Synergistic drug combinations enable enhanced therapeutics. Their discovery typically involves the measurement and assessment of drug combination index (CI), which can be facilitated by the development and applications of in-silico CI predictive tools. In this work, we developed and tested the ability of a mathematical model of drug-targeted EGFR-ERK pathway in predicting CIs and in analyzing m...

HGPS (Hutchinson-Gilford progeria syndrome) is a rare genetic disease affecting children causing them to age and die prematurely. The disease is typically due to a point mutation in the coding sequence for the nuclear intermediate-type filament protein lamin A and gives rise to a dominant-negative splice variant named progerin. Accumulation of progerin within nuclei causes disruption to nuclear...

Abstract Funding Acknowledgements Type of funding sources: None. Background Radiofrequency current remains one the most important ablation techniques in EP lab. Creating durable lesions is key to successful ablation. Evaluating lesion quality and progression growth difficult as many parameters influence formation. Therefore, several approaches were developed, monitoring RF duration, power conta...

A novel framework is introduced for the supervisory control (SC) of timed discrete event systems based on Time Petri nets. The method encompasses both logical (markings to reach or avoid) and temporal specifications (arrival departure times in specific markings). It relies construction a partial forward reachability graph modified state class type formulation integer linear programming problems...

Farnesyltransferase inhibitors (FTI) are a class of therapeutic agents designed to target tumors with mutations of the ras oncogene. However, the biological effect of FTIs is often independent of ras mutation status, which suggests the existence of additional mechanisms. In this study, we investigated the molecular effects of SCH66336, an FTI, in head and neck squamous cell carcinoma cells usin...

Patients with severe nonthyroidal illness (NTI) often have decreased serum thyroxin (T4) concentrations and sometimes have decreased free T4 (FT4) and increased tumor necrosis factor-alpha (TNF-alpha) concentrations. We evaluated four commercial methods for measuring FT4 [Abbott IMx, Amersham Amerlex MAB, Nichols, and Diagnostic Products Corporation (DPC) RIA] and one method for TNF-alpha in 41...

OBJECTIVE To determine whether and how protease inhibitors (PIs) could affect vascular aging. METHODS AND RESULTS HIV therapy with PIs is associated with an increased risk of premature cardiovascular disease. The effect of ritonavir and a combination of lopinavir and ritonavir (for 30 days) on senescence, oxidative stress, and inflammation was evaluated in human coronary artery endothelial ce...

BACKGROUND The purpose of our study was to investigate the association between polycystic ovary syndrome (PCOS) and hearing thresholds. MATERIAL AND METHODS Forty women diagnosed with PCOS (mean age, 24.33±6.38 years) and 40 healthy women controls (mean age, 26.38±6.75 years) were included in prospective study. Each case was tested with low (250, 500, 1000, and 2000 Hz), high (4000, 6000, and 8...

PURPOSE Prenylation is essential for membrane localization and participation of proteins in various signaling pathways. The following study was conducted to examine the importance of protein farnesylation and geranylgeranylation for the regulation of lymphoma cell survival and proliferation. EXPERIMENTAL DESIGN Lymphoma cells were treated with the beta-hydroxy-beta-methylglutaryl-CoA reductas...
