Demands, Resources and the Three Dimensions of Flow at Work. A Study among Professional Nurses

Within the healthcare context is very important to foster the dynamics leading to positive experiences at work, in order to promote work motivation and well-being. This study investigated the influence of some personal and job resources and of some job demands on the three dimensions (absorption, work enjoyment, intrinsic work motivation) of flow at work, on the basis of Job Demands-Resources Model. Flow at work is an inner experience arising during an activity in which people are immersed, feel motivated and enjoy it. Studies suggest that resources are the main antecedents of the flow experience. Respondents to the questionnaire were 197 nurses. Multiple regressions were performed to detect the resources and the demands that influence the three dimensions of flow at work. As expected, resources positively influenced the dimensions of flow at work, particularly work enjoyment. Job demands positively influenced absorption and negatively influenced the other two dimensions of flow at work. Human resources managers should promote flow at work supporting the availability of resources and monitoring the job demands.
Coherence of Hemispheric Function in Developmental Dyslexia

Left parieto-occipital EEG leads record a frequency spectrum in dyslexics that is consistently different from the spectrum obtained from normals. It is suggested that these effects represent significant differences in the functional organization of these areas. EEG coherence values indicate that normals have significantly greater sharing between hemispheres at symmetrical locations. Dyslexics demonstrate significantly greater sharing within hemisphere than do normals. The data supports developmental dyslexia being a functional hemispheric disconnection syndrome.
Characterization of Temporal and Cell-Specific Changes in Transcripts for Prostaglandin E2 Receptors in Pseudopregnant Rat Endometrium1

Abstract In the rodent uterus, prostaglandin E2 (PGE2) is believed to have a major role in implantation and decidualization. The present study investigated the temporal and hormonal control of mRNA expression for the four E-prostanoid (EP1–4) receptors in the rat endometrium. For Northern blot analysis and in situ hybridization, samples were obtained from rats on Days 1–10 of pseudopregnancy or from rats differentially sensitized for the decidual cell reaction with estradiol. No EP1 mRNA signal was detected. Endometrial EP2 and EP3 mRNA levels increased to a maximum on Day 5, and the mRNAs were localized to the luminal epithelium at the antimesometrial pole, and in the endometrial stroma and glandular epithelium, respectively. Endometrial EP4 mRNA levels were unchanged on Days 1–5, but the mRNA was concentrated in the antimesometrial endometrial stroma on Day 5. Cell-specific expression of EP2, EP3, and EP4 on Day 5 was dependent upon a dose of estradiol given on Day 4 that induced differential uterine sensitization on Day 5. After the application of a deciduogenic stimulus on Day 5, mRNA levels for these receptors decreased significantly, while in nonstimulated horns they remained elevated. Overall, these results support a role for PGE2 in the onset of receptivity and initiation of decidualization in the rat.
Neuronal substrate of classical conditioning in the hippocampus

Neuronal activity in dorsal hippocampus was recorded in rabbits-during classical conditioning of nictitating membrane response, with tone as conditioned stimulus and corneal air puff as unconditioned stimulus. Unit activity in hippocampus rapidly forms a temporal neuronal "model" of the behavioral response early in training. This hippocampal response does not develop in control animals given unpaired stimuli.
Intra-Annual Variability of Silver Carp Populations in the Des Moines River, USA

AbstractSince their introduction in the 1970s, Silver Carp Hypophthalmichthys molitrix have spread throughout the Mississippi River basin. Management of any species relies on an accurate understanding of population characteristics and dynamics. However, Silver Carp seasonal sampling variation is unknown. Sampling during periods of peak catch rates would facilitate Silver Carp assessment and management, improving monitoring and removal techniques. The objective of this study was to evaluate adult Silver Carp seasonal sampling variation with boat electroshocking and trammel nets. Silver Carp were collected monthly (April–October) during 2014 and 2015 from four locations in the Des Moines River, Iowa. Trammel nets rarely captured Silver Carp (mean ± SE = 4.9 ± 1.6 fish/net; 60% of fish were captured in 6.3% of net sets) and therefore were not included in analyses. Electroshocking catch rates (CPUEs) exhibited a bimodal distribution, with peak CPUEs generally occurring in May, June, and September and lower ca.
Arranging and ordering in autism spectrum disorder: Characteristics, severity, and environmental correlates

Abstract Background There is a need for a more accurate characterisation of higher level restricted and repetitive behaviour (RRB) in autism spectrum disorder (ASD), including why it might be considered problematic and events associated with its occurrence. Method We selected one form of higher level RRB—arranging and ordering—that was rated as severe for a large percentage of the population sampled. We interviewed 20 students’ teachers and conducted naturalistic observations for 15 of those students. Results The characteristics of arranging and ordering varied across, and sometimes within, individuals. Problems associated with compulsive-like1 behaviour also varied, with several unanticipated reported problems. With the exception of attention, social consequences were relatively infrequent. Conclusions These data highlight the need for research on the assessment and treatment of arranging and ordering and clinical attention to compulsive-like behaviour in ASD. Interviews and naturalistic observations are useful for structuring additional observations and analyses.
CIRCADIAN OXYGEN CONSUMPTION PATTERNS IN CONTINENTAL SLOPE NEPHROPS NORVEGICUS (DECAPODA: NEPHROPIDAE) IN THE WESTERN MEDITERRANEAN

Abstract The oxygen consumption of Nephrops norvegicus animals collected from the upper continental slope (400 m depth) in the northwestern Mediterranean was monitored under constant conditions of darkness and temperature. Two experiments were performed starting at the beginning of the expected day and at the beginning of the expected night phases, respectively. Mean oxygen consumption values recorded during the expected night were significantly higher than those recorded during the expected day. The slopes of the time series of oxygen consumption data of the two experiments were recalculated in consecutive 1-h intervals, being then averaged for corresponding 1-h time intervals. The plotting over a 24-h cycle of these mean hourly-values revealed a global nocturnal increase in the oxygen consumption in the laboratory. This result is discussed and compared with previously reported catch patterns accounting for emergence from burrows in the field, and locomotor and cardiac activity rhythms recorded in constant conditions in the laboratory in animals from the same depth.
O Sole Mio An Experimental Analysis of Weather and Risk Attitudes

This paper provides direct experimental evidence of the effect of sunshine and good weather on individual risk taking. By employing the multiple price list method of Holt and Laury (2002), we show that, after controlling for other vari- ables such as gender, religion and income, sunshine and good weather promote risk taking. This effect is present whether relying on objective measures of mete- orological conditions or subjective weather assessments. We find that bad weather increases our risk aversion estimates by an average of 40%.
“Abnormal” illness behaviour in chronic fatigue syndrome and multiple sclerosis

Abstract Objective: To investigate the presence of abnormal illness behaviour in patients with a diagnosis of chronic fatigue syndrome. Design: A cross sectional descriptive study using the illness behaviour questionnaire to compare illness behaviour scores and illness behaviour profiles of patients with chronic fatigue syndrome and patients with multiple sclerosis. Setting: A multidisciplinary fatigue clinic and a teaching hospital neurology outpatient clinic. Subjects: 98 patients satisfying the Oxford criteria for chronic fatigue syndrome and 78 patients with a diagnosis of multiple sclerosis. Main outcome measure: Responses to the 62 item illness behaviour questionnaire. Results: 90 (92%) patients in the chronic fatigue syndrome group and 70 (90%) in the multiple sclerosis group completed the illness behaviour questionnaire. Both groups had significantly high scores on the general hypochondriasis and disease conviction subscales and significantly low scores on the psychological versus somatic concern subscale, as measured in relation to normative data. There were, however, no significant differences in the subscale scores between the two groups and the two groups had identical illness behaviour profiles. Conclusion: Scores on the illness behaviour questionnaire cannot be taken as evidence that chronic fatigue syndrome is a variety of abnormal illness behaviour, because the same profile occurs in multiple sclerosis. Neither can they be taken as evidence that chronic fatigue and multiple sclerosis share an aetiology. More needs to be known about the origins of illness beliefs in chronic fatigue syndrome, especially as they are important in determining outcome.
Post-Caesarean ovulation in the rat.

Delivery by Caesarean Section (CS) of pregnant rats at 09.00 hours on the 23rd day of gestation reduced the range of times of ovulation after parturition by 18 hr. Ovulation had not occurred by 15 hr after CS but was completed by 18 hr, an interval which is similar to that of ovulation for females of this colony littering at 09.00 hours. Operation on Day 21 or 22 post coitum did not change the day of ovulation (Day 24) but CS on Days 19 or 20 advanced ovulation to Days 22 or 23, respectively. Prevention of normal delivery by ligation of the uterine horns on Day 22 resulted in no females ovulating on Day 24, and few females ovulating on Days 25 and 26. In such females, CS did not increase the number of rats ovulating.
Cyclooxygenase-1 haplotype C50T/A-842G does not affect platelet response to aspirin

Summary COX-1 polymorphism C50T, in complete linkage disequilibrium with the other polymorphism A-842G, has been depicted as a determinant of pharmacological response to aspirin treatment. Whether these polymorphisms exert an effect on response to aspirin both in vitro and ex vivo is still controversial. We geno-typed a population of 148 healthy individuals for the C50T/A-842G haplotype. Thirty of them underwent low-dose aspirin (100 mg daily) treatment for four weeks and were followed up for seven days after withdrawal. In this subgroup, we evaluated the thromboxane-dependence of biochemical and functional indexes used to monitor the antiplatelet effect of low-dose aspirin. Among the 148 subjects studied, 10 were heterozygous for the C50T/A-842G haplotype (6.7%) and only one was homozygous for the 50T/-842G haplotype (0.67%). In the group on low-dose aspirin, serum thromboxane (TX) B2 as well as urinary 11-dehydro-TXB2 and arachidonic acid (AA)-induced aggregation were similarly suppressed in carriers and non-carriers of the 50T/-842G haplotype, with an increase until basal levels of all the parameters within seven days after withdrawal. We found no relationship between the 50T/-842G haplotype and the so-called phenomenon of aspirin resistance. Platelet cyclooxygenase activity, as reflected by serum TXB2, was uniformly and persistently suppressed by low-dose aspirin in both carriers and non carriers of these polymorphisms.
Mitochondrial Adenosine Triphosphate–regulated Potassium Channel Opening Acts as a Trigger for Isoflurane-induced Preconditioning by Generating Reactive Oxygen Species

Background Whether the opening of mitochondrial adenosine triphosphate–regulated potassium (KATP) channels is a trigger or an end effector of anesthetic-induced preconditioning is unknown. We tested the hypothesis that the opening of mitochondrial KATP channels triggers isoflurane-induced preconditioning by generating reactive oxygen species (ROS) in vivo. Methods Pentobarbital-anesthetized rabbits were subjected to a 30-min coronary artery occlusion followed by 3 h reperfusion. Rabbits were randomly assigned to receive a vehicle (0.9% saline) or the selective mitochondrial KATP channel blocker 5-hydroxydecanoate (5-HD) alone 10 min before or immediately after a 30-min exposure to 1.0 minimum alveolar concentration (MAC) isoflurane. In another series of experiments, the fluorescent probe dihydroethidium was used to assess superoxide anion production during administration of 5-HD or the ROS scavengers N-acetylcysteine or N-2-mercaptopropionyl glycine (2-MPG) in the presence or absence of 1.0 MAC isoflurane. Myocardial infarct size and superoxide anion production were measured using triphenyltetrazolium staining and confocal fluorescence microscopy, respectively. Results Isoflurane (P < 0.05) decreased infarct size to 19 ± 3% (mean ± SEM) of the left ventricular area at risk as compared to the control (38 ± 4%). 5-HD administered before but not after isoflurane abolished this beneficial effect (37 ± 4% as compared to 24 ± 3%). 5-HD alone had no effect on infarct size (42 ± 3%). Isoflurane increased fluorescence intensity. Pretreatment with N-acetylcysteine, 2-MPG, or 5-HD before isoflurane abolished increases in fluorescence, but administration of 5-HD after isoflurane only partially attenuated increases in fluorescence produced by the volatile anesthetic agent. Conclusions The results indicate that mitochondrial KATP channel opening acts as a trigger for isoflurane-induced preconditioning by generating ROS in vivo.
Expression of vitamin D receptor as a potential prognostic factor and therapeutic target in pancreatic cancer

Vitamin D insufficiency and deficiency are common among patients with pancreatic carcinoma, but epidemiological studies have shown inconsistent results for vitamin D intake/circulation level and pancreatic cancer risk. The study aims were to investigate the effects of vitamin D on patient survival, and the proliferation or survival of pancreatic cancer cell lines.
The effect of recasting on corrosion of DUCINOX prosthetic alloy

The effect of recasting, up to two times, Ni-Cr (DUCINOX) prosthetic alloy on its corrosion properties was carried out. The corrosion measurements were done in deoxygenated Fusayama Meyer artificial saliva solution at temperature of 37°C. In the study following electrochemical methods were used: measurement of free corrosion potential Ecor in open circuit, measurement of polarization resistance according to Stern-Geary's method and measurement of potentiodynamic characteristic in wide range of anodic polarization. In general, it can be stated that casting number weakly influence on corrosion properties of investigated alloy. At free corrosion potential there is no monotonic dependence of corrosion parameters versus casting number. However, at extreme anodic potentials monotonic changes of corrosion parameters with increasing casting number is observed. Obtained results and drawn conclusions are partially compatible with literature data.
The long-term course of depressive disorders in the Lundby Study

Background. The Lundby Study is a longitudinal cohort study on a geographically defined population consisting of 3563 subjects. Information about episodes of different disorders was collected during field investigations in 1947, 1957, 1972 and in 1997. Interviews were carried out about current health and past episodes since the last investigation; for all subjects information was also collected from registers, case-notes and key informants. This paper describes the course and outcome of 344 subjects who had their first onset of depression during the follow-up. Method. In this study individuals who had experienced their first episode of depression were followed up. Their course was studied with regard to recurrence of depression related to duration of follow-up, transition to other psychiatric disorders including alcohol disorders, as well as incidence and risk factors of suicide. Results. Median age at first onset of depression was around 35 years for individuals followed up for 30–49 years. The recurrence rate was about 40% and varied from 17% to 76% depending on length of follow-up. Transition to diagnoses other than depression was registered in 21% of the total sample, alcohol disorders in 7% and bipolar disorder in 2%. Five per cent committed suicide; male gender and severity of depression were significant risk factors. Conclusion. The low rates of recurrence and suicide suggest a better prognosis for community samples than for in- and out-patient samples.
Macroscopic study of the social networks formed in web-based discussion forums

It is proposed and outlined in this paper on how to investigate the macroscopic features of those large-size social networks formed in web-based discussion forums. Some preliminary results on the pattern of the distribution of replies for individual topics, views for individual topics and co-discussants of individual participants will be presented. The present results will be compared with those found in other areas of large-size social networks and the significances and future work on those macroscopic properties of social networks for better understanding of computer-supported collaborative learning will be discussed.
Development and Evaluation of an Impactor for a PM2.5 Speciation Sampler

ABSTRACT A conventional impactor for a particle speciation sampler was developed and validated through laboratory and field tests. The speciation sampler consists of the following components: a PM2.5 conventional impactor that removes particles larger than 2.5 μm, an all-glass, coated honeycomb diffusion denuder, and a 47-mm filter pack. The speciation sampler can operate at two different sampling rates: 10 and 16.7 L/min. An experimental characterization of the impactor’s performance was conducted. The impactor’s collection efficiency was examined as a function of critical design parameters such as Reynolds number, the distance from the nozzle exit to the impac-tion plate, and the impaction substrate coating method. The bounce of particles larger than the cut point was successfully minimized by using a greased surface as the im-paction substrate. Additionally, a series of field intercomparison experiments were conducted at both 10 and 16.7 L/min airflow. PM2.5 mass and SO4 2- concentrations were measured and compared with the Federal Reference Method (FRM) and found to be in good agreement. Results of the laboratory chamber tests also indicated that the impactor’s performance was in good agreement with the FRM.
Effects of spaceflight on rat peripheral blood leukocytes and bone marrow progenitor cells

The white blood cell (WBC) elements and the bone marrow myeloid progenitor cell populations were analyzed to ascertain adaptation to microgravity and subsequent readaptation to 1 G in rats flown on the 14‐day Spacelab Life Sciences‐2 (SLS‐2) mission. Bone marrow cells were harvested from one group of rats killed inflight (FD13) and blood was drawn from three other groups at various times. The WBC level was normal on FD14 with the exception of neutrophilia. On FD13, numbers of colony‐forming units‐granulocyte (CFU‐G), CFU‐GM, and CFU‐M from flight animals were decreased compared with ground controls when incubated with recombinant rat interleukin‐3 (rrIL‐3) alone or in combination with recombinant human erythropoietin (rhEpo). On recovery (R + 0), flight rats had decreased numbers of total leukocytes and absolute numbers of lymphocytes and monocytes with elevated neutrophils compared with control rats. They had lower numbers of CD4, CD8, CD2, CD3, and B cells in the peripheral blood but no differences in spleen lymphocytes.
Risk Perception and Communication Regarding Pesticide Use in Rural Work: A Case Study in Rio de Janeiro State, Brazil

Abstract In an agricultural region of Rio de Janeiro State, Brazil, rapid assessment procedures were used for riskperception studies based on methodologic triangulation that included semi-structured interviews, participatory observations, and focus groups. Data were qualitatively categorized. Women's risk perception was prioritized, as they did not recognize some risks they were exposed to during work activities. To reach women likely to be exposed to pesticides, a photographic soap opera (fotonovela) was constructed in collaboration with rural workers, using community-based participatory research methods. Contents of the riskcommunication strategies included the harmful effects of pesticides. Results showed that the inclusion of risk-perception studies in the development of educative and risk-communication campaigns is very important, bridging research to action.
Emetic reflex arc revealed by expression of the immediate-early gene c- fos in the cat

The organization of the central neuronal circuitry that produces vomiting was explored by mapping the distribution of c-fos protein (Fos)-like immunoreactivity (FLI) as a monitor of functional activity. The brainstem and spinal cord were examined in cats administered multiple emetic drugs (cisplatin, lobeline, protoveratrine, naloxone, apomorphine) or control saline injections. Some animals were decerebrated, paralyzed, and artificially ventilated to avoid possible Fos expression induced by sensory feedback or fluid depletion during vomiting. Fictive vomiting was identified in these animals by a characteristic pattern of respiratory muscle nerve (phrenic and abdominal) coactivation. Tissues were immunoprocessed using an antibody raised against amino acids 1–131 of Fos and the avidin-biotin peroxidase complex method. Enhanced nuclear FLI was observed in experimental animals along portions of the sensorimotor emetic reflex arc, including the nodose ganglia, area postrema, nuclei of the solitary tract (especially medial and subpostrema subnuclei), intermediate reticular zone of the lateral tegmental field, nucleus retroambiguus, C2 inspiratory propriospinal cell region, and dorsal vagal and phrenic motor nuclei. Enhanced FLI was also detected in the raphe magnus, subretrofacial nucleus, and spinal dorsal horn. Regions showing no recognizable differences in FLI between experimental and control animals included the vestibular, cochlear, spinal trigeminal, subtrigeminal, and lateral reticular nuclei. Only minor differences were observed in the distributions of FLI between intact and decerebrate animals. No unique, well-defined group of labeled neurons that might function as a “vomiting center” could be identified. Instead, the pattern of c-fos expression suggests that neurons involved in coordinating the emetic response may radiate from the area postrema and nucleus of the solitary tract to an arc in the lateral tegmental field implicated in somato-autonomic integration.
