Guidelines for assigning species rank†

Andreas J. Helbig, Alan G. Knox, David T. Parkin, George Sangster, Martin Collinson
2002 Ibis  
Developments in several fields of study (including bio-acoustics and the analysis of DNA) together with reappraisals of the nature of species have impacted significantly on avian taxonomy. The BOU's Taxonomic Subcommittee has developed guidelines for the application of species limits to sympatric, parapatric, allopatric and hybridizing taxa. These are published here to assist researchers understand the rationale behind the committee's taxonomic recommendations relating to the British List.

Running title: Oral glutamine supplementation in cystic fibrosis Word count: 2049 Abstract Rationale: Pulmonary infection and malnutrition in cystic fibrosis are associated with decreased survival. Glutamine has a possible anti-microbial effect, with a specific impact against Pseudomonas aeruginosa. We aimed to test the hypothesis that oral glutamine supplementation (21g/day) for eight weeks in adults with cystic fibrosis would decrease pulmonary inflammation and improve clinical status.

The primary analysis was intention to treat, and the primary outcome was change in induced sputum neutrophils. Results: 39 individuals were recruited and 36 completed the study. Glutamine supplementation had no impact on any of the outcome measures in the intention-to-treat analysis. In the per protocol analysis, glutamine supplementation was associated with an increase in induced sputum neutrophils (p=0.046), total cells (p=0.03), and in Pseudomonas isolation agar colony forming units (p=0.04) compared to placebo. Conclusions: There was no effect of glutamine supplementation on markers of pulmonary inflammation in the intention-to-treat analysis.

Vitamin D - a new treatment for airway remodelling in asthma?

Rachel L Clifford, Alan J Knox
2009 British Journal of Pharmacology  
Increased airway smooth muscle (ASM) mass plays a critical role in chronic asthmatic airway remodelling. ASM cell hypertrophy and hyperplasia are likely to contribute to increased ASM mass and a variety of mitogens induce ASM proliferation in cell culture. Recent recognition of widespread vitamin D deficiency and identification of the vitamin D receptor on many cells has implicated vitamin D as a potential therapeutic target for many disorders including cancer, infection and asthma. In this

They also, perhaps surprisingly, show the glucocorticoid dexamethasone to potentiate mitogen-induced ASM proliferation. Their results begin to elucidate the molecular mechanism(s) utilized by calcitriol to inhibit cell proliferation and suggest hyperphosphorylation of retinoblastoma protein and activation of checkpoint kinase 1 (Chk1) as critical to this process. This study identifies inhibition of ASM proliferation as a cellular effect of vitamin D and supports the hypothesis that vitamin D is a potential treatment for airway remodelling in asthma.

Accelerated extracellular matrix turnover during exacerbations of COPD

2015 Respiratory Research  
Exacerbations of chronic obstructive pulmonary disease (COPD) contribute significantly to disease progression. However, the effect on tissue structure and turnover is not well described. There is an urgent clinical need for biomarkers of disease activity associated with disease progression. Extracellular matrix (ECM) turnover reflects activity in tissues and consequently assessment of ECM turnover may serve as biomarkers of disease activity. We hypothesized that the turnover of lung ECM

Competitive ELISAs measuring circulating protein fragments in serum or plasma assessed the formation and degradation of collagen types III (Pro-C3 and C3M, respectively), IV (P4NP 7S and C4M, respectively), and VI (Pro-C6 and C6M, respectively), and degradation of elastin (ELM7 and EL-NE) and versican (VCANM). Results: Circulating levels of C3M, C4M, C6M, ELM7, and EL-NE were elevated during an exacerbation of COPD as compared to follow-up (all P <0.0001), while VCANM levels were decreased (P <0.0001). Pro-C6 levels were decreased and P4NP 7S levels were elevated during exacerbation (P <0.0001). Pro-C3 levels were unchanged. At time of exacerbation, degradation/formation ratios were increased for collagen types III and VI and decreased for collagen type IV. Conclusions: Exacerbations of COPD resulted in elevated levels of circulating fragments of structural proteins, which may serve as markers of disease activity. This suggests that patients with COPD have accelerated ECM turnover during exacerbations which may be related to disease progression.

Measures of body habitus are associated with lung function in adults with cystic fibrosis: A population-based study

Doug L. Forrester, Alan J. Knox, Alan R. Smyth, Andrew W. Fogarty
2013 Journal of Cystic Fibrosis  
Body habitus differences may explain some of the variation in lung function between individuals with cystic fibrosis (CF). We tested the hypothesis that measures of lean muscle mass and obesity are independently associated with lung function in CF. Methods: Cross-sectional study design using UK CF registry data from 2096 clinically stable adults. Results: Serum creatinine and BMI were positively and independently associated with FEV 1 and FVC. One standard deviation increment in serum

Compared to the reference group of 20-24.9 kg/m 2 , those with a BMI b 20 kg/m 2 had lower FEV 1 with values of − 642 ml (95%CI: − 784 to − 500 ml) for males and − 468 ml (95%CI: − 564 to − 372 ml) for females. Conclusions: Prospective studies and controlled trials are required to ascertain if these associations have therapeutic potential in modifying disease progression.

Direct detection ofN-acylhomoserine lactones in cystic fibrosis sputum

Barry Middleton, Helen C Rodgers, Miguel Cámara, Alan J Knox, Paul Williams, Andrea Hardman
2002 FEMS Microbiology Letters  
Pseudomonas aeruginosa and Burkholderia cepacia cause destructive lung disease in cystic fibrosis (CF) patients. Both pathogens emploỳ quorum sensing', i.e. cell-to-cell communication, via diffusible N-acyl-L-homoserine lactone (AHL) signal molecules, to regulate the production of a number of virulence determinants in vitro. However, to date, evidence that quorum sensing systems are functional and play a role in vivo is lacking. This study presents the first direct evidence for the presence of

AHLs were detected in sputum from patients colonised by P. aeruginosa or B. cepacia but not Staphylococcus aureus. Furthermore, using liquid chromatography-mass spectrometry and thin layer chromatography, we confirmed the presence of N-hexanoylhomoserine lactone and N-(3-oxododecanoyl)homoserine lactone respectively in sputum samples from patients colonised by P. aeruginosa. ß : S 0 3 7 8 -1 0 9 7 ( 0 1 ) 0 0 5 5 6 -0
