Abstract
Introduction Coronary artery disease (CAD) is the main cause of death and is characterized by atherosclerosis in coronary arteries. Inflammation plays a crucial role in the progression and development of atherosclerosis. Methods The present study consisted of 132 Iranian individuals who underwent coronary angiography, 65 patients with CAD, and 67 controls. The matrix metalloproteinase-9 (MMP-9), TNF-α, IL-6, and vitamin D serum levels were measured by the ELISA technique. The gene expression of MMP-9 and tissue inhibitors of metalloproteinase (TIMP-1) was estimated by real-time PCR assay. Results A considerable increase in levels and PBMC gene expression of MMP-9 and serum levels of IL-6 and TNF-α were found in CAD patients compared with controls. A significant decrease was detected in vitamin D levels of CAD patients in comparison with controls. A considerable direct correlation was found between MMP-9 levels and MMP-9 and TIMP1 gene expression in CAD patients. MMP-9 levels positively correlated with LDL-C in CAD patients. The correlation between TIMP1 gene expression and IL-6 levels was also negatively significant. There were positive correlations between MMP-9 levels with IL-6 and TNF-α serum levels in CAD patients. Conclusion This study showed that the interaction between MMPs, TIMP1, and cytokines could play a role in the pathogenesis of atherosclerosis. The present study suggested that high levels of TNF-α and IL-6 and vitamin D deficiency in our studied patients could disturb the MMP-9/TIMP-1 balance and lipid metabolism, leading to plaque formation/ rupture in predisposed CAD patients.

Abstract
OBJECTIVE An association between microRNAs (miRNAs) and adhesion proteins expression with repeated implantation failure (RIF) has been recently reported; however, these findings are controversial. This study aims to evaluate the endometrial and circulating expressions of miR-145, miR-155-5p, and miR-224 in addition to the endometrial expressions of membrane protein palmitoylated-5 (MPP-5) and endothelial cell adhesion molecule-1 (PECAM-1) in patients with RIF compared to control subjects. MATERIALS AND METHODS This case-control study was carried out between June 2021-July 2022. Subjects included 17 patients with RIF and 17 control subjects, who had previous spontaneous term pregnancy with a live birth, who referred to the Medical Centre of Arash Hospital, Tehran, Iran. Endometrial tissue samples were obtained via hysteroscopy and Pipelle catheter in the RIF and control subjects, respectively. Plasma samples were collected after ovulation in all subjects. The expression levels of MPP5, PECAM-1, miR-224, miR-145, and miR-155-5p were evaluated by quantitative real-time polymerase chain reaction (qRT-PCR). The student's t test, chi-square, Mann-Whitney U, and analysis of covariance (ANCOVA) were used for data analyses. RESULTS RIF patients had less endometrial miR-155-5p expression, and higher endometrial and circulating expressions of miR-145 and miR-224 compared to control subjects. Endometrial PECAM-1 and MPP5 expression significantly decreased in patients with RIF compared to the control group. There was a positive correlation between circulating miR-224 and endometrial miR-155-5p, and between circulating miR-155-5p and endometrial PECAM-1 expression levels in patients with RIF. CONCLUSION The present study suggests that circulating miR-224, endometrial miR-145, and PECAM-1 can be reliable, novel biomarkers for diagnosis of RIF.

Abstract
Background: Workers in wastewater treatment plants are exposed to a wide range of chemicals as well as biological contaminants. Objective: To ascertain whether exposure to bio-aerosols under the normal working conditions in wastewater treatment plants is associated with any significant changes in the prevalence of respiratory symptoms and lung function capacities. Methods: 198 employees of wastewater treatment plants and 99 unexposed persons were studied. American thoracic society (ATS) standard respiratory symptom questionnaire was used to determine the prevalence of respiratory symptoms. Pulmonary function tests were conducted for each participant. Results: The prevalence of respiratory symptoms among exposed persons was significantly higher than that of unexposed people. Mean values of most pulmonary function test parameters were significantly lower in the exposed compared to the comparison group persons. Conclusion: Increased prevalence of respiratory symptoms and decrements in pulmonary function test parameters may be attributed to exposure to bio-aerosols released from wastewater treatment plants.

Abstract
The present study was conducted with the aim of studying the comparison of anger management, anxiety and perceived stress in patients with cancer and Coronary Heart Disease (CHD). The two groups of subjects consisted of patients with cancer (n = 120) and patients with CHD (n = 118) who were selected by using a convenience sampling method and by the employment of Spielberger's State-Trait Anger Expression, Costello and Camry Depression and Anxiety scale and Perceived Stress Scale of Cohen, Kamarak and Mermelstein. In order to analyze the data, after the calculation of descriptive statistics and correlation coefficients, MONOVA was employed to test the hypotheses. The findings indicated that patients with CHD regulate the excitement by externalizing anger and patients with cancer control this excitement by internalizing anger. Moreover, stress and depression in patients with CHD were greater than in patients with cancer. The findings were explained by the employment of the theoretical patterns of the mediating role of personality and regulation of excitement in stress and illness.

Abstract
OBJECTIVE Acute coronary syndrome (ACS) is a challenging issue in cardiovascular medicine. Given platelet role in atherothrombosis, we sought to determine whether platelet indices can be used as diagnostic tests for patients who suffered from an acute chest discomfort. METHODS We prospectively enrolled 862 patients with an acute chest pain and 184 healthy matched controls. They were divided into four groups: 184 controls, 249 of non-ACS, 421 of unstable angina (UA), and 192 of myocardial infarction (MI) cases. Blood samples were collected at admission to the emergency department for routine hematologic tests. RESULTS The mean platelet volume (MPV), platelet distribution width (PDW), and platelet large cell ratio (P-LCR) were significantly greater in patients with MI compared with those of non-ACS or control subjects. Negative and significant correlations existed between MPV, PDW, and P-LCR values and platelet count (P < 0.001). Receiver operating characteristic (ROC) curves showed that the MPV, PDW, and P-LCR with cut-off values of 9.15 fL, 11.35 fL, and 20.25% and with area under the curves of 0.563, 0.557, and 0.560, respectively, detected MI patients among those who had chest discomfort. The sensitivities and specificities were found to be 72% and 40%, 73% and 37%, and 68% and 44% for MPV, PDW, and P-LCR, respectively. CONCLUSION An elevated admission MPV, PDW, and P-LCR may be of benefit to detect chest pain resulting in MI from that of non-cardiac one, and also for risk stratification of patients who suffered from an acute chest discomfort.

Abstract
Background Iodine is an important component for the proper function of the thyroid and fetal development. Objective To evaluate the influence of geographic variation on nutritional iodine status during pregnancy. Methods Four hundred eighty-nine women in the first trimester of pregnancy were enrolled. Of these, 419 (85.5%) were from the plain districts and 70 (14.5%) from mountainous regions. Data were obtained on demographic characteristics and accessibility of iodized salt, and samples of table salt were collected. In the third trimester, 322 women remained in the study: 281 (87.2%) from the plains and 41 (12.8%) from the mountainous regions. Salt and urine samples were analyzed for iodine content. Results All participants stated that they used iodized table salt. The proportion of salt samples with optimal iodine content (30 ppm) from the plains and mountain regions were 68.7% and 88%, respectively. The median urinary iodine content (UIC) in the plains area in the first and third trimesters was 82 and 119 μg/L, respectively. The corresponding values in the mountain region were 34.5 μg/L and 76 μg/L. The prevalence of subjects with an inadequate iodine intake (UIC < 150 μg/L) in first and third trimester in the plains and mountain regions were 84.5% and 66.9% vs 98.6% and 90.2%, respectively. Conclusions The prevalence of pregnant women exhibiting UIC < 150 μg/L in the mountain region was substantially higher than those in the plain district. Our findings also show that the current strategy for eradication of iodine deficiency in school-aged children would not fulfill iodine requirements in pregnancy and that additional source(s) of iodine are required to prevent the adverse effects of iodine deficiency in pregnancy. Further studies are needed to address the cause(s) for the rapid depletion of iodine stores in pregnancy.

Abstract
BACKGROUND To assess accessibility of iodinated salt and urinary iodine concentrations (UIC) during pregnancy. This cross-sectional study was carried out between October and December, 2009 in Urmia County, West Azerbaijan (WA), Iran. METHODS Data on demographic characteristics and iodinated salt accessibility were gathered through a questionnaire at 1st trimester. Household salt samples and urine samples (1st -and 3rd trimesters) were analyzed for iodine content. Pregnant women (n=490) at 1st trimester were interviewed. Of these, 490 subjects (12 prenatal care centers) were enrolled. RESULTS All participants declared that they were exclusive users of iodinated salt. Segregation of the household salt samples according to iodine content (0, 8, 15 and 30 ppm) revealed that the respective distributions were 3.3%, 1.4%, 23.7% and 71.6%. Median UIC levels at 1st and 3rd trimesters were 73.5 μg/L and 114μg/L respectively. Accordingly, 86% and 70% of participants exhibited UIC < 150 μg/L. CONCLUSION Median UIC during pregnancy in WA is markedly lower than those previously reported for regions with adequate iodine status in the country. Thus, extra iodine is needed to maintain adequate iodine store during gestation. In addition, this preliminary study reveals that a significant proportion (28%) of the household salt samples had low iodine content (≤ 15 ppm) although a level (>20 and <40 ppm) is mandatory in Iran. Further studies are deemed necessary to elucidate the cause(s) for manifestation iodine deficiency among pregnant women despite 20 years after iodine fortification strategy.

Abstract
OBJECTIVE One of the major problems of all ceramic restorations is their probable fracture against the occlusal force. The aim of the present in-vitro study is was to compare the effect of two marginal designs (chamfer & shoulder) on the fracture resistance of zirconia copings, CERCON (CAD/CAM). MATERIALS AND METHODS This in vitro study was done with single blind experimental technique. One stainless steel dye with 50' chamfer finish line design (0.8 mm depth) was prepared using milling machine. Ten epoxy resin dyes were made, The same dye was retrieved and 50' chamfer was converted into shoulder (1 mm).again ten epoxy resin dyes were made from shoulder dyes. Zirconia cores with 0.4 mm thickness and 35 μm cement Space fabricated on the 20 epoxy resin dyes (10 samples chamfer and 10 samples shoulder) in a dental laboratory. Then the zirconia cores were cemented on the epoxy resin dyes and underwent a fracture test with a universal testing machine (GOTECH AI-700LAC, Arson, USA) and samples were investigated from the point of view of the origin of the failure. RESULT The mean value of fracture resistance for shoulder margins were 788.90±99.56 N and for the chamfer margins were 991.75±112.00 N. The student's T-test revealed a statistically significant difference between groups (P=0.001). CONCLUSION The result of this study indicates that marginal design of the zirconia cores effects on their fracture resistance. A chamfer margin could improve the biomechanical performance of posterior single zirconia crown restorations. This may be because of strong unity and round internal angle in chamfer margin.

Abstract
BACKGROUND Connective tissue diseases (CTDs) are a heterogeneous group of disorders defined by the association of a variety of clinical manifestations with immunologic and other laboratory findings. Overlap of syndromes and aberrant findings appear rather frequently. METHODS Sera of eight antinuclear antibody (ANA) negative, cases of subacute cutaneous lupus erythematosus (SCLE) with antibodies to Ro (SS-A) and a ninth case with clinical and laboratory signs of Sjögren's syndrome and systemic lupus erythematosus (SLE) were tested for complement (C') fixing antinuclear antibodies (C-ANAs). The ninth case was examined in depth by direct immunofluorescence (DIF) and a two-step "C + DIF" test of biopsies for C' fixation to in vivo bound ANAs, as well as serum tests for C-ANA, ANA, and SCLE markers. RESULTS Sera of five of the eight ANA negative, Ro(SS-A) positive SCLE cases had C-ANAs. The ninth case, a 50-year-old woman with clinical and laboratory signs of Sjögren's syndrome and SLE, gave a strong positive C + DIF reaction in the skin biopsy for in vivo bound ANAs that fix C', but negative ANAs and C-ANAs in routine serum tests; they revealed antimitochondrial antibodies. Serum tests on normal skin, however, revealed weak ANA and strong C-ANA reactions with in vitro fixed C'. CONCLUSIONS ANA negative cases of SCLE or Sjögren's syndrome may have C-ANAs. A case with Sjögren's syndrome and signs of SLE had both in vivo and in vitro C' fixing ANAs. C-ANA tests can aid in the identification of such cases.

Abstract
BACKGROUND In 1990 a new disease-associated antinuclear antibody was first recognized as a specific immunologic marker for a chronic form of ulcerative stomatitis (CUS). METHODS Another case is reported herein and the subject of chronic ulcerative stomatitis with stratified epithelium-specific antinuclear antibodies (SES-ANA) is reviewed. Intraoral biopsies from this patient were submitted for microscopic examination and direct immunofluorescence. Indirect immunofluorescence studies were also performed. Serial SES-ANA titers were obtained with the patient on maintenance treatment with hydroxychloroquine. A skin biopsy of a recent lichenoid eruption was obtained and skin explants grown in the serum of this patient were studied in tissue culture with reference to SES-ANA binding and complement fixation. RESULTS Biopsy and serum studies confirmed a diagnosis of CUS with SES-ANA in the patient reported. Skin biopsy showed lichen planus. The patient was treated with hydroxychloroquine with a favorable response. Serial SES-ANA titers did not parallel the disease activity. Among the substantive observations made from skin explants cultured in the serum of this patient was widespread fixation of C3 to the nuclei of basal cells. CONCLUSIONS The case described herein extends the findings in CUS to include lichenoid skin lesions. Records show that at least four of 11 cases of CUS had skin lesions, whereas all had oral lesions. Stratified epithelium-specific antinuclear antibodies serve as the key marker of CUS. Skin explants grown in the serum of this CUS patient bind SES-ANA in tissue culture. Sections of explants fix complement. Titers of SES-ANA have been reported to parallel disease activity in one case, but not in the present case. Thus, there appears to be case-to-case variation. The treatment of choice for CUS is hydroxychloroquine.

Abstract
We evaluated a quantitative reference standard (QRS) slide with 10-microns beads with different concentrations of Coulter Electronics green dye No. 1. Microfluorospectrophotometric readings of the QRS slides provided quantitative comparisons between the sensitivity of the different fluorescence microscopes. The visual comparisons between beads with a range of intensities of fluorescence of Coulter Electronics green dye No. 1 indicated that the end points vary with different optical systems as do the end points in standard indirect immunofluorescent titrations. Fluorescent emission wavelength of QRS slide beads gave the same peak as fluorescein-labeled beads; both differed from the peak of orange beads of an 'Optical Standard' slide. Since shelf life studies show no changes in fluorescence intensity of beads over a period of 27 months or longer, QRS slide beads can afford a device for standardization of fluorescence microscopes used for immunofluorescent tests.
