A field resource for the glioma cerebrospinal fluid proteome: impacts of resection and location on biomarker discovery.

Background: While serial sampling of glioma tissue is rarely performed prior to recurrence, cerebrospinal fluid (CSF) is an underutilized longitudinal source of candidate glioma biomarkers for understanding therapeutic impacts. However, the impact of key variables to consider in longitudinal CSF samples for monitoring biomarker discovery, including anatomical location and post-surgical changes, remains unknown.

Methods: Aptamer-based proteomics was performed on 147 CSF samples from 74 patients, 71 of whom had grade 2-4 astrocytomas or grade 2-3 oligodendrogliomas.

Complete genome sequence of strain JM503A, a genetically tractable dental abscess clinical isolate.

The dynamic impact of location and resection on the glioma CSF proteome.

Unlabelled: While serial sampling of glioma tissue is rarely performed prior to recurrence, cerebrospinal fluid (CSF) is an underutilized longitudinal source of candidate glioma biomarkers for understanding therapeutic impacts. However, the impact of key variables to consider in longitudinal CSF samples, including anatomical location and post-surgical changes, remains unknown. To that end, pre- versus post-resection intracranial CSF samples were obtained at early (1-16 days; n=20) or delayed (86-153 days; n=11) timepoints for patients with glioma.

Stratification of Fusobacterium nucleatum by local health status in the oral cavity defines its subspecies disease association.

The ubiquitous inflammophilic oral pathobiont Fusobacterium nucleatum (Fn) is widely recognized for its strong association with inflammatory dysbiotic diseases and cancer. Fn is subdivided into four subspecies, which are historically considered functionally interchangeable in the oral cavity. To test this assumption, we analyzed patient-matched dental plaque and odontogenic abscess clinical specimens and examined whether an inflammatory environment selects for/against particular Fn subspecies.

The prevalence of subspecies in the oral cavity stratifies by local health status.

The ubiquitous inflammophilic pathobiont is widely recognized for its strong association with a variety of human dysbiotic diseases such as periodontitis and oral/extraoral abscesses, as well as multiple types of cancer is currently subdivided into four subspecies: subspecies () ( (), and (). Although these subspecies have been historically considered as functionally interchangeable in the oral cavity, direct clinical evidence is largely lacking for this assertion. Consequently, we assembled a collection of oral clinical specimens to determine whether subspecies prevalence in the oral cavity stratifies by local oral health status.

Who is in the driver's seat? Parvimonas micra: An understudied pathobiont at the crossroads of dysbiotic disease and cancer.

Recent advances in our understanding of microbiome composition at sites of inflammatory dysbiosis have triggered a substantial interest in a variety of historically understudied bacteria, especially among fastidious obligate anaerobes. A plethora of new evidence suggests that these microbes play outsized roles in establishing synergistic polymicrobial infections at many different sites in the human body. Parvimonas micra is a prime example of such an organism.

Children with severe early childhood caries: streptococci genetic strains within carious and white spot lesions.

Background And Objectives: Mutans streptococci (MS) are one of the major microbiological determinants of dental caries. The objectives of this study are to identify distinct MS and non-MS streptococci strains that are located at carious sites and non-carious enamel surfaces in children with severe early childhood caries (S-ECC), and assess if cariogenic MS and non-cariogenic streptococci might independently exist as primary bacterial strains on distinct sites within the dentition of individual children.

Design: Dental plaque from children (N=20; aged 3-6) with S-ECC was collected from carious lesions (CLs), white spot lesions (WSLs) and non-carious enamel surfaces.

Mutans streptococci genetic strains in children with severe early childhood caries: follow-up study at one-year post-dental rehabilitation therapy.

Background: Genotypic strains of cariogenic mutans streptococci (MS) may vary in important virulence properties. In previous published studies, we identified 39 MS strains from pediatric patients undergoing full-mouth dental rehabilitation, including the removal and/or repair of carious lesions and application of antimicrobial rinse and fluoride varnish.

Objectives: The objectives of this current 1-year follow-up study are to assess the variability of MS strains that occur at 1-year post-rehabilitation and characterize the xylitol-resistance properties of MS strains that predominate.

Children with severe early childhood caries: pilot study examining mutans streptococci genotypic strains after full-mouth caries restorative therapy.

Loss of Xenopus tropicalis EMSY causes impairment of gastrulation and upregulation of p53.

EMSY interacts directly with BRCA2 and links the BRCA2 pathway to sporadic breast and ovarian cancer. It also interacts with BS69 and HP1b, both of which are involved in chromatin remodelling, and with NIF-1 and DBC-1 in the regulation of nuclear receptor-mediated transcription. Here we investigate the function of EMSY during amphibian development, and in doing so provide the first loss-of-function analysis of this protein.

Cell free expression put on the spot: advances in repeatable protein arraying from DNA (DAPA).

We have previously described the 'DNA array to protein array' (DAPA) method for microarraying of proteins expressed by cell-free systems in situ on the array surface. In this technique, a DNA array on one slide acts as the template for generating a protein array on a second slide, mediated by a cell free lysate between the two juxtaposed slides. Here we explore the feature of the repeatability of the technology, in which the same DNA array is reused several times, and use the method to generate a microarray of 116 diverse proteins.
