. A design response spectra for alluvial soils has been recommended. (author)

  19. Methodology for combining dynamic responses

    International Nuclear Information System (INIS)

    Cudlin, R.; Hosford, S.; Mattu, R.; Wichman, K.

    1978-09-01

    The NRC has historically required that the structural/mechanical responses due to various accident loads and loads caused by natural phenomena, (such as earthquakes) be combined when analyzing structures, systems, and components important to safety. Several approaches to account for the potential interaction of loads resulting from accidents and natural phenomena have been used. One approach, the so-called absolute or linear summation (ABS) method, linearly adds the peak structural responses due to the individual dynamic loads. In general, the ABS method has also reflected the staff's conservative preference for the combination of dynamic load responses. A second approach, referred to as SRSS, yields a combined response equal to the square root of the sum of the squares of the peak responses due to the individual dynamic loads. The lack of a physical relationship between some of the loads has raised questions as to the proper methodology to be used in the design of nuclear power plants. An NRR Working Group was constituted to examine load combination methodologies and to develop a recommendation concerning criteria or conditions for their application. Evaluations of and recommendations on the use of the ABS and SRSS methods are provided in the report

    The dialog within aviation management education regarding ethics is incomplete without a discussion of corporate social responsibility (CSR). CSR research requires discussion involving: (a) the current emphasis on CSR in business in general and aviation specifically; (b) business and educational theory that provide a basis for aviation companies to engage in socially responsible actions; (c) techniques used by aviation and aerospace companies to fulfill this responsibility; and (d) a glimpse of teaching approaches used in university aviation management classes. The summary of this research suggests educators explain CSR theory and practice to students in industry and collegiate aviation management programs. Doing so extends the discussion of ethical behavior and matches the current high level of interest and activity within the aviation industry toward CSR.

    Abscisic acid (ABA) is one of the “classical” plant hormones, i.e. discovered at least 50 years ago, that regulates many aspects of plant growth and development. This chapter reviews our current understanding of ABA synthesis, metabolism, transport, and signal transduction, emphasizing knowledge gained from studies of Arabidopsis. A combination of genetic, molecular and biochemical studies has identified nearly all of the enzymes involved in ABA metabolism, almost 200 loci regulating ABA response, and thousands of genes regulated by ABA in various contexts. Some of these regulators are implicated in cross-talk with other developmental, environmental or hormonal signals. Specific details of the ABA signaling mechanisms vary among tissues or developmental stages; these are discussed in the context of ABA effects on seed maturation, germination, seedling growth, vegetative stress responses, stomatal regulation, pathogen response, flowering, and senescence.

    Nuclear reactor operator emergency response behavior has persisted as a training problem through lack of information. The industry needs an accurate definition of operator behavior in adverse stress conditions, and training methods which will produce the desired behavior. Newly assembled information from fifty years of research into human behavior in both high and low stress provides a more accurate definition of appropriate operator response, and supports training methods which will produce the needed control room behavior. The research indicates that operator response in emergencies is divided into two modes, conditioned behavior and knowledge based behavior. Methods which assure accurate conditioned behavior, and provide for the recovery of knowledge based behavior, are described in detail

    2003-01-01

    The data-based literature addressing children's psychological responses to hospitalization was reviewed using methods outlined by Cooper (1989). Using a developmental science perspective, early research was reviewed and a model of variables that contribute to children's responses was constructed. This model consists of three major foci, including maturational and cognitive variables (developmental level, experience, coping style), ecological variables (family and hospital milieu), and biological variables (inborn factors and pathophysiology). Coping serves as the overarching framework for examining these variables and their contributions to children's responses to hospitalization. A variety of theoretical perspectives from the social sciences have been used, with psychoanalytic and stress and adaptation theories predominating. The majority of the research used simple case study, descriptive, or pre- and post-test designs. Methodologic issues were common. Little qualitative work has been done. Future research directions call for studies to adopt new theoretical and empirical models that are methodologically rigorous and clinically relevant and that embrace the precepts of developmental science.

Using field-realistic studies, our integrative analysis aims to compare i) how molecular and physiological mechanisms related to protection, repair and energy allocation can impact...... life history traits of stressed organisms, and ii) to what extent trait responses influence individual and population responses. Common response mechanisms are evident at molecular and cellular scales but become rather difficult to define at higher levels due to evolutionary distance and environmental...

  6. Plant Responses to Nanoparticle Stress

    Directory of Open Access Journals (Sweden)

    Zahed Hossain

    2015-11-01

    Full Text Available With the rapid advancement in nanotechnology, release of nanoscale materials into the environment is inevitable. Such contamination may negatively influence the functioning of the ecosystems. Many manufactured nanoparticles (NPs contain heavy metals, which can cause soil and water contamination. Proteomic techniques have contributed substantially in understanding the molecular mechanisms of plant responses against various stresses by providing a link between gene expression and cell metabolism. As the coding regions of genome are responsible for plant adaptation to adverse conditions, protein signatures provide insights into the phytotoxicity of NPs at proteome level. This review summarizes the recent contributions of plant proteomic research to elaborate the complex molecular pathways of plant response to NPs stress.

  8. Mapping 'Social Responsibility' in Science

    2014-01-01

    This article employs the Foucauldian notion of ‘political rationality’ to map discussions and ideals about the responsibility of science toward society. By constructing and analyzing an archive of 263 journal papers, four political rationalities were identified: the Demarcation rationality, which......, which insists that responsible science should live up to public demands for innovation and democracy; and the Integration rationality, which advocates that science should be co-constructed with societal actors in order to be socially responsible. While each rationality is distinct, the article argues...... that all of them address the issue of a boundary (or integration) between science and society. Hence, it is not possible for scientists to avoid ‘a relationship’ with society. The political question is how this relationship is to be defined and regulated....

  9. Comparative immunology of allergic responses.

    Science.gov (United States)

    Gershwin, Laurel J

    2015-01-01

    Allergic responses occur in humans, rodents, non-human primates, avian species, and all of the domestic animals. These responses are mediated by immunoglobulin E (IgE) antibodies that bind to mast cells and cause release/synthesis of potent mediators. Clinical syndromes include naturally occurring asthma in humans and cats; atopic dermatitis in humans, dogs, horses, and several other species; food allergies; and anaphylactic shock. Experimental induction of asthma in mice, rats, monkeys, sheep, and cats has helped to reveal mechanisms of pathogenesis of asthma in humans. All of these species share the ability to develop a rapid and often fatal response to systemic administration of an allergen--anaphylactic shock. Genetic predisposition to development of allergic disease (atopy) has been demonstrated in humans, dogs, and horses. Application of mouse models of IgE-mediated allergic asthma has provided evidence for a role of air pollutants (ozone, diesel exhaust, environmental tobacco smoke) in enhanced sensitization to allergens.

  14. The path to corporate responsibility.

    Science.gov (United States)

    Zadek, Simon

    2004-12-01

    Nike's tagline,"Just do it," is an inspirational call to action for the millions who wear the company's athletic gear. But in terms of corporate responsibility, Nike didn't always follow its own advice. In the 1990s, protesters railed against sweatshop conditions at some of its overseas suppliers and made Nike the global poster child for corporate ethical fecklessness. The intense pressure that activists exerted on the athletic apparel giant forced it to take a long, hard look at corporate responsibility--sooner than it might have otherwise. In this article, Simon Zadek, CEO of the UK-based institute AccountAbility, describes the bumpy route Nike has traveled to get to a better ethical place, one that cultivates and champions responsible business practices. Organizations learn in unique ways, Zadek contends, but they inevitably pass through five stages of corporate responsibility, from defensive ("It's not our fault") to compliance ("We'll do only what we have to") to managerial ("It's the business") to strategic ("It gives us a competitive edge") and, finally, to civil ("We need to make sure everybody does it"). He details Nike's arduous trek through these stages-from the company's initial defensive stance, when accusations about working conditions arose, all the way to its engagement today in the international debate about business's role in society and in public policy. As he outlines this evolution, Zadek offers valuable insights to executives grappling with the challenge of managing responsible business practices. Beyond just getting their own houses in order, the author argues, companies need to stay abreast of the public's evolving ideas about corporate roles and responsibilities. Organizations that do both will engage in what he calls"civil learning".

    Anhedonia is a core negative symptom of schizophrenia. Schizophrenia patients report largely intact pleasure in consuming rewards, but have impairments in generating motivated behavior to pursue rewards, and show reduced fMRI activation of the reward pathway during presentation of rewarded stimuli. A computer based task measuring the development of a response bias in favor of rewarded stimuli permits assessment of reward-induced motivation. We hypothesized that subjects with schizophrenia would be impaired on this task. 58 schizophrenia subjects (SCZ) and 52 healthy controls (CON) were studied with a signal detection task to assess reward responsiveness. In multiple trials over three blocks subjects were asked to correctly identify two stimuli that were paired with unequal chance of monetary reward. The critical outcome variable was response bias, the development of a greater percent correct identification of the stimulus that was rewarded more often. An ANOVA on response bias with Block as a repeated-measures factor and Diagnosis as a between-group factor indicated that SCZ subjects achieved a lower bias to rewarded stimuli than CON subjects (F(1,105)=8.82, p=0.004, η 2 =0.078). Post hoc tests indicated that SCZ subjects had significantly impaired bias in Block 1 (p=0.002) and Block 2 (p=0.05), indicating that SCZ were slower to achieve normal levels of bias during the session. SCZ subjects were slower to develop response bias to rewarded stimuli than CON subjects. This finding is consonant with the hypothesis that people with schizophrenia have a blunted capacity to modify behavior in response to reward. Copyright © 2018. Published by Elsevier B.V.

  16. Shallow End Response from ATEM

    Vetrov, A.

    2014-12-01

    Different geological, hydrological, environmental and engineering targets are located shallow underground. The information collected with ATEM systems might be very useful for their study; although there are many deeper targets that the ATEM systems are traditionally used for. The idea to raise magnetic moment output and get deeper penetration response was one of the goals of ATEM systems development during the last decade. The shallow geology response was a trade for such systems, which sometimes were almost blind in the first hundred meter under surface. The possibility to achieve shallow end response from ATEM systems has become significant subject in last years. Several airborne TDEM systems got second higher frequency and lower magnetic moment signal to pick up shallow response together with deep one. Having a potential advantage such implementation raises complication and cost of the system. There's no need to receive 500 meter deep response when exploring shallow geology. P-THEM system having a compact size transmitter and relatively light weight is working on one base frequency at a time, but this frequency can be preset before a flight considering survey goals. A study of shallow geology response of the P-THEM system working on different base frequency has been conducted in 2014 in Ontario. The Alliston test area located in Southern Ontario has been flown with the P-THEM system working on base frequencies 30Hz and 90Hz. Results of the observations will be discussed in the presentation. The shallow end data can be used for mineral exploration applications and also for hydrological and environmental studies.

    This article gives details of the response to the criticism of the Special Report on Emission Scenarios (SRES) and of some aspects of IPCC assessments. The criticism claims that market exchange rates (MER) were used instead of purchasing power parities (PPP) and that scenarios using Gross Domestic Product (GDP) growth in developing regions were flawed. Points raised in the response included that scenarios of GDP growth are typically expressed as MER, that the IPCC scenarios did include PPP-based scenarios, and that long-term emissions are based on more than just economic growth

    2009-09-01

    Here we report the fabrication of magnetically responsive calcium carbonate microcrystals produced by coprecipitation of calcium carbonate in the presence of citrate-stabilized iron oxide nanoparticles. We demonstrate that the calcite microcrystals obtained possess superparamagnetic properties due to incorporated magnetite nanoparticles and can be manipulated by an external magnetic field. The microcrystals doped with magnetic nanoparticles were utilized as templates for the fabrication of hollow polyelectrolyte microcapsules, which retain the magnetic properties of the sacrificial cores and might be spatially manipulated using a permanent magnet, thus providing the magnetic-field-facilitated delivery and separation of materials templated on magnetically responsive calcite microcrystals.

    2007-09-15

    The current article aims at studying the effects of taxation on environmental quality, in an economy where its agents are responsible. Individual responsibility towards nature is modelized by the voluntary effort to which the households have agreed insofar as the improvement of environmental quality is concerned. It is an original way to show that the individuals may feel committed towards the environment and assume obligations towards it as well as towards environmental public policy. Given that, in our model, such effort is taken from one's allocated time for leisure, its opportunity cost is that of the sacrificed time for leisure, and is therefore equal to the individual's wage. We shall highlight that State intervention through the introduction of a (green) tax always crowds out individual responsibility. However, the intensity of this crowding-out depends on the performance of the State. Moreover, State intervention could, depending on the amount of crowding-out, reduce the overall quality of the environment. In a general equilibrium setting, we show that the crowding-out effect is not systematic. This is because there will then be an interaction between effort (or work time) and the cost of that effort (linked to the individual's wage, and therefore to production and finally to work/effort). In this article, we shall discuss the conditions under which public policy crowds out individual responsibility within this context. (author)

  10. Mechanisms of subliminal response priming.

    Science.gov (United States)

    Kiesel, Andrea; Kunde, Wilfried; Hoffmann, Joachim

    2008-07-15

    Subliminal response priming has been considered to operate on several stages, e.g. perceptual, central or motor stages might be affected. While primes' impact on target perception has been clearly demonstrated, semantic response priming recently has been thrown into doubt (e.g. Klinger, Burton, & Pitts, 2000). Finally, LRP studies have revealed that subliminal primes evoke motor processes. Yet, the premises for such prime-evoked motor activation are not settled. A transfer of priming to stimuli that have never been presented as targets appears particularly interesting because it suggests a level of processing that goes beyond a reactivation of previously acquired S-R links. Yet, such transfer has not always withstood empirical testing. To account for these contradictory results, we proposed a two-process model (Kunde, Kiesel, & Hoffmann, 2003): First, participants build up expectations regarding imperative stimuli for the required responses according to experience and/or instructions. Second, stimuli that match these "action triggers" directly activate the corresponding motor responses irrespective of their conscious identification. In line with these assumptions, recent studies revealed that non-target primes induce priming when they fit the current task intentions and when they are expected in the experimental setting.

  11. Apology for errors: whose responsibility?

    Science.gov (United States)

    Leape, Lucian L

    2012-01-01

    When things go wrong during a medical procedure, patients' expectations are fairly straightforward: They expect an explanation of what happened, an apology if an error was made, and assurance that something will be done to prevent it from happening to another patient. Patients have a right to full disclosure; it is also therapeutic in relieving their anxiety. But if they have been harmed by our mistake, they also need an apology to maintain trust. Apology conveys respect, mutual suffering, and responsibility. Meaningful apology requires that the patient's physician and the institution both take responsibility, show remorse, and make amends. As the patient's advocate, the physician must play the lead role. However, as custodian of the systems, the hospital has primary responsibility for the mishap, for preventing that error in the future, and for compensation. The responsibility for making all this happen rests with the CEO. The hospital must have policies and practices that ensure that every injured patient is treated the way we would want to be treated ourselves--openly, honestly, with compassion, and, when indicated, with an apology and compensation. To make that happen, hospitals need to greatly expand training of physicians and others, and develop support programs for patients and caregivers.

The optical response in the antenna feed gap is simulated as functions of its geometry parameters (flare angle, arm length, apex width, thickness, gap dimension, as well as the index of substrate), which provide a clear guideline to exploit such antenna structures in practice.

  17. Green taxation and individual responsibility

    2007-01-01

    The current article aims at studying the effects of taxation on environmental quality, in an economy where its agents are responsible. Individual responsibility towards nature is modelized by the voluntary effort to which the households have agreed insofar as the improvement of environmental quality is concerned. It is an original way to show that the individuals may feel committed towards the environment and assume obligations towards it as well as towards environmental public policy. Given that, in our model, such effort is taken from one's allocated time for leisure, its opportunity cost is that of the sacrificed time for leisure, and is therefore equal to the individual's wage. We shall highlight that State intervention through the introduction of a (green) tax always crowds out individual responsibility. However, the intensity of this crowding-out depends on the performance of the State. Moreover, State intervention could, depending on the amount of crowding-out, reduce the overall quality of the environment. In a general equilibrium setting, we show that the crowding-out effect is not systematic. This is because there will then be an interaction between effort (or work time) and the cost of that effort (linked to the individual's wage, and therefore to production and finally to work/effort). In this article, we shall discuss the conditions under which public policy crowds out individual responsibility within this context. (author)

    A sufficient mechanical response of thermoelectric materials (TEMats) to structural loadings is a prerequisite to the exploitation of any candidate TEMat's thermoelectric efficiency. If a TEMat is mechanically damaged or cracks from service-induced stresses, then its thermal and electrical functions can be compromised or even cease. Semiconductor TEMats tend to be quite brittle and have a high coefficient of thermal expansion; therefore, they can be quite susceptible to mechanical failure when subjected to operational thermal gradients. Because of this, sufficient mechanical response (vis-a-vis, mechanical properties) of any candidate TEMat must be achieved and sustained in the context of the service-induced stress state to which it is subjected. This report provides an overview of the mechanical responses of state-of-the-art TEMats; discusses the relevant properties that are associated with those responses and their measurement; and describes important, nonequilibrium phenomena that further complicate their use in thermoelectric devices. For reference purposes, the report also includes several appendixes that list published data on elastic properties and strengths of a variety of TEMats.

    Full Text Available Purpose: The purpose of this paper is to is to provide insights on implementing corporate social responsibility for sustainability (CSRS concept and show how it differs from basic corporate social responsibility (CSR. Methodology: The paper discusses major issues with references to existing literature and real business cases from S&P500 consumer discretionary sector. Findings: The main fi nding of this paper is that CSRS could provide the company with a competitive advantage as a growing number of consumers become more sustainable conscious. It could also help to overcome the increasing consumers’ skepticism towards corporate social responsibility practices. Finally, it can also be seen as a step forward in defi ning what types of corporate activities are associated with desirable social and environmental gains. Research limitations: Our sample was restricted to the U.S. fi rms from the consumer discretionary sector. Therefore, conclusions should not be generalized to other markets. Our study is based on the analysis of environmental and social responsibility statements and assumes that they accurately represent corporate commitment in majority of the cases. Practical implications: CSRS offers corporations the opportunity to use their unique skills, culture, values, resources, and management capabilities to lead social progress by making sustainability part of its internal corporate logic. Originality: The paper raises the importance of the different conditions necessary for making sustainable development concept an important part of corporate strategy.

  13. Radiological terrorism and Australia's response

    International Nuclear Information System (INIS)

    Patterson, D.

    2003-01-01

    A terrorist attack in Australia involving dispersal of radioactive material is different from conventional terrorist attacks involving explosives. The trauma experienced by victims during an explosive incident includes cuts, broken limbs, burns and shock. When an explosive device involving radioactive materials is involved, there are a number of additional characteristics including the contamination of victims and the surrounding area and the potential requirement for ongoing monitoring and decontamination. Response actions may require additional complex emergency response measures including immediate protective actions to protect those potentially exposed to contamination, mass casualty care, and public and mental health. There are concerns that terrorist organizations are showing increasing interest in acquiring radiological material that could be used with explosive. A dirty bomb or technically known as a radiological dispersal device (RDD) is a device designed to spread radioactive contamination over a wide area and pose a health and safety threat to those within the contaminated area. The radioactive material could be in the form of a large chunk of material, fine powder, a liquid mist, or a gas. The material may also be spread in other ways, such as by simply emptying a container over the desired area. As RDD's do not require large amounts of explosives, there is unlikely to be a large numbers of casualties, however the areas contaminated by the radiological material may cause immediate and long term health risks to those exposed. An RDD is a weapon of Mass Disruption rather than destruction. While the likelihood of RDD's being employed by terrorist in Australia is still considered remote, Australia's emergency response organizations are developing plans to ensure a rapid and comprehensive response occurs should such an event occur in this country, The presentation will outline Australia's response arrangements at the local/state level and the type of federal

    Full Text Available The judicial responsibility is acknowledged in the judicial doctrine2, as being ‘the starting point’ of the entire social responsibility, position that continues to have from ancient times until today, thus providing an expression of Law on its most concerted form, which reflect the stage of evolution of the entire social life. Expressing forms and realities of social life, both values and norms are ideal standards of conduct, perceived as individual requirements by each member of society3. The human action enforces the compliance of certain rules and its subordination of certain goals and interests, according to a system of principles and criteria; this is because the individual lead his existence in a relational system with others, a system characterized by extensive interactions and interdependencies. In any society may appear different types of conduct, whose broad includes those conformist, innovative, as well as those non-conformists, escapist or deviant. As full integration of the individual in society, legal norms are not an exclusive element; these are the foundation of a set of rules for the most various types. The institution of social responsibility arises precisely in this way, representing a higher level of integration of the individual in the society.

    2007-01-01

    Pandemic disease, natural disasters and terrorism can affect thousands of people in a relatively short period of time anywhere in the world. Our recent international experience with hurricanes, earthquakes, tsunamis and infectious diseases (AIDS, TB and highly pathogenic avian influenza) show us that we must respond with a coordinated approach or we will fail the very people we intend to help. Nations from around the world are often eager to send assistance to the site of a disaster, but coordinating the incoming aid is more often flawed and imprecise than it must be in order to save lives and mitigate suffering. How can any one country, suffering from a horrendous calamity coordinate the incoming aid from around the world? Can any one agency hope to coordinate the myriad nation's response let alone that of the hundreds of non-governmental organizations? Currently, the answer is sadly, no. The purpose of this presentation is not to recommend one over the many international bodies which claim to oversee humanitarian assistance; the purpose of this presentation is to discuss the elements of only one aspect of the overall response effort: public health and medical response coordination. Public health response is of course different than a purely medical response. Traditionally, in a natural disaster, immediate public health concerns center around water, sewerage/waste disposal, potential for disease outbreaks, etc, whereas medical response concentrates on triage, saving those who can be saved, patching up the injured, and to a lesser extent, primary care to the survivors. In order to avoid political controversy, this presentation will use the example of Hurricane Iniki in Hawaii, September 1992, to illustrate key concepts. The State of Hawaii is no stranger to natural disasters. Their emergency response mechanisms are well honed, exercised and quite capable. However, the local community leaders on Kauai Island went thru each of the following phases before they

  19. Saltmarsh plant responses to eutrophication.

    2016-12-01

    In saltmarsh plant communities, bottom-up pressure from nutrient enrichment is predicted to increase productivity, alter community structure, decrease biodiversity, and alter ecosystem functioning. Previous work supporting these predictions has been based largely on short-term, plot-level (e.g., 1-300 m 2 ) studies, which may miss landscape-level phenomena that drive ecosystem-level responses. We implemented an ecosystem-scale, nine-year nutrient experiment to examine how saltmarsh plants respond to simulated conditions of coastal eutrophication. Our study differed from previous saltmarsh enrichment studies in that we applied realistic concentrations of nitrate (70-100 μM NO 3 - ), the most common form of coastal nutrient enrichment, via tidal water at the ecosystem scale (~60,000 m 2 creeksheds). Our enrichments added a total of 1,700 kg N·creek -1 ·yr -1 , which increased N loading 10-fold vs. reference creeks (low-marsh, 171 g N·m -2 ·yr -1 ; high-marsh, 19 g N·m -2 ·yr -1 ). Nutrients increased the shoot mass and height of low marsh, tall Spartina alterniflora; however, declines in stem density resulted in no consistent increase in aboveground biomass. High-marsh plants S. patens and stunted S. alterniflora did not respond consistently to enrichment. Nutrient enrichment did not shift community structure, contrary to the prediction of nutrient-driven dominance of S. alterniflora and Distichlis spicata over S. patens. Our mild responses may differ from the results of previous studies for a number of reasons. First, the limited response of the high marsh may be explained by loading rates orders of magnitude lower than previous work. Low loading rates in the high marsh reflect infrequent inundation, arguing that inundation patterns must be considered when predicting responses to estuarine eutrophication. Additionally, we applied nitrate instead of the typically used ammonium, which is energetically favored over nitrate for plant uptake. Thus, the

    Full Text Available This prospective, cross-sectional, interventional study was designed to determine the association between the hormones of the pituitary-adrenal and pituitary-thyroid axes and other clinical parameters with the blood glucose perturbations in dogs with naturally occurring Babesia canis rossi babesiosis. Thirty-six dogs with canine babesiosis were studied. Blood samples were obtained from the jugular vein in each dog prior to treatment at admission to hospital and serum endogenous adrenocorticotrophic hormone(ACTH, pre-ACTH cortisol, thyroxine, free thyroxine and TSH concentrations were measured. Immediately thereafter each dog was injected intravenously with 5 µg/kg of ACTH (tetracosactrin. A 2nd blood sample was taken 1 hour later for serumpost-ACTHcortisol measurement. Three patient groups were recruited: hypoglycaemic dogs (glucose 5.5 mmol/ℓ, n = 12. Basal and post-ACTH serum cortisol concentrations were significantly higher in hypoglycaemic dogs, whereas body temperature, serum thyroxine and free thyroxine were significantly lower in hypoglycaemic dogs. Haematocrit was significantly lower in both hypo-and hyperglycaemic dogs compared with normoglycaemic dogs. Low blood glucose concentrations were significantly associated with high basal and post-ACTH cortisol concentrations and with low serum thyroxine and free thyroxine concentrations in dogs suffering from B. canis rossi babesiosis.

    1999-01-01

    The nuclear collective response is investigated in the framework of a doorway picture in which the spreading width of the collective emotion is described as a coupling to more and more complex configurations. It is shown that this coupling induces fluctuations of the observed strength. In the case of a hierarchy of overlapping decay channels, Ericson fluctuations are observed at different scales. Methods for extracting these scales and the related lifetimes are discussed. Finally, it is shown that the coupling of different states at one level of complexity to some common decay channels at the next level, may produce interference-like patterns in the nuclear response. This quantum effect leads to anew type of fluctuations with a typical width related to the level spacing. (author)

The phenomena that contribute to the frequency response of an electrode include: (1) double layer capacitance; (2) Faradaic reaction resistance; (3) mass transfer of Warburg impedance; and (4) ohmic solution resistance. Nickel cadmium cells were investigated in solutions of KOH. A significant amount of data was acquired. Quantitative data analysis, using the developed software, is planned for the future.

    Gaganidze, E; Ziese, M

    2000-01-01

    The resonance frequency of vibrating ferromagnetic reeds in a homogeneous magnetic field can be substantially modified by intrinsic and extrinsic field-related contributions. Searching for the physical reasons of the field-induced resonance frequency change and to study the influence of the spin glass state on it, we have measured the low-temperature magnetoelastic behavior and the dynamical response of vibrating amorphous and polycrystalline ferromagnetic ribbons. We show that the magnetoelastic properties depend strongly on the direction of the applied magnetic field. The influence of the re-entrant spin glass transition on these properties is discussed. We present clear experimental evidence that for applied fields perpendicular to the main area of the samples the behavior of ferromagnetic reeds is rather independent of the material composition and magnetic state, exhibiting a large decrease of the resonance frequency. This effect can be very well explained with a model based on the dynamical response of t...

    1992-01-01

    It has been suggested that planting trees could help slow the buildup of carbon dioxide in the atmosphere. Since elevated levels of CO 2 are known to enhance photosynthesis and growth in many plants, it is possible that trees could become progressively more effective in storing carbon as atmospheric CO 2 increases. However, early results from experiments with ponderosa and loblolly pines indicate that the relationship between tree growth and rising CO 2 concentrations may be more complex than scientists once thought. In these experiments, the response to elevated CO 2 has been highly dependent both on species and on mineral nutrient levels in the soil. Further work is necessary to clarify the mechanisms involved. This research will ultimately contribute to an integrated model for predicting forest ecosystem response to elevated CO 2

    2013-01-01

    Sufferers from neurologic and psychiatric disorders are not uncommonly defendants in criminal trials. This chapter surveys a variety of different ways in which neurologic disorder bears on criminal responsibility. It discusses the way in which a neurologic disorder might bear on the questions of whether or not the defendant acted voluntarily; whether or not he or she was in the mental state that is required for guilt for the crime; and whether or not he or she is deserving of an insanity defense. The discussion demonstrates that a just determination of whether a sufferer from a neurologic disorder is diminished in his or her criminal responsibility for harmful conduct requires equal appreciation of the nature of the relevant disorder and its impact on behavior, on the one hand, and of the legal import of facts about the psychologic mechanisms through which behavior is generated, on the other. © 2013 Elsevier B.V.

    2017-12-01

    Full Text Available Taxes have become an issue of corporate social responsibility (CSR, but the role of taxation is to some extent an ambiguous and controversial issue in the CSR framework. Similarly, another unclear question is what role investors who are committed to sustainable and responsible investment (SRI see taxes as having on their environmental, social, and governance (ESG agenda. Corporate taxes have an inverse relationship with the return of the investors: taxes paid directly affect what is left on the bottom line, reducing the return of investors. However, investors are now more aware of tax-related risks, which can include different forms of reputation risk. Corporate tax planning may increase the returns, but those increased returns are riskier. This study focuses particularly on the relationship between SRI and taxation. We find that tax matters are considered to be on the ESG agenda, but their role and significance in the ESG analysis is unclear.

    Advances in patient-specific information and biotechnology have contributed to a new era of computational medicine. Radiogenomics has emerged as a new field that investigates the role of genetics in treatment response to radiation therapy. Radiation oncology is currently attempting to embrace these recent advances and add to its rich history by maintaining its prominent role as a quantitative leader in oncologic response modeling. Here, we provide an overview of radiogenomics starting with genotyping, data aggregation, and application of different modeling approaches based on modifying traditional radiobiological methods or application of advanced machine learning techniques. We highlight the current status and potential for this new field to reshape the landscape of outcome modeling in radiotherapy and drive future advances in computational oncology.

    2017-08-01

    How to convert the weak chiral-interaction into the macroscopic properties of materials remains a huge challenge. Here, this study develops highly fluorescent, selectively chiral-responsive liquid quantum dots (liquid QDs) based on the hydrophobic interaction between the chiral chains and the oleic acid-stabilized QDs, which have been designated as (S)-1810-QDs. The fluorescence spectrum and liquidity of thermal control demonstrate the fluorescence properties and the fluidic behavior of (S)-1810-QDs in the solvent-free state. Especially, (S)-1810-QDs exhibit a highly chiral-selective response toward (1R, 2S)-2-amino-1,2-diphenyl ethanol. It is anticipated that this study will facilitate the construction of smart chiral fluidic sensors. More importantly, (S)-1810-QDs can become an attractive material for chiral separation. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  16. Managing an oil spill response

    Merlin, W.F.; Gorell, F.R.

    1994-01-01

    In the oil spill response business everything starts with a plan. When planning is set at only middle and top management levels before being chiseled into corporate marble, the result is all too often a plan for failure. For any chance at success, the plan must make sense to, and solve the problems of, the people at the ''business'' end of the business. In the case of Marine Spill Response Corporation (MSRC), that means highly trained responders are put at sea or along coastlines to remove oil from the water, or to deflect oil away from environmentally sensitive areas. They are fortunate in MSRC, and especially in the Gulf Coast Region, to have on their staff, some of the most knowledgeable and experienced oil spill responders in the world. The company relies on them to help build their plans, and to poke holes wherever their plans are inconsistent with getting the job done right

    2015-12-01

    Full Text Available In the world today the need for improvement the business management quality assumes significant change in organization and mode of business management. Establishing of appropriate level, structure and authority of business management depends in most cases on the size, number of employees, complexness of technological and business process, market position and other factors. Development of a business requires decentralization of operative functions. The decentralization of a business means the increase of operative activities control of greater number of managers in such a business. An important segment that so far was neither sufficiently applied in the romanian practice, not sufficiently treated is a system of responsibility. One of the aims of this research is also stimulation of more intensive activities on initiating the process of accounting modernisation. First of all, on the improvement and more rational legal accounting regulation and motivation of professional accountants organization for quicker development of contemporary accounting principles and standards in compliance with tendencies of the european environment. The known experiences just point to the necessity of more complex perception of place and role of the management accounting and within it of the system of accounting responsibility in preparing of business plans and buget, in creation of development and investment policy. Therefore, the system of accounting responsibility should eneble monitoring and control of actual operational activities of each part of decentralized business. The process of performance evaluation and accounting responsibility in a descentralized business organization represents a significant element of an internal control system and in that sense the emphasis was put on that fact in this paper.

    Overconfidence is a well-established behavioral phenomenon that involves an overestimation of own capabilities. We introduce a model, in which managers and agents exert effort in a joint production, after the manager decides on the allocation of the tasks. A rational manager tends to delegate the critical task to the agent more often than given by the efficient task allocation. In contrast, an overconfident manager is more likely to hoard responsibility, i.e. to delegate the critical task les...

  5. Phenomenology between Pathos and Response

    Directory of Open Access Journals (Sweden)

    Bernhard Waldenfels

    2011-03-01

    Full Text Available The author calls phenomenological intentionality, into question while taking it, nevertheless, as a starting point. From the analysis of the meaning of phenomena he goes back to a pathic dimension which precedes them. What happens to us or affects us and to what we respond in different ways cannot be reduced to previous horizons. Between pathos and response, there is an irreducible cleft which constitutes a special sort of time-lag. What happens to us comes is always too early; our responses always come too late. Our experience is never completely up to date. In order to explore this pre-semantic and pre-pragmatic depth of experience we need a sort of responsive reduction, which guides all meaning toward something we respond to. In conclusion, the author evokes some areas in which such a revision of phenomenology shows its effects, namely the genesis of life in bioethics, the historical elaboration of memory and the experience of the Other.  

  6. Plant responses to water stress

    Kar, Rup Kumar

    2011-01-01

    Terrestrial plants most often encounter drought stress because of erratic rainfall which has become compounded due to present climatic changes.Responses of plants to water stress may be assigned as either injurious change or tolerance index. One of the primary and cardinal changes in response to drought stress is the generation of reactive oxygen species (ROS), which is being considered as the cause of cellular damage. However, recently a signaling role of such ROS in triggering the ROS scavenging system that may confer protection or tolerance against stress is emerging. Such scavenging system consists of antioxidant enzymes like SOD, catalase and peroxidases, and antioxidant compounds like ascorbate, reduced glutathione; a balance between ROS generation and scavenging ultimately determines the oxidative load. As revealed in case of defence against pathogen, signaling via ROS is initiated by NADPH oxidase-catalyzed superoxide generation in the apoplastic space (cell wall) followed by conversion to hydrogen peroxide by the activity of cell wall-localized SOD. Wall peroxidase may also play role in ROS generation for signaling. Hydrogen peroxide may use Ca2+ and MAPK pathway as downstream signaling cascade. Plant hormones associated with stress responses like ABA and ethylene play their role possibly via a cross talk with ROS towards stress tolerance, thus projecting a dual role of ROS under drought stress.

  7. The Science of Climate Responsibility

    Mitchell, D.; Frumhoff, P. C.; Sparrow, S.; Allen, M. R.

    2015-12-01

    Extreme events linked with human induced climate change have now been reported around the globe. Among the most troublesome impacts are increased wild fires, failed crop yields, extreme flooding and increase human mortality (Hansen and Cramer, 2015). Many of these impacts are predicted to increase into the future. Non-industrialised communities around the world will be the least capable of adapting, while the industrial communities, who are often responsible for historical carbon emissions, will find adaptation easier. Such a situation lends itself to the issue of responsibility. In order to assess responsibility, it must first be established where the major carbon and methane emissions are originating. It must then be estimated how these emissions project onto localised climate, which is often the primary indicator behind impacts on society. In this study, we address this question using a 25 km regional climate model capable of simulating climate thousands of times under the Weather@home citizen science project. The use of this framework allows us to generate huge data sample sizes, which can be put in the context of very low sample sizes of observational data. We concentrate on the 2003 heat wave over Europe, but show how this method could be applied to less data rich regions, including the Middle East and the Horn of Africa.

    2011-11-01

    Advances in communications and control technology, the strengthening of the Internet, and the growing appreciation of the urgency to reduce demand side energy use are motivating the development of improvements in both energy efficiency and demand response (DR) systems in buildings. This paper provides a framework linking continuous energy management and continuous communications for automated demand response (Auto-DR) in various times scales. We provide a set of concepts for monitoring and controls linked to standards and procedures such as Open Automation Demand Response Communication Standards (OpenADR). Basic building energy science and control issues in this approach begin with key building components, systems, end-uses and whole building energy performance metrics. The paper presents a framework about when energy is used, levels of services by energy using systems, granularity of control, and speed of telemetry. DR, when defined as a discrete event, requires a different set of building service levels than daily operations. We provide examples of lessons from DR case studies and links to energy efficiency.

  9. University crisis and social responsibility

    Full Text Available The purpose of this study was to investigate the repercussion of the recent crisis of the university on its mission and responsibility and, from this reflection, to propose ways for the consolidation of this responsibility. The three main crisis faced by the university  from the middle of the XXth century identified by Boaventura Souza Santos as crisis of hegemony, of legitimacy and institutional, constituted the framework of discussion of the problem of social responsibility of the university. Although true for the universities of the advanced countries, the loss of hegemony in the area of research still does not occur in Brazilian university. To overcome the crisis of legitimacy, the creation of advanced academic and professional training institutions for the cultivation of the intellectual and professional elite of the country, as well as of non university institutions of mass higher education for the cultural and technological formation of the youth is justified. To make possible the access to these institutions by discriminated socioeconomic segments of society, the adoption of the policy of affirmative action in the form of quotas is justified.  The overcoming of the institutional crisis will be achieved when the State respect the specificity of the universities and when the evaluation criteria of her functions be adequate to her specific nature and the titularity of the evaluation belong to the institutions themselves assuring the external evaluation by effective pairs and not by pairs coopted by the State.

  10. Responsibilities of Companies towards Employees

    Directory of Open Access Journals (Sweden)

    Monray Marsellus Botha

    2015-07-01

    Full Text Available Central to company law is the promotion of corporate governance. An important question in company law still today is in whose interest the company should be managed. Corporate governance needs to address the entire span of responsibilities to stakeholders of the company such as customers, employees, shareholders, suppliers and the community at large. The promotion of human rights in the application of company law must also take place. This is extremely important given the significant role of enterprises within the social and economic life of the nation. The interests of various stakeholder groups in the context of the corporation as a "social institution" should be enhanced and protected. Because corporations are part of society and the community, like all of us, it is required of them to be socially responsible and have greater accountability to all stakeholders of the company. Although directors must act in the best interests of shareholders collectively they must also consider the interests of other stakeholders. Sustainable relationships with all the relevant stakeholders are thus important. The advancement of social justice is thus important to corporations in that they should take note of the Constitution, labour legislation and company law legislation when social justice issues are dealt with. Employees have become very important stakeholders of companies and their needs should be taken into account in the bigger corporate governance and social responsibility framework.

  11. Hypnosis and the allergic response.

    Science.gov (United States)

    Wyler-Harper, J; Bircher, A J; Langewitz, W; Kiss, A

    1994-01-01

    In recent years our knowledge of the immune system and the pathogenesis of immune disorders has increased. There has been much research on the complex connections between the psyche, the central nervous system and the immune system and the effect of mood on disease processes. This paper reviews the evidence on the effects of hypnosis on the allergic skin test reaction, on allergies, particularly respiratory allergies and hayfever, and on bronchial hyperreactivity and asthma. Hypnosis, which is generally regarded as an altered state of consciousness associated with concentration, relaxation and imagination, and amongst other characteristics an enhanced responsiveness to suggestion, has long been thought to be effective in the amelioration of various bodily disorders. It has seemed that the state of hypnosis is capable of a bridging or mediating function in the supposed dualism between mind and body. There has been great variation in the experimental and clinical procedures such as type of hypnotic intervention employed, the training of subjects and the timing of the intervention. Also, variability in the type of allergen used and its mode of application is evident. But despite these limitations, many of the studies have shown a link between the use of hypnosis and a changed response to an allergic stimulus or to a lessened bronchial hyperreactivity. There is as yet no clear explanation for the effectiveness of hypnosis, but there is some evidence for an influence on the neurovascular component of the allergic response.

Responsibilities and ethics is where organizations on bothsides would take on and accept their own norms, tasks, obligations and be aware that in a relationship there is a need to give explanations and justify one’s actions, such partnerships will be long and prosperous. This requires a great deal of knowledge and maturity together with a very important personal characteristic that is care. This study examines whether the creation of long term partnerships through responsible and more personal (friendlyrelations brings the organization to greater success.Purpose: The purpose of this research is to determine how important it is for organizations in the tourism industry to build long term relationships, what it should be based on and whether companies are willing to change the current methods of operations.Method: The method of research was an interview with individuals that had a certain position within a tourism company and had contacts with partners and were obligated to see out new ones. A paradigm model was built and the responses analysed.Results: The survey results are encouraging. The interviews showed that respondents were aware that it is necessary to have long term and responsible partnerships.

  19. Radiosensitivity of antibody responses and radioresistant secondary tetanus antitoxin responses

    International Nuclear Information System (INIS)

    Stoner, R.; Terres, G.; Cottier, H.; Hess, M.

    1976-01-01

    Primary tetanus antitoxin responses were increasingly repressed in mice when gamma radiation doses of 100 to 400 rads were delivered by whole-body exposure prior to immunization with fluid tetanus toxoid (FTT). Nearly normal secondary antitoxin responses were obtained in mice exposed to 600 rads of gamma radiation 4 days after secondary antigenic stimulation with FTT. A rapid transition from radiosensitivity of the antibody-forming system on days 1 to 3 was followed by relative radioresistance on day 4 after the booster injection of toxoid. Studies on lymphoid cellular kinetics in popliteal lymph nodes after injection of 3 H--thymidine ( 3 H--TdR) and incorporation of 3 H--L-histidine into circulating antitoxin were carried out. Analysis of tritium radioactivity in antigen--antibody precipitates of serums 2 hr after injection of the labeled amino acid revealed maximum incorporation into antibody around day 7 after the booster in nonirradiated controls and about day 12, i.e., 8 days after irradiation, in experimental mice. The shift from radiosensitivity to relative radioresistance was attributed to a marked peak of plasma-cell proliferation in the medulla of lymph nodes on day 3. Many medullary plasma cells survived and continued to proliferate after exposure to radiation. Germinal centers were destroyed by radiation within 1 day. Since antibody formation continued after exposure to radiation and after the loss of germinal centers, this supports the view that germinal-center cells were involved more in the generation of memory cells than in antibody synthesis

  20. Cell-type-specific responses of RT4 neural cell lines to dibutyryl-cAMP: branch determination versus maturation

    International Nuclear Information System (INIS)

    Droms, K.; Sueoka, N.

    1987-01-01

    This report describes the induction of cell-type-specific maturation, by dibutyryl-cAMP and testololactone, of neuronal and glial properties in a family of cell lines derived from a rat peripheral neurotumor, RT4. This maturation allows further understanding of the process of determination because of the close lineage relationship between the cell types of the RT4 family. The RT4 family is characterized by the spontaneous conversion of one of the cell types, RT4-AC (stem-cell type), to any of three derivative cell types, RT4-B, RT4-D, or RT4-E, with a frequency of about 10(-5). The RT4-AC cells express some properties characteristic of both neuronal and glial cells. Of these neural properties expressed by RT4-AC cells, only the neuronal properties are expressed by the RT4-B and RT4-E cells, and only the glial properties are expressed by the RT4-D cells. This in vitro cell-type conversion of RT4-AC to three derivative cell types is a branch point for the coordinate regulation of several properties and seems to resemble determination in vivo. In our standard culture conditions, several other neuronal and glial properties are not expressed by these cell types. However, addition of dibutyryl-cAMP induces expression of additional properties, in a cell-type-specific manner: formation of long cellular processes in the RT4-B8 and RT4-E5 cell lines and expression of high-affinity uptake of gamma-aminobutyric acid, by a glial-cell-specific mechanism, in the RT4-D6-2 cell line. These new properties are maximally expressed 2-3 days after addition of dibutyryl-cAMP

  1. Theory of orbital magnetoelectric response

    International Nuclear Information System (INIS)

    Malashevich, Andrei; Souza, Ivo; Coh, Sinisa; Vanderbilt, David

    2010-01-01

    We extend the recently developed theory of bulk orbital magnetization to finite electric fields, and use it to calculate the orbital magnetoelectric (ME) response of periodic insulators. Working in the independent-particle framework, we find that the finite-field orbital magnetization can be written as a sum of three gauge-invariant contributions, one of which has no counterpart at zero field. The extra contribution is collinear with and explicitly dependent on the electric field. The expression for the orbital magnetization is suitable for first-principles implementations, allowing one to calculate the ME response coefficients by numerical differentiation. Alternatively, perturbation-theory techniques may be used, and for that purpose we derive an expression directly for the linear ME tensor by taking the first field-derivative analytically. Two types of terms are obtained. One, the 'Chern-Simons' term, depends only on the unperturbed occupied orbitals and is purely isotropic. The other, 'Kubo' terms, involve the first-order change in the orbitals and give isotropic as well as anisotropic contributions to the response. In ordinary ME insulators all terms are generally present, while in strong Z 2 topological insulators only the Chern-Simons term is allowed, and is quantized. In order to validate the theory, we have calculated under periodic boundary conditions the linear ME susceptibility for a 3D tight-binding model of an ordinary ME insulator, using both the finite-field and perturbation-theory expressions. The results are in excellent agreement with calculations on bounded samples.

    Accident or medical emergencies, both minor and critical, occurs each day and can happen in any workplace. In any medical emergencies, time is a critical factor because the first person to arrive at the scene of an accident has a key role in the rescue of a victim. With the knowledge of some common medical procedures and emergency actions, this first responder can make a positive contribution to the welfare of the accident victim. In some cases, this contribution can make difference between life and death. Improper response to medical emergencies by an untrained person can result in worsen injuries or death. Therefore, first aids training are necessary to provide the information. (author)

    When we say "medical ethics" we understand the responsibility of the physician for his medical education and his attitude to his patient. But Hippocrates is known to have said that the efficiency and good results of the treatment depends not only on the physician but on the patient and his engagement, his observance of the doctors' advice, his attitude to his own psyche and body, both in health as in illness. This is an ethical problem known to every practitioner, the problem of ethics of the patient, which ought to be more widely disseminated in society.

    Full Text Available In this article the authors aim to create a presentation of the triangle morals-ethics-responsibility with an accent on the current globalized society. Business ethics has to disseminate in all the corners of a company, and first of all it has to be understood. Understanding the moral criteria of behaviour in business is important because the new Organizational structures create new complications, related to information flow and information administration inside various workgroups and in the entire organization, for which there are no traditional precedents.

    Full Text Available Advertising, which stems from the strategic planning of the company's marketing , integrates the proposal and the corresponding consumer contract to the product or service offered to the market. As part of the contract, advertising and communication strategies and business marketing also undergo fully the principle of information and the principle of good faith in its objective meaning. Therefore, communication strategies, marketing planning and advertising actions of truly citizen and responsible company should be structured legally in order to consider all related duties in good faith.

  10. Extreme Response for Wind Turbines

    2009-01-01

    The characteristic load on wind turbines during operation are among others dependent on the mean wind speed, the turbulence intensity and type and settings of the control system. The characteristic load during operation is normally estimated by statistical extrapolation of a limited number...... of simulated 10min time series of the response according to the wind turbine standard IEC 61400-1. However, this method assumes that the individual 10min time series and the extracted peaks from the time series are independent. In the present paper is this assumption investigated based on field measurements...

  11. Responses of photoreceptors in Hermissenda.

    Akon, D L; Fuortes, M G

    1972-12-01

    The five photoreceptors in the eye of the mollusc Hermissenda crassicornis respond to light with depolarization and firing of impulses. The impulses of any one cell inhibit other cells, but the degree of inhibition differs in different pairs. Evidence is presented to show that the interactions occur at terminal branches of the photoreceptor axons, inside the cerebropleural ganglion. Properties of the generator potential are examined and it is shown that the depolarization develops in two phases which are affected differently by extrinsic currents. Finally, it is shown that by enhancing the differences in the responses of individual cells to a variety of stimuli, the interactions may facilitate a number of simple discriminations.

    1991-01-01

    A response matrix for use in core calculations for nuclear reactors with hexagonal fuel assemblies is presented. It is based on the incoming currents averaged over the half-surface of a hexagonal node by applying symmetry theory. The boundary conditions of the incoming currents on the half-surface of the node are expressed by a complete set of orthogonal vectors which are constructed from symmetrized functions. The expansion coefficients of the functions are determined by the boundary conditions of incoming currents. (author)

    2014-03-01

    The following piece is a response to the critiques from Frank, Garson, and Odenbaugh. The issues at stake are: the definition of biodiversity and its normativity, historical fidelity in ecological restoration, naturalism in environmental ethics, and the role of decision theory. The normativity of the concept of biodiversity in conservation biology is defended. Historical fidelity is criticized as an operative goal for ecological restoration. It is pointed out that the analysis requires only minimal assumptions about ethics. Decision theory is presented as a tool, not a domain-limiting necessary requirement for environmental philosophy.

    2010-01-01

    Scientific progress depends on the free dissemination of original thinking and research. With the evidence base formed by publication, investigators develop and implement additional studies, and policy makers propose new laws and regulations. The ramifications of this evidence can affect millions of lives and reallocate considerable resources for programmes or research. As such, it is incumbent on investigators to conduct rigorous research, which precludes engaging in scientific misconduct such as falsification, fabrication and plagiarism. This article addresses the causes and consequences of plagiarism and the processes by which plagiarism is discovered. It concludes by considering the responsibilities of members of the research community in preventing and addressing plagiarism.

    A sophisticated emergency response system was developed to aid in the evaluation of accidental releases of hazardous materials from the Savannah River Plant to the environment. A minicomputer system collects and archives data from both onsite meteorological towers and the National Weather Service. In the event of an accidental release, the computer rapidly calculates the trajectory and dispersion of pollutants in the atmosphere. Computer codes have been developed which provide a graphic display of predicted concentration profiles downwind from the source, as functions of time and distance

    2016-01-01

    Social responsibility is an essential part of the responsible conduct of research that presents difficult ethical questions for scientists. Recognizing one's social responsibilities as a scientist is an important first step toward exercising social responsibility, but it is only the beginning, since scientists may confront difficult value questions when deciding how to act responsibly. Ethical dilemmas related to socially responsible science fall into at least three basic categories: 1) dilemmas related to problem selection, 2) dilemmas related to publication and data sharing, and 3) dilemmas related to engaging society. In responding to these dilemmas, scientists must decide how to balance their social responsibilities against other professional commitments and how to avoid compromising their objectivity. In this article, we will examine the philosophical and ethical basis of social responsibility in science, discuss some of the ethical dilemmas related to exercising social responsibility, and make five recommendations to help scientists deal with these issues.

    1986-03-01

    Severe and widespread drought occurred over a large portion of the United States between 1974 and 1977. Impacts on agriculture and other industries, as well as local water supplies, were substantial. The federal government responded with forty assistance programs administered by sixteen federal agencies. Assistance was provided primarily in the form of loans and grants to people, businesses and governments experiencing hardship caused by drought. The total cost of the program is estimated at $7-8 billion.Federal response to the mid-1970s drought was largely untimely, ineffective and poorly coordinated. Four recommendations are offered that, if implemented, would improve future drought assessment and response efforts: 1) reliable and timely informational products and dissemination plans; 2) improved impact assessment techniques, especially in the agricultural sector, for use by government to identify periods of enhanced risk and to trigger assistance measures; 3) administratively centralized drought declaration procedures that are well publicized and consistently applied; and 4) standby assistance measures that encourage appropriate levels of risk management by producers and that are equitable, consistent and predictable. The development of a national drought plan that incorporates these four items is recommended. Atmospheric scientists have an important role to play in the collection and interpretation of near-real time weather data for use by government decision makers.

    Full Text Available Islet cell transplantation is a promising beta cell replacement therapy for patients with brittle type 1 diabetes as well as refractory chronic pancreatitis. Despite the vast advancements made in this field, challenges still remain in achieving high frequency and long-term successful transplant outcomes. Here we review recent advances in understanding the role of inflammation in islet transplantation and development of strategies to prevent damage to islets from inflammation. The inflammatory response associated with islets has been recognized as the primary cause of early damage to islets and graft loss after transplantation. Details on cell signaling pathways in islets triggered by cytokines and harmful inflammatory events during pancreas procurement, pancreas preservation, islet isolation, and islet infusion are presented. Robust control of pre- and peritransplant islet inflammation could improve posttransplant islet survival and in turn enhance the benefits of islet cell transplantation for patients who are insulin dependent. We discuss several potent anti-inflammatory strategies that show promise for improving islet engraftment. Further understanding of molecular mechanisms involved in the inflammatory response will provide the basis for developing potent therapeutic strategies for enhancing the quality and success of islet transplantation.

    Metaphors are not just decorative rhetorical devices that make speech pretty. They are fundamental tools for thinking about the world and acting on the world. The language we use to make a better world matters; words matter; metaphors matter. Words have consequences - ethical, social and legal ones, as well as political and economic ones. They need to be used 'responsibly'. They also need to be studied carefully - this is what we want to do through this editorial and the related thematic collection. In the context of synthetic biology, natural and social scientists have become increasingly interested in metaphors, a wave of interest that we want to exploit and amplify. We want to build on emerging articles and books on synthetic biology, metaphors of life and the ethical and moral implications of such metaphors. This editorial provides a brief introduction to synthetic biology and responsible innovation, as well as a comprehensive review of literature on the social, cultural and ethical impacts of metaphor use in genomics and synthetic biology. Our aim is to stimulate an interdisciplinary and international discussion on the impact that metaphors can have on science, policy and publics in the context of synthetic biology.

  3. Demand Response Valuation Frameworks Paper

    Energy Technology Data Exchange (ETDEWEB)

    Heffner, Grayson

    2009-02-01

    While there is general agreement that demand response (DR) is a valued component in a utility resource plan, there is a lack of consensus regarding how to value DR. Establishing the value of DR is a prerequisite to determining how much and what types of DR should be implemented, to which customers DR should be targeted, and a key determinant that drives the development of economically viable DR consumer technology. Most approaches for quantifying the value of DR focus on changes in utility system revenue requirements based on resource plans with and without DR. This ''utility centric'' approach does not assign any value to DR impacts that lower energy and capacity prices, improve reliability, lower system and network operating costs, produce better air quality, and provide improved customer choice and control. Proper valuation of these benefits requires a different basis for monetization. The review concludes that no single methodology today adequately captures the wide range of benefits and value potentially attributed to DR. To provide a more comprehensive valuation approach, current methods such as the Standard Practice Method (SPM) will most likely have to be supplemented with one or more alternative benefit-valuation approaches. This report provides an updated perspective on the DR valuation framework. It includes an introduction and four chapters that address the key elements of demand response valuation, a comprehensive literature review, and specific research recommendations.

  4. Responsive Polymers for Crop Protection

    Full Text Available This review outlines the responsive polymer methods currently in use with their potential application to plant protection and puts forward plant-specific mechanisms as stimuli in newly devised methods for smart release of crop protection agents (CPAs. CPAs include chemicals (fungicides, insecticides, herbicides, biochemicals (antibiotics, RNA-based vaccines for plant viruses, semiochemicals (pheromones, repellents, allomones, microbial pesticides, growth regulators (insect and plant or micronutrients, all with crop protection effects. This appraisal focuses on emerging uses of polymer nano-encapsulated CPAs. Firstly, the most interesting advances in controlled release methods are critically discussed with their advantages and drawbacks. Secondly, several plant-specific stimuli-based smart methods are anticipated for use alongside the polymer nano- or micro-capsules. These new CPA release methods are designed to (i protect plants against infection produced by fungi or bacteria, and (ii apply micro-nutrients when the plants need it the most. Thus, we foresee (i the responsive release of nano- encapsulated bio-insecticides regulated by plant stress enzymes, and (ii the delivery of micro-nutrients synchronized by the nature or intensity of plant root exudates. Such continued advances of nano-scale smart polymer-based CPAs for the protection of crops herald a “small revolution” for the benefit of sustainable agriculture.

    Full Text Available The article analyses Pakistan’s newspapers’ performance with regard to civil society in2003 by using content analysis approach. There is no gainsaying that a strong civil society guaranteesa strong democracy. In Pakistan, spells of military rule have stunted the growth of democracy,adversely affecting civil society. Media too has suffered as a result. Normative theories of media callfor laying down norms and conventions for media. In democracy, all sections of society should berepresented in media. In Pakistan’s case, due to military regimes and quasi democratic governments,combined with the demands of market economy, the media have largely not been able to fulfill thisresponsibility towards society. Social Responsibility demands that the media must fulfill itsresponsibility towards society, while giving a free space to all voices of society. In Pakistan, whethernewspapers played that role in 2003 when civil society had accelerated its campaign to end honorkillings and crimes against women is investigated. The findings show that newspapers did supportcivil society, showing a gradual movement towards a more responsible press.

  6. Groundwater response to heavy precipitation

    An investigation of the groundwater response to heavy rainfall at Lucas Heights Science and Technology Centre (LHSTC) is required under the conditions of Facility Licence F0001 for the ANSTO's Replacement Research Reactor. Groundwater continuous hydrograph monitoring has been used for this purpose. Hydrograph data from four boreholes are presented showing the rainfall recorded during the same period for comparison. The drought conditions have provided only limited cases where groundwater responded to a rainfall event. The characteristic response was local, caused by saturated soil contributing water directly to the borehole and the falling head as the water was redistributed into he aquifer in a few hours. Hydrograph data from borehole near the head of a gully showed that groundwater flow from the plateau to the gully produced a peak a fe days after the rainfall event and that the water level returned to its original level after about 10 days. The hydrograph data are consistent with an imperfect multi-layer groundwater flow regime, developed from earlier seismic and geophysical data, with decreasing rate of flow in each layer due to decreasing hydraulic conductivity with depth. The contrast in hydraulic conductivity between the thin permeable soil layer and the low permeable sandstone forms an effective barrier to vertical flow

    This technical paper presents the results of biomechanical testing conducted on the ES-2 dummy by the Occupant Safety Research Partnership and Transport Canada. The ES-2 is a production dummy, based on the EuroSID-1 dummy, that was modified to further improve testing capabilities as recommended by users of the EuroSID-1 dummy. Biomechanical response data were obtained by completing a series of drop, pendulum, and sled tests that are outlined in the International Organization of Standardization Technical Report 9790 that describes biofidelity requirements for the midsize adult male side impact dummy. A few of the biofidelity tests were conducted on both sides of the dummy to evaluate the symmetry of its responses. Full vehicle crash tests were conducted to verify if the changes in the EuroSID-1, resulting in the ES-2 design, did improve the dummy's testing capability. In addition to the biofidelity testing, the ES-2 dummy repeatability, reproducibility and durability are discussed. Finally, this technical paper will compare the biofidelity ratings of the current adult side impact dummies with the ES-2 dummy, which received an overall dummy biofidelity rating of 4.6.

    1988-01-01

    In the decade since the accident at Three Mile Island, emergency planning for response to these events has undergone a significant change in Pennsylvania, as elsewhere. Changes respond to federal guidance and to state agency initiatives. The most singular change is the practice of implementing a protective action throughout the entire emergency planning zone (EPZ). Due to Pennsylvania agency experiences during the accident, the decision was made soon after to develop a staff of nuclear engineers, each giving special day-to-day attention to a specific nuclear power station in the state. Changes in communications capabilities are significant, these being dedicated phone lines between the Commonwealth and each power station, and the reorientation of the Department of Environmental Resources radio network to accommodate direction of field monitoring teams from Harrisburg. Changes that are being or will be implemented in the near future include assessing the emergency response data system for electronic delivery of plant parameter data form facilities during accidents, increased participation in exercises, emergency medical planning, and training, the inclusion of all 67 counties in Pennsylvania in an ingestion EPZ, and the gradual severance of dependence on land-line emergency communication systems

  9. Responsible marketing for sustainable tourism

    2014-01-01

    Full Text Available The biggest challenge associated with the concept of sustainable tourism is its operationalisation and perception as a process to be applied through development plans, projects and ongoing activities of tour operators. The traditional approach to marketing, focused on a limited idea of maximising profit businesses, was not able to respond to a number of social and environmental requirements imposed by the concept of sustainable development. This paper discusses the ways in which marketing could play a more important role in the sustainable development of tourism. This refers to the determination of consumer needs and preferences, the formation of certain products and pricing, product information and advertising to consumers of their benefits in a sustainable manner, as well as adequate distribution channels used by businesses to deliver products to consumers. Environmental and social marketing are now being confirmed as important elements of a much broader marketing perspective. In order to develop tourism with sustainable outcomes, responsible marketing can be crucial. The concept of marketing mix for sustainable tourism was used as a starting point to explore the specific role of responsible marketing in tourism.

    2001-01-01

    Otto Hahn (1879-1968) was awarded the 1944 Nobel Prize for Chemistry for his work on atomic fission: his work in Berlin in the 1930s and 1940s with Lise Meitner and Fritz Strassmann led to the discovery that uranium nuclei bombarded by neutrons undergo spontaneous fission, releasing enormous energies. This work, conveyed to England and the US by scientific refugees from Nazi Germany, led to the instigation of the Manhattan Project and the development of the Atomic Bomb. Reviled by many after the war as one of the people responsible for the carnage at Hiroshima and Nagasaki, Hahn had already begun to reflect on the social responsibility of scientists for their fundamental discoveries and the subsequent applications of the knowledge they create. Already during the war, Hahn had protested Nazi restrictions on Universities and researchers, and after the War, he became actively involved in efforts to restrict the spread of nuclear weapons. In this volume Klaus Hoffmann discusses Hahn's contributions to science and...

  12. Radiation response and chromatin dynamics

    International Nuclear Information System (INIS)

    Ikura, Tsuyoshi

    2009-01-01

    Described is a recent progress in studies of chromatin structural alterations induced by DNA damage by radiation. DNA in eukaryotes exists in the chromatin structure and different mechanisms of response to damage and repair of DNA from those in prokaryotes have been recognized. Chromatin is composed from its unit structure of mono-nucleosome, which is formed from DNA and an octamer of core histones of H2A, H2B, H3 and H4. When DNA is damaged, histone structural alterations are required for repair factors and checkpoint proteins to access the damaged site. At the actual genome damage, chemical modification of histone to work as a code occurs dependently on the damage where chromatin remodeling factors and histone chaperone participate for structural alteration and remodeling. As well, the exchange of histone variants and fluidization of histones are recently reported. Known chemical modification involves phosphorylation, acetylation and ubiquitination of H2AX (a variant of H2A), and acetylation and methylation of H3. Each complex of TIP60, NuA4 and INO80 is known to be included in the regulation of chromatin with damaged/repaired DNA for remodeling, but little is known about recruitment of the factors concerned at the damage site. Regulatory mechanisms in above chromatin dynamics with consideration of quality and timing of radiation should be further elucidated for understanding the precise response to DNA damage. (K.T.)

    2015-01-01

    Full Text Available DNA damage response (DDR involves DNA repair, cell cycle regulation and apoptosis, but autophagy is also suggested to play a role in DDR. Autophagy can be activated in response to DNA-damaging agents, but the exact mechanism underlying this activation is not fully understood, although it is suggested that it involves the inhibition of mammalian target of rapamycin complex 1 (mTORC1. mTORC1 represses autophagy via phosphorylation of the ULK1/2–Atg13–FIP200 complex thus preventing maturation of pre-autophagosomal structures. When DNA damage occurs, it is recognized by some proteins or their complexes, such as poly(ADPribose polymerase 1 (PARP-1, Mre11–Rad50–Nbs1 (MRN complex or FOXO3, which activate repressors of mTORC1. SQSTM1/p62 is one of the proteins whose levels are regulated via autophagic degradation. Inhibition of autophagy by knockout of FIP200 results in upregulation of SQSTM1/p62, enhanced DNA damage and less efficient damage repair. Mitophagy, one form of autophagy involved in the selective degradation of mitochondria, may also play role in DDR. It degrades abnormal mitochondria and can either repress or activate apoptosis, but the exact mechanism remains unknown. There is a need to clarify the role of autophagy in DDR, as this process may possess several important biomedical applications, involving also cancer therapy.

    The most commonly used method in the seismic analysis of structures is the response spectrum method. For seismic re-evaluation of existing facilities elastic response spectrum method cannot be used directly as large deformation above yield may be observed under Safe Shutdown Earthquake (SSE). The plastic deformation, i.e. hysteretic characteristics of various elements of the structure cause dissipation of energy. Hence the values of damping given by the code, which does not account hysteretic energy dissipation cannot be directly used. In this paper, appropriate damping values are evaluated for 5-storey, 10-storey and 15-storey shear beam structures, which deform beyond their yield limit. Linear elastic analysis is performed for the same structures using these damping values and the storey forces are compared with those obtained using inelastic time history analysis. A damping model, which relates ductility of the structure and damping, is developed. Using his damping model, a practical structure is analysed and results are compared with inelastic time history analysis and the comparison is found to be good

    Dicks, B.M.; White, I.C.

    1992-01-01

    The incidence of oil spills from offshore industry operates on the United Kingdom continental shelf is reported for the period 1979 to 1988. The properties of North Sea crude oils which determine their fate and effects when spilled onto the surface of the sea are summarized. Examples of oil impacts on specific North Sea habitats and communities are used to illustrate the effect of oil spills and the economic impact on human activities such as recreation, industry and fishing are considered. Since most oil spills will dissipate through natural processes if they remain at sea long enough, the most appropriate response to a spill from a platform in the middle of the sea is often aerial surveillance to monitor the movement and dissipation of the oil. However, if an active response is required, containment and collection of the oil or chemical dispersion are the two main options. In coastal waters, it will be necessary to focus protection efforts on selected sensitive areas of coastline. Once the oil is ashore there are still occasions when the best course of actions is to do nothing as clean-up operations may do more harm than good. If oil removal is feasible and necessary, the methods which are most effective are usually straightforward and require no sophisticated technology. Contingency planning is an essential preparation for all operations to deal with oil spills. (UK)

    Microfluidic channels manufactured from PDMS are a key component of lab-on-a-chip devices. Experimentally, rectangular microchannels are found to deform into a non-rectangular cross-section due to fluid-structure interactions. Deformation affects the flow profile, which results in a nonlinear relationship between the volumetric flow rate and the pressure drop. We develop a framework, within the lubrication approximation (l >> w >> h), to self-consistently derive flow rate-pressure drop relations. Emphasis is placed on handling different types of elastic response: from pure plate-bending, to half-space deformation, to membrane stretching. The ``simplest'' model (Stokes flow in a 3D rectangular channel capped with a linearly elastic Kirchhoff-Love plate) agrees well with recent experiments. We also simulate the static response of such microfluidic channels under laminar flow conditions using ANSYSWorkbench. Simulations are calibrated using experimental flow rate-pressure drop data from the literature. The simulations provide highly resolved deformation profiles, which are difficult to measure experimentally. By comparing simulations, experiments and our theoretical models, we show good agreement in many flow/deformation regimes, without any fitting parameters.

  17. Comparing bee species responses to chemical mixtures: Common response patterns?

    Directory of Open Access Journals (Sweden)

    Full Text Available Pollinators in agricultural landscapes can be exposed to mixtures of pesticides and environmental pollutants. Existing mixture toxicity modelling approaches, such as the models of concentration addition and independent action and the mechanistic DEBtox framework have been previously shown as valuable tools for understanding and ultimately predicting joint toxicity. Here we apply these mixture models to investigate the potential to interpret the effects of semi-chronic binary mixture exposure for three bee species: Apis mellifera, Bombus terrestris and Osmia bicornis within potentiation and mixture toxicity experiments. In the potentiation studies, the effect of the insecticide dimethoate with added propiconazole fungicide and neonicotinoid insecticide clothianidin with added tau-fluvalinate pyrethroid acaricide showed no difference in toxicity compared to the single chemical alone. Clothianidin toxicity showed a small scale, but temporally conserved increase in exposure conducted in the presence of propiconazole, particularly for B. terrestris and O. bicornis, the latter showing a near three-fold increase in clothianidin toxicity in the presence of propiconazole. In the mixture toxicity studies, the dominant response patterns were of additivity, however, binary mixtures of clothianidin and dimethoate in A. mellifera, B. terrestris and male O. bicornis there was evidence of a predominant antagonistic interaction. Given the ubiquitous nature of exposures to multiple chemicals, there is an urgent need to consider mixture effects in pollinator risk assessments. Our analyses suggest that current models, particularly those that utilise time-series data, such as DEBtox, can be used to identify additivity as the dominant response pattern and also those examples of interactions, even when small-scale, that may need to be taken into account during risk assessment.

  20. Dose-response curves from incomplete data

    International Nuclear Information System (INIS)

    Groer, P.G.

    1978-01-01

    Frequently many different responses occur in populations (animal or human) exposed to ionizing radiation. To obtain a dose-response curve, the exposed population is first divided into sub-groups whose members received the same radiation dose. To estimate the response, the fraction of subjects in each sub-group that showed the particular response of interest is determined. These fractions are plotted against dose to give the dose-response curve. This procedure of plotting the fractions versus the radiation dose is not the correct way to estimate the time distribution for a particular response at the different dose levels. Other observed responses competed for the individuals in the exposed population and therefore prevented manifestation of the complete information on the response-time distribution for one specific response. Such data are called incomplete in the statistical literature. A procedure is described which uses the by now classical Kaplan-Meier estimator, to establish dose-response curves from incomplete data under the assumption that the different observed responses are statistically independent. It is demonstrated that there is insufficient information in the observed survival functions to estimate the time distribution for one particular response if the assumption of independence is dropped. In addition, it is not possible to determine from the data (i.e. type of response and when it occurred) whether or not the different response-time distributions are independent. However, it is possible to give sharp bounds between which the response has to lie. This implies that for incomplete data, only a 'dose-response band' can be established if independence of the competing responses cannot be assumed. Examples are given using actual data to illustrate the estimation procedures

  1. A simplified multisupport response spectrum method

    Science.gov (United States)

    Ye, Jihong; Zhang, Zhiqiang; Liu, Xianming

    2012-03-01

    A simplified multisupport response spectrum method is presented. The structural response is a sum of two components of a structure with a first natural period less than 2 s. The first component is the pseudostatic response caused by the inconsistent motions of the structural supports, and the second is the structural dynamic response to ground motion accelerations. This method is formally consistent with the classical response spectrum method, and the effects of multisupport excitation are considered for any modal response spectrum or modal superposition. If the seismic inputs at each support are the same, the support displacements caused by the pseudostatic response become rigid body displacements. The response spectrum in the case of multisupport excitations then reduces to that for uniform excitations. In other words, this multisupport response spectrum method is a modification and extension of the existing response spectrum method under uniform excitation. Moreover, most of the coherency coefficients in this formulation are simplified by approximating the ground motion excitation as white noise. The results indicate that this simplification can reduce the calculation time while maintaining accuracy. Furthermore, the internal forces obtained by the multisupport response spectrum method are compared with those produced by the traditional response spectrum method in two case studies of existing long-span structures. Because the effects of inconsistent support displacements are not considered in the traditional response spectrum method, the values of internal forces near the supports are underestimated. These regions are important potential failure points and deserve special attention in the seismic design of reticulated structures.

  2. PUBLIC GOVERNANCE AND STRATEGIC RESPONSIVENESS

    2014-06-01

    Full Text Available In the actual context, where globalization is moreover dynamic, the concept of solid state, well defined and territorialised is becoming diffuse while the traditional social connections (labour relations, community solidarity are becoming weaker and more fragile. The economic individualisation, migration and cultural fragmentation hold a devastating impact upon the living environment, namely significant growth of anonymity, distrust and discontent. As effect of those realities, the governments are searching responses to these processes of “social liquefaction”. Taking into consideration the fact that that the governance tools based on authority, hierarchy and bureaucracy are becoming useless due to the lack of effectiveness and legitimacy, we witness the emergence of new modes of public governance, in light to reconfigure solid ground, adequate for interventions. The design of a new type of governance should take into consideration its dual character. One component aims accountable community, as the traditional society has demonstrated that it is not able to generate spontaneously neither trust nor social capital. The second component is focused on identifying those strategies providing that accountability should be taken jointly by the public authorities and the other actors such as companies, third sector organisations and citizens. The accomplishment of such a model means to overcome several challenges. On the one hand, are the members of the community aware of the importance of their commitment? Are they truly motivated to participate in such a structure? On the other hand, how prepared are the political representatives and public authorities to accept cooperation with various categories of actors at community level? The space of strategic responsiveness introduced by the current research provides a possible scenario for responding to the above questions. Additionally, the research attempts to provide an answer to a special question

  4. Light Pollution Responses and Remedies

    CERN Document Server

    Mizon, Bob

    2012-01-01

    Light pollution is a major threat to astronomy across the entire developed world. The night sky that most of us can see bears little relationship to the spectacular vistas that our ancestors have gazed at for tens of thousands of years. It is ironic that as our understanding of the universe has improved, our ability to see it has been dramatically reduced by the skyglow of our civilization. In the second edition of Light Pollution - Responses and Remedies, Bob Mizon delves into the history and practice of lighting and how its misue has not only stolen the stars, but blighted our lives and those of our fellow-creatures on this planet. This book suggests how we can win back the night sky and at the same time save energy and money, improve our health, and even lower crime rate! It also includes a list of targets for urban stargazers, and recommendations for ensuring sane lighting worldwide.

  5. Radiation Response of Rhombohedral Oxides

    Devanathan, R.; Weber, W.J.; Mitchell, J.N.; Sickafus, K.E.; Nastasi, M.

    1997-05-01

    The radiation response of three rhombohedral oxides, namely, sapphire (α-Al 2 O 3 ), ilmenite (FeTiO 3 ), and geikielite (MgTiO 3 ), has been examined by irradiating electron transparent samples with 1 MeV Kr(+) and 1.5 MeV Xe(+)ions. The microstructural changes during irradiation were observed in situ in a high-voltage electron microscope using electron diffraction and microscopy. The irradiation conditions were designed to minimize beam heating and chemical effects due to the implanted ion. Of the three oxides studied, ilmenite is the most susceptible to radiation-induced amorphization while sapphire is the least susceptible. In all three materials, the critical temperature for amorphization was below 300 K indicating good room temperature resistance to amorphization by energetic beams

    Souza, Leonardo Rocha; Soares, Lacir Jorge

    2007-01-01

    This paper studies the electricity load demand behavior during the 2001 rationing period, which was implemented because of the Brazilian energy crisis. The hourly data refers to a utility situated in the southeast of the country. We use the model proposed by Soares and Souza [Soares, L.J. and Souza, L.R. (2006), 'Forecasting electricity demand using generalized long memory', International Journal of Forecasting, 22, 17-28.], making use of generalized long memory to model the seasonal behavior of the load. The rationing period is shown to have imposed a structural break in the series, decreasing the load at about 20%. Even so, the forecast accuracy is decreased only marginally, and the forecasts rapidly readapt to the new situation. The structural break, as well as the forecast errors from this model, also permits verifying the public response to pieces of information released regarding the crisis. (Author)

  7. Archetypes of famine and response.

    Science.gov (United States)

    Howe, Paul

    2010-01-01

    Famines have long been characterised by rapidly shifting dynamics: sudden price spirals, sharp increases in mortality, the media frenzy that often accompanies such spikes, the swift scaling up of aid flows, and a subsequent decline in interest. In arguing that these aspects of famine have been largely ignored in recent years due to attention to the famine process', this paper attempts to make these dynamics more explicit by applying systems thinking. It uses standard archetypes of systems thinking to explain six situations--watch, price spiral, aid magnet, media frenzy, overshoot, and peaks--that are present in many famine contexts. It illustrates their application with examples from crises in Ethiopia, Malawi, Niger, and Sudan. The paper contends that the systems approach offers a tool for analysing the larger patterns in famines and for pinpointing the most appropriate responses to them, based on an awareness of the dynamics of the crises.

    The paper referenced some of the functions and responsibilities that the owners, the engineer-constructors and the vendors must share in order to achieve project related objectives. Throughout the paper, it is recognized that the owner is taking the burden of risk. Further, for a particular project, he is being asked, in many areas, to avoid the temptation to advance the state of the art with perhaps its elusive increased efficiencies. Research and development are essential and the industry needs the cooperation of all to improve the end product.

    1986-01-01

    While the study of Kinematic Interaction effects calls, in general, for advanced analytical and numerical techniques, an excellent approximation was proposed recently by Iguchi. This approximation was used by the authors to analyze embedded foundations subjected to spatially random SH-wave fields, i.e., motions that exhibit some degree of incoherence. The wave fields considered ranged from perfectly coherent motions (resulting from seismic waves arriving from a single direction) to chaotic motions resulting from waves arriving simultaneously from all directions. Additional parameters considered were the shape of the foundation (cylindrical, rectangular) and the degree of embedment. It was found that kinematic interaction usually reduces the severity of the motions transmitted to the structure, and that incoherent motions do not exhibit the frequency selectivity (i.e., narrow valleys in the foundation response spectra) that coherent motions do

    Leprosy is an infectious disease that may present different clinical forms depending on host immune response to Mycobacterium leprae. Several studies have clarified the role of various T cell populations in leprosy; however, recent evidences suggest that local innate immune mechanisms are key determinants in driving the disease to its different clinical manifestations. Leprosy is an ideal model to study the immunoregulatory role of innate immune molecules and its interaction with nervous system, which can affect homeostasis and contribute to the development of inflammatory episodes during the course of the disease. Macrophages, dendritic cells, neutrophils, and keratinocytes are the major cell populations studied and the comprehension of the complex networking created by cytokine release, lipid and iron metabolism, as well as antimicrobial effector pathways might provide data that will help in the development of new strategies for leprosy management.

    Etzioni, Amitai

    2011-01-01

    A communitarian approach to bioethics adds a core value to a field that is often more concerned with considerations of individual autonomy. Some interpretations of liberalism put the needs of the patient over those of the community; authoritarian communitarianism privileges the needs of society over those of the patient. Responsive communitarianism's main starting point is that we face two conflicting core values, autonomy and the common good, and that neither should be a priori privileged and that we have principles and procedure that can be used to work out this conflict but not to eliminate it. Additionally, it favours changing behaviour mainly through the creation of norms and by drawing on informal social control rather than by coercion.

The use of a new, high-resolution ultrasound machine to measure arterial size in 25 migraine patients with unilateral head pain showed...... that the lumen was wider on the painful than on the non-painful side during a migraine attack. The diameters of both radial arteries and the temporal artery on the non-painful side were smaller during than between attacks.

  14. Staphylococcal response to oxidative stress

    2012-03-01

    Full Text Available Staphylococci are a versatile genus of bacteria that are capable of causing acute and chronic infections in diverse host species. The success of staphylococci as pathogens is due in part to their ability to mitigate endogenous and exogenous oxidative and nitrosative stress. Endogenous oxidative stress is a consequence of life in an aerobic environment; whereas, exogenous oxidative and nitrosative stress are often due to the bacteria’s interaction with host immune systems. To overcome the deleterious effects of oxidative and nitrosative stress, staphylococci have evolved protection, detoxification, and repair mechanisms that are controlled by a network of regulators. In this review, we summarize the cellular targets of oxidative stress, the mechanisms by which staphylococci sense oxidative stress and damage, oxidative stress protection and repair mechanisms, and regulation of the oxidative stress response. When possible, special attention is given to how the oxidative stress defense mechanisms help staphylococci control oxidative stress in the host.

  17. [Moral responsibility of hospital management].

    Science.gov (United States)

    Schmidt-Wilcke, Heinrich Alyosius

    2009-03-15

    The self-concept of hospitals today includes the role of service providers, and so they act accordingly. This attitude is chiefly held by hospital administrators. It means that at management level there is a shift of values toward business ethics. However, hospital management is responsible not only for the business aspects of the hospital but also for the provision of adequate medical care to patients. Therefore, hospitals as service providers must be governed by the principles of medical as well as of business ethics. These principles, although from different areas, can be made to largely coincide, but can also lead to divergent positions within a hospital. The result is what within the scope of medical ethics, too, is experienced as a conflict of principles, e.g., the principle of beneficence versus the principle of autonomy. A reconciliation of such divergent moral positions can often be effected by analyzing the actual conflict situation and thus reaching consensus. The conflict between the principles of medical ethics and business ethics takes place chiefly within the sphere of activity of those providing medical and nursing care. As a consequence, a necessary business decision taken by the management to improve the productivity of medical and nursing activities can lead to serious deficits on the staff side. In terms of business ethics, this is a lack of beneficence toward individual staff members that are perhaps overtaxed, and at the same time, in terms of medical ethics, a potential lack of beneficence toward hospital patients is implicitly accepted. In general, management has the responsibility for bringing about, in the day-to-day operation of a hospital, a plausible reconciliation of the ethical principles of two spheres of activity that are only apparently independent of each other.

  18. Volcanic hazards and public response

    Science.gov (United States)

    Peterson, Donald W.

    1988-05-01

    Although scientific understanding of volcanoes is advancing, eruptions continue to take a substantial toll of life and property. Some of these losses could be reduced by better advance preparation, more effective flow of information between scientists and public officials, and better understanding of volcanic behavior by all segments of the public. The greatest losses generally occur at volcanoes that erupt infrequently where people are not accustomed to dealing with them. Scientists sometimes tend to feel that the blame for poor decisions in emergency management lies chiefly with officials or journalists because of their failure to understand the threat. However, the underlying problem embraces a set of more complex issues comprising three pervasive factors. The first factor is the volcano: signals given by restless volcanoes are often ambiguous and difficult to interpret, especially at long-quiescent volcanoes. The second factor is people: people confront hazardous volcanoes in widely divergent ways, and many have difficulty in dealing with the uncertainties inherent in volcanic unrest. The third factor is the scientists: volcanologists correctly place their highest priority on monitoring and hazard assessment, but they sometimes fail to explain clearly their conclusions to responsible officials and the public, which may lead to inadequate public response. Of all groups in society, volcanologists have the clearest understanding of the hazards and vagaries of volcanic activity; they thereby assume an ethical obligation to convey effectively their knowledge to benefit all of society. If society resists, their obligation nevertheless remains. They must use the same ingenuity and creativity in dealing with information for the public that they use in solving scientific problems. When this falls short, even excellent scientific results may be nullified.

  16. Onus of responsibility: the changing responsible corporate officer doctrine.

    Science.gov (United States)

    Bragg, Jennifer; Bentivoglio, John; Collins, Andrew

    2010-01-01

    The responsible corporate officer ("RCO") doctrine permits convictions of corporate officers for violations of the Federal Food, Drug, and Cosmetic Act ("FDCA"), even in instances in which the corporate officer was not personally involved and lacked knowledge of the wrongdoing. Prosecutors have seldom prosecuted RCO FDCA cases since the doctrine was first described in 1943, but recent indications point to an imminent revival. Cases and statements from government officials indicate that this second wave of the RCO doctrine may sweep more broadly than did the first. For example, prosecutors appear ready to employ the RCO doctrine in strict liability cases, even though most past RCO FDCA cases involved knowledge on the part of the corporate officer. Moreover, the current environment promises stiffer penalties, less centralized case selection, and fewer jury trials than did the era in which the RCO doctrine was established.
