Multidisciplinary insights into Late Pleistocene-Holocene palaeoenvironment at the archaeo-palaeontological Loltún Cave site in Yucatán, Mexico

Abstract A lack of well-dated archaeological and palaeontological sequences containing proxy-based palaeoenvironmental information has hindered the reconstruction of long-term human-biodiversity interactions in Mexico. Here, we re-evaluate the stratigraphy of the Huechil Chamber...

Development and Characterization of Bioactive Sodium Alginate Dressings Incorporating Melipona beecheii Honey for Wound Healing Applications

Healing wounds and skin lesions has been practiced since ancient times, and various mechanisms have been used to treat them, ranging from bandages and herbs to ointments and modern alternatives such as dressings. This work aimed to develop bioactive dressings for wound healing. D...

Study of the impact of etching mixtures on the surface chemistry and electrocatalytic activity of multilayer Ti3C2Tx MXenes

Ti₃C₂Tₓ MXenes are commonly obtained through the chemical etching of the Ti₃AlC₂ MAX phase; however, the influence of the composition of the etching medium on their physicochemical properties and electrocatalytic performance requires further detailed understanding. This study com...

Are hyaluronic acid synthases widely encoded in fungi?

Hyaluronic acid (HA) is a biologically versatile polysaccharide synthesized by vertebrates and several microbial pathogens. To date, Cryptococcus neoformans CPS1p is the only reported bona fide hyaluronic acid synthase (HAS) in fungi, which is functionally related to bacterial HA...

Physicochemical, Mechanical and Biological Characterization of a PCL/PLA-Based Biocomposite for Potential Dental Post Applications in Primary Teeth

Early childhood caries frequently affects maxillary anterior primary teeth, and their rehabilitation remains a clinical challenge due to the lack of suitable resorbable intracanal posts. This study aimed to develop and characterize a biodegradable polymer-ceramic biomaterial for...
