Hepatic morphology and serum biochemical profile according to dry and rainy seasons in Pygocentrus nattereri (Characiformes: Serrasalmidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract This study investigated the physiological and morphological adaptations of the liver of the carnivorous fish Pygocentrus nattereri (piranha) in response to seasonal variations (dry and rainy seasons) in the Brazilian Pantanal. The objective was to describe how the liver, a central organ in metabolic regulation, responds to environmental ...

Pelvic breadth and juvenile locomotor energetics: Implications for the obstetrical dilemma hypothesis across human growth in past and present humans

open access: yesThe Anatomical Record, EarlyView.
Abstract The obstetrical dilemma hypothesis (ODH) proposes an evolutionary trade‐off between obstetric requirements and locomotor performance. However, whether external pelvic breadth measures influence walking energetics during human growth remains poorly understood.

Mapping the distribution of Meissner corpuscles throughout the human hand: Sex‐ and age‐dependent variations

open access: yesThe Anatomical Record, EarlyView.
Abstract Meissner corpuscles are rapidly adapting mechanoreceptors involved in tactile discrimination in human glabrous hand skin. Detailed information on their regional distribution and variation across age, sex, and hand side remains limited. This study mapped Meissner corpuscles in 17 phalangeal and palmar regions from 46 individuals (27 male and 19

Cortical bone geometry and static gravitational loads in neosauropod dinosaurs: Implications for biomechanical constraints on terrestrial gigantism

open access: yesThe Anatomical Record, EarlyView.
Abstract Sauropod dinosaurs achieved unprecedented terrestrial gigantism, raising questions about the biomechanical limits of bone under extreme gravitational loads. We estimated static gravitational pressures (Pg) on appendicular cortical bone in neosauropods, including diplodocoids, brachiosaurids, and titanosaurs.

Potential for Carotenoid and Other Bioproducts Production by a Brazilian Dunaliella salina Isolate Using a High Photon Flux Density Strategy

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Dunaliella species are among the most significant biological sources of carotenoids, notably beta‐carotene. Given that chemical synthesis offers a more cost‐effective alternative to biotechnological cultivation, optimizing production strategies is essential for economic viability.

Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

Design of azine antioxidants for sustainable biodiesel: integrating structural characterization and molecular modeling

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The growing global demand for sustainable energy solutions has intensified the search for renewable alternatives to fossil fuels, with biodiesel emerging as a promising candidate due to its biodegradability and lower emissions. However, its large‐scale application is limited by low oxidative stability, which compromises storage and performance.

Development and evaluation of a microwave‐assisted continuous system for olive pomace oil extraction and in‐line esterification/transesterification

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study developed and evaluated a preliminary continuous microwave‐assisted system integrating oil extraction from olive pomace and subsequent conversion into fatty acid ethyl esters (FAEEs) in a single processing unit. A conventional microwave oven was adapted for continuous operation by incorporating magnetron power adjustment and a ...

Sustainable Innovation and Impact on Triple Bottom Line Performance: Are Innovation Types Simple Mediators?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the way sustainable innovation, conceptualized as a second‐order construct integrating sustainable orientation and innovation culture, impacts triple bottom line (TBL) performance. It also examines the mediating roles of product, process, organizational, and marketing innovations.

Generative Artificial Intelligence Performance on University‐Level Human Anatomy Examinations: A Structured Narrative Review and Proposed MATRIX‐Anatomy Framework

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Generative artificial intelligence (GenAI) can perform strongly on written anatomy examinations, but whether such scores represent anatomical competence remains uncertain because results vary with the model, assessment, protocol, modality, scoring, and comparator.
