Introduction: Metalloproteinases and their tissue inhibitors play an important role in the metastases formation. A multistage process of carcinogenesis requires the involvement of numerous enzymes and compounds that facilitate the expansion of tumor cells. The formation of metastases depends on both metalloproteinases and tissue inhibitors activation leading to the acti...

Descemet's Membrane Endothelial Keratoplasty (DMEK) is a form of corneal transplantation in which only a single cell layer, the corneal endothelium, along with its basement membrane (Descemet's membrane) is introduced onto the recipient's posterior stroma(3). Unlike Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK), where additional donor stroma is introduced, no unnatural stroma-...

Cyclic phosphorylation and latent ATPase follow the distribution of photosystem I in the chloroplast membrane. Both activities are found higher in stroma lamellae than in grana. The extent of proton uptake is found to be higher in the grana. Since this uptake depends on internal volume and buffer capacity besides proton pump activity, the distribution of the proton pump proper remains to be elu...

BACKGROUND To present an intraoperative acute Descemet's fold formation using swept-source optical coherence tomography (SS-OCT) imaging. CASE REPORT A 67-year-old man complaining of reduced visual acuity in the left eye. A 25-gauge pars plana vitrectomy combined with phacoemulsification cataract surgery was performed to remove the vitreomacular traction. When hydro-sealing was performed, str...

nowadays, soil reinforcement using polymer elements have been investigated by a number of researchers in order to increase the load capacity of soils. reinforcing soils using fibers is a method of soil improvement, which offers a homogenous mixture in combination with soils, regarding their tensile strength. this combination maintains pressure loading capacity and properties in mutual resistant...

The development of the cornea as a tissue initiates as early as five weeks in the human embryo. This development continues gradually until the time of eyelid opening, which is associated with major developmental changes. These events, most easily observed in rodents, which are born with closed eyelids, include alterations in the rate of cell proliferation in the epithelium, stroma and endotheli...
