Lactobacillus probiotics have been investigated in periodontitis. However, the effects of the genus Bifidobacterium on periodontitis are hardly known. This study evaluated the effects of the probiotic (PROB) Bifidobacterium animalis subsp. lactis (B. lactis) HN019 as an adjunct to scaling and root planing (SRP) in rats with experimental periodontitis (EP). At baseline, 32 rats were assigned to ...
The signal recognition particle (SRP) cotranslationally targets proteins to cell membranes by coordinated binding and release of ribosome-associated nascent polypeptides and a membrane-associated SRP receptor. GTP uptake and hydrolysis by the SRP-receptor complex govern this targeting cycle. Because no GTPase-activating proteins (GAPs) are known for the SRP and SRP receptor GTPases, however, it...
OBJECTIVE Our research aimed to detect the efficacy of non-surgical periodontal treatment with Nd: YAG laser and scaling and root planning (SRP) for chronic periodontitis. METHODS We recruited chronic periodontitis patients who have more than four teeth with clinical pocket depth of 4-8 mm. These teeth were distributed in four different zones within the oral cavity. Moreover, the teeth were s...
The bacterial version of the mammalian signal recognition particle (SRP) is well conserved and essential to all known bacteria. The genes for the Streptomyces lividans SRP components have been cloned and characterized. FtsY resembles the mammalian SRP receptor and the S. lividans SRP consists of Ffh, a homologue of the mammalian SRP54 protein, and scRNA, which is a small size RNA of 82 nt in le...
BACKGROUND The first step in the co-translational targeting of secretory proteins to the endoplasmic reticulum membrane involves the recognition of signal sequences by the 54 kDa subunit of the signal recognition particle (SRP) as they emerge from the ribosome. It has recently been proposed that the nascent polypeptide-associated complex (NAC) contributes to the fidelity of targeting by modulat...
The purpose of this study is to evaluate the effect of the avocado/soybean unsaponifiables (ASU) on the treatment of induced periodontitis in rats. Periodontitis was induced in 84 rats via ligature placement around the second upper molar, which was removed after 7 days, and scaling and root planning (SRP) was performed at this time. Subsequently, the rats were randomly allocated to four groups ...
The signal recognition particle is a cytoplasmic RNA-protein complex that mediates translocation of secretory polypeptides into the endoplasmic reticulum. We have used a Xenopus oocyte microinjection assay to determine how signal recognition particle (SRP) RNA is exported from the nucleus. Following nuclear injection, SRP RNA accumulated in the cytoplasm while cytoplasmically injected SRP RNA d...
OBJECTIVE The aim of this study was to assess the bactericidal efficacy of antimicrobial photodynamic dynamic therapy (aPDT) as an adjunct to scaling and root planing (SRP) against periodontal pathogens. BACKGROUND DATA SRP followed by laser therapy has better clinical outcomes than conventional SRP alone. MATERIALS AND METHODS The question addressed was "Does aPDT as an adjunct to SRP exhi...
Protein-RNA and protein-protein interactions involved in the assembly of the signal recognition particle (SRP) were examined using fluorescence spectroscopy. Fluorescein was covalently attached to the 3'-terminal ribose of SRP RNA following periodate oxidation, and the resulting SRP RNA-Fl was reconstituted into a fluorescent SRP species that was functional in promoting translocation of secreto...
OBJECTIVE The aim of this study was to develop and validate a quantitative anti-signal recognition particle (SRP) autoantibody serum ELISA in patients with myositis and longitudinal association with myositis disease activity. METHODS We developed a serum ELISA using recombinant purified full-length human SRP coated on ELISA plates and a secondary antibody that bound human IgG to detect anti-S...
