Separation/isolation of subcellular species, such as mitochondria, lysosomes, peroxisomes, Golgi apparatus, and others, from cells is important for gaining an understanding of the cellular functions performed by specific organelles. This study introduces a high speed, semipreparative scale, biocompatible size sorting method for the isolation of subcellular organelle species from homogenate mixt...

T'b is comilitmication emphasizes the nieed for conltin1uouts conitrol of pH when macerating acidic plant tissues for the l)url)ose of isolating tightly coupled mitochondria. A useful device for such control is described. Mitochonidria capable of oxidative but not pl)osphorylative activity have been isolated fromli apple fruits wlhenl either alkaline homogeniates (5) or l)oIyvinylpyrrolidone (P...

Previous studies demonstrated that CSE induces oxidative stress and its consequences on isolated mitochondria obtained from lung, heart and brain which may provide insight into the role of CSE in human health and disease. The present study was carried out to further characterize and compare toxic effect of CSE extract on isolated mitochondria obtained from either a directly contacting tissue (i...

Natural products isolated from plant sources are well known for their pharmacological potential in diversity of disease treatments such as inflammatory or cancer conditions. Mango (Mangifera indica L.) and Juglans regia are thought to be rich of functional phytochemicals. To elucidate the anticancer activity of Juglans regia (JR) and Mangifera indica L (MI) aqueous extract were investigated on ...

Intact mitochondria have been successfully prepared from body tissues from the termites Nasutitermes walkeri and Coptotermes formosanus. This is the first report of the successful isolation of mitochondria from termites (Isoptera: Termitidae). Using an oxygen electrode, oxygen consumption by the mitochondria during the oxidation of various respiratory substrates was determined and their propert...

Mitochondria are responsible for supplying of most of the cell's energy via oxidative phosphorylation. However, mitochondria also can be deleterious for a cell because they are the primary source of reactive oxygen species, which are generated as a byproduct of respiration. Accumulation of mitochondrial and cellular oxidative damage leads to diverse pathologies. Thus, it is important to maintai...

In order to establish a method of obtaining rat gingival mitochondria (Mt), Mt fractions were prepared in various combinations of homogenizing time with collagenase concentration. Rat gingival tissues were excised, minced, treated with collagenase, homogenized, and subjected to differential centrifugation rates. Both the respiratory control ratio (RCR) and adenosine diphosphate/oxygen (ADP/O) r...

Morphologically and functionally intact mitochondria were isolated from the porcine pancreas using a conventional, differential centrifugation method. The homogenate of the porcine pancreas made in a medium containing 0.25 M sucrose, 10 mM Tris-Cl, pH 7.4, 0.5% bovine serum albumin and 1 mM EDTA, in the presence or in the absence of dibucaine and trypsin inhibitor, was centrifuged for 10 min at...

The tricarboxylate transporter was solubilized from pea (Pisum sativum) mitochondria with Triton X-114, partially purified over a hydroxylapatite column, and reconstituted in phospholipid vesicles. The proteoliposomes exchanged external [(14)C]citrate for internal citrate or malate but not for preloaded d,l-isocitrate. Similarly, although external malate, succinate, and citrate competed with [(...
