The prevalence studies on specific IgE to toluene diisocyanate (TDI)-human serum albumin (HSA) conjugate in TDI-induced asthma have shown variable results. In this study, we attempted to compare specific IgE bindings to TDI-HSA conjugate and its specificity using 3 different conjugates. Sera were collected from 20 TDI-induced asthma and 10 controls. Specific IgE were measured by ELISA using thr...

Time-dependent inhibition (TDI) of cytochrome P450 enzymes is an important cause of drug-drug interactions. The standard approach to characterize the kinetics of TDI is to determine the rate of enzyme loss, kobs, at various inhibitor concentrations, [I], and replot the kobs versus [I] to obtain the key kinetic parameters, KI and kinact. In our companion manuscript (Part 1; Nagar et al., 2014) i...

Hypertrophic cardiomyopathy (HCM) in cats is characterized by concentric left ventricular (LV) hypertrophy and both diastolic and systolic dysfunction. Although impaired cardiac function detected by tissue Doppler imaging (TDI) in cats with HCM was previously reported, reference ranges of TDI in normal cats and cats with HCM have been reported as widely variable. Two-dimensional speckle trackin...

Time-dependent inhibition (TDI) of cytochrome P450 (P450) enzymes, especially CYP3A4, is an important attribute of drugs in evaluating the potential for pharmacokinetic drug-drug interactions. The analysis of TDI data for P450 enzymes can be challenging, yet it is important to be able to reliably evaluate whether a drug is a TDI or not, and if so, how best to derive the inactivation kinetic par...

β-Cyclodextrin-ionic liquid polymer (CD-ILP) was first synthesized by functionalized β-cyclodextrin (CD) with 1-benzylimidazole (BIM) to form monofunctionalized CD (βCD-BIMOTs) and was further polymerized using a toluene diisocyanate (TDI) linker to form insoluble CD-ILP (βCD-BIMOTs-TDI). The βCD-BIMOTs-TDI polymer was characterized using various tools and the results obtained were compared wit...

The objective of this study was to assess the association of untreated traumatic dental injuries (TDI) with individual-, sociodemographic- and school-related factors among 12-year-old schoolchildren in Midwest Brazil. This cross-sectional study was carried out in 2010 in the city of Goiania, Brazil. A random sample of 2075 schoolchildren was examined and interviewed. Untreated TDI in the perman...

AIMS Preliminary studies suggested that tissue Doppler imaging (TDI) was able to identify mutation carriers in familial hypertrophic cardiomyopathy (HCM) before the development of hypertrophy. However, data are limited. We performed a systematic analysis of echocardiography, TDI, and electrocardiogram (ECG) in familial HCM to identify parameters associated with genetic status. METHODS AND RES...

INTRODUCTION In this cross-sectional study, the level of knowledge and attitude of elementary school teachers regarding traumatic dental injuries (TDI) were assessed. MATERIALS AND METHODS A questionnaire was distributed to 330 elementary school teachers in 30 randomly selected schools in the Emirates of Sharjah and Dubai. The questionnaire collected information on participants' demographic c...

Global and regional left ventricular (LV) systolic dysfunction is a marker of coronary artery disease (CAD), which is conventionally assessed using two-dimensional echocardiography. Tissue Doppler imaging (TDI) has emerged as an adjunct tool in the diagnosis of regional wall motion abnormalities from CAD. We performed a systematic review and meta-analysis to assess the efficacy of TDI indices i...

Toluene diisocyanate (TDI)-induced airway disease is a disorder characterized by chronic airway inflammation and airway remodeling. A recently discovered group of cytokines is the IL-17 family, which has been introduced as an important regulator of immune and inflammatory responses, including airway inflammation. Recently, we have reported that phosphatase and tensin homologue deleted on chromo...
