Abstract
Correct catheter position is crucial to ensuring appropriate function of the catheter and avoid complications. This paper describes a dataset consisting of 50,612 image level and 17,999 manually labelled annotations from 30,083 chest radiographs from the publicly available NIH ChestXRay14 dataset with manually annotated and segmented endotracheal tubes (ETT), nasoenteric tubes (NET) and central venous catheters (CVCs).

Abstract
BACKGROUND/AIMS Robinow syndrome is caused by mutations in Wnt-5a or its receptor Ror2 and can lead to cryptorchidism, though the mechanisms are unclear. Wnt-5a knock-out mice fail to undergo gubernacular swelling, similar to insulin-like hormone 3 (INSl-3) knock-out mice. We aimed to characterise Wnt-5a and Ror2 expression in rat gubernacula to better understand how Wnt-5a signalling affects testicular descent. METHODS Sprague-Dawley rats (n = 27) were collected with ethics approval (A644) at embryonic days (E) 15, 17, 19 and postnatal day (D) 2. Control and antiandrogen-treated groups were processed for immunohistochemistry for Wnt-5a, Ror2 and β-catenin. Sagittal sections were examined using confocal microscopy. RESULTS Wnt-5a and Ror2 were strongly expressed in the gubernacular bulb at E17 controls, their levels declining at E19 and almost absent by D2. Wnt-5a significantly co-localised with the important transcription factor β-catenin at E17. There was no obvious difference in staining with androgen blockade. CONCLUSION Wnt-5a, through Ror2 and β-catenin may play a vital role in regulating the gubernacular swelling reaction downstream of INSL-3. Human mutations in Wnt-5a or Ror2 could prevent early gubernacular growth, as suggested by undescended testes in 70% of patients with Robinow Syndrome.

Abstract
BACKGROUND/AIMS How androgens control inguinoscrotal descent remains controversial but may include canonical Wnt signaling via the transcriptional co-activator β-catenin. The canonical Wnt pathway transcribes genes regulating mesenchymal cell migration, fate, extracellular matrix remodeling, and in addition Axin2, a feedback product that reliably identifies Wnt activation. The relationship between β-catenin and androgen receptor warranted investigation into the involvement of the canonical Wnt pathway in testicular descent. METHODS Gubernacula from male Sprague-Dawley control (n = 22) and flutamide-treated (n = 18) rats at E17, E19, and D0 time-points were processed for immunohistochemistry. Sagittal sections stained for presence of androgen receptor, Axin2, and β-catenin were analyzed by fluorescent confocal microscopy. RESULTS At E19, β-catenin was strongly expressed in the membrane of developing cremaster muscle cells and the cytoplasm of gubernacular core cells. Axin2 expression was ubiquitous in nuclei of gubernacular mesenchymal cells, representing canonical Wnt signaling. After androgen blockade, Axin2 was conspicuously absent in the fibroblasts of the gubernacular core while remaining unaffected elsewhere. Reduced staining of Axin2 in E17 and D0 gubernacula suggests that Wnt signaling coincides with androgen programming. CONCLUSION Axin2 expression in the E19 gubernaculum confirms canonical Wnt pathway activation. Its absence in the core of flutamide-treated gubernacula indicates Wnt down-regulation. As androgen is required for inguinoscrotal descent, downstream Wnt signaling may control initial gubernacular remodeling. Defects in this complex molecular process may play a role in cryptorchidism.
