Aesthetic ONE21 Technique for Injecting IncobotulinumtoxinA into the Forehead: Initial Experience With 86 Patients.

BACKGROUND: Treatment of upper facial lines is a common aesthetic practice; however, there is limited information on systematic tailored approaches for the treatment of forehead wrinkles using botulinum toxin A. OBJECTIVE: To describe the safety and efficacy of the ONE21 technique using incobotulinumtoxinA (INCO) for the treatment of forehead wrinkles. METHODS: Single-center, retrospective study with 86 females presenting a baseline Merz Aesthetic Scale (MAS) score ≥2 for dynamic forehead lines who had been treated with INCO using the ONE21 technique. Assessment was performed by two independent blinded raters using MAS for forehead lines (dynamic and at rest), and eyebrow positioning, based on standardized pictures taken before (baseline) and 4 (±2) weeks after treatment injection. The primary outcome was the percentage of subjects with a MAS improvement ≥2 points for dynamic forehead lines at week 4 (±2). Secondary outcomes were MAS scores for resting forehead lines and for eyebrow positioning. RESULTS: The mean age was 46.2 years, and mean total dose of INCO, 20.3 U. Most (97.7%) subjects had a MAS improvement of ≥2 points for dynamic forehead lines at week 4 (±2); 100% improved ≥1 point. MAS scores for resting and dynamic lines, and eyebrow positioning were significantly improved (P<0.001). Eyebrow positioning MAS improved ≥1 point in 56.9% of subjects, and 39.5% maintained the original shape. CONCLUSION: INCO injection using the ONE21 technique is effective and safe in treating forehead wrinkles, providing a natural result, with a customized treatment and a predictable eyebrow shape.

Biological efficiency and nutritional value of Pleurotus ostreatus cultivated in agroindustrial wastes of palm oil fruits and cocoa almonds / Eficiência biológica e valor nutricional de Pleurotus ostreatus cultivados em resíduos agroindustriais de dendê e amêndoa de cacau

The cocoa and palm oil agro-industries active in the state of Bahia, Brazil, generate high quantities of lignocellulosic wastes that could be recycled through their use in the formulation of substrates to cultivate edible mushrooms. Pleurotus ostreatus, also known as oyster mushroom, is the second most cultivated mushroom in the world due to its highly appreciated gastronomic, nutritional, and medicinal characteristics. This work evaluated the vertical mycelium growth, biological efficiency, mushroom yield, and nutritional composition of P. ostreatus produced in substrates formulated with a combination of palm oil fruit mesocarp (POFM) and cocoa almond peels (CAP) processing wastes. The substrates were formulated with the following POFM/CAP proportions (%/%): S1 ­ 86.4/9.6; S2 ­ 76.8/19.2; S3 ­ 67.2/28.8; S4 ­ 57.6/38.4, and S5 ­ 48.0/48.0. Substrates also received 3% powdered charcoal and 1% calcium carbonate. Substrates S1, S2, S3, and S4 were superior for vertical mycelium growth. S2 promoted the best biological efficiency (148.8%) and yield (560.5g·kg-1).The mushrooms produced in all substrates presented good nutritional values, although mushrooms produced using the S2 presented the highest crude protein content. Overall, S1 is the recommended substrate as it results in higher yields of nutrient rich mushrooms. Production of P. ostreatus in substrates composed of POFM and CAP represents a good alternative for recycling these wastes with potential economic and ecological benefits to regions where palm oil and cocoa are grown.(AU)

As indústrias de cacau e óleo de dendê no estado da Bahia, Brasil, geram grandes quantidades de resíduos lignocelulósicos que podem ser reciclados na formulação de substratos para o cultivo de cogumelos comestíveis. Pleurotus ostreatus ou cogumelo ostra é o segundo cogumelo mais cultivado no mundo por apresentar características gastronômicas, nutricionais e medicinais muito apreciadas. Este estudo avaliou o crescimento micelial vertical, a eficiência biológica, a produção e a composição nutricional de P. ostreatus produzido em substratos formulados com a combinação de resíduos do processamento de frutos de dendê (mesocarpo do fruto de dendê ­ MFD) e de amêndoas de cacau (tegumento de amêndoas de cacau ­ TAC). Os substratos foram formulados com as seguintes proporções de MFD e TAC (%/%): S1: 86,4/9,6; S2: 76,8/19,2; S3: 67,2/28,8; S4: 57,6/38,4 e S5: 48,0/48,0. Os substratos também receberam 3% de carvão e 1% de carbonato de cálcio. Os substratos S1, S2, S3 e S4 foram superiores quanto ao crescimento micelial vertical. S2 promoveu os melhores resultados para eficiência biológica (148,8%) e produção (560.5 g·kg-1). Os cogumelos produzidos em todos os substratos apresentaram valores nutricionais promissores. Entretanto, os cogumelos produzidos com o substrato S2 apresentaram o maior conteúdo de proteína bruta. De modo geral, S1 é o substrato recomendado por resultar na maior produção de cogumelos ricos em nutrientes. A produção de P. ostreatus em substratos compostos por MFD e TAC representa uma boa alternativa para a reciclagem desses resíduos com potenciais benefícios econômicos e ecológicos para as regiões produtoras de dendê e cacau.(AU)

Cultivo do champignon em função da temperatura / Buton mushroom cultivation in function of temperature

O cogumelo Agaricus bisporus é um cogumelo de clima temperado que requer baixa temperatura para a indução da frutificação. Essa exigência limita o seu cultivo no Brasil nos meses mais frios do ano ou exige a utilização de ambiente controlado, onerando muito a produção. Por isso, este trabalho teve como objetivo avaliar a produtividade de diferentes linhagens em função da temperatura de cultivo após a indução da frutificação. Diferentes linhagens de A. bisporus foram avaliadas quanto ao efeito da temperatura sobre a colonização do composto e a produtividade do cogumelo. As temperaturas de 21 e 25°C foram utilizadas durante a colonização do composto e, após a indução da frutificação, durante o ciclo de cultivo. Para todas as linhagens testadas, a temperatura de 25°C proporcionou maior velocidade de colonização do composto, favorecendo ciclos de cultivo mais curtos. Além disso, após a indução da frutificação a 18°C, a manutenção do ambiente de cultivo a 25°C proporcionou maior produtividade, quando comparada ao cultivo a 21°C. Para a linhagem mais produtiva, os três primeiros fluxos foram responsáveis por mais de 50% da produção total. Portanto, para um cultivo comercial em que é necessário manter volumes constantes de produção, os ciclos de cultivo poderiam ser limitados a três fluxos de produção.

The Agaricus bisporus is a button mushroom that requires low temperature to induce fruiting. This requirement limits our cultivation in Brazil during the coldest months of the year and requires the use of controlled environment. Therefore, this study aimed to assess the productivity of different strains depending on the growth temperature after induction of fruiting. A. bisporus strains were evaluated for the effect of temperature on the colonization of compost and mushroom productivity. Temperatures of 21 and 25°C were used for the substrate colonization and after induction of fruiting crop cycle. For all strains tested, temperature 25°C gave a quickly colonization of the compound, favoring shorter production cycles. Furthermore, after induction of fruiting at 18°C, maintaining the culture environment at 25°C gave a higher productivity to contrast with culture at 21°C. For the most productive strain, the first three streams were responsible for over 50% of total production. Thus, for a cash crop where it is necessary to maintain constant volumes of production, crop cycles could be limited to three productions flows.

Application of Hazard Analysis and Critical Control Points (HACCP) to the Cultivation Line of Mushroom and Other Cultivated Edible Fungi.

The Hazard analysis and critical control points (HACCP) is a preventive system which seeks to ensure food safety and security. It allows product protection and correction of errors, improves the costs derived from quality defects and reduces the final overcontrol. In this paper, the system is applied to the line of cultivation of mushrooms and other edible cultivated fungi. From all stages of the process, only the reception of covering materials (stage 1) and compost (stage 3), the pre-fruiting and induction (step 6) and the harvest (stage 7) have been considered as critical control point (CCP). The main hazards found were the presence of unauthorized phytosanitary products or above the permitted dose (stages 6 and 7), and the presence of pathogenic bacteria (stages 1 and 3) and/or heavy metals (stage 3). The implementation of this knowledge will allow the self-control of their productions based on the system HACCP to any plant dedicated to mushroom or other edible fungi cultivation.
