Proliferative vitreoretinopathy.
PURPOSE. The migration, proliferation, differentiation, and adhesion of cells and other cellular functions are influenced by the surrounding extracellular matrix, in normal and wound-healing conditions. The matrix metalloproteinases (MMPs) are a family of enzymes that degrade and remodel the extracellular matrix and, thus, play a central role in the wound-healing process. Proliferative vitreore...
متن کاملAnode break excitation in single myelinated nerve fibres.
It has long been considered that anode break excitation (ABE) is not elicitable in normal isolated nerve fibres. Quite recently, one of the authors (Konishi, 1957) found that it was due to weakness of the current applied and that, if a strong current (more than ten times the rheobase) was used, a single fibre, too, gave readily ABE. The present paper deals chiefly with threshold conditions for ...
متن کاملOn the capacity current in myelinated nerve fibres.
Different equivalent circuits are presented to describe the capacity current, Ic, of potential-clamped Ranvier nodes. The corresponding transfer functions are discussed in examining the influence of the involved parameters on size and time course of Ic. The following results were obtained: i. The duration and the amplitude of Ic increased with increasing membrane capacity. ii. The amplitude of ...
متن کاملFamilial exudative vitreoretinopathy associated with familial thrombocytopathy.
Two families with familial exudative vitreoretinopathy were studied in which platelet aggregation defects were found in all the affected members. The major defect observed was absent platelet aggregation with arachidonic acid. In addition platelet aggregation with collagen and adrenaline was reduced in one severely affected member. The implication of the platelet aggregation defect in the patho...
متن کاملApoptosis in proliferative vitreoretinopathy.
PURPOSE To study the involvement of apoptosis using different apoptosis markers in PVR pathogenesis. METHODS The presence of mRNA coding for Fas, Fas ligand (FasL), and TNF-related apoptosis inducing ligand (TRAIL) was investigated in vitreous samples from 46 consecutive patients-25 with PVR, 11 with retinal detachment (RD) not complicated by PVR, and 10 with macular hole (MH)-using RT-PCR. F...
