Abstract

BACKGROUND: Osteoprotegerin (OPG) is produced by a variety of tissues including those of the cardiovascular system. Recent clinical studies have suggested a significant correlation between elevated OPG serum level and cardiovascular mortality. Since coronary artery calcification (CAC) is positively associated with cardiovascular disease (CVD) events, we carried out a study to investigate whether OPG serum level is associated with the severity of CAC in non diabetic centrally obese men.METHODS: A cross sectional study was done on seventy non diabetic centrally obese men. CAC score was determined by using dual source computed tomography (DSCT). OPG serum level was measured by enzyme-linked immunosorbent assay (ELISA) method. Statistical analysis was done with SPSS for windows ver 16. ANOVA was performed to analyze mean, maximum, minimum value, and standard deviation. Spearman correlation test was performed to determine the correlation between OPG serum level and CAC score. Significance value was defined as alpha level=0.05 based on two-tailed tests.RESULTS: OPG serum level was significantly correlated with CAC score. The severity of CAC increased with the increase of OPG level. Age was significantly correlated with OPG serum level and CAC score.CONCLUSIONS: Our data show that serum OPG level was associated with the severity of CAC, which highlights that OPG could be involved in the progression of CAC in non diabetic obese men.KEYWORDS: obesity, vascular calcification, osteoprotegerin, coronary artery calcification

Abstract

BACKGROUND: Free radicals and antioxidant exist in balance under normal condition. In prooxidant condition, excessive free radicals can initiate a state of oxidative stress (OS) followed by capillary endothelial cell damage, a process involved in the pathophysiology of abortion.CONTENT: Abortion is a common complication of pregnancy and occurs in 25% of women. Many factors can cause abortion including fetal factor, implantation process and hormonal status. Combination those factors with OS influence the entire reproductive life of a woman. Antioxidant can neutralize free radicals and used to reduce OS especially in recurrent abortion.SUMMARY: Antioxidant therapy is a very interesting field in abortion especially used as prevention approach mainly caused by the high cost of infertility treatment methods.KEYWORDS: free radical, antioxidant, abortion

Abstract

BACKGROUND: Recent advances in our basic knowledge of the tissue damage and regeneration pathology have combined with a remarkable progress in stem cell biology so the prospect of clinical tissue repair strategies is a tangible reality. We tried to describe a better view about mesenchymal stem cell (MSC) mechanisms in wound healing and tissue regeneration, sending any ideas for next advanced therapies.CONTENT: Sustaining injury, whether minor or major, is part of every organism life. Therefore, efficient response mechanisms to damage have developed. Wound healing is a perplexing multi-step processes which can be divided into three major phases: inflammation, proliferation, and scar formation/remodeling. Though the compartementalization of this process into discrete stages give the illusion of simplicity, but in reality it is much more complicated. So that efficient healing can occur, complex interactions between multiple cell types, soluble factors and extracellular matrix components are required to rebuild the tissue. Even under optimal conditions, the healing process drives to fibrosis or scar. The latest technology that makes a huge difference in the wound healing process is stem cell therapy, which offers a novel approach to many diseases.SUMMARY: Wound healing therapies continue to rapidly evolve, with advances in basic science and engineering research heralding the development of new therapies, as well as ways to modify existing treatments. Stem cell-based therapy is one of the most promising therapeutic concepts for wound healing. Advances in stem cell biology have enabled researchers and clinicians alike with access to cells capable of actively modulating the healing response. KEYWORDS: wound healing, tissue regeneration, stem cells therapy

Abstract

BACKGROUND: The skin protects mammals from insults, infection and dehydration and enables thermoregulation and sensory perception. Various skin-resident cells carry out these diverse functions. Constant turnover of cells and healing upon injury necessitate multiple reservoirs of stem cells. The skin is a complex organ harboring several distinct populations of stem cells and a rich array of cell types. Advances in genetic and imaging tools have brought new findings about the lineage relationships between skin stem cells and their progeny. Such knowledge may offer novel avenues for therapeutics and regenerative medicine.CONTENT: In the past years, our view of the mechanisms that govern skin homeostasis and regeneration have markedly changed. New populations of stem cells have been identified that behave spatio-temporally differently in healthy tissues and in situations of damage, indicating that a great level of stem cell heterogeneity is present in the skin. There are believed to be distinct populations of stem cells in different locations. The lineages that they feed are normally constrained by signals from their local environment, but they can give rise to all epidermal lineages in response to appropriate stimuli. Given the richness of structures such as blood vessels, subcutaneous fat, innervation and the accumulation of fibroblasts under the upper parts of the rete ridges (in the case of human skin), it is reasonable to speculate that the microenvironment might be essential for interfollicular epidermal homeostasis. The bloodstream is probably the main source of long-range signals reaching the skin, and cues provided by the vascular niche might be essential for skin homeostasis.SUMMARY: A key function of the interfollicular epidermis is to act as a protective interface between the body and the external environment, and it contains several architectural elements that enable it to fulfill this function. All elements of the epidermis play active roles in regulating skin function, which might not have been anticipated from their role in maintaining skin integrity. Skin cell research benefits from the integration of complementary technologies and disciplines. How skin function is regulated and how it may be possible to intervene to treat a variety of skin conditions. Ultimately also impairing the maintenance of self-renewing satellite cells. Therefore, only anti-aging strategies taking both factors, the stem cell niche and the stem cells per se, into consideration may ultimately be successful.KEYWORDS: epidermis, hair follicle, fibroblast, skin stem cells, homeostasis, regeneration

Abstract

BACKGROUND: Visfatin is a novel adipokine secreted from visceral adipose tissue and has insulinomimetic properties. Visceral obesity is a risk factor for metabolic syndrome. Insulin resistance and inflammation are linked to visceral obesity and metabolic syndrome. Dysregulation of visfatin as an adipokine could play an important role in metabolic syndrome through insulin resistance and inflammation, or lower HDL cholesterol concentration. However, this need more evidence.METHOD: This was a crossectional study in 40 Indonesian obese men and 40 Indonesian obese women. Age: 30-60 years in men and 50-60 years for women, from February to March 2008 in Jakarta.RESULTS: No correlation between visfatin and hs-CRP as a marker of inflammation (r=0.190, p=0,101), or HOMA-IR as a marker of insulin resistance (r=-0.020, p=0.246). Suprisingly visfatin concentration is correlated with HDL Cholesterol (r=0.416, p=0.000).CONCLUSIONS: Visfatin plays an important role in metabolic syndrome through lipid metabolism. Positive correlation between visfatin and HDL cholesterol, was assumed that visfatin had a protective effect. Visfatin also known as as nicotinamide phosphoribosyltransferase (NAMPT) links Nicotinamide Adenine Dinucleotide (NAD) metabolism and raising of HDL Cholesterol. But the exact mechanisms need to be further studied.KEYWORDS: visceral obesity, metabolic syndrome, NAMPT, visfatin, HDL

Abstract

BACKGROUND: Increasing prevalence of obesity gives rise to many problems associated with multiple morbidities, such as diabetes, hypertension, heart disease, sleep apnea and cancer. The mechanism of obesity is very complex, thus its link to various disease is poorly understood. This review highlights important concepts in our understanding of the pathogenesis of obesity and related complications.CONTENT: Many studies have tried to explore the exciting and puzzling links between metabolic homeostasis and inflammatory responses. A form of subclinical, low-grade systemic inflammation is known to be associated with both obesity and chronic disease. This, later called as "metaflammation", refers to metabolically triggered inflammation. The nutrient-sensing pathway and the immune response coordination are facilitated by these molecular sites in order to maintain homeostasis under diverse metabolic and immune conditions. Recent studies have found that the NLRP3 inflammasome during metabolic stress forms a tie linking TXNIP, oxidative stress, and IL-1β production. This provides new opportunities for research and therapy for the disease often described as the next global pandemic: type 2 diabetes mellitus (T2DM).SUMMARY: The crucial role of metaflammation in many complications of obesity shown by the unexpected overlap between inflammatory and metabolic sensors and their downstream tissue responses. Then great interest arose to explore the pathways that integrate nutrient and pathogen sensing, give more understanding in the mechanisms of insulin resistance type 2 diabetes, and other chronic metabolic pathologies. A family of intracellular sensors called NLR family is a critical component of the innate immune system. They can form multiprotein complexes, called inflammasome which is capable of responding to a wide range of stimuli including both microbial and self molecules by activating the cysteine protease caspase-1, leading to processing and secretion of the proinflammatory cytokines IL-1β and IL-18, which play crucial roles in host defense. Inflammasome dysregulation has been linked to some autoinflammatory and metabolic diseases. These provide opportunities to continue to improve our understanding of the nature of metaflammation in the hope of modifying it to prevent and treat diseasese.KEYWORDS: Inflammation, metaflammation, inflammasome, metabolic disease, obesity

Abstract

BACKGROUND: Syntax score is a lesion-based angiographic scoring system, originally devised to grade the anatomic complexity of coronary artery disease (CAD) and thereby facilitate consensus in the study of a diagnostic angiogram between surgeons and interventional cardiologists. Suitable biology marker to predict the severity of CAD and to have a treatment decision for revascularization by percutaneous coronary intervention (PCI) or bypass surgery, is still unknown. Which biology marker can be a predictor for higher Syntax score remains unknown as well.METHODS: Severity of 105 patients who underwent coronary angiography, were evaluated with Syntax score. Laboratory tests were conducted for routine blood test, serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), high-sensitivity C-reactive protein (hs-CRP), total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, triglycerides, kidney function, creatinine and hemoglobin A1c (HbA1c).RESULTS: Ureum had significant correlation with Syntax score, p=0.016 and 95% confidence interval (CI)=0.05-0.55. Result of logistic regression analysis showed that HDL and haematocrit had significant correlation with Syntax score, with cut off point 34 (p=0.02, p=0.0033, respectively). Based on multi-variate analysis, Syntax score 34 = 16 (HDL ≤40 + Ureum ≥23) + 10 (Neutrophil/Lymphocyte ≥3.789) +10 (HbA1c ≥7 ) + 13 ( monocyte ≥9%).CONCLUSION: HDL cholesterol, ureum, neutrophil-lymphocyte ratio, HbA1c and monocyte altogether can predict the higher Syntax score.KEYWORDS: syntax, neutrophil, lymphocyte, HDL, cholesterol, ureum, HbA1c, monocyte

Abstract

BACKGROUND: Most medical treatments have been designed for the “average patients”. As a result of this “one-size-fits-all-approach”, treatments can be very successful for some patients but not for others. The issue is shifting by the new innovation approach in diseases treatment and prevention, precision medicine, which takes into account individual differences in people’s genes, environments, and lifestyles. This review was aimed to describe a new approach of healthcare performance strategy based on individual genetic variants.CONTENT: Researchers have discovered hundreds of genes that harbor variations contributing to human illness, identified genetic variability in patients’ responses to different of treatments, and from there begun to target the genes as molecular causes of diseases. In addition, scientists are developing and using diagnostic tests based on genetics or other molecular mechanisms to better predict patients’ responses to targeted therapy.SUMMARY: Personalized medicine seeks to use advances in knowledge about genetic factors and biological mechanisms of disease coupled with unique considerations of an individual’s patient care needs to make health care more safe and effective. As a result of these contributions to improvement in the quality of care, personalized medicine represents a key strategy of healthcare reform.KEYWORDS: precision medicine, genomic, proteomic, metabolomic

Abstract

BACKGROUND: Vascular remodeling was an adaptive process of the vascular wall that occured in response to long-term changes in hemodynamic conditions that contribute to the changes of the vascular structure and the pathophysiology of vascular disease. On the other hand, Endothelial Progenitor Cells (EPC) derived from bone marrow had the capacity to migrate to the peripheral circulation and to differentiate into mature endothelial cells. Therefore, EPC could contribute in the endothelial repairing after endothelial injury.METHODS: This study was a cross sectional design. Analysis was done among 30 subjects with normoalbuminuria normotension, 55 subjects with normoalbuminuria hypertension and 30 subjects with with microalbuminuria hypertension. TGF-β1, MMP-9 and VEGFR-2 testing were performed by ELISA method. All statistical calculations were performed using the SPSS 11.5 statistical software package. We used the Independent sample T test, Mann-Whitney, One Way Annova and Kruskal Wallis to establish the difference among various biochemical measures.RESULTS: TGF-β1 concentration was increased from normoalbuminuria normotension to normoalbuminuria hypertension and to microalbuminuria hypertension (27.63178±12.97246 vs. 38.61193±17.09546 vs. 38.73939±12.63911 ng/mL). TGF-β1 concentration was higher significantly in normotension as compared to hypertension (27.63178±12.97246 vs. 38.65692±15.58950, p<0.001) and to microalbuminuria hypertension (38.73939±12.63911, p<0.001). MMP-9 concentration was increased in normotension to normoalbuminuria hypertension but was decreased in microalbuminuria hypertension (438.1967±156.4268 vs. 564.5873±291.2876 vs. 418.6900±188.3801 ng/mL). MMP-9 concentration was higher significantly in normoalbuminuria hypertension as compared to microalbuminuria hypertension (p=0.028). VEGFR-2 concentration was decreased from normotension to normoalbuminuria hypertension to microalbuminuria hypertension (9.90552±1.85185 vs. 9.39561±1.75413 vs. 9.00506±1.47173 ng/mL). VEGFR-2 concentration was higher significantly in normotension as compared to microalbuminuria hypertension (p=0.042). CONCLUSIONS: The increasing concentration level of TGF-β1 and decreasing concentration level of MMP-9 in microalbuminuria hypertension showed that the remodeling process was getting increased. The decreasing concentration level of VEGFR-2 in microalbuminuria hypertension showed that the repairing process was getting decreased.KEYWORDS: vascular remodelling, vascular repairing, TGF-β1, MMP-9, VEGFR-2
