Verteporfin (VP), a benzoporphyrin derivative, is clinically used in photodynamic therapy for neovascular macular degeneration. Recent studies indicate that VP may inhibit growth of hepatoma cells without photoactivation through inhibition of YAP-TEAD complex. In this study, we examined the effects of VP without light activation on human retinoblastoma cell(More)
C-C chemokine receptor 2 (Ccr2) is a key pro-inflammatory marker of classic (M1) macrophage activation. Although Ccr2 is known to be expressed both constitutively and inductively, the full regulatory mechanism of its expression remains unclear. AMP-activated protein kinase (AMPK) is not only a master regulator of energy homeostasis but also a central(More)
Mullerian Inhibiting Substance (MIS) has been shown to inhibit ovarian cancer cells both in-vitro and in-vivo. Furthermore, recent evidence suggests that MIS may effectively target a putative ovarian cancer progenitor cell population enriched by a panel of CD44+, CD24+, Ep-CAM+, and E-cadherin-cell surface markers. In order to accommodate clinical testing(More)
The OCT angiograms showed reduced CNV flow area and CNV vessel loss following treatment. Because retinal vessel density did not decrease, reduced areas of CNV flow likely represent therapeutic effect. Optical coherence tomographic angiography can also be used to evaluate blood flow of the choriocapillaris. In healthy eyes, the choriocapillaris appears(More)
BACKGROUND Glaucoma is one of the leading largely preventable causes of blindness in the world. It usually is addressed first medically with topical intraocular pressure-lowering drops or by laser trabeculoplasty. In cases where such treatment fails, glaucoma-filtering surgery is considered, most commonly trabeculectomy surgery with variations in technique,(More)
Verteporfin (VP) was first used in Photodynamic therapy, where a non-thermal laser light (689 nm) in the presence of oxygen activates the drug to produce highly reactive oxygen radicals, resulting in local cell and tissue damage. However, it has also been shown that Verteporfin can have non-photoactivated effects such as interference with the YAP-TEAD(More)
Phagocytosis of daily shed photoreceptor outer segments is an important function of the retinal pigment epithelium (RPE) and it is essential for retinal homeostasis. RPE dysfunction, especially impairment of its phagocytic ability, plays an essential role in the pathogenesis of age-related macular degeneration (AMD). Statins, or HMG CoA(More)
The reappearance of polio in Syria in mid-2013, 18 years after it was eliminated from the country, manifests the public health catastrophe brought on by the civil war. Among the lessons learned, this outbreak emphasizes the importance of increasing the international financial and logistical support for vaccine and immunization efforts, especially in(More)
PURPOSE A group of Arab-American physicians and researchers in the United States organized a blended online course in academic writing and publishing in medicine targeting medical students and physicians in war-torn Syria. This was an effort to address one of the reasons behind the poor quantity and quality of scientific research papers in Syria and the(More)
