Biochemical analysis of vitreous humor and synovial fluid in the estimation of early postmortem interval: A meta-analytical approach.

The estimation of the postmortem interval (PMI) is a significant challenge in legal medicine and forensic sciences due to the dynamic and continuous decomposition of organisms after death. Thanatochemistry has emerged as a promising area to estimate PMI by measuring the concentrations of postmortem biochemical markers. This systematic review and meta-analysis aimed to summarize evidence on postmortem biochemical alterations in vitreous humor (VH) and synovial fluid (SF) to estimate early PMI.

Demographic evolution and natural increase projection of the Yanomami indigenous population in Brazil.

The Yanomami population, residing in Brazil's largest indigenous reserve in the Amazon Rainforest, face significant health challenges exacerbated by external threats such as infectious diseases, malnutrition, and mercury contamination from illegal mining. These issues, coupled with inadequate healthcare provision, have led to an alarming increase in mortality rates and potentially threaten the long-term survival of the Yanomami community. This ecological study utilized demographic data from the Special Secretariat of Indigenous Health to explore the demographic evolution and natural increase of the Yanomami Indigenous population in Brazil from 2003 to 2022.

Recommendations for procedures related to the evidence chain of custody in forensic anthropology in Brazil.

Forensic anthropologists perform specialised analysis, mainly involving skeletonised human remains, cadavers in advanced stages of decomposition, disassociated elements from the human body, and human remains in extreme carbonisation. The main objectives of the forensic anthropology expertise are human identification and assisting in determining the cause and manner of death. Estimating the time since death is also a priority for some cases, especially ones involving missing persons.

Testing the Olze and Timme Methods for Dental Age Estimation in Radiographs of Brazilian Subadults and Adults.

Aim: This study aimed to test the applicability of the methods proposed by Olze et al. (2012) and Timme et al. for dental age estimation in Brazilian subadults and adults.
