: The coronary slow flow phenomenon (CSFP) is an angiographic finding characterised by the delayed passage of contrast through the coronary arteries, despite the absence of obstructive coronary artery disease (defined as less than 50% narrowing of the vessel lumen). Patients with the CSFP experience recurrent angina, for which there are limited evidence-based therapies. Ticagrelor may serve as an effective anti-anginal therapy for these patients by increasing adenosine levels, which could alleviate coronary microvascular dysfunction and its associated angina due to its vasodilatory properties.

Characterising the role of enolase in a stable Small Colony Variant of Staphylococcus aureus isolated from a diabetic foot infection patient with osteomyelitis.

Microb Pathog

November 2024

Department of Molecular and Biomedical Sciences, School of Biological Sciences, University of Adelaide, Adelaide, South Australia, Australia; Australian Centre for Antimicrobial Resistance Ecology (ACARE), The University of Adelaide, Adelaide, South Australia, Australia; Research Centre for Infectious Diseases (RCID), The University of Adelaide, Adelaide, Australia. Electronic address:

The switch to alternate cell types by Staphylococcus aureus creates sub-populations even within an active population, that are highly resilient, tolerant to antibiotics and lack clinical symptoms of infection. These cells present a challenge for clinical treatment where even after initial intervention has seemingly cleared the infection, these alternate cell types persist within tissue to revert and cause disease. Small colony variants (SCV) are a cell type which facilitate persistent infection but clinically isolated SCVs are often unstable in laboratory conditions.

Novel diagnostic approaches and management of coronary microvascular dysfunction.

Am J Prev Cardiol

September 2024

Translational and Clinical Research Institute, Faculty of Medical Sciences, NewcastleUniversity, Newcastle upon Tyne, UK.

Article Synopsis
  • - Ischaemic heart disease (IHD) has mainly been linked to obstructive coronary artery disease (CAD), but over 50% of patients have non-obstructive coronary arteries, leading to interest in angina due to these non-obstructive conditions (ANOCA/INOCA).
  • - INOCA includes various causes like coronary microvascular dysfunction (CMD) and vasospastic angina, with CMD resulting from poor vasodilatory capacity of small blood vessels; it is particularly more common in women and linked to worse heart health outcomes.
  • - Research has improved the understanding and classification of these conditions, including the use of advanced imaging and testing methods to better diagnose CMD and inform treatment strategies for affected patients. *

Introduction: Common major co-formulants in glyphosate-based herbicides, polyethoxylated tallow amine surfactants, are suspected of being more toxic than glyphosate, contributing to the toxicity in humans. However, limited information exists on using polyethoxylated tallow amine concentrations to predict clinical outcomes. We investigated if plasma concentrations of glyphosate, its metabolite and polyethoxylated tallow amines can predict acute kidney injury and case fatality in glyphosate poisoning.

The working diagnosis Myocardial Infarction with Nonobstructive Coronary Arteries (MINOCA) is being increasingly recognized with the common use of high-sensitivity troponins and coronary angiography, accounting for 5% to 10% of all acute myocardial infarction presentations. Cardiac magnetic resonance (CMR) imaging is pivotal in patients presenting with suspected MINOCA, mainly to delineate those with a nonischemic cause, for example, myocarditis and Takotsubo syndrome, from those with true ischemic myocardial infarction, that is, MINOCA. The optimal timing for CMR imaging in patients with suspected MINOCA has been uncertain and, until recently, not been examined prospectively.

A key characteristic of cancer cells is their ability to induce changes in their microenvironment that render it permissive to tumor growth, invasion and metastasis. Indeed, these changes are required for tumor progression. Consequently, the tumor microenvironment is emerging as a key source of new targets against cancer, with novel therapies aimed at reversing tumor-promoting changes, reinstating a tumor-hostile microenvironment and suppressing disease progression.

Pancreatic ductal adenocarcinoma (PDAC) is characterized by increasing fibrosis, which can enhance tumor progression and spread. Here, we undertook an unbiased temporal assessment of the matrisome of the highly metastatic KPC (, , ) and poorly metastatic KPC (, , ) genetically engineered mouse models of pancreatic cancer using mass spectrometry proteomics. Our assessment at early-, mid-, and late-stage disease reveals an increased abundance of nidogen-2 (NID2) in the KPC model compared to KPC, with further validation showing that NID2 is primarily expressed by cancer-associated fibroblasts (CAFs).
