An exploratory qualitative study of inter-agency health and social service partnerships focused on Aboriginal and Torres Strait Islander clients.

Background: The siloed nature of the health and social service system threatens access for clients engaging numerous organisations. Many Aboriginal and Torres Strait Islander people face adverse circumstances which contribute to multiple health and social needs. Effective relationships between health and social services are integral to coordinated service provision to meet the diverse needs of Aboriginal and Torres Strait Islander clients.

Evaluating the Scope of Services and Monetary Impact of Charity Medical Clinics in North Texas.

Introduction/objectives: The cost of medical services is a major barrier to healthcare accessibility for underserved populations in the United States. Community charity medical clinics help address this disparity by providing free or reduced-cost care for the medically underinsured; however, their economic and public health contributions are unknown. The objective of this study was to evaluate the scope of services and monetary impact of 4 community charity medical clinics in North Texas, with one of the largest medically underinsured populations in the United States.

Healing the Past by Nurturing the Future: trauma-aware, healing-informed care to improve support for Aboriginal and Torres Strait Islander families - implementation and evaluation study protocol.

Introduction: Complex trauma can have serious impacts on the health and well-being of Aboriginal and Torres Strait Islander families. The perinatal period represents a 'critical window' for recovery and transforming cycles of trauma into cycles of healing. The Healing the Past by Nurturing the Future (HPNF) project aims to implement and evaluate a programme of strategies to improve support for Aboriginal and Torres Strait islander families experiencing complex trauma.

Digital droplet PCR analysis of organoids generated from mouse mammary tumors demonstrates proof-of-concept capture of tumor heterogeneity.

Breast cancer metastases exhibit many different genetic alterations, including copy number amplifications (CNA). CNA are genetic alterations that are increasingly becoming relevant to breast oncology clinical practice. Here we identify CNA in metastatic breast tumor samples using publicly available datasets and characterize their expression and function using a metastatic mouse model of breast cancer.

Exploring self-determined solutions to service and system challenges to promote social and emotional wellbeing in Aboriginal and Torres Strait Islander people: a qualitative study.

Introduction: Many Aboriginal and Torres Strait Islander people living on Kaurna Country in northern Adelaide experience adverse health and social circumstances. The study sought to understand challenges facing Aboriginal and Torres Strait Islander communities and identify solutions for the health and social service system to promote social and emotional wellbeing.

Methods: This qualitative study applied Indigenous methodologies undertaken with Aboriginal and Torres Strait Islander governance and leadership.

Organoid generation from mouse mammary tumors captures the genetic heterogeneity of clinically relevant copy number alterations.

Breast cancer metastases exhibit many different genetic alterations, including copy number amplifications. Using publicly available datasets, we identify copy number amplifications in metastatic breast tumor samples and using our organoid-based metastasis assays, and we validate FGFR1 is amplified in collectively migrating organoids. Because the heterogeneity of breast tumors is increasingly becoming relevant to clinical practice, we demonstrate our organoid method captures genetic heterogeneity of individual tumors.

Generating and Imaging Mouse and Human Epithelial Organoids from Normal and Tumor Mammary Tissue Without Passaging.

Organoids are a reliable method for modeling organ tissue due to their self-organizing properties and retention of function and architecture after propagation from primary tissue or stem cells. This method of organoid generation forgoes single-cell differentiation through multiple passages and instead uses differential centrifugation to isolate mammary epithelial organoids from mechanically and enzymatically dissociated tissues. This protocol provides a streamlined technique for rapidly producing small and large epithelial organoids from both mouse and human mammary tissue in addition to techniques for organoid embedding in collagen and basement extracellular matrix.

TK216 targets microtubules in Ewing sarcoma cells.

Ewing sarcoma (EWS) is a pediatric malignancy driven by the EWSR1-FLI1 fusion protein formed by the chromosomal translocation t(11; 22). The small molecule TK216 was developed as a first-in-class direct EWSR1-FLI1 inhibitor and is in phase II clinical trials in combination with vincristine for patients with EWS. However, TK216 exhibits anti-cancer activity against cancer cell lines and xenografts that do not express EWSR1-FLI1, and the mechanism underlying cytotoxicity remains unresolved.

Exploring the readiness of senior doctors and nurses to assess and address patients' social needs in the hospital setting.

Background: Adverse social circumstances are a key factor in health outcomes. Hospitals are an opportune setting for assessing and addressing the unmet social needs of patients, however, the readiness of healthcare workers in hospitals to undertake such tasks requires further exploration in the Australian context. This study aimed to generate a theory of doctors' and nurses' readiness to assess and address patients' social needs in a hospital setting.

TM1385 from Thermotoga maritima functions as a phosphoglucose isomerase via cis-enediol-based mechanism with active site redundancy.

Phosphoglucose isomerases (PGIs) belong to a class of enzymes that catalyze the reversible isomerization of glucose-6-phosphate to fructose-6-phosphate. PGIs are crucial in glycolysis and gluconeogenesis pathways and proposed as serving additional extracellular functions in eukaryotic organisms. The phosphoglucose isomerase function of TM1385, a previously uncharacterized protein from Thermotoga maritima, was hypothesized based on structural similarity to established PGI crystal structures and computational docking.

Mathematical modeling of positron emission tomography (PET) data to assess radiofluoride transport in living plants following petiolar administration.

Background: Ion transport is a fundamental physiological process that can be studied non-invasively in living plants with radiotracer imaging methods. Fluoride is a known phytotoxic pollutant and understanding its transport in plants after leaf absorption is of interest to those in agricultural areas near industrial sources of airborne fluoride. Here we report the novel use of a commercial, high-resolution, animal positron emission tomography (PET) scanner to trace a bolus of [(18)F]fluoride administered via bisected petioles of Brassica oleracea, an established model species, to simulate whole plant uptake of atmospheric fluoride.
