Head-activator induced mitosis of NH15-CA2 cells requires calcium influx and hyperpolarization [0.03%]
头激活剂诱导NH15-CA2细胞的增殖需要钙离子流入和膜电位超极化
H Ulrich,A Tárnok,H C Schaller
H Ulrich
In NH15-CA2 cells head activator (HA) stimulates cell proliferation by acting in the G2/M transition. Cells in mitosis were analyzed by flow cytometry 2-4 h after HA application. HA in a dose-dependent manner stimulated mitosis. Mitosis was...
NG methyl-L-arginine increases the hyperthermic effects of prostaglandin E1 [0.03%]
NG甲基-L-精氨酸增加前列腺素E1的发热反应
M Monda,A Sullo,E De Luca
M Monda
The sympathetic firing rate of the nerves innervating interscapular brown adipose tissue (IBAT), IBAT and colonic temperatures (TIBAT and TC) were monitored in urethane-anaesthetized male Sprague-Dawley rats. These variables were measured f...
Axonal conduction velocity of motor units of rat's medial gastrocnemius muscle [0.03%]
大鼠腓肠肌内核运动神经元轴突的冲动传导速度研究
J Celichowski,P Krutki,E Bichler
J Celichowski
Axonal conduction velocity and its relations to different contractile properties of motor units of medial gastrocnemius muscle were investigated in nine Wistar rats anaesthetized with pentobarbitone. Functionally isolated motor units were i...
Differences in action of topical and systemic cysteamine on gastric blood flow, gastric acid secretion and gastric ulceration in the rat [0.03%]
卡贝胆碱对大鼠胃血流、胃酸分泌和胃溃疡的作用机制研究
O Abdel-Salam,J Szolcsányi,G Mózsik
O Abdel-Salam
The effect of cysteamine on gastric blood flow and on the indomethacin-induced gastric mucosal damage was studied. In anesthetized rats, cysteamine (280 mg/kg) given subcutaneously (s.c.) decreased gastric blood flow measured by the laser D...
Anteroposterior dynamic balance reactions induced by circular translation of the visual field [0.03%]

A Séverac Cauquil et al.
The anteroposterior sway of subjects under conditions of spontaneous dynamic balance on a wobbly platform was measured during visual stimulation by a visual target executing a circular trajectory in the frontal plane. The target was either ...

Spatio-temporal characteristics of paroxysmal interictal events in human temporal lobe epilepsy [0.03%]
人类颞叶癫痫间歇发作性事件的时空特征
J M Badier,P Chauvel
J M Badier
A spatio-temporal mapping technique was applied to stereotactically-implanted depth electrode recordings (SEEG). This technique was used to study the interictal activity in 13 epileptic patients with temporal lobe epilepsies during the pre-...
Do cortical and thalamic bioelectric oscillations have a functional role? A brief survey and discussion [0.03%]
皮层和丘脑生物电振荡具有功能作用吗？简要综述与讨论
P Buser,A Rougeul-Buser
P Buser
This paper first briefly describes rhythmic bioelectric oscillations that can be recorded from the neocortex (particularly in cats). This descriptive section is followed by a review of the mechanisms whereby these rhythms are generated, and...
Positive feedback as a general mechanism for sustaining rhythmic and non-rhythmic activity [0.03%]
正反馈作为一个维持节律性和非节律性活动的通用机制
A Roberts,R Perrins
A Roberts
Our aim is to reassess our proposal that various states of motor output may be sustained by positive feedback generated within the premotor neural circuitry. The evidence for this proposal came from the Xenopus embryo which when touched can...
Inhibition of crossed caudal interneurons by lateral interneurons in lamprey spinal chord during fictive locomotion [0.03%]
脊髓假想运动中侧向中间神经元对七鳃鳗腹侧中间神经元的抑制作用
J T Davis,L E Moore
J T Davis
Templates of the membrane potential profiles from lateral (LI) interneurons and motoneurons during glutamate- and N-methyl-D-aspartate (NMDA)-induced fictive locomotion showed pronounced plateau phases. In contrast, crossed caudal (CC) inte...

The neuronal network for locomotion in the lamprey spinal cord: evidence for the involvement of commissural interneurons [0.03%]
七鳃鳗脊髓中的运动神经网络：跨侧神经元参与的证据
J T Buchanan,D R McPherson
J T Buchanan
The spinal cord of the lamprey, a primitive vertebrate, has been used as a model system for investigating the cellular basis of rhythmic locomotor activity. Three classes of interneurons have been characterized that are active during locomo...
