The study of multi-modal communication has only recently been extended to innate and learned interactions between flowers and their animal visitors, and usually only to pollinators. Here we studied the relevance of floral scent and visual display of a night blooming, putatively hawkmoth-pollinated plant Oenothera acaulis （Onagraceae） in the attraction of non-native cockroaches blatta orientalis （blattodea： blattidae）, which function as facultative floral larcenists in coastal habitats of central Chile. We experimentally decoupled visual （corolla） and olfactory （fragrance） stimuli by presenting paper corollas and green mesh bags, with or without a freshly-picked natural flower inside. We then contrasted the behavioral responses of roaches in these treatments with those to the natural combination of traits in actual flowers and their respective control treatments, measuring the roaches＇ frequency of first visits, mean and total residence time spent in each treatment. The roaches primarily used olfactory cues when approaching O. acaulis flowers at two biologically relevant spatial scales. In addition, the presence of conspecific roaches had a strong influence on recruitment to the experimental arena, increasing the statistical differences among treatments. Our results suggest a primacy of floral fragrance over visual stimuli in the foraging responses of b. orientalis. Olfactory cues were necessary and sufficient to attract the roaches, and the visual cues presented in our manipulations only marginally increased their attraction within a 20 cm diameter of the stimulus. The full spectrum of floral visitation behavior was not elicited by the artificial flowers, suggesting the need for additional tactile or contact chemosensory stimuli not provided by paper. Although the nitrogenous scent compounds that we found in O. acaulis flowers are almost exclusively found in hawkmoth-pollinated flowers, the attractiveness of these compounds to a non-native, facultative flower-visiti

Inflammatory bowel diseases(IbDs) are chronic disorders of modern society, requiring management strategies aimed at prolonging an active life and establishing the exact etiology and *** idiopathic diseases have environmental, genetic,immunologic, inflammatory, and oxidative stress components. On the one hand, recent advances have shown that abnormal immune reactions against the microorganisms of the intestinal flora are responsible for the inflammation in genetically susceptible individuals. On the other hand, in addition to T helper cell-type(Th) 1 and Th2 immune responses,other subsets of T cells, namely regulatory T cells and Th17 maintained by IL-23 are likely to develop IbD. IL-23 acts on innate immune system members and also facilitates the expansion and maintenance of Th17 cells. The IL-17/IL-23 axis is relevant in IbD pathogenesis both in human and experimental studies. Novel biomarkers of IbD could be calprotectin,microRNAs, and serum proinflammatory *** efficient strategy for IbD therapy is represented by the combination of IL-17 A and IL-17 F in acute IL-17 A knockout TNbS-induced colitis, and also definite decrease of the inflammatory process in IL-17 F knockout, DSS-induced colitis have been *** the correlation between innate and adaptive immune systems, we hope to obtain a focused reviewin order to facilitate future approaches aimed at elucidating the immunological mechanisms that control gut inflammation.
