Diabetes mellitus (DM) is a metabolic disease in which there are high blood sugar levels. Type 2 is due to the cells of the body not responding properly to the insulin produced. The aim of this study was to evaluate the enzyme activity in glutathione peroxidase in type 2 diabetic rats induced streptozotocin Wister rats. Enzyme linked immunosorbent assay (ELISA) methods was used. Thirty-two (32) adult rats of Wister strain weighing between 120 g – 200 g of both sexes equally were used. Streptozotocin was used to induce diabetes after high fat diet. The rats were randomly grouped into 4 groups of 8 rats; group 1 are rats fed with only feed and water, group 2 were given 37 mg/kg of streptozotocin with feed and water, group 3 had 37 mg/kg of streptozotocin, feed, water and treated with 2ml of freshly prepared bitter leaf extract daily, group 4 had feed, water, 37mg/kg of streptozotocin and treated with 5 mg/kg of glibenclamide (anti diabetic drug). Severity of the induced diabetic state was assessed by daily and weekly monitoring of body weights and blood glucose levels. The result of fasting blood sugar shows a significant difference (P<0.05) at group 3(7.72±0.99) compared to group 4(9.93±1.22) in week 2.There is also a significant decrease (p<0.05) at group 3(7.72±0.99) compared to group 4(9.90±1.24) in week 3.There is also a significant decrease (p<0.05) at group 3(6.22±1.20) compared to group 46.50±0.70) in week 5. There is a significant increase (p<0.05) at group 1(7.63±0.71) compared to group 4(5.78±1.40), group 2(7.45±0.87) compared to group 4(5.78±1.40)in week 4.There is also a significant decrease in GPX activity in group at group 1(424.59±102.65) compared to group 2(307.34±75.66). There is no significant difference (p>0.05) at group 2(307.34±75.66) compared to group 3(204.31±46.51). There is also no significant difference (p>0.05) at group 2(307.34±75.66) compared to group 4(206.12±55.37). No significant difference (p>0.05) at group 3(204.31±46.51) compared to group 4(206.12±55.37). In conclusion, the result of this study suggest that bitter leaf extract reduced glucose level and has no  damage effect on the liver.

Summary. Background: Prosthetic vascular graft infection (PVGI) is a complication with high mortality. Cyanoacrylate (CA) is an adhesive which has been used in a number of surgical procedures. In this in-vivo study, we aimed to evaluate the relationship between PVGI and CA. Materials and methods: Thirty-two rats were equally divided into four groups. Pouch was formed on back of rats until deep fascia. In group 1, vascular graft with polyethyleneterephthalate (PET) was placed into pouch. In group 2, MRSA strain with a density of 1 ml 0.5 MacFarland was injected into pouch. In group 3, 1 cm 2 vascular graft with PET piece was placed into pouch and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. In group 4, 1 cm 2 vascular graft with PET piece impregnated with N-butyl cyanoacrylate-based adhesive was placed and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. All rats were scarified in 96th hour, culture samples were taken where intervention was performed and were evaluated microbiologically. Bacteria reproducing in each group were numerically evaluated based on colony-forming unit (CFU/ml) and compared by taking their average. Results: MRSA reproduction of 0 CFU/ml in group 1, of 1410 CFU/ml in group 2, of 180 200 CFU/ml in group 3 and of 625 300 CFU/ml in group 4 was present. A statistically significant difference was present between group 1 and group 4 (p < 0.01), between group 2 and group 4 (p < 0.01), between group 3 and group 4 (p < 0.05). In terms of reproduction, no statistically significant difference was found in group 1, group 2, group 3 in themselves. Conclusions: We observed that the rate of infection increased in the cyanoacyrylate group where cyanoacrylate was used. We think that surgeon should be more careful in using CA in vascular surgery.

In order to assess the influence of finishing and polishing on the surface brightness and color stability of the ceramic veneer, fifty specimens were fabricated with 10 mm diameter and 2 mm thickness using IPS E-Max Ceramic. After glazing, 10 specimens were untouched as control group, and the other 40 specimens were abraded using 125µm diamond bur to create surface roughness. Forty specimens were divided into four groups (n=10), in group 1: specimens were finished using diamond point, in group 2 specimens’ surface was polished with a polishing kit, Group 3: Each specimen surface was polished with the polishing kit as in protocol 2 and was polished a polishing past and group 4 Each specimen was glazed by heating at 621℃ for 3 minutes followed by a temperature increase of 83℃/min up to 918℃ for 30 seconds. Color measurement was performed using spectrophotometer. Color stability data were analyzed using two-way ANOVA and Tukey’s HSD test (α=0.05). For Ra values, paired-samples t-tests were used to analyze the data and compare groups. The change in L and E showed a significant difference among the study groups; (group 1, group 2, group 3 and group 4) with respect to three variables L, a and b. A significant difference was noted when compared each group with the control; however, only group 2 showed a significant difference from group 4; the remaining groups demonstrated similar findings for all three variables. The study displayed a significant impact of the finishing and polishing technique on the surface brightness and color stability of ceramic restoration. However, it was evident that combination of two or three polishing techniques which includes polish kit and glaze enhances the surface finish and adds color stability by alternating the yellow – blue axis (increase in b) and red- green axis (decrease in a).

In this study, nutritional values of silages made from seed pumpkin residues were investigated. Pumpkin residues collected from Konya region were put into silo in vacuum sacks with various additives. As additives, straw, inoculant containing lactic acid bacteria or a mixture of both in certain proportions were used. After the silos were opened, their pH was determined and then samples were taken to determine the essential fatty acid compositions and nutrient analyses were done. Natural pumpkin (Group 1), natural pumpkin + inoculant (100ppm) (Group 2), withered pumpkin + 15% straw (Group 3), withered pumpkin + 15% straw + inoculant (100ppm) (Group 4) such that the fourth group is formed. Dry matter values of pumpkin groups are Group 1 7.89%, Group 2 6.62%, Group 3 12.22% and Group 4 12.25% respectively. Their pH is 3.78 in Group 1, 3.71 in Group 2, 3.86 in Group 3 and 3.82 in Group 4. The crude protein ratio in the experimental groups was determined in the highest Group 2 (14.97%) and the lowest in Group 3 (10.56%). NDF rate was determined in the highest group 4 (49.74%) and the lowest in Group 2 (28.51%). In addition, the highest ADF rate was determined in Group 4 (37.91%) and the lowest in Group 2 (24.90%). There was a statistically significant difference between the research groups in terms of ethanol content. Acetic acid and propionic acid content was found statistically significant between groups. As a result, when the pumpkin residues are silaged, it can be used as feed material in animal feeding. In addition, it can be said that pumpkin residues can be evaluated in different areas in the high amount of Ethanol content resulting from silage production.

Epineural stitches are a means to avoid tension in a nerve suture. We evaluate this technique, relative to interposed grafts and simple neurorraphy, in a rat model. METHOD: Twenty rats were allocated to four groups. For Group 1, sectioning of the sciatic nerve was performed, a segment 4 mm long discarded, and epineural suture with distal anchoring stitches were placed resulting in slight tension neurorraphy. For Group 2, a simple neurorraphy was performed. For Group 3, a 4 mm long graft was employed and Group 4 served as control. Ninety days after, reoperation, latency of motor action potentials recording and axonal counts were performed. Inter-group comparison was done by means of ANOVA and the non-parametric Kruskal-Wallis test. RESULTS: The mean motor latency for the simple suture (2.27±0.77 ms) was lower than for the other two surgical groups, but lower than among controls (1.69±0.56 ms). Similar values were founding in both group 1 (2.66±0.71 ms) and group 3 (2.64±0.6 ms). When fibers diameters were compared a significant difference was identified between groups 2 and 3 (p=0.048). CONCLUSION: Good results can be obtained when suturing a nerve employ with epineural anchoring stitches. However, more studies are needed before extrapolating results to human nerve sutures.

Objective: In this study, the effect of tracheal diverticula (TD) on chest anthropometry and its relation with chronic obstructive pulmonary disease (COPD) was evaluated. Method: Between January 2019 and March 2020, 995 patients who underwent chest CT were retrospectively analyzed and TD was detected in 31 cases. Group 1 is only TD, Group 2 is TD + COPD, Group 3 is only COPD, Group 4 is defined as control group. We measured the localization, size, the distance to carina and vocal cord of TDs. In all groups chest diameters at T4 and T9 levels were measured as transverse and vertical plans. Results: TDs detected mostly at the T2 and T3 levels. In Group 1 and Group 2, there was a statistically significant difference the distance to TD of vocal chords. A statistically significant difference was found between Group 1 and Group 3 only in the vertical diameter at the T4 and T9 levels. Conclusion: We observed that COPD effect TD location and also TD had opposite effect on anteroposteriorly increasing chest parameters in COPD. Precence of TD is essential on COPD patients about thorax anthropometry. Keywords: Tracheal diverticulum; antropometry; radiology; COPD; chest diameter

ABSTRACT Forty-eight extracted maxillary anterior teeth instrumented with ProTaper system to apical preparations 0.25, 0.40 and 0.60 mm (n = 16 each) were divided into six groups for filling as following: Group 1: Apical preparation 25/100 + gutta-percha/AH Plus sealer, group 2: Apical preparation 25/100 + Resilon/Real Seal, group 3: Apical preparation 40/100 + gutta-percha/AH plus sealer, group 4: Apical preparation 40/100 + Resilon/Real Seal, group 5: Apical preparation 60/100 + gutta-percha/AH plus, group 6: Apical preparation 60/100 + Resilon/Real Seal. All teeth were filled using the warm vertical technique. Horizontal sections at 1, 2 and 3 mm from the apex were observed by SEM under 200 × magnification. Sections were digitally photographed under a stereomicroscope and the images were transferred to a compatible PC for image analysis. The surface area of voids were calculated and compared at all levels; using the Kruskal-Wallis test with Sidak correction and Mann-Whitney U test (p > 0.05). Comparisons within each group (gutta-percha/AH plus and Resilon/Real Seal) showed the presence of voids but there was no significant difference between any level of sectioning for apical preparations of 25 and 40 (p > 0.05). The only difference was in the groups prepared to size 60 and filled with Resilon/ Real Seal which showed significantly more voids than the group filled with gutta-percha/AH plus and especially at the 3 mm level. Conclusion The system Resilon/Real Seal did not achieve better results in terms of sealing ability in the apical third when compared to the conventional gutta-percha/AH plus sealing system.

Many studies have looked at benefits of breastfeeding for the baby and, less frequently, the mother. Though many women find breastfeeding difficult, few studies have looked at the potential costs of breastfeeding for this group. From January 19th 2015 through April 18th 2015, the total of 1,980 Serbian mothers completed an on-line survey consisting of 74 questions which addressed their satisfaction with various areas of life. Mothers were divided into four groups depending on their breastfeeding experience: those who enjoy breastfeeding (Group 1), those who breastfeed despite finding it difficult (Group 2), those who do not breastfeed because they find it difficult, but otherwise would (Group 3) and those who do not breastfeed because ?it is their choice? (Group 4). There were 1,238 women (53.2%) in Group, 1, 546 (23.4%) in Group 2, 147 (6.3%) in Group 3 and 49 (2.1%) in Group 4. Group 2 scored lower than Group 1 on 25 out of 26 indicators of satisfaction. When these 26 indicators were averaged, there was a significant difference in the average scores between Group 1 (M = 6.87, SD = 1.10) and Group 2 (M = 6.33, SD = 1.20). Group 3 scored higher than Group 2 on 19 out of 26 indicators. There is a remarkably consistent difference in satisfaction across many areas of life between women who breastfeed joyfully and those who do it out of a sense of duty. As public pressure on women to breastfeed mounts, distinction between these two kinds of breastfeeding experiences should be kept in mind.
