Penetrating Abdominal Injury by a Large Stone [PDF]

, 2012
Penetrating trauma can be commonly caused by sharp objects. We report a case of penetrating injury of abdomen caused by a fairly large sized stone which is used for sharpening the objects or weapons.

Bimetallic Ca/Zn Nanoagonist Remould the Immunosuppressive Hepatocellular Carcinoma Microenvironment Following Incomplete Microwave Ablation via Pyroptosis and the STING Signaling Pathway

Advanced Science, EarlyView.
The multifunctional bimetallic Ca/Zn nanoagonist (PZH/Zn@CaNA) significantly downregulated the JAK2‐STAT3 signaling pathway, which effectively inhibited the proliferation and growth of HCC with incomplete microwave ablation. Furthermore, the released bimetallic ions (Ca2⁺ and Zn2⁺) synergistically enhanced oxidative stress‐mediated cytotoxicity ...

A Rare Presentation of Crohn's Disease [PDF]

, 2008
Free peritoneal perforation is a rare complication of Crohn's disease with a report of only 100 cases in the literature. It needs an emergency exploration and an unaware general surgeon is confounded in intraoperative decision-making.

Homogenization and norm resolvent convergence for elliptic operators in a strip perforated along a curve

, 2015
We consider an infinite planar straight strip perforated by small holes along a curve. In such domain, we consider a general second order elliptic operator subject to classical boundary conditions on the holes.

Neoadjuvant Chemotherapy With Cisplatin Up‐Regulates GSDMD to Enhance Oral Squamous Cell Carcinoma Metastasis Through MMP14‐Mediated EMT Activation

Advanced Science, EarlyView.
Oral squamous cell carcinoma cells exhibit upregulated expression of GSDMD upon exposure to low‐dose cisplatin chemotherapy, which subsequently interacts with MMP14 through its N‐terminal domain, activating the epithelial‒mesenchymal transition (EMT) process and promoting the lymph node metastasis of oral squamous cell carcinoma.

Cartilage‐Penetrating Framework Nucleic Acid Nanoparticles Ameliorate Osteoarthritis by Promoting Drug Delivery and Chondrocyte Uptake

Advanced Science, EarlyView.
Based on the poor cartilage penetration of tFNA, a novel tFNA‐2WL with excellent cartilage permeability and perfect chondrocyte endocytosis properties is designed and fabricated. As a result, tFNA‐2WL has a nearly seven‐fold increase in the penetration depth into the cartilage, with the same excellent cell entry properties as tFNA.

Revealing Dynamic Ion Transport in Tailorable Carbon Nano‐Skyscraper Electrodes

Advanced Science, EarlyView.
A 3D carbon nanotube electrode reveals how ions and electrons prioritize rapid transport over the shortest paths during charging. By creating a uniformly interconnected porous network, researchers improved electrode efficiency, surpassing traditional localized and gradient designs.

Model predictive control for current balancing in a four-phase buck converter [PDF]

, 2016
Multiphase buck topology offers smaller ripple current and lower component ratings. This, however, compromises unbalanced output current between each phase of an inductor which leads to over-current and inductor saturation issues.

MdDSK2a‐Like‐MdMTA Module Functions in Apple Cold Response via Regulating ROS Detoxification and Cell Wall Deposition

Advanced Science, EarlyView.
Under cold stress, MdDSK2a‐like is degraded via the 26S proteasome pathway, thereby alleviating the degradation of MdMTA induced by the 26S proteasome and autophagy pathways mediated by MdDSK2a‐like. The accumulated MdMTA increases the m6A levels of cold‐responsive genes, thereby contributing to increased ROS detoxification, deposition of cell wall, as

Mechanism of Fixed Pattern Noise of Micro‐Channel Plate Focusing on Cross‐Section of Single Channel

Advanced Electronic Materials, EarlyView.
The movement of secondary electrons to the phosphor screen after avalanche in microchannel plate (MCP) is influenced by the single channel cross‐sectional shape. The secondary electron beam emitted from MCP channels with different cross‐sectional shapes affects the energy and position upon striking the phosphor screen, directly impacting FPN (Fixed ...
