ToF-SIMS Parallel Imaging MS/MS of Lead Soaps in Embedded Paint Cross Sections.

In the field of cultural heritage, and more specifically in oil paintings, the ability to unambiguously identify and locate metal soaps is of great interest for a better understanding of painting degradation. Here, we demonstrate the use of a Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) instrument capable of tandem mass spectrometry imaging for the unambiguous identification and localization of lead soaps in cross sections of samples of old oil paintings at high spatial resolution. It is shown that the specific fragmentation pattern of lead soaps is dictated by the loss of the lead ion and that fragmentation occurs on the hydrocarbon chains of the fatty acids.

Biliary-enteric anastomosis is a common surgical procedure for benign and malignant pathologies involving bile ducts, pancreas and duodenum, as well as during liver transplantation. Imaging is key in detecting potential complications. Ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and nuclear scintigraphy provide complementary information.

Individual differences in how the brain responds to novelty are present from infancy. A common method of studying novelty processing is through event-related potentials (ERPs). While ERPs possess millisecond precision, spatial resolution remains poor, especially in infancy.

Persistent hiccups are rare but can serve as an early symptom of underlying conditions, including pulmonary infections and cerebrovascular disorders. This case highlights hiccups as a presenting symptom of bronchopneumonia in a hemodialysis patient and explores the effective use of chlorpromazine and Hange-koboku-to (HKT) as symptomatic therapies. Given the potential association of hiccups with neurological conditions, this case underscores the need for comprehensive diagnostic evaluation.

Real-time monitoring and anomaly detection are essential in healthcare to ensure safe conditions for patients and maintain the integrity of medical data samples. The majority of existing systems, despite improvements in healthcare technologies, cannot capture the spatial and temporal patterns of multimodal data simultaneously, process high Volume data in real-time, and ensure the privacy of patients' identity effectively. In this work, we handle these limitations by proposing a complete approach that uses state-of-the-art deep learning and data processing architectures to realize resilient anomaly detection in healthcare systems.
