Dental procedures produce a large amount of spatter and aerosols that create concern for the transmission of airborne diseases, such as Covid-19. This study established a methodology with the objective of evaluating new associated strategies to reduce the risk of cross-transmission in a health environment by simulating spread of potentially contaminated dispersion particles (PCDP) in the environment. This crossover study, was conducted in a school clinic environment (4 clinics containing 12 dental chairs each). As a positive control group (without barriers), 12 professionals activated at the same time the turbine of dental drill, for one minute, with a bacterial solution (Lactobacillus casei Shirota, 1.5x108 CFU/mL), which had been added in the cooling reservoir of the dental equipment. In the experimental groups, the professionals made use of; a) an individual biosafety barrier in dentistry (IBBD) which consists of a metal support covered by a disposable PVC film barrier; b) a Mobile Unit of Disinfection by Ultraviolet-C, consisting of 8 UV lamps-C of 95W, of 304μW/cm2 of irradiance each, connected for 15 minutes (UV-C) and; c) the association between the two methods (IBBD + UV-C). In each clinic, 56 Petri dishes containing MRS agar were positioned on the lamps, benches and on the floor. In addition, plates were placed prior to each test (negative control group) and plates were also placed in the corridor that connects the four clinics. In the groups without barrier and IBBD + UV-C the passive air microorganisms in Petri dishes was also evaluated at times of 30, 60, 90 and 120 minutes after the end of the dental’s drill activation. The mean (standard deviation) of CFU of L. casei Shirota for the positive control group was 3905 (1521), while in the experimental groups the mean using the IBBD was 940 (466) CFU, establishing a reduction on average, of 75% (p<0.0001). For the UV-C group, the mean was 260 (309) CFU and the association of the use of IBBD + UV-C promoted an overall average count of 152 (257) CFU, establishing a reduction on average of 93% and 96%, respectively (p<0.0001). Considering these results and the study model used, the individual biosafety barrier associated with UV-C technology showed to be efficient strategies to reduce the dispersion of bioaerosols generated in an environment with high rate of PCDP generation and may be an alternative for the improvement of biosafety in different healthy environment.

BACKGROUND: Mastitis is an inflammation of the breast tissue, usually caused by bacteria. Mastitis stimulates pro-inflammatory cytokines. The cytokine interleukin-1β (IL-1β) is a crucial mediator of the inflammatory response. This cytokine has adverse effects of hosting immunity that mediates resistance to pathogens and also exacerbates damage during chronic disease and acute tissue injury. Scaevola taccada (Gaertn.) Roxb. has been used as an ethnomedicine for healing sores in several provinces in Indonesia. AIM: This study aimed to assess the profile of pro-inflammatory cytokine IL-1β through the treatment effect of leaf extracts of S. taccada (Gaertn.) Roxb. as adjuvant for healing mastitis. METHODS: This study was a true control group experiment using the pre-test-post-test control design aimed to measure the effect of hydroalcoholic compounds in leaf extracts of S. taccada on the systemic pro-inflammatory activity of interleukin-1β (IL-1β). The treated animals were 18 mice of Sprague Dawley strain induced by Staphylococcus aureus. These treated mice were divided into three groups in which each group consisted of six mice. The mice in the Group I (negative control) were given 1 ml aquabides/250 g body weight, those in the Group II (positive control) were delivered with 9.6 mg/ml amoxicillin/250 g body weight, and those in the Group III (experimental) were given 9.6 mg amoxicillin/250 g body weight + 400 mg/ml leaf extracts of S. taccada/g body weight for 5 days, respectively. Pathological examinations were carried out from the inflamed tissues to prove the healing process of the treated mice. IL-1Β levels were determined using the enzyme-linked immunosorbent assay method. Data were analyzed using ANOVA and post hoc tests. RESULTS: There were statistically significant differences of IL-1β levels after the administration of leaf extracts of S. taccada among all the treated mice groups at p < 0.05. The Group III had the lowest IL-1β level with the mean value ± 1.45 pg/ml compared to the IL-1β level in the Group II (positive control) with the mean value ± 3.82 pg/ml and the IL-1β level in the Group I (negative control) with the with mean value ± 5.22 pg/ml. The pathological analysis of breast tissues of the treated mice proved that leaf extracts of S. taccada (Gaertn Roxb.) could reduce damaged tissues, cellular infiltration, and subcutaneous edema induced by this pathogenic microorganism. CONCLUSION: Leaf extracts of S. taccada had a significant function as adjuvant for healing mastitis by reducing pro-inflammatory cytokine IL-1β.

Introduction The aim of this in vitro study was to assess and compare the effect of different intermediary bases on microleakage between tooth and a nanocomposite interface in Class II box cavities in primary teeth. Methods Standard Class II box cavities were prepared in 52 primary molars and randomly divided into 9 groups according to the intermediary base used (Multicore Flow, Fuji II LC, SDR, Smart Dentin Replacement, and Biodentine). All specimens were subjected to thermocycling and prepared for microleakage testing and evaluation. Results There was significant difference in the mean ranks of microleakage between the 9 groups, which was observed in the gingival side (p<0.0001) and the occlusal side (p<0.0001). The mean ranks microleakage was significantly higher with experimental SDR, experimental Multicore Flow, and positive control materials when compared with the other 6 groups. The microleakage mean ranks were statistically significantly lower in experimental Fuji II LC, experimental Biodentine, and all negative control groups when compared with the other 3 groups. Conclusions Microleakage is affected by the application of intermediate material. Experimental Biodentine and Fuji II LC showed the lowest microleakage while experimental SDR and experimental Multicore Flow showed the highest microleakage.

Forty-eight goats naturally infected with gastrointestinal nematodes were randomly divided into four groups (n=12): negative control (G1) (untreated), positive control (G2) (treated with doramectin, 1 mL/50 Kg b.w.), and G3 and G4 treated with 2.5 and 5 mg/Kg b.w. of a leaf aqueous extract ofCaesalpinia pyramidalis(CP). Fecal and blood samples were regularly collected for the evaluation of fecal egg count (FEC), hematological and immunological parameters to assess the anthelmintic activity. In treated animals with CP, there was noted a significant reduction of 54.6 and 71.2% in the mean FEC (P<0.05). An increase in IgA levels was observed in G3 and G4 (P<0.05), during the experimental period, suggesting that it was stimulated by the extract administration. In conclusion, the results showed that CP provoked a protective response in infected animals treated with them. This response could be partly explained by the CP chemical composition.

A high-fat diet can increase lipoprotein levels, total cholesterol, (Low Density Lipoprotein) LDL, and triglycerides. Starfruit has saponin and flavonoid compounds which are expected to reducing LDL cholesterol levels. The aim of the study was to determine the effect of starfruit juice on lowering the blood cholesterol LDL of Wistar rats fed with high-fat diet. Experimental study with post-test only control group design. As many as 24 male white rats from the Wistar strain were divided into 3 groups: negative control groups (K-) that were given standard feed for 28 days; positive control group (K+) who were given a high-fat diet for 28 days; the treatment group (KP) was given a high-fat diet for 28 days and on the 15th day 28th they were given a starfruit juice with a dose of 4ml / 200grBB / day. Day 29 measured LDL cholesterol. The statistic test showed a significant increase in LDL cholesterol levels (p=0.001) in the positive control group (x=12.125±2.642 mg/dL) compared to the negative control group (x=7.625±1.506 mg/dL). There was no significant different the mean cholesterol level of the treatment group (x=11±1.927) compared to the mean LDL cholesterol level of the positive control group (x=12.125±2.642). A high-fat diet significantly increases the mean LDL cholesterol level. Starfruit juice did not significantly reduce LDL cholesterol level.
