Eukaryotic cells internalize transmembrane receptors via clathrin-mediated endocytosis, but it remains unclear how the machinery underpinning this process is regulated. We recently discovered that membrane-associated muniscin proteins such as FCHo and SGIP initiate endocytosis by converting the AP2 clathrin adaptor complex to an open, active conformation that is then phosphorylated (Hollopeter et al., 2014). Here we report that loss of ncap-1, the sole C. elegans gene encoding an adaptiN Ear-binding Coat-Associated Protein (NECAP), bypasses the requirement for FCHO-1...

BACKGROUND: Patient anxiety is an often overlooked complication of pleural diagnostic and therapeutic procedures. Listening to music is effective in reducing patient anxiety in some endoscopy procedures but has not yet been evaluated in pleural procedures. METHODS: Consecutive patients undergoing therapeutic pleural procedures were randomised to music and control groups. Participants in the music group listened to self selected music using ear-bud headphones for the duration of the procedure...

Phlorotannins, phenolic compounds produced exclusively by seaweeds, have been reported to possess various pharmacological properties. However, there have been few works on these compounds from Mediterranean seaweeds. In this study, we investigated the phytochemical analysis and pharmacological potential of phlorotannin-rich fractions from three brown seaweeds collected along the Tunisia coast: Cystoseira sedoides (PHT-SED), Cladostephus spongeosis (PHT-CLAD), and Padina pavonica (PHT-PAD). Phytochemical determinations showed considerable differences in total phenolic content (TPC) and phlorotannin content (PHT)...

Hypohidrotic ectodermal dysplasia (HED), also known as anhidrotic ectodermal dysplasia, is characterized by the clinical manifestations of less sweat or no sweat, sparse or no hair, tooth agenesis and/or abnormal tooth morphology. The characteristics of alpaca ear hair differ from the back hair. The ectodysplasin A (EDA) signaling pathway has a regulatory effect on skin development and hair growth. The aim of the present study was to study the effects of EDA on alpaca hair growth by examining the mRNA and protein expression levels of EDA in alpaca ear and back skin by reverse transcription‑quantitative polymerase chain reaction and western blot analysis, respectively...

BACKGROUND Ramsay Hunt syndrome is a rare otologic complication resulting from varicella zoster virus reactivation that can present with a myriad of clinical presentations. Most common being triad of ear pain, vesicles at auricle, and ear canal with same side facial palsy. CASE REPORT We report a case of a 29-year-old male with a human immunodeficiency virus (HIV) infection who presented with left facial palsy, vesicles, pain in the left ear, dysphagia, dizziness, and headache resulting from multiple cranial nerves involvement such as cranial nerve V, VII, VIII, IX, and X...

OBJECTIVE: To systematically assess auditory characteristics of a large cohort of patients with genetically confirmed myotonic dystrophy type 2 (DM2). METHODS: Patients with DM2 were included prospectively in an international cross-sectional study. A structured interview about hearing symptoms was held. Thereafter, standardized otologic examination, pure tone audiometry (PTA; 0.25, 0.5, 1, 2, 4, and 8 kHz), speech audiometry, tympanometry, acoustic middle ear muscle reflexes, and brainstem auditory evoked potentials (BAEP) were performed...

OBJECTIVE: This study evaluated the relationship between radiation and Eustachian tube dysfunction, and examined the radiation dose required to induce otitis media with effusion. METHODS: The function of 36 Eustachian tubes in 18 patients with head and neck cancer were examined sonotubometrically before, during, and 1, 2 and 3 months after, intensity-modulated radiotherapy. Patients with an increase of 5 dB or less in sound pressure level (dB) during swallowing were categorised as being in the dysfunction group...

HYPOTHESIS: This study evaluates the degree of preservation of hair cells, supporting cells, and innervating dendritic processes after cochlear implantation in the human using immunohistochemical methods. BACKGROUND: Surgical insertion of a cochlear implant electrode induces various pathologic changes within the cochlea including insertional trauma, foreign body response, inflammation, fibrosis, and neo-osteogenesis. These changes may result in loss of residual acoustic hearing, adversely affecting the use of hybrid implants, and may result in loss of putative precursor cells, limiting the success of future regenerative protocols...

OBJECTIVE: Over 5% of the world's population suffers from disabling hearing loss. Stem cell homing in target tissue is an important aspect of cell-based therapy, which its augmentation increases cell therapy efficiency. Deferoxamine (DFO) can induce the Akt activation, and phosphorylation status of AKT (p-AKT) upregulates CXC chemokine receptor-4 (CXCR4) expression. We examined whether DFO can enhance mesenchymal stem cells (MSCs) homing in noise-induced damaged cochlea by PI3K/AKT dependent mechanism...

Skin lesions are often submitted to oral and maxillofacial pathology practices. The purpose of this study is to evaluate the frequency, distribution, variability, and composition of dermatologic lesions within a large oral and maxillofacial pathology biopsy service. An IRB-approved retrospective search of skin lesions diagnosed at University of Florida oral and maxillofacial pathology biopsy service between 1994 and 2015 was performed. 2487 cases were included in the study. Gender was reported in 2466 cases, of which 59% were male and 41% female...

BACKGROUND: A few options of extracranial donor vessels exist for utilization in intracranial vascular bypass procedures. To our knowledge, the use of an internal thoracic artery for cerebral revascularization has not been studied previously. Hence, this cadaveric feasibility study was performed. METHODS: The internal thoracic artery was dissected in five adult cadaveric specimens. The proximal diameter, distal diameter, and the length of the vessel were measured and recorded...

AIM: This study aimed to examine associations between structural MRI and concurrent motor, neurological and neurobehavioral measures at 30-32 weeks postmenstrual age (PMA; 'Early'), and at term equivalent age ('Term'). METHOD: In this prospective cohort study, infants underwent Early MRI (n = 119; 73 male; median 32 weeks 1 day PMA) and Term MRI (n = 102; 61 male; median 40 weeks 4 days PMA) at 3 T. Structural images were scored generating white matter (WM), cortical gray matter, deep gray matter, cerebellar and global brain abnormality scores...

Serous otitis media with effusion (OME) is a middle ear inflammatory response to allergens and microbes which stimulate leukocytes to produce different inflammatory mediators after obstruction of Eustachian tube. Here, we investigated the levels of these mediators, IL-17 and IL-23, in serum and middle ear fluids of children with OME. 75 patients with otitis media and 75 age and sex-matched healthy controls were enrolled in this study. IL-17 and IL-23 levels in serous secretion of the patients and their serum levels were measured in both groups by ELISA...

OBJECTIVE: The binaural-hearing system interaurally compares inputs, which underlies the ability to localize sound sources and to better understand speech in complex acoustic environments. Cochlear implants (CIs) are provided in both ears to increase binaural-hearing benefits; however, bilateral CI users continue to struggle with understanding speech in the presence of interfering sounds and do not achieve the same level of spatial release from masking (SRM) as normal-hearing listeners...
