Polycystic ovary syndrome (PCOS) is a common endocrine disorder with unclear etiology. Some genes may be pleiotropically or potentially causally associated with PCOS. In the present study, the summary data-based Mendelian randomization (SMR) method integrating genome-wide association study (GWAS) for PCOS and expression quantitative trait loci (eQTL) data was applied to identify genes that were pleiotropically associated with PCOS.

Introduction: Nivolumab plus cabozantinib improved progression-free survival and overall survival compared with sunitinib in the first-line treatment of advanced renal cell carcinoma (RCC) according to CheckMate 9ER study.

Methods: A Markov model was developed to compare the costs and effectiveness of nivolumab plus cabozantinib with those of sunitinib in the first-line treatment of advanced RCC. Primary outcomes were costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER).

We propose an on-chip all-optical multilevel amplitude regenerator scheme over a Mach Zehnder interferometer (MZI) configuration, enabling multiple amplitude-noise suppression on 16-QAM signals. Joint parameter optimization is carried out based on the general nonlinear model of the proposed scheme to significantly reduce the phase distortion caused by the nonlinear interferometer, which is the key to perform the phase preserving operation. The full function of the phase-preserving amplitude regeneration (PPAR) is verified by an experiment on an on-chip nonlinear waveguide with the length of the 2.

Optical fiber facet has rapidly emerged as a powerful light-coupling platform for integrating metasurfaces with miniaturized footprint and multifarious functionalities, through direct lithographic patterning or decal transfer. However, the fiber integrated metasurfaces investigated so far have been usually limited to high refractive index (RI) materials, thus leading to severe impedance mismatch at the fiber/metasurface interface and low efficiency. Here we report a single-mode fiber (SMF) integrated metalens based on low-RI material.

We introduce a simple method with thermal annealing round gold disk for agglomeration to fabricate orderly arranged nanostructure arrays on diamond for single photon source applications. In the annealing process, the dependence of gold sphere size on disk thickness and diameter was investigated, showing that gold sphere diameter was decreased with decreasing gold disk thickness or diameter. The condition parameters of ICP etch were adjusted to obtain different nanostructure morphologies on diamond.

A novel nanosensor based on a metal-insulator-metal waveguide coupled to a double ring resonator is proposed. The spectral characteristics are studied by finite element method, and a Fano resonance (FR) formed by the interference of the narrowband mode and the broadband mode is discovered. After analyzing the effects of structural parameters on the transmission characteristics, the structure is further optimized by adding a rectangular cavity inside the ring cavity.

Purpose: To evaluate focal choroidal excavation (FCE) in eyes with various diseases using multimodal imaging modalities and to investigate the correlation of FCE and underlying chorioretinal diseases.

Methods: This retrospective observational study included 62 eyes from 56 patients who were identified by optical coherence tomography as having FCE. All included patients underwent comprehensive clinical examinations and multimodal imaging to identify and detect the characteristics of FCE and its correlation with underlying chorioretinal diseases.

Pathologic N2 non-small cell lung cancer (NSCLC) is prominently intrinsically heterogeneous. We aimed to identify homogeneous prognostic subgroups and evaluate the role of different adjuvant treatments. We retrospectively collected patients with resected pathologic T1-3N2M0 NSCLC from the Shanghai Chest Hospital as the primary cohort and randomly allocated them (3:1) to the training set and the validation set 1.

Flat irregular pigment epithelial detachment (FIPED) in chronic central serous chorioretinopathy (CSC) is strongly associated with type 1 choroidal neovascularization (CNV). The present study aimed to describe the multimodal imaging characteristics of FIPED in patients with chronic CSC and investigate the factors associated with vascularized FIPED. We included 55 chronic CSC eyes with vascularized FIPED (47 patients) and 55 chronic CSC eyes with avascular FIPED from age-matched patients (47 patients).

Objective: Inflammation plays a crucial role in tumorigenesis and progression. Our purpose was to investigate the prognostic value of neutrophil-to-lymphocyte ratio (NLR), systemic inflammation response index (SIRI) and systemic immune-inflammation index (SII), and develop a nomogram to predict the cancer-specific survival (CSS) and disease-free survival (DFS) of stage I lung adenocarcinoma patients.

Methods: 1431 patients undergoing surgical resection with pathologically confirmed stage I lung adenocarcinoma were reviewed.

With rapid economic growth, urbanization and industrialization, fine particulate matter with aerodynamic diameters ≤ 2.5 µm (PM) has become a major pollutant and shows adverse effects on both human health and the atmospheric environment. Many studies on estimating PM concentrations have been performed using statistical regression models and satellite remote sensing.

Anemia is a common complication of chronic kidney disease (CKD). Recombinant human erythropoietin (rHu-EPO) is used extensively in patients with CKD. However, anti-erythropoietin (anti-EPO) antibody has been reported during rHu-EPO treatment, which causes pure red cell aplasia (PRCA).

Background: To evaluate the application of Arterial Enhancement Fraction (AEF) texture features in predicting the tumor response in Hepatocellular Carcinoma (HCC) treated with Transarterial Chemoembolization (TACE) by means of texture analysis.

Methods: HCC patients treated with TACE in Shengjing Hospital of China Medical University from June 2018 to December 2019 were retrospectively enrolled in this study. Pre-TACE Contrast Enhanced Computed Tomography (CECT) and imaging follow-up within 6 months were both acquired.

Article Synopsis
  • The study aimed to assess the immunogenicity of proteins and identify cross-reactive proteins related to two different pathogens.
  • Mice were immunized with protein extracts, showing significant immune responses, including increased cytokine and immunoglobulin levels, and better control of bacterial loads.
  • Genome analysis identified 396 common genes and 60 cross-reactive antigens between the pathogens, suggesting potential targets for developing new tuberculosis vaccines.

Angiosarcoma of the scalp is an aggressive tumor with a high rate of local recurrence and distant metastasis. We present two cases of metastasis in parotid region at the time of one year after radical surgery of scalp angiosarcoma. It is suggested that regional lymph nodes should be treated more aggressively at the first treatment, which may achieve better results or, at least, prolong the time to local recurrence and distant metastasis.

  • No studies have previously assessed the effectiveness of Adalimumab (ADA) as a first-line treatment for retinal vasculitis in patients with Behçet's Uveitis who have not received prior treatment.
  • A study analyzed the outcomes of 45 treatment-naïve patients with retinal vasculitis, comparing those treated with ADA plus conventional therapy to those receiving conventional therapy alone for at least six months.
  • Results showed that the ADA group had significantly better improvements in retinal vasculitis scores, visual acuity, and inflammation control, with fewer relapses and lower glucocorticoid usage compared to the conventional therapy group.

Bone exhibits piezoelectric properties. Thus, electrical stimulations such as pulsed electromagnetic fields (PEMFs) and stimuli-responsive piezoelectric properties of scaffolds have been investigated separately to evaluate their efficacy in supporting osteogenesis. However, current understanding of cells responding under the combined influence of PEMF and piezoelectric properties in scaffolds is still lacking.

Tumor cell apoptosis evasion is one of the main reasons for easy metastasis occurrence, chemotherapy resistance, and the low five-year survival rate of digestive system tumors. Current research has shown that non-apoptotic cell death plays an important role in tumors of the digestive system. Therefore, increasing the proportion of non-apoptotic tumor cells is one of the effective methods of improving therapeutic efficacies for digestive system tumors.
