Triglyceride-Glucose Index As A Biomarker Of Insulin Resistance, Diabetes Mellitus, Metabolic Syndrome, And Cardiovascular Disease: A Review.

The triglyceride-glucose (TyG) index is one of the parameters that have been used in assessing insulin resistance. Triglycerides and fasting blood glucose are two low-cost, common laboratory indicators that are used to compute the TyG index. This article reviews the link between the TyG index and several aspects concerning insulin resistance-related disorders and cardiovascular disease, as well as the use of various TyG index cutoffs in the above conditions with sensitivity and specificity, respectively, in various populations in the world.

Glycemic control as the main determinant factor of serum VEGF levels in type 2 diabetes mellitus patients.

Diabetes mellitus (DM) is a main endocrine disorder that may cause vascular complications as the disease progresses. Vascular endothelial growth factor (VEGF) has been linked to the development of micro and macrovascular diabetic complications. This study aimed to assess several factors including blood pressure, body mass index, lipid profile, kidney function, and glycemic control that may provide the rise of serum VEGF levels in type 2 DM subjects.

Role of Soluble Transferrin Receptor - An Iron Marker in Hemodialysis Patients.

Background: Iron status assessment is crucial in end-stage renal disease hemodialysis (ESRD-HD) patients because iron deficiency may cause unresponsiveness to erythropoiesis-stimulating agent. Soluble transferrin receptor (sTfR) is a potential iron marker that is not influenced by inflammation, and the results among studies are still conflicting. This study evaluated the role of sTfR in determining iron deficiency in ESRD-HD patients.

Lipocalin 2 could predict circulating MMP9 levels in patients with breast cancer.

Objectives: Breast cancer is the most prevalent carcinoma found in Indonesian women, and its incidence remains high worldwide. Lipocalin 2 has been linked with the progression of breast cancer. Matrix metalloproteinase 9 (MMP9) is an enzyme that has an important role in angiogenesis.

Anthropometric features in predicting insulin resistance among non-menopausal Indonesian adult females.

Introduction: The prevalence of obesity is increasing worldwide in high, low, and middle-income countries such as Indonesia. Obesity rate is higher in females in Indonesia. Obesity has important contribution in the occurrence of insulin resistance (IR) and type 2 diabetes mellitus.

Insulin resistance and testosterone level in Indonesian young adult males.

Introduction: Central obesity is characterized by the accumulation of abdominal fat which may lead to several diseases including insulin resistance. The prevalence of central obesity is higher in male and the incidence in young adult males is increased. Central obesity is also related to low testosterone levels.

Victims of Physical Violence Have a Higher Risk to Be Perpetrators: A Study in High School Students Population.

Background: Violence experienced by a person can trigger mental disorders. It was reported that 1 in 4 children in the world had experienced severe and sustained physical violence. The form of violence varies from various bullying actions that seem mild, to deadly physical violence.

Body Mass, Total Body Fat Percentage, and Visceral Fat Level Predict Insulin Resistance Better Than Waist Circumference and Body Mass Index in Healthy Young Male Adults in Indonesia.

The incidence of obesity which leads to insulin resistance (IR) and metabolic disorder is increasing in developing countries, including Indonesia. Male adults have a higher risk of abdominal obesity than females. This is associated with cardiometabolic disorders.

Wheat gluten-based renewable and biodegradable polymer materials with enhanced hydrophobicity by using epoxidized soybean oil as a modifier.

Epoxidized soybean oil (ESO) was applied as an additive for wheat gluten (WG) to modify the properties of the renewable and biodegradable natural polymer materials. Optimum intermolecular interactions and crosslinking between ESO chains and the WG matrix were achieved under alkaline conditions. The WGESO materials were heterogeneous on a scale of 20-30 nm, but the homogeneity was improved upon increasing the amount of glycerol as a plasticizer in the materials.

Formation of wheat-protein-based biomaterials through polymer grafting and crosslinking reactions to introduce new functional properties.

An insoluble wheat proteins-based polymer networks with new functional groups and positive charges were prepared through grafting-coupling reactions. The networks were also flexible with a lower glass transition temperature since the existence of the grafted mobile segments. The multi-component/multi-phase systems became relatively homogeneous on a scale of 20-30 nm due to strong intermolecular interactions and chemical cross-linking in the materials.

Chemical modification of wheat protein-based natural polymers: grafting and cross-linking reactions with poly(ethylene oxide) diglycidyl ether and ethyl diamine.

Mobile poly(ethylene oxide) diglycidyl ether (PEODGE) segments were chemically grafted onto a soluble wheat protein (WP), and different network structures were formed via coupling reactions with ethyl diamine (EDA) in different PEODGE/EDA (PE) ratios. When the PE ratio was 1:1, linear PEs were the predominant segments grafted onto WP chains and the whole WP-PEODGE-EDA (WPE) system was still soluble with an increased molecular weight. Reducing the amount of EDA in the systems produced insoluble cross-linked WPE networks.

Imported malaria in Jakarta, Indonesia: passive surveillance of returned travelers and military members postdeployment.

Background: Autochthonous malaria does not currently occur in Jakarta, the most populous city in Indonesia. Military, forestry, mining, and tourist activities draw Jakarta residents to distant parts of the archipelago with high rates of malaria. Although malaria is a reportable disease in Jakarta, little has been published.

Rapid onset of transmission-reducing antibodies in javanese migrants exposed to malaria in papua, indonesia.

Transmission of Plasmodium falciparum malaria is initiated by sexual stages in the mosquito. Anti-Pfs48/45 and anti-Pfs230 sexual stage antibodies that are ingested together with parasites can reduce parasite development and subsequently malaria transmission. Acquisition of sexual stage immunity was studied in a cohort of 102 non-immune Javanese individuals migrating to hyperendemic Papua Indonesia.

Differential recognition of microfilarial chitinase, a transmission-blocking vaccine candidate antigen, by sera from patients with Brugian and Bancroftian filariasis.

We examined the reactivity of human sera with recombinant microfilarial chitinase and with the antigenic determinant on the native parasite molecule identified by monoclonal antibody (MAb) MF1. In Brugian filariasis, the MF1 epitope is preferentially recognized by residents of endemic areas who remain amicrofilaremic and asymptomatic despite lifelong exposure to filarial worms. Reactivity with filarial chitinase and its MF1 epitope inversely correlates with microfilaremia levels in Bancroftian filariasis and is associated with a prolonged amicrofilaremic state following a single course of treatment with diethylcarbamazine.

Evaluation of a recombinant parasite antigen for the diagnosis of lymphatic filariasis.

We evaluated the usefulness of a recombinant parasite antigen (recSXP1) for the serologic diagnosis of lymphatic filariasis. A large proportion of sera from microfilaremic donors living in five different endemic countries (356 of 446 [80%]) contained IgG antibodies to recSXP1, as do sera from approximately 33% of amicrofilaremic patients with acute filarial disease and/or indirect evidence of active filarial infection. Exposure to filarial worms per se does not appear sufficient to elicit an anti-SXP1 antibody response.

Differential recognition of microfilarial antigens by sera from immigrants into an area endemic for brugian filariasis.

Studies in animal models indicate that antibodies to surface antigens of microfilariae participate in the control of parasitaemia resulting from infections with lymphatic filarial nematodes. In an attempt to identify parasite antigens that elicit such 'protective' host responses, we compared the antigen recognition patterns of persons who remained amicrofilaraemic after 3-6 years of exposure to Brugia malayi with those of individuals who developed patent filariasis during the same period. IgG antibodies in sera from immigrants identified between 0 and 25 microfilarial antigens on Western blots.

Immune response of humans to the circumsporozoite protein of Plasmodium falciparum: limited T cell response to the immunodominant central repeat region.

Most adults in highly malarious areas have antibodies to the repeat region of the circumsporozoite protein of Plasmodium falciparum. To determine if a T cell epitope on the repeat region stimulated T cell help for this antibody, we used R32tet32, a recombinant construct derived from the repeat region of the circumsporozoite protein of P. falciparum, to stimulate in vitro mononuclear cells from residents of an area hyperendemic for malaria.

Regulation of immune responses in lymphatic filariasis.

The nature and intensity of immune reactions to filarial antigens appear to be controlled by two broad mechanisms: immunoregulation and immune tolerance. Parasite molecules of high molecular weight activate suppressor T lymphocytes; suppressive parasite products are present in sera from microfilaraemic patients. Prenatal or perinatal exposure to soluble parasite antigens may influence a person's future ability to react to filarial antigens.

In vitro growth inhibition of Plasmodium falciparum by sera from tropical splenomegaly syndrome patients.

Sera from tropical splenomegaly syndrome (TSS) and non-TSS patients from the same village were examined for their ability to inhibit the in vitro growth of Plasmodium falciparum. Using synchronized malaria cultures, sera from both groups inhibited parasite development only if added before merozoite reinvasion of erythrocytes had occurred. There was no significant difference in the degree or apparent mechanism of inhibition caused by TSS and non-TSS sera.

Identification of Brugia malayi in vectors with a species-specific DNA probe.

We evaluated the potential value of a cloned sequence of genomic DNA of Brugia malayi as a species-specific probe. Clone pBm 15 reacted with all stages of 8 different geographic isolates of B. malayi and cross-hybridized with microfilariae of B.

Antibody-mediated killing of suppressor T lymphocytes as a possible cause of macroglobulinemia in the tropical splenomegaly syndrome.

To investigate the pathogenesis of macroglobulinemia in the tropical splenomegaly syndrome (TSS), we assessed the functional activity of B lymphocytes and T cell subsets in a pokeweed mitogen-driven assay of immunoglobulin synthesis. Mononuclear cells from patients with TSS produced more IgM than cells from village or from distant controls. This appeared to result from a decrease in the number and/or activity of suppressor T cells of the T8+ phenotype.
