Brain metabolism perturbation can contribute to traits and diseases. We conducted a genome-wide association study for cerebrospinal fluid (CSF) and brain metabolite levels, identifying 205 independent associations (47.3% new signals, containing 11 new loci) for 139 CSF metabolites, and 32 independent associations (43.8% new signals, containing 4 new loci) for 31 brain metabolites. Of these, 96.9% (CSF) and 71.4% (brain) of the new signals belonged to previously analyzed metabolites in blood or urine. We integrated the metabolite quantitative trait loci (MQTLs) with 23 neurological, psychiatric and common human traits and diseases through colocalization to identify metabolites and biological processes implicated in these phenotypes. Combining CSF and brain, we identified 71 metabolite-trait associations, such as glycerophosphocholines with Alzheimer's disease, O-sulfo-L-tyrosine with Parkinson's disease, glycine, xanthine with waist-to-hip ratio and ergothioneine with inflammatory bowel disease. Our study expanded the knowledge of MQTLs in the central nervous system, providing insights into human traits.

Background: Grit, resilience and a growth mindset are traits that help health professional students respond positively and adapt to the challenges of the clinical learning environment. The aim of this study was to determine if a 5-week education-based intervention can enhance grit, resilience and a growth mindset in physiotherapy students on clinical placement.
Methods: In this single group intervention study, physiotherapy students participated in a 5-week group-based, online educational intervention for 1 h per week during their first clinical placement.

Mitochondria are dynamic systems adapted to the different cellular demands. In this context, it is hypothesized that lipids, and particularly fatty acids, are also affected by these adaptations and supported at transcriptional level. By analyzing seven mammalian organs from rats, covering the three germ layers and belonging to the four basic types of tissue, we evaluated the differences in the lipidome's fatty acid profiles, calculated fatty acid-derived parameters including susceptibility to lipid peroxidation, and estimated enzymatic activity.

These beliefs are often rooted in essentialist thinking that gender is distinct, non-overlapping, unchangeable, and biologically based. Gender is a multidimensional social concept, partly informed by perceptions of sex, which is a distinct concept referring to a collection of biological traits.

Forensic identification at fire scenes faces three core challenges: distinguishing cause of death (antemortem burning versus postmortem corpse burning), reconstructing criminal behavior (arson versus accident), and preserving evidence (thermal destruction versus artificial tampering). This case study systematically demonstrates the application value of burn trace characteristics in arson investigation through a typical intentional homicide and corpse burning case. Based on a three-dimensional analytical framework of human burn-behavioral characteristics, a systematic pathway incorporating reconstruction of arson/corpse burning processes and identification of body relocation behavior was established.

Background: Cisplatin is a commonly used chemotherapeutic across numerous cancer types that can cause neurotoxicities in patients, including peripheral sensory neuropathy, tinnitus, hearing loss, and vertigo.
Objective: We aimed to evaluate, for the first time, how genetic ancestry impacts cisplatin-induced neurotoxicities and if disparities are related to population differences in allele frequency.
Methods: In a cohort of cisplatin-treated testicular cancer survivors, relationships between genetic ancestry and neurotoxicities, medications, and lifestyle factors were assessed using logistic regression and Kruskal-Wallis tests and multiple pairwise comparisons using the Wilcoxon rank-sum test (Benjamini-Hochberg adjustment).
