AI Article Synopsis

  • The study aimed to investigate whether the shift from the late antique to early medieval period in Croatia negatively affected periodontal health by examining 1,118 skulls for various dental conditions.
  • Findings revealed varying prevalence rates of dental calculus, alveolar bone resorption, and other dental issues across different regions and time samples, with notable differences but no overall negative impact linked to the transition period.
  • The conclusion suggests that the transition did not harm periodontal health, indicating that further research is needed to better understand the living conditions of ancient populations.

Article Abstract

Objective: We tested the hypothesis that the transition from the late antique to the early mediaeval period in Croatia had a negative impact on the periodontal health.

Methods: 1118 skulls were examined for dental calculus, alveolar bone resorption, fenestrations, dehiscences and root furcation involvement.

Results: The prevalence of teeth with calculus varied from 40.7% in the LA sample of continental parts of Croatia to 50.3% in the LA sample of Adriatic Croatia. The prevalence of alveolar bone resorption ranged between 21.2% in the EM sample from continental Croatia and 32.3% in the LA sample from Adriatic Croatia. The prevalence of individuals with alveolar bone dehiscences varied from 8.6% in the LA sample from continental Croatia up to 15.0% in the EM sample from Adriatic Croatia. The prevalence of individuals with alveolar bone fenestrations varied from 21.5% in the LA sample from Adriatic Croatia up to 36.2% in the LA sample from continental Croatia. The prevalence of individuals with exposed root bifurcations or trifurcations varied from 9.0% in the EM sample from Adriatic Croatia up to 20.7% in the EM sample from continental Croatia. Statistically significant differences were found between samples.

Conclusion: The transition from the late antique to the early mediaeval period in Croatia did not have a negative impact on periodontal health. Studies of periodontal health of ancient populations should be performed to provide a better and more reliable reconstruction of living conditions in the past.

Due to the complex physical properties of low-permeability glutenite reservoirs, the oil recovery rate with conventional development is low. Surfactants are effective additives for enhanced oil recovery (EOR) due to their good ability of wettability alteration and interfacial tension (IFT) reduction, but the reason why imbibition efficiencies vary with different types of surfactants and the mechanism of enhanced imbibition in the glutenite reservoirs is not clear. In this study, the imbibition efficiency and recovery of surfactants including the nonionic, anionic, and cationic surfactants as well as nanofluids were evaluated and compared with produced water (PW) using low-permeability glutenite core samples from the Lower Urho Formation in the Mahu oil field.

Diazotrophs have made significant contributions to marine nitrogen cycles. However, their distribution patterns and determined mechanisms have not been fully understood, particularly at the small regional scales. Here, the diazotrophic community structure by different sample sizes (0.

Microbial activity in the deep continental subsurface is difficult to measure due to low cell densities, low energy fluxes, cryptic elemental cycles and enigmatic metabolisms. Nonetheless, direct access to rare sample sites and sensitive laboratory measurements can be used to better understand the variables that govern microbial life underground. In this study, we sampled fluids from six boreholes at depths ranging from 244 m to 1,478 m below ground at the Sanford Underground Research Facility (SURF), a former goldmine in South Dakota, United States.

Continental glaciations during the Pleistocene Epoch created complex systems of aquifers and aquitards across many northern regions of the Earth. The low hydraulic conductivities of glacial till aquitards suggest that limited recharge will reach the underlying aquifers, potentially preserving old groundwaters. Here, we characterize the recharge history in intertill and buried valley aquifers in Saskatchewan, Canada using C, H, He δH, δO, and major ions.

In recent years, significant efforts have been made to improve methods for genomic studies of admixed populations using local ancestry inference (LAI). Accurate LAI is crucial to ensure that downstream analyses accurately reflect the genetic ancestry of research participants. Here, we test analytic strategies for LAI to provide guidelines for optimal accuracy, focusing on admixed populations reflective of Latin America's primary continental ancestries-African (AFR), Amerindigenous (AMR), and European (EUR).
