Biochemical Responses of Anopheles spp. Larvae to a Novel Brazilian BR101 Bacillus thuringiensis var. israelensis Formulation: Oxidative Stress, Detoxification Enzymes, and Safety for Nontarget Notonectidae and Gerridae Aquatic Insects

Chemistry &Biodiversity, EarlyView.
Bti BR101 exhibits strong larvicidal activity against Anopheles larvae spp., with dose‐dependent mortality and LC50 of 3.13 µg/mL. Bti increases ROS, lipid and protein oxidation, and activates antioxidant enzymes (SOD, CAT, GPx) and detoxification pathways (MFO and esterases), indicating moderate oxidative stress.

In Silico Design and Validation of a Novel HPPD‐Inhibiting Herbicide Candidate Based on Benzofuran and Arylthioacetic Acid Scaffolds

Chemistry &Biodiversity, EarlyView.
A benzofuran‐triketone hybrid emerged as the most promising 4‐hydroxyphenylpyruvate inhibitor, showing the highest predicted activity and strongest binding compared to the best experimental compound. Free computational tools guided candidate selection, predicted interactions with the enzyme, and confirmed stable binding.

From Molecule to Meaning: Click and Bioorthogonal Chemical Reporters for Plant Systems, Biological Imaging, and Artistic Expression

ChemBioChem, EarlyView.
At the intersection of chemical biology, plant imaging, and contemporary art, this review introduces the concept of chembioart. By tracing how chemical reporters illuminate plant biomolecules in vivo, their role not only in advancing scientific understanding but also in inspiring transdisciplinary collaborations and visual expression is highlighted ...

UHPLC‐MSE Insights Into Extrusion‐Driven Changes in Wheat Phenolics and Their Bioaccessibility

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives This study evaluated the impact of thermoplastic extrusion (wheat snack, WS) and cold extrusion followed by cooking (wheat pasta, WP) on phenolic compounds (PC) in two Brazilian wheat genotypes, commercially classified by gluten strength (ORS Agile, strong; ORS Vintecinco, weak).

Gut flora in health and disease

The Lancet, 2003
The human gut is the natural habitat for a large and dynamic bacterial community, but a substantial part of these bacterial populations are still to be described. However, the relevance and effect of resident bacteria on a host's physiology and pathology has been well documented.

Overview of gut flora and probiotics

International Journal of Food Microbiology, 1998
Scientific developments in recent years have opened new frontiers and enable a better understanding of the gastrointestinal tract (GIT) as a complex and delicately balanced ecosystem. This paper focuses on more recent information related to the microbial population of the GIT and its functional role in human physiology and health.

The metabolism of drugs by the gut flora

European Journal of Drug Metabolism and Pharmacokinetics, 1994
Gut flora and gut contents can be considered as a system with huge metabolic capacity, qualitatively and quantitatively different from the body cells and organs. That system changes along with life and nutrition, but despite broad investigation has not yet been defined satisfactorily.

THE GUT FLORA OF THE CHICK. II. THE ESTABLISHMENT OF THE FLORA

Journal of Applied Bacteriology, 1956
SUMMARY: Viable counts were made in three media of material from the crop, gizzard, duodenum, ileum and caeca of chicks. Groups of birds 2, 4, 7, 10, 13, 16 and 30 days old were studied. The results showed that a balanced gut flora is established one day after feeding.
