Enzyme Detection and Metabolic Process Tracking of Ethanol Fermentation by a Natural Alginate Fermentation Strain

open access: yesBrazilian Archives of Biology and Technology, 2018
Alginate is a major component of brown algae, but it cannot be utilized for ethanol fermentation by industrial microorganisms. A natural alginate degrading and ethanol producing strain was obtained in our previous research.

Exploring vaginal microbiota–tissue resident stem cell crosstalk: VCAM1/Akt signaling ‐mediated enhancement of regenerative capacity

open access: yesInterdisciplinary Medicine, EarlyView.
Vaginal microbiota‐derived secretory factors enhance the regenerative capacity of human endometrial stem cells by upregulating VCAM1 and activating PI3K/Akt signaling. This microbiota–stem cell crosstalk promotes self‐renewal, migration, multilineage differentiation, and metabolic reprogramming in vitro and in vivo, establishing a novel microbiota ...

Shikonin Promotes Apoptosis in Multiple Myeloma Cells Through the PKM2‐AMPK‐PGC1α Metabolic Axis

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
High PKM2 expression in MM is associated with a poor prognosis. Shikonin represents a promising PKM2‐targeted agent for MM therapy, offering a unique metabolic intervention strategy to improve drug resistance, bone disease, and the immune microenvironment. ABSTRACT Background Multiple myeloma (MM) is an incurable plasma malignancy.

Identification of differential metabolites in liquid diet fermented with Bacillus subtilis using gas chromatography time of flight mass spectrometry

open access: yesAnimal Nutrition, 2016
Growth and health responses of pigs fed fermented liquid diet are not always consistent and causes for this issue are still not very clear. Metabolites produced at different fermentation time points should be one of the most important contributors ...

Effects of oat protein on hematological parameters and metabolism in Wistar rats

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Diets rich in plant‐based proteins are becoming increasingly popular, but the safety of extracted oat (Avena sativa L.) protein in relation to cardiometabolic and endocrine risks remains unexplored. This study evaluated the safety of oat protein by analyzing anthropometric, hematological, biochemical, and histopathological ...

Stimuli‐responsive nanostructured hydrogen sulfide donors for enhanced cancer treatments

open access: yesSmart Molecules, EarlyView.
Three typical kinds of stimuli‐responsive nanostructured hydrogen sulfide (H2S) donors are reviewed. The nanostructures ensure precise delivery of H2S to the lesion site and regulate the release behavior. The H2S‐based gas therapy has been used to synergize with other cancer treatment modalities, achieving enhanced efficacy while reducing side effects.
