Rheumatoid arthritis (RA) and periodontitis share risk factors inflammatory pathways that could be related to cytokines, such as interleukin (IL)-6, IL-8, IL-17A, tumour necrosis factor-α (TNF-α). The aim of this study was compare periodontal status salivary levels selected cytokines between patients diagnosed with RA periodontitis. were assessed for the potential influence anti-rheumatic therapy.One hundred six enrolled in a cross-sectional study. Medical assessment examination performed 35...

Obestatin is a 23-amino acid peptide derived from proghrelin, common prohormone for ghrelin and obestatin. Previous studies showed that obestatin exhibited some protective therapeutic effects in the gut. The aim of our presented study was to examine effect treatment with on trinitrobenzene sulfonic (TNBS)-induced colitis. In rats anesthetized ketamine, colitis induced through intrarectal administration 25 mg 2,4,6-trinitrobenzene (TNBS). administered intraperitoneally at doses 4, 8, or 16...

Simple loudness adaptation for pure tones was measured at frequencies from 0.125 to 16 kHz and sensation levels 5 60 dB. Sixteen young listeners with normal hearing participated in four experiments. Most of the measurements were obtained by method successive magnitude estimation; some also matching. The two indices gave similar results. At all frequencies, increased as level decreased. After 6 min, average declined most about 20% 40-dB (SL) between 70% almost 100% 5-dB SL. Adaptation...

A psychophysical pitch function, describing the relation of perceived magnitude to frequency a pure tone, was determined by absolute estimation. Pitch estimates were made listeners with relative and possessors for 27 tones spanning range 31.5–12 500 Hz in 1/3 octave steps. Results show that plotted log–log coordinates, is steeper below 200 than at higher frequencies. It hypothesized function’s bend may reflect diversity neurophysiological mechanisms encoding ranges above Hz. The variation...

Loudness adaptation was measured for pure tones at 4, 12, 14, and 16 kHz. In three experiments, a total of 87 young listeners judged--by the method successive magnitude estimation--the loudness over 6-min exposure period. Thresholds were by an adaptive 2IFC procedure. Although earlier measurements had shown that near threshold increases with frequency, these new data reveal increase is especially marked higher sensation levels. Thus, 40 dB SL, period declined 18% 4 kHz 94% Moreover, 4-kHz...

Abstract The purpose of the study was to compare auditory judgments sound clarity music examples recorded in a concert hall with predictions made from impulse response signal same hall. Auditory were use two methods: by rating on numerical scale endpoints, and absolute magnitude estimation. Results obtained both methods then compared against values indices, C 80 50 , determined hall, measured places which microphone located during recording examples. show that index yield similar rank order...

Periodontitis is a major risk factor of systemic diseases with inflammatory etiology. Numerous studies have established the connection between periodontal condition and diabetes, but there are no reports in literature on relationship periodontitis other pancreas conditions. The activity pancreatic enzymes an important parameter damage, also diagnostic marker acute chronic pancreatitis, bleeding index determines activity. To date, status both above-mentioned conditions has not been...

Loudness levels (LL) of musical scale segments played pianissimo and fortissimo were predicted for 11 orchestral instruments, using Zwicker’s Stevens’ Mark VI procedures loudness calculation. The results show that the dynamic LL range instruments depends not only on sound-pressure level range, but is also influenced by changes in spectral envelope accompany gradations sound. As sound louder, its bandwidth extends to high frequencies, increase (SPL) greater partials than low ones. Due...

Background.In order to regenerate periodontal tissues, necessary conditions for this process must be created during surgery, primarily by allowing uninfected adhesion of the clot root surface, and then its stable position in defect.Objectives.The aim secondary analysis was evaluate early postoperative healing papillary incisions correlations with patient-, site-and technique-related factors following guided tissue regeneration (GTR) treatment intrabony defects patients aggressive...

A few studies have reported that, under certain conditions, thresholds following exposure to a sound may be lower than those measured without prior stimulation. For example, Rubin [J. Acoust. Soc. Am. 32, 670–681 (1960)] found 7-dB negative shift in threshold, for 20-ms tone presented 160 ms after termination of low-level cue tone. This ‘‘auditory facilitation’’ was obtained with an up-and-down psychophysical method. In the present study, auditory facilitation reexamined using adaptive,...

The article reports three experiments conducted to determine whether musicians possess better ability of recognising the sources natural sounds than non-musicians.The study was inspired by which indicate that musical training develops not only hearing, but also enhances various non-musical auditory capabilities.Recognition and detection thresholds were measured for recordings environmental presented in quiet (Experiment 1) background a noise masker 2).The listener's sound source recognition...

Abstract An experiment was conducted to explore the effect of pitch strength pure tones constituting a dyad on accuracy musical interval identification. Pitch controlled by presenting intervals in different frequency regions and varying their duration. The were organized into 18 blocks made up combination three octaves: second (65.4-130.8 Hz), fourth (261.6- 523.3 sixth octave (1047-2093 six tone durations, ranging 50-2000 ms octave, 10-500 two higher ones. results indicate that...

Modern dental therapy makes use of prosthetic implant reconstructions, which are supported or retained on implants. The most frequent, long-term complications associated with these implants include mucositis and peri-implantitis. Since is the initial inflammation tissues supporting implant, management this condition thus crucial. aim present study was to assess effects placement bioactive healing abutment for 48 h, in patients diagnosed peri-implant mucositis. Moreover, quantitative...

The study examines how overshoot is influenced by masker-signal onset asynchrony when the masker contains frequencies above or below signal frequency. Masked thresholds were measured for a 2-ms tone at 5kHz. measurements made in reference condition with narrow center-band (CB) noise (4590–5464Hz), and conditions either low-fringe (1900–4590Hz) high-fringe band (5500–11000Hz) added to CB. always came on 2ms after of time interval between fringe onsets varied from −98ms (signal before onset)...
