Monotypic no longer: a new species of Panca Evans (Lepidoptera: Hesperiidae: Hesperiinae: Moncini) from South America Dolibaina, Diego Rodrigo; Eduardo Carneiro dos Santos; Mielke, Olaf Hermann Hendrik; Mirna Martins Casagrande; LAMAS, GERARDO ZOOTAXA (ONLINE), v. 4269, n. 1, p. 124-132, 2017 DOI resumo ... (en) A new species belonging to the previously monotypic genus Panca Evans, 1955, P. moseri Dolibaina, Carneiro & O. Mielke sp. nov., from grasslands areas of Peru, Bolivia and Brazil is described. Adults and male and female genitalia of the new species are illustrated, described in detail, and compared with the type species of the genus, Lerodea subpunctuli Hayward, 1934, and with its externally most similar and sympatric species, Vidius mictra Evans, 1955. The systematic position of the genus Panca and its association with lowland open natural habitats of South America are discussed.

Natural Killer Cell Assessment in Peripheral Circulation and Bronchoalveolar Lavage Fluid of Patients with Severe Sepsis: A Case Control Study SOUZA-FONSECA-GUIMARAES, PAULO; GUIMARAES, FERNANDO; NATÂNIA DE SOUZA-ARAUJO, CAROLINE; MARIA BOLDRINI LEITE, LIDIANE; CRISTINA SENEGAGLIA, ALEXANDRA; Anita Nishiyama; SOUZA-FONSECA-GUIMARAES, FERNANDO International Journal of Molecular Sciences (Online), v. 18, n. 3, p. 616 2017 DOI resumo ... Sepsis is a complex systemic inflammatory syndrome, the most common cause of which is attributed to systemic underlying bacterial infection. The complete mechanisms of the dynamic pro- and anti-inflammatory processes underlying the pathophysiology of sepsis remain poorly understood. Natural killer (NK) cells play a crucial role in the pathophysiology of sepsis, leading to exaggerated inflammation due their rapid response and production of pro-inflammatory cytokines such as interferon gamma (IFN-γ). Several studies have already shown that NK cells undergo lymphopenia in the peripheral blood of patients with sepsis. However, our understanding of the mechanisms behind its cellular trafficking and its role in disease development is restricted to studies in animal models. In this study, we aimed to compare the human NK cell subset (CD56bright or dim) levels in the peripheral blood and bronchoalveolar lavage (BAL) fluid of sepsis patients. We conducted a case-control study with a sample size consisting of 10 control patients and 23 sepsis patients enrolled at the Hospital Cajuru (Curitiba/PR, Brazil) from 2013 to 2015. Although we were able to confirm previous observations of peripheral blood lymphopenia, no significant differences were detected in NK cell levels in the BAL fluid of these patients. Overall, these findings strengthened the evidence that peripheral blood lymphopenia is likely to be associated with cell death as a consequence of sepsis.
