Beta‐casein in human milk is associated with infant stool frequency: A pilot proteomics study

Physiological Reports, Volume 14, Issue 15, August 2026.
Abstract Breast milk proteins may regulate gut function and defecation frequency; however, their specific roles in these processes remain poorly understood. We hypothesized that variations in specific human milk proteins are associated with differences in stool frequency among exclusively breastfed infants.

Amino acid homeostasis in the kidney: Physiological roles and pathological dysregulation

Physiological Reports, Volume 14, Issue 15, August 2026.
Abstract Amino acids are fundamental to life as protein building blocks and key regulators of metabolism and signaling. The kidney plays a critical, yet underappreciated, role in amino acid homeostasis through three interconnected pillars: selective glomerular filtration, efficient tubular reabsorption, and metabolic processing, which includes de novo ...

Melatonin as a protector against endocrine disruption across tissues: A systematic review

Physiological Reports, Volume 14, Issue 15, August 2026.
Graphical Abstract showing the biological mechanisms by which melatonin protects tissues against endocrine disruption. Abstract Endocrine‐disrupting chemicals (EDCs) are widespread environmental pollutants that interfere with hormonal homeostasis and contribute to multisystem toxicity.

Psychobiotics and the microbiota–gut–brain axis: Emerging paradigms in mental health modulation

Experimental Physiology, Volume 111, Issue 5, Page 2449-2463, 1 May 2026.
Abstract The global rise in mental health conditions has prompted interest in interventions that act beyond conventional psychopharmacology. Psychobiotics, broadly understood as live microorganisms or microbe‐derived products that interact with the microbiota–gut–brain axis, have been suggested to exert neuroactive effects through neural, immune ...

Adipocyte‐specific FFA2 deletion leads to increased adipose inflammation and is associated with altered intestinal lipid handling in mice

Physiological Reports, Volume 14, Issue 9, May 2026.
Abstract Obesity and related metabolic disorders are often characterized by chronic adipose tissue inflammation, driving systemic insulin resistance and general metabolic dysfunction. Free Fatty Acid Receptor 2 (FFA2) has emerged as a potential modulator of adipocyte function, inflammation, and metabolism.

Changes in metabolic risk factors and gut microbiota during weight gain in male first‐year college athletes

Physiological Reports, Volume 14, Issue 9, May 2026.
Abstract Many contact sport athletes have high body mass index (BMI) and high metabolic disease risk. Rapid weight gain in first‐year athletes may further increase this risk and affect gastrointestinal status. This study examined metabolic risk factor and gut microbiota during weight gain in 21 first‐year male college athletes.
