Revisiting diaphragmatic hernia of Joseon period Korean mummy by three-dimensional liver and heart segmentation and model reconstruction.

A three-dimensional (3D) segmentation and model reconstruction is a specialized tool to reveal spatial interrelationship between multiple internal organs by generating images without overlapping structures. This technique can also be applicable to mummy studies, but related reports have so far been very rare. In this study, we applied 3D segmentation and model reconstruction to computed tomography images of a Korean mummy with congenital diaphragmatic hernia.

A portrait drawing of the 17th century Korean scholar based on craniofacial reconstruction.

As a technique mainly hiring in forensic investigation field to identify the descents, craniofacial reconstruction (CFR) is also used in archaeology to create the faces from ancient or medieval human remains, when there is little information about his/her appearance. Eung-Cheok Ko (1531-1605) was a writer and scholar in the mid Joseon period. In January of 2019, His mummified body was found at Gumi, Kyeonsangbuk-do, Korea.

Expression of insulin-like growth factor-1 receptor in conventional cutaneous squamous cell carcinoma with different histological grades of differentiation.

Background: Insulin-like growth factor-1 receptor (IGF-1R) is a key regulator of cell transformation and controls the expression of genes that governs cell cycling and cell survival. The aim of this pilot study was to gain insight into the expression pattern of IGF-1R in conventional cutaneous squamous cell carcinoma (CSCC) using immunohistochemical analysis.

Materials And Methods: Five cases of normal human paraffin-embedded skin sections, 4 cases of actinic keratosis, and 28 cases of paraffin-embedded sections of different histological subtypes of CSCC were selected for immunohistochemical analysis.
