introduction and objective: zinc as the second trace element of the human body plays an important role in numerous functions. a large number of research studies have showed serum zinc deficiency and excess urinary excretion in patients with major beta thalassemia, but few studies revealed excess urinary zinc excretion in minor beta thalassemia and no study investigated serum zinc levels in this...

Clenbuterol is a well-known growth promoter, illegally used in farm animals, especially in cattle. Samples collected for the screening of beta(2)-agonist residues in Portuguese Azores Islands must travel through all the nine islands until they reach Azores Central Laboratory. If any suspicious sample is detected, it must be further transported to the National Reference Laboratory in Lisbon for ...

The presence of white spots in the kidneys of cattle at slaughter (so-called white-spotted kidneys) can be an indication of infection with Leptospira, a spirochaete of public health concern because it causes zoonotic disease. In this study, 24 kidneys of 180 slaughtered cows (13.3%) showed focal to multifocal white spots at inspection. These kidneys, together with matching urine (n = 18) an...

Data from an experiment utilizing 78 individually fed heifers (407 ± 32 kg) were used to determine relationships of G: F and residual feed intake (RFI) to metabolizable protein balance (MPB), purine derivative excretion to creatinine excretion (PD:C) and 3-methyl histidine excretion to creatinine excretion(3MH:C). Heifers were fed steam-flaked corn based diets containing either 0 (NEG) or 1.5% ...

In February and May 1986, weekly samples of whole pasteurised milk were collected from the 24 dairies supplying seven British towns. A random sample of 96 women aged 25-64 was drawn from general practitioners' lists in each town, and catch specimens of early morning urine were collected by post from 194 subjects in February and from 186 subjects in May. Median milk iodine concentration was sign...

Recently, phosphorus (P) has become a material that is the focus of many countries, including EU, due to its scarcity. EU countries significantly depend on P export/import lack extraction and deposits. In this paper, an economic analysis management in Slovakia as source for responsible sustainable exploitation reuse presented based available sources, whether traditional (P rock mining), recover...

BACKGROUND Variation in different urinary measurements for evaluation of iodine status is of concern to clinicians and researchers. OBJECTIVE This study evaluated variations between urine iodine concentration (UIC), spot and 24-h urine sample creatinine concentrations, and 24-h urine iodine excretion (24-h UIE) in repeated samples from school-age children. METHODS Urine samples (24 h and mo...
