The diabetic population is increasing worldwide at a staggering rate. Diabetic foot ulcers are a major contributor to nontraumatic lower limb amputations and peripheral arterial disease is one of main contributing pathophysiologic causes of diabetic ulcers. The dire need to reduce complication and wound healing recovery period of the chronic ischemic(More)
OBJECTIVE Patients with Parkinson's disease (PD) have an increased risk of melanoma, although the mechanisms are unclear. We are unaware of studies that have assessed the association between other movement disorders, such as essential tremor (ET) and dystonia, and melanoma. In this study, we assessed the association between ET, PD, dystonia and cancer (esp.(More)
IMPORTANCE Abdominal aortic aneurysms are associated with chronic inflammation within the aortic wall, and previous studies have suggested that chronic inflammation may be a consequence of a dysregulated and persistent autoimmune response. Persistent aortic remodeling after aneurysm repair could place the patient at risk for endoleak or sac rupture. (More)
Extracellular signal-regulated kinase 5 (ERK5) has been reported to regulate endothelial cell integrity and protect from vascular dysfunction under continuous laminar flow. However, the effect of flow on ERK5 levels has not been determined. Confluent human umbilical vein endothelial cells (HUVECs) were seeded on fibronectin coated glass slides and serum(More)
BACKGROUND Public awareness of and attitude toward disease is an important issue for patients. Public awareness of essential tremor (ET) has never been studied. METHODS We administered a 10-min, 31-item questionnaire to 250 consecutive enrollees. These included three samples carefully chosen to have a potential range of awareness of ET: 100 individuals(More)
BACKGROUND Statins have potent anti-inflammatory and immunomodulating effects, and may have neuroprotective properties in patients with Parkinson's disease (PD). There are no studies about the use of statins in the related tremor disorder, essential tremor (ET). We determined whether statin use differed in ET cases vs. controls and PD cases vs. METHODS(More)
Yes-associated protein (YAP) is a mechanosignaling protein that relays mechanical information to the nucleus by changing its level of phosphorylation. We hypothesize that different flow patterns show differential effect on phosphorylated YAP (pYAP) (S127) and total YAP and could be responsible for flow dependent localization of atherosclerosis. Confluent(More)
African trypanosomes are tsetse fly transmitted protozoan parasites responsible for human African trypanosomiasis, a disease characterized by a plethora of neurological symptoms and death. How the parasites under microvascular shear stress (SS) flow conditions in the brain cross the blood-brain barrier (BBB) is not known. In vitro studies using static(More)
