End-to-End Automatic Classification of Retinal Vessel Based on Generative Adversarial Networks with Improved U-Net.

The retinal vessels in the human body are the only ones that can be observed directly by non-invasive imaging techniques. Retinal vessel morphology and structure are the important objects of concern for physicians in the early diagnosis and treatment of related diseases. The classification of retinal vessels has important guiding significance in the basic stage of diagnostic treatment.

Mouse mesenchymal stem cell-derived exosomal miR-466f-3p reverses EMT process through inhibiting AKT/GSK3β pathway via c-MET in radiation-induced lung injury.

Background: Radiation-induced lung fibrosis (RILF) is a common complication of thoracic radiotherapy. Alveolar epithelial cells play a crucial role in lung fibrosis via epithelial-mesenchymal transition (EMT). Exosomes derived from mesenchymal stem cells own the beneficial properties to repair and regeneration of damaged tissues, however the underlying mechanisms remain poorly understood.

[Association between murine double minute 2 expression and AngII and ceramide induced endothelial cells apoptosis].

Objective: To observe the relationship between murine double minute 2 (mdm2) expression and AngII and ceramide induced human umbilical endothelial cells apoptosis.

Method: Human umbilical endothelial cells (ECs) were cultured in vitro and treated with angiotensin II alone or in combination with losartan (an inhibitor of AT1), PD123319 (an inhibitor of AT2) and FB1 (an inhibitor of ceramidase) respectively. ECs were also treated with different doses of C2-ceramide.
