ABSTRACT Objective The objective of the present study was to investigate the relationship between dental caries and fluoride concentration in unstimulated whole saliva of non-fluoride users. Study design Ninety subjects, aged 7 to 15 years who were non-fluoride users, participated in the study. Dental caries was recorded using modified Moller's index. Unstimulated whole saliva samples were collected early in the morning. Fluoride concentration in saliva was estimated using combination ion specific fluoride electrode (Orion). Water fluoride of the area ranged from 0.34 to 0.38 ppm. Results Salivary fluoride concentration (mean ± SE) in saliva (n = 90) was 0.03 ± 0.03 ppm with a range of 0.01 to 0.24 ppm. The DMFT ± SE was 3.26 ± 0.27 and DMFS 4.30 ± 0.42. Correlation of fluoride concentration in saliva was inverse and significant with DMFT (p < 0.01) and DMFS (p < 0.01) using the Spearman's rank correlation coefficient. Conclusion Fluoride concentration in saliva could be an indication of the individual's caries risk and help isolating high risk individuals requiring special chairside preventive strategies.

Objective: Several studies have reported that low levels of vitamin D (25(OH)D) are associated with an increased risk of dental caries and that optimal levels may offer protection This study aimed to assess the relationship between serum and saliva 25(OH)D levels and caries among young children. Study design: A total of 120 healthy children were recruited; 93 with caries and 27 caries-free. Dental caries status was evaluated using decayed, missing and filled in primary teeth (dmft) index. Blood and unstimulated whole saliva samples were collected. Laboratory analysis was performed using Enzyme-Linked Immunosorbent Assay Kit. Data were analyzed with descriptive statistics, bivariate and Spearman’s rank correlation analysis. Results: There were no significant associations between serum and saliva 25(OH)D levels and caries status (P &gt; 0.05). Levels of 25(OH)D in serum were significantly higher than levels found in saliva (P &lt; 0.05), and a correlation between serum and saliva 25(OH)D levels was observed (P &lt; 0.05). Conclusions: The association between serum and saliva 25(OH)D and dental caries in young children was inconclusive. However, a positive and significant correlation was observed between serum and saliva 25(OH)D levels. Further studies are warranted to investigate the definite relation between 25(OH)D levels and dental caries and using saliva 25(OH)D as a non-invasive alternative method over blood samples.

Purpose: to determine the relationship between the performance of basic elements and indicators of static and dynamic balance in the training process of young acrobats 6-7 years. Material and methods. The study involved 16 young acrobats at the stage of initial training (age 6-7 years). All parents of the participants gave written consent for the participation of children in the study. The study involved testing the technique of performing basic elements of sports acrobatics and assessing the static and dynamic balance of young athletes. The relationship between (swallow, shoulder blade, forward squat, wheel (sideways overturning), bridges) and static and dynamic equilibrium tests was determined. Spearman's rank correlation coefficient method was used as a method of statistical analysis. Results. It is established that the largest relationship between the performance of basic elements and static balance in the basic exercises of young acrobats have: Romberg's test with the elements "Swallow", "Stand on the shoulders", "Bridge"; Biryuk test with elements "Swallow", "Wheel", "Bridge"; balance "Swallow" with elements "Swallow", "Wheel"; static equilibrium test with the elements "Swallow", "Rack on the shoulders", "Rolling forward with a squat", "Wheel". Reliable values ​​of the correlation coefficient were established between the tests of dynamic balance and the basic elements of sports acrobatics in young athletes 6-7 years, namely: "Swallow", "Flip forward with a squat", "Wheel" and "Bridge". The analysis of special tests of static and dynamic balance in mastering the basic elements of acrobatics at the first stage of long-term training makes it possible to use them to determine the level of coordination capabilities of young athletes and further improve the use of acrobatic exercises. Conclusions. A reliable relationship between the performance of basic exercises and indicators of static and dynamic balance in young acrobats at the initial stage of training. It is shown that the level of static and dynamic balance is of great importance for the assimilation and improvement of basic elements of technology by young acrobats 6-7 years. Static and dynamic balance tests can be used to individually build training programs and young acrobats. It is shown that sports acrobatics is a significant means of developing the balance of children 6-7 years.

Objective To compare dental arch dimensions of children in the primary dentition with repaired unilateral clefts of the lip and palate (UCLP) to a noncleft group of a similar age and determine how the dimensions of the cleft arches relate to an index of treatment outcome. Method Dental study casts of 44 5- to 6-year-olds with complete UCLP (22 boys and 22 girls) from a single center, whose primary surgery had been carried out by one surgeon, were matched for age, sex, and ethnicity with dental study casts from a longitudinal growth study. Analysis of variance was used to ascertain differences in arch dimensions between the two groups. The cleft group casts were then assessed with an established index of surgical outcome, the 5-year-old index. Spearman's rank correlation coefficient was used to see how the arch dimensions of the cleft group related to the categories of the index. Results and Conclusions Maxillary arch dimensions were significantly smaller in the cleft group than in the noncleft group, irrespective of sex (p < .05). In the mandibular arch, there was no difference between the cleft and noncleft groups (p > .05). Maxillary arch dimensions of the cleft group correlated significantly with the 5-year-old index for arch length and intercanine width (p < .05) but not intermolar width (p = .842). This would suggest that the 5-year-old index is a suitable tool for assessing the outcome of treatment in the primary dentition for anteroposterior and anterior transverse arch dimensions.

Purpose The first purpose of the present study is to investigate the coverage of journal articles in Physics in various sources of altmetrics. Secondly, the study investigates the relationship between altmetrics and citations. Finally, the study also investigates whether the relationship between citations and altmetrics was stronger or weaker for those articles that had been mentioned at least once in the sources of altmetrics. Design/methodology/approach The journal articles in Physics having at least one author from an Indian Institution and published during 2014–2018 in sources of altmetrics have been investigated. Altmetric.com was used for collecting altmetrics data. Spearman’s rank correlation coefficient (ρ) has been used as the data found to be skewed. Findings The highest coverage was found on Twitter (22.68%), followed by Facebook (3.62%) and blogs (2.18%). The coverage in the rest of the sources was less than 1%. The average Twitter mentions for journal articles tweeted at least once was found to be 4 (3.99) and for Facebook mentions, it was found to be 1.48. Correlations between Twitter mentions–citations and Facebook mentions–citation were found to be statistically significant but low to weak positive. Research limitations/implications The study concludes that due to the low coverage of journal articles, altmetrics should be used cautiously for research evaluation keeping in mind the disciplinary differences. The study also suggests that altmetrics can function as complementary to citation-based metrics. Originality/value The study is one of the first large scale altmetrics studies dealing with research in Physics. Also, Indian research has not been attended to in the altmetrics literature and the present study shall fill that void.

The Relationship

AbstractThe relationship between puberty and the cessation of luteal activity after nutritional restriction was evaluated in 15 Angus × Hereford heifers. Heifers attained puberty at a body weight of 297 (s.e. 6) kg and a body condition score (BCS) of 5·5 (s.e. 0·1) on a scale of 1 (emaciated) to 9 (obese). After 154 (s.e. 16) days of nutritional restriction, heifers became anoestrus at a weight of 273 (s.e. 8) kg and a BCS of 3·0 (s.e. 0·2). The Spearman's rank correlation coefficient between date of-puberty and date of cessation of luteal activity was (r = –0·49; P < 0·06). This indicates that the heifers that attained puberty first were the last to cease luteal activity during nutritional restriction.

The purpose of the article was a theoretical analysis and experimental research of the problem of the relationship between the level of behavioural self-regulation and the ability to overcome psychological barriers among students. In the theoretical part of study was considered works such scientists as V. Morosanova, N. Podymov, R. Shakurov et al. Authors concluded previous studies have indicated influence of the level of self-regulation on an ability to overcome psychological barriers. The study involved 75 people and was carried out in two stages. The experimental research allows authors to make a conclusion about the influence of the level of behavioural self-regulation and its components, on the ability of students to overcome psychological barriers. This influence consists in the fact that low level of self-regulation of students' behavior and its components inhibits overcoming of psychological barriers among students. The analysis of correlations between the availability of psychological barriers and the features of self-regulation was carried out by means of Spearman's rank correlation coefficient. Statistical analysis showed significant correlations between some components of self-regulation as planning, modeling, programming, appraisal of results, the general level of self-regulation and the ability to overcome psychological barriers among students. The results can be applied when developing the system of psychological assistance to students in the formation of the ability to overcome psychological barriers by increasing the skills of behavioural self-regulation. The research data can be introduced into the work of a practical psychologist in education, for drafting of psychocorrection programs aimed at developing students' ability to overcome psychological barriers.

Physical activity performed at recommended levels is associated with multiple health benefits. The aim of the study is to describe the relationship between socioeconomic characteristics (SES) of the environment and the volume of physical activity performed by youths. The research group consisted of 159 participants (100 women, 59 men) aged 15, living in the Prešov region. Physical activity levels were assessed using the international physical activity questionnaire IPAQ (long version). The SES of districts in the Prešov region was assessed based on the data available in databases of the Statistical Office of the Slovak Republic. The presented study was supported by VEGA 1/0840/17 project. The relationship between socioeconomic characteristics of the environment and volume of physical activity was examined using the Spearman’s rank correlation coefficient. The results did not reveal any significant relationships between SES and the volume of physical activity practiced by the monitored group of population.

The Relationship

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.

Introduction. One of the most significant components of acute destructive pancreatitis (ADP) is enzymatic parapancreatitis (EP). The severity of the defeat of the retroperitoneal tissue from the early stages of the disease largely determines its course.The objectivewas to assess the features of the evolution of the pathological process in the retroperitoneal tissue in ADP and the effect of EP on the course of phase I of ADP.Methods and materials. 63 cases (ADP) without enzymatic peritonitis were analyzed. The average age of patients was (46.6±3.2) years (p≤0.05). The sum of points according to the express diagnostic scale of the SPb I. I. Dzhanelidze RIEM was (3.7±0.2) points (p≤0.05). The average time from the onset of the disease to the start of therapy was 2 days (from 7 to 1 day).Results. Types of EP at admission were distributed as follows: type B – 17.5 % (n=11) of cases, type C – 44.4 % (n=28) of cases, type D – 30.2 % (n=19) of cases, type E – 7.9 % (n=5) of cases. Spearman’s rank correlation coefficient for assessing the relationship between the severity of the condition and the type of parapancreatitis was 0.069. Infiltrative parapancreatitis (IP) was formed in 93.4 % of cases. The types of infiltrative parapancreatitis (pancreatic infiltrate) were distributed as follows: type A – 12.3 % (n=7) of cases, type B – 21.1 % (n=12) of cases, type C – 36.8 % (n=21) of cases, type D – 19.3 % (n=11) of cases, type E – 10.5 % (n=6) of cases. There was a pronounced relation between the severity of the patient’s condition and the prevalence of IP, the Spearman’s rank correlation coefficient was 0.82.Conclusions. EP is formed in most cases of acute destructive pancreatitis and is evolutionary. It has a significant effect on the severity of the patient’s condition and the course of acute destructive pancreatitis in the infiltrative phase of the disease.
