The incremental benefit of emergency medical services (EMS) activation of the cardiac catheterization laboratory (CCL) for ST-elevation myocardial infarction (STEMI) in the setting of an established in-house interventional team (IHIT) is uncertain. We evaluated the impact of EMS activation on door-to-balloon (D2B) time and first medical contact-to-balloon (FMC2B) time for STEMI when coupled with a 24-hour/day IHIT. All patients presenting with STEMI to Loyola University Medical Center had demographic, procedural, and outcome data consecutively entered in a STEMI Data Registry.

Objective: Children in early learning settings are vulnerable to site-specific emergencies because of physical and developmental limitations. We examined parents' knowledge of disaster plans in their child's early learning settings.
Methods: In May 2015, we conducted a nationally representative online household survey, including parents of children ages 0-5 years in child care settings.
Objective: Children's summer camps are at risk for multiple pediatric casualties during a disaster. The degree to which summer camps have instituted disaster preparedness is unknown. We assessed disaster preparedness among selected camps nationally for a range of disasters.

Rapid diagnosis in the Emergency Department could significantly improve patient outcomes. We describe the diagnosis of such a lesion through the use of ultrasound imaging in the Emergency Department to utilize a fast, cost-effective imaging technique that does not subject the patient to radiation exposure.

The compounds contain a p-anisylbenzimidazolecarboxamido (Hx) moiety attached to a PP, IP, or PI unit, giving compounds HxPP (2), HxIP (3), and HxPI (4), respectively. These fluorescent hybrids were tested against their complementary nonfluorescent, non-formamido tetraamide counterparts, namely, PPPP (5), PPIP (6), and PPPI (7) (cognate sequences 5'-AAATTT-3', 5'-ATCGAT-3', and 5'-ACATGT-3', respectively).
View Article and Find Full Text PDFImidazole and pyrrole-containing polyamides belong to an important class of compounds that can be designed to target specific DNA sequences, and they are potentially useful in applications of controlling gene expression. The extent of polyamide curvature is an important consideration when studying the ability of such compounds to bind in the minor groove of DNA. The current study investigates the importance of curvature using polyamides of the form f-Im-Phenyl-Im, in which the imidazole heterocycles are placed in ortho-, meta-, and para-configurations of the phenyl moiety.

Even though various designs of polyamides have been thoroughly investigated for DNA sequence recognition, the use of H-pin polyamides (covalently cross-linked polyamides) has not received as much attention. Therefore, experiments were designed to systematically investigate the DNA recognition properties of two symmetrical H-pin polyamides composed of PyImPyIm (5) or f-ImPyIm (3e, f=formamido) tethered with an ethylene glycol linker.

These compounds were synthesized with the aim of attaining a higher level of sequence selectivity over f-ImPyIm (1), a previously published strong minor-groove binder. Two compounds possessing a furan or a benzofuran moiety at the N-terminus showed a footprint of 0.

ITC studies showed that f-IPI (1) bound to the cognate site (ACG( *)CGT) with only 3.5-fold lower affinity than binding to the unlabeled DNA (ACGCGT) (K(eq)=2 x 10(7) and 7 x 10(7)M(-1), respectively).
View Article and Find Full Text PDFAn N-formamido pyrrole- and imidazole-containing triamide (f-PIP) has been shown by DNase I footprinting, SPR, and CD studies to bind as a stacked dimer to its cognate sequences: 5'-TACGAT-3' (5'-flank of the inverted CCAAT box-2 of the human topoisomerase IIalpha promoter) and 5'-ATCGAT-3'. A gel shift experiment provided evidence for f-PIP to inhibit protein-DNA interaction at the ICB2 site. Western blot studies showed that expression of the topoisomerase IIalpha gene in confluent NIH 3T3 cells was induced by treatment with f-PIP.
