NAD+‒circadian rhythm coupling in dementia

Alzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract The circadian rhythm system and sleep coordinate whole‐body functions across the 24‐h cycle, yet these rhythms progressively deteriorate with neurodegenerative diseases, including dementia. Growing evidence indicates that nicotinamide adenine dinucleotide (NAD+) interacts with the circadian system through multiple molecular pathways and that ...

Quantitative Real‐Time MRI for the Assessment of Gastric Motility

Journal of Magnetic Resonance Imaging, Volume 63, Issue 5, Page 1482-1495, May 2026.
ABSTRACT Background Current reference standards for measuring gastric emptying and motility are not considered optimal due to the time required, ionizing radiation, invasiveness, and spatial resolution. Purpose To assess gastric motility using novel real‐time dynamic magnetic resonance imaging in combination with static measurements for gastric ...

Survey of ST-Segment Changes due to Active Lead Fixation during Permanent Pacemaker Device Implantation as a Prognostic Indicator of its Performance

مجله دانشکده پزشکی اصفهان, 2017
Background: Active lead implantation can create injury in myocardium that may be associated with a ST-segment elevation. This ST-segment elevation may be correlated with changes in other parameters such as threshold, sense, amplitude, impedance, and ...

Analysis of Pulsatile Vessel Expansion in Healthy, COPD‐ and PH‐Patients Using Dynamic Vessel Segmentation in Free‐Breathing Lung MRI

Journal of Magnetic Resonance Imaging, Volume 63, Issue 5, Page 1420-1432, May 2026.
ABSTRACT Background The pulsatile expansion of pulmonary vessels carries dynamic cardiopulmonary information that may reveal disease earlier than structural changes alone. Purpose To test (i) intra‐ and inter‐scan repeatability of dynamic vessel metrics in healthy subjects, and (ii) whether chronic obstructive pulmonary disease (COPD) and postcapillary

Prehospital Risk Stratification Using Unsupervised Machine Learning in STEMI

European Journal of Clinical Investigation, Volume 56, Issue 5, May 2026.
Machine learning identified three phenotypes with 30‐day mortality of 3.4%, 22.1%, and 75%. Phenotype‐2 reveals an "occult high‐risk" group: hemodynamically stable yet six‐fold higher mortality. ABSTRACT Background ST‐elevation myocardial infarction (STEMI) exhibits substantial clinical heterogeneity complicating prehospital risk stratification ...

Are physiological oscillations physiological?

The Journal of Physiology, Volume 604, Issue 9, Page 3672-3693, 1 May 2026.
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Light as a chronobiologic countermeasure for long-duration space operations [PDF]

Long-duration space missions require adaptation to work-rest schedules which are substantially shifted with respect to earth. Astronauts are expected to work in two-shift operations and the environmental synchronizers (zeitgebers) in a spacecraft differ ...
