We report a facile hydrothermal method for the synthesis of niobium pentoxide (Nb2O5) under two different temperatures, 120 °C (Nb2O5-120) and 150 °C (Nb2O5-150). The obtained materials were characterized by structural, optical and morphological techniques. Also, the photocatalytic properties of the Nb2O5 samples were evaluated in two reactions under ultraviolet (UVC) irradiation: degradation of methylene blue (MB) and indigo carmine (IC) dyes; and esterification of free fatty acids (FFA) present in waste cooking oil (WCO). The Nb2O5 was formed at different temperatures of synthesis, and the increase in temperature did not cause significant changes in the structural and optical characteristics, but resulted in an increased surface area of the synthesized materials. Both synthesized materials showed excellent efficiency for dye photodegradation. The sample Nb2O5-150 presented the best performance for the MB photodegradation, with almost 85% of the removal efficiency. In this case, the adsorption of MB molecules on the surface of the material was high due to the favorable electrostatic interaction and also because of its high surface area. For the IC photodegradation, the adsorption was insignificant, and both samples presented approximately 100% of the removal efficiency. These materials were also promising for the reduction of free fat acids in waste oil by photoesterification. NbO Nb O (Nb2O5 12 C Nb2O5120 (Nb2O5-120 15 Nb2O5150. Nb2O5150 .

ABSTRACT We present the case of a 37-year-old woman who underwent bilateral penetrating keratoplasty for congenital hereditary endothelial dystrophy at the age of 10 years. Over the subsequent 27 years, the patient’s vision slowly deteriorated. Our examination revealed decompensation of the right corneal graft. We addressed this with regraft surgery. We then learned that the patient had been suffering from progressive hearing loss since adolescence. Tonal audiometry revealed hearing per ceptive deafness of 25 dB, which was more prominent in the left ear. Because the patterns of progressive sensorineural hearing loss and congenital hereditary endothelial dystrophy have both been linked to the same gene, slc4a11, we tested our patient for mutations in this gene. The test was positive for a heterozygous slc4a11 gene fifth exon mutation on chromosome 20p13-p12, which causes a frameshift. A combined clinical and genetic evaluation confirmed a diagnosis of Harboyan syndrome. After the genetic diagnosis of the disease, she was evaluated for the need for a hearing aid due to her hearing loss. The patient was also informed about genetic counseling. 37yearold yearold 37 year old 1 years 2 patients s deteriorated graft surgery adolescence dB ear slca slc slc4a1 20p13p12, 20p13p12 pp 20p13 p12, p12 p 20p13-p12 frameshift syndrome disease counseling 3 slc4a 20p13p1 20p1 p1 20p13-p1 20p13p 20p 20p13-p

ABSTRACT Optic neuritis is an important cause of unilateral and acute visual loss in young adults, but other differential diagnoses should be considered, especially when the disease has an atypical presentation. This report presents the case of a young woman with reduced visual acuity in her right eye, associated with optic disc edema and a relative afferent pupillary defect, that was initially misdiagnosed as optic neuritis and subsequently found to have paracentral acute middle maculopathy, possibly secondary to subtle impending central retinal vein occlusion. This case emphasizes the need to remember that retinal vascular diseases can occasionally mimic optic neuritis. Detailed anamnesis and ophthalmic examination can avoid unnecessary interventions. adults considered presentation eye defect maculopathy occlusion interventions

ABSTRACT Langerhans cell histiocytosis comprises a heterogeneous range of clinical manifestations secondary to clonal proliferation of histiocytes, characterized by the accumulation of these cells in various organs and tissues. The ophthalmological component commonly involved is the orbit. Herein, we report a rare case of Langerhans cell histiocytosis with eyelid involvement, which resulted in severe ocular surface complications, which subsequently significantly impacted the patient’s quality of life. This case report highlights the fact that despite being rare, Langerhans cell histiocytosis should be included in the differential diagnosis of eyelid lesions. Furthermore, a multidisciplinary approach with a systemic overview is crucial for managing the ocular complications. histiocytes tissues orbit Herein involvement complications patients patient s life lesions Furthermore

ABSTRACT Aging and face sagging have many causes, and various techniques are used for treatment, including noninvasive procedures, such as focused ultrasound, which uses the principle of collagen regeneration by coagulative necrosis of the dermis layers using radiofrequency, but this procedure has complications. We reported a case of a 54-year-old female patient who complained of poor visual acuity in her right eye three days after a focused ultrasound facial aesthetic procedure, with the best visual acuity of 20/60. Biomicroscopy of the right eye revealed an acute cataract with three points of fibrosis extending from the posterior to the anterior capsule. The patient underwent phacoemulsification surgery with visual rehabilitation and improved vision of 20/20. We hypothesized that the occurrence of acute cataract was related to the inappropriate use of focused ultrasound. causes treatment procedures radiofrequency complications 54yearold yearold 54 year old 2060 20 60 20/60 capsule 2020 20/20 5 206 2 6 20/6 202 20/2 20/

RESUMO: O objetivo deste relato é descrever o auxílio da elastografia por impulso de força de radiação acústica (ARFI) no diagnóstico de dois casos de tumores malignos da bainha dos nervos periféricos em canídeos. Ambos os pacientes apresentavam claudicação em membro torácico e já haviam sido tratados clinicamente por outros profissionais, sem resposta ao tratamento ou histórico de trauma. Ao exame físico, foi observada atrofia muscular em apenas um dos membros torácicos, nos dois casos. Foi realizado exame ultrassonográfico axilar. Na avaliação modo B, foi observada a presença de estrutura nodular, predominantemente hipoecogênica, heterogênea, irregular, não encapsulada e com reatividade adjacente, medindo aproximadamente 20.1 mm x 15.4 mm no primeiro caso e 18.3 mm x 10.7 mm no segundo caso. Foi realizada elastografia ARFI, demonstrando a presença de áreas de maior rigidez, com velocidade de ondas de cisalhamento média de 4.12 m/s (caso 1) e 4.35 m/s (caso 2), sugerindo malignidade. Em ambos os casos, foi realizada amputação do membro afetado e os nódulos removidos foram encaminhados para análise histopatológica, na qual se obteve o diagnóstico de tumor maligno da bainha de nervo periférico. Os métodos ultrassonográficos realizados nesses casos foram essenciais para o diagnóstico e conduta terapêutica.

ABSTRACT: This report described the use of acoustic radiation force impulse (ARFI) elastography in the diagnosis of two cases of canine malignant peripheral nerve sheath tumors. Both patients presented with lameness in the thoracic limb and no response to previous clinical treatment or trauma history. Physical examination revealed muscular atrophy in one of the thoracic limbs, in both dogs. B-mode axillary ultrasound showed the presence of a predominantly hypoechogenic, heterogeneous, irregular, nonencapsulated nodule with adjacent reactivity, measuring approximately 20.1 mm x 15.4 mm in the first case and 18.3 mm x 10.7 mm in the second. ARFI elastography was performed, showing areas of significant stiffness, with an average shear wave velocity of 4.12 m/s (case 1) and 4.35 m/s (case 2), suggesting malignancy. In both cases, the affected limb was amputated, and the tumors sent for histopathological analysis, which were; subsequently, diagnosed as malignant tumors of the peripheral nerve sheath. The ultrasonographic methods used were essential in the diagnosis and therapeutic conduct.

The sixth IPCC report states that a proper conception of climate justice that can address the complexity of the phenomenon of anthropogenic climate change as a whole requires considering not only one but rather three dimensions of justice today: redistributive, procedural, and recognition dimensions. In this article, my focus is on exploring the latter dimension, drawing special attention to climate policies addressing cultural-identity issues. In the first section, I illustrate how climate policies can be connected to discriminatory practices against minority cultures and their identities. To do so, I take the struggles of Black movements against environmental racism and the struggles of Indigenous peoples against a colonialist cultural heritage as case studies. In the second section, I look into the most advanced normative model to address the dimension of recognition, its advantages, and how it addresses the so-called ‘institutionalization of cultural patterns’ in climate policies: the Nancy Fraser model. Finally, in the third section, I investigate an aspect that remains open. It concerns the matter of how to use institutional authority to ‘deinstitutionalize’ non-ecological cultural patterns, while respecting pluralism and avoiding falling into the risks of institutional paternalism. today redistributive procedural article culturalidentity identity issues section identities so studies advantages socalled called institutionalization patterns Finally open ‘deinstitutionalize deinstitutionalize nonecological non ecological paternalism

ABSTRACT A patient presented with corneoscleral thinning five months after the treatment of suspected ocular squamous surface neoplasia with mitomycin-C and interferon. For tectonic and aesthetic purposes, we decided to perform lamellar corneoscleral transplantation. The approach used established new tectonic support and corneal homeostasis. This technique might be an option in similar cases. mitomycinC mitomycin C interferon purposes transplantation homeostasis cases

The inhibition of the fatty acid amide hydrolase (FAAH), an endocannabinoid system component, emerged as a potentially new therapeutic target for a range of clinical disorders such as acute and chronic pain. Some α-ketoheterocycle derivatives demonstrated interesting analgesic and anti-inflammatory activities in vitro. Ligand-Based Drug Design techniques such as knowledge graph convolutional networks (kGCN) and hologram quantitative structure-activity relationship (HQSAR) using α-ketoheterocycle derivatives from five different datasets were generated to discover the relation between the chemical structures and the inhibition activity. Meanwhile, structure-based drug design simulations as interaction fields (MIF), molecular docking, and ligand sites studies (LSI) from FAAH were performed using Autogrid software and FTmap/FTsite servers. The results of both studies were merged to propose predictive models. The resulting kGCN model demonstrated adequate accuracy area under the curve by receiver operating characteristic (AUC-ROC 0.7922). From contribution maps of the Ligand-Based Drug Design (LBDD) models and the generated probes using MIF and LSI, it was observed that the oxazole ring, the ketone group, and the apolar chain present in the structures of the inhibitors are important, besides the evidence of the Cys269 and Val270 residues importance for the potential interaction, confirmed by carried docking studies. These fragments and structural information can be used to carry out new FAAH potential inhibitors studies and report kGCN as an accurate classification technique.

Abstract We investigated how the FBI persecuted the Black Panther Party of the United States through the COINTELPRO program between 1968 and 1971, and verified that such practices follow a pattern similar to that of other counterintelligence activities mobilized in the repression of political organizations of the left and the black movement in the 20th Century, repeating a consolidated modus operandi at the time. In terms of methodology, we proposed a content analysis of primary sources little studied in Brazil – internal FBI memos and the final report of the US Senate Committee (“Church Committee”) dedicated to investigating government intelligence activities – and a systematization of secondary sources that have already analyzed the material in the United States. The relevance of the paper is to highlight the role of repression in studies of sociopolitical movements and mobilizations, mainly in the case of the Black Panthers – in which it occupies a specific importance to understand obstacles to develop the organization and its own dissolution process. 196 1971 th Century time methodology Church Committee” mobilizations process 19 197 1

ABSTRACT: We described the pathological findings of an abortion associated with Yersinia enterocolitica infection in an ewe. A late-gestation aborted ovine fetus and placenta were submitted for necropsy. Pathologic changes were restricted to the chorioallantois. Grossly, cotyledons and intercodilenary regions had areas of mild red discoloration, and cotyledons were covered with a small amount of fibrin. Histological lesions consisted of multifocal, severe necrotizing and fibrinosuppurative placentitis with fibrinoid vasculitis and mineralization. Bacterial culture of lung, abomasum, and placenta samples yielded pure growth of Y. enterocolitica. This report described the first case of infection by Yersinia enterocolitica causing ovine abortion in Brazil.

ABSTRACT Blastic plasmacytoid dendritic cell neoplasia (BCDPN) is a rare and generally aggressive hematological malignancy, which requires early recognition. Below, the clinical course of a 72-year-old patient with NCDPB is described, whose most relevant findings included the presence of skin lesions, organomegaly, and bone marrow infiltration. After the diagnosis, systemic chemotherapy was indicated, with a good response; however, after 2 months the lesions recurred and the patient died. In this disease it is necessary to establish the differential diagnosis with lymphoproliferative disorders, lymphoid and acute myeloid leukemias, with the morphological analysis of the neoplastic cells being an important aspect for adequate diagnostic guidance.

RESUMEN La neoplasia de células dendríticas plasmocitoides blásticas (NCDPB) es una malignidad hematológica poco frecuente y generalmente agresiva, por lo cual se requiere su reconocimiento precoz. A continuación, se describe el curso clínico de una paciente de 72 años con NCDPB, en cuyos hallazgos más relevantes destacó la presencia de lesiones cutáneas, organomegalias, infiltración de la médula ósea. Posterior al diagnóstico se indicó quimioterapia sistémica, con buena respuesta, no obstante, a los 2 meses presentó recidiva de lesiones y la paciente falleció. En esta enfermedad es necesario establecer el diagnóstico diferencial con trastornos linfoproliferativos, leucemias linfoides y mieloides agudas, constituyendo el análisis morfológico de las células neoplásicas un aspecto importante para una adecuada orientación diagnóstica.
