The central benefit of physiologically induced ketogenic states

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This review describes the association between ketogenic states induced by physiological interventions such as fasting or aerobic exercise, exogenous ketone supply and ketogenic diets, as well as increased cognition through increased activity of brain‐derived neurotrophic factor (BDNF).

Stable Nitrogen Isotope Analysis of Amino Acids by Orbitrap Mass Spectrometry: Application for Extraterrestrial Samples

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 23, 15 December 2025.
ABSTRACT Background Obtaining isotopic data on soluble organic compounds, such as amino acids, in extraterrestrial samples is crucial for understanding their origins, prebiotic chemistry, and potential contamination. Conventional GC‐IRMS requires grams of material to measure isotopic compositions, limiting the analysis of low‐concentration organics in ...

Fourier‐transform mid‐infrared spectroscopy for high‐throughput phenotyping of total dietary fiber in pulse crops

open access: yesThe Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract This study uses Fourier‐transform mid‐infrared (FT‐MIR) spectroscopy as a high‐throughput phenotyping tool to quantify total dietary fiber (TDF) in chickpea (Cicer arietinum L.), dry pea (Pisum sativum L.), and lentil (Lens culinaris Medik.) for pulse crop breeding purposes.

Rethinking “Prebiotic Chemistry”

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract In origins‐of‐life research, the term “prebiotic chemistry” is commonly used to describe processes thought to be related to or required for the emergence of life. However, it suffers from several potential drawbacks that have caused the present group of authors to rethink their usage of the term.

Upcycling Eggshell Matrix for Sustainable Production of Glycosaminoglycans

open access: yesBiopolymers, Volume 116, Issue 5, September 2025.
An Overview of Glycosaminoglycans Recovery Techniques and Their Diverse Applications. ABSTRACT Glycosaminoglycans (GAGs) are biomolecules with applications in the pharmaceutical, cosmetic, and nutraceutical industries. However, traditional GAG sources, such as animal tissues and marine organisms, present imminent challenges, including structural ...
