Brachioplasty by power-assisted liposuction and fat transfer: A novel approach that obviates skin excision
Background Current brachioplasty techniques include excisional surgery alone or in combination with liposuction. These techniques are associated with poor outcomes, such as residual contour deformities and unfavorable scarring. Objectives The authors proposed a new classification system and treatment algorithm for brachial ptosis and described their experience with power-assisted liposuction and lipofilling to treat brachial ptosis without excisional surgery. Methods Ninety-five patients with grades 1, 2, or 3 brachial ptosis who underwent brachioplasty were evaluated in a prospective study. Power-assisted liposuction was applied to the posterior arm and para-axillary region, and power-assisted lipofilling was applied to the so-called "bicipital triangle" of the medial arm. Results The patients' mean age was 39 years, mean body mass index was 28 kg/m2, mean lipoaspirate volume was 240 mL per arm, and mean fat-injection volume was 110 mL per side. The mean operating time was 50 minutes, and the average follow-up period was 24 months. Hematoma developed in 2 patients who underwent brachioplasty in combination with another body contouring procedure (1 abdominal hematoma and 1 thigh hematoma; 2.1% complication rate). No other complications were recorded. Conclusions Brachioplasty by means of power-assisted liposuction and lipofilling is a safe and reliable option that obviates excisional surgery in patients with mild to moderate brachial ptosis.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
Power-assisted gluteal augmentation: A new technique for sculpting, harvesting, and transferring fat
Background: A simple and reproducible surgical technique for gluteal shaping and augmentation with autologous fat is needed. Objectives: The authors describe a novel approach to large-volume gluteal augmentation that combines power-assisted liposculpting and fat harvesting of the zones around the buttock with autologous fat transfer. Methods: One hundred ten patients who underwent gluteal augmentation were evaluated in a prospective study. Liposculpting and fat harvesting were performed with power-assisted liposuction. Fat then was transferred to the gluteal region with simultaneous power-assisted vibration and tunnelization. A questionnaire to assess patient satisfaction was administered at 6 months postoperatively. Results: The mean body mass index of the patients was 30 kg/m2 (range, 26-36 kg/m2). Liposuction volumes ranged from 1400 to 5000 mL, and injection volumes ranged from 300 to 900 mL per side for each session. Operating times ranged from 60 to 120 minutes. Patients were monitored for an average of 20 months (range 12-48 months). Complications included a burning sensation in 5 of 110 patients (4.5%), persistent swelling in the lower back in 3 patients (2.7%), and a mild infection in 1 patient (0.9%). Conclusions: Power-assisted gluteal augmentation with autologous fat is an efficient, safe, and reproducible procedure that produces an aesthetically pleasing gluteal projection and contour.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
Efeitos alelopĂĄticos de extratos vegetais na germinação, colonização micorrĂzica e crescimento inicial de milho, soja e feijĂŁo Allelopathic effects of plant aqueous extracts on germination, mycorrhization and Initial growth of corn, soybean and bean
Restos vegetais e liteira podem interferir no desenvolvimento de plantas. Este trabalho objetivou avaliar os efeitos alelopĂĄticos de extratos aquosos de Pinus sp., milheto (Pennisetum americanum (L.) Leeke) e mucuna (Stizolobium aterrimum Piper & Tracy) sobre a germinação, colonização micorrĂzica e crescimento inicial de milho (Zea mays L.), soja (Glycine max L.) e feijĂŁo (Phaseolus vulgaris L.). Os extratos foram elaborados utilizando folhas trituradas. O experimento in vitro empregou papel Germitest umedecido com extratos ou ĂĄgua destilada por sete dias. O experimento em casa de vegetação teve esquema fatorial 3 x 3 x 4, com quatro repetiçÔes: trĂȘs espĂ©cies vegetais (soja, milho e feijĂŁo), trĂȘs extratos aquosos (Pinus, milheto e mucuna) e quatro doses de extrato (0,0; 0,5; 1,0; e 2,0 kg L-1). O substrato foi Latossolo Vermelho coletado no municĂpio de SelvĂria-MS, no bioma Cerrado. ApĂłs a semeadura, os vasos receberam, a cada cinco dias, por 45 dias, 50 mL dos extratos. Para a soja, extratos de mucuna e milheto diminuĂram o comprimento do hipocĂłtilo e da radĂcula e os de Pinus aumentaram esses comprimentos. Em feijĂŁo, o extrato de Pinus diminuiu o comprimento do hipocĂłtilo e da radĂcula, mas os extratos de mucuna e milheto aumentaram-no. O extrato do milheto reduziu a percentagem e a velocidade de germinação em feijĂŁo. Todos os extratos reduziram a colonização micorrĂzica e o nĂșmero de esporos de fungos micorrĂzicos arbusculares em soja, milho e feijĂŁo.<br>Plant residues and litter may affect the plant growth. The objective of this study was to evaluate the allelopathic effects of aqueous extracts of pine (Pinus sp.), millet [Pennisetum americanum (L.) Leeke] and velvet bean (Stizolobium aterrimum Piper & Tracy) on germination, mycorrhizal colonization and initial growth of corn (Zea mays L.), soybean (Glycine max L.) and bean (Phaseolus vulgaris L.). Extracts of ground leaves were prepared. For the in vitro seven day- germination test, pH - neutral paper was previously wetted with the aqueous extracts or distilled water. The greenhouse experiment was arranged in a 3 x 3 x 4 factorial design, with four replications: three plant species (soybean, corn and bean), three aqueous extracts (Pinus, millet and velvet bean) and four extract doses (0.0; 0.5; 1.0 and 2.0 kg L-1). A Red Latossol (Oxisol) collected in SelvĂria, state of Mato Grosso do Sul, in the Cerrado biome was used as substrate. After sowing in pots, 50 mL of the aqueous extracts was applied every 5 days, during 45 days. Opposite to pine, extracts of velvet bean and millet reduced the hypocotyl and root length in soybean. In common bean, pine extract reduced hypocotyl and root length, contrasting to velvet bean and millet. Millet extract decreased the germination percentage and germination rate of beans. All plant extracts reduced mycorrhization and the number of spores of arbuscular mycorrhizal fungi on soybean, maize and common bean
