Abstract
This case report details a challenging instance of undifferentiated/unclassified cardiac sarcoma in a 28-year-old female, presenting with diverse symptoms like muscle weakness, shortness of breath, and hemoptysis. Diagnostic hurdles led to an initial misdiagnosis of granulomatosis with polyangiitis before discovering a sizable left atrial mass, ultimately diagnosed as high-grade undifferentiated/unclassified sarcoma. Despite initial surgical intervention, the patient's condition worsened, underscoring the complexities in managing such cases involving cardiac sarcomas. This case emphasizes the diagnostic complexities associated with primary cardiac sarcomas, particularly the challenges in achieving accurate diagnoses and formulating effective treatment strategies.

Abstract
Hair loss occurs in patients with Androgenetic Alopecia (AGA). The pattern of hair loss is different between men and women. The main cause of hair loss is increased cell apoptosis and decreased regeneration, proliferation and differentiation processes in hair follicles. Long Non-Coding RNAs (lncRNAs) are one of the most important molecules that regulate the processes of apoptosis, regeneration, proliferation and differentiation in hair follicles. Since studies have shown that lncRNAs can be effective in the development of cardiotoxicity and induction of cardiovascular disease (CVD); so effective lncRNAs in the regulation of regeneration, proliferation, differentiation and apoptosis of hair follicles can be involved in the development of CVD in AGA patients with. Therefore, this study investigated the lncRNAs involved in increasing apoptosis and reducing the processes of regeneration, proliferation and differentiation of hair follicles. The aim of the current study was to evaluate the role of lncRNAs as a risk factor in the incidence of CVD in AGA patients; it will help to design treatment strategies by targeting signaling pathways without any cardiotoxicity complications.

Abstract
Exosomes are spherical bilayer membrane vesicles with an average diameter of 40-100 nm. These particles perform a wide range of biological activities due to their contents, including proteins, nucleic acids, lipids, lncRNA, and miRNA. Exosomes are involved in inflammation induction, oxidative stress and apoptosis, which can be effective in endothelial dysfunction. Due to the induction of mentioned processes in the endothelial cells, the intercellular connections are destroyed, cell permeability increases and finally cell efficiency decreases and functional defects occur. Cardiovascular disease (CVDs) are of consequences of endothelial dysfunction. Thus by identifying the exosome signaling pathways, which induce inflammation, oxidative stress, and apoptosis, endothelial dysfunction and subsequently CVDs can be reduced; exosomes can be used for appropriate target therapy.

Abstract
Background: The superior type of sinus venosus atrial septal defect (SVASD) is a rare form of the atrial septal defect (ASD) in which the upper part of the atrial septum does not exist. The presence of other cardiac anomalies such as anomalous pulmonary venous connections has been reported in this type of congenital heart disease. This study aimed to assess the presence of the patent foramen ovale (PFO) in patients with the superior type of SVASD. Methods: This retrospective case-control study on 387 patients, consisting of 187 patients with a definite SVASD and 200 patients with problems other than the ASD, was conducted in Rajaie Cardiovascular Medical and Research Center between February 2005 and July 2014. Seven patients with inadequate data were excluded from the analysis. The presence/absence of the PFO was also evaluated in the case and control groups. Results: The analyses were performed on 182 male and 198 female patients at a mean age of 39.07±14.41 and 51.01±15.80 years in the case and control groups, respectively. The PFO was significantly more frequent in the patients with the superior type of SVASD than in those without the condition (P<0.001). The persistence of the left superior vena cava was seen in 34 out of 180 patients with SVASD and in 1 out of 200 patients without the condition (18.9% vs 0.5%; P<0.001). Conclusion: This study was the first to highlight the coexistence of the PFO and the superior type of SVASD. Physiological, genetic, or fetal factors may play an important role in the association between the PFO and the SVASD.

Abstract
This study examined the relationship between global longitudinal strain (GLS) and pulmonary function tests (PFT) in patients with systemic sclerosis (SS) and normal ejection fraction (EF) and pulmonary artery pressure (PAP) and healthy controls. Sixty patients in two groups underwent extensive screening, including echocardiography, physical examination, the modified Rodnan Skin Score, and pulmonary function tests. Pulmonary interstitial disease was diagnosed by the pulmonary function test and by CT scan in case of indication. GLS score was computed as the mean peak systolic strain for 17 segments. The mean GLS score was - 18.36 ± 2.1 in the case group and - 20.66 ± 1.6 in the control group (P value < 0.001). GLS scores had a significant inverse relationship with the forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) ratio (P value = 0.049) and both FEV and FVC in patients younger than 35 years old (P = 0.046 and 0.049, respectively). GLS scores had no significant relationship with time elapsed since the onset of skin manifestations, and Raynaud phenomenon, Rodnan score, EF, systolic PAP, or the six-minute walk test results. The patients' six-minute walk test had a significant positive relationship with FVC and right ventricular end diastolic diameter (P value = 0.018 and 0.047, respectively). According to our findings, GLS is significantly lower in patients with SS (with normal EF & PAP) than in healthy individuals. It is also related with certain pulmonary function indices including FEV1/FVC. The reduction in GLS is associated with reduced pulmonary function strength.

Abstract
Intramyocardial dissection (IMD) with ventricular septal rupture (VSR) following myocardial infarction (MI) is a rare subacute form of cardiac rupture. The evidence available in this regard is scarce. We aimed to share our experience and conduct a systematic review of previous cases. We searched the literature and performed a systematic review of previous cases. A total of 37 cases of IMD with VSR were included (1 our original and 36 literature cases). Mean age was 68 ± 8 years and 20 (54.1%) patients were male. Anterior and inferior MI were observed in 14 (37.8%) and 23 (62.2%) cases, respectively. The dissected area was the septum, RV, both septum and RV, or LV apex in 21 (56.8%), 9 (24.3%), 5 (13.5%), and 2 (5.4%), respectively. Apicoseptal and inferoseptal VSR were observed in 15 (40.5%) and 22 (59.5%) cases, respectively. At least one occluded artery was observed in 29 (90.6%) of cases. Reperfusion therapy was done for 15 (40.5%) cases before the VSR occurred. Surgery, percutaneous, and medical therapy were done for 26 (70.3%), 3 (8.1%), and 7 (18.9%) cases, respectively. The mortality rate was significantly higher in the medical versus surgical-treated group (85.7% versus 42.3%, P = .027). There was a trend to higher mortality in the group with dissection of both septum and RV (P = .15). We concluded that echocardiography has a critical role in diagnosing this complication. Surgery is mandatory in IMD with VSR.

Abstract
BACKGROUND Heart failure is the biggest cause of mortality and morbidity in people with thalassemia, and iron deposition in cardiac tissue impairs cardiovascular function. Therefore, early detection of cardiac involvement is important to improve the prognosis in these individuals. METHOD Two- and three-dimensional echocardiography was performed to evaluate left ventricular ejection fraction (LVEF), left ventricular volumes and diameters, and global longitudinal strain (GLS) in 130 individuals with β-thalassemia using the speckle tracking method. Magnetic resonance imaging (MRI) was carried out on both the heart and liver. The participants were divided into 2 groups based on cardiac T2* values (normal and abnormal cardiac iron load), and the correlation between cardiac T2* MRI and GLS was evaluated. RESULTS The statistical analysis showed a significant correlation between cardiac T2* MRI and left ventricular global longitudinal strain. There was a significant difference in global longitudinal strain (P < .0001), liver MRI T2*( P < .0001), and left ventricular ejection fraction (P < .001) between the 2 groups. The optimal cutoff value for GLS was -18.5% with sensitivity and specificity 73.0% and 63.0%, respectively (postitive predictive value = 50%, negative predictive value = 82.3%, AUC = 0.742, std. error = 0.046) which predicts T2* value of <20 ms, according to cardiac MRI. CONCLUSIONS The participants with cardiac iron overload had a lower GLS than those without one. This suggests that GLS may be a useful method to predict myocardial iron overload particularly in β-thalassemia patients with subclinical cardiac involvement.

Abstract
Left ventricular (LV) diverticulum is a relatively rare condition, and it is important to differentiate it from pseudoaneurysm. The increasing use of noninvasive imaging modalities can help to demonstrate different types of ventricular outpouching structures. We report a case of congenital LV diverticulum that is much larger than the usual size and is diagnosed with tissue Doppler echocardiography and cardiac magnetic resonance imaging. Although a ventricular diverticulum is mostly asymptomatic, in the case of this particular patient, it has become complicated with infective endocarditis. <Learning objective: Congenital ventricular diverticulum is a rare finding and can be diagnosed with noninvasive imaging modalities such as tissue Doppler echocardiography and cardiac magnetic resonance imaging rather than surgery. Although congenital ventricular diverticulum is asymptomatic in most cases, infective endocarditis is a known complication.>.

Abstract
One of the drawbacks of typical dye-sensitized solar cells (DSCs) is their high cost and the high electrical resistance of the transparent conducting substrate. In conventional sandwich-type DSCs, only one of the FTO substrates can be replaced by a metal substrate. We investigated an all-metal-electrode single-sided DSC in which interpenetrated bracken-like Cr electrodes were created using photolithography; mesoporous TiO2 and Pt films were deposited on the laterally separated electrodes. Thermal Pt deposition and electrodeposition methods were investigated and it was found that a cyclic electrodeposition method resulted in selective Pt deposition at room temperature with a higher device performance. Cu or ZnO sacrificial layers and TiO2 or TiO2/SiO2 porous layers were used for the spacer layer that keeps the Pt electrode away from the TiO2 mesoporous layer and the optimum results were obtained when a TiO2/SiO2 layer was used. The best device had a current density of 8.47 mA cm(-2), an open circuit voltage of 0.685 V and an efficiency of 2.44%. The results of open circuit voltage decay and electrochemical impedance spectrometry showed the formation of a high-resistivity blocking layer, which was attributed to the Cr oxide formed during thermal treatment. The efficiency may be improved further by developing low-temperature fabrication processes.

Abstract
BACKGROUND AND THE PURPOSE OF THE STUDY sBesides its hematopoietic effects, erythropoietin (EPO) by mobilization of iron and modulation of some inflammatory cytokines has antioxidant and anti-inflammatory properties. The purpose of this study was to evaluate these effects of erythropoietin and its impact on organ function in traumatized patients. METHODS Twenty-six ICU-admitted traumatized patients within 24 hrs after trauma were randomly assigned to the EPO (received EPO, 300 units/Kg/day) and Control (not received EPO) groups. The inflammatory biomarkers including Tumor Necrosis Factor alpha (TNF-α), Interleukin 1 (IL-1), Plasminogen Activator Inhibitor 1 (PAI-1) and Nitrotyrosine were recorded at the admission, 3, 6 and 9 days thereafter. Acute Physiology and Chronic Health Evaluation (APACHE II) and Sequential Organ Failure Assessment (SOFA) scores were also recorded. RESULTS Among 12 patients (EPO group) TNF-α level at the day of 9 (P=0.046), and within EPO group at the days of 3 (P=0.026 ameliorate), 6 (P=0.016), and 9 (P=0.052) were significantly lowered. Level of IL-1 and PAI-1 decreased significantly at days of 3, 6 and 9 post intervention. Also there were significant differences between two groups in the SOFA score during three measured time intervals (the first, third and seventh days). CONCLUSION From the results of this study it seems that injection of erythrocyte stimulating agent is well tolerated and inhibits the inflammatory response and oxidative stress following trauma.
