Recent evidence, however, would suggest that surface electromyography is not a valid to record activity from other superficially placed shoulder muscles. Therefore, the aim of this study was to determine the validity of using surface electrodes to record lower trapezius activity. Ten asymptomatic subjects performed ramped isometric (0-100% maximum load) and dynamic (70% maximum load) shoulder tasks. Intramuscular electrodes were inserted into lower trapezius and rhomboid major. Surface electrodes were placed over lower trapezius around the intramuscular electrodes. Differences in the recorded activity of lower trapezius between surface and intramuscular electrodes were tested using a 2 factor repeated measures analysis of variance with factors test and electrode type. Similarity in the recorded activity patterns between the two electrodes was tested using Pearson's correlation coefficient (r). Results indicated that there was no difference in lower trapezius activity levels (p = 0.98) or activation patterns (r ≥ 0.74) recorded by the intramuscular and surface electrodes. The results of this study indicate that any potential crosstalk contamination in the surface electrode signal is having little influence on the recorded activity from lower trapezius and therefore, support the common practice of surface electromyography to investigate lower trapezius function.Elevated hearing thresholds in hearing impaired adults are usually compensated by providing amplification through a hearing aid. In spite of restoring hearing sensitivity, difficulties with understanding speech in noisy environments often remain. One main reason is that sensorineural hearing loss not only causes loss of audibility but also other deficits, including peripheral distortion but also central temporal processing deficits. To investigate the neural consequences of hearing impairment in the brain underlying speech-in-noise difficulties, we compared EEG responses to natural speech of 14 hearing impaired adults with those of 14 age-matched normal-hearing adults. We measured neural envelope tracking to sentences and a story masked by different levels of a stationary noise or competing talker. Despite their sensorineural hearing loss, hearing impaired adults showed higher neural envelope tracking of the target than the competing talker, similar to their normal-hearing peers. Furthermore, hearing impairment was related to an additional increase in neural envelope tracking of the target talker, suggesting that hearing impaired adults may have an enhanced sensitivity to envelope modulations or require a larger differential neural tracking of target versus competing talker to segregate speech from noise. Lastly, both normal-hearing and hearing impaired participants showed an increase in neural envelope tracking with increasing speech understanding. Hence, our results open avenues towards new clinical applications, such as neuro-steered prostheses as well as objective and automatic measurements of speech understanding performance.Background The elderly population is growing rapidly worldwide and sarcopenia, which is considered as a new geriatric syndrome has become an important issue. In particular, diabetes is known to be an important risk factor for sarcopenia. In this study, we investigated the effects of Korean Red Ginseng (KRG) on biomarkers of sarcopenia in middle and old age diabetes patients. Patients and methods This study was a randomized, double-blind, placebo-controlled trial. Participants were randomly allocated to either the placebo or KRG group and took corresponding tablets for 24 weeks. The primary outcomes were changes in sarcopenia biomarkers at week 24. Secondary outcomes were changes in inflammatory and antioxidant markers and lean body mass at week 24. Results Fifty-nine patients completed the study. Follistatin and sex hormone binding globulin (SHBG) were significantly improved in KRG group. In the subgroup analysis, female postmenopausal patients over the age of 55 showed a significant improvement in serum SHBG, follistatin, and growth differentiation factor 15 (GDF-15) and an attenuated reduction in Troponin T (TNT) after the administration of KRG. Conclusion Twenty-four week administration of KRG in diabetes patients resulted in a significant improvement in follistatin and SHBG levels, especially in old postmenopausal women. A further, larger population study with a longer follow-up period is warranted to verify and understand the effects of KRG on sarcopenia.Objective This study aimed to determine the effectiveness of three different indices used to identify the effect of visceral adiposity on lipid profile markers in patients with multiple sclerosis. Methods The study consisted of a total of 152 patients with relapsing-remitting multiple sclerosis who were aged 18 years and older. High-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), total cholesterol (TC), and triglyceride (TG) were accessed from the patient system. Patients' height, body weight, waist circumference, and hip circumference measurements were also obtained. The effects of three different adiposity indices, including A Body Shape Index (ABSI), the Body Roundness Index (BRI), and the Visceral Adiposity Index (VAI), on plasma lipid profile in multiple sclerosis patients were evaluated.  https://www.selleckchem.com/Caspase.html  The data were analyzed using the R software and SPSS 21 statistical software package. Results HDL-c was impacted by ABSI and VAI in males and only VAI in females (p less then 0.05). An increase of 0.01 units of ABSI in males led to an increase of 5.88 mg/dL in plasma HDL-c level. In male patients with multiple sclerosis, LDL-c was positively affected by BRI and VAI changes (p less then 0.05). One unit increase in BRI in males increased LDL-c level by 5.56 mg/dL, whereas 1 unit increase in VAI increased LDL-c level by 3.52 mg/dL (p less then 0.05). Conclusion This study indicated that these three different indices employed to evaluate adiposity were associated with plasma lipid profile. The effect of VAI on plasma lipids is higher than that of the other indices. In patients with multiple sclerosis, the use of these practical and non-invasive indices will be useful in assessing plasma lipid profile.
