Objective: To evaluate the outcomes of children with vesicoureteral reflux (VUR) and obstructive megaureter (OM) utilizing various laparoscopic and robot-assisted approaches.
Materials And Methods: Retrospective review of all pediatric laparoscopic and robot-assisted cases for lower ureter pathology was performed between 2016-2022 in 13 academic centers worldwide. Five surgical approaches were assessed: LEUR, LVCUR, LDECUR, RALUR, and RADECUR.
We present a theoretical study of the effects of collisions with water vapor molecules on the absorption, around 4 μm, in both the high frequency wing of the CO ν band and the collision-induced fundamental band of N. Calculations are made for the very first time, showing that predictions based on classical molecular dynamics simulations enable, without adjustment of any parameter, very satisfactory agreement with the few available experimental determinations. This opens the route for a future study in which accurate temperature-dependent (semi-empirical) models will be built and checked through comparisons between computed and measured atmospheric spectra.

Quantum chemical calculations were performed in the space of five intermolecular coordinates and varying N--N bond length using Møller-Plesset perturbation and CCSD(T) methods with extrapolation of the electronic energy to the complete basis set. This made it possible to construct the intermolecular potential energy surface and to define the surface of the N--N dipole derivative with respect to internal coordinate.

The pure water vapour and water-nitrogen continuum absorption in the 1000 and 2500 cm(-1) atmospheric windows has been studied using a 2 m base-length White-type multi-pass cell coupled with a BOMEM DA3-002 Fourier transform infrared spectrometer. The measurements were carried out at the National Institute of Standards and Technology (NIST, Gaithersburg, MD) over the course of several years (2004, 2006-2007, 2009). New data on the H(2)O:N(2) continuum in the 1000 cm(-1) window are presented and summarized along with the other experimental results and the continuum model.

The peptide adopts a disulfide-stabilized α-helical hairpin structure in aqueous solution and thus represents a novel fold among naturally occurring antimicrobial peptides. Micromolar concentrations of EcAMP1 were shown to inhibit growth of several fungal phytopathogens.
