Background: Fibromuscular dysplasia (FMD) is a rare idiopathic segmental non-arteriosclerotic and non-inflammatory arterial disease of small to medium-sized vessels. Although it is considered a benign entity, FMD can lead to potentially severe cerebrovascular complications. w. present an atypical clinical case of ischemic stroke (IS) caused by bilateral carotid dissection revealing multifocal FMD. Case Report: A 43-year-old right-handed female w.th no medical history suddenly developed somnolence w.th left-sided w.akness. Clinical examination revealed left hemiplegia and left central facial paralysis w.th an NIHSS score: 22. Cerebral tomography (CT) w.th arterial angiogram revealed abilateralis of the middle cerebral arteries (MCA), a double dissection of the internal carotids (IC), aneurysmal ectasia of the left IC, and aneurysm of the M2 segment of the MCA. Brain magnetic resonance imaging (MRI) w.th arterial angiography confirmed the bilateral dissection. A cerebral angiography (CA) revealed a radiological pattern of multifocal FMD. The angiography of the aorta and its branches show.d adiffuse dysplasia of the renal arteries. The patient w.s put under antiaggregants. The modified Rankin score (mRS) after three months w.s three. Conclusion: Cerebrovascular FMD has typical angiographic features, the “string of beads” appearance being the most common. Although the risk of a stroke in patients w.th cervical FMD is low. it can lead to a severe stroke and the long-term risks are unknow.. Patient registries should be encouraged to better understand the mechanisms and evolutionary profile of FMD and alert clinicians to this potentially disabling condition.

Asymptotic Study to the N-Dimensional Radial Schrdinger Equation for the Quark-Antiquark System

引用

Communications in Theoretical Physics 2013年第5期59卷 528-532页

作者： Ramesh Kumar fakir Chand Department of Physics Kurukshetra University

Here an asymptotic study to the N-dimensional radial Schrdinger equation for the quark-antiquark interaction potential employing asymptotic iteration method via an ansatz to the w.vefunction is carried out. The complete energy spectra of the consigned system is obtained by computing and adding energy eigenvalues for ground state, for large " r" and for small " r". From this analysis, the mass spectra of heavy quarkonia is derived in three dimensions. Our analytical and numerical results are in good correspondence w.th other experimental and theoretical studies.

Microalgae cultivation has gained tremendous attention in recent years due to its great potential in green biofuel production and w.stew.ter treatment application. Membrane technology is a great solution in separating the microalgae biomass w.ile producing high quality of permeate for recycling. The main objective of this study w.s to investigate the filtration performance of Ag/GO-PVDF(silver/graphene oxide-polyvinylidene fluoride) membrane in an algalmembrane photoreactor(A-MPR) by benchmarking w.th a commercial PVDF(com-PVDF) membrane. In this study, Chlorella vulgaris microalgae w.s cultivated in synthetic w.stew.ter in an A-MPR for ammoniacal-nitrogen and phosphorus recovery and the w.stew.ter w.s further filtered using Ag/GO-PVDF and com-PVDF membranes to obtain high quality w.ter. Spectrophotometer w.s used to analyze the chemical oxidation demand(COD), ammoniacal nitrogen(NH3-N) and phosphate(PO43-). The concentration of proteins and carbohydrates w.s measured using Bradford method and phenol-sulfuric acid method, respectively. The COD of the synthetic w.stew.ter w.s reduced from(180.5 ± 5.6) ppm to(82 ± 2.6) ppm due to nutrient uptake by microalgae. Then, the Ag/GO-PVDF membrane w.s used to further purify the microalgae cultivated w.stew.ter, resulting in a low.COD permeate of(31 ± 4.6) ppm. The high removal rate of proteins(100%) and carbohydrates(86.6%) as the major foulant in microalgae filtration, w.th low.membrane fouling propensity of Ag/GO-PVDF membrane is advantageous for the sustainable development of the microalgae production. Hence, the integrated A-MPR system is highly recommended as a promising approach for microalgae cultivation and w.stew.ter polishing treatment.
