The value of seasonal energy storage depends on how the firm best operates the storage to capture the seasonal price spread. Energy storage operations typically face limited operational flexibility characterized by the speed of storing and releasing energy. A widely used practice-based heuristic, the rolling intrinsic (RI) policy, generally performs well,(More)
Purpose The pathological mechanisms underlying cataract formation remain largely unknown on account of the lack of appropriate in vitro cellular models. The aim of this study is to develop a stable in vitro system for human lens regeneration using pluripotent stem cells. Methods Isolated human urinary cells were infected with four Yamanaka factors to(More)
Purpose. It has been confirmed that inflammatory cytokines are involved in the progression of pterygium. Histamine can enhance proliferation and migration of many cells. Therefore, we intend to investigate the proliferative and migratory effects of histamine on primary culture of human pterygium fibroblasts (HPFs). Methods. Pterygium and conjunctiva samples(More)
The aging of lens progenitor cell has been repeatedly proposed to play a key role in age-related cataracts (ARCs), but the mechanism is far from being understood. The present study aims to investigate the relationship between aging of lens progenitor/epithelial cells and the 4 subtypes of ARCs in humans.Lens capsules, which were collected from ARC patients(More)
The scarcity of corneal tissue to treat deep corneal defects and corneal perforations remains a challenge. Currently, small incision lenticule extraction (SMILE)-derived lenticules appear to be a promising alternative for the treatment of these conditions. However, the thickness and toughness of a single piece of lenticule are limited. To overcome these(More)
OBJECTIVE Analyze the factors affecting postoperative outcomes in patients with solid cerebellar hemangioblastomas. PATIENTS AND METHODS We retrospectively analyzed the clinical data of 22 patients with sporadic solid cerebellar hemangioblastomas. Data regarding the clinical materials and imaging features, diameter of the lesion, operative approaches and(More)
Microglial activation plays a crucial role in the pathological processes of various retinal and optic nerve diseases. TNF-α is a pro-inflammatory cytokine that is rapidly upregulated and promotes retinal ganglion cells (RGCs) death after optic nerve injury. However, the cellular source of TNF-α after optic nerve injury remains unclear. Thus, we aimed to(More)
