- Objectives: To evaluate the feasibility and adherence to home delivery (HD) of pemetrexed maintenance treatment in patients with advanced non-squamous non-small cell lung cancer (nsqNSCLC). Materials and methods: Exploratory, prospective, single-arm, Phase II study in advanced nsqNSCLC patients, with an Eastern Cooperative Oncology Group (ECOG) performance status of 0/1 that did not progress after 4 first-line induction cycles of a platinum doublet. The first cycle of pemetrexed (500 mg/m(2)) was hospital administered, further cycles were HD until progressive disease or discontinuation. Feasibility was assessed by the adherence rate to HD (probability of reversion to hospital administration or treatment discontinuation due to HD) as primary endpoint, and by health-related quality-of-life (HRQoL: EQ-5D, lung cancer symptom scale [LCSS]), satisfaction with HD, overall survival (OS), and safety. Results: 52 patients (UK and Sweden) received a median of 4 (range 1-19) pemetrexed maintenance cycles. Adherence rate up to Cycle 6 was 98.0% (95% confidence interval [CI]: 86.4%, 99.7%). All but 2 patients remained on HD. 1 patient discontinued after Cycle 1 (patient decision), and 1 after Cycle 6 (noncompliance with oral dexamethasone). 87% (33/38) of the patients preferred home to hospital treatment and in 90% (28/31) of cases, physicians were satisfied with distant management of patients. During HD Cycles 2-4 mean change from baseline ranged from 3.0 to 7.7 for EQ-5D visual analog scale. The 6-month OS rate was 73% (95% CI: 58%, 83%). 1 patient had an HD-related adverse event (device-related infection, Grade 2) and 1 patient died after Cycle 1, before HD, due to a possibly drug-related atypical pneumonia. Conclusion: HD of pemetrexed maintenance treatment in patients with advanced nsqNSCLC was feasible, safe, and preferred by patients, while maintaining HRQoL. Physicians were satisfied with distant patient management. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

- Societal Impact Statement Plant and fungal specimens provide the auditable evidence that a particular organism occurred at a particular place, and at a particular point in time, verifying past occurrence and distribution. They also document the aspects of human exploration and culture. Collectively specimens form a global asset with significant potential for new uses to help address societal and environmental challenges. Collections also serve as a platform to engage and educate a broad range of stakeholders from the academic to the public, strengthening engagement and understanding of plant and fungal diversity-the basis of life on Earth. SummaryWe provide a global review of the current state of plant and fungal collections including herbaria and fungaria, botanic gardens, fungal culture collections, and biobanks. The review focuses on the numbers of collections, major taxonomic group and species level coverage, geographical representation and the extent to which the data from collections are digitally accessible. We identify the major gaps in these collections and in digital data. We also consider what collection types need to be further developed to support research, such as environmental DNA and cryopreservation of desiccation-sensitive seeds. Around 31% of vascular plant species are represented in botanic gardens, and 17% of known fungal species are held in culture collections, both these living collections showing a bias toward northern temperate taxa. Only 21% of preserved collections are available via the Global Biodiversity Information Facility (GBIF) with Asia, central and north Africa and Amazonia being relatively under-represented. Supporting long-term collection facilities in biodiverse areas should be considered by governmental and international aid agencies, in addition to short-term project funding. Institutions should consider how best to speed up digitization of collections and to disseminate all data via aggregators such as GBIF, which will greatly facilitate use, research, and community curation to improve quality. There needs to be greater alignment between biodiversity informatics initiatives and standards to allow more comprehensive analysis of collections data and to facilitate linkage of extended information, facilitating broader use. Much can be achieved with greater coordination through existing initiatives and strengthening relationships with users.

- Intranasal administration of peptide Acl-9[4Y], based on the N-terminal epitope of myelin basic protein, can induce CD4(+) T cell tolerance, and suppress experimental autoimmune encephalomyelitis induction. The peptide-induced regulatory T (PI-T-Reg) cells failed to produce IL-2, but expressed IL-10 in response to Ag and could suppress naive T cell responses in vitro. Analysis of Jak-STAT signaling pathways revealed that the activation of Jak1, STAT3, and STAT5 were induced in tolerant T cells after Ag stimulation in vivo. In addition, the expression of suppressor of cytokine signaling 3 was induced in tolerant T cells, suggesting that cytokines regulate the tolerant state of the PI-T-Reg cells. Stimulation of PI-T-Reg cells in vitro with IL-10 induced Jak1 and STAT3 activation, but not STAT5, suggesting that IL-10 is important, but not the only cytokine involved in the development of T cell tolerance. Although IL-2 expression was deficient, stimulation with IL-2 in vitro induced Jak1 and STAT5 activation in PI-T-Reg cells, restored their proliferative response to antigenic stimulation, and abrogated PI-T-Reg-mediated suppression in vitro. However, the addition of IL-2 could not suppress IL-10 expression, and the IL-2 gene remained inactive. After withdrawal of IL-2, the PI-T-Reg cells regained their nonproliferative state and suppressive ability. These results underline the ability of the immune system to maintain tolerance to autoantigens, but at the same time having the ability to overcome the suppressive phenotype of tolerant T cells by cytokines, such as IL-2, during the protective immune response to infection.
