Background: Existing biomarkers and models for predicting response to programmed cell death protein 1 monoclonal antibody in advanced squamous-cell non-small cell lung cancer (sqNSCLC) did not have enough accuracy. We used data from the ORIENT-3 study to construct artificial neural network (ANN) systems to predict the response to sintilimab for sqNSCLC.

Methods: Four ANN systems based on bulk RNA data to predict disease control (DC), immune DC (iDC), objective response (OR) and immune OR (iOR) were constructed and tested for patients with sqNSCLC treated with sintilimab.

Background: Cancer, particularly tumors of the digestive system, presents a major global health challenge. The incidence and mortality rates of these cancers are increasing, and many patients face significant nutritional risks, which are often overlooked in clinical practice. This oversight can lead to serious health consequences, underscoring the need for effective nutritional assessment tools to improve clinical outcomes.

Nasopharyngeal carcinoma (NPC) is a common malignant tumor of the head and neck, prevalent in regions such as Southern China and Southeast Asia. Radiotherapy serves as the primary clinical treatment for this carcinoma. However, resistance to radiotherapy is a fundamental cause of treatment failure and patient mortality, with the underlying mechanisms yet to be fully elucidated.

Background: Aloe-emodin (AE), a monomer derived from traditional Chinese medicine, has demonstrated remarkable efficacy in the clinical management of cognitive disorders. Ferroptosis (FPT), a specialized form of programmed cell death, plays a critical role in the pathological progression of various cognitive diseases.

Methods: This study explored the therapeutic potential of AE in a rat model of Wilson's disease cognitive impairments (WDCI) and examined whether these effects are mediated through the silencing information regulator 1 (SIRT1)-regulated FPT signaling pathway.

Spread through air spaces (STAS) is a recognized aggressive pattern in lung cancer, serving as a crucial risk factor for postoperative recurrence. However, its phenotype and related spatial structure have remained elusive. To address these limitations, we conducted a comprehensive study based on spatial data, analyzing over 30,000 spots from 14 non-STAS samples and one STAS sample.

Article Synopsis
  • The study investigates the relationship between sedentary behavior, physical activity, and chronic back pain, aiming to understand how these factors might predict chronic pain and brain changes.
  • Over an 8-year follow-up, the research found that individuals sitting for more than 6 hours a day had a 33% increased risk of chronic back pain compared to those sitting 2 hours or less, alongside effects on grey matter volume in various brain regions.
  • Engaging in moderate physical activity and reducing sedentary time were linked to lower back pain risk and improved brain health, indicating that replacing sedentary behavior with physical activity can be beneficial.

Article Synopsis
  • Intra-tumour immune infiltration significantly impacts the effectiveness of immunotherapy in non-small cell lung cancer (NSCLC), with two key patterns identified: immune exclusion (linked with myeloid cells) and immune activation (linked with plasma cells).
  • The study found that immune exclusion is associated with poor patient survival due to increased epithelial–mesenchymal transition and reduced immune activity, particularly marked by the presence of CD14+APOE+ cells and MMP7+ tumour cells.
  • Additionally, patients in an immunotherapy trial showing worse responses had higher levels of CD14+APOE+ and MMP7+ cells, revealing a critical link between these cell types and immune resistance mechanisms in NSCLC.

The elders in China's rural areas are facing challenges in maintaining agricultural production due to the outflow of rural laborers. The Transfer of land could alleviate the burden of land-based livelihoods for rural elders, but their decisions regarding land transfer are influenced by their social networks within the context of Chinese rural society. This study investigates how social networks impact the willingness of rural elders to transfer land.

The prevalence of severe mental disorders has been rising annually. Electroconvulsive therapy (ECT) is considered a valuable treatment option in psychiatry for conditions such as schizophrenia and medication-resistant depression, especially when other treatments have proven insufficient. ECT rapidly improves patients' mood, alleviates symptoms, and demonstrates significant therapeutic effects.

  • Neck pain is a common issue among military personnel, with studies showing a 1-year prevalence rate of up to 83% and a lifetime prevalence rate of 78%.
  • Factors such as age, neck mobility, shoulder pain, low back pain, and specific job conditions (like being a high-G pilot or prolonged flight time) are significantly linked to increased neck pain prevalence.
  • Addressing neck pain through targeted prevention and intervention based on identified risk factors is crucial for improving the health and readiness of military personnel.

Objectives: To investigate prognostic factors in patients with head and neck Mucoepidermoid Carcinoma (MEC), especially the impact of treatment modalities on survival.

Methods: Patients with primary head and neck MEC between 2000 and 2015 were obtained from the Surveillance, Epidemiology, and End Results (SEER) database. Prognostic factors related to Overall Survival (OS) and Cancer-Specific Survival (CSS), as well as the impact of treatments, were evaluated by multivariable Cox regression analysis.

  • Breast cancer is a serious illness and KCNK1 is a protein that might be important in how it spreads and gets worse.
  • Researchers found that higher levels of KCNK1 in breast cancer patients could mean they have a worse chance for recovery.
  • KCNK1 helps breast cancer cells grow and spread by influencing other chemicals in the body, which could help scientists find new ways to fight the disease.

Understanding the influences of climate change and human activities on vegetation change is the foundation for effective ecosystem management. Based on the 250 m MODIS-NDVI data from 2002 to 2020, we employed Theil-Sen Median trend analysis and the Mann-Kendall test to quantify vegetation change in Hunan Province. By combining with meteorological, nighttime light index, land cover and other data, residual analysis and correlation analysis, we examined the impacts of human activities and climate change on vegetation dynamics at both the pixel level and the county level.

Gradient macroporous polymers were produced by polymerization of emulsion templates comprising a continuous monomer phase and an internal aqueous template phase. To produce macroporous polymers with gradient composition, pore size, and foam density, we varied the template formulation, droplet size, and internal phase ratio of emulsion templates continuously and stacked those prior to polymerization. Using the outlined approach, it is possible to vary one property along the resulting macroporous polymer while retaining the other properties.

In hepatocellular carcinoma (HCC), classical cancer stem cells (CSC) markers were shared by normal stem cells, targeting which may hinder hepatic regeneration and cause liver failure. Additionally, the spatial structure of CSC still remained elusive. To address these limitations, we undertook a comprehensive study combining single-cell data (56,022 cells from 20 samples) and spatial data (38,191 spots from eight samples) to obtain CSC signature and uncover its spatial structure.
