Chronic alcohol consumption compromises gut barrier integrity and promotes endotoxemia: Implications for sepsis susceptibility in immunocompromised hosts

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Chronic alcohol exposure disrupts intestinal barrier integrity, resulting in a leaky gut and enhanced translocation of lipopolysaccharide (LPS) and microbial products into the systemic circulation. Alcohol‐induced endotoxemia drives exaggerated pro‐inflammatory responses, mitochondrial damage, and activation of the cGAS–STING pathway, particularly in ...

The origins of governments: from anarchy to hierarchy [PDF]

open access: yes, 2010
We analyze development trajectories of early civilizations where population size and technology are endogenous, and derive conditions under which such societies optimally ‘switch’ from anarchy to hierarchy – when it is optimal to elect and support a ...

A Doxorubicin‐Loaded Liposomes Baghdadite System for Localized Osteosarcoma Therapy and Bone Regeneration

open access: yesAdvanced NanoBiomed Research, EarlyView.
This study presents a multifunctional Baghdadite ceramic implant integrating doxorubicin‐loaded liposomes via ion‐assisted plasma polymer coating for localized osteosarcoma therapy. The platform enables drug retention, sustained release, tumor cell inhibition, osteoconductivity, and antibacterial activity, offering a mechanically robust strategy for ...

Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

open access: yesThe Anatomical Record, EarlyView.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...

Admixture as a source for HLA variation in Neolithic European farming communities

open access: yesGenome Biology
Background The northern European Neolithic is characterized by two major demographic events: immigration of early farmers from Anatolia at 7500 years before present, and their admixture with local western hunter-gatherers forming late farmers, from ...

Human Processing of Rodents in Patagonia: The Relevance of Historical and Ethnographical Data for Archaeological Interpretations [PDF]

open access: yes, 2019
The consumption of small mammals was a widespread practice between indigenous societies worldwide. Modern taphonomic studies carried out upon bone assemblages from archaeological sites in northern Patagonia (Argentina) demonstrate thatCaviomorph rodents ...

The relationship between form and function of the carnivore mandible

open access: yesThe Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...
