Does human evolution in different latitudes influence susceptibility to obesity via the circadian pacemaker?

, 2012
The variable photoperiods of Northern latitudes challenge the entrainment capacity of the circadian pacemaker, which evolved under constant photoperiods in Equatorial regions.

Multitarget Drug Design for Cardiovascular Disease: Bridging Chemistry and Medicine

ChemMedChem, Volume 21, Issue 19, 14 October 2026.
Many pathophysiological pathways associated with cardiovascular diseases involve multiple drug targets. This article reviews recent advances in the development of pharmacological compounds capable of simultaneously modulating multiple mechanisms. Multitarget drugs offer a promising therapeutic approach for complex cardiovascular disorders, including ...

Cortisol Dynamics at High Temporal Resolution For Wearable Biosensor Research

Advanced Sensor Research, Volume 5, Issue 10, October 2026.
High‐frequency cortisol profiling reveals that endocrine responses depend strongly on both stressor type and the individual. Circadian sampling shows a consistent morning‐to‐evening decline, while cold exposure elicits delayed rises and exercise and cognitive challenges produce divergent trajectories.

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 ...

A Dual‐Modal Wearable PPG Smartwatch with AI‐Enhanced Correction for High‐Accuracy and Continuous AF Burden Assessment

Advanced Science, Volume 13, Issue 56, 9 October 2026.
ABSTRACT Atrial fibrillation (AF) increases the risk of stroke and heart failure, yet accurate quantification of AF burden in daily life remains difficult. Although smartwatch photoplethysmography (PPG) supports continuous monitoring, complex rhythms and signal noise can impair burden estimation.

Explorations into development of a neurally regulated cardiac pacemaker

, 1995
Although the artificial cardiac pacemaker has contributed to the management of patients with serious arrhythmias, its rate-responsive function is not sufficient to provide physiological regulation of heart rate (HR).

Repetitive Transcranial Magnetic Stimulation Combined With Median Nerve Electrical Stimulation for Severe Traumatic Brain Injury

Brain and Behavior, Volume 16, Issue 10, October 2026.
Combining top‐down rTMS over the left DLPFC with bottom‐up right median nerve stimulation markedly outperformed either modality alone, awakening 93% of patients with severe TBI by week 4 and improving EEG, hemodynamics, and GCS—supporting dual‐pathway neuromodulation as a safe, high‐efficacy strategy for coma recovery.

Study of the control system of a pacemaker for the heart rate regulation

reservedI pacemaker sono dei dispositivi elettro-medicali che emettono degli impulsi elettrici con lo scopo di ristabilire il normale ritmo cardiaco per garantire ai tessuti la corretta erogazione di ossigeno.
