The oral microbiome of patients with ischemic stroke predicts their severity and prognosis

open access: yesFrontiers in Immunology, 2023
Background and objectivesStroke is a common group of cerebrovascular diseases that can lead to brain damage or death. Several studies have shown a close link between oral health and stroke.

The newest Oxford Nanopore R10.4.1 full-length 16S rRNA sequencing enables the accurate resolution of species-level microbial community profiling

open access: yesApplied and Environmental Microbiology, 2023
The long-read amplicon provides a species-level solution for the community. With the improvement of nanopore flowcells, the accuracy of Oxford Nanopore Technologies (ONT) R10.4.1 has been substantially enhanced, with an average of approximately 99%.

Alternative conformations in Escherichia coli 16S ribosomal RNA. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1985
Partially denatured 16S rRNA from 30S ribosomes shows features of secondary structure in electron microscopy that correspond to the well accepted secondary structure model derived from chemical modification and phylogenetic data. However, a very different conformation is seen in precursor 16S rRNA sequences contained within 30S pre-rRNA transcripts ...

Response to neoadjuvant chemotherapy in early breast cancers is associated with epithelial–mesenchymal transition and tumor‐infiltrating lymphocytes

open access: yesMolecular Oncology, EarlyView.
Epithelial–mesenchymal transition (EMT) and tumor‐infiltrating lymphocytes (TILs) are associated with early breast cancer response to neoadjuvant chemotherapy (NAC). This study evaluated EMT and TIL shifts, with immunofluorescence and RNA sequencing, at diagnosis and in residual tumors as potential biomarkers associated with treatment response.

Association between semen microbiome disorder and sperm DNA damage

open access: yesMicrobiology Spectrum
DNA fragmentation index (DFI), a new biomarker to diagnose male infertility, is closely associated with poor reproductive outcomes. Previous research reported that seminal microbiome correlated with sperm DNA integrity, suggesting that the microbiome may

The complete mitochondrial genome of Glossaulax reiniana (Littorinimorpha: Naticidae)

open access: yesMitochondrial DNA. Part B. Resources, 2018
In the present study, the complete mitochondrial genome of Glossaulax reiniana was determined using the next-generation sequencing. The circular genome was found to be 15,254 bp in length and had an overall nucleotide composition of 30.6% A, 14.1% C, 15 ...

Molecular Approaches to Studying Microbial Communities: Targeting the 16S Ribosomal RNA Gene.

open access: yesJournal of UOEH, 2016
Culture-independent methods to detect microorganisms have been developed in parallel with traditional culture-based methods ever since the classification of bacteria based on 16S rRNA gene sequences was advocated in the 1970s.

Transcriptome‐wide analysis of circRNA and RBP profiles and their molecular relevance for GBM

open access: yesMolecular Oncology, EarlyView.
CircRNAs are differentially expressed in glioblastoma primary tumors and might serve as therapeutic targets and diagnostic markers. The investigation of circRNA and RNA‐binding proteins (RBPs) interactions shows that distinct RBPs play a role in circRNA biogenesis and function.

MOLECULAR IDENTIFICATION OF SEVERAL CLINICALLYIMPORTANT BACTERIA INCLUDING ENTEROBACTERIA BYPARTIAL 16S RIBOSOMAL RNA GENE SEQUENCE COMPARISON

open access: yesZdravniški Vestnik, 2008
BACKGROUND The correct identification of bacterial isolates is paramount for the correct diagnosis andtreatment of patients. The standard approach for bacterial identification relies on phenotypic tests, which are often time-consuming and unreliable when
