PURPOSE To determine the reliability and variability of the Dynamic Strength Index (DSI) calculated from squat-jump (SJ) vs countermovement-jump (CMJ) peak force (PF) and to compare DSI values between methods. METHODS Male youth soccer and rugby league players (N = 27; age 17.2 ± 0.7 y, height 173.9 ± 5.7 cm, body mass 71.1 ± 7.2 kg) performed 3 trials of the SJ, CMJ, and isometric midthigh p...
Presently, the fluvial fluxes of Dissolved silicate (DSi) by many famous rivers in the world have been reported significantly decreased in the past several decades. DSi retention by river damming hence becomes a great concern. In this study, the impact on DSi retention and transport by cascade reservoirs in the Karst area were investigated. Based on the monitoring data for four seasons, budget ...
Depolarization-induced suppression of inhibition (DSI) is a transient reduction of GABAA receptor-mediated IPSCs that is mediated by a retrograde signal from principal cells to interneurons. Using whole-cell recordings, we tested the hypothesis that mGluRs are involved in the DSI process in hippocampal CA1, as has been proposed for cerebellar DSI. Group II mGluR agonists failed to affect either...
Endocannabinoids control hippocampal inhibitory synaptic transmission through activation of presynaptic CB(1) receptors. During depolarization-induced suppression of inhibition (DSI), endocannabinoids are synthesized upon postsynaptic depolarization. The endocannabinoid 2-arachidonoylglycerol (2-AG) may mediate hippocampal DSI. Currently, the best studied pathway for biosynthesis of 2-AG involv...
BACKGROUND The Dysphonia Severity Index (DSI) is an objective multiparametric acoustic calculation of vocal function; however, its changes after thyroidectomy have not yet been described. METHODS Patient-reported symptoms, as well as auditory perceptual, acoustic, and videolaryngostroboscopic (VLS) data, were collected prospectively before and after thyroidectomy. Voice outcomes (normal versu...
We explore the distribution of sponges along dissolved silica (dSi) concentration gradients to test whether sponge assemblages are related to dSi and to assess the validity of fossil sponges as a palaeoecological tool for inferring dSi concentrations of the past oceans. We extracted sponge records from the publically available Global Biodiversity Information Facility (GBIF) database and linked ...
Dual sensory impairment (DSI) refers to the presence of both hearing loss and vision loss. The occurrence of DSI is particularly prevalent among the aging population, with studies showing between 9% and 21% of adults older than 70 years having some degree of DSI. Despite this, there is little direction regarding recommended clinical practice and rehabilitation of individuals with DSI. It is ass...
Depolarization-Induced Suppression of Inhibition (DSI) is effectively a mechanism for feedback-inhibition of inhibition. Wilson and Nicoll [4] showed that its effect is mediated through a retrograde endocannabinoid signal. Here, we produced a simple model for DSI which matched the effects and kinetics of DSI found in empirical data. We then explored a possible function for DSI through examining...
The initiation of protein synthesis in reticulocyte lysates is inhibited by low levels (1-50 ng/ml) of doublestranded RNA (dsRNA) due to the activation of a CAMPindependent protein kinase (dsI) which phosphorylates the a-subunit (38,000 daltons) of eukaryotic initiation factor 2 (eIF-2a). In lysates, dsI is present in an inactive precursor form (latent dsI) associated with the ribosomal complem...
With the increasing aging population, the number of veterans presenting with dual sensory impairment (DSI) (vision and hearing impairments) will increase. This study determined the prevalence and clinical characteristics of DSI in a veteran population receiving healthcare from the Department of Veterans Affairs (VA). A retrospective review was conducted on 400 charts randomly selected from a da...
