Clay-based hemostatic agents: Fabrication, mechanisms, and evidence.

Biomater Adv

August 2025

School of Mechanical Engineering and Mechanics, Xiangtan University, Xiangtan 411105, China. Electronic address:

Hemorrhagic control remains a serious concern in emergency medicine and combat trauma management, where achieving rapid hemostasis significantly impacts patient survival outcomes. While conventional interventions including direct manual compression and tourniquet application demonstrate clinical efficacy in routine scenarios, their limitations become apparent when managing catastrophic hemorrhage or anatomically complex injuries. Mineral-based hemostatic agents, particularly clay-derived rapid hemostats, have emerged as a promising therapeutic modality that synergizes ancestral wound management practices with contemporary material engineering.

The interfacial mutual solubility can result in a random distribution of donor and acceptor materials during the spin-coating step in the fabrication of planar heterojunction (PHJ) near-infrared (NIR) organic phototransistors. In this case, deep trap states are induced by acceptors, accelerating electron-hole recombination, ultimately impairing the photoresponsivity of the phototransistor. To solve this issue, a controllable mutual dissolution layer (formed by co-solvent treatment) combined with a diffusion interface layer (formed by the solvent vapor annealing (SVA) method) was introduced to achieve a more ordered arrangement of donors and acceptors, thereby enhancing the electrical performance of PHJ-based NIR phototransistors.

Dual-perspective decoupling network for kidney tumor segmentation on CT images.

Neural Netw

August 2025

Hunan Provincial Key Laboratory of Intelligent Computing and Language Information Processing, Hunan Normal University, Changsha, 410081, China. Electronic address:

The key challenges in kidney tumor segmentation include unpredictable location, high similarity among objects, and variability in boundaries. Existing approaches mostly handle these challenges from an object-agnostic perspective or a single decoupling perspective, which limits their ability to address all the aforementioned challenges. To tackle these problems, we propose a Dual-perspective Decoupling Network (DDNet), which consists of the Dual-perspective Decoupling Module (DDM) and the Edge Refinement Module (ERM).

August 2025

State Key Laboratory of Bioactive Molecules and Druggability Assessment, the First Affiliated Hospital, Jinan University, Guangzhou, 510632, China.

Hypoxia can substantially impact clinical outcomes in patients with head and neck cancer (HNC) by promoting tumor invasion, metastasis, immune escape, and therapy resistance. Given the growing interest in targeting hypoxia for cancer therapy, noninvasive methods are needed to accurately detect hypoxia and evaluate the tumor response to treatment. This review summarizes recent advances in hypoxia-targeted probes and imaging techniques, emphasizing their imaging mechanisms, strengths, and limitations.

Macrophage polarization of tumor-associated macrophages (TAMs) is critical for cancer development, while the impact of N-methyladenosine (mA) on the polarization of TAMs remains poorly understood. This study investigated the function of mA modification in macrophages and demonstrated that methyltransferase-like 3 (METTL3) can downregulate the alternatively activated macrophages (M2) polarization level of TAMs via suppression of snail family transcriptional repressor 1 (Snail) protein translation. Independent of protein stability, METTL3 restrained the translation efficiency of Snail in an mA-dependent manner, thereby inhibiting M2 polarization of TAMs.

Molecular Insights into the Effect of S262 Phosphorylation on the Binding of Tau to Microtubule and Its Self-Aggregation.

J Phys Chem B

August 2025

Department Sport and Exercise Science, College of Education, Zhejiang University, 866 Yuhangtang Road, Hangzhou, Zhejiang 310007, People's Republic of China.

Aberrantly phosphorylated Tau protein dissociating from microtubule and aggregating into intracellular fibrillary inclusions is closely associated with tauopathies, including Alzheimer's disease, chronic traumatic encephalopathy, and corticobasal degeneration. Previous experiments reported that the tauopathies-associated post-translational modification serine 262 phosphorylation (S262p) is linked to the Tau-microtubule interaction and Tau self-aggregation. However, the underlying molecular mechanism is not well understood.

Department of Otorhinolaryngology Head and Neck Surgery, The First People's Hospital of Chenzhou, Chenzhou, 423000, China; Department of Otorhinolaryngology Head and Neck Surgery, The First Affiliated Hospital of Xiangnan University, Chenzhou, 423000, China. Electronic address:

In this study, we explored the role of IGF2BP2 in nasopharyngeal carcinoma (NPC) and its link to ferroptosis, a form of regulated cell death associated with cancer progression. Through bioinformatics analysis of the GSE53819 dataset, we identified differentially expressed genes, performed survival analysis, and conducted pan-cancer studies, revealing that IGF2BP2 is overexpressed in NPC and associated with poor prognosis. Clinical sample analysis and cellular experiments confirmed IGF2BP2 upregulation in NPC and its ability to induce ferroptosis when knocked down.
