This study examined the relationships between obsessive-compulsive symptoms (OCs) and encoding style in a subclinical sample, by using a questionnaire that evaluates the extent to which preexisting schemata (versus cues from the outside world) affect encoding processes (Lewicki, 2005). Research on encoding style has revealed on one hand the existence of individual differences in the tendency to impose interpretive schemata in the process of encoding, and on the other hand the fact that an extremely internal mode of encoding has been found to be related to an increased propensity to self-perpetuate preexisting schemata. Furthermore, internal encoding may contribute to the development of psychopathological symptoms, through the self-perpetuation of dysfunctional schemata. The results confirmed that OCs are connected with an internal encoding style; specific relationships between obsessive-compulsive disorder (OCD) dimensions and internal encoding style were also found. These results are discussed in terms of the role of encoding style in the perpetuation of OCs, and its relationship to the dysfunctional beliefs characterising OCD. [less ▲]

The relationship between the quantity of silver-stained interphasic nucleolar organizer regions (NORs) and nuclear synthetic activity, caryotype, and growth rate was studied in two established neuroblastoma cell lines (CHP 212 and HTB 10). Statistical analysis of silver-stained NORs revealed four times as many in CHP 212 cells compared with HTB 10 cells. No difference was observed in the ribosomal RNA synthesis between the two cell lines. The caryotype index was 1.2 for CHP 212 and 1.0 for HTB 10 cells. The number of chromosomes carrying NORs and the quantity of ribosomal genes was found to be the same for the two cell lines. Doubling time of CHP 212 cells was 20 hours compared with 54 hours for HTB 10 cells. In CHP 212 cells bindering of cell duplication by serum deprivation induced a progressive lowering (calculated at 48, 72, and 96 hours) of the quantity of silver-stained interphasic NORs. Recovery of duplication by new serum addition induced, after 24 hours, an increase of the quantity of silver-stained interphasic NORs up to control levels. In the light of available data, these results indicate that the quantity of interphasic NORs is strictly correlated only to the growth rate of the cell. [less ▲]

Selection for increased mastitis resistance is hampered by lack of available data. Currently, somatic cell count or score are proven indicators. However, it should be a priority to increase the number of available indicator traits for mastitis resistance. The aim of this research was to study the relationships among potential indicator traits as lactoferrin content, concentrations of major minerals in milk (calcium, Ca; sodium, Na; phosphore, P), and somatic cell count. First, 3 calibration equations Breeding and Genetics: Breeding for Milk Quality and Test-Day Model Applications J. Anim. Sci. Vol. 86, E-Suppl. 2/J. Dairy Sci. Vol. 91, E-Suppl. 1 543 were developed using partial least squares regressions to predict the contents of Ca, Na, and P in milk by mid-infrared spectrometry. A total of 1,609 milk samples were collected between March 2005 and May 2006 for 475 cows from 6 dairy breeds. Based on their spectral variability, 100 samples were selected using a principal components approach. The contents of these minerals were estimated by emission spectrometry (ICP-AES). The ratio of standard deviation to standard error of cross validation obtained for the equations predicted the contents of Ca, Na, and P were superior to 2 suggesting the use of these equations in this research. Second, the relationship between lactoferrin, minerals and somatic cells was studied using a random regressions multi-trait animal test-day model. A total of 57,973 milk samples were collected from 94 herds between April 2005 and January 2008 during milk recording in the Walloon part of Belgium. [less ▲]

The aim of the study was to determine if cattle breeds differing in their carcass characteristics also differ in the profiles of their leptin and metabolic hormones. Three breeds, Belgian Blue (BB) (n=12), Limousin (L) (n=12) and Aberdeen Angus (AA) (n=12) with varying ability to deposit fat and protein were compared. Blood, muscle and subcutaneous (SC) adipose tissue were sampled. Animal performance, carcass and meat characteristics were determined as well as plasma leptin concentration, leptin gene expression in SC adipose tissue, leptin-receptor gene expression in SC adipose tissue and plasma concentration of insulin, tri-iodothyronin (T3), thyroxin (T4) and cortisol. The BB bulls showed the lowest values of leptin gene expression (P<0.05). Values of plasma leptin concentration and of leptin-receptor gene expression tended to be lower in BB than in the other breeds. For a similar amount of adipose tissue (after normalisation), BB bulls showed a higher ratio of plasma leptin (P<0.05), whereas normalised leptin gene and leptin-receptor gene expressions did not significantly differ between breeds. Belgian Blue bulls also differed in their metabolic hormone profile, tending to show lower values of insulin, T3 and T4 than the two other breeds. Cortisol levels were significantly lower (P<0.05) in BB than in L and AA animals. [less ▲]

Exercise-induced oxidative stress is investigated as a potential performance-limiting factor in human sports medicine. Therefore, the present study aimed to assess whether physiological variables that change with exercise intensity were correlated with blood oxidant markers in healthy and heaves-affected horses. Seven healthy horses, 8 heaves-affected in remission and 7 heaves-affected in crisis performed a standardised exercise test (SET) of stepwise increasing intensity. Variables monitored during exercise were heart rate (HR), venous plasma lactate (LA), packed cell volume (PCV) and arterial oxygen tension (PaO2). Oxidant markers (uric acid [UA], 8-iso-PGF2alpha and reduced [GSH] and oxidised glutathione [GSSG]) were analysed in venous peripheral blood sampled at rest (R), at peak-exercise intensity (Emax), 15 (E15) and 60 (E60) min after SET. There was a significant effect of heaves on oxidant markers and, therefore, correlation analyses between physiological variables and oxidant markers were performed separately per horse group. In healthy horses, UA analysed at Emax was positively correlated with LA. Furthermore, GSH analysed at Emax and E15 was positively correlated with PaO2. In healthy and heaves-affected horses in remission, GSH and GSSG determined at Emax were negatively correlated with HR. There was no significant correlation between 8-iso-PGF2alpha and physiological variables. In conclusion, a correlation between the physiological response to exercise and some oxidant markers exists in healthy horses. However, in heaves-affected horses the blood oxidant status is probably more dependant on airway disease than on exercise. Future studies should be undertaken to assess whether antioxidant supplementation might positively influence the oxidant-antiodidant balance in exercising horses. [less ▲]

The relationship between maternal caprine pregnancy-associated glycoprotein (cPAG) concentrations and fetal number was investigated in 21 nulliparous and 17 multiparous goats. Using a homologous radioimmunoassay (hm-RIA) cPAG was detected in plasma of pregnant goats from the 21st day of pregnancy. Statistical differences between goats bearing single and multiple fetuses were observed after 63 days to the end of pregnancy, except on day 133. After 126 days (3rd week pre-partum) cPAG levels began to decrease slowly in both the groups. The hm-RIA was an efficient method to describe the relationship between maternal PAO concentrations and number of fetuses in goats. (C) 2001 Published by Elsevier Science B.V. [less ▲]

Objectives: The aim of this study was to evaluate the influence of operator skill on microleakage in class V composite restorations. Materials and Methods : A total of 16 dentists and 25 dental students were enrolled, and 123 extracted teeth were allocated according to the adhesive being tested: Scotchbond Multipurpose, Adper Scotchbond 1 XT, and AdheSE. Each operator was asked to restore one tooth from each experimental group: two class V cavities were cut on each tooth and each adhesive was used on the same tooth before and after instructions for its use. After filling cavities with composite (Z100), the teeth were thermocycled. Results : For all of the tested adhesives, the mean microleakage score was lower for the dentists than for the students. The mean scores for the three tested adhesives were statistically similar before and after instructions for use. Conclusion. Our results indicate that the skill of the operator has a significant influence on microleakage. [less ▲]

The role of transvaginal pulsed colour Doppler ultrasound in the assessment of ovarian vascularity was studied in 196 in-vitro fertilization (IVF) cycles. The changes in ovarian blood flow after gonadotrophin-releasing hormone agonist (GnRHa) down-regulation and human menopausal gonadotrophin (HMG) stimulation were determined. The data obtained showed that the ovarian blood flow was significantly improved by oestradiol secretion (P = 0.05) and human chorionic gonadotrophin (HCG) administration (P = 0.003). Folliculogenesis was affected by blood flow supply. The resistance index (RI) value was significantly different (P = 0.05) according to the duration of ovarian stimulation. Patients with a mean RI value >0.56 had a longer stimulation with a significantly lower mean number of oocytes retrieved (P = 0.01) despite the administration of a standard dose of HMG. The RI value is a good indicator of modifications in ovarian vascularization during stimulation. Doppler blood flow measurement could be used to determine the optimal timing for the beginning of HMG administration in patients undergoing ovarian stimulation after down-regulation for IVF treatment.

Kinetic parameters of parathion and paraoxon uptake were determined in isolated and perfused rabbit and guinea pig lungs. They were related to organophosphate-induced lung cholinesterase inhibition. A single pass procedure was used to perfuse the lungs with an artificial medium perfusate containing paraoxon or parathion. The paraoxon and parathion concentrations were determined in the effluents collected at chosen intervals over an 18-min period beginning at the start of perfusion. Three inflowing concentrations (1 nmol/ml, 10 nmol/ml, and 20 nmol/ml) were tested in guinea pig lungs and one (10 nmol/ml) in rabbit lungs. Cholinesterase activity was determined at time 0 and at the end of the experiment. The lungs abundantly extracted paraoxon and parathion over the perfusion period. The extraction ratio was consistently greater in guinea pig than in rabbit lungs. The uptake velocity varied biexponentially in time, suggesting the existence of two compartments. Initial uptake velocities (A, B) and slopes (alpha and beta) were calculated for both compartments. In guinea pigs, A, B and A + B increased proportionally to the supply rate of paraoxon and parathion while a and b remained constant. No significant difference was observed between parathion and paraoxon uptake kinetics. Parameter B was the only one to differ significantly between the two species (rabbits: 8.19 +/- 1.53 for parathion and 6.85 +/- 1.26 for paraoxon; guinea pigs: 12.75 +/- 0.88 for parathion and 15.02 +/- 3.84 for paraoxon). In the lungs of both species, there was a linear relation between y, the percentage of cholinesterase inhibition induced by either organophosphate, and X, the total amount of drug taken up by the lung tissue (in nmol/g/18 min). The following equations were obtained: y = 0.128 x + 0.979 (R2 = 0.89, p < 0.001 for paraoxon); y = 0.120 x - 6.57 (R2 = 0.82, p < 0.005 for parathion). No difference was observed between the two organophosphates. After treatment with the cytochrome P450 inhibitor piperonyl butoxide, the above relations ceased to apply, but this treatment did not influence the kinetics of paraoxon and parathion uptake. The IC50 value calculated for paraoxon, i.e., the paraoxon concentration required to produce 50% inhibition of lung cholinesterase activity, was similar for guinea pigs (2.22 10(-7) +/- 0.22 M) and rabbits (2.36 10(-7) +/- 0.24 M). In conclusion, the biexponential evolution of the velocity of paraoxon and parathion uptake by the lungs thus demonstrates the presence of two pools. The lower extraction ratios calculated for rabbit lungs reflect the lower initial uptake velocity of the second compartment. In the range of concentrations investigated in guinea pigs, no saturable mechanism could be demonstrated for paraoxon and parathion. Cytochrome P450-related lung metabolic activity, through which parathion is converted to paraoxon, appears as a major step in parathion-induced lung cholinesterase inhibition, although it does not appear to affect parathion toxicokinetics [less ▲]

The present research examines how the social identity perspective contributes to a better understanding of the relationships between perceived organizational support, affective commitment, and employees’ performance at work. Using a sample of 253 employees from an engineering company, Study 1 found that organizational identification partially mediates the relationship between perceived organizational support and affective commitment. The results of Study 1 also indicated that the relationship between perceived organizational support and organizational identification is moderated by organizational prestige. In Study 2, using a sample of 179 postal employees, the authors replicated the mediating role of organizational identification in the relationship between perceived organizational support and affective commitment and found that affective commitment mediates the relationship between organizational identification and supervisor’s ratings of extra-role performance.
