Association between pituitary adenoma consistency, resection techniques, and patient outcomes: a single-institution experience.

Objective: The present study aimed to investigate the association between pituitary adenoma (PA) consistency and other measurable tumor characteristics, extent of resection (EOR), postoperative complications, and outcomes.

Methods: In total, 507 PA resections were intraoperatively assigned a consistency grade from 1 (cystic/hemorrhagic tumors) to 5 (calcified tumors) based on intraoperative tumor characteristics. Tumor consistency was analyzed in tertiles (grades 1 and 2, grade 3, and grades 4 and 5) to determine associations with tumor characteristics, EOR, recurrence, postoperative outcomes, and complications.

Supervised Functional Principal Component Analysis Under the Mixture Cure Rate Model: An Application to Alzheimer'S Disease.

Brain imaging data is one of the primary predictors for assessing the risk of Alzheimer's disease (AD). This study aims to extract image-based features associated with the possibly right-censored time-to-event outcomes and to improve predictive performance. While the functional proportional hazards model is well-studied in the literature, these studies often do not consider the existence of patients who have a very low risk and are approximately insusceptible to AD.

Enhancing Photodynamic Therapy Efficacy via Photo-Triggered Calcium Overload and Oxygen Delivery in Tumor Hypoxia Management.

: Photodynamic therapy (PDT) has emerged as a promising treatment for cancer, primarily due to its ability to generate reactive oxygen species (ROS) that directly induce tumor cell death. However, the hypoxic microenvironment commonly found within tumors poses a significant challenge by inhibiting ROS production. This study aims to investigate the effect of improving tumor hypoxia on enhancing PDT.

High-Performance Hydrogen Sensing at Room Temperature via Nb-Doped Titanium Oxide Thin Films Fabricated by Micro-Arc Oxidation.

Metal oxide semiconductor (MOS) hydrogen sensors offer advantages, such as high sensitivity and fast response, but their challenges remain in achieving low-cost fabrication and stable operation at room temperature. This study investigates Nb-doped TiO (NTO) thin films prepared via a one-step micro-arc oxidation (MAO) with the addition of NbO nanoparticles into the electrolyte for room-temperature hydrogen sensing. The characterization results revealed that the incorporation of NbO altered the film's morphology and phase composition, increasing the Nb content and forming a homogeneous composite thin film.

The smoky scent is the most distinctive feature for Souchong black tea. To reduce the dependence on pinewood in the smoking process of Souchong black tea, it is crucial to find an effective alternative smoking material. Five black tea samples were prepared via using specially designed fuel rods as the smoking material in this study.

MSC-sEVs exacerbate senescence by transferring bisecting GlcNAcylated GPNMB.

Background: The senescence of bone marrow mesenchymal stem cells (BMMSCs) is increasingly recognized as a critical factor contributing to the pathophysiology of age-related diseases. Recent studies suggest that small extracellular vesicles (sEVs) derived from the serum of elderly individuals may play a pivotal role in promoting BMMSC senescence. Glycoprotein non-metastatic melanoma protein B (GPNMB), a type I transmembrane glycoprotein, is upregulated during cellular senescence and can regulate stem cell ageing.

Microneedle patch-involved local therapy synergized with immune checkpoint inhibitor for pre- and post-operative cancer treatment.

The metastasis and recurrence of cancer post-surgery remain the major reasons for treatment failures. Herein, a photo-immune nanoparticle decorating with M1 macrophage membrane (BD@LM) is designed based on the inflammatory environment after surgical resection. By loading photosensitizer black phosphorus quantum dots (BPQDs) and chemotherapeutics doxorubicin (DOX) in BD@LM nanoparticles, an effective chemophototherapy-mediated immunogenic cell death of tumor cells is triggered, subsequently leading to the maturation of dendritic cells for further immune cascade.

Comparative analysis of small-incision and traditional techniques in costal cartilage harvesting: Outcomes on thoracic deformities and scar appearance.

Objective: This study aims to compare the postoperative thoracic deformity and scar aesthetic outcomes of auricular reconstruction between the conventional large-incision technique and small-incision technique with perichondrium preservation for costal cartilage harvesting.

Methods: A retrospective analysis was performed on 134 patients who underwent auricular reconstruction using tissue expanders and autologous costal cartilage harvested from the right chest wall between January 2021 and September 2023. Patients were divided into two groups according to the harvesting technique: the traditional large-incision group (n = 64) and the small-incision group with perichondrium preservation (n = 70).

Polarimetric Compressed Sensing with Hollow, Self-Assembled Diffractive Films.

Sensing light's polarization and wavefront direction enables surface curvature assessment, material identification, shadow differentiation, and improved image quality in turbid environments. Traditional polarization cameras utilize multiple sensor measurements per pixel and polarization-filtering optics, which result in reduced image resolution. We propose a nanophotonic pipeline that enables compressive sensing and reduces the sampling requirements with a low-refractive-index, self-assembled optical encoder.

Advances in Research on Marine Natural Products for Modulating the Inflammatory Microenvironment.

In recent years, marine natural products (MNPs) have emerged as crucial sources of lead compounds for the advancement of anti-inflammatory drugs due to their abundant diversity, complexity, and distinctiveness. Inflammatory microenvironments (IMEs) are pervasive pathological features in the etiology of various chronic diseases, referring to the localized milieu or ecosystem where inflammatory responses occur, and they play a pivotal role in the onset and progression of inflammatory diseases. Uncontrolled IMEs can lead to dysregulation of inflammatory mediators within signaling pathways, thereby exerting detrimental effects on human health and even contributing to the development of inflammatory diseases such as cancer.

Prevalence of malnutrition among adult inpatients in China: a nationwide cross-sectional study.

Malnutrition substantially contributes to adverse clinical outcomes. However, no national survey has been conducted to characterize its epidemiology in hospital settings in China. We conducted the China Nutrition Fundamental Data 2020 project among a multistage stratified cluster sample of adult inpatients from 291 study sites across 30 provinces, autonomous regions and municipalities (except for Hong Kong, Macao, Taiwan Province, and the Xizang Autonomous Region, please see MATERIALS AND METHODS for details of the causes) of China to generate reliable data on the prevalence of malnutrition and explore the associated risk factors.

Neuroimaging stratification reveals the striatal vulnerability to stress as a risk for schizophrenia.

The striatum, a core brain structure relevant for schizophrenia, exhibits heterogeneous volumetric changes in this illness. Due to this heterogeneity, its role in the risk of developing schizophrenia following exposure to environmental stress remains poorly understood. Using the putamen (a subnucleus of the striatum) as an indicator for convergent genetic risk of schizophrenia, 63 unaffected first-degree relatives of patients (22.

Methods: We conducted the first exome-wide association analysis on loneliness and social isolation, utilizing 336,115 participants of white-British ancestry for loneliness and 346,115 for social isolation.

TiN Boosting the Oxygen Reduction Performance of Fe-N-C through the Relay-Catalyzing Mechanism for Metal-Air Batteries.

Metal-air batteries desire highly active, durable, and low-cost oxygen reduction catalysts to replace expensive platinum (Pt). The Fe-N-C catalyst is recognized as the most promising candidate for Pt; however, its durability is hindered by carbon corrosion, while activity is restricted due to limited oxygen for the reaction. Herein, TiN is creatively designed to be hybridized with Fe-N-C (TiN/Fe-N-C) to relieve carbon corrosion and absorb more oxygen when catalyzing oxygen reduction.
