PURPOSE: To assess the correlation between corneal biomechanical stiffness and refractive error (RE) in the pediatric population. METHODS: A total of 733 pediatric eyes were included in the study retrospectively. All eyes underwent corneal tomography (Pentacam), RE assessment, and air-puff deformation (Corvis-ST). Waveform analyses of deformation provided corneal stiffness (CS) and extraocular tissue stiffness (EOS). Eyes were subgrouped into emmetropia [manifest refraction spherical equivalent (MRSE) ∼ 0 D], hyperopia (MRSE > 0 D), myopia I (MRSE between 0 D and -3 D), myopia II (MRSE between -3 D and -6 D), and myopia III (MRSE greater than -6 D) for multivariate analyses...

BACKGROUND: Perilla EO possess high antioxidant, antimicrobial and insecticidal activities, and have proven to be more reliable than chemically synthesized food preservatives. Nevertheless, EOs have disadvantages of facile photo-degradation and oxidation which limits their use in agriculture and food industries. Microencapsulation technology that generates a polymeric coating surrounding EOs could overcome these disadvantages. RESUILS: The EO concentration had a significant effect on encapsulation efficiency (EE) and loading capacity (LC)...

During this work, we demonstrate, for the first time, that the volumetric properties of pure ionic liquids could be truly predicted as a function of temperature from 219 K to 473 K and pressure up to 300 MPa. This has been achieved by using only density and isothermal compressibility data at atmospheric pressure through the Fluctuation Theory-based Tait-like Equation of State (FT-EoS). The experimental density data of 80 different ionic liquids, described in the literature by several research groups as a function of temperature and pressure, was then used to provide comparisons...

Beryllium has been considered a superior ablator material for inertial confinement fusion (ICF) target designs. An accurate equation-of-state (EOS) of beryllium under extreme conditions is essential for reliable ICF designs. Based on density-functional theory (DFT) calculations, we have established a wide-range beryllium EOS table of density ρ = 0.001 to 500 g/cm(3) and temperature T = 2000 to 10(8) K. Our first-principle equation-of-state (FPEOS) table is in better agreement with the widely used SESAME EOS table (SESAME 2023) than the average-atom INFERNO and Purgatorio models...

BACKGROUND CONTEXT: Global balance of human standing is analyzed as the geometric sum of the individual alignments extending from the spinal column to the pelvis, and to the lower limbs. The innovative EOS system has opened new perspectives for the global analysis of whole body alignment, but its use is very limited due to its high cost. An alternative may be to combine the whole spine lateral radiograph and the lateral scanogram in the global sagittal analysis of whole body alignment...

BACKGROUND: The genesis of schizophrenia is multifactorial, including biological and environmental risk factors. We tested for an interactive effect between early-onset schizophrenia (EOS) and social class of origins (socioeconomic status (SES)). Data were further analyzed for a possible connection to type of schizophrenic symptoms. Sampling/Methods: Data for the study are taken from the medical records of 642 patients from a large state hospital in the northeastern United States. Clinical assessments were divided into positive and negative symptomatology through application of the Scale for the Assessment of Negative Symptoms (SANS), the Scale for the Assessment of Positive Symptoms (SAPS) and the Positive and Negative Syndrome Scale (PANSS)...

BACKGROUND: Although most hip dislocations occur in either standing or sitting position, the safe zone for implant position is defined for the supine position. Our goal was to determine preoperative and postoperative pelvis and hip orientations and whether the safe zone defined in supine position can be used to assess standing radiographs. METHODS: Preoperative and postoperative three-dimensional EOS images were assessed in 66 total hip arthroplasty patients. None of the patients had dislocation within the follow-up period (12-36 months)...

In patients with COPD, there is controversy regarding the association of blood eosinophil (Eos) levels with 1) exacerbation frequency and 2) the effect of inhaled corticosteroids for prevention of exacerbations. To determine whether Eos define subgroups of patients exhibiting attributes of COPD clinical phenotypes, we compared clinical features and mortality rates in COPD patients from the Initiatives BPCO French cohort categorized using different thresholds of blood Eos levels. The following data were collected at inclusion: medical and smoking history, occupational exposures, dyspnea, cough and sputum production, exacerbations in the previous year, history of allergy and asthma, nasal symptoms, body mass index, St George Respiratory Questionnaire (SGRQ) total score, post-bronchodilator spirometry, comorbidities, and medications...

The use of intracellular reductive microenvironment to control the release of therapeutic payloads has emerged as a popular approach to design and fabricate intelligent nanocarriers. However, these reduction-responsive nanocarriers are generally trapped within endolysosomes after internalization and are subjected to unwanted disintegration, remarkably compromising the therapeutic performance. Herein, amphiphilic polyprodrugs of poly(N,N-dimethylacrylamide-co-EoS)-b-PCPTM were synthesized via sequential reversible addition-fragmentation chain transfer (RAFT) polymerization, where EoS and CPTM are Eosin Y- and camptothecin (CPT)-based monomers, respectively...
