Current Caregiver Perspectives and Effects of Demographics on Family-Centered Rounds.

The 2010 Pediatric Research in Inpatient Settings survey stated that 44% of pediatric hospitals practiced family-centered rounds (FCRs). We aimed to study caregivers' opinions of FCRs and determine if there are demographic associations with these opinions. A cross-sectional survey of caregivers who attended FCRs was conducted at a tertiary-care general pediatrics unit.

Pediatric residents' perceptions of family-centered rounds as part of postgraduate training.

Purpose: Although family-centered rounds (FCRs) are recommended as standard practice, limited data address pediatric residents' opinions of FCRs. In the present study, we assessed residents' perceptions with respect to rounding experience and postgraduate year (PGY).

Methods: An anonymous online questionnaire was distributed to pediatric residents from nine accredited programs in New Jersey.

Tetrachelate porphyrin chromophores for metal oxide semiconductor sensitization: effect of the spacer length and anchoring group position.

Four Zn(II)-tetra(carboxyphenyl)porphyrins in solution and bound to metal oxide (TiO2, ZnO, and ZrO2) nanoparticle films were studied to determine the effect of the spacer length and anchoring group position (para or meta) on their binding geometry and photoelectrochemical and photophysical properties. The properties of three types of anchoring groups (COOH and COONHEt3) for four Zn(II)-porphyrins (Zn(II)-5,10,15,20-tetra(4-carboxyphenyl)porphyrin (p-ZnTCPP), Zn(II)-5,10,15,20-tetra(3-carboxyphenyl)porphyrin (m-ZnTCPP), Zn(II)-5,10,15,20-tetra(3-(4-carboxyphenyl)phenyl)porphyrin (m-ZnTCP2P), and Zn(II)-5,10,15,20-tetra(3-ethynyl(4-carboxyphenyl)phenyl)porphyrin (m-ZnTC(PEP)P)) were compared. In m-ZnTCPP, m-ZnTCP2P, and m-ZnTC(PEP)P the four anchoring groups are in the meta position on the meso-phenyl rings of the porphyrin macrocycle, thus favoring a planar binding mode to the metal oxide surfaces.

Binding studies of molecular linkers to ZnO and MgZnO nanotip films.

Two bifunctional linkers, a rigid-rod p-ethynyl-isophthalic acid capped with a Ru(II)-polypyridyl complex and 3-mercaptopropionic acid, were covalently bound to ZnO nanotip films grown by metal-organic chemical vapor deposition (MOCVD) technology. This highly vertically aligned, crystalline form of ZnO had not been functionalized before. The binding was studied by Fourier transform (FT) IR and UV spectroscopies and probed, in the case of the Ru complex, by static and dynamic fluorescence quenching.
