Background: Patients with mitral valve prolapse (MVP) may be prone to ventricular arrhythmias and sudden cardiac death and presence early repolarization pattern (ERP) in electrocardiography may be predict for ventricle arrhythmia. This study aimed to evaluation ERP in Children with MVP.
Methods: In a cross-sectional study, we enrolled ERP in 70 MVP children with 70 age-and sex-matched healthy individuals. After echocardiography procedure for confirmation MVP, standard 12-lead electrocardiography recordings with sweeping rate of 25mm/s and an amplitude of 10mV/cm, and two cardiologists assessed who were blinded to the both groups.
Result: We detected ERP in 17.14% of MVP patient's and seen in 8 case (11.43%) in control group, (P=0.23). the ERP occurred in MVP patient's mild, moderate and severe 4, 6 and 2 cases, (P=0.29). The ERP found in patients with and without chest pain 13 and 7, respectively (P=0.46) and, in patients with and without palpitations 15 and 5 cases, respectively (P=0.24). The ERP occurred 1.6 time more in patient with MVP in comparing with individual without MVP. The ERP occurred more frequently in among patients with moderate MVP in comparing with severe and mild. Chest pain and palpitation occurred more frequently in among patients with severe MVP.
Conclusion: The prevalence of ERP in children with MVP has been at a higher-level incidence, especially among patients with complaining from chest pain. We suggested that children with MVP are in need of follow up considering the occurrence of arrhythmias.

Aim: To establish an animal model of form deprivation amblyopia based on a simulated cataract intraocular lens (IOLs).
Methods: Poly(dimethyl siloxane)-SiO thin films (PSF) with different degrees of opacity as IOL materials were prepared. The light transmission of the PSF-IOL was measured, and its biosafety was determined by cell counting kit (CCK)-8 assay using the HLEC-B3 cell line and ARPE-19 cell line.

Background: The androgen receptor pathway inhibitors (ARPI), abiraterone acetate and enzalutamide, are commonly used in first-line treatment of patients with metastatic castration-resistant prostate cancer (mCRPC). However, early resistance to ARPI treatment occurs frequently. Traditionally, the response is evaluated 3-6 months after the start of treatment.

High frequency repetitive transcranial magnetic stimulation (rTMS) to the posterior-superior insula (PSI) may produce analgesic effects. However, the alterations in cortical activity during PSI-rTMS analgesia remain poorly understood. The present study aimed to determine whether tonic capsaicin-induced pain and cortical inhibition (indexed using TMS-electroencephalography) are modulated by PSI-rTMS.

Although the effects of emotionality on word processing might be modulated by lexical category, a body of extant literature has tended to obviate the need of considering this factor. In this study, we attempted to address how lexical category modulates the effects of emotionality on L2 word processing. To this end, event-related potentials (ERPs) were recorded from a group of late proficient Chinese-English bilinguals while they performed a lexical decision task with a set of tightly matched negative, positive, and neutral words across three lexical categories (nouns, verbs, adjectives).

Purpose: Tethered cord syndrome (TCS) typically presents with urologic symptoms and abnormal imaging findings. However, some patients present with normal conus medullaris level and filum terminale appearance on MRI. This research seeks to assess the intended surgical results in this particular group of TCS patients who do not present with urologic complaints, under the premise that the surgical approach goes a long way in preventing the onset of urologic abnormalities.
