The ferromagnetism, and therefore the safety in a magnetic resonance (MR) examination, of the most widely available air gun pellets has been tested. While many are made of lead and are not ferromagnetic, some contain steel and are deflected strongly in a magnetic field. There must therefore be careful consideration before undertaking MR examinations of patients with embedded air gun pellets.

A general strategy to achieve see-through devices through the micro-structuring of colored functional materials.
Nat Commun

Irrespective of the specific see-through device, obtaining optimal transparency remains the primary goal. In this work, we introduce a general strategy to enhance the transparency of various see-through devices. We achieve this by structuring the colored functional materials into imperceptible three-dimensional mesh lines, addressing a common challenge in multi-layer structures where each layer causes a reduction in transparency due to their color or opacity.

With the applications of in situ X-ray diffraction (XRD), electrical - measurement, and ambient pressure hard X-ray photoelectron spectroscopy (AP-HAXPES), the characteristics of the topotactic phase transition of LaCoO (LCO) thin films are examined. XRD measurements show clear evidence of structural phase transition (SPT) of the LCO thin films from the perovskite (PV) LaCoO to the brownmillerite (BM) LaCoO phases through the intermediate LaCoO phase at a temperature of 350 °C under high-vacuum conditions, ∼10 mbar. The reverse SPT from BM to PV phases is also found under ambient pressure (>100 mbar) of air near 100 °C.

Department of Central Sterile Supply, Hainan General Hospital, Hainan Affiliated Hospital of Hainan Medical University, Haikou, 570311, People's Republic of China.
Objective: This study aimed to investigate whether noise exposure in hospital sterile supply centers exacerbated the psychological burden on staff, potentially mediated by concerns about physiological health.
Methods: Between July 5 and August 4, 2023, 308 staffs from central sterile supply departments in 30 hospitals in Hainan were chosen by convenient sampling method. They completed self-administered questionnaires to assess noise exposure status and used the Self-Reporting Inventory-90 to quantify the psychological state of staff across three dimensions: somatization, anxiety, and sleep and diet.
Development of a novel gut microphysiological system that facilitates assessment of drug absorption kinetics in gut.

There is an urgent need for novel methods that can accurately predict intestinal absorption of orally administered drugs in humans. This study aimed to evaluate the potential of a novel gut microphysiological system (MPS), gut MPS/Fluid3D-X, to assess the intestinal absorption of drugs in humans. The gut MPS/Fluid3D-X model was constructed using a newly developed flow-controllable and dimethylpolysiloxane-free MPS device (Fluid3D-X).

Article Synopsis
- High-pressure injection injuries in the hand often result from industrial tools like paint guns or air compressors, typically affecting laborers' non-dominant hands and causing damage that’s often underestimated despite appearing as a small puncture wound.
- These injuries can cause severe complications such as neurovascular compromise and acute compartment syndrome due to the spread of injected materials that can be toxic and lead to further tissue damage or infections.
- A presentation of three cases highlights urgent surgery needs for patients who experienced severe pain and swelling after different injected substances, leading to procedures for decompression, irrigation, and tissue removal to prevent serious outcomes.
