BACKGROUND: Multipotent mesenchymal stromal cell (MSC) therapy has been widely recognized as a feasible strategy for regenerating injured myocardial tissue. However, little is known about the efficacy of intravenous injection of allogeneic umbilical cord (UC) MSCs in preclinical models of porcine myocardial infarction. METHODS: Different dosages of allogeneic UC-MSCs or the vehicle [phosphate-buffered saline (PBS)] were delivered intravenously into an acute myocardial infarction (AMI) porcine model twice after coronary ligation...

Sensitive detection of biomarkers will mean accurate and early diagnosis of diseases. A tissue plasminogen activator (tPA) has a crucial role in many cardiovascular diseases and it is related to many processes such as angiogenesis in cancer cells. Therefore, sensitive determination of tPA is important in diagnosis and clinical research. tPA monoclonal antibody was covalently attached onto single-wall carbon nanotubes (SWCNTs) using diimide-activated imidation coupling. Functionalized SWCNTs were immobilized onto a glassy carbon electrode and the modification process was investigated by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), SEM, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS)...

The P2Y12 receptor plays a critical role in the amplification of platelet aggregation in response to various agonists and stable thrombus generation at the site of vascular injury leading to deleterious ischemic complications. Therefore, treatment with a P2Y12 receptor blocker is a major effective strategy to prevent ischemic complications in high-risk patients with acute coronary syndrome (ACS) and patients undergoing percutaneous coronary intervention (PCI). The determination of optimal platelet inhibition is based on maximizing antithrombotic properties while minimizing bleeding risk and is critically dependent on individual patient's propensity for thrombotic and bleeding risks...

Previous empirical studies have shown that both spiritual well-being (SWB) and death anxiety (DA) significantly affect the mental health of patients with acute diseases. In this regard, our paper contributes to the extant literature by scrutinizing the conditional relationship between SWB and DA as well as the various mechanisms underpinning such a relationship in patients with acute myocardial infraction (AMI). A descriptive, correlational methodology was utilized. Our main sample consisted of 300 patients with acute myocardial infraction who were hospitalized in a specialized medical institution in Iran throughout a two-month period (i...

Type 2 Myocardial Infarction (Type 2 MI) is considered to result from an imbalance between demand and supply of oxygen in the myocardium, other than coronary plaque instability. It is highly prevalent in internal departments and is strongly associated with mortality. To date, there is no consensus regarding the diagnostic criteria for type 2 MI and no available guidelines regarding the optimal management of this condition. We present a case study of a 64 years old male who was hospitalized with lower gastrointestinal bleeding...

For decades, mesenchymal stem (MSCs) cells have been used for cardiovascular diseases as regenerative therapy. This review is an attempt to summarize the types of MSCs involved in myocardial infarction (MI) therapy, as well as its possible mechanisms effects, especially the paracrine one in MI focusing on the studies (human and animal) conducted within the last 10 years. Recently, reports showed that MSC therapy could have infarct-limiting effects after MI in both experimental and clinical trials. In this context, various types of MSCs can help cardiac regeneration by either revitalizing the cardiac stem cells or revascularizing the arteries and veins of the heart...
