Minimal repeats are ubiquitous sites of crossover and recombination across the human genome
BMC GenomicsBackground Crossover and recombination create genetic diversity that reflects differences in the DNA sequences of different organisms. We previously reported that trinucleotide 2-repeat units (T2Us) are sites of crossover and consequent colonization ...

Quantitative whole-tissue 3D imaging reveals bacteria in close association with mouse jejunum mucosa
npj Biofilms and Microbiomes, 2023 Because the small intestine (SI) epithelium lacks a thick protective mucus layer, microbes that colonize the thin SI mucosa may exert a substantial effect on the host.

Advanced Functional Materials, EarlyView.A 3D bone scaffold with osteogenic properties and capable of hardening in vivo is developed. The scaffold is implanted in a ductile state, and a phase transformation of the ceramic induces the stiffening and strengthening of the scaffold in vivo. Abstract Calcium phosphate 3D printing has revolutionized customized bone grafting.

Candida colonization on the denture of diabetic and non-diabetic patients
Dental Research Journal, 2009 Background: Oral candidiasis is a common opportunistic infection in diabetic patients. Presence of denture in the oral cavity of diabetic patients can promote Candida colonization and results in the higher incidence of oral and systemic candidiasis.

DENTA: A Dual Enzymatic Nanoagent for Self‐Activating Tooth Whitening and Biofilm Disruption
Advanced Functional Materials, EarlyView.The nanoapatite with dual enzymes (DENTA) accumulates in dentinal tubules, reducing hypersensitivity caused by dental nerve exposure and facilitating continuous ROS generation through salivary glucose for effective, long‐term whitening. The dentin structures remain non‐destructive due to the low concentration of ROS, demonstrating excellent cell ...
