Zinc Chloride Reverse Influence on Dexamethasone Depressant Effects in Adult Male Rats

Background: Cumulative evidence shows that dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis is involved in the depressive disorders and natural or synthetic glucocorticoids have a direct effect on HPA activity. Objectives: Considering the reports that show zinc deficiency is one of the causes of depressive-like behavior, the current study aimed to examine the effects of systemic injection of zinc chloride (ZnCl 2 ) and/or dexamethasone sodium-phosphate (DEX) on depression in adult male rats. Materials and Methods: Different groups received ZnCl 2 (2.5, 5, 10, and 20 mg/kg) and DEX (0.5, 1, 5, 10, and 30 mg/kg) and then depression was assessed in the forced swimming test (FST). Results: Results showed that DEX 1 significantly increased, while DEX 30 and groups treated with zinc 10 mg/kg and zinc 20 mg/kg decreased total immobility time as compared to that of saline group. Also there was a significant decrease of total immobility time when zinc administered to rats already received DEX 1, compared with that of control group. Conclusions: The current study findings suggest that zinc has antidepressant effects dose dependently, while administration of DEX induced dual effects on depression; therefore, a low dose of DEX showed an increased level of depressive-like behavior while higher doses had antidepressant effects. Also, results showed that zinc administration could ameliorate depressive-like behavior induced via dexamethasone in FST.
Virtualization of Behaviours of Young Consumers

Virtualization of consumption represents satisfying needs by means of electronic media, mainly by the Internet and television [Bywalec 2007]. Patrzałek [2004, p. 34] emphasises that virtualization favours growth of importance of indirect communication against direct relationships, and gradual decline of direct buying for the benefit of online buying. Having the access to the Internet on mobile phones is the expression of technology development, a proof of life being dominated by the Internet and contemporary consumers’ pursuit of being online all the time. The market of teenagers is currently observing the highest value over several recent years [Lindstom 2003], and a considerable part of expenses is intended for the purchase of mobile phones and their usage [Quart 2003]. The way young people use mobile phones has been the subject of many international [Wilska 2003; GSMA, 2012], as well as regional research [Torlak et al. 2011; Alt and Pal 2011; Ofcom, 2015], including Polish studies [UKE, 2012; Dębski 2016].

Proposal of a fault estimation using coprime fractions

detection, diagnostic and fault isolation systems FDD generate signals (residuals) containing details of the fault. The state estimation is a common procedure for residual generation when it used analytically. In this article, the proposed hypothesis is to use the theory of coprime fractions to generate an estimator of the output; it competes with some classic Kalman, Luenberger, Lyapunov and Jordan estimators and thus analyses their execution times and accuracy rates by the mean square error in presence of additive failures. The results are validated on a FDD system implemented on a homogenization tank in a closed loop using the standard process control OPC and physically simulating a sensor fault in a RTD.
Learning to Lead: What Gets Taught in Principal-Preparation Programs1

Today, school principals are asked to lead in a new world marked by unprecedented responsibilities, challenges, and managerial opportunities. Are principal preparation programs equipping their students for this new role? This study examines the content of instruction at a stratified sample of the nation's principal preparation programs. The analysis looks at preparation at the programs training the most candidates, the programs regarded as most prestigious, and more typical programs. We surveyed 56 programs and were able to collect 31 sets of syllabi that met the standards permitting systematic coding. The syllabi yielded 2,424 course weeks in the 210 syllabi analyzed. Overall, we found surprising similarities across the various types of programs. Just 2% of course weeks addressed accountability in the context of school management or school improvement. Eleven percent of course weeks made reference to statistics, data, or empirical research in some context. Only 12% of course weeks focused upon norms and values, but within those weeks there was evidence of normative bias in the topic descriptions and assigned readings. The evidence raises questions about whether principal preparation has kept pace with changes in the larger world of schooling.
Characterization of Nanocrystalline Cu25Mo Electrical Contact Material Synthesized via Ball Milling

In this study, Cu-based Mo-doped composite powder was synthesized by ball milling technique. Elemental powder mixture containing 25 wt. % Mo was milled in a high-energy planetary-type ball mill to achieve homogeneously mixed composite powder. Characterization of the starting and the milled powders was carried out using scanning electron microscopy and laser diffraction analysis. It was found that particle size of powder had gradually decreased with increasing milling duration. scanning electron microscope pictures, corresponding to the later stages of milling process prove that nanocrystalline powders were obtained after milling duration of 30 h. Prolonged milling durations lead to powder contamination, which is undesirable for contact applications, where the purity is of big importance. Therefore, optimum milling duration was determined to be 30 h.
Selection of maternal lines: last results and prospects.

The aim of this review is to discuss selection of maternal lines, to present last results and to draw research prospects. Firstly, we discuss the genetic variability of the maternal quality traits. A divergent selection experiment on uterine capacity was performed in Spain during eight generations; results put forward the hypothesis that there was a major gene affecting uterine capacity. Reproductive performance could be improved by including female fertility in a selection program but response to selection would be probably very low. Even if genetic correlation between prolificacy traits and growth traits are, in general, positive, the litter size effect, introduced in the statistical models of growth traits, is always highly significant and negative, showing the well known phenotypic relationship between litter size and weights. One spreading method for analysing female longevity data is survival analysis which allows inclusion of both censored and uncensored records of animals. Development of computer programs has made it possible to estimate the genetic potential of does for a longer productive life and to the genetic parameters for longevity. Studies have been conducted to settle adequate models of analysis and this criterion could be included in the selection objective. Later we draw up an inventory of the 19 on going selection experiments in six different countries. Significant differences in direct genetic effects for litter size or litter weight were found. An alternative to the selection of maternal lines for crossbreeding could be the development of a multi-purpose line, through simultaneous selection for litter size and growth traits. Finally we propose some conclusions. Selection objectives of maternal lines were directed towards a new direction: productivity is always a main point but breeding has to be sustainable. Therefore, we have to reduce young rabbits mortality, to increase doe longevity and to maintain genetic variability in selected lines.
Effects of Video Display Terminal Resolutions to the Legibility of Text on a Web Page

Higher Video Display Terminal (VDT) resolutions have been proven to provide better quality in improving image quality displayed. The higher the resolution means more pixels per-inch-square available to display an image. This increase, however, may not be to the fonts used on web pages for improved legibility. Legibility of web text has been proved essential to ensure the quality of a web page. Support by the evidence from the previous research experiment results; low level of web text legibility can cause various visual related problems and usability of a web page. This research will focus on finding possible improvement effects on VDT resolution that might need to be considered in designing the web text. In this research 6 font types and two VDT resolutions for low and high have been selected. Approximately 200 subjects were randomly selected for this experiment. The selected subjects were divided into two groups for low and high resolution. Selected subjects performed legibility test and subjective preference test experiments on 6 selected type of fonts. Overall findings indicate that there is an improvement but no significant difference between the two VDT resolutions. Keywords: Legibility; Web text; Video Display Terminal; Fonts; Resolutions
Potential Outcomes and Consequence of a Proposed Grazing Permit Buyout Program

Abstract This study investigated the role that a public land grazing permit buyout would have on ranching operations and conserving private land open space in the Rocky Mountain region of the western United States. Loss of grazing permits could serve as a pivotal factor in expediting private land fragmentation if ranching operations are enticed to sell their land due to loss of economic viability. This type of program inadvertently could be detrimental to overall ecosystem health and have unintended economic, ecological, and cultural consequences for the administering agencies and grazing permittees. The goal of this study was to provide sociodemographic profiles of landowners to better understand social motivations for ranching, implications of permit removal, ongoing conservation activities, and possible policy solutions. We assessed likely participation levels, demographic attitudes, and reasons for participation in a proposed grazing permit buyout program. This paper is based on data collected from a mail survey of 2 000 permittees in the Rocky Mountain States (39% response rate), and data collected from qualitative personal interviews. These interviews assessed motivations for participation, potential costs, and search for unforeseen consequences related to a proposed buyout program. We interviewed 49 individuals (33 ranchers, 16 agency personnel), which enabled us to describe likely outcomes and previously unmentioned items for consideration related to a proposed buyout program. Interview data were analyzed and broken into two major themes: motivation for participation in a buyout and potential consequences. Our study indicated that overall participation in potential buyout would be relatively low (17%); however, the associated financial, ecological, and administrative costs could be substantial. We note several unanticipated motivations for possible participation in this type of program, as well as possibly unrecognized impacts for administering agencies and permittees.
SCALE-UP Instructional Redesign of a Calculus Course at an HBCU

It is now generally accepted that many students enter college severely underprepared for their mathematics college courses in terms of basic skills and study habits, and that intervention is expected to overcome these deficiencies. As a result, many mathematics departments nationwide have over the last two decades redesigned their algebra and calculus courses to incorporate technology and active learning in various combinations, some of which have utilized extensive learning space designs. This article is a preliminary report of one Historically Black College or University’s (HBCU) experience with its redesign of the first semester of Calculus for STEM Majors that resulted in a course-wide partial implementation of the Student-Centered Active Learning Environments with Upside-down Pedagogies (SCALE-UP) method. Preliminary results show that the redesign, enabled by institutional and external resource coordination, has led to moderate improvements in course pass rates, from a normal of 40% and below to a new normal of above 50%. The pass/fail student profile suggests that weakness in pre-requisite skills is a major cause of failure.
Occurrence and pathogenicity of Candida spp. in unpasteurized cheese

Occurrence and Pathogenicity of Candida spp. in Unpasteurized Cheese). The aim of this study was to assess the prevalence and pathogenicity of the most common species of the genus Candida isolated from artisanal cheese produ- ced in a city, in in Santa Catarina countryside. A total of 251 strains of Candida were isolated, with growth capacity at 37 °C, from the analysis of 45 artisanal cheese samples. Of these, 2.4% were identified as C. albicans and 97.6% as Candida non-albicans, which were distributed in 79.3% of C. krusei, 12.3% of C. glabrata and 6.0% C. tropicalis. Regarding to the activity of the proteinase enzyme, the production was observed in 0.8% of the samples. About 0.4% of yeast isolates showed strong production of biofilm on polystyrene screening test. According to this data, it was found a large prevalence of non- -albicans Candida isolated in artisanal cheese with potential capacity for development and colonization due to the human body temperature.
On assessing the robustness of an input signal optimization algorithm for damage detection: the Info-Gap Decision Theory approach

The Info-Gap Decision Theory (IGDT) is here adopted to assess the robust- ness of a technique aimed at identifying the optimal excitation signal within a structural health monitoring (SHM) procedure. Given limited system response measurements and ever-present physical limits on the level of excitation, the ultimate goal of the mentioned technique is to improve the detectability of the damage increasing the difference between measurable outputs of the undamaged and damaged system. In particular, a 2 DOF mass- spring-damper system characterized by the presence of a nonlinear stiffness is considered. Uncertainty is introduced within the system under the form of deviations of its parameters (mass, stiffness, damping ratio.) from their nominal values. Variations in the performance of the mentioned technique are then evaluated both in terms of changes in the estimated difference between the responses of the damaged and undamaged system and in terms of deviations of the identified optimal input signal from its nominal estimation. Finally, plots of the performances of the analyzed algorithm for different levels of uncertainty are ob- tained, showing which parameters are more sensitive to the presence of uncertainty and thus enabling a clear evaluation of its robustness.

Packaging-compatible high Q microinductors and microfilters for wireless applications

To meet requirements in mobile communication and microwave integrated circuits, miniaturization of the inductive components that many of these systems require is of key importance. At present, active circuitry is used which simulates inductor performance and which has high Q-factor and inductance; however, such circuitry has higher power consumption and higher potential for noise injection than passive inductive components. An alternate approach is to fabricate integrated inductors, in which lithographic techniques are used to pattern an inductor directly on a substrate or a chip. However, integrated inductors can suffer from low Q-factor and high parasitic effects due to substrate proximity. To expand the range of applicability of integrated microinductors at high frequency, their electrical characteristics, especially quality factor, should be improved. In this work, integrated spiral microinductors suspended (approximately 60 /spl mu/m) above the substrate using surface micromachining techniques to reduce the undesirable effect of substrate proximity on the inductor performance are investigated. The fabricated inductors have inductances ranging from 15-40 nH and Q-factors ranging from 40-50 at frequencies of 0.9-2.5 GHz. Microfilters based on these inductors are also investigated by combining these inductors with integrated polymer filled composite capacitors.

Microsatellite markers based genetic diversity analysis in Damani and Nachi goat breeds of Pakistan.

Received: Revised: Accepted: July 13, 2012 April 19, 2013 June 20, 2013 The genetic variation in two indigenous Pakistani goat breeds (Damani and Nachi) was studied with 9 microsatellite markers in order to determine the genetic diversity between them. A total number of 50 non relative individuals of Damani (25) and Nachi (25) were sampled to explore genetic polymorphisms and relationship between these two important goat breeds. Result revealed considerable level of genetic diversity in both breeds and a total number of 53 alleles were identified with mean of 3.2 in Damani and 4.6 in Nachi. The genetic diversity in both breeds ranged from 0.51(Nachi) to 0.73 (Damani). High level of genetic differentiation (FST = 0.20) and low level of gene flow (Nm=0.95) found could be due to their divergent or expanded geographical locations. Heterozygote across two populations (FIT) was found to be 0.15. The mean Polymorphic Information Content (PIC) was 0.70 ranging from 0.54 (MAF33) to 0.83 (ILSTS011), revealed the high level of polymorphism for studied microsatellite markers set in this study. The measures of genetic variation revealed that there is good scope for effective improvement, conservation and designing national breeding policies for goat breeds in future. ©2013 PVJ.

Childhood malaria: mothers' perception and treatment- seeking behaviour in a community in Ebonyi State, South East Nigeria

Context: Childhood malaria continues to be a major cause of childhood morbidity and mortality. Caregivers ability to detect the illness in children early and institute effective treatment is critical to illness outcome. The investigation of mothers\' perception of malaria and treatment-seeking behaviour in childhood malaria in a community in Ebonyi State, South-East Nigeria was therefore the aim of this study. Methods: Using a cross-sectional descriptive study design, interviewer-administered structured questionnaires were administered to a sample of 236 mothers drawn by multi-staged sampling to collect information on their perception of and recognition of signs and symptoms of malaria in children and treatment-seeking behaviour. Findings: The mean age of the respondents was 40.63 years. Only 35.2% of them knew the cause of malaria. No significant association was found between education and this knowledge. Majority (59.3%) of the respondents perceived malaria as a serious problem. Fever and chills were the most common symptoms recognised by 72% and 60.2% of the mothers respectively as being associated with malaria in children. The incidence of history of fever, indicative of malaria in children of the respondents within one month of the survey was 74.6%. The health centre was the most preferred choice where treatment was first sought (21%) for the bout of fever while government hospitals and community health workers were sources of treatment for 15.9% and 14.6% respectively. Other sources of treatment were treatment at home, patent medicine dealers, private hospital and traditional healers used by 13.6%, 10.2 % and 7.4% respectively. The dominant reasons for choice of the health centre were availability of Doctor / trained personnel (73%) and good service (67.6%). Proximity was the major factor (92.3%) for choice of the community health workers. Low cost of care and good personal experience were the main reasons for the choice of traditional healers and home treatment respectively. The mean number of days between when illness was noticed and time treatment was instituted was 3 days. Conclusion: The low level of awareness of mothers of the cause of malaria, the poor treatment-seeking behaviour shown by the low level of use of the health facilities as a place where treatment is first sought, and the delay in seeking treatment for childhood malaria, suggest a need for intensified health education intervention programmes. Measures to relieve poverty and reduce cost of allopathic care should also be put in place.

Automatic Information Processing Bias to Stress Factors by Older Adults with and without Diabetes

A sample of 65 older adults (with and without diabetes) as well as a sample of 84 healthy young people were required to take affective priming studies to compare recognition latencies of stress related word pairs against recognition latencies of positive, negative and neutral word pairs. Moreover, older adults took a stress questionnaire related to relevant disturbing events in the third age. The goal was to test any automatic emotional processing bias to these events. Results suggested that even when people with diabetes obtained low stress test scores, they showed automatic cognitive bias to process stressful events differently than older adults without diabetes and young people. This suggested that people with diabetes patients’ controlled strategies to cope with stress might not be aware of such an automatic cognitive bias. It is argued that this information processing style to stressful events makes patients prone to cognitive emotional vulnerability.
