In Brazil, efforts towards the regulatory acceptance and implementation of innovative methods to replace experimental animal use in various fields began to gather force in 2008, with the approval of (the Arouca Law). This law represented a milestone, as it created the National Council for the Control of Animal Experimentation (CONCEA) to deal with the ethical and legal issues related to the use of laboratory animals. In 2014, CONCEA put together a framework for expanding the implementation of non-animal methodologies for use in research and education. It also promoted the regulatory acceptance in Brazil of 24 test guidelines, including 15 approaches. It should be emphasised that, in Brazilian legislation, is generally based on the toxicological endpoint and not on the category of product, as tends to be the case in other countries (e.g. cosmetics in the European Union). The resolution-dependent deadlines for the obligatory replacement of methods with the CONCEA-approved tests are 2019 and 2021. Brazil has advanced considerably towards the replacement of animal experimentation, and in certain aspects, this has been in a highly progressive manner. However, there is still a lot of work to be done, especially considering the current political scenario with reduced investment in research, development and innovation. The chronology of significant events following the approval of the Arouca Law, which have contributed to the promotion of the Three Rs alternatives in Brazil, will be examined.

Background And Aim: Patellofemoral pain syndrome (PFPS) is a disease that clinically presents with retro-patellar and peripatellar pain that affects primarily physically active individuals. This study aims to estimate the prevalence of PFPS in Saudi Arabia and the variables that contribute to its occurrence.
Objectives: This multicenter, cross-sectional study aimed to explore the prevalence of patellofemoral pain in Saudi Arabia.

Background: In Japan, three doses of vitamin K are administered to neonates as prophylactic regimens against vitamin K deficiency bleeding (VKDB). In this study, we aimed to evaluate the efficacy of this prophylactic vitamin K regimen using the hepaplastin test (HPT) performed one, two weeks, and one month after birth. The secondary aim of this study was to evaluate the utility of HPT screening in healthy neonates.

Background: Despite improvements in our understanding of glioblastoma pathophysiology, there have been no major improvements in treatment in recent years. Animal models are a vital tool for investigating cancer biology and its treatment, but have known limitations. There have been advances in glioblastoma modeling techniques in this century although it is unclear to what extent they have been adopted.

Bufalin, which is isolated from toad venom, exerts positive effects on hearts under pathological circumstance. We aimed to investigate the effects and mechanisms of bufalin on myocardial I/R injury. In vivo, bufalin ameliorated myocardial I/R injury, which characteristics with better ejection function, decreased infarct size and less apoptosis.

This study explored the early diagnosis and prognostic value of copeptin in non-ST-segment elevation acute coronary syndrome (NSTE-ACS). 171 patients with chest pain or myocardial ischemia symptoms were enrolled. Patients with NSTE-ACS were further divided into the non-ST-elevation myocardial infarction (NSTEMI) and unstable angina (UA).
