Plants are one of the best sources to obtain a variety natural surfactants in field green synthesizing material. Sambucus ebulus, which has unique properties, been considered promising material traditional Asian medicine. In this context, zinc oxide nanoparticles (ZnO NPs) were prepared using S. ebulus leaf extract, and their physicochemical properties investigated. X-ray diffraction (XRD) results revealed that ZnO NPs highly crystalline, having wurtzite crystal structure. The average...
Although vascular dementia is the second leading cause of and often underdiagnosed, there are no drugs yet approved for treatment dementia. In this study, it demonstrated that water extract Triticum aestivum L. (TALE) some its components have protective effects against dementia-induced damage by preserving myelin sheath inhibiting astrocytic activation. The memory test used a model utilizing bilateral ligation carotid arteries rats. TALE, components, such as starch, total dietary fiber...
Exposure to aircraft noise has been shown have adverse health effects, causing annoyance and affecting the health-related quality of life, sleep, mental states those exposed it. This study aimed determine sleep in participants residing near an airfield evaluate relationship between levels quality. Neighboring regions a military were divided into three groups: high exposure group, low control group. A total 1082 (aged 30–79 years) completed comprehensive self-administered questionnaire...
Zinc oxide nanocrystals (ZnO NCs) were synthesized via a sol–gel method. After the synthesis, their surface was modified using 2,2,2-trifluoroacetic acid followed by ultraviolet (UV) treatment of resulting fluorinated ZnO (F-ZnO) NC thin films. The chemical bonding therein and structural electrical properties investigated. Moreover, oxygen vacancy electroluminescence densified NCs evaluated. effects both UV fluorination on morphological characteristics F-ZnO films established. Based results,...
Symptoms of normal pressure hydrocephalus (NPH) and Alzheimer’s disease (AD) are somewhat similar, it is common to misdiagnose these two conditions. Although there fluid markers detectable in humans with NPH AD, determining which biomarker optimal representing genetic characteristics consistent throughout species poorly understood. Here, we hypothesize that can be differentiated from AD mRNA biomarkers unvaried proximity telomeres. We examined human caudate nucleus tissue samples for the...
Methamphetamine (METH) is a powerful neurotoxic psychostimulant affecting dopamine transporter (DAT) activity and leading to continuous excess extracellular levels. Despite recent advances in the knowledge on neurobiological mechanisms underlying METH abuse, there are few effective pharmacotherapies prevent abuse brain damage neuropsychiatric deficits. α-Pinene (APN) one of major monoterpenes derived from pine essential oils has diverse biological properties including anti-nociceptive,...
The aim of study is to find conditions that aggravate auditory deprivation in patients with symmetric hearing loss after unilateral digital, non-linear aid (HA). In the retrospective case-comparison study, we assessed 47 sensorineural (SNHL), wearing conventional HAs. Audiological outcomes were >1 year HA fitting (mean duration, 31.0 months). Pure-tone audiometry HA-aided and HA-unaided was performed over time. Word recognition score (WRS) evaluated at most comfortable listening level....
Objectives: To determine the level of aircraft noise exposure and how it relates to hearing loss, investigate association between anxiety depression in subjects residing adjacent a military airbase. Methods: The study was conducted upon 898 inhabitants ages 30-79, living near airbase Jeonra-do. were divided into three noise-exposure groups: high-exposure, low-exposure, control group. cut-values 80 60 on Weighted Equivalent Continuous Perceived Noise Level scale. A self-administered...
Objective Loss of signal (LOS) during intraoperative neuromonitoring (IONM) robotic or endoscopic thyroidectomy via a retroauricular approach (RAT) and conventional open (COT) was investigated to compare the risk recurrent laryngeal nerve (RLN) injury between two groups. Study Design Original article. Methods This is retrospective case series study performed May 2014 September 2016. IONM using NIM 3.0 system (Medtronic Xomed, Inc., Jacksonville, FL) used for this study. Pre‐ postoperative...
Objectives: This study was conducted to investigate the effects of aircraft noise exposure on children’s mental health problems such as depression and personality. Methods: We obtained data from examinations school children in vicinity Gunsan airport. survey rural area, during 2009. The population included 195 attending 4th 6th grade 6 elementary schools near Based 60 Weighted Equivalent Continuous Perceived Noise Level (WECPNL) measures noise, participants were divided into 2 groups; group...
Methamphetamine (METH) is a powerful neurotoxic psychostimulant characterized to affects activity of dopamine transpoters leading blockage (DA) uptake into the synaptic vesicle as well DA reuptake through plasma membrane inducing release, which resulted in continuous excess extracellular levels cleft. Orexinergic system has been reported play crucial roles regulation arousal, wakefulness, and motivated behaviors for drug abuse. In this study, we have investigated orexin and/or receptors on...
PP-29-183 Background/Aims: There have been several studies on the relationship between noise and sleep disorder, but results vary. This study was aimed to calculate prevalence of poor evaluate degree Gunsan airfield quality. Methods: Drawing up a map done by following integrated model, considering daylight night flying, takeoff turnaround, also revision verification were conducted. On basis map, neighboring regions divided into 3 groups: high exposed group with 80 weighted equivalent...
PP-29-181 Background/Aims: Although there have been many studies on health effects of nocturnal traffic noise, the relationship between aircraft noise and mental are limited. This study was aimed to evaluate dose-response degree Gunsan airfield health. Methods: Drawing up a map done by following integrated model, considering daylight night flying, takeoff turnaround, also revision verification were conducted. On basis map, neighboring regions divided into 3 groups: high exposed group with 80...
Abstract Zoletil® (ZOL) is a combination drug of tiletamine, dissociative anesthetic and zolazepam, minor tranquilize, which has been used to induce short-term anesthesia in various animals. Depending on the administered dose, effects ZOL can range from sedation anesthesia. Here, we aimed determine neurotoxicity elucidate its mechanism action using BV-2 microglial cells. The results MTT reduction assay TUNEL staining revealed that induced neuronal toxicity apoptosis caused via...
