Integrated O2 and H2 Gas Therapy via Microneedle‐Assisted Photocatalytic Water Splitting for Accelerating Diabetic Full‐Thickness Skin Wound Healing

Advanced Science, EarlyView.
A concept of integrated O2 and H2 gas therapy is achieved using a gas‐producing material. PMP nanoparticles, fabricated from platinum, MIL‐101(Fe)‐NH2, and phosphotungstic acid, are integrated into bilayer gelatin methacryloyl microneedles for transdermal delivery. These microneedles enable integrated O2 and H2 gas therapy and promote wound healing via

Retroperitoneal migration of a self-inflicted ballpoint pen via the urethra

International Brazilian Journal of Urology, 2006
Numerous accounts documenting the introduction of foreign bodies into the urinary bladder have been reported. These foreign bodies are typically self-inserted via urethral but migration from adjacent organs by an ulcerative process and penetrating ...

An Injectable ROS‐Responsive Nanozyme Hydrogel Regulates the Uterine Microenvironment to Prevent Intrauterine Adhesions

Advanced Science, EarlyView.
The injectable CeTA@GPP hydrogel is administered via intrauterine injection, forming a protective barrier. In the high ROS inflammatory microenvironment of injured endometrium, boronate ester cleavage triggers responsive CeTA release and local enrichment.

Distinct Cleavage Trajectories Mediated by DNA and RNA Substrate in Argonaute From Methanocaldococcus Fervens

Advanced Science, EarlyView.
This study characterizes MfAgo, an enzyme exhibiting highly efficient DNA‐guided DNA and RNA cleavage capability. Precise RNA cleavage strictly requires dimerization to stabilize the PIWI‐loop region, while its robust DNA cleavage functions in a dimerization‐independent manner.

Metallic Foreign Body Penetrating the Carotid Sheath: A Case Report [PDF]

, 2011
Foreign bodies are a common problem seen in otolaryngological practice. Of the reported foreign bodies, metallic foreign bodies are a rare entity. One of the least common complications of foreign body ingestion is penetration and migration. We describe a

Spontaneous migration of periocular glass foreign body: An interesting case

Kerala Journal of Ophthalmology, 2017
The occurrence of soft-tissue foreign bodies (FBs) in and around the orbit is often seen after trauma. Wound exploration and removal of the embedded materials is the standard of care. Relevant investigations help to detect retained FBs in suspected cases.

Migration, trade, and foreign investment in Mexico [PDF]

Part of the rationale for the North American Free Trade Agreement (NAFTA) was that it would increase trade and foreign direct investment (FDI) flows, creating jobs and reducing migration to the United States.

Macrophage Dab1 Links Early Hypoxia to Adaptive Angiogenesis to Drive Peripheral Nerve Repair

Advanced Science, EarlyView.
Schematic diagram illustrating the Dab1‐linked hypoxia signaling pathway that accelerates angiogenesis and consequent nerve regeneration. Following PNI, a hypoxic microenvironment develops. Hypoxia induces macrophage Dab1 phosphorylation, resulting in NHE‐1 upregulation, HIF‐1α stabilization, and VEGF‐A expression. This cascade promotes angiogenesis in

Smart Bioinks for 4D Bioprinting: Requirements, Design, and Applications

Advanced Science, EarlyView.
Smart bioinks empower 4D‐bioprinted constructs to dynamically adapt and remodel in response to stimuli, effectively biomimicking native tissues. Artificial Intelligence (AI) and Machine Learning (ML) play a guiding role in their rational design by optimizing relevant properties.
