Abstract Screen-printing provides an economically attractive means for making Ag electrical contacts to Si solar cells, but the use of substantiates a significant manufacturing cost, and glass frit used in paste enable contact formation contains Pb. To achieve optimal performance develop pastes with alternative, abundant non-toxic materials, better understanding process during firing is required. Here, we situ X-ray diffraction reveal reaction sequence. The findings suggest that between 500...
<h3>BACKGROUND AND PURPOSE:</h3> Treatment of patients with ischemic stroke after endovascular treatment requires in-depth knowledge complications. The goal this study was to make for acute safer through an review the major periprocedural complications observed in Solitaire FR With Intention Thrombectomy (SWIFT) trial. <h3>MATERIALS METHODS:</h3> SWIFT data base searched peri-procedural defined as symptomatic intracranial hemorrhage within 36 hours, SAH, air emboli, vessel dissection, groin...
Treatment outcome in congenital adrenal hyperplasia is often suboptimal due to hyperandrogenism, treatment-induced hypercortisolism, or both. We previously reported better control of linear growth, weight gain, and bone maturation a short term cross-over study new four-drug treatment regimen containing an antiandrogen (flutamide), inhibitor androgen estrogen conversion (testolactone), reduced hydrocortisone dose, fludrocortisone, compared the effects fludrocortisone. Twenty-eight children...
Children with classic congenital adrenal hyperplasia (CAH) have multiple endocrine imbalances, including prenatal glucocorticoid and adrenomedullary deficiency androgen excess, possible postnatal iatrogenic hyperandrogenism, hypofunction. Prenatal masculinization of the brain has been suggested in girls CAH. Hormones hypothalamic-pituitary-adrenal axis sex hormones interact extrahypothalamic regulatory centers brain, amygdala hippocampus. The is important processing emotion generation fear,...
Lumboperitoneal shunt (LPS), ventriculoperitoneal (VPS) and optic nerve sheath fenestration (ONSF) are accepted surgical therapies for medically refractory idiopathic intracranial hypertension (IIH). In the subset of patients with IIH venous sinus stenosis, dural stenting has emerged as an alternative approach.All cases stents at our institution were retrospectively reviewed. Eligibility criteria included documented papilledema stenosis dominant outflow system (gradient ≥10 mm Hg).Fifteen...
<h3>BACKGROUND AND PURPOSE:</h3> Although the combined end point of partial and complete recanalization is a well-established predictor good outcome following acute stroke intervention, few investigations have evaluated effect degree recanalization. We hypothesized that greater degrees would be associated with higher likelihood favorable functional outcomes. <h3>MATERIALS METHODS:</h3> Data from MERCI Multi MERCI—prospective single-arm trials endovascular mechanical thrombectomy for...
Abstract BACKGROUND Aneurysm recurrence after coiling has been associated with aneurysm growth, (re)hemorrhage, and a greater need for follow-up. The second-generation HydroCoil Embolic System (HES; MicroVention, Inc) consists of platinum core integrated hydrogel was developed to reduce through enhancing packing density healing within the aneurysm. OBJECTIVE To compare between HES bare coil (BPC) in new-generation Hydrogel Endovascular Treatment Trial (HEAT). METHODS HEAT is randomized,...
Arterial dissections account for 2% of strokes in all age groups, and up to 25% patients aged 45 years or younger. The safety endovascular intervention this patient population is not well characterized. We identified the Merci registry - a prospective, multi-center post-market database enrolling treated with Retriever thrombectomy device arterial dissection as most likely stroke etiology. Stroke presentation procedural details were obtained prospectively; data regarding complications,...
Due to anatomic features, including wide necks and incorporation of important branches, endovascular coiling middle cerebral artery (MCA) aneurysms has proved challenging. Stent assisted embolization may increase the likelihood successful treatment.Consecutive patients undergoing stent coil utilizing Neuroform from 2004 2009 were identified by hospital billing records. Procedural clinical information-including procedure related mortality morbidity long term outcomes-were then obtained...
We demonstrate that in nanostructured films of nanocrystalline silicon imbedded a hydrogenated amorphous matrix, carriers generated the region are transported out this and therefore do not recombine phase. Electron paramagnetic resonance (EPR) photoluminescence (PL) measurements show EPR PL from phase rapidly quenched as volume fraction Si nanocrystals exceeds about 30 vol. %. propose use similar structures to dramatically increase open circuit voltages solar cell devices.
Decompressive hemicraniectomy can be a life-saving treatment for uncontrolled elevations in intracranial pressure (ICP) due to trauma or space-occupying ischemic hemorrhagic stroke.1 Herniation the direction opposite site of craniectomy—paradoxical herniation—is an underrecognized and potentially fatal complication this procedure. It occur spontaneously may precipitated by lumbar puncture (LP) CSF shunt. is critical recognize treatable entity because standard interventions aimed at lowering...
The use of bare metal stents (BMS) to prevent recurrent stroke due stenosis the cerebral vasculature is associated with high rates restenosis. Drug-eluting (DES) may decrease this risk. We evaluated performance DES in a cohort patients treated at our institution. Consecutive were identified by case log and billing records; data regarding procedural details, clinical outcome angiographic follow-up was obtained retrospective chart review. Twenty-six (27 vessels; 14 vertebral origin (VO); 13...
A bstract : Recently discovered sexual dimorphism within developing brain structures such as the amygdala and hippocampus suggests that biological factors may account for many of sex differences in stress reactivity. In this study, we have relied on studies naturally occurring anomalous processes, congenital adrenal hyperplasia (CAH) Klinefelter's syndrome (XXY), to observe effects hormones chromosomes thought influence an individual's vulnerability stress. Brain magnetic resonance imaging...
Rapid thermal processing (RTP) is widely used for a variety of materials, including electronics and photovoltaics. Presently, optimization RTP done primarily based on ex-situ studies. As consequence, the precise reaction pathways phase progression during remain unclear. More awareness would better enable process foster increased adoption RTP, which offers numerous advantages synthesis broad range materials systems. To achieve this, we have designed developed instrument that enables real-time...
Monolithic interconnects in photovoltaic modules connect adjacent cells series, and are typically formed sequentially, involving multiple deposition scribing steps. Interconnect widths on the order of 500 μm every 10 mm result about 5% dead area, which does not contribute to power generation an interconnected solar panel. This work introduces alternative interconnection method capable producing interconnect less than 100 μm, can be accomplished a single pass after active layers electrodes....
