Return Pressure Alarm This is a warning alarm. It occurs when there is an occlusion or something impeding the flow of blood to the patient. Possible causes are displayed on the screen along with suggestive intervention. If return pressure is too high, first of all ensure the line is not rapped, clamped or kinked. Then to relieve excess pressure either manually turn the effluent pump anti-clockwise counter clockwise ; or pull out on the return line clamp. Once return pressure decreases press "continue". Access Disconnection This also is a warning, alarm occurs when the access line is disconnected from the catheter or there is an occlusion below the pressure pod on the machine. It is possible to override this alarm for 60 seconds in order to maintain blood flow but the cause of the alarm must be remedied. The screen will show other possible causes. Air in Blood This is also an Alarm. It can occur if there is air in the return line during treatment. The screen will show the alarm screen and suggestive intervention will be displayed. Follow the instructions closely and press "continue" once all air is removed. If there is a micro-air in blood alarm and there is no air that you can visibly see, this alarm can be overridden but the machine will alarm again within 60 seconds if there is too much air present. If this is the case then follow the instructions for air removal and press "continue". Diaphragm Repositioning Procedure Perform this procedure if the Prisma detects a defective pod or if a pressure pod is accidentally removed after priming is complete. The normal position of the diaphragm is in the centre of the pod but if the diaphragm is moved and remains positioned too far towards the back or front of the pod, pressure within the extracorporeal circuit can no longer be accurately detected. If this procedure is required you will be notified by the machine via an alarm screen to perform a diaphragm repositioning procedure, which moves the position of the diaphragm back to the centre of the pod. When performing this procedure, the affected pod and the sample site closest to the pod are isolated from the rest of the extracorporeal circuit using tow clamps. The instructions for this procedure are displayed on the screen. Follow them closely. Manual Termination of Treatment The patient's treatment can be terminated manually at any time. Manual termination may be required due to an alarm, power failure or other emergency. 1. Turn the power off to the machine and then clamp and disconnect the access line from the patient. Attach the access line to a 500ml bag of sodium chloride 0.9%. 2. Remove the return line from the return clamp which is always clamped when the power is off ; . 3. Manually turn the blood pump anti-clockwise until sufficient blood is returned to the patient. Since the power is off the alarm system will be disabled. It is important to observe for air in the return line until the patient is disconnected. 4. Clamp the return line and disconnect from the patient. Clamp lines to all bags. 5. Press the clip of the cartridge carrier left side ; to release the cartridge. Starting with any peristaltic pump, manually turn each pump anti-clockwise.

Ulate these genes. Fourth, the three nAChR antagonists alone were able to alter the expression of some of the genes identified see Tables IIIV for a summary of results ; . Although there is a formal possibility that antagonists could be affecting ongoing non-nAChR signaling that modulates gene expression, this result implies that there exists a nAChR-dependent pathway to repress gene expression that is independent of nAChR channel opening. The assessment in this study of effects of nAChR antagonists alone should be, but is not, routine practice. Many studies showing the effects of antagonist plus agonist treatments, such as blockade of or failure to block nicotinic agonist effects and synergy with nicotinic agonist effects, need to be replicated with concomitant assessments of antagonist effects alone to help elucidate the bases for ligand actions. Had our studies not examined the effects of antagonists alone, interpretation of the results would have been misleadingly simplified. What Are the Signaling Pathways Leading from nAChR Activation to Altered Gene Expression?--Our data suggest that at least two initial nAChR-mediated signals can modulate gene expression. Although d-TC blocked the majority of the effects of nicotine on gene expression, the levels of several mRNAs were affected by d-TC alone, and this effect was not reversed when nicotine and d-TC were used in conjunction. For DHFR, d-TC repressed expression comparably to nicotine. For contactin 1, matrin3, and UBE3A, d-TC elicited an increase in mRNA levels, whereas nicotine reduced mRNA levels. Additionally, -cobratoxin and mecamylamine alone affected the expression of multiple genes. These observations suggest several possibilities. First, there may be at least two nAChR-dependent signaling pathways. One pathway may be dependent on channel opening and subsequent ion flow, and a second pathway may be activated by changes in nAChR conformation that result from either agonist or antagonist binding. In support of the first possibility, 7-nAChR are highly permeable to calcium, and in the SH-SY5Y cell, activation of 7-nAChR has been shown to activate the extracellular signal-regulated kinase 1 2 through a calcium-dependent mechanism 16 ; . Nicotine has been shown to activate this pathway, which ultimately affects gene expression. In contrast, the observation that antagonists alone can significantly repress expression of some genes supports the view that alternative conformational states of the nAChR can affect the expression of some genes. Previous studies have not determined the effects of nAChR antagonists on activation of the MAPK pathway. It is therefore unclear whether mecamylamine, d-TC, or -cobratoxin could activate the MAPK signaling pathway, thereby possibly explaining their effects on gene expression through a common signaling pathway. Could Changes in Contactin 1 mRNA Levels Be Involved in Nicotine-induced nAChR Up-regulation?--One of the interesting aspects of nAChR function is the phenomenon of up-regulation. When SH-SY5Y cells are continuously exposed to nicotine, there is an early transient decrease in the total number of assembled, cell surface nAChR that display radioligand binding. However, numbers of total radioligand-binding sites increase immediately, reflecting an increase in intracellular pools 22 ; . Over time, the decline in surface receptor numbers reverses, perhaps reflecting renewal and then later up-regulation of cell surface pools replenished from the increased intracellular pool of precursors. The mechanisms underlying this response are poorly understood. Nicotine treatment significantly reduced the expression of the contactin 1 mRNA in as little as 1 h Tables I and II and Fig. 2 ; . Contactin physically interacts with many different proteins on the cell surface, including voltage-gated Na channels 26, 27 ; , protein-tyrosine phosphatase receptors 25, 47 49.

Vitamin E and Cancer Prevention KIMBERLY KLINE, WEIPING YU, AND BOB G. SANDERS, Division of Nutrition and School of Biological Sciences, University of Texas at Austin, Austin, TX 78712 Is Vitamin E's Superstar Status Warranted? Analyses of data from the 19992000 National Health and Nutrition Examination Survey, estimate that approximately 12% of U.S. adults 24 million people ; consume 400 IU or more of vitamin E daily from supplements 1 ; . Unfortunately, recent evidence from several randomized, double-blind, controlled trials cast doubt on the ability of vitamin E supplementation to reduce risk for cancer, cardiovascular disease, or Alzheimer disease 2 ; . Of major interest will be the outcome of SELECT Selenium and Vitamin E Cancer Prevention Trial ; , a clinical trial to see if either selenium 200 g day Lselenomethionine ; or vitamin E 400 IU day all-rac tocopheryl acetate ; singly or in combination will prevent prostate cancer 3 ; . The rationale for this trial is largely based on secondary analysis of the large, randomized, controlled ATBC Alpha Tocopherol Beta Carotene ; Study which showed that participants taking vitamin E 50 mg day all-rac tocopheryl acetate ; had 32% fewer cases of prostate cancer, 41% fewer deaths from prostate cancer, and a 50% increase in death from hemorrhagic strokes 3 ; . How Many Forms of Vitamin E Are There? One thing that hampers the understanding of vitamin E by both lay people and scientists is that vitamin E comes in multiple naturally occurring forms in the diet with varying levels of bioavailability and biological activity as well as different mechanisms of action. Furthermore, unlike other vitamins the synthetic form of vitamin E which is used in fortified foods and multivitamins is not equivalent in either chemical structure or bioactivity to the form of vitamin E recognized as the most biologically available form; namely, naturally occurring RRR- tocopherol. The synthetic form, properly referred to as all-rac tocopherol but also frequently called dl tocopherol, is a mixture of 8 steroisomers, only one of which is RRR tocopherol. Many studies simply state that they use alphatocopherol, failing to distinguish between using the natural RRR- or synthetic all-racform.

DISCUSSION We have cloned and functionally identified a GABA transporter from C. elegans. The transporter is a member of the sodium-dependent neurotransmitter symporter snf ; family identified in this organism. The cloned transporter is snf-11 and functions as a Na Cl coupled transporter for the neurotransmitter GABA. It exhibits high affinity for GABA Kt, ~15 M ; and is highly selective for GABA. The only other structurally related compound with ability to interact with the transporter to a significant extent is -aminobutyric acid. Other neurotransmitters neuromodulators such as taurine, glycine, and glutamate do not interact with the transporter. The function of this transporter is demonstrable in two different heterologous expression systems: expression in mammalian cells as well as in X. laevis oocytes. The transport process exhibits a Na + Cl-: GABA stoichiometry of 2: 1: and is electrogenic. Since this is the first GABA transporter identified at the molecular and functional levels in C. elegans, we named this transporter ceGAT-1. Mammals express four different GABA transporters, known as GAT-1, GAT-2, GAT-3, and BGT-1 GAT-4 6, 7 ; . Based on the functional characteristics and expression pattern, the cloned ceGAT-1 is distinct from BGT-1 GAT-4 because ceGAT-1 does not interact with betaine. While ceGAT-1 is expressed exclusively in GABAergic neurons, there is no overlap between markers of GABAergic neurons and BGT-1 GAT-4 in mammalian brain 6, 7 ; . Furthermore, we have cloned snf-3, another member of snf family from C. elegans, which we have shown to function as a Na Cl coupled transporter for betaine G. Jiang, Y. J. Fei, and V. Ganapathy, unpublished data ; . Whether C. elegans expresses additional GABA transporters is not known at present. We have cloned three other members of the C. elegans snf family snf-5, snf-6, and snf12 ; and functional analysis with heterologous expression in mammalian cells has shown that none of these possesses the ability to transport GABA G. Jiang, Y. J. Fei, and V. Ganapathy, unpublished data ; . Nonetheless, since ceGAT-1 is selectively associated with GABAergic neurons, we postulate that this transporter is likely to be the C. elegans ortholog of either GAT-1 or GAT-3 in mammals. GAT-1 and GAT-3 are closely associated with GABAergic neurons in mammalian brain. The identification of GAT-1 in C. elegans suggests that the role of the transporter in the modulation of GABAergic neurotransmission is likely to be similar to that of GAT-1 and or GAT-3 in mammalian GABAergic neurons. The functional characteristics of ceGAT-1 in that it is a Cl coupled, high affinity, and selective transporter for GABA support the hypothesis that the transporter functions in the clearance of GABA from the synaptic cleft or motor endplate. These findings are of significance with respect to the biology of GABAergic neurotransmission in C. elegans. Previous studies have identified at the molecular and functional levels the enzyme responsible for GABA synthesis unc-25 ; , the transporter responsible for packaging GABA in synaptic vesicles unc-47 ; , and the receptor responsible for the transmission of GABA signals unc-49 ; 15 ; , but there are no reports in the literature on the molecular and functional identity of any transporter that is responsible for the clearance of GABA from the synaptic cleft or motor endplate. Thus, the findings presented in this paper fill an important gap in our knowledge in terms of GABAergic neurotransmission in this organism. Even though all of the currently known GABA transporters in mammals have been cloned and functionally characterized several years ago, there are no reports to date in the literature on the generation of knock-out animal models for any of these transporters. There is.

Synaptic release of dopamine in the nucleus accumbens of the intact rat brain elicited by a single electrical impulse applied to ascending dopaminergic fibers results in extracellular concentrations sufficient to bind the known dopamine receptors. The dopamine concentration observed after four rapid, sequential pulses is exactly four times greater and is unaffected by pharmacological antagonism of dopamine uptake and receptor sites at supramaximal concentrations. Thus, dopamine efflux from the synaptic cleft is not restricted by binding to intrasynaptic proteins on the time scale of the measurements 50-l 00 msec ; . The extracellular concentration, as a result of a single stimulus pulse, is 0.25 I and is rapidly removed by extrasynaptic uptake. This maximal, transient concentration of dopamine is 60 times higher than steady-state concentrations reported previously using dialysis techniques, illustrating that dopamine extracellular concentrations are spatially and temporally heterogenous. In contrast to ACh transmission at the neuromuscular junction, the dopamine synapse in the telencephalon is designed for the effective efflux of dopamine from the synaptic cleft to the extrasynaptic compartment during neurotransmission.
