Presencia y función de los saberes psi en la “Edad de oro” de la literatura de Ciencia Ficción chilena (1959- 1973)

Indexación: Scopus.The works of Hugo Correa, María Elena Aldunate and Antonio Montero have been recognized as crucial contributions in the development of Chilean Science Fiction, giving rise to the so-called “Golden Age” of the genre (1959-1973). Despite that their novels and stories problematize the sociocultural transformations of their time, their writings also incorporated conceptual references from psychology, psychiatry and psychoanalysis -psi knowledge- in the configuration of the plot and the features of its characters. The present article seeks to identify the presence of concepts coming from the field of psi knowledge in the work of these three authors and analyze the literary effects they had in the construction of the arguments and the characters of their stories. In this way, the singularity of the works of this period could not be reduced to their social sensitivity or the use of technological or scientific categories. In addition to interpreting socio-cultural conflicts, Chilean Science Fiction of that decade showed a marked interest in the dilemmas of the subjectivity of its time by addressing the problems pertaining mental, intelligence, perception, psychological self, anxiety, and alterity through the incorporation of psi knowledge in the process of literary creation.https://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0071-17132020000100045&lng=en&nrm=iso&tlng=e

Valor preditivo da punção liquórica (tap test) na hidrocefalia de pressão normal

Eighteen patients (mean age of 66.5 years) with normal pressure hydrocephalus (NPH) underwent a ventriculo-peritoneal shunt surgery. Prior to operation a cerebrospinal fluid tap-test (CSF-TT) was performed with measurements of gait pattern and psychometric functions (memory, visuo-motor speed and visuo-constructive skills) before and after the removal of 50 ml CSFby lumbar puncture (LP). Fifteen patients improved and 3 were unchanged after surgery. Short duration of disease, gait disturbance preceding mental deterioration, wide temporal horns and small sulci on CT-scan were associated with good outcome after shunting. There was a good correlation between the results of CSF-TT and shunt surgery (X² = 4,11 ,phi = 0.48, p < 0.05), with gait test showing highest correlation (r = 0.99, p = 0.01). In conclusion, this version of CSF-TT proved to be an effective test to predict improvement after shunting in patients with NPH.Este estudo visa melhorar o valor diagnóstico e preditivo da punção liquórica (tap test, TT) na hidrocefalia de pressão normal (HPN), particularmente nos casos em que os dados clinicos e de neuroimagem são inconclusivos e não permitem uma decisão cirúrgica segura. Dezoito pacientes (média de idade = 66.5 anos) com HPN foram submetidos a derivação (shunt) ventriculo-peritoneal. O TT era realizado antes da cirurgia, consistindo na análise quantitativa da marcha e funções cognitivas (memória, rapidez perceptivo-motora e habilidade vísuo-construtiva) antes e depois da retirada de 50 ml de liquor via punção lombar. Quinze pacientes melhoraram e 3 permaneceram inalterados após a cirurgia. Curta duração da doença, distúrbio da marcha precedendo a deterioração mental, dilatação dos cornos temporais e apagamento (ou redução) dos sulcos corticais na tomografia computadorizada cerebral estavam associados a bons resultados pós-operatórios. Houve boa correlação entre os resultados do TT e os do shunt (X² = 4.11, phi = 0.48, p < 0.05), principalmente no teste da marcha (r = 0.99, p = 0.01). Esta versão do TT liquórico mostrou-se efetiva na prediçâo da melhora pós-operatória em pacientes com HPN.17918

CP-odd static electromagnetic properties of the W gauge boson and the t quark via the anomalous tbW coupling

In the framework of the electroweak chiral Lagrangian, the one-loop induced effects of the anomalous $tbW$ coupling, which includes both left- and right-handed complex components, on the static electromagnetic properties of the $W$ boson and the $t$ quark are studied. The attention is focused mainly on the CP-violating electromagnetic properties. It is found that the $tbW$ anomalous coupling can induce both CP-violating moments of the $W$ boson, namely, its electric dipole ($\tilde{\mu}_W$) and magnetic quadrupole ($\tilde{Q}_W$) moments. As far as the $t$ quark is concerned, a potentially large electric dipole moment $(d_t)$ can arise due to the anomalous $tbW$ coupling. The most recent bounds on the left- and right-handed parameters from $B$ meson physics lead to the following estimates $\tilde{\mu}_W ~ 10^{-23}-10^{-22}$ e-cm and $\tilde{Q}_W~ 10^{-38}-10^{-37}$ e-cm$^2$, which are 7 and 14 orders of magnitude larger than the standard model (SM) predictions, whereas $d_t$ may be as large as $10^{-22}$ e-cm, which is about 8 orders of magnitude larger than its SM counterpart.Comment: This paper has been merged with hep-ph/0612171 for publication in Physical Review

Congenital Destructive Hemispheric Lesions And Epilepsy: Clinical Features And Relevance Of Associated Hippocampal Atrophy.

We studied the clinical, EEG and MRI findings in 19 patients with epilepsy secondary to congenital destructive hemispheric insults. Patients were divided in two groups: 10 with cystic lesions (group 1), and 9 with atrophic lesions (group 2). Seizure and EEG features, as well as developmental sequelae were similar between the two groups, except for the finding that patients of group 2 more commonly presented seizures with more than one semiological type. MRI showed hyperintense T2 signal extending beyond the lesion in almost all patients of both groups, and it was more diffuse in group 2. Associated hippocampal atrophy (HA) was observed in 70% of group 1 patients and 77.7% of group 2, and it was not correlated with duration of epilepsy or seizure frequency. There was a good concordance between HA and electroclinical localization. The high prevalence of associated HA in both groups suggests a common pathogenesis with the more obvious lesion. Our findings indicate that in some of these patients with extensive destructive lesions, there may be a more circumscribed epileptogenic area, particularly in those with cystic lesions and HA, leading to a potential rationale for effective surgical treatment.58990-100

De Novo Psychogenic Seizures After Epilepsy Surgery: Case Report.

The occurrence of de novo psychogenic seizures after epilepsy surgery is rare, and is estimated in 1.8% to 3.6%. Seizures after epilepsy surgery should be carefully evaluated, and de novo psychogenic seizures should be considered especially when there is a change in the ictal semiology. We report a patient with de novo psychogenic seizures after anterior temporal lobe removal for refractory temporal lobe epilepsy. Once psychogenic seizures were diagnosed and psychiatric treatment was started, seizures stopped.58535-
