Identification of high-risk oral leukoplakia (OLK) using combined Raman spectroscopic analysis of brush biopsy and saliva samples: A proof of concept study.

The gold standard method of diagnosis of oral leukoplakia (OLK) is a tissue biopsy followed by histological examination. Raman spectroscopic studies of cytological brush biopsy and saliva samples have previously been shown to differentiate low (no and mild dysplasia) and high risk (moderate and severe dysplasia) OLKs, discriminant models of cellular samples achieving higher specificity, whereas those based on saliva samples achieved higher sensitivity. The current study combines the spectral data sets of cell and saliva samples in an attempt to improve the overall efficiency of the discriminating models.

Variation in the commissioning of specialist weight management services and bariatric surgery across England: Results of a freedom of information-based mapping exercise across the 42 integrated Care Systems of England.

Specialist weight management services including bariatric surgery are commissioned within regions of England called Integrated Care Systems (ICSs) with eligibility and treatment guidelines determined as part of the National Institute for Health and Care Excellence (NICE) guidance. Reported variation in commissioning and bariatric surgery eligibility criteria has not been previously mapped. Freedom of Information (FOI) requests provide a tool, supported by legislation, to ask questions of public authorities including ICSs such that they must respond accurately.

Evaluation of single and multispecies biofilm formed in the static and continuous systems.

Biofilms consisting of multiple species of bacteria compared to biofilms of single species are common in natural environments including food contact surfaces. The objective of this study was to understand the biofilm formation and the efficiency of sodium hypochlorite (50 ppm/5 mins) on the single and multiple species biofilm of Pseudomonas fluorescens, Staphylococcus aureus, and Listeria monocytogenes formed on stainless steel surfaces in static and continuous systems. The cell concentration of Listeria in the dual and triple species biofilm in the continuous system (7.

The protein composition of human adenovirus replication compartments.

Human adenoviruses are double-stranded DNA viruses that replicate in the cell nucleus and induce the formation of replication compartments (RCs) that are critical in viral replication and control of virus-host interactions. RCs are specialized virus-induced subnuclear microenvironments where not only viral genome replication and expression are orchestrated but also host proteins that restrict viral replication are co-opted and subverted. The protein composition of these RCs remains largely unexplored.
