The son of Greek parents, Kostas Murkudis grew up in Dresden and studied fashion design in Berlin. His early career was marked by an intensive collaboration with Helmut Lang. After winning the Phillip Morris Design award, Murkudis struck out on his own. This book shows 30 years of his creativity, inviting the reader for the first time to get as close as possible to his artistic approach.

BackgroundSeronegative villous atrophy (SNVA) is commonly attributed to coeliac disease (CD). However, there are other causes of SNVA. More recently angiotensin-2-receptor-blockers (A2RBs) have been reported as an association but data on SNVA have been limited to centres evaluating complex case referrals and not SNVA in general.ObjectivesTo provide clinical outcomes and associations in a large prospective study overseeing all newcomers with SNVA.DesignOver a 15-year period (2000–2015) we evaluated 200 adult patients with SNVA at a UK centre. A diagnosis of either seronegative CD (SNCD) or seronegative non-CD (SN-non-CD) was reached. Baseline comparisons were made between the groups, with 343 seropositive CD subjects serving as controls.ResultsOf the 200 SNVA cases, SNCD represented 31% (n=62) and SN-non-CD 69% (n=138). The human leucocyte antigen (HLA)-DQ2 and/or DQ8 genotype was present in 61%, with a 51% positive predictive value for SNCD. The breakdown of identifiable causes in the SN-non-CD group comprised infections (27%, n=54), inflammatory/immune-mediated disorders (17.5%, n=35) and drugs (6.5%, n=13; two cases related to A2RBs). However, no cause was found in 18% (n=36) and of these 72% (n=26/36) spontaneously normalised duodenal histology while consuming a gluten-enriched diet. Following multivariable logistic regression analysis an independent factor associated with SN-non-CD was non-white ethnicity (OR 10.8, 95% CI 2.2 to 52.8); in fact, 66% of non-whites had GI infections. On immunohistochemistry all groups stained positive for CD8-T-cytotoxic intraepithelial lymphocytes. However, additional CD4-T helper intraepithelial lymphocytes were occasionally seen in SN-non-CD mimicking the changes associated with refractory CD.ConclusionsMost patients with SNVA do not have CD, in particular those who are not white. Furthermore, a subgroup with no obvious aetiology will show spontaneous histological resolution while consuming gluten. These findings suggest caution in empirically prescribing a gluten-free diet without investigation.

Melioidosis is a potentially fatal disease caused by the bacterium, Burkholderia pseudomallei. The current study was carried out to determine the mechanisms involved in the development of protective immunity in a murine model of melioidosis. Following intravenous infection with B. pseudomallei, both C57BL/6 and BALB/c mice demonstrated delayed‐type hypersensitivity responses and lymphocyte proliferation towards B. pseudomallei antigens, indicating the generation of B. pseudomallei‐specific lymphocytes. Adoptive transfer of these lymphocytes to naïve C57BL/6 mice was demonstrated by a delayed‐type hypersensitivity response. Mice were not protected from a subsequent lethal challenge with a highly virulent strain of B. pseudomallei, suggesting that a single intravenous dose of the bacterium is insufficient to induce a protective adaptive immune response. Attempts to induce resistance in susceptible BALB/c mice used repetitive low‐dose exposure to live B. pseudomallei. Immune responses and resistance following subcutaneous immunization with live B. pseudomallei were compared with exposure to heat‐killed, culture filtrate and sonicated B. pseudomallei antigens. Compared to heat‐killed B. pseudomallei, significant protection was generated in BALB/c mice following immunization with live bacteria. Our studies also demonstrate that the type of immune response generated in vivo is influenced by the antigenic preparation of B. pseudomallei used for immunization.

Melioidosis is a bacterial infection caused by Burkholderia pseudomallei. The aim of this study was to determine whether a cell-mediated adaptive immune response against B. pseudomallei developed in patients who had recovered from melioidosis. Lymphocyte proliferation assays were done on peripheral blood mononuclear cells from patients (n=13) and control subjects (n=10) to determine the lymphocyte response to B. pseudomallei antigens. Production of interferon-γ and interleukin-10 was also determined. Activation of T cell subsets was assessed by fluorescence-activated cell sorter analysis, using antibodies to CD4, CD8, and CD69 antigens. Lymphocyte proliferation and interferon-γ production in response to B. pseudomallei antigens were significantly higher (P<.001 for both) in patients than in control subjects. There was also an increase in the percentage of activated CD4+ (P<.004) and activated CD8+ T cells (P<.035) in cell cultures from patients. The development of such a cell-mediated immune response in patients may be essential for their survival

Melioidosis is a disease of the tropics caused by the facultative intracellular bacterium Burkholderia pseudomallei. In human infection, increased levels of IFN‐γ in addition to the chemokines interferon‐γ‐inducible protein 10 (IP‐10) and monocyte interferon‐γ‐inducible protein (Mig) have been demonstrated. However, the role of these and other chemokines in the pathogenesis of melioidosis remains unknown. Using BALB/c and C57BL/6 mice as models of the acute and chronic forms of human melioidosis, the induction of mRNA was assessed for various chemokines and CSF (G‐CSF, M‐CSF, GM‐CSF, IP‐10, Mig, RANTES, MCP‐1, KC and MIP‐2) in spleen and liver following B. pseudomallei infection. Patterns of chemokine and CSF induction were similar in liver and spleen; however, responses were typically greater in spleen, which reflected higher tissue bacterial loads. In BALB/c mice, high‐level expression of mRNA for all chemokines and CSF investigated was demonstrated at day 3 postinfection, correlating with peak bacterial load and extensive infiltration of leucocytes. In contrast, increased mRNA expression and bacterial numbers in C57BL/6 mice were greatest between 4 and 14 days following infection. This paralleled increases in the size and number of abscesses in liver and spleen of C57BL/6 mice at days 3 and 14 postinfection. Earlier induction of cytokine‐induced neutrophil chemoattractant (KC), macrophage inflammatory protein‐2 (MIP‐2), monocyte chemoattractant protein‐1 (MCP‐1), granulocyte‐macrophage CSF (GM‐CSF) and macrophage CSF (M‐CSF) mRNA was demonstrated in spleen, while MIP‐2, MCP‐1, IP‐10 and Mig were demonstrated in liver of BALB/c mice when compared to spleen and liver of C57BL/6. The magnitude of cellular responses observed in the tissue correlated with increased levels of the chemokines and CSF investigated, as well as bacterial load. Compared with C57BL/6 mice, greater infiltration of neutrophils was observed in liver and spleen of BALB/c mice at day 3. In contrast, early lesions in C57BL/6 mice predominantly comprised macrophages. These results suggest that the inability of BALB/c mice to contain the infection at sites of inflammation may underlie the susceptible phenotype of this mouse strain towards B. pseudomallei infection.

Mellioidosis is an infectious disease that has become increasingly more widespread in humans. Here, Barnes and Ketheesan describe preliminary efforts to understand mellioidosis, a tropical disease that could be used as a bioterrorism agent.

Nearly a billion people depend on tropical seascapes. The need to ensure sustainable use of these vital areas is recognised, as one of 17 policy commitments made by world leaders, in Sustainable Development Goal (SDG) 14 (‘Life below Water’) of the United Nations. SDG 14 seeks to secure marine sustainability by 2030. In a time of increasing social-ecological unpredictability and risk, scientists and policymakers working towards SDG 14 in the Asia–Pacific region need to know: (1) How are seascapes changing? (2) What can global society do about these changes? and (3) How can science and society together achieve sustainable seascape futures? Through a horizon scan, we identified nine emerging research priorities that clarify potential research contributions to marine sustainability in locations with high coral reef abundance. They include research on seascape geological and biological evolution and adaptation; elucidating drivers and mechanisms of change; understanding how seascape functions and services are produced, and how people depend on them; costs, benefits, and trade-offs to people in changing seascapes; improving seascape technologies and practices; learning to govern and manage seascapes for all; sustainable use, justice, and human well-being; bridging communities and epistemologies for innovative, equitable, and scale-crossing solutions; and informing resilient seascape futures through modelling and synthesis. Researchers can contribute to the sustainability of tropical seascapes by co-developing transdisciplinary understandings of people and ecosystems, emphasising the importance of equity and justice, and improving knowledge of key cross-scale and cross-level processes, feedbacks, and thresholds.

Background As greater numbers of us are living longer, it is increasingly important to understand how we can age healthily. Although old age is often stereotyped as a time of declining mental abilities and inflexibility, cognitive neuroscience reveals that older adults use neural and cognitive resources flexibly, recruiting novel neural regions and cognitive processes when necessary. Our aim in this project is to understand how age-related changes to neural structure and function interact to support cognitive abilities across the lifespan. Methods/Design We are recruiting a population-based cohort of 3000 adults aged 18 and over into Stage 1 of the project, where they complete an interview including health and lifestyle questions, a core cognitive assessment, and a self-completed questionnaire of lifetime experiences and physical activity. Of those interviewed, 700 participants aged 18-87 (100 per age decile) continue to Stage 2 where they undergo cognitive testing and provide measures of brain structure and function. Cognition is assessed across multiple domains including attention and executive control, language, memory, emotion, action control and learning. A subset of 280 adults return for in-depth neurocognitive assessment in Stage 3, using functional neuroimaging experiments across our key cognitive domains. Formal statistical models will be used to examine the changes that occur with healthy ageing, and to evaluate age-related reorganisation in terms of cognitive and neural functions invoked to compensate for overall age-related brain structural decline. Taken together the three stages provide deep phenotyping that will allow us to measure neural activity and flexibility during performance across a number of core cognitive functions. This approach offers hypothesis-driven insights into the relationship between brain and behaviour in healthy ageing that are relevant to the general population. Discussion Our study is a unique resource of neuroimaging and cognitive measures relevant to change across the adult lifespan. Because we focus on normal age-related changes, our results may contribute to changing views about the ageing process, lead to targeted interventions, and reveal how normal ageing relates to frail ageing in clinicopathological conditions such as Alzheimer's disease.
