A Psychoanalytic Study of Migration: Its Normal and Pathological Aspects

Without maintaining that it always follows the same steps, we could say that the migratory process passes through several phases. The feelings that prevail are those of intense sorrow for all that has been abandoned or lost, fear of the unknown, and the very profound experiences of loneliness, privation, and helplessness. Paranoid, confusional, and depressive anxieties occupy the scene in turn. This stage may be followed or replaced by a manic state in which the immigrant minimizes the transcendental significance of the change in his life or, on the contrary, magnifies the advantages of the change and overvalues everything in the new situation, disdaining what has been lost. After a variable period of time, nostalgia appears, and sorrow for the lost world. The immigrant begins to recognize feelings previously dissociated or denied and becomes capable of "suffering" his pain ("growing pains") while, at the same time, he becomes more accessible to the slow and progressive incorporation of elements of the new culture. The interaction between his internal and external world becomes more fluid. Recovery of the pleasure of thinking and desiring and of the capacity for making plans for the future, in which the past is regarded as such and not as a "lost paradise" where one constantly longs to return. In this period, it could be considered that mourning for the country of origin has been worked through to the maximum extent possible, facilitating integration of the previous culture into the new culture, without the need to renounce the old. All of this promotes an enrichment of the ego and the consolidation of a more evolved sense of identity.
An evaluation of the possible carcinogenicity of bisphenol A to humans.

Bisphenol A (BPA) is a monomer component of polycarbonate plastics and epoxy resins. These resins are used in numerous consumer products, including food-contact plastics. There has been considerable scientific debate about the relevance to humans of reported estrogenic actions of BPA. Much less attention has been focused on the carcinogenic potential of BPA. The carcinogenic potential of BPA was assessed through a review of metabolic data, genetic toxicity studies, long-term toxicity/carcinogenicity studies, and estimates of consumer exposure. Following a weight-of-evidence approach as recommended by IARC and U.S. EPA, it was concluded that BPA is not likely to be carcinogenic to humans. The bases for this conclusion included: (a) the results of an NTP study which provided no substantive evidence to indicate that BPA is carcinogenic to rodents; (b) the lack of activity of BPA, at noncytotoxic concentrations, in standard in vitro genetic toxicity tests; (c) the lack of genotoxic activity of BPA in a GLP-compliant in vivo mouse micronucleus assay; and (d) the results of metabolism studies showing BPA is rapidly glucuronidated without evidence of formation of potentially reactive intermediates, except possibly at high doses that could saturate detoxication pathways. In addition, exposure assessment reveals that current use of BPA would result in only a trivial human exposure.
Duration of Sleep Inertia after Napping during Simulated Night Work and in Extended Operations

Due to the mixed findings of previous studies, it is still difficult to provide guidance on how to best manage sleep inertia after waking from naps in operational settings. One of the few factors that can be manipulated is the duration of the nap opportunity. The aim of the present study was to investigate the magnitude and time course of sleep inertia after waking from short (20-, 40- or 60-min) naps during simulated night work and extended operations. In addition, the effect of sleep stage on awakening and duration of slow wave sleep (SWS) on sleep inertia was assessed. Two within-subject protocols were conducted in a controlled laboratory setting. Twenty-four healthy young men (Protocol 1: n = 12, mean age = 25.1 yrs; Protocol 2: n = 12, mean age = 23.2 yrs) were provided with nap opportunities of 20-, 40-, and 60-min (and a control condition of no nap) ending at 02:00 h after ∼20 h of wakefulness (Protocol 1 [P1]: simulated night work) or ending at 12:00 h after ∼30 h of wakefulness (Protocol 2 [P2]: simulated extended operations). A 6-min test battery, including the Karolinska Sleepiness Scale (KSS) and the 4-min 2-Back Working Memory Task (WMT), was repeated every 15 min the first hour after waking. Nap sleep was recorded polysomnographically, and in all nap opportunities sleep onset latency was short and sleep efficiency high. Mixed-model analyses of variance (ANOVA) for repeated measures were calculated and included the factors time (time post-nap), nap opportunity (duration of nap provided), order (order in which the four protocols were completed), and the interaction of these terms. Results showed no test x nap opportunity effect (i.e., no effect of sleep inertia) on KSS. However, WMT performance was impaired (slower reaction time, fewer correct responses, and increased omissions) on the first test post-nap, primarily after a 40- or 60-min nap. In P2 only, performance improvement was evident 45 min post-awakening for naps of 40 min or more. In ANOVAs where sleep stage on awakening was included, the test x nap opportunity interaction was significant, but differences were between wake and non-REM Stage 1/Stage 2 or wake and SWS. A further series of ANOVAs showed no effect of the duration of SWS on sleep inertia. The results of this study demonstrate that no more than 15 min is required for performance decrements due to sleep inertia to dissipate after nap opportunities of 60 min or less, but subjective sleepiness is not a reliable indicator of this effect. Under conditions where sleep is short, these findings also suggest that SWS, per se, does not contribute to more severe sleep inertia. When wakefulness is extended and napping occurs at midday (i.e., P2), nap opportunities of 40- and 60-min have the advantage over shorter duration sleep periods, as they result in performance benefits ∼45 min after waking.
Um outro "Quarto Poder": imprensa e compromisso político no Brasil

"A eleicao das reformas"; "Por que o Brasil desconfia dos politicos". Os titulos de capa das revistas Epoca e Veja, em suas edicoes imediatamente anteriores as eleicoes de 1998, constituem um bom ponto de partida para discutir a questao do papel politico da imprensa no Brasil. O que estes titulos sugerem? A luz do debate atual sobre o tema poderiamos dizer que o titulo de Epoca sugere uma atitude francamente governista da revista, enquanto haja reflete velhos preconceitos contra os politicos em geral e (se observarmos o corpo da materia) contra os parlamentares em particular. E nao estariamos errados. Entretanto, poderiamos encontrar outras licoes nesses mesmos enunciados. Epoca e Veja nao estao apenas se pronunciando a favor do governo. ou manifestando desconfianca com relacao ao Congresso Nacional; elas estao tambem demarcando o espaco de uma competencia especifica: o de fornecer uma interpretacao "independente" da cena politica transcendente em relacao as perspectivas particulares dos agentes politicos envolvidos.
Exposure to Androstenes Influences Processing of Emotional Words

There is evidence that human-produced androstenes affect attitudinal, emotional and physiological states in a context-dependent manner, suggesting that they could be involved in modulating social interactions. For instance, androstadienone appears to increase attention specifically to emotional information. Most of the previous work focused on one or two androstenes. Here, we tested whether androstenes affect linguistic processing, using three different androstene compounds. Participants (90 women and 77 men) performed a lexical decision task after being exposed to an androstene or to a control treatment (all compounds were applied on the philtrum). We tested effects on three categories of target words, varying in emotional valence: positive, competitive, and neutral words (e.g., hope, war, and century, respectively). Results show that response times were modulated by androstene treatment and by emotional valence of words. Androstenone, but not androstadienone and androstenol, significantly slowed down the reaction time to words with competitive valence. Moreover, men exposed to androstenol showed a significantly reduced error rate, although men tended to make more errors than women in general. This suggests that these androstenes modulate the processing of emotional words, namely some particular lexical emotional content may become more salient under the effect of androstenes.
Nitrogen isotopes determination in natural gas: analytical method and first results on magmatic, hydrothermal and soil gas samples

A continuous-flow GC/IRMS technique has been developed to analyse δ15N values for molecular nitrogen in gas samples. This method provides reliable results with accuracy better than 0.15 ‰ and reproducibility (1σ) within±0.1 ‰ for volumes of N2 between 1.35 (about 56 nmol) and 48.9 μL (about 2 μmol). The method was tested on magmatic and hydrothermal gases as well as on natural gas samples collected from various sites. Since the analysis of nitrogen isotope composition may be prone to atmospheric contamination mainly in samples with low N2 concentration, we set the instrument to determine also N2 and 36Ar contents in a single run. In fact, based on the simultaneously determined N2/36Ar ratios and assuming that 36Ar content in crustal and mantle-derived fluids is negligible with respect to 36Ar concentration in the atmosphere, for each sample, the degree of atmospheric contamination can be accurately evaluated. Therefore, the measured δ15N values can be properly corrected for air contamination.
Subpopulations of Slowly Cycling Cells In S and G2 Phase In Mouse Epidermis

Evidence has been presented supporting the existence of heterogeneity in cell‐cycle progression in mouse epidermis, the present study was undertaken to characterize this heterogeneity in more detail. Hairless mice were continuously labelled with tritiated thymidine every 4 hr for 4 days. Basal cell suspensions were prepared from slices of mouse skin at intervals during the experiment and subjected to DNA flow cytometry. Cell‐cycle analysis was combined with sorting of cells from windows in G1, S and G2, phase, and the proportion of labelled cells within each window was determined in autoradiographs. Reanalysis and resorting to control the purity of sorted fractions were performed.
Sea Level Change in Hong Kong from Tide Gauge Records

The results from the study indicate that there is a rising trend of 1.9±0.4 mm per year in the sea level of Hong Kong. The effect of local atmospheric pressure variations on the amplitude of the annual sea level change is about 30% of the amplitude. It is also found that the interannual variations in the sea level of Hong Kong are related to El Nino and La Nina events that occur frequently in the tropical Pacific. It is projected from an extrapolation of the current trends of seal level rise and ground subsidence that the possible maximum relative mean sea level change will be as high as 50 cm in the next half century when considering the various temporal variations.
Genetic Diversity and Biochemical Characteristics ofTrichosporon asahii Isolated from Clinical Specimens, Houses of Patients with Summer-Type-Hypersensitivity Pneumonitis, and Environmental Materials

ABSTRACT Trichosporon asahii, which is distributed in the environment, is the major causative agent of the opportunistic infection trichosporonosis, and it also causes summer-type hypersensitivity pneumonitis (SHP). Random amplification of polymorphic DNA analysis was used to determine the intraspecies diversity of 39T. asahii isolates from clinical specimens, SHP patients' houses, and environmental materials. The three primers used revealed 46 polymorphic bands. A phenogram was generated by the unweighted pair-group method with arithmetic mean. Clinical isolates formed a cluster, characterized by a 90% matching coefficient, but they did not cluster with strains isolated from SHP patients' houses or environmental sources. In addition, the biochemical characteristics of 86 strains from three sources were examined with 31 compounds using an ID32C kit, and a phenogram was constructed. The phenogram consisted of three major clusters. Cluster I included most of the clinical SHP isolates, and cluster II included most of the environmental isolates. Cluster III contained only one strain. A remarkable difference was found in the abilities of the strains belonging to clusters I and II to utilize six compounds. These results suggest that the genetic diversity and biochemical characteristics of T. asahii seem to be related to the source of the isolate. We also found a specific DNA fragment for the clinical isolates and strains isolated from SHP patients' houses.
An FPGA-Based Instrument for En-Masse RRAM Characterization With ns Pulsing Resolution

An FPGA-based instrument with capabilities of on-board oscilloscope and nanoscale pulsing (70 ns @ ±10 V) is presented, thus allowing exploration of the nano-scale switching of RRAM devices. The system possesses less than 1% read-out error for resistance range between 1 kΩ to 1 MΩ, and demonstrated its functionality on characterizing solid-state prototype RRAM devices on wafer; devices exhibiting gradual switching behavior under pulsing with duration spanning between 30 ns to 100 μs. The data conversion error-induced degradation on read-out accuracy is studied extensively and verified by standard linear resistor measurements. The integrated oscilloscope capability extends the versatility of our instrument, rendering a powerful tool for processing development of emerging memory technologies but also for testing theoretical hypotheses arising in the new field of memristors.
Results of direct current electrical activation of failed-to-fertilize oocytes after intracytoplasmic sperm injection.

OBJECTIVE To assess the embryo formation rate after electrical activation on failed-to-fertilize oocytes after intracytoplasmic sperm injection (ICSI). STUDY DESIGN A prospective, randomized, experimental study was conducted in our research laboratory at the Reproductive Medicine Unit, Department of Obstetrics and Gynecology, Faculty of Medicine, Chulalongkorn University, between January and September 2004. One hundred failed-to-fertilize oocytes after ICSI were randomly assigned by stratified allocation according to oocyte grading before ICSI. Fifty unfertilized oocytes were activated with 3 consecutive 40-/microsec pulses of 1.5 kV/cm direct electrical current in buffer solution. The other 50 unfertilized oocytes, composing the control group, were treated in same way but without electrical activation. The embryo formation rates between the groups were compared. RESULTS Embryo formation rates in the electrically activated group were 80% as compared with 16% in the control group (p < 0.001). CONCLUSION Failed-to-fertilize oocytes after ICSI seem to be able to resume embryonic development after electrical activation.
Tensor modeling and signal processing for wireless communication systems. (Modélisation et traitement tensoriel du signal pour les systèmes de communication sans-fil)

Dans plusieurs applications de traitement du signal pour les systemes de communication sans fils, le signal recu est de nature multidimensionnelle et possede une structure algebrique multilineaire. Dans ce contexte, la decomposition tensorielle de type PARAFAC a fait l’objet de plusieurs travaux au cours des six dernieres annees. Il s’avere que des decompositions tensorielles plus generales sont necessaires pour couvrir des classes plus larges de systemes de communication faisant intervenir a la fois des modeles de transmission et de canal plus complexes et des methodes de traitement plus efficaces. Cette these traite les problemes de modelisation des systemes multi-antennes, d’egalisation de canal, de separation de signaux et d’estimation parametrique de canal a l’aide d’approches tensorielles. Dans un premier temps, de nouvelles decompositions tensorielles (bloc-PARAFAC avec contraintes et CONFAC) ont ete developpees et etudiees en termes d’identifiabilite. Dans un deuxieme temps, la decomposition bloc-PARAFAC avec contraintes a ete appliquee tout d’abord pour mettre en evidence une modelisation tensorielle unifiee des systemes surechantillonnes, DS-CDMA et OFDM, avec application a l’egalisation multiutilisateur. Puis, cette decomposition a ete utilisee pour modeliser des systemes de transmission MIMO avec etalement spatio-temporel et detection aveugle. La decomposition CONFAC a ensuite ete exploitee pour concevoir un nouveau schema de transmission MIMO/CDMA combinant diversite et multiplexage spatial. Les proprietes d’unicite de cette decomposition ont permis de realiser un traitement aveugle au niveau du recepteur pour la reconstruction du canal et des symboles transmis. Un troisieme volet du travail concerne l’application de la decomposition PARAFAC pour la conception de nouveaux schemas de transmission spatio-temporel-frequentiel pour des systemes MIMO multiporteurs, et pour l’estimation parametrique de canaux multitrajets.
Early orthogeriatric treatment of trauma in the elderly: a systematic review and metaanalysis.

BACKGROUND More than 125,000 hip fractures occur in Germany every year, with a one-year mortality of about 25%. To improve treatment outcomes, models of cooperation between trauma surgery and geriatrics have been developed. Their benefit has not yet been unequivocally demonstrated. METHODS We systematically searched the Medline database and the Cochrane Library for prospective randomized controlled trials in which the treatment of elderly patients with fractures by the trauma surgery service alone was compared with preoperatively initiated collaborative treatment by the trauma surgery and geriatric services ("orthogeriatric" treatment). We investigated three treatment outcome variables--length of hospital stay, in-hospital mortality, and one-year mortality--in a metaanalysis. RESULTS The five trials of hip fracture treatment that met the selection criteria all had relatively small study populations and a high risk of bias. The outcomes with respect to hospital stay differed greatly among trials (I(2): 88.5%), and geriatric intervention was not found to have any statistically significant effect (0.06 days, 95% confidence interval [CI]: -3.74 to 3.62 days). The relative risk of dying in the hospital was 0.66 for orthogeriatric treatment (95% CI: 0.28-1.55, p = 0.34), and the hazard ratio for one-year mortality was 0.79 in favor of orthogeriatric treatment (95% CI: 0.57 to 1.10, p = 0.17). A metaanalysis of functional outcomes was not possible. CONCLUSION Only a few randomized controlled trials of early orthogeriatric treatment have been performed, and these trials are of limited quality. Due to low case numbers, a benefit from interdisciplinary orthogeriatric treatment could not clearly be demonstrated. Further trials are needed.
Stress and Cytokine-elicited Neuroendocrine and Neurotransmitter Sensitization: Implications for Depressive Illness

Stressful events, by their effects on neurotransmitter and neuroendocrine processes, are thought to favor the development or exacerbation of depressive illness. In as much as immunological challenge, may provoke stressor-like neuroendocrine and central neurochemical changes, the view was offered that immune activation essentially acts like a stressor and may contribute to the evolution of affective illness. In this respect, viral and bacterial infections appear to influence behavioral/metabolic (e.g. fever, anorexia, somnolence) and neurotransmitter functioning through the release of cytokines, which act as messengers between the immune system and brain. The present report provides a brief overview of the neurochemical consequences of proinflammatory cytokine treatments, particularly the actions of interleukin (IL)-1 g and tumor necrosis factor- f. As well, synergy with psychogenic and neurogenic stressors are described, as are data showing that cytokines, like stressors, may have time-dependent proactive (sensitization) effects, so that reexposure to the treatments greatly augments hypothalamic-pituitary-adrenal activity, as well as central neurochemical changes. Indeed, the neurotransmitter alterations are not restricted to hypothalamic nuclei, but occur in several extrahypothalamic sites, including various limbic regions. It is suggested that by virtue of these neurochemical changes, cytokines may have both immediate and proactive effects on mood states.
Endothelial Survival After Descemet Membrane Endothelial Keratoplasty: Effect of Surgical Indication and Graft Adherence Status.

IMPORTANCE This study evaluates the longevity of Descemet membrane endothelial keratoplasty (DMEK) grafts in terms of endothelial survival and endothelial failure. OBJECTIVE To determine endothelial survival and its association with the indication for surgery and/or partial graft detachment in DMEK. DESIGN, SETTING, AND PARTICIPANTS Retrospective cross-sectional study of data collected from August 8, 2006, until June 17, 2015, at a tertiary referral center. A total of 352 eyes were evaluated up to 8 years after DMEK for Fuchs endothelial corneal dystrophy (FECD; n = 314), bullous keratopathy (BK; n = 31), and failed previous endothelial graft (n = 7), of which 314 eyes had complete graft attachment and 38 eyes had partial graft detachment (one-third of the graft surface area or less). Endothelial cell density was measured with specular microscopy, and Kaplan-Meier survival estimates were based on eyes with endothelial failure. Endothelial survival was followed up to 8 years after DMEK. MAIN OUTCOMES AND MEASURES Endothelial cell density, endothelial failure, and endothelial survival. RESULTS Endothelial cell density decreased to a mean (SD) of 952 (366) and 771 (321) cells/mm2 at 7 and 8 years postoperatively, respectively. Higher endothelial cell densities were found in eyes with FECD compared with those with BK (estimated mean difference, 261 cells/mm2; 95% CI, 118-404; P = .003) and in eyes with attached grafts compared with those with partially detached grafts (estimated mean difference, 330 cells/mm2; 95% CI, 208-452; P < .001), until 8 years. In 11 eyes (3.1%) that had concomitant ocular pathology, endothelial failure occurred within 4 years after DMEK. The overall graft survival probability was 0.96 at 5 and 8 years (95% CI, 0.94-0.99). At 8 years, better survival rates were found in eyes with FECD than in those with BK (survival probability, 0.97 [95% CI, 0.95-0.99] vs 0.84 [95% CI, 0.70-0.99], respectively); until the same follow-up, survival probabilities in eyes with attached and partially detached grafts were 0.97 (95% CI, 0.95-0.99) and 0.91 (95% CI, 0.82-0.99), respectively. CONCLUSIONS AND RELEVANCE Endothelial decay was higher in eyes with a partial graft detachment than in those with attached grafts and lower in eyes with FECD than in those with BK. Endothelial failure only occurred in eyes with concomitant ocular pathology. These results suggest that eyes with DMEK that have undergone surgery for FECD with a completely attached graft may have an excellent prognosis.
