    The pathophysiology of Parkinson's disease is marked by the loss of dopaminergic neurons, which leads to striatal dopaminergic deficiency. This causes resting tremor, hypokinesia, rigidity, bradykinesia, and loss of postural reflexes. Most current treatments for Parkinson's disease aim to restore striatal dopamine signaling by increasing the supply of dopamine with oral levodopa (L-dopa), stimulating dopamine receptors directly using dopamine agonists, or inhibiting the reuptake of endogenous dopamine. L-dopa is standard therapy for patients with Parkinson's disease. However, with continued treatment and disease progression, the response to oral dopaminergic drugs becomes unstable and motor fluctuations emerge, including off periods and dyskinesia. Direct duodenal-administered infusible L-dopa/carbidopa is effective for the management of refractory motor fluctuations in some patient populations. However, enteral infusions cannot mimic the function of the normal dopaminergic brain, and around-the-clock constant-rate administration carries the risk of causing refractory off periods associated with severe immobility and hyperpyrexia. Subthalamic nucleus (STN) deep brain stimulation (DBS) is also a promising treatment. DBS passes a high-frequency electrical current into the target area, mimicking the effect of lesioning the stimulated area. However, this treatment requires invasive surgery and is appropriate for a limited segment of the patient population. This supplement provides a rationale for the use of continuous dopaminergic receptor stimulation and offers guidelines on the individualization of treatment decisions, with special focus on continuous L-dopa infusion and STN DBS. Erik Wolters, MD, PhD, offers an introduction to the impact of continuous L-dopa infusion. Andrew J. Lees, MD, FRCP, provides an overview of the physiologic response to L-dopa and reviews clinical pharmacologic studies of intravenous and intraduodenal L-dopa. Jens Volkmann, MD, discusses

    Continuing education is an ever-increasing need for medical technologists who want to maintain and upgrade their professional knowledge and skills. Professional groups strive to develop programs to meet a diversity of needs. Planning groups often encounter difficulty during the program development process as they identify topics and select effective educational strategies for presentation. In order to help identify topics of interest and desirable educational methods for the continuing education of laboratory personnel, a continuing medical technology education interest assessment tool was developed and used by a medical technology continuing education committee. Development and use of this assessment tool and resulting statistical survey results formed the basis for two continuing education courses, both considered highly successful.

  7. Continuous dopaminergic stimulation therapy for Parkinson's disease - recent advances.

    2016-08-01

    We aim to review the most interesting recent advances on the clinical aspects of continuous dopaminergic stimulation in Parkinson's disease. Several large, open-label studies have presented data that are in line with the randomized controlled trial on L-dopa-carbidopa intestinal gel infusion, which shows that a continuous drug delivery can improve motor fluctuations and dyskinesia in patients with advanced Parkinson's disease. Furthermore, new extended-release formulations of L-dopa aim to stabilize plasma concentrations and thus reduce the degree of motor complications - despite a reduced number of daily doses. Transdermal rotigotine has been shown to be effective for specific subgroups of patients, although the general effect on nonmotor symptoms is still unclear. New products for L-dopa infusion are also at different stages of development, but the routes of administration are widely different: intrajejunal, subcutaneous, and oral. The understanding of the mechanisms behind the complications of long-term L-dopa treatment is still not complete, but therapies aiming for continuous dopaminergic stimulation are already widely used in clinical practice and the evidence strength is improving. However, there is still an urgent need for both less invasive and less costly options in order to increase access to these therapies.

    We have developed an isolated continuous-waveform constant-current physiological stimulator that is powered and controlled by universal serial bus (USB) interface. The stimulator is composed of a custom printed circuit board (PCB), 16-MHz MSP430F2618 microcontroller with two integrated 12-bit digital to analog converters (DAC0, DAC1), high-speed H-Bridge, voltage-controlled current source (VCCS), isolated USB communication and power circuitry, two isolated transistor-transistor logic (TTL) inputs, and a serial 16 × 2 character liquid crystal display. The stimulators are designed to produce current stimuli in the range of ±15 mA indefinitely using a 20V source and to be used in ex vivo cardiac experiments, but they are suitable for use in a wide variety of research or student experiments that require precision control of continuous waveforms or synchronization with external events. The device was designed with customization in mind and has features that allow it to be integrated into current and future experimental setups. Dual TTL inputs allow replacement by two or more traditional stimulators in common experimental configurations. The MSP430 software is written in C++ and compiled with IAR Embedded Workbench 5.20.2.

    2008-12-01

    Continuous dopaminergic stimulation is the ideal approach for the management of Parkinson's disease (PD); this goal can be partially reached with dopamine agonists, but the need for a therapeutic strategy providing a strong and constant dopaminergic stimulation also in the advanced phase of the disease remains unmet. The application of levodopa/carbidopa-gel suspension directly in the duodenum (Duodopa) allows a continuous delivery by a portable pump, resulting in smoother levodopa plasmatic concentrations, and consequently in a physiologic continuous receptor stimulation. Clinical studies have demonstrated that duodenal infusion was associated with significantly better outcome compared to conventional treatment regarding global functioning, ability to walk, "off" time and motor fluctuations. A retrospective analysis of the long-term clinical experience with Duodopa evidenced that daily dose of levodopa decreased by 5% during follow-up. The profile of pharmacological adverse events of Duodopa was similar to that observed with oral administration; dislocation of the intestinal tube to the stomach was the most common technical problem.

  17. Deep brain stimulation and continuous dopaminergic stimulation in advanced Parkinson's disease.

    PubMed

    Wolters, Erik Ch

    2007-09-01

    Patients receiving oral levodopa, the standard treatment for Parkinson's disease (PD), eventually develop motor fluctuations and dyskinesias. Treatment options for patients with these symptoms include high-frequency deep brain stimulation of the subthalamic nucleus (STN-DBS) or continuous dopaminergic stimulation (CDS). STN-DBS is the prevalent surgical therapy for PD and has shown efficacy, but behavioural disorders, including cognitive problems, depression and suicidality have been reported. CDS can be achieved with oral dopamine agonists with a long half-life, transdermal or subcutaneous delivery of dopamine agonists, or intestinal levodopa infusion. Of these, duodenal levodopa infusion appears to be the most promising option in terms of both efficacy and safety.

  19. Combined transcranial alternating current stimulation and continuous theta burst stimulation: a novel approach for neuroplasticity induction.

    Non-invasive brain stimulation can induce functionally relevant plasticity in the human cortex, making it potentially useful as a therapeutic tool. However, the induced changes are highly variable between individuals, potentially limiting research and clinical utility. One factor that might contribute to this variability is the level of cortical inhibition at the time of stimulation. The alpha rhythm (~ 8-13 Hz) recorded with electroencephalography (EEG) is thought to reflect pulsatile cortical inhibition; therefore, targeting non-invasive brain stimulation to particular phases of the alpha rhythm may provide an approach to enhance plasticity induction. Transcranial alternating current stimulation (tACS) has been shown to entrain cortical oscillations in a frequency-specific manner. We investigated whether the neuroplastic response to continuous theta burst stimulation (cTBS) was enhanced by timing bursts of stimuli to the peak or the trough of a tACS-imposed alpha rhythm. While motor evoked potentials (MEPs) were unaffected when cTBS was applied in-phase with the peak of the tACS-imposed oscillation, MEP depression was enhanced when cTBS was applied in-phase with the trough. This enhanced MEP depression was dependent on the individual peak frequency of the endogenous alpha rhythm recorded with EEG prior to stimulation, and was strongest in those participants classified as non-responders to standard cTBS. These findings suggest that tACS may be used in combination with cTBS to enhance the plasticity response. Furthermore, the peak frequency of endogenous alpha, as measured with EEG, may be used as a simple marker to pre-select those individuals likely to benefit from this approach. © 2015 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

  20. Continuous theta-burst stimulation modulates tactile synchronization

    PubMed Central

    2013-01-01

    Background Temporal order judgement (TOJ) is the ability to detect the order of occurrence of two sequentially delivered stimuli. Previous research has shown that TOJ in the presence of synchronized periodic conditioning stimuli impairs TOJ performance, and this phenomenon is suggested to be mediated by GABAergic interneurons that cause perceptual binding across the two skin sites. Application of continuous theta-burst repetitive TMS (cTBS) over primary somatosensory cortex (SI) alters temporal and spatial tactile perception. The purpose of this study was to examine TOJ perception in the presence and absence of synchronized periodic conditioning stimuli before and after cTBS applied over left-hemisphere SI. A TOJ task was administered on the right index and middle finger (D2 and D3) in two separate sessions in the presence and absence of conditioning stimuli (a background low amplitude sinusoidal vibration). Results CTBS reduced the impact of the conditioning stimuli on TOJ performance for up to 18 minutes following stimulation while sham cTBS did not affect TOJ performance. In contrast, the TOJ task performed in the absence of synchronized conditioning stimulation was unaltered following cTBS. Conclusion We conclude that cTBS suppresses inhibitory networks in SI that mediate perceptual binding during TOJ synchronization. CTBS offers one method to suppress cortical excitability in the cortex and potentially benefit clinical populations with altered inhibitory cortical circuits. Additionally, TOJ measures with conditioning stimuli may provide an avenue to assess sensory processing in neurologically impaired patient populations. PMID:23968301

    Protection against diseases is mediated by a sustained immune response. Here, we describe a new immunization strategy. Mice implanted with encapsulated C2C12 myoblasts secreting human factor IX (hFIX) elicited a strong humoral response against the transgene, as compared to mice immunized with complete Freund's adjuvant (FA). Mice also had increasing IgG2a antibody titer, indicating a switch to a Th1 profile immune response. Mice developed strong hFIX-specific cytotoxic T lymphocytes (CTL) that was detectable 213 days after implantation, demonstrating the sustained immunity elicited by encapsulated cells. Here, we propose continuous antigenic stimulation system (CASS) as a novel immunization strategy with potential application in the design of novel vaccines.

    Stimulated Raman scattering (SRS) microscopy is a powerful tool for chemically sensitive non-invasive optical imaging. However, ultrafast laser sources, which are currently employed, are still expensive and require substantial maintenance to provide temporal overlap and spectral tuning. SRS imaging, which utilizes continuous-wave laser sources, has a major advantage, as it eliminates the cell damage due to exposure to the high-intensity light radiation, while substantially reducing the cost and complexity of the setup. As a proof-of-principle, we demonstrate microscopic imaging of dimethyl sulfoxide using two independent, commonly used lasers, a diode-pumped, intracavity doubled 532-nm laser and a He-Ne laser operating at 632.8-nm.

    2017-01-01

    Pump-based Parkinson (PD) therapies, including subcutaneous apomorphine infusion (CSA) and levodopa-carbidopa intestinal gel (LCIG), presently constitute the most effective pharmacological treatments available for advanced PD. These therapies are based on a more constant delivery of the dopaminergic drug resulting in a more continuous dopaminergic stimulation and a more stable treatment effect. This can be detected as reduction of time in off, reduction of dyskinesia frequency and severity, as well as increase of time in on without troublesome dyskinesias. A number of open-label studies now suggest that also the nonmotor PD symptomatology can improve under CSA and LCIG therapy. The most consistent improvements are seen concerning sleep, mood, and apathy, gastrointestinal symptoms, and urological symptoms. But also cardiovascular symptoms, perception, attention, and sexual function might show beneficial effects when moving from conventional therapies to pump treatment. Further there might be negative influences on some parts of the nonmotor symptomatology through side effects of CSA and LCIG therapy. In this chapter, we review the present knowledge about these aspects of the pump-based therapies. This information might be valuable when deciding on advanced therapy for individual patients. © 2017 Elsevier Inc. All rights reserved.

    Prefrontal cortex (PFC) plays an important role in the emotional processing as well as in the functional brain network. Hyperactivity in the right dorsolateral prefrontal cortex (DLPFC) would be found in anxious participants. However, it is still unclear what the role of PFC played in a resting functional network. Continuous theta burst transcranial magnetic stimulation (cTBS) is an effective tool to create virtual lesions on brain regions. In this paper, we applied cTBS over right prefrontal area, and investigated the effects of cTBS on the brain activity for functional connectivity by the method of graph theory. We recorded 64-channels EEG on thirteen healthy participants in the resting condition and emotional tasks before and after 40 s of cTBS. This work focused on the effect of cTBS on cortical activities in the resting condition by calculating the coherence between EEG channels and building functional networks before and after cTBS in the delta, theta, alpha and beta bands. Results revealed that 1) The functional connectivity after cTBS was significantly increased compared with that before cTBS in delta, theta, alpha and beta bands in the resting condition; 2) The efficiency-cost reached the maximum before and after cTBS both with the cost about 0.3 in the bands above, which meant that the information transmission of functional brain network with this cost was highly efficient; 3) the clustering coefficient and path length after cTBS was significantly increased in delta, theta and beta bands. In conclusion, cTBS over PFC indeed enhanced the functional connectivity in the resting condition. In addition, the information transmission in the resting brain network was highly efficient with the cost about 0.3.

    2010-03-01

    Individuals with spinal cord injury (SCI) exhibit neurogenic detrusor overactivity (NDO) causing high intravesicle pressures and incontinence. The first aim was to measure changes in maximum cystometric capacity (MCC) evoked by electrical stimulation of the dorsal genital nerve (DGN) delivered either continuously or conditionally (only during bladder contractions) in persons with SCI. The second aim was to use the external anal sphincter electromyogram (EMG(EAS)) for real-time control of conditional stimulation. Serial filling cystometries were performed in nine volunteers with complete or incomplete supra-sacral SCI. Conditional stimulation was delivered automatically when detrusor pressure increased to 8-12 cmH(2)O above baseline. MCCs were measured for each treatment (continuous, conditional, and no stimulation) and compared using post-ANOVA Tukey HSD paired comparisons. Additional treatments in two subjects used the EMG(EAS) for automatic control of conditional stimulation. Continuous and conditional stimulation increased MCC by 63 +/- 73 ml (36 +/- 24%) and 74 +/- 71 ml (51 +/- 37%), respectively (P < 0.05), compared to no stimulation. There was no significant difference between MCCs for conditional and continuous stimulation, but conditional stimulation significantly reduced stimulation time (174 +/- 154 sec, or 27 +/- 17% of total time) as compared to continuous stimulation (469 +/- 269 sec, 100% of total time, P < 0.001). The EMG(EAS) algorithm provided reliable detection of bladder contractions (six of six contractions over four trials) and reduced stimulation time (21 +/- 8% of total time). Conditional stimulation generates increases in bladder capacity while substantially reducing stimulation time. Furthermore, EMG(EAS) was successfully used as a real-time feedback signal to control conditional electrical stimulation in a laboratory setting. (c) 2009 Wiley-Liss, Inc.

    Altruism is a central underpinning of professional behavior; however physicians may face instances in which their secondary (financial) interest is in competition with their primary (patient health, research integrity, professional education) interests. Most medical institutions have developed policies to manage conflicts of interest, but chiropractic institutions, organizations and providers may not be well-acquainted with such policies. To compare the policies of the Department of Veterans Affairs (VA) and the North American Spine Society (NASS) regarding management of conflicts of interest in continuing medical education (CME). A qualitative review of published policies of the VA and NASS was performed. The policies of each organization were retrieved and reviewed, and data were entered into a spreadsheet for comparison. Content experts at each organization were contacted to provide additional information. The VA and NASS provide explicit, similar policies to manage conflicts of interest in CME. Proposed speakers are required to disclose the nature and value of financial relationships relevant to content of their planned talk/presentation. Procedures for committee review, mitigation of conflict, or prohibiting the participation of a given speaker have been described. Disclosure must be made to the attendees of an educational activity in printed materials and at the time of presentation. The VA and NASS appear similar in their policies to manage conflicts of interest in CME. The policies of the VA and NASS may provide examples for the chiropractic profession to consider in relation to chiropractic continuing education.

    The changes in the contractile properties induced by a 30-Hz phasic stimulation paradigm were measured and compared with the changes induced by a 10-Hz continuous stimulation paradigm. The study was performed on the tibialis anterior muscles of cats with one paradigm applied to one hindlimb muscle and the other to the contralateral limb. Both hindlimb muscles received the same number of stimuli in a day, making the average stimulation frequency 10 Hz. Two periods of daily stimulation were studied, 8 and 24 h/day. Muscles stimulated at 30 Hz produced greater overall tetanic tension and, during a prolonged stimulation test, exerted a greater mean tension than muscles stimulated at 10 Hz (50 and 32% increase for animals stimulated for 8 and 24 h/day, respectively). Muscle mass was least reduced and fewer pathological abnormalities were observed in the muscles stimulated at 30 Hz. There were no apparent differences in the histochemistry or biochemistry between muscles stimulated at 10 and 30 Hz, which could account for these differences in muscle properties. These results indicate the 30-Hz paradigm may be better suited than 10 Hz continuous stimulation for applications requiring sustained muscle tension such as correction of scoliosis or muscle conditioning for motor prostheses.

    Although the problem of conflict of interest in medical education is discussed intensively, few valid data have been published on how to deal with the form, content, funding, sponsorship, and the influence of economic interests in continuing medical education (CME). Against this background, we carried out an analysis of data which had been documented for the purpose of certification by a German Medical Association. A central aim of the study was to obtain evidence of possible influences of economic interests on continuing medical education. Furthermore, strategies for quality assurance of CME contents and their implementation were to be examined. We analyzed all registration data for courses certified in the category D ("structured interactive CME via print media, online media and audiovisual media") by the Bavarian Chamber of Physicians in 2012. To measure the effects of conflict of interest, relationships between topics of training and variables relating to the alleged self-interest of the organizer/sponsor (for example, drug sales in a group of physicians) were statistically verified. These data were taken from the Bavarian Medical Statistics 2012 and the GKV-Arzneimittelschnellinformation. In 2012, a total of 734 CME course offerings have been submitted for 51 medical specialties by 30 course suppliers in the Bavarian Medical Association. To ensure the neutrality of interests of the CME courses the course suppliers signed a cooperation treaty ensuring their compliance with defined behavior towards the Bavarian Medical Association concerning sponsorship. The correlation between course topics and drug data suggests that course suppliers tend to submit topics that are economically attractive to them. There was a significant correlation between the number of CME courses in a specific field and the sales from drug prescriptions issued by physicians in the respective field. The results show that neutrality of interests regarding continuing medical education is

    Subthreshold continuous theta burst stimulation of the visual cortex has been reported to cause inhibitory effects on phosphene threshold. In contrast, we observed no inhibition in a former study applying higher stimulation intensities. The main discrepancies between our experiments and the former studies were stimulation intensity and coil type. We aimed at investigating the role of these factors on the modulatory effects of continuous theta burst stimulation applied to the visual cortex. In a between-group-design, we used either a figure-of-eight-coil or a round coil, respectively. We measured phosphene thresholds prior and after continuous theta burst stimulation applied at 80% of individual phosphene threshold. With the figure-of-eight-coil, phosphene thresholds significantly decreased following stimulation. This is in line with the results of our former study but contrary to the increase observed in the other two studies. Using a round coil, no significant effect was observed. A correlation analysis revealed an inhibitory effect in subjects with higher phosphene thresholds only. Furthermore, the slope of the baseline phosphene threshold seems to predict the direction of modulation, independent from coil type. Thus, modulatory effects of continuous theta burst stimulation seem to depend on coil type and psychophysics parameters, probably due to different cortex volumes stimulated. Stochastic resonance phenomena might account for the differences observed. PMID:27459108

    The purpose of this study is to document and describe the policies governing conflict of interest (COI) among select organizations and institutions offering chiropractic continuing education. Surveys were sent to the following: all North American chiropractic colleges; major national chiropractic organizations; and state chiropractic organizations in states with more than 3500 licensed Doctors of Chiropractic. Each organization or institution was surveyed regarding written and verbal COI policies. Half of the respondents in this survey indicated that they had written policies for management of COI, whereas half did not. None included most of the common elements typically outlined in continuing medical education COI policies. Content varied among the policies available for review. Relevant financial interest is the issue most often defined, and respondents generally prohibit presenters from selling products or services directly during presentations. Overall, these results suggest that processes for managing COI in chiropractic CE are less robust than those previously described for continuing medical education. This study provides preliminary insight into the status of COI management in chiropractic CE.

    Optical nerve stimulation using infrared laser radiation has recently been developed as a potential alternative to electrical nerve stimulation. However, recent studies have focused primarily on pulsed delivery of the laser radiation and at relatively low pulse rates. The objective of this study is to demonstrate faster optical stimulation of the prostate cavernous nerves using continuous-wave (cw) infrared laser radiation for potential diagnostic applications. A thulium fiber laser (λ=1870 nm) is used for noncontact optical stimulation of the rat prostate cavernous nerves in vivo. Optical nerve stimulation, as measured by an intracavernous pressure (ICP) response in the penis, is achieved with the laser operating in either cw mode, or with a 5-ms pulse duration at 10, 20, 30, 40, 50, and 100 Hz. Successful optical stimulation is observed to be primarily dependent on a threshold nerve temperature (42 to 45 °C), rather than an incident fluence, as previously reported. cw optical nerve stimulation provides a significantly faster ICP response time using a lower power (and also less expensive) laser than pulsed stimulation. cw optical nerve stimulation may therefore represent an alternative mode of stimulation for intraoperative diagnostic applications where a rapid response is critical, such as identification of the cavernous nerves during prostate cancer surgery.

    For a number of reasons the general public and many young people are fascinated by the ideas of UFOs and extra-terrestrial life. As mysteries motivate to gain interest and knowledge, an opportunity exists, throughout these topics, to stimulate the people's interests to natural sciences and technology. A major problem however exists, concerning the fact that the general public generally associates any strange aerial sighting to something exotic, unknown, and to the possibility of extraterrestrial visitations. Rumours, irrational thinking and conspiracy theories prevail around these topics. Launched under the framework of the 2009 International Year of Astronomy, the Unidentified Aerospace Phenomena (UAP) Observations Reporting Scheme seeks to tackle this situation through approaching the topic from a professional and rational perspective, providing an opportunity to teach the public how to think more critically, demystifying UFO events, and ultimately attempting to stimulate the interest in natural sciences and technological disciplines. This is tentatively attempted through the following resources: Firstly, the project's website (1) provides an extensive resource for inquiry-based learning regarding the various natural or man-made phenomena that often give rise to false UAP sightings. It serves as a general forum for educating the public about human, atmospheric and astrophysical phenomena that could be observed in the sky. Secondly, the basic educational information provided on the web site allows potential UAP witnesses to critically evaluate the potential cause of their sightings. Visual descriptions, photos, video clips, tools, and links to relevant websites are provided for each category of phenomena, in order to assist the observer in his self-analysis. Amateur astronomers and societies who receive questions about UFOs can redirect queries to the website. Thirdly, the website provides novice observers viewing tips (e.g. elevation, azimuth, angular size) about

    Continuous nursing education (CNE) courses delivered through e-learning is believed to be an effective mode of learning for nurses. Implementation of e-learning modules requires pre-assessment of infrastructure and learners' characteristics. Understanding the learners' needs and their perspectives would facilitate effective e-learning delivery by addressing the underlying issues and providing necessary support to learners. The aim of this study was to examine access to computer and Internet facilities, interest in and preferences regarding e-learning, and attitudes toward e-learning among nurses in Peninsular Malaysia. The study utilized a cross-sectional descriptive survey. Government hospitals and community clinics in four main regions of Peninsular Malaysia. A total of 300 registered nurses. Data were collected using questionnaires, which consisted of demographic and background items and questions on access to computer and Internet facilities, interest and preferences in e-learning, and attitudes toward e-learning. Descriptive analysis and a chi-squared test were used to identify associations between variables. Most Malaysian nurses had access to a personal or home computer (85.3%, n=256) and computer access at work (85.3%, n=256). The majority had Internet access at home (84%, n=252) and at work (71.8%, n=215); however, average hours of weekly computer use were low. Most nurses (83%, n=249) did not have an e-learning experience but were interested in e-learning activities. Most nurses displayed positive attitudes toward e-learning. Average weekly computer use and interest in e-learning were positively associated with attitudes toward e-learning. Study findings suggest that organizational support is needed to promote accessibility of information and communications technology (ICT) facilities for Malaysian nurses to motivate their involvement in e-learning.

    Wallerian degeneration of the distal portion of a cut nerve is considered irreversible. A possible reason for degeneration is lack of axon stimulation in the distal, cut nerves. We hypothesized greater rates of stimulation of distal nerve stumps would prolong time to action potential propagation failure, and uncut nerves would not be damaged by implanted nerve stimulators. We also hypothesized that action potentials measured from the body of the sciatic nerve would show similar response as motor-evoked potentials measured in the muscles innervated by branches of the sciatic nerve. We implanted a nerve stimulator onto distal cut sciatic nerves of rats and recorded motor-evoked potentials. Three groups were stimulated at 1 Hz (once per second), 0.1 Hz (once per 10 seconds), and 0.01 Hz (once per 100 seconds) respectively. Motor-evoked potentials progressively declined after nerve transection, failing faster at 1 Hz (26.8 hours +/- 108 minutes) and 0.1 Hz (22 hours +/- 66 minutes) compared with stimulation at 0.01 Hz (36.75 hours +/- 83 minutes). Intact axons were not damaged by implanted nerve stimulators. Action potentials recorded directly from nerves were equivalent to motor- evoked potentials. Failure of motor-evoked potential transmission in a transected nerve is accelerated by a greater rate of continuous stimulation of the distal stump.

    We studied the relationship between exocytosis and endocytosis in rat pituitary somatotrophs using patch-clamp capacitance, FM1-43 fluorescence imaging and amperometry. Stimulation of exocytosis through voltage-dependent Ca2+ channels by depolarizations (1-5 s) increased the capacitance by 4.3 +/- 0.9 % and the fluorescence by 6.6 +/- 1.1 % (10 cells). The correlation between the capacitance and fluorescence changes indicated that the cell membrane and granule membrane added via exocytosis were stained with the membrane-bound fluorescent dye FM1-43 in a quantitatively similar manner. Intracellular dialysis (0.5-4.5 min) with elevated Ca2+ (1.5-100 microM) evoked continuous exocytosis that was detected with a carbon fibre electrode from dopamine-loaded cells (10 cells) or as an increase in FM1-43 fluorescence (56 +/- 10 %; 21 cells). Interestingly during Ca2+ dialysis the capacitance did not significantly change (2 +/- 1 %; 31 cells), indicating that endocytosis efficiently retrieved increased cell membrane. Sustained endocytosis was not blocked when the intracellular GTP (300 microM) was replaced with GTP[gamma]S. Replacing intracellular Ca2+ (100 microM) with Ba2+ (300 microM) or Sr2+ (200 microM), or reducing the pH of the intracellular solution from 7.2 to 6.2 did not block sustained endocytosis. Our results suggest that pituitary somatotrophs have the ability to undergo continuous exocytosis and membrane retrieval that persist in whole-cell recordings.

    Brain tumor surgery is at risk when lesions are located in eloquent areas. The interindividual anatomo-functional variability of the central nervous system implies that brain surgery within eloquent regions may induce neurological sequelae. Brain mapping using intraoperative direct electrical stimulation in awake patients has been for long validated as the standard for functional brain mapping. Direct electrical stimulation inducing a local transient electrical and functional disorganization is considered positive if the task performed by the patient is disturbed. The brain area stimulated is then considered as essential for the function tested. However, the exactitude of the information provided by this technique is cautious because the actual impact of cortical direct electrical stimulation is not known. Indeed, the possibility of false negative (insufficient intensity of the stimulation due to the heterogeneity of excitability threshold of different cortical areas) or false positive (current spread, interregional signal propagation responsible for remote effects, which make difficult the interpretation of positive or negative behavioural effects) constitute a limitation of this technique. To improve the sensitivity and specificity of this technique, we used an electrocorticographic recording system allowing a real time visualization of the local. We provide here evidence that direct cortical stimulation combined with electrocorticographic recording could be useful to detect remote after discharge and to adjust stimulation parameters. In addition this technique offers new perspective to better assess connectivity of cerebral networks.

    A first-person shooter video game was adapted for the study of choice between smaller sooner and larger later outcomes. Participants chose when to fire a weapon that increased in damage potential over a 10 s interval, an escalating interest situation. Across two experiments, participants demonstrated sensitivity to the nature of the mathematical function that defined the relationship between waiting and damage potential. In Experiment 1, people tended to wait longer when doing so allowed them to eliminate targets more quickly. In Experiment 2, people tended to wait longer to increase the probability of a constant magnitude outcome than to increase the magnitude of a 100% certain outcome that was matched for the same expected value (i.e., probability times magnitude). The two experiments demonstrated sensitivity to the way in which an outcome improves when the outcome is continuously available. The results also demonstrate that this new video game task is useful for generating sensitivity to delay to reinforcement over time scales that are typically used in nonhuman animal studies.

    Curiosity is fundamental to scientific inquiry and pursuance. Parents are important in encouraging children's involvement in science. This longitudinal study examined pathways from parental stimulation of children's curiosity per se to their science acquisition (SA). A latent variable of SA was indicated by the inter-related variables of high school science course accomplishments, career interest, and skill. A conceptual model investigated parental stimulation of children's curiosity as related to SA via science intrinsic motivation and science achievement. The Fullerton Longitudinal Study provided data spanning school entry through high school (N = 118). Parental stimulation of curiosity at age 8 years comprised exposing children to new experiences, promoting curiosity, encouraging asking questions, and taking children to a museum. Intrinsic motivation was measured at ages 9, 10, and 13 years, and achievement at ages 9, 10, and 11 years. Structural equation modelling was used for analyses. Controlling for socio-economic status, parental stimulation of curiosity bore positive and significant relations to science intrinsic motivation and achievement, which in turn related to SA. Gender neither related to stimulation of curiosity nor contributed to the model. Findings highlight the importance of parental stimulation of children's curiosity in facilitating trajectories into science, and relevance to science education is discussed.

    This study examined tolerance to cocaine's threshold-lowering effect in brain stimulation reward (BSR) following continuous cocaine infusions and secondly, used the nitric oxide synthase inhibitor Nω-nitro-L-arginine methyl ester (L-NAME) to determine NO's involvement in the development of cocaine tolerance. Animals were continuously infused with saline or cocaine (30 mg/kg per day) via osmotic minipump for 14 days and injected daily with saline or L-NAME (30 mg/kg, i.p.) following BSR testing. Saline-treated animals continuously infused with saline showed stable BSR thresholds across the 14-day infusion period. Saline-treated animals continuously infused with cocaine showed markedly lowered BSR thresholds on Day 1 followed by a progressive increase in BSR thresholds across the infusion period - indicating the development of tolerance. L-NAME-treated animals continuously infused with cocaine showed stimulation thresholds that were not significantly different from saline-treated animals continuously infused with cocaine. A cocaine challenge injection (10 mg/kg, i.p.) administered 3 and again at 10 days following minipump removal revealed that saline-treated animals continuously infused with saline showed lowered BSR thresholds. Saline-treated animals continuously infused with cocaine displayed lowered BSR thresholds that were not significantly different from saline-infused animals. L-NAME treated animals continuously infused with cocaine showed higher BSR thresholds to a challenge 3 days following pump removal. However, stimulation thresholds for this group failed to reach statistical significance on both days (i.e., Days 3 and 10) following pump removal. Results showed that animals continuously infused with cocaine develop robust tolerance to cocaine's threshold-lowering effect during the 14-day infusion period. Tolerance to cocaine's threshold-lowering effect was short-lived and dissipated soon after minipump removal. L-NAME treatment failed to significantly

    The use of cerebellar repetitive transcranial magnetic stimulation has been attempted for perturbing reflexive and voluntary eye movements, but discrepancies are seen between the results of distinct studies possibly due to the different stimulation sites, intensities, and paradigms. We describe the after effects of 20 and 40 s continuous Theta Burst Stimulation (cTBS) as compared to sham stimulation, applied over the lateral cerebellar vermis and paravermis on Reflexive Saccades (RS) and Smooth Pursuit (SP) eye movements, recorded in the 30 min following stimulation. The experiments were carried out in eight healthy volunteers, and eye movements were recorded monocularly with video-oculography. The 40 s cTBS significantly increased the amplitude of ipsilateral RS and the acceleration of the ipsilateral SP, and this effect was detectable all over the 30-min recording period; 40 s cTBS did not modify the other parameters, namely the peak velocity, the duration and the latency of RS, and the latency and the velocity of SP. The 20 s cTBS was ineffective on all RS and SP parameters. Finally, we detected a significant quite-linear reduction of RS peak velocity over time, but this was independent from cTBS and was probably caused by fatigue. The effects of 40 s cTBS in our experiments mimic the disorder of ocular motility in Wallenberg's syndrome and could result from functional impairment of cerebellopontine pathways. This effect lasts 30 min at least, and can provide a useful framework for adaptive ocular motor studies.

    1999-01-01

    To plan targeted, relevant continuing medical educational activities, a study was undertaken to assess demographic data, practice patterns, and current continuing medical educational needs of former graduates of the physical medicine and rehabilitation program. A survey was sent to the 168 physicians who had completed a physical medicine and rehabilitation residency program from 1961 to 1995 and to the 34 then current residents in the program. Questions were asked regarding gender, year of completion of residency, certification, fellowships, current employment situation, size of practice community, work time distribution, and busiest areas of clinical practice. In addition, from a list of 47 topics plus "other," the respondents indicated in which topics they had a current strong interest in continuing their education. They also responded to questions about their most important considerations when deliberating about attending an educational activity, the amount of notice required regarding an upcoming course, and the preferred duration of educational activities. The response rate of former residents was 56% and of then current residents was 100%. Topics of interest to greater than half of the respondents, in descending order, were musculoskeletal/soft tissue disorders, therapeutic injections/nerve blocks, industrial medicine, back and neck pain rehabilitation, and sports-related disorders. There were significant differences on some topics based on gender, year of residency completion, academic affiliation, private practice, and ratings of residency training in that topic. The most important consideration when deciding whether to attend an educational activity was, by far, interest in topic, followed by provision of continuing medical educational credits. There are among physiatrists several differences in educational interests that challenge continuing medical education planners to determine efficient, effective ways to deliver continuing medical education to meet

  19. Managing perceived conflicts of interest while ensuring the continued innovation of medical technology.

    2011-09-01

    If it were not for the ongoing collaboration between vascular surgeons and the medical technology industry, many of these advanced treatments used every day in vascular interventional surgery would not exist. The flip side of this coin is that these vital relationships create multiple roles for surgeons and must be appropriately managed. The dynamic process of innovation, along with factors such as product delivery technique refinement, education, testing and clinical trials, and product support, all make it necessary for ongoing and close collaboration between surgeons and the device industry. This unique relationship sometimes leads to the perception of conflicts of interest for physicians, in part because the competing pressures from the multiple, overlapping roles as clinician/caregiver/investigator/innovator/customer are significant. To address this issue, the Advanced Medical Technology Association (AdvaMed), the nation's largest medical technology association representing medical device and diagnostics companies, developed a Code of Ethics to guide medical technology companies in their interactions with health care professionals. First introduced in 1993, the AdvaMed Code strongly encourages both industry and physicians to commit to openness and high ethical standards in the conduct of their business interactions. The AdvaMed Code addresses many of the types of interactions that can occur between companies and health care professionals, including training, consulting agreements, the provision of demonstration and evaluation units, and charitable donations. By following the Code, companies send a strong message that treatment decisions must always be based on the best interest of the patient.

    2012-05-01

    We investigated whether essential tremor (ET) can be altered by suppressing the corticospinal excitability in the primary motor cortex (M1) with transcranial magnetic stimulation. 10 Patients with ET and 10 healthy controls underwent transcranial continuous theta-burst stimulation (cTBS) of the left primary motor hand area at 80% (real cTBS) and 30% (control cTBS) of active motor threshold in two separate sessions at least one week apart. Postural tremor was rated clinically and measured accelerometrically before and after cTBS. Corticospinal excitability was assessed by recording the motor evoked potentials (MEP) from the first dorsal interosseous muscle. Real cTBS but not control cTBS reduced the tremor total power assessed with accelerometry. This beneficial effect was subclinical as there were no significant changes in clinical tremor rating after real cTBS. Relative to control cTBS, real cTBS reduced corticospinal excitability in the stimulated primary motor cortex only in healthy controls but not in ET patients. Real cTBS has a beneficial effect on ET. Since cTBS did not induce a parallel reduction in corticospinal excitability, this effect was not mediated by a suppression of the corticospinal motor output. "Inhibitory" cTBS of M1 leads to a consistent but subclinical reduction in tremor amplitude. Copyright © 2011 International Federation of Clinical Neurophysiology. Published by Elsevier Ireland Ltd.

  1. Electrical stimulation vs. pulsed and continuous-wave optical stimulation of the rat prostate cavernous nerves, in vivo

    2015-07-01

    Identification and preservation of the cavernous nerves (CNs) during prostate cancer surgery is critical for post-operative sexual function. Electrical nerve stimulation (ENS) mapping has previously been tested as an intraoperative tool for CN identification, but was found to be unreliable. ENS is limited by the need for electrode-tissue contact, poor spatial precision from electrical current spreading, and stimulation artifacts interfering with detection. Alternatively, optical nerve stimulation (ONS) provides noncontact stimulation, improved spatial selectivity, and elimination of stimulation artifacts. This study compares ENS to pulsed/CW ONS to explore the ONS mechanism. A total of eighty stimulations were performed in 5 rats, in vivo. ENS (4 V, 5 ms, 10 Hz) was compared to ONS using a pulsed diode laser nerve stimulator (1873 nm, 5 ms, 10 Hz) or CW diode laser nerve stimulator (1455 nm). Intracavernous pressure (ICP) response and nerve compound action potentials (nCAPs) were measured. All three stimulation modes (ENS, ONS-CW, ONS-P) produced comparable ICP magnitudes. However, ENS demonstrated more rapid ICP response times and well defined nCAPs compared to unmeasurable nCAPs for ONS. Further experiments measuring single action potentials during ENS and ONS are warranted to further understand differences in the ENS and ONS mechanisms.

    Time perception in the millisecond and second ranges is thought to be processed by different neural mechanisms. However, whether there is a sharp boundary between these ranges and whether they are implemented in the same, overlapped or separate brain areas is still not certain. To probe the role of the right dorsolateral prefrontal cortex (dlPFC), the right supplementary motor area (SMA), and the cerebellum on time perception, we temporarily altered their activity on healthy volunteers on separate sessions using transcranial magnetic stimulation with the continuous Theta Burst Stimulation (cTBS) protocol. A control session was reserved for the stimulation of the primary somatosensory cortex (S1). Before and after stimulation, participants were tested on a temporal categorization task using intervals in the hundreds and thousands of milliseconds ranges, as well as on a pitch categorization task which was used as a further control. We then looked for changes in the Relative Threshold and the Constant Error, which, respectively, reflect participants' sensitivity to interval duration and their accuracy at setting an interval that acts as a boundary between categories. We found that after cTBS in all of the studied regions, the Relative Threshold, but not the Constant Error, was affected and only when hundreds of milliseconds intervals were being categorized. Categorization of thousands of milliseconds intervals and of pitch was not affected. These results suggest that the fronto-cerebellar circuit is particularly involved in the estimation of intervals in the hundreds of milliseconds range. Copyright © 2017 IBRO.

    Extension plant pathologists deliver science-based information that protects the economic value of agricultural and horticultural crops in the United States by educating growers and the general public about plant diseases. Extension plant pathologists diagnose plant diseases and disorders, provide advice, and conduct applied research on local and regional plant disease problems. During the last century, extension plant pathology programs have adjusted to demographic shifts in the U.S. population and to changes in program funding. Extension programs are now more collaborative and more specialized in response to a highly educated clientele. Changes in federal and state budgets and policies have also reduced funding and shifted the source of funding of extension plant pathologists from formula funds towards specialized competitive grants. These competitive grants often favor national over local and regional plant disease issues and typically require a long lead time to secure funding. These changes coupled with a reduction in personnel pose a threat to extension plant pathology programs. Increasing demand for high-quality, unbiased information and the continued reduction in local, state, and federal funds is unsustainable and, if not abated, will lead to a delay in response to emerging diseases, reduce crop yields, increase economic losses, and place U.S. agriculture at a global competitive disadvantage. In this letter, we outline four recommendations to strengthen the role and resources of extension plant pathologists as they guide our nation's food, feed, fuel, fiber, and ornamental producers into an era of increasing technological complexity and global competitiveness.

    A case-based approach was used in a two-day periodontal continuing professional development course as a strategy to stimulate active learning. The present study investigates the outcome of this course format in terms of feasibility, perceived efficiency as a learning approach and reported individual learning goals. The study was performed in five identical courses entitled'risk analysis and treatment in periodontal patients'at Malmö University between 2011-2014. Before the course, clinical cases were used to activate participants' prior knowledge and to attune their focus on the course content. During the course, cases were discussed to synchronise theory with practical application. A pre- and end-course questionnaire were developed to evaluate participants' characteristics (age, clinical expertise, experience and expectations), perceptions on feasibility and instructiveness and emerged individual learning goals. The participants (39 dentists and 78 dental hygienists) reported an average preparation time of 62 minutes (range 2-190) and had positive perceptions on the accessibility, instructiveness and difficulty of cases. Expectations ranged between refreshing, acquiring new knowledge and mastering the course subject. Most reported learning goals were related to daily clinical practice including the development of a treatment plan, when to continue non-surgical treatment or to extract teeth/perform surgery, the approach to periodontitis, how to motivate non-compliant patients and when to refer. Conclusion: The use of clinical cases to stimulate active learning in a short-term continuing professional development periodontal course was positively perceived by the dentists and dental hygienists in terms of feasibility and learning potential.

    We previously have shown that manual stimulation (MS) of vibrissal muscles for 2 months after facial nerve injury in rats improves whisking and reduces motor end plate polyinnervation. Here, we seek to determine whether discontinuing or delaying MS after facial-facial anastomosis (FFA) leads to similar results. Rats were subjected to FFA and received MS for (1) 4 months (early and continued), (2) the first but not the last 2 months (discontinued), or (3) the last 2 months (delayed). Intact animals and those not receiving MS (no MS) were also examined. Early and continued MS restored whisking amplitude to 43°, a value significantly higher compared with the discontinued, delayed, and no MS groups (32°, 24°, and 10°, respectively). Motor end plate polyinnervation occurred in all experimental groups but was significantly higher in the delayed group. Early and continued MS results in better recovery than when it is either discontinued or delayed. Muscle Nerve, 2017. © 2017 Wiley Periodicals, Inc.

    'Temporally urgent' reactions are extremely rapid, spatially precise movements that are evoked following discrete stimuli. The involvement of primary motor cortex (M1) and its relationship to stimulus intensity in such reactions is not well understood. Continuous theta burst stimulation (cTBS) suppresses focal regions of the cortex and can assess the involvement of motor cortex in speed of processing. The primary objective of this study was to explore the involvement of M1 in speed of processing with respect to stimulus intensity. Thirteen healthy young adults participated in this experiment. Behavioral testing consisted of a simple button press using the index finger following median nerve stimulation of the opposite limb, at either high or low stimulus intensity. Reaction time was measured by the onset of electromyographic activity from the first dorsal interosseous (FDI) muscle of each limb. Participants completed a 30 min bout of behavioral testing prior to, and 15 min following, the delivery of cTBS to the motor cortical representation of the right FDI. The effect of cTBS on motor cortex was measured by recording the average of 30 motor evoked potentials (MEPs) just prior to, and 5 min following, cTBS. Paired t-tests revealed that, of thirteen participants, five demonstrated a significant attenuation, three demonstrated a significant facilitation and five demonstrated no significant change in MEP amplitude following cTBS. Of the group that demonstrated attenuated MEPs, there was a biologically significant interaction between stimulus intensity and effect of cTBS on reaction time and amplitude of muscle activation. This study demonstrates the variability of potential outcomes associated with the use of cTBS and further study on the mechanisms that underscore the methodology is required. Importantly, changes in motor cortical excitability may be an important determinant of speed of processing following high intensity stimulation.

    In this study we investigated in healthy subjects whether continuous theta-burst stimulation (cTBS) over the lateral cerebellum alters motor practice and retention phases during ipsilateral index finger and arm reaching movements. In 12 healthy subjects we delivered cTBS before repeated index finger abductions or arm reaching movements differing in complexity (reaching-to-grasp and reaching-to-point). We evaluated kinematic variables for index finger and arm reaching movements and changes in primary motor cortex (M1) activity tested with transcranial magnetic stimulation. Peak acceleration increased during motor practice for index finger abductions and reaching-to-grasp movements and persisted during motor retention. Peak acceleration decreased during motor practice for reaching-to-point movements and the decrease remained during motor retention. Cerebellar cTBS left the changes in peak acceleration during motor practice for index finger abductions and reaching-to-grasp arm movements unchanged but reduced peak acceleration at motor retention. Cerebellar cTBS prevented the decrease in peak acceleration for reaching-to-point movements during motor practice and at motor retention. Index finger abductions and arm reaching movements increased M1 excitability. Cerebellar cTBS decreased the motor evoked potential (MEP) facilitation induced by index finger movements, but increased the MEP facilitation after reaching-to-grasp and reaching-to-point movements. Cerebellar stimulation prevents motor retention for index finger abductions, reaching-to-grasp and reaching-to-point movements and degrades motor practice only for reaching-to-point movements. Cerebellar cTBS alters practice-related changes in M1 excitability depending on how intensely the cerebellum contributes to the task. Changes in M1 excitability reflect mechanisms of homeostatic plasticity elicited by the interaction of an 'exogenous' (cTBS-induced) and an 'endogenous' (motor practice-induced) plasticity

    Continuous wave (CW) stimulated Brillouin scattering (SBS) phase conjugation in step-index optical fibers was studied experimentally and modeled as a function of fiber length. A phase conjugate fidelity over 80% was measured from SBS in a 40 m fiber using a pinhole technique. Fidelity decreases with fiber length, and a fiber with a numerical aperture (NA) of 0.06 was found to generate good phase conjugation fidelity over longer lengths than a fiber with 0.13 NA. Modeling and experiment support previous work showing the maximum interaction length which yields a high fidelity phase conjugate beam is inversely proportional to the fiber NA(2), but find that fidelity remains high over much longer fiber lengths than previous models calculated. Conditions for SBS beam cleanup in step-index fibers are discussed.

    Models that simulate clinical conditions are needed to gain an understanding of the mechanism involved during spinal cord stimulation (SCS) treatment of chronic neuropathic pain. An animal model has been developed for continuous SCS in which animals that have been injured to develop neuropathic pain behavior were allowed to carry on with regular daily activities while being stimulated for 72 hours. Sprague-Dawley rats were randomized into each of six different groups (N = 10-13). Three groups included animals in which the spared nerve injury (SNI) was induced. Animals in two of these groups were implanted with a four-contact electrode in the epidural space. Animals in one of these groups received stimulation for 72 hours continuously. Three corresponding sham groups (no SNI) were included. Mechanical and cold-thermal allodynia were evaluated using von Frey filaments and acetone drops, respectively. Mean withdrawal thresholds were compared. Statistical significance was established using one-way ANOVAs followed by Holm-Sidak post hoc analysis. Continuous SCS attenuates mechanical allodynia in animals with neuropathic pain behavior. Mechanical withdrawal threshold increases significantly in SNI animals after 24 and 72 hours stimulation vs. SNI no stimulation (p = 0.007 and p < 0.001, respectively). SCS for 24 and 72 hours provides significant increase in mechanical withdrawal thresholds relative to values before stimulation (p = 0.001 and p < 0.001, respectively). Stimulation did not provide recovery to baseline values. SCS did not seem to attenuate cold-thermal allodynia. A continuous SCS model has been developed. Animals with neuropathic pain behavior that were continuously stimulated showed significant increase in withdrawal thresholds proportional to stimulation time. © 2015 International Neuromodulation Society.

  10. Continuous Wave Stimulated Raman Spectroscopy Inside a Hollow Core Photonic Crystal Fiber

    2013-06-01

    Hollow-core photonic crystal fibers (HCPCF) have raised new opportunities to study light-matter interaction. Dielectric or metallic capillaries are intrinsically lossy, making poor light guides. In contrast, HCPCFs can guide light quite efficiently, due to the band-gap effect produced by an array of smaller channels which surrounds a central hollow core with a few μm diameter. The tight confinement of light inside the core, that can be filled with gases, as well as a long interaction length, enhance multiple nonlinear phenomena, making it possible to devise new ways to do low signal level spectroscopy, as is the case of high resolution stimulated Raman spectroscopy (SRS). A. Owyoung demonstrated high resolution continuous wave SRS in 1978. Shortly afterwards, seeking higher sensitivity, he developed the quasi-continuous SRS technique (a high peak power pump laser, interacting with a low power cw probe laser). That variant remains today the best compromise between resolution and sensitivity for gas-phase Raman spectroscopy. In this work, we show the possibility of fully cw stimulated Raman spectroscopy, using a gas cell built around a HCPCF to overcome the limitations posed by the weakness of the stimulated Raman effect when not using pulsed sources. The interaction length (1.2 m), longer than that of a multiple pass refocusing cell, and the narrow diameter of the core (4.8 μm), can compensate for the much lower laser powers used in the cw set-up. The experimental complexity is considerably reduced and the instrumental resolution is at the 10's of MHz level, limited, with our fiber, by transit time effects. At present, we have demonstrated the feasibility of the experiment, a sensitivity enhancement of ˜ 6000 over the single focus regime, and a spectral resolution better than 0.005 wn in the unresolved Q-branch of the ν_1 component of the Fermi dyad of CO_2 at 1388 wn. Other examples of rotationally resolved spectra will be shown: the Q branch of O_2 at 1555 wn

    Stimulated emission depletion (STED) microscopy provides a new opportunity to study fine sub-cellular structures and highly dynamic cellular processes, which are challenging to observe using conventional optical microscopy. Using actin as an example, we explored the feasibility of using a continuous wave (CW)-STED microscope to study the fine structure and dynamics in fixed and live cells. Actin plays an important role in cellular processes, whose functioning involves dynamic formation and reorganization of fine structures of actin filaments. Frequently used confocal fluorescence and STED microscopy dyes were employed to image fixed PC-12 cells (dyed with phalloidin- fluorescein isothiocyante) and live rat chondrosarcoma cells (RCS) transfected with actin-green fluorescent protein (GFP). Compared to conventional confocal fluorescence microscopy, CW-STED microscopy shows improved spatial resolution in both fixed and live cells. We were able to monitor cell morphology changes continuously; however, the number of repetitive analyses were limited primarily by the dyes used in these experiments and could be improved with the use of dyes less susceptible to photobleaching. In conclusion, CW-STED may disclose new information for biological systems with a proper characteristic length scale. The challenges of using CW-STED microscopy to study cell structures are discussed. PMID:26393614

    The present study investigated the effects of continuous theta-burst stimulation (cTBS) over primary somatosensory (SI) and motor (M1) cortices on motor-evoked potentials (MEPs) and short-latency afferent inhibition (SAI). MEPs and SAI were recorded from the first dorsal interosseous (FDI) muscle of the right hand following 30Hz cTBS over left-hemisphere SI and M1 delivered to the same participants in separate sessions. Measurements were taken before and up to 60min following cTBS. CTBS over M1 suppressed MEPs and did not alter SAI. In contrast cTBS over SI facilitated MEPs and decreased median and digital nerve evoked SAI. These findings indicate that SAI amplitude is influenced by cTBS over SI but not M1, suggesting an important role for SI in the modulation of this circuit. These data provide further evidence that cTBS over SI versus M1 has opposite effects on corticospinal excitability. To date, plasticity-inducing TMS protocols delivered over M1 have failed to modulate SAI, and the present research continues to support these findings. However, in young adults, cTBS over SI acts to reduce SAI and simultaneously increase corticospinal excitability. Future studies may investigate the potential to modulate SAI via targeting neural activity within SI. Copyright © 2014 International Federation of Clinical Neurophysiology.

  13. Symbol recognition produced by points of tactile stimulation: the illusion of linear continuity.

    PubMed

    To determine whether tactile receptive communication is possible through the use of a mechanical device that produces the phi phenomenon on the body surface. Twenty-six subjects (11 blind and 15 sighted participants) were tested with use of a tactile communication device (TCD) that produces an illusion of linear continuity forming numbers on the dorsal aspect of the wrist. Recognition of a number or number set was the goal. A TCD with protruding and vibrating solenoids produced sequentially delivered points of cutaneous stimulation along a pattern resembling numbers and created the illusion of dragging a vibrating stylet to form numbers, similar to what might be felt by testing for graphesthesia. Blind subjects recognized numbers with fewer trials than did sighted subjects, although all subjects were able to recognize all the numbers produced by the TCD. Subjects who had been blind since birth and had no prior tactile exposure to numbers were able to draw the numbers after experiencing them delivered by the TCD even though they did not recognize their meaning. The phi phenomenon is probably responsible for the illusion of continuous lines in the shape of numbers as produced by the TCD. This tactile illusion could potentially be used for more complex tactile communications such as letters and words.

    Background: Modulation of cortical excitability by transcranial magnetic stimulation (TMS) is used for investigating human brain functions. A common observation is the high variability of long-term depression (LTD)-like changes in human (motor) cortex excitability. This study aimed at analyzing the response subgroup distribution after paired continuous theta burst stimulation (cTBS) as a basis for subject selection. Methods: The effects of paired cTBS using 80% active motor threshold (AMT) in 31 healthy volunteers were assessed at the primary motor cortex (M1) corresponding to the representation of the first dorsal interosseous (FDI) muscle of the left hand, before and up to 50 min after plasticity induction. The changes in motor evoked potentials (MEPs) were analyzed using machine-learning derived methods implemented as Gaussian mixture modeling (GMM) and computed ABC analysis. Results: The probability density distribution of the MEP changes from baseline was tri-modal, showing a clear separation at 80.9%. Subjects displaying at least this degree of LTD-like changes were n = 6 responders. By contrast, n = 7 subjects displayed a paradox response with increase in MEP. Reassessment using ABC analysis as alternative approach led to the same n = 6 subjects as a distinct category. Conclusion: Depressive effects of paired cTBS using 80% AMT endure at least 50 min, however, only in a small subgroup of healthy subjects. Hence, plasticity induction by paired cTBS might not reflect a general mechanism in human motor cortex excitability. A mathematically supported criterion is proposed to select responders for enrolment in assessments of human brain functional networks using virtual brain lesions. PMID:28824394

    2016-03-01

    Quantitative probing of the mechanical properties of scattering media by Brillouin spectroscopy is an emerging field of research. At present, Brillouin spectrometers typically detect spontaneous Brillouin backscattered signals from the sample using setups that comprise virtually imaged phased arrays (VIPAs) cascaded in cross-axis configuration or heated molecular absorption cells prior to the VIPA. These experimental arrangements are necessary in order to significantly suppress the strong elastic scattering background from the medium. In this talk, we present a different approach for Brillouin spectroscopy of scattering matter based on stimulated Brillouin scattering (SBS) amplification. Unlike spontaneous Brillouin scattering, SBS amplification does not show elastic scattering background due to the resonant nature of the amplification process, thereby providing excellent spectral contrast. We demonstrate that the use of two continuous-wave distributed feedback lasers at 780 nm in a counter-propagating SBS amplifier geometry is useful for acquiring high signal-to-noise ratio SBS spectra of Intralipid solutions at concentrations that yield up to ~3 scattering events for photons propagating through the sample. Potential applications of SBS spectroscopy in mechanical characterization of thin tissue sections and biopolymers will be discussed.

    Although it is well established that regions of premotor cortex (PMC) are active during action observation, it remains controversial whether they play a causal role in action understanding. In the experiment reported here, we used off-line continuous theta-burst stimulation (cTBS) to investigate this question. Participants received cTBS over the hand and lip areas of left PMC, in separate sessions, before completing a pantomime-recognition task in which half of the trials contained pantomimed hand actions, and half contained pantomimed mouth actions. The results reveal a double dissociation: Participants were less accurate in recognizing pantomimed hand actions after receiving cTBS over the hand area than over the lip area and less accurate in recognizing pantomimed mouth actions after receiving cTBS over the lip area than over the hand area. This finding constrains theories of action understanding by showing that somatotopically organized regions of PMC contribute causally to action understanding and, thus, that the mechanisms underpinning action understanding and action performance overlap.

    Traditional theories of backward priming account only for the priming effects found at long stimulus onset asynchronies (SOAs). Here, we suggest that the presence of backward priming at short SOAs may be related to the integrative role of the cerebellum. Previous research has shown that the right cerebellum is involved in forward associative priming. Functional magnetic resonance imaging reveals some activation of the left cerebellar hemisphere during backward priming; but what this activation represents is unclear. Here we explore this issue using continuous theta-burst transcranial magnetic stimulation (cTBS) and associative priming in a lexical decision task. We tested the hypothesis that the left cerebellum plays a role in backward priming and that this is dissociated from the role of the right cerebellum in forward priming. Before and after cTBS was applied to their left and right cerebellar hemispheres, participants completed a lexical decision task. Although we did not replicate the forward priming effect reported in the literature, we did find a significant increase in backward priming after left relative to right cerebellar cTBS. We consider how theories of cerebellar function in the motor domain can be extended to language and cognitive models of backward priming.

    Optical nerve stimulation has recently been developed as an alternative to electrical nerve stimulation. However, recent studies have focused primarily on pulsed delivery of the laser radiation and at relatively low pulse rates. The objective of this study is to demonstrate faster optical stimulation of the prostate cavernous nerves using continuouswave (CW) infrared laser radiation, for potential diagnostic applications. A Thulium fiber laser (λ = 1870 nm) was used for non-contact optical stimulation of the rat prostate cavernous nerves, in vivo. Optical nerve stimulation, as measured by an intracavernous pressure (ICP) response in the penis, was achieved with the laser operating in either CW mode, or with a 5-ms pulse duration at 10, 20, 30, 40, 50, and 100 Hz. Successful optical stimulation was observed to be primarily dependent on a threshold nerve temperature (42-45 °C), not an incident fluence, as previously reported. CW optical nerve stimulation provides a significantly faster ICP response time using a laser with lower power output than pulsed stimulation. CW optical nerve stimulation may therefore represent an alternative mode of stimulation for intra-operative diagnostic applications where a rapid response is critical, such as identification of the cavernous nerves during prostate cancer surgery.

    Intraoperative neuromonitoring (IONM) facilitates recurrent laryngeal nerve (RLN) identification, but various studies affirm virtually unchanged postoperative RLN palsy rates. Several authors meanwhile suggest continuous intraoperative neuromonitoring (CIONM) via vagal nerve stimulation (VNS) to improve RLN protection. However, knowledge of side effects of electrical VNS derives mainly from its therapeutic applications in the fields of neurology and psychiatry. The presented study was conducted to further evaluate the safety of CIONM and identify possible VNS related side effects. Prospective nonrandomized controlled trail. Forty patients scheduled for thyroid or parathyroid surgery were enrolled in the trail. The intervention group consisted of 22 patients receiving VNS for CIONM. Eighteen patients were operated on with routine IONM. To assess VNS-induced effects on the autonomic nervous system (ANS), heart rate variability analysis (HRVA) was applied. Serum cytokine levels of tumor necrosis factor (TNF)-α were monitored to evaluate immunomodulatory effects of VNS. HRVA revealed significantly increased vagal activity during CIONM. This parasympathetic predominance was not countered by the sympathetic nervous system. Despite a significant increase of vagal tone, no hemodynamic events occurred; in fact, no significant changes in median heart rate or in median arterial blood pressure were detected. Even though anti-inflammatory effects of VNS have been reported, no attenuation of cytokine release of TNF-α was measured. VNS for CIONM resulted in increased vagal activity assessable via HRVA. The increased parasympathetic tone affected neither hemodynamics nor levels of the proinflammatory cytokine TNF-α. VNS for CIONM appears safe with the applied settings.

    The dorsolateral prefrontal cortex (DLPFC) plays a key role in working memory. Evidence indicates that transcranial magnetic stimulation (TMS) over the DLPFC can interfere with working memory performance. Here we investigated for how long continuous theta-burst stimulation (cTBS) over the DLPFC decreases working memory performance and whether the effect of cTBS on performance depends on working memory load. Forty healthy young subjects received either cTBS over the left DLPFC or sham stimulation before performing a 2-, and 3-back working memory letter task. An additional 0-back condition served as a non-memory-related control, measuring general attention. cTBS over the left DLPFC significantly impaired 2-back working memory performance for about 15 min, whereas 3-back and 0-back performances were not significantly affected. Our results indicate that the effect of left DLPFC cTBS on working memory performance lasts for roughly 15 min and depends on working memory load.

    The prefrontal cortex is known to play a key role in higher-order cognitive functions. Recently, we showed that this brain region is active in reinforcement learning, during which subjects constantly have to integrate trial outcomes in order to optimize performance. To further elucidate the role of the dorsolateral prefrontal cortex (DLPFC) in reinforcement learning, we applied continuous theta-burst stimulation (cTBS) either to the left or right DLPFC, or to the vertex as a control region, respectively, prior to the performance of a probabilistic learning task in an fMRI environment. While there was no influence of cTBS on learning performance per se, we observed a stimulation-dependent modulation of reward vs. punishment sensitivity: Left-hemispherical DLPFC stimulation led to a more reward-guided performance, while right-hemispherical cTBS induced a more avoidance-guided behavior. FMRI results showed enhanced prediction error coding in the ventral striatum in subjects stimulated over the left as compared to the right DLPFC. Both behavioral and imaging results are in line with recent findings that left, but not right-hemispherical stimulation can trigger a release of dopamine in the ventral striatum, which has been suggested to increase the relative impact of rewards rather than punishment on behavior.

    The aim of this animal study was to investigate the effect of intraoperative pelvic nerve stimulation on internal anal sphincter electromyographic signals in order to evaluate its possible use for neuromonitoring during nerve-sparing pelvic surgery. Eight pigs underwent low anterior rectal resection. The intersphincteric space was exposed, and the internal (IAS) and external anal sphincter (EAS) were identified. Electromyography of both sphincters was performed with bipolar needle electrodes. Intermittent bipolar electric stimulation of the inferior hypogastric plexus and the pelvic splanchnic nerves was carried out bilaterally. The recorded signals were analyzed in its frequency spectrum. In all animals, electromyographic recordings of IAS and EAS were successful. Intraoperative nerve stimulation resulted in a sudden amplitude increase in the time-based electromyographic signals of IAS (1.0 (0.5-9.0) μV vs. 4.0 (1.0-113.0) μV) and EAS (p < 0.001). The frequency spectrum of IAS in the resting state ranged from 0.15 to 5 Hz with highest activity in median at 0.77 Hz (46 cycles/min). Pelvic nerve stimulation resulted in an extended spectrum ranging from 0.15 to 20 Hz. EAS signals showed higher frequencies mainly in a range of 50 to 350 Hz. However, after muscle relaxation with pancuronium bromide, only the low frequency spectrum of the IAS signals was still present. Intraoperative verification of IAS function by stimulation of pelvic autonomic nerves is possible. The IAS electromyographic response could be used to monitor pelvic autonomic nerve preservation.

    The supplementary motor area (SMA) has been implicated in many aspects of movement preparation and execution. In addition to motor roles, the SMA is responsive to somesthetic stimuli though it is unclear exactly what role the SMA plays in a somatosensory network. It is the purpose of this study to assess how continuous theta burst stimulation (cTBS) of the SMA affects both somatosensory (SEPs) and motor evoked potentials (MEPs) and if cTBS leads to alterations in tactile perception thresholds of the index fingertip. In experiment 1, cTBS was delivered over scalp sites FCZ (SMA stimulation) (n = 10) and CZ (control stimulation) (n = 10) in separate groups for 40 s (600 pulses) at 90% of participants' resting motor threshold. For both groups, median nerve SEPs were elicited from the right wrist at rest via electrical stimulation (0.5 ms pulse) before and at 10 min intervals post-cTBS out to 30 min (t = pre, 10, 20, and 30 min). Subjects' perceptual thresholds were assessed at similar time intervals as the SEP data using a biothesiometer (120 Hz vibration). In experiment 2 (n = 10) the effect of cTBS to SMA upon single and paired-pulse MEP amplitudes from the right first dorsal interosseous (FDI) was assessed. cTBS to scalp site FCZ (SMA stimulation) reduced the frontal N30 SEP and increased tactile perceptual thresholds 30 min post-stimulation. However, parietal SEPs and MEP amplitudes from both single and paired-pulse stimulation were unaffected at all time points post-stimulation. cTBS to stimulation site CZ (control) did not result in any physiological or behavioral changes. These data demonstrate cTBS to the SMA reduces the amplitude of the N30 coincident with an increase in vibration sensation threshold but does not affect primary somatosensory or motor cortex excitability. The SMA may play a significant role in a somatosensory tactile attention network. Copyright © 2013 Elsevier Inc. All rights reserved.

    Long persisting antigenic stimulation at immunogenic levels leads to a profound inhibition of antibody formation. With Brucellus abortus, there is first a brief and high IgM response. IgG antibody titres remain at a low level for some days, and then begin a slow and progressive increase, leading to a rather persistent maximum, and finally after about 300 days, to the state of inhibition. When the same total dose is given with monthly intervals, the effect is quite different, with similar IgM and IgG peaks being observed after each dose. The inhibited animals respond moderately to a ten-fold higher antigen dose, and only with IgG. Six months after interruption of the persistent antigenic stimulus, a strong response can be obtained after a new antigenic stimulation, with a substantial proportion of IgM. It is concluded that persistent antigenic stimulation plays a major role in the change from IgM to IgG synthesis. PMID:4212089

    To optimize the infrared laser wavelength and optical nerve stimulation (ONS) parameters for both deep and rapid subsurface cavernous nerve (CN) stimulation in a rat model, in vivo. A 150-mW, 1490-nm diode laser providing an optical penetration depth (OPD) of 518 μm in water was operated in continuous-wave mode during stimulation of the CNs in 8 rats for 15 seconds irradiation time through a custom-built, single-mode fiber optic probe capable of producing a collimated, 1-mm diameter laser beam. Successful ONS was judged by an intracavernous pressure response in the rat penis. Subsurface ONS at 1490 nm was also compared with previous studies using 1455 nm and 1550 nm near-infrared diode laser wavelengths. Subsurface ONS of the rat CN was successful through fascia layers with a thickness up to 380 μm using an incident laser power of ∼50 mW. Intracavernous pressure response times as short as 4.6 ± 0.2 seconds were recorded using higher laser powers below the nerve damage threshold. The 1490-nm diode laser represents a compact, low cost, high power, and high quality infrared light source for use in ONS. This wavelength provides deeper penetration than 1455-nm diode laser and more rapid and efficient nerve stimulation than 1550-nm diode laser. Copyright © 2013 Elsevier Inc. All rights reserved.

    Repetitive transcranial magnetic stimulation (rTMS) applied over the right posterior parietal cortex (PPC) in healthy participants has been shown to trigger a significant rightward shift in the spatial allocation of visual attention, temporarily mimicking spatial deficits observed in neglect. In contrast, rTMS applied over the left PPC triggers a weaker or null attentional shift. However, large interindividual differences in responses to rTMS have been reported. Studies measuring changes in brain activation suggest that the effects of rTMS may depend on both interhemispheric and intrahemispheric interactions between cortical loci controlling visual attention. Here, we investigated whether variability in the structural organization of human white matter pathways subserving visual attention, as assessed by diffusion magnetic resonance imaging and tractography, could explain interindividual differences in the effects of rTMS. Most participants showed a rightward shift in the allocation of spatial attention after rTMS over the right intraparietal sulcus (IPS), but the size of this effect varied largely across participants. Conversely, rTMS over the left IPS resulted in strikingly opposed individual responses, with some participants responding with rightward and some with leftward attentional shifts. We demonstrate that microstructural and macrostructural variability within the corpus callosum, consistent with differential effects on cross-hemispheric interactions, predicts both the extent and the direction of the response to rTMS. Together, our findings suggest that the corpus callosum may have a dual inhibitory and excitatory function in maintaining the interhemispheric dynamics that underlie the allocation of spatial attention. SIGNIFICANCE STATEMENT The posterior parietal cortex (PPC) controls allocation of attention across left versus right visual fields. Damage to this area results in neglect, characterized by a lack of spatial awareness of the side of space

    One of the most important trends in intraoperative neural monitoring (IONM) in thyroid surgery is currently the real-time monitoring of the vagus nerve (VN) in order to prevent recurrent laryngeal nerve (RLN) iatrogenic damages. Notably, continuous intraoperative neuromonitoring (C-IONM) seems to be superior to intermitted intraoperative neural monitoring (I-IONM) because it enhances standardization by permanent vagus nerve (VN) stimulation, and it provides entire and constant RLN function monitoring as the surgeon dissects and removes the thyroid gland. It also has to be highlighted that the surgical maneuvers for the automatic periodic stimulating (APS) placement must be accurate and standardized in order to avoid a potential iatrogenic morbidity on the VN function. We recommend the experienced surgeon be very careful in each step, with cautious dissection. With this review article we provide a comprehensive analyses of C-IONM technique with the APS accessory for conventional and endoscopic thyroid surgery.

  14. Dopamine Dynamics during Continuous Intracranial Self-Stimulation: Effect of Waveform on Fast-Scan Cyclic Voltammetry Data

    PubMed Central

    2016-01-01

    The neurotransmitter dopamine is heavily implicated in intracranial self-stimulation (ICSS). Many drugs of abuse that affect ICSS behavior target the dopaminergic system, and optogenetic activation of dopamine neurons is sufficient to support self-stimulation. However, the patterns of phasic dopamine release during ICSS remain unclear. Early ICSS studies using fast-scan cyclic voltammetry (FSCV) rarely observed phasic dopamine release, which led to the surprising conclusion that it is dissociated from ICSS. However, several advances in the sensitivity (i.e., the use of waveforms with extended anodic limits) and analysis (i.e., principal component regression) of FSCV measurements have made it possible to detect smaller, yet physiologically relevant, dopamine release events. Therefore, this study revisits phasic dopamine release during ICSS using these tools. It was found that the anodic limit of the voltammetric waveform has a substantial effect on the patterns of dopamine release observed during continuous ICSS. While data collected with low anodic limits (i.e., +1.0 V) support the disappearance of phasic dopamine release observed in previous investigation, the use of high anodic limits (+1.3 V, +1.4 V) allows for continual detection of dopamine release throughout ICSS. However, the +1.4 V waveform lacks the ability to resolve narrowly spaced events, with the best balance of temporal resolution and sensitivity provided by the +1.3 V waveform. Ultimately, it is revealed that the amplitude of phasic dopamine release decays but does not fully disappear during continuous ICSS. PMID:27548680

    The dorsolateral prefrontal cortex (DLPFC) plays a key role in working memory. Evidence indicates that transcranial magnetic stimulation (TMS) over the DLPFC can interfere with working memory performance. Here we investigated for how long continuous theta-burst stimulation (cTBS) over the DLPFC decreases working memory performance and whether the effect of cTBS on performance depends on working memory load. Forty healthy young subjects received either cTBS over the left DLPFC or sham stimulation before performing a 2-, and 3-back working memory letter task. An additional 0-back condition served as a non-memory-related control, measuring general attention. cTBS over the left DLPFC significantly impaired 2-back working memory performance for about 15 min, whereas 3-back and 0-back performances were not significantly affected. Our results indicate that the effect of left DLPFC cTBS on working memory performance lasts for roughly 15 min and depends on working memory load. PMID:25781012

    Interstitial fluid flow may mediate skeletal remodeling in response to mechanical loading. Because nitric oxide (NO) has been shown to be an osteoblast mitogen and inhibitor of osteoclastic resorption, we investigated and characterized the role of fluid shear on the release of NO in osteoblasts. Rat calvarial cells in a stationary culture produced undetectable levels of NO. Fluid shear stress (6 dyn/cm2) rapidly increased NO release rate to 9.8 nmol.h-1.mg protein-1 and sustained this production for 12 h of exposure to flow. Cytokine treatment also induced NO synthesis after a 12-h lag phase of zero production, followed by a production rate of 0.6 nmol.h-1.mg protein-1. Flow-induced NO production was blocked by the NO synthase (NOS) inhibitor NG-amino-L-arginine, but not by dexamethasone, which suggests that the flow stimulated a constitutive NOS isoform. This is the first time that a functional constitutively present NOS isoform has been identified in osteoblasts. Moreover, fluid flow represents the most potent stimulus of NO release in osteoblasts reported to date. Fluid flow-induced NO production may therefore play a primary role in bone maintenance and remodeling.

    A review of research into stimulated Brillouin scattering (SBS) phase conjugation and beam cleanup conducted at the Air Force Institute of Technology is presented. CW phase conjugation was demonstrated using SBS in short lengths of multi-mode, step-index fiber. A fidelity of 0.8 was achieved using a 0.06-NA fiber of 40 m length and a 0.13-NA fiber at 15 m length. In modeling and experiment, the fidelity declined as fiber length or numerical aperture increased. A relationship was established empirically between step-index fiber parameters and the phase conjugation fidelity. In addition, increased fidelity was related to an increase in the effective Brillouin gain coefficient in step-index fibers. Beam cleanup was observed in both graded-index and step-index fibers. The Stokes beam generated in long, multimode, graded-index fibers was analyzed using spatial and phase methods and found to be a low-order mode of the fiber instead of a phase conjugate of the pump. SBS in long, graded-index fibers was used to combine multiple beams and to improve the beam quality of a single aberrated beam.

  1. Adaptation of Continuous Intraoperative Vagus Nerve Stimulation for Monitoring of Recurrent Laryngeal Nerve During Minimally Invasive Esophagectomy.

    Esophagectomy has risk of recurrent laryngeal nerve (RLN) injury. Conventional nerve monitoring has been used to help identify and protect the RLN. A new concept of continuous intraoperative nerve monitoring (CIONM) by stimulation of the ipsilateral vagus nerve has been used in thyroidectomy. The current report describes adapting the CIONM method for use in video-assisted thoracoscopic (VATS) esophagectomy. The nerve monitor employed is NIM 3.0 with automatic periodic stimulation (Medtronics Inc., USA). Patient is intubated with NIM contact-reinforced EMG endotracheal tube (Medtronics Inc., USA). The operation starts with a left lower neck incision, and the stimulating electrode is secured around the left vagus nerve. The patient is then turned to the left lateral position for VATS esophagectomy. CIONM of the left RLN is achieved by regular stimulation of the left vagus nerve, and intact nerve conduction is detected by the electromyography (EMG) of the left vocalis muscle. The alarm is set to activate when EMG amplitude reduces by 50% or latency prolongs by 10%. Initial experience of ten cases showed that a mean time of 35 min was required to complete the electrode insertion in the neck. There was one event in which there was more than 50% reduction of EMG amplitude that persisted but the patient had no vocal cord paralysis after operation. In another patient, the EMG reduced by 75% and persisted. The patient had temporary vocal cord paralysis. CIONM is feasible during VATS esophagectomy and can alert the surgeon of imminent injury to the RLNs, thereby preventing permanent injury.

    When lifting objects of different mass, humans scale grip force according to the expected mass. In this context, humans are able to associate a sensory cue, such as a colour, to a particular mass of an object and link this association to the grip forces necessary for lifting. Here, we study the role of the dorsal premotor cortex (PMd) in setting-up an association between a colour cue and a particular mass to be lifted. Healthy right-handed subjects used a precision grip between the index finger and thumb to lift two different masses. Colour cues provided information about which of the two masses subjects would have to lift. Subjects first performed a series of lifts with the right hand to establish a stable association between a colour cue and a mass, followed by 20sec of continuous high frequency repetitive trancranial magnetic stimulation using a recently developed protocol (continuous theta-burst stimulation, cTBS) over (i) the left primary motor cortex, (ii) the left PMd and (iii) the left occipital cortex to be commenced by another series of lifts with either the right or left hand. cTBS over the PMd, but not over the primary motor cortex or O1, disrupted the predictive scaling of isometric finger forces based on colour cues, irrespective of whether the right or left hand performed the lifts after the stimulation. Our data highlight the role of the PMd to generalize and maintain associative memory processes relevant for predictive control of grip forces during object manipulation.

  3. Open crack depth sizing by multi-speed continuous laser stimulated lock-in thermography

    Boué, C.; Holé, S.

    2017-06-01

    A crack located in the thermal diffusion zone of a heat source behaves like a thermal barrier modifying the heat diffusion. For a moving continuous source, the sample surface is heated on a little area near the crack for a duration which depends on the speed of the thermal source. A lock-in process synchronized by the displacement of the continuous heat source along the crack is studied. The thermal signature of the crack is extracted via a space operator applied to the amplitude and the phase of surface temperature images for various speeds of the thermal source. With the technical solution presented in this article, the thermal signature images are analysed according to a length representative of the thermal diffusion length to give a local evaluation of the crack depth (around 3 mm at the maximum) for crack lengths of about few centimetres long. The multi-speed lock-in thermography approach is initially studied with finite element method simulations. Experimental tests using an infra-red camera validate the method in a second part. The results do not depend on the heating source if its power is sufficient to produce a temperature rise detectable by an infra-red camera. The depth estimations are obtained independently of the crack width and heat source trajectory. The multi-speed lock-in thermography is a method without contact, without sample preparation, non-polluting, non-destructive and with simple optical adjustments.

  4. Bimodal Modulation and Continuous Stimulation in Optical Imaging to Map Direction Selectivity

    2009-01-01

    In the visual system, neurons with similar functional properties such as orientation and direction selectivity are clustered together to form modules. Optical imaging recordings in combination with episodic paradigms have been previously used to estimate direction selectivity, a fundamental property of visual neurons. The major drawback of the episodic approach is that the extraction of the signal from various forms of physiological noise is difficult, leading to a poor estimation of direction. Recent work, based on periodic stimulation and Fourier decomposition improved the extraction of periodic stimulus responses from noise and thus, reduced the recording time considerably. Given the success of this new paradigm in mapping orientation, the present study evaluated its reliability to measure direction selectivity in the visual cortex of anesthetised cats. Here, a model that exploits the harmonics of the Fourier decomposition is proposed where the first harmonic is related to direction responses, and the second to orientation. As expected, the first harmonic was absent when a static stimulus was presented. Contrarily, the first harmonic was present when moving stimuli were presented and the amplitude was greater with random dots kinematograms than with drifting gratings. The phase of the first harmonic showed a good agreement with direction preference measured by episodic paradigm. The ratio of the first/the second harmonic amplitude, related to a direction index, was weaker in fracture. It was also weaker in areas of the ventral pathway (areas 17 and 21a) where direction selectivity is known to be reduced. These results indicate that a periodic paradigm can be easily used to measure specific parameters in optical signals, particularly in situations when short acquisition periods are needed.

  5. Continuous functions determined by spike trains of a neuron subject to stimulation.

    PubMed

    Awiszus, F

    1988-01-01

    Several ways of estimating a continuous function from the spike train output of a neuron subjected to repeated stimuli are compared: (i) the probability of firing function estimated by a PST-histogram (ii) the rate of discharge function estimated by a "frequencygram" (Bessou et al. 1968) and (iii) the interspike-interval function which is introduced in this paper. For a special class of neuronal responses, called deterministic, these functions may be expressed in terms of each other. It is shown that the current clamped Hodgkin-Huxley model of an action potential encoding membrane (Hodgkin and Huxley 1952) is able to generate such deterministic responses. As an experimental example, a deterministic response of a primary muscle spindle afferent is used to demonstrate the estimation of the functions. Interpretability and numerical estimatability of these spike train describing functions are discussed for deterministic neuronal responses.

    Although the suppression of sympathetic activity is an essential mission for the current heart failure treatment strategy, little is known about the relationship between the rotation speed setting and autonomic nervous activity during continuous-flow left ventricular assist device (LVAD) treatment. We evaluated 23 adult patients with sinus rhythm (36 ± 13 years) who had received continuous-flow LVAD and been followed at our institute between March 2013 and August 2014. Heart rate variability measurement was executed along with hemodynamic study at 3 rotation speeds (low, middle, and high) at 5 weeks after LVAD implantation. Lower rotation speed was associated with higher ratio of low-frequency over high-frequency spectral level (LF/HF), representing enhanced sympathetic activation (p < 0.05 by repeated analyses of variance). Among hemodynamic parameters, cardiac index was exclusively associated with LFNU = LF/(LF + HF), representing relative sympathetic activity over parasympathetic one (p < 0.05). After 6 months LVAD support at middle rotation speed, 19 patients with higher LFNU eventually had higher plasma levels of B-type natriuretic peptide and achieved less LV reverse remodeling. A logistic regression analysis demonstrated that lower LFNU was significantly associated with improvement of LV reverse remodeling (p = 0.021, odds ratio 0.903) with a cut-off level of 55 % calculated by the ROC analysis (AUC 0.869). In conclusion, autonomic activity can vary in various rotation speeds. Patients with higher LFNU may better be controlled at higher rotation speed with the view point to suppress sympathetic activity and achieve LV reverse remodeling.

This is a classical problem of signal recovery which is of paramount importance in inertial confinement fusion. To accomplish this task, we develop a tractable algorithm based on continuous basis pursuit and reweighted ℓ1-minimization. By modeling the observed signals as superposition of scale time-shifted copies of theoretical waveform, structured noise, and unstructured noise on a finite time interval, a sparse optimization problem is obtained. We propose to solve this problem through an iterative procedure that alternates between convex optimization to estimate the amplitude, and local optimization to estimate the dictionary. The performance of the method was evaluated both numerically and experimentally. Numerically, we recovered theoretical signals embedded in increasing amounts of unstructured noise and compared the results with those obtained through popular denoising methods. We also applied the proposed method to a set of actual experimental data acquired from the Shenguang-II laser whose energy was below the detector noise-equivalent energy. Both simulation and experiments show that the proposed method improves the signal recovery performance and extends the dynamic detection range of detectors.

    Similar to muscles, the intestine is also insulin resistant in obese subjects and subjects with impaired glucose tolerance. Exercise training improves muscle insulin sensitivity, but its effects on intestinal metabolism are not known. We studied the effects of high intensity interval training (HIIT) and moderate intensity continuous training (MICT) on intestinal glucose and free fatty acid uptake from circulation in humans. Twenty-eight healthy middle-aged sedentary men were randomized for two weeks of HIIT or MICT. Intestinal insulin-stimulated glucose uptake and fasting free fatty acid uptake from circulation were measured using positron emission tomography and [(18)F]FDG and [(18)F]FTHA. In addition, effects of HIIT and MICT on intestinal Glut2 and CD36 protein expression were studied in rats. Training improved aerobic capacity (p=0.001) and whole-body insulin sensitivity (p=0.04), but not differently between HIIT and MICT. Insulin-stimulated glucose uptake increased only after the MICT in the colon [HIIT=0%; MICT=37%] (p=0.02 for time*training) and tended to increase in the jejunum [HIIT=-4%; MICT=13%] (p=0.08 for time*training). Fasting free fatty acid uptake decreased in the duodenum in both groups [HIIT=-6%; MICT=-48%] (p=0.001 time) and tended to decrease in the colon in the MICT group [HIIT=0%; MICT=-38%] (p=0.08 for time*training). In rats, both training groups had higher Glut2 and CD36 expression compared to control animals. This study shows that already two weeks of MICT enhances insulin-stimulated glucose uptake while both training modes reduce fasting free fatty acid uptake in the intestine in healthy middle-aged men, providing an additional mechanism by which exercise training can improve whole body metabolism.

    The present study examines the influence of primary somatosensory cortex (SI) on corticospinal excitability within primary motor cortex (M1) using repetitive transcranial magnetic stimulation. Two groups of subjects participated and both received continuous theta-burst stimulation (cTBS) over SI. One group received cTBS oriented to induce anterior-to-posterior (AP) followed by posterior-to-anterior (PA) current flow in the cortex and the other group received cTBS in the opposite direction (PA-AP). Motor evoked potentials (MEPs) were measured from the first dorsal interosseous muscle of the left and right hand before and at three time points (5, 25, 45 min) following cTBS over left-hemisphere SI. CTBS over SI in the AP-PA direction increased contralateral MEPs at 5 and 45 min with a near significant increase at 25 min. In contrast, PA-AP cTBS decreased contralateral MEPs at 25 min. We conclude that cTBS over SI modulates neural output directed to the hand with effects that depend on the direction of induced current.

    Motor complications impair quality of life and cause severe disability in patients with advanced Parkinson's disease (PD). Since they are often refractory to medical therapy, interventional therapies have been developed, which can provide a considerable reduction of daily off-time and dopaminergic dyskinesias. Continuous dopaminergic drug delivery (CDD) is based on the steady stimulation of striatal dopamine receptors by subcutaneous apomorphine or duodenal L: -DOPA infusions via portable minipumps. Advances in the understanding of basal ganglia functioning and in neurosurgical, electrophysiological and neuroimaging techniques have led to a renaissance of neurosurgery for advanced PD. Deep brain stimulation of the subthalamic nucleus (STN-DBS) is the most invasive procedure promising great benefit and the highest level of independency for suitable patients, but is definitely associated with surgical risks and DBS-related side effects. Each of these more or less invasive therapy options has its own profile, and a thorough consideration of its advantages and drawbacks for the individual situation is mandatory. In this paper, we summarize relevant facts for this decision and provide some guidelines for a responsible counseling of eligible patients.

    In 1993, a surgical protocol for dynamic upper airway reconstruction in patients with obstructive sleep apnea (OSA) was published, and it became commonly known as the Stanford phase 1 and 2 sleep surgery protocol. It served as a platform on which research and clinical studies have continued to perfect the surgical care of patients with OSA. However, relapse is inevitable in a chronic condition such as OSA, and a subset of previously cured surgical patients return with complaints of excessive daytime sleepiness. This report describes a patient who was successfully treated with phase 1 and 2 operations more than a decade previously. He returned at 65 years of age with relapse of moderate OSA, and after workup with polysomnography and drug-induced sleep endoscopy, he underwent upper airway stimulation of the hypoglossal nerve that resulted in a cure of OSA. This case shows why upper airway stimulation is an appropriate option for patients with OSA relapse, after previously successful maxillomandibular advancement.

    A variety of lymphoid cell populations were examined in terms of their ability to replicate vesicular stomatitis virus (VSV), a lytic, RNA-containing virus maturing at the cell surface. The number of cells capable of producing VSV was estimated in terms of infectious centers by the virus plaque assay (VPA), and morphologically by electron microscopy (EM). The lymphoid cells examined in this study included: (a) lymph node cells from delayed hypersensitive guinea pigs stimulated by specific antigen, (b) mouse spleen cells activated by selective bone marrow-derived (B) cell and thymus derived (T) cell mitogens, and (c) cells of human and murine continuous lymphoblastoid or lymphoma lines. In unstimulated cultures of guinea pig lymph node cells there is a background of approximately 1 in 1,000 cells which produces VSV; in purified protein derivative (PPD)-stimulated cultures the number of cells producing virus was 1.6% in the VPA and 1.9% by EM. These cells were large lymphocytes with some morphological features of transformed lymphocytes but were not typical blast cells. A few macrophages were associated with virus in both stimulated and control cultures. These observations indicate that (a) cells responsive to antigens, as detected by a marker virus, were lymphocytes; (b) cells other than lymphocytes (macrophages) were capable of replicating VSV even without antigenic stimulation; and (c) the correlation of results obtained by VPA and morphologic examination was usually quite good. Of the total number of mouse spleen cells stimulated with concanavalin (Con A), a T cell mitogen, 4.5 (EM)–5.7% (VPA) were associated with VSV. These were characteristic transformed lymphocytes, similar to phytohemagglutinin (PHA)-stimulated human lymphocytes. In contrast Escherichia coli lipopolysaccharide (LPS)-treated mouse spleen cultures contained lower numbers of virus plaque-forming cells. The majority of such cells associated with virus displayed extensive rough endoplasmic

    The purpose of this study was to assess the safety, feasibility and efficacy of continuous theta-burst stimulation (cTBS) combined with intensive occupational therapy (OT) for upper limb hemiparesis after stroke. Ten patients with history of stroke and upper limb hemiparesis (age 62.0 ± 11.1 years, time since stroke 95.7 ± 70.2 months, mean ± SD) were studied. Each patient received 13 sessions, each comprising 160 s of cTBS applied to the skull on the area of the non-lesional hemisphere (using a 70-mm figure-8 coil, three pulse bursts at 50 Hz, repeated every 200 ms, i.e., 5 Hz, with total stimulation of 2,400 pulses), followed by intensive OT (comprising 120-min one-to-one training and 120-min self-training) during 15-day hospitalization. The motor function of the affected upper limb was evaluated by Fugl-Meyer Assessment (FMA) and Wolf Motor Function Test (WMFT) on the days of admission and discharge. All patients completed the 15-day protocol without any adverse effects. Treatment significantly increased the FMA score (from 46.6 ± 8.7 to 51.6 ± 8.2 points, p < 0.01) and shortened the log performance time of WMFT (from 2.5 ± 1.1 to 2.2 ± 1.2 s, p < 0.01). The 15-day protocol of cTBS combined with intensive OT is a safe and potentially useful therapeutic modality for upper limb hemiparesis after stroke.

    Objective. Deep brain stimulation (DBS) of the superolateral branch of the medial forebrain bundle (MFB) has provided rapid and dramatic reduction of depressive symptoms in a clinical trial. Early intracranial self-stimulation experiments of the MFB suggested detrimental side effects on the animals' health; therefore, the current study looked at the viability of chronic and continuous MFB-DBS in rodents, with particular attention given to welfare issues and identification of stimulated pathways. Methods. Sprague-Dawley female rats were submitted to stereotactic microelectrode implantation into the MFB. Chronic continuous DBS was applied for 3–6 weeks. Welfare monitoring and behavior changes were assessed. Postmortem histological analysis of c-fos protein expression was carried out. Results. MFB-DBS resulted in mild and temporary weight loss in the animals, which was regained even with continuing stimulation. MFB-DBS led to increased and long-lasting c-fos expression in target regions of the mesolimbic/mesocortical system. Conclusions. Bilateral continuous chronic MFB-DBS is feasible, safe, and without impact on the rodent's health. MFB-DBS results in temporary increase in exploration, which could explain the initial weight loss, and does not produce any apparent behavioral abnormalities. This platform represents a powerful tool for further preclinical investigation of the MFB stimulation in the treatment of depression. PMID:25960609

    Converging evidence suggests an association between spatial and music domains. A cerebellar role in music-related information processing as well as in spatial-temporal tasks has been documented. Here, we investigated the cerebellar role in the association between spatial and musical domains, by testing performances in embodied (EMR) or abstract (AMR) mental rotation tasks of subjects listening Mozart Sonata K.448, which is reported to improve spatial-temporal reasoning, in the presence or in the absence of continuous theta burst stimulation (cTBS) of the left cerebellar hemisphere. In the absence of cerebellar cTBS, music listening did not influence either MR task, thus not revealing a "Mozart Effect". Cerebellar cTBS applied before musical listening made subjects faster (P = 0.005) and less accurate (P = 0.005) in performing the EMR but not the AMR task. Thus, cerebellar inhibition by TBS unmasked the effect of musical listening on motor imagery. These data support a coupling between music listening and sensory-motor integration in cerebellar networks for embodied representations.

    The purpose of this study was to investigate the effect of systematic variations in stimulation rate and number of channels on speech understanding in 13 patients with cochlear implants who used the continuous interleaved sampling speech coding strategy. Reducing the stimulation rate from 1,515 to 1,730 pulses per second per channel to 600 pulses per second per channel resulted in decreased overall performance; the understanding of monosyllables and consonants was more affected than the understanding of vowels. Reducing the number of active channels below 7 or 8 channels decreased speech understanding; the identification of vowels and monosyllables was most affected. We conclude that vowel recognition with the continuous interleaved sampling strategy relies on spectral cues more than on temporal cues, increasing with the number of active channels, whereas consonant recognition is more dependent on temporal cues and stimulation rate.

    Adjustments to movement in response to changes in our surroundings are common in everyday behavior. Previous research has suggested that the left pre-motor cortex (PMC) is specialized for the temporal control of movement and may play a role in temporal error correction. The aim of this study was to determine the role of the left PMC in sensorimotor timing and error correction using theta burst transcranial magnetic stimulation (TBS). In Experiment 1, subjects performed a sensorimotor synchronization task (SMS) with the left and the right hand before and after either continuous or intermittent TBS (cTBS or iTBS). Timing accuracy was assessed during synchronized finger tapping with a regular auditory pacing stimulus. Responses following perceivable local timing shifts in the pacing stimulus (phase shifts) were used to measure error correction. Suppression of the left PMC using cTBS decreased timing accuracy because subjects tapped further away from the pacing tones and tapping variability increased. In addition, error correction responses returned to baseline tap-tone asynchrony levels faster following negative shifts and no overcorrection occurred following positive shifts after cTBS. However, facilitation of the left PMC using iTBS did not affect timing accuracy or error correction performance. Experiment 2 revealed that error correction performance may change with practice, independent of TBS. These findings provide evidence for a role of the left PMC in both sensorimotor timing and error correction in both hands. We propose that the left PMC may be involved in voluntarily controlled phase correction responses to perceivable timing shifts.

    Spatial neglect is modeled on an imbalance of interhemispheric inhibition (IHI); however evidence is emerging that it may not explain neglect in all cases. The aim of this study was to investigate the IHI imbalance model of visual neglect in healthy adults, using paired pulse transcranial magnetic stimulation to probe excitability of projections from posterior parietal cortex (PPC) to contralateral primary motor cortex (M1) bilaterally. Motor-evoked potentials (MEPs) were recorded from the first dorsal interossei and facilitation was determined as ratio of conditioned to non-conditioned MEP amplitude. A laterality index reflecting the balance of excitability between the two hemispheres was calculated. A temporal order judgment task (TOJ) assessed visual attention. Continuous theta-burst stimulation was used to transiently suppress right parietal cortex activity and the effect on laterality and judgment task measured, along with associations between baseline and post stimulation measures. Stimulation had conflicting results on laterality, with most participants demonstrating an effect in the negative direction with no decrement in the TOJ task. Correlation analysis suggests a strong association between laterality direction and degree of facilitation of left PPC-to right M1 following stimulation (r=.902), with larger MEP facilitation at baseline demonstrating greater reduction (r=-.908). Findings indicate there was relative balance between the cortices at baseline but right PPC suppression did not evoke left PPC facilitation in most participants, contrary to the IHI imbalance model. Left M1 facilitation prior to stimulation may predict an individual's response to continuous theta-burst stimulation of right PPC.

    Aim The aim of this study was to assess the effect of continuous and intermittent electrical transcutaneous nerve stimulation on the perception of pain in patients with burns of different types. Materials and methods A pilot study was conducted in 14 patients (age 30.9±7.5 years) with second- and third-degree burns of different types. The burn types included electrical, fire/flame, and chemical. All patients received continuous and intermittent electrical transcutaneous nerve stimulation sessions three times per week for 4 weeks. Each session had a duration of 30 minutes. A pair of electrodes were placed around the burn. The primary efficacy endpoint was the perception of pain assessed by a visual analog scale at baseline and at the 30th day. Results A significant reduction of pain perception was reported (8.0±1.7 vs 1.0±0.5; P=0.027) by all patients after electrical stimulation therapy. There were no reports of adverse events during the intervention period. Conclusion Electrical stimulation could be a potential nonpharmacological therapeutic option for pain management in burn patients. PMID:26719723

    Obstructive sleep apnoea (OSA) is associated with a variety of adverse health outcomes. Continuous positive airway pressure (CPAP) is considered first-line treatment for sleep apnoea patients, but there are few studies on oral health in patients with OSA who are using CPAP. This study aimed to estimate the prevalence of oral symptoms and interest in alternative treatments such as oral appliance (OA) therapy in CPAP users. A questionnaire was used to ascertain oral health including denture use, oral symptoms at present and since the start of CPAP, and interest in OA therapy. Relevant demographic and clinical data were collected from medical records. The 744 participants who completed the questionnaire had following characteristics (mean ± standard deviation): age (55.1 ± 12.9 years); apnoea-hypopnoea index (40.9 ± 23.2/h); body mass index (27.9 ± 5.2 kg/m(2) ) and length of CPAP usage (49.1 ± 30.7 months); halitosis (30.4%); and gingival bleeding (27.5%). Nearly half (44.6%) complained of dry mouth since beginning CPAP therapy. Patients with diabetes were older (57.8 ± 11.9 vs. 54.2 ± 12.8 years), had a higher rate of denture use (28.3 vs. 19.0%), more dental clinic visits (71.4 vs. 58.7%) and more oral symptoms (50.0 vs. 38.2%) than non-diabetes patients (p < 0.05). Thirty-eight per cent of subjects were interested in OA therapy. This study exhibited that almost 40% of CPAP users had oral symptoms. In particular, OSA patients with diabetes may be at high risk of oral disease. © 2015 John Wiley & Sons A/S and The Gerodontology Association. Published by John Wiley & Sons Ltd.

    Polyhydroxyalkanoates (PHAs) are one of the most researched family of biodegradable polymers based on renewable materials due to their thermoplastic nature and moisture resistance. The present study was targeted to investigate the preparation and characterization of poly(3-hydroxybutyrate) (PHB) films obtained through the electrospinning technique. To convert them into continuous films and then to increase their application interest in packaging, the electrospun fiber mats were subsequently post-processed by different physical treatments. Thus, the effect of annealing time and cooling method on morphology, molecular order, thermal, optical, mechanical, and barrier properties of the electrospun submicron PHB fibers was studied. Annealing at 160°C, well below the homopolyester melting point, was found to be the minimum temperature at which homogeneous transparent films were produced. The film samples that were cooled slowly after annealing showed the lowest permeability to oxygen, water vapor, and limonene. The optimally post-processed electrospun PHB fibers exhibited similar rigidity to conventional compression-molded PHA films, but with enhanced elongation at break and toughness. Films made by this electrospinning technique have many potential applications, such as in the design of barrier layers, adhesive interlayers, and coatings for fiber- and plastic-based food packaging materials.

    In natural life pain automatically draws attention towards the painful body part suggesting that it interacts with different attentional mechanisms such as visual attention. Complex regional pain syndrome (CRPS) patients who typically report on chronic distally located pain of one extremity may suffer from so-called neglect-like symptoms, which have also been linked to attentional mechanisms. The purpose of the study was to further evaluate how continuous pain conditions influence visual attention. Saccade latencies were recorded in two experiments using a common visual attention paradigm whereby orientating saccades to cued or uncued lateral visual targets had to be performed. In the first experiment saccade latencies of healthy subjects were measured under two conditions: one in which continuous experimental pain stimulation was applied to the index finger to imitate a continuous pain situation, and one without pain stimulation. In the second experiment saccade latencies of patients suffering from CRPS were compared to controls. The results showed that neither the continuous experimental pain stimulation during the experiment nor the chronic pain in CRPS led to an unilateral increase of saccade latencies or to a unilateral increase of the cue effect on latency. The results show that unilateral, continuously applied pain stimuli or chronic pain have no or only very limited influence on visual attention. Differently from patients with visual neglect, patients with CRPS did not show strong side asymmetries of saccade latencies or of cue effects on saccade latencies. Thus, neglect-like clinical symptoms of CRPS patients do not involve the allocation of visual attention.

    Cells in the animal early visual cortex are sensitive to contour orientations and form repeated structures known as orientation columns. At the behavioral level, there exist 2 well-known global biases in orientation perception (oblique effect and radial bias) in both animals and humans. However, their neural bases are still under debate. To unveil how these behavioral biases are achieved in the early visual cortex, we conducted high-resolution functional magnetic resonance imaging experiments with a novel continuous and periodic stimulation paradigm. By inserting resting recovery periods between successive stimulation periods and introducing a pair of orthogonal stimulation conditions that differed by 90° continuously, we focused on analyzing a blood oxygenation level-dependent response modulated by the change in stimulus orientation and reliably extracted orientation preferences of single voxels. We found that there are more voxels preferring horizontal and vertical orientations, a physiological substrate underlying the oblique effect, and that these over-representations of horizontal and vertical orientations are prevalent in the cortical regions near the horizontal- and vertical-meridian representations, a phenomenon related to the radial bias. Behaviorally, we also confirmed that there exists perceptual superiority for horizontal and vertical orientations around horizontal and vertical meridians, respectively. Our results, thus, refined the neural mechanisms of these 2 global biases in orientation perception. PMID:22661413

    In rams, artificial long days followed by continuous light stimulate testosterone secretion during the non-breeding season. The objective of this study was to determine whether artificial long days followed by continuous light could stimulate testosterone secretion in Alpine bucks as well as in those exposed to long days followed by a melatonin treatment. All bucks were kept in shaded open pens. Control males were exposed to natural photoperiod conditions (n=5). Males of the two experimental groups were exposed to 2.5 months of long days from 1 December (n=5 each). On 16 February, one group of males was exposed to 24 h of light per day until 30 June; the other group was exposed to natural variations of photoperiod and received two s.c. melatonin implants. Testicular weight was determined every 2 weeks, and the plasma testosterone concentrations once a week. In the control and the two photoperiodic-treated groups, a treatment×time interaction was detected for testicular weight and plasma testosterone concentrations (P<0.001). In control bucks, testicular weight increased from January and peaked in June, whereas in both photoperiodic-treated groups, this variable increased from January, but peaked in April, when the values were higher than in controls (P<0.05). In the control group, plasma testosterone concentrations remained low from January to June, whereas in both photoperiodic-treated groups, this variable remained low from January to March; thereafter, these levels increased in both photoperiodic-treated groups, and were higher than controls in April and May (P<0.05). We conclude that continuous light after a long-day treatment stimulate testosterone secretion in Alpine male goats during the non-breeding season as well as the long days followed by a melatonin treatment. Therefore, continuous light could replace the implants of melatonin.

    Successful identification and preservation of the cavernous nerves (CN), which are responsible for sexual function, during prostate cancer surgery, will require subsurface detection of the CN beneath a thin fascia layer. This study explores optical nerve stimulation (ONS) in the rat with a fascia layer placed over the CN. Two near-IR diode lasers (1455 nm and 1550 nm lasers) were used to stimulate the CN in CW mode with a 1-mm-diameter spot in 8 rats. The 1455 nm wavelength provides an optical penetration depth (OPD) of ~350 μm, while 1550 nm provides an OPD of ~1000 μm (~3 times deeper than 1455 nm and 1870 nm wavelengths previously tested). Fascia layers with thicknesses of 85 - 600 μm were placed over the CN. Successful ONS was confirmed by an intracavernous pressure (ICP) response in the rat penis at 1455 nm through fascia 110 μm thick and at 1550 nm through fascia 450 μm thick. Higher incident laser power was necessary and weaker and slower ICP responses were observed as fascia thickness was increased. Subsurface ONS of the rat CN at a depth of 450 μm using a 1550 nm laser is feasible.

    For predicting pain stimulation effects and avoiding damage in 1940nm laser evoked potentials (LEPs) experiments, a 2-layer finite element model (FEM-2) was constructed. A series of experiments were conducted on ex-vivo pig skin pieces to verify temperature distribution predicted by this model. Various laser powers and beam radii were employed. Experimental data of time-dependent temperature responses in different sub-skin depths and space-dependent surface temperature was recorded by thermocouple instrument. By comparing with the experimental data and model results, FEM-2 model was proved to predict temperature distributions accurately. A logarithmic relationship between laser power density and temperature increment was revealed by the results. It is concluded that power density is an effective parameter to estimate pain and damage effect. The obtained results also indicated that the proposed FEM-2 model can be extended to predict pain and damage thresholds of human skin samples and thus contribute to LEPs study. PMID:25909027

    Movement-related gating ensures that decreased somatosensory information from external stimulation reaches the cortex during movement when compared to resting levels; however, gating may be influenced by task-relevant manipulations, such that increased sensory information ascends to the cortex when information is relevant to goal-based actions. These task-relevancy effects are hypothesized to be controlled by a network involving the dorsolateral prefrontal cortex (DLPFC) based on this region's known role in selective attention, modulating the primary somatosensory cortex (S1). The purpose of the current study was first to verify task-relevancy influences on movement-related gating in the upper limb, and second to test the contribution of the DLPFC and the primary somatosensory cortex (S1) to these relevancy effects. Ten healthy participants received median nerve stimulation at the left wrist during three conditions: rest, task-irrelevant movement, and task-relevant movement. Cortical responses to median nerve stimulations were measured in the form of somatosensory evoked potentials (SEPs). The three conditions were collected on a baseline day and on two separate days following continuous theta-burst (cTBS), which transiently reduces cortical excitability, over either the contralateral S1 or DLPFC. Results demonstrated a significant interaction between stimulation and condition, with a priori contrasts revealing that cTBS over either S1 or DLPFC diminished the relevancy-based modulation of SEP amplitudes; however, the degree of this effect was different. These results indicate that DLPFC influences over S1 are involved in the facilitation of relevant sensory information during movement.

    The purpose of this study was to improve the surgical treatment of epilepsy by maximising seizure control while protecting language function. A combined process of extra-operative electrical cortical stimulation (ECS) mapping, direct ECS and intra-operative continuous language assessment was performed during complicated operative cases. Of the 24 epilepsy patients, nine had a complex relationship between the seizure onset zone and the language cortices. The combined process was used in these nine patients. In the other 15 patients, surgical resection was completed based on extra-operative ECS results alone. Evaluations were performed before and after surgery to assess language function and seizure control. The intra-operative continuous language assessment provided important information at the time of the resection. Seven extra-operative ECS positive language sites were resected without obvious language deficits in two patients. Resection was interrupted by language disturbances in an area where no extra-operative ECS positive site was identified in one patient. In three other patients, functional boundary was undefined in extra-operative ECS result, epileptogenic cortices were maximally resected during the continuous language assessment. In terms of seizure control, 18 of 24 (75%) patients reached Engel's class I, including all nine patients who underwent intra-operative continuous language assessment. One patient had minor surgery-related language deficits three months after resection. Intra-operative continuous language assessment proved to be complementary to extra-operative ECS mappings. The combination of ECS mappings and intra-operative continuous language assessment can maximise the resection of epileptogenic cortices and preserve language function in difficult cases involving the language cortex.

    The efficacy of the common practice of tracking brain dynamics using a few key regions of interest is explained via the fact that these regions are sensitive to underlying extended modes of activity, not just local dynamics. This underlines the inseparable interplay between modes and regions and reflects the reality that brain functions range from highly localized to highly extended.

    In a typical go/no-go task a single imperative stimulus is presented each trial, either a go or no-go stimulus. Participants are instructed to initiate a known response upon appearance of the go-signal and withhold the response if the no-go signal is presented. It is unclear whether the go-response is prepared in advance of the imperative stimulus in a go/no-go task. Moreover, it is unclear if inhibitory control processes suppress preparatory go-activation. The purpose of the present experiment was 1) to determine whether the go-response is prepared in advance of stimulus identification with the use of a startling acoustic stimulus (SAS), and 2) investigate the inhibitory role of the right inferior frontal gyrus (rIFG) and pre-supplementary motor area (preSMA) during the performance of a go/no-go task with the use of continuous theta burst stimulation (cTBS). The experiment consisted of three phases; a pre-cTBS phase in which participants completed a go/no-go and simple-RT task, followed by offline cTBS to temporarily deactivate either rIFG or preSMA (with a sham control), then a post-cTBS phase which was identical to the pre-cTBS phase. Results revealed that stimulation to both cortical sites impaired participants' ability to withhold movements during no-go trials. Notably, rIFG or preSMA stimulation did not affect the latency of voluntary go-responses and did not enable the SAS to involuntarily trigger responses. These findings suggest that preparation and initiation of the go-response occurs after the imperative stimulus, with the rIFG and preSMA involved in inhibiting the go-response once the stimulus is identified as a no-go signal.

    The speed-accuracy trade-off (SAT) refers to the balancing of speed versus accuracy during decision-making. SAT is very commonly investigated with perceptual decision-making tasks such as the moving dots task (MDT). The dorsolateral prefrontal cortex (DLPFC) and the pre-supplementary motor area (pre-SMA) are two brain regions considered to be involved in the control of SAT. The study tested whether the DLPFC and the pre-SMA play an essential role in the control of SAT. We hypothesized that continuous theta burst stimulation (cTBS) over the right DLPFC would primarily alter the rate of accumulation of evidence, whereas stimulation of the pre-SMA would influence the threshold for reaching a decision. Fifteen (5 females; mean age = 30, SD =5.40) healthy volunteers participated in the study. We used two versions of the MDT and cTBS over the right DLPFC, pre-SMA and sham stimulation. The drift diffusion model was fit to the behavioural data (reaction time and error rate) in order to calculate the drift rate, boundary separation (threshold) and non-decision time. cTBS over the right DLPFC decreased the rate of accumulation of evidence (i.e. the drift rate from the diffusion model) in high (0.35 and 0.5) but not in low coherence trials. cTBS over the pre-SMA changed the boundary separation/threshold required to reach a decision on accuracy, but not on speed trials. The results suggest for the first time that both the DLPFC and the pre-SMA make essential but distinct contributions to the modulation of SAT. Copyright © 2016. Published by Elsevier Inc.

    Human CD4+CD25+ regulatory T (T(R)) cells express the transcription factor forkhead box p3 (FOXP3) and have potent immunosuppressive properties. While naturally occurring T(R) cells develop in the thymus, adaptive T(R) cells develop in the periphery from naive CD4+ T cells. Adaptive T(R) cells may express cyclooxygenase type 2 (COX-2) and suppress effector T cells by a PGE(2)-dependent mechanism, which is reversible with COX inhibitors. In this study we have characterized the differentiation of naive CD4+ T cells into adaptive T(R) cells in detail during 7 days of continuous antigen stimulation. After 2 days of stimulation of CD4+CD25- T cells, the cells expressed FOXP3 and COX-2 and displayed potent immunosuppressive properties. The suppressive phenotype was present at all observed time-points from Day 2, although suppression was merely present at Day 7. The adaptive T(R) cells expressed cell surface markers consistent with an activated phenotype and secreted high levels of TGF-beta, IL-10, and PGE(2). However, the suppressive phenotype was found exclusively in cells that proliferated upon activation. These data support the notion that activation of naive CD4+ T cells leads to concomitant acquisition of effector and suppressive properties.

    The essential role of continuous antigenic stimulation in the development and differentiation of antibody-forming cells as defined in the X-Y-Z immune cell maturation scheme was examined in these studies. Mice were primed with sheep erythrocytes (SRBC) in an attempt to induce maximum immune progenitor cell conversion (X --> Y). Subsequently antigen was depleted at 1 or 4 days after priming with isologous specific antibody in order to interrupt further immune cell differentiation (Y --> Z). It was reasoned that this condition would result in depression of the functional antibody-producing cell compartment as measured in the intact mice and subsequently in enhancement of the sensitized (Y cell) compartment as measured in the spleen cell transfer system. These data were also correlated with systematic studies of the hyperplasia of the spleen germinal centers. The effect of passive antibody on the primary response to SRBC was a marked decrease indirect and indirect hemolysin-producing cells (DPFC and IPFC). However, there was a lack of correlation in the degree of antibody-mediated 19S and 7S immune cell suppression during the primary response, the DPFC being much less depressed than the IPFC. As measured in the transfer system there was an enhanced 19S sensitized cell compartment and a depressed 7S sensitized cell compartment in 1 day passively immunized mice. This was true whether or not transfers were performed 1, 2, or 4 wk after priming. Similarly, there was an enhanced 19S-sensitized cell compartment with little or no effect on the 7S-sensitized. cell compartment in 4 day passively immunized mice. These data suggest that progeny of the antigen-stimulated progenitor cells (X cell), as a consequence of lack of further antigenic stimulation, were forced into maturation arrest. These studies further demonstrate that isologous passive antibody suppresses germinal center growth regardless of whether the antibody is infused 1, 2, or 4 days after priming. In terms of

    Avoidance of the negative affective (emotional) symptoms of nicotine withdrawal (e.g., anhedonia, anxiety) contributes to tobacco addiction. Establishing the minimal nicotine exposure conditions required to demonstrate negative affective withdrawal signs in animals, as well as understanding moderators of these conditions, could inform tobacco addiction-related research, treatment, and policy. The goal of this study was to determine the minimal duration of continuous nicotine infusion required to demonstrate nicotine withdrawal in rats as measured by elevations in intracranial self-stimulation (ICSS) thresholds (anhedonia-like behavior). Administration of the nicotinic acetylcholine receptor antagonist mecamylamine (3.0 mg/kg, s.c.) on alternate test days throughout the course of a 2-week continuous nicotine infusion (3.2 mg/kg/day via osmotic minipump) elicited elevations in ICSS thresholds beginning on the second day of infusion. Magnitude of antagonist-precipitated withdrawal did not change with further nicotine exposure and mecamylamine injections, and was similar to that observed in a positive control group receiving mecamylamine following a 14-day nicotine infusion. Expression of a significant withdrawal effect was delayed in nicotine-infused rats receiving mecamylamine on all test days rather than on alternate test days. In a separate study, rats exhibited a transient increase in ICSS thresholds following cessation of a 2-day continuous nicotine infusion (3.2 mg/kg/day). Magnitude of this spontaneous withdrawal effect was similar to that observed in rats receiving a 9-day nicotine infusion. Our findings demonstrate that rats exhibit antagonist-precipitated and spontaneous nicotine withdrawal following a 2-day continuous nicotine infusion, at least under the experimental conditions studied here. Magnitude of these effects were similar to those observed in traditional models involving more prolonged nicotine exposure. Further development of these models

    Cell biology of triggering receptor expressed in myeloid cells 2, a receptor expressed in brain cells (microglia and possibly neurons and oligodendrocytes) which is responsible for a neurological and psychiatric genetic disease, polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy otherwise called the Nasu-Hakola disease, is still largely unknown. Using immortalized mouse N9 microglial cells we demonstrate that triggering receptor expressed in myeloid cells 2 is mostly distributed intracellularly in two pools: a deposit in the Golgi complex and a population of exocytic vesicles, distinct from endosomes and lysosomes, which is continuously translocated to, and recycled from the cell surface. Results with ionomycin and gamma-interferon, showing rapid and slow increases, respectively, of triggering receptor expressed in myeloid cells 2 surface density, documented that the exocytosis of the receptor-rich vesicles is regulated. Pulse labeling in the cold of surface triggering receptor expressed in myeloid cells 2 with its antibody (or Fab fragment) followed by chase at 37 degrees C showed internalization, with recovery of the antibody in endosomes and lysosomes. However, part of the receptor/antibody complex, internalized for up to 30 min chase, was recycled to the cell surface within 2 min of ionomycin stimulation, together with a fraction of the total biotinylated surface protein chased in parallel. The internalized receptor appears therefore to get access to exocytic organelles distinct from lysosomes which may resemble the exocytic vesicles of resting cells. These results document that, in microglial cells, the surface density of the triggering receptor expressed in myeloid cells 2 and thus, presumably, the response to its activation, is continuously adapted and can be greatly increased, even at rapid rate, as a function of cell activation.

    The aim of this study was to evaluate effects of electrical stimulation combined with continuous passive motion (CPM-ES) versus isometric exercise on symptoms, functional capacity, quality of life, muscle strength, knee and thigh circle measurements, and balance in knee osteoarthritis (OA). This is a randomized clinical trial. The study was done in Gulhane Military Medical Academy (GMMA) Rehabilitation Center. Forty patients with knee OA were included in this study. Participants were randomly assigned to two groups: 20 patients placed in Group 1 were treated with conventional physical therapy and CPM-ES combination; 20 patients in Group 2 were treated with conventional physical therapy and isometric exercise. Therapies were applied 3 weeks, 5 days per week. The following main outcome measures were done: values of pain (VAS was used), WOMAC, SF-36, knee and thigh circle measurements, isokinetic tests, dynamic and static balance tests were determined at baseline and after the treatment. There were no statistically significant differences in the tested variables between the groups for post-treatment values. Dynamic and static balance test improved statistically strongly significantly in both groups. The findings of this study demonstrate that knee OA patients could improve their balance function in both static and dynamic conditions after CPM-ES combination or isometric exercise therapy. The improvement might prevent knee OA patients from falling down and increase their sense of security during physical activities.

    A systematic review of the literature was conducted to identify randomized trials involving continuous dopaminergic stimulation (CDS) in PD patients with motor complications. Difference between n groups was assessed by partitioning heterogeneity and using the χ2 distribution with n-1 degrees of freedom, where n equals the number of groups. We looked for publication bias using funnel plotting, Egger's test and Begg's test. Twenty Randomized Controlled Trials (RCTs) were included. The results showed that CDS could evidently improve the Unified Parkinson's Disease Rating Scale (UPDRS) Part II (p < 0.0001), part III (P < 0.00001) and UPDRS total score (p < 0.00001). There was also a statistical discrepancy in off time reduction (p < 0.00001) and prolongation of on time (p < 0.00001) by the CDS therapy compared with control groups. Meanwhile, the results of this study showed obvious side effects in the CDS therapy compared with the placebo, especially at the expense of increased dyskinesia (23.4% vs 11.7%). The present study showed that CDS was beneficial in the treatment of PD patients with motor complications. But the incidence of the side events is more common than placebo.

    Combined continuous s.c. coadministration of macrophage-colony stimulating factor (M-CSF) plus interleukin-2 (IL-2) by osmotic pump protected mice given i.v. injections of a lethal dose of EL4 T-cell leukemia/lymphoma. Antitumor protection was significantly greater than that afforded by treatment with either cytokine alone. Since neither IL-2 receptors nor M-CSF receptors were expressed on EL4, the antitumor effect was likely attributed to murine effector cells. To determine how M-CSF+IL-2 provided this effect, we performed immunophenotypic and functional analyses as well as in vivo depletion studies of putative antitumor effector cells. Splenic phenotyping experiments revealed that the highest levels of macrophages and natural killer cells were observed in mice given the cytokine combination rather than either M-CSF or IL-2 alone. In vivo depletion of natural killer cells ablated the antitumor protective effect of M-CSF and IL-2. T-cells were also important for M-CSF+IL-2 efficacy, since adult thymectomy/T-cell depletion significantly inhibited the ability of cytokine coadministration to protect against EL4. Coadministration of the 2 cytokines significantly elevated in vivo levels of CD3+CD4+, CD3+CD8+, CD3+NK1.1+ T-cells, and CD3+CD25+ (activated) T-cells, and elevated anti-EL4 cytotoxic T-cell activity measured in vitro. Although WBC counts and fluorescence-activated cell sorter studies showed that M-CSF+IL-2 treatment significantly elevated neutrophils, s.c. delivery of granulocyte-colony stimulating factor at doses sufficient to induce neutrophilia was unable to confer anti-EL4 protection. These studies indicate that macrophages, T-cells, and natural killer cells are all important in the M-CSF+IL-2 anti-EL4 response. The superior antitumor effect of this cytokine combination along with the ability of M-CSF to diminish the toxicity of IL-2 in this model suggests that further investigations into the clinical potential of this combination treatment are warranted.

  3. Differential effects of continuous theta burst stimulation over left premotor cortex and right prefrontal cortex on modulating upper limb somatosensory input.

    Somatosensory evoked potentials (SEPs) represent somatosensory processing in non-primary motor areas (i.e. frontal N30 and N60) and somatosensory cortices (i.e. parietal P50). It is well-known that the premotor cortex (PMC) and prefrontal cortex (PFC) are involved in the preparation and planning of upper limb movements but it is currently unclear how they modulate somatosensory processing for upper limb motor control. In the current study, two experiments examined SEP modulations after continuous theta burst stimulation (cTBS) was used to transiently disrupt the left PMC (Experiment 1) and right PFC (Experiment 2). Both Experiment 1 (n=15) and Experiment 2 (n=16) used pre-post experimental designs. In both experiments participants performed a task requiring detection of varying amplitudes of attended vibrotactile (VibT) stimuli to the left index finger (D2) and execution of a pre-matched finger sequence with the right (contralateral) hand to specific VibT targets. During the task, SEPs were measured to median nerve (MN) stimulations time-locked during pre-stimulus (250 ms before VibT), early response selection (250 ms after VibT), late preparatory (750 ms after VibT) and execution (1250 ms VibT) phases. The key findings of Experiment 1 revealed significant decreases in N30 and N60 peak amplitudes after cTBS to PMC. In contrast, the results of Experiment 2, also found significant decreased N60 peak amplitudes as well as trends for increased N30 and P50 peak amplitudes. A direct comparison of Experiment 1 and Experiment 2 confirmed differential modulation of N30 peak amplitudes after PMC (gated) compared to PFC (enhanced) cTBS. Collectively, these results support that both the left PMC and right PFC have modulatory roles on early somatosensory input into non-primary motor areas, such as PMC and supplementary motor area (SMA), represented by frontal N30 and N60 SEPs. These results confirm that PMC and PFC are both part of a network that regulates somatosensory input

    Continuous stimulation of cells with insulin-like growth factors (IGFs) in G1 phase is a well established requirement for IGF-induced cell proliferation; however, the molecular components of this prolonged signaling pathway that is essential for cell cycle progression from G1 to S phase are unclear. IGF-I activates IGF-I receptor (IGF-IR) tyrosine kinase, followed by phosphorylation of substrates such as insulin receptor substrates (IRS) leading to binding of signaling molecules containing SH2 domains, including phosphatidylinositol 3-kinase (PI3K) to IRS and activation of the downstream signaling pathways. In this study, we found prolonged (>9 h) association of PI3K with IGF-IR induced by IGF-I stimulation. PI3K activity was present in this complex in thyrocytes and fibroblasts, although tyrosine phosphorylation of IRS was not yet evident after 9 h of IGF-I stimulation. IGF-I withdrawal in mid-G1 phase impaired the association of PI3K with IGF-IR and suppressed DNA synthesis the same as when PI3K inhibitor was added. Furthermore, we demonstrated that Tyr1316-X-X-Met of IGF-IR functioned as a PI3K binding sequence when this tyrosine is phosphorylated. We then analyzed IGF signaling and proliferation of IGF-IR−/− fibroblasts expressing exogenous mutant IGF-IR in which Tyr1316 was substituted with Phe (Y1316F). In these cells, IGF-I stimulation induced tyrosine phosphorylation of IGF-IR and IRS-1/2, but mutated IGF-IR failed to bind PI3K and to induce maximal phosphorylation of GSK3β and cell proliferation in response to IGF-I. Based on these results, we concluded that PI3K activity bound to IGF-IR, which is continuously sustained by IGF-I stimulation, is required for IGF-I-induced cell proliferation. PMID:22767591

    The dispersion of granules in upflow anaerobic sludge blanket (UASB) reactor represents a critical technical issue in methanolic wastewater treatment. In this study, the potentials of coupling a microbial electrolysis cell (MEC) into an UASB reactor for improving methanolic wastewater biodegradation, long-term process stability and biomethane recovery were evaluated. The results indicated that coupling a MEC system was capable of improving the overall performance of UASB reactor for methanolic wastewater treatment. The combined system maintained the comparatively higher methane yield and COD removal efficiency over the single UASB process through the entire process, with the methane production at the steady-state conditions approaching 1504.7 ± 92.2 mL-CH4 L(-1)-reactor d(-1), around 10.1% higher than the control UASB (i.e. 1366.4 ± 71.0 mL-CH4 L(-1)-reactor d(-1)). The further characterizations verified that the input of external power source could stimulate the metabolic activity of microbes and reinforced the EPS secretion. The produced EPS interacted with Fe(2+/3+) liberated during anodic corrosion of iron electrode to create a gel-like three-dimensional [-Fe-EPS-]n matrix, which promoted cell-cell cohesion and maintained the structural integrity of granules. Further observations via SEM and FISH analysis demonstrated that the use of bioelectrochemical stimulation promoted the growth and proliferation of microorganisms, which diversified the degradation routes of methanol, convert the wasted CO2 into methane and accordingly increased the process stability and methane productivity.

    `May you live in interesting times' - old Chinese curse. First, many thanks to John Avison, the retiring Honorary Editor, for his hard work over the last five years, and the steady development in style and content under his stewardship. I can only hope to live up to the standards that he set. The next five years will take us into a new millenium, an event preceded - in England and Wales at least - by a period of stability, reflection and consolidation in education. Or so we are told - but whether such a self-denying ordinance will actually be maintained by the Government both before and after an election in 1997 remains to be seen. Nevertheless, we shall be thankful for any mercies, however small, that permit forward thinking rather than instant response. One of the things that readers of a journal called Physics Education should be thinking about is the continued decline in the numbers of students studying physics post-16. This is not a purely local phenomenon; most European countries are finding a similar decline. There are exceptions, of course: in Scotland numbers studying physics for Highers are increasing. Is such a decline a good thing or a bad thing? Only a minority of post-16 physics students go on to use the bulk of what they have learned in further studies or vocations. Does a knowledge and understanding of physics contribute to the mental well-being and cultural level - let alone material comfort - of any except those who use physics professionally? Is physics defensible as a contribution to the mental armoury of the educated citizen - compared with chemistry, biology - or Latin, say?

    The objectives of this study were to determine the cord blood thyroid-stimulating hormone (TSH) and free T(4) (FT(4) ) levels in Turkish neonates and to determine whether these variables reveal iodine deficiency. We collected 818 cords from healthy mothers at parturition and measured levels of FT(4) and TSH. We also measured cord blood FT(4) and TSH levels in different stages of gestation and gender. We grouped the neonates according to cord serum TSH levels, either being less (Group A) or greater (Group B) than 10 mIU/L. Group A included 589 neonates (300 girls [51%] and 289 boys [49%]) and Group B included 229 neonates (105 girls [45%] and 124 boys [55%]). The percentage of subjects with cord blood TSH < 10 mIU/L and >10 mIU/L was 72% and 28%, respectively. Although cord TSH levels in Group B were greater than those in Group A (P < 0.001), cord blood FT(4) levels in Group B were lower than those in Group A (P < 0.05). There was no difference between both sex in terms of birthweight and maternal age. TSH and FT(4) levels did not vary according to neonate sex during gestation, except for from week 37 to 41. TSH levels of male neonates at the 41st week of gestation were higher than those of female neonates (P < 0.05). There were no effects of birthweight on TSH and FT(4) levels if the neonate was lighter than 2500 g at birth. TSH levels of male neonates were higher than those of female neonates when their birthweights were <2500 g (P < 0.05). There was no significant difference in TSH levels according to birthweights in male neonates. Our data provide the normative data for cord blood TSH and FT(4) levels in Turkish neonates and show that iodine deficiency is a still a public health problem in Turkey. These measurements can be useful for detection and verification of hypothyroidism in a screening program for congenital hypothyroidism as well as evaluation of the success of the iodination program. © 2010 The Authors.

    Background: A randomized controlled trial was conducted in 2015 to evaluate a mobile continuing medical education (mCME) intervention that provided daily text messages to community-based physicians' assistants (CBPAs) in Thai Nguyen Province, Vietnam. Although the intervention failed to improve medical knowledge over a 6-month period, a companion qualitative study provided insights on the views and experiences of intervention participants. Methods: We conducted focus group discussions (FGDs) and in-depth interviews (IDIs) among participants randomized to receive text messages containing either simple medical facts or quiz questions. Trained interviewers collected data immediately following the conclusion of the trial in December 2015. Using semi-structured question guides, respondents were queried on their views of the intervention, positive and negative, and perceived impacts of the intervention. During analysis, after learning that the intervention had failed to increase knowledge among participants, we also examined reasons for lack of improvement in medical knowledge. All analyses were performed in NVivo using a thematic approach. Results: A total of 70 CBPAs engaged in one of 8 FGDs or an IDI. One-half were men; average age among all respondents was 40 years. Most (81%) practiced in rural settings and most (51%) focused on general medicine. The mean length of work experience was 3 years. All respondents made positive comments about the intervention; convenience, relevance, and quick feedback (quiz format) were praised. Downsides encompassed lack of depth of information, weak interaction, technology challenges, and challenging/irrelevant messages. Respondents described perceived impacts encompassing increased motivation, knowledge, collegial discussions, Internet use to search for more information, and clinical skills. Overall, they expressed a desire for the intervention to continue and recommended expansion to other medical professionals. Overreliance on the

    The dominant C96Y mutation of one of the two murine insulin genes, Ins2, causes diabetes mellitus in 'Akita' mice. Here we established pancreatic islet beta cell lines from heterozygous mice (Ins2+/Akita). Western blot analysis of endoplasmic reticulum (ER) molecular chaperones indicated that Grp78, Grp94 and Orp150 are significantly increased in Ins2+/Akita cells compared with wild-type (Ins2+/+) cells. Reporter gene assays using the human GRP78 promoter with or without the ER stress response element (ERSE) showed that Ins2+/Akita cells exhibit significantly stronger ERSE-dependent transcriptional activity than Ins2+/+ cells. Transient over-expression of the Ins2 C96Y mutant in wild-type beta cells induces a stronger ERSE-dependent stress response than does wild-type Ins2 over-expression. The ERSE-binding transcription factor ATF6 is strongly activated in Ins2+/Akita cells. The activity of a reporter containing the specific binding sequence of another ERSE-binding transcription factor, XBP1, is also enhanced in Ins2+/Akita cells. Levels of active forms of XBP1 mRNA and protein are both markedly elevated in Ins2+/Akita cells. These results indicate that this cell line is subject to continuous ER stress and that the Ins2 C96Y mutation induces the expression of ER chaperones through the activation of ATF6 and XBP1.

    2003-01-01

    Objective: Cool-water immersion (CWI) at 12.8°C (55°F), cathodal high-voltage pulsed current (CHVPC) at 120 pulses per second and 90% of visible motor threshold, or the combination of CWI and CHVPC, applied 30 minutes on, 30 minutes off for 4 hours, are known to curb edema formation after blunt trauma to the hind limbs of rats. Our purpose was to examine the effects of extending treatment times to 3 continuous hours after blunt trauma to the hind limbs of rats. Design and Setting: A randomized, parallel-groups design of 22 subjects was used. Volumes of traumatized limbs, randomly assigned to CWI (n = 7), CHVPC (n = 8), or CWI followed by CHVPC (n = 7) were compared with those of injured but untreated limbs with analysis of variance. Subjects: Twenty-two anesthetized Zucker lean rats (mass = 293 ± 27 g). Measurements: We measured limb volumes immediately before and after trauma and every 30 minutes over the 4-hour experiment. Results: Volumes of treated limbs of all 3 experimental groups were smaller than those of untreated limbs (P < .05). No treatment was more effective than another. Conclusions: Exposure to either 3 hours of CWI or CHVPC or to 1 hour of CWI followed by 2 hours of CHVPC effectively curbed edema after blunt injury. These results suggest that these common treatments are effective only during application and hint that application should be maintained throughout the period during which edema is forming.

    Background There are several methods of delivering cortical brain stimulation to modulate cortical excitability and interest in their application as an adjuvant strategy in aphasia rehabilitation after stroke is growing. Epidural cortical stimulation, although more invasive than other methods, permits high frequency stimulation of high spatial specificity to targeted neuronal populations. Aims First, we review evidence supporting the use of epidural cortical stimulation for upper limb recovery after focal cortical injury in both animal models and human stroke survivors. These data provide the empirical and theoretical platform underlying the use of epidural cortical stimulation in aphasia. Second, we summarize evidence for the application of epidural cortical stimulation in aphasia. We describe the procedures and primary outcomes of a safety and feasibility study (Cherney, Erickson & Small, 2010), and provide previously unpublished data regarding secondary behavioral outcomes from that study. Main Contribution In a controlled study comparing epidural cortical stimulation plus language treatment (CS/LT) to language treatment alone (LT), eight stroke survivors with nonfluent aphasia received intensive language therapy for 6 weeks. Four of these participants also underwent surgical implantation of an epidural stimulation device which was activated only during therapy sessions. Behavioral data were collected before treatment, immediately after treatment, and at 6 and 12 weeks following the end of treatment. The effect size for the primary outcome measure, the Western Aphasia Battery Aphasia Quotient, was benchmarked as moderate from baseline to immediately post-treatment, and large from baseline to the 12-week follow-up. Similarly, effect sizes obtained at the 12-week follow-up for the Boston Naming Test, the Communicative Effectiveness Index, and for correct information units on a picture description task were greater than those obtained immediately post treatment

    Continuous-time core-level photon-stimulated desorption (PSD) spectroscopy was used to study the soft x-ray-induced reactions of CF{sub 3}Br molecules adsorbed on Si(111)-7x7 near the Si(2p) edge (98-110 eV). The monochromatic synchrotron radiation was employed as a soft x-ray light source in the photon-induced reactions and also as a probe for investigating the produced fluorination states of the bonding surface Si atom in the positive-ion PSD spectroscopy. Several different surface coverages were investigated. The PSD spectra from the low-CF{sub 3}Br-covered surfaces show the production of surface SiF species, while those from the high-CF{sub 3}Br-covered surfaces depict the formation of surface SiF, SiF{sub 2}, and SiF{sub 3} species. The photolysis cross section of the submonolayer CF{sub 3}Br-covered surface is determined as {approx}4.3x10{sup -18} cm{sup 2}. A comparison with the results on CF{sub 3}Cl/Si(111)-7x7 surface is discussed.

    Whose interests should count and how should various interests be balanced at the pediatric patient's bedside? The interests of the child patient clearly count. Recently, however, many authors have argued that the family's interests also count. But how should we think about the interests of others? What does it mean to talk about "the family" in this context? Does it really just mean the interests of each individual family member? Or is the family itself a moral entity that has interests of its own independent of the interests of each of its members? Are such interests important only as they affect the patient's interest or also for their own sake? In this special supplement to Pediatrics, a group of pediatricians, philosophers, and lawyers grapple with these questions. They examine these issues from different angles and reach different conclusions. Jointly, they demonstrate the ethical importance and, above all, the ethical complexity of the family's role at the bedside.

    Obesity is now the third leading cause of preventable death in the US, accounting for 216,000 deaths annually and nearly 100 billion dollars in health care costs. Despite advancements in bariatric surgery, substantial weight regain and recurrence of the associated metabolic syndrome still occurs in almost 20-35% of patients over the long-term, necessitating the development of novel therapies. Our continually expanding knowledge of the neuroanatomic and neuropsychiatric underpinnings of obesity has led to increased interest in neuromodulation as a new treatment for obesity refractory to current medical, behavioral, and surgical therapies. Recent clinical trials of deep brain stimulation (DBS) in chronic cluster headache, Alzheimer’s disease, and depression and obsessive-compulsive disorder have demonstrated the safety and efficacy of targeting the hypothalamus and reward circuitry of the brain with electrical stimulation, and thus provide the basis for a neuromodulatory approach to treatment-refractory obesity. In this study, we review the literature implicating these targets for DBS in the neural circuitry of obesity. We will also briefly review ethical considerations for such an intervention, and discuss genetic secondary-obesity syndromes that may also benefit from DBS. In short, we hope to provide the scientific foundation to justify trials of DBS for the treatment of obesity targeting these specific regions of the brain. PMID:26180683

    Continuous dopamine (DA) stimulation is a therapeutic approach that applies to the treatment of motor fluctuations due to pulsatile DA stimulation in Parkinson's disease (PD), to cure the abuse of drugs, such as cocaine or amphetamine (which produce short-lasting peaks of extracellular DA), and as a safe therapeutic approach to avoid hedonistic homeostatic dysregulation (which sometime develops as an abuse pattern in PD patients receiving a pulsatile DA replacement therapy). However, systemic continuous delivery of DA agonists leads to a variety of side effects. In search for an alterative approach, in the present study we evaluated the possibility of delivering intracerebroventricularly (i.c.v.), a DA agonist: lisuride that was already shown to be effective when administered continuously subcutaneously (s.c.). In particular, we were interested in examining whether lisuride infused within the lateral ventricle was still able to stimulate DA receptor by inducing contralateral turning behavior in hemiparkinsonian rats. We found that lisuride, when infused in the lateral ventricle was effective in reducing the threshold for stimulating DA receptors. These results offer a more reliable and safe therapeutic approach to deliver continuous DA selectively in the brain.

    Psychiatry as a field was transformed by the discovery and introduction of electroconvulsive therapy (ECT) as a treatment in the early part of this century. ECT demonstrated that depression was a disease of the brain and that it could be treated with a direct brain intervention. Psychiatry's evolution continued in 1958 with the discovery of the antidepressant activity of the monoamine oxidase inhibitors. Interestingly, although the area of neuropsychopharmacology has continued to advance, the realm of physical somatic interventions in psychiatry has lagged behind. With perhaps the exception of light therapy, there were no advances in somatic interventions in psychiatry. However, in 1985, Barker et al. developed a brief high intensity electromagnet capable of depolarizing cortical neurons, called transcranial magnetic stimulation (TMS). There has been much interest in the past 10 years in whether TMS might have antidepressant actions, similar to ECT but without causing a seizure and with no apparent cognitive side effects. This review examines the basic principles underlying TMS, and describes how TMS differs from electrical stimulation and the other uses of magnets.

  6. Multi-Electrode Array for Transcutaneous Lumbar Posterior Root Stimulation.

    Interest in transcutaneous electrical stimulation of the lumbosacral spinal cord is increasing in human electrophysiological and clinical studies. The stimulation effects on lower limb muscles depend on the depolarization of segmentally organized posterior root afferents and, thus, the rostro-caudal stimulation site. In previous studies, selective stimulation was achieved by varying the positions of single self-adhesive electrodes over the thoracolumbar spine. Here, we developed a multi-electrode surface array consisting of 3 × 8 electrode pads and tested its stimulation-site specificity. The array was placed longitudinally over the spine covering the T10-L2 vertebrae. Two different hydrogel layer configurations were utilized: a single layer adhered to all electrode pads of the array and a configuration comprised of eight separate strips attached to the three transverse electrode pads of each level. Voltage measurements demonstrated that an effectively focused field distribution along the longitudinal extent of the array was not accomplished when using the single continuous hydrogel layer, and segmental selective stimulation of the posterior root afferents was not possible. The separate strips produced a focused electric field distribution at the rostro-caudal level of the electrode pads selected for stimulation. This configuration allowed for the preferential elicitation of posterior root-muscle reflexes in either the L2-L4 innervated quadriceps or the L5-S2 innervated triceps surae muscle groups. Such multi-electrode array for transcutaneous spinal cord stimulation shall allow for improved control of stimulation conditions in electrophysiological studies and time-dependent and site-specific stimulation patterns for neuromodulation applications.

  7. ICPD: in whose interest?

    PubMed

    Shiva, M

    1994-06-01

    The International Conference on Population and Development (ICPD) is set for September 1994. Arms control and control of military interests are as crucial as population control. The expenditure on the military and arms should go to social measures and true socioeconomic development. Women are leading the movement against war and towards peace. Women make up 70% of current refugees of ethnic conflicts. The conquest of free trade with little or no restriction and globalization trends forces developing countries to accept nonessential luxury items which tend to be irrational, hazardous consumer articles and technologies from industrialized countries. The privileged elite in developing countries and the industrialized countries overconsume, while the basic needs of the poor majority are not being met. The rich view the poor as a global threat and a threat for environmental degradation. They believe that free trade will solve all problems, yet it only marginalizes the poor and the vulnerable. The pattern of overconsumption is the threat. The poor are characterized as demons responsible for the population explosion. Women are angry that population control policies are attempts to control women's fertility. Specifically, most contraceptive technologies and most family planning programs target women. Male responsibility is ignored. Religious fundamentalists tell women not to become pregnant, not to use contraception, and not to seek abortion, yet they allow male sex behavior, e.g., sexual violence. This attitude leaves women vulnerable to unwanted pregnancies, sexually transmitted diseases, and AIDS. Developing countries should be concerned about chapter III on Population, Environment, and Development in the ICPD text. Most countries, including India, have formed a consensus on this chapter. The Vatican and some Latin American countries have objections, however. The meeting in Cairo will likely continue to promote the view that the fertility of women in developing

    The comparison between the memories productions of residents in a nursing home through two reminiscence activities, one including olfaction and not the other one, can highlight an increasing occurrence of recent memories in the case of olfactory activity. A longer talk time is also observed and a better self-esteem can be assessed. This suggests the possibility of a specific relational and psychotherapeutic work. Copyright © 2016 Elsevier Masson SAS.

  12. Stimulating parameters and de-synchronization in vagus nerve stimulation therapy for epilepsy

    NASA Astrophysics Data System (ADS)

    2008-02-01

    The influence of the stimulation parameters on the de-synchronization of small world Hindmarsh-Rose (H-R) neural network is numerically investigated in the vagus nerve stimulation therapy for epilepsy. The simulation shows that synchronization evolves into de-synchronization when a part of neurons (about 10 percent) is stimulated with a pulse current signal. The network de-synchronization appears to be sensitive to the stimulation parameters. For the case of the same stimulation intensity, those weakly coupled networks reach de-synchronization more easily than strongly coupled networks. There exist an optimal stimulation interval and period of continuous stimulation time when other stimulation parameters remain invariable.

    Genetics is becoming increasingly integrated into peoples' lives. Different measures have been taken to try and better genetics education. This thesis examined undergraduate students at the University of North Texas not majoring in the life sciences interest in genetic concepts through the means of a Likert style survey. ANOVA analysis showed there was variation amongst the interest level in different genetic concepts. In addition age and lecture were also analyzed as contributing factors to students' interest. Both age and lecture were evaluated to see if they contributed to the interest of students in genetic concepts and neither showed statistical significance. The Genetic Interest Assessment (GIA) serves to help mediate the gap between genetic curriculum and students' interest.

  15. Long-acting stimulants for treatment of attention-deficit/hyperactivity disorder: a focus on extended-release formulations and the prodrug lisdexamfetamine dimesylate to address continuing clinical challenges.

    2013-09-01

    Individuals with attention-deficit/hyperactivity disorder (ADHD) show pervasive impairments across family, peer, and school or work functioning that may extend throughout the day. Psychostimulants are highly effective medications for the treatment of ADHD, and the development of long-acting stimulant formulations has greatly expanded the treatment options for individuals with ADHD. Strategies for the formulation of long-acting stimulants include the combination of immediate-release and delayed-release beads, and an osmotic-release oral system. A recent development is the availability of the first prodrug stimulant, lisdexamfetamine dimesylate (LDX). LDX itself is inactive but is cleaved enzymatically, primarily in the bloodstream, to release d-amphetamine (d-AMP). Several clinical trials have demonstrated that long-acting stimulants are effective in reducing ADHD symptoms compared with placebo. Analog classroom and simulated adult workplace environment studies have shown that long-acting stimulants produce symptom reduction for at least 12 h. Long-acting stimulants exhibit similar tolerability and safety profiles to short-acting equivalents. While variations in gastric pH and motility can alter the availability and absorption of stimulants released from long-acting formulations, the systemic exposure to d-AMP following LDX administration is unlikely to be affected by gastrointestinal conditions. Long-acting formulations may also improve adherence and lower abuse potential compared with their short-acting counterparts. The development of long-acting stimulants provides physicians with an increased range of medication options to help tailor treatment for individuals with ADHD.

  16. Best interests and pragmatism.

    McGuinness, Sheelagh

    2008-09-01

    In this article I will show that 'best interests' is a concept that fits nicely with many of the features of pragmatism--Holm and Edgar's rejection of the principle in favour of pragmatism it will be suggested is misplaced. 'Best interests' as a principle may be considered an embodiment of the ideals of pragmatic adjudication. The paper starts by briefly introducing the concept of 'best interests' and theories of judicial and legal 'pragmatism'. This article will examine the role of the rational decision-maker in medical law and argue that this role is limited. The paper concludes by suggesting how we view the relationship between 'best interests' and 'pragmatism'.

    1978-02-01

    51 (15%) were enacted into law. More abortion laws were enacted than in any year since 1973 (when the Supreme Court declared women have a right to first trimester abortions); none of them had the effect of increasing access to abortion, and 5 laws restricted its availability to minors. 2 states (California and Michigan) passed bills broadening the scope of sex education. Although 2 states (Missouri and North Carolina) passed laws permitting minors to consent to pregnancy-related medical care, both excluded abortion, 1 (North Carolina) excluded sterilization, and neither gave minors authority to consent to contraceptive services. 3 laws were enacted relating to sterilization: 2 in North Carolina (repeal of requirement for a 2nd physician to be consulted before performing a sterilization, and abolishment of the eugenics commission which oversaw the sterilization of certain mentally ill or retarded persons) and 1 in Massachusetts (requiring informed consent for sterilization). 4 of the 9 new family planning laws related to financing state family planning programs, 3 of which are appropriations bills, and the other 5 laws related to sale of prophylactics and the distribution of family planning information in maternity hospitals and prisons. New insurance laws ensure coverage of family planning services or equal treatment of pregnancy-related disabilities. 10 resolutions were adopted in 6 states (Arkansas, Massachusetts, New Jersey, Rhode Island, South Dakota, and Utah) asking Congress to call a constitutional convention for proposing an amendment on abortion, i.e., prohibiting abortion.

    Godfrey-Smith, Peter; Martínez, Manolo

    2013-01-01

    Explaining the maintenance of communicative behavior in the face of incentives to deceive, conceal information, or exaggerate is an important problem in behavioral biology. When the interests of agents diverge, some form of signal cost is often seen as essential to maintaining honesty. Here, novel computational methods are used to investigate the role of common interest between the sender and receiver of messages in maintaining cost-free informative signaling in a signaling game. Two measures of common interest are defined. These quantify the divergence between sender and receiver in their preference orderings over acts the receiver might perform in each state of the world. Sampling from a large space of signaling games finds that informative signaling is possible at equilibrium with zero common interest in both senses. Games of this kind are rare, however, and the proportion of games that include at least one equilibrium in which informative signals are used increases monotonically with common interest. Common interest as a predictor of informative signaling also interacts with the extent to which agents' preferences vary with the state of the world. Our findings provide a quantitative description of the relation between common interest and informative signaling, employing exact measures of common interest, information use, and contingency of payoff under environmental variation that may be applied to a wide range of models and empirical systems.

    Some argue that the goal of education is to influence out-of-school learning activity, yet little research exists on how teachers can help students develop an interest in a topic and continue to pursue that interest outside of school. The current study tested classroom context variables from self-determination theory (teachers' autonomy support)…

    Deep brain stimulation (DBS) has provided remarkable therapeutic benefits for people with a variety of neurological disorders. Despite the uncertainty of the precise mechanisms underlying its efficacy, DBS is clinically effective in improving motor function of essential tremor, Parkinson's disease and primary dystonia and in relieving obsessive-compulsive disorder. Recently, this surgical technique has continued to expand to other numerous neurological diseases with encouraging results. This review highlighted the current and potential future clinical applications of DBS. PMID:25187779

    The aim of the present mixed-method study was to investigate task-based situational interest of sixth grade students (n = 46), between 12 and 14 years old, during an eight-week engineering design programme in a Science & Technology-class. Students' interests were investigated by means of a descriptive interpretative analysis of qualitative data from classroom observations and informal interviews. The analysis was complemented by a self-report survey to validate findings and determine prevalence. The analysis revealed four main sources of interest: designing inventions, trial-and-error experimentation, achieved functionality of invention, and collaboration. These sources differ in terms of stimuli factors, such as novelty, autonomy (choice), social involvement, self-generation of interest, and task goal orientation. The study shows that design tasks stimulated interest, but only to the extent that students were able to self-regulate their learning strategies.

  15. Kentucky rural stimulant use: a comparison of methamphetamine and other stimulant users.

    Population based surveys suggest that methamphetamine use is increasing. However, little is known about stimulant use in rural areas. Given the lack of data regarding rural stimulant use, particularly methamphetamine use, and the continuing problems associated with stimulant drug use, the purpose of this study was to examine rural stimulant use in Kentucky. Of 225 rural stimulant-using participants surveyed, 76% (n = 170) reported lifetime use of methamphetamine. Rural methamphetamine users differed from other rural stimulant users on demographic characteristics, health, and drug use histories. These results suggest that differences exist between rural stimulant users and that clinicians may need to consider these differences when planning treatment and rehabilitation strategies.

  16. Copeptin under glucagon stimulation.

    Stimulation of growth hormone (GH) and adrenocorticotropic hormone (ACTH) secretion by glucagon is a standard procedure to assess pituitary dysfunction but the pathomechanism of glucagon action remains unclear. As arginine vasopressin (AVP) may act on the release of both, GH and ACTH, we tested here the role of AVP in GST by measuring a stable precursor fragment, copeptin, which is stoichiometrically secreted with AVP in a 1:1 ratio. ACTH, cortisol, GH, and copeptin were measured at 0, 60, 90, 120, 150, and 180 min during GST in 79 subjects: healthy controls (Group 1, n = 32), subjects with pituitary disease, but with adequate cortisol and GH responses during GST (Group 2, n = 29), and those with overt hypopituitarism (Group 3, n = 18). Copeptin concentrations significantly increased over baseline 150 and 180 min following glucagon stimulation in controls and patients with intact pituitary function but not in hypopituitarism. Copeptin concentrations were stimulated over time and the maximal increment correlated with ACTH, while correlations between copeptin and GH were weaker. Interestingly, copeptin as well as GH secretion was significantly attenuated when comparing subjects within the highest to those in the lowest BMI quartile (p < 0.05). Copeptin is significantly released following glucagon stimulation. As this release is BMI-dependent, the time-dependent relation between copeptin and GH may be obscured, whereas the close relation to ACTH suggests that AVP/copeptin release might be linked to the activation of the adrenal axis.

  3. New stimulation regimens: endogenous and exogenous progesterone use to block the LH surge during ovarian stimulation for IVF.

    PubMed

    Massin, Nathalie

    2017-03-01

    The advent of embryo and oocyte vitrification today gives reproductive specialists an opportunity to consider new strategies for improving the practice and results of IVF attempts. As the freezing of entire cohorts does not compromise, and may even improve, the results of IVF attempts, it is possible to break away from the standard sequence of stimulation-retrieval-transfer. The constraints associated with ovarian stimulation in relation to the potential harmful effects of the hormonal environment on endometrial receptivity can be avoided. This review will look at the new stimulation protocols where progesterone is used to block the LH surge. Thanks to 'freeze all' strategies, the increase in progesterone could actually be no longer a cause for concern. There are two ways of using progesterone, whether it be endogenous, as in luteal phase stimulation, or exogenous, as in the use of progesterone in the follicular phase i.e. progestin primed ovarian stimulation. A literature search was carried out (until September 2016) on MEDLINE. The following text words were utilized to generate the list of citations: progestin primed ovarian stimulation, luteal phase stimulation, luteal stimulation, duostim, double stimulation, random start. Articles and their references were then examined in order to identify other potential studies. All of the articles are reported in this review. The use of progesterone during ovarian stimulation is effective in blocking the LH surge, whether endogenous or exogenous, and it does not affect the number of oocytes collected or the quality of the embryos obtained. Its main constraint is that it requires total freezing and delayed transfer. A variety of stimulation protocols can be derived from these two methods, and their implications are discussed, from fertility preservation to ovarian response profiles to organization for the patients and clincs. These new regimens enable more flexibility and are of emerging interest in daily practice. However

  17. Using Situational Interest to Enhance Individual Interest and Science-Related Behaviours

    NASA Astrophysics Data System (ADS)

    Palmer, David; Dixon, Jeanette; Archer, Jennifer

    2016-08-01

    Situational interest is a relatively transient reaction to highly stimulating factors in the immediate environment, whereas individual interest is a relatively long-term preference for a particular subject or activity. It has been proposed that regular experiences of situational interest in a subject may eventually lead to the development of individual interest in that subject. Importantly, this should also result in an increase in behaviours related to that domain. For example, a student who develops an individual interest in science would be expected to spend more time on science-related activities such as reading about science, talking with other people about science, or watching science shows on TV. However, the extent to which this does happen has not yet been established. The purposes of this study were to find out whether regular experiences of situational interest in science classes can enhance individual interest in science and whether there is an associated increase in science-related activities. The participants were primary teacher education students who were enrolled in a semester-length science course. Data were collected using a survey, an interest inventory, open-ended questionnaires and interviews. It was found that regular experiences of situational interest during the course were associated with positive changes in individual interest in science and increased participation in science-related activities. These changes remained relatively stable over a delay period of 10 months after the end of the course.

    Deep brain stimulation has significantly improved the motor symptoms in patients with Parkinson's disease (PD) and other movement disorders. The mechanisms responsible for these improvements continue to be explored. Inhibition at the site of stimulation has been the prevailing explanation for the symptom improvement observed with deep brain stimulation. Research using microelectrode recording during deep brain stimulation in the MPTP monkey model of PD has helped clarify how electrical stimulation of structures within the basal ganglia-thalamocortical circuit improves motor symptoms, and suggests that activation of output and the resultant change in pattern of neuronal activity that permeates throughout the basal ganglia motor circuit is the mechanism responsible for symptom improvement.

  20. Upgraded Coal Interest Group

    The Upgraded Coal Interest Group (UCIG) is an EPRI 'users group' that focuses on clean, low-cost options for coal-based power generation. The UCIG covers topics that involve (1) pre-combustion processes, (2) co-firing systems and fuels, and (3) reburn using coal-derived or biomass-derived fuels. The UCIG mission is to preserve and expand the economic use of coal for energy. By reducing the fuel costs and environmental impacts of coal-fired power generation, existing units become more cost effective and thus new units utilizing advanced combustion technologies are more likely to be coal-fired.

  1. Electrical stimulation in exercise training

    Electrical stimulation has a long history of use in medicine dating back to 46 A.D. when the Roman physician Largus found the electrical discharge of torpedo fishes useful in the treatment of pain produced by headache and gout. A rival Greek physician, Dioscorides, discounted the value of the torpedo fish for headache relief but did recommend its use in the treatment of hemorrhoids. In 1745, the Leyden jar and various sized electrostatic generators were used to treat angina pectoris, epilepsy, hemiplegia, kidney stones, and sciatica. Benjamin Franklin used an electrical device to treat successfully a young woman suffering from convulsive fits. In the late 1800's battery powered hydroelectric baths were used to treat chronic inflammation of the uterus while electrified athletic supporters were advertised for the treatment of male problems. Fortunately, such an amusing early history of the simple beginnings of electrical stimulation did not prevent eventual development of a variety of useful therapeutic and rehabilitative applications of electrical stimulation. Over the centuries electrical stimulation has survived as a modality in the treatment of various medical disorders with its primary application being in the rehabilitation area. Recently, a surge of new interest in electrical stimulation has been kindled by the work of a Russian sport scientist who reported remarkable muscle strength and endurance improvements in elite athletes. Yakov Kots reported his research on electric stimulation and strength improvements in 1977 at a Canadian-Soviet Exchange Symposium held at Concordia University in Montreal. Since then an explosion of new studies has been seen in both sport science and in medicine. Based upon the reported works of Kots and the present surge of new investigations, one could be misled as to the origin of electrical stimulation as a technique to increase muscle strength. As a matter of fact, electric stimulation has been used as a technique to improve

  2. [Caloric stimulation in infants].

    Caloric stimulation is one of few clinically proven tests assessing the function of each vestibule separately in neonates. Its results represent the continuity of vestibulo-ocular reflex, beginning in the lateral vestibular canal. Vestibular disorders are diagnosed in 20 to even 70% neonates with sensorineural hearing loss with the prevalence of individuals with profound and acquired deafness. 58 high risk of hearing defect infants were included in the study. Their age ranged from 3 to 6 months. A group of 27 healthy controls with negative history concerning sensorineural hearing loss risk factors was also examined. Caloric stimulation was performed according to Veits. External ear canal was irrigated with 20 ml of water at the temperature of 20 degrees C and eye movements were watched indirectly. In about 34% infants the nystagmic reaction to cold water was weaker than in normal controls. The reaction was most frequently impaired in infants with perinatal pathology, multiple congenital defects and aminoglycoside administration. Caloric stimulation in infants should be performed with cold water and the syringe used in the test should be fitted with a soft hose enabling irrigation of the interior part of the external ear canal.

  3. Only conflicts of interest?

    PubMed

    Obrist, Reto

    2015-01-01

    The current situation of the biomedical sciences is critically discussed. It can be summarized as follows: 1. We have to acknowledge the presence of a serious credibility problem, which might undermine the foundations of medical science. ("Sliding on a slippery slope") 2. Multiple forces going beyond simple conflicts of interest push medical science further down the slippery slope. ("Who is pushing?") 3. The public awareness of something seriously wrong with medical science is mounting on all levels of our multimedia society. ("Looking into the media mirror") 4. Technical corrective measures may be easily implemented, however, to change an expanding and "successful" science culture actually destroying it's own foundations will need a sustained effort by the medical and scientific community on all levels. ("Look away--or act?").

  12. Column continuous transition functions

    NASA Astrophysics Data System (ADS)

    Li, Yangrong

    2007-04-01

    A column continuous transition function is by definition a standard transition function P(t) whose every column is continuous for t[greater-or-equal, slanted]0 in the norm topology of bounded sequence space l[infinity]. We will prove that it has a stable q-matrix and that there exists a one-to-one relationship between column continuous transition functions and increasing integrated semigroups on l[infinity]. Using the theory of integrated semigroups, we give some necessary and sufficient conditions under which the minimal q-function is column continuous, in terms of its generator (of the Markov semigroup) as well as its q-matrix. Furthermore, we will construct all column continuous Q-functions for a conservative, single-exit and column bounded q-matrix Q. As applications, we find that many interesting continuous-time Markov chains (CTMCs), say Feller-Reuter-Riley processes, monotone processes, birth-death processes and branching processes, etc., have column continuity.

  13. New Type Continuities via Abel Convergence

    PubMed Central

    Albayrak, Mehmet

    2014-01-01

    We investigate the concept of Abel continuity. A function f defined on a subset of ℝ, the set of real numbers, is Abel continuous if it preserves Abel convergent sequences. Some other types of continuities are also studied and interesting result is obtained. It turned out that uniform limit of a sequence of Abel continuous functions is Abel continuous and the set of Abel continuous functions is a closed subset of continuous functions. PMID:24883393

  11. WHAT ARE 'BEST INTERESTS'? A CRITICAL EVALUATION OF 'BEST INTERESTS' DECISION-MAKING IN CLINICAL PRACTICE.

    PubMed

    Taylor, Helen J

    2016-01-01

    Obtaining the patient's consent is usually a prerequisite of any clinical intervention. However, some cognitively impaired patients may not be able to give valid consent. Following years of consultation and legislative review, the Mental Capacity Act 2005 (MCA) provides a statutory framework of 'best interests' decision-making on behalf of incapacitated individuals. However, confusion over the meaning and application of the 'best interests' standard persists. This paper explores the variation in judicial interpretation of the standard and the complexities of best interests decision-making in clinical practice. Prevailing confusion and risk-aversive practices mean that the rights and interests of cognitively impaired individuals continue to be compromised, with evidence to suggest that 'best interests' may be conflated with the clinician's evaluation of 'best medical interests'.

    NASA Astrophysics Data System (ADS)

    Dai, Zhibin; Szkody, Paula; Garnavich, Peter M.; Kennedy, Mark

    2015-01-01

    Cataclysmic Variables (CVs) comprise one category of active mass transfer binaries containing a white dwarf accreting from an orbiting late main-sequence companion. Undoubtedly, non-magnetic CVs, intermediate polars and polars constitute a powerful probe of the structure of accretion onto white dwarfs and the theories of angular momentum loss, which elucidate the long-term evolution leading to the formation of these short period compact binaries. Combining photometric and spectroscopic data from space and ground telescopes can lead to novel discoveries. The SDSS survey provided a large dataset of spectra of different types of CVs. Followup photometry and spectroscopy is still underway to determine the unique properties of the objects identified as CVs. The Kepler program provided the first look at the variability of CVs over a continuous timescale of months. The extension of the program to the K2 fields allows further sets of CVs to be explored. We present some interesting results for several new CVs found in the SDSS and Kepler surveys which include their behavior during quiescence and outburst. These observations further demonstrate the complexities of CVs. This research was partially funded by CAS visiting scholar grant, NSF grant AST-1008734 and NASA grant HST-GO12870.

    2016-01-01

    Cosmic Dawn was identified as one of the three science objectives for this decade in the _New Worlds, New Horizons_ Decadal report, and it will likely continue to be a research focus well into the next decade. Cosmic Dawn refers to the interval during which the Universe transitioned from a nearly completely neutral state back to a nearly fully ionized state and includes the time during which the first stars formed and the first galaxies assembled.The Cosmic Dawn Science Interest Group (SIG) was formed recently under the auspices of the Cosmic Origins Program Analysis Group (COPAG). The Cosmic Dawn SIG focusses on the science cases, observations, and technology development needed to address the "great mystery" of Cosmic Origins. The reach of this SIG is broad, involving the nature of the first stars and the detectability of gamma-ray bursts at high redshifts, the extent to which the first galaxies and first supermassive black holes grew together, and the technology required to pursue these questions.For further information, consult the Cosmic Dawn SIG Web site http://cd-sig.jpl.nasa.gov/ and join the mailing list (by contacting the author).Part of this research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.

    2011-08-12

    Stimulating a system with time dependent sources can enhance instabilities, thus increasing the critical temperature at which the system transitions to interesting low-temperature phases such as superconductivity or superfluidity. After reviewing this phenomenon in non-equilibrium BCS theory (and its marginal fermi liquid generalization) we analyze the effect in holographic superconductors. We exhibit a simple regime in which the transition temperature increases parametrically as we increase the frequency of the time-dependent source.

  7. Detection of erythropoiesis-stimulating agents in human anti-doping control: past, present and future.

    PubMed

    Leuenberger, Nicolas; Reichel, Christian; Lasne, Françoise

    2012-07-01

    Stimulation of erythropoiesis is one of the most efficient ways of doping. This type of doping is advantageous for aerobic physical exercise and of particular interest to endurance athletes. Erythropoiesis, which takes place in bone marrow, is under the control of EPO, a hormone secreted primarily by the kidneys when the arterial oxygen tension decreases. In certain pathological disorders, such as chronic renal failure, the production of EPO is insufficient and results in anemia. The pharmaceutical industry has, thus, been very interested in developing drugs that stimulate erythropoiesis. With this aim, various strategies have been, and continue to be, envisaged, giving rise to an expanding range of drugs that are good candidates for doping. Anti-doping control has had to deal with this situation by developing appropriate methods for their detection. This article presents an overview of both the drugs and the corresponding methods of detection, and thus follows a roughly chronological order.

  8. What is interesting? Exploring the appraisal structure of interest.

    PubMed

    Silvia, Paul J

    2005-03-01

    Relative to other emotions, interest is poorly understood. On the basis of theories of appraisal process and structure, it was predicted that interest consists of appraisals of novelty (factors related to unfamiliarity and complexity) and appraisals of coping potential (the ability to understand the new, complex thing). Four experiments, using in vivo rather than retrospective methods, supported this appraisal structure. The findings were general across measured and manipulated appraisals, interesting stimuli (random polygons, visual art, poetry), and measures of interest (self-reports, forced-choice, behavioral measures). Furthermore, the appraisal structure was specific to interest (it did not predict enjoyment, a related positive emotion), and appraisals predicted interest beyond relevant traits (curiosity, openness). The appraisal perspective offers a powerful way of construing the causes of interest.

  9. Shareholder interests and utility competition

    SciTech Connect

    Studness, C.M.

    1995-03-15

    The process of determining how to implement utility competition is often cast as a struggle between two opposing camps: shareholders and ratepayers. There are, of course, two other major players, management and regulators. The bipolar view tacitly assumes that shareholder and management interests coincide and that regulators have customer interests at heart. Neither assumption is valid. Shareholder interests deviate from management interests in important ways, just as the interests of the entrenched regulatory bureaucracy diverge from the public interest. Therefore, shareholder and management interests must be considered separately. In the past, managements have often pursued their own interests, with devastating financial impact on shareholders. Competition offers shareholders an opportunity to increase their leverage over managements, thereby increasing their returns as well.

    2012-01-01

    Brain stimulation techniques have evolved in the last few decades with more novel methods capable of painless, noninvasive brain stimulation. While the number of clinical trials employing noninvasive brain stimulation continues to increase in a variety of medication-resistant neurological and psychiatric diseases, studies evaluating their diagnostic and therapeutic potential in traumatic brain injury (TBI) are largely lacking. This review introduces different techniques of noninvasive brain stimulation, which may find potential use in TBI. We cover transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), low-level laser therapy (LLLT) and transcranial doppler sonography (TCD) techniques. We provide a brief overview of studies to date, discuss possible mechanisms of action, and raise a number of considerations when thinking about translating these methods to clinical use.

    ABSTRACT Objective The study was designed to determine the effect of low frequency (2.5Hz) intraurethral electrical stimulation on bladder capacity and maximum voiding pressures. Materials and Methods The experiments were conducted in 15 virgin female Sprague-Dawley rats (220–250g). The animals were anesthetized by intraperitoneal injection of urethane (1.5g/kg). Animal care and experimental procedures were reviewed and approved by the Institutional Animal Care and Use Committee of Antwerp University (code: 2013-50). Unipolar square pulses of 0.06mA were used to stimulate urethra at frequency of 2.5Hz (0.2ms pulse width) in order to evaluate the ability of intraurethral stimulation to inhibit bladder contractions. Continuous stimulation and intermittent stimulation with 5sec ‘‘on’’ and 5sec ‘‘off’’ duty cycle were applied during repeated saline cystometrograms (CMGs). Maximum voiding pressures (MVP) and bladder capacity were investigated to determine the inhibitory effect on bladder contraction induced by intraurethral stimulation. Results The continuous stimulation and intermittent stimulation significantly (p<0.05) decreased MVP and increased bladder capacity. There was no significant difference in MVP and bladder capacity between continuous and intermittent stimulation group. Conclusions The present results suggest that 2.5Hz continuous and intermittent intraurethral stimulation can inhibit micturition reflex, decrease MVP and increase bladder capacity. There was no significant difference in MVP and bladder capacity between continuous and intermittent stimulation group. PMID:27286128

    To describe the aspects of continuing education in pharmacological therapeutics considered as most relevant by the primary health care physicians. Observational study.Setting. Physicians filled-up the questionnaires during 45 minutes at their primary health care centres. Primary health care physicians involved in the Fundation Institut Català de Farmacologia continuing education activities since 1997 were selected. A specific questionnaire was designed to collect the physicians' opinion on different topics regarding continuing education in pharmacological therapeutics. 180 physicians from 21 primary health care centres answered the questionnaire. 68% of the responding physicians considered that continuing education has to be useful to improve routine clinical practice. Regular seminars and methods stimulating active participation administered by primary health care professionels are preferred. Continuing education in pharmacological therapeutics should be focused to health problems rather than being drug-oriented. They referred being more interested in drug selection issues and in the role of new drug in comparison with the existing alternatives rather than in regulation and drug consumption issues. 66,3% of the responding physicians considered that continuing education in pharmacological therapeutics should be compulsory. Public health authorities and primary health care physicians should share the responsibility in setting-up continuing education in pharmacological therapeutics programs, according to the opinion of almost 70% of the physicians. Primary health care physicians are interested in continuing education in pharmacological therapeutics as far as it is practical and useful to solve problems of their routine clinical practice.

  5. Continuous quantum hypothesis testing.

    PubMed

    Tsang, Mankei

    2012-04-27

    I propose a general quantum hypothesis testing theory that enables one to test hypotheses about any aspect of a physical system, including its dynamics, based on a series of observations. For example, the hypotheses can be about the presence of a weak classical signal continuously coupled to a quantum sensor, or about competing quantum or classical models of the dynamics of a system. This generalization makes the theory useful for quantum detection and experimental tests of quantum mechanics in general. In the case of continuous measurements, the theory is significantly simplified to produce compact formulas for the likelihood ratio, the central quantity in statistical hypothesis testing. The likelihood ratio can then be computed efficiently in many cases of interest. Two potential applications of the theory, namely, quantum detection of a classical stochastic waveform and test of harmonic-oscillator energy quantization, are discussed.

    2015-08-01

    Electrical stimulation (ES) of the upper airway (UAW) dilator muscles for patients with obstructive sleep apnoea (OSA) has been used for several decades, but in recent years research in this field has experienced a renaissance; the results of several studies have triggered a steady rise in the interest in this topic. Prospective trials, although still lacking a sham-controlled and randomised approach, have revealed the potential of ES. Hypoglossal nerve stimulation (HNS) leads to a significant reduction in the apnoea-hypopnoea index and the oxygen desaturation index (ODI). There are similar results published from feasibility studies for transcutaneous ES. A limitation of HNS remains the invasive procedure, the costs involved and severe adverse events, while for the non-invasive approach complications are rare and limited. The limiting step for transcutaneous ES is to deliver a sufficient current without causing arousal from sleep. Despite the progress up to date, numerous variables including optimal stimulation settings, different devices and procedures remain to be further defined for the invasive and the non-invasive method. Further studies are required to identify which patients respond to this treatment. ES of the UAW dilator muscles in OSA has the potential to develop into a clinical alternative to continuous positive airway pressure (CPAP) therapy. It could benefit selected patients who fail standard therapy due to poor long-term compliance. It is likely that international societies will need to review and update their existing guidance on the use of ES in OSA.

    2012-06-26

    Electrical stimulation is currently used to treat a wide range of cardiovascular, sensory and neurological diseases. Despite its success, there are significant limitations to its application, including incompatibility with magnetic resonance imaging, limited control of electric fields and decreased performance associated with tissue inflammation. Magnetic stimulation overcomes these limitations but existing devices (that is, transcranial magnetic stimulation) are large, reducing their translation to chronic applications. In addition, existing devices are not effective for deeper, sub-cortical targets. Here we demonstrate that sub-millimeter coils can activate neuronal tissue. Interestingly, the results of both modelling and physiological experiments suggest that different spatial orientations of the coils relative to the neuronal tissue can be used to generate specific neural responses. These results raise the possibility that micro-magnetic stimulation coils, small enough to be implanted within the brain parenchyma, may prove to be an effective alternative to existing stimulation devices.

  15. Deep brain stimulation for psychiatric disorders: where we are now.

    PubMed

    Cleary, Daniel R; Ozpinar, Alp; Raslan, Ahmed M; Ko, Andrew L

    2015-06-01

    Fossil records showing trephination in the Stone Age provide evidence that humans have sought to influence the mind through physical means since before the historical record. Attempts to treat psychiatric disease via neurosurgical means in the 20th century provided some intriguing initial results. However, the indiscriminate application of these treatments, lack of rigorous evaluation of the results, and the side effects of ablative, irreversible procedures resulted in a backlash against brain surgery for psychiatric disorders that continues to this day. With the advent of psychotropic medications, interest in invasive procedures for organic brain disease waned. Diagnosis and classification of psychiatric diseases has improved, due to a better understanding of psychiatric patho-physiology and the development of disease and treatment biomarkers. Meanwhile, a significant percentage of patients remain refractory to multiple modes of treatment, and psychiatric disease remains the number one cause of disability in the world. These data, along with the safe and efficacious application of deep brain stimulation (DBS) for movement disorders, in principle a reversible process, is rekindling interest in the surgical treatment of psychiatric disorders with stimulation of deep brain sites involved in emotional and behavioral circuitry. This review presents a brief history of psychosurgery and summarizes the development of DBS for psychiatric disease, reviewing the available evidence for the current application of DBS for disorders of the mind.

    Vagus nerve stimulation has recently been reported to improve symptoms of migraine. Cortical spreading depression is the electrophysiological event underlying migraine aura and is a trigger for headache. We tested whether vagus nerve stimulation inhibits cortical spreading depression to explain its antimigraine effect. Unilateral vagus nerve stimulation was delivered either noninvasively through the skin or directly by electrodes placed around the nerve. Systemic physiology was monitored throughout the study. Both noninvasive transcutaneous and invasive direct vagus nerve stimulations significantly suppressed spreading depression susceptibility in the occipital cortex in rats. The electrical stimulation threshold to evoke a spreading depression was elevated by more than 2-fold, the frequency of spreading depressions during continuous topical 1 M KCl was reduced by ∼40%, and propagation speed of spreading depression was reduced by ∼15%. This effect developed within 30 minutes after vagus nerve stimulation and persisted for more than 3 hours. Noninvasive transcutaneous vagus nerve stimulation was as efficacious as direct invasive vagus nerve stimulation, and the efficacy did not differ between the ipsilateral and contralateral hemispheres. Our findings provide a potential mechanism by which vagus nerve stimulation may be efficacious in migraine and suggest that susceptibility to spreading depression is a suitable platform to optimize its efficacy.

  17. Group interest versus self-interest in smallpox vaccination policy.

    PubMed

    Bauch, Chris T; Galvani, Alison P; Earn, David J D

    2003-09-02

    The recent threat of bioterrorism has fueled debate on smallpox vaccination policy for the United States. Certain policy proposals call for voluntary mass vaccination; however, if individuals decide whether to vaccinate according to self-interest, the level of herd immunity achieved may differ from what is best for the population as a whole. We present a synthesis of game theory and epidemic modeling that formalizes this conflict between self-interest and group interest and shows that voluntary vaccination is unlikely to reach the group-optimal level. This shortfall results in a substantial increase in expected mortality after an attack.

    2010-01-01

    Acupuncture is used widely in oriental medicine. But it is difficult to stimulate continuously or intermittently in daily life with conventional acupuncture. An acupoint stimulation device using focused ultrasound has been developed. Because the device size is about 6 mm in diameter, it can be easily put on the skin during daily life. Appropriate stimulation intensity and pattern can be chosen by changing driving voltage and pattern. In this paper, we stimulated acupoints with this device and measured the blood flow volume of brachial artery. As a result, the blood flow volume increased significantly as well as acupuncture. Because the device stimulate acupoints with intactness of skin, advantages of this device is free from infection and fear and pain by insertion of acupuncture needles.

    2016-05-13

    The processing of nociceptive, visual, vibrotactile, thermal and acoustic stimuli during sleep has been extensively investigated in the past. Recently, interest has focused on the impact of olfactory stimulation on sleep. In contrast to all other sensory systems, olfactory stimulation does not lead to an increased arousal frequency, regardless of hedonicity and concentration. The impact of the second chemosensory system, gustation, on sleep however has not been investigated to date. Twenty-one normosmic and normogeusic volunteers of both genders, aged 19-33 years, participated in the trial. Stimulation was performed with a gustometer using the following aqueous solutions: saccharose 20% (sweet), sodium chloride (NaCl) 7.5% (salty), citrate 5% (sour), and quinine 0.02% (bitter). A tasteless solution was used as negative control. Capsaicin, a strong trigeminal stimulus, served as positive control. Primary outcome was arousal frequency per stimulus in each sleep stage, as assessed with polysomnography. The frequency of arousals decreased in deeper sleep stages (N1: 211 arousals of 333 stimuli=63%, N2: 676/2728=25%, N3: 43/1378=3%, REM: 57/1010=6%). Statistically significant differences in terms of arousal frequency were found in N2 between the negative control and NaCl 100 μl (p<0.001), saccharose 100 μl, citrate 50 μl & 100 μl, and quinine 100 μl (p<0.05). Capsaicin led to complete awakenings in 94% of stimuli (30/32). These results demonstrate that gustatory stimulation during sleep induces arousals depending on stimulus intensity and sleep stage, which is different to olfactory stimulation and may be related to differences in central processing of the two chemosensory systems.
