The human mitochondrial genome (mtDNA) encodes 22 tRNAs (mt-tRNAs) that are necessary for the intraorganellar translation of the 13 mtDNA-encoded subunits of the mitochondrial respiratory chain complexes. Maturation of mt-tRNAs involves 5' and 3' nucleolytic excision from precursor RNAs, as well as extensive post-transcriptional modifications. Recent data suggest that over 7% of all mt-tRNA res...

Metallothioneins are encoded by a family of genes that are induced by inorganic mercury. Despite the well-characterized acute response of metallothionein (MT) genes in the kidneys and liver after a single exposure to inorganic mercury, relatively little is known about the activity of these genes and the content of MT protein during prolonged periods after exposure. Rats treated with inorganic m...

We have carried out precision magnetic measurements utilizing a magnetic-resonance technique, aiming for improving the magnetic-field standard below 100 mT. The standard for measuring dc magnetic flux density is intended to cover the range from 10 mT to 100 mT, with an uncertainty (k = 2) ranging from 4 mT/T to 10 mT/T.

Although the induced synthesis of metallothionein (MT) after exposure to certain metals has been known for some time, there is little information on the quantitation of MT in various tissues. In this study, tissue MT concentrations were measured by a modified Cd-saturation method in tissues of adult male rats after injection of different metal salts. There were differences in tissue levels of M...

There is a strong tendency among MT researchers to emphasize paradigmatic differences in MT approaches. This often leads to energetic criticism of competing systems, but obscures the fact that many techniques developed within a particular paradigm can improve the quality of MT systems in general. In this paper we show how practical MT development must move beyond dogmatic dismissal of differing...

Caenorhabditis elegans adapted for survival in high concentrations of Cd(II) express a heavy metal binding protein designated C. elegans metallothionein-like protein or MT-Ce. This protein was purified to homogeneity and characterized. MT-Ce binds 6 mol of Cd(II)/mol protein. The sequence of 39 amino-terminal residues in MT-Ce was determined. A radiolabeled 41-mer oligonucleotide, designed from...

Brebes Regency has a potato-producing center, precisely in Paguyangan Sub-District. The potato variety is type of granola. Potato price that tends to fluctuate, and the cost production relatively high, causing interest farmers growing potatoes decline. research aimed determine income received by District. analytical method used farm formula fixed costs, variable revenues, income. This was held ...

Metallothioneins (MTs) have been implicated in the intracellular regulation of essential metals in eukaryotic cells, and increased expression of MT genes has been demonstrated during the growth and proliferation of cells. To explore the expression of MT in somatic cells undergoing growth (hypertrophy) in the kidney in situ, we measured the rates of transcription of the genes for MT-1 and MT-2, ...
