Flavonoids, the major polyphenol components in Cotinus coggygria (CC), have been found to show an anticancer effect in our previous study; however, the exact mechanisms of inducing human glioblastoma (GBM) cell death remain to be resolved. In this study, a novel polyvinylpyrrolidone K-30/sodium dodecyl sulfate and polyethyleneglycol-coated liposome loaded with CC flavonoids (CCFs) was developed...

Classical distribution testing assumes access to i.i.d. samples from the distribution that is being tested. We initiate the study of Markov chain testing, assuming access to a single trajectory of a Markov Chain. In particular, we observe a single trajectory X0, . . . , Xt, . . . of an unknown, symmetric, and finite state Markov ChainM. We do not control the starting state X0, and we cannot res...

Coronary-cameral fistula (CCF) is an anomalous connection between a coronary artery and cardiac chamber. Most of CCFs are discovered incidentally during angiographic evaluation for coronary vascular disorder. We report a case of CCF with angina pectoris. Selective coronary arteriography revealed diffuse CCF involving the left anterior descending artery (LAD) emptying into left ventricle (LV) an...

Direct exposure and cannulation of the superior ophthalmic vein (SOV) provides an alternative access to reach the cavernous sinus for carotid-cavernous fistula (CCF) embolization, when classic transvenous routes through the inferior petrosal sinus (IPS) or facial vein are not feasible. We have used indocyanine green (ICG)-videoangiography to study intraoperatively the flow inside the SOV in two...

In dictionary learning, also known as sparse coding, we are given samples of the form y = Ax where x ∈ R is an unknown random sparse vector and A is an unknown dictionary matrix in Rn×m (usually m > n, which is the overcomplete case). The goal is to learn A and x. This problem has been studied in neuroscience, machine learning, vision, and image processing. In practice it is solved by heuristic...

PURPOSE To study the frequency of ocular manifestations and the prognosis of secondary glaucoma in cases of carotid-cavernous fistula (CCF). METHODS A retrospective multicenter study was conducted to investigate causes, types, ocular symptoms, complications, treatment, and prognosis in subjects with CCF. RESULTS Among the 43 patients diagnosed with CCF between 1984 and 2000, a total of 13 p...

Most symptoms and signs associated with a carotid cavernous fistula (CCF) are thought to be related to regurgitation of flow into cortical veins and to venous congestion. Arteriovenous shunting and secondary perfusion insufficiency is regarded as less important in causing symptoms. We describe a 27-yr-old male patient who had improvement of neurologic symptoms and signs after detachable balloon...

Intracavernous carotid artery aneurysms causing a carotid-cavernous fistula (CCF) are rare. These aneurysms usually cause neurological symptoms due to gradual expansion without rupture. If they do rupture they most often lead to a CCF instead of bleeding into the subarachnoid space. A patient is described with a ruptured intracavernous aneurysm causing a CCF resulting in acute onset of unilater...

After the spontaneous relief of initial symptoms by traumatic carotid-cavernous fistula (CCF), paradoxical worsening of patient's condition can be followed. We present a case of a 60-yr-old man whose audible bruit from a traumatic CCF had completely disappeared. A few days later, however, the patient had spontaneous intracerebral hematoma with cortical venous drainage. Complete obliteration of ...
