Abstract

BACKGROUND: Recent studies have indicated that lead may affect activities on bone cells, but the mechanism is not yet clear. Therefore, we conducted a study to investigate correlation of chronic low-concentration lead exposure with bone turnover activity (ratio of C-telopeptide (CTx) and Procollagen Type 1 Amino-terminal Propeptide (P1NP) (CTx/P1NP)) and antioxidant (aminolevulinic acid (ALA) dehydratase (ALAD)) in a workers community. METHODS: An observational study with cross-sectional design was carried out. Fifty two subjects from a workers community in Jakarta, Indonesia, had provided informed consents and undergone medical history, physical and laboratory examinations. Hair lead concentration was measured by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method. Meanwhile, P1NP was measured by Enzyme-linked immunosorbent assay (ELISA) and CTx was measured by Electro-chemiluminescence Immunoassay (ELICA) method.  RESULTS: The mean hair lead concentration was 4.85 ppm. Based on Mayo Clinic reference, 28.85% of investigated subjects had hair lead concentration of ≥5 ppm. Hair lead concentration was not correlated with ALAD, CTx, P1NP concentrations or CTx/P1NP. ALAD concentration was significantly correlated with CTx/P1NP (p<0.05; r=0.35).SUMMARY: ALAD concentration was correlated with CTx/P1NP ratio, indicating that the role of antioxidant was possibly caused by accumulated chronic low-concentration lead exposure, which was correlated with bone turnover activity. KEYWORDS: hair lead, ALAD, CTx, P1NP, osteoporosis, bone turnover

Abstract

BACKGROUND: Hypertension and central obesity are risk factors of cardiovascular disease. Epidemiology studies have shown that these two conditions are closely linked and often occur simultaneously. Inflammation is an underlying pathomechanism in hypertension and obesity. Vascular inflammation is related to coagulation pathway, whereby high level of inflammation increases the risk of atherothrombosis event. The aim of this study was to investigate the correlation between inflammation and fibrinolysis in hypertensive centrally obese subjects compared with hypertensive non obese sbjects.METHODS: This was a cross sectional study conducted in October 2009-June 2010 involving 53 eligible subjects according to the following criteria: men or women aged 30-65 years, had neither diabetes (FPG <126 mg/dL and or OGTT <200 mg/dL) nor CKD (eGFR ≥60 mL/minutes). All subjects were not in an acute inflammation state, had no unspecific infection (hs-CRP ≤10 mg/L), or taking anti-inflammation or anti-hypertensive medication.RESULTS: In this study we found that the levels of hs-CRP (2.636 mg/L vs 1.024 mg/L, p=0.007), PAI-1 (43.58 ng/mL vs. 28.43 ng/mL, p=0.089) and TAFI (12.73 ng/mL vs. 12.19 ng/mL, p=0.479) were respectively higher in hypertensive subjects with central obesity than in hypertensive subjects with no central obesity. In hypertensive centrally obese subjects there was significant positive correlation between hs-CRP and PAI-1 (r=0.491, p=0.001) and TAFI (r=0.312, p=0.0390, meanwhile in hypertensive non-obese subjects significant correlation was found only between hs-CRP and TAFI (r=0.929, p=0.003).CONCLUSIONS: Obesity in hypertensive subjects has higher inflammation state that is correlated with fibrinolysis disruption.KEYWORDS: hypertensive, obesity, hs-CRP, PAI-1, TAFI

Abstract

BACKGROUND: C-Reactive protein (CRP) and matrix metalloproteinase (MMP)-9 are inflammatory mediators that are often associated with the evolution of stroke. In this study, we aimed to find out whether concentration of these biomarkers were associated with the severity of discharge National Institute of Health Stroke Scale (NIHSS) in ischemic stroke patient.METHODS: In prospective stody, we involved 143 ischemic stroke patient who were admitted to hospital not more than 72 hours after the onset and who met the criteria. The concentration of CRP was assessed by High Sensitivity CRP reagent from Siemens and the concentration of MMP-9 was measure with Quantikine Human MMP-9 (total) Immunoassay from R&D. The outcome of stroke was determined by NIHSS score at discharge.RESULTS: There was a significant correlation between the CRP level and the severity of NIHSS at discharge (r = 0.288, p = 0.000). Subjects with intermediate/high level of CRP had a higher probability to have a moderate or even severe NIHSS (OR = 1.7, p = 0.004). Subjects with high MMP level showed a higher probability to have a severe NIHSS. CONCLUSION: The measurement of CRP and MMP-9 at 48-72 hours after stroke onset were associated with the severity of ischemic stroke based on NIHSS score at discharge.  KEYWORDS: inflammation, CRP, MMP-9, discharged NIHSS

Abstract

BACKGROUND: Mitochondrial function and behavior are central to the physiology of humans and, consequently, "mitochondrial dysfunction" has been implicated in a wide range of disease.CONTENT: Mitochondrial ROS might attack various mitochondrial constituents, causing mitochondrial DNA mutations and oxidative damage to respiratory enzymes. A defect in mitochondrial respiratory enzymes would increase mitochondrial production of ROS, causing further mitochondrial damage and dysfunction. Mitochondrial dysfunction is associated with diseases, such as neurodegenerative disorders, cardiomyopathies, metabolic syndrome, obesity, and cancer. Pathways that improve mitochondrial function, attenuate mitochondrial oxidative stress, and regulate mitochondrial biogenesis have recently emerged as potential therapeutic targets.SUMMARY: Mitochondria perform diverse yet interconnected functions, produce ATP and many biosynthetic intermediates while also contribute to cellular stress responses such as autophagy and apoptosis. Mitochondria form a dynamic, interconnected network that is intimately integrated with other cellular compartments. It is therefore not suprising that mitochondrial dysfunction has emerged as a key factor in a myriad of diseases, including neurodegenerative, cancer, and metabolic disorders. Interventions that modulate processes involved in regulation of mitochondrial turnover, with calorie restriction and induction of mitochondrial biogenesis, are of particular interest.KEYWORDS: mitochondrial biogenesis, mitochondrial dysfunction, reactive oxygen species (ROS), metabolic diseases

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: The mechanisms that are responsible for energy management in cells in an organism require a complex network of transcription of factors and cofactors.CONTENT: All living system must maintain a tight equilibrium between energy intake, storage and expenditure for optimal performance. This  tight equilibrium must be both robust and flexible to allow for adaptation to every situation such as exercise or rest and famine or feast. Organisms rely on finely tuned and complex signaling network to confront with all possibilities. Metabolic imbalance can cause dysfunction and pertubation of these networks, which if uncorrected will induce disease such as obesity and diabetes mellitus.SUMMARY: During the last decades the understanding of the transcriptional regulation of diverse metabolic pathways has contributed to the elucidation of mechanisms of metabolic control and to a better knowledge of the pathogenesis of metabolic diseases.

Abstract

BACKGROUND: Abortion remains a problem in the obstetric care as it is one of the causes of maternal and fetal death. Bleeding or miscarriage threat in the first trimester comprises 20% to 25% of all pregnant women, and 50% of them will end as spontaneous abortion. The major cause of maternal death in abortion is hemorrhage. Some recent studies have indicated that MMP-9 is important in the process of embryo implantation into the endometrium and spontaneous abortion occurs when there is an overwhelming increase of MMP-9. This data indicate the importance of a further research to elucidate the role of MMP-9 in spontaneous abortion.METHODS: This was a cross sectional study, included 70 pregnant women with gestational age <20 weeks who came for examination and treatment at the Department of Obstetrics and Gynecology, Medical Faculty of Padjadjaran University/Hasan Sadikin Hospital, Bandung. RESULTS: There were differences in the MMP-9 levels in spontaneous abortion compared to normal pregnancy and MMP-9 had a cut-off point >1221.7 with the sensitivity of 48.6% specificity of 80%, and accuracy of 60.9%.SUMMARY: The MMP-9 level in spontaneous abortion was higher than in normal pregnancy.KEYWORDS: MMP-9, spontaneous abortion, normal pregnancy

Abstract

BACKGROUND: Inflammation is a key component of the tumor microenvironment. Cancer-associated inflammation is marked by the presence of specific inflammatory cells and inflammatory mediators. Moreover, immune cells in the tumor microenvironment not only fail to mount an effective antitumor immune response, but also interact intimately with the tumor cells to actively promote oncogenesis.CONTENT: Their roles in regulating cytokine-dependent inflammation and immunity make the signal transducer and activator of transcription (STAT) proteins critical players in determining whether immune responses in tumor microenvironment promote or inhibit cancer. Recent evidence suggests a crucial role for STAT family proteins, especially STAT3 (signal transducer and activator of transcription 3), which is a point of convergence for numerous oncogenic signaling pathways, in selectively inducing and maintaining a procarcinogenic inflammatory microenvironment, both at the initiation of malignant transformation and during cancer progression. The persistent activation of STAT3 increases tumor cell proliferation, survival, and invasion while supressing antitumor immunity. SUMMARY: STAT3 signaling pathway constitutes a potential preventive and therapeutic target for cancer immunotherapy.  KEYWORDS: STAT3, inflammation, tumor microenvironment, cancer immunotherapy
