AI Article Synopsis

  • The text discusses the need for a sensitive technique to monitor the distribution of metallic nanoparticles in cancer therapy.
  • Inductively coupled plasma mass spectrometry (ICP-MS) is highlighted as an effective tool for tracking these metal components.
  • A standardized method for processing biological samples and preparing controls is presented, initially using gold nanoparticles, but adaptable for other metals as well.

Article Abstract

The increasing exploration of metallic nanoparticles for use as cancer therapeutic agents necessitates a sensitive technique to track the clearance and distribution of the material once introduced into a living system. Inductively coupled plasma mass spectrometry (ICP-MS) provides a sensitive and selective tool for tracking the distribution of metal components from these nanotherapeutics. This chapter presents a standardized method for processing biological matrices, ensuring complete homogenization of tissues, and outlines the preparation of appropriate standards and controls. The method described herein utilized gold nanoparticle-treated samples; however, the method can easily be applied to the analysis of other metals.

A novel ionic liquid MALDI matrix, 3-aminoquinoline/2',4',6'-trihydroxyacetophenone monohydrate (3-AQ/THAP), was developed for the rapid qualitative and quantitative detection of miRNA from biological samples. Compared to the traditional matrix 2,5-dihydroxybenzoic acid (DHB) and previously reported oligonucleotide-specific matrices, such as 3-aminopicolinic acid (3-APA), 3-hydroxypicolinic acid (3-HPA), and 6-aza-2-thiothymine (ATT), the 3-AQ/THAP matrix offers several advantages. It produces fewer alkali metal adduct peaks, exhibits higher sensitivity, and ensures better spot-to-spot repeatability.

An effective approach for the immobilization and protection of biological entities is their encapsulation via the in situ synthesis of metal-organic frameworks (MOFs). To ensure the preservation of the bioentities, mild synthetic conditions, including aqueous media and ambient conditions (temperature and pressure), are preferred. In this study, we investigated the synthesis of various aluminum polycarboxylate-based MOFs, including the fumarate, terephthalate, amino-terephthalate, and muconate forms of MIL-53(Al), as well as the MIL-110 and MIL-160 MOF types.

Cancer is a complex and heterogeneous disease, and accurate cancer subtyping can significantly improve patient survival rates. The complexity of cancer spans multiple omics levels, and analyzing multi-omics data for cancer subtyping is a focus of considerable attention. However, extracting complementary information from different omics data sources and adaptively integrating them remains a major challenge.

It is well-known that the use of vocabulary in phenotype treatments is often inconsistent. An earlier survey of biologists who create or use phenotypic characters revealed that this lack of standardization leads to ambiguities, frustrating both the consumers and producers of phenotypic data. Such ambiguities are challenging for biologists, and more so for Artificial Intelligence, to resolve.

Background: Informal caregivers of individuals with acquired brain injury (ABI) often lack adequate preparedness for caregiving. Caregiver burden may reduce preparedness, with anxiety potentially mediating this relationship. However, these associations remain unclear.
