Abstract
Objective:
The tissue remodeling process and cellular migration relate to the activities of matrix metalloproteinases (MMPs). The aim of this study was to investigate the effects of a predicted motif from TIMPs on the MMP-2 and MMP-9 activities secreted from the differentiated macrophages.
Methods and Materials:
The monocytes were isolated from the healthy individuals by RosetteSep kit and were differentiated into macrophages using M-CSF. A 4-amino acid motif (TCAP) was predicted using bioinformatics tools. Zymography technique was applied for the measurement of MMP activities. The docking studies were also investigated between MMPs, tetrapeptide, and Batimastat.
Results:
The TCAP inhibited significantly the differentiated macrophage MMP-2 and MMP-9 activities (p=0.0001and p=0.01, respectively). The docking results suggested the some MMP amino acids are involved with both tetrapeptide (TCAP), and Batimastat,
Conclution:
The data showed that the small motif (TCAP) of TIMPs inhibits effectively the MMP-2 activity.

Abstract
BACKGROUND In-stent restenosis usually occurs by platelet activation, neointima formation, VSMC migration, and proliferation in the position of the vessel stent. The monocytes have a magnificent role in neointimal hyperplasia since these cells recruit to the site of vessel injury through chemokines and other secretion proteins. This study is focused on the investigation of vitronectin, miR-193, miR-34, and miR-520 expression levels in PBMCs isolated from stenosed patients. METHODS A total of sixty subjects undergoing coronary artery angiography containing patients with stent no restenosis (n = 20), in-stent restenosis (n = 20), and healthy participants (n = 20) participated in the study. The vitronectin, miR-193, miR-34, and miR-520 expression levels were measured by the RT-qPCR technique. Data were analyzed by SPSS software. RESULTS The vitronectin, miR-34, and miR-520 expression levels changed significantly in patients with vessel in-stent restenosis (p = 0.02, p = 0.02, and p = 0.01, respectively). Furthermore, there were inverse correlations between the expression levels of vitronectin gene and miR-34 (r = - 0.44, p = 0.04) as well as miR-520 (r = - 0.5, p=0.01). CONCLUSIONS The molecular events in the vessel stenosis may be affected by targeting vitronectin with miR-520 and miR-34.

Abstract
OBJECTIVES Present investigation was carried out to evaluate the mRNA level of TNF receptor type 1 (TNFR1) and TNF receptor type 2 (TNFR2) in peripheral-blood cells in patients with premature CAD over healthy controls. BACKGROUND TNFα as a pleiotropic cytokine could be concerned in cardiovascular pathophysiology regarding its special effects on endothelial cells. TNFα exerts its activities through its receptors, TNFR1 and TNFR2. METHODS Totally, 40 patients with premature CAD and 40 healthy controls were studied. The qRT-PCR technique was used to determine the mRNA level of TNFR1 and TNFR2 in tested groups. RESULTS The results of this study show that the relative expression was 1.32 ± 0.34 in cases and 1.11 ± 0.16 in controls for TNFR1. The relative expression was 0.96 ± 0.13 in cases and 1.49 ± 0.41 in controls for TNFR2. There is no significant difference in the level of gene expression in the studied groups regarding TNFR1 and TNFR2 genes (p > 0.05). CONCLUSION It can be concluded that the mRNA levels of TNFR1 and TNFR2 were not associated with CAD risk. Studies with more details, larger sample size, and new risk loci are necessary to reveal disease-causing mechanisms in the pathogenesis of CAD (Fig. 3, Ref. 21).

Abstract
BACKGROUND Iron overload is the main transfusion related side effects in patients with transfusion dependent hemoglobinopathies. Severe iron deposition in tissues leads to organ dysfunction. Many organs can be affected such as heart, liver, and endocrine organs. Cardiac failure and liver fibrosis are the consequent of Iron overload in transfusion dependent hemoglobinopathy. Magnetic Resonance Imaging (MRI) is a safe, noninvasive, and accurate method for the assessment of iron deposition in different tissues. This study assessed iron levels in liver and heart of the patients with transfusion dependent hemoglobinopathies. MATERIALS AND METHODS The studied population consisted of 12 patients (7 male and 5 female) with transfusion dependent hemoglobinopathies, aged between 10-18 years old. Then, Cardiac and liver T2*- weighted magnetic resonance imaging (MRI) were obtained. RESULTS In current study, 1patient (8.33%) had severe, 2 patients (16.66%) had moderate and 2(16.66%) had mild cardiac iron deposition. Out of 12 patients, 1 had severe iron deposition in liver (8.33%), 5(41.66%) and 4(33.33%) had moderate and mild hepatic iron deposition, respectively. Differences between Hepatic and cardiac iron levels were not significant between males and females (p>0.05). CONCLUSION Since cardiac and liver iron levels were higher than normal in most of the study group, checking ferritin level and liver function test and also echocardiography in shorter intervals (each 3 months) in involved group is suggested instead of checking routinely in 6 month intervals in patients with transfusion dependent hemoglobinopathies.

Abstract
In this study the anticonvulsant effect of two dihydropyridine derivatives [diethyl -1,4- dihydro -2,6-dimethyl -4-(4- fluoro benzyl-2- methylthio -5- imidazolyl)-3,5- pyridine dicarboxilat (A) and diethyl -1,4-dihydro -2,6- diethyl -4-(4- fluoro benzyl-2- methylthio -5- imidazolyl)-3,5- pyridine dicarboxilat (B)] by pentylenetetrazole (PTZ) and electroshock in mice was evaluated. The latency and HLTE (hind limb tonic extensions), the duration of HLTE and the mortality protection in pentylenetetrazole test and the HLTE duration in electroshock test were assessed. Both compounds had significant differences with negative control in all doses used. There was no significant difference between nifedipine and B (96.7 and 169.2 mg/kg doses) in the starting point of HLTE and between nifedipine andA(62.2 and 108.9 mg/kg doses) in the duration of HLTE in the PTZ test. Also, there was no significant difference between nifedipine and B (96.7 and 169.2 mg/kg doses) andA(62.2 and 108.9 mg/kg doses) in electroshock test. All doses ofAand B and nifedipine showed less effect than phenytoin and valproate. This study showed that bothAand B have anticonvulsant activity in the PTZ-induced seizure model and the MES test. These compounds, thus, might be useful in the petit mal and grand mal epilepsy.

Abstract
BACKGROUND This study was designed to assess and compare the quantity and quality of Iranian and Turkish researchers working in the field of Parasitology from bibliometric point of view. METHODS To assess the contributions and achievements of the Iranian and Turkish parasitologists, bibliometric analysis was carried out based on the citation data retrieved from Web of Science. RESULTS The absolute productivity of Turkish and Iranian parasitologists' papers has almost tripled for Turkey, from 12 papers in 2002 to 36 papers in 2011, and decuple for Iran, from 10 papers to 123 from 2002 to 2010. The average number of citation per article is about 5.8 and 4 for Turkish and Iranian parasitologists' papers, respectively. The "Veterinary Parasitology" journal was the most cited journal in both countries. The majority (more than 90%) of cited items was foreign journal articles and one half of all references in journals articles dated 11 and 12 years while one half of cited books was dated within 14 to16 years for Turkish and Iranian papers, respectively. CONCLUSION Based on observed data and applied model, it is anticipated that the total number of Iranian and Turkish parasitologists' publications in Web of Science will exceed of 2512 and 240 articles per annum for Iranian and Turkish in 2020, respectively.
