The purpose of this study was to determine whether heterozygosity (assessed using microsatellite genotypes) was correlated with the body weight of heifers from birth to 18 months. The study was conducted on the heifers’ herd of the Taurian intra-breed type Southern meat cattle breed at Askaniiske State Research Enterprise (Ukraine, Kherson Region). During the study, we used ten microsatellite loci recommended by International Society for Animal Genetics (ISAG) TGLA227, BM2113, TGLA53, ETH10, SPS115, TGLA122, INRA023, BM1818, ETH3 and BM1824. The heifer’s body weight was measured at birth, at weaning, and at the age 8, 12, 15 and 18 months. Individual heterozygosity estimates (for each microsatellite loci separately) and microsatellite multilocus heterozygosity (for all used loci) estimates (MLH) were used in the analysis. ANOVA was used to determine the relationship of the dependent effects (body weight at different ages) to single locus heterozygosity using two classes: 0 (for homozygous individuals) and 1 (for heterozygous individuals). In addition, the following indicators were calculated for each genotype: the squared distances (d2) between the length of both alleles within the individual genotype for each microsatellite loci, as well as the mean squared distance (multilocus d2) between the lengths of both alleles within the individual genotype for ten microsatellite loci. Spearman’s rank correlation coefficients were used to measure the association between d2 scores (for each microsatellite loci) and body weight at different ages. The influence of different grades of estimates of MLH and mean d2 classes was also assessed based on ANOVA. Heterozygosity at locus BM2113 was significantly (P < 0.01) associated with heifer’s body weight at the age of 15 months and heterozygosity at locus BM1818 was significantly (P < 0.05) associated with heifer’s body weight at the age of 8 months. Significant Spearman’s rank correlations (P < 0.01...0.05) were also observed between the body weight and d2 score for four microsatellite loci BM2113, SPS115, ETH3 and BM1824. Individual mean heterozygosity estimates for 10 microsatellite loci and mean d2 estimates were weakly associated with weight performance in Southern meat cattle breed heifers.

Introduction: The nurse, in addition to nurture the patient should shape his awareness of a healthy lifestyle. The aim of the research was to analyze the health behaviors of nurses. Material and methods: The research participants included 100 nurses working in hospital wards. The researcher used his own questionnaire containing questions about selected lifestyle elements. The research included also the measurement of body weight and height, and the calculation of the Body Mass Index (BMI). The results were described with the use of the basic descriptive statistics, the chi2 test, Mann-Whitney U test, and the Spearman’s rank correlation coefficient. The differences were deemed significant when p<0,05. Results: Only 5.0% of nurses devoted at least 150 minutes per week to aerobic activity. More than half of the respondents (58.0%) said that on weekdays they did not perform any strength exercises for major muscle groups. According to the nurses, lack of time (65.0%) was the greatest impediment to their physical activity. A significant percentage of the respondents (40.0%) did not pay any attention to the calorific or nutritional value of their meals. As many as 30.0% of the surveyed nurses indicated that they ate irregularly, and 22.0% of them ate only 1-3 meals during the day. Excessive body weight was observed in almost half of the participants. For the majority of the nurses, their professional work was the main source of stress (46.0%). Conclusions: Despite their knowledge on healthy lifestyle, it seems that nurses do not fully implement its objectives. Therefore, the majority of them are not good role models for patients.

The main aim of this paper was to determine whether heterozygosity (assessed using microsatellite genotypes) was correlated with the reproductive traits in sows. The study was conducted on two herds of sows of the Large White sows breed at the Limited Liability Company “Tavriys’ki svyni” (Kherson region, Ukraine) and the Agricultural Private Enterprise “Techmet-Yug” (Mykolayiv region, Ukraine). During the study, we used eleven microsatellite loci recommended by International Society for Animal Genetics (ISAG) – S0101, S0155, S0228, S0355, S0386, Sw24, Sw72, Sw240, Sw857, Sw936 and Sw951. The litter records included information on the total number of piglets born (TNB), number of piglets born alive (NBA), number of stillborn piglets (NSB), frequency of stillborn piglets (FSB), litter size at weaning (NW) in the first five parities. Individual heterozygosity estimates (for each microsatellite loci separately) and microsatellite multilocus heterozygosity (for all used loci) estimates (MLH) were used in our analysis. ANOVA was used to determine the relationship of the dependent effects (reproductive traits) to single locus heterozygosity using two classes: 0 (for homozygous individuals) and 1 (for heterozygous individuals). In addition, the following indicators were calculated for each genotype: the squared distances (d2) between alleles within an individual for each microsatellite loci and mean squared distances (mean d2) between alleles within an individual for 11 microsatellite loci. Spearman’s rank correlation coefficients were used to measure the association between d2 (for each microsatellite loci) and reproductive traits in sows. ANOVA on reproductive traits of sows belonging to different MLH and mean d2 classes was also undertaken. For sows from the Agricultural Private Enterprise “‘Techmet-Yug” were observed negative associations between heterozygosity and reproductive traits. We conclude that care should be taken when crossing between different breeders (English and Hungarian selection) to avoid outbreeding depression.

Method Approach

ABSTRACT Background Quality Indicator (QI) appraisal protocols are a novel methodology that combines multiple appraisal methods to comprehensively assess the "appropriateness" of QIs for a particular healthcare setting. However, they remain inadequately explored compared to the single appraisal method approach. This paper aimed to describe and test a QI appraisal protocol versus the single method approach, against a series of QIs potentially relevant to the South African Prehospital Emergency Care setting. Methods An appraisal protocol was developed consisting of two categorical-based appraisal methods, combined with the qualitative analysis of the discussion generated during the consensus application of each method. The output of the protocol was assessed and compared with the application and output of each method. Inter-rater reliability of each particular method was evaluated prior to group consensus rating. Variation in the number of non-valid QIs and the proportion of non-valid QIs identified between each method and the protocol were compared and assessed. Results There was mixed IRR of the individual methods. There was similarly low to moderate correlation of the results obtained between the particular methods (Spearman’s rank correlation=0.42,p&lt;0.001). From a series of 104 QIs, 11 non-valid QIs were identified that were shared between the individual methods. A further 19 non-valid QIs were identified and not shared by each method, highlighting the benefits of a multi-method approach. The outcomes were additionally evident in the group discussion analysis, which in and of itself added further input that would not have otherwise been captured by the individual methods alone. Conclusion The utilization of a multi-method appraisal protocol offers multiple benefits, when compared to the single appraisal approach, and can provide the confidence that the outcomes of the appraisal will ensure a strong foundation on which the QI framework can be successfully implemented.

Pyrin Domain

Abstract Objectives Nod-like receptor pyrin domain containing 3 (NLRP3) is one of the well characterized inflammasome that controls the maturation of pro-inflammatory cytokines and thereby the inflammation in pancreas which could be a promising target for anti-inflammatory drugs. The present study is aimed to explore whether luteolin can target the NLRP3 inflammasome and modulate its activity through the signaling protein, HSP70 in the ethanol-cerulein model of experimental pancreatitis. Methods Male albino Wistar rats were divided into four groups. Groups 1 and 2 rats received normal diet. Groups 3 and 4 rats received isocalorically adjusted diet containing ethanol for 5 weeks and cerulein (20 μg/kg body weight i.p., thrice weekly for the last 3 weeks of the experimental period). Additionally, group 2 and 4 rats received 2 mg/kg body weight of luteolin orally from third week. Results Luteolin co-administration decreased the serum levels of HSP70, oxidative stress markers, myeloperoxidase, GSH/GSSG and GST with concomitant downregulation in the mRNA expression of HSP70, caspase-1, ASC-NLRP3 and NF-κB. Spearman’s rank correlation test showed that serum HSP70 has positive correlation with the expression of ASC-NLRP3, caspase-1, NF-κB and 4-hydroxynonenal and negative correlation with GSH:GSSG ratio. Conclusions The modulating effect of luteolin on the expression of HSP70, NF-κB and thereby on ASC-NLRP3 complex may be claimed for its pancreato-protective activity.

Study Results

This study was conducted to determine the growth performance, correlation and regression estimates of seven-chicken strains in South-western Nigeria using a total of 300 day-old chicks. The birds were divided into seven groups based on their strain. The seven strains are Normal feather (NF), Fulani ecotype (FE), Frizzle feather (FF), naked neck (NN) and Transylvania indigenous strains while Hubbard and Marshal were meat-type exotic chickens. There were forty- five (45) unsexed day-old chicks in each strain except the Frizzle feather that were 30 in number. Completely randomized design (CRD) was used for the trial that lasted for 8 weeks. The birds were fed experimental diets ad libitum throughout the period of the study. Results showed that there were significant differences (p<0.05) in the initial and final weights of the birds. It was observed that exotic strains weighed heavier (3569.73gHB) than their indigenous counterparts (1391.11gNF). However, the Fulani ecotype weighed heaviest (1840.99g) among Nigeria indigenous strains during the experimental period. This showed that FE strains are generally heavy breed chicken and could be incorporated into a meat producing indigenous chicken if improved upon. The result of the correlation coefficients showed that a very strong, positive and highly significant (P<0.001) relationship existed between body weights and linear body measurements as most of the values are (>0.40). All the body parameter examined had significant (p<0.01) and direct relationship with the body weight. Shoulder-to-tail length (STL) had the highest coefficient of 0.98.The high correlation estimates obtained in this study could be as a result of pleiotropy, heterozygosity or linkage of genes in the birds. The three functions were highly significant (p<0.05) for all the parameters studied. This shows that the functions well described the parameters. On the basis of coefficient of determination (R ), the body weight of poultry birds at any age can be predicted most accurately with BRG using cubic function.

Background and Aim: The physical asymmetries associated with a prosthesis raises the question of validity of the Sensory Organization Test (SOT) measures (equilibrium score (ES) and strategy score (SS)) in lower limb amputees. This study explores the validity of these measures in transtibial amputees by correlating with their corresponding centre of pressure (COP) excursion/velocity measures. Technique: Fifteen transtibial amputees (69.5 ± 6.5 years) completed three trials for each of the six SOT conditions. Discussion: The Spearman’s rank correlation coefficients between ESs and global COP excursion/velocity measures ranged from 0.52 to 0.71 for Conditions 1, 4 and 5, 0.79 to 0.85 for Conditions 2 and 3, and 0.39 to 0.43 for Condition 6. The coefficients for SSs ranged between 0.78 and 0.97 for Conditions 1 to 5 and 0.55 to 0.67 for Condition 6. The corresponding sound and prosthetic side COP variables demonstrated varying strengths of association with ES and SS. Clinical relevance Of the two clinical measures examined, the SSs are strongly reflective of COP excursion/velocity measures and these findings have application in the interpretation of SOT when evaluating balance in transtibial amputees.

AbstractBACKGROUND:Along with time, variation in the exposome is dependent on the location and sex of study participants. One specific factor that may influence exposure co-variations is a shared household environment.OBJECTIVES:To examine the influence of shared household and partner’s sex in relation to the variation in 128 endocrine disrupting chemical (EDC) exposures among couples.METHODS:In a cohort comprising 501 couples trying for pregnancy, we measured 128 (13 chemical classes) persistent and non-persistent EDCs and estimated 1) sex-specific differences; 2) variance explained by shared household; and 3) Spearman’s rank correlation coefficients (rs) for females, males, and couples’ exposures.RESULTS:Sex was correlated with 8 EDCs including polyfluoroalkyl substances (PFASs) (p< 0.05). Shared household explained 43% and 41% of the total variance for PFASs and blood metals, respectively, but less than 20% for the remaining 11 EDC classes. Co-exposure patterns of the exposome were similar between females and males, with within-classrs higher for persistent and lower for non-persistent chemicals. Medianrss of polybrominated compounds and urine metalloids were 0.45 and 0.09, respectively, for females (0.41 and 0.08 for males), whereas lowerrss for these 2 classes were found for couples (0.21 and 0.04).CONCLUSIONS:Overall, sex did not significantly affect EDC levels in couples. Individual, rather than shared environment, could be a major factor influencing the co-variation of 128 markers of the exposome. Correlations between exposures are lower in couples than in individual partners and have important analytical and sampling implications for epidemiological study.

Abstract The supplementary old-age pension system in Poland consists of group and individual plans. This research covers the latter, namely the individual retirement accounts and individual retirement security accounts that were introduced in 2004 and 2012 respectively. The main aim of the paper is to conduct a multidimensional comparative analysis of bank retirement products including the linguistic complexity of documents creating the retirement contracts offered to individuals by banks, and the costliness and profitability of such products in the period 2012-2019. Moreover, it identifies the dependencies between the linguistic and economic traits of retirement contracts offered by banks. The correlation analysis conducted using the Spearman’s rank correlation coefficient showed that the more readable a document of a bank contract is, the higher the interest rate is and the higher the cancellation fees. The results of the study are relevant for both financial institutions and public bodies as they show the key characteristics that may influence the demand for individual retirement products in Poland and may serve as either a stimulator or a barrier in the development of supplementary old-age pension provision.

Abstract Background An exploratory field research was conducted in northwestern Ethiopia, to characterize the morphological features of Arab and Oromo goat populations as an input to design community-based breeding programs. Ten qualitative and nine quantitative traits were considered from 747 randomly selected goats. All data collected during the study period were analyzed using R statistical software. Results Plain white coat color was predominantly observed in Arab goats (33.72%) while plain brown (deep and light) coat color was the most frequent in Oromo goats (27.81%). The morphometric measurements indicated that Oromo goats have significantly higher body weight and linear body measurements than Arab goats. Positive, strong and highly significant correlations were obtained between body weight and most of the body measurements in both goat populations. The highest correlation coefficients of chest girth with body weight for Arab (r  =  0.95) and Oromo (r  =  0.92) goat populations demonstrated a strong association between these variables. Live body weight could be predicted with regression equations of y  =  − 33.65  +  0.89  ×  for Arab goats (R2  =  90) and y  =  − 37.55  +  0.94  ×  for Oromo goats (R2  =  85), where y and x are body weight and chest girth, respectively, in these goat types. Conclusions The morphological variations obtained in this study could be complemented by performance data and molecular characterization using DNA markers to guide the overall goat conservation and formulation of appropriate breeding and selection strategies.

This study into the behaviour of domestic cats (Feliscatus) aimed to assess the relationship between behavioural expressions obtained via the Qualitative Behaviour Assessment (QBA) and quantitative outcomes of temperament tests. Four behavioural tests were used: Unfamiliar person (UP); Novel object (NO); Conspecific reaction (CR); and Food offering (FO) tests. Tests were filmed and assessed using an ethogram that included 25 discrete behavioural categories, generating quantitative information (coding method) on the existing temperament dimensions. Videos were also assessed by another observer using the QBA method, based on a list of 20 adjectives rated in visual analogue scales (rating method). Data were analysed using Principal Component Analysis. Spearman's rank correlation coefficients were used to relate the principal components (PC) of QBA to the temperament dimensions obtained with the coding method. The QBA allowed us to identify three PC, explaining 76.63% of the total variance. PC1 ranged from 'calm/relaxed/friendly' to 'tense/fearful/alert', reflecting the valence of cats' behavioural and emotional expressions towards the stimuli tested. PC2 ranged from 'indifferent' to 'agitated/active', indicating the level of emotional arousal, and PC3 ranged from 'aggressive' to 'suspicious' and could be interpreted as an axis of 'aggressiveness — caution' in response to the stimuli. The first PC obtained for each test by using the coding method was significantly correlated with the PC1 of QBA, suggesting that the variations in cats' behavioural and emotional expressions identified by QBA were correlated with the main quantitative outcomes of temperament tests traditionally applied for domestic cats. QBA could be a promising tool for identifying and differentiating cat temperament profiles. Further research is required to assess the potential use of QBA as a feasible and practical method for use in shelters.
