Tumor neoantigens as key drivers of significant anti - tumor immunity in triple - negative breast cancer mouse models.

Recent studies have highlighted the therapeutic potential of targeting tumor neoantigens in solid tumors; however, its efficacy in breast cancer remains unclear. Here, we evaluate the impact of tumor neoantigen-targeted strategies in a syngeneic mouse mammary carcinoma model. Mice previously exposed to 4T1 tumor cells (PETCs) or treated with tumor cell-derived lysates (TdLs) exhibited robust antitumor immunity, leading to reduced tumor growth and metastasis through tumor immune microenvironment remodeling.

Singular states of resonant nanophotonic lattices.

Fundamental effects in nanophotonic resonance systems focused on singular states and their properties are presented. Strongly related to lattice geometry and material composition, there appear resonant bright channels and non-resonant dark channels in the spectra. The bright state corresponds to high reflectivity guided-mode resonance (GMR) whereas the dark channel represents a bound state in the continuum (BIC).

Recent Increases in Influenza-Related Hospitalizations, Critical Care Resource Use, and In-Hospital Mortality: A 10-Year Population-Based Study in South Korea.

Background: Long-term trends in influenza-related hospitalizations, critical care resource use, and hospital outcomes since the 2009 H1N1 influenza pandemic season have been rarely studied for adult populations. Materials and Methods: Adult patients from the Korean Health Insurance Review and Assessment Service who were hospitalized with influenza over a 10-year period (2009−2019) were analyzed. The incidence rates of hospitalization, critical care resource use, and in-hospital death were calculated using mid-year population census data.

JAK2 regulates paclitaxel resistance in triple negative breast cancers.

We investigated the molecular mechanisms of paclitaxel resistance in TNBC using seven patient-derived xenograft (PDX) models and TNBC cell lines. Among the seven PDX models, four models showed resistance to paclitaxel. Dysregulation of JAK/STAT pathways and JAK2 copy number gains were observed in the four paclitaxel-resistant PDX tumors.

Therapeutic Prognosis System for Root Coverage Procedures.

Although several techniques and materials have been adopted to treat gingival recession, the therapeutic prognosis of various treatment modalities is not well established. This article proposes a multidimensional therapeutic prognosis system for the treatment of gingival recession based on the currently available literature. Gingival defect characteristics, patient behavioral habits, and surgical- and anatomical-related factors that may affect the outcome of root coverage procedures are reviewed.

Brain natriuretic peptide levels predict 6-month mortality in patients with cardiogenic shock who were weaned off extracorporeal membrane oxygenation.

There are limited data regarding the association between brain natriuretic peptide (BNP) levels obtained after weaning from extracorporeal membrane oxygenation (ECMO) and the outcomes of patients with acute coronary syndrome (ACS)-associated cardiogenic shock.We prospectively obtained data regarding patients (aged ≥ 19 years) with ACS-associated cardiogenic shock who received ECMO and were subsequently weaned off the treatment. BNP levels were collected at 5 time points: pre-ECMO implantation, post-ECMO implantation, pre-ECMO weaning, day 1 after ECMO weaning, and day 5 after ECMO weaning.

Rapid large-scale fabrication of multipart unit cell metasurfaces.

Periodic diffractive elements known as metasurfaces constitute platform technology whereby exceptional optical properties, not attainable by conventional means, are attained. Generally, with increasing unit-cell complexity, there emerges a wider design space and bolstered functional capability. Advanced devices deploying elaborate unit cells are typically generated by electron-beam patterning which is a tedious, slow process not suitable for large surfaces and quick turnaround.

Development of a pressure sensor system for unobtrusive monitoring of abdominal muscle activities.

Surface electromyogram (sEMG) is often used by to objectively measure muscular activity during rehabilitation exercises. sEMG is accurate, but it is unsuitable for uses outside the clinic, and patients can benefit from an unobtrusive device which can be readily used to ubiquitously measure abdominal muscle activation. In this study, we present a pressure sensor system which can be latched onto a belt to measure abdominal muscle activation.

Flat-top narrowband filters enabled by guided-mode resonance in two-level waveguides.

Resonant nanogratings and periodic metasurfaces express diverse spectral and polarization properties on broadside illumination by incident light. Cooperative resonance interactions may yield shaped spectra for particular applications, in contrast to a multilayer dielectric mirror. Here, we provide guided-mode resonance filters with flat-top spectra suitable for wavelength division multiplexing systems.

Kalopanacis Cortex extract-capped gold nanoparticles activate NRF2 signaling and ameliorate damage in human neuronal SH-SY5Y cells exposed to oxygen-glucose deprivation and reoxygenation.

Recently, environment-friendly synthesis of gold nanoparticles (GNPs) has been extensively explored by biologists and chemists. However, significant research is still required to determine whether "eco-friendly" GNPs are beneficial to human health and to elucidate the molecular mechanisms of their effects on human cells. We used human neuronal SH-SY5Y cells to show that treatment with Kalopanacis Cortex extract-capped GNPs (KC-GNs), prepared via an eco-friendly, fast, one-pot synthetic route, protected neuronal cells against oxygen-glucose deprivation/reoxygenation (OGD/R)-induced damage.

We demonstrate unpolarized wideband reflectors fashioned with orthogonal serial resonant reflectors. Unpolarized incident light generates internal TM- and TE-polarized reflections that are made to cooperate to extend the bandwidth of the composite spectral reflectance. The experimental results presented show ~42% band extension by a two-grating module.

Here, we developed a simple, fast, efficient, and ecofriendly approach to the synthesis of gold nanoparticles by means of a Gardenia jasminoides extract.

High-Pressure Balloon-Assisted Stretching of the Coracohumeral Ligament to Determine the Optimal Stretching Positions: A Cadaveric Study.

Background: The coracohumeral ligament (CHL) is a thick capsular structure and markedly thickened when affected by adhesive capsulitis. Therapeutic stretching is the most commonly applied treatment for adhesive capsulitis, but optimal stretching postures for maximal therapeutic effects on the CHL have not been fully investigated.

Objective: To investigate the most effective stretching direction for the CHL by measuring the stretching intensity in 5 different directions and to determine whether the stretching intervention resulted in loosening of the ligament by comparing the changes of CHL tightness before and after stretching.

Prediction of nonresponsiveness to medium-dose intravenous immunoglobulin (1 g/kg) treatment: an effective and safe schedule of acute treatment for Kawasaki disease.

Purpose: Medium-dose (1 g/kg) intravenous immunoglobulin (IVIG) is effective in the majority of patients with Kawasaki disease (KD) but some patients who do not respond to medium-dose IVIG are at high risk for the development of coronary artery lesions (CALs). The purpose of this study was to identify the clinical predictors associated with unresponsiveness to medium-dose IVIG and the development of CALs.

Methods: A retrospective study was performed in 91 children with KD who were treated with medium-dose IVIG at our institution from January 2004 to December 2013.

Usefulness of anterior uveitis as an additional tool for diagnosing incomplete Kawasaki disease.

Purpose: There are no specific tests for diagnosing Kawasaki disease (KD). Additional diagnostic criteria are needed to prevent the delayed diagnosis of incomplete Kawasaki disease (IKD). This study compared the frequency of coronary artery lesions (CALs) in IKD patients with and without anterior uveitis (AU) and elucidated whether the finding of AU supported the diagnosis of IKD.

Robust snapshot interferometric spectropolarimetry.

This Letter describes a Stokes vector measurement method based on a snapshot interferometric common-path spectropolarimeter. The proposed scheme, which employs an interferometric polarization-modulation module, can extract the spectral polarimetric parameters Ψ(k) and Δ(k) of a transmissive anisotropic object by which an accurate Stokes vector can be calculated in the spectral domain. It is inherently strongly robust to the object 3D pose variation, since it is designed distinctly so that the measured object can be placed outside of the interferometric module.

Gold-conjugated resveratrol nanoparticles attenuate the invasion and MMP-9 and COX-2 expression in breast cancer cells.

Gold nanoparticles (AuNPs) with antitumorigenic effects obstruct the initiation, development and progression of tumors via the regulation of various processes, such as proliferation and apoptosis. However, the effects of AuNPs on breast cancer metastasis have not been well studied, and their response to 12-O-tetradecanoylphorbol-13-acetate (TPA) stimulation remains unclear. Therefore, we synthesized resveratrol-capped gold nanoparticles (Rev-AuNPs) using green nanotechnology and investigated their potential anti-invasive properties in human breast cancer cells in response to TPA stimulation.

Properties of wideband resonant reflectors under fully conical light incidence.

Applying numerical modeling coupled with experiments, we investigate the properties of wideband resonant reflectors under fully conical light incidence. We show that the wave vectors pertinent to resonant first-order diffraction under fully conical mounting vary less with incident angle than those associated with reflectors in classical mounting. Therefore, as the evanescent diffracted waves drive the leaky modes responsible for the resonance effects, fully-conical mounting imbues reflectors with larger angular tolerance than their classical counterparts.

Ultra-sparse dielectric nanowire grids as wideband reflectors and polarizers.

Engaging both theory and experiment, we investigate resonant photonic lattices in which the duty cycle tends to zero. Corresponding dielectric nanowire grids are mostly empty space if operated as membranes in vacuum or air. These grids are shown to be effective wideband reflectors with impressive polarizing properties.

Relationships Between Capsular Stiffness and Clinical Features in Adhesive Capsulitis of the Shoulder.

Background: Tightening and contracture of the joint capsule are hallmarks of adhesive capsulitis of the shoulder (ACS). However, quantification of capsular stiffness and its relation to clinical features have not been investigated thoroughly.

Objectives: To quantify capsular stiffness during intra-articular hydraulic distension (IHD) and to investigate its relationships with pain severity, symptom duration, range of motion (ROM), gender, and diabetes status.

Efficient band-pass color filters enabled by resonant modes and plasmons near the Rayleigh anomaly.

We design and fabricate efficient, narrow-band, transmission color filters whose operating principle resides in a narrow-band guided-mode resonance associated with a surface-plasmon resonance. The fundamental device consists of an aluminum grating over a 200-nm-thick aluminum oxide film on a glass substrate. Numerical simulations show a sharp resonance-derived spectral profile that is additionally shaped by a neighboring Rayleigh anomaly.

Biomechanical properties of the glenohumeral joint capsule in hemiplegic shoulder pain.

Background: Although many hemiplegic shoulder patients have been suffering from limited range of motion, it is not fully established whether the pathologic biomechanics are same in hemiplegic shoulder pain and adhesive capsulitis. Therefore we aimed to investigate biomechanical properties of glenohumeral joint capsules of hemiplegic shoulder pain with limited range of motions.

Methods: Participants were 14 patients with hemiplegic shoulder pain, 10 controls, and 42 adhesive capsulitis patients matched with the hemiplegic shoulder pain group for sex, age, and range of motion.
