Abstract
Background Cardiovascular disease is a leading cause of morbidity and mortality. Therefore, it is essential to prevent cardiovascular diseases by correcting modifiable risk factors such as lowering lipid levels, lowering blood pressure, improving eating habits, giving up smoking, etc. The present study assessed the efficacy of herbal preparation containing Allium sativum (A. sativum), Commiphora mukul (C. mukul), and Trigonella foenum-graecum (T. foenum-graecum) in patients with hyperlipidemia. Methodology Patients were given extracts of A. sativum 350 mg, T. foenum-graecum 350 mg, C. mukul 200 mg, Picrorhiza kurroa (P. kurroa) 200 mg, and Piper nigrum (P. nigrum) 5 mg. Unichem Laboratories, Mumbai, provided placebo tablets similar in shape and size to herbal tablets. Patients were assessed for compliance, and a complete lipid profile was done at DO, D15, D46, D76, and D106. In addition, total cholesterol and high-density lipoprotein-cholesterol (HDL-C) serum triglyceride were estimated by the respective methods throughout the study. Results The weight of the patients remained stable, the mean weight before being 65.42 ± 8.35 kg and after completion of the study being 65.42 ± 8.35 kg. There were no changes in the ECG during or after the drug therapy in any of the patients. Group A comprised nine patients, and group B had ten patients. Serum creatinine (mg %) was 0.94 and 0.95, fasting blood sugar mg (%) was 111.05 and 99.63, and postprandial blood sugar (mg %) was 150.89 and 147.94 on pre-treatment and post-treatment, respectively. The mean serum triglyceride levels in group A were 271.11, 261.11, 293.89, 167.22, and 128.89, and serum HDL- C levels were 46.11, 46.11, 54.44, 52.22, and 54.44. Serum triglyceride levels in group B were 268, 268.5, 202, 171, and 116, and serum HDL- C levels were 48.5, 48, 50, 50, and 53.5 on day 0, 15, 46, 76, and 106, respectively. A significant reduction in total cholesterol levels was observed on D46, D76, and D106, with a maximum reduction on D76 (25.36%). Similarly, a reduction in serum triglyceride was also observed on D46, D76, and D106, with a maximum reduction on D106 (52.02%). A significant difference was observed (P <0.05). There was also a significant reduction of low-density lipoprotein cholesterol (LDL-C) on D46, D76, and D106, with the maximum reduction on D76 (28.79%). There was a significant rise of HDL-C on D46 and D106, with a maximum rise on D106 (15.41%). A significant difference was observed (P <0.05). Conclusion The study drugs are safe and efficacious in reducing the total cholesterol, serum triglycerides, LDL-C levels, and increasing HDL-C levels.

Biomedicines 2022; 10:biomedicines10020456. [PMID: 35203665 PMCID: PMC8962413 DOI: 10.3390/biomedicines10020456] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 02/08/2022] [Accepted: 02/10/2022] [Indexed: 12/31/2022] Open
Abstract
Introduction: Polycystic ovary syndrome (PCOS) is an endocrinological disorder that affects 5–15% of women of their reproductive age and is a frequent cause of infertility. Major symptoms include hyperandrogenism, ovulatory dysfunction, and often obesity and/or insulin resistance. PCOS also represents a state of chronic low-grade inflammation that is closely interlinked with the metabolic features. “Classical” pro-inflammatory lipid mediators such as prostaglandins (PG), leukotrienes (LT), or thromboxanes (TX) are derived from arachidonic acid (AA) and are crucial for the initial response. Resolution processes are driven by four families of so-called specialized pro-resolving mediators (SPMs): resolvins, maresins, lipoxins, and protectins. The study aimed to establish lipid mediator profiles of PCOS patients compared to healthy women to identify differences in their resolutive and pro-inflammatory lipid parameters. Material and Methods: Fifteen female patients (18–45 years) were diagnosed with PCOS according to Rotterdam criteria, and five healthy women, as a comparator group, were recruited for the study. The main outcome measures were: pro-inflammatory lipid mediators (PG, LT, TX) and their precursor AA, SPMs (resolvins, maresins, protectins, lipoxins), their precursors EPA, DHA, DPA, and their active biosynthesis pathway intermediates (18-HEPE, 17-HDHA, 14-HDHA). Results: The level of pro-inflammatory parameters in serum was significantly higher in PCOS-affected women. The ratio (sum of pro-inflammatory molecules)/(sum of SPMs plus hydroxylated intermediates) reflecting the inflammatory state was significantly lower in the group of healthy women. Conclusion: There is a strong pro-inflammatory state in PCOS patients. Further research will clarify whether supplementation with SPMs or their precursors may improve this state.

Abstract
Atherosclerosis is a chronic disease characterized by lipid accumulation and chronic inflammation of the arterial wall, which is the pathological basis for coronary heart disease, cerebrovascular disease and thromboembolic disease. Currently, there is a lack of low-cost therapeutic agents that effectively slow the progression of atherosclerosis. Therefore, the development of new drugs is urgently needed. The research and development of marine-derived drugs have gained increasing interest from researchers across the world. Many marine organisms provide a rich material basis for the development of atherosclerotic drugs. This review focuses on the latest technological advances in the structures and mechanisms of action of marine-derived anti-atherosclerotic substances and the challenges of the application of these substances including marine polysaccharides, proteins and peptides, polyunsaturated fatty acids and small molecule compounds. Here, we describe the theoretical basis of marine biological resources in the treatment of atherosclerosis.

Abstract
Our aim was to investigate the relationship between plasma interleukin-6 (IL-6) levels with different measures of central obesity among Saudi women with and without polycystic ovarian syndrome (PCOS). One hundred and sixty-four Saudi females, between 22 and 38 years of age, with and without PCOS were enrolled in this case-control study. Physical examination and laboratory tests were completed for every subject. 2/3 of the study population were obese. Fasting serum insulin, plasma IL-6 levels and insulin resistance show significant increase among POCS than the controls (p<.05). Based on linear regression analysis, C-reactive protein (hs-CRP) was the only independent predictor of plasma IL-6 levels, accounting for 4% of the variability in plasma IL-6 (β = 0.217, p=.005, 95% CI: 0.049-0.275). Coexistence of metabolic and inflammatory factors in PCOS females is accompanied by central obesity which overpowers the effect of insulin resistance, contributing to higher plasma levels of IL-6 and CRP.Impact statementWhat is already known on this subject? Polycystic ovary syndrome (PCOS) is a cluster of many cardiovascular risk factors, but is also known as an inflammatory condition. Insulin resistance and abdominal obesity are classic components of PCOS. High circulatory levels of inflammatory markers in PCOS patients have been reported but it remains unclear whether their elevation is related to PCOS itself, or are a function of abdominal adiposity.What the results of this study add? The relationship between plasma interleukin-6 levels and different measures of central obesity was investigated among Saudi women with and without PCOS. Elevations of proinflammatory cytokines and inflammatory markers were reported in PCOS patients independently of insulin resistance. It remains to be established whether the proinflammatory state in PCOS is primarily due to inflamed adipose tissue.What the implications are of these findings for clinical practice and/or further research? The present study demonstrates that coexistence of metabolic and inflammatory factors in PCOS females are accompanied by central obesity which overpowers the effect of insulin resistance, contributing to higher plasma levels of IL-6 and CRP. Future studies including a larger population are needed to investigate the mechanisms by which IL-6 and hs-CRP promote cardiovascular risk in PCOS patients.

A multimethod approach examining the relative contributions of optimism and pessimism to cardiovascular disease risk markers. J Behav Med 2020; 43:839-849.

Abstract
Although dispositional optimism and pessimism are associated with cardiovascular disease (CVD), their relative independence and unique contributions to CVD risk are unclear. This study addressed these issues by using multiple indicators of optimism and pessimism and linking them to objective risk factors for CVD. A diverse sample of adults (N = 300) completed baseline assessments (including global reports of optimism and pessimism), a 2-day/1-night EMA protocol with ambulatory blood pressure (BP) at 45-min intervals, and had inflammatory markers and carotid intima media imaging collected. EMA reports of momentary positive and negative expectations were averaged to form intraindividual (person) means of optimism and pessimism, respectively. Optimism and pessimism were only modestly correlated between- and within-assessment methods. Higher pessimism, regardless of assessment method, predicted both lower odds of whether BP dipping occurred and a smaller degree of dipping, but was unrelated to other biomarkers. Optimism was not uniquely predictive of CVD risk factors. Pessimism thus appears to exhibit stronger relative contribution to risk indicators of CVD than optimism.

Abstract
Artemisia integrifolia L. (Compositae) is a medicinal and edible plant. To investigate its antihyperlipidemic effect, a crude lipophilic extract and the composing compounds were isolated and fractioned from the petroleum ether extract of aerial parts of A. integrifolia using column chromatography on silica gel. The anti-hyperlipidemia effect was studied in a rat model of acute hyperlipidemia, which was induced by triton WR-1339. A new compound, integrinol (4), together with nine known compounds, namely chamazulene (1), acetylenes (E)-2 (2), acetylenes (E)-3 (3), eugenol (5), palmitic acid (6), oleic acid (7), linoleic acid (8), linolenic acid (9) and 12,13-epoxylinolenic acid were isolated from the crude lipophilic extract of A. integrifolia. The LD50 value of the crude extract was more than 4 g/kg. In Triton WR-1339-induced acute hyperlipidemia model, the crude lipophilic extract (200 mg/kg) significantly reduced total cholesterol (TC) by 70% (p ≤ 0.01) and triglycerides (TGs) by 94% (p ≤ 0.001). The fractioned compounds, such as chamazulene (1), acetylene-2 (2), and linolenic acid (9), used at 4 mg/kg dose, also significantly decreased the concentrations of TC (32%, 33% and 64%, respectively) and TGs (48%, 33% and 93%, respectively). These compounds (i.e., chamazulene, acetylenes (E)-2, and linolenic acid) were considered to be responsible for the bioactive antihyperlipidemic effect. In conclusion, the crude lipid extract of Artemisia integrifolia L. could be used as a potential treatment to avert hyperlipidemia. Further studies to confirm these results in other models of hyperlipidemia (e.g., diet-induced obesity) are warranted.

Abstract
BACKGROUND Plant-based natural extracts cure several diseases in human. However, the extract of Psidium guajava leaf is not yet evaluated on changes of lipid profile in hepatic disease affected rats. OBJECTIVE The present study was aimed to evaluate the mitigation effect of the ethanolic extract of P. guajava leaf and its isolated quercetin fraction on hepatotoxic rats. MATERIALS AND METHODS Carbon tetrachloride (CCl4) was injected to rats for hepatic disease induction and silymarin drug was used as positive control to compare plant ethanolic extract. The lipid profiles were assessed in both plasma and liver tissue of diseased and control rats. RESULTS Levels of total cholesterol, triglycerides, free fatty acids, phospholipids, and low-density lipoprotein cholesterol were increased and the level of high-density lipoprotein cholesterol (HDL-C) was decreased in CCl4-induced hepatotoxic rats. The treatment of P. guajava (100, 200, and 300 mg/kg, bw) and isolated quercetin fraction (20 mg/kg, bw) doses decreased the elevated levels of all these parameters in diseased rats and restored the normal concentration of HDL-C. CONCLUSION The results of the present study concluded that the P. guajava leaf and its isolated quercetin fraction can significantly regulate lipid metabolism in CCl4-induced hepatotoxic rats and decrease the disease rate. SUMMARY Psidium guajava leaf extract reduces the hepatotoxicity and disease rate in ratsQuercetin fraction of leaf extract significantly regulates lipid profile in hepatic diseased rats. Abbreviations used: CCl4: Carbon tetrachloride; FFA: Free fatty acids; HDL-C: High-density lipoprotein cholesterol; LCAT: Lecithin cholesterol acyltransferase; LDL-C: Low-density lipoprotein cholesterol; PL: Phospholipids; TC: Total cholesterol; TG: Triglycerides; VLDL-C: Very low-density lipoprotein cholesterol.

Abstract
Polycystic ovarian syndrome (PCOS) is associated with multiple cardiovascular risk factors (CVRF) including endothelial dysfunction (ED) and presence of metabolic syndrome (MS). The probable reason suggested for elevated CVRF in PCOS is oxidative stress (OS), which is an integral factor in cardiometabolic complications (CMC) seen in PCOS women. The interrelated mechanisms by which CVRF instigate clinical manifestation plays a crucial role in identification of a strategy to treat different comorbidities in PCOS. The existing treatment for PCOS mostly focuses on management of individual disorders, however, therapeutic strategies or novel targets to address cardiovascular complications in PCOS deserve extensive analysis.

Abstract
Understanding the interactions between food and human biology is of utmost importance to facilitate the development of more efficient nutritional interventions that might improve our wellness status and future health outcomes by reducing risk factors for non-transmittable chronic diseases, such as cardiovascular diseases, cancer, obesity and metabolic syndrome. Dissection of the molecular mechanisms that mediate the physiological effects of diets and bioactive compounds is one of the main goals of current nutritional investigation and the food industry as might lead to the discovery of novel biomarkers. It is widely recognized that the availability of robust nutritional biomarkers represents a bottleneck that delays the innovation process of the food industry. In this regard, omics sciences have opened up new avenues of research and opportunities in nutrition. Advances in mass spectrometry, nuclear magnetic resonance, next generation sequencing and microarray technologies allow massive genome, gene expression, proteomic and metabolomic profiling, obtaining a global and in-depth analysis of physiological/pathological scenarios. For this reason, omics platforms are most suitable for the discovery and characterization of novel nutritional markers that will define the nutritional status of both individuals and populations in the near future, and to identify the nutritional bioactive compounds responsible for the health outcomes.

Relation Between Circulating Inflammatory Chemokines and Vascular Characteristics in Healthy, Young Children. J Am Heart Assoc 2015; 4:e002346. [PMID: 26675251 PMCID: PMC4845277 DOI: 10.1161/jaha.115.002346] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2015] [Accepted: 10/07/2015] [Indexed: 12/17/2022]
Abstract
BACKGROUND Atherosclerosis begins in childhood with the occurrence of inflammatory vascular wall alterations that are detectable with B-mode ultrasound. Chemokines appear to be involved in the development of these alterations given that they occur early in the atherosclerotic pathway as mediators of vascular inflammation. However, this has not extensively been investigated. Therefore, we studied in healthy young children whether chemokines monocyte chemotactic protein 1 (MCP-1), regulated on activation normal T-cell expressed and secreted (RANTES), and vascular and intercellular adhesion molecules (VCAM and ICAM) related to vascular characteristics of the carotid artery. METHODS AND RESULTS We obtained demography, anthropometry, and overnight fasting plasma of 139 eight-year-old children of the Wheezing Illnesses Study Leidsche Rijn birth cohort. Carotid intima-media thickness (CIMT), distensibility, and Young's Elastic Modulus (YEM) of the common carotid artery were measured sonographically. Chemokine plasma levels were assessed using a multiplex assay. We studied the relation between the chemokines and vascular characteristics using multivariable linear regression analyses with adjustments for sex, systolic blood pressure, homeostasis model assessment of insulin resistance, triglycerides, low-density lipoprotein- and high-density lipoprotein-cholesterol. Of the studied chemokines, RANTES related to common carotid distensibility and YEM. One standard deviation increase in RANTES level related to a 5.45-MPA(-1) (95% confidence interval [CI], -9.43, -1.39; P=0.01) decrease in distensibility and to a 5.55-kPa increase in YEM (95% CI, 0.40, 10.85; P=0.03). RANTES did not relate to CIMT. MCP-1, VCAM, and ICAM did not relate to any of the studied vascular characteristics. CONCLUSION RANTES appears to be involved in the development of preatherosclerotic inflammatory vascular alterations already in healthy, young children. This may provide further insight into the early-life origins of atherosclerosis.

Abstract
INTRODUCTION Numerous herbal medicines have been recommended for the treatment of different diseases. Achyranthes aspera, Linn. (Family: Amaranthaceae), popularly known as Charchitta or Pitpapra, is commonly used by traditional healers for the treatment of fever, malaria, dysentery, asthma, arterial hypertension, pneumonia, and diabetes. The root extract is well reputed for its insect molting hormonal activity. This investigation was conducted to evaluate the effects of saponins from Achyranthes aspera seeds on the serum lipid profile of albino rats fed a high cholesterol diet. MATERIAL AND METHODS Hypolipidemic, antioxidant and hepatoprotective activities of these saponins were tested as described previously. To determine the mechanism underlying the observed effects, serum antioxidant status was assessed according to ABTS (2,2'-azino-bis-3-ethylbenzo-thiazoline-6-sulfonic acid), superoxide dismutase and ferric ion reducing antioxidant power (FRAP) assays in saponin-treated hyperlipidemic animals. Liver enzyme levels were determined to reveal any possible hepatotoxicity. RESULTS Four-week oral administration of A. aspera seed saponins produced a significant (p < 0.05) decrease of total cholesterol, total triglycerides and LDL-C and a significant increase of HDL-C level in hyperlipidemic rats. Treatment with A. aspera seed saponins also showed a significant (p < 0.01) improvement of serum antioxidant status in tested animals. No significant hepatotoxicity was produced by such treatment as the serum liver enzyme activity remained unaltered. CONCLUSIONS Saponins from A. aspera seeds possess antihyperlipidemic and antioxidant properties which might lead to improvement of serum lipid profile and blood antioxidant status. Our findings support the folkloric use of this indigenous plant in the treatment of hyperlipidemia. However, its exact mechanism of action remains to be elucidated.

Abstract
Cardiac disease has emerged as the leading cause of death worldwide, and food rich in phenolic acids has drawn much attention as sources of active substances of hypolipidemic drug. Ananas comosus L. (pineapple) is one of the most popular tropical and subtropical fruits. Isolated from pineapple leaves, EAL(Extract of Ananas Comosus L. Leaves) is rich in phenolic acids, such as p-coumaric acid, caffeic acid, and other phenolics, highly relevant to the putative cardiovascular-protective effects, which suggests its potential to be a new plant medicine for treatment of cardiac disease, but little is known about absorption, distribution, metabolism, and excretion of EAL in animals or human beings. In this study, we employed cDNA microarray, Caco-2 cell lines, and rat intestinal model to explore the absorption behavior of p-coumaric acid and caffeic acid in EAL. The permeation of 2 substances was concentration and time dependent. Results also indicated that monocarboxylic acid transporter was involved in the transepithelial transport of p-coumaric acid and caffeic acid.

Abstract
OBJECTIVE The aim of this study was to evaluate serum concentrations of interleukin-6 (IL-6) in relation with hormonal and metabolic profile in patients with and without polycystic ovary syndrome (PCOS). METHODS A total of 40 women with PCOS and 40 age-matched controls were eligible for the study. Hirsutism scores, hormonal and metabolic profile as well as IL-6 levels were evaluated in each subject. RESULTS Women with PCOS exhibited higher body mass index (BMI) and serum concentrations of IL-6 levels than controls (p < 0.05); however, levels of IL-6 were not significantly increased when compared with BMI-matched controls (p > 0.05). IL-6 levels were significantly correlated positively with BMI and triglyceride levels; however, negatively correlated with high-density lipoprotein levels. CONCLUSION The data of this study suggested that serum IL-6 levels were found to be higher in women with PCOS as compared to controls; however, IL-6 levels might be dependent on nutritional status but not on PCOS per se. Raised serum IL-6 levels may be related to BMI and serum lipid levels and may be a predictor for cardiometabolic risks.

Abstract
The inhibitory effect of polyphenol extracts (Seapolynol™, SPN) of the marine brown algae Ecklonia cava and dieckol, a major component of SPN, on hyperlipidemia was investigated in ICR mice fed a high-fat diet (HFD) for five weeks. For analysis of the anti-hyperlipidemic effects of SPN and dieckol, these two agents were given orally on a daily basis to HFD-fed mice for four weeks, starting one week after the beginning of HFD feeding. Groups administered with SPN as well as dieckol showed lower body weight gains than the HFD only group. Administration of SPN and dieckol also resulted in a significant reduction of the level of total cholesterol (TCHO), triglyceride (TG), and low-density lipoprotein (LDL) cholesterol in the serum of HFD-fed mice. In Oil Red O staining using 3T3-L1 preadipocytes, it was shown that both SPN and dieckol markedly inhibited lipid accumulation of 3T3-L1 cells. Furthermore, SPN and dieckol (50 μg/mL) significantly inhibited 3-hydroxyl-methyl glutaryl coenzyme A (HMGCoA) reductase activity in vitro. Taken together, these results suggest that polyphenols of Ecklonia cava (SPN) and dieckol reduce body weight gain and fat accumulation in HFD-induced obese mice, and that their hypolipidemic effect is related to the inhibition of adipogenesis of adipocytes and HMGCoA reductase activity.

Abstract
BACKGROUND Tamarindus indica (T. indica) is a medicinal plant with many biological activities including anti-diabetic, hypolipidaemic and anti-bacterial activities. A recent study demonstrated the hypolipidaemic effect of T. indica fruit pulp in hamsters. However, the biochemical and molecular mechanisms responsible for these effects have not been fully elucidated. Hence, the aims of this study were to evaluate the antioxidant activities and potential hypocholesterolaemic properties of T. indica, using in vitro and in vivo approaches. METHODOLOGY/PRINCIPAL FINDINGS The in vitro study demonstrated that T. indica fruit pulp had significant amount of phenolic (244.9 ± 10.1 mg GAE/extract) and flavonoid (93.9 ± 2.6 mg RE/g extract) content and possessed antioxidant activities. In the in vivo study, hamsters fed with high-cholesterol diet for ten weeks showed elevated serum triglyceride, total cholesterol, HDL-C and LDL-C levels. Administration of T. indica fruit pulp to hypercholesterolaemic hamsters significantly lowered serum triglyceride, total cholesterol and LDL-C levels but had no effect on the HDL-C level. The lipid-lowering effect was accompanied with significant increase in the expression of Apo A1, Abcg5 and LDL receptor genes and significant decrease in the expression of HMG-CoA reductase and Mtp genes. Administration of T. indica fruit pulp to hypercholesterolaemic hamsters also protected against oxidative damage by increasing hepatic antioxidant enzymes, antioxidant activities and preventing hepatic lipid peroxidation. CONCLUSION/SIGNIFICANCE It is postulated that tamarind fruit pulp exerts its hypocholesterolaemic effect by increasing cholesterol efflux, enhancing LDL-C uptake and clearance, suppressing triglyceride accumulation and inhibiting cholesterol biosynthesis. T. indica fruit pulp has potential antioxidative effects and is potentially protective against diet-induced hypercholesterolaemia.

Abstract
Even after a successful renal transplantation, the renal transplant recipients (RTRs) keeps on suffering the consequences of the uremic sickness. Cardiovascular risk, work capacity, and quality of life do not improve according to expectations since biological and psychological problems are not completely solved by pharmacological treatment. Furthermore, post-transplant treatment, per se, induces additional problems (i.e., side effects of drugs). It becomes, indeed, very important to insert “non-pharmacological” therapies able to reverse this trend. Exercise may represent an important contribution in the solution of this problem. In fact, many studies have demonstrated, in the last two decades, that physical training is able both, to improve graft function, work capacity and quality of life, and to reduce cardiovascular risk. In conclusion, if the analysis of the available data suggests that an appropriate dose of physical training represent a useful, safe and non-pharmacologic contribution to RTR treatment, it becomes a kidney transplantologist responsibility to introduce exercise in the current therapy of RTRs.

Abstract
OBJECTIVE Women with gestational diabetes mellitus (GDM) treated with insulin are more likely to develop type 2 diabetes after pregnancy compared to mild GDM cases treated with medical nutrition treatment (MNT) alone. We aimed to compare levels of subclinical atherosclerosis markers in women with previous GDM treated with insulin and MNT alone. METHODS Eighty-one women with previous GDM (45 treated with insulin, 36 treated with MNT) and 35 age-matched lean controls were included. Fasting glucose, insulin and lipids, circulating fibrinogen, CRP, PAI-1 and IL-6 levels were assayed. Carotid intima media thickness (IMT) was measured. RESULTS Women with previous GDM treated with insulin in pregnancy had significantly higher fasting glucose, plasma PAI-1 levels and carotid IMT compared to women treated with MNT alone. In multiple regression analysis, insulin need in pregnancy was associated with increased carotid IMT and plasma PAI-1 levels (corrected for age, BMI, postpartum duration, fasting glucose and lipids; model r(2)=0.132; beta=0.297, p=0.014 for carotid IMT; model r(2)=0.198; beta=0.345, p=0.003 for PAI-1). CONCLUSION Women with previous GDM treated with insulin in pregnancy had a worse cardiovascular risk profile compared to mild GDM patients. An intensive preventive approach for cardiovascular disorders is particularly essential for this subgroup of women.

Abstract
Due to its physiologic role in modulating adhesive interactions between blood cells and the endothelium during inflammatory processes or at injury sites, the adhesion molecule P-selectin is of great interest. The level of soluble P-selectin in plasma or serum can be detected and used as a clinical predictor for adverse cardiovascular events, leading to the presumption that it is secreted, shed or cleaved from the cell membrane during the process of diseases. Increased levels of soluble P-selectin in the plasma have been shown to be associated with a range of cardiovascular disorders, including coronary artery disease, hypertension and atrial fibrillation. Therefore, it is of huge significance to develop simple, rapid and sensitive methods for the detection of such pathological predictors, not only for facilitating the surveillance of cardiovascular mortality/sudden cardiac death, but also for effectively monitoring the drug potency on platelets based on measurement of P-selectin performed on fixed blood samples following platelet stimulation in whole blood in a remote setting. We herein developed a simple, yet novel and sensitive electrochemical sandwich immunosensor for the detection of P-selectin; it operates through covalent linkage of anti-P-selectin antibody on CNT@GNB nanocomposites-modified disposable screen-printed electrode as the detection platform, with the potassium ferrocyanide-encapsulated, anti-P-selectin-tagged liposomal biolabels as the electrochemical signal probes. The immunorecognition of the sample P-selectin by the liposomal biolabels occurred on the surface of the electrodes; the release of potassium ferrocyanide from the bound liposomal biolabels extensively contributed to the increase in electrochemical signal, which was acquired in HCl solution at +0.32V in square wave voltammetry mode. The resulting sigmoidally shaped dose-response curves possessed a linear dynamic working range from 1×10(-13) to 1×10(-5)g/mL. This liposome-based electrochemical immunoassay provides an amplification approach for detecting P-selectin at trace levels, leading to a detection limit as low as 4.3fg (equivalent to 5μL of 0.85pg/mL solution). A commercially available ELISA kit was used as a reference method to validate the newly-developed assay through the analysis of mouse serum samples. A strong correlation was observed between the two data sets as the R-squared value of 0.997 from the linear regression line. This electrochemical immunosensor will be useful for the detection of P-selectin in biological fluids and tissue extracts.

Abstract
In the search for new potential antihyperlipidemic agents, the present study focuses on the synthesis of novel N-(benzoylphenyl)-5-substituted-1H-indole-2-carboxamides (compounds 8-12, 15, 16, 18) and investigating their antihyperlipidemic activity using Triton WR-1339-induced hyperlipidemic rats as an experimental model. Hyperlipidemia was developed by intraperitoneal injection of Triton WR-1339 (250 mg/kg body weight). The tested animals were divided into normal control (NCG), hyperlipidemic (HG), compound 8, 9, 15, 16, 18- and bezafibrate treated groups. At a dose of 15 mg/kg body weight, compounds 9, 16, 18 and bezafibrate (100 mg/kg) significantly (p < 0.0001) reduced elevated plasma triglycerides levels after 12 h compared to the hyperlipidemic control group. However, only the group treated with compounds 9, 16 and 18 showed an obviously significant (p < 0.001) reduction in plasma total cholesterol levels after 12 h compared to the hyperlipidemic control group. Moreover, high density lipoprotein-cholesterol levels were significantly (p < 0.0001) increased in all treated groups after 12 h compared to the hyperlipidemic control group, except for compounds 8 and 15 which revealed inactive. It is therefore reasonable to assume that compounds 9, 16 and 18 may have potential in the treatment of hyperlipidemia.

Abstract
BACKGROUND AND AIMS Several studies have suggested that polyunsaturated fatty acids, vitamins and minerals have beneficial effects on lipid profile and systemic inflammation in adults. METHODS AND RESULTS We examined the effects of a daily intake of milk enriched with longchain polyunsaturated fatty acids, oleic acid, carbohydrates, vitamins, minerals and low in saturated fatty acids (SFAs) for 5 months, on several cardiovascular (CVD) risk biomarkers in healthy children aged 8-14 years. In a randomized double-blind placebo-controlled trial, a total of 107 children of both genders were assigned to two study groups: 1) a supplemented group (SG, n=53) who consumed 0.6 L/day of an enriched dairy product, and 2) a control group (CG, n=54) who consumed 0.6 L/day of standard whole milk. Both groups consumed the dairy drinks for 5 months, in addition to their usual diet. Serum levels of adhesion molecules as indices of vascular endothelial cell activation were assessed in both groups at 0 and 5 months as well as white blood cell counts, lipid profile, serum proteins, total serum calcium, 25-OH vitamin D, glucose, insulin and adiponectin. In the enriched dairy drink supplemented group, adhesion molecules E-selectin and ICAM-1 as well as lymphocyte levels decreased while plasma docosahexaenoic acid (DHA) and serum calcium concentrations increased. In the control group, serum total protein, transferrin, total cholesterol, HDL-cholesterol and adiponectin concentrations decreased. CONCLUSION The consumption of a milk enriched with fish oil, oleic acid, minerals and vitamins reduced indices of endothelial cell activation in the studied group of healthy children.

Abstract
Several Thai spices/dietary ingredients were previously shown to have hypocholesterolaemic effects. These studies were mostly conducted in animal models in which the mechanisms of action were not yet well-established. Therefore, this study aimed to investigate the potential mechanism of hypocholesterolaemic action of 12 selected plants, namely Hibiscus sabdariffa L., Moringa oleifera Lam., Cucurbita moschata Duchesne, Ananas comosus (L.) Merr., Zingiber officinale, Morus alba L., Camellia sinensis (L.) Kuntze, Piper nigrum L., Alpinia galanga (L.) Willd., Curcuma zedoaria Rose, Bacopa monnieri (L.) Wettst. and Piper retrofractum Vahl., widely used as spices and ingredients in various types of Thai food. The extract of P. nigrum at 100 µg mL(-1) was found to be the most effective cholesterol uptake inhibitor whereas those of A. galanga and C. sinensis effectively inhibited pancreatic lipase activity with IC50 values of 8.99±3.41 and 12.36±1.23 µg mL(-1), respectively. The potency of extracts from H. sabdariffa, M. oleifera and C. moschata at 100 µg mL(-1) were found to be similar to 0.4 µg mL(-1) pravastatin in inhibiting HMG-CoA reductase and possibly reduced cholesterol biosynthesis. This study also demonstrated that several of the tested plants possessed multiple sites of action that were possibly responsible for their cholesterol-lowering effect in the in vivo model.

Abstract
The lipid-lowering activity of a series of novel N-(benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide derivatives has been studied in Triton WR-1339-induced hyperlipidemia in rats. The test animals were divided into four groups: control, hyperlipidemic, compound + 4% DMSO [C1: N-(2-benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide (1), C2: N-(3-benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide (2), C3: N-(4-benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide (3)]-treated and bezafibrate (BF)-treated. At a dose of 15 mg/Kg body weight, compounds 2, 3 and BF significantly reduced elevated plasma triglycerodes levels after 12 h. Moreover, high density lipoprotein-cholesterol levels were significantly increased in all treated groups after 12 h compared to the hyperlipidemic control group, except for C1 which was inactive. In sum, it may be stated that the results of the present study demonstrated new properties of some N-(benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide derivatives as potent lipid lowering agents and these beneficial activities may contribute to their cardioprotective and antiatherosclerotic role.

Abstract
Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age group and is associated with a higher cardiovascular risk. Obesity, mainly visceral adiposity, is prevalent in patients with PCOS. Obesity is associated with low-grade inflammation and raised inflammatory cytokines, both of which are also described in patients with PCOS. In this paper, the potential relationships between fat distribution, adipocyte dysfunction and, altered inflammatory markers in patients with PCOS have been discussed.

Abstract
OBJECTIVE To investigate the possible role of apolipoprotein M (ApoM) in the development of coronary artery disease (CAD). DESIGN AND METHODS Case-controlled study, which consisted of 118 CAD patients and 255 unrelated subjects used as control group. Plasma concentration of ApoM was determined by dot blot, severity of CAD was expressed with Gensini score or the numbers of lesioned coronary arteries, and serum lipid levels were also measured. RESULTS AND DISCUSSION Our study shows the mean level of plasma ApoM is 1.3757+/-0.1493 ODu mm(-2) in CAD patients, while it is 1.3502+/-0.1288 ODu mm(-2) in control group, and there are significant differences in plasma level of ApoM between two groups (t=0.032, P<0.05). Concentration of plasma ApoM is positively associated with plasma total cholesterol (r=0.38, P=0.025), high density lipoprotein cholesterol (r=0.29, P=0.03), low density lipoprotein cholesterol (r=0.16, P=0.03) and apolipoproein A-I (r=0.24, P=0.03). Multiple logistic and linear regression analysis showed that plasma concentration of ApoM did not correlate either with the number of lesioned coronaries or the Gensini score after adjusted for conventional cardiovascular risk factors (P>0.05, respectively). CONCLUSION The findings suggest that ApoM could not be an independent risk factor but a biomarker of CAD.

Abstract
Systemic lupus erythematosus (SLE) is associated with premature atherosclerosis. We previously showed that SLE patients have a higher risk of insulin resistance (IR) and abnormal insulin secretion. The present study was to further investigate the relationship between fasting insulin levels and both classic and novel cardiovascular risk factors in patients with SLE. Body mass index (BMI), fasting glucose and insulin, lipid profile, oxidation markers, fibrinolytic factors, vascular function factors, and disease-specific variables were determined in a total of 87 female SLE patients. The homeostasis model assessment (HOMA) was used to evaluate the IR and secretion. SLE patients had significantly higher fasting insulin, HOMA IR, HOMA beta-cell, titers of autoantibodies against oxidized low density lipoprotein, systolic blood pressure, homocysteine, and brachial-ankle pulse wave velocity (baPWV) than age-matched healthy controls. There were no statistical differences in disease duration, anti-dsDNA, C3, C4, disease activity, and medication dosage between SLE patients stratified by fasting insulin levels. However, mean values for BMI, insulin, HOMA IR, HOMA beta-cell, triglyceride (TG), homocysteine, and baPWV were significantly higher in the SLE patients with hyperinsulinemia when compared with those SLE controls. In addition, fasting insulin levels were positively correlated with TG, homocysteine, blood pressure, plasminogen activator inhibitor 1, and baPWV in SLE patients. The elevation of fasting insulin levels in SLE patients is not only associated with IR, but is related to classic and novel cardiovascular risk factors. This study concludes that there is an insulin-related cardiovascular disease risk in SLE.

Selective serotonin re-uptake inhibitors decrease the cytokine-induced endothelial adhesion molecule expression, the endothelial adhesiveness to monocytes and the circulating levels of vascular adhesion molecules. Int J Cardiol 2008; 139:150-8. [PMID: 19004511 DOI: 10.1016/j.ijcard.2008.10.010] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2008] [Revised: 09/20/2008] [Accepted: 10/12/2008] [Indexed: 01/03/2023]
Abstract
BACKGROUND Selective serotonin reuptake inhibitors (SSRIs) exert cardioprotective effects. We examined whether SSRIs a) modulate endothelial cell expression of vascular cell adhesion molecule (VCAM-1), intracellular adhesion molecule (ICAM-1) and adhesiveness to U937 monocytes, b) reduce the circulating levels of these adhesion molecules in vivo. METHODS We assessed the effect of SSRIs, (citalopram, fluvoxamine and fluoxetine), on TNF-alpha-induced expression of VCAM-1 and ICAM-1 in human aorta endothelial cells and adhesiveness to U937 monocytes. Cells were incubated with TNF-alpha in the absence and in the presence of SSRIs concentrations from 10(-7) M to10(-4) M and the VCAM-1 and ICAM-1 expression was quantified by cell-ELISA. The TNF-alpha-stimulated adhesiveness to U937 monocytes was also assessed. Twenty five patients with chronic heart failure and depression were randomized to receive sertaline 50 mg, p.o., o.d. (n=13) or placebo. At baseline and 3-months after treatment, we measured VCAM-1 and ICAM-1 plasma levels. RESULTS SSRIs decreased the TNF-alpha-induced endothelial expression of VCAM-1 at concentration range 10(-7) M to 10(-4) M (p<0.05). ICAM-1 expression was decreased in the presence of fluvoxamine and fluoxetine at concentrations from 10(-7) M to 10(-4) M (p<0.05) and in the presence of citalopram at concentrations from 10(-7) M to 10(-5) M (p<0.05). All SSRIs inhibited the TNF-alpha-stimulated adhesiveness to U937 cells at 10(-5) M and 10(-4) M (p<0.05). Compared to baseline, there was a greater reduction in ICAM-1 and VCAM-1 levels post-sertaline than post placebo in heart failure patients (p<0.05). CONCLUSION SSRIs may exhibit an anti-inflammatory activity on endothelial cells and reduce circulating VCAM-1 and ICAM-1 in vivo, a mechanism which may partly mediate their cardioprotective effects.

Abstract
BACKGROUND We have evaluated the impact of the reproductive status of morbidly obese women, and of the time elapsed since surgery, on the response of the proinflammatory serum cardiovascular risk marker interleukin-18 (IL-18) to the sustained and marked weight loss achieved after bariatric surgery. METHODS Serum IL-18 levels were measured in 33 morbidly obese women before bariatric surgery and after losing at least 15% of the initial weight, irrespective of the time needed to achieve this goal (5 to 33 months). RESULTS Patients lost 30.7 +/- 7.8% of the initial weight, with a concomitant reduction of serum IL-18 concentrations (P<0.001). A stepwise multiple regression analysis showed that the percentual decrease in serum IL-18 levels was determined by the interaction between the time elapsed since surgery and the percentual reduction of waist circumference (R2 = 0.333, F = 15.500, beta = 0.577, P<0.001), but not by the individual effects of the time elapsed since surgery, percentual body weight loss, percentual reduction of waist circumference, menopausal status or type of surgical procedure, or by the interaction between the time elapsed since surgery with the percentual body weight loss or with menopausal status. CONCLUSION Serum IL-18 levels decrease after bariatric surgery in a time-dependent manner, in relation to the reduction in waist circumference. The fact that the amelioration of the obesity-associated inflammatory process requires time and not only weight loss, might contribute to explain early non-surgical cardiovascular complications of bariatric surgery.

Abstract
AIM OF THE STUDY Nasturtium officinale R. Br. (Brassicaceae) is used as a home remedy in Iran as a cardioprotective agent without any scientific background. In this investigation an attempt was made to study the effect of Nasturtium officinale hydroalcoholic extract (NOE) on serum lipid profile which is closely associated with many cardiovascular diseases. MATERIALS AND METHODS Accordingly, serum total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) were among the parameters investigated. We also evaluated the activities of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels as a measure of hepatic cell damages. RESULTS Intragastric administration of NOE (500 mg/kg body weight per day) to groups of hypercholesterolaemic rats for 10 days lowered their serum TC, TG and LDL-C by 34.2, 30.1, and 52.9%, respectively, while raised the serum HDL-C level by 27.0% after 10 days of treatments. Treatment with NOE reduced serum ALT and AST levels compared to high-fat diet groups. CONCLUSIONS Based on these data, it is concluded that the NOE has definite cardioprotective potential and these results constitute a valid scientific basis for consuming Nasturtium officinale for medicinal application.

Abstract
OBJECTIVE We evaluated the effects of soy isoflavone supplementation on hemostasis in healthy postmenopausal women. METHODS In this double-blinded, placebo-controlled study, 47 postmenopausal women 47-66 y of age received 40 mg of soy isoflavone (n = 25) or 40 mg of casein placebo (n = 22) once a day for 6 mo. Levels of factors VII and X, fibrinogen, thrombin-antithrombin complex, prothrombin fragments 1 plus 2, antithrombin, protein C, total and free protein S, plasminogen, plasminogen activator inhibitor-1, and D-dimers were measured at baseline and 6 mo. Urinary isoflavone concentrations (genistein and daidzein) were measured as a marker of compliance and absorption using high-performance liquid chromatography. Baseline characteristics were compared by unpaired Student's t test. Within-group changes and comparison between the isoflavone and casein placebo groups were determined by a mixed effects model. RESULTS The levels of hemostatic variables did not change significantly throughout the study in the isoflavone group; however, the isoflavone group showed a statistically significant reduction in plasma concentration of prothrombin fragments 1 plus 2; both groups showed a statistically significant reduction in antithrombin, protein C, and free protein S levels. A significant increase in D-dimers was observed only in the isoflavone group. Plasminogen activator inhibitor-1 levels increased significantly in the placebo group. However, these changes were not statistically different between groups. CONCLUSION The results of the present study do not support a biologically significant estrogenic effect of soy isoflavone on coagulation and fibrinolysis in postmenopausal women. However, further research will be necessary to definitively assess the safety and efficacy of isoflavone.

Abstract
In this study, we investigated hypolipidemic mechanisms of the ethanolic extract of Ananas comosus L. leaves (AC) in mice and then determined its activities in related enzymes. The results showed that AC (0.40 g/kg) significantly inhibited the increase in serum triglycerides by 40% in fructose-fed mice. In mice induced by alloxan and high-fat diets, serum total cholesterol remained at a high level (180 - 220 mg/dl) within 7 days of removing high-fat diets but reached normal level (120 - 140 mg/dl) after AC (0.40 g/kg per day) treatment. Also, AC (0.40 and 0.80 g/kg) significantly inhibited serum lipids from the increase in Triton WR-1339-induced hyperlipidemic mice. AC (0.01 - 100 microg/ml) selectively activated lipoprotein lipase (LPL) activity by 200% - 400% and significantly inhibited 3-hydroxyl-methyl glutaryl coenzyme A (HMGCoA) reductase activity by 20% - 49% in vitro. Furthermore, 2 months of fenofibrate (0.20 g/kg) administration particularly increased mice liver weights (0.0760 +/- 0.0110 g/g) while AC (0.40 g/kg) had no effect (0.0403 +/- 0.0047). Taken together, these results suggest that AC will be a new potential natural product for the treatment of hyperlipidemia that exerts its actions through mechanisms of inhibiting HMGCoA reductase and activating LPL activities. Its action mechanisms differentiate from those with fibrates but may be partly similar to those with statins. It is hopeful that AC may serve as the adjuvant for fibrates.

Abstract
BACKGROUND The relationship between plasma biologic markers and coronary artery remodeling is unknown. HYPOTHESIS Plasma biologic markers are associated with coronary artery remodeling. METHODS Preintervention intravascular ultrasound images were obtained in 44 patients with chronic stable angina. Plasma samples were collected 24 h before coronary intervention. The biologic markers included total cholesterol, low-density lipoprotein (LDL) cholesterol, triglyceride, high-density lipoprotein (HDL) cholesterol, lipoprotein(a) [LP(a)], C-reactive protein (CRP), and homocysteine. The remodeling index (RI) was defined as a ratio of the (lesion/proximal reference) external elastic membrane cross-sectional area. Positive remodeling was defined as an RI > 1.05, negative remodeling as an RI <0.95, and intermediate remodeling as an RI between 0.95 and 1.05. RESULTS Total cholesterol level (r = 0.092, p = 0.557), LDL cholesterol level (r = 0.123, p = 0.426), triglyceride level (r = 0.020, p = 0.901), HDL cholesterol level (r = 0.042, p = 0.789), LP(a) level (r = 0.062, p = 0.729), and CRP level (r = 0.266, p = 0.089) did not significantly correlate with the RI. However, the plasma homocysteine level positively correlated with the RI (r = 0.398, p = 0.008). The plasma homocysteine level was significantly lower in the lesions with negative remodeling and higher in the lesions with positive remodeling (10.8 +/- 0.7 micromol/l in negative remodeling, 13.1 +/- 0.6 micromol/l in intermediate remodeling, and 18.1 +/- 2.8 micromol/l in positive remodeling, p = 0.021). CONCLUSIONS Elevated homocysteine levels might be associated with coronary artery remodeling in patients with stable angina.

Abstract
The polycystic ovary syndrome (PCOS) is a common disorder in premenopausal women, characterized by the presence, among other traits, of hyperandrogenism, insulin resistance, and hyperinsulinism. The familial aggregation of PCOS lead the interest to the molecular genetic basis of this syndrome, especially to the genes encoding proteins involved in androgen synthesis and the regulation of insulin synthesis and action. Considering the relationship between insulin resistance and chronic inflammation, and the clustering of inflammatory markers in PCOS patients, recent studies focused on the involvement of proinflammatory genotypes on the pathogenesis of PCOS. Mounting evidence suggest at present a complex model of inheritance for PCOS, in which predisposing and protecting genomic variants interact with environmental factors such as obesity and a sedentary lifestyle, finally leading to the classic phenotype of this syndrome. Moreover, the association of hyperandrogenism, insulin resistance and chronic inflammation raised the possibility of an increase risk of cardiovascular disease in women suffering from PCOS. In the present review we will summarize the most important findings published to date regarding the molecular genetic mechanisms underlying the association of PCOS with insulin resistance and chronic inflammation, and the possible interaction of these mechanisms with environmental factors.

Abstract
Recent studies show that clinically stable renal transplant recipients have an increased prevalence of hyperhomocysteinemia (hyperHcy), but the mechanism of this disorder has not yet been elucidated. The aim of the present study was to evaluate the factors associated with hyperHcy after a successful renal transplantation. In 106 stable renal transplant recipients, total serum Hcy level (tHcy), folate, total protein, serum creatinine concentration, creatinine clearance, lipid status, body weight (BW), body mass index (BMI), and body fat (BF) were determined. The mean doses of cyclosporine, prednisolone, and azathioprine (mg/kg/day) were recorded. The mean serum tHcy level was significantly higher in renal transplant patients than in healthy controls (22.02 +/- 8.02 versus 13.0 +/- 3.3 micromol/ L; p < 0.001), and the incidence of patients with hyperHcy was 82%. Comparison of the group of 20 patients with tHcy level <15 micromol/L and the group of 86 patients with tHcy level >15 micromol/L revealed that the latter was significantly older, heavier, had been longer on dialysis before renal transplantation, and had older donors and poorer renal graft function. Significant correlation was found between tHcy level and recipient age, dialysis duration, BW, creatinine clearance, serum creatinine, and folate concentration. However, multivariate analysis indicated that creatinine clearance (p = 0.025) and BW (p = 0.03) were the only determinants of elevated total Hcy level in renal transplant recipients. HyperHcy persists after successful kidney transplantation in the majority of renal transplant recipients, and its appearance is primarily associated with creatinine clearance and body weight.

Abstract
Atherosclerosis is characterized by the development of an intimal thickening that contains monocytes, T lymphocytes, and smooth muscle cells within an accumulation of lipid and extracellular matrix proteins. Vitronectin is a plasma glycoprotein implicated as a regulator of diverse physiological process, including blood coagulation, fibrinolysis, pericellular proteolysis, complement dependent immune responses, and cell attachment and spreading. Because of its ability to bind platelet glycoproteins and mediate platelet adhesion and aggregation at sites of vascular injury, vitronectin has become an important mediator in the pathogenesis of coronary atherosclerosis.

Abstract
OBJECTIVE The aim of this study was to determine the levels of plasma fibrinogen and C-reactive protein (CRP) in preeclampsia and their association with the severity of the disease. STUDY DESIGN CRP and plasma levels of fibrinogen were investigated in 26 cases of normal pregnant women, 26 cases with mild preeclampsia and 26 cases with severe preeclampsia in the third trimester of pregnancy. Mean arterial pressure (MAP) was used as an indicator of the severity of the disease. Analysis of variance with the Kruskal-Wallis test was used when three groups were compared. For correlations, Spearman's rank correlation tests were used. A receiver operating characteristic curve was constructed to evaluate the sensitivity and specificity of CRP. RESULTS Plasma CRP and fibrinogen levels in mild and severe preeclampsia patients were markedly higher than that of normal third trimester pregnant women. There were significant correlations between MAP and CRP (r = 0.515, p = 0.0001) and MAP and fibrinogen parameters (r = 0.383, p = 0.005) in pregnancies complicated with preeclampsia. CONCLUSION We found higher levels of fibrinogen and CRP and presence of good correlation between CRP and MAP in preeclampsia.

Abstract
In this study, the levels of fibronectin, vitronectin, leptin, tissue plasminogen activator (t-PA), and lipid parameters were investigated in patients with coronary artery disease (CAD) and control group. The average plasma fibronectin levels in CAD patients group were significantly higher compared with the control group (p=0.006). Moreover, in patients with triple-vessel disease, plasma fibronectin levels were found to be significantly higher than those in the control group (p<0.05). Plasma vitronectin levels in patients with CAD were found to be significantly higher than those in the control group (p=0.000). In addition, in patients with double vessel disease plasma vitronectin levels were significantly higher than no vessel disease and control group, triple vessel disease was significantly higher as compared with no vessel disease, single vessel disease, and control group (p<0.05). We could not find any significant differences in t-PA values between CAD patients and control group. On the other hand, the average leptin levels in the group of patients were higher than those in the control group but there were no statistically significant differences found between them (p>0.05) because of high SD values. There was strong (+) correlation between fibronectin, vitronectin, and severity of disease [vitronectin/severity of disease, r = 0.5074 (p = 0.000), fibronectin/severity of disease, r = 0.2971 (p = 0.007)]. In conclusion, we can say that fibronectin and vitronectin have become greatly important in pathogenesis of coronary artery disease. High leptin levels may be contribute to platelet aggregation in patients with coronary artery disease. But, elevated serum levels of leptin cannot be useful diagnostic and monitoring markers in patients with coronary artery disease.

Abstract
PURPOSE To study the age and gender effects on the distribution of lipoprotein (a) [Lp(a)] and its relationship with other cardiovascular disease (CVD) and diabetes risk factors in the participants of the Cherokee Diabetes Study (CDS) (1995-2000). METHODS The CDS is a population based cross-sectional study of diabetes and its risk factors in Cherokee Indians aged 5 to 40 years of Oklahoma. Lp(a) levels were measured in 2205 participants. RESULTS The median Lp(a) (mg/dL) levels in the females were not significantly different among four age groups (5-9, 10-19, 20-29, and 30-40 years). However, the 20- to 29-year-old males had significantly lower Lp(a) levels than the males 10 to 19 and 30 to 40 years old. Females had significantly higher Lp(a) levels than males in the 20- to 29-year-old age group only. In the 5- to 19-year-old children/adolescents, Lp(a) levels were significantly negatively correlated with the degree of Indian heritage (DIH) and positively correlated with total cholesterol (TC), low-density lipoproteins (LDL), and apolipoprotein B (apoB) in girls, but not in boys. In the young adults aged 20 to 29 years, Lp(a) levels were significantly correlated with DIH, body mass index (BMI), waist-hip ratio (WHR), percentage of body fat (PBF), systolic blood pressure (SBP), triglycerides (TG), 2-hour plasma glucose (2hPG), and insulin in males, and DIH, PBF, TC, LDL, TG, and insulin in females. In adults aged 30 to 40 years, Lp(a) levels were significantly correlated with DIH, TG, and LDL in females, and DIH and insulin in males. CONCLUSION In the girls, Lp(a) levels appear to be associated with several CVD and diabetes risk factors at an early age (5-19 years), while in the boys, the association occurs at older ages (> 19 years). There are significant age and gender differences regarding the distribution of Lp(a) and its correlates in the 5 to 9, 10 to 19, and 20 to 29-year-old age groups, but the differences tend to be weaker in the 30- to 40-year-old age group. For the same age and gender groups, Lp(a) concentrations in Cherokee Indians were much lower than those reported in blacks and slightly lower than those in whites. In Cherokee Indians, the Lp(a) levels were consistently and positively correlated with LDL, and negatively correlated with DIH, TG, and insulin.

Abstract
The genetic mechanisms underlying functional hyperandrogenism and the polycystic ovary syndrome (PCOS) remain largely unknown. Given the large number of genetic variants found in association with these disorders, the emerging picture is that of a complex multigenic trait in which environmental influences play an important role in the expression of the hyperandrogenic phenotype. Among others, genomic variants in genes related to the regulation of androgen biosynthesis and function, insulin resistance, and the metabolic syndrome, and proinflammatory genotypes may be involved in the genetic predisposition to functional hyperandrogenism and PCOS. The elucidation of the molecular genetic basis of these disorders has been burdened by the heterogeneity in the diagnostic criteria used to define PCOS, the limited sample size of the studies conducted to date, and the lack of precision in the identification of ethnic and environmental factors that trigger the development of hyperandrogenic disorders. Progress in this area requires adequately sized multicenter collaborative studies after standardization of the diagnostic criteria used to classify hyperandrogenic patients, in whom modifying environmental factors such as ethnicity, diet, and lifestyle are identified with precision. In addition to classic molecular genetic techniques such as linkage analysis in the form of a whole-genome scan and large case-control studies, promising genomic and proteomic approaches will be paramount to our understanding of the pathogenesis of functional hyperandrogenism and PCOS, allowing a more precise prevention, diagnosis, and treatment of these prevalent disorders.
