A Sprague-Dawley rat model was utilized to elucidate perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS) and perfluorohexanesulfonic acid (PFHxS) toxicokinetics with a goal of developing an in vivo approach for quantifying PFAS relative bioavailability in impacted soil. Following single dose administration (gavage) of ∼ 0.2-2000 µg kg BW of PFOA, PFOS or PFHxS, differences in PFAS blood, organ and excreta concentrations were observed over 120 h although linear dose responses were determined for area under the blood plasma time curves (AUC; PFOA, PFHxS), liver accumulation (LA: PFOS) and urinary excretion (UE; PFOA, PFHxS).

Enhancing the pharmacokinetics of abiraterone acetate through lipid-based formulations: addressing solubility and food effect challenges.

Drug Deliv Transl Res

November 2024

Centre for Pharmaceutical Innovation, UniSA Clinical and Health Sciences, University of South Australia, Adelaide, South Australia, Australia.

Abiraterone acetate, a prodrug of abiraterone, is an effective antiandrogen for treating metastatic prostate cancer. However, its poor aqueous solubility restricts oral bioavailability to under 10% in fasted conditions. Additionally, its pharmacokinetics are significantly influenced by food intake, leading to variable exposure that can impact treatment safety and efficacy.

Background: Childhood height is commonly used to measure children's health and nutritional status. It is used to define stunting, where a child is considered stunted if their height is shorter than two standard deviations below the Child Growth Standards median. Studies have shown that genetic and environmental factors contribute to childhood height, so understanding these contributions is important for stunting research.

  • Breast cancer continues to be a major global health issue, with increasing VUS complicating diagnosis in Australia’s healthcare system.
  • This study examined VUS data from 11 familial cancer centers, revealing that 4% of variants might be reclassified as pathogenic and 80% as benign.
  • Surveys indicated that there are challenges in VUS management due to limited resources, suggesting the need for routine reviews to improve patient care and communication between laboratories and cancer centers.

Oxytocin is a key hormone in the transition to motherhood. The maternal endogenous oxytocin system facilitates many physiological and biological adaptations, including breastfeeding, maternal wellbeing, and brain plasticity. Additionally, maternal endogenous oxytocin works as a finetuned orchestrator prior to, during, and after the birth of a child to support birth progression and mother-infant bonding.

Surface Chemistry Induced IgG Unfolding and Modulation of Immune Responses.

ACS Appl Mater Interfaces

September 2024

College of Medicine and Public Health, Flinders University, Bedford Park, South Australia 5042, Australia.

Immunoglobulin G (IgG) comprises a significant portion of the protein corona that forms on biomaterial surfaces and holds a pivotal role in modulating host immune responses. To shed light on the important relationship between biomaterial surface functionality, IgG adsorption, and innate immune responses, we prepared, using plasma deposition, four surface coatings with specific chemistries, wettability, and charge. We found that nitrogen-containing coatings such as these deposited from allylamine (AM) and 2-methyl-2-oxazoline (POX) cause the greatest IgG unfolding, while hydrophilic acrylic acid (AC) surfaces allowed for the retention of the protein structure.

A translational framework to DELIVER nanomedicines to the clinic.

Nat Nanotechnol

November 2024

Department of Biomaterials and Biomedical Technology, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands.

Nanomedicines have created a paradigm shift in healthcare. Yet fundamental barriers still exist that prevent or delay the clinical translation of nanomedicines. Critical hurdles inhibiting clinical success include poor understanding of nanomedicines' physicochemical properties, limited exposure in the cell or tissue of interest, poor reproducibility of preclinical outcomes in clinical trials, and biocompatibility concerns.

Micronuclei (MN) are a nuclear abnormality that occurs when chromosome fragments or whole chromosomes are not properly segregated during mitosis and consequently are excluded from the main nuclei and wrapped within nuclear membrane to form small nuclei. This maldistribution of genetic material leads to abnormal cellular genomes which may increase risk of developmental defects, cancers, and accelerated aging. Despite the potential importance of MN as biomarkers of genotoxicity, very little was known about the optimal way to measure MN in humans, the normal ranges of values of MN in healthy humans and the prospective association of MN with developmental and degenerative diseases prior to the 1980's.

Background: Enterobacter species are included among the normal human gut microflora and persist in a diverse range of other environmental niches. They have become important opportunistic nosocomial pathogens known to harbour plasmid-mediated multi-class antimicrobial resistance (AMR) determinants. Global AMR surveillance of Enterobacterales isolates shows the genus is second to Klebsiella in terms of frequency of carbapenem resistance.

Genetic heterogeneity in ovarian cancer indicates the need for personalised treatment approaches. Currently, very few G-protein coupled receptors (GPCRs) have been investigated for active targeting with nanomedicines such as antibody-conjugated drugs and drug-loaded nanoparticles, highlighting a neglected potential to develop personalised treatment. To address the genetic heterogeneity of ovarian cancer, a future personalised approach could include the identification of unique GPCRs expressed in cancer biopsies, matched with personalised GPCR-targeted nanomedicines, for the delivery of lethal drugs to tumour tissue before, during and after surgery.

Article Synopsis
  • Micronucleus (MN) assays using buccal cells are effective for assessing genetic damage in workers exposed to genotoxic metals, with most studies showing increased MN and nuclear anomalies among various occupations.
  • A comprehensive review of 73 studies, mainly from South East Asia and South America, highlighted the need for better evaluation methods, as many studies lacked thorough assessments of genetic stability and cytotoxic effects.
  • The data suggests that MN assays can provide valuable insights into chromosomal damage from metal exposure, complementing current chemical analysis and potentially enhancing workplace safety by reflecting biological impacts.
