Abstract
Although conventional cigarette smoking is declining, emerging tobacco related products (ETRPs) are currently gaining ground, especially among the youth. These products include electronic cigarettes, waterpipes/hookah, cigars/cigarillo, smokeless tobacco, and heat-not-burn cigarettes. The observed increase in the use of ETRPs is multifactorial and complex but appears to be mainly driven by efforts from the major tobacco companies to reinvent themselves, and present more appealing and allegedly safe(r) tobacco products. However, it is becoming apparent that these products produce substantial amounts of toxic chemicals, many of which have been shown to exert negative health effects, including in the context of the cardiovascular system. Thus, there has been research efforts, albeit limited in general, to characterize the health impact of these products on occlusive/thrombotic cardiovascular diseases (CVD). In this review, we will discuss the potential impact of ETRPs on thrombosis-based CVD. Specifically, we will review how these products and the major chemicals they produce and/or emit can trigger key players in the process of thrombosis, namely inflammation, oxidative stress, platelets, coagulation, and the vascular endothelium, and the relationship between these effects.

Abstract
Wound healing is a complex physiological process in which the damaged or injured tissue is replaced or regenerated by new cells or existing cells respectively in their synthesized and secreted matrices. Several cells modulate the process of wound healing including macrophages, fibroblasts, and keratinocytes. Apart from these cells, platelet has been considered as a major cellular fragment to be involved in wound healing at several stages by secreting its granular contents including growth factors, thus resulting in coagulation, inflammation, and angiogenesis. A distant cell, which is gaining significant attention nowadays due to its resemblance with platelet in several aspects, is the neuron. Not only neurons but also glia cells are also confirmed to regulate wound healing at different stages in an orchestrated manner. Furthermore, these neurons and glia cells mediate wound healing inducing tissue repair and regeneration apart from hemostasis, angiogenesis, and inflammation by secreting various growth factors, coagulation molecules, immunomodulatory molecules as well as neurohormones, neuropeptides, and neurotrophins. Therefore, in wound healing platelets, neurons and glia cells not only contribute to tissue repair but are also responsible for establishing the wound microenvironment, thus affecting the proliferation of immune cells, fibroblast, and keratinocytes. Here in this review, we will enlighten the physiological roles of neurons and glia cells in coordination with platelets to understand various cellular and molecular mechanism in brain injury and associated neurocognitive impairments.

Expression of ADP receptor P2Y 12, thromboxane A 2 receptor and C-type lectin-like receptor 2 in cord blood-derived megakaryopoiesis. Platelets 2020; 32:618-625.

Abstract
The ADP receptor P2Y12, the thromboxane A2 receptor (TXA2R) and the C-type lectin-like receptor 2 (CLEC-2) mediate platelet activation by different mechanisms. Only little is known about the expression of the receptors in human megakaryopoiesis. Our study aimed to establish a flow cytometry (FC) method for the measurement of P2Y12, TXA2R, and CLEC-2 on platelets of healthy donors and to monitor receptor expression in ex vivo megakaryopoiesis. We determined mean fluorescence intensity (MFI) values of FITC, PE, or APC labeled antibodies binding to the receptors on platelets of 90 healthy donors. For cord blood-derived megakaryopoiesis (CBMK) differentiation of CD34+ cells was induced by IL-3, SCF, and TPO. At 6 time points between day 0 and day 21 of cell culture the MFI values for CD34, CD41, CD61, P2Y12, TXA2R, and CLEC-2 were measured. Quantitative PCR was used for relative quantification of the corresponding mRNA. Transcription factor (TF) binding sites were predicted by in silico analysis of the genes. Platelets showed expectable high MFI values for the platelet marker CD41 (13,716 median MFI). Lower MFI was found for P2Y12 (2,847 median MFI) and CLEC-2 (1,211 median MFI), whereas, binding of the TXA2R antibody revealed even higher values (21,458 median MFI) than CD41. In CBMK the CD34+ cells were negative for P2Y12, TXA2R, and CLEC-2 at day 0. A maximum of 21-fold and 6-fold increase of P2Y12 and TXA2R MFI values, respectively, was found on day 14 to 17. MFI for CLEC-2 increased by 58-fold within the first week and reached a maximum of 1,572-fold increase within the first two weeks of CBMK. Very similar results were obtained on the RNA level. The differential regulation of receptor expression in CBMK was further supported by significant differences in the numbers and types of TF binding sites. P2Y12 and TXA2R, both upregulated only to a low extent in CBMK, probably, are dispensable for megakaryopoiesis. Furthermore, we speculate that CLEC-2 strongly upregulated in early CMBK is important for megakaryopoiesis.

Abstract
Heart failure (HF) is a deadly disease that is difficult to accurately diagnose. Circular RNAs (circRNAs) are a novel class of noncoding RNAs that might play important roles in many cardiovascular diseases. However, their role in HF remains unclear. CircRNA microarrays were performed on plasma samples obtained from three patients with HF and three healthy controls. The profiling results were validated by quantitative reverse transcription polymerase chain reaction. The diagnostic value of circRNAs for HF was evaluated by receiver operating characteristic (ROC) curves. The expression profiles indicated that 477 circRNAs were upregulated and 219 were downregulated in the plasma of patients with HF compared with healthy controls. Among the dysregulated circRNAs, hsa_circ_0112085 (p = 0.0032), hsa_circ_0062960 (p = 0.0006), hsa_circ_0053919 (p = 0.0074) and hsa_circ_0014010 (p = 0.025) showed significantly higher expression in patients with HF compared with healthy controls. The area under the ROC curve for hsa_circ_0062960 for HF diagnosis was 0.838 (p < 0.0001). Correlation analysis showed that the expression of hsa_circ_0062960 was highly correlated with B-type natriuretic peptide (BNP) serum levels. Some differential circRNAs were found to be related to platelet activity by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses. The landscape of circRNA expression profiles may play a role in HF pathogenesis and improve our understanding of platelet function in HF. Moreover, hsa_circ_0062960 has potential as a novel diagnostic biomarker for HF.

Abstract
The chick chorioallantoic membrane (CAM) is a widely used model in medical research and fulfils the requirements laid out in the 3 R's. The CAM, contains a dense network of blood vessels, essential for embryo development but also makes the chick embryo an invaluable resource for the study of angiogenesis and the haemotoxicity of substances. Non-neurotoxic snake venom is responsible worldwide for numerous deaths but also has been found to have a vast range of medicinal benefit. This study combines evaluating the time of onset and intensity of effects of three whole viper venoms (Bitis aritans, Crotalus viridis, Agkistrodon contortrix) at varying concentrations. They were applied onto the CAM, using the Luepke grading system as one method of determining their rapid irritation potential. Regarding the principles of 3 R's, this method helps to evaluate the haemotoxic effect of venom as an alternative method to the rodent tests. The information provided from these results can be used as a rapid tool for both medical management of snakebite wounds and the potential use of snake venom in medical treatments. Then, Luepke grading system can help to evaluate the haemotoxic effect of venom in combination with other appropriate methods.

Abstract
Human blood platelets are major hemostatic regulators in the circulation and important in the mediation of chronic inflammation and immunomodulation. They are key elements that promote cardiovascular pathogenesis that leads to atherosclerosis, thrombosis, myocardial infarction, and stroke. New information on tobacco use and platelet dysregulation shows that these highly understudied vascular cells are dysregulated by tobacco smoke. Thus, platelet function studies should be an important consideration for the evaluation of existing and next-generation tobacco and non-tobacco products. Novel in vitro approaches are being sought to investigate these products and their influence on platelet function. Platelets are ideally suited for product assessment, as robust and novel in vitro translational methods are available to assess platelet function. Furthermore, the use of human biological systems has the advantage that risk predictions will better reflect the human condition.

The effect of physiological levels of South African puff adder (Bitis arietans) snake venom on blood cells: an in vitro model. Sci Rep 2016; 6:35988.

Abstract
A significant burden of illness is caused globally by snakebites particularly by the puff adder, Bitis arietans. Presently there is no reliable and rapid method to confirm envenomation on blood chemistry; although coagulation parameters like prothrombin time, partial thromboplastin time, international normalized ratio and also serum electrolytes are tested. Here, we found that direct in vitro exposure of physiological relevant whole venom levels to human healthy blood (N = 32), caused significant physiological changes to platelet activity using a hematology analyzer, and measuring occlusion time, as well as lyses time, with the global thrombosis test (GTT). Disintegrated platelets were confirmed by scanning electron microscopy (SEM). We also confirmed the pathologic effects on erythrocytes (RBCs) (visible as eryptotic RBCs), by looking at both light microscopy and SEM. Thromboelastography showed that no clot formation in whole blood could be induced after addition of whole venom. We propose further clinical studies to investigate the use of light microscopy smears and hematology analyzer results immediately after envenomation, as a possible first-stage of clinical confirmation of envenomation.
