Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

Integrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Influence of Fermentation and Curing on Residual Nitrite, Physico‐Chemical, Volatile, Sensory, and Microbiological Properties of Sucuk Döner Kebab During Refrigerated and Frozen Storage

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
The effects of fermentation with and without nitrite on the physicochemical properties, lipid oxidation, volatile compounds, sensory characteristics, and overall quality of ready‐to‐eat sucuk döner kebabs were evaluated, demonstrating that fermentation, particularly without nitrite, improved oxidative stability and sensory quality. ABSTRACT The present

Hyperhomocysteinemia, Suppressed Immunity, and Altered Oxidative Metabolism Caused by Pathogenic Microbes in Atherosclerosis and Dementia

Frontiers in Aging Neuroscience, 2017
Many pathogenic microorganisms have been demonstrated in atherosclerotic plaques and in cerebral plaques in dementia. Hyperhomocysteinemia, which is a risk factor for atherosclerosis and dementia, is caused by dysregulation of methionine metabolism ...

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, Volume 32, Issue 26, 11 July 2026.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Iminodirhodium‐ and Iminocopper‐Catalyzed CH Activation: Chemoselective Oxidation of Alcohols and Aldehydes via Intermolecular Hydride Abstraction

European Journal of Organic Chemistry, Volume 29, Issue 25, 4 July 2026.
Chemoselective hydride abstractor iminometalloids, derived from O‐mesylacetoxime (MAO) using Rh2(II/II) or Cu(I) catalysts, can activate the C–Hα bonds of alcohols and aldehydes ultimately forming ketones, carboxylic acids, and esters even in the presence of C–H bonds with comparable bond strengths.

Differentiation of mouth versus gut as site of origin of odoriferous breath gases after garlic ingestion [PDF]

, 1999
Utilizing the sulfur-containing gases of garlic as probes, we investigated the gut versus mouth origin of odoriferous breath gases. Five individuals ingested 6 g of garlic, and sulfur gases in mouth, alveolar air, and urine samples were measured.

Deodorising Garlic Body Odour by Ingesting Natural Food Additives Containing Phenolic Compounds and Polyphenol Oxidase

Applied Sciences
Garlic consumption is a well-known cause of unpleasant breath and body odour, with volatile organosulfur compounds, such as diallyl disulfide (DADS) and allyl methyl sulfide (AMS) responsible for the characteristic odour.
