The wolves suspected of man-eating in the 1880s likely ate very little human flesh and mostly consumed a diet similar to herbivores and omnivores.

This study suggests that using stable isotope analysis on various tissues can effectively reconstruct individual life histories, providing insights into both the individual and broader population from the Romano-Christian period in Egypt.

This study hypothesizes that a mummified 19th Century girl in San Francisco died of severe undernourishment potentially due to a bacterial-borne disease, highlighting historical health challenges mitigated by modern sanitation and medicine.

This study analyzed stable isotopes in animal fibers from Bronze and Iron Ages sites in Xinjiang, China, revealing that caprines and cattle primarily consumed C3 plants, while some Iron Age individuals showed unusual high C4 plant intake likely linked to millet foddering practices.

In this study, adding δ34S isotope analysis to models modestly improved precision in estimating grizzly bears' salmon and terrestrial diets, but contributed little new information.

This review discusses the use of stable isotope analysis in primate hair to study feeding behavior and reports no new results; the authors call for methodological refinement in field and lab procedures.

This study suggests that the shoulder guard hair of captive sika deer is effective for hair analysis, providing insights into growth patterns and isotopic changes that could aid future research on wild deer using hair samples.

This study concluded that the process of mummification disfigures facial features, making identification challenging, but commercial shrunken heads retain more defining features compared to ceremonial ones.

In this study, the authors found that the shoulder guard hair of captive sika deer most accurately reflects dietary information during winter coat growth, useful for analyzing wild deer hair samples.

This article reviews analysis techniques in LC-MS/MS and discusses the potential use of a novel in-sample calibration curve method, but reports no new experimental results.

This study found that a new analytical approach revealed an increased brain pregnenolone level following finasteride treatment in a mouse model, suggesting potential for improved understanding of neurosteroid roles in brain excitability.

This study found that carbon and nitrogen isotope analysis of cattle hair reflects dietary and farm system differences, offering insights into cattle nutritional ecology and agroecosystem characteristics.

In this study, the isotopic fractionation between tissues and diets of captive Japanese macaques was quantified, particularly noting hair's response to diet changes in controlled conditions, but these findings underscore the complexity of reconstructing long-term dietary history.

This study observed that eliminating positional error in hair segment analysis can improve understanding of changes in isotopic composition, aiding the identification of pathological conditions and dietary patterns.

This study found that high-resolution tusk isotope profiles from an African elephant can serve as a proxy for the seasonality of diet and precipitation, helping to reconstruct vegetation and climate in modern and fossil ecosystems.

These investigations described in the study demonstrate how geochemical techniques can be applied to biological studies in Yellowstone, finding significant mercury accumulation in trout and grizzly bears which correlates with hydrothermal sources.

This study developed and validated a mass spectrometric method to measure hydroxy-androgens in serum, which aids in understanding androgen synthesis in castration resistant prostate cancer.

This study found that young women with female-pattern hair loss exhibit increased testosterone production rates while dihydrotestosterone production rates remain within or below the normal range.

This study reported that using 2D solid-state NMR techniques on extensively labeled mouse fur improves resolution in detecting chemical shifts and secondary structure features, potentially aiding the analysis of the effects of commercial or therapeutic treatments on specific amino acids.

In this study, researchers observed low variability in hair formoterol concentrations for COPD patients with stable adherence, but inter-patient differences and other factors may limit the effectiveness of hair analysis as a reliable tool for assessing medication adherence.

This study found that hair analysis is an effective non-invasive method for assessing metabolic fluctuations, showing stable advanced glycation end products levels that correlate with age and differ significantly between diabetic and non-diabetic rats.

In this study, researchers observed that graded calorie restriction in mice led to changes in stable isotope ratios and elemental content in bone collagen and hair keratin, potentially indicating intensified mobilization of endogenous proteins and altered bone collagen structure with increased dietary stress.

This commentary discusses the challenges of matrix effects in LC–MS analysis and introduces the concept of a matrix effect factor using stable isotopically labeled internal standards to improve analysis reliability.

This study found that increased δ¹⁵N values in hair keratin could indicate physiological stress among early settlers with pathological conditions in Belleville, Ontario, while δ¹³C values remained relatively stable.

In this study, silver oxide-based nanoparticles were used to ionize analytes and detect specific target molecules through adduct formation with silver isotopes, facilitating signal correlation with these molecules.

This study utilized a UHPLC-HRMS method to identify eight active pharmaceutical ingredients, such as ketoconazole and minoxidil, in 26 out of 100 analyzed cosmetic products.

This review discusses the growing use of scalp hair for elemental analysis in various fields and highlights advancements in analysis techniques, including the future potential of laser ablation ICP-MS, but reports no new clinical results.

This study developed a new measurement procedure using isotope dilution-liquid chromatography-tandem mass spectrometry for accurate quantification of DHEAS in human serum or plasma, demonstrating high selectivity, sensitivity, and low measurement uncertainty, making it suitable for routine standardization and clinical evaluation.

This study reported high analytical performance of an RMP for DHT quantification, with the ability to differentiate between 5α-DHT and 5β-DHT isomers, making it suitable for routine assay standardization and clinical sample evaluation.
