This study was conducted to evaluate the influence and cooperation of Orthodontic patients to wear removable retainer by sending reminder text messages. 54 orthodontic patients (24 males and 30 females) aged between 18 to 25 year were enrolled for the study. Patients were randomly divided into two groups: an Experimental group (27 patients) who received timely reminder text messages and a Control group (27 patients) who did not receive any messages. Text Messages were sent thrice a week for a period of 6 months. Two measurements were calculated on plaster models i.e. Inter canine width and extraction spaces at three time intervals during the observation period. The plaster models were made at the time of insertion of retainer (T0) after 3 month of wearing the retainer (T2) and then after 6 months (T3). A statistically significant differences were observed in the intra- and intergroup comparisons. Group 1(Control) showed increase in both inter canine width and extraction spaces. Whereas Group 2 showed non-significant differences for both parameters. It was concluded from the results that reminder text messages had a positive influence on patient compliance regarding wearing the removable retainer after completion of fixed orthodontic treatment.

ABSTRACT Objectives: To evaluate the influence of text messages on cooperation of Class II patients with the use of intermaxillary elastics. Materials and Methods: The sample consisted of 42 orthodontic patients (20 males and 22 females) aged between 14 and 34 years. They were randomly divided into one of the following two groups: a control group with 21 patients who did not receive messages and an experimental group with 21 patients who received motivational and reminder text messages. Messages were sent twice a week for a period of 3 months. The patients were instructed to wear the elastics all day, removing them only during meals and replacing them daily. All patients were instructed regarding the importance of cooperation. Measurements were performed with a digital caliper on plaster models at the beginning of elastics wear (T1) and 3 months later (T2). For intragroup and intergroup comparisons between T1 and T2, paired and unpaired t-tests, respectively, were used with a significance level of 5%. Results: Statistically significant differences were observed in the intra- and intergroup comparisons between T1 and T2. Both groups showed a decrease in the sagittal distance between upper and lower arches from T1 to T2, demonstrating the effective use of elastics. However, the experimental group showed a Class II correction that was 3.7 times greater than the control group (P = .001). Conclusions: Text messages had a positive influence on the cooperation of patients regarding the use of intermaxillary elastics in the orthodontic treatment of Class II malocclusion.

This paper investigates the efficacy of articulatory training and acoustic feedback on Persian L2 learners’ production of English segmental (/ɒ/). A sample of 30 Persian ESL learners was recruited- 10 learners were randomly assigned to the experimental group 1, 10 to the experimental group 2, and 10 to the control group. Over a five-week period, the experimental group 1 received training on the manner of articulation of the segment, the experimental group 2 received acoustic-articulatory training and was exposed to CALL software for receiving feedback, and the control group was only exposed to auditory input. The groups were given a pretest, an immediate posttest, and a generalization test. The results of the study showed a significant improvement in the performance of the participants in both the posttest and the generalization test in the experimental group 2. These findings suggest the inefficiency of the mere knowledge of the manner of articulation of the segment and lend support to the feasibility of using acoustic features of sounds and computer-based, learner-centred programs for second language segmental acquisition.

Total digitalization of culture requires the extensive integration of Web 2.0 ser-vices and capabilities into music education. The penetration of digital technologies is not reduced to the technologies for fixing and distributing musical works or the means of their broadcasting but also dramatically transforms the process of creat-ing musical works. Web 2.0 offers a new distributed creativity culture and pro-vides musicians with specific opportunities to work and distribute creative prod-ucts. The study is devoted to the integration of music education and the services and opportunities that Web 2.0 provides to the mass audience (free specialized and non-specialized services), its impact on the quality of music education, as well as on the most important psychological parameters of students of music uni-versities. The study involved 150 students of R. Glier Kyiv Municipal Academy of Music (Kyiv, Ukraine); there were three groups of 50 participants: two exper-imental groups and a control one. In Experimental Group 1, training was partially integrated with Web 2.0 services; in Experimental Group 2, there was a more complete and structured integration. Based on the results of semester training and the objective test scores, a significant increase in the results of experimental groups was observed (an increase by 1.3 points in Group 1 and 2.84 points in Group 2 on a 5-point scale); Group 2 demonstrated a more significant improve-ment. The subjective assessment of the level of involvement, motivation and anx-iety showed a statistically significant decrease in academic anxiety in the experi-mental groups (2.99 and 2.01 compared to 3.98 in the control group, respective-ly) and a statistically significant increase in motivation and involvement in the group with deep integration of Web 2.0 services (Experimental Group 2). The hypothesis of the study that deep integration of Web 2.0 services and capabilities into music education will increase objective academic results, motivation and stu-dent involvement has been fully confirmed. It has also been revealed that it helps students reduce academic anxiety. The research results can be used as a basis for further research and in the course of the development of music education curricu-la based on online learning, mobile learning and the integration of music learning into a digital environment.

Abstract BackgroundThe incidence of thyroid nodules increased significantly, but the mortality rate of thyroid cancer remained stable or even decreased. However, surgical treatment of thyroid nodules is more aggressive, including the number and scope of surgery. the purpose of our study was to evaluate whether unilateral thyroid nodules affect the malignancy risk of contralateral thyroid nodules. Methods We conducted a retrospective study on all patients with thyroid nodules in a tertiary hospital within one year. Unilateral and bilateral thyroid nodules were the control group and the experimental group, respectively. Based on the TI-RADS grades, the experimental group and the control group were divided into two subgroups. We used chi-square test or Fisher's exact test to evaluate whether there were statistical differences in the incidence and pathological types of thyroid cancer between the experimental group and the control group. Results Our study showed that there was no significant difference in malignant risk between the experimental group 1 and the control group 1, and the experimental group 2 and the control group 2 (20%vs35%, p=0.724, 63.16%vs76.32%, p=0.297, respectively). Both the a-side thyroid of the experimental group and the control group were papillary thyroid carcinoma, including micropapillary thyroid carcinoma, and there was no difference in the proportion of micropapillary thyroid carcinoma (p = 0.200, 0.620, respectively). Conclusions There is no evidence that bilateral thyroid nodules affect each other in terms of malignant risk, that is, in bilateral thyroid nodules, unilateral thyroid cancer does not change the malignant risk of contralateral thyroid nodules.This study has been registered with the Chinese Clinical Trial Registry, clinical trial registration number: ChiCTR2000038611, registration time: 2020-09-26.

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.

Background Virtual simulation is the re-creation of reality depicted on a computer screen. It offers the possibility to exercise motor and psychomotor skills. In biomedical and medical education, there is an attempt to find new ways to support students’ learning in neurophysiology. Traditionally, recording electroencephalography (EEG) has been learned through practical hands-on exercises. To date, virtual simulations of EEG measurements have not been used. Objective This study aimed to examine the development of students’ theoretical knowledge and practical skills in the EEG measurement when using a virtual EEG simulator in biomedical laboratory science in the context of a neurophysiology course. Methods A computer-based EEG simulator was created. The simulator allowed virtual electrode placement and EEG graph interpretation. The usefulness of the simulator for learning EEG measurement was tested with 35 participants randomly divided into three equal groups. Group 1 (experimental group 1) used the simulator with fuzzy feedback, group 2 (experimental group 2) used the simulator with exact feedback, and group 3 (control group) did not use a simulator. The study comprised pre- and posttests on theoretical knowledge and practical hands-on evaluation of EEG electrode placement. Results The Wilcoxon signed-rank test indicated that the two groups that utilized a computer-based electrode placement simulator showed significant improvement in both theoretical knowledge (Z=1.79, P=.074) and observed practical skills compared with the group that studied without a simulator. Conclusions Learning electrode placement using a simulator enhances students’ ability to place electrodes and, in combination with practical hands-on training, increases their understanding of EEG measurement.

Introduction: Prevention of dental caries and non-carious lesions associated withdemineralizing effect of estrogen imbalance in perimenopause women isrelevant problem in modern dentistry.The aim: To improve the effectiveness of prevention of caries and non-cariouslesions in female patients with estrogen imbalance.Materials and methods: 3 groups of patients were selected for the study (20women in each): the patients of the control group receiving no additionaltreatment, the patients of experimental group 1 receiving general therapy withcomplex calcium supplements, the patients of experimental group 2 receivinggeneral therapy of complex calcium medicines combined withaminobisphosphonates.To quantify bone density of the jaws by computed tomography method, X-rayattenuation scale, called the Hounsfield scale was used. Bone tissues of the jawswere studied using 3D cone beam computed tomography scanner PlanmecaProMax. Planmeca Romexis® software was used for data processing andinterpretation. Estrogen level was estimated in all patients to confirm itsimbalance. The level of serum acid phosphatase was determined for indirectstudy of osteoporosis degree.Results: At the beginning of the research, significant bone demineralization andincreased level of acidic phosphatase were observed in all groups of women. In6 months of treatment the Hounsfield index and the level of acidic phosphatasein the control group were almost unchanged; in experimental group 1 – 1571±44 HU and 4.93 ± 0.26 IU/l; in experimental group 2 – 1701±48 HU and 2.43± 0.18 IU/l.Conclusions: Combination therapy consisting of calcium phosphate withvitamin D3 and aminobisphosphonates used for 6 months increased bonemineralization by 13.05% and reduced the activity of acid phosphatase by64.2%. This therapeutic complex results in decreased destruction of bone tissueand enhances remineralization of bone tissue and dental hard tissues.Key words: teeth mineralization, osteoporosis, estrogen dysfunction, Hounsfieldindex.

Abstract Background Acute uncomplicated lower urinary tract infection (UTI) is one of the most common bacterial infections. Patients usually present with dysuria, urinary urgency, urinary frequency and suprapubic pain or tenderness. Approximately 150 million people are diagnosed with UTI each year worldwide. The high recurrence rate of lower UTI is a common problem of clinical treatment. The misuse of antibiotics has led to the emergence of a number of resistant bacterial strains. Thus, traditional Chinese medicine is considered as an alternative option for treating acute uncomplicated lower UTI. Thus, this study aims to evaluate the efficacy, safety and recurrence rate of Sanjin tablets (SJT) for the treatment of acute uncomplicated lower UTI; explore whether SJT can reduce or substitute the use of antibiotics in the treatment of acute uncomplicated lower UTI. Methods/Design In this study, a randomized, double blind, double dummy, parallel control of positive drug, multicentre clinical study will be established. A total of 252 patients with acute uncomplicated lower UTI (syndrome of dampness-heat in the lower jiao) will be randomly allocated in the ratio of 1:1:1 to three groups: experimental group, control group 1 and control group 2. The experimental group receives Sanjin tablets plus levofloxacin tablets (LT) placebo; the control group 1 receives LT plus SJT placebo; and the control group 2 receives SJT plus LT on the first 5 days, SJT plus LT placebo on the last 2 days. Each group will be treated for 7 days and followed-up for 1-2 times. The primary outcome measures of effective rate and recurrence rate are symptoms. Secondary outcome measures of effective rate and recurrence rate are the urine leukocyte, bacteriology examination and safety assessment. Outcomes will be assessed at baseline and after treatment. Discussion This study protocol will provide the research data of efficacy, safety and recurrence rate of SJT for the treatment of acute uncomplicated lower UTI; explore the possibility of using SJT to reduce or substitute the use of antibiotics. The results of this study will improve the rational use of drugs, especially the rational application of antibiotics. It will also enable safety evaluation from laboratory indices and adverse events, which will provide reliable evidence for clinical treatment.
