(after 9 days PI), fibrinonecrotic enteritis further developed with increased mucosal necrosis and inflammatory exudation of the small intestine. Intestinal obstructions formed in the middle-lower part of small intestine, which was considered to be a typical pathological change associated with NGVE disease. None of the control goslings died, developed any clinical symptoms, or displayed any... In this study, apoptosis was induced by new type gosling viral enteritis virus (NGVEV) in experimentally infected goslings is reported in detail for the first time. After 3-day-old goslings were orally inoculated with a NGVEV- CN strain suspension, the time course of NGVEV effects on apoptotic morphological changes of the internal tissues was evaluated. These changes were observed by histological analysis with light microscopy and ultrastructural analysis with transmission electron microscopy.... -

abundant gum exudation have occurred on yuzu trees in Goheung-gun, Jeonnam Province, where se- verely affected trees were occasionally killed. On-farm surveys were conducted at 30 randomly-selected or- chards located at Pungyang-myeon, Goheung-gun, and the resulting disease incidences were 18.5% and 39.6% for dieback and gumming symptoms, respectively. Black spots on branches and leaves also... Starting in 2012, severe diebacks usually accompanied by abundant gum exudation have occurred on yuzu trees in Goheung-gun, Jeonnam Province, where severely affected trees were occasionally killed. On-farm surveys were conducted at 30 randomly-selected orchards located at Pungyang-myeon, Goheung-gun, and the resulting disease incidences were 18.5% and 39.6% for dieback and gumming symptoms, respectively. Black spots on branches and leaves also appeared on infected trees showing a typical dieback... -

Jones, 1976; Pegard and Brizzard, 2005; Tanda et al., 1989). In Phytophthora blight of chili pepper caused by Phytophthora capsici, the pathogen penetration and infection appear to be blocked by root exudation materials accumulated on the root surface and by thickened middle lamellae between the epidermal and cortical cells (Kim and Kim, 2009). In cv. Chilseongcho, extensive giant cells were form... Biological and structural mechanisms of the nematode disease development in chili pepper caused by the rootknot nematode, Meloidogyne incognita, were investigated. Out of 39 chili pepper cultivars/lines tested, six were found resistant, while 33 were susceptible to M. incognita, of which a susceptible cultivar Chilseongcho and three resistant cultivar/lines CM334, 02G132 and 03G53 with different resistance degrees were selected for microscopic studies on the disease development. Gall formation... -

et al. [8] reported the exudation of mesophase pitch, stabilized in air with an OMG as high as 5.8%, during car- bonization. The exudation of SP with an OMG as low as 0.8 % was not noted in our earlier study even under hot-pressing pres- difference is ascribed to different origins of the pitch based ma- trix precursor. Since the stabilization of the matrix precursor of the present study was... for a duration of 5 h could withstand almost two-fold greater hot-pressing pressure without resulting in exudation as compared to that of a 1 h stabilized matrix precursor. The enhanced hot-pressing pressure significantly improved the yield of the matrix precursor. As a consequence, the densification and mechanical properties were increased significantly. Further, the matrix precursor stabilized for a duration of 20 h or more failed to provide proper and uniform binding of the reinforcement. -
