The in vivo sparing of methionine by cysteine in sulfur amino acid requirements in animal models and adult humans.

Ronald O Ball et al.

The Journal of nutrition, 136(6 Suppl), 1682S-1693S (2006-05-17)

Sulfur amino acid metabolism has been receiving increased attention because of the link to chronic diseases such as cardiovascular disease, Alzheimer's disease, and diabetes. In addition, the role of cysteine and optimal intakes for physiological substrates such as glutathione are

Fragmentation reactions of methionine-containing protonated octapeptides and fragment ions therefrom: an energy-resolved study.

Alex G Harrison

Journal of the American Society for Mass Spectrometry, 24(10), 1555-1564 (2013-08-15)

The fragmentation reactions of the MH(+) ions as well as the b7, a7, and a7* ions derived therefrom have been studied in detail for the octapeptides MAAAAAAA, AAMAAAAA, AAAAMAAA, and AAAAAAMA. Ionization was by electrospray using a QqToF mass spectrometer

Correction of the consequences of mitochondrial 3243A>G mutation in the MT-TL1 gene causing the MELAS syndrome by tRNA import into mitochondria.

Olga Z Karicheva et al.

Nucleic acids research, 39(18), 8173-8186 (2011-07-05)

Mutations in human mitochondrial DNA are often associated with incurable human neuromuscular diseases. Among these mutations, an important number have been identified in tRNA genes, including 29 in the gene MT-TL1 coding for the tRNA(Leu(UUR)). The m.3243A>G mutation was described

Planar scintigraphy with 123I/99mTc-sestamibi, 99mTc-sestamibi SPECT/CT, 11C-methionine PET/CT, or selective venous sampling before reoperation of primary hyperparathyroidism?

Camilla Schalin-Jäntti et al.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 54(5), 739-747 (2013-04-05)

All patients with primary hyperparathyroidism should undergo localization studies before reoperation, but it is not known which method is most accurate. The purpose of this prospective study was to compare the performance of planar scintigraphy with (123)I/(99m)Tc-sestamibi, (99m)Tc-sestamibi SPECT (SPECT/CT)

Analysis of metabolic profiles of bile acids in urine using a lipophilic anion exchanger and computerized gas-liquid chromatorgaphy-mass spectrometry.

B Almé et al.

Journal of lipid research, 18(3), 339-362 (1977-05-01)

A method is described for quantitative analysis of bile acids in urine. Urine is acidified and bile acids are extracted on an Amberlite XAD-2 column. Bile salts are converted to acids on an Amberlyst A-15 column and are separated into
