Prospects in the Use of Extracts in Nanoemulsions.

plants have been widely investigated for their specific compounds with medicinal properties. These bioactive compounds exert preventive and curative effects on non-communicable and infectious diseases. However, extracts have barely been investigated, although they constitute an affordable option to treat human diseases.

Effect of diets containing probiotic yeast Cystobasidium benthicum and fruit Cyrtocarpa edulis on growth and immune parameters of Nile tilapia (Oreochromisniloticus).

This study investigates Cystobasidium benthicum (Cb) probiotic yeast and Cyrtocarpa edulis (Ce) fruit dietary effects, single (0.5 %) or combined (Cb:Ce, 0.25:0.

DyMnO: Synthesis, Characterization and Evaluation of Its Photocatalytic Activity in the Visible Spectrum.

DyMnO is a p-type semiconductor oxide with two crystal systems, orthorhombic and hexagonal. This material highlights its ferroelectric and ferromagnetic properties, which have been the subject of numerous studies. Nevertheless, its photocatalytic activity has been less explored.

Tannic acid-layered hydroxide salt hybrid: assessment of antibiofilm formation and foodborne pathogen growth inhibition.

Pathogenic bacteria in food are a public health problem worldwide. Polyphenolic bioactive compounds with antimicrobial activity and antioxidant capacity represent a tangible alternative to overcome this problem. To preserve the biological functions of phenolic compounds such as tannic acid, which has been described to possess antioxidant and antimicrobial activity, this study describes the synthesis of a zinc nanohydroxide to stabilize its properties.

Development, characterization, and immunomodulation performance of spray-dried Moringa oleifera seed extract in Longfin yellowtail Seriola rivoliana.

Moringa oleifera is one of the most promising plants in aquaculture because it improves the health status, zootechnical parameters and resistance against diseases. This research evaluates the physicochemical, antioxidant values of spray-dried Moringa oleifera seed extract microencapsulates obtained at 140 and 180 °C with whey protein concentrate (WPC) and maltodextrin (MD) as wall materials in two different proportions: WPC 100% and WPC-MD (3:1). Also, immune response of peripheral blood leukocytes (PBL) of Longfin yellowtail Seriola rivoliana stimulated with spray-dried Moringa oleifera seed for 24 h was assessed.

Determining the Photoelectrical Behavior and Photocatalytic Activity of an h-YMnO New Type of Obelisk-like Perovskite in the Degradation of Malachite Green Dye.

YMnO is a P-type semiconductor with a perovskite-type structure (ABO). It presents two crystalline systems: rhombohedral and hexagonal, the latter being the most stable and studied. In the hexagonal system, Mn ions are coordinated by five oxygen ions forming a trigonal bipyramid, and the Y ions are coordinated by five oxygen ions.

[Assessment of the in vitro effect of intra and extracellular extracts of Lactobacillus against genotoxicity and oxidative stress caused by acrylamide].

Introduction: acrylamide is formed by the Maillard reaction and is found in many food products subjected to thermal processes, generating genotoxicity and DNA damage. Studies have reported that lactobacilli have the ability to generate compounds with antioxidant, antigenotoxic and antimutagenic activity, which is why the present work aims to evaluate the effect of Lactobacillus strains and their intra and extracellular extracts against genotoxicity and oxidative stress as caused by acrylamide. Methods: a strain of Lactobacillus casei Shirota and a strain of Lactobacillus reuteri NRRL B-14171 were used, both were cultured in MRS broth and subjected to mechanical and enzymatic treatments to obtain extra and intracellular extracts.

Human lactoferrin from breast milk: characterization by HPLC and its in vitro antibiofilm performance.

Preterm infants are at high risk of infection due to opportunistic bacteria as , causing infections among infants in neonatal intensive care units. Human lactoferrin (hLf) is a multifunctional protein and one of the most abundant in breast milk, and plays an important role in prevention of different infections in neonates. This work offers a strategy to obtain a lyophilisate of purified lactoferrin from breast milk.

Nanohybrid of Thymol and 2D Simonkolleite Enhances Inhibition of Bacterial Growth, Biofilm Formation, and Free Radicals.

Due to the current concerns against opportunistic pathogens and the challenge of antimicrobial resistance worldwide, alternatives to control pathogen growth are required. In this sense, this work offers a new nanohybrid composed of zinc-layered hydroxide salt (Simonkolleite) and thymol for preventing bacterial growth. Materials were characterized with XRD diffraction, FTIR and UV-Vis spectra, SEM microscopy, and dynamic light scattering.

Chemical and biological protection of food grade nisin through their partial intercalation in laminar hydroxide salts.

The use of antimicrobial agents within a matrix, specifically layered compounds, is of growing interest for reducing contamination due to food borne pathogens and deteriorative microorganisms, one of the main health problems worldwide. In this study, zinc layered hydroxide nanoparticles were synthesized as a matrix for nisin immobilization. Layered materials were characterized by X-ray diffraction, Fourier-Transform Infrared and Ultra Violet-Visible spectra, Scanning Electron Microscopy, and by Thermogravimetric Analysis.
