In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Question: Context: To test device integrity and objective auditory reaction for cochlear implant patients intraoperatively.', 'Our protocol for intraoperative testing of the implant device includes device electrode impedance test and neural response telemetry (NRT), which measures the electrically evoked auditory nerve compound action potentials (ECAP).', 'We completed electrode integrity tests and NRT intraoperatively on 40 patients with the Nucleus CI24M cochlear implant. We have measured normal implant function on all 40 patients and obtained ECAP results from 39 patients. Out of 33 patients with normal inner ear, typical ECAPs were recorded in 195 electrodes in all 198 testing electrodes(98.5%). In 7 patients with inner ear Mondini dysphasia, affirmative ECAP waveforms were recorded in 26 electrodes in all 42 testing electrodes. The basal electrode ECAP threshold was higher than that of the epical one.\Question: Do [ The intraoperative application of neural response telemetry with the nucleus CI24M cochlear implant ]?

Answer: The intraoperative measurements of device function and NRT are quite simple, quick and with high accuracy. Inner ear malformation is an important factor that may affect NRT results.

Question: Context: Transport across the blood-brain barrier (BBB) is an important mediator of beta-amyloid (A) accumulation in the brain and a contributing factor in the pathogenesis of Alzheimer's disease (AD). One of the receptors responsible for the transport of A in the BBB is the low density lipoprotein receptor-related protein 1 (LRP1). LRP1 is susceptible to proteolytic shedding at the cell surface, which prevents endocytic transport of ligands. Previously, we reported a strong inverse correlation between LRP1 shedding in the brain and A transit across the BBB. Several proteases contribute to the ectodomain shedding of LRP1 including the -secretase, a desintegrin and metalloproteinase domain containing protein 10 (ADAM10).", 'The role of ADAM10 in the shedding of LRP1 and A BBB clearance was assessed through pharmacological inhibition of ADAM10 in an in vitro model of the BBB and through the use of ADAM10 endothelial specific knock-out mice. In addition, an acute treatment paradigm with an ADAM10 inhibitor was also tested in an AD mouse model to assess the effect of ADAM10 inhibition on LRP1 shedding and Abrain accumulation.', 'In the current studies, inhibition of ADAM10 reduced LRP1 shedding in brain endothelial cultures and increased A42 transit across an in vitro model of the BBB. Similarly, transgenic ADAM10 endothelial knockout mice displayed lower LRP1 shedding in the brain and significantly enhanced A clearance across the BBB compared to wild-type animals. Acute treatment with the ADAM10-selective inhibitor GI254023X in an AD mouse model substantially reduced brain LRP1 shedding and increased A40 levels in the plasma, indicating enhanced A transit from the brain to the periphery. Furthermore, both soluble and insoluble A40 and A42 brain levels were decreased following GI254023X treatment, but these effects lacked statistical significance.\Question: Does inhibition of ADAM10 promote the clearance of A across the BBB by reducing LRP1 ectodomain shedding?

Answer: These studies demonstrate a role for ADAM10 in the ectodomain shedding of LRP1 in the brain and the clearance of A across the BBB, which may provide a novel strategy for attenuating A accumulation in the AD brain.

Question: Context: MicroRNA-622 has been proven down-regulated in many human malignancies and correlated with tumor progression. However, its role in esophageal squamous cell carcinoma (ESCC) is still unclear. The aim of this study was to explore the expression and function of miR-622 in ESCC.', 'Using quantitative RT-PCR, we detected miR-622 expression in ESCC cell lines and primary tumor tissues. The association of miR-622 expression with clinicopathological factors and prognosis was also analyzed. Then, the effects of miR-622 on the biological behavior of ESCC cells were investigated. At last, the potential regulatory function of miR-622 on E2F1 expression was confirmed.', 'miR-622 was found to be down-regulated in ESCC tissues and cell lines. Decreased miR-622 expression was closely correlated with aggressive clinicopathological features and poor overall survival. Multivariate regression analysis corroborated that low level of miR-622 expression was an independent unfavourable prognostic factor for patients with ESCC. Up-regulation of miR-622 could significantly reduce ESCC cell proliferation, enhance cell apoptosis, and impair cell invasion and migration in vitro, while down-regulation of miR-622 showed opposite effects. Further, E2F1 was confirmed as a direct target of miR-622 by using Luciferase Reporter Assay.\Question: Does miR-622 functions as a tumor suppressor and directly target E2F1 in human esophageal squamous cell carcinoma?

Answer:
These findings indicate that miR-622 may act as a tumor suppressor in ESCC and would serve as a potential therapy target for this disease.
