Background: Alpha-1-antitrypsin is a protein involved in avoidance of different processes that are seen in diabetic retinopathy pathogenesis. These processes include apoptosis, extracellular matrix remodeling and damage of vessel walls and capillaries. Furthermore, because of its anti-inflammatory effects, alpha-1-antitrypsin has been proposed as a possible therapeutic approach for diabetic retinopathy.

Purpose: The objective is to analyze the antiangiogenic mechanism of suramab, a pharmaceutical compound of bevacizumab and suramin, in a rabbit model of corneal angiogenesis.

Material And Methods: Corneal neovascularization was induced in four groups of six New Zealand White rabbits by applying a filter paper disk soaked in 1 M Na (OH) on the central cornea. Group one was treated after injury with intravenous suramab at a dose equivalent to 3 mg/kg of bevacizumab and 10 mg/kg of suramin.

The association of cerebral ischemic attack with patent foramen ovale has not been extensively studied, and frequently the site of origin of embolism is not detected despite routine studies. We present the case of a young patient with ischemic stroke and permeable oval foramen in the context of May Thurner syndrome. The May Thurner syndrome is an entity scarcely studied in the medical literature and it has also been infrequently related to ischemic vascular cerebral accident, but in patients with permeable oval foramen without evidence of the emboligen source, it is interesting to rule it out as a cause of paradoxical embolism.

We aim to evaluate if the prevalence of vascular risk factors accounts for differences observed in stroke subtypes by race/ethnicity. Patients with acute stroke were prospectively enrolled in the Miami Stroke Registry.
