História e memória da Revolu??o Farroupilha: breve genealogia do mito
Zalla, Jocelito;Menegat, Carla;
Revista Brasileira de História , 2011, DOI: 10.1590/S0102-01882011000200005
Abstract: the aim of this paper is to present a panorama of manifestations related to the farroupilha revolution, from the event itself to its consolidation as the founding myth of regional identity in rio grande do sul. debating important moments in this process, such as the refraction of memory in relation to the event, its political appropriation by the republican project, its rehabilitation in historical memory, and its ritualization in gaúcho traditionalism, it is proposed to analytically reconstitute the establishment of the fact as a symbolically cohesive and multiple heritage, sufficiently elastic to guide internal conflicts and tensions between the state and the center of brazil.
The amygdala and the relevance detection theory of autism: an evolutionary perspective
Tiziana Zalla,Marco Sperduti
Frontiers in Human Neuroscience , 2013, DOI: 10.3389/fnhum.2013.00894
Abstract: In the last few decades there has been increasing interest in the role of the amygdala in psychiatric disorders and, in particular, in its contribution to the socio-emotional impairments in autism spectrum disorders (ASDs). Given that the amygdala is a component structure of the “social brain,” several theoretical explanations compatible with amygdala dysfunction have been proposed to account for socio-emotional impairments in ASDs, including abnormal eye contact, gaze monitoring, face processing, mental state understanding, and empathy. Nevertheless, many theoretical accounts, based on the Amygdala Theory of Autism, fail to elucidate the complex pattern of impairments observed in this population, which extends beyond the social domain. As posited by the Relevance Detector theory (Sander et al., 2003), the human amygdala is a critical component of a brain circuit involved in the appraisal of self-relevant events that include, but are not restricted to, social stimuli. Here, we propose that the behavioral and social–emotional features of ASDs may be better understood in terms of a disruption in a “Relevance Detector Network” affecting the processing of stimuli that are relevant for the organism’s self-regulating functions. In the present review, we will first summarize the main literature supporting the involvement of the amygdala in socio-emotional disturbances in ASDs. Next, we will present a revised version of the Amygdala Relevance Detector hypothesis and we will show that this theoretical framework can provide a better understanding of the heterogeneity of the impairments and symptomatology of ASDs. Finally, we will discuss some predictions of our model, and suggest new directions in the investigation of the role of the amygdala within the more generally disrupted cortical connectivity framework as a model of neural organization of the autistic brain.
On the evolution of phenomenal consciousness
Jean-Louis Dessalles,Tiziana Zalla
Quantitative Biology , 2011,
Abstract: A number of concepts are included in the term 'consciousness'. We choose to concentrate here on phenomenal consciousness, the process through which we are able to experience aspects of our environment or of our physical state. We probably share this aspect of consciousness with many animals which, like us, feel pain or pleasure and experience colours, sounds, flavours, etc. Since phenomenal consciousness is a feature of some living species, we should be able to account for it in terms of natural selection. Does it have an adaptive function, or is it an epiphenomenon ? We shall give arguments to reject the second alternative. We propose that phenomenal properties of consciousness are involved in a labelling process that allows us to discriminate and to evaluate mental representations. We also discuss to what extent consciousness as such has been selected for this labelling function.

Abstract: Canine babesiosis caused by tick-borne organisms of the genus Babesia, is one of the most significant disease worldwide. The aims of this study were to determine the hematological changes in six dogs naturally infected with Babesia canis. The hematological evaluation included Hemoglobin (Hb), Red Blood Cell (RBC), Platelet, Packet Cell Volume (PCV), Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin Concentration (MCHC) and Reticulocyte counts. They were estimated using an autonomic hematologic analyzer. The animal had hypocytic hypochromic anemia and 20% of the cases had a packed cell volume (PCV) less of 24%. All the animal had thrombocytopenia and platelets counts was lower than 50x103 cell/ μl The results of this study show that Babesia infection in dogs caused anemia and thrombocytopenia.

Although the prognosis of early gastric cancer (EGC) is considered to be satisfactory, some patients experience tumor relapse after curative surgery. Both pathogenesis and risk factors of recurrence remain unclear. We describe a case report of a 49-year-old male who underwent subtotal gastric resection D2A for angular gastric cancer. Histological examination revealed gastric adenocarcinoma with low grade of differentiation and colloid areas, intramucosal, and absence of neoplastic proliferation in the surgical margins, in omental stroma and in the six examined lymph nodes (pT1, pN0). 11 years later, the same patient underwent D2 total gastrectomy for gastric cancer in the remnant stomach. New histological examination revealed again gastric adenocarcinoma, intramucosal, medium degree of differentiation, no documentable neoplastic proliferation within the limits of surgical resection, in the thirty-three examined lymph nodes and in the omentum (pT1, pN0).

Abstract: Memory for action is enhanced if individuals are allowed to perform the corresponding movements, compared to when they simply listen to them (enactment effect). Previous studies have shown that individuals with Autism Spectrum Disorders (ASD) have difficulties with processes involving the self, such as autobiographical memories and self performed actions. The present study aimed at assessing memory for action in Asperger Syndrome (AS). We investigated whether adults with AS would benefit from the enactment effect when recalling a list of previously performed items vs. items that were only visually and verbally experienced through three experimental tasks (Free Recall, Old/New Recognition and Source Memory). The results showed that while performance on Recognition and Source Memory tasks was preserved in individuals with AS, the enactment effect for self-performed actions was not consistently present, as revealed by the lower number of performed actions being recalled on the Free Recall test, as compared to adults with typical development. Subtle difficulties in encoding specific motor and proprioceptive signals during action execution in individuals with AS might affect retrieval of relevant personal episodic information. These disturbances might be associated to an impaired action monitoring system.

Abstract: Diabetic animals induced by alloxan show severe hyperglycemia and intense catabolism characterized by the absence of insulin. Therefore, the objective of this study is to assess whether the alloxan 6CH, is able to reverse or mitigate the changes promoted by diabetes mellitus, as well as assess the effects of thymulin. In biological tests male Wistar rats were used induced to experimental diabetes by the administration of alloxan (iv 42 mg / kg). The sample comprised four groups (n = 4): G1 ¢a a€ control without the induction of diabetes, G2 - diabetic without treatment, G3 - diabetic treated with thymulin 12CH and G4 - treated with alloxan 6CH. The data were statistically analyzed by ANOVA followed by Tukey-Kramer test (p < 0.05). After treatment for 40 days slight decrease of glucose in animals treated with alloxan (502 ± 28) mg/dl and thymulin (500 ± 10) mg/dl was observed compared with untreated animals (563 ± 23)mg/dl. Remained unchanged feed intake and water, however, significant decrease of body weight in diabetic group (96 ± 21)g was observed compared to animals treated with alloxan (27 ± 23)g and thymulin (20 ± 16)g, fact not observed when the last two groups are compared with the control (5.1 ± 3.9)g. Significant reduction in the percentage of lymphocytes in diabetic animals (44.8 ± 2.4)% and increase in the group treated with thymulin (12CH) (83.3 ± 4.5)% was checked, when compared to the others. Animals treated with alloxan and thymulin showed clinical improvement. Based on these findings it is concluded that alloxan and thymulin improve the general state of the animal, and suggest inhibition of strong catabolism observed in diabetic animals without treatment.

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0095568
Abstract: Social and communication impairments are part of the essential diagnostic criteria used to define Autism Spectrum Disorders (ASDs). Difficulties in appreciating non-literal speech, such as irony in ASDs have been explained as due to impairments in social understanding and in recognizing the speaker’s communicative intention. It has been shown that social-interactional factors, such as a listener’s beliefs about the speaker’s attitudinal propensities (e.g., a tendency to use sarcasm, to be mocking, less sincere and more prone to criticism), as conveyed by an occupational stereotype, do influence a listener’s interpretation of potentially ironic remarks. We investigate the effect of occupational stereotype on irony detection in adults with High Functioning Autism or Asperger Syndrome (HFA/AS) and a comparison group of typically developed adults. We used a series of verbally presented stories containing ironic or literal utterances produced by a speaker having either a “sarcastic” or a “non-sarcastic” occupation. Although individuals with HFA/AS were able to recognize ironic intent and occupational stereotypes when the latter are made salient, stereotype information enhanced irony detection and modulated its social meaning (i.e., mockery and politeness) only in comparison participants. We concluded that when stereotype knowledge is not made salient, it does not automatically affect pragmatic communicative processes in individuals with HFA/AS.
