Periodontal conditions, oral Candida albicans and salivary proteins in type 2 diabetic subjects with emphasis on gender

<p>Abstract</p> <p>Background</p> <p>The association between periodontal conditions, oral yeast colonisation and salivary proteins in subjects with type 2 diabetes (T2D) is not yet documented. The present study aimed to assess the relationship between these variables in type 2 diabetic subjects with reference to gender.</p> <p>Methods</p> <p>Fifty-eight type 2 diabetic subjects (23 males and 35 females) with random blood glucose level ≥ 11.1 mmol/L were investigated. Periodontal conditions (plaque index [PI], bleeding on probing [BOP], probing pocket depth [PD] (4 to 6 mm and ≥ 6 mm), oral yeasts, salivary immunoglobulin (Ig) A, IgG and total protein concentrations, and number of present teeth were determined.</p> <p>Results</p> <p>Periodontal conditions (PI [<it>p </it>< 0.00001], BOP [<it>p </it>< 0.01] and PD of 4 to 6 mm [<it>p </it>< 0.001], salivary IgG (μg)/mg protein (<it>p </it>< 0.001) and salivary total protein concentrations (<it>p </it>< 0.05) were higher in type 2 diabetic females with <it>Candida albicans </it>(<it>C. albicans</it>) colonisation compared to males in the same group. Type 2 diabetic females with <it>C. albicans </it>colonisation had more teeth compared to males in the same group (<it>p </it>< 0.0001).</p> <p>Conclusion</p> <p>Clinical and salivary parameters of periodontal inflammation (BOP and IgG (μg)/mg protein) were higher in type 2 diabetic females with oral <it>C. albicans </it>colonisation compared to males in the same group. Further studies are warranted to evaluate the association of gender with these variables in subjects with T2D.</p

RNA Extraction from Equine Samples for Equine Influenza Virus

The primary goals of this chapter are to discuss common viral RNA isolation and purification methods that are routinely used by various diagnostic laboratories and to highlight the advantages and drawbacks of each method and to identify the most suitable and reliable method to increase the sensitivity and specificity of RT-PCR assays for the detection of equine influenza virus (EIV) in clinical specimens. Our experiences and review of literature show that magnetic bead-based nucleic extraction methods (manual and automatic) work well for isolation and purification of EIV RNA from nasal swab specimens. Furthermore, most of the information presented in this chapter could be directly applicable to isolation and purification of nucleic acids (both DNA and RNA) from other equine clinical samples

Guidelines for Setting Up a mRNA Sequencing Experiment and Best Practices for Bioinformatic Data Analysis

RNA-sequencing, commonly referred to as RNA-seq, is the most recently developed method for the analysis of transcriptomes. It uses high-throughput next-generation sequencing technologies and has revolutionized our understanding of the complexity and dynamics of whole transcriptomes.In this chapter, we recall the key developments in transcriptome analysis and dissect the different steps of the general workflow that can be run by users to design and perform a mRNA-seq experiment as well as to process mRNA-seq data obtained by the Illumina technology. The chapter proposes guidelines for completing a mRNA-seq study properly and makes available recommendations for best practices based on recent literature and on the latest developments in technology and algorithms. We also remark the large number of choices available (especially for bioinformatic data analysis) in front of which the scientist may be in trouble.In the last part of the chapter we discuss the new frontiers of single-cell RNA-seq and isoform sequencing by long read technology
