Identification of the Oligocene to early Miocene loricariid catfish †Taubateia paraiba as a member of the Rhinelepinae: List of taxa for which comparative CT-data were examined
<p>One of the earliest and most complete loricariid fossils is<i> †Taubateia paraiba, </i>which was described by Malabarba and Lundberg (2007) from southeastern Brazil based on a ventral impression of a neurocranium and some vertebrae. The fossil is from lacustrine habitat of the Tremembé Formation of the Taubaté Group, which is dated to the Oligocene to Early Miocene (~30–20 Mya). The locality (22°50' S, 45°52' W) is currently part of the Paraná River basin. Based on an extensive database of measurements of loricariids by the authors, the 54.5 mm long skull, equates to approximately 70 mm head length (snout to tip of supraoccipital), indicating a specimen that is ~175–210 mm long, which is fairly large for loricariids. In the original description, Malabarba and Lundberg described the anatomy of the fossil in detail, but they were unable to resolve the identity of the fish beyond its placement within Loricariidae.</p>

CT slices of three Protoceratopsian skulls and example slices of other Gobi Desert vertebrates
<p>This is a image dataset for deep learning studies. The main dataset comprises labeled CT slices from 3 protoceratopsian dinosaur skulls discovered from the Gobi Desert, Mongolia. The fossil specimens are now in the Division of Paleontology, American Museum of Natural History, New York, NY, USA. Inside the folders named after specimen number (i.e. IGM100-1021), there are six sub-folders comprising labeled or unlabled CT slice images of the specimen from three directions: axial, coronal, and sagittal. Each direction should contain all the information to reconstruct the entire specimen.</p> <p>The other folder named Gobi Vert comprise CT slices, but not enough to reconstruct the original specimens, of multiple vertebrate fossils also discovered from the Gobi Desert, Mongolia. The specimen number and taxa are noted in the image names.</p>
Data from: Efficacy and safety of CT-guided percutaneous fine needle aspiration and biopsy for malignant pulmonary lesions
<p>Background: CT guided percutaneous transthoracic fine needle aspiration (FNA) and core biopsy (CB) are commonly used to characterise lung lesions. There is conflicting information on which method is superior and wide variation in reported complication rates.</p> <p>Objectives: Our objectives were to establish the efficacy and safety of percutaneous CT guided FNA and CB in the diagnosis of malignant lung lesions.</p> <p>Methods: This retrospective study included patients who underwent CT guided percutaneous FNA and/or CB for lung parenchymal lesions at Kasturba Medical College Mangalore from January 2013 to December 2020. Ethical clearance was obtained from the Institutional Ethics Committee. Efficacy was determined by the adequacy of samples, sensitivity, specificity and diagnostic accuracy. Safety was assessed using the incidence of complications.</p> <p>Results: 326 patients underwent both FNA and CB, and 49 underwent FNA alone. Adequate samples were obtained in 82.9% of FNA cases and 95.7% of CB cases. Considering biopsy as the gold standard, the sensitivity, specificity and diagnostic accuracy of FNA for malignancy were 95.19%, 80% and 91.27%, respectively. Kappa agreement between the two methods was substantial (0.767). Pneumothorax was the only complication observed, and was seen in 31 patients (8.2%), of which only one required chest tube drainage. The incidence of pneumothorax was significantly higher in patients with pre-existing lung disease such as COPD/emphysema (p value 0.000), patients with smaller lesions (p = 0.009), and deeper lesions from the pleura (<span>p <0.0001)</span>.</p> <p>Conclusions: FNA and CB are both safe and effective procedures. In the absence of an onsite cytopathologist, we recommend a combination of both techniques.</p>
