The pluripotency transcription factor Nanog represses glutathione reductase gene expression in mouse embryonic stem cells

Abstract Objective Redox homeostasis maintenance is essential to bring about cellular functions.Particularly, embryonic stem cells (ESCs) have high fidelity mechanisms for DNA repair, high activity of different antioxidant enzymes and low levels of oxidative stress.Although the expression and activity of antioxidant enzymes are reduced throughout t

Research on entropy weight variation evaluation method for wind power clusters based on dynamic layered sorting

This paper presents an evaluation method for the entropy-weighting of wind power clusters that comprehensively evaluates the allocation problems of wind power clusters by considering the correlation between indicators and the dynamic performance of weight changes.A dynamic layered sorting allocation method is also proposed.The proposed evaluation m
