Cu(A) is a binuclear electron transfer (ET) center found in cytochrome c oxidases (CcOs), nitrous oxide reductases (N₂ORs), and nitric oxide reductase (NOR). In these proteins, the Cu(A) centers facilitate efficient ET (kET > 10⁴s⁻¹) under low thermodynamic driving forces (10-90 mV). While the structure and functional properties of Cu(A) are well understood, a detailed mechanism of the incorporation of copper into the protein and the identity of the intermediates formed during the Cu(A) maturation process ...

The current work focuses on developing nanocomposite films using taro starch and cellulose nanofibers extracted from the root's peel. Films were prepared using mixtures of starch, cellulose nanofibers (0 %, 5 %, 10 %, and 15 % w/w), glycerol, and water. Results showed that the addition of cellulose nanofibers increased film thickness, opacity, UV-light barrier capacity, and water swelling percentage. All films showed a typical B-type X-ray diffraction pattern characteristic of semicrystalline materials. FTIR ...

Abstract Carbon quantum dots (CQDs) are a special type of nanostructure characterized for their low toxicity, environmentally friendliness, and ease of manufacture from varied carbon sources like carbohydrates. This carbon source is abundant in natural products and organic wastes, and it is suitable to be used in food applications like nano sensors for food quality and safety. Indeed, CQDs are foreseen as a potential new type of practical and unexpensive sensor to detect harmful substances commonly ...

Abstract Different architectures at a nanometric scale such as nanocrystals, nanofibers, nanomicelles, nanoparticles, and nanovesicles can be produced from native starches using “top‐down” and “bottom‐up” approaches. These starch nanomaterials (SNMts) have particle size lower than 1000 nm, exhibiting different physicochemical properties than those found in native starches. In recent years several studies have explored the applications of SNMts in the food sector. The production and food application ...

Moisture content, water activity, color, morphology, thermal behavior (differential scanning calorimetry), swelling factor, solubility in water, water sorption isotherms, rheological properties, and stability in water are analyzed and compared using native potato starch (PS) as control. The resulting SNPs after anti‐solvent precipitation have a particle ...

The aim of this research is to study the thermal degradation kinetics and some physicochemical properties of starch nanoparticles (SNPs) produced from potato starch (PS) by nanoprecipitation. Native PS is used as a control. The powder samples are analyzed by means of light and transmission electron microscopies, X‐ray diffraction, Fourier transform infrared, and thermogravimetric analysis. PS shows oval and spherical granular shaped with a diameter between 6 and 18 µm, whereas SNPs display spherical ...

Biopolymeric nanoparticles have better water solubility and stability when compared with unmodified biopolymers. This review article focuses on the analysis of the state of the art available in the last ten years about the production mechanism and biopolymer type, as well as the used of these nanomaterials to encapsulate biological compounds, and the potential applications of biopolymeric ...

Abstract Starch‐based coatings (SC) are materials used to extend the shelf life and preserve the quality of foods during storage. Several approaches such as panning, fluidized bed, dipping, and spraying can be used to apply SC on foods. In general, SC are produced using gelatinized starch in water, in the presence of plasticizers, however, mixtures of starches with other macromolecules such as carbohydrates, proteins, and lipids also have been investigated aiming to manufacture SC with improved physicochemical ...

Ciliogenesis and cystogenesis require the exocyst, a conserved eight-protein trafficking complex that traffics ciliary proteins. In culture, the small GTPase Cdc42 co-localizes with the exocyst at primary cilia and interacts with the exocyst component Sec10. The role of Cdc42 in vivo, however, is not well understood. Here, knockdown of cdc42 in zebrafish produced a phenotype similar to sec10 knockdown, including tail curvature, glomerular expansion, and mitogen-activated protein kinase (MAPK) activation, ...

Anthocyanins (ACNs) are natural compounds with potential applications due to their colorimetric response to pH. Due to their sensitivity to various environmental factors, nanoencapsulation with biopolymers is a successful strategy for stabilizing ACNs. In this work ACNs were extracted from grape skins and encapsulated into chitosan (CS) nanoparticles by ionic gelation using sodium tripolyphosphate (TPP) as a cross-linking agent. CS nanoparticles loaded with ACNs had particle sizes between 291 and 324 ...

Exercise recommendations for hypertensive individuals encourage the use of aerobic training (AT) for lowering blood pressure (BP). However, it is not clear whether equivalent BP-lowering effects are obtained with different exercise training types in older adults, among whom hypertension is more prevalent.

Abstract Starch is a natural carbohydrate that is commonly isolated from conventional sources such as corn, cassava, potato, wheat, and rice. However, in recent years new sources of starch have been studied, named as unconventional sources, usually from seeds and legumes, which have comparable properties to traditional starch sources. In recent years, new sources of starch from various seeds have been observed, including durian ( Durio zibethinus Murr.), jackfruit ( Artocarpus heterophyllus ), loquat ( Eriobothrya ...

Knowledge of the Earth’s atmospheric optical turbulence is critical for astronomical instrumentation. Not only does it enable performance verification and optimization of the existing systems, but it is required for the design of future instruments. As a minimum this includes integrated astro-atmospheric parameters such as seeing, coherence time, and isoplanatic angle, but for more sophisticated systems such as wide-field adaptive optics enabled instrumentation the vertical structure of the turbulence ...
