C M P0 4 The arrowed objects are tyrosine crystals. Tyrosine crystals are rare and their presence in urine is always abnormal. They form clusters of silky needle-like structures that are colorless, or black on focusing. Tyrosine crystals are found in acid urine, increase after refrigeration, and are insoluble in alcohol or ether. They are soluble in dilute hydrochloric acid, alkali and relative...

We describe a simple, rapid chromatographic method for separating and quantitatively determining sulfisoxazole and its N4-acetyl metabolite in plasma and urine. A 100-zL sample of plasma or urine is combined with 200 tL of a solution containing 12 mg/L of the internal standard, Nt acetylsulfamethoxazole, in absolute methanol and centrifuged to obtain a clear supernatant solution. This solution ...

The processes of decomposition that the body will have after time death are peculiar and complex. swells expels gases fluids, flesh decays. It also attracts many insects scavengers. We know these fluids nutrients for vegetation, if is inhumed in subsurface, they allow a rapid crop growth remote sensors can mark. During forensic investigations, mapping fluid migration subsurface help reconstruct...

(Pp. ix + 212; figs. 6. tables 29. 16s.) London and Edinburgh: E. & S. Livingstone, 1955. SUFFICIENT knowledge of the physiological mechanisms which regulate the volumes and composition of the body fluids now exists to permit a logical approach to therapy of fluid and electrolyte imbalance. This book aims to set out, in reasonable compass, the aspects of this subject of particular interest to s...

In vitro dissolution behaviors of CaTiO3 thin films deposited with ion beam assisted deposition (IBAD) and sputter-deposition techniques were investigated using Rutherford backscattering spectrometry (RBS) and Auger electron spectroscopy (AES). In vitro test was carried out by immersion in a simulated body fluid at 37 C for 5, 24, and 888 h. The dissolution of titanium ions from CaTiO3 film was...

In vitro bioaccessibility (IVBA) studies were carried out on samples of mercury (Hg) mine-waste calcine (roasted Hg ore) by leaching with simulated human body fluids. The objective was to estimate potential human exposure to Hg due to inhalation of airborne calcine particulates and hand-to-mouth ingestion of Hg-bearing calcines. Mine waste calcines collected from Hg mines at Almaden, Spain, and...

Composite bone cements were formulated with bioactive glass (MgO--SiO(2)--3CaO. P(2)O(5)) as the filler and hydrophilic matrix. The matrix was composed of a starch/cellulose acetate blend (SCA) as the solid component and a mixture of methylmethacrylate/acrylic acid (MMA/AA) as the liquid component. The curing parameters, mechanical properties, and bioactive behavior of these composite cements w...
