Littoral cell angioma is a splenic vascular tumor of splenic sinus lining cells that is considered benign in general. This report describes a case of littoral cell angioma with no malignant histological features. The lesion is composed of anastomosing vascular channels resembling splenic sinus; they are lined by endothelial cells which show mitotic activity very rare. Immunohistochemically, ...

PURPOSE To compare the extent of corneal endothelial (CE) cell loss changes in two groups of eyes submitted to phacoemulsification, with the conventional bevel-up tip position in one eye and with the bevel-down tip position in the fellow eye. METHODS This prospective clinical trial comprised 25 patients with bilateral cataracts subjected to lens removal by phacoemulsification with the convent...

Objective: Envenomation by heamotoxic snakes constituted a critical health occurrence in the world. Bleeding is the most sever consequence following snake bite with viperid and crothalid snakes. It is believed that the degradation of vascular membrane caused hemorrhage; in contrast, some suggested that direct cytotoxicity has role in endothelial cell disturbances. This study was to evaluate the...

Purpose Iridocorneal endothelial (ICE) syndrome is a progressive anterior segment disorder that can be tricky to treat. Keratoplasty commonly used treat corneal edema in ICE syndrome. However, glaucoma an important risk factor affecting graft survival. To address this question, we designed retrospective cohort study evaluate the effect of Spokewise Iridotomy (SI) on Descemet Stripping Automated...

Angiogenesis is in part related to mast cells. However, the biological significance of mast cells within lung carcinoma remains unclear. Immunohistochemistry was used to stain for tryptase, CD34 and vascular endothelial growth factor (VEGF) in 85 cases of stage I nonsmall cell lung carcinoma. VEGF was found in 33 of 53 adenocarcinomas and 14 of 32 squamous cell carcinomas. Cases of adenocarcino...

The loss of the corneal endothelial cells, especially in a first postoperative year, has been observed in patients who underwent penetrating keratoplasty (PK). The implantation of new generation of "iris claw" phakic IOL (Verisyse) in refractive cases has been shown to cause clinicaly insignificant endothelial cell loss. In our prospective case series we investigated the endothelial cell loss a...

diabetic retinopathy is the lead among causes of blindness in north america. glucose-induced endothelial injury is the most important cause of diabetic retinopathy and other vascular complications. extracellular signal-regulated kinase 5 (erk5), also known as big mitogen-activated protein kinase 1 (bmk1), is a member of mitogen-activated protein kinases (mapk) family. physiologically, it is cri...
