The focus of this study was to evaluate the presence and type of carbohydrates and phenolic molecules inaqueous extract (Aq-E) of Alternanthera brasiliana fresh leaves and its antioxidant and antimicrobial activities and cytotoxicity in vitro. The amount and types of the carbohydrates were measured by colorimetric and TLC methods. Phenolic compounds was detected by colorimetric assay and analysed by HPLC profiles. The antioxidant activity was evaluated by ABTS and Phosphomolybdenum methods. Antimicrobial activity was tested by microdilution method using microorganism models and antibiotic as positive control, the cytotoxicity in vitro was tested using Artemia salina. The results showed the presence of high amount of total sugars and uronic acids. TLC chromatograms showed mainly D-glucose, D-fructose, oligosaccharides and uronic acids in the Aq-E and a sugar alcohol in the methanolic extract. The colorimetric determination showed high concentration of phenolic compounds, which were visualised on the HPLC profiles, such as chemical markers of the Amaranthaceae family and several phenolic acids and flavonoids. The Aq-E demonstrated optimal antioxidant activities. The most important results were the excellent antibacterial and bactericidal activities against Mycobacterium megmatis (MIC = 15.6 µg/mL and MBC = 1000 µg/mL) and antimicrobial activity against Candida albicans (MIC = 31.2 µg/mL) and low cytotoxicity. Further possibilities for this plant extract will be to improve the pharmacological potential for developing new herbal medicines and possibly to study its association to allopathic antibiotics for prevention or treatment of infection diseases.

Objective: The number of three-piece maxillary osteotomies has increased over the years; however, the literature remains controversial. The objective of this study was to evaluate the skeletal stability of this surgical modality compared with that of one-piece maxillary osteotomy. Methods: This retrospective cohort study included 39 individuals who underwent Le Fort I maxillary osteotomies and were divided into two groups: group 1 (three pieces, n = 22) and group 2 (one piece, n = 17). Three cone-beam computed tomography scans from each patient (T1, pre-surgical; T2, post-surgical; and T3, follow-up) were used to evaluate the three-dimensional skeletal changes. Results: The differences within groups were statistically significant only for group 1 in terms of surgical changes (T2-T1) with a mean difference in the canine region of 3.09 mm and the posterior region of 3.08 mm. No significant differences in surgical stability were identified between or within the groups. The mean values of the differences between groups were 0.05 mm (posterior region) and –0.39 mm (canine region). Conclusions: Our findings suggest that one- and three-piece maxillary osteotomies result in similar post-surgical skeletal stability.
