Abstract
Chronic kidney disease (CKD) is commonly associated with unfavorable cardiovascular outcomes and remains the leading cause of mortality in individuals with end-stage renal disease (ESRD). Despite substantial knowledge about the impact of CKD on the left heart, the right heart, which holds significant clinical relevance, has often been overlooked and inadequately assessed in ESRD patients who have undergone kidney transplant (KTx). This study aimed to evaluate the effects of KTx on the right heart chambers in ESRD patients. 57 adult KTx candidates were enrolled in this prospective longitudinal study, while 49 of them were included in the final assessment. Patients underwent a comprehensive cardiac assessment, including conventional echocardiography, speckle tracking echocardiography, and three-dimensional heart modeling both before and after surgery. Echocardiographic assessments showed significant increases in right ventricular (RV) ejection fraction, RV fractional area change (RVFAC), tricuspid annular plain systolic excursion, RV fractional shortening, right atrial (RA) reservoir, conduit, and booster strains, and RV global longitudinal strain (RVGLS). Moreover, significant reductions in RV end-diastolic volume (RVEDV), RV end-systolic volume (RVESV), RV stroke volume, RV end-diastolic diameter (RVEDD) in mid-cavity view, systolic pulmonary artery pressure was observed (all P values < 0.05). However, no significant difference was found in S velocity, as well as RVEDD in basal and apex-to-annulus view. Moreover, pre-KTx measurements of RVGLS, RVEDD (apex-to-annulus diameter), RV fractional shortening, and S velocity were predictors of RVGLS after KTx. RA conduit strain was also identified as a predictor of RA conduit strain after KTx. Additionally, age, RVEDV, RVESV, RVFAC, and RA reservoir strain before KTx were identified as independent predictors of RA reservoir strain after KTx. The findings of this study demonstrate a significant improvement in right heart function following KTx. Furthermore, strain analysis can provide valuable insights for predicting right heart function after KTx.

Abstract
The role of inflammation has been proven in acute myocardial infarction (AMI) pathogenesis. Due to the effect of NLRP3 gene expression in the inflammation process of MI, we aimed to explore the expression changes and diagnostic power of four inflammation-related miRNAs including miR-17-3p, miR-101-3p, miR-335-3p, miR-296-3p and their potential target, NLRP3, in ST-segment elevation myocardial infarction (STEMI), and non-STEMI (NSTEMI) patients as two major classes of AMI. The expression level of these genes were evaluated in 300 participants equally divided into three groups of STEMI, NSTEMI, and control using quantitative real-time PCR. The expression level of NLRP3 was upregulated in STEMI and NSTEMI patients compared to control subjects. Besides, the expression levels of miR-17-3p, miR-101-3p, and miR-296-3p were significantly downregulated in STEMI and NSTEMI patients compared to controls. The increased expression of NLRP3 had a very strong inverse correlation with miR-17-3p in patients with STEMI and with miR-101-3p in the STEMI and NSTEMI patients. ROC curve analysis showed that the expression level of miR-17-3p had the highest diagnostic power for discrimination between STEMI patients and controls. Remarkably, the combination of all markers resulted in a higher AUC. In summary, there is a significant association between the expression levels of miR-17-3p, miR-101-3p, miR-335-3p, miR-296-3p, and NLRP3 and the incidence of AMI. Although the miR-17-3p expression level has the highest diagnostic power to distinguish between STEMI patients and control subjects, the combination of these miRNAs and NLRP3 could serve as a novel potential diagnostic biomarker of STEMI.

Abstract
Background To define changes in AMI case rates, patient demographics, cardiovascular comorbidities, treatment approaches, in-hospital outcomes, and the economic burden of COVID-19 during the pandemic. Methods We conducted a multicenter, observational survey with selected hospitals from three medical universities in Tehran city. A data collection tool consisting of three parts. The first part included socio-demographic information, and the second part included clinical information, major complications, and in-hospital mortality. Finally, the third part was related to the direct medical costs generated by AMI in COVID-19 and non-COVID-19 patients. The study cohort comprised 4,560 hospitalizations for AMI (2,935 for STEMI [64%] and 1,625 for NSTEMI [36%]). Results Of those hospitalized for AMI, 1,864 (76.6 %) and 1,659 (78 %) were male before the COVID-19 outbreak and during the COVID-19 era, respectively. The length of stay (LOS), was significantly lower during the COVID-19 pandemic era (4.27 ± 3.63 vs 5.24 ± 5.17, p = 0.00). Results showed that there were no significant differences in terms of patient risk factors across periods. A total of 2,126 AMIs were registered during the COVID-19 era, with a 12.65 % reduction (95 % CI 1.5-25.1) compared with the equivalent time in 2019 (P = 0.179). The risk of in-hospital mortality rate for AMI patients increased from 4.9 % in 2019 to 7.0 % in the COVID-19 era (OR = 1.42; 95 % CI 1.11-1.82; P = 0.004). Major complications were registered in 9.7 % of cases in 2020, which is higher than the rate of 6.6 % reported in 2019 (OR = 1.46, 95 % CI 1.11-1.82; P = 0.000). Total costs in hospitalized AMI-COVID patients averaged $188 more than in AMI patients (P = 0.020). Conclusion This cross-sectional study found important changes in AMI hospitalization rates, worse outcomes, and higher costs during the COVID-19 periods. Future studies are recommended to examine the long-term outcomes of hospitalized AMI patients during the COVID-19 era.

Abstract
Background: Macrophage inhibitory cytokine 1-Growth differentiation Factor 15 (MIC-1/GDF15) and vascular endothelial growth factor (VEGF) are novel regulators of obesity and energy homeostasis and food intake. Aims: In the current cross-sectional study, we aimed to evaluate MIC-1 and VEGF concentrations and their association with serum lipids and biomarkers of oxidative stress in obese individuals. Methods: Fifty six obese subjects, aged between 20-50 years old, participated in the current study. Anthropometric and nutritional parameters were assessed and serum and blood concentrations of MIC-1/GDF15, VEGF, markers of oxidative stress and serum lipids were evaluated. Results: Serum VEGF was strongly associated with serum lipids and MIC-1/GDF15 concentrations while serum MIC-1/GDF15 was associated with total cholesterol (TC) and VEGF levels. In multivariate regression analysis, serum VEGF, appetite and GPX were potent determinants of MIC-1/GDF15 concentrations while VEGF was only associated with serum MIC-1/GDF15. Conclusion: The findings of the current study demonstrated the association between MIC-1/GDF15 and VEGF. Moreover, a positive association between these cytokines and serum lipids, was also observed. The results suggest that MIC-1/GDF15 and VEGF might be considered as prognostic markers in obesity-related metabolic disorders. Although further mechanistic studies are needed to better clarify the underlying mechanism.

Abstract
BACKGROUND Nonbacterial thrombotic endocarditis is a rare complication of prothrombotic states such as neoplasms that can cause valvular dysfunction and life-threatening complications. Nonbacterial thrombotic endocarditis usually affects the left-sided valves; however, only a minority of cases involving the tricuspid valve have been reported in medical literature. CASE PRESENTATION The current report describes trivalvular involvement by nonbacterial thrombotic endocarditis in a 54-year-old Azeri female patient with metastatic colorectal carcinoma. This case underlines the necessity of evaluating nonbacterial thrombotic endocarditis as a possible consequence in cancer patients. When thromboembolic events are found in the presence of a hypercoagulable state (such as malignancy) and no growth on blood cultures, nonbacterial thrombotic endocarditis could be suspected as the cause. CONCLUSION It is critical to achieve early diagnosis in such a setting to initiate treatment plans and prevent further complications rapidly.

Abstract
The dietary cation-anion difference (DCAD) has gotten much attention recently; however, there is not much evidence on organic matter digestibility, blood parameters, dry matter intake, body weight, and carcass features of male sheep fed with different DCAD diets. The effects of dietary cation-anion difference (DCAD) on these traits in male lambs under the environmental high temperatures were investigated in this study. Forty male lambs (average body weight of 39 kg) were randomly assigned to one of five treatments with eight replicates. Lambs were fed diets with DCAD levels ranging from 150 (control group) to 300, 450, 600, and 750 mEq/kg dry matter. This study lasted 100 d and used a 21-d adaptation. The results showed that the control group had the highest dry matter intake, dry matter digestibility, and crude protein digestibility (P = 0.02). Also, the lowest amount of average body weight was observed in the control group (P = 0.01). The results showed the different DCAD levels affected the statistical significance in terms of live weight, carcass weight, length and width of muscle cross section, lung weight, spleen weight, and abdominal fat (P = 0.04). As well, the highest ruminal pH was observed in the control group (P = 0.4). The results of the blood glucose parameter showed that control group had a significant effect on the blood glucose level (P = 0.04). Furthermore, the highest abdominal fat weight was observed in the control group (P = 0.04). There was no statistically significant difference between other traits, including skin weight, head weight, leg weight, carcass length, liver weight, kidney weight, heart weight, testicle weight, tail weight, rumen weight, and lactation weight. In summary, increasing DCAD in the diet could improve the production and carcass quality in lambs under environmental high temperatures.

Abstract
BACKGROUND The association of obesity with left ventricular (LV) diastolic dysfunction is fully understood, but there are few investigations regarding its effect on LV systolic function in the absence of other risk factors. This study aimed to identify the global longitudinal strain (GLS) changes in isolated overweight and obese people in the absence of other risk factors. METHODS A total of 120 individuals, including 60 obese, 30 overweight, and 30 healthy controls with no underlying disease and no history of hypertension, diabetes, CAD, or CKD were included in the study. Echocardiographic findings were measured, including apical 2-, 3- and 4-chamber GLS, GLS total, LV diameter, interventricular septum thickness, and PAP. These findings were then compared between the three groups (obese, overweight, and normal controls). RESULTS Analyses showed that LV diameter in healthy controls was significantly lower compared to overweight (p = 0.02) and obese (p < 0.0001) participants. Also, the interventricular septal thickness was significantly increased in overweight (p = 0.007) and obese (p < 0.0001) individuals compared to healthy controls. The mean and standard deviation (Mean ± SD) of total GLS values were - 22.29% ± 1.89% for normal weight, -22.09% ± 1.91% for overweight, and -19.88% ± 2.34% for obese individuals. The total GLS of obese participants was significantly lower than overweight and normal controls (p < 0.0001). It was observed that the GLS values were significantly lower in people with BMI higher than 40. The mean ± SD of total GLS values were -20.68% (1.84%) for BMI ≤ 40 patients and -18.51% (2.52%) for BMI > 40 patients. CONCLUSION Data revealed that all GLS values had a moderately strong correlation with BMI values. Also, subclinical LV dysfunction was detected in overweight and obese subjects.

Abstract
Tricuspid valve myxomas are very uncommon tumors that could be found after the occurrence of pulmonary thromboembolism, symptomatic tricuspid obstruction, and right-sided heart failure. Herein, we describe a 42-year-old woman evaluated for an abdominal mass. In preoperative consultation, a tricuspid valve mass was detected in echocardiography. She underwent the removal of a benign uterine myoma and a myxoma of the tricuspid valve. Tricuspid valve myxomas constitute a scarce diagnosis. They could be asymptomatic, occurring in unusual locations and in association with benign tumors in other organs. Our patient was asymptomatic, underscoring the significance of the early diagnosis of this type of tumor to prevent further catastrophic events.

Abstract
Aortic dissection is an infrequent diagnosis that usually presents with acute onset of sharp and severe tearing pain. It rarely presents with atypical symptoms, accompanied by a higher mortality risk that arises the delay in diagnosis. In this report, we discuss a type A aortic dissection case with a presentation of heaviness-like chest pain with no evidence of aortic dissection in his first echocardiography. The patient was treated for acute coronary syndrome (ACS), but on the follow-up, echocardiography aortic dissection was diagnosed accidentally. Differentiation between ACS and aortic dissection is critical in patient management. Each one has an entirely different treatment approach, and misdiagnosis can lead to catastrophic outcomes.

BACKGROUND Recent reports have indicated the beneficial role of strain measurement in COVID-19 patients. HYPOTHESIS To determine the association between right and left global longitudinal strain (RVGLS, LVGLS) and COVID-19 patients' outcomes. METHODS Hospitalized COVID-19 patients between June and August 2020 were included. Two-dimensional echocardiography and biventricular global longitudinal strain measurement were performed. The outcome measure was defined as mortality, ICU admission, and need for intubation. Appropriate statistical tests were used to compare different groups. RESULTS In this study 207 patients (88 females) were enrolled. During 64 ± 4 days of follow-up, 22 (10.6%) patients died. Mortality, ICU admission, and intubation were significantly associated with LVGLS and RVGLS tertiles. LVGLS tertiles could predict poor outcome with significant odds ratios in the total population (OR = 0.203, 95% CI: 0.088-0.465; OR = 0.350, 95% CI: 0.210-0.585; OR = 0.354, 95% CI: 0.170-0.736 for mortality, ICU admission, and intubation). Although odds ratios of LVGLS for the prediction of outcome were statistically significant among hypertensive patients, these odds ratios did not reach significance among non-hypertensive patients. RVGLS tertiles revealed significant odds ratios for the prediction of mortality (OR = 0.322, 95% CI: 0.162-0.640), ICU admission (OR = 0.287, 95% CI: 0.166-0.495), and need for intubation (OR = 0.360, 95% CI: 0.174-0.744). Odds ratios of RVGLS remained significant even after adjusting for hypertension when considering mortality and ICU admission. CONCLUSION RVGLS and LVGLS can be acceptable prognostic factors to predict mortality, ICU admission, and intubation in hospitalized COVID-19 patients. However, RVGLS seems more reliable, as it is not confounded by hypertension.

Abstract
The objectives were to compare the effectiveness of poultry by-product meal (PBM) with xylose-treated soybean meal (x-SBM) as a conventional protein source and rumen-undegraded protein (RUP):rumen-degraded protein (RDP) ratio on nutrient digestibility, nitrogen metabolism, and production of early- to mid-lactation Holsteins. Twelve multiparous cows averaging (mean ± SD) 50 ± 9 days in milk were randomly assigned to a replicated 4 × 4 Latin square design within a 2 × 2 factorial arrangement of treatments. Each period was 28 days in length. Treatments were RUP sources (PBM or x-SBM) with either a high or a low RUP:RDP ratio (high ratio = 40:60 or low ratio = 36:64; based on % of crude protein (CP)). Experimental diets were balanced to be similar in protein and energy contents (CP = 16.7% of DM; NEL = 1.67 Mcal/kg DM). Prior to diet formulation, an in situ pilot experiment was conducted to estimate the RUP fractions of x-SBM and PBM as 63.9% and 54.1% of CP, respectively. Treatments had no effect on ruminal pH and total volatile fatty acid (VFA) and molar percentage of individual VFAs. Treatments had no effect on total tract apparent digestibility of DM, OM, and neutral detergent fiber (NDF), with the exception of N that was greater in diets with a low RUP:RDP ratio (68.2 vs. 70.1% of DM). DM consumption was 0.70 kg/day higher when cows were fed PBM diet compared with x-SBM diet. No treatment effect was observed on milk yield and milk composition; however, milk protein yield and milk urea N were greater in cows fed PBM. Inclusion of PBM in the diet in substitution to x-SBM resulted in increased blood levels of urea N, cholesterol, and non-esterified fatty acid (NEFA). There was no interaction between the RUP source and the RUP:RDP ratio for urinary and fecal N excretion. Efficiency of N utilization expressed as milk N secretion as a proportion of N intake tended to be greater in cows fed PBM. Feeding diets with a low ratio of RUP:RDP increased efficiency of milk production expressed as milk yield as a proportion of total N excretion (fecal and urinary N). Feeding a diet with PBM supported milk production comparable with x-SBM and had positive effects on feed intake, milk protein yield, and milk N efficiency.

Abstract
Double orifice mitral valve is a rare condition and may be accompanied by a bicuspid aortic valve (sometimes normal functioning) and coarctation of the aorta. Echocardiography is valuable in detecting the accompanied anomalies. Management depends on the severity of mitral valve function and the severity of associated anomalies.

Abstract
Heat stress is a major problem for dairy cows in hot climates, thus coping strategies are essential. This study evaluated the effects of increasing diet fermentability on intake, total tract digestibility, ruminal pH and volatile fatty acids (VFA) profile, blood metabolite profile and milk production and composition of lactating dairy cows managed under conditions of ambient heat stress. Nine multiparous cows (650 ± 56 kg BW; mean ± SD) averaging 102 ± 13 days in milk and producing 54 ± 6 kg/day were randomly assigned to a triplicate 3 × 3 Latin square. During each 21-day period, cows were offered one of three total mixed rations that varied in diet fermentability. The three levels of diet fermentability were achieved by increasing the proportion of pellets containing ground wheat and barley in the dietary DM from 11.7% (low), to 23.3% (moderate), and 35.0% (high) by replacing ground corn grain. Each period had 14 day of adaptation and 7 day of sampling. The ambient temperature-humidity index ( ≥ 72) indicated that the cows were in heat stress almost the entire duration of the study. Also, rectal temperature of cows was elevated at 39.2°C, another indication of heat stress. Increasing diet fermentability linearly decreased dry matter intake (22.8, 22.5, 21.8 kg/day for low, moderate and high, respectively; P ≤ 0.05) but increased non-fibre carbohydrate digestibility (P ≤ 0.05) and tended to increase digestibility of DM (P = 0.10) and crude protein (P = 0.06). As a result, the intake of digestible DM was not affected by the treatments. The production of 3.5% fat corrected milk (32.6, 33.7, and 31.5 kg/day) was quadratically (P ≤ 0.05) affected by diet fermentability with lower production for the high diet compared with the other two, which were similar. Rumen pH (ruminocentesis) and proportions of butyrate and isovalerate linearly decreased whereas propionate proportion linearly increased with increasing diet fermentability (P ≤ 0.05). The rumen concentration of NH3-N (11.0, 9.0, and 8.7 mg/dL) and blood concentration of urea linearly decreased with increasing diet fermentability (P ≤ 0.05). The activity of alkaline phosphatase increased (65.1, 83.2, and 84.9 U/l) and concentration of malondialdehyde decreased (2.39, 1.90 and 1.87 µmol/l) linearly with increasing diet fermentability (P ≤ 0.05), which indicated possible attenuation of the effects of oxidative stress with increasing diet fermentability. Overall, a modest increase of diet fermentability improved nitrogen metabolism, milk protein production and oxidative stress of heat-stressed dairy cows, but a further increase in diet fermentability decreased milk yield.

Abstract
Blood cysts in the heart are often incidentally found during post-mortem examinations in infants, and usually do not cause clinical symptoms. They almost always regress spontaneously, and only a few cases of embolization or valvular dysfunction have been reported previously. We report a 62-year-old man who presented with chest discomfort and dyspnea on exertion for several years, and was found to have a dynamic murmur in left ventricular outflow tract (LVOT) on physical examination. His echocardiogram demonstrated two large blood cysts attached to the subvalvular apparatus of mitral valve, causing significant LVOT obstruction and mild to moderate mitral regurgitation. The cysts were surgically excised and pathology confirmed simple blood cysts. <Learning objective: To the best of our knowledge, this is the first reported case of twin blood cysts with severe left ventricular outflow tract obstruction in an adult, since most of these cysts either regress spontaneously in childhood or remain asymptomatic in adults.>.

Abstract
Patent foramen ovale (PFO) is usually asymptomatic; however, it could be quite dangerous for patients with right side clot in which thrombus can transmit the PFO and paradoxically emboli to systemic circulation. Here we present a patient with ankle fracture and paradoxical embolus to the brain, who was successfully treated with emergent thrombectomy, inferior vena cava (IVC) filter placement and anticoagulation therapy. Despite the high rate of mortality in these patients, fortunately our patient survived with surgical treatment.

Abstract
BACKGROUND Right ventricle function significantly decreases after coronary artery bypass surgery; as one of the likely causes, such a condition is attributed to the use of cardiopulmonary pump (CPB). Because nowadays there is a tendency toward increasing use of off-pump coronary artery bypass (OPCAB) surgery, this study was conducted to evaluate the right ventricle function after this type of surgery using strain and strain rate imaging (SRI) echocardiography. METHODS This study was conducted on 30 patients, candidate for elective OPCAB surgery, between 2011 and 2012. Standard echocardiography was performed before the surgery and the right ventricle function was examined using strain and SRI echocardiography. Then patient underwent surgery, 6 days and 3 months after surgery they underwent echocardiography again and the results obtained from the three stages were compared with each other. RESULTS Participants included 30 patients (23 males and 7 females) with a mean age of 66±11 years. Compared to the prior of the surgery, 6 days and 3 months after the surgery there was a significant decrease in tricuspid annular plane systolic excursion (TAPSE), tissue Doppler imaging (TDI) at the lateral annulus of tricuspid valve, and strain and SRI of right ventricle. However, the values obtained 3 months after surgery were significantly higher than those obtained after 6 days. In other words, the right ventricle function 6 days after the surgery had dropped, however some of the values recovered 3 months after the surgery. CONCLUSIONS The findings of this study are consistent with other studies in this field and showed that after coronary artery surgery a decline occurs in right ventricular function. However, more detailed quantitative strain and SRI parameters which were measured in our study showed that at the early days after the OPCAB surgery there is a decline in the right ventricle function which is relatively reversible at longer intervals (3 months after surgery).

Abstract
Double-orifice mitral valve is a rare congenital anomaly that usually does not cause a significant hemodynamic effect. Double-orifice mitral valve and a bicuspid aortic valve were detected in a 54-year-old lady who presented with dyspnea on exertion for one year. This is a rare association. Three-dimensional echocardiography is helpful to determine the type of malformation. The patient had no significant mitral regurgitation or stenosis, but demonstrated moderate aortic stenosis. She is undergoing periodic monitoring.

Abstract
Asymptomatic pediatric pulmonic valve myxoma involving the right ventricular out flow tract (RVOT) is very rare. The case is presented of 13-year-old asymptomatic boy who was referred to the cardiology clinic for evaluation of murmur, and was found to have a large mobile mass (3 x 2 cm) in the RVOT that protruded into the pulmonary artery across the pulmonary valve during systole, and relocated in the right ventricle in diastole. The patient underwent successful surgical excision of the tumor, which had a short stalk attached to the pulmonary valve. Macroscopic examination revealed a typical myxoma without any evidence of malignancy. This case elaborates the importance of early recognition and surgical excision of these tumors in order to prevent thromboembolic complications.

Abstract
A 40-year-old woman presented with an extensive anterior myocardial infarction. After initial thrombolytic therapy, coronary angiography was performed a few days later revealing normal coronaries with severe left ventricular dysfunction secondary to anterior wall akinesia. Echocardiography showed severe left ventricular systolic dysfunction and a patent foramen ovale (PFO). The patient had a history of long-term oral contraceptive consumption. A paradoxical embolus into the left coronary artery via a large PFO was suspected and was successfully treated with PFO closure.

Abstract
BACKGROUND Although percutaneous coronary intervention (PCI) is an excellent therapy for coronary artery disease, there is a paucity of information on the efficacy of PCI in improving diastolic function, especially in Iran. Because of the high prevalence of left diastolic dysfunction in coronary artery disease patients and its probable progression to heart failure, an evaluation of the role of PCI in improving diastolic function is required. METHODS Thirty patients scheduled for elective PCI were enrolled in this study providing that their systolic ejection fraction was > 40%. Before PCI and 48 hours and 3 months after PCI, echocardiography was done to evaluate some diastolic values in these patients. RESULTS The mean age of all the patients was 54 ± 10 year, and 20 patients were male. All the patients had a low degree of left ventricular diastolic dysfunction. Isovolumic relaxation time (115 ± 10 before treatment versus 120 ± 1 and 119 ± 3 respectively 48 hours and 3 months after treatment), mitral E wave velocity in septal (0.70 ± 0.05 before treatment vs. 0.71 ± 0.15 and 0.72 ± 0.12 respectively 48 hours and 3 months after treatment), and the peak velocity of late filling due to atrial contraction (mitral A wave velocity) in septal (0.74 ± 0.02 before treatment vs. 0.73 ± 0.01 and 0.68 ± 0.16 respectively 48 hours and 3 months after treatment) showed improvement after PCI. It is notable that early diastolic mitral annulus velocity (E') wave velocity in the septal part of the mitral annulus improved significantly 48 hours and 3 months after PCI (p value < 0.05). The early-to-late diastolic tissue velocity ratio of the mitral annulus (E/A) ratio of the mitral inflow improved 48 hours after PCI; it was statistically significant (p value = 0.05). Also, mitral A wave velocity in septal and the E/A ratio of the mitral inflow improved significantly 3 months after PCI (p value < 0.05). CONCLUSION Improvement in some of values related to left ventricular diastolic function followed by PCI shows that this method can be used to improve cardiac diastolic function in patients with symptomatic coronary artery disease.

Abstract
Recent studies have shown that patients with heart failure over-express pro-inflammatory cytokines which enhance natural killer (NK) activity and negatively influence contractility and contribute to the remodeling of myocardium. The question is that how cardiovascular drugs influence on the cytokines of Peripheral Blood Mononuclear Cells (PBMCs) in Chronic Heart Failure (CHF). To study the effect of cardiovascular drugs on PBMCs-cytokines and NK activity of CHF patients. PBMCs of CHF patients/normal controls collected by Ficoll-paque density centrifugation. NK activity against K562 target cell was measured with MTT colorimetric assay. PBMCs were cultivated in RPMI/FCS, stimulated with phytohaemaglutinin (PHA). Tumor necrosis factor (TNF)-alpha interleukin (IL)-6, IL-2 and IL-1beta of culture supernatants after 24 h incubation with/without furosemide, captopril and digoxin were measured with sandwitch ELISA. Patients had higher NK activity than controls (56.9% +/- 1.6 vs 50.9% +/- 1.2, p < 0.05). NK activity of patients who already consumed Captopril/Furosemide didn't show difference with controls. Captopril (3, 1, 0.3 microg mL(-1)) and Furosemide (5, 2.5, 1.25 microg mL(-1)) caused a dose dependent inhibition in TNF-alpha compared with control (329 +/- 23, 427 +/- 15, 519 +/- 19 and 343 +/- 19, 430 +/- 14, respectively vs. 562 +/- 24 pg mL(-1) p < 0.05). Furosemide caused a dose dependent decrease in IL-6 (421 +/- 31, 534 +/- 33 vs. 662 +/- 41 pg mL(-1) p < 0.05). Captopril and Furosemide didn't show any significant effect on IL-1beta/IL-2. Digoxin had no significant effect on PBMCs-cytokines. These data suggest that the immunomodulatory effects of Captopril and Furosemide may contribute to their beneficial and no long-term adverse effects on PBMCs.

Abstract
OBJECTIVE To assess the efficacy and safety of Melissa officinalis extract using a fixed dose (60 drops/day) in patients with mild to moderate Alzheimer's disease. DESIGN A four month, parallel group, placebo controlled trial undertaken in three centres in Tehran, Iran. METHODS Patients with mild to moderate Alzheimer's disease aged between 65 and 80 years (n = 42; 18 women, 24 men) with a score of >or= 12 on the cognitive subscale of Alzheimer's disease assessment scale (ADAS-cog) and <or= 2 on the clinical dementia rating (CDR) were randomised to placebo or fixed dose of Melissa officinalis extract. The main efficacy measures were the change in the ADAS-cog and CDR-SB scores compared with baseline. Side effects were systematically recorded. RESULTS At four months, Melissa officinalis extract produced a significantly better outcome on cognitive function than placebo (ADAS-cog: df = 1, F = 6.93, p = 0.01; CDR: df = 1, F = 16.87, p < 0.0001). There were no significant differences in the two groups in terms of observed side effects except agitation, which was more common in the placebo group (p = 0.03). CONCLUSIONS Melissa officinalis extract is of value in the management of mild to moderate Alzheimer's disease and has a positive effect on agitation in such patients.

Abstract
BACKGROUND Alzheimer's disease is characterized by a slow, progressive decline in cognitive function and behaviour. Acetylcholine esterase inhibitors are the only agents approved by the Food and Drug Administration for the treatment of Alzheimer's disease. All other agents prescribed for the treatment of Alzheimer's disease are used on an off-label basis. Current research into new drugs is focused on agents that will prevent, slow down and/or halt the progress of the disease process. Salvia officinalis has been used in herbal medicine for many centuries. It has been suggested, on the basis of traditional medicine, its in vitro cholinergic binding properties and modulation of mood and cognitive performance in humans, that Salvia officinalis might potentially provide a novel natural treatment for Alzheimer's disease. The objective of this study was to assess the efficacy and safety of Salvia officinalis extract using a fixed dose (60 drops/day), in patients with mild to moderate Alzheimer's disease, over a 4-month period. METHODS This was a 4-month, parallel group, placebo-controlled trial undertaken in three centres in Tehran, Iran. Patients with mild to moderate Alzheimer's disease aged between 65 and 80 years (n = 42, 18 women) with a score of > or = 12 on the cognitive subscale of Alzheimer's Disease Assessment Scale (ADAS-cog) and < or = 2 on the Clinical Dementia Rating (CDR) were randomized to placebo or fixed dose of S. officinalis extract. Over the 16 weeks, the main efficacy measures were the change in the ADAS-cog and CDR-Sum of Boxes scores compared with baseline. In addition, side-effects were systematically recorded throughout the study using a checklist. RESULTS At 4 months, S. officinalis extract produced a significant better outcome on cognitive functions than placebo (ADAS-cog: F = 4.77, d.f. = 1, P = 0.03) (CDR-SB: F = 10.84, d.f. = 1, P < 0.003). There were no significant differences in the two groups in terms of observed side-effects except agitation that appears to be more frequent in the placebo group (P = 0.09). CONCLUSIONS The results of this study indicate the efficacy of S. officinalis extract in the management of mild to moderate Alzheimer's disease. Moreover, S. officinalis may well reduce agitation of patients but this needs to be confirmed.

Abstract
OBJECTIVE Passionflower (Passiflora incarnata) is a folk remedy for anxiety. A double-blind randomized trial compared the efficacy of Passiflora incarnata extract with oxazepam in the treatment of generalized anxiety disorder. METHODS The study was performed on 36 out-patients diagnosed with GAD using DSM IV criteria. Patients were allocated in a random fashion: 18 to the Passiflora extract 45 drops/day plus placebo tablet group, and 18 to oxazepam 30 mg/day plus placebo drops for a 4-week trial. RESULTS Passiflora extract and oxazepam were effective in the treatment of generalized anxiety disorder. No significant difference was observed between the two protocols at the end of trial. Oxazepam showed a rapid onset of action. On the other hand, significantly more problems relating to impairment of job performance were encountered with subjects on oxazepam. CONCLUSION The results suggest that Passiflora extract is an effective drug for the management of generalized anxiety disorder, and the low incidence of impairment of job performance with Passiflora extract compared to oxazepam is an advantage. A large-scale trial is justified.

Abstract
OBJECTIVE Clonidine-based therapies have been utilized as the main protocol for opiate detoxification for several years. However, detoxification with clonidine has its limitations, including lack of efficacy for mental symptoms. Accumulating evidence shows the efficacy of Passiflora incarnata extract in the management of anxiety. In our continuing study of traditional medicines, which have neurotropic effects, this plant had an anxiolytic effect, which may be used as an adjuvant agent in the detoxification of opiates by clonidine. We present the results of a double-blind randomized controlled trial of clonidine plus passiflora extract vs. clonidine plus placebo in the outpatient detoxification of 65 opiates addicts. METHODS A total of 65 opiates addicts were assigned randomly to treatment with passiflora extract plus clonidine tablet or clonidine tablet plus placebo drop during a 14-day double-blind clinical trial. All patients met the DSM IV criteria for opioid dependence. The fixed daily dose was 60 drops of passiflora extract and a maximum daily dose of 0.8 mg of clonidine administered in three divided doses. The severity of the opiate withdrawal syndrome was measured on days 0, 1, 2, 3, 4, 7 and 14 using the Short Opiate Withdrawal Scale (SOWS). CONCLUSION Both protocols were equally effective in treating the physical symptoms of withdrawal syndromes. However, the passiflora plus clonidine group showed a significant superiority over clonidine alone in the management of mental symptoms. These results suggested that passiflora extract may be an effective adjuvant agent in the management of opiate withdrawal. However, a larger study to confirm our results is warranted.
