Acute intermittent hypercapnic hypoxia augments left ventricular contractility

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐four healthy adults were studied to determine the effects of an acute session of 40 min of intermittent hypercapnic hypoxia on cardiac performance. Cardiac function was assessed via echocardiography at rest and during graded stages of lower‐body negative pressure before and after the intervention to quantify load ...

Chronobiology and Chronotherapy of Osteoporosis

open access: yesJBMR Plus, 2021
Physiological circadian (ie, 24‐hour) rhythms are critical for bone health. Animal studies have shown that genes involved in the intrinsic molecular clock demonstrate potent circadian expression patterns in bone and that genetic disruption of these clock

Pinopsin Regulates Melatonin Production and Daily Locomotor Activity: Functional Insights From Gene‐Edited Xenopus Tadpoles

open access: yesJournal of Pineal Research, Volume 78, Issue 2, March 2026.
ABSTRACT Circadian rhythm alignment depends on environmental light detection via opsins. Pinopsin, originally identified in the pineal organ of birds and later in amphibian pineal complex and eyes, may play a role in this process, though its function has not been genetically tested.

Imaging Multidimensional Therapeutically Relevant Circadian Relationships

open access: yesInternational Journal of Biomedical Imaging, 2009
Circadian clocks gate cellular proliferation and, thereby, therapeutically target availability within proliferative pathways. This temporal coordination occurs within both cancerous and noncancerous proliferating tissues.

Effect of Selecting Cereal Leaf Beetle (Coleoptera: Chrysomelidae) Males by Age and Feeding Behavior on Nondiapause Progeny [PDF]

open access: yes, 2017
In a nondiapause culture of cereal leaf beetles, Oulema melanopus (Coleoptera: Chrysomelidae), females ovipositing within 20 days after emergence were considered nondiapause.

Heat Therapy: Targeting Health, Disease, and Disability

open access: yesComprehensive Physiology, Volume 16, Issue 1, February 2026.
The predominance of evidence suggests heat therapy has an impact on all aspects of health and performance, but the drivers of that improvement, the extent to which they are improved, and the specific populations in which improvements manifest are far from completely understood.

A Conserved Circadian Function for the Neurofibromatosis 1 Gene

open access: yesCell Reports, 2018
Summary: Loss of the Neurofibromatosis 1 (Nf1) protein, neurofibromin, in Drosophila disrupts circadian rhythms of locomotor activity without impairing central clock function, suggesting effects downstream of the clock.

Exploring the uncertain relationship between lunar phases and human sleep duration and quality: A narrative literature review​ [PDF]

open access: yes, 2020
The moon’s influence on human behavior has been the subject of speculation for a large portion of history. A whole host of physiological and psychological disorders were collectively explained away by lunacy or madness until the advent of modern science ...
