Computational staining of CD3/CD20 positive lymphocytes in human tissues with experimental confirmation in a genetically engineered mouse model.

Introduction: Immune dysregulation plays a major role in cancer progression. The quantification of lymphocytic spatial inflammation may enable spatial system biology, improve understanding of therapeutic resistance, and contribute to prognostic imaging biomarkers.

Methods: In this paper, we propose a knowledge-guided deep learning framework to measure the lymphocytic spatial architecture on human H&E tissue, where the fidelity of training labels is maximized through single-cell resolution image registration of H&E to IHC.

A Semi-Quantitative Approach to Nontarget Compositional Analysis of Complex Samples.

Nontarget analysis (NTA) by liquid chromatography coupled to high-resolution mass spectrometry improves the capacity to comprehend the molecular composition of complex mixtures compared to targeted analysis techniques. However, the detection of unknown compounds means that quantification in NTA is challenging. This study proposes a new semi-quantitative methodology for use in the NTA of organic aerosol.

Functional characterization and optimization of protein expression in shuttle plasmids.

Unlabelled: Oral spirochetes are among a small group of keystone pathogens contributing to dysregulation of periodontal tissue homeostasis, leading to breakdown of the tissue and bone supporting the teeth in periodontal disease. Of the greater than sixty oral species and phylotypes, is one of the few that can be grown in culture and the only one in which genetic manipulation has been shown to be practicable. is thus a model organism for studying spirochete metabolic processes, interactions with other microbes and host cell and tissue responses relevant to oral diseases as well as venereal and nonvenereal treponematoses.

Establishing the TSH reference intervals for healthy adults aged over 70 years: the Australian ASPREE cohort study.

Objectives: As thyroid disorders are common amongst the elderly, this study aims to evaluate the reference interval (RI) for thyroid stimulating hormone (TSH) in healthy adults aged 70 years and over.

Methods: A proposed RI was determined from the Australian participants of the ASPirin in Reducing Events in the Elderly (ASPREE) randomised trial. Participants had no history of cardiovascular disease, thyroid cancer, dementia, or life-threatening illnesses.

Evaluation of the long-term protection conferred by an organosilicon-based disinfectant formulation against bacterial contamination of surfaces.

Aims: The aim of this work was to evaluate the efficacy of an organosilicon-based, commercially available antimicrobial formulation in the My-shield® product line against bacterial surface contamination.

Methods And Results: The antimicrobial product was tested in vitro for its long-term persistence on surfaces and effectiveness against Staphylococcus aureus biofilms in comparison to 70% ethanol and 0.1% or 0.
