Objective: To investigate the influence of two different electrode montages (ipsilateral: reference to mastoid and vertical: reference to nape of neck) to the ABR results recorded using a level-specific (LS)-CE-Chirp® in normally hearing subjects at multiple intensities levels. Design: Quasi-experimental and repeated measure study designs were applied in this study. Two different stopping criteria were used, (1) a fixed-signal averaging 4000 sweeps and, (2) a minimum quality indicator of Fmp?=?3.1 with a minimum of 800 sweeps. Study sample: Twenty-nine normally hearing adults (18 females, 11 male) participated. Results: Wave V amplitudes were significantly larger in the LS CE-Chirp® recorded from the vertical montage than the ipsilateral montage. Waves I and III amplitudes were significantly larger from the ipsilateral LS CE-Chirp® than from the other montages and stimulus combinations. The differences in the quality of the ABR recording between the vertical and ipsilateral montages were marginal. Conclusions: Overall, the result suggested that the vertical LS CE-Chirp® ABR had a high potential for a threshold-seeking application, because it produced a higher wave V amplitude. The Ipsilateral LS CE-Chirp® ABR, on the other hand, might also have a high potential for the site of lesion application, because it produced larger waves I and III amplitudes. 相似文献

Hair problems can cause considerable anxiety to both children and their parents. This article discusses hair growth and cycling, the common presentations of hair loss in infancy and childhood and an approach to diagnosis. This information will help equip the reader to manage common types of hair loss in the paediatric setting. 相似文献

A functionalized exfoliated graphite rod (FEGR), with a high surface area, is produced for use as a promising substrate for supercapacitors, via controlled oxidative treatment of a recycled graphite rod of exhausted zinc–carbon batteries. SEM, EDX, XPS, FT-IR, Raman, and contact angle measurements are carried out to disclose the surface characteristics of the FEGR. The surface of the FEGR is characterized by in situ generated grooves, together with graphene layers which are directly attached to the underlying graphite base. The FEGR electrodes enhance the capacitive performance of Ni(OH)2 and binary Ni–Co(OH)2. The Ni–Co(OH)2/FEGR electrode displays a superb specific capacity value (2552.6 C g−1) at a current density of 5 A g−1 and this value is retained to 70.8% at a high current density of 50 A g−1 indicating the outstanding rate performance of this electrode material. This enhanced behavior is attributed to the facile interaction of electrolyte species, even at high current density, with the active sites of the redox catalyst layer (distributed over a larger fraction of the underlying substrate with enhanced hydrophilicity). Moreover, the excellent electrical conductivity of the in situ surface generated graphene layers is another promoting factor.A functionalized exfoliated graphite rod (FEGR), with a high surface area, is produced for use as a promising substrate for supercapacitors, via controlled oxidative treatment of a recycled graphite rod of exhausted zinc–carbon batteries. 相似文献

Aim of the workTo evaluate audiological characteristics in rheumatoid arthritis (RA) patients compared with controls using extended high frequency audiometry and analyze their correlations with RA activity and severity to identify patients at higher risk of hearing loss.Patients and methodsThe study was carried out on 95 RA patients and 100 controls. Every subject underwent pure tone audiometry (PTA) from 250 through 8000 Hz, speech audiometry and extended high frequency audiometry (EHFA) from 10,000 to 20000 Hz. Disease activity score (DAS28) and RA medical records-based index of severity (RARBIS) were assessed.ResultsPatients were 85 females and 10 males with age mean 46.5 ± 1.1 years and disease duration of 9.57 ± 0.61 years. The hearing thresholds (HT) of patients were significantly higher than those of controls at all PTA (p < 0.001) and EHFA frequencies (p < 0.001). Hearing loss (HL) was detected in 68.4% and 64.2% by using PTA, while EHFA revealed it in 100% and 97.9% of right and left ears of RA patients respectively. Hearing loss was bilateral, symmetrical and sensorineural in all cases. HT of EHFA significantly correlated with age (r = 0.63, p < 0.001), age at onset (r = 0.51, p < 0.001), disease duration (r = 0.3, p = 0.03), DAS28 (r = 0.31, p = 0.01) and RARBIS (r = 0.21, p = 0.03).ConclusionBilateral symmetrical sensorineural hearing loss (SNHL) is significantly more frequent in RA patients compared to control. EHFA is valuable test to detect HL in patients with RA. Older age, longer disease duration, higher disease activity and severity are important factors for the development of HL in RA. 相似文献

Acrylamide (ACRL) was demonstrated to induce hepatotoxicity and programmed cell death (PCD). Rapamycin (RAPA)-induced autophagy had been reported to limit the progression of hepatocellular injury in experimental models. This research was designed to study two death pathways involved in ACRL-induced hepatotoxicity and the modulating effect of RAPA on the resulting hepatic injury. Thirty-six adult male rats were divided into three groups: control group, ACRL-treated group (20 mg kg/day), and the last group co-treated with ACRL plus RAPA (0.5 mg kg/day). Drugs were administered for 21 days via oral gavage. Blood samples were collected to assess alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Livers were dissected; parts were used for detection of superoxide dismutase (SOD) and malondialdehyde (MDA) tissue levels. Other parts were processed for hematoxylin and eosin, Masson's trichrome staining, immunostaining for microtubule-associated proteins 1A/1B light chain 3B (LC3), ubiquitin-binding protein (p62), caspase-3, and receptor-interacting protein kinase 1 (RIPK1). ACRL induced a significant elevation in ALT, AST, MDA levels, and reduction in the SOD level. ACRL also induced hepatocellular injury, fibrosis, and defective autophagy indicated by elevation of LC3 and p62 and increased p62/LC3 ratio. Moreover, it increased the apoptotic (caspase-3) and necroptotic (RIPK1) markers expression. RAPA significantly reduced liver enzymes, oxidative stress, fibrosis, and improved liver histology. Moreover, RAPA decreased p62/LC3 ratio indicated enhanced autophagy, and significantly reduced caspase-3 and RIPK1 expression. In conclusion, RAPA maintained autophagic activity which may save the hepatocytes from PCD and enhance cell viability. 相似文献

Aim of the work
To compare the D-dimer status in children with familial Mediterranean fever (FMF) during, and in between acute attacks.Patients and methods
The study included 50 children with FMF classified into group I (15 patients during acute attack) and group II (35 patients during attack free period) as well as and 20 matched controls. D-dimer was determined in all study population. Pattern and type of FMF gene mutation were reported from patients’ files.Results
The mean age of the patients was 8.7 ± 2.8 years, disease duration 4.4 ± 2.5 years and they were 28 males:22 females (1.3:1). In group I, the erythrocyte sedimentation rate (48.5 ± 28.6 mm/1st h) and aspartate transaminase (28.5 ± 5 U/L) were significantly increased compared to group II (26.6 ± 14.7 mm/1st h and 25.7 ± 2.7 U/L; p = 0.012 and p = 0.014 respectively). Positive D-dimer was significantly reported in 72% of FMF patients compared with 35% of control (p = 0.006). There was significant difference between frequency of positive D-dimer in group I (86.7%) and group II (65.7%) compared to (35%) in control (p = 0.005 and p = 0.048, respectively), without a significant difference in D-dimer frequency between group I and group II patients (p = 0.18). Fever and abdominal pain were significantly more frequent in patients with positive (100% and 97.2%) compared to negative D-dimer (78.6% and 71.4%) (p = 0.02). No significant association was found between positive D-dimer and specific types of MEFV gene mutation.Conclusion
D-dimer was significantly positive in FMF patients compared to control. These results raise the possibility of thrombosis in FMF patients regardless the presence or absence of acute attack. 相似文献1000.
