Kölliker's organ is a transient developmental structure in the mouse cochlea that undergoes significant remodeling postnatally. Utilizing an epithelial-specific conditional deletion model of Prdm16 (marker and regulator organ), we show required for interdental cell development, thereby development limbal domain tectorial membrane its medial anchorage to spiral limbus. Additionally, involved normal collagen fibril maturation. Interestingly, mesenchymal cells limbus underneath -deficient...

408 Background: DPAI models have recently demonstrated the potential to improve risk stratification beyond routine clinical and pathologic variables. However, it is not known whether integrating information will enhance prognostic accuracy of validated gene expression tests. In this study, performance novel algorithms were assessed in context genomic classifier (GC). Methods: A prospectively collected cohort 9,874 patients with localized prostate cancer was retrieved from Veracyte GRID...

335 Background: Recent advances in AI have brought innovation to digital pathology problems with H&E whole slide images (WSI). Though some (DPAI) models been developed for survival analysis TCGA data, there is a lack of understanding as how DPAI predict progression free (PFS) the prostate dataset (PRAD). Nor comprehensive comparison versus genomic or clinical models. Batch effects were also ignored prior works. Methods: PRAD contains 392 patients WSI and data. batch effect was first...

Persistent corneal epithelial defects (PCEDs) are a challenging ocular condition characterized by the failure of complete healing after an insult or injury, even 14 days standard care. There is lack therapeutics that target this and encourage re-epithelialization surface in timely efficient manner. This review aims to provide overview current standards management for PCEDs, highlighting novel, emerging treatments field. While many non-surgical aim lubrication mechanical support, novel...

We sought to determine potential patient reported advantages of the da Vinci single-port (SP) robotic system for urological procedures compared with previous model, multiport (MP) system. The SP model utilizes a single 30 40 mm incision rather than multiple 5 22 incisions. This project aims prospectively investigate impact novel on cosmetic and psychometric surgical outcomes.
