The aim of the study was to conduct a comparative assessment of the optical density of bone tissue of the alveolar process of the jaws of rats in supraocclusive relationships of individual teeth in the age aspect. Materials and methods: The study was performed on 60 white laboratory rats. Rats were divided into control (30 individuals) and experimental (30 individuals) groups. According to the age of rats each group was divided into 3 subgroups (10 animals): young, mature and senile. In the experimental group, the state of supraocclusion was modeled by increasing the height of the lower right second molars placing a seal 1 mm high. Experimental animals were removed from the experiment on the 15th day through decapitation. The lower jaws were skeletonized, jaw blocks were sawn in the molar area. Bone mineral density was determined using optical densitometry. The statistical processing defined the average (M) and its error (m). The statistical significance of the difference in two independent groups was performed according to nonparametric criteria (Mann-Whitney U-test and W-Wilcoxon test). Statistical processing was conducted with the help of integrated package of statistical program AtteStat 12.0.5 for MS Excel. Differences at p≤ 0.05 were considered statistically significant. Results: Statistical discrepancy is present in rats of mature and senile age, as well as between the indicators of all rats of the control and experimental groups (≤0.05). No significant difference was observed in young rats, but the indicators of the experimental group were 3.82% worse than in the control group. In senile rats, the density of the alveolar process decreased by 26.6%, in adult rats by 17.5%. Conclusions: The presence of supraocclusive relationships of individual teeth causes a decrease in bone density of the alveolar process of the jaws in rats. The greatest loss of density among age groups in elderly rats.

The purpose of this study is to determine the effect of the "patience training program" on the patience and life satisfaction levels of university students. The study was organized as a pre-test, post-test experiment and control group design. For a total of 30 students from which were 17 in the control group and 17 in the experimental group, patience training was given for 5 weeks. The "Patient Scale" developed by Schnitker (2010) and adapted to Turkish by Eliüşük and Arslan (2016) and the "Life Satisfaction Scale" developed by Diener, Emmons, Larsen and Griffin (1985) and adapted to Turkish by Dağlı and Baysal (2016) were used as a data collection tool in the study. The "Wilcoxon" test was used for the comparison of in-group differences in the analysis of obtained data and the "Mann-Whitney U" test was used in examining the differences between the two groups. As a result of the study, it was observed that the patience and life satisfaction average scores of students in the experimental group receiving "patience training" increased significantly, while there was no significant difference in the patience and life satisfaction averages scores of the control group students.

One of the factors that influence Kadarzi's achievement is the knowledge and attitudes of the toddler's mother. This study aims to determine the effect of counseling using backsheet media on the knowledge and attitudes of toddlers' mothers about Kadarzi in the Cipeundeuy Health Center District of West Bandung Regency. The research design used was quasi-experimental with a pre-post test control group design model with a total sample of 28 people each for the experimental group and the control group. The experimental group was given an intervention in the form of counseling using flipchart media, while the control group was given an intervention in the form of counseling using leaflet media. The results obtained from the Wilcoxon test in the experimental group and the t-dependent test in the control group were changes in the increase in knowledge and attitude scores in the experimental group and the control group after intervention (p <0.005). The results of the Mann-Whitney test showed no significant difference between knowledge and attitude scores in the experimental group and the control group (p> 0.005). It is better to do further research related to Kadarzi's behavior so that the application of the Kadarzi indicator can be monitored so that it can describe the results of attitudinal changes, and to increase Kadarzi's knowledge and attitudes to toddler mothers.

Background. Thin soles and resulting lameness in cows are often due to abrasive walking surfaces that cause increased wear. The aim of this project was to compare horn growth and wear and sole thickness in cows kept on rubber mats versus concrete in a free-stall barn. Methods. To examine horn growth and wear and sole thickness, we examined two groups (Group 1 kept on concrete [control] and Group 2 on rubber mats) of 12 cows each at 2-week intervals over a 12-week period. The 12 cows in each group were selected to achieve equal parity in each group, as follows: four cows, parity 1; four cows, parity 2; two cows, parity 3; and two cows, parity 4. The four cows from the parity 1 group had the most days in milk in the herd irrespective of milk production. The remaining eight cows had the fewest days in milk (most recently calved) irrespective of milk production. Results. Cows in the control group had a significant increase in claw horn growth over the study period, compared to the control group. Most of this difference in horn growth occurred during the first 2 weeks of the study. There was no significant difference in claw horn wear and sole thickness at 2 weeks or at the end of the study. There was, however, a non-significant difference in wear between cows in the 2 groups at the end of the study, with cows in the control group showing most wear. Cows in the experimental group exhibited significant increases in all parameters (claw length, wear, and growth; sole thickness) when measured at the beginning and end of the trial, whereas cows in the control group showed a significant increase in claw length and sole thickness.Discussion. These findings suggest that there was a compensatory increase in horn production in response to accelerated claw horn wear in the control group. Statistical significance in wear might have been attained between groups at the end of the study if the study had continued over a longer period.

Postural Disorders

Introduction. Vibration disease (VD) is one of the leading occupational diseases. One of the manifestations of this disease when exposed to general vibration may be a violation of balance.The aim of the study is to identify the imbalance and the causes of their occurrence in patients with vibration disease.Materials and methods. 3 groups of patients were examined. The first group consisted of 50 patients diagnosed with VD associated with combined exposure to local and general vibration (age 48.7±3.1 years); the second group consisted of 50 patients diagnosed with VD associated with exposure to local vibration (age 48.9+2.8 years); the control group consisted of 50 relatively healthy men not in contact with vibration (age 49.1+2.5 years). Survey on electronic stabilometer ST–150 (Biomera, Russia). Patients performed the Romberg test standing barefoot vertically on a stabilometric platform with a “European” stop position. Statistical processing of the results was carried out using the software package “Statistica 10.0” (StatSof, USA, 2011). Methods of descriptive statistics included estimation of median, lower and upper quartiles. The statistical significance of the differences was determined using the nonparametric Wilkinson method. Differences were considered statistically significant at p<0.05.Results. In the analysis of the obtained stabilometric parameters found that in the first group of patients marked imbalance.Moreover, in comparison with the second group and the control group in the phase with eyes closed, patients are more difficult to maintain a given posture, which increases the length of statokinesigram (p=0.02 and p=0.005), increasing the speed of movement of the center of pressure (p=0.03 and p=0.004) and the square of the deviation of the center of pressure (p=0.03 and p=0.004). When closing the eyes, patients put more effort to maintain balance, which affects the rate of mechanical work (p=0.001 and p=0.001). When comparing the second group with the control group, no statistically significant difference was found in the main stabilometric indicators.Conclusions: In the group of patients with VD associated with the combined effects of local and general vibration, marked (64%) and moderate (36%) postural disorders, especially in the phase of closed eyes. In the group of patients with VS associated with local vibration exposure and in the control group, imbalance was detected in 10% and 6%, respectively. The leading role in the occurrence of postural disorders in patients with VD, associated with the combined effects of local and general vibration, plays the formation of a focus of stagnant excitation in the centers of vibration sensitivity. In the future, the pulse can spread to nearby centers of pain, temperature sensitivity and proprioception, which contributes to the emergence of lower limb polyneuropathy and impaired stability in patients with vibration disease.

This study examined the effect of administering an additional dose of prostaglandin F2 alpha (PGF2?), in a fixed-time artificial insemination protocol (FTAI), on the fertility of female Nellore cattle. Two experiments were carried out: the first (Experiment I) took place in the state of Tocantins and the second (Experiment II) in the state of Pará, Brazil. In Experiment I (E1), 80 cows were used in three treatments (T1, T2 and T3) in which all received the same FTAI protocol. In T1 (n = 29), the cows received 12.5 mg of Dinoprost on day 9; in T2 (n = 28), they received the additional dose on day 10; and in T3 (n = 23; control group), the animals did not receive the additional PGF2? dose. Experiment II consisted of 147 bovine females distributed into two treatment groups, namely, T1 - 72 animals receiving the same protocol as T1 of E1; and T2 - 75 animals receiving the same protocol as T3 of E1. Statistical analysis was performed using SAS software, applying the PROC NPARWAY procedure for E1, and means were compared by the Wilcoxon test at the 5% significance level. In Experiment II, the data were subjected to analysis of variance by PROC GLIMMIX and means were compared by the T test at the 5% significance level. The following pregnancy rates were obtained in Experiment I: T1 - 62.06% (18/29); T2 - 57.14% (16/28); and T3 - 52.17% (12/23), with no significant difference observed between treatments. In Experiment II, pregnancy rate in T1 was 66.67% (48/72), whereas in T2 it was 41.33% (31/75), with a significant difference detected (P < 0.05). An additional dose of PGF2? provides an increase in pregnancy rate in Nellore females.

This study aims to determine whether group guidance services can improve the assertiveness of class IX students of SMPN 1 Sakra. The sampling technique used in this study was random sampling, by randomly taking 20 students. Methods of collecting data using a psychological scale. Validity test: Product Moment correlation formula and reliability: Alpha formula. Sample homogeneity: Chi quadratic formula. Data analysis: Wilcoxon test. Based on the results of the pre test average student assertiveness in the experimental group 57% (low) and the control group 61% (moderate). Whereas in the post test results in the experimental group after being given group guidance services, the average student assertiveness became 75% (high) and the post test results of the average assertiveness of the control group students who were not given group guidance services became 62% (moderate). Wilcoxon test results obtained Thitung = 6 and Ttabel = 8. If Thitung <Ttabel then Ho is rejected and Ha is accepted. Because Thitung <Ttabel then there is a significant difference between the value of the post test of the two sample groups, it means that group guidance services can improve student assertiveness.

Candida albicans(C. albicans) is one of the bacteria that resides in the oral cavity, and the ones living in medical and commercial denture resins, commonly cause diseases. Therefore, this study was conducted to confirm the antibacterial activity of C. albicans using a denture base resin containing peony extract with antibacterial properties. For the antibacterial effect, optical density and confocal laser microscopy were used. Contact angle measurements and color change measurements were performed to confirm the physical change of the material added with the antibacterial agent to the denture reline resin. As a result of the antibacterial test, the experimental group exhibited antibacterial activity against C. albicans. Compared to the optical density results, the results of the experimental group showed a significant difference. As a result of Fluorescent images showing (confocal laser microscope), the control group showed a lot of live bacteria, no bacteria appeared in the experimental group. All group did not show any physical changes. As a result of the contact angle measurement, the surface of the experimental group was changed to hydrophilic. In addition, there was no change in the color of the denture reline resin containing peony extract. In conclusion, it was confirmed that the peony extract contained antibacterial activity of the denture resin, and further studies should be conducted on various bacteria for denture base resin disinfection.
