The Necessity of Lymphadenectomy for Non-Small Cell Lung Cancer Smaller Than 6 mm in Solid Size.

Background: This study aimed to evaluate the necessity of lymph node sampling for specific non-small cell lung cancer (NSCLC).

Methods: Patients with small-size (≤2 cm) NSCLC who underwent surgical resection between 2009 and 2022 were retrospectively screened. The characteristics of patients with nodal metastasis were demonstrated.

Role of waist circumferencetoheight ratio in assessing adiposity, predicting type 2 diabetes mellitus and other cardiometabolic diseases.

Although body mass index (BMI) is widely used as a simple tool to assess obesity, it has certain limitations and inaccuracies. It is known that visceral adipose tissue is closely related to cardiometabolic risks and all-cause mortality; however, precise measurement methods for visceral fat (magnetic resonance imaging and computed tomography) cannot be widely used. Thus, simple but accurate alternatives are valuable.

Synthesis and pharmacological evaluation of natural product diphyllin derivatives against head and neck squamous cell carcinoma.

Head and neck squamous cell carcinoma (HNSCC) is one of the most common malignant tumors, but clinical drug treatments are limited. The natural product diphyllin was identified as a lead compound suppressing the proliferation of HNSCC cells through phenotypic screening of natural product library. However, further developments of diphyllin as an anti-HNSCC agent were restricted by the weak bioactivity and poor metabolic stability.

Organic Crosslinked Tin Oxide Mitigating Buried Interface Defects for Efficient and Stable Perovskite Solar Cells.

Tin dioxide (SnO2) stands as a promising material for the electron transport layer (ETL) in perovskite solar cells (PSCs) attributed to its superlative optoelectronic properties. The attainment of superior power conversion efficiency hinges critically on the preparation of high-quality SnO2 thin films. However, conventional nanoparticle SnO2 colloids often suffer from inherent issues such as numerous oxygen vacancy defects and film non-uniformity.

Piezo1 aggravates ischemia/reperfusion-induced acute kidney injury by Ca-dependent calpain/HIF-1α/Notch signaling.

Macrophages play a vital role in the inflammation and repair processes of ischemia/reperfusion-induced acute kidney injury (IR-AKI). The mechanosensitive ion channel Piezo1 is significant in these inflammatory processes. However, the exact role of macrophage in IR-AKI is unknown.
