Force potentiation in the MDX mouse
… fibers. It was hypothesized that post-tetanic potentiation (PTP) would be down-regulated to prevent damage in Xlinked muscular dystrophy (mdx) mice since PTP increases force and PTP effects are greatest in IIB fibers. PTP experiments were performed on the extensor digitorum longus (EDL) of 50 …

Post-Activation Potentiation: Decay or Fatigue Delay
<p>Post-activation potentiation has been shown to improve jumping performance and other ballistic activities. The improvements in performance have been attributed to four main mechanisms, but the most important mechanism to the current study is the improvement in neural activity that leads to …

Serotonergic Circuits Mediating Stress Potentiation of Addiction Risk
… (SERT)-expressing neurons blocked stress-induced potentiation of cocaine conditioned place preference (CPP). Within the dorsal raphe nucleus (DRN), two overlapping populations of KOR-expressing neurons: Slc17a8 (VGluT3) and SERT, were distinguished functionally and anatomically. Optogenetic …

Mechanisms affecting post-activation potentiation following voluntary isokinetic knee extension
… normalised to the muscle compound action potentiation (M-wave) amplitude (EMG:M), was taken as a measure of central drive whereas twitch peak torque and M-wave amplitude were recorded to assess peripheral function. Even after a plateau in voluntary contractile capacity was achieved after …

Role of Cholesterol 24-Hydroxylase in Hippocampal Long-Term Potentiation
… are unable to support the induction of long-term potentiation, a type of synaptic strengthening thought to underlie learning and memory. The ability of 24-hydroxylase knockout slices to exhibit long-term potentiation can be restored by treatment with geranylgeraniol, an isoprenoid end-product of …

Pesticide Mixtures Induce Immunotoxicity: Potentiation of Apoptosis and Oxidative Stress
The three insecticides of interest were lindane (an organochlorine), malathion (an organophosphate) and piperonyl butoxide (PBO; a synergist). Based on minimum cytotoxicity (> LC25), the following concentrations were chosen for the pesticide mixture studies: 70μM lindane (Lind), 50μM malathion …

The induction of long-term potentiation attenuates kainic acid-induced excitotoxicity
… receptors (NMDARs) is required for the long term potentiation (LTP) and long term depression (LTD) of excitatory synaptic transmission at hippocampal CA1 synapses, and plays an important role in learning and memory. In addition, it is accepted that the over-activation of NMDARs leads to the …

Comparison of Post-Activation Potentiation Methods on Power and Sprint Acceleration
<p>Post-activation potentiation (PAP) is a stimulus used to enhance performance by performing specific interventions prior to subsequent explosive movements. The purpose of this study was to determine the effect of different PAP methods on power and sprint acceleration in resistance trained, …

Identification of novel gating mechanisms underlying pharmacological potentiation of NMDA receptors
Excitatory neurotransmission mediated by N-methyl-D-aspartate receptors (NMDARs) is known to play an important role in synaptic plasticity, learning and memory. Moreover, NMDAR dysfunction may contribute to a variety of neuropsychiatric and neurological disorders including schizophrenia, epilepsy, …

스트레스에 의한 Long-term potentiation (LTP)의 저하를 감소시키는 리튬의 효과
PURPOSE: The hippocampus is crucially involved in memory formation which has been known to be highly sensitive to stress. Previous studies have been show that exposure to uncontrollable stress is deleterious to hippocampus-dependent memory formation. Recent studies have demonstrated neuroprotective …

Computational Evaluation and Structure-based Design for Potentiation of Nicotine Vaccines
… report, three separate approaches towards NV potentiation are explored. The first approach applied physiologically-based pharmacokinetic (PBPK) modeling to better assess NV potential. Rat and human physiological and pharmacological parameters were obtained from literature and used to construct …

Priming the Data: Examining Self-Potentiation in a Word Fragment Completion Task
… assessed the presence and severity of self-potentiation effects in a word fragment completion task commonly used to evaluate priming effects. Priming effects have suffered a plethora of replication issues, and the field is currently under intense scrutiny. By analyzing and refining the …

Pesticides and Pesticide Mixtures Induce Neurotoxicity: Potentiation of Apoptosis and Oxidative Stress
Several epidemiological studies have suggested a role for environmental chemicals in the etiology of neurodegenerative diseases such as Parkinson's disease and Alzheimer's disease. Endosulfan (an organochlorine) and zineb (zinc-ethylene-bis-dithiocarbamate) are used as pesticides on a variety of …

Morphological Correlates Of Synaptic Plasticity After Long Term Potentiation In The Rat Hippocampus
… formation after the induction of long-term potentiation (LTP) of the perforant path, although few studies have investigated such parameters in the maintenance phase of L-LTP. Moreover, the results of investigations of synaptic and neuronal morphometry changes after LTP have varied and this …

The application of potentiation in optimizing warm-up procedures in young male athletes
… asserted that all warm-ups should consist of a potentiation phase, over and above a general phase. This potentiation phase should consist of a progressive series of exercises, until maximum effort is achieved. Additionally, Tillin and Bishop, (2009) have suggested that post activation …
