The aim of this study was to analyze the influence of a biofeedback relaxation training program on anxiety and academic performance. The program consisted of five biofeedback sessions coupled with three training activities focused on deep breathing, guided imagery, and muscle relaxation. The participants were second-year psychology undergraduates from the University of the Basque Country (UPV/E...

Cognitive control functions decline with increasing age. The present study examines if different types of group-based and trainer-guided training effectively enhance performance of older adults in a task switching task, and how this expected enhancement is reflected in changes of cognitive functions, as measured in electrophysiological brain activity (event-related potentials). One hundred fort...

This article presents current information concerning (a) the structural relationships of the Golgi tendon organ (GTO) with different types of extrafusal muscle fibers; (b) the Gp.Ib reafferent or feedback fibers from the GTO; (c) the way in which these proprioceptors monitor muscle tension and function in parallel processing with other receptors and with the central control mechanisms of the ne...

BACKGROUND Clinical-grade human embryonic stem cells (hESCs) ideally should be derived and maintained in xeno-free culture conditions using defined chemicals or materials of human origin. This will reduce the possibility of xeno-derived pathogenic infection and/or unfavorable immune reaction in clinical application. The present study therefore aimed to derive autogenic feeders from hESCs and ev...

In recent years, EEG-neurofeedback training (EEG-NFB) has been increasingly used to optimize various brain functions. Better performance in various activities was also reported after relaxation trainings, another popular method in therapeutic practice. Both these methods are used as a part of professional coaching in sports training centers. In the present study, we aimed to evaluate the impact...

In a tropical locality of Río La Antigua, Veracruz, Mexico, 11 fish species, represented by 244 individual fish from six freshwater fish families living sympatrically and synchronically, were examined for helminth parasites. A total of 36 taxa of helminths were recorded, 24 autogenic and 12 allogenic forms, including 6 monogeneans, 14 trematodes, 1 cestode, and 15 nematodes. Most helminth taxa ...

In this paper, we highlight new multigrid solver advances in the Terascale Optimal PDE Simulations (TOPS) project in the Scientific Discovery Through Advanced Computing (SciDAC) program. We discuss two new algebraic multigrid (AMG) developments in TOPS: the adaptive smoothed aggregation method (αSA) and a coarse-grid selection algorithm based on compatible relaxation (CR). The αSA method is sho...

Silicon Laboratories' capacitive sensing techniques are compatible with external ESD protection methods. Designers should be aware of parasitic parameters in these circuits which affect capacitive sensing performance when implementing these protection methods. While most of the methods affect sensing performance in some way, in almost all cases an acceptable balance between performance, protect...

BACKGROUND Acceptance-based behavior therapy (ABBT) was developed based on the theory that generalized anxiety disorder (GAD) is maintained through a reactive and fused relationship with internal experiences and a tendency toward experiential avoidance and behavioral restriction. ABBT specifically targets these elements. Here, we aimed to compare ABBT to the applied relaxation (AR), which is th...

Acceptance and commitment therapy (ACT) has a small research base as a treatment for obsessive compulsive disorder (OCD) and related disorders. It is presumed that the process of change in ACT is an increase in psychological flexibility. This study focuses on session by session changes in psychological flexibility in 41 adults diagnosed with OCD who were treated with ACT compared with 38 indivi...
