Rural health services are challenging to manage, a situation perhaps exacerbated by necessity to comply with one-size-fits-all performance frameworks designed for larger services. This raises the questions: do we know what rural health services are doing that is valuable and how should that be evaluated? Twenty-eight qualitative interviews with CEOs and staff of seven Victorian rural health services were conducted, exploring what they value about their 'best practice'. Themes emergent from analysis were compared with 19 government-produced health planning and performance documents...

Dissemination of Extended spectrum β-lactamases (ESBL) Enterobacteriaceae is a major medical threat. Vegetables and fruits, which are usually consumed raw, are a very suitable pathway for the spread of these bacteria from farm-to-fork. However, limited information exists regarding resistant bacteria and epidemic clones that are disseminated in vegetables and tap water in South America. We processed a total of 90 samples in triplicate of nine typically consumed raw vegetables from a central municipal market, and tap water samples were processed from twenty-one locations in Quito, Ecuador...

Three polysaccharide fractions were isolated from blackberry wine. The crude extract BWPs was obtained with ethanol precipitation and freeze-thawing process, it was then submitted to Fehling treatment, giving soluble BWPFs and insoluble BWPFp fractions. These fractions were characterized by Gas Chromatography-Mass Spectrometry (GC-MS) and Nuclear Magnetic Resonance (NMR). Major polysaccharides were identified for each fraction: mannan, type II arabinogalactan and type I rhamnogalacturonan for BWPs, a mannan formed by a major chain of α-Manp(1 → 6)-linked units, O-2 substituted with α-d-Manp(1 → 2)-linked side chains for BWPFp and a AG II formed by a major chain of β-d-Galp(1 → 3)-linked, substituted at O-6 by side chains of the β-d-Galp(1 → 6)-linked, which then are substituted at O-3 by non-reducing units of α-l-Araf and a RG I, formed by [→4)-α-d-GalpA-(1 → 2)-α-l-Rhap-(1→]n for BWPFs...

The aim was to evaluate antioxidants from berries as replacement food additives for inhibition of lipid and protein oxidation in meat and meat products, since meats are highly susceptible to oxidation. Oxidation can be delayed/retarded by synthetic antioxidants with phenolic structures (e.g. butylated hydroxytoluene). However, new natural alternatives are needed for synthetic antioxidants due to the controversy regarding their possible negative health effects and consumers' demand for more 'natural' food additives...

Effects of 1-methylcyclopropene (1-MCP) and vacuum precooling on quality and antioxidant properties of blackberries ( Rubus spp.) were evaluated using one-way analysis of variance, principal component analysis (PCA), partial least squares (PLS), and path analysis. Results showed that the activities of antioxidant enzymes were enhanced by both 1-MCP treatment and vacuum precooling. PCA could discriminate 1-MCP treated fruit and the vacuum precooled fruit and showed that the radical-scavenging activities in vacuum precooled fruit were higher than those in 1-MCP treated fruit...

Glycation is associated with several neurodegenerative disorders, including Alzheimer's disease (AD), where it potentiates the aggregation and toxicity of proteins such as β-amyloid (Aβ). Published studies support the anti-glycation and neuroprotective effects of several polyphenol-rich fruits, including berries, which are rich in anthocyanins. Herein, blackberry, black raspberry, blueberry, cranberry, red raspberry, and strawberry extracts were evaluated for: (1) total phenolic and anthocyanins contents, (2) free radical (DPPH) scavenging and reactive carbonyl species (methylglyoxal; MGO) trapping, (3) anti-glycation (using BSA-fructose and BSA-MGO models), (4) anti-Aβ aggregation (using thermal- and MGO-induced fibrillation models), and, (5) murine microglia (BV-2) neuroprotective properties...

Further improvements in Photodynamic therapy (PDT) necessitate that the dye targets more selectively tumour tissues or neovascularization than healthy cells. Different enzymes such as matrix metalloproteinases (MMPs) are overexpressed in tumour areas. Among these MMPs, gelatinases (MMP-2 and MMP-9) and its activator MMP-14 are known to play a key role in tumour angiogenesis and the growth of many cancers such as glioblastoma multiforme (GBM), an aggressive malignant tumour of the brain. These last years, the concept of photodynamic molecular beacons (PMB) became interesting for controlling the photosensitizer's ability to generate singlet oxygen (1 O2 ) close to target biomolecules as MMPs...

Anthocyanins are potential food colorants due to their color, low toxicity and biological properties. However, the low chemical stability of anthocyanins has limited their use. In this work, the thermal stability of cyanidin-3-O-glucoside (cy3glc) (major blackberry anthocyanin) and blackberry purees through molecular inclusion with β-cyclodextrin (β-CD) was assessed. Complexation with β-CD showed a thermal stabilization of cy3glc, resulting on a decrease of the degradation rate constant (k) and in several alterations in the cy3glc-β-CD DSC thermogram...
