Twenty-eight male and female Central Pennsylvania third-graders participated in a study of the effects of induced self-concept. Group I Ss ( N = 14) were administered Items 1 to 40 of the Piers-Harris Children's Self-concept Scale followed by a mathematics test. The children were then administered Items 41 to 80 of the self-concept scale after being told that they had made high scores on the mathematics test. Group II Ss (N = 14) were administered the same tests but were told that their performance on the mathematics test was not adequate. The results showed that Group I Ss' scores on the self-concept scale did not change while Group II Ss' scores decreased. Discrepancies in the children's expected and reported performances on the mathematics test may have affected their subsequent self-concept ratings.

High (Ha) and low (La) scorers on the MAS were instructed to alphabetize a deck of 30 words, 10 each of which were high, medium, or low vivid. Group I had 3 trials with incidental instructions (told only to sort), a recognition test of the words, three more trials with instructions to learn the words, and a second recognition test. Group II had 6 incidental sorting trials followed by a recognition test. It was hypothesized that Ha Ss would sort more efficiently and recognize fewer words because of a greater tendency to focus on fewer available cues. Findings in support of the hypothesis were that Ha Ss sorted more rapidly and more accurately, recognized fewer words, and showed greater disruption in the sorting task when instructed to learn the words. In addition, Ha Ss evidenced a “sensitized” reaction to medium vivid words.

Physical Activity Effects in Elderly Female: Evaluation through Six-minute Walking Test Study aim. Aerobic capacity is very important for elderly. Daily living activities, such as walking, doing housework and shopping, require a good strength, but also a good aerobic endurance. The aim of this study was to verify the effects of regular training activity on a typical daily action, such as deambulation. Material and methods. Twenty-six volunteer elderly women randomly divided into two groups, group II (age = 64,5 ± 3,58 years, weight = 61,67 ± 4,25 kg, height = 1,62 ± 0,04 m; BMI = 23,67 ± 1,79 kg m-2), group I (age = 65,21 ± 4,59 years, weight = 63,36 ± 7,59 kg, height = 1,62 ± 0,06 m; BMI = 24,1 ± 1,98 kg m-2) participated in this study. Groups performed endurance training for eight weeks (2 days per week, 1 hour each, for experimental group II; 1 day per week, 1 hour each, for experimental group I). Exercises involved in many possibilities of physical expression to keeping all body in motion for at least 30 min. During the second 30 min exercises for abdominal and lower limb muscles were proposed. The physical efficacy was tested through 6 min walking test. Results. After the training all people increased the distance in the test. Group II participants significantly improved their distance (pre-training = 636.25 m, post-training = 673.75 m). Group I reported also improvements (pre = 568.21 m; post = 600 m), but with a minor level of significance. Conclusions. Specific regular physical activity provides significant benefits adopting two sessions per week but it is also important do not underestimate the possibility, where people can not, of a one training session per week. Regular and adequate levels of physical activity allow improving daily living activity helping the elderly to keep their autonomy as long as possible.

ABSTRACT Aim The present study was primarily designed to evaluate the outcome of guided bone graft regeneration in peri-implant defects by combining recombinant human platelet-derived growth factor-BB (rhPDGF-BB) and granules of beta-tricalcium phosphate (B-TCP) mounted by resorbable biomesh membrane. Secondary objective was to determine the value of resorbable barrier membrane to improve the efficacy of the growth factormediated regeneration. Materials and methods A randomized controlled study comprised 14 participants (8 males and 6 females, mean age 37 years, range 19—55 years), in which a total of 15 implants (10 in maxilla and 5 in the mandible) were placed. Fifteen implant sites were randomly divided by picking a code into three groups: Test group I (n = 5) ß-TCP + rhPDGF (0.3 mg/mL) + biomesh, test group II (n = 5) ß-TCP + rhPDGF, and control (n = 5) ß-TCP + biomesh. The experimental site was examined clinically for the gingival status and radiographically for the bone status. Results Statistically significant difference in preoperative and postoperative measurements was observed for test groups I and II in all the parameters except width; in contrast, there was no significant difference observed for the control group from baseline to 5 months postoperatively. On intergroup comparison, statistically significant difference was observed between test group I vs control group and test group II vs control group, but it was not significant between test groups I and II, which was further confirmed using global performance scale score. Conclusion It concluded that rhPDGF-BB and ß-TCP mounted by resorbable biomesh membrane played a synergistic role in the management of peri-implant defects. Clinical significance Bone regenerated using ß-TCP with rhPDGF-BB in the reversal of peri-implant defects. How to cite this article Arora R, Verma UP, Dixit J, Lal N.

Background of the Study: Lead effects were assessed by analyzing the impacts of the extract on the liver enzyme concentrations and hematology parameters. Materials and Methods: Thirty five male wistar rats weighing 85-110 g were distributed into five groups consisting of seven rats each. Group I served as control group, group II served as the test group, groups III, IV and V served as treatment groups. Lead acetate solution was given to the rats orally at a dose of 50 mg/kg body weight and 200 mg/kg of fruit extracts for 14 days. On day 15, biochemical analysis were carried out. Results: Effects of extracts showed that ALT,AST and ALP concentration in group II was observed to be significantly (p<0.05) higher than the control and treatment groups with values. The hematology results showed that lead did not cause a significant reduction in the packed cell volume, white blood cell and red blood cell counts. However, the group treated with carrot and garden egg showed slight increase in RBC and WBC count when compared with the positive and negative control groups. Conclusion: From the results above, it showed that the fruits extract have hematopoietic potentials and hence aid in the hepatoprotection of the liver of lead induced Wistar rats.

IIrrigation solutions used and time of use has a definite effect on the micro hardness & other physical properties of dentin which in turn have direct consequence on the longevity functional performance of root canal treated teeth. To evaluate the effect of different irrigation solutions on micro hardness of root dentin.Forty extracted single rooted lower premolars were used. After instrumentation all the root halves were randomly assigned into 4groups (n=10) and brought in contact with one of the following irrigants for 5 minutes. Group I: 10 ml of 5% Sodium Hypochlorite (NaOCl).Group II: 10 ml of 17% ethylene diamine tetra-acetic acid (EDTA) followed by 10 ml of 5% NaOCl.Group III: 10 ml of 5% NaOCl followed by 10 ml of 2% chlorhexidine digluconate (CHX).Group IV: 10 ml of 5% NaOCL followed by flush of 10 ml distilled water then by 10ml of 2% CHX. Dentin micro hardness was measured at baseline and after treatment to determine the change in micro hardness, using Vickers tester.Data was analyzed using following parametric tests t-test, ANOVA test and Post Hoc test. Group II ie final irrigation with EDTA showed the highest percentage decrease in micro hardness values, followed by group III, then group IV and the lowest was group I. All groups showed a significant difference between each other (P &#60; 0.05), except group III and IV. The coronal third showed the highest percentage decrease with significant difference between apical and middle thirds (P &#60; 0.05).EDTA with NaOCl causes greatest changes in dentine micro hardness, an intermediate flush with normal saline should be given for prevention of precipitation with NaOCl & CHX.

Corn silk (Stigma maydis) contains compounds that play a role in wound healing, such as flavonoids, saponins, tannins. This study aims to formulate a gel from corn hair extract and see its activity in healing burns. The test group was divided into four groups: group I (hot metal induction), group II (without extract ), group III (corn hair extract concentration 5%), and group IV (comparison B®), which metal induction. The parameters observed were % wound healing, epithelialization time, and histopathology. The results of the study on the average% of burns healing rate 7, 14 and 21 days, namely group I (27,92%; 62,42%; 100%), group II (35,39%; 60,16%; 100%), group III (44,05%; 63,69%; 100%) and group IV (32,81%; 66,48%; 100%). The mean time of tissue peeling epithelialization groups I, II, and III was on day 16, and group IV was on day 17. For the histopathological results, the mean score of collagen fibers, fibroblast cells, and epithelialization was respectively group I (2,2; 2,7; 2), group II (2,8; 2,9; 2), group III (3,3; 2,9; 2,7), and Group IV (3,9; 3; 3). The results of the two-way ANOVA statistical test on % burn healing (p> 0.05) and one-way ANOVA at the time of epithelialization (p> 0.05) and the histopathological score (p <0.05) showed that group III (the corn hair extract 5 %) could influence the process of healing burns.

Sperm motility decreasing in a semen sample over time is an indirect approach to assess spermatozoa viability and should be related to the ejaculate fertility. The biospeckle (BSL) is an interacting phenomenon between laser light and biological specimens that allows measurement of sperm kinetic activity by means of an index called the inertial moment (IM). The aim of this work was to evaluate sperm motility diminishing in frozen bovine semen with BSL and analyze semen fertility in relation to the motility decreasing behavior patterns showed by different semen samples. Fertility was assessed by beef heifer conception rates after AI. Semen of 6 mature IA donor bulls (Bos taurus indicus) was previously divided in 2 groups (group I: motility ≥50%; group II: motility <50%), each group comprised 3 animals. Semen was thawed at 37°C for 30 sin a water bath. One aliquot of 10 μL was placed in a warmed slide, covered with a slip, and evaluated by light microscopy and BSL just after thawing. Then, samples were kept at room temperature to induce a decrease in sperm motility. Each sample was illuminated 6 times by laser light at intervals of 2 min (n = 36) and IM values were obtained. The semen samples were used in an AI program of beef heifers (n = 166) under the same nutrition and management conditions. All inseminations were done by the same technician, and donor bulls were used consecutively throughout the breeding season. Pregnancy diagnosis was done by ultrasound images (Falco 100, 6 MHz, Pie Medical, Crawley, UK) 28 days after insemination. The SISVAR software was used in variance analysis and comparison of means by the Tukey test. Group I showed greater (P < 0.05) IM mean value (153.5 ± 27.48) compared with group II (107.94 ± 30.61), which means that this group had higher sperm motility during the time of evaluation. In addition, conception rates (0.63 ± 0.49) for group I were also higher (P < 0.05) compared with group II. Apparently semen fertility is related to the sperm kinetics measured by the IM. Mean IM values (134.0 ± 22.65 and 96 ± 22.34, groups I and II, respectively) obtained in the last illumination for each group did not differ (P > 0.05), but a tendency to differ was observed when a greater number of illuminations was done. Our data suggest that the BSL was capable of identifying spermatozoa surviving between high and low motility groups, and the sperm motility decreasing measured by the IM might be an objective approach to evaluate semen fertilization potential.
