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 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.

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.

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.

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 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.

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 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.

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 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 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.

In this study, L-cysteine treated with the Trivedi Effect® showed significantly increased isotopic abundance ratios, which may enhance its stability and shelf-life.

In this study, nitrogen starvation in Chlorella sp. FC2 IITG led to increased lipid accumulation by altering the expression of enzymes involved in various metabolic pathways, suggesting potential for genetic engineering of microalgae.

This synthesis report details the successful development of a C-14 labeled isotopomer of LY300502, a 5α-reductase inhibitor, through a multi-step radiochemical process.

This study developed a method using UHPLC-MS/MS and MSPE to detect trace amounts of sex hormones in cosmetics, finding progestins and estrogens in some products, and performed a preliminary safety evaluation for residual progesterone in hair loss prevention cosmetics.

In this study, researchers developed de novo designed hetero-bifunctional proteins as an alternative approach for targeted protein degradation, successfully targeting BCL-xL for degradation in cells and inducing apoptosis, which may expand the range of addressable E3 ligases and disease targets.

Certain fungi and bacteria help orchid seeds germinate and plants grow better.

This study reported that polymeric nanofibers containing minoxidil sulphate showed effective encapsulation and stability, with minimal concentration loss over six months, making them potentially ideal for delivering this unstable drug in a more visually appealing and easier-to-apply form.

This review examines the role of root hair specification and nutrient acquisition in plants, emphasizing the need for further genetic research to understand the mechanisms influencing root hair development and growth.

This study evaluated a new anti-baldness product, IPSTiC patch hair, designed to treat androgenetic alopecia, and reported that it effectively inhibits NO radical and 5α-reductase activity while maintaining safety and stability, suggesting its potential for topical use.

This study developed a stable, cosmetically appealing formulation for the topical delivery of the peptide FOL-005, enhancing skin permeation and maintaining stability by keeping the peptide solid and in a water-free environment with particle sizes under 10 µm.

This study reports that a new boron/nitrogen-doped carbon nano-onion-based delivery system for doxorubicin enhanced its uptake and anticancer effects in specific cancer cell types, while reducing cardiotoxicity in human heart cells.

This study developed and tested two methods to accurately quantify hair growth rates in polar, black, and grizzly bears using dye application and isotopically labelled amino acids, revealing growth rate variations by individual and season.

In this study, researchers found that the KLHL24-ΔN28 protein variant disrupts hair follicle stem cells in a mouse model, leading to premature hair loss by degrading keratin 15.

This review examines recent advances in bioelectronic nanogenerators for anti-cancer therapy, highlighting various transducing strategies such as photodynamic therapy and electrical stimulation, while also discussing the potential mechanisms for tissue repair and the challenges that lie ahead.
