A global estimator of C and N isotope baselines for fresh waters

Methods in Ecology and Evolution, EarlyView.
Abstract Baselines are the pebbles in the shoes of isotope ecologists. The extreme variability of the isotope composition of resources at the base of food webs governs the spatial differences of consumers' isotope composition, so that isotope‐inferred trophic properties can be compared across ecosystems only after correction for baseline effects ...

Fats, Fire and Bronze Age Funerary Rites: Organic Residue Analysis of Wide Horizontal Rim Vessels From Burial Contexts in Northwest Portugal

Archaeometry, EarlyView.
ABSTRACT This study presents the first GC‐MS–based analyses of wide horizontal rim vessels with well‐defined funerary contexts, from Middle Bronze Age Portugal (Quinta do Amorim 2 and Pego). Organic residues from two vessels revealed ruminant fats and plant oils, alongside molecular markers of heat exposure.

Fecal Steroids as Tracers of Human Population and Waste Management Practices at the Ancient Maya City of Ucanal, Guatemala

Archaeometry, EarlyView.
ABSTRACT Geochemical data compiled from dried sediments from three water reservoirs at the ancient Maya city of Ucanal, Petén, Guatemala, reveal low to undetectable fecal biomarker concentrations. These low concentrations may be the result of the aerobic decay of sterols combined with well‐managed waste disposal practices.

The return of metabolism: biochemistry and physiology of glycolysis

Biological Reviews, EarlyView.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Changes in gastrointestinal motility and gut hormone secretion after Roux‐en‐Y gastric bypass and sleeve gastrectomy for individuals with severe obesity

Clinical Obesity, Volume 15, Issue 2, April 2025.
Summary Background Bariatric surgery is very effective in long‐term weight management. The present study was undertaken to investigate the short‐term effects of sleeve gastrectomy (SG) and of Roux‐en‐Y gastric bypass (RYGB) on (a) gastrointestinal (GI) motility, that is gastric emptying and oro‐cecal transit time and (b) secretion of regulatory gut ...
