Sarcopenia, the progressive loss of skeletal muscle mass and function, represents a major public health concern due to its impact on mobility, independence, and quality of life, especially in oldadults. Current treatment strategies primarily rely on resistance training and nutritional support, with particular emphasis on adequate protein intake to stimulate muscle protein synthesis. In this review, we provide an overview of th...

Strontium hexaferrite (SrM) powders were prepared by solid-state reaction using celestite and magnetite/hematite. Energy dispersive X-ray fluorescence spectrometry, X-ray diffractometry (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometry were used for analyses. The precursor ores were purified by hand-sorting and magnetic separation. Magnetic separation yielded 75% magnetite and 25% hematite in iron or...

Macrourid species constitute the main bycatch in Southern Ocean toothfish longline fisheries. We report the first confirmed record of Whitson's grenadier, Macrourus whitsoni , in the South Georgia toothfish fishery. Mitochondrial cox1 DNA barcoding confirmed its presence in bycatch samples collected around South Georgia and the northern South Sandwich Islands, with approximately 1% divergence from its congener, M. caml . Haplo...

Dunaliella salina is one of several carotenoid sources that have been considered to enhance gonad coloration in sea urchins, although its relatively high cost may limit routine use in commercial echinoculture. Identifying the minimum feeding duration required to achieve optimal results may offer a cost-effective strategy. This study evaluated a cold-extruded diet supplemented with 1.5% D. salina (DUN) as a finishing diet for P...

Cannabis sativa L. has a long history of medicinal and industrial use, with female flowers as the primary source of bioactive cannabinoids and terpenoids synthesized in glandular trichomes. Despite its importance, the genetic mechanisms governing flower development, sex determination, and secondary metabolite biosynthesis remain incompletely understood. Here, we combined transcriptomic and comparative genomic analysis to eluci...

Cold‐water fishes, such as salmonids, face environmental stresses resulting from climate change. We examined the thermal acclimation response of the hatchery‐reared versus wild, native brook trout ( Salvelinus fontinalis ) to explore how the contractile properties and gene expression of their myotomal muscle might shift to mitigate the impact of a warming environment. Hatchery fish were acclimated to three temperatures (4, 10...

Seagrass meadows are key blue carbon (C) ecosystems, storing large amounts of organic C over centuries. Their climate benefits may be reduced by methane (CH 4 ) emissions, whose microbial and environmental descriptors in Zostera noltii meadows, dominant seagrass in North‐Western Europe, remain poorly understood. We studied CH 4 fluxes, CH 4 ‐producing and consuming microbial communities and sediment physicochemical parameters...

Introduction: Lung cancer remains one of the leading causes of death worldwide, accounting for approximately 1.8 million deaths annually. In this context, low health literacy is frequent and represents a barrier to effective education on screening and early detection. The aim of this study was to translate, culturally adapt, and validate the Lung CAM questionnaire for use in Brazil, enabling the assessment of population litera...

Purpose Despite growing recognition of stress-related health inequities, the role of nativity and acculturation in shaping the relationship between chronic stress and cancer outcomes among Hispanic populations remains poorly understood. The purpose of this study was to examine whether nativity factors (United States (US) citizenship status and length of time residing in the US modify the association between allostatic load (AL...

Host‐associated microbes are key components of animal health and physiology, with particular importance for determining responses to pathogen infection. The gut microbiota is highly variable at the individual level, being shaped by a multitude of factors including diet, social behaviour, and age. Yet the relative influence of these traits on microbiota composition, and the consequences of this variation for host responses to p...

Coastal lagoons are dynamic systems where the mode of nutrient input, continuous or pulsed, or a combination, can significantly affect plankton community structure and function. We conducted a spring field microcosm experiment in a Mediterranean lagoon to evaluate how three nutrient delivery regimes influence planktonic dynamics, using biomass measurements and extracellular enzyme activity (EEA) as functional indicators. Conti...

Although Macrourus species are the main by‐catch across Southern Ocean longline fisheries, including around South Georgia, the lack of species‐specific data has hindered effective management and ecological understanding. Aggregation of macrourids at genus level masks critical interspecific differences in life‐history strategies and vulnerabilities to fishing. Here, we provide the first comprehensive biological assessment of th...

In many parts of the world, natural resources are primarily managed by governance arrangements at the local level. Those arrangements range from collective, such as cooperatives and associations, to individualistic, such as patrons and owner‐operators. A key question is how such arrangements influence resource use and associated social and ecological outcomes. We hypothesize that sustainable resource use is not associated with...
