INTRODUCTION: Congenital diaphragmatic disease is a quite common condition that usually occurs in the neonatal period, and the diagnosis of congenital diaphragmatic disease in adulthood is rare. CASE PRESENTATION: A 64-years-old Caucasian woman was admitted in emergency at our Department, due to a bowel obstruction and dyspnea. A CT-scan showed a diaphragmatic herniation in the left area, with malposition of dilated transverse and descending colon in the chest. An emergency laparatomy was performed, showing a toxic megacolon, in the absence of a true diaphragmatic hernia, and a left diaphragm and left liver hypoplasia...

BACKGROUND: Many skin-mounted three-dimensional multi-segmented foot models are currently in use for gait analysis. Evidence regarding the repeatability of models, including between trial and between assessors, is mixed, and there are no between model comparisons of kinematic results. RESEARCH QUESTION: This study explores differences in kinematics and repeatability between five three-dimensional multi-segmented foot models. The five models include duPont, Heidelberg, Oxford Child, Leardini, and Utah...

The passively Q-switched, self-pulsing all-solid-state laser is a device of widespread use in many applications. Depending on the condition of saturation of the absorber, which is easy to adjust, different dynamical regimes are observed: continuous-wave emission, stable oscillations, period doubling bifurcations, chaos, and, within some chaotic regimes, extreme events (EEs) in the form of pulses of extraordinary intensity. These pulses are sometimes called "dissipative optical rogue waves." The mechanism of their formation in this laser is unknown...

Mutagenesis in combination with Genotyping by Sequencing (GBS) is a powerful tool for introducing variation, studying gene function and identifying causal mutations underlying phenotypes of interest in crop plant genomes. About 400 million paired-end reads were obtained from 82 ethylmethane sulfonate (EMS) induced mutants and 14 wild-type accessions of Jatropha curcas for the detection of Single Nucleotide Polymorphisms (SNPs) and Insertion/Deletions (InDels) by two different approaches (nGBS and ddGBS) on an Illumina HiSeq 2000 sequencer...

BACKGROUND: Several multi-segment foot models (MFMs) have been introduced for in vivo analyses of dynamic foot kinematics. However, the normal gait patterns of healthy children and adolescents remain uncharacterized. We sought to determine normal foot kinematics according to age in clinically normal female children and adolescents using a Foot 3D model. METHODS: Fifty-eight girls (age 7-17 years) with normal function and without radiographic abnormalities were tested...

Checkpoint inhibitor medications have revolutionized oncology practice, but frequently induce immune-related adverse events. During autoimmune neurology practice over 20 months, we prospectively identified four patients with likely antibody-mediated neurological diseases after checkpoint inhibitors: longitudinally extensive transverse myelitis, Guillain-Barré syndrome, and myasthenia gravis. All patients shared three characteristics: symptoms commenced 4 weeks after drug administration, responses to conventional immunotherapies were excellent, and autoantibodies traditionally associated with their syndrome were absent...

We explore phase transitions of polariton wave packets, first, to a soliton and then to a standing wave polariton condensate in a multimode microwire system, mediated by nonlinear polariton interactions. At low excitation density, we observe ballistic propagation of the multimode polariton wave packets arising from the interference between different transverse modes. With increasing excitation density, the wave packets transform into single-mode bright solitons due to effects of both intermodal and intramodal polariton-polariton scattering...

PURPOSE: After radiopharmaceutical injection, a heightened 123 I-MIBG concentration is frequently observed in the left hepatic lobe compared to the right one, but the reason of this finding remains unknown. Our aim was to retrospectively analyze the different 123 I-MIBG uptake pattern between the two hepatic lobes and correlate our results with some epidemiological/clinical features. MATERIAL AND METHODS: Ninety-four 123 I-MIBG scintigraphies from 71 patients were selected...

Potassium (K), phosphorous (P), and carboxyfluorescein (CF) accumulate in functionally distinct tissues within the pine seedling root cortex. Seedlings of Pinus pinea translocate exogenous CF and endogenous K and P from the female gametophyte/cotyledons to the growing radicle. Following unloading in the root tip, these materials accumulate in characteristic spatial patterns. Transverse sections of root tips show high levels of P in a circular ring of several layers of inner cortical cells. K and CF are minimal in the high P tissue...

The enhanced incidence of colorectal cancer (CRC) in the U.S.A. has been linked to promutagens, such as heterocyclic aromatic amines, in the western diet that are produced by high temperature cooking of meat. However, a prior analysis of driver nonsense mutations in the Adenomatous Polyposis Coli (APC) gene, which is mutated in 75% of human CRC, indicated that the C·G → A·T transversions produced by this class of mutagens were not enriched but actually lower than what would be statistically anticipated...

REVIEW
Jaclyn Beckinghausen, Roy V Sillitoe
The cerebellum has a well-established role in controlling motor functions such coordination, balance, posture, and skilled learning. There is mounting evidence that it might also play a critical role in non-motor functions such as cognition and emotion. It is therefore not surprising that cerebellar deficits are associated with a wide array of diseases including ataxia, dystonia tremor, schizophrenia, dyslexia, and autism spectrum disorder. What is intriguing is that a seemingly uniform circuit that is often described as being "simple" should carry out all of these behaviors...

We study the collapsible behaviour of a vessel conveying viscous flows subject to external pressure, a scenario that could occur in many physiological applications. The vessel is modelled as a three-dimensional cylindrical tube of nonlinear hyperelastic material. To solve the fully coupled fluid-structure interaction, we have developed a novel approach based on the Arbitrary Lagrangian-Eulerian (ALE) method and the frontal solver. The method of rotating spines is used to enable an automatic mesh adaptation...

We theoretically investigate the far-field scattering properties of multiphoton super- and subradiant states which can be prepared by multiphoton excitations with orbital angular momentum (OAM). Due to multiphoton interference, the far-field patterns of the subradiant modes show directional scattering along the excitation direction or transverse scattering with number of peaks equal to the number of atoms. When more atoms are involved, we consider structures of stacked and concentric rings, which respectively show enhanced directional scattering and smoothed emission patterns...

OBJECTIVE: This study aimed to evaluate the fracture load and pattern of customized and non-customized zirconia abutments with Morse-taper connection. METHODS: 18 implants were divided into 3 groups according to the abutments used: Zr - with non-customized zirconia abutments; Zrc - with customized zirconia abutments; and Ti - with titanium abutments. To test their load capacity, a universal test machine with a 500-kgf load cell and a 0.5-mm/min speed were used. After, one implant-abutment assembly from each group was analyzed by Scanning Electron Microscopy (SEM)...

Electromagnetic fields at near-field exhibit distinctive properties with respect to their free-space counterparts. In particular, an optical transverse spin appearing in a confined electromagnetic field provides the foundation for many intriguing physical effects and applications. We present a transverse spin coupling configuration where plasmonic nanoparticles are employed to couple the transverse spin in a focused beam to that of a surface plasmon polariton. The plasmonic resonance of nanoparticles on a metal film plays a significant role in transverse spin coupling...

Background: Idiopathic intracranial hypertension (IIH) is primarily a disorder of young obese women of unknown etiology. The clinical presentation of IIH is similar to that of sinus thrombosis. The incidence of transverse sinus stenosis (TSS) reaches up to 90% of patients with IIH compared with normal subjects, and venous sinus thrombosis was reported in 11.4% of patients previously diagnosed as having IIH. Patients with thrombosis showed an abnormal region of double- track pattern on gadolinium (Gd) - enhanced T1WI within the dural sinus...

PURPOSE: Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine which exhibits morphological changes during growth. The goal of this study was to identify morphological patterns that could be explained by different loading patterns for AIS. METHODS: Computed tomography data of 21 patients with diagnosed AIS and 48 patients without any visual spinal abnormalities were collected prospectively. The bony structures were reconstructed, and landmarks were placed on characteristic morphological points on the spine...

The first spine of the first dorsal fin (FS) of the Atlantic bluefin tuna (ABFT), Thunnus thynnus, is customarily used in age determination research because its transverse sections display well-defined growth marks. In this paper the FS structure was studied to explain its known dramatic age- and season-related morphological modifications, which are evidently caused by bone remodeling. Cross sections of samples from six adult ABFT were in part decalcified to be stained with histological, histochemical and immunohistochemical methods, and in part embedded in methyl-methacrylate to be either observed under a linear polarized light or microradiographed...

A transverse Bragg resonance (TBR) waveguide semiconductor laser with sampled grating is proposed and analyzed. The transverse phase shift in the middle of the grating is realized by shifting half of the sampling period, resulting in a good single transverse mode resonance. The characteristics such as the modal gain, the electric field distribution, the near and far field beam patterns are theoretically studied. Since the sampled grating is designed by combining a uniform basic grating with a micrometer scale sampling pattern, it can be easily fabricated by holographic exposure and conventional photolithography with low cost...
