The prevalence of hearing loss increases with age and the presence of DM. Hearing loss was greatest at high frequencies. In all age groups, mild hearing loss was the most common form of hearing loss.

The development of molecular detection that allows rapid responses with high sensitivity and selectivity remains challenging. Herein, we demonstrate the strategy of novel bio-nanotechnology to successfully fabricate high-performance dopamine (DA) biosensor using DA Receptor-containing uniform-particle-shaped Nanovesicles-immobilized Carboxylated poly(3,4-ethylenedioxythiophene) (CPEDOT) NTs (DRNCNs). DA molecules are commonly associated with serious diseases, such as Parkinson's and Alzheimer's

SOX2 copy number and mRNA expression were analysed to examine the clinical significance of SOX2 activation in HNSCC. Gene expression signatures reflecting SOX2 activation were identified in an HNSCC cohort. Patients with HNSCC were classified into two subgroups according to the gene expression signature: SOX2-high and SOX2-low. The clinical significance of SOX2 activation was further validated in two independent cohorts. Moreover, clinical significance of SOX2 activation in response to radiother

OBJECTIVES: We have analyzed the correlation between the House-Brackmann (HB) scale and Facial Nerve Grading System 2.0 (FNGS 2.0) in patients with Bell palsy, and evaluated the usefulness of the new grading system. METHODS: Sixty patients diagnosed with Bell palsy from May 2009 to December 2010 were evaluated using the HB scale and FNGS 2.0 scale during their initial visit, and after 3 and 6 weeks and 3 months. RESULTS: The overall intraclass correlation coefficient (ICC) was 0.908 (P=0.000) an

INTRODUCTION: The objective of this study was to compare postoperative pain between single-port access total laparoscopic hysterectomy (SPA-TLH) using a transumbilical single-port system and conventional multi (three)-port access total laparoscopic hysterectomy (MPA-TLH). MATERIAL AND METHODS: A randomized controlled trial was conducted on 60 women who underwent SPA-TLH and MPA-TLH for benign gynecologic diseases between March 2014 and January 2015. Patients were randomly assigned to undergo SPA

Degree of hearing loss, gender, side, and recovery rate were similar in children and adults, but the rate of complete recovery was higher in children.

Twenty-eight of 45 patients (62.2%) revealed subjective improvement in tinnitus with TENS. TENS was more effective in patients with low-frequency tinnitus or with mild hearing loss. Symptomatic improvement in the electrical stimulation group was achieved for 1 month in most patients.

BACKGROUND & OBJECTIVES: Microbial infections in the normally sterile environment of the middle ear cavity in patients with otitis media trigger expression of Toll-like receptors (TLRs), cytokines, and nitric oxide. We evaluated the expression levels of TLR-1, -2, -4, -5, -6, and -9, interleukin (IL)-6, -8, -10, and -12, interferon-γ (IFN-γ), tumour necrosis factor-α (TNF-α), and nitric oxide (NO), in paediatric patients with otitis media with effusion (OME). METHODS: The levels of TLR, cytokine

Objectives. We have analyzed the correlation between the House-Brackmann (HB) scale and Facial Nerve Grading System 2.0 (FNGS 2.0) in patients with Bell palsy, and evaluated the usefulness of the new grading system.

BACKGROUND: To investigate the relationship with prognosis, various neurotological examinations evaluating all four nerves within the internal auditory canal were performed in patients with Bell's palsy. METHODS: A total of 69 consecutive patients with Bell's palsy were included. They were treated uniformly with steroid and an antiviral agent and underwent neurotological examinations consisting of electronystagmography, pure-tone audiometry (PTA), electroneurography (ENoG), caloric test, rotator

Introduction: Post-translational histone modifications directly modify chromatin structure to influence a wide variety of cellular events including gene expression, DNA replication and repair, and cell cycle control. While histone lysine methylation can confer either transcriptionally active or repressive states, the symmetric dimethylation of arginine residues on histone tails is generally associated with transcriptional repression. Overexpression and dysregulation of PRMT5, the major type II p

Vacuolar ATPases (V-ATPases) are multi-subunit ATP-dependent proton pumps necessary for cellular functions, including pH regulation and membrane fusion. The evidence suggests that the V-ATPase a-subunit’s interaction with the membrane signaling lipid phosphatidylinositol (PIPs) regulates the recruitment of V-ATPase complexes to specific membranes. We generated a homology model of the N-terminal domain of the human a4 isoform (a4NT) using Phyre2.0 and propose a lipid binding domain within the dis

Mantle cell lymphoma (MCL) is an incurable B cell malignancy, defined by the t(11;14) translocation and comprises 3-6% of non-Hodgkin lymphomas diagnosed annually. MCL is associated with a poor prognosis due to emergence of resistance to immuno-chemotherapy and targeted agents. Due to the late median age of diagnosis, aggressive chemotherapy and stem cell transplantation are often not realistic options. The average overall survival of patients with MCL is 5 years and for the majority of patients

Mantle cell lymphoma (MCL) is an incurable B-cell malignancy characterized by genetic dysregulation of cyclin D1 and activation of signaling pathways driving uncontrolled MCL cell proliferation and survival. Ibrutinib is an FDA-approved irreversible inhibitor of Bruton's tyrosine kinase (BTK), a downstream target of the B-cell receptor (BCR) pathway. While ibrutinib exhibits significant single-agent therapeutic activity in patients with relapsed/refractory MCL, the vast majority of MCL patients

A 48-year-old woman with cystic fibrosis and a previous left pneumonectomy had surgery planned for single lung transplantation under general anesthesia. Due to progressive dyspnea and recurrent respiratory infection, she could not maintain her normal daily life without lung transplantation. The anesthetic management and surgical procedure was expected to be difficult because of the left mediastinal shift and an asymmetric thorax after the left pneumonectomy, but the single lung transplantation w
