Riassunto L’articolo esamina l’ipotesi, formulata qualche anno fa da Pilar Lorenzo (2013 e 2016), secondo la quale i Lais de Bretanha circolarono in maniera indipendente e in ordine diverso. Una nuova analisi dei dati positivi non permette di confermare questa teoria. Indipendentemente dall’ordine primitivo delle cantigas ‘bretoni’, è altamente probabile che i Lais e le rispettive rubriche siano state composte in due momenti distinti. In particolare, la redazione delle rubriche potrebbe risalire all’epoca in cui i Lais furono inseriti nell’exemplar dei Canzonieri portoghesi di Colocci e, di conseguenza, l’ultima pericope della rubrica di B1 (Este lais posemos acá porque era o melhor que foi feito) giustificherebbe, non la prima posizione che il testo venne ad assumere nella Laissammlung, bensì la funzione di ‘prologo in versi’ che il compilatore aveva assegnato a B1 nella sua collezione di cantigas. L’articolo, inoltre, aggiunge alcuni elementi che convergono con l’ipotesi - già a suo tempo formulata da Carolina Michaëlis de Vasconcellos - secondo la quale D. Pedro, Conte de Barcelos (e la sua cerchia aristocratica) sarebbe stato il responsabile dell’inserimento dei Lais nell’exemplar e della redazione delle rubriche.

Abstract The paper examines the hypothesis, put forward a few years ago by Pilar Lorenzo Gradín (2013 and 2016), according to which the Lais de Bretanha would have circulated independently and in a different order. A new analysis of the positive data does not confirm this theory. Regardless of the primitive order of the ‘Breton’ cantigas, it is highly probable that the Lais and the associated rubrics were composed at two different times. In particular, the rubrics could be written at the time when the Lais were inserted in the exemplar of the Colocci’s Portuguese Cancioneiros and, consequently, the last sentence of the rubric of B1 (Este lais posemos acá porque era o melhor que foi feito) could justify, not the first position that the text came to assume in the Laissammlung, but the function of “prologue in verse” that the compiler had assigned to B1 in the structure of the collection of cantigas. In addition, the article adds some elements that agree with the hypothesis - already put forward by Carolina Michaëlis de Vasconcellos - according to which D. Pedro, Earl of Barcelos (and his aristocratic circle) was responsible for the insertion of the Lais into the exemplar and the redaction of rubrics.

Abstract Frequently, aggressiveness and violence are used as synonymous. However, these are two complex and different phenomena that scientists and philosophers have studied. In this paper, we make a difference between aggressiveness and violence. Aggressiveness must be considered utilitarian behavior that harms or destroys objects or subjects. Aggressiveness is a primitive way to conduct, and here, we discuss anatomic and functional encephalic systems. This involuntary and instinctive behavior is triggered when the animal is required to hunt a press, defend its territory when young, or compete for a mate for reproductive purposes. The aggressiveness will be violence when it pursues a social, political, economic, or criminal goal. A violent or aggressive act is not distinguished by the outcome but by intentionality. Indeed, a violent action could have the same material consequences as an aggressive act with a different goal. Aggression-violence is a biological phenomenon and the result of culture, societal life, political relations, and current moral conditions. We often tend to simplify the phenomena, and we have discussed aggressiveness-violence, but there are also other phenomena, such as empathy and mirror behavior. Empathy, compassion, and affection should be studied alongside the aggressive-violent process.

ABSTRACT: Neurofibromas are neoplasms derived from nerve bundles and are frequent in humans but not common in animals. This report described the macroscopic, histologic, and immunohistochemistry findings of an orbitofacial neurofibroma in a sow. The sow presented left eyelids with marked expansion, associated with severe ectropion and reddening of both conjunctival mucosae. The mass on the cutting surface was homogeneous, with a light tan, and shiny, measuring 9.0 x 7.0 x 7.0 cm in width, compressing the eyeball. Microscopically, there was paucicellular neoplastic proliferation of elongated cells amid the accentuated myxoid matrix. There were multifocal areas where well-differentiated nervous fascicles and skeletal musculature were seen. Neoplastic cells were immunostained positive for GFAP, neurofilament, S-100, Sox-10, and vimentin. Cytokeratin showed immunolabeling around primitive nerve bundles and desmin around neoformed vessels and muscle bundles within the tumor. Orbitopalpebral and orbitofacial neurofibroma, despite being common in humans, have not been described in domestic pigs and should be considered as a differential diagnosis in eyelid tumors in pigs.

RESUMO: Neurofibromas são neoplasias derivadas dos feixes nervosos e são frequentes em humanos, mas incomuns em espécies animais domésticos. Esse relato tem como objetivo descrever os achados macroscópicos, histológicos e imuno-histoquímicos de um neurofibroma orbitofacial em uma matriz suína. O animal apresentava as pálpebras esquerdas acentuadamente expandidas, associada a severo ectrópio e avermelhamento de ambas as mucosas conjuntivais. A tumoração palpebral, na superfície de corte, era homogênea, levemente acastanhada e brilhante, medindo 9,0 x 7,0 x 7,0 cm, e comprimia o globo ocular. Microscopicamente foi observada uma proliferação neoplásica pobremente celular de células alongadas no meio de uma acentuada quantidade de matriz mixoide. Havia áreas intratumorias multifocais onde fascículos nervosos bem diferenciados e musculatura esquelética foram observados. As células neoplásicas foram positivas na imuno-histoquímica para GFAP, neurofilamento, S-100, Sox-10 e vimentina. Citoqueratina mostrou uma imunomarcação ao redor de feixes nervosos primitivos e desmina ao redor de vasos neoformados e feixes musculares dentro do tumor. O neurofibroma orbitofacial, apesar de comum em humanos, nunca foi descrito em suínos domésticos e deve ser considerado um diagnóstico diferencial para neoplasias palpebrais em suínos.

Abstract: The theme of repentance is eternal for Christians. Almost all the Holy Fathers touched upon it with necessity and called to resort to this miraculous preparation given by the Church. It also runs like a red thread through the work of Pratum by John Moschus. The purpose of this study is to analyze the work of Pratum by John Moschus, which touches upon the theme of repentance and the main aspects of asceticism. The paper aims to identify the main characteristics of monastic life associated with ascetic practices of primitive monasticism described in the work. The study focuses on the addressees of the work, namely the monks for whom the work was written, and the topics about ascetic practices, the importance and necessity of repentance and the action of divine grace in human life. The study intends to ensure that these themes and practices are inherited by other generations and do not lose their relevance. Abstract Christians Church Moschus asceticism written relevance

ABSTRACT Twin reversed arterial perfusion (TRAP) sequence is a rare complication of monochorionic twinning whereby a donor twin perfuses an acardiac twin via aberrant vascular anastomoses. The resulting paradoxical retrograde blood flow supplying the acardiac twin is oxygen-poor, leading to some of the most severe malformations encountered in humans. Though the first descriptions of acardiac twins date back to at least the 16th century, the pathophysiologic processes which underpin the development of TRAP sequence are still being elucidated. Theories on the pathogenesis of TRAP sequence include deficiencies intrinsic to the embryo and primary abnormalities of the placental vasculature. Autopsy studies continue to provide clues to the underlying pathogenesis of TRAP sequence, and the characterization of the spectrum of manifestations that can be observed in acardiac twins. Herein, we present the clinical, autopsy, and molecular findings in a unique case of TRAP sequence. Novel findings include a primitive cloaca-like structure and chromosomal aberrations involving 6q11.1 and 15q25.1.

Immature hematopoietic progenitors are a constant source for renewal of hemocyte populations and the basic component of the tissue and cell repair apparatus. A unique property of these cells of internalizing extracellular double-stranded DNA has been previously shown. The leukostimulatory effect demonstrated in our pioneering studies was considered to be due to the feature of this cell. In the present research, we have analyzed the effects of DNA genome reconstructor preparation (DNAgr), DNAmix, and human recombinant angiogenin on both hematopoietic stem cells and multipotent progenitors. Treatment with bone marrow cells of experimental mice with these preparations stimulates colony formation by hematopoietic stem cells and proliferation of multipotent descendants. The main lineage responsible for this is the granulocyte-macrophage hematopoietic lineage. Using fluorescent microscopy as well as FACS assay, co-localization of primitive c-Kit- and Sca-1-positive progenitors and the TAMRA-labeled double-stranded DNA has been shown. Human recombinant angiogenin was used as a reference agent. Cells with specific markers were quantified in intact bone marrow and colonies grown in the presence of inducers. Quantitative analysis revealed that a total of 14,000 fragment copies of 500 bp, which is 0.2% of the haploid genome, can be delivered into early progenitors. Extracellular double-stranded DNA fragments stimulated the colony formation in early hematopoietic progenitors from the bone marrow, which assumed their effect on cells in G0. The observed number of Sca1+/c-Kit+ cells in colonies testifies to the possibility of both symmetrical and asymmetrical division of the initial hematopoietic stem cell and its progeny. apparatus doublestranded double stranded shown research DNAgr, DNAgr , (DNAgr) DNAmix descendants granulocytemacrophage granulocyte macrophage assay colocalization co localization cKit c Kit c-Kit Sca1positive Scapositive Sca 1 positive TAMRAlabeled TAMRA labeled agent inducers 14000 14 000 14,00 50 bp 02 0 2 0.2 G0 G Sca1+/cKit+ Sca1cKit ScacKit Sca1+/c Kit+ Sca1 Sca1+/c-Kit progeny (DNAgr 1400 00 14,0 5 0.

ABSTRACT A case of peripheral primitive neuroectodermal tumor in the cervical region of a canine is described. The patient was a canine, male, five years old, large size, with acute neurological clinical signs, severe neck pain and tetraplegia. On computed tomography, an oval-shaped mass located dorsally to cervical vertebrae C4 to C7 was observed, with infiltration over the spinal cord between vertebrae C4 and C5, discreetly widening the dorsal intervertebral foramina of the cervical vertebrae and compressing the dorsal portion of the spinal cord of this segment. Under microscopy, the neoplastic cells were small, irregular in shape and with scarce cytoplasm. Immunoreactivity for vimentin, which can only be expressed in PTNEs tumors, was decisive for diagnostic confirmation. Additionally, the positivity of the S-100 protein, which is expressed in neuroectodermal cells mainly of the neural crest cells, reinforced the classification as PTNE, and the negativity in the expression for glial fibrillary acidic protein (GFAP) ruled out the presence of small cell glioma of the central nervous system. Based on the clinical history, imaging exams, cellular morphology and mainly on immunohistochemical staining, the diagnosis of primitive neuroectodermal tumor (PTNE) with infiltration and compression of the spinal cord in the cervical region of the dog was confirmed, considered uncommon in this species. described male old size signs tetraplegia tomography ovalshaped oval shaped C observed C5 segment microscopy cytoplasm vimentin tumors confirmation Additionally S100 S 100 S-10 PTNE GFAP (GFAP system history exams staining (PTNE confirmed species S10 10 S-1 S1 1 S-

RESUMO Descreve-se um caso de tumor neuroectodérmico primitivo periférico na região cervical de um canino. O paciente em questão era um canino, macho, de cinco anos, porte grande, com sinais clínicos neurológicos agudos, cervicoalgia severa e tetraplegia. Na tomografia computadorizada, foi observada uma massa de aspecto ovalado localizada dorsalmente às vértebras cervicais C4 a C7, com infiltração sobre a medula espinhal entre as vértebras C4 e C5, alargando discretamente os forames intervertebrais dorsais das vértebras cervicais e comprimindo a porção dorsal da medula espinhal deste segmento. Na microscopia, as células neoplásicas eram pequenas, de formato irregular e citoplasma escasso. A imunorreatividade para vimentina, que só pode ser expressa em tumores PTNEs, foi determinante para a confirmação diagnóstica. Adicionalmente, a positividade da proteína S-100, que é expressa em células neuroectodérmicas principalmente das células da crista neural, reforçou a classificação como PTNE, e a negatividade na expressão para proteína ácida fibrilar glial (GFAP) descartou a presença de glioma de pequenas células do sistema nervoso central. Com base no histórico clínico, em exames de imagem, na morfologia celular e principalmente na coloração imuno-histoquímica, confirmou-se o diagnóstico de tumor neuroectodérmico primitivo (PTNE) com infiltração e compressão na medula espinhal na região cervical do cão, considerado incomum nessa espécie.

ABSTRACT. This review is based on a conference presented in June 2023. Its main objective is to explain the cognitive differences between humans and non-human primates (NHPs) focusing on characteristics of their brains. It is based on the opinion of a clinical neurologist and does not intend to go beyond an overview of this complex topic. As language is the main characteristic differentiating humans from NHPs, this review is targeted at their brain networks related to language. NHPs have rudimentary forms of language, including primitive lexical/semantic signs. Humans have a much broader lexical/semantic repertory, but syntax is the most important characteristic, which is probably unique to Homo sapiens. Angular gyrus, Broca's area, temporopolar areas, and arcuate fascicle, are much more developed in humans. These differences may explain why NHPs did not develop a similar language to ours. Language had a profound influence on all other higher nervous activities.

RESUMO Esta revisão baseia-se numa conferência apresentada em junho de 2023. O seu principal objetivo é explicar as diferenças cognitivas entre humanos e primatas não humanos (PNH) com base nas características dos seus cérebros. Baseia se na opinião de um neurologista clínico e não pretende ir além de uma visão geral deste tema complexo. Como a linguagem é a principal característica que diferencia os humanos dos PNH, esta revisão concentra-se nas redes cerebrais relacionadas à linguagem. Os PNH têm formas rudimentares de linguagem, incluindo sinais lexicais/semânticos primitivos. Os humanos têm um repertório léxico/semântico muito mais amplo, mas a sintaxe é a característica mais importante e única do Homo sapiens. O giro angular, a área de Broca, as áreas temporopolares e o fascículo arqueado são muito mais desenvolvidos em humanos. Essas diferenças podem explicar por que os PNH não desenvolveram uma linguagem semelhante à nossa. A linguagem teve influência profunda em todas as outras atividades nervosas superiores. baseiase baseia 2023 (PNH cérebros complexo concentrase concentra lexicaissemânticos lexicais semânticos primitivos léxicosemântico léxico semântico amplo sapiens angular Broca nossa superiores 202 20 2

Aim To report a case of non-neural granular cell tumor (NN-GCT), an uncommon neoplasm, with only six studies worldwide describing cases involving the oral cavity. Methods A 26-year-old male patient with an erythematous, firm, polypoid nodule in the floor of the mouth that exhibited areas of ulceration and mild bleeding to the touch. A biopsy was performed to aid in the diagnosis. Results Based on the histopathological and immunohistochemical results (vimentin +, CD68 +, S100 -), the diagnosis was compatible with S100-negative (primitive polypoid non-neural) granular cell tumor. No recurrence was observed over two years of follow-up. Conclusion The diagnosis of NN-GCT is extremely challenging because this tumor shares histological and immunophenotypic features with many benign and malignant tumors. Although oral NN-GCT may exhibit unusual and atypical histological features, it has an indolent behavior. Thus, until more cases of oral involvement are reported, complete resection and close follow-up are recommended. nonneural non neural NNGCT, NNGCT NN GCT , (NN-GCT) neoplasm cavity 26yearold yearold 26 year old erythematous firm touch vimentin + CD CD6 S S10 -) S100negative Snegative negative primitive followup. followup follow up. up tumors behavior Thus reported recommended (NN-GCT 2 S1 -

ABSTRACT Management of Quilombola systems are primitive agricultural systems based on the ancestral knowledge of Afro-Brazilian enslaved people. Here, the aim was to understand the impact of these primitive farming methods on the distribution of available nitrogen (N) forms in the soil profile of two Brazilian Cerrado phytophysiognomies. The soil was sampled in Cerradão (high Cerrado) and Cerrado Stricto sensu (low Cerrado) at six soil depths (0-10, 10-20, 20-30, 30-40, 40-50, and 50-60 cm). The following management systems were considered: pasture (PP1 and PP2), maize cultivation (M1 and M2), citrus-cassava intercropping (T1), and citrus monoculture (T2). In addition, the soil was sampled in the native area of Cerradão (NC1) and Cerrado Stricto sensu (NC2). Three N forms were determined: i) available nitrogen (Av-N), ii) ammonium (NH4+-N) and iii) nitrate (NO3–-N) contents. The Av-N content decreased with increasing soil depth only in NC1 and NC2. The NO3–-N content was similar at all soil depths for maize and pasture, while the content decreased at soil depth for NC1, NC2, and T1. NH4+-N was similar in M2 and PP2, but it increased in T2, ranging from 6.17 mg kg–1 to 17.54 mg kg–1. Overall, the dynamics of available N forms varied according to the Cerrado phytophysiognomy and the management systems and NO3–-N was the most constant N form in the soil profile. Therefore, although the management of Quilombola systems is less intensive, they negatively affect the dynamics and N availability, mainly where management is less conservative, that is, in maize and citrus monocultures.

Resumen La región del semiárido brasileño es el nuevo destino del capital global en energías renovables, frente a la crisis ambiental. Este hecho trae como consecuencia la expansión de las bases de acumulación de capital: extracción de plusvalía de la fuerza de trabajo, acaparamiento de tierras de campesinos y concentración de tierras. Para discutir esa problemática, los objetivos del presente texto son: a) señalar las nuevas particularidades de la cuestión agraria frente la expansión de parques eólicos; b) analizar el proceso de desposesión de tierras de los agricultores; y c) presentar la relación de los contratos de arrendamiento con la renta de la tierra. Para eso, realizamos una revisión de literatura respecto a los temas de privatización de los bienes comunes, en particular de las tierras para la producción de energía eólica, buscando explicar como la privatización de bienes comunes, particularmente la fuerza de los vientos, implica estrategias legales de reducción de derechos y de servicios básicos a derechos exclusivos de propiedad privada. La “acumulación por desposesión”, concepto formulado porDavid Harley (2011) y aplicado porMariana Traldi (2019) en el análisis de la expansión de la energía eólica en Brasil, implica apropiación por el capital de extensas áreas con el pretexto de garantizar el “desarrollo sostenible”, el enfrentamiento a la “crisis hídrica” o una “agenda verde”.

Abstract The leasing of land for wind power production is the subject analyzed in this work, precisely the control exercised by multinationals of the exploration rights from peasants’ lands. Taking in consideration that the semi-arid region of Brazil is the new destination for the global capital in renewable energies, given the environmental crises, the research presents its relevance for the study of wind farms. The main problem is that this expansion copies the foundations of the primitive accumulation of capital: extraction of surplus value from the labor force, land grabbing of peasants and land concentration. The goals go from pointing out the new singularities of the agrarian situation in face of the expansion of wind farms to analyze the process of dispossession of land from farmers and to show the link between lease contracts and land profit. The theses ofDavid Harvey (2011) andMariana Traldi (2019), in which they aim to explain how the privatization of common goods, particularly of the wind force, involves the use of legal strategies that reduce rights and basic services on the common good to exclusive rights of Private propriety, were used. “Accumulation by dispossession,” for Harvey, and its “green” version, for Traldi, imply the appropriation by capital of large areas of land on the pretext of ensuring “sustainable development,” the fight against the “water crisis” or a “green agenda.” Therefore, we investigate the hypothesis that the implementation of wind farms in Brazil involves the storage of land under the control of the economic exploitation rights of the farmers over their land and that this is included in a new movement of land reconcentration. work lands semiarid semi arid energies crises force concentration profit 2011 (2011 2019, 2019 , (2019) goods propriety used Accumulation dispossession, green version sustainable development, development water crisis agenda. agenda Therefore reconcentration 201 (201 (2019 20 (20 2 (2 (

ABSTRACT Triply periodic minimal surface (TPMS) structures are commonly used for lightweight and energy-absorption applications. TPMS structures have a high porosity and are prone to the pinch-off phenomenon. In this study, we designed primitive and Schoen I-graph-wrapped package (I-WP) structures with different porosities. An optimized design function was introduced to obtain a high-porosity P-I structure, which was less prone to pinch off. The mechanical properties of the structures with different porosities achieved using selective laser sintering technology were investigated. Results showed that the porosities of primitive, I-WP, and P-I structures exhibited different correlations with the constant t. The elastic modulus and yield strength of all three structures decreased with porosity. For the same porosity, the compressive strength and elastic modulus of the P-I porous structure exceeded those of the primitive and I-WP porous structures. Additionally, the primitive porous structure was predominantly in the stretching deformation mode, whereas the I-WP and P-I structures were mostly in the stretching and bending deformation modes. The P-I porous structure showed better energy-absorption properties than the primitive and I-WP structures. This study enriched extremely small-surface porous structures and provided a relevant basis for their application in engineering fields.

ABSTRACT Ewing sarcoma (ES) is a highly malignant and aggressive small round-cell tumor originating from primitive neuroepithelium and mesenchymal stem cells. It is usually seen in children and adolescents with a male predilection and a preponderance to occur in long bones. Although skeletal/soft tissue ES is encountered in clinical practice, primary ES of the genital tract, particularly bilateral primary ovarian ES, is highly uncommon, with only a handful of cases reported worldwide. Ovarian ES is occasionally reported to involve para-aortic and pelvic lymph nodes in advanced stages. Still, cervical lymph node metastasis from ovarian ES is an infrequent clinical occurrence and, when present, indicates a worse prognosis. Here, we present an intriguing case of bilateral peripheral primary ovarian ES in an adult female, recurring as metastasis in the left submandibular lymph node. This case underlines the importance of keeping metastasis from ES as a possible differential while diagnosing metastatic small round cell tumors in peripheral lymph nodes. It also highlights the usefulness of a minimally invasive diagnostic modality of fine needle aspiration cytology and cell block preparation with applied ancillary techniques of immunohistochemistry and confirmatory molecular testing by fluorescence in-situ hybridization (FISH), for an accurate and quick diagnosis of such entities. The cytological diagnosis of our patient helped in the prompt and early initiation of chemotherapy without requiring any invasive procedure.

Vein of Galen aneurysmal malformation (VGAM) is a rare congenital malformation characterised by arteriovenous fistulas between primitive choroidal arteries and the median prosencephalic vein, the embryonic precursor to the vein of Galen. Endovascular techniques have changed the management of these patients with improved prognosis. An eight-month-old with VGAM managed by endovascular embolisation using ethylene vinyl alcohol copolymer (EVOH) developed a chemical abscess - a rare complication. It was managed conservatively and showed promising clinical outcome. CONTRIBUTION: Chemical abscesses following EVOH embolisation are scarce - with imaging differentials, which include brain abscess and onyx granuloma. Knowledge and successful identification of this entity are essential as its management as prognoses differ. Chemical abscess is managed conservatively and has a good prognosis.
