Thermal persistence and physicochemical modification of inorganic gunshot residue (IGSR)

Journal of Forensic Sciences, EarlyView.
Abstract In the medicolegal context, GSR analysis plays a key role in clarifying the dynamics of firearm‐related deaths, including lesion identification and firing distance determination. However, postmortem alterations of the body, such as thermal exposure, may influence the analysis of lesions and complicate interpretation.

Metabarcoding replicate detection frequency tracks ddPCR copy number for cod and herring eDNA in ancient marine sediments

Methods in Ecology and Evolution, EarlyView.
Abstract Detecting environmental DNA (eDNA) from rare or low‐abundance aquatic species remains a major challenge, particularly when it is highly degraded, present at low concentrations, and dominated by DNA from non‐target taxa. These challenges are further amplified in sedimentary ancient DNA (sedaDNA) studies, where thousands of years can degrade ...

Weighted prevalence of biochemically verified substance use in healthy adolescents across the USA

Addiction, EarlyView.
Abstract Background and aims Adolescent substance use is a significant public health concern, though the scope of the problem is difficult to ascertain given reliance on self‐reported substance use information. Recent, large cohort studies in adolescents and young adults suggest underreporting of substance use.

Sex Steroids Measurement by Mass Spectrometry in Hypogonadal Men in a Real‐World Setting: Serum Estradiol (E2) and E2 to Total Testosterone Ratio Do Not Differ Between Patients With Klinefelter Syndrome and Non‐Klinefelter Syndrome Hypogonadism

Andrology, EarlyView.
ABSTRACT Background Traditionally, Klinefelter syndrome (KS) was considered a clinical condition associated with hyperestrogenism. Aim To compare circulating sex steroids, particularly estrogens, in a cohort of KS and non‐KS hypogonadal men. Materials and Methods A cohort of hypogonadal men, treated and untreated, was prospectively enrolled in a real ...

6‐Nitrodopamine as a Novel Mediator of Prostatic Smooth Muscle Function in Mouse and Human

Andrology, EarlyView.
ABSTRACT Background Epithelium‐derived catecholamines contribute to local regulation of genitourinary smooth muscle function, but the role of the endogenous 6‐nitrodopamine (6‐ND) in the prostate remains unknown. Objectives To determine whether 6‐ND is produced by mouse and human prostate and its role in smooth muscle regulation.
