Under normal circumstances, two members of the urobilinogen group have been identified in human feces and urine, both of which are determined quantitatively in the routine urobilinogen procedure (1). Of these, stercobilinogen predominates, while mesobilirubinogen occurs only in small amounts except during excessive hemolysis, when it has been present in sufficient quantity to permit crystalliza...

Evidence has been presented to show that in rat liver preparations serine is probably condensed with homocysteine to yield cystathionine which is then cleaved to cysteine (1). Employing N16-labeled serine, Stetten found the isotopic nitrogen in the cystine isolated from rat tissues (2). These data served as the basis for the suggestion that the carbons of cystine originate from those of serine....

Recent interest in tryptophan metabolism has been stimulated by evidence that tryptophan is a precursor of nicotinic acid in mammals (1) as well as in Neurospora CTUSSU (2). The formation of kynurenine, kynurenic acid, and xanthurenic acid from tryptophan has been demonstrated by numerous experiments (3-5) and has been confirmed by isotope technique in the case of kynurenine and kynurenic acid ...

Several markers have been studied for their ability to make the CNS infiltration diagnosis earlier and more precise; previous studies showed that CSF ferritin concentrations were higher in patients with malignant invasion of CNS. The objective was to determine the importance of CSF ferritin as a biomarker for the diagnosis of CNS neoplastic infiltration. This study is based on 93 CSF samples, d...

In Sweden, drainage and the construction of water infrastructure have influenced agriculture in last few centuries both positively negatively. Recently, a trend has set where wetlands are constructed to retain water, reduce nutrients enhance biodiversity. This study aimed use remote sensing techniques landscape retention over time. this pilot study, structures Gotland (57°28′35.0′′N18°29′ 13.9′...
