Urine storage

Another controversy surrounds the amount of glycoprotein (mucoprotein) excreted in the urine of adults with and without stones. Some reports showed that there is no difference in the excretion of uromucoids (B2, SI, S2), whereas others found that the excretion of uromucoid-rich material in calcium stone patients was greater than in their healthy counterparts (B3, K2, M5). This controversy may be attributed to different methods of urine storage, because it has been reported that the physical properties of the mucoproteins are altered by freezing (B3). Nevertheless, urine of black persons, who seldom develop stones, contains no uromu-coid (Kl, Ml). 

Iron is, as part of several proteins, such as hemoglobin, essential for vertebrates. The element is not available as ion but mostly as the protein ligands transferrin (transport), lactoferrin (milk), and ferritin (storage), and cytochromes (electron transport) (Alexander 1994). Toxicity due to excessive iron absorption caused by genetic abnormalities exists. For the determination of serum Fe a spectrophoto-metric reference procedure exists. Urine Fe can be determined by graphite furnace (GF)-AAS, and tissue iron by GF-AAS and SS-AAS (Alexander 1994 Herber 1994a). Total Iron Binding Capacity is determined by fuUy saturated transferrin with Fe(III), but is nowadays mostly replaced by immunochemical determination of transferrin and ferritin. 

Control urine should be collected from individuals who have no apparent past history of exposure to the active ingredient. This control urine must be stored frozen until used for field fortification purposes. The urine is then thawed, shaken well, and a certain amount should be aliquoted into a small jar/bottle to use for field fortification. The active ingredient is then added to the urine using a 1-mL volumetric pipet, the solution is shaken well, and the sample is immediately frozen. Occasionally, the fortified sample can be left at room temperature or at some lower temperature in a liquid state to simulate field storage during collection of the urine sample. After leaving the sample at such temperatures for the prescribed length of time, the sample is immediately stored frozen. 

The sinusoids transport both portal and arterial blood to the hepatocytes. The systemic blood delivered to the liver contains nutrients, drugs, and ingested toxins. The liver processes the nutrients (carbohydrates, proteins, lipids, vitamins, and minerals) for either immediate use or for storage, while the drugs and toxins are metabolized through a variety of processes known as first-pass metabolism. The liver also processes metabolic waste products for excretion. In cirrhosis, bilirubin (from the enzymatic breakdown of heme) can accumulate this causes jaundice (yellowing of the skin), scleral icterus (yellowing of the sclera), and tea-colored urine (urinary bilirubin excretion). 

Field fortifications were prepared to check the field/storage stability of the dermal dosimeters, handwashes, and air filters. The field fortifications were prepared using the formulated product undiluted for "high" level spikes and diluted with water (-1 pg/mL chlorpyrifos) for the "low" level field spikes. Field fortification solutions for urine were prepared from a 3,5,6-TCP standard in acetonitrile utilizing an 1.2-pg/mL solution for the "high" field fortifications and an -0.01-ug/mL solution for the "low" level fortifications. 

The remaining liquid flows continuously to a pit outside the house and is pumped in a silo. The fertilizer value is low. Daily removal of faeces and urine promotes as well a better house climate as a lower odour emission in comparison with piggeries with underslat slurry storage. Installing this filtersystem in partly slatted floor houses straw can be used to improve animal comfort, and to reduce heating costs. 

Underslat slurry storage also influences environnement as well inside as outside the piggery because gases are released from the slurry. On the other hand anaerobic digestion processes will be avoid by daily removal and separate storage of faeces and urine. 

It can be concluded that separation and removal of urine and faeces from piggery result in a reduced formation of odour components (5). This might result in a decrease of the precieved odour as compared with a housing system with underslat slurry storage. 

Reduction of the emission of odours by treatment of the slurry is a direct way. On one hand this can partly be done by separate storage of the faeces and the urine. On the other hand by aerobic or anaerobic treatment. 

Other complex, neutral oligosaccharides that have been fractionated by l.c. techniques include those found in human milk > and in urine from patients with lysosomal-storage disorders. ... 

Patients snffering from metabolic disorders such as phenylketonuria (PKU), branched-chain ketoaciduria (maple syrup urine disease, MSUD), nrea and ammonia disorders or glycogen storage disease reqnire formulations manufactured specifically for each disease (Elsas Acosta, 2006). (Appendix 15.1). 

Urine odor of adult males induces and synchronizes estrus cycles in adult female mice (Whitten, 1958). The cycles grow shorter and more regular when a male is nearby. A male shortens cycles of 7-8 days to 4-5 days. Exposure to male urine for 48 hours has the same effect. This phenomenon is known as the Whitten effect. The estrus-inducing activity of male urine is retained even after storage at -4 °C or freeze-drying (Gangrade and Dominic, 1986). This has...
