A visual inspection of the specimen revealed crystals on the bottom of the cup. In December 2013, this patient had tested positive for α-hydroxyalprazolam (an alprazolam metabolite; limit of detection, 10 ng/mL) and methamphetamine. At that time, she explained her positive urine-drug-test ...
in vivo. The ionization state of a drug compound in a specific body compartment can be calculated by considering its dissociation constants relative to the pH in the body compartment of interest, for example, acidic for stomach, basic for intestine, pH 7.4 for plasma, pH 4.5–8.0 ...
existinghydroxyapatitecrystals. Essentially in an insoluble state, these substances are difficult or impossible to remove completely. Bone and tooth mineralization may benefit from appropriate concentrations of F−, but most drug-induced alterations are detrimental. In the case of radioactive metals (e...
Although drug-induced urinary calculi most often complicate high-dose, long-duration drug treatments, there also exist specific patient risk factors in relation to urine pH, urine output and other parameters, which provide a basis for preventive or curative treatment of calculi. Better awareness of ...
Another common form of the drug is crystal methamphetamine, or “crystal meth”, which is clear, chunky crystals resembling ice. Crystal meth is smoked in a manner similar to crack cocaine and became popular in the 1980s. Street names for this form of methamphetamine include “ice”, “...
Ethylene glycol damages the kidney through the formation of calcium oxalate monohydrate crystals in the proxi- mal tubules (~90% of the water from the glomerular filtrate is reabsorbed in the proximal tubules). Such Scientific Reports | 5:12337 | DOI: 10.1038/srep12337 9 www.nature.com/...
Blue crystals of 1 were gathered and cleaned with water and methanol. Yield: 29 mg (~ 45% according to L). Elemental analysis (%): Anal. Calcd for C32H20N6O5Cu: H, 3.19; C, 60.81; N, 13.30. Found: H, 3.18; C, 60.63; N, 13.26. IR (cm−1, KBr pellets): ν (O ...
Then 39 ml of hydrochloric acid was added, the seed crystals were added at 40 to 50° C., and 39 ml of hydrochloric acid was further added dropwise at the same temperature. The solution was cooled to 10° C. the precipitate was filtered and collected to give 65.6 g of 6-fluoro-3-...
Diabetes is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Cancer ...
