It was found that the UV light intensity, the number of illumination cycles, the choice of photoinitiator, and the thiol crosslinker play an important part in the glove quality. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012″
“Background. Low-molecular-weight heparins (LMWHs) are an alternative

to unfractionated heparin (UFH) for anticoagulation during hemodialysis (HD). We performed a prospective randomized crossover study of the effect of enoxaparin, nadroparin, and dalteparin on some hemostatic factors, including tissue factor pathway inhibitor (TFPI), in patients with maintenance HD. Methods. Plasma levels (immunoassays) of total TFPI, platelet-derived growth factor-AB (PDGF-AB), and prothrombin fragment 1 + 2 (PF 1 + 2) were evaluated pre-HD, after 10 (T10) and 180 (T180) minutes YM155 of HD in 21 patients, who completed a 3-period (for 2 months each) crossover study in 6 groups (Latin-square design). Results. The baseline TFPI, PDGF-AB, and PF 1 + 2 levels were comparable under all LMWH treatments. Tissue

factor pathway inhibitor selleck inhibitor levels, compared with the baseline, significantly increased (all P < 10(-4)), whereas PDGF-AB levels remained stable at each interval during enoxaparin, nadroparin, and dalteparin anticoagulated HD. Interestingly, TFPI increment at T10 was the highest, dose-dependent, and accompanied by PF 1 + 2 decrease under enoxaparin administration. Conclusion. The switch from enoxaparin to nadroparin and dalteparin used as anticoagulants had no long-term effect on the baseline total TFPI and PF 1 + 2 levels in chronically HD patients. Only short-term, overdialytic differences were noticed, indicating a single bolus of enoxaparin (0.75 mg/kg) as the most potent stimulus for endothelial TFPI”
“Tumours of the clivus are rare and metastases involving this area have been previously described only as single case reports or included in series with other skull base tumours. Here, we describe seven such examples and review the pertinent literature.

Clinical, radiological and follow-up data of

patients who had undergone surgery for clivus tumours at our Institution between January 1995 and December 2007 were retrospectively collected. A literature review was performed using PubMed.

Of 46 patients who underwent surgery for clivus bone A-1155463 price tumours, seven proved to harbour a metastasis. This figure represents 0.18% and 0.42% respectively of intracranial and skull base tumours which were treated in our Institution in the study period. The primary tumours associated were lung adenocarcinoma (n = 2), prostate carcinoma (n = 2), skin melanoma (n = 1), hepatocarcinoma (n = 1) and lung squamous cell carcinoma (n = 1). All patients presented with a sixth nerve palsy as the symptom. Histopathology was obtained via a trans-sphenoidal biopsy. In spite of radiotherapy and chemotherapy, the mean survival was 12 months.
