25. An interneuronal relay for group I and II muscle afferents in the midlumbar segments of the cat spinal cord.
1. The properties of interneurones located in the 4th lumbar segment of the cat spinal cord (L4 interneurones) have been investigated by intracellular and extracellular recording from individual neurones. The study focused on interneurones projecting to hind-limb motor nuclei and/or interposed in pathways from group II muscle afferents. The projection to mot

26. The Kinesin-like Calmodulin Binding Protein Is Differentially Involved in Cell Division
The kinesin-like calmodulin (CaM) binding protein (KCBP), a minus end–directed microtubule motor protein unique to plants, has been implicated in cell division. KCBP is negatively regulated by Ca2+ and CaM, and antibodies raised against the CaM binding region inhibit CaM binding to KCBP in vitro; therefore, these antibodies can be used to activate KCBP con

27. Increased dopamine turnover in the prefrontal cortex impairs spatial working memory performance in rats and monkeys.
The selective activation of the prefrontal cortical dopamine system by mild stress can be mimicked by anxiogenic beta-carbolines such as FG7142. To investigate the functional relevance of elevated levels of dopamine turnover in the prefrontal cortex, the current study examined the effects of FG7142 on the performance of spatial working memory tasks in the ra

28. Gastrointestinal motor mechanisms in hyperglycaemia induced delayed gastric emptying in type I diabetes mellitus.
BACKGROUND: Hyperglycaemia delays gastric emptying, both in healthy controls and in patients with diabetes mellitus. The effect of hyperglycaemia on antroduodenal motility in diabetes has not yet been studied. AIM: To investigate the gastrointestinal motor mechanisms involved in the hyperglycaemia induced retardation of gastric emptying in patients with type

29. The discharge behaviour of single vasoconstrictor motoneurones in human muscle nerves.
1. The discharge behaviour of fourteen single sympathetic vasoconstrictor efferents was studied using a tungsten microelectrode inserted percutaneously into a motor fascicle of the radial or peroneal nerve in eight awake supine subjects. Units were classified as vasoconstrictor because their firing properties correlated appropriately to changes in cardiac in

30. Effect of bran, ispaghula, and inert plastic particles on gastric emptying and small bowel transit in humans: the role of physical factors.
BACKGROUND: Coarse bran is known to accelerate transit through the whole gut and to increase stool weight. This effect is much reduced by grinding the bran, suggesting that particle size influences gut motor patterns. AIMS: To compare the effect of 15 g coarse bran with 15 g inert plastic particles and 7 g of ispaghula on the gastric emptying and small bowel

31. The Antecedents of Schizophrenia: A Review of Birth Cohort Studies
Background: Birth cohort (BC) studies demonstrate that individuals who develop schizophrenia differ from the general population on a range of developmental indices. The aims of this article were to summarize key findings from BC studies in order to identify areas of convergence and to outline areas requiring further research. Method: We define BC studies as

32. Regulation of Microtubule-dependent Recycling at the Trans-Golgi Network by Rab6A and Rab6A'D⃞
The small GTPase rab6A but not the isoform rab6A' has previously been identified as a regulator of the COPI-independent recycling route that carries Golgi-resident proteins and certain toxins from the Golgi to the endoplasmic reticulum (ER). The isoform rab6A' has been implicated in Golgi-to-endosomal recycling. Because rab6A but not A', binds rabkinesin6, t

33. Electrical coupling synchronises spinal motoneuron activity during swimming in hatchling Xenopus tadpoles
The role of electrical coupling between neurons in the swimming rhythm generator of Xenopus embryos has been studied using pharmacological blockade of gap junctions. A conspicuous effect of 18β-glycyrrhetinic acid (18β-GA) and carbenoxolone, which have been shown to block electrical coupling in this preparation, was to increase the duration of ventral root
