Fumarate hydratase (FH) is an enzyme of the tricarboxylic acid (TCA) cycle mutated in hereditary and sporadic cancers. Despite recent advances in understanding its role in tumorigenesis, the effects of FH loss on mitochondrial metabolism are still unclear. Here, we used mouse and human cell lines to assess mitochondrial function of FH-deficient cells. We found that human and mouse FH-deficient ...
Allyl sulfur compounds are the major active constituents found in crushed garlic. Research has revealed that garlic and its lipid- or water-soluble components have many pharmacologic properties; however, studies also demonstrate that heating has a negative influence on these beneficial effects. We recently conducted several studies to investigate the influence of microwave or oven heating on th...
This study investigates the requirements for modeling of acid sulfite pulping with regard to the recovery of cooking chemicals, especially SO2. Such a model has to predict the temporal change of SO2 distribution on solid, liquid and gaseous phase in the digester throughout the whole pulping process, dependent on the pulping parameters: total SO2, free SO2, liquor-towood ratio, temporal temperat...
BACKGROUND Acidithiobacillus caldus (A. caldus) is widely used in bio-leaching. It gains energy and electrons from oxidation of elemental sulfur and reduced inorganic sulfur compounds (RISCs) for carbon dioxide fixation and growth. Genomic analyses suggest that its sulfur oxidation system involves a truncated sulfur oxidation (Sox) system (omitting SoxCD), non-Sox sulfur oxidation system simila...
The presence of mitochondria and related organelles in every studied eukaryote supports the view that mitochondria are essential cellular components. Here, we report the genome sequence of a microbial eukaryote, the oxymonad Monocercomonoides sp., which revealed that this organism lacks all hallmark mitochondrial proteins. Crucially, the mitochondrial iron-sulfur cluster assembly pathway, thoug...
Cultures of the blue-green alga, Aphanocapsa, were grown under iron-limiting conditions and changes in concentration of redox components of the photosynthetic electron transport chain, particularly iron-sulfur centers, were monitored by spectroscopic methods. A moderate iron depletion (1/10 of the normal concentration) had little effect on photosynthetic electron transport reactions and growth....
Using a multifactorial experiment of the plan N = 2(4), influence components air pollution in livestock buildings on moisture absorption film D-11A plastisol mastic was studied by gravimetric method. The corresponding dependence equations are obtained, which show more aggressive effect hydrogen sulfide and sulfur dioxide protective film.
The low sulfur amino acid content of legume seeds restricts their nutritive value for animals. We have investigated the limitations to the accumulation of sulfur amino acids in the storage proteins of narrow leaf lupin (Lupinus angustifolius) seeds. Variation in sulfur supply to lupin plants affected the sulfur amino acid accumulation in the mature seed. However, when sulfur was in abundant sup...
Background: Sulfur mustard gas is a chemical agent that has been used in many wars, especially in Iran-Iraq war. This chemical agent affects many organs including lungs, eyes and skin, causing numerous acute and chronic lesions including erythema and hyperpigmentation, respectively. This study was conducted to evaluate erythema and melanin in subjects with a history of exposure to sulfur ...
