AI Article Synopsis

  • Laser capture microdissection (LCM) is a valuable technique in medical research, allowing the collection of specific cell populations for molecular analysis under a microscope.
  • Adapting LCM procedures to fit different analysis platforms is crucial; this study focuses on refining LCM for preparing fresh frozen samples for NanoString analysis in a mouse mammary gland carcinoma model.
  • The optimized LCM workflow yielded high-quality RNA samples suitable for NanoString, enabling precise detection of target genes and their related pathways, demonstrating the compatibility of NanoString with LCM.

Article Abstract

Laser capture microdissection (LCM) of tissue is an established tool in medical research for collection of distinguished cell populations under direct microscopic visualization for molecular analysis. LCM samples have been successfully analyzed in a number of genomic and proteomic downstream molecular applications. However, LCM sample collection and preparation procedure has to be adapted to each downstream analysis platform. In this present manuscript we describe in detail the adaptation of LCM methodology for the collection and preparation of fresh frozen samples for NanoString analysis based on a study of a model of mouse mammary gland carcinoma and its lung metastasis. Our adaptation of LCM sample preparation and workflow to the requirements of the NanoString platform allowed acquiring samples with high RNA quality. The NanoString analysis of such samples provided sensitive detection of genes of interest and their associated molecular pathways. NanoString is a reliable gene expression analysis platform that can be effectively coupled with LCM.

Investigating the hydrolysis of complex carbohydrates with salivary α-amylase.

Food Res Int

February 2025

Department of Food Science, University of Copenhagen, Rolighedsvej 26, 1958 Frederiksberg C, Denmark. Electronic address:

Currently, little is known about how complex carbohydrates (maltodextrins) with varying degrees of polymerisation (DP) and molecular branching interact with α-amylase in human saliva and the associated amounts and structures of generated reducing sugars. Therefore, this study aimed to investigate salivary α-amylase and the subsequent reducing sugars generated with complex carbohydrate stimuli. A secondary aim was to investigate reducing sugar generation and complex carbohydrate taste sensitivity.

Effective decontamination of hospital surfaces is crucial to protect workers from antineoplastic drugs (ADs) since dermal absorption is the main exposure route to these hazardous medicinal products. Sampling after daily cleaning in oncologic settings from a tertiary hospital was initially performed and exhibited low contamination levels; however, cyclophosphamide was still found (up to 957 pg/cm) above the guidance value (100 pg/cm) in four locations, evidencing the need to properly assess and update the cleaning protocols. Then, cleaning efficiencies of six solutions and different protocols were evaluated (including, for the first time, four commercial cleaning solutions/disinfectants not designed specifically for AD removal) after deliberate contamination of three model surfaces with 13 pharmaceuticals: bicalutamide, capecitabine, cyclophosphamide, cyproterone, doxorubicin, etoposide, flutamide, ifosfamide, imatinib, megestrol, mycophenolate mofetil, paclitaxel, and prednisone.

In Situ Preparation of Silver Nanoparticles/Organophilic-Clay/Polyethylene Glycol Nanocomposites for the Reduction of Organic Pollutants.

Polymers (Basel)

December 2024

Catalysis Research Group (CRG), Department of Chemistry, College of Science, King Khalid University, P.O. Box 9004, Abha 61413, Saudi Arabia.

This work focuses on the preparation and application of silver nanoparticles/organophilic clay/polyethylene glycol for the catalytic reduction of the contaminants methylene blue (MB) and 4-nitrophenol (4-NP) in a simple and binary system. Algerian clay was subjected to a series of treatments including acid treatment, ion exchange with the surfactant hexadecyltrimethylammonium bromide (HTABr), immobilization of polyethylene glycol polymer, and finally dispersion of AgNPs. The molecular weight of polyethylene glycol was varied (100, 200, and 4000) to study its effect on the stabilization of silver nanoparticles (AgNPs) and the catalytic activity of the resulting samples.

4-Cyano-4'-ethoxybiphenyl (EBCN) is a representative cyano liquid crystal monomer (LCM). While prior studies have documented the widespread occurrence of LCMs in diverse environmental and biological samples, research on their reproductive effects in vivo remains limited. This study employed 35-day and 70-day exposure models in mice to assess the short-term and long-term effects of environmentally relevant concentrations of EBCN on testicular health.
