Predictors of initiation and persistence of recurrent binge eating and inappropriate weight compensatory behaviors in college men.

OBJECTIVE The transition to college is considered as a risk period for the development of behavioral symptoms of eating disorders (BSEDs) and some evidence suggests that, amongst men, these symptoms occurring on a regular basis remain relatively stable over the college period. Nevertheless, little is known about factors associated with persistent engagement in and initiation of recurrent (or regular) binge eating and inappropriate weight compensatory behaviors in this population. The objective of this report was to address these research gaps. METHOD Data were examined from 2,555 male first-year college students who completed an assessment of potential vulnerability factors and BSEDs at the beginning of the autumn semester (baseline) and nine months later (end of the spring semester; follow-up). RESULTS Elevated negative affectivity, body dissatisfaction, self-objectification, and lower self-esteem at baseline were predictive of persistent engagement in regular binge eating and four compensatory behaviors (self-induced vomiting, laxative/diuretic abuse, fasting, exercise) at follow-up, as well as initiation of all these behaviors occurring regularly (i.e., at least weekly for 3 months). Self-objectification (thinking and monitoring the body's outward appearance from a third-person perspective) emerged as the largest contributor of both the initiation and persistence of all behavioral symptoms. DISCUSSION Data emphasize that the same psychological factors underlie initiation and persistence of recurrent BSEDs and should shape the focus of future interventions for college men. © 2016 Wiley Periodicals, Inc.

Design of Pixel Circuits for Blue-Phase Liquid Crystal Displays

This work reviews pixel circuits for blue-phase liquid crystal displays (BPLCDs) and presents two novel pixel circuits for the BPLC. With respect to the high-operating-voltage BPLC, the first developed pixel circuit comprises practical source driver integrated circuits (ICs) and an additional signal with three voltage levels to widen the voltage range from a data line in order to enable the BPLC to achieve high transmittance. For the low-operating-voltage BPLC with a large dielectric anisotropy, the second pixel circuit boosts the gate voltage of the switch thin-film transistor (TFT) to enhance its driving capability to deal with the large equivalent capacitance of the BPLC. Simulation results verify the functions of both new pixel circuits with Full High Definition (FHD, 1920 ×1080) resolution and a frame rate of 120 Hz.
Population dynamics of and larval trematode interactions with Lymnaea tomentosa and the potential for biological control of schistosome dermatitis in Bremner Bay, Lake Wanaka, New Zealand

Abstract Lymnaea tomentosa, the intermediate host of a schistosome which causes schistosome dermatitis in Lake Wanaka, was found to depths of 16 m. The snail recruits in January, lives for up to 21 months, is associated with all water plant species and is found in areas devoid of macroscopic plants. It is host to several trematode species. Avian schistosome infections appear in the spring when echinostome prevalence is low, and a decrease in schistosome prevalence may be correlated with an increase in echinostome prevalence during the summer. A multiple-kind lottery model analysis of parasite species richness implies that interspecific interactions may be occurring in the host snail during the months of December and January.
Frequent expression of P‐glycoprotein/MDR1 by nasal T‐cell lymphoma cells

Background. Lethal midline granuloma is now considered to be a malignant lymphoma derived from peripheral T cells or from natural killer cells. The therapeutic outcome of nasal T‐cell lymphoma (NL) treated by conventional chemotherapy for non‐Hodgkin's lymphoma is poor, although some patients have a good response to radiotherapy. To clarify the mechanisms of drug resistance, the expression of P‐glycoprotein (P‐gp)/MDR1, which is the product of the multidrug resistance (MDR) 1 gene, and MDR3 mRNA in NL cells, were examined.
Vitamin B12 and Folate Status in Sudanese Psychiatric Patients

Background: The contribution of B12 and folate deficiencies to pathophysiology of psychiatric illnesses is well known worldwide, however it was not evaluated in Sudanese psychiatric patients. Aim: To assess the association between the neuropsychiatric syndromes and the levels of both vitamin B12 and folic acid in Sudanese psychiatric patients. Materials and Methods: The study involved a test group of 100 psychiatric patients and an age/gender matched control group of 100 subjects with no past history of psychiatric illness. Laboratory investigations, including complete blood count (CBC), serum vitamin B12 and folate concentrations were done to all studied subjects. Significance of the difference in the means of the studied variables and the association between psychiatric illnesses and both B12 or folic acid deficiencies were assessed using appropriate statistical tests. Results: Most of hematological indices were significantly less in psychiatric patients, although their means were within normal range. The serum concentrations of vitamin B12 in the psychiatric patients (M±SD = 527.9 ± 305. 8 pg/ml) were significantly lower compared with the control group (M±SD = 590.5± 186.1 pg/ml, P = 0.001). There was significant association between B12 deficiency and psychiatric illnesses (P = 0.014). Six percent of the psychiatric patients were suffering from B12 deficiency while none the control group was suffering from the same deficiency. The serum concentrations of folic acid were comparable in both studied groups (M±SD = 7.2 ± 1.7 ng/ml, 7.2 ± 2.6 ng/ml in the control and test groups respectively, P > 0.05). There was no folic acid deficiency in both test and control groups. Conclusion: There was association between vitamin B12, but not folic acid, deficiency and psychiatric diseases in studied Sudanese subjects. Most of the hematological indices were significantly less in psychiatric patients, although their means were within normal range. The significantly lower levels of vitamin B12 deficiency were not associated with megaloblastic changes.
Response to fluorouracil therapy in cancer patients: the role of tumoral dihydropyrimidine dehydrogenase activity.

PURPOSE The aim of the present study was to analyze the role of thymidylate synthase (TS; main cellular target of fluorouracil [FU]) and dihydropyrimidine dehydrogenase (DPD; rate-limiting enzyme of FU catabolism) in tumoral biopsies with respect to FU responsiveness. PATIENTS AND METHODS This prospective study was conducted on 62 head and neck cancer patients (six stage II, 16 stage III, and 40 stage IV). All received first-line chemotherapy with biomodulated FU (5-day continuous infusion). Before treatment, a tumor biopsy and control biopsy (symmetrical nontumoral area) were obtained. Cytosolic TS and DPD activities were measured using radioenzymatic assays. RESULTS DPD activity was detectable in all samples, without a significant difference between tumoral (median, 60 pmol/min/mg protein; range, 13 to 193) and nontumoral samples (median, 68 pmol/min/mg protein; range, 12 to 150). Tumoral TS and tumoral DPD were not significantly influenced by tumor localization or tumor staging. Among 52 tumors assessable for clinical response, we observed 46% complete responses (CRs), 33% partial responses (PRs), and 21% no responses (NRs). No relationship was demonstrated between TS activity and response to FU therapy. The comparison of tumoral DPD between complete responders and partial or nonresponders showed a trend toward significance (P = .06). In an attempt to reduce variability, we analyzed the tumoral/nontumoral DPD activity ratio; complete responders exhibited a significantly lower normalized DPD than partial or nonresponding patients (median, 0.86, 1.18, and 1.42 for CR, PR, and NR, respectively; CR v PR plus NR, P = .03). CONCLUSION Although resistance to FU is multifactorial, the present clinical study suggests that FU catabolism in target cells is probably a determinant factor for FU responsiveness in cancer patients and justifies the clinical use of specific DPD inhibitors as FU biomodulators.
Diarylpropanoids from nutmeg and mace (Myristica fragrans Houtt.).

Some diarylpropanoid (bis-C6–C3) type compounds have been isolated during the course of a search for the psychoactive components present in the seed (nutmeg) and aril (mace) of the fruit of Myristica fragrans Houtt. The presence of two different structural types, analogous to the β-O-4 ether and 2,3-dihydrobenzofuran types of dilignols, has been established. Six examples (I)–(III) and (V)–(VIII) of the former type and two of the latter, dehydrodi-isoeugenol (IX) and 5-methoxydehydrodi-isoeugenol (X) have been isolated and their structures established. Compounds (I), (II), and (V), have been synthesised and the relative configuration of the β-O-4 ethers has been established as erythro.
Effects of methylene blue stabilizer on in vitro viability and chemotaxis of 99mTc-exametazime-labeled leukocytes.

UNLABELLED This study was conducted to evaluate the effects of methylene blue/phosphate buffer stabilizer on the labeling efficiency, cell membrane integrity, chemotaxis, and in vitro stability of leukocytes labeled with 99mTc-exametazime. METHODS Whole blood (480 mL) was obtained from each of 3 healthy donors and divided equally into eight 60-mL aliquots. Two aliquots from each of the 3 subjects were used as a control (i.e., leukocytes were not labeled with either nonstabilized or stabilized 99mTc-exametazime) in this study. The remaining 6 aliquots from each of the 3 subjects were divided equally into the following formulation groups: (a) leukocytes labeled with nonstabilized 99mTc-exametazime, (b) leukocytes labeled with stabilized 99mTc-exametazime containing 250 microg methylene blue, and (c) leukocytes labeled with stabilized 99mTc-exametazime containing 500 microg methylene blue. Duplicate samples were evaluated to confirm the repeatability of the study. Six samples were studied under each experimental condition (i.e., control, a, b, and c groups). The cell membrane integrity and chemotatic capacity of leukocytes were measured at 1 and 3 h after preparation, whereas a complete blood count was obtained at 3 h after preparation. The labeling efficiency was calculated immediately on conclusion of cell labeling, whereas the in vitro stability of the radiolabeled leukocytes was evaluated at 3 h after radiolabeling. RESULTS None of the samples showed trypan blue-stained cells. For the chemotactic index, no statistically significant differences were noted between the 3 labeling formulations at 1 h (P = 0.43) or 3 h (P = 0.10) after preparation. None of the labeling formulations differed significantly from the control values of the chemotactic index (all P > 0.25). For the complete blood count, no significant differences were observed between any of the groups, with the exception of platelet number in the control group (P = 0.004). The labeling efficiency (P = 0.10) and in vitro stability (P = 0.33) were also similar in our comparison of the 3 labeling formulations. CONCLUSION With no major statistically significant difference noted either between the 3 labeling formulations or between the control and the 3 labeling formulations, we concluded that the methylene blue/phosphate buffer stabilizer (250 or 500 microg methylene blue) did not affect the cell membrane integrity, chemotactic capacity, labeling efficiency, in vitro stability, or complete blood count of leukocytes labeled with stabilized 99mTc-exametazime.
Dominance Violations and Event Splitting in Decision under Uncertainty *

A standard requirement of rationality is that preferences obey stochastic dominance. In this paper, we investigate a new variety of dominance violation from the domain of uncertainty. We find that subjects systematically value a packed prospect, $x if one of two mutually exclusive events E1 or E2 obtains, less than an unpacked and dominated prospect, $x if E1 obtains, and $x−ε if E2 obtains. We account for these violations in terms of subadditivity of probability judgments (Tversky and Koehler, 1994): unpacking an event into constituent components increases the total probability assigned to that event. We discuss the implications of these dominance violations for composition rules in prospect theory.
Automaticity, Consciousness and Moral Responsibility

Cognitive scientists have long noted that automated behavior is the rule, while conscious acts of self-regulation are the exception to the rule. On the face of it, automated actions appear to be immune to moral appraisal because they are not subject to conscious control. Conventional wisdom suggests that sleepwalking exculpates, while the mere fact that a person is performing a well-versed task unthinkingly does not. However, our apparent lack of conscious control while we are undergoing automaticity challenges the idea that there is a relevant moral difference between these two forms of unconscious behavior. In both cases the agent lacks access to information that might help them guide their actions so as to avoid harms. In response, it is argued that the crucial distinction between the automatic agent and the agent undergoing an automatism, such as somnambulism or petit mal epilepsy, lies in the fact that the former can preprogram the activation and interruption of automatic behavior. Given that, it is argued that there is elbowroom for attributing responsibility to automated agents based on the quality of their will.
A Comparison of Salary-Wage and Hourly-Wage Acute Care Nursing Units: A Pilot Study

OBJECTIVE: This pilot study examined differences in RN perception of the professional practice environment and financial indicators between salary-wage and hourly-wage compensation models. BACKGROUND: There is a dearth of current information regarding use of salary-wage models for compensation for direct care nurses. METHODS: A descriptive, comparative design was used to examine the Revised Professional Practice Environment Scale (RPPE) and financial indicators of nurses in a nonprofit healthcare system over a 6-month period. RESULTS: Mean scores on the RPPE were significantly lower for hourly-wage RNs, and the hourly-wage model resulted in a 1.2% additional cost for overtime hours compared with the fixed cost of the salary-wage model. CONCLUSIONS: Nurses in an hourly-wage unit reported a significantly lower perception of the clinical practice environment than did their peers in a salary-wage unit, indicating that professional practice perceptions in a salary-wage unit may provide a more effective professional practice environment. Financial analysis resulted in a budget-neutral impact.
The Impact of Simulation on Pediatric Nursing Students’ Knowledge, Self-efficacy, Satisfaction, and Confidence

The simulation technology is rapidly expanding and has been used in several nursing programs around the world and in Saudi Arabia too. The aim of this study was to evaluate the effect of using a simulation based scenarios on the pediatric nursing students’ students’ knowledge, self-efficacy, satisfaction, and confidence. This study used Bandura’s Social Cognitive Learning Theory (1977; 1986) as a theoretical framework.158, third year baccalaureate nursing students enrolled in a pediatric nursing course participated in the study. Data was collected using demographic data profile questionnaire, knowledge questionnaire, Learner Satisfaction and Self Confidence in Learning Questionnaire (NLN, 2009) and the General Self-Efficacy.The simulation activities were conducted in the pediatric nursing lab. The simulation activities consisted of three respiratory problems and one cardiac scenario. High and low fidelity simulators were used. The majority of the students were unmarried (96.84%) and had no previous experience in simulation. There was a significant statistical difference in pre- and posttest knowledge and self-efficacy scores. Students were satisfied with the simulation experience and their self-confident scores were higher after the simulation session. That post simulation self-efficacy was positively correlated with satisfaction (r= .46, P = 0.001) and self-confidence (r= .50, P = 0.001). Satisfaction with simulation was also positively correlated with self-confidence (r = 0.46, P = 0.001). Although the interpretation of the study results is limited due to the short time frame between the pretest and the posttest, this study provides a stepping point for understanding how simulation may affect the pediatric nursing students’ knowledge, self-efficacy and confidence.

Association of snoring with chronic bronchitis.

BACKGROUND Snoring is more prevalent in patients with chronic bronchitis than in persons without it. Few studies have examined the effect of snoring on chronic bronchitis. We prospectively investigated the association between snoring and the incidence of chronic bronchitis. METHODS The baseline study was conducted from June 25, 2001, to January 29, 2003. Members of the study cohort consisted of 5015 male and female Korean citizens aged 40 to 69 years at baseline who participated in a comprehensive health examination and on-site interviews at Korea University Ansan Hospital. Of these, 4270 participants (52% men and 48% women) entered the analysis for the first 2-year follow-up from April 17, 2003, to February 20, 2005, and those who met the same inclusion criteria remained in the analysis for a second 2-year follow-up period from February 21, 2005, to November 17, 2006. We collected information on snoring at baseline and identified incident cases of chronic bronchitis during a 4-year follow-up period. On the baseline questionnaire, we excluded participants who reported the presence of cough and sputum production on most days for at least 3 months a year. RESULTS During 4 years of follow-up, we documented 314 cases of new-onset chronic bronchitis (27.1 cases per 1000 person-years). After taking into account age, smoking, and other risk factors for chronic bronchitis, the multivariate relative risks of chronic bronchitis were 1.25 (95% confidence interval [CI], 0.95-1.64) for persons snoring 5 times per week or less and 1.68 (95% CI, 1.17-2.42) for those snoring 6 to 7 times per week compared with never snorers (P for trend = .049). The analyses stratified by risk factors, including smoking, occupation, and body mass index, showed a stronger association among never smokers, house workers, and overweight persons. In analysis for the joint effect of smoking and snoring, the relative risks of chronic bronchitis were 1.39 (95% CI, 1.01-1.90) for nonsmoking and snoring, 2.31 (95% CI, 1.38-3.87) for smoking and never snoring, and 2.86 (95% CI, 1.91-4.27) for smoking and snoring compared with nonsmoking and never snoring. CONCLUSIONS This prospective study observed that snoring is associated with chronic bronchitis. Our findings provide support for the hypothesis that snoring influences the development of chronic bronchitis.
Dynamics of Work Limitation and Work in Australia

This paper examines the impact of self-reported work limitations on the labour force participation of the Australian working age population. Five consecutive waves of the Household, Income and Labour Dynamics in Australia (HILDA) Survey are used to investigate this relationship. A two-equation dynamic panel data model demonstrates that persistence and unobserved heterogeneity play an important role in work limitation reporting and its effect on labour force participation. Unobserved factors that jointly drive work limitation and participation are also shown to be crucial, especially for women.
Does net energy cost of swimming affect time to exhaustion at the individual's maximal oxygen consumption velocity?

AIM The purpose of the present study was to examine the relationship between time limit at the minimum velocity that elicits the individual's maximal oxygen consumption (TLim-v VO2max) and three swimming economy related parameters: the net energy cost corresponding to v VO2max (Cv VO2max), the slope of the regression line obtained from the energy expenditure (E) and corresponding velocities during an incremental test (C(slope)) and the ratio between the mean E value and the velocity mean value of the incremental test (C(inc)). Complementarily, we analysed the influence of Cv VO2max, C(slope) and C(inc) on TLim-v VO2max by swimming level. METHODS Thirty swimmers divided into 10 low-level (LLS) (4 male and 6 female) and 20 highly trained swimmers (HTS) (10 of each gender) performed an incremental test for v VO2max assessment and an all-out TLim-v VO2max test. RESULTS TLim-v VO2max, v VO2max, Cv fVO2max, C(slope) and C(inc) averaged, respectively, 313.8+/-63 s, 1.16+/-0.1 m x s(-1), 13.2+/-1.9 J x kg(-1) x m(-1), 28+/-3.2 J x kg(-1) x m(-1) and 10.9+/-1.8 J x kg(-1) x m(-1) in the LLS and 237.3+/-54.6 s, 1.4+/-0.1 m x s(-1), 15.6+/-2.2 J x kg(-1) x m(-1), 36.8+/-4.5 J x kg(-1) x m(-1) and 13+/-2.3 J x kg(-1) x m(-1) in the HTS. TLim-v VO2max was inversely related to C(slope) (r = -0.77, P < 0.001), and to v VO2max (r = -0.35, P = 0.05), although no relationships with the Cv VO2max and the C(inc) were observed. CONCLUSIONS The findings of this study confirmed exercise economy as an important factor for swimming performance. The data demonstrated that the swimmers with higher and v VO2max performed shorter time in TLim-v VO2max efforts.
Competing interactions in molecular adsorption: NH3 on Si(001)

Ammonia is a good model system for the study of co-adsorption interactions, including indirect effects such as charge and strain-induced local effects on adsorption sites, and direct interactions such as hydrogen bonding. On the Si(001) surface, it adsorbs molecularly, via a dative bond from the N atom to the down atom of a buckled dimer, and is therefore very sensitive to the local charge conditions. It will then dissociate into –H and –NH2 groups, adsorbed on the dangling bonds of the Si dimers. The NH2 groups do not diffuse, so any correlations deriving from interactions during adsorption are preserved, and can be derived by analysis of the arrangements of the NH2 groups. Hydrogen-bonding interactions are crucial in understanding the behaviour of this system, with significant co-adsorption interactions occurring both along and across rows, outweighing the electrostatic or buckling-related effects. In recent years, there have been several scanning tunnelling microscopy studies and extensive computational modelling of the NH3 on Si(001) system, attempting to determine a dominant mechanism governing co-adsorption effects. In this review, I will discuss both experimental and theoretical results, make a comparison with similar molecules such as phosphine (PH3), and review the different ways in which experimentalists and modellers have approached this complex system.
