The aim of this study was to evaluate transcranial attenuation for bone conduction as a function of each frequency by hearing loss types on subjects of unilateral hearing loss or unilateral with bilateral hearing loss. Methods: A total of 82 subjects with sensorineural (40 ears),

The transcranial attenuation was analyzed for 82 ears with the differences over 10 dB HL in all frequencies (0.25-4 kHz) by air conduction audiometry. The transcranial attenuation at each frequency was obtained by bone conduction threshold without masking. Results: We observed a significant in the mean of transcranial attenuation for bone conduction of the overall subjects. It was closed to 0-9 dB HL at 0.25 kHz to 2 kHz and 13 dB HL at 3 to 4 kHz. There are more difference in principal the transcranial attenuation for bone conduction in high frequency than a low frequency. Conclusion: Therefore, the conductive and mixed hearing loss always need to consider about the masking by crosshearing. The cross-hearing, however, needs to consider by type of hearing loss because the transcranial attenuation of bone conduction as a function of each frequency depends on hearing loss types. Further research should work for the transcranial attenuation of bone conduction by degrees of hearing loss.

Magnetic Domain-Wall Tilting due to Domain-Wall Speed Asymmetry [article]

Chiral magnetic materials provide a number of challenging issues such as the highly efficient domain wall (DW) and skyrmion motions driven by electric current, as of the operation principles of emerging spintronic devices. The DWs in the chiral materials exhibit asymmetric DW speed variation under application of in plane magnetic field. Here, we show that such DW speed asymmetry causes the DW tilting during the motion along wire structure. It has been known that the DW tilting can be induced by

However, our experimental observations manifests that there exists another dominant process with the DW speed asymmetry caused by either the Dzyaloshinskii Moriya interaction (DMI) or the chirality dependent DW speed variation. A theoretical model based on the DW geometry reveals that the DW tilting is initiated by the DW pinning at wire edges and then, the direction of the DW tilting is determined by the DW speed asymmetry, as confirmed by a numerical simulation. The present observation reveals the decisive role of the DW pinning with the DW speed asymmetry, which determines the DW geometry and consequently, the dynamics.

ObjectiveMyocardial ischaemia is a leading cause of acute heart failure (AHF). However, optimal revascularisation strategies in AHF are unclear. We aimed to compare two revascularisation strategies, coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI), in patients with AHF.MethodsAmong 5625 consecutive patients enrolled prospectively in the Korean Acute Heart Failure registry from March 2011 to February 2014, 717 patients who received CABG or PCI during the index

We compared adverse outcomes (death, rehospitalisation for HF aggravation or cardiovascular causes, ischaemic stroke and a composite outcome of death and rehospitalisation for HF aggravation or cardiovascular causes) with the use of propensity score matching.ResultsFor the propensity score-matched cohort with 190 patients, CABG had a lower risk of all-cause mortality than PCI (83 vs 147 deaths per 1000 patient-years; HR 0.57, 95% CI 0.34 to 0.96, p=0.033) during the median follow-up of 4 years. There was also a trend towards lower rates of rehospitalisation due to cardiovascular events or HF aggravation. Subgroup analysis revealed that the adverse outcomes were significantly lower in the CABG group than in PCI group, especially in patients with old age, three-vessel diseases, significant proximal left anterior descending artery disease and those without left main vessel disease or chronic total occlusion.ConclusionsCompared with PCI, CABG is associated with significant lower all-cause mortality in patients with AHF. Further studies should evaluate proper revascularisation strategies in AHF.Clinical trial registrationNCT01389843; Results.

Researchers use a search engine for finding what they want to read from an article database. Because the search engine normally returns a large number of articles as a search result, they could not find the articles that they want. A ranking method solves this problem by giving proper ranks to articles. In this paper, we define the articles that researchers want to read as high quality articles, and propose a ranking method, ArtRank, to give high ranks to these articles. For determining the

We point out the problem of the existing impact factor that is employed for determining the reputation of a journal or a conference, and propose its solution. Also, for solving the problem of underestimation of the recent articles, ArtRank analyzes the publication years of articles and applies the result of analysis to the ranking computation process. We show the effectiveness of ArtRank by comparing its search results with those of prior article ranking methods.

2011 Clinical Endoscopy  
Gastrectomy with lymph node (LN) dissection was considered as the only standard treatment of early gastric cancer (EGC) in the past, but a curative endoscopic treatment is widely used recently. Endoscopic treatment of EGC is less invasive than surgery, reduces medical costs, improves quality of life of patients, and is as effective as surgery. Endoscopic treatment for EGC is performed more frequently with the increased detection of EGC by universal health check-ups. But curative endoscopic

Traditional indication of endoscopic treatment was an elevated type cancer of less than 2 cm in size (EGC І or ІІa) and a depressed type of less than 1 cm without ulcer (EGC ІІc) among differentiated EGCs confined to the mucosa. 1 This was to minimize the possibility of LN metastasis and local recurrence. With the recent development of endoscopic maneuver and the accessory tools, the introduction of endoscopic submucosal dissection (ESD) enabled endoscopic treatment of lesions deemed untreatable in the past. ESD improved en bloc resection rate and complete resection rate regardless of the lesions location and size, compared to the conventional endoscopic mucosal resection. ESD also enabled dissection of submucosal layer as deep as 1,500 µm and extended the indi-

Objective: The purpose of this study was to evaluate the clinical presentation and surgical outcome in patients with symptomatic discal cyst. Methods: The authors reviewed consequent 9 patients in whom microscopic excision of the discal cyst with or without additional discectomy for discal cyst from 2005 to 2012. Diagnostic imagings including simple radiographs, computed tomography with discogram and magnetic resonance images were performed in each case. The patients were reviewed to evaluate

Results: In all patients, discal cyst was located in the lumbar region and they presented with back pain and unilateral radiating pain. The preoperative magnetic resonance images (MRI) and computed tomography (CT) scan with discogram showed a connection between the cyst and the involved intervertebral disc. All patients obtained immediate relief of symptoms after microscopic excision of discal cyst. There were no recurrent lesions during follow-up period. The mean preoperative visual analogue scale (VAS) was 7.8 when compared with 2.6 in preoperative assessment. All patients obtained excellent or good outcome according to modified MacNab's criteria. Conclusion: Discal cysts are rare lesions that can lead to back pain and refractory sciatica. Microscopic excision of the cyst can achieve remarkable improvement of symptoms.
