Zirconia (Y-TZP) ceramics are considered as posterior fixed partial denture (FPD) materials; however, their applications are limited due to chipping. The use of monolithic lithium disilicate (LiDi) glass ceramics in posterior FPDs can be advantageous. This in vitro study aims to compare the loads until failure of posterior Y-TZP-FPDs and LiDi-FPDs before and after aging.

Chinese milk vetch (CMV) is widely recognized as the leading leguminous green manure utilized in the rice-green manure rotation system throughout southern China. While bacteria that form symbiotic relationships with CMV are responsible for fixing a significant portion of nitrogen (N) within agroecosystems. diazotrophic organisms play an essential role in the N cycle and enhance the pool of N readily accessible to plants.

Objective: To compare the in vitro scan accuracy (trueness and precision) of recently introduced wireless intraoral scanners (IOSs) to commonly used wired IOSs in different fixed partial denture (FPD) situations.
Methods: Three partially edentulous maxillary models with implants located at different sites (lateral incisors [Model 1]; right canine and first molar [Model 2]; right first premolar and first molar [Model 3]) were digitized with wireless (Primescan 2 [P2] and TRIOS 5 [T5]) and wired (Primescan [P1] and TRIOS 3 [T3]) IOSs (n=14 per IOS-model pair). The models were also digitized with an industrial-grade optical scanner for their reference scans.

Macroalgae widely distribute in intertidal zones, one of blue carbon organisms. However, the regulatory mechanisms of tide on the carbon sequestration of macroalgae are still unclear. This study explored the effects of desiccation-rewetting cycles induced by tide on dissolved organic carbon (DOC) release from Ulva pertusa, which is prevalent from high to low tidal zones.

Formalin preservation of museum specimens has long been considered a barrier to molecular research due to extensive crosslinking and chemical modification. However, recent optimisation of hot alkaline lysis and proteinase K digestion DNA extraction methods have enabled a growing number of studies to overcome these challenges and conduct genome-wide re-sequencing and targeted locus-specific sequencing. The newest, and perhaps most unexpected utility of formalin preservation in archival samples is its ability to preserve in situ DNA-protein interactions at a molecular level.
