Because of the rapid and serious nature acute cardiovascular disease (CVD) especially ST segment elevation myocardial infarction (STEMI), a leading cause death worldwide, prompt diagnosis treatment is crucial importance to reduce both mortality morbidity. During pandemic such as coronavirus disease-2019 (COVID-19), it critical balance emergencies with infectious risk. In this work, we recommend using wearable device based mobile health (mHealth) an early screening real-time monitoring tool...

Aim: Photoplethysmography (PPG) has gained widespread popularity as a non-invasive method for potential cuff-less blood pressure (BP) measurement in smart devices. However, the accuracy of PPG-based devices is often hindered by motion artifacts, site variability, and inconsistent contact force (CF). This study aims to investigate influence CF variations on PPG signals. Methods: To address these challenges, we present novel approach involving multi-channel array integrated with regulation...

Complement factor D (FD), a highly specific S1 serine protease, plays central role in the amplification of alternative complement pathway (AP) innate immune system. Dysregulation AP activity predisposes individuals to diverse disorders such as age-related macular degeneration, atypical hemolytic uremic syndrome, membranoproliferative glomerulonephritis type II, and paroxysmal nocturnal hemoglobinuria. Previously, we have reported screening efforts identification reversible benzylamine-based...

Soluble guanylate cyclase (sGC), the endogenous receptor for nitric oxide (NO), has been implicated in several diseases associated with oxidative stress. In a pathological environment, heme group of sGC can be oxidized becoming unresponsive to NO leading loss ability catalyze production cGMP. Recently dysfunctional sGC/NO/cGMP pathway contributing elevated intraocular pressure glaucoma. Herein we describe discovery molecules specifically designed topical ocular administration, which activate...

Different from the traditional methods of assessing cardiac activities through heart rhythm statistics or P-QRS-T complexes separately, this study demonstrates their interactive effects on power density spectrum (PDS) ECG signal with applications for diagnosis ST-segment elevation myocardial infarction (STEMI) diseases. Firstly, a mathematical model PDS random pacing pulse train (PPT) mimicking S-A node firings was derived. Secondly, an experimental analysis performed clinical signals 49...

The measurement and monitoring of continuous arterial blood pressure (BP) have undergone significant evolution over the past 170 years, transitioning from ancient invasive approaches, like kymograph, to modern non-invasive unobtrusive technologies such as tonoarteriography (TAG). This progressive shift has revolutionized way we track BP, providing safer, more accurate, convenient methods for BP. paper aims provide some historical perspectives on development BP technology, highlight key...

Abstract Mesenchymal stem cells (MSCs) belong to the family of pluripotent cells, which have an obvious multi-directional differentiation potential and can regulate immune response organism by influencing cell subsets, thus they excellent prospects for application in inflammation, diseases, organ transplantation. Numerous studies shown that MSCs are a promising strategy treatment cardiovascular disease modulating subsets coordinating local systemic innate adaptive responses, thereby enabling...

Proximal tibial aspect ratio (PTAR) is closely related to age, disease status and cutting parameters with considerable inter-individual variation independent of gender race, nevertheless the components from different manufacturers remains relatively constant smallest largest size. As a result, component mismatching an unavoidable dilemma during tibia preparation in total knee arthroplasty (TKA). Various prosthesis systems all can achieve more than 80% coverage on proximal tibia, whereas...
