    Abstract Exosomes, a subset of extracellular vesicles (EVs, 30-200-nm diameter), serve as biomolecular snapshots of their cell of origin and vehicles for intercellular communication, playing roles in biological processes, including homeostasis maintenance and immune modulation. The large-scale processing of exosomes for use as therapeutic vectors has been proposed, but these applications are limited by impure, low-yield recoveries from cell culture milieu (CCM). Current isolation methods are also limited by tedious and laborious workflows, especially toward an isolation of EVs from CCM for therapeutic applications. Employed is a rapid (<10 min) EV isolation method on a capillary-channeled polymer fiber spin-down tip format. EVs are isolated from the CCM of suspension-adapted human embryonic kidney cells (HEK293), one of the candidate cell lines for commercial EV production. This batch solid-phase extraction technique allows 10

    Abstract A critical component of animal conservation in a changing world is an understanding of the physiological resilience of animals to different conditions. In many aquatic animals, hypoxia (low environmental oxygen levels) is a regular occurrence, but the likelihood and severity of hypoxia varies across habitats. Fast-flowing, stream-like habitats are never hypoxic, so long as flow is maintained. Do animals from such habitats retain the capacity to survive hypoxic conditions? We use aquatic frog tadpoles to test the effects of natural habitat on performance in hypoxia in an experimental framework, finding that stream-living tadpoles have reduced performance in hypoxia. Tadpoles also vary in lung presence, with some species able to breathe air during hypoxia. We found that among lunged tadpoles, air-breathing rates increase in hypoxia in pond-living species but not stream-living species. Lung presence was also found to influence hypoxia performance, as lungless, stream-living tadpoles were found to be especially vulnerable to hypoxia, while pond-living, lungless tadpoles appeared largely resilient to hypoxia. We consider the ramifications of our findings on conservation outlooks and strategies for frogs and their tadpoles, suggesting that stream-living tadpoles, and especially lungless, stream-living tadpoles, may be particularly at risk to factors that reduce stream flow. Thus, a primary goal for conservation and management of species with stream-living tadpoles should be the maintenance of year-round streamflow, which oxygenates waters and prevents hypoxia.

    Abstract In the emerging field of phyto-nanotechnology, 30–200 nm plant-derived extracellular vesicles (PDEVs) are now known to contain active biomolecules that mediate cell-to-cell communication processes in a manner very similar to exosomes in mammalian cells. The ability to deliver cargo across cellular membranes suggests that botanical systems could be used in the mass production of therapeutic vectors to transport exogenous molecules into human cells. The fundamental biochemical characteristics of PDEVs remain poorly understood due to the lack of efficient methods to isolate and characterize these nanovesicles. Described here is a rapid PDEV isolation method using a hydrophobic interaction chromatography (HIC)-based extraction performed on a capillary-channeled polymer (C-CP) fiber spin-down tip. The C-CP solid-phase extraction method is performed using a standard table-top centrifuge, enabling the isolation and concentration of PDEVs (>1 × 10¹⁰ particles from 100 μL of sample). PDEVs of 189 nm average diameter were obtained from 20 common fruit and vegetable stocks. The size, integrity, and purity of the recovered PDEVs were assessed using transmission electron microscopy (TEM), multi-angle light scattering (MALS), absorbance quantification, a protein purity assay, and an enzyme-linked immunosorbent assay (ELISA) to the PEN1 PDEV surface marker protein. The HIC C-CP tip isolation method allows for concentrated PDEV recoveries (up to 2 × 10¹¹ EVs) on reasonable time scales (<15 min) and low cost (<$1), with the purity and integrity fit for fundamental research and downstream applications.

    Abstract Exosomes, a subset of extracellular vesicles (EVs, 30–200‐nm diameter), serve as biomolecular snapshots of their cell of origin and vehicles for intercellular communication, playing roles in biological processes, including homeostasis maintenance and immune modulation. The large‐scale processing of exosomes for use as therapeutic vectors has been proposed, but these applications are limited by impure, low‐yield recoveries from cell culture milieu (CCM). Current isolation methods are also limited by tedious and laborious workflows, especially toward an isolation of EVs from CCM for therapeutic applications. Employed is a rapid (<10 min) EV isolation method on a capillary‐channeled polymer fiber spin‐down tip format. EVs are isolated from the CCM of suspension‐adapted human embryonic kidney cells (HEK293), one of the candidate cell lines for commercial EV production. This batch solid‐phase extraction technique allows 10¹² EVs to be obtained from only 100‐µl aliquots of milieu, processed using a benchtop centrifuge. The tip‐isolated EVs were characterized using transmission electron microscopy, multi‐angle light scattering, absorbance quantification, an enzyme‐linked immunosorbent assay to tetraspanin marker proteins, and a protein purity assay. It is believed that the demonstrated approach has immediate relevance in research and analytical laboratories, with opportunities for production‐level scale‐up projected.

    Abstract Objective: This paper updates clinicians and service leaders on evidence bases relevant to rehabilitation for older Australians with mental illness.
    Methods: Narrative review of literature and relevant public domain data supported by reflections on NSW service development.
    Results: There is a paucity of high-quality evidence regarding mental health rehabilitation in older people. Available evidence supports integrating lessons from physical healthcare with adaptations of 'adult' mental health rehabilitation. Adaptation is required to respond to the specific needs, strengths and service use of older people with mental illness. Challenges for older people include ageism, increased physical and cognitive comorbidities, lower access to mental health services and earlier residential aged care entry. Strengths of older people include an ongoing desire for recovery, ongoing developmental change and often closer connections with carers and GPs. Evidence is consistent with evaluation of relevant NSW service models and initiatives including the Pathways to Community Living Initiative. Integration of recovery-oriented practice and wellness models may provide a framework for future innovative inpatient and community-based models.
    Conclusions: There is sufficient evidence to guide development of models of rehabilitation with older people, but innovation and evaluation are essential if older people are to have equal opportunities in their recovery journeys.
