Off-line pyrolysis was used to liberate lignin moieties from dung and soil and, after trimethylsilylation, the delta(13)C values of these derivatives were determined ... http://www.med08.com/Off-line-pyrolysis-and-compound-specific-stable-ca-3667.html Randomized clinical trial of laparoscopic total (Nissen) versus posterior partial (Toupet) fundoplication for gastro-oesophageal reflux disease based on preoperative oesophageal manometry (Br J Surg 2008; 95: 57-63). The Editors welcome topical correspondence from readers relating to articles published in the Journal. Responses should be sent electronically ... http://www.med08.com/Randomized-clinical-trial-of-laparoscopic-total-Ni-3666.html Influence of recent vegetation on labile and recalcitrant carbon soil pools in central Queensland, Australia: evidence from thermal analysis-quadrupole mass spectrometry-isotope ratio mass spectrometry. The effect of a recent vegetation change (<100 years) from C(4) grassland to C(3) woodland in central Queensland, Australia, on soil organic ... http://www.med08.com/Influence-of-recent-vegetation-on-labile-and-recal-3665.html Memento of the post-mortem. When the Department of Pathology of the Radboud University Nijmegen Medical Centre in The Netherlands moved from its old to its new premises, the demolition of the marble post-mortem tables was impending, taking with it the Department\'s (physical) memory. To keep the ... http://www.med08.com/Memento-of-the-post-mortem-3664.html Enhancing the understanding of earthworm feeding behaviour via the use of fatty acid delta(13)C values determined by gas chromatography-combustion-isotope ratio mass spectrometry. Litter-dwelling (epigeic) Lumbricus rubellus and soil-dwelling (endogeic) Allolobophora chlorotica earthworms were observed aggregating under C(3) (delta(13)C = -31.3 per thousand; delta(15)N = 10.7 per ... http://www.med08.com/Enhancing-the-understanding-of-earthworm-feeding-b-3663.html Large old trees influence patterns of delta(13)C and delta(15)N in forests. Large old trees are the dominant primary producers of native pine forest, but their influence on spatial patterns of soil properties and potential feedback to tree regeneration in their neighbourhood is poorly understood. We measured ... http://www.med08.com/Large-old-trees-influence-patterns-of-delta13C-and-3662.html Age-adjusted Charlson comorbidity score is associated with treatment decisions and clinical outcomes for patients undergoing radical cystectomy for bladder cancer. BACKGROUND.: By using the age-adjusted Charlson comorbidity index (ACCI), the authors characterized the impact of age and comorbidity on disease progression and overall survival after radical ... http://www.med08.com/Age-adjusted-Charlson-comorbidity-score-is-associa-3661.html Comparative in vivo study of six hydroxyapatite-based bone graft substitutes. Improvement of synthetic bone graft substitutes as suitable alternatives to a patient\'s own bone graft remains a challenge in biomaterials research. Our goal was to answer the question of whether improved osteoinductivity of a material would ... http://www.med08.com/Comparative-in-vivo-study-of-six-hydroxyapatite-ba-3660.html Endoscopic ultrasound and computed tomography in restaging and predicting prognosis after neoadjuvant chemotherapy in patients with locally advanced gastric cancer. BACKGROUND.: The objective of the current study was to assess the staging accuracy and prognostic role of preoperative endoscopic ultrasound (EUS) and computed tomography (CT) in ... http://www.med08.com/Endoscopic-ultrasound-and-computed-tomography-in-r-3659.html Thyroid fine-needle aspiration samples inadequate for reverse transcriptase-polymerase chain reaction analysis. BACKGROUND.: Analysis of different tumor markers by reverse transcriptase-polymerase chain reaction (RT-PCR) in fine-needle aspiration samples of thyroid nodules has been studied with the objective of improving the accuracy of the preoperative diagnosis of thyroid ... http://www.med08.com/Thyroid-fine-needle-aspiration-samples-inadequate--3658.html
