13. Heart Transplantation for Chagas Cardiomyopathy
Abstract Heart transplantation (HT) is an established treatment for patients with advanced heart failure (HF). Chagas disease (CD), caused by the Trypanosoma cruzi (T.cruzi) is an important cause of HF in Latin America. Considering CD is a chronic infectious disease, the use of immunosuppressive therapy after HT can reactivate T. cruzi infection and compromi

16. Paralisia facial como complicação neurológica da SARS-CoV-2
Abstract Cardiac hypertrophy and dysfunction are a significant complication of chronic Chagas disease, with heart failure, stroke, and sudden death related to disease progression. Thus, understanding the signaling pathways involved in the chagasic cardiac hypertrophy may provide potential targets for pharmacological therapy. Herein, we investigated the impli

18. Dereplication of Aporphine Alkaloids by UHPLC-HR-ESI-MS/MS and NMR from Duguetia lanceolata St. -Hil (Annonaceae) and Antiparasitic Activity Evaluation
Although the genus Duguetia is well known for producing alkaloids as chemical constituents, there are no reports of alkaloids identified in the species D. lanceolata. Thus, aiming to identify the chemical composition of this species, the dereplication of alkaloidic phase was performed by use of ultra-high performance liquid chromatography high resolution ele

20. Megacólon chagásico na Venezuela
RESUMO O megacólon chagásico é a segunda causa mais frequente de manifestação das formas digestivas da doença de Chagas (parasitose do Trypanosoma cruzi), caracterizado por sintomas pseudo-oclusivos progressivos ou constipação crônica, causado por uma alteração no funcionamento da musculatura da parede do cólon. Na Venezuela, os casos da doença

21. Extracellular vesicles isolated from Trypanosoma cruzi affect early parasite migration in the gut of Rhodnius prolixus but not in Triatoma infestans
The protozoan Trypanosoma cruzi has the ability to spontaneously secrete extracellular vesicles (EVs). In this paper, T. cruzi EVs derived from epimastigote forms were evaluated during interaction with triatomine bugs Rhodnius prolixus and Triatoma infestans. T. cruzi EVs were purified and artificially offered to the insects prior to infection with epimastig

22. Epidemiological features, echocardiographic findings, and parasite load in patients with Chagas disease
Abstract INTRODUCTION Chagas disease is a major public health problem that is endemic in Brazil and Latin America. This study aimed to determine the socioeconomic, demographic, and clinical characteristics of 171 patients (mean age, 45 years; female, 65%) with Chagas disease at Hospital Universitário de Brasília, Federal District, Brazil. METHODS We im

23. Survey of Trypanosoma (Kinetoplastida: Trypanosomatidae) Infection in Monte Negro Municipality, State of Rondônia, Western Amazon, with First Record of T. evansi in the state.
Abstract INTRODUCTION: Trypanosomes can infect humans and animals. This is the first record of the occurrence of Trypanosoma evansi in Rondônia. METHODS: Blood samples were collected from 7 dogs and 22 humans. Furthermore, triatomines and tabanids were collected. RESULTS: It was observed that 42.8% of the dogs tested positive for T. evansi and 14.3% pr

24. Spatial distribution of triatomine bugs in a Chagas disease endemic region in Brazil
Abstract INTRODUCTION: Trypanosoma cruzi is the etiological agent of Chagas disease (CD), a zoonotic infection transmitted by triatomine bug vectors to human beings. Although the story of this parasitic infection was born in Brazil and here this has made major step forward information, the same cannot be said about the actual distribution of the triatomine
