Research ArticleOpen accessEvery word in the titleThe Role of Living, Resident Bacterial Biofilm Populations in the Osseointegration of Oral ImplantsStephen Nelson, Honghua Hu et al.This study presents a human jawbone model which explains bone health, disease and quality and the osseointegration interphase, at the cell level. Curation of 454 pyrosequencing data obtained from 153 bone, serous-effusion and granulation samples taken from 40 patients during two-stage dental implant installation, revealed a 20 phyla jawbone microbiome with total genera of 387. Multivariate statistical ordination of curated … …Current Research in Dentistry, Vol. 14, Issue 1 · 16 Nov 2023 · 8,245 accessesView PDFCite
Case ReportOpen accessEvery word in the titleBacterial Biofilm Persistence in Human Jawbone Following Tooth Extraction: Implications of Surgical Debridement and Resident Population-Shift for Oral ImplantsStephen Nelson, Honghua Hu et al.Intra-radicular infection theory assumes that when an infected tooth is extracted, the main source of infection is removed and any residual contaminating bacteria are killed by the immune response, then normal healing ensues. This study investigated whether bacteria and bacterial biofilms persisted in deep bone space following tooth extraction. The study was conducted on two adult male patients seeking dental … …Current Research in Dentistry, Vol. 14, Issue 1 · 31 May 2023 · 6,861 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleEcophysiology of Chirostoma Jordani Pisces: Atherinopsidae. Habitat Characterization and Population Dynamics in a Periurban Lake (Xochimilco, México)Latournerié-Cervera José Román, Rangel-Nambo María Isabel, Alma Rosa Estrada-OrtegaChirostoma Jordani is an endemic species of the Mexican plateau, whose population, due to anthropogenic causes, has experienced a notable decrease from 2000 to the present, putting its permanence in its natural habitat at risk. Therefore, the objectives of this research were focused on evaluating the population dynamics of C. Jordani through its size and weight distributions and growth rate … …American Journal of Agricultural and Biological Sciences, Vol. 16, Issue 1 · 23 Jan 2021 · 7,546 accessesView PDFCite
