Increased Oxidative Stress, Inflammation, and Glutamate: Potential Preventive and Therapeutic Targets for Hearing Disorders

Publication date: Available online 22 November 2019Source: Mechanisms of Ageing and DevelopmentAuthor(s): Kadar N. Prasad, Stephen C. BondyAbstractHearing disorders constitute one of the major health concerns in the USA. Decades of basic and clinical studies have identified numerous ototoxic agents and investigated their modes of action on the inner ear, utilizing tissue culture as well as animal and human models. Current preventive and therapeutic approaches are considered unsatisfactory. Therefore, additional modalities should be developed. Many studies suggest that increased levels of oxidative stress, chronic inflammation, and glutamate play an important role in the initiation and progression of damage to the inner ear leading to hearing impairments. To prevent these cellular deficits, antioxidants, anti-inflammatory agents, and antagonists of glutamate receptor have been used individually or in combination with limited success. It is essential, therefore, to simultaneously enhance the levels of antioxidant enzymes by activating the Nrf2 (a nuclear transcriptional factor) pathway, dietary and endogenous antioxidant compounds, and B12-vitamins in order to reduce the levels of oxidative stress, chronic inflammation, and glutamate at the same time. This review presents evidence to show that increased levels of these cellular metabolites, biochemical or factors are involved in the pathogenesis of cochlea leading to hearing impairments. It presents scientific rationale for the...

Authors: Garbarino MC Abstract Although rabies, or hydrophobia, is one of the so-called forgotten tropical diseases, it still kills thousands of people each year, especially children living in rural areas of Asia and Africa. This terrible disease was once a much-feared threat throughout Europe, whose terrifying symptoms were described in a vast body of literature that was based on both science and popular beliefs. One notable individual whose name is linked to the fight against this disease is Adelchi Negri, a brilliant but unfortunate pupil of Camillo Golgi. At the beginning of the 20th century, Negri observed pec...

Authors: Vetri L, Messina LM, Drago F, D'Aiuto F, Vanadia F, Brighina F, Raieli V Abstract The aim of this study was to assess admissions, for headache, to the emergency department (ED) of the Di Cristina Children's Hospital in Palermo over a decade. The total number of ED admissions for headache was retrospectively analysed considering two 24- month periods: 2009-2010 and 2017-2018. Total admissions to the ED decreased from 55,613 to 50,096 (-10%) between the two periods considered, while the number of admissions for headache increased by 63.56% (p

Although CDBS has been in use for a long time, very little has been reported on its supposed effects on cognition, particularly in relation to implants in the subthalamic nucleus. The results of the rare studies that do exist are controversial, and in many cases the studies have several design ...

This study assesses the current practices of physicians in Lebanon routinely involved in ischemic stroke (IS) management. We conducted a prospective observational study of patients hospitalized at 8 different Lebanese hospitals in the period August 1, 2015 to July 31, 2016, with a diagnosis of acute stroke. Baseline characteristics and data on diagnostic studies, as well as treatments received during hospitalization and at discharge, were collected and analyzed. Two hundred and three strokes/transient ischemic attacks (TIAs) were recorded but only 173 patients (85%) with ischemic events were included in the study. The pati...

Authors: Goldhardt MG, Andreia A, Dorneles GP, da Silva IR, Pochmann D, Peres A, Rostirola Elsner V Abstract Our aim was to evaluate the impact of a single bout of exercise, consisting of a gait training session with body weight support (BWS), on histone acetylation status (global histone H4 and H3 acetylation levels), brain-derived neurotrophic factor (BDNF) levels, and oxidative stress markers in peripheral blood of individuals with chronic spinal cord injury (SCI). We also set out to compare these responses with those recorded after gait training performed using a walker and with no BWS. The subjects (nearly all...

Authors: de Sire A, Mauro A, Priano L, Baudo S, Bigoni M, Solaro C Abstract Multiple sclerosis (MS) is a chronic disease of the central nervous system, characterized by demyelinization and axonal loss resulting, in 66% of cases, in upper limb motor impairment. The effects of constraint-induced movement therapy (CIMT) have recently been investigated in MS patients. The aim of this randomized single-blind pilot study was to assess the effects of CIMT on upper limb activity, specifically smoothness of movement, in patients affected by progressive MS. Patients affected by MS, and reporting reduced use primarily of one ...

The objective of this psychometric study was to validate the Italian version of the BI in a population of patients with Parkinson's disease (PD). The study was conducted at three neurological and rehabilitation centres in Rome, Italy. The BI was administered to outpatients with PD. The reliability of the scale was assessed using Cronbach's alpha for internal consistency; the intra-class correlation coefficient (ICC) was used to measure its intra- and inter-rater reliability. Pearson's correlation coefficient was calculated to evaluate its validity, comparing it with the Parkinson's disease Questionnaire (PDQ-39), the Itali...

Authors: De Bartolo D, Spitoni GF, Iosa M, Morone G, Ciancarelli I, Paolucci S, Antonucci G Abstract In recent years, cognitive theories have increasingly influenced the approach to motor rehabilitation. The connection between different aspects of cognitive and motor function is increasingly documented, underlining the importance of developing rehabilitation projects that take cognitive aspects into account. The aim of this non-systematic review is to highlight the relationship between cognition and motion and, in the light of new rehabilitation technologies, to better define how aspects of cognition can affect mot...
