Platelet-to-White Blood Cell Ratio (PWR): A Novel Prognostic Biomarker for Spontaneous Reperfusion after Primary Percutaneous Coronary Intervention.

Background: Spontaneous reperfusion (SR) occurring before primary percutaneous coronary intervention (PPCI) can offer additional clinical benefits to patients with ST-segment elevation myocardial infarction (STEMI). The Platelet-to-White Blood Cell Ratio (PWR) has been recognized as a prognostic indicator in various diseases. We aimed to explore the relationship between PWR and SR in patients with STEMI undergoing PPCI.

Usability of myocardial work parameters in demonstrating myocardial involvement in INOCA patients.

Background: Myocardial work (MW) is a novel echocardiographic modality, which has been shown to have diagnostic and prognostic values in patients with cardiovascular diseases, patients with obstructive coronary artery disease, in particular. However, only a handful of studies have examined the MW analysis in ischemia with nonobstructive coronary artery (INOCA) disease. This study, therefore, aimed to detect the early left ventricular involvement in INOCA patients diagnosed by an invasive coronary angiography performing the MW analysis.

A Versatile 3D-Printable Soft Pneumatic Actuator Design for Multi-Functional Applications in Soft Robotics.

Experimental Evaluation of a Hybrid Sensory Feedback System for Haptic and Kinaesthetic Perception in Hand Prostheses.

This study proposes a new hybrid multi-modal sensory feedback system for prosthetic hands that can provide not only haptic and proprioceptive feedback but also facilitate object recognition without the aid of vision. Modality-matched haptic perception was provided using a mechanotactile feedback system that can proportionally apply the gripping force through the use of a force controller. A vibrotactile feedback system was also employed to distinguish four discrete grip positions of the prosthetic hand.

Edge-Functionalized Graphene/Polydimethylsiloxane Composite Films for Flexible Neural Cuff Electrodes.

The design of neural electrodes has changed in the past decade, driven mainly by the development of new materials that open the possibility of manufacturing electrodes with adaptable mechanical properties and promising electrical properties. In this paper, we report on the mechanical and electrochemical properties of a polydimethylsiloxane (PDMS) composite with edge-functionalized graphene (EFG) and demonstrate its potential for use in neural implants with the fabrication of a novel neural cuff electrode. We have shown that a 200 μm thick 1:1 EFG/PDMS composite film has a stretchability of up to 20%, a Young's modulus of 2.

Impact of HATCH Score on the Development of No-Reflow Phenomenon in Patients With ST-Segment Elevation Myocardial Infarction.

The HATCH score [Hypertension (1 point), Age > 75 years (1 point), Stroke/Transient ischemic attack (2 points), Chronic obstructive pulmonary disease (1 point), and Heart failure (2 points)] was originally developed to predict the occurrence of new-onset atrial fibrillation.

Patients' demographic, clinical and routine biochemical parameters were recorded.

The Role of the Redox Non-Innocent Hydroxyl Ligand in the Activation of O Performed by [Ni(H)(OH)].

The cationic complex [Ni(H)(OH)] was previously found to activate dioxygen and methane in gas phase under single collision conditions. These remarkable reactivities were thought to originate from a non-classical electronic structure, where the Ni-center adopts a Ni(II), instead of the classically expected Ni(III) oxidation state by formally accepting an electron from the hydroxo ligand, which formally becomes a hydroxyl radical in the process. Such radicaloid oxygen moieties are envisioned to easily react with otherwise inert substrates, mimicking familiar reactivities of free radicals.
