BACKGROUND: Intracameral Mydrane might facilitate a more streamlined cataract service and improve the patient experience. There is limited 'real-world' evidence of its use in a UK setting. METHODS: As part of a local evaluation of cataract surgery using intracameral Mydrane (group 2; n=60), data were collected on intraoperative pupil size and postoperative visual acuity (VA), as well as the rate of mechanical pupil dilation, intraoperative floppy iris syndrome (IFIS) and complications...

Precise control over the nucleation, growth, and termination of self-assembly processes is a fundamental tool for controlling product yield and assembly dynamics. Mechanisms for altering these processes programmatically could allow the use of simple components to self-assemble complex final products or to design processes allowing for dynamic assembly or reconfiguration. Here we use DNA tile self-assembly to develop general design principles for building complexes that can bind to a growing biomolecular assembly and terminate its growth by systematically characterizing how different DNA origami nanostructures interact with the growing ends of DNA tile nanotubes...

OBJECTIVE: Flexible nasolaryngoscopy (FNL) is considered the gold standard for evaluation of vocal fold mobility but there has been no data on the reliability of interpretation in the infant population. Visualization may be limited by excessive movement, secretions, or floppy supraglottic structures that prevent accurate diagnosis of vocal fold movement impairment (VFMI). We sought to evaluate the inter- and intra-rater reliability of FNL for the evaluation of VFMI in young infants. STUDY TYPE: Case-control...

Upon loading, atomic networks can feature delayed irreversible relaxation. However, the effect of composition and structure on relaxation remains poorly understood. Herein, relying on accelerated molecular dynamics simulations and topological constraint theory, we investigate the relationship between atomic topology and stress-induced structural relaxation, by taking the example of creep deformations in calcium silicate hydrates (C─S─H), the binding phase of concrete. Under constant shear stress, C─S─H is found to feature delayed logarithmic shear deformations...

Difficulty in tracheal intubation in paediatric intensive care patients is associated with increased morbidity and mortality. Delays to intubation and interruption to oxygenation and ventilation are poorly tolerated. We developed a safe and atraumatic tracheal intubation technique. A floppy-tipped guidewire and airway exchange catheter were placed to a pre-determined length under bronchoscopic guidance while oxygenation and ventilation was maintained via a supraglottic airway device (SAD). We performed a retrospective review of this technique on patients who were either known to have or who had an unexpected difficultly in intubation...

Inspired by earlier attempts in organic electronics aiming at controlling charge injection from metals into organic materials by manipulating the Schottky energy barrier using self-assembled monolayers (SAMs), recent experimental and theoretical work in molecular electronics showed that metal-organic interfaces can be controlled via changes in the metal work function that are induced by SAMs. In this paper we indicate a different route to achieve interface-driven control over the charge transfer/transport at the molecular scale...

BACKGROUND: It has been suggested that collagen abnormalities of the mitral valve are present in patients with floppy mitral valve (FMV)/mitral valve prolapse (MVP). Genetic factors determining collagen synthesis and degradation have not been well defined in these patients. This study was undertaken to determine whether selective polymorphisms of matrix metalloproteinase-2 (MMP2) or transforming growth factor-β (TGFβ), with known or putative effects on collagen turnover, are more frequent in FMV/MVP...

I was a second-year neonatal-perinatal fellow in a meeting between other members of the neonatal intensive care team and parents who had just received devastating news about their planned-for and highly desired baby, born after what had been an uncomplicated pregnancy. At home, a little sister was waiting to meet her new brother. These conversations are never easy, but this one I found particularly disturbing. John had been born at term via emergency cesarean section after his mother, Muriel, had come for a routine obstetrical visit and reported decreased fetal movement...

Infant botulism - why honey should be avoided for children up to one year Infant botulism means that Clostridium botulinum colonize and produce toxin in the infant gut, usually during the first year of life. Illness severity varies widely and the incidence may be under-estimated. Infant botulism should be considered in cases of acute muscle weakness or floppiness in infants, especially when accompanied by constipation or feeding difficulties. Respiratory failure and need for mechanical ventilation is common, but full recovery is gradually obtained...

REVIEW
Iker Valle Aramburu, Edward A Lemke
The nuclear pore complex (NPC) forms a permeability barrier between the nucleus and the cytoplasm. Molecules that are able to cross this permeability barrier encounter different disordered phenylalanine glycine rich nucleoporins (FG-Nups) that act as a molecular filter and regulate the selective NPC crossing of biomolecules. In this review, we provide a current overview regarding the interaction mechanism between FG-Nups and the carrier molecules that recognize and enable the transport of cargoes through the NPC aiming to understand the general molecular mechanisms that facilitate the nucleocytoplasmic transport...

With the goal of elucidating electronic and conformational effects on structure-spectroscopic property relationships in platinum acetylides, we synthesized a series of nominally centrosymmetric chromophores trans-Pt(PBu3)2(C≡C-Phenyl-X)2, where X = diphenylamino (DPA), NH2, OCH3, t-Bu, CH3, H, F, benzothiazole (BTH), CF3, CN, and NO2. We collected one- and two-photon absorption spectra and also performed density functional theory (DFT) and time-dependent (TD) DFT calculations on the ground- and excited-state properties of these compounds...

The use of atrial septal device occluders can lead to device embolization. This major complication can occur due to loose margins, deficient aorta, or thin and floppy posterior rim. Device embolization most often occurs after device release, and retrieval is essential. Many devices, including snare and bioptome, have been utilized for retrieval. However, performing these procedures can be difficult and time consuming. Failure to retrieve the embolized device requires open heart surgery. We report a novel and easy to perform method, "coronary wire trap technique," in the event of retrieval failure using conventionally available devices and snare, thereby preventing open-heart surgery...
