(1) This modulation results from repetitive, alternating bursts of excitatory and inhibitory postsynaptic potentials, which are caused at least in part by synaptic feedback to the command neurons from identified classes of neurons in the feeding network.
(2) Pokeweed mitogen-stimulated rat spleen cells were identified as a reliable source of rat burst-promoting activity (PBA), which permitted development of a reproducible assay for rat bone marrow erythroid burst-forming units (BFU-E).
(3) PMNs could be primed for PMA-triggered oxidative burst by muramyl peptide molecules (MDP) and two of its adjuvant active nonpyrogenic derivatives.
(4) For each temporal position of the independent noise, discriminability was a function of the ratio of the duration of the independent noise (tau) to the total burst duration.
(5) Peripheral blood monocytes undergo an oxidative burst similar to that seen in neutrophils.
(6) The 20-year-old now holds two world records after he broke the 50m best at the European Championships in Berlin during a 2014 season which saw him burst on to the international stage.
(7) Masking experiments are demonstrated for electrical frequency-modulated tone bursts from 1,000 to 10,000 cps and from 10,000 to 1,000 cps with superimposed clicks.
(8) Isolated outer hair cells from the organ of Corti of the guinea pig have been shown to change length in response to a mechanical stimulus in the form of a tone burst at a fixed frequency of 200 Hz (Canlon et al., 1988).
(9) Moreover, the most recent combined application of the rat interstitial cell testosterone (RICT) bioassay and a novel multiple-parameter deonvolution model has allowed investigators to dissect plasma concentration profiles of bioactive LH into defined secretory bursts, which have numerically explicit amplitudes, locations in time, and durations, and are acted upon by determinable subject- and study-specific endogenous metabolic clearance rates.
(10) By this action, oxytocin is believed to increase the probability of successful regenerative spikes and thereby initiate electrical activity in quiescent preparations, increase the frequency of burst discharges, the number of spikes in each burst, and the amplitude of spikes in individual cells.
(11) When we gave her a gift of a few books in English, she burst out crying.
(12) Our hypothesis is that phase unlocking may be one of the induction mechanisms of spike-burst activity.
(13) As the frequency of the stimulus bursts was progressively changed, the sinoatrial (SA) nodal pacemaker cells became synchronized with the repetitive bursts of stimuli over a certain range of burst frequencies.
(14) Respiratory burst activity was evaluated in monolayers of rat inflammatory peritoneal macrophages by measuring: (1) luminol-dependent chemiluminescence and (2) the production of 14CO2 from the oxidation of [1-14C] glucose.
(15) After more than 10 weeks, CD34+, CD33- cells gradually recovered, as erythroid burst colony-forming cells increased following GM colony-forming cells.
(16) It is suggested that during increased levels of extracellular adenosine the response of LGND relay neurones to activating brainstem influences will be depressed, and a pattern of Ca(2+)-mediated burst firing will be favoured.
(17) Polygraphic and videotape recordings, carried out for several nights, showed that after nearly each REM period, he would wake up briefly, presenting eye blinking followed by a burst of generalized hypersynchronous theta to start his seizures.
(18) To test this hypothesis 30 Wistar rats were subjected to laparotomy and colonic resection and treated with 5-Fluorouracil or Mitomycin C. The bursting strength of the abdominal scars and the colonic anastomotic bursting pressure revealed some interference in the rats treated with 5-Fluorouracil (Student's t test P less than 0.05) but none in the case of Mitomycin C. This preliminary study deserves to be followed up.
(19) For now however, what’s left of their fan base are enjoying a rare burst of sunshine.
(20) Similar responses were obtained with gated noise bursts and by pauses in a series of clicks.
