Forensic Tools for Species Identification of Skeletal Remains: Metrics, Statistics, and OsteoID.

Although nonhuman remains constitute a significant portion of forensic anthropological casework, the potential use of bone metrics to assess the human origin and to classify species of skeletal remains has not been thoroughly investigated. This study aimed to assess the utility of quantitative methods in distinguishing human from nonhuman remains and present additional resources for species identification. Over 50,000 measurements were compiled from humans and 27 nonhuman (mostly North American) species.

Structural and Functional Brain Imaging in Long-Term Survivors of Childhood Acute Lymphoblastic Leukemia Treated With Chemotherapy: A Systematic Review.

Background: The effect of chemotherapy on brain development in long-term survivors of pediatric acute lymphoblastic leukemia (ALL) was systematically reviewed.

Methods: A systematic search of Pubmed, Scopus, and PsycINFO databases was conducted to identify articles published between January 2000 and February 2020 that implemented magnetic resonance imaging to assess brain structure and function in pediatric ALL survivors (diagnosed younger than 21 years of age). The review included articles that were published on children diagnosed with ALL between 0 and 21 years of age and treated with chemotherapy-only protocols.

Blood recalcification time. A simple and reliable test to monitor heparin therapy.

The applicability of blood recalcification time as a laboratory test to assess and thereby regulate heparin anticoagulation was evaluated. Normal values for blood recalcification time ranged from 65 to 135 seconds, with a mean and standard deviation of 99 and 12 seconds, respectively. Duplicate determinations showed a mean variation of 5%.
