4-Aminopyridine (4AP) Enhances Acetylcholine Output from the Rat Cerebral Cortex in vivo

1982

Publisher Summary This chapter discusses a study to analyze the effect of 4-aminopyridine (4AP) administration on cortical acetylcholine (ACh) output. The study was done on adult male Wistar rats under urethane or pentobarbital anesthesia. A small Perspex cylinder filled with eserinized Ringer solution was applied on the exposed cerebral cortex. The solution in the collecting cylinder was removed every 10 min and its ACh content was determined by bioassay on the dorsal muscle of the leech. In urethane anaesthetized rats, the control ACh output was 0.98 ± 0.16 ng/min/cm2 and the administration of 4AP (3 mg/kg i.p.) was followed by a rapid increase in ACh output lasting at least 40 min. The i…

Eroded enamel rehardening using two intraoral appliances designs in different times of salivary exposure.

2019

Background The aim of this study was evaluated the eroded enamel rehardening potential using upper palatal and lower buccal removable appliances in different times of salivary exposure (30 min, 1h, 2h, 12h) after a single erosive challenge event. Material and Methods After initial surface hardness evaluation, bovine enamel blocks were eroded in vitro (0.01 M hydrochloric acid, pH 2.3, 30 seconds), selected (n = 160) and randomly assigned to the two appliance designs and twenty volunteers. Four enamel blocks were inserted in each removable appliance. On the in situ phase, the volunteers were instructed to use the upper palatal and lower buccal appliances simultaneously for 12 nonconsecutive …

Uvulopalatopharyngoplasty with tonsillectomy in the treatment of severe OSAS

2009

Objective: To establish the efficacy of uvulopalatopharyngoplasty with tonsillectomy for treating selected patients with severe obstructive sleep apnea syndrome Methodology: Retrospective study of patients who underwent clinical/instrumental evaluation and surgical treatment. Setting: University ENT division with a tertiary snoring referral center Participants: Twenty-two patients with normal body mass index affected by severe obstructive sleep apnea syndrome- Main outcome measures: Pre and post operative cardiopulmonary monitoring during sleep, daytime sleepiness evaluation, post treatment complication recording. Results: Complete response to therapy was obtained in 78% of patients. Four p…

Position paper on the management of patients with obstructive sleep apnea and hypertension: joint recommendations by the European Society of Hyperten…

2012

This article is aimed at addressing the current state of the art in epidemiology, pathophysiology, diagnostic procedures and treatment options for appropriate management of obstructive sleep apnea (OSA) in cardiovascular (particularly hypertensive) patients, as well as for the management of cardiovascular diseases (particularly arterial hypertension) in OSA patients. The present document is the result of the work done by a panel of experts participating in the European Union COST (COoperation in Scientific and Technological research) ACTION B26 on OSA, with the endorsement of the European Respiratory Society (ERS) and the European Society of Hypertension (ESH). These recommendations are par…

Varkaus yhteiskunnallisten murrosten näyttämönä 1900-luvun alusta nykypäivään

2020

Tässä kymmenestä artikkelista koostuvassa kokoomateoksessa tarkastellaan Varkautta rakennemuutoksen kanssa kamppailevana pienenä kaupunkina historiallisia dokumentteja sekä vuosina 2016–2017 kerättyjä kysely- ja haastatteluaineistoa hyödyntäen. Pitkän teollisuushistorian omaava Varkauden kaupunki on tämän vuosituhannen ensimmäisinä vuosikymmeninä menettänyt suuren osan teollisista työpaikoistaan ja sen väestö on supistunut voimakkaasti. Kuitenkin koko aikuisväestöä edustava kysely kertoo, että varkautelaiset ovat tyypillisesti tyytyväisiä työhönsä, sosiaalisiin suhteisiinsa ja elämäänsä muutenkin. Varkaus nähdään turvallisena ja hyvän elämän puitteet tarjoavana asuinpaikkana. Hyvinvoinnin t…

Testing the direct and moderator effects of the stressor-detachment model over one year : A latent change perspective

2018

ABSTRACTTo test the direct and moderator effects of the stressor–detachment model from a long-term perspective, we investigated whether workload and detachment are related to changes in exhaustion and sleep difficulties over one year. We also examined whether detachment attenuates the relationship between high workload and these outcomes both cross-sectionally and over time. Questionnaire data with 1722 respondents at Time 1 and 1182 respondents at Time 2 were collected. We used a latent change score approach to analyse the data in order to identify intra-individual change among the studied constructs. Our results showed that high workload and low detachment at baseline were related to an i…

Effect of Production Phase on Bottle-Fermented Sparkling Wine Quality

2015

This review analyzes bottle-fermented sparkling wine research at each stage of production by evaluating existing knowledge to identify areas that require future investigation. With the growing importance of enological investigation being focused on the needs of the wine production industry, this review examines current research at each stage of bottle-fermented sparkling wine production. Production phases analyzed in this review include pressing, juice adjustments, malolactic fermentation (MLF), stabilization, clarification, tirage, lees aging, disgorging, and dosage. The aim of this review is to identify enological factors that affect bottle-fermented sparkling wine quality, predominantly …

Immobilisation of yeasts on oak chips or cellulose powder for use in bottle-fermented sparkling wine

2019

[EN] Sparkling wine production comprises two successive fermentations performed by Sacharomyces cerevisiae strains. This research aimed to: develop yeast immobilisation processes on two wine-compatible supports; study the effects of yeast type (IOC 18-2007 and 55A) and the immobilisation support type (oak chips and cellulose powder) on the fermentation kinetics, the deposition rate of lees and the volatile composition of the finished sparkling wine; compare the fermentation parameters of the wines inoculated with immobilised or non-immobilised cells. Proper immobilisation of yeast on oak chips and cellulose powder was demonstrated by electron microscopy. Total sugar consumption occurred in …
