OBJECTIVE Serum YKL-40 plays roles in inflammatory and vascular processes. Our aim was to evaluate serum YKL-40 levels in patients with ankylosing spondylitis (AS) and to investigate their potential relationship with arterial stiffness based on carotid-femoral pulse wave velocity (CF-PWV). METHODS Forty-three patients with AS and 41 healthy controls with no history or current signs of cardiov...

Automated computerized scoring systems (ACSSs) are being increasingly used to analyze text in many educational settings. Nevertheless, the impact of misspelled words (MSW) on scoring accuracy remains to be investigated in many domains, particularly jargon-rich disciplines such as the life sciences. Empirical studies confirm that MSW are a pervasive feature of human-generated text and that despi...

BACKGROUND AND AIMS Cystic Fibrosis (CF) lung disease is characterized by progressively declining lung function and represents a major factor contributing to the high morbidity and mortality associated with CF. However, apart from spirometry, respiratory disease surrogate markers reliably indicating CF lung disease and the occurrence of pulmonary exacerbations (PEx) are still lacking. Within th...

Mr. Don Walter should be commended for his technical paper dealing with the real-world problems of preparing anaerobic digester feeds from a difficult raw material, municipal solid waste (MSW). The information presented in the paper is not readily available in the published litera­ ture, and will be valuable to engineers interested in MSW processing and digestion. The author discusses some of t...

The effect of ribose-induced Maillard reaction on the physical and mechanical properties of gelatin films was investigated. Bovine gelatin solution (5 g/100 mL) containing glycerol and sorbitol (1:1) was mixed with 20% (R20), 40% ribose (R40), or 40% sucrose (S40) (weight % is based on gelatin dry weight) followed by heating (90oC, 2 h) and oven drying to produce dried gelatin films. R20 and R4...

Small intestinal bacterial overgrowth (SIBO) may play an important role in the gastrointestinal complications of cystic fibrosis (CF). This work explored two potential factors in development of SIBO in the CF (cftr(tm1UNC)) mouse: impaired Paneth cell innate defenses and altered gastrointestinal motility. Postnatal differentiation of Paneth cells was followed by Defcr, Lyzs, and Ang4 gene expre...

Activation of cell death in mammals can be assessed by an increase of an amount of cell-free DNA (cf-DNA) in urine or plasma. We investigated the excretion of cf nuclear DNA (nDNA) and cf mitochondrial DNA (mtDNA) in the urine of rats 3 and 24 months in age after X-irradiation and metformin administration. Analyses showed that prior to treatment, the amount of cf-nDNA was 40% higher and cf-mtDN...
