Bilateral superior rectus transposition with bilateral medial rectus recession has been described successfully for treatment of Duane's syndrome but never for Möbius syndrome. The authors describe a child with Möbius syndrome who presented with large bilateral abduction deficits and esotropia. This surgical treatment resulted in marked improvement of said deficits.

INTRODUCTION: Möbius syndrome is defined as a combined congenital bilateral facial and abducens nerve palsies. The main goal of treatment is to provide facial reanimation by means of a dynamic surgical procedure. The microneurovascular transfer of a free muscle transplant is the procedure of choice for facial animation in a child with facial paralysis. OBSERVATION: Between January 2008 and January 2017, 124 patients with the syndrome have been approached at our institution...

In this minireview, we report on our year-long EPR work, such as electron-nuclear double resonance (ENDOR), pulse electron double resonance (PELDOR) and ELDOR-detected NMR (EDNMR) at X-band and W-band microwave frequencies and magnetic fields. This report is dedicated to James S. Hyde and honors his pioneering contributions to the measurement of spin interactions in large (bio)molecules. From these interactions, detailed information is revealed on structure and dynamics of macromolecules embedded in liquid-solution or solid-state environments...

Filamentous bacteriophages such as fd-like viruses are monodisperse rod-like colloids that have well defined properties: diameter, length, rigidity, charge and chirality. Engineering those viruses leads to a library of colloidal rods which can be used as building blocks for reconfigurable and hierarchical self-assembly. Their condensation in aqueous solution with additive polymers which act as depletants to induce attraction between the rods leads to a myriad of fluid-like micronic structures ranging from isotropic/nematic droplets, colloid membranes, achiral membrane seeds, twisted ribbons, $\pi$-wall, pores, colloidal skyrmions, Möbius anchors, scallop membranes to membrane rafts...

Moebius/Mӧbius Syndrome (MS) is an extremely rare congenital disorder characterized by uni- or bilateral palsy of the abducens (VI) and the facial (VII) nerves, causing facial paralysis. Dysfunction of cranial nerves III through XII is common, most often the glossopharyngeal (IX) and hypoglossus (XII). Afflicted individuals seeking prosthodontic care, particularly removable prosthetics, present multiple challenges related to inherent facial and tongue muscle weakness and microstomia. Other extraoral anomalies may include congenital multiple arthrogryposis and malformations of the upper and lower limbs...

Möbius' syndrome, also known as Möbius' sequence, is a nonprogressive cranial dysinnervation disorder characterized by congenital facial and abducens nerve paralysis. Here, we report a 5-day-old girl who was conceived after in vitro fertilization with poor suck and facial paralysis. She had bilaterally ptosis and lateral gaze limitation, left-sided deviation of the tongue, dysmorphic face, hypoplastic fingers and finger nails on the left hand, and was diagnosed as having Möbius' syndrome. Involvement of other cranial nerves such as three, four, five, nine, 9 and 12, and limb malformations may accompany this syndrome...

The polarization of light can exhibit unusual features when singular optical beams are involved. In 3-dimensional polarized random media the polarization orientation around singularities describe 1/2 or 3/2 Möbius strips. It has been predicted that if singular beams intersect non-collinearly in free space, the polarization ellipse rotates forming many-turn Möbius strips or twisted ribbons along closed loops around a central singularity. These polarization features are important because polarization is an aspect of light that mediate strong interactions with matter, with potential for new applications...

The appearance of supernumeraries of high-order rainbows in heavy rain showers is explored for rainbows up to order five (p=6). This is done by using a combination of the ray-theory-based first-order Möbius approximation for high-order rainbows with the Airy approximation of the rainbow radiance distribution. We conclude that supernumerary formation of rainbows of order three, four, and five is possible in natural rain showers. Supernumeraries of the third-order and fourth-order rainbows are preferentially formed near the bottom of these rainbows...

Using ray theory, the Möbius shift of the (p-1)-order rainbow angle for a particle having an elliptical cross section is obtained to first order in the ellipticity as a function of the tilt of the ellipse with respect to the propagation direction of the incoming rays. The result is then adapted to the geometry of scattering of light rays from the sun by a falling water drop as a function of sun height angle. The variation in the angular spacing between the supernumeraries is determined as a function of location along the rainbow arc, the conditions under which the rainbow angle is insensitive to drop flattening were determined, and the dependence of the Möbius shift on the drop refractive index is shown for rainbows up to fourth order (p=5)...

An unstable conjugated homoporphyrin was successfully stabilized by introducing meso-aryl substitutents. It was evident from the moderate diatropic ring current found by NMR analysis that the newly formed 20π conjugated free base and its protonated form exhibited Möbius aromatic character. Furthermore, complexation as a ligand with an Rh(I) ion afforded a unique binding mode and retained the Möbius aromaticity. Overall, these compounds are the smallest Möbius aromatic molecules, as confirmed by spectral and crystal-structure analysis and supported by theoretical studies...

We report the synthesis and structural characterization of a heteroleptic mononuclear discrete complex [Cd(N3)2(L)(MeOH)]·MeOH (1·MeOH) and a one-dimensional coordination polymer of the composition [Cd3(N3)6(L)]n (2), fabricated from Cd(NO3)2·4H2O and the helical organic ligand benzilbis((pyridin-2-yl)methylidenehydrazone) (L) in the presence of two equivalents of NaN3. The formation of different structures is driven by the solvent. The former complex is formed in the presence of MeOH, while the latter complex is formed in EtOH...

3,5-Diformyl-4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (3,5-diformyl-BODIPY) can be used as an efficient biofunctional cross-linker to generate a new class of chitosan-based hydrogels with fluorescence resonance energy transfer (FRET) dynamics and good solubility in water. The hydrogel was fully characterized by FT-IR, UV-vis, fluorescence, FE-SEM, AFM, rheology and picosecond time-resolved spectroscopic techniques. The self-healing ability was demonstrated by rheological recovery and macroscopic and microscopic observations...

Using isotope labeled water (D2O and H2(17)O) and pulsed W-band (94 GHz) high-field multiresonance EPR spectroscopies, such as ELDOR-detected NMR and ENDOR, the biologically important question of detection and quantification of local water in proteins is addressed. A bacterial reaction center (bRC) from Rhodobacter sphaeroides R26 embedded into a trehalose glass matrix is used as a model system. The bRC hosts the two native radical cofactor ions (primary electron donor) and (primary electron acceptor) as well as an artificial nitroxide spin label site-specifically attached to the surface of the H-protein domain...

Congenital cranial dysinnervation disorders (CCDDs) comprise a heterogeneous spectrum of diseases characterized by congenital, non-progressive impairment of eye, eyelid and/or facial movements including Möbius syndrome, Duane retraction syndrome, congenital ptosis, and congenital fibrosis of the extraocular muscles. Over the last 20 years, several CCDDs have been identified as neurodevelopmental disorders that are caused by mutations of genes involved in brain and cranial nerve development, e.g. KIF21A and TUBB3 that each plays a pivotal role for microtubule function...

The organocatalyzed photo-atom transfer radical polymerization (photoATRP) using 10-phenylphenothiazine as catalyst is studied toward its use in methacrylic acid (MAA) polymerization and surface grafting. The organocatalyzed photoATRP of methyl methacrylate (MMA) is first optimized for continuous flow synthesis in order to assess the livingness of the polymerization. MMA can be polymerized in batch and in flow; however, conversions are limited by the loss of bromine functionality and hence high conversions have to be traded in with increasing dispersities...

Over the past decade, the hexaphyrin skeleton has emerged as a multifaceted frame exhibiting strong interplay between topology, aromaticity, and metal coordination, opening new research areas beyond porphyrins. However, molecular recognition with hexaphyrins has been underexplored, mainly because of the lack of general synthetic strategies leading to sophisticated molecular hosts. Here we have developed a straightforward approach for capping the heteroannulene frame with tripodal units (e.g., tris(2-aminoethyl)amine [tren]) through postsynthetic modification of a readily accessible meso-(2-aminophenyl) tris-substituted platform...
