OBJECTIVES : Addressing disparities in low back pain care (LBP) is an important yet largely unaddressed issue. One avenue to addressing disparities, recommended by clinical guidelines, is to ensure that LBP information is culturally appropriate. Our objectives were, first, to develop LBP information that was culturally appropriate for Aboriginal Australians living in a rural area and, second, to compare this to traditional information. METHODS : The overall information development process was guided by a "cultural security" framework and included partnerships between Aboriginal/non-Aboriginal investigators, a synthesis of research evidence, and participation of a project steering group consisting of local Aboriginal people...

INTRODUCTION: Using a birthing ball (BB) is an exercise form that is growing in popularity. Improved delivery outcomes have been recently reported with as little a 6-8 hours of training per week; however, little is known regarding lower and higher training levels. The aim of the current study was to document whether more time spent training with a BB resulted in improved delivery outcomes for the mother and the newborn. METHODS: This quasi-experimental study was conducted with a sample of women who participated in one to 28 supervised exercise classes during pregnancy according to the Ballon Forme program offered in non-clinical settings (http://ballonforme...

As cancer development involves pathological vessel formation, 16 angiogenesis markers were evaluated as potential ovarian cancer (OC) biomarkers. Blood samples collected from 172 patients were divided based on histopathological result: OC (n = 38), borderline ovarian tumours (n = 6), non-malignant ovarian tumours (n = 62), healthy controls (n = 50) and 16 patients were excluded. Sixteen angiogenesis markers were measured using BioPlex Pro Human Cancer Biomarker Panel 1 immunoassay. Additionally, concentrations of cancer antigen 125 (CA125) and human epididymis protein 4 (HE4) were measured in patients with adnexal masses using electrochemiluminescence immunoassay...

We describe the design of lubricating and wear protecting fluids based on synergistic mixtures of bottlebrushes (BB) and linear polymers solutions. To illustrate this concept we used hyaluronic acid (HA) - a naturally occurring linear polyelectrolyte, and a water soluble synthetic BB polymer. Individually, these two polymers exhibit poor wear protecting capabilities compared to saline solutions. Mixture of the two polymers in pure water or in saline allows to drastically increase wear protection of surfaces under a wide range of shearing conditions...

WNT-5A is a secreted growth factor that belongs to the non-canonical members of the Wingless-related MMTV-integration family. Previous studies pointed to a connection between WNT-5A and the fibrogenic factor TGF-β warranting further studies into the functional role of WNT-5A in liver fibrosis. Therefore, we studied WNT-5A expressions in mouse and human fibrotic livers and examined the relation between WNT-5A and various fibrosis-associated growth factors, cytokines and extracellular matrix proteins. WNT-5A gene and protein expressions were significantly increased in fibrotic mouse and human livers compared to healthy...

BACKGROUND: The increasing interest in platelet-rich plasma (PRP) based therapies is as yet accompanied by inconsistent information regarding nearly all aspects of handling and application. Among these storage stability of processed platelet-rich products may be the basis for a more flexible application mode. The objective of this study was (1) to estimate the storage stability of growth factors platelet derived growth factor BB (PDGF-BB) and transforming growth factor ß1 (TGF-ß1) in both, a single-step softspin centrifugation-based pure-PRP (P-PRP, ACP®), and a gravity filtration system-based leukocyte-rich-PRP (L-PRP, E-PET), over a six hours time span after preparation at room temperature and (2) to identify possible factors influencing these growth factor concentrations in an equine model...
