Diblock copolymers of 4-vinylpyridine (4VP) and sodium methacrylate (MANa) have been synthesized and tested as dispersants for aqueous dispersions (80 wt % solid) of alumina-coated titanium dioxide. P4VP is strongly anchored onto the pigment surface. The molecular composition of the block copolymers has an effect on the amount of copolymer required for imparting good stability to the slurry. Where the two parent triblock copolymers are concerned, triblocks consisting of PMANa outer blocks have a stabilizing efficiency comparable to the diblock copolymers, whereas the reverse structure is much less efficient. In the case of a nonblock distribution of 4VP and MANa in the copolymer chains, the stabilization effect is lost. Finally, the comparison of different stabilizing blocks attached to the same anchoring block confirms that the electrosteric stabilization mechanism is superior to the steric stabilization mechanism. A decrease in the anchoring strength of the diblocks has a deleterious effect on the dispersion stability. [less ▲]

The provision of tailor made care, the search for cost containment and European harmonisation and unification have stimulated insurers, providers, patients and governments throughout Europe to seek for opportunities to establish new health care markets. The opening up of cross border care markets presents a good example. These markets offer health care services and products to patients in other countries than the nation which covers their residency or insurance. Although there are clear economic motives for cross border care, the number of patients which actually (can) cross borders is relatively limited: practice proves that current institutional frameworks can block patient flows. This raises the question how and which institutional frameworks have to be present or (re)designed in order to develop and establish an effectively functioning cross border health care market. This paper analyses this question in order to derive lessons and recommendations for future European harmonisation with regard to health care. Using a theoretical framework, which displays the economic motives, obstacles and possible institutional alternatives for cross border care, the conditions for the development and establishment of an effectively functioning health care market between the Netherlands and Belgium is explored. Using cross border care for rheumatological patients as a point of reference, it is shown that current regulations can hinder patients as well as care givers to engage in cross border care. On the basis of our framework, the consumption of Belgians consuming cross border care in the Netherlands is expected to be higher in comparison to the number of Dutch patients who consume care in Belgium. Conflicting interests among private and public specialists, general and academic hospitals, insurance companies and national government policies are also important stumbling blocks for cross border care. Our analysis shows that the most effective institutional frameworks include those that have a functional regional design: they offer the best opportunity to minimize on transaction costs and maximize the degree of tailor made care.

Abstract Aims: The objective of this study was to assess prospectively the outcomes of extra-narrow diameter implants (XNDI) placed in teenage patients as a temporary restorative option. Material and Methods: Twenty consecutive young patients presenting one or several missing teeth received XNDI that were immediately restored with composite, Polymethylmethacrylate (Acrylic) or ceramic crown. Clinical and radiographical outcomes were assessed for a minimum follow-up period of 1 year. Additionally, each patient completed retrospectively a satisfaction questionnaire using Visual Analog Scale (VAS). Results: A total of 30 implants were placed and followed for a period of 1–7.4 years (mean: 3.59 years). One implant failed after 3 weeks and was replaced successfully. No further biological complications occurred during the follow-up period, leading to an implant survival rate of 96.6%. The patient satisfaction evaluations displayed high levels of comfort and function. Conclusion: Immediately restored XNDI to replace missing teeth on teenager patients seems to be an effective temporary restorative option to replace missing teeth in young patients. Composite or ceramic crowns should be preferred. Clinical trials with long-term follow-ups and the assessment of passive egression are needed. [less ▲]

The aim of this study was to investigate the effectiveness of the attention training technique (ATT) on the frequency of intrusive thoughts experienced by a person with schizophrenia in her daily life. The attentional procedure was designed to attenuate self-focused attention and to reinforce attentional control and consisted of auditory external exercises. Homework practice was included to promote transfer to everyday life. The efficacy and specificity of the ATT were assessed with cognitive, functional, and control measures. The impact of ATT on symptomatology, work functioning, and self-esteem was also measured. Postrehabilitation results showed that, after nine training sessions, there was a reduction in intrusive thoughts for the cognitive and ecological outcome measures. Selective attention, attention switching, and resistance to distractive interference specifically improved. The person reported a reduction in intrusive thoughts in her daily life. In addition, positive symptoms decreased. Finally, a 6-month follow-up assessment revealed the maintenance of most of the beneficial effects in daily life. [less ▲]

Twenty six patients with dysphonia (different etiologies) were submitted to a voice therapy program involving the use of Eutony. In order to assess its efficacy, pre and post-treatment audio recordings were analysed and submitted to perceptual rating using GRBAS-I scale and acoustical analysis of fundamental frequency, jitter and shimmer. Aerodynamic data (Maximum Phonation Time & Estimated Subglottic Pressure) were also included in the voice quality assessment protocol. In addition , a questionnaire was sent to all patients to collect self-evaluation of voice quality and therapy outcomes. The study revealed a significant improvement lasting in time for two acoustic parameters : Jitter and Shimmer and five perceptual parameters : Grade, Roughness, Breath, Asthenia and Strain. Aerodynamic data showed slight improvements but no significant changes. Self evaluation questionnaires also tend to strengthen positive effects of therapy. Thus, this study supports the use of Eutony in vocal therapy for dysphonia. Its effects were shown to be measurable with both acoustical analysis and perceptual rating of voice quality. [less ▲]

BACKGROUND: Actinic prurigo is a specific familial photodermatosis of uncertain pathogenesis. OBJECTIVE: Our purpose was to investigate the immunohistologic presentation of actinic prurigo to explore the involved pathomechanisms. METHODS: The present immunohistochemical study was performed on biopsy specimens from 20 Mexican patients presenting with a severe and perennial form of the disease. RESULTS: The dense inflammatory infiltrate was composed predominantly of helper T type 1 lymphocytes admixed with scattered B-cell lymphoid follicles and numerous dermal dendrocytes. Keratinocytes contained abundant tumor necrosis factor-alpha and calprotectin. CONCLUSION: In subjects genetically predisposed to actinic prurigo, ultraviolet light may trigger excessive tumor necrosis factor-alpha production by keratinocytes whose sustained release in turn exerts its proinflammatory activity and deleterious epidermal effects. Such a cascade of events is in line with the therapeutic benefit already reported when thalidomide is used to treat actinic prurigo. [less ▲]

A description is given of the small-scale steadstate tests made by Hasemi in Japan with the aim of measuring the heat flux transmitted by a localised fire to the ceiling or to a beam located above the fire. The parameters that influence the heat flux have been mentionned and an empirical model has been proposed, allowing the prediction of the heat flux.It is shown here how the model has been applied to full-scale transient fires. The model allows the calculation of the transient temperature in steel beams with a reasonable accuracy. [less ▲]

The influence of training on cardiorespiratory and thermoregulatory adaptations to exercise was studied in 2 healthy race ponies (age : 3.5 and 5 years; weight : 270 and 295 kg). Respiratory airflow (V), tidal volume (VT), electrocardiogram and rectal temperature were simultaneously recorded before, during and alter a standardized exercise which consisted of 3 min walking (1.5 m.sec -1), 3 min slow trotting (3.0 m.sec-1) and 3 min fast trotting (3.5 m.sec-1). These parameters were recorded 4 times, i.e. before (test 1), during (test 2 and 3) and 2 weeks alter (test 4) a 4 week-period of training. Respiratory frequency (f), VT, peak inspiratory and expiratory V, minute volume (Ve), heart rate (H.R.) and rectal temperature changes were calculated on the basis of the collected data. For a given workload, Ve was increased and H.R. decreased during test 2 and 3. These adaptations to training persisted alter the 2 week-period of detraining. Neither Ve nor H.R. recoveries were changed during the whole experimental period. On the other hand, f measured both during exercise and recovery was subject to great variations, obviously independent of the state of training. Lastly, the exercise-induced hyperthermia was reduced alter the training period. This thermoregulatory changes was reversed alter detraining. The results of this preliminary study must be taken with cautions because of the small number of animals used. Nevertheless, they suggested that (1) f is a poor indication of the ventilation, (2) measurements of Ve and HR during a standardized exercise may give a good estimation of the fitness of a horse, (3) on the opposite both parameters measured during recovery seemed to be poorly correlated with the state of training.

Background: Automatic motor inhibition is an important and adaptive process through which an activated motor plan is suppressed if the movement is not intended to be executed. Neuronal networks are characterized by oscillatory activity. In the brain, a large variety of rhythms have been described that differ in their frequency, origin and reactivity to changes in task demands. Recent studies have demonstrated that active cortical networks are susceptible to weak sinusoidal perturbations of exogenous electric fields. Objective/Hypothesis: The aim of this study was to investigate the frequency-specific effect of transcranial alternate current stimulation (tACS) over the automatic control of movement in healthy volunteers. We hypothesized that applying two different tACS frequencies during a visuo-motor task would result in different behavioural effects and in diverse modulation of cortical excitability. Methods: In this study we used tACS to interact non-invasively with the ongoing task-related oscillatory activity. Stimulation was delivered at alpha (10 Hz) and beta (20 Hz) frequency over the supplementary motor area and the primary motor cortex (SMA-M1) connections, which are part of the BG-cortical motor loop, during the execution of the subliminal masked prime task. We measured the effects on task performance and on motor cortex corticospinal excitability by means of motor evoked potentials (MEPs) evoked by transcranial magnetic stimulation (TMS). Results: Results indicate a specific effect of 10 and 20-Hz tACS on functional inhibition in the SMA-M1 circuit. Behaviorally there is an interference in task-related automatic inhibition: 10 Hz tACS reduced the automatic inhibition. In contrast 20 Hz tACS increased the automatic inhibition. At a neurophysiological level there is a modulation in excitability of M1: 20 Hz tACS reduced MEP amplitudes, whereas there was no change after 10 Hz tACS. Conclusion(s): The current study provides novel evidence that automatic mechanisms of motor behaviour can be modulated by imposing synchronized electrical oscillatory activity upon motor cortical regions. Our study has important implications for cognitive neuroscience studies suggesting that the use tACS might offer the possibility to demonstrate a causal link between endogenous brain oscillations, specific exogenous alternate current frequencies and specific cognitive processes.
