While African Health Sciences has been freely accessible online there have been questions on whether it is Open Access or not. We wish to clearly state that indeed African Health Sciences is Open Access. There are key issues regarding Open Access needing clarification for avoidance of doubt:
- 1. Henceforth, papers in African Health Sciences will be published under the CC BY (Creative Commons Attribution License) 4.0 International. See details on https://creativecomons.org/)
- 2. The copyright owners or the authors grant the 3rd party (perpetually and in advance) the right to disseminate, reproduce, or use the research papers in part or in full, format/medium as long as:
- No substantive errors are introduced in the process
- Attribution of authorship and correct citation details are given
- The referencing details are not changed.
Should the papers be reproduced in part, this must be clearly stated.
- 3. The papers will be freely and universally accessible online in an easily readable format such as XML in at least one widely recognized open access repository such as PUBMED CENTRAL.

Plasma soluble lectin-like oxidized low-density lipoprotein receptor-1 acts as a new biomarker for NSTEMI and STEMI patients
Abstract
Objective: The diagnostic significance of plasma soluble lectin-like oxidized low-density lipoprotein receptor-1(sLOX-1) for non-ST segment elevated myocardial infarction (NSTEMI) and ST segment elevated myocardial infarction (STEMI) were explored by this study.
Methods: In this study, 107 acute NSTEMI, 223 acute STEMI and 107 healthy subjects, and hypoxic (1%02) ventricular cardiomyocytes H9c2 were used.
Results: The significantly up-regulated plasma sLOX-1 levels in acute NSTEMI and STEMI patients compared to healthy subjects (p<0.001). Both male and female NSTEMI and STEMI groups had remarkably higher concentrations of plasma sLOX-1 levels than controls (p<0.001). The circulating levels of sLOX-1 expression obviously elevated in elderly aging (60-75 years) than younger aging (30-45 years) both male and female in healthy subjects as well as NSTEMI and STEMI (p<0.001). Altered levels of sLOX-1 in blood plasma revealed a significant discrimination with high sensitivity and specificity between healthy with NSTEMI and STEMI subjects with AUC= 0.916 and AUC= 0.925 respectively. Moreover, LOX-1 levls were highly released from 6hour, 12hour and 18hour hypoxic injured H9c2 cells than normoxic cell (p<0.001),reflected circulating plasma sLOX-1 in AMI patients.
Conclusion: Elevated levels of plasma sLOX-1concentrations might be used as a clinical biomarker for early recognition of NSTEMI and STEMI patients. Multicenter larger scale studies are necessary before use in clinical practice.
