The circadian clock regulates the diurnal levels of microbial short‐chain fatty acids and their rhythmic effects on colon contractility in mice

Acta Physiologica, 2018
The microbiota shows diurnal oscillations that are synchronized by the host's circadian clock and feeding rhythms. Short‐chain fatty acids (SCFAs) produced by the microbiota are possible synchronizers of peripheral circadian clocks.

Hypothalamic Control of Liver Health and Disease: From Circuits to Pathophysiology and Therapies

Advanced Science, EarlyView.
This review delineates the hypothalamic circuits that control liver homeostasis via autonomic and neuroendocrine pathways. Dysregulation of this hypothalamus–liver axis drives disease progression across a spectrum including steatotic liver disease, liver inflammation and injury, fibrosis, cirrhosis, and hepatocellular carcinoma.

Soft, Multi‐Wavelength Photoplethysmography Enables Reliable Neonatal Blood Pressure Monitoring Via Error Stratification

Advanced Science, EarlyView.
A soft hybrid multi‐wavelength PPG wearable acquires neonatal signals. Synchronized PPG and invasive ABP data are segmented into fixed windows. A 1D‐EfficientNet model predicts segment‐level SBP and DBP. Model performance is examined with retrospective subgroup analysis across acquisition conditions.

Ahcy Acts as an Effector of Hnf4a‐Driven Super‐Enhancer Activation to Alleviate MASLD During Intermittent Fasting

Advanced Science, EarlyView.
Our study identifies an Hnf4a‐driven super‐enhancer of hepatic Ahcy that mediates the protective effects of intermittent fasting against MASLD. Disruption of the Ahcy super‐enhancer reduces Ahcy expression and exacerbates lipid accumulation. This pathway prevents aberrant promoter hypermethylation by maintaining the SAM/SAH balance, as exemplified by ...

The Risk of Cardiovascular Diseases for Shift Workers in the Prospective Heinz Nixdorf Recall Study

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Shift work can disrupt circadian rhythms and is postulated to play a role in cardiovascular diseases (CVD). In the German prospective population‐based Heinz Nixdorf Recall Study, we analyzed longitudinal associations between shift work and night‐shift work with CVD.

Melatonin Levels in 89 Individuals With Smith Magenis Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT In patients with Smith–Magenis syndrome (SMS), an inverted circadian rhythm of melatonin (MT) contributes to the sleep disturbance. Standard treatment of sleep disturbance with MT often leads to extremely high daytime MT levels, resulting in even more sleep disorders. We therefore retrospectively evaluated the MT data of 89 SMS patients.

Distinct Neuropsychiatric Profiles Associated With 17p11.2 Deletions and RAI1 Variants in Smith–Magenis Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Smith–Magenis syndrome (SMS) results from either a recurrent 17p11.2 deletion or pathogenic variants in the retinoic acid induced 1 gene (RAI1). While neurodevelopmental impairment and behavioral dysregulation are well recognized, systematic genotype‐stratified analyses across psychiatric domains remain limited.

Multipathway modulation of neuroinflammation and oxidative stress by hesperidin in a rat single prolonged stress model of post‐traumatic stress disorder

Animal Models and Experimental Medicine, EarlyView.
Single prolonged stress (SPS) induces post‐traumatic stress disorder (PTSD)‐like neuropathology characterized by oxidative stress, neuroinflammation, astrocytic reactivity, neuronal damage, and reduced neurotrophic support in the hippocampus, amygdala, and prefrontal cortex. Hesperidin counteracts these effects by attenuating lipid peroxidation and pro‐

Analysis of energy expenditure and behavioral characteristics in different mouse strains under normal and disease conditions

Animal Models and Experimental Medicine, EarlyView.
Mouse metabolic and behavioral phenotypes are tightly linked to strain, age and disease state, with distinct dysregulation in each disease model, underscoring the need for standardized preclinical experimental conditions. Abstract Background Metabolic and behavioral traits in mice exhibit substantial variability across strains, ages, and disease states,
