Programmed cell death (PCD) is a major mechanism for patterning of a variety of complex structures. Cells are initially organized into fairly loose patterns; then, selective death removes the cells between pattern elements to create the correct structures, as a sculptor removes some material to reveal the hidden image. The life or death of a cell is mostly(More)
PURPOSE To evaluate the efficacy of surgical treatment for conjunctivochalasis by monitoring matrix metalloproteinase (MMP)-9 levels in the tears of patients with conjunctivochalasis before and after surgery and their correlation with clinical signs and symptoms. METHODS Twelve eyes of patients with symptomatic conjunctivochalasis were included in this(More)
PURPOSE The etiology of keratoconus (KC) and the factors governing its progression are not well understood. It has been suggested that this disease might be caused by biochemical alterations in the cornea; changes in the expression profiles of human aqueous humor (hAH) proteins have been observed in some diseases. To gain a new insight into the molecular(More)
PURPOSE To investigate the effect of poly (lactic-co-glycolic acid) (PLGA) implants loaded with mitomycin C (MMC) and with different adjuvant treatments after glaucoma filtration surgery (GFS), in comparison to standard treatments. METHODS Forty-two New Zealand White rabbits underwent bilateral GFS and received different treatments: topical MMC (group 1);(More)
PURPOSE To evaluate the sensitivity and specificity of a PCR-strip system based on reverse dot blot for detection of MUC5AC mRNA in corneal epithelium samples from patients with limbal stem cell deficiency (LSCD), and to determine the correlation with clinical diagnosis. METHODS We obtained 87 corneal impression cytology (IC) samples from 55 subjects (37(More)
