Abstract

BACKGROUND: Not only hypertension, prehypertension has been reported to be linked with increased cardiovascular morbidity and mortality risks as well. Prehypertension has three-fold hypertension and two-fold cardiovascular risks. Pathomechanism that links hypertension with cardiovascular is related with endothelial dysfunction and insulin resistance. Endothelial dysfunction occurs when nitric oxide (NO) biological function was impaired, whereas shown by asymmetric dimethylarginine (ADMA). Subjects with prehypertension had higher insulin resistance events than normotension, whereas shown by homeostatic model assessment-estimated insulin resistance (HOMA-IR). This research was conducted to investigate the correlation of HOMA-IR with ADMA in prehyper- and normo-tension.METHODS: A cross-sectional comparative research was designed. Subjects were recruited and divided into prehyper- and normo-tensive groups. ADMA was measured using ELISA method, while HOMA-IR was calculated by the ratio of fasting insulin and glucose. Spearman 1-tail and Mann Whitney statistical analyses were performed.RESULTS: Comparing to normotensive group, elevated levels of HOMA-IR and ADMA in prehypertensive group were shown, but not significant. In prehypertensive group, we found significant correlation between HOMA-IR and ADMA.CONCLUSION: Insulin resistance and endothelial dysfunction was elevated in prehyper-compared to normotension.KEYWORDS: prehypertension, insulin resistance, endothelial dysfunction, HOMA-IR, ADMA

Abstract

BACKGROUND: Along with the increase in obesity is a parallel increase in the prevalence of metabolic complications of obesity, often referred to as the metabolic syndrome (MetS). The role of adipose tissue in MetS has continued to evolve with the description of numerous secretory peptides from adipocytes named adipocytokines or adipokines. Recent studies have found visfatin as the regulation of inflammatory and immunomodulating prosesses, meanwhile adiponectin was known to have a potent anti-inflammatory properties. Here we try to assess the correlation between those two adipokines to MetS, via an inflammatory pathway.METHODS: This was a cross-sectional study on 128 non diabetic obese male subject (waist circumferences ≥90 cm). Visfatin and adiponectin were assessed by ELISA. Statistical analysis was performed using SPSS for Windows v.16.00 with signifcantly p<0.05. The correlations among biomarkers were assessed using Spearman's Rho test.RESULTS: This study showed a significant positive correlation between levels of visfatin and inflammatory markers TNF-α (r=0.22, p<0.005), and hsCRP (r=0.12, p=0.19), significant negative correlation between levels of adiponectin and TNF-α (r=-0.22-8, p<0.005-1), adiponectin and hsCRP (r=-0.14, p=0.11) and visfatin (r=-0.029, p<0.01). Plasma visfatin levels were increased along with the number MetS components, white plasma adiponectin showed inversely relation.CONCLUSION: Our present study has shown that visfatin has a proinflammatory properties and adiponectin has an anti-inflammatory properties, and how they have an opposite effects on MetS. Visfatin was found to have a positive correlaton while adiponectin was found to have a negative correlation with the number of MetS components.KEYWORDS: Obesity, Inflammation, Metabolic Syndrome, Adipocytokines, Visfatin, Adiponectin, TNF-α, hsCRP

Abstract

BACKGROUND: Visceral Obesity is related with chronic low grade inflammation, and is the main component of metabolic syndrome (MetS). MetS is associated with increased cardiovascular disease (CVD). Furthermore, superoxide dismutase (SOD) is correlated with insulin resistance. Several studies have reported a strong correlation between Renin Angiotensin Aldosterone System (RAAS) and CVD, but the association of Aldosterone, Plasma Renin Activity (PRA) and SOD with inflammation, insulin resistance and MetS have not been fully elucidated. The aim of this study was to investigate the correlation of Aldosterone, PRA, and SOD with inflammation (high sensitivity c-reactive protein/hsCRP) and insulin resistance (homeostasis model assessment-insulin resistance/HOMA-IR) in adult men with central obesity.METHODS: This was a cross-sectional study, which was carried out on 80 male subjects with central obesity who were divided into 2 groups: the group of subjects who had fulfilled the MetS criteria and the other group of subjects who did not. After an overnight fasting, blood pressure (BP) was measured on all subjects and laboratory examinations were done for measurement of the concentration of fasting glucose, high density lipoprotein cholesterol (HDL-C), triglyceride, hsCRP, insulin, aldosterone, PRA, and SOD.RESULTS: We found aldosterone had positive correlation with PRA (r = 0.389; p < 0.001) and triglycerides (r =0.234; p=0.036). PRA had positive correlation with SOD (r=0.220; p=0.05) and HDL-C (r=0.273; p=0.014), but not with hsCRP (r=-0.044; p=0.696) and HOMA-IR (r=0.168 p=0.136). PRA correlated with HOMA-IR in MetS (r=0.471; p=0.01). Aldosterone and PRA were correlated with diastolic pressure in those with hypertension (r=0.680; p=0.003 and r=0.608; p=0.01).CONCLUSIONS: There is no direct correlation between aldosterone or SOD and Insulin resistance, and inflammation in men with central obesity. The correlation between PRA and MetS might be through insulin resistance mechanism. We found significant correlation between PRA, HDL-C and SOD. Increased aldosterone was ccorrelated with elevated triglycerides, thus possibly increasing the risk of MetS.KEYWORDS: central obesity, aldosterone, plasma renin activity, superoxide dismutase, inflammation, insulin resistance

Abstract

BACKGROUND: Alpha-fetoprotein (AFP) has been used for hepatocellular carcinoma (HCC) diagnosis and screening, however, AFP has poor specificity. The extensive hypervascularity associated with HCC could be driven in part by the pro-angiogenic factor known as vascular endothelial growth factor (VEGF). Furthermore, invasiveness of certain HCC lesions has recently been linked to high levels of VEGF. Therefore, circulating VEGF levels of patients with liver cirrhosis (LC) and HCC were investigated and analysed.METHODS: An analytical cross sectional study was designed. Diagnosis of HCC and LC was performed using clinical criteria and findings obtained from B-mode ultrasonography (USG), computed tomography (CT) angiography, or magnetic resonance imaging (MRI). Blood were collected intravenously from all subjects. Obtained serum and plasma were stored in -80°C for following analyses: hepatitis B surface antigen (HBSAg), hepatitis C virus (HCV), alanine aminotransferase (ALT), total bilirubin, albumin, VEGF and AFP.RESULTS: Levels of VEGF and AFP were significantly higher in HCC group compared with LC group with p = 3.05 x 10-6 and p = 8.74 x 10-5, respectively. There was a significant positive correlation (p=0.029, r=0.309) between VEGF level and tumor size in HCC group. The area under curve (AUC) for VEGF level in HCC and LC groups was 0.771. In the level of median 435.6 pg/mL VEGF, the sensitivity was 50% and specificity was 86%. In the level of 199.99 pg/mL VEGF the sensitivity was 74% and specificity was 76%.CONCLUSION: The present findings suggested that VEGF level could be a useful marker for the presence of HCC in patients with LC.KEYWORDS: hepatocellular carcinoma, HCC, liver cirrhosis, LC, vascular endothelial growth factor, VEGF, alpha-fetoprotein, AFP

Abstract

BACKGROUND: Hypercholesterolemia is a major risk factor for coronary heart disease. Pharmacological treatment of  hypercholesterolemia are known to have side effects, hence the need for an alternative medicine, like herbal medicine, such as soybean as an example. Research objective is to compare the effects of ethanol extract, protein extract, and ethyl acetate fraction of soybean tempeh Detam-1 on the total serum cholesterol level of male mice.METHODS: This study was a laboratory experimental study with Completely Randomized Design (CRD) method. Twenty five balb-C strain male mice were allocated into five groups, namely: the negative-control (aquabidest), the positive-control (simvastatin), ethanol extract, protein extract and ethyl acetate fraction of the soybean tempeh Detam-1 and all were fed with high cholesterol containing food for 31 days. Starting on the 18th day all groups were treated for 14 days. The observed parameter was the total serum cholesterol level. The data of the study results were analyzed with ANOVA, followed by Tukey HSD test.RESULTS: There were significant differences between treatment groups and the negative-control (p=0.004). The reduction of the total cholesterol level of soy ethanol extract was 35.11±15%, the ethyl acetate fraction of soybean tempeh 26.48±17%, and soy protein extract was 15.33±33.1%, and no significant difference was noted in the positive-control group (simvastatin). CONCLUSION: The ethanol extract of soybean seed, protein extract of soybean seed, and ethyl acetate fraction of soybean tempeh Detam-1 have the same effect as do simvastin, and ethanol extract of soybean seed is the most effective substance for lowering total serum cholesterol in Balb-C male mice.KEYWORDS: hypericholesterolemia, ethanol extract, protein extract and ethyl acetate fraction, soybean Detam-1

Abstract

BACKGROUND: Typhoid fever has become one global health problem. Typhoid fever is caused by a Gram-negative bacterium, Salmonella typhi. Eel (Anguilla spp.) is a fish which lives in the sea or in freshwater. Several previous studies have found that Anguilla spp. mucus has the ability as antibacterial against Gram-positive and negative. Although the antibacterial activity of Anguilla spp. against various pathogens had been reported, very little is known about its activity against Salmonella typhi. The aim of this study was to investigate antibacterial activity of Anguilla spp. mucus against Salmonella typhi bacteria.METHODS: Present study was an experimental in vitro test. Antibacterial activity assays were carried out by the disc diffusion method. Antibacterial activity was determined by the clear zone formed around the paper disc and minimum inhibitory concentration was determined by observing the lowest concentration which could inhibit the growth of Salmonella typhi.RESULTS: Result of the present study showed that the Anguilla spp. mucus has inhibitory effects against Salmonella typhi. Minimum inhibitory concentration from the Anguilla spp. mucus was 12.5%.CONCLUSION: Anguilla spp. mucus has antibacterial activity against the Salmonella typhi bacteria.KEYWORDS: eel fish mucus, Anguilla spp., antibacterial activity, Salmonella typhi

Abstract

BACKGROUND: Recent clinical studies have suggested that γ-glutamyltransferase (γ-GT) can trigger oxidative stress within the plaque. This study aimed to investigate whether serum γ-GT might be as a risk factor of coronary heart disease (CHD), and measure the associations of serum γ-GT with high sensitive C-Reactive Protein (hs-CRP), Oxidized LDL (Ox-LDL) and Glutathione Peroxidase (GPx).METHODS: This study recruited 48 patients aged 30-70 year who underwent coronary angiography at Haji Adam Malik Medical Center at Medan between February and April 2008 and who presented at least one coronary stenosis of > 50% of the luminar diameter. The sample subjects were consecutively selected.RESULTS: γ-Glutamyltransferase was positively associated (r = 0.546) with hs-CRP as a marker of chronic inflammation after careful adjustment for other established risk factors in CHD patient. But, there was no significant difference between γ-GT in male and female patients. Further, there were no correlations between γ-GT and Ox-LDL and GPx. Ratio of γ-GT/GPx was measured as well, and it was associated with hs-CRP.CONCLUSIONS: Ratio of γ-GT/GPx was associated with inflammation process in coronary heart disease patients.KEYWORDS: γ-glutamyltransferase (γ-GT), inflammation, oxidative stress, coronary heart disease

Abstract

BACKGROUND: The prevailing view that eukaryotic cells are restrained from intercellular exchange of genetic information has been challenged by recent reports on nanotubes, exosomes, apoptotic bodies, and nucleic acid—binding peptides that provide novel pathways for cell—cell communication, with implications in health and disease.CONTENT: Microparticles (MPs) are a heterogeneous population of small plasma membrane structures that serve as important signaling structures between cells. MPs are composed of a phospholipid bilayer that exposes transmembrane proteins and receptors and encloses cytosolic components such as enzymes, transcription factors, and mRNA derived from their parent cells. Growing evidence suggests that MPs regulate inflammation, stimulate coagulation, affect vascular functions and apoptosis, and can also play a role in cell proliferation or differentiation. MPs circulate in the bloodstream, can be detected in the peripheral blood, and may originate from different vascular cell types (eg, platelets, monocytes, endothelial cells, red blood cells, and granulocytes).SUMMARY: Cells of various types release small membrane vesicles called MP on their activation, as well as during the process of apoptosis. The properties and roles of MP generated in different contexts are diverse and are determined by their parent cell and the pathway of their generation, which affects their content. MP are involved in multiple cellular functions, including immunomodulation, inflammation, coagulation, and intercellular communication. MPs are able to deliver molecular signals in the form of lipids, proteins, nucleic acids, or functional trans-membrane proteins from the parent cell to distantly located targets. From a clinical point of view, MP may serve as biomarkers for disease status and may be found useful for developing novel therapeutic strategies.KEYWORDS: microparticles, microvesicle, membrane remodeling, Intercellular communication

Abstract

BACKGROUND: Regardless of the precise underlying molecular mechanisms, the fundamental defining manifestation of aging is an overall decline in the functional capacity of various organs to maintain baseline tissue homeostasis and to respond adequately to physiological needs under stress. There is an increasingly urgent need for a more complete understanding of the molecular pathways and biological processes underlying aging and age-related disorders.CONTENT: Mitochondria constitute the most prominent source of adenosine triphosphate (ATP) and are implicated in multiple anabolic and catabolic circuitries. In addition, mitochondria coordinate cell-wide stress responses and control non-apoptotic cell death routines. The involvement of mitochondria in both vital and lethal processes is crucial for both embryonic and postembryonic development, as well as for the maintenance of adult tissue homeostasis. Age-associated telomere damage, diminution of telomere ‘capping’ function and associated p53 activation have emerged as prime instigators of a functional decline of tissue stem cells and of mitochondrial dysfunction that adversely affect renewal and bioenergetic support in diverse tissues. Constructing a model of how telomeres, stem cells and mitochondria interact with key molecules governing genome integrity, ‘stemness’ and metabolism provides a framework for how diverse factors contribute to aging and age-related disorders.SUMMARY: Cellular senescence defined as an irreversible proliferation arrest promotes age-related decline in mammalian tissue homeostasis. The aging of tissue-specific stem cell and progenitor cell compartments is believed to be central to the decline of tissue and organ integrity and function in the elderly. Taken into consideration that the overwhelming majority of intracellular reactive oxygen species (ROS) are of mitochondrial origin, it is reasonable to posit that the elevated ROS production might be caused by alteration in mitochondrial function during senescence. It is likely that mitochondria and stem cells will remain at the forefront of aging research also for the next decade.KEYWORDS: aging, stem cell, mitochondrial biogenesis, mitophagy, senescence, telomeres

Abstract

BACKGROUND: Ghrelin has many biological activities such as regulating energy homeostasis and recent studies have shown its effects in the cardiovascular system. Ghrelin concentration decreases in obese man that indicates relatioship between ghrelin and energy homeostasis. Ghrelin also improves endothelial function by increasing the bioavaibility of nitric oxide (NO). The bioavaibility of NO is also influenced by ADMA. ADMA is an endogenous competitive inhibitor of endothelial nitric oxide synthase (eNOS), which is significantly elevated during endothelial dysfuction. This study aimed to evaluate the relationship of ADMA and ghrelin with central obesity based on waist circumference and to evaluate the relationship of total ghrelin and ADMA in centrally obese men. METHODS: Total ghrelin and ADMA were measured in 20 non-obese men (waist circumference (WC) 78.85±4.40 cm) and 60 centrally obese men (WC 97.54±5.94 cm). Anthropometric measurements (height, weight, BM, waist circumference and blood pressure) were also recorded. Statistic were carried out by the Spearman and Pearson bivariate correlation analysis and independent sample T test. RESULTS: ADMA concentrations were significantly higher in centrally obese men than in normal weight controls (p-value <0.05), whereas total ghrelin concentrations were not significantly lower in centrally obese men than in normal weight controls (p-value >0.05). Ghrelin total concentrations were significantly lower in centrally obese men with metabolic syndrome than in normal weight controls (p-value <0.05). No significant correlation existed between total ghrelin and ADMA.CONCLUSIONS: No correlation existed between ADMA and total ghrelin. The pathway of ghrelin in altering vascular function may not involve ADMA.KEYWORDS: ghrelin, ADMA, endothelial dysfunction, obese
