Abstract
Cardiac injury is common in hospitalized coronavirus disease 2019 (COVID-19) patients and cardiac abnormalities have been observed in a significant number of recovered COVID-19 patients, portending long-term health issues for millions of infected individuals. To better understand how Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2, CoV-2 for short) damages the heart, it is critical to fully comprehend the biology of CoV-2 encoded proteins, each of which may play multiple pathological roles. For example, CoV-2 spike glycoprotein (CoV-2-S) not only engages angiotensin converting enzyme II (ACE2) to mediate virus infection but also directly activates immune responses. In this work, the goal is to review the known pathological roles of CoV-2-S in the cardiovascular system, thereby shedding lights on the pathogenesis of COVID-19 related cardiac injury.

Abstract
Epidemiological studies indicate that prolonged micro-aspiration of gastric fluid is associated in gastroesophageal reflux disease with the development of chronic respiratory diseases, possibly caused by inflammation-related immunomodulation. Therefore, we sought to ascertain the effect of gastric fluid exposure on pulmonary residential cells. The expression of α-smooth muscle actin as a fibrotic marker was increased in both normal human pulmonary fibroblast cells and mouse macrophages. Gastric fluid enhanced the proliferation and migration of HFL-1 cells and stimulated the expression of inflammatory cytokines in an antibody assay. Elevated expression of the Rho signaling pathway was noted in fibroblast cells stimulated with gastric fluid or conditioned media. These results indicate that gastric fluid alone, or the mixture of proinflammatory mediators induced by gastric fluid in the pulmonary context, can stimulate pulmonary fibroblast cell inflammation, migration, and differentiation, suggesting that a wound healing process is initiated. Subsequent aberrant repair in pulmonary residential cells may lead to pulmonary fibroblast differentiation and fibrotic progression. The results point to a stimulatory effect of chronic GERD on pulmonary fibroblast differentiation, and this may promote the development of chronic pulmonary diseases in the long term.

Abstract
Several researchers studied the protective effect of the N-acetylcysteine (NAC) when it was given before the induction of myocardial infarction (MI). Other researchers studied such protective effect when it was before done and after done of the MI. The missing data are the comparison between the protective effect of NAC before myocardial injury with its protective effect both before and after myocardial injury. The aim of the study was to compare the cardioprotective effect of NAC on the isoprenaline-induced myocardial injury before the isoprenaline (ISP) injection with its protective effect both before and after the ISP injection. This study was applied over both short and long time periods. A total of 90 male adult Wistar albino rats were used in the study. The rats were divided into four groups: control group, ISP-treated group, NAC-pretreated group and NAC-pre-& posttreated group. Based on the duration of the experiment, the second and third groups were further subdivided into a and b groups. Histological, immunohistochemical and histomorphometric analysis were used. The myocytes in the ISP-treated groups were fragmented, disrupted with karyolysis. The blood vessels were dilated, congested and associated with blood extravasation, interstitial edema and cellular inflammatory infiltration. Much improvement was observed in the NAC-pretreated group. Focal degeneration was detected in the muscle fibers. The capillaries were normal. Minimal blood extravasation and cellular infiltration were seen. The cardiac muscle fibers in the NAC-pre-& posttreated group were regularly arranged. The mean collagen fiber area percent of the ISP-treated groups was significantly higher by 8.3-folds and 10.1-folds as compared with that of the control group and was also higher by 5.5-folds and 6.8-folds as compared with that of the NAC-pre-&posttreated groups. The α-SMA area percent in the ISP-treated groups was significantly higher by 12.2-folds and 23.9-folds as compared with that of the control group and was higher by 7.5-folds and 15-folds as compared with that of the NAC-pre-& posttreated groups. The mean PCNA area percent of the ISP-treated groups was significantly higher by 126.2 and 164.8% as compared with that of the control group and was higher by 106.3 and 141.5% as compared with that of NAC-pre-& posttreated groups. ISP had deleterious effects on the heart. Administration of NAC before ISP injection could largely reduce the ISP-induced short- and long-term alterations. The protection was maximum with the use of NAC before the ISP injection and continued after the injection for 12 days.

PHARMACEUTICAL BIOLOGY 2016; 54:3226-3231. [PMID: 27687158 DOI: 10.1080/13880209.2016.1216134] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/10/2015] [Revised: 05/09/2016] [Accepted: 06/20/2016] [Indexed: 06/06/2023]
Abstract
CONTEXT A classic traditional Chinese medicine Curcuma aromatica Salisb. (Zingiberaceae) has been reported to have favourable effects on the cardiovascular system. OBJECTIVE To research the cardio-protective effect of different C. aromatica hydroalcoholic extracts on isoproterenol (ISO)-induced acute myocardial ischemia (AMI) in rats. The total phenols in different extracts were detected simultaneously. MATERIALS AND METHODS The rhizomes of C. aromatica dry powder were refluxed with 30%, 50%, 70% and 90% hydroalcoholic solvents to obtain different extracts. Rats were pretreated with four C. aromatica extracts (150 mg/kg/day, i.g.) for 9 days and then given ISO (30 mg/kg/day, s.c.) for 2 consecutive days, respectively. Heart rate, ST-segment, T-wave and serum levels of CK-MB, LDH, TAC, SOD, NO and MDA were measured. Total phenols of the different extracts were determined using the Folin-Ciocalteu assay. RESULTS Pretreatment with C. aromatica significantly decreased the elevated levels of serum specific cardiac injury biomarkers (CK-MB and LDH), the serum level of MDA, the ST-segment and T-wave. In addition, C. aromatica increased the heart rate, as well as the levels of TAC, SOD and NO, compared to ISO-induced controls. The total phenols in the 70% extract were higher than in the other extracts reaching 5.629 ± 0.037 mg/g, crude drug. DISCUSSION AND CONCLUSION Curcuma aromatica hydroalcoholic extracts exhibited remarkable cardio-protective effects against AMI in rats. The 70% extracts showed the strongest bioactivity. These results indicate that ethanol concentration in preparation of extracts of C. aromatica plays an important role in the protective effect against AMI.

Abstract
Choline has been identified as an essential nutrient with crucial role in many vital biological functions. Recent studies have demonstrated that heart dysfunction can develop in the setting of choline deprivation even in the absence of underlying heart disease. Matrix metalloproteinases (MMPs) are responsible for extracellular matrix degradation, and the dysregulation of MMP-2 and MMP-9 has been involved in the pathogenesis of various cardiovascular disorders. The aim of the study was to investigate the role of MMPs and their inhibitors (TIMPs), in the pathogenesis of choline deficiency-induced cardiomyopathy, and the way they are affected by carnitine supplementation. Male Wistar Albino adult rats were divided into four groups and received standard or choline-deficient diet with or without L-carnitine in drinking water (0.15% w/v) for 1 month. Heart tissue immunohistochemistry for MMP-2, MMP-9, TIMP-1, and TIMP-2 was performed. Choline deficiency was associated with suppressed immunohistochemical expression of MMP-2 and an increased expression of TIMP-2 compared to control, while it had no impact on TIMP-1. MMP-9 expression was decreased without, however, reaching statistical significance. Carnitine did not affect MMP-2, MMP-9, TIMP-1 or TIMP-2 expression. The pattern of TIMP and MMP modulation observed in a choline deficiency setting appears to promote fibrosis. Carnitine, although shown to suppress fibrosis, does not seem to affect MMP-2, MMP-9, TIMP-1 or TIMP-2 expression. Further studies will be required to identify the mechanism underlying the beneficial effects of carnitine.

Abstract
Background Chronic pancreatitis (CP) is a necroinflammatory process resulting in extensive pancreatic fibrosis. Granulocyte colony-stimulating factor (G-CSF), a hematopoietic stem cell mobilizer, has been shown to exert an anti-fibrotic effect partly through the enrichment of bone marrow (BM) cells in fibrotic organ. We aimed to test the effect of G-CSF on fibrosis in a mouse model of CP. Methods CP was induced in C57Bl/6J mice by consecutive cerulein injection (50 µg/kg/day, 2 days a week) for 6 weeks. Mice were then treated with G-CSF (200 µg/kg/day, 5 day a week) or normal saline for 1 week, and sacrificed at week 7 or week 9 after first cerulein injection. Pancreatic histology, pancreatic matrix metallopeptidase 9 (MMP-9), MMP-13 and collagen expression were examined. Pancreatic myofibroblasts were isolated and cultured with G-CSF. Collagen, MMP-9 and MMP-13 expression by myofibroblasts was examined. The BM-mismatched mice model was used to examine the change of BM-derived myofibroblasts and non-myofibroblastic BM cells by G-CSF in the pancreas. Results The pancreatic collagen expression were significantly decreased in the G-CSF-treated group sacrificed at week 9. While collagen produced from myofibroblasts was not affected by G-CSF, the increase of MMP13 expression was observed invitro. There were no effect of G-CSF in the number of myofibroblasts and BM-derived myofibroblasts. However, the number of non-myofibroblastic BM cells and macrophages were significantly increased in the pancreata of cerulein- and G-CSF-treated mice, suggesting a potential anti-fibrotic role of non-myofibroblastic BM cells and macrophages stimulated by G-CSF. Conclusions Our data indicated that G-CSF contributed to the regression of pancreatic fibrosis. The anti-fibrotic effects were possibly through the stimulation of MMP-13 from myofibroblasts, and the enhanced accumulation of non-myofibroblastic BM cells and macrophages in the pancreas.

Abstract
The aim of this study was to evaluate whether exercise training (ET) prevents or minimizes cardiac dysfunction and pathological ventricular remodeling in ovariectomized rats subjected to myocardial infarction (MI) and to examine the possible mechanisms involved in this process. Ovariectomized Wistar rats were subjected to either MI or fictitious surgery (Sham) and randomly divided into the following groups: Control, OVX+SHAMSED, OVX+SHAMET, OVX+MISED and OVX+MIET. ET was performed on a motorized treadmill (5x/wk, 60 min/day, 8 weeks). Cardiac function was assessed by ventricular catheterization and Dihydroethidium fluorescence (DHE) was evaluated to analyze cardiac oxidative stress. Histological analyses were made to assess collagen deposition, myocyte hypertrophy and infarct size. Western Blotting was performed to analyze the protein expression of catalase and SOD-2, as well as Gp91phox and AT1 receptor (AT1R). MI-trained rats had significantly increased in +dP/dt and decreased left ventricular end-diastolic pressure compared with MI-sedentary rats. Moreover, oxidative stress and collagen deposition was reduced, as was myocyte hypertrophy. These effects occurred in parallel with a reduction in both AT1R and Gp91phox expression and an increase in catalase expression. SOD-2 expression was not altered. These results indicate that ET improves the functional cardiac parameters associated with attenuation of cardiac remodeling in ovariectomized rats subjected to MI. The mechanism seems to be related to a reduction in the expression of both the AT1 receptor and Gp91phox as well as an increase in the antioxidant enzyme catalase, which contributes to a reduction in oxidative stress. Therefore, ET may be an important therapeutic target for the prevention of heart failure in postmenopausal women affected by MI.

Abstract
Melatonin was previously shown to reduce blood pressure and left ventricular (LV) remodeling in several models of experimental heart damage. This study investigated whether melatonin prevents LV remodeling and improves survival in isoproterenol-induced heart failure. In the first experiment, four groups of 3-month-old male Wistar rats (12 per group) were treated for 2 wk as follows: controls, rats treated with melatonin (10 mg/kg/day) (M), rats treated with isoproterenol (5 mg/kg/day intraperitoneally the second week) (Iso), and rats treated with melatonin (2 wk) and isoproterenol (the second week) in corresponding doses (IsoM). In the second experiment, 30 rats were treated with isoproterenol and 30 rats with isoproterenol plus melatonin for a period of 28 days and their mortality was investigated. Isoproterenol-induced heart failure with hypertrophy of the left and right ventricles (LV, RV), lowered systolic blood pressure (SBP) and elevated pulmonary congestion. Fibrotic rebuilding was accompanied by alterations of tubulin level in the LV and oxidative stress development. Melatonin failed to reduce the weight of the LV or RV; however, it curtailed the weight of the lungs and attenuated the decline in SBP. Moreover, melatonin decreased the level of oxidative stress and of insoluble and total collagen and partly prevented the beta-tubulin alteration in the LV. Most importantly, melatonin reduced mortality and prolonged the average survival time. In conclusion, melatonin exerts cardioprotective effects and improves outcome in a model of isoproterenol-induced heart damage. The antiremodeling effect of melatonin may be of potential benefit in patients with heart failure.
