Potential health benefits of cold‐water immersion: the central role of PGC‐1α

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

Metabolic effects of l-thyroxine and l-triiodothyronine on the intact rat and selected excised tissues

open access: yes, 1959
Time-response curves for the oxygen consumption of the intact rat and excised tissues were determined after single equimolar injections of l-thyroxine or l-triiodothyronine.

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Reduced cardiovascular mortality at moderate altitude: a putative role of physical activity and body mass

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Benefits of performing physical exercise at moderate altitude. At moderate altitude, increased resting metabolic rate and physical exertion promote physical fitness and exercise tolerance, whereas hypoxia suppresses appetite and elicits adaptations that increase tissue O2 delivery while augmenting O2‐independent ATP production ...

Voltage‐gated potassium channels mediate thyroid hormone control of skeletal muscle excitability

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Thyroid hormone (TH)‐dependent remodelling of potassium (K+) channel networks regulates skeletal muscle (SkM) excitability. Triiodothyronine (T3), locally generated from thyroxine (T4) by type 2 deiodinase (D2), binds thyroid hormone receptors (TRα/β) and modulates transcription via thyroid response elements (TREs).

Psychotic depression associated with Graves' disease: A case report on treatment prioritization

open access: yesPsychiatry and Clinical Neurosciences Reports, Volume 5, Issue 4, December 2026.
Abstract Background Graves' disease can be accompanied by psychiatric symptoms, including affective and psychotic manifestations. When a well‐defined psychiatric syndrome occurs concurrently with a medical illness, determining whether it is directly attributable to the medical condition or represents an independent psychiatric disorder precipitated by ...

Film autoradiography identifies unique features of [125I]3,3'5'-(reverse) triiodothyronine transport from blood to brain

open access: yes, 1994
1. Steady-state iodothyronine profiles in plasma are composed of thyroid gland-synthesized hormones (mainly thyroxine) and tissue iodothyronine metabolites (mainly triiodothyronine and reverse triiodothyronine) that have entered the bloodstream.

Age‐Related Patterns of Relative Energy Deficiency in Sport (REDs) Symptoms and Key Performance Factors in Adolescent Biathletes

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 11, November 2026.
ABSTRACT Relative Energy Deficiency in Sport (REDs) impairs health and performance, but age‐related patterns in its emergence remain unclear. This study examines RED symptoms in adolescent biathletes at season‐start and their link to end‐of‐season performance.
