For nine months we monitored the periodontal health of 81 adolescents undergoing orthodontic treatment with fixed appliances, to determine whether daily use of a brush-on 0.4% SnF 2 gel would be better than toothbrushing alone in maintaining periodontal health in these patients, and whether a gel supplying a high percentage of available Sn2+ ion would be more beneficial than a gel supplying a low percentage of available Sn2+ ion. The subjects were matched for age and sex and placed into a control group, which used toothbrushing alone, and two treatment groups, which used toothbrushing supplemented with daily use of a SnF2 gel. One treatment group used a gel with 98% available Sn2+ ion twice daily for the entire nine months. The other treatment group used a gel with less than 2% available Sn2+ once a day for six months, then twice a day for the remaining three months of the study. Clinical assessments (Plaque Index, Gingival Index, Bleeding Tendency, pocket depth, and coronal staining) were made before appliances were placed and at one, three, six, and nine months after appliances were placed. Results indicated that the group using the high-availability Sn 2+ gel twice daily had significantly lower Gingival Index and Bleeding Tendency scores at the one-, three-, six-, and nine-month examinations than did the control group. The group using the low-availability Sn2+ gel showed no significant differences in these assessments from the control group. Neither treatment group showed significant differences from the control group in Plaque Index or pocket depth. In the group using the high-availability Sn2+ gel, one subject developed mild coronal staining, and two developed moderate staining.

The objective of this study was to obtain a proper ratio between the volume of water and the weight of shrimp heads in order to increase the protein content in shrimp sticks. The design used in the study was a completely randomized design (CRD) with treatment groups of 1:1, 1:2, and a control group without the addition of shrimp head extract. Water content, protein content, ash content and organoleptic test were the parameters measured. The results of the study show that the addition of white shrimp head extract in the treatment group with a 1: 1 ratio produced shrimp sticks with a protein content of 12.22%; in the treatment group with a 1: 2 ratio 13.44%; and in the control group without the addition of shrimp head extract only 5.54%. The addition of shrimp head extract also produced more preferred flavor compared to the one without the addition of the extract.

Background: Hypertension is probably the most important public health problem around the world. People with periodontal disease may be at greater risk of hypertension. The inflammatory effects of periodontal disease help to promote endothelial dysfunction in arteries which may lead to changes in blood pressure. Salivary MMP-8 has been associated with both periodontal disease and prevalent hypertension. Aim of study: This study was conducted to measure salivary matrix metalloproteinase - 8, in relation to periodontal health condition among a group of patients with hypertension in comparison with control group. Materials and methods: Ninety subjects, aged 45-50 years old were included in this study, seeking treatment for chest pain in Ibn-AlBaytar center for cardiac surgical treatments in Baghdad, Iraq. The subjects were divided into study group (45 patient) who were diagnosed to be a hypertensive patient, and a control group (45 subject), with no hypertension. Plaque status was evaluated according to the Silness and Loe, probing pocket depth and clinical attachment level. Unstimulated saliva was collected from all subjects to analyses MMP-8. Result: A high mean value of plaque index, clinical attachment level and probing pocket depth for the study group than the control group with statistically no significant difference. In addition to that, a significant positive correlation between the plaque index and the clinical attachment level among both groups. Salivary MMP-8 level showed a higher level in the study group than in the control group, with statistically significant difference between groups, and a significant positive correlation was detected between salivary MMP-8 with plaque index, among study group, Conclusions: Higher percentage of periodontal diseases was found among patients with blood hypertension. In addition, high level of salivary MMP-8 is potentially associated with periodontal status of the study group.

Invisalign has improved periodontal health in comparison to traditional metal wire braces. Due to a growing interest in attaining better teeth esthetics, there are more adults seeking Invisalign treatment. Ten percent carbamide peroxide (CP) breaks down to 6.5% urea and 3.5% hydrogen peroxide, which elevates oral pH, removes stains, and diminishes caries by inhibiting plaque formation. The aim of this study is to investigate whether 10% CP use during Invisalign treatment can enhance tooth shade esthetics while decreasing plaque levels and improving gingival health indices. Twenty-eight patients at Western University dental center undergoing Invisalign were assigned to two groups where the experimental group applied daily bleaching material (10% CP, Ultradent Inc., South Jordan, UT, USA), while the control group did not for 4 weeks. Tooth shade, plaque index (PI), and gingival index (GI) were assessed at baseline and in 2-week intervals for 6 weeks. Results showed that 10% CP had significant change in tooth shade over the 2- and 4-weeks periods (p < 0.05) and significantly reduced plaque and gingival indices (p < 0.05), with minimal to no relapse after 2 weeks post-op. Thus, applying CP at 10% may be a useful application during Invisalign treatment in improving teeth shade and overall gingival health.

Burn therapy involves elimination of causative factors and symptomatic therapy. Kenitu leaves (Chrysophyllum cainito L.) are known to contain β-amylin acetate, Gallic acid, ursolic acid, quercetin, β-sitosterol, and other substances that have the potential to be antibacterial, antioxidant, and anti-inflammatory. The use of kenitu leaves (Chrysophyllum cainito L.) as an alternative to wound healing has low side effects and is easy to obtain, especially in Jember Regency. The aim of this study was to examine the effect of kenitu leaves (Chrysophyllum cainito L.) leaf extract gel on re-epithelialization in buccal mucosal burns of wistar rats. This type of research is experimental laboratories. This research used 32 samples which divided into four control groups and four treatment groups. Burns are made on the left buccal mucosa. In the control group the CMC placebo gel was given and the treatment group was given 2% leaf extract gel. Euthanasia was performed on days 4, 7, 10, and 13 then histological preparations were made. Measurement using software optilab viewer 2.2 and image raster 3.0. The average yield of epithelial thickness was lowest in the control group on day 4 and highest in the treatment group on day 13. The results of the One Way Anova statistical test showed a significant difference in epithelial thickness between the control group and the treatment group. This study proved that the 2% leaf extract can accelerate the process of reepithelialization in the healing of wistar mucosal mucosal burns.

Abstract Objective: To evaluate the effectiveness of diode laser gingivectomy as an adjunct to nonsurgical periodontal treatment in the management of periodontal health among patients receiving fixed orthodontic appliance therapy (FOAT). Materials and Methods: Thirty patients undergoing FOAT with gingival enlargement were block randomized into two treatment groups. The test group received diode laser gingivectomy (940-nm diode laser, ezlase, Biolase Technology Inc) as an adjunct to nonsurgical periodontal treatment. The control group received nonsurgical periodontal treatment only. For both groups, five periodontal parameters were assessed at baseline, 1 month, 3 months, and 6 months: Plaque Index, Gingival Index, bleeding on probing, probing pocket depth, and Gingival Overgrowth Index. Intra- and intergroup variations in the periodontal parameters were determined over time. Results: Both groups showed statistically significant improvements in periodontal health over the study period (P &lt; .05). However, significant improvements in periodontal health were evident earlier among the test group subjects (P &lt; .05). The magnitude of improvement in periodontal health compared to baseline was greater in the test group than in the control group for Gingival Overgrowth Index at 1 month (P &lt; .001) and 3 months (P &lt; .05), Gingival Index at 3 months (P &lt; .05) and 6 months (P &lt; .05), and probing pocket depth at 1 month (P &lt; .05). Conclusions: Nonsurgical periodontal management with or without the adjunct use of lasers can be effective in the management of gingival health problems among patients receiving FOAT. The adjunctive use of lasers can produce an earlier and greater improvement in gingival health.

The soybean aphid Aphis glycines Matsumura (Hemiptera: Aphididae) is a primary pest of soybeans and poses a serious threat to soybean production. Our studies were conducted to understand the effects of different concentrations of insecticides (imidacloprid and thiamethoxam) on A. glycines and provided critical information for its effective management. Here, we found that the mean generation time and adult and total pre-nymphiposition periods of the LC50 imidacloprid- and thiamethoxam-treatment groups were significantly longer than those of the control group, although the adult pre-nymphiposition period in LC30 imidacloprid and thiamethoxam treatment groups was significantly shorter than that of the control group. Additionally, the mean fecundity per female adult, net reproductive rate, intrinsic rate of increase, and finite rate of increase of the LC30 imidacloprid-treatment group were significantly lower than those of the control group and higher than those of the LC50 imidacloprid-treatment group (P < 0.05). Moreover, both insecticides exerted stress effects on A. glycines, and specimens treated with the two insecticides at the LC50 showed a significant decrease in their growth rates relative to those treated with the insecticides at LC30. These results provide a reference for exploring the effects of imidacloprid and thiamethoxam on A. glycines population dynamics in the field and offer insight to agricultural producers on the potential of low-lethal concentrations of insecticides to stimulate insect reproduction during insecticide application.

Anaerobic  exercise is a high-intensity exercise that needs quick energy supplies obtained in a very short time. However, this exercise may result in tissue hypoxia which is characterized by the increase of HIF-1α concentration. The presence of HIF-1α will induce the secretion of VEGF and, eventually, trigger angiogenesis. Nevertheless, it is still unclear whether anaerobic exercise will also cause hypoxia in which this condition will increase the concentration of VEGF in brain tissues. The aim of this study was to find out the effect of anaerobic exercise frequency towards VEGF concentration of Wistar rat brain tissues.  Brain tissues were taken from rats treated with anaerobic exercise using treadmill. This exercise was given in different frequencies; one time, three times, and seven times a week.  The data collected were analyzed using independent t-test. The results of this study showed that anaerobic  exercise done once a week could significantly increase VEGF concentration (p &lt; 0.05) if compared with the one in control group (95.21 ± 31.99 v.s. 63.36 ± 11.01 pg/mL). Meanwhile, VEGF concentration of treatment groups given exercise three times a week (47.97 ± 10.68 pg/mL) and seven times a week (40.56 ± 13.98 pg/mL) showed a significant decrease if compared with that of control group (63.36 ± 11.01 pg/mL). Anaerobic  exercise affected VEGF concentration as an indicator of angiogenesis in brain tissue of wistar rats.

Benzopyrene is a polycyclic aromatic hydrocarbons (PAHs) compound that can cause transformation of normal cells into malignant in order to its genotoxic,mutagenic,and carsinogenic ability.  DNA mutation in tumor suppressor genes p53 make cells immortal which results in cell transformation and develops into malignancies. This study consist of five groups including the control group (without benzopyrene injection) and 4 treatment groups injected with benzopyrene each for 4 weeks (P1), 6 weeks (P2), 8 weeks (P3) and 10 weeks (P4).  Therefore, the mutant p53 expression was calculated and analyzed statistically with the One Way Anova Test. There was signifficance difference in mutant p53 expression of oral transformed epithelium cell injected by benzopyrene (p=0.000) and the highest expression was at 10th week. It can be concluded that the mutant P53 expression of oral transformed epithelium cells in rats was increased after injected by benzopyrene
