Stand-Alone Heartbeat Detection in Multidimensional Mechanocardiograms

open access: yesIEEE Sensors Journal, 2019
We describe a home health monitoring solution with cardiac beat-to-beat detection using accelerometer and gyroscope signal fusion. The proposed method measures both the precordial translational and rotational motions of the chest using miniaturized inertial sensors.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Leave-one-out prediction error of systolic arterial pressure time series under paced breathing [PDF]

open access: yes, 2004
In this paper we show that different physiological states and pathological conditions may be characterized in terms of predictability of time series signals from the underlying biological system.

Novel implantation of vagus nerve stimulator AspireSR pulse generator: Technical note

open access: yesInterdisciplinary Neurosurgery, 2017
Objective: To eliminate the need for preoperative evaluation required for the Aspire SR pulse generator and allow for minimum sensitivity settings, thereby providing the most accurate setting for cardiac-based seizure detection (CBSD).

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Interplay between heartbeat oscillations and wind outflow in microquasar IGR J17091-3624 [PDF]

open access: yes, 2015
During the bright outburst in 2011, the black hole candidate IGR J17091-3624 exhibited strong quasi-periodic flare-like events (on timescales of tens of seconds) in some characteristic states, the so-called heartbeat state.

Non-Contact Detection of Vital Signs Using a UWB Radar Sensor

open access: yesIEEE Access, 2019
The ultra-wide band (UWB) radar sensor is useful in the field of mission critical sensors and sensor networks due to its short detection time, high penetration, and low energy consumption.

Optimized Solutions of Electrocardiogram Lead and Segment Selection for Cardiovascular Disease Diagnostics

open access: yesBioengineering, 2023
Most of the existing multi-lead electrocardiogram (ECG) detection methods are based on all 12 leads, which undoubtedly results in a large amount of calculation and is not suitable for the application in portable ECG detection systems.

X-ray spectral state evolution in IGR J17091-3624 and comparison of its heartbeat oscillation properties with those of GRS 1915+105

open access: yes, 2014
In this work, we study the X-ray timing and spectral evolution of the transient low mass X-ray binary IGR J17091-3624 during first 66 days of its 2011 outburst.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.
