The results demonstrate that BRUV was more efficient at surveying the entire fish community, specifically invertebrate carnivores, generalist carnivores and cartilaginous species. On the other hand, RUV was more effective at surveying microinvertebrate carnivores. High variability Citarinostat in vivo in the RUV data resulted in the method requiring a greater number of samples to achieve the same diagnostic power as BRUV. However, RUV required a shorter deployment and post-sampling video analysis time, making it more time efficient. Baited remote underwater video was more sensitive in the detection of differences in abundance between habitat

types, while the RUV data were more prone to an intra-species methodological bias linked to the percentage of reef visible in the frame of view. The scale of the response to the presence of bait was inconsistent among species, indicating that behaviour determined the area selleck compound surveyed within the bait plume of BRUV. The benefits gained by sampling the fish community with RUV do not outweigh those obtained by altering the community through the presence of bait. However, in combination, the 2 methods are highly effective at monitoring the

subtidal fish communities in the Agulhas bioregion of South Africa.”
“BACKGROUND: Invasive pancreatic carcinoma generally appears as poorly defined mass reflecting the infiltrative growth. We aimed to identify the histological and immunohistochemical features in a rare case of pancreatic carcinoma showing exophytic growth.\n\nMETHODS: A 67-year-old woman presented with a mass of 5.0 cm in diameter in the pancreatic head. Preoperative computed tomography revealed a well-demarcated, primarily solid mass with a central low-density area. Magnetic resonance cholangiopancreatography revealed neither encasement nor dilation of the main

pancreatic selleckchem duct. An incorrect preoperative diagnosis was made of solid pseudopapillary tumor of the pancreas. Elevated serum carcinoembryonic antigen (CEA) levels and abnormal FDG positron emmission tomography accumulation suggested that the tumor had malignant potential requiring a pancreatoduodenectomy.\n\nRESULTS: The head of the pancreas contained a well-circumscribed encapsulated mass of 5.0 cm in diameter, comprising 50% adenocarcinoma, with mucinous carcinoma in the center and anaplastic carcinoma at the periphery. The anaplastic carcinoma comprised pleomorphic cells (PCs) and pleomorphic giant cells (PGCs). The PGCs phagocytozed mononuclear PCs and lymphocytes adjacent to the capsule without infiltrating the capsule itself. Immunohistochemistry revealed that the anaplastic carcinoma cells including PGCs were positive for the tumor antigen Mucin 1 and CEA but negative for vimentin.
