The recognition that the vascular endothelial growth factor (VEGF) pathway is a key regulator of angiogenesis has led to the development of several VEGF-targeted approaches. These include neutralizing antibodies, VEGF traps or selective tyrosine kinase inhibitors for VEGFRs. Other drugs that indirectly affect VEGF pathway, such as statins or arsenic trioxide, also have been shown to possess antiangiogenic buy BAY 57-1293 activity in leukemias. The benefits of these VEGF targeted agents and their current stage of development as novel anti-antiangiogenic
therapies in AML are discussed in this review. (C) 2010 Elsevier Ireland Ltd. All rights reserved.”
“Two cases of postoperative intraocular lens (IOL) calcification in patients implanted with the Akreos Adapt IOL at the time of combined phacovitrectomy are described, along with clinical
review of all patients implanted with this IOL type at our institution between November 2006 and September 2008. The IOLs explanted from the 2 cases were examined using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). The SEM of the explanted IOLs showed crystalline anterior surface and subsurface deposits; DZNeP solubility dmso by EDX, the deposits showed high concentrations of calcium and phosphorous, consistent with calcium apatite. Twenty patients (20 eyes) attended for cohort review, and none showed IOL opacification. The reason calcification occurred in the 2 cases remains unknown, but clinicians should be aware of this potential complication.”
“Background: Worldwide, cardiovascular (CV) disease remains the most common cause of morbidity and mortality. Although effective in predicting CV risk in select populations, the Framingham risk score (FRS) fails to identify many young Selleckchem AZD5363 individuals who experience premature CV events. Accordingly, the aim of this study was to determine the prevalence of high-risk carotid intima-media thickness (CIMT) or plaque, a marker of atherosclerosis
and predictor of CV events, in young asymptomatic individuals with low and intermediate FRS (<2% annualized event rate) using the carotid ultrasound protocol recommended by the American Society of Echocardiography and the Society of Vascular Medicine.\n\nMethods: Individuals aged <= 65 years not taking statins and without diabetes mellitus or histories of coronary artery disease underwent CIMT and plaque examination for primary prevention. Clinical variables including lipid values, family history of premature coronary artery disease, and FRS and subsequent pharmacotherapy recommendations were retrospectively collected for statistical analysis.\n\nResults: Of 441 subjects (mean age, 49.7 +/- 7.9 years), 184 (42%; 95% confidence interval, 37.3%-46.5%) had high-risk carotid ultrasound findings (CIMT >= 75th percentile adjusted for age, gender, and race or presence of plaque).
