ATX is a secreted enzyme that produces lysophosphatindic acid (LPA) in plasma. For several years investigators have characterized endogenous factors that regulate ATX expression and compartmentalization. However many questions remain unanswered and this article highlights our recent finding that autotaxin (ATX) is readily induced by toxic environmental chemicals. LPA binds G-protein coupled rec...
Diisocyanates (dNCOs) are low molecular weight chemical sensitizers that react with autologous proteins to produce neoantigens. dNCO-haptenated proteins have been used as immunogens for generation of dNCO-specific antibodies and as antigens to screen for dNCO-specific antibodies in exposed individuals. Detection of dNCO-specific antibodies in exposed individuals for diagnosis of dNCO asthma has...
BACKGROUND Echocardiography is a key screening tool in the diagnostic algorithm of pulmonary hypertension (PH). In addition, tissue doppler imaging (TDI) is a promising method for the noninvasive estimation of pulmonary artery pressure (PAP). OBJECTIVES The aim of this study was to validate the accuracy of measuring the time from the beginning of the right ventricular isovolumetric contractio...
OBJECTIVE In this study we assess the value of left atrial dyssynchrony time measured by tissue Doppler imaging (TDI) to predict recurrences after pulmonary vein isolation (PVI) in patients with paroxysmal and persistent atrial fibrillation (AF). METHODS One hundred sixty patients (57 ± 7.5 years, 122 males) with symptomatic drug-refractory paroxysmal and persistent AF, undergoing PVI were en...
We report on the first demonstration of time-delay interferometry (TDI) for LISA, the Laser Interferometer Space Antenna. TDI was implemented in a laboratory experiment designed to mimic the noise couplings that will occur in LISA. TDI suppressed laser frequency noise by approximately 10(9) and clock phase noise by 6×10(4), recovering the intrinsic displacement noise floor of our laboratory tes...
Iread with interest the Case Report on intestinal obstruction due to acute toluene 2,4-diisocyanate (TDI) exposure recently published in The IJOEM. Although considering occupational and environmental etiologies in the clinical assessment of the patient is admirable, some important clues of occupational history have not yet been clarified. Characteristics of an exposure are very important: Was t...
This paper describes our experience with the respiratory effects of TDI. Five respiratory reactions attributable to TDI are described with supporting evidence. The reactions are sensitization, irritation from overexposure, acute loss of ventilatory capacity, accelerated loss of pulmonary function and induction of a general asthmatic state. Evidence is presented that suggests a safe exposure level.
Background Not much is known about the health seeking behavior of people with substance use disorders before they enter specialized treatment and afterwards. This paper explains in detail the protocol that has been followed to establish the Belgian TDI-IMA-database, which is linking two separate databases: the Treatment Demand Indicator (TDI) and the database of the Intermutualistic Agency (IMA...
Traumatic Dental Injury (TDI) is often caused by a bruise from a sports-related incident or fall. In individuals with maxillary protrusion, the risk for TDI may be higher. We treated a patient with Hereditary Gingival Fibromatosis (HGF), a rare genetic disorder characterized by proliferative fibrous overgrowth of gingival tissue, who subsequently received a TDI after periodontal surgery. A 13-y...
We sought to investigate variation of atrial electromechanical interval after catheter ablation procedure in patients with persistent atrial fibrillation using pulse Doppler (PW) and pulse tissue Doppler imaging (PW-TDI). A total of 25 consecutive in-patients with persistent atrial fibrillation, who restored sinus rhythm after ablation procedure, were recruited in our cardiac center. Echocardio...
