Inorganic nanozymes hold promise for biomolecule sensing but face challenges like complex fabrication, toxicity, and low sustainability, limiting their use. To overcome these, a sustainable organic nanozyme (OA nanozyme) was created using amino acids and a biocompatible polymer for effective histamine detection. The OA nanozyme exhibits peroxidase-like activity and was fabricated through a single chelation/polymer entanglement method, enabling rapid production (within 3 h) with uniform morphology (≤100 nm diameter) and a negative surface charge at neutral pH.

Even at trace concentrations, micropollutants, including pesticides and pharmaceuticals, pose considerable ecological risks, and the increasing presence of synthetic chemical substances in aquatic systems has emerged as a growing concern. Moreover, limited machine-learning (ML) approaches exist for analyzing environmental data, and the increasing complexity of ML models has made it challenging to understand predictor-outcome relationships. In particular, understanding complex interactions among multiple variables remains challenging.

Background: Post-cardiac arrest care advancements have improved resuscitation outcomes, but many survivors still face severe neurological deficits or death from brain injury. Herein, we propose a consistent prognosis prediction approach using magnetic resonance imaging (MRI) to analyze anatomical regions represented by the gray and white matter, and subsequently apply it on computed tomography (CT) to calculate the gray-white matter ratio (GWR). We compared this novel method with traditional measures to validate its ability to predict the prognosis of patients resuscitated after cardiac arrest.

Objective: It is difficult to identify disease entities underlying lymphadenopathy in the head and neck region based solely on imaging. This often results in metastatic squamous cell carcinoma (Sqcc)-induced lymphadenopathy being mistaken for lymphoma. This study aimed to analyze clinical characteristics and computed tomographic features that aid in distinguishing between metastatic Sqcc and lymphoma when lymphadenopathy resembles a large solitary lymphoma.

Isothermal nucleic acid amplification tests, NAATs, such as reverse transcription-loop-mediated isothermal amplification (RT-LAMP), offer promising capabilities to perform real-time semiquantitative detection of viral pathogens. These tests provide rapid results, utilize simple instrumentation for single-temperature reactions, support efficient user workflows, and are suitable for field use. Herein, we present a novel and robust method for real-time monitoring of HIV-1 RNA RT-LAMP utilizing a novel implementation of particle diffusometry (PD), a diffusivity quantification technique using fluorescent particles, to quantify viral concentration in nuclease-free water.

  • - Xanthogranulomatous osteomyelitis (XO) is a rare bone disease that appears as an osteolytic lesion, and it's crucial to distinguish it from other similar conditions like bone tumors.
  • - A 23-year-old woman presented with pelvic pain and febrile episodes, leading to the discovery of an osteolytic lesion in the pubic bone, which was later confirmed to be caused by an Aspergillus fungal infection after surgical removal.
  • - This case highlights the importance of considering fungal infections in XO cases and suggests that specific antifungal treatments should be included in the management plan, as XO can occur due to such infections despite being predominantly associated with bacteria.

Olfactory dysfunction, influenced by factors such as aging and environmental stress, is linked to various neurological disorders. The olfactory bulb's connections to brain areas like the hypothalamus, piriform cortex, entorhinal cortex, and limbic system make olfactory dysfunction a contributor to a range of neuropathological conditions. Recent research has underscored that olfactory deficits are prevalent in individuals with both metabolic syndrome and dementia.
