PURPOSE: We aimed at investigating the incidence and risk factors of non-IgE-mediated gastrointestinal food allergies (non-IgE-GI-FAs) in neonates and infants. METHODS: A total of 126 infants who underwent neonatal gastrointestinal surgeries were grouped into those with (n = 13) and those without an onset of non-IgE-GI-FAs (n = 113). The characteristics of the two groups (e.g., birth weight, delivery type, small intestinal surgeries, and pre-/postoperative nutrition) were compared...

Potassium represents one of the most crucial minerals in infant formula that supports healthy growth and development of infants. Here, a novel strategy for the real-time quantification of potassium in infant formula samples is introduced. Using laser-induced breakdown spectroscopy (LIBS) in a data-driven approach, a modified random frog algorithm (MRFA) is adopted in a higher-density discrete wavelet transform (HDWT) domain for the selection of the most important features related to potassium, which is named as DD-LIBS...

A novel metrics termed the 'wave electromechanical coupling factor' (WEMCF) is proposed in this paper, to quantify the coupling strength between the mechanical and electric fields during the passage of a wave in piezoelectric composites. Two definitions of WEMCF are proposed, leading to a frequency formula and two energy formulas for the calculation of such a factor. The frequency formula is naturally consistent with the conventional modal electromechanical coupling factor (MEMCF) but the implementation is difficult...

BACKGROUND: Prevention of relapse is a major issue in the management of quiescent Crohn's disease (CD). Current therapies (e.g. methotrexate, biologics, 6-mercaptopurine and azathioprine) may be effective for maintaining remission in CD, but these drugs may cause significant adverse events. Interventions that are effective and safe for maintenance of remission in CD are desirable. OBJECTIVES: The primary objectives were to evaluate the efficacy and safety of enteral nutrition for the maintenance of remission in CD and to assess the impact of formula composition on effectiveness...

Parton quasidistribution functions provide a path toward an ab initio calculation of parton distribution functions (PDFs) using lattice QCD. One of the problems faced in calculations of quasi-PDFs is the renormalization of a nonlocal operator. By introducing an auxiliary field, we can replace the nonlocal operator with a pair of local operators in an extended theory. On the lattice, this is closely related to the static quark theory. In this approach, we show how to understand the pattern of mixing that is allowed by chiral symmetry breaking and obtain a master formula for renormalizing the nonlocal operator that depends on three parameters...

OBJECTIVES: No formal comparative effectiveness studies have been conducted to evaluate the effect of eosinophilic esophagitis (EoE) treatment choice on long-term growth in pediatric patients. However, long-term studies of inhaled corticoid steroids in asthma suggest possible effects on linear growth. The aim of this study was to compare longitudinal, anthropometric growth in children with EoE according to treatment approach. METHODS: We conducted a retrospective, multicenter cohort study of anthropometric growth (height and BMI z-scores) in pediatric (<18 years of age) patients newly diagnosed with EoE across 5 clinical sites between 2005-2014...

Quantitative magnetic resonance imaging (MRI) provides useful information about intervertebral disc (IVD) biomechanical properties, especially those in relation to the fluid phase. These properties may improve IVD finite element (FE) models using data closer to physiological reality. The aim of this study is to investigate IVD degeneration-related properties using a coupling between MRI and FE modeling. To this end, proton density ([Formula: see text])-weighted MRI sequences of a porcine lumbar IVD were carried out to develop two biphasic swelling models with hyperelastic extracellular matrix behavior...

We introduce, to the best of our knowledge, a new class of twisted partially coherent sources for producing rotating Gaussian array profiles. The general analytical formula for the cross-spectral density function of a beam generated by such a novel source propagating in free space is derived, and its propagation characteristics are analyzed. It is shown that both the irradiance profile of each element of the array and the degree of coherence rotate during propagation, but in opposite directions. Further, the twist effects of the spectral density and the degree of coherence are quantified...

Raman scattering measurements of monolayer WS2 are reported as a function of the laser excitation energies from the near-infrared (1.58 eV) to the deep-ultraviolet (4.82 eV). In particular, we observed several strong Raman peaks in the range of 700∼850 cm-1 with the deep-ultraviolet laser lights (4.66 eV and 4.82 eV). Using the first-principles calculations, these peaks and other weak peaks were appropriately assigned by the double resonance Raman scattering spectra of phonons around the M and K points in the hexagonal Brillouin zone...

We study the existence of travelling breathers and solitary waves in the discrete p -Schrödinger (DpS) equation. This model consists of a one-dimensional discrete nonlinear Schrödinger (NLS) equation with strongly nonlinear inter-site coupling (a discrete p -Laplacian). The DpS equation describes the slow modulation in time of small amplitude oscillations in different types of nonlinear lattices, where linear oscillators are coupled to nearest-neighbours by strong nonlinearities. Such systems include granular chains made of discrete elements interacting through a Hertzian potential ( p  = 5/2 for contacting spheres), with additional local potentials or resonators inducing local oscillations...

Raw coal fly ash (RCFA) was used directly as adsorbent to treat coking wastewater. The results show that the RCFA can introduce COD (14, 4, and 11 mg L-1 at pH = 1.0, 7.0, and 14.0, respectively) into water due to the dissolution of reductive components from RCFA, this can be avoided by washing (6 times) using distilled water. The concentration of leached metal elements in wastewater is lower than the standard in GB18918-2002, China. The adsorption process accords with the pseudo-second order adsorption kinetic model and Langmuir thermodynamics model better than other ones, and it belongs to a physical and exothermic process...

AIMS: The Glaucoma Stereo Analysis Study (GSAS) is a multicentre collaborative study of the characteristics of glaucomatous optic disc morphology using a stereo fundus camera. Using the GSAS dataset, we previously established a formula for predicting different appearances of glaucomatous optic discs, although the formula lacked validation in an independent dataset. In this study, the formula was validated in another testing dataset. SUBJECTS AND METHODS: Testing dataset contained three-dimensionally analysed optic disc topographic parameters from 93 eyes with primary open-angle glaucoma; six topographic parameters (temporal and nasal rim-disc ratios, mean cup depth, height variation contour, disc tilt angle and rim decentring absolute value) were used for predicting different appearances of glaucomatous optic discs...

The Ni-metallated porphyrin-based tetraphosphonic acid (Ni-tetra(4-phosphonophenyl)porphyrin, Ni-H8 TPPP) was used for the synthesis of highly porous metal phosphonates containing the tetravalent cations Zr4+ and Hf4+ . The compounds were thoroughly characterized regarding their sorption properties towards N2 and H2 O as well as thermal and chemical stability. During the synthesis optimization the reaction time could be substantially decreased under stirring from 24 to 3 h in glass vials. M-CAU-30, [M2 (Ni-H2 TPPP)(OH/F)2 ]·H2 O (M = Zr, Hf) shows exceptionally high specific surface areas for metal phosphonates of a BET = 1070 and 1030 m2 g-1 for Zr- and Hf-CAU-30, respectively, which are very close/correspond to the theoretical values of 1180 and 1030 m2 g-1 ...
