Rainbow trout eggs were acutely challenged with silver (as AgNO(3)) at different stages of development from fertilization through to hatch in moderately hard water (120 mg CaCO(3) l(-1), 0.70 mM (25 mg l(-1)) Cl(-), 1.3 mg l(-1) DOC, 12.3+/-0.1 degrees C) at measured total silver concentrations of 0.11+/-0.004, 1.55+/-0.15, and 14.15+/-1.52 microg l(-1). Four separate acute challenges were cond...

In Western countries, the legal procurement of cadaveric human organs is everywhere organized as a gi!-exchange. Yet despite this basic similarity, donation rates vary widely, and this fact is o!en overlooked in debates about the merits of gi!versus marketbased systems. I investigate the sources of variation in procurement rates using time-series data from seventeen oecd countries. I focus on t...

BACKGROUND Blood samples for neonatal screening for inborn errors of metabolism are collected and shipped on standardized filter paper cards. Occasionally these samples are contaminated with EDTA, which is often used for anticoagulation. EDTA may interfere with newborn screening tests based on lanthanide fluorescence and thus lead to false-negative or false-positive results. METHODS We used t...

Rhabdomyosarcoma (RMS) is an uncommon neoplasm in adult population. Outcome for adult RMS is poorly documented due to its rarity. Published series have reported worse results for adults compared with children with RMS. Eighteen adult patients with RMS whose age were 17 years and older were treated between 1979 and 2004 and were analyzed retrospectively for treatment outcome. Univariate statisti...

Two-electron reduction of benzoquinone ansamycin (BA) heat shock protein (Hsp) 90 inhibitors by NAD(P)H:quinone oxidoreductase 1 (NQO1) to hydroquinone ansamycins (BAH2s) leads to greater Hsp90 inhibitory activity. BAs can also be metabolized by one-electron reductases and can interact with glutathione, reactions that have been associated with toxicity. Using a series of BAs, we investigated th...

OBJECTIVE While transvaginal polypropylene mesh is increasingly used in the management of pelvic organ prolapse, contraction of the mesh after implantation may cause substantial morbidity. This report defines the clinical entity of vaginal mesh contraction. METHODS This is a case series of women who underwent surgical intervention for the management of symptomatic vaginal mesh contraction in ...

The use of tetramethylammonium hydroxide (T.M.A.H.) in place of potassium hydroxide in the Zimmermann reaction has been investigated. Although various pure steroids have different colour equivalents, a comparison of the results of 17-ketosteroid and 17-hydroxycorticosteroid estimations on a series of urines showed that the differences for the two reagents were only small and may be ignored. Tet...
