Dynamic and Functional Approach to Human Memory in the Brain: A Clinical Neuropsychological Perspective

The way how cognition is conceived and represented in brain functioning will directly impact clinical investigations of people with cognitive difficulties. This is particularly evident in the field of clinical neuropsychology where methodologies and tools are justified on a fundamental level by the theoretical foundations adopted. The present article outlined how the dominant influences of structural and anatomo-clinical theories of memory have led to a particular conception of clinical investigations. We propose to reconsider these dominant methods in favor of a more dynamic and functional representation of memory that would be clinically more appropriate. More precisely, we argued that relying exclusively on a particular memory conception (i.e., structural) may not be sufficient considering the range of real-life variables affecting a patient’s memory. By extracting clinically meaningful information in more functional and dynamic memory conceptions, we also aim at underlining the potentials advantages of such theories in facilitating personalized assessments and follow up of patients in clinical neuropsychology. We suggest that a dynamic, functional, and integrative conception of memory would be more coherent with the trend in clinical neuropsychology to promote a more collaborative interaction between the clinician and the patient. Finally, considering the absence of empirical studies on the possible benefits of implementing such recent memory concepts in clinical practice, we encourage researchers and clinicians to test in the field of clinical neuropsychology, the usefulness and explanatory power of more dynamic and functional representation of memory in order to objectively demonstrate its validity outside the research loop.
Spectral profiling of autofluorescence associated with lipofuscin, Bruch's Membrane, and sub-RPE deposits in normal and AMD eyes.

PURPOSE To compare the autofluorescence spectra of retinal pigment epithelium (RPE)-associated lipofuscin, Bruch's membrane, and sub-RPE deposits (drusen and basal laminar-linear deposits) in eyes of donors with age-related macular degeneration (AMD) against eyes of age-matched control donors. METHODS Cryosections were cut from the maculae of unfixed human donor eyes with AMD or from age-matched control eyes. Tissues were excited at wavelengths of 364, 488, 568, and 633 nm. Emission spectra were collected with a confocal microscope equipped with a spectrophotometric detector at 10-nm wavelength intervals between 400 and 800 nm. RESULTS RPE lipofuscin had strong autofluorescent emissions that were excited at all wavelengths. Bruch's membrane exhibited strong autofluorescence with an emission peak of 485 +/- 5 nm when excited with 364-nm light. At 488-, 568-, and 633-nm excitations, Bruch's membrane and sub-RPE deposits in normal eyes exhibited minimal autofluorescence. In AMD eyes, however, both the 364- and 488-nm excitation wavelengths stimulated substantial blue-green emissions from sub-RPE deposits and Bruch's membrane, with average pixel intensities substantially exceeding that elicited in the yellow-orange range by RPE lipofuscin. CONCLUSIONS These data suggest that an increase in blue-green autofluorescence of Bruch's membrane relative to the yellow-orange autofluorescence of RPE-associated lipofuscin is associated with AMD. Knowledge of these spectra will be useful in evaluating animal models of macular degenerative disease and in diagnosis of AMD, and will provide a novel signature for further analysis of the molecular entities emitting these fluorescent signatures.
Posttraumatic stress and depressive reactions among children and adolescents after the 1999 earthquake in Ano Liosia, Greece.

OBJECTIVE This study evaluated the severity of posttraumatic stress and depressive reactions among children and adolescents 3 months after the 1999 earthquake in Ano Liosia, Greece, and additionally assessed the relationship of these reactions to objective and subjective features of earthquake exposure, sex, school level, postearthquake difficulties, death of a family member, and thoughts of revenge. METHOD This school-based study of 1,937 students was conducted in two differentially exposed cities (Ano Liosia, at the epicenter, and Dafni, 10 kilometers from the epicenter) with an earthquake exposure questionnaire, the UCLA Posttraumatic Stress Disorder (PTSD) Reaction Index, and the Depression Self-Rating Scale. RESULTS Endorsement of earthquake-related exposure items between the two cities was congruent with the extent of earthquake impact in each city. Median PTSD Reaction Index scores were significantly higher in Ano Liosia. The estimated rates of PTSD and clinical depression for both cities combined were 4.5% and 13.9%, respectively. Depression, subjective and objective earthquake-related experiences, and difficulties at home accounted for 41% of the variance in severity of PTSD reactions. PTSD score was the single most powerful variable predicting depression (36% of the variance), with only sex making a small but significant additional contribution. CONCLUSIONS This study demonstrated the feasibility of conducting large-scale school-based postdisaster mental health screening for planning intervention strategies. The present findings regarding PTSD and depression indicate the need to provide targeted specialized postdisaster mental health services to subgroups with significant levels of posttraumatic stress and depressive reactions after an earthquake of moderate intensity.
Metoprolol and propranolol treatment in carbon tetrachloride-induced hepatic injury.

The effects of beta 1-selective metoprolol (CAS 37350-58-6) and the nonselective beta-adrenoceptor antagonist propranolol (CAS 525-66-6) were investigated in healthy and CCl4 damaged male rats. Treatments were performed for 16 days, orally with dosages reducing heart beat/min by 25% (metoprolol 10 mg/kg, propranolol 1 mg/kg). Liver glycogen content was not influenced by either beta-blocker in healthy animals. CCl4-induced loss of glycogen was equally moderated by metoprolol and propranolol. Blood glucose increased in metoprolol treated healthy and liver damaged rats after a single dosage likewise following prolonged treatment. Propranolol was without effect on blood glucose level. Cytochrome P-450 decline in microsomal fraction was greater in metoprolol, than in propranolol treated healthy animals. However, the severe fall elicited by liver injury was moderated by metoprolol and normalised by propranolol. Cytochrome b5 seems to be involved in metoprolol metabolism. Cytochrome P-450-dependent aminopyrine-N-demethylase was impeded by metoprolol in animals with healthy liver. The serious inhibition caused by CCl4 was moderated by metoprolol and with a better result by propranolol. The high serum bilirubin level in liver lesion was lowered by metoprolol and particularly by propranolol. Neither phase I metabolic process aminopyrine-N-demethylation nor phase II glucuronidation were normalised. A comparison of this data with the results of a previous 12-day treatment schedule indicates that no changes in efficacy occurred with longer treatment. The present results pertain to the importance of the selection of beta-adrenoceptor blocker in liver lesion. (ABSTRACT TRUNCATED AT 250 WORDS)
Énumération exhaustive et détection spécifique des analogies : étude pour les modèles de langue et la traduction automatique. (Complete Enumeration and Specific Detection of Proportional Analogies: Studies for Language Models and Machine Translation)

Ce travail de these s'inscrit dans le cadre de la traduction automatique. En etudiant les fondements de la traduction automatique par l'exemple, et plus particulierement le systeme Aleph, nous mettons en evidence le probleme de la selection des exemples. Le systeme Aleph emploie exclusivement l'analogie afin de produire de nouvelles phrases et de nouvelles traductions. Le probleme est de selectionner les phrases dans un grand corpus d'exemples afin de produire de nouvelles phrases par analogie. Notre premier apport consiste en l'elaboration d'une methode permettant d'enumerer l'integralite des analogies entre chaines d'un texte. Cette methode nous permet ensuite de mettre en œuvre une etude statistique des analogies les plus frequentes entre trigrammes de mots et de mettre en evidence les patrons d'analogie les plus frequents. Ces resultats permettent alors de concevoir une nouvelle methode de lissage d'un modele de langue trigramme base sur un petit nombre d'analogies. Nos experiences montrent que cette methode est tres competitive vis-a-vis des methodes classiques.
Biophysical properties and functional consequences of reactive oxygen species (ROS)‐induced ROS release in intact myocardium

Non‐Technical Summary Oxidative stress is a hallmark of various cardiovascular disorders that results in cellular dysfunction and death. Reactive oxygen species (ROS)‐induced ROS release (RIRR) is a fundamental mechanism which amplifies ROS levels within the cardiomyocyte resulting in cellular oxidative stress. Despite elegant studies describing the phenomenon of RIRR in isolated myocytes, its biophysical properties and functional consequences in intact myocardium remain unclear. Here, we use ROS imaging to extend the concept of RIRR to the level of the intact heart. We establish regenerative superoxide production as the mediator of RIRR‐related arrhythmias and reveal their strong dependence on a key mitochondrial channel, known as the inner membrane anion channel (IMAC). We demonstrate the efficacy of suppressing RIRR and related arrhythmias either by pharmacologically blocking IMAC or scavenging ROS using a synthetic superoxide dismutase/catalase mimetic.
Toward optimization of AgoshRNA moleculesthat use a non-canonical RNAi pathway: Variations in the top and bottom base pairs

Short hairpin RNAs (shRNAs) are widely used for gene knockdown by inducing the RNA interference (RNAi) mechanism. The shRNA precursor is processed by Dicer into small interfering RNAs (siRNAs) and subsequently programs the RNAi-induced silencing complex (RISC) to find a complementary target mRNA (mRNA) for post-transcriptional gene silencing. Recent evidence indicates that shRNAs with a relatively short basepaired stem bypass Dicer to be processed directly by the Ago2 nuclease of the RISC complex. We named this design AgoshRNA as these molecules depend on Ago2 both for processing and subsequent silencing activity. This alternative AgoshRNA processing route yields only a single active RNA strand, an important feature to restrict off-target effects induced by the passenger strand of regular shRNAs. It is therefore important to understand this novel AgoshRNA processing route in mechanistic detail such that one can design the most effective and selective RNA reagents. We performed a systematic analysis of the optimal base pair (bp) composition at the top and bottom of AgoshRNA molecules. In this study, we document the importance of the 5′ end nucleotide (nt) and a bottom mismatch. The optimized AgoshRNA design exhibits improved RNAi activity across cell types. These results have important implications for the future design of more specific RNAi therapeutics.
The coordination of posture and voluntary movement in patients with cerebellar dysfunction

Postural adjustments associated with the task of rising on tiptoes were investigated in a reaction time paradigm in 10 normal subjects and 18 patients with cerebellar disorders. Cerebellar dysfunction was due to either degenerative cerebellar disease, tumor, or ischemia. Displacements of the center of foot pressure (CFP) were recorded. The task, accomplished by the triceps surae muscle (executional activity, mean latency of 411 ms), is mechanically effective only if the center of gravity has been shifted forward in advance. To this effect, a phasic burst of preparatory EMG activity in the tibialis anterior normally occurs at a mean latency of 163 ms, shifting the center of gravity forward. Shortly thereafter, activity of the quadriceps femoris (175 ms) extends the knee and aids the forward shift of the center of gravity. Different aspects of this motor sequence were disturbed in individual patients: Latencies of preparatory and executional activity were uncorrelated in 15 of the 18 patients. Executional (n = 16) or preparatory (n = 13) EMG activity was tonic instead of phasic. Latencies of either preparatory or executional EMG activities or both were prolonged (n = 10). The time interval between motor preparation and execution was increased (n = 9). The trial‐to‐trial variability of biomechanical parameters and EMG latency was increased. Preparatory EMG activity in the quadriceps was entirely missing (n = 9), resulting in knee bending at the unsuccessful attempt to rise on tiptoes. Patients who were most severely affected had no preparatory activity at all (n = 2), and therefore were unable to perform the task. In conclusion, the cerebellum contributes to the scaling of size and duration of preparatory and executional motor activity and controls their temporal relationships.
Pandemic H1N1 Influenza A Viruses Are Resistant to the Antiviral Activities of Innate Immune Proteins of the Collectin and Pentraxin Superfamilies

Acquired immune responses elicited to recent strains of seasonal H1N1 influenza viruses provide limited protection against emerging A(H1N1) pandemic viruses. Accordingly, pre-existing or rapidly induced innate immune defenses are of critical importance in limiting early infection. Respiratory secretions contain proteins of the innate immune system, including members of the collectin and pentraxin superfamilies. These mediate potent antiviral activity and act as an initial barrier to influenza infection. In this study, we have examined the sensitivity of H1N1 viruses, including pandemic virus strains, for their sensitivity to collectins (surfactant protein [SP]-D and mannose-binding lectin [MBL]) and to the pentraxin PTX3. Human SP-D and MBL inhibited virus-induced hemagglutinating activity, blocked the enzymatic activity of the viral neuraminidase, and neutralized the ability of H1N1 viruses to infect human respiratory epithelial cells in a manner that correlated with the degree of glycosylation in the globular head of the hemagglutinin. Recent seasonal H1N1 viruses expressed three to four N-glycosylation sequons on the head of hemagglutinin and were very sensitive to inhibition by SP-D or MBL, whereas A(H1N1) pandemic viruses expressed a single N-glycosylation sequon and were resistant to either collectin. Of interest, both seasonal and pandemic H1N1 viruses were resistant to PTX3. Thus, unlike recent seasonal H1N1 strains of influenza virus, A(H1N1) pandemic viruses are resistant to the antiviral activities of innate immune proteins of the collectin superfamily.
Anti-tuberculosis drug resistance in Portugal.

SETTING A survey based upon a representative sample of smear-positive pulmonary tuberculosis patients was undertaken in Portugal, as part of the World Health Organization's Global Project on Anti-Tuberculosis Drug Resistance Surveillance. OBJECTIVE To determine the level of primary antituberculosis drug resistance at both national and regional levels, and to assess its relative weight within the performance of the National Tuberculosis Programme (NTP). DESIGN Mycobacterium tuberculosis isolates from 1,105 patients with smear-positive pulmonary tuberculosis admitted to 46 randomly stratified treatment centres all over mainland Portugal were submitted to susceptibility testing with four drugs. Human immunodeficiency virus (HIV) testing was included in the patients' evaluation scheme. RESULTS Of the strains isolated, 197 (17.8%) were resistant to at least one drug. Primary resistance to isoniazid was 7.7% and to rifampicin 1.9%. Acquired drug resistance was 39.2% in total, any acquired resistance to isoniazid 31.1% and to rifampicin 20.9%. Primary multidrug resistance (MDR) was 1.8% and acquired MDR was 20.9%. HIV testing was positive in 29.2% of MDR-TB cases. CONCLUSIONS Drug resistance in Portugal is high. Primary MDR and particularly acquired MDR occur in a high proportion of cases, indicating a need for improvement in NTP performance.

Factors influencing participation in cardiac rehabilitation programmes after referral and initial attendance: qualitative systematic review and meta-synthesis

Background: Greater participation in cardiac rehabilitation improves morbidity and mortality in people with coronary heart disease, but little is understood of patients’ decisions to participate. Methods: To develop interventions aimed at increasing completion of programmes, we conducted a qualitative systematic review and meta-synthesis to explore the complex factors and processes influencing participation in cardiac rehabilitation programmes after referral and initial access. To be included in the review, studies had to contain a qualitative research component, population specific data on programme participation in adults >18 years, and be published ≥1995 as full articles or theses. Ten databases were searched (31 October 2011) using 100+ search terms. Results: Of 2264 citations identified, 62 studies were included involving: 1646 patients (57% female; mean age 64.2), 143 caregivers, and 79 professionals. Patients’ participation was most strongly influenced by perceptions of the nature, suitability and scheduling of programmes, social comparisons made possible by programmes, and the degree to which programmes, providers, and programme users met expectations. Women’s experiences of these factors rendered them less likely to complete. Comparatively, perceptions of programme benefits had little influence on participation. Conclusions: Factors reducing participation in programmes are varied but amenable to intervention. Participation should be viewed as a ‘consumer behaviour’ and interventions should mobilize family support, promote ‘patient friendly’ scheduling, and actively harness the social, identity-related, and experiential aspects of participation.
Maternal pollen allergy may be more important than birch pollen exposure during pregnancy for atopic airway disease in the child

In 1993 extremely high levels of birch pollen were recorded in Stockholm, Sweden. We investigated the effects of this exposure on sensitization and development of atopic airway disease in children. The aim of this study was to assess the influence of maternal birch sensitization and symptoms of pollen allergy, as well as exposure to birch pollen during pregnancy, on sensitization and development of atopic airway disease in children. A total of 387 children with atopic heredity (70% had atopic mothers) and born in Stockholm 1993 or 1994 were investigated at age 4.5–5 yr. The children were examined and skin prick tested with inhalant and food allergens. IgE‐antibodies against birch pollen and recombinant birch pollen allergen were analyzed in serum. The same tests were performed on the mothers. Children of mothers with symptoms of pollen allergy more often showed symptoms of rhinoconjunctivitis at age 4.5–5, after both high dose [Odds ratio (OR) 5.3; 95% confidence interval (CI): 2.0–13.7] and low dose (OR 4.0; 95% CI: 1.5–10.9) exposure to birch pollen during pregnancy. Similar tendencies were noted for children of mothers sensitized to birch, where stronger effects were suggested in boys (OR 3.8; 95% CI: 1.3–11.5) than in girls (OR 1.2; 95% CI: 0.2–5.5) in the high‐dose exposed group. For asthma symptoms and sensitization to birch in the children the results were less consistent. It may be concluded that, maternal pollen allergy seems to have a stronger influence on the development of rhinoconjunctivitis in children with a family history of atopy than the degree of allergen exposure during pregnancy.
Comparison of Vibrio cholerae O139 with V. cholerae O1 classical and El Tor biotypes

Vibrio cholerae O139 is a recently identified non-O1 V. cholerae strain responsible for outbreaks of epidemic cholera in India, Bangladesh, and Thailand in the past 2 years. Other workers have demonstrated the presence of the cholera toxin genetic element in V. cholerae O139, unlike the situation for other non-O1 V. cholerae strains. We sought to compare further this strain with strains of V. cholerae O1, classical and El Tor biotypes, by classic microbiologic methods, Southern blot analysis for restriction fragment length polymorphisms with probes for iron-regulated genes of V. cholerae O1, and comparisons of outer membrane protein profiles. Our results were similar for V. cholerae O139 and the El Tor biotype of V. cholerae O1, with the exception of the constitutive expression in V. cholerae O139 of OmpS, an outer membrane protein that was maltose inducible in comparison strains of V. cholerae O1.
Binocular and Monocular Detection of Gabor Patches in Binocular Two-Dimensional Noise

Contrast thresholds for detecting sine-wave Gabor patches in two-dimensional externally added random-pixel noise were measured. Thresholds were obtained for monocular and binocular signals in the presence of spatial correlated (identical) and uncorrelated (independent) noise in the two eyes. Measurements were obtained at four different spectral densities of noise (including zero). Thresholds were higher for monocular stimuli than for binocular, and higher in the presence of correlated noise compared to uncorrelated noise. The magnitude of binocular summation, similar in correlated and uncorrelated noise, decreased with increasing noise strength. The independent contributions of internal noise and sampling efficiency to detection were analysed. Sampling efficiencies were higher for binocular than for monocular viewing for both types of noise, with values being higher with uncorrelated noise. Binocular stimuli showed a lower equivalent noise level compared to the mean monocular case for both types of noise.
