Primary Ciliary Dyskinesia: A Suggested Pathway to Transition From Pediatric to Adult Care. [PDF]

Pediatr Pulmonol
ABSTRACT Primary ciliary dyskinesia (PCD) is a rare, genetically heterogeneous disorder characterized by motile ciliary dysfunction that impairs mucociliary clearance. Symptoms of PCD can include unexplained neonatal respiratory issues, chronic sino‐otopulmonary symptoms, recurrent infections, bronchiectasis, and subfertility.

Revision of the crystal structure of `bis(glycine) squaric acid'

IUCrData, 2018
The crystal structure of `bis(glycine) squaric acid' [Tyagi et al. (2016). RSC Adv. 6, 24565–24576], is revised. Re-refinement of the structure against the original X-ray intensity data after correct placement of the donor H atoms proves that the ...

Crystal structures of cristobalite-type and coesite-type PON redetermined on the basis of single-crystal X-ray diffraction data

Acta Crystallographica Section E: Crystallographic Communications, 2015
Hitherto, phosphorus oxonitride (PON) could not be obtained in the form of single crystals and only powder diffraction experiments were feasible for structure studies.

The crystal structure of BaH6As4O14 redetermined, revealing the localization of the hydrogen atoms

IUCrData, 2019
The crystal structure of barium hexahydrogen cyclo-tetradecaoxidotetraarsenate(V), was redetermined. In comparison with the previous determination [Blum, Durif & Guitel. (1977). Acta Cryst. B33, 3222–3224] the positions of the hydrogen atoms were located,

New refinement of the crystal structure of Zn(NH3)2Cl2 at 100 K

Acta Crystallographica Section E: Crystallographic Communications, 2019
The crystal structure of [ZnCl2(NH3)2], diamminedichloridozinc, was re-investigated at low temperature, revealing the positions of the hydrogen atoms and thus a deeper insight into the hydrogen-bonding scheme in the crystal packing.
