Vital Predictive and Prognostic Roles of Triglyceride-Glucose Index in Women With Acute Myocardial Infarction: A Retrospective Cohort Study.

Background And Aims: As a biomarker of insulin resistance (IR) in patients with acute myocardial infarction (AMI), the triglyceride-glucose index (TyG index) has received significant attention. However, most research on AMI has focused on male patients, as it is traditionally believed to primarily affect males. Therefore, this study was conducted on a female population with AMI to investigate the potential correlation between the TyG index and their outcomes.

Improving prediction of groundwater quality in situations of limited monitoring data based on virtual sample generation and Gaussian process regression.

A study of plasma kallikrein-deficient mice revealed increased aPTT, without prolonged bleeding time.

Assessment of cardiac safety for PPARγ agonists in rodent models of heart failure: a translational medicine perspective.

PPARγ-modulators, a class of anti-diabetic drugs as represented by thiazolidinediones (TZD), have been associated with cardiovascular risks in type-2 diabetes in humans but a similar liability has not been demonstrated in preclinical models. This gap between clinical and preclinical observations may reflect the lack of a translational model for cardiac safety assessment because preclinical efficacy for glycemic control for PPARγ-modulators is routinely conducted in animals with diabetic background while drug safety study is performed in young and health animals with little risk of heart failure, in contrast to the complex pathophysiological conditions of patients subjected to the treatment of TZDs. Therefore, some key steps are important to address this translational gap.

Multimodal biomarker investigation on efficacy and mechanism of action for the mammalian target of rapamycin inhibitor, temsirolimus, in a preclinical mammary carcinoma OncoMouse model: a translational medicine study in support for early clinical development.

We report on a biomarker-based translational medicine approach to assess the efficacy and mechanism of action for the mTOR inhibitor temsirolimus (CCI-779) in a mammary carcinoma OncoMouse model [polyomavirus middle T antigen (PyMT)]. The mTOR signaling pathway biomarkers were assessed using a reverse-phase protein array.

Effects of chronic rosiglitazone treatment on renal handling of salt and water in rats with volume-overload congestive heart failure.

Background: The side effects of fluid retention and edema of the thiazolidinedione (TZD) class of peroxisome proliferator-activated receptor-γ agonists limit their use in patients with congestive heart failure (CHF). The present study aims to explore whether chronic treatment with the TZD compound rosiglitazone (RGZ) is associated with worsening of salt and water retention in male Sprague-Dawley rats with aorto-caval fistula, an experimental model of volume-overload CHF.

Methods And Results: The effects of oral RGZ (30 mg/kg per day for 4 weeks) in CHF rats on plasma volume, cumulative sodium excretion, renal expression of Na(+) channels and transporters, and selected biomarkers of CHF were compared with those in CHF rats and sham-operated control rats treated with vehicle only (n=7 to 10).

Biomarkers of vulnerable atheromatous plaques: translational medicine perspectives.

In cardiovascular disease rupture of a vulnerable atherosclerotic plaque is the major causative factor of acute coronary syndromes, myocardial infarction and stroke, and can ultimately lead to death. Identification of biomarkers that could accurately predict the risk of plaque rupture would be a significant advance in guiding treatment of patients with this disease, The use of these biomarkers would also facilitate the development of new drugs to treat cardiovascular disease, particularly those that act through novel mechanisms. There is currently a lack of specific biomarkers for vulnerable plaque, and thus, it is an area of intense research including the concepts of live detection versus retrospective characterization, molecular imaging, and biochemical biomarker discovery.
