Abstract
Electrospinning emerged as a promising technique to produce scaffolds for cultivated meat in function of its simplicity, versatility, cost-effectiveness, and scalability. Cellulose acetate (CA) is a biocompatible and low-cost material that support cell adhesion and proliferation. Here we investigated CA nanofibers, associated or not with a bioactive annatto extract (CA@A), a food-dye, as potential scaffolds for cultivated meat and muscle tissue engineering. The obtained CA nanofibers were evaluated concerning its physicochemical, morphological, mechanical and biological traits. UV-vis spectroscopy and contact angle measurements confirmed the annatto extract incorporation into the CA nanofibers and the surface wettability of both scaffolds, respectively. SEM images revealed that the scaffolds are porous, containing fibers with no specific alignment. Compared with the pure CA nanofibers, CA@A nanofibers showed increased fiber diameter (420 ± 212 nm vs. 284 ± 130 nm). Mechanical properties revealed that the annatto extract induces a reduction of the stiffness of the scaffold. Molecular analyses revealed that while CA scaffold favored C2C12 myoblast differentiation, the annatto-loaded CA scaffold favored a proliferative state of these cells. These results suggest that the combination of cellulose acetate fibers loaded with annatto extract may be an interesting economical alternative for support long-term muscle cells culture with potential application as scaffold for cultivated meat and muscle tissue engineering.

Abstract
Dengue (DENV), Zica virus (ZIKV), and Chikungunya fever (CHIK) are tropical diseases that have caused a lot of problems in general worldwide. Transmitted by mosquitoes of the species Aedes aegypti and albopictus, they have not been completely eradicated in the country, and their proliferation has only increased in the Northeast region. Within the structure of the virus, it is possible to verify the presence of glycoprotein SN1, which is responsible for its replication. If this macromolecule is inhibited using a specific or complex linker, it can interrupt its replication activity. An alternative to this problem has been using structures derived from natural products that have pharmacological properties. A dynamic and molecular docking combined study used computational simulation in the four isomeric forms of bixin against the SN1 protein. The Z,E-bixin and E,E-bixin isomers, both with affinity energy -6.7 and -6.5 Kcal/mol, presented the best results. Thus, bixin and its isomers, found in annatto seeds, maybe an initial proposal in the search for prototype compounds to study to fight this lethal virus in the future.Communicated by Ramaswamy H.

Environmentally friendly achiote seed extracts with higher δ-tocotrienol content have higher in vitro and in vivo antioxidant activity than the conventional extract. JOURNAL OF FOOD SCIENCE AND TECHNOLOGY 2021; 58:2579-2588.

Abstract
Achiote (Bixa orellana) is highly appreciated as a condiment and as the main source of bixin and tocotrienols, both having antioxidant properties. To explore the possibility of maximizing the antioxidant activity of achiote seed extracts using clean methodologies, the use of sonication and green solvents were tested. Ethyl lactate, isopropyl acetate, and ethanol combined with probe sonication produced the best results, obtaining similar bixin contents but higher δ-tocotrienol contents, as well as significantly higher in vitro and in vivo antioxidant activity compared with the maceration method extract, requiring low energy and saving time and solvents. The probe-sonicated achiote extract with the highest δ-tocotrienol content was better at increasing the Caenorhabditis elegans resistance to oxidative stress than the extract obtained through maceration. This is the first report about the effect of sonication combined with green solvents on the bixin and δ-tocotrienol content in achiote seed extracts and its relevance on the in vitro and in vivo antioxidant activity.

Abstract
The main objective of this work was to evaluate the potential of Montmorillonite nanoclay (Mt), readily and inexpensively available, for the simultaneous adsorption (and removal) of two classes of pollutants: metal ions and dyes. The attention was focused on two "model" pollutants: Ce(III) and crystal violet (CV). The choice is due to the fact that they are widespread in wastewaters of various origins. These characteristics, together with their effect on human health, make them ideal for studies on water remediation. Moreover, when separated from wastewater, they can be recycled individually in industrial production with no or simple treatment. Clay/pollutant hybrids were prepared under different pH conditions and characterized through the construction of the adsorption isotherms and powder X-ray diffraction. The adsorption behavior of the two contaminants was revealed to be significantly different: the Langmuir model reproduces the adsorption isotherm of Ce(III) better, thus indicating that the clay offers a unique adsorption site to the metal ions, while the Freundlich model proved to be the most reliable for the uptake of CV which implies heterogeneity of adsorption sites. Moreover, metal ions do not adsorb at all under acidic conditions, whereas the dye is able to adsorb under all the investigated conditions. The possibility to modulate the adsorption features by simply changing the pH conditions was successfully employed to develop an efficient protocol for the removal and separation of the different components from aqueous solutions mimicking wastewaters.

Abstract
Genetic transformation allows for greater bixin or norbixin production in achiote. Knowledge of genes that control the biosynthesis of these important secondary metabolites will allow for targeted amplification in transgenic plants. Annatto is a natural dye or coloring agent derived from the seeds, or their arils, of achiote (Bixa orellana L.), and is commercially known as E160b. The main active component of annatto dye is water-insoluble bixin, although water-soluble norbixin also has commercial applications. Relative to other antioxidants, bixin is light- and temperature stable and is thus safe for human consumption. Bixin is, therefore, widely applied as a dye and as an antioxidant in the medico-pharmaceutical, food, cosmetic, and dye industries. Even though bixin has also been isolated from leaves and bark, yield is lower than from seeds. More biotechnology-based research of this industrial and medicinal plant is needed. Building on provisional genetic transformation studies, it would be advantageous to transform genes that could result in greater bixin or norbixin production. Reliable protocols for the extraction of bixin and norbixin, as well as deeper knowledge of the genes that control the biosynthesis of these important secondary metabolites will allow for targeted amplification in transgenic plants.
