Abstract
Various studies have shown that natural colorants, in addition to their coloring attributes, have valuable biological effects such as antioxidant, anti-inflammation, and anticarcinogenic properties. Moreover, their use as a food colorant can restrict the potential disadvantages of synthetic additives and turn foods into functional products. In this study, in vitro antimicrobial activities of two natural colorants of bixin and curcumin against some important foodborne pathogens: Staphylococcus aureus (S. aureus), Listeria innocua (L. innocua), and Escherichia coli (E. coli) were investigated by disk diffusion method. Minimum inhibitory concentration and minimum bactericidal concentration values were determined by agar dilution and broth microdilution methods. The synergistic activity of the colorants against selected microorganisms was assayed by the checkerboard microdilution method. The results showed that the inhibitory effects of bixin against S. aureus were more pronounced than E. coli and L. innocua. The lowest concentration of curcumin (0.6 mg/mL) in the disk diffusion method was not inhibited by any tested bacteria. However, it was effective at the higher concentrations against three microorganisms, but its diameter of inhibition zones was lower than gentamicin in all concentrations. Synergetic effects were observed by curcumin and bixin combination against S. aureus (FICI ≤ 0.5), but they act as an antagonist against E. coli and L. innocua. The results of the synergy test were confirmed by the isobologram curves.

Abstract
Today, introducing and evaluating the performance of novel reagents are an undeniable part of designing a successful synthetic strategy. Herein, we study the efficiency and mechanism of recently synthesized nitronium salts (e.g., NO2FSO3, NO2CF3SO3, NO2HS2O7, NO2BF4, NO2PF6, and NO2HSO4) in the oxidation reaction of ethanol to acetic acid, as a model of the primary alcohol transformations to linear carboxylic acid. An aldehyde molecule is the first produced species in this reaction which is converted to the acetic acid molecule in the presence of in situ-produced nitric acid. Concerning the proposed mechanism, among the studied nitronium salts, two different behaviors can be observed in the transition state of the step in which the aldehyde molecule is formed. The calculated barrier energies of this step have been scrutinized by powerful descriptors such as Quantum Theory of Atoms in Molecules (QTAIM), Natural Bond Orbital (NBO), Electrostatic Potential (ESP) surfaces, and Activation Strain Model (ASM). The outcomes of the studied descriptors illustrate that nitronium salts have different performances in progressing the formation of the aldehyde molecule. Indeed, the likeness of the transition state of this step to the products for NO2FSO3, NO2CF3SO3, and NO2HS2O7 species is more significant than the others. Accordingly, these reagents have more potential to apply as oxidizing agents in the primary alcohol transformations to linear carboxylic acid.

Abstract
Abstract
Background
The impact of malnutrition on outcomes in a contemporary ST-segment-elevation myocardial infarction (STEMI) population is unclear. We hypothesized that malnutrition severity amongst STEMI patients undergoing primary percutaneous coronary intervention (pPCI) is associated with worse long-term outcomes.
Purpose
The aim of this study was 2-fold: 1) to establish the prevalence of malnutrition among STEMI patients undergoing pPCI; 2) to determine the association of malnutrition severity on in-hospital and 1-year outcomes in STEMI patients receiving pPCI
Methods
We retrospectively identified 1,169 STEMI patients of age ≥65 years who had received pPCI (2013–2020). Patients who had presented with out-of-hospital cardiac arrest or those who received fibrinolytic therapy were excluded. The Controlling Nutritional Status (CONUT) score, based on serum albumin, total cholesterol and lymphocyte count, was used as a tool to assess the nutritional status of included patients. Malnourished patients were defined as those with a CONUT score of 5 to 12. To account for the impact of frailty, a frailty index (FI) was determined using the health deficit accumulation model (Table 1). The primary outcome was 1-year all-cause mortality. The secondary outcome was a composite of in-hospital heart failure, cardiogenic shock, re-infarction, major bleeding, stroke, and all-cause mortality. A multivariable model adjusting for baseline covariates, including frailty index score, was performed (Figure 1).
Results
Among 1,169 STEMI patients receiving pPCI, 315 (26.9%) were classified as malnourished. Malnourished patients were older (mean 77.4 vs. 76.0 years, p=0.009) and had a higher comorbidity burden. After multivariable adjustment, worsening malnutrition was associated with increased 1-year all-cause mortality (odds ratio [OR] = 1.29, p<0.001). Worsening malnutrition was also associated with a higher incidence of the in-hospital composite adverse outcome (OR = 1.12, p=0.003) and increased in-hospital all-cause mortality (OR=1.41, p<0.001).
Conclusion
Among STEMI patients receiving pPCI, 1 in 4 were malnourished. Malnutrition was associated with increased rate of in-hospital composite adverse outcome and worse long-term outcomes, even when accounting for frailty. Efforts to routinely identify malnourished STEMI patients and to implement best practices to reduce the risk of adverse events in this vulnerable population are warranted.

Abstract
Abstract
Background
The role of cardiac magnetic resonance (CMR) imaging in the diagnostic evaluation of patients with frequent premature ventricular complexes (PVCs) and normal left ventricular ejection fraction (LVEF) remains unclear. Existing data has been predominantly derived from highly selected populations, that may overestimate the true prevalence of abnormal findings on CMR in this patient population.
Purpose
The aim of this study was 2-fold: 1) to establish the prevalence of CMR imaging abnormalities in a cohort with normal LVEF and high PVC burden; 2) to identify predictors of CMR imaging abnormalities in patients with frequent PVCs and normal LVEF.
Methods
In this cohort study, 211 patients (age 53.2±19 years; 41% male) with frequent PVCs (≥5%/24 h), of normal LVEF (≥50% by echocardiography) and no known underlying structural heart disease were prospectively enrolled from 2016–2020. Of these, 166 (79%) patients were symptomatic from their PVCs in the form of palpitations, fatigue, chest pain, dizziness, and/or dyspnea. Patients underwent CMR imaging (1.5 Tesla) with a late gadolinium enhancement (LGE) protocol at the time of enrollment for the detection of scarring and/or fibrosis.
Results
Patients had a median baseline echocardiographic LVEF of 60% (± 5%) with 195 (92%) of patients having a normal native QRS morphology. Median PVC burden of the study cohort was 16% (± 14%). CMR LGE abnormalities were found in 19 (9%) patients including 17 scans with non-ischemic LGE and 2 with ischemic LGE. Age >60 (odds ratio [OR]: 3.20, 95% confidence interval [CI]: 1.20–8.51, p=0.020), male sex (OR: 4.67, 95% CI: 1.61–13.50, p=0.004), history of hypertension (OR: 3.43, 95% CI: 1.31–8.97, p=0.012), native QRS duration (OR: 1.03, 95% CI: 1.00–1.05, p=0.031), and history of non-sustained ventricular tachycardia (OR: 2.81, 95% CI: 1.03–7.68, p=0.044) were significantly associated with the presence of imaging abnormalities on CMR. Dominant PVC origin from the left ventricle had a positive trend (OR: 2.60, 95% CI: 0.99–7.66, p=0.083) to association with CMR imaging abnormalities. On multivariate analysis, male sex (OR: 4.10, 95% CI: 1.40–12.04, p=0.010) and history of hypertension (OR: 2.89, 95% CI: 1.08–7.75, p=0.035) remained significantly associated with the presence of CMR abnormalities. There was no association between CMR imaging abnormalities and the burden of PVCs or the number of PVC morphologies.
Conclusion
In this cohort, only 9% of patients with apparently idiopathic frequent PVCs and normal LVEF had concealed myocardial abnormalities on CMR imaging. Male sex and history of hypertension were associated with a higher rate of CMR abnormalities.

Abstract
Abstract
Background
South Asians (SA) have an increased prevalence of coronary artery disease (CAD) and myocardial infarction compared with age- and sex-adjusted White Caucasians (WC). The mechanism for this increased risk is poorly understood. While classical CD14++CD16- monocytes act as independent predictors of cardiovascular disease, differences in the distribution of monocyte subsets between SA and WC have not been established.
Purpose
We aimed to determine if differences exist in monocyte subsets between SA and WC at risk for CAD.
Methods
Our cohort consisted of 119 consecutively enrolled patients (59 SA, 60 WC) at intermediate or higher risk for CAD by the INTERHEART score using self-reported history and physical exam. A single blood sample was collected prospectively for the purpose of monocyte analysis. Flow cytometry using dual colour fluorescence (CD14, CD16) within the monocyte gate was used to identify monocyte subsets (classical, intermediate and non-classical) by staff blinded to the individuals' characteristics.
Variables were compared using Mann-Whitney U test and Chi-squared test, as appropriate. Eta coefficient was calculated to analyze the relationship between ethnicity and proportion of monocyte subsets. Eta squared values were calculated to assess the impact of ethnicity on monocyte subset proportions.
Results
The SA group consisted of 64% males with a mean age of 54 (± 9), while the WC group consisted of 55% males with a mean age of 59 (± 7). Both groups had similar body mass index, rates of hypertension, dyslipidemia and family history of premature CAD. Compared to WC, SA had higher prevalence of diabetes (36% vs. 13%, p=0.005) and hemoglobin A1C levels (6.0±1.1% vs. 5.6±0.6%, p<0.001). SA patients had a higher proportion (85.3±10.7% vs. 81.4±11.0%, p=0.009) and total level (449.0±180.4 vs. 388±127.4, p=0.010) of classical CD14++CD16- monocytes compared to WC. There was no difference between the two groups in the proportion of intermediate CD14++CD16+ and non-classical CD14+CD16++ monocytes. There was no association between diabetes and the proportion of monocyte subsets. Ethnicity had a moderate association with the proportion of classical CD14++CD16- monocytes (Eta coefficient = 0.525) with a large effect size (Eta squared = 27.5%). The association of ethnicity with intermediate CD14++CD16+ and non-classical CD14+CD16++ monocytes was either weak or negligible with minimal to no effect size.
Conclusion
In patients with substantive risk for CAD, SA had a significantly higher proportion and level of classical CD14++CD16- monocytes compared to WC. Our findings provide a novel insight into the potential mechanism of increased CAD susceptibility amongst SA compared to WC. Future studies are needed to determine whether these ethnic differences in the distribution of monocyte subsets can predict susceptibility to developing CAD and suffering atherothrombotic events.

Abstract
BACKGROUND Musculoskeletal disorders are very prevalent among dentists. Of these disorders, carpal tunnel syndrome (CTS) is notable. OBJECTIVE The aim of this study was to investigate the relationship between the occupational and non-occupational risk factors and CTS among dentists. METHODS It is a cross-sectional study. We evaluated 106 dentists from dental schools in Tehran. We collected data by a general questionnaire, a hand diagram, and physical examination. A nerve conduction velocity (NCV) test was used to confirm the diagnosis of CTS. The analysis was performed using an independent T-test and logistic regressions on SPSS software. RESULTS The prevalence of CTS among dentists was 17.9%. Significant risk factors of CTS included: vibration exposure greater than two hours per day (OR: 2.5), a wrist diameter ratio of greater than 0.7 (OR: 10.14), and female sex (OR: 13.38). CONCLUSIONS Exposure to the hand-arm vibration should be considered as an occupational risk factor for CTS in dentists. Female dentists should take more preventive measures.

Abstract
Leiomyomas are benign lesions of the uterine smooth muscles that contain various amounts of fibrous connective tissue. Hystrosalpingography is not a method of diagnosing uterine fibroids, and other methods such as ultrasound and MRI are preferred, but during hystrosalpingography, especially in infertile females, uterine fibroids may be seen frequently. Leiomyomas have a wide range of appearances depending on their number, size and location. Leiomyomas may enlarge, elongate, displace, distort or rotate the uterine cavity and can be detected by such changes showing in hysterosalpingograms. These changes may be symmetric or asymmetric. Leiomyomas may result in uterine atony which can be locolized or generalized. Leiomyomas also may appear as one or multiple filling defects in different sizes which can be smooth or irregular. Some of the noted findings may create similar and frequent appearances looking like some patterns in nature and can be considered "excellent signs" for better detecting and enabling differential diagnosis. This study aims to improve the process of training on the diagnostic appearances of leiomyomas in hysterosalpingography by aligning the images with patterns found in nature that can be easily remembered by radiologists.

Abstract
In vitro antimold activity of annatto natural dye against Aspergillus niger, Neurospora sitophila, and Rhizopus stolonifer was evaluated with agar well diffusion and agar dilution assays. The effects of adding annatto dye (0, 0.5, 0.75, and 1%) to bread formulations were then examined. Total microbial and fungal counts, moisture, color, radical scavenging activity, and sensory analysis of bread were monitored. A. niger was the fungus most sensitive to annatto dye in vitro. Increased dye concentrations resulted in significant decreases ( P < 0.05) in moisture, total microbial and fungal counts, and L*, a*, and b* values of bread. The highest antioxidant activity was achieved in the bread with 1% of annatto dye. All bread containing annatto dye had acceptable sensory attributes as determined by panelists. The addition of annatto dye resulted in bread with a longer shelf life and acceptable sensory qualities.

Abstract
BACKGROUND Angiogenesis initiated by cancerous cells is the process by which new blood vessels are formed to enhance oxygenation and growth of tumor. OBJECTIVE In this paper, we present a new multiscale mathematical model for the formation of a vascular network in tumor angiogenesis process. METHODS Our model couples an improved sprout spacing model as a stochastic mathematical model of sprouting along an existing parent blood vessel, with a mathematical model of sprout progression in the extracellular matrix (ECM) in response to some tumor angiogenic factors (TAFs). We perform simulations of the siting of capillary sprouts on an existing blood vessel using finite difference approximation of the dynamic equations of some angiogenesis activators and inhibitors. Angiogenesis activators are chemicals secreted by hypoxic tumor cells for initiating angiogenesis, and inhibitors of the angiogenesis are chemicals that are produced around every new sprout during tumor angiogenesis to inhibit the formation of further sprouts as a feedback of sprouting in angiogenesis. Moreover, for modelling sprout progression in ECM, we use three equations for the motility of endothelial cells at the tip of the activated sprouts, the consumption of TAF and the production and uptake of Fibronectin by endothelial cells. RESULTS Coupling these two basic models not only does provide a better time estimation of angiogenesis process, but also it is more compatible with reality. CONCLUSION This model can be used to provide basic information for angiogenesis in the related studies. Related simulations can estimate the position and number of sprouts along parent blood vessel during the initial steps of angiogenesis and models the process of sprout progression in ECM until they vascularize a tumor.

Abstract
Many studies have showed the role of androgens on ovarian follicular maturation. The present study investigated the effect of serum concentration of androgens, LH, and insulin-like growth factor 1 (IGF1) in the early follicular phase on the results of the ovulation induction (I/O) and intrauterine insemination (IUI) cycles. This cross-sectional study was done in the infertility clinic of Akbar Abadi hospital. Fifty-nine infertile patients who were not affected by polycystic ovary syndrome (PCO) and were candidates for induction ovulation or intrauterine insemination were chosen at random. The serum concentrations of androgens (free testosterone, dihydroepiandrosterone, and androstenedione), LH, and IGF1 were measured on the third day of menstruation. Sonographic monitoring was started from the ninth day of the cycle. The ampule of hCG was injected when there was at least one follicle with the diameter of 18 mm. The relationships of concentration of androgens, LH, and IGF1 with follicular growth parameters and pregnancy rate were analysed. There was no statistically significant link between the number and diameter of follicles with concentration of free testosterone, dihydroepiandrosterone, androstenedione, IGF1, and LH. There was no statistically significant link between the number of follicles in the ovaries and concentrations of testosterone (P = 0.090 and r = 0.223), dihydroepiandrosterone (P = 0.642 and r = 0.062), androstenedione (P = 0.526 and r = 0.084), IGF1 (P = 0.470 and r = 0.096), and LH (P = 0.446 and r = 0.102). There was no statistically significant link between the mean follicular diameter and concentration of testosterone (P = 0.822 and r = 0.03), dihydroepiandrosterone (P = 0.733 and r = 0.045), androstenedione (P = 0.526 and r = 0.084), IGF1 (P = 0.799 and r = 0.034), and LH (P = 0.626 and r = 0.065). Beta human chorionic gonadotropin (β-hCG) was positive in 11 patients (18.6%) and negative in 48 patients (81.4%). Serum concentrations of androgen profile, LH, and IGF1 in the positive (β-hCG) group were not significantly different in comparison with the negative β-hCG group. It seems that in women who were not affected by PCO, concentrations of free testosterone, dihydroepiandrosterone, androstenedione, IGF1, and LH in the early follicular phase were not related to follicular growth parameters and pregnancy rate.

Abstract
The active substance of turmeric rhizome (curcumin) was extracted and identified with TLC and NMR. To evaluate the antioxidant efficiency of different concentrations of curcumin (120, 160 and 200 ppm) compared with tert-butylhydroquinone (TBHQ) (120 ppm) and α-tocopherol (200 ppm) at two different temperatures (25°C and 55°C) under dark and light conditions during 90 days, the soybean oil with no added antioxidant was used as a food model, and its fatty acids profile was determined by GC. Results indicated that increasing concentration of curcumin leads to significantly decreased oxidation rates. The soybean oil containing curcumin at 25°C in darkness with the lowest rate of increased peroxide value indicated the same antioxidant activity with α-tocopherol and TBHQ. Moreover, the results of acid value and iodine value indicated that samples with curcumin were more effective in preventing oxidation at both temperatures compared with control. However, light did not have any significant effect.

Abstract
BACKGROUND Toxoplasma gondii infects a wide range of animals; felines are definitive hosts and other animals including the dogs are intermediate hosts. The aim of this study was to determine the seroprevalence of T. gondii infection in dogs in Tehran, capital of Iran and to investigate possible associated risk factors. METHODS Three hundreds ninety six serum samples were collected during 2007-8 from the dogs. Collected samples were tested using an indirect fluorescent antibody test (IFAT) in dilutions of 1:16 and more. All procedures were carried out in Shahrekord University, Iran. All the data were analyzed using SPSS software, qui square test with confidence interval of 0.95. RESULTS From evaluated samples, 89 (22.47%) were positive in titers of at least 1:16. further evaluations in other dilutions showed positive results in dilutions of maximum 1:16, 1:32, 1:64, 1:128 and 1:256 in 38, 29, 15, 2 and 5 dogs respectively. Investigation of the role of risk factors showed no sex predisposition while infection rate was significantly higher in dogs older than one year old. Living places were of significant importance; infection rate was significantly higher in stray or guard dogs in compare with household dogs (P<0.05). CONCLUSION Relatively high seroprevalence of T. gondii infection in dogs in Tehran shows high environmental contamination. It is recommended that the dogs with suspected clinical signs be tested for T. gondii infection.

Abstract
Renal ischemia/reperfusion injury is a major cause of acute renal failure. The production of free radicals and reactive oxygen species are important factors contributing to ischemia/reperfusion injury. Thus, scavenging of the excess free radicals can be an important therapeutic approach. The present study examined the protective effect of beta carotene against renal ischemia/reperfusion injury in rat. Male adult Wistar rats (250-300 g) were exposed to 45 min of renal ischemia followed by 4 h of reperfusion. Beta carotene (10, 30 and 100 mg kg(-1)) or vehicle was administered for 5 days prior to ischemia. Renal function was assessed by plasma and urinary analysis. Present results showed that ischemia/reperfusion injury increased (p < 0.05-p < 0.001) serum urea and creatinine levels, as well as urinary excretion of protein and calcium and fractional excretion of sodium, while decreased glomerular filtration rate and potassium excretion. However, alterations in these biochemical indices due to ischemia/reperfusion injury were attenuated by beta carotene pretreatment (p < 0.05-p < 0.001), although not by all doses. Since, beta carotene administration improved renal function, it seems that beta carotene protects renal tissue against ischemia/reperfusion-induced oxidative damage.

Abstract
A 4-year-old female Persian cat was referred with the history of separation from the owner. There was no clinical sign and everything had been reported as normal during the veterinary checkup just before separation and traveling. The history and clinical signs were fit to separation anxiety when the cat referred to us. Ten days after the diagnosis and starting of the treatment for separation anxiety, the cat was referred again with the clinical signs of chronic renal failure. Further assessments showed an inherited polycystic kidney disease. Spontaneous manifestation of polycystic kidney disease after separation anxiety indicate that this phenomenon may cause the chronic process of polycystic kidney disease to promote.

Abstract
1. Generically based pharmaceutical systems exist in a few countries of the world, such as Iran. Most developed countries have free market pharmaceutical systems. Drug-related problems (DRP) have been reported mostly in the Western world but few data are available for generic systems. In this study, we tried to measure the prevalence of drug-related problems leading to hospital admissions in Isfahan, Iran. 2. One thousand consecutive hospital admissions in three major teaching hospitals were studied for a period of 6 months for the presence of DRP as a cause of hospital admissions. Two subcategories of DRP were considered: (i) drug therapy failure; and (ii) adverse drug reactions. Preventability and outcome measures were also assessed. Medications responsible for DRP were classified according to the Anatomic Therapeutic Chemical (ATC) classification of the World Health Organization. 3. Of the 1000 admissions studied, 115 (11.5%) were owing to DRP, 81% as a result of drug therapy failure and 19% as adverse drug reactions. A total of 106 out of the 115 DRP cases (92%) were either preventable or probably preventable, most of which had to do with either prescriber or patient error. An overview of DRP showed that 58.3% resulted in complete recovery, 33.9% in relative recovery and 7.8% in death. Close to 1% of hospital admissions resulted in DRP-related deaths. 4. The overall prevalence of hospital admissions caused by DRP is similar to that in free market pharmaceutical systems. The high preventability rate of these problems should alert clinicians and policy makers to design strategies to curtail this. Also, reasons for differences in subtypes of DRP between the results of this study and those of the literature from free market systems needs to be investigated further.
