Optical and AFM microscopy of grape juices treated with UHPH: Effects of microstructure and nanostructure

BIO Web of Conferences, 2023
UHPH treatment of Vitis vinifera must for winemaking leads to fragmentation of colloidal particles into smaller structures. The shear and fracture forces experienced by grape juice during valve pressurization are sufficient to reduce the particle size of

Dose-dependent effects of selenium (Se)-enriched yeast containing nano-scale Se particles on Se bioavailability, rumen fermentation, hematological profile, and growth performance in female Thin-Tail sheep [PDF]

Veterinary World
Background and Aim: Selenium (Se) deficiency remains a significant nutritional challenge in sheep production due to the limited bioavailability of inorganic Se sources and the low Se availability in many soils and forages.

A 20S particle ubiquitous from yeast to human

Journal of Molecular Evolution, 1987
We have purified and characterized a particle sedimenting at 20S from the postribosomal fraction of yeast, wheat germ, Drosophila melanogaster tissue culture cells, chicken embryo fibroblasts, rabbit reticulocyte lysate, and HeLa cells. Most of the protein constituents of the 20S particle have molecular weights of 20-35 kd and differ between species ...

Microencapsulation of Baker’s Yeast in Gellan Gum Beads Used in Repeated Cycles of Glucose Fermentation

International Journal of Polymer Science, 2017
The purpose of this work is to prepare ionically cross-linked (with CaCl2) gellan particles with immobilized yeast cells for their use in repeated fermentation cycles of glucose. The study investigates the influence of ionic cross-linker concentration on

Biochemical and physiological studies of the yeast virus-like particle [PDF]

Journal of Bacteriology, 1977
A study was made of the virus-like particle (VLP) of Saccharomyces cerevisiae S7. This strain contains elevated amounts of P1 double-stranded ribonucleic acid (dsRNA) but no P2 dsRNA. The amount of dsRNA contained in cells grown on a fermentable carbon source (glucose) was compared with that in cells grown on a nonfermentable carbon source (ethanol ...

Yeast Particle Encapsulation of Azole Fungicides for Enhanced Treatment of Azole-Resistant Candida albicans

Journal of Functional Biomaterials
Addressing the growing problem of antifungal resistance in medicine and agriculture requires the development of new drugs and strategies to preserve the efficacy of existing fungicides. One approach is to utilize delivery technologies.

Implications of the Actin Cytoskeleton on the Multi-Step Process of [PSI⁺] Prion Formation

Viruses, 2022
Yeast prions are self-perpetuating misfolded proteins that are infectious. In yeast, [PSI+] is the prion form of the Sup35 protein. While the study of [PSI+] has revealed important cellular mechanisms that contribute to prion propagation, the underlying ...

The physical dimensions of amyloid aggregates control their infective potential as prion particles

eLife, 2017
Transmissible amyloid particles called prions are associated with infectious prion diseases in mammals and inherited phenotypes in yeast. All amyloid aggregates can give rise to potentially infectious seeds that accelerate their growth.

The comparison of genetic instability in haploid and diploid yeast cells exposed to ionizing radiations of different linear energy transfer and ultraviolet light

Journal of Radiation and Cancer Research, 2018
Context: It is analyzed whether genetic instability is determined by cell ability to recover from radiation damage or it is mainly determined by cell ploidy.
