Synthetic Food Colorants and Gut Microbiota: A Systematic Review of Preclinical Studies

Food Frontiers, Volume 7, Issue 5, September 2026.
ABSTRACT Growing evidence suggests that industrial food processing, including the excess consumption of food additives, might have a negative impact on human health. Despite regulatory safety evaluations, their impact on gut microbiota remains poorly characterized.

Impacts of M. oleifera Leaf Extract on Weight Loss, the Metabolomic Profile, and the Intestinal Microbiota in Individuals With Simple Obesity

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
A total of 63 subjects participated in the formal trial, randomly assigned to either the control group (n = 29) or the intervention group (n = 34). The trial period lasted 90 days, during which the intervention group consumed Moringa oleifera leaf extract while the control group received a corresponding placebo.

Impact of Inoculation Strategy on Dendrobium nobile Lindl. Rice Wine Quality Through the Use of Saccharomyces cerevisiae FBKL2.8022 and Wickerhamomyces anomalus FBKL2.8023

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
This graphical abstract compares four fermentation strategies for D. nobile rice wine: simultaneous inoculation without D. nobile (SW), simultaneous inoculation with D. nobile (DnSW), sequential inoculation without D. nobile (WS), and sequential inoculation with D. nobile (DnWS). Simultaneous inoculation (SW/DnSW) enhanced volatile compound content (up

Overgrazing‐Induced Root Carbohydrate Depletion During Winter Dormancy Drives the Decline of Stipa purpurea Populations in the Tibetan Alpine Steppe

Land Degradation &Development, Volume 37, Issue 15, Page 11516-11532, September 2026.
ABSTRACT Plant carbon allocation and physiology are influenced by overgrazing during the growth period. However, the response of plant physiological processes to overgrazing during winter dormancy remains unclear. We analyzed root physiological processes of Stipa purpurea in winter dormancy across three plots: over grazing (FG), exclusions of 2 years ...

Siamyl Glyoxylate as an Efficient Enophile in the Lewis Acid Mediated Glyoxylate Ene-Reaction with Allylic Ethers. Application to the Synthesis of a Taxol A-Ring Subunit

, 2016
In contrast to other simple alkyl glyoxylates, siamyl glyoxylate (1a) proved to be an effective enophile in the glyoxylate ene-reaction with the allylic ether 2a, which we earlier used for the synthesis of the A-ring subunit of ...

Silyl Glyoxylates as a New Class of High Performance Photoinitiators: Blue LED Induced Polymerization of Methacrylates in Thin and Thick Films

, 2017
International audienceSilyl glyoxylates are proposed here as a new class of high performance type I photoinitiators for free radical polymerization under air or in laminate (e.g., (meth)acrylates) upon exposure to different near-UV (at 395 ma; at 405 nm)

Disruption of starch biosynthesis and triacylglycerol degradation impairs growth but improves photosynthesis in Arabidopsis

New Phytologist, Volume 251, Issue 6, Page 3472-3488, September 2026.
Proposed model for altered carbon partitioning in wild‐type (a) and tgd1 sdp1 adg1‐1 Arabidopsis triple mutant (b). Summary Enhancing lipid accumulation by redirecting carbon from starch to triacylglycerol (TAG) in vegetative tissues is a promising strategy for developing high‐energy‐density crops for bioenergy production. However, our understanding of

Tandem Kinase WTK1 Triggers Waves of Transcriptional Reprogramming Underlying Wheat Resistance to Stripe Rust

Physiologia Plantarum, Volume 178, Issue 5, September/October 2026.
ABSTRACT Tandem kinases are emerging regulators of plant immunity, but the downstream defense programs they activate remain poorly understood. Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a major constraint on global wheat production. The Yr15 resistance gene, derived from wild emmer wheat, encodes the tandem kinase protein WTK1.
