In 2017 the British Journal of Biomedical Science published 35 articles in the various disciplines that comprise biomedical science. These were 6 reviews, 22 original articles, 6 'In Brief' short reports and one guideline. Of these, the majority were in clinical chemistry (one review, six data papers), microbiology (one review, four data papers), cellular pathology (four data papers) and virology (one review, two data papers). There were two data papers in transfusion science, whilst haematology, cytopathology and immunology were each represented by one review and one data paper...

INTRODUCTION: Red blood cell distribution width (RDW) is elevated in various inflammatory diseases, but its clinical significance in Henoch-Schönlein purpura nephritis (HSPN) in unknown. The aim of this study was to determine the value of RDW as a risk factor or marker for HSPN in children. METHODS: This was a case-control study of 105 Henoch-Schönlein purpura (HSP) patients, 120 HSPN patients and 192 healthy controls. The relationship between RDW-coefficient of variation (RDW-CV) and the clinical characteristics of HSPN patients was determined by a multiple logistic regression analysis (MVLRA)...

BACKGROUND AND AIM: The emergence of resistance against antimicrobial agents has led to the development of more efficient agents and new techniques for treatment of various microbial infections. The aim of the present study is to determine the antibacterial and antifungal activity of bare and chitosan coated Fe3O4 nanoparticles (NPs) against five organisms, Escherichia coli (E. coli), Bacillus subtilis (B. subtilis), Candida albicans (C. albicans), Aspergillus niger (A. niger) and Fusarium solani (F...

BACKGROUND: Fibrosis markers are useful for the prediction of cirrhosis but clinical scores such as King's score, AST-Platelet ratio index (APRI), Biotechnology research center (BRC), Fibrosis routine test (FRT), Fibro-α score and Fibro-quotient (FibroQ) have limited accuracy for diagnosing significant fibrosis. We hypothesised that new markers (reflecting the balance between hepatic fibrogenesis and fibrolysis) together with other indirect fibrosis markers would together construct a more sensitive and specific score capable of identifying fibrosis than existing scores...

BACKGROUND: MiRNAs may be associated with the risk of uterine sarcoma and related molecular mechanism remains unclear. METHODS: A total of 101 patients with uterine sarcoma (cases) and 54 healthy subjects (controls) were enrolled. The levels of serum miR-152, miR-205, miR-222, miR-24, miR-150 and sirtuin 1 (SIRT1, an NAD +-dependent class III histone deacetylase) were measured by qRT-PCR. HeLa cells were transfected with the mimics of miR-152 and miR-24. The autophagic rates, and the levels of SIRT1 and acetylation of microtubule-associated protein 1A/1B-light chain 3 (LC3) were measured...

BACKGROUND: Mohs micrographic surgery (MMS) involves evaluation of frozen tissue sections to determine complete circumferential and deep tissue margin clearance of skin tumours. PrestoCHILL and Presto stainer devices are two new innovative tools which bring benefits of automation, speed and efficiency to the preparation of frozen section analysis in MMS. The devices were assessed at Viapath's Tissue Science Mohs laboratory at Guy's Cancer Centre. MATERIAL AND METHODS: A total of 279 samples from 10 anatomically different facial sites...

BACKGROUND: MicroRNAs play a crucial role in the regulation of immune response. We hypothesised roles for serum miR-210 and miR-155 in the diagnosis of rheumatoid arthritis (RA) and relationships with the clinical and laboratory variables including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), anti-cyclic citrullinated peptide (CCP) antibodies, tumour necrosis factor-alpha (TNF-α) and interleukin-1β (IL-1β). METHODS: MiR-210 and miR-155 levels were identified by real-time polymerase chain reaction (PCR)...

BACKGROUND: There is a need to measure antibiotic resistance of Pseudomonas aeruginosa (PA) in cystic fibrosis (CF), either qualitatively or quantitatively, to inform patient management. The aim of this study was to develop a simple method by which resistance can be quantified by calculating a relative resistance index (RRI), and to assess correlation of RRIs with clinical variables. METHODS: In our model, RRIs were calculated based on resistance to aztreonam, ceftazidime, ciprofloxacin, colistin, meropenem, tazocin, temicillin and tobramycin...

BACKGROUND: Circulating miRNAs are potential biomarkers of the pathogenesis of certain diseases and in monitoring therapeutic responses. We hypothesized that serum miR-29 can determine risk of acute cardiac allograft rejection. METHODS: Peripheral vein blood was collected from 50 healthy volunteers and 506 patients during post-transplant surveillance. Serum cardiac troponin I (cTnI) and miR-29 was detected by ELISA and qRT-PCR assay respectively. Rejection risk was defined as International Society of Heart and Lung Transplant score from leukocyte infiltration of an endomyocardial biopsy...

OBJECTIVE: The discovery of specific microRNAs (miRNA) mediates a better understanding of molecular mechanisms, diagnosis and prognosis of complex phenotypes. Synthesis of the RhD blood group involves multiple factors causing variation in the expression of RHD antigens. The mechanism underlying the extremely weak expression of RHD antigen associated with the RHD variant called DEL (D-elute) is incompletely understood. Down-regulation of gene expression through miRNA is a guide to the potential involvement of miRNAs in the DEL blood group...

BACKGROUND: Contrast media is widely used in clinical diagnostic and interventional procedures, but may cause damage to the kidney, that is, contrast-induced nephropathy. This study was to establish a dual-label time-resolved fluorescence immunoassay (TRFIA) for the simultaneous determination of renal function markers cystatin-C (Cys-C) and β2-microglobulin (β2-MG) for the early diagnosis and follow-up surveillance of contrast-induced nephropathy. METHODS: A sandwich immunoassay was used to detect the concentration of Cys-C, and the competitive immunoassay was used to detect the concentration of β2-MG in 50 samples of urine...

BACKGROUND: Non-small cell lung cancer (NSCLC) is a major cause of cancer-related death. Approximately 2-16% of NSCLC patients with wild-type epidermal growth factor receptor (EGFR) harbour anaplastic lymphoma kinase (ALK) mutations. Both EGFR and ALK mutations occur most commonly in Asian patients with NSCLC. As targeted therapy is available for NSCLC patients with these mutations, it is important to establish reliable assays and testing strategies to identify those most likely to benefit from this therapy...

BACKGROUND: Hepatocellular carcinoma (HCC) is a multistage process resulting from various genetic changes. We aimed to determine nuclear phosphoprotein c-Myc and cellular phosphoprotein p53 expression and to evaluate their importance in HCC diagnosis. METHODS: One hundred and twenty chronic hepatitis C (CHC) patients (60 non-HCC CHC patients and 60 HCC patients who had a single small (<5 cm) tumour) were recruited. The gene products of c-Myc and p53 were identified in liver tissues and serum samples using immunostaining, western blot and ELISA...

C J Donaldson, D J Harrington
The impact of warfarin therapy on the functions of extrahepatic vitamin K-dependent proteins (VKDP) is less clearly understood and less widely recognised in clinical practice than that on the hepatic counterparts (clotting factors II, VII, IX and X). Warfarin inhibits osteocalcin, an abundant extrahepatic VKDP involved in the mineralisation and maturation of bone and thus, primarily by this mechanism, may have an adverse effect on bone health. Whilst some studies do link warfarin use to an increase in osteoporosis and fracture risk others have not...

D Sanders, S Fensome-Rimmer, B Woodward
Uncertainty of measurement has become a paramount factor to consider in pathology. In the UK, consideration of uncertainty of measurement is mandatory for medical laboratories who apply to be accredited against ISO15189:2012 via the United Kingdom Accreditation Service. This guideline intends to help those working within diagnostic andrology to better understand the concept of uncertainty, and how it can be applied to semen analysis and post-vasectomy semen analysis. The various areas where uncertainty may exist are identified, and guidance is provided to minimise this uncertainty...
