This study investigates the effects of the debranching time of waxy potato starch using pullulanase and recrystallization on particle morphology, debranching degree, and crystal structure. The results demonstrated that after gelatinization and debranching, the surface of the starch crystals became rough and uneven due to hydrolysis, with most particles showing a fragmented surface. The crystalline state was not significantly changed with debranching time.

Photothermal synergistic antibacterial therapy has emerged as a compelling approach for addressing antibiotic-resistant infections. In this study, lignosulfonate (LS) served dual roles as both a scaffolding template and a functional modifier in the fabrication of the lignin-polyaniline composite (LS-PANI). Subsequently, molybdenum disulfide (MoS) was integrated into LS-PANI through physical adsorption, resulting in the formation of MoS@LS-PANI.

Imatinib is the first-line targeted therapy for gastrointestinal stromal tumor (GIST), but resistance frequently occurs during treatment, limiting its efficacy and clinical application. We performed high-throughput sequencing of tissue specimens from imatinib-resistant GIST patients, and identified significantly high expression of polymeric immunoglobulin receptor (PIGR) in imatinib-resistant cell lines. Further investigation revealed that PIGR binds specifically to LINC00870.

The clinical efficacy of immune checkpoint blockade (ICB) therapy is significantly compromised in the metabolically disordered tumor microenvironment (TME), posing a formidable challenge that cannot be ignored in current antitumor strategies. In this study, TME-responsive nanoparticles (HMP1G NPs) loaded with 1-methyltryptophan (1-MT; an indoleamine 2,3-dioxygenase 1 [IDO1] inhibitor,) and S-nitrosoglutathione (GSNO; a nitric oxide donor) is developed to enhance the therapeutic efficacy of 1-MT-mediated ICB. The HMP1G NPs responded to H and glutathione in the TME, releasing Mn, GSNO, and 1-MT.

Article Synopsis
  • Extranodal extension (ENE) is a common feature in head and neck squamous cell carcinoma (HNSCC) that signifies tumor aggressiveness and raises the likelihood of local recurrence and distant metastasis.
  • ENE is utilized as a crucial indicator for prognosis and treatment decisions, yet there's a lack of consistent diagnostic standards for its assessment.
  • The article evaluates recent advancements in understanding the prognostic implications and diagnostic methods (both pathologic and radiologic) related to ENE in HNSCC.

The polarization splitter-rotator (PSR) is a key device for polarization processing in polarization diversity systems, which has wide applications in achieving polarization independence and mixed multiplexing. However, it remains a significant challenge to simultaneously achieve a better balance in bandwidth, crosstalk (CT), polarization extinction ratio (PER), and compact footprint of the PSR. In this article, a photonic crystal nanobeam (PCN) structure is introduced to PSR for large bandwidth and compact size, with a device length of only 104 µm.

We propose a low loss, wideband silicon transverse magnetic (TM) polarizer with high polarization extinction ratio and low reflection based on subwavelength grating. By arranging and optimizing a mutually perpendicular subwavelength grating with different duty cycles as the core and cladding, efficient waveguiding and radiation can be achieved for the TM and transverse electric (TE) injection, respectively. In simulation, the proposed TM polarizer has a footprint of 40µ×16.

All-solid-state lithium batteries with polymer electrolytes suffer from electrolyte decomposition and lithium dendrites because of the unstable electrode/electrolyte interfaces. Herein, a molecule crowding strategy is proposed to modulate the Li coordinated structure, thus in situ constructing the stable interfaces. Since 15-crown-5 possesses superior compatibility with polymer and electrostatic repulsion for anion of lithium salt, the anions are forced to crowd into a Li coordinated structure to weaken the Li coordination with polymer and boost the Li transport.

Efficient operation of control systems in robotics or autonomous driving targeting real-world navigation scenarios requires perception methods that allow them to understand and adapt to unstructured environments with good accuracy, adaptation, and generality, similar to humans. To address this need, we present a memristor-based differential neuromorphic computing, perceptual signal processing, and online adaptation method providing neuromorphic style adaptation to external sensory stimuli. The adaptation ability and generality of this method are confirmed in two application scenarios: object grasping and autonomous driving.

Article Synopsis
  • This study analyzed clinical data from 91 patients with T3 glottic laryngeal cancer to determine how different tumor invasion patterns affect prognosis after surgery.
  • Results indicated that posterior tumor invasion is linked to more complications and worse survival outcomes compared to anterior invasion, especially regarding laryngeal stenosis after partial laryngectomy.
  • The findings suggest that while partial laryngectomy can provide similar oncological results as total laryngectomy, further classification of tumor invasion patterns could help tailor treatment plans for better patient outcomes.
