1. Evaluation of sediment contamination by urban sewage in a stretch of Capibaribe River, Pernambuco, Brazil
Anthropic activities are responsible for the increase in environmental contamination, especially in aquatic systems, demanding studies to assess and monitor contamination levels in different water bodies. We have done a chemical characterization of eleven sediments in order to evaluate the level of contamination by domestic sewage from the Capibaribe River,

2. Are hemoglobin-derived peptides involved in the neuropsychiatric symptoms caused by SARS-CoV-2 infection?
Follow-up of patients affected by COVID-19 has unveiled remarkable findings. Among the several sequelae caused by SARS-CoV-2 viral infection, it is particularly noteworthy that patients are prone to developing depression, anxiety, cognitive disorders, and dementia as part of the post-COVID-19 syndrome. The multisystem aspects of this disease suggest that mul

3. Identifying conceptions of the covalent bond: an analysis from a systematic review
The covalent bond is a classical topic in science education because it is fundamental to a considerable number of other concepts and by its ability to interpret several chemical phenomena. However, the process of learning this concept presents some difficulties discussed here. This article brings together the conceptions related to the covalent bond, identif

4. Congenitally Corrected Transposition of the Great Arteries in the Adult
ABSTRACT Introduction: Congenitally corrected transposition of the great arteries (CCTGA) is a rare anomaly. Current data available regarding adult cases is derived from small series, information simultaneously presented in pediatric publications, and one classical multicenter study. This review, not aimed to exhaust the subject, has the purpose to examine

5. ECG Signals Classification Using Overlapping Variables to Detect Atrial Fibrillation
ABSTRACT In the present work a method for the detection of the cardiac pathology known as atrial fibrillation is proposed by calculating different information, statistics and other nonlinear measures over ECG signals. The original database contains records corresponding to patients who are diagnosed with this disease as well as healthy subjects. To formulate

6. Similarity as an extension of symmetry and its application to superrationality
Abstract In this paper we present a concept of similarity in games, on which to ground alternative solution concepts, some of which differ from the classical notions in the field. In order to do this we impose a constraint on players’ beliefs that amounts to a variant of the well-known symmetry principle in classical bargaining theory. We show how this sim

7. Clinical and molecular profile of a Brazilian cohort of patients with classical BCR-ABL1-negative myeloproliferative neoplasms
ABSTRACT Background: The classical BCR-ABL1-negative myeloproliferative neoplasms (MPNs) are Polycythemia Vera (PV), Essential Thrombocythemia (ET) and Primary Myelofibrosis (PMF). In developing countries, there are few reports that truly reveal the clinical setting of these patients. Therefore, we aimed to characterize a single center MPN population with a

8. Investigation of MHC gamma block C4A and C4B polymorphisms in unrelated hematopoietic stem cell transplantation
ABSTRACT Background: Immunological life-threatening complications frequently occur in post-hematopoietic stem cell transplantation (HSCT), despite matching recipient and donor (R/D) pairs for classical human leukocyte antigens (HLA). Studies have shown that R/D non-HLA disparities within the major histocompatibility complex (MHC) are associated with adverse

9. HÁ ALGO NOVO NO RECONHECIMENTO MOLECULAR APLICADO À QUÍMICA MEDICINAL?
In Medicinal Chemistry, the knowledge, the study and the understanding of the intermolecular interactions inherent to the molecular recognition of a ligand by its target bioreceptor are essential. This is because understanding these interactions, which define the molecular complementarity between the two, is the key to analyze critically structure-activity r

10. ANTROPOLOGIA E ECONOMIA. TENTANDO FAZER UMA CONEXÃO SIGNIFICATIVA: ENTREVISTA COM KEITH HART
Resumo Keith Hart narra sua trajetória intelectual desde seus primeiros cursos em letras clássicas até sua conversão à antropologia. Acentua a mudança de perspectiva teórico-conceitual provocada por sua geração e os impactos dessas novas pesquisas realizadas na África urbana, o que, por sua vez, deu outra feição à antropologia econômica que, ao

11. Bayesian factor analysis for mixed data on management studies
Abstract Purpose Factor analysis is the most used tool in organizational research and its widespread use in scale validations contribute to decision-making in management. However, standard factor analysis is not always applied correctly mainly due to the misuse of ordinal data as interval data and the inadequacy of the former for classical factor analysis.

12. Rectal carcinoma with synchronous liver metastases
Resumo Introdução O câncer colorretal está entre as neoplasias mais prevalentes no mundo, apresentando a uma taxa de mortalidade relativamente alta. Ele corresponde a 20% a 30% de todos os casos de câncer colorretal; 25% dos casos apresentam doença metastática síncrona. Este estudo teve como objetivo revisar as abordagens atuais de tratamento para p
