corticotropinreleasing factor crf is one of the principle components of the AS response the physiological effects of crf are mediated by two receptor subtypes crf and crf recent data obtained with the selective crf antagonist antisauvagine asv has begun to suggest that both CRF-R subtypes may play a role in stressrelated behaviors exactly how these two receptor subtypes interact to modulate the behavioral and endocrine responses to AS is not clear however we have attempted to understand the role of the CRF-R in the behavioral and endocrine responses to AS by comparing the effects of asv with the mixed crfcrf receptor antagonist astressin centrally administered asv reduced anxietylike SMB in balbc mice in three models of anxiety marble burying MED med nmol open field med nmol and elevated plus maze med nmol asv did not change locomotor activity or the ACTH hormone acth response to restraint AS the potent mixed crfcrf antagonist astressin not only reduced ALB in all three models with equivalent potency but also blunted the acth response to restraint AS finally the new selective CRF-R agonist urocortinii produced a dosedependent increase in ALB in the plus maze test therefore our data suggest that the crf receptor plays a role in the behavioral but not the hypothalamicpituitaryadrenal axis response to AS

voltagegated sodium channels maintain the electrical cadence and stability of SN and muscle cells by selectively controlling the TM passage of their namesake ion the degree to which these channels contribute to cellular excitability can be managed therapeutically or finetuned by endogenous ligands intracellular calcium for instance modulates sodium channel inactivation the process by which sodium conductance is negatively regulated we explored the molecular basis for this effect by investigating the interaction between the ubiquitous calcium binding protein calmodulin cam and the putative sodium channel inactivation gate composed of the cytosolic linker between homologous channel domains iii and iv diiiiv experiments using isothermal titration calorimetry show that cam binds to a novel double IMT motif in the center of the diiiiv linker in a calciumdependent manner NT to a region previously reported to be a cam binding site an alanine scan of aromatic residues in recombinant diiidiv linker peptides shows that whereas multiple side chains contribute to cam binding two tyrosines tyr and tyr play a crucial role in IB the cam clobe the PET relevance of these observations was then ascertained through EP measurement of sodium channel inactivation gating in the presence and absence of calcium experiments on patchclamped transfected tsa cells show that only the ya mutation of the five sites tested renders sodium channel steadystate inactivation insensitive to cytosolic calcium the results demonstrate that calciumdependent calmodulin IB to the sodium channel inactivation gate double IMT motif is required for calcium regulation of the cardiac sodium channel

type diabetes td is an autoimmune disease in which the clinical onset most frequently presents in adolescents who are genetically predisposed there is accumulating evidence that the endocrine pancreas has regenerative properties that hematopoietic chimerism can abrogate destruction of beta cells in autoimmune diabetes and that in this manner physiologically sufficient endogenous insulin production can be restored in clinically diabetic nod mice recapitulating what also has been seen sporadically in humans we set out to test reliable and clinically translatable alternatives able to achieve these same goals recently tian and colleagues demonstrated that td can be prevented in genetically susceptible mice by substituting a diabetessusceptible class ii mhc beta chain with a diabetesresistant allelic Tg on their hematopoietic stem cells through gene supplantation the expression of the newly formed diabetesresistant molecule in the reinfused hematopoietic cells was sufficient to prevent td ON even in the presence of the native diabetogenic molecule if this approach to obtain autoimmunity abrogation could facilitate a possible recovery of autologous insulin production in diabetic patients safe induction of an autoimmunityfree status might become a new promising therapy for td

laserinduced acoustic desorption liad from thin metal foils is a promising technique for gentle and efficient volatilization of IN organic molecules from surfaces of solid substrates using the singlephoton ionization method combined with timeofflight mass spectrometry we have examined the neutral component of the desorbed flux in liad and compared it to that from direct laser desorption these basic studies of liad conducted for molecules of various organic dyes rhodamine b fluorescein ANT coumarin bbq have demonstrated detection of intact parent molecules of the analyte even at its surface concentrations corresponding to a submonolayer coating in some cases RB fluorescein bbq the parent molecular ion peak was accompanied by a few fragmentation peaks of comparable intensity whereas for others only peaks corresponding to IN parent molecules were detected at all measured desorbing laser intensities from to mwcm the total amount of desorbed parent molecules depended exponentially on the laser intensity translational E/A of the desorbed intact molecules determined for the first time in this work were of the order of hundreds of meters per second less than what has been observed in our experiments for direct laser desorption but substantially greater than the possible perpendicular velocity of the ATP foil surface due to lasergenerated acoustic waves moreover these velocities did not depend on the desorbing laser intensity which implies the presence of a more sophisticated mechanism of SE transfer than direct mechanical or thermal coupling between the laser PP and the adsorbed molecules also the total flux of desorbed IN molecules as a function of the total number of desorbing laser pulses striking the same point on the target decayed following a power law rather than an exponential CF as would have been predicted by the shakeoff MM to summarize the results of our experiments indicate that the liad phenomenon cannot be described in terms of simple mechanical shakeoff or direct laser desorption rather they suggest that multistep energytransfer processes are involved two possible and not mutually exclusive qualitative mechanisms of liad that are based on formation of nonequilibrium energy states in the adsorbatesubstrate system are proposed and discussed

the goal of this study was to investigate morphological adaptations associated with hydrostatic elongation of the tongue during FF in the african pignosed frog hemisus marmoratum whereas previous studies had suggested that the tongue of h marmoratum elongates hydraulically the anatomical observations reported here favour a muscular hydrostatic mechanism of tongue elongation h marmoratum possesses a previously undescribed compartment of the m GG m GG dorsoventralis which is intrinsic to the tongue and whose muscle MF are oriented perpendicular to the long axis of the tongue on the basis of the arrangement and orientation of muscle fibres in the m GG and m hyoglossus we propose a muscular hydrostatic model of tongue movement in which contraction of the m genioglossus dorsoventralis together with unfolding of the intrinsic musculature of the tongue results in a doubling in tongue length electron micrographs of sarcomeres from resting and elongated tongues show that no special adaptations of the sarcomeres are necessary to accommodate the observed doubling in tongue length during feeding rather the sarcomeres of the m genioglossus longitudinalis are strikingly similar to those of anuran limb muscles the ability to elongate the tongue hydrostatically conferred by the presence of the m genioglossus dorsoventralis is associated with the appearance of several novel aspects of feeding behaviour in h marmoratum these include the ability to protract the tongue slowly thereby increasing capture success and the ability to aim the tongue in azimuth and elevation relative to the head compared with other frogs the muscular hydrostatic system of h marmoratum allows more precise localized and diverse tongue movements this may explain why the m genioglossus of h marmoratum is composed of a larger number of motor units than that of other frogs

we show that nonlinear inertial coupling between a linear oscillator and an eccentric rotator can lead to very interesting interchanges between regular and chaotic dynamical behavior indeed we show that this MM demonstrates rather unusual behavior from the viewpoint of nonlinear dynamics specifically at a discrete set of values of the TE the hamiltonian system exhibits nonconventional nonlinear normal modes whose shape is determined by phase locking of rotatory and oscillatory motions of the rotator at integer ratios of characteristic frequencies considering the weakly damped system resonance capture of the dynamics into the vicinity of these modes brings about regular motion of the system for SE levels far from these discrete values the motion of the system is chaotic thus the succession of resonance captures and escapes by a discrete set of the normal modes causes a CS of EMT between regular and chaotic SMB provided that the damping is sufficiently small we begin from the hamiltonian system and present a series of poincaré sections manifesting the complex structure of the phase space of the considered system with inertial nonlinear coupling then an approximate analytical description is presented for the nonconventional nonlinear normal modes we confirm the analytical results by numerical simulation and demonstrate the alternate transitions between regular and chaotic dynamics mentioned above the origin of the chaotic behavior is also discussed

previous studies performed in jaw muscles of rabbits and rats have demonstrated that sympathetic outflow may affect the activity of muscle spindle afferents msas the resulting impairment of msa information has been suggested to be involved in the genesis and spread of chronic muscle pain the present T0 was designed to investigate sympathetic influences on muscle spindles in feline trapezius and splenius muscles trsp as these muscles are commonly affected by chronic pain in humans experiments were carried out in cats anesthetized with alphachloralose the effect of electrical stimulation hz for s or hz for min of the peripheral stump of the cervical sympathetic nerve csn was investigated on the discharge of trsp msas units classified as ialike and iilike and on their responses to sinusoidal stretching of these muscles in some of the experiments the local microcirculation of the muscles was monitored by LDF in total msas were recorded stimulation of the csn at hz powerfully depressed the mean discharge rate of the majority of the tested msas and also affected the sensitivity of msas to sinusoidal changes of muscle length which were evaluated in terms of amplitude and phase of the sinusoidal fitting of unitary activity the amplitude was significantly reduced in ialike units and variably affected in iilike units while in general the phase was affected little and not changed significantly in either group the discharge of a smaller percentage of tested units was also modulated by hz csn stimulation blockade of the NM junctions by pancuronium did not induce any changes in msa responses to csn stimulation showing that these responses were not secondary to changes in extrafusal or fusimotor activity further data showed that the sympathetically induced modulation of msa discharge was not secondary to the concomitant reduction of muscle blood flow induced by the stimulation hence changes in sympathetic outflow can modulate the afferent signals from muscle spindles through an action exerted directly on the spindles independent of changes in blood flow it is suggested that such an action may be one of the mechanisms mediating the ON of chronic muscle pain in these muscles in humans

the cmyc oncoprotein is a transcription factor involved in cellular transformation we previously found m v blagosklonny et al cancer res that exposure of human skbr breast cancer and lncap prostate CA cells to otetradecanoylphorbolacetate tpa led to a growth arrest associated with the upregulation of the cyclindependent kinase inhibitor pwafcip and the inhibition of cmyc expression we show here that exogenous cmyc inhibits p expression in skbr and lncap cells induced to enter into sphase p expression was not increased from basal levels in tpatreated growtharrested cells a time course T3 infection of tpaarrested cells using a cmycexpressing adenovirus revealed that the inhibition of p expression preceded entry into sphase in contrast T3 infection by efexpressing adenovirus p expression was reduced after the cells entered sphase overexpression of cmyc reduced the levels of endogenous p mrna and transfection of cmyc repressed ppromoter luciferasereporter gene expression the results suggest that the downregulation of p expression may contribute to cmycdependent entry into sphase possibly in situations in which growth arrest is associated with increased p expression

here we report a detailed procedure for the exact quantification of minute amounts of nucleic acids by competitive pcr this technique entails the coamplification of a target dna or cdna in a biological sample together with a known quantity of a targetspecific standard the competitor which is added exogenously to the sample and is almost MZ to the dna region to be amplified competitive pcr offers the advantage to render the pcr reaction independent of the number of amplification cycles since any intraassay R2 has the same effect on both target and competitor since the final ratio between target and competitor amplification products exactly reflects the initial ratio between the two species and being the amount of added competitor known cPCR allows the determination of the exact number of molecules of target with an accuracy that is still unsurpassed by any other alternative procedure including realtime pcr the protocols described in this chapter cover most of the possible applications of competitive pcr including the quantification of an mrna transcript and the simultaneous determination of multiple targets

contemporary relational theories in psychoanalysis recognize the fully twoperson nature of the clinical process both patient and therapist bring to the encounter their internal worlds in equal measure each exerting constant influence on the other to create a highly complex relational field from this perspective clinical vignettes should provide the same level of description of the therapists as of the patients contributions to the treatment process it is argued that the body of clinical relational literature in general has not kept up with its rich theoretical contributions this case vignette and discussion both in structure and content is an indepth illustration of the mutual construction of the clinical process clinical material is offered from an D2 phase of analytic treatment during which the therapeutic relationship and so the patients possibilities for growth and NC shifted from seeming stasis and impasse into new realms of experience of self and others the authors intent is to demonstrate with specificity the ways in which the experiential worlds of patient and therapist collide and influence each other to create the intersubjectins reduced the incidence of azoxymethane aominduced colon PT in rats to obtain insights into these effects global mRNA profiles of colons from rats with lifetime ingestion of casein cas control diet soy protein isolate spi and whey protein hydrolysate wph diets were determined

sirna is a powerful tool to control cellular processes at the posttranscriptional level however its therapeutic potential is limited because of low stability in biological fluids and the lack of simple and efficient delivery systems chemical modification of sirna could be used to increase its intracellular delivery but may affect its specific activity to overcome these obstacles we suggest a simple and ERP system capable of stabilization delivery and subsequent release of free AS sirna within cells with this in mind we reversibly modified the dsDNA gfpsirna with a phosphothioethanol pe portion via the reducible disulfide bond and incorporated the resulting sirnasspe conjugate in nanosized pegpe micelles in the mixed sirnasspepegpe micelles obtained sirna was wellprotected against degradation by nucleases for at least h and was released easily from these NPs in free form in the presence of glutathione gsh at a concentration mimicking the intracellular C2 in gfpc EC cells mixed gfpsirnasspepegpe micelles downregulate the gfp production fold more effectively than free sirna in addition sirnacontaining micelles showed none of the cytotoxic side effects typical for sirna delivery systems that are based on electrostatic association of sirna with cationic carriers thus a reversible sirnaphospholipid conjugate formulated into mixed micelles with pegpe can be an ERP nontoxic system for stabilization and delivery of sirna
