Nuclear Medicine in Brazilian Health System.

Nuclear Medicine plays an important role in the management of patients with chronic diseases, especially oncological and cardiovascular conditions. In this study, an analysis of the evolution of this field in Brazil was conducted within the framework of the Unified Health System. Retrospective analyses from 2015 to 2021 of public data were performed.

[Inequalities in the adequacy to consultation calendar for children under 5 years old in the Food and Nutritional Surveillance].

The Ministry of Health recommends a minimum appointment schedule in childcare to monitor growth and development. The objective was to analyze the adequacy of the minimum appointment schedule for children under 5 years of age, with at least one anthropometric follow-up registered with the Food and Nutrition Surveillance System (SISVAN) between 2008 and 2020. The sample size comprised 23,453,620 children under the age of 5, and 103,773,311 records.

Molecular and functional convergences associated with complex multicellularity in Eukarya.

A key trait of Eukarya is the independent evolution of complex multicellular (CM) in animals, plants, fungi, brown algae and red algae. This phenotype is characterized by the initial exaptation of cell-cell adhesion genes followed by the emergence of mechanisms for cell-cell communication, together with the expansion of transcription factor gene families responsible for cell and tissue identity. The number of cell types (NCT) is commonly used as a quantitative proxy for biological complexity in comparative genomics studies.

Optimal timing of pharmacoinvasive strategy and its impact on clinical and economic outcomes in patients with ST-elevation myocardial infarction: a real-world perspective.

Background: The pharmacoinvasive (PhI) strategy is the standard-of-care for ST-elevation myocardial infarction (STEMI) patients when primary percutaneous coronary intervention (pPCI) is unfeasible. Optimal timing for post-fibrinolytic PCI (lysis-PCI) remains elusive. Therefore, this study aimed to assess the clinical and economic impacts of early vs.

Triiodothyronine (T3) increases the expression of the amphiregulin (AREG) oncogene by activating extranuclear pathways in MCF-7 breast cancer cells.

Objective: Considering that the αvβ3 integrin plays an important role in tumor metastasis, this study investigated the involvement of these pathways in mediating the triiodothyronine (T3) effects on amphiregulin () expression.

Materials And Methods: We treated MCF-7 cells with T3 (10 nM) for 1 hour in the presence or absence of inhibitors for αvβ3 integrin (RGD peptide), MAPK (PD98059), PI3K (LY294002), and protein synthesis (cycloheximide [CHX]). A control group (C) received no T3 or inhibitors.
