    February 6, 6pm Location: Payne Room Free and open to the public. In conjunction with the exhibition This Place Part of the Palestinian Voices series, organized and co-sponsored by the John B. Moore Documentary Studies Collaborative (MDOCS), the Environmental Studies and Sciences Program, International Affairs, Media and Film Studies, Art History, History, Hayat, and the Skidmore College Dean’s Office Join us for a lecture by Issam Nassar on the history of Palestinian photography. Nassar is a historian of the Modern Middle East and of Photography at Illinois State University. His work focuses on the modern Middle East and the history of photography. He is the co-editor of Jerusalem Quarterly and the author and editor of a number of books, including the editor of I Would Have Smiled: Photographing the Palestinian Refugee Experience (Institute for Palestinian Studies, 2009) with Rashā Salṭī, and The Story of Jerusalem (Olive Branch Press, 2013). Murat Yildiz, Assistant Professor of History at Skidmore College, will introduce Nassar and moderate a discussion following the talk. This talk is part of exhibition This Place, on view February 3 through April 22, 2018, as well the Palestinian Voices series. The Palestinian Voices series is organized and co-sponsored by the John B. Moore Documentary Studies Collaborative (MDOCS), the Environmental Studies and Sciences Program, International Affairs, Media and Film Studies, Art History, History, Hayat, and the Skidmore College Dean’s Office. This event is free and open to the public

    The short-term effect of atorvastatin on carotid plaque morphology assessed by computer-assisted gray-scale densitometry: a pilot study

    Soft, lipid-containing carotid plaques, which appear echolucent on ultrasound imaging, have been associated with increased risk of ischemic stroke. We sought to investigate the effect of short-term treatment with atorvastatin on the change of carotid plaque echodensity. We treated 40 stroke-free and statin-naive subjects with 80 mg atorvastatin daily for 30 days. Computer assisted gray-scale densitometry (GSD) index was calculated at baseline and 30 days after treatment from the normalized plaque images. A multiple logistic regression was used to assess the effect modification of low-density lipoprotein (LDL) cholesterol on plaque stabilization after adjusting for age, sex, and smoking. The average number of carotid plaques at baseline was 2 (range: 0-5; 27 subjects with carotid plaque) and did not change 30 days following atorvastatin treatment. The mean GSD index significantly increased from 73 +/- 16 (range: 1-125) at baseline to 89 +/- 15 (range: 1-137) at 30 days after treatment (P<0.05). The adjusted odds ratio for the positive GSD plaque index change (vs. no change or decreased gray-scale median (GSM) index) was 1.71 (95% confidence interval: 1.1-7.6, P<0.01). In conclusion, we observed decreased echolucency (increased echodensity) of carotid artery plaques after short-term treatment with atorvastatin

    Risk stratification of patients with asymptomatic carotid artery stenosis: evaluation of carotid stenosis severity, progression, and morphology by duplex ultrasound

    The evaluation of patients harboring significant carotid atherosclerotic disease entails a careful evaluation of the likely mechanism(s) leading to the increased risk of future stroke. This will facilitate clinical decision-making in terms of triaging patients to medical therapy alone vs medical therapy and carotid revascularization

    Cerebrovascular anatomy and physiology and mechanisms of first-ever ischemic stroke in patients with carotid artery stenosis

    Fundamental to caring for patients with carotid artery disease is a basic understanding of cerebrovascular anatomy and physiology as well as knowledge of the mechanisms and patterns of ischemic stroke in these patients. The brain is a highly metabolic organ, utilizing 20% of the body’s energy at rest with limited metabolic substrate reserve. This limited anaerobic capacity makes the brain intrinsically dependent upon a continuous supply of blood to meet its energy demands. The unique anatomy of the cerebrovascular system allows for instantaneous, dynamic regulation of flow through collateralization from multiple inputs and connections. Blood will always flow from an area of high pressure into an area of a lower pressure, so that alterations in the vascular structure may alter which cerebral territories are at greatest risk by altering the pressure gradient. The healthy cerebrovascular system has developed mechanisms to compensate for external stressors that may limit the central nervous system (CNS) energy delivery or utilization. In disease, these mechanisms may be maximally stressed so that the introduction of another stressor may lead to vascular inefficiency and subsequent brain ischemia
