“…Annatto (Bixa orellana L.) is a native plant of the tropical regions of America [18]. Annatto seeds are typically composed of 50% carbohydrate, 12-17% protein, 9-13% water, 5-7% ash, 2-5% lipid, and 1-6% various pigments [19].…”

Annatto Oil Loaded Nanostructured Lipid Carriers: A Potential New Treatment for Cutaneous Leishmaniasis

et al. 2021

Annatto (Bixa orellana L.) is extensively used as food pigment worldwide. Recently, several studies have found it to have healing and antioxidant properties, as well as effective action against leishmaniasis. Therefore, the purpose of this study was to incorporate the oil obtained from annatto seeds into a nanostructured lipid carrier (NLC) and evaluate its physicochemical properties and biological activity against Leishmania major. Nanoparticles were prepared by the fusion-emulsification and ultrasonication method, with the components Synperonic™ PE (PL) as the surfactant, cetyl palmitate (CP) or myristyl myristate (MM) as solid lipids, annatto oil (AO) (2% and 4%, w/w) as liquid lipid and active ingredient, and ultra-pure water. Physicochemical and biological characterizations were carried out to describe the NLCs, including particle size, polydispersity index (PDI), and zeta potential (ZP) by dynamic light scattering (DLS), encapsulation efficiency (EE%), thermal behavior, X-ray diffraction (XRD), transmission electron microscopy (TEM), Electron Paramagnetic Resonance (EPR), cytotoxicity on BALB/c 3T3 fibroblasts and immortalized human keratinocyte cells, and anti-leishmaniasis activity in vitro. Nanoparticles presented an average diameter of ~200 nm (confirmed by TEM results), a PDI of less than 0.30, ZP between −12.6 and −31.2 mV, and more than 50% of AO encapsulated in NLCs. Thermal analyses demonstrated that the systems were stable at high temperatures with a decrease in crystalline structure due to the presence of AOs (confirmed by XRD). In vitro, the anti-leishmania test displayed good activity in encapsulating AO against L. major. The results indicate that the oily fraction of Bixa orellana L. in NLC systems should be evaluated as a potential therapeutic agent against leishmaniasis.

“…No desenvolvimento da aveia, o zoneamento agrícola é a recomendação que indica as melhores condições de desenvolvimento de uma espécie agronômica, levando em consideração aspectos de solo, temperatura do ar e precipitação pluviométrica (Wollmann & Galvani, 2013;Santos & Martins, 2016;Mapa, 2017;Aparecido, et al, 2018). Entretanto, esta recomendação não leva em consideração as condições de capacidade de infecção e evolução das doenças, até porque ainda no senso comum, o uso de fertilizantes e agrotóxicos é considerado um manejo de rotina na agricultura.…”

A aveia branca é uma espécie de inverno com inúmeros benefícios aos sistemas de cultivo e na alimentação animal e humana. É reconhecida como alimento nutracêutico pelos benefícios à saúde. Esta condição tem promovido o aumento das áreas de cultivo buscando atender a demanda, porém, favorecendo o surgimento de doenças fúngicas, responsáveis por danos expressivos na produtividade e qualidade de grãos. A ferrugem da folha (Puccinia coronata f. sp avenae) e a helmintosporiose (Drechslera avenae (Eidam) Sarif) são as mais relevantes pela sua agressividade. Estas doenças não são controladas satisfatoriamente pela resistência genética e sua ocorrência e agressividade está relacionada a presença de ambiente favorável ao desenvolvimento dos fungos, hospedeiro suscetível e patógeno virulento. O uso de fungicida tem sido a alternativa mais eficiente de controle, na garantia de produtividade com retorno econômico ao agricultor. Entretanto, o uso de agrotóxicos tem gerado discussões acerca dos efeitos adversos ao ambiente, a segurança alimentar e a saúde pública, condição que reforça a busca por sistemas agrícolas mais sustentáveis. Esta revisão busca apresentar uma profunda discussão acerca dos agrotóxicos e alternativas mais sustentáveis que possam reduzir e/ou evitar a incidência e severidade de doenças fúngicas na aveia. Dentre as alternativas, a discussão engloba duas potenciais tecnologias de manejo, a semeadura envolvendo zonas de escape à restrição ao desenvolvimento dos fungos e uso de indutores abióticos de resistência por silício e potássio.

“…This helps in the rational planning of agricultural to reduce climate-related risks (Wang et al 2023). Previous agroclimatic suitability studies predominantly focused on open-air agriculture, such as the soybean-maize double crop system (Nóia Júnior and Sentelhas 2019) and annatto production (Aparecido et al 2018) in Brazil. Trnka et al (2021) assessed agroclimatic changes in the Czech Republic, and temperature and precipitation are the most crucial climate elements to be considered.…”

In China, more than two-thirds of protected cultivation occurs in low-tech facilities with limited ability to withstand adverse weather conditions. However, the specific meteorological factors that hinder facility agriculture production in various locations remain unclear. Here, we evaluated temperature and sunlight for assessing facility agriculture suitability in mainland China across different transplanting dates and ENSO phases (El Niño, La Niña, and Neutral) and to determine the optimal transplanting window. This aids in reducing climatic risks, and enhancing adaptation to changing climates. The results showed that growth cycles starting from March to June provide suitable temperature and sunlight, making them ideal transplanting window for many parts of northern China. However, both El Niño and La Niña significantly increased the high-temperature days and shortened the optimal transplanting window. For growth cycles starting from July to the following January, low temperatures are the primary factor limiting facility agriculture production in northern and western China. In southern China, sparse sunlight is the primary limiting factor year-round, and El Niño exacerbates this, particularly for growth cycles starting from September to November. This combined assessment of major meteorological factors, transplanting dates, ENSO phases, and regions, can assist decision-makers and growers in adapting to the changing climate and minimizing production risks.
