05).\n\nConclusions: Testicular volume, which is a parameter of spermatogenesis, is impaired in patients on hemodialysis and oxidative stress is considered to be involved in the process. Serum ferritin is a useful parameter for predicting

oxidative stress in the testis.”
“Cerebrospinal fluid (CSF) is being analyzed for the diagnosis of a variety of neurological diseases. Among the methods employed, metabolomics and proteomics are JQ1 increasingly gaining popularity. At present, sensitivity and, in particular, specificity are limited in CSF metabolomics by nuclear magnetic resonance (NMR) spectroscopy. Nonetheless, progress is being made by studying more and more well-defined and homogeneous patient cohorts. This review starts off with a brief overview of classical CSF analysis in multiple sclerosis (MS), followed by a description of NMR spectroscopy in general metabolic CSF analysis. The subsequent sections focus on metabolomic profiling of CSF by NMR spectroscopy in MS and other neurological disorders. Currently existing results Screening Library screening are reviewed and compared, and the potential and limits of this approach are discussed. In addition, several methodological questions are addressed, and the prospects for future developments are briefly outlined.”
“BACKGROUND\n\nAlthough tonometry-based

devices have been applied in several population studies and clinical trials, the agreement between them remains unclear.\n\nMETHODS\n\nCarotid systolic blood pressure (SBP) and augmentation index (AI) were randomly measured from 3 devices, SphygmoCor, PulsePen, and A-Pulse, in 66 consecutive patients from our ambulatory cardiovascular department. The study contains 2 phases: in Study 1, SphygmoCor and PulsePen were performed on each participant by 2 experienced physicians (n = 66); in Study 2, A-Pulse was added after the measurements of SphygmoCor and PulsePen and performed OSI 744 by another technician on the last 34 patients.\n\nRESULTS\n\nCarotid SBP and AI measured by the 3 devices were strongly correlated (R >= 0.78; P < 0.001), but

with significant discrepancies. Specifically, in 66 participants of Study 1, PulsePen estimated higher carotid SBP and AI by 5 mm Hg and 5.7%, respectively, than SphygmoCor. In 34 patients of Study 2, A-Pulse estimated higher central SBP by 3.7 mm Hg than SphygmoCor, and lower central SBP by 5.7 mm Hg than PulsePen. However, no significant difference in interclass comparison was detected between the 3 devices (P >= 0.26). Furthermore, slopes of correlation plots of parameters between SphygmoCor and PulsePen were not significantly different from 1 (P >= 0.09), but were different in the case of A-Pulse (P <= 0.004).\n\nCONCLUSIONS\n\nTonometry-based devices were not consistent in measurements of central BP and wave reflections in clinical practice, with considerable and significant differences among them.
