Fecal samples obtained from 600 household cats (244 males and 356 females) kept in 3 prefectures of Tohoku district in Japan were examined for Giardia intestinalis antigen, using a commercial enzyme-linked immunosorbent assay (ELISA) kit. G. intestinalis antigen was detected in 40% of the fecal specimens. The factors such as the age, life style or environmental condition of cats could be signif...
Macroalgal blooms have contributed to declines in foundation species such as corals and seagrasses across the globe. Most studies of macroalgal bloom effects on seagrasses focus on the short-term effects, and have been conducted in locations that already begun the shift to macroalgal dominance, usually due to eutrophication. Our goal was to determine the degree to which the timing and magnitude...
Evidence of an inorganic carbon concentrating system in a marine macroalga is provided here. Based on an O(2) technique, supported by determinations of inorganic carbon concentrations, of experimental media (as well as compensation points) using infrared gas analysis, it was found that Ulva fasciata maintained intracellular inorganic carbon levels of 2.3 to 6.0 millimolar at bulk medium concent...
The stoichiometry and antenna sizes of the two photosystems in two marine green algae, Bryopsis maxima and Ulva pertusa, were investigated to examine whether the photosynthetic apparatus of the algae can be related to the light environment of their natural habitat. Bryopsis maxima and Ulva pertusa had chlorophyll (Chl) a/b ratios of 1.5 and 1.8, respectively, indicating large levels of Chl b, w...
Fanconi anemia (FA) is a human genetic disease characterized by congenital defects, bone marrow failure, and increased cancer risk. FA is associated with mutation in one of 24 genes. The protein products of these genes function cooperatively in the FA pathway to orchestrate the repair of DNA interstrand cross-links. Few model organisms exist for the study of FA. Seeking a model organism with a ...
Encephalitozoon intestinalis (Septata intestinalis) is the second most prevalent microsporidian species infecting humans, but it has not been described in other animal species. This investigation examined 10 domestic animal stool samples (8 mammalian, 2 avian) containing spores detected by anti-Encephalitozoon monoclonal antibody immunofluorescence (FA). The presence of E. intestinalis but not ...
Pneumatosis intestinalis is defined as the presence of gas within the wall of the gastrointestinal tract. Originally described on plain abdominal radiographs, it is an imaging sign rather than a specific diagnosis and it is associated with both benign and life-threatening clinical conditions. The most common life-threatening cause of pneumatosis intestinalis is bowel ischaemia. Computed tomogra...
Pneumatosis intestinalis, defined as gas in the bowel wall, is often first identified on abdominal radiographs or computed tomography (CT) scans. It is a radiographic finding and not a diagnosis, as the etiology varies from benign conditions to fulminant gastrointestinal disease. We report here a case of pneumatosis intestinalis associated with cetuximab therapy for squamous cell carcinoma of h...
Through the fixation of large quantities dissolved inorganic carbon (DIC), macroalgae facilitate energetic foundation highly productive coastal ecosystems. While processes controlling photosynthesis and by are well known, fate organic matter fixed is less understood. This study quantified release rates DOC three ecologically significant Baltic species: perennial habitat forming Fucus vesiculosu...
Ulva taeniata contains oxidase. The existence of peroxidase is not proved.
