Altered Oxygen Utilisation in Rat Left Ventricle and Soleus after 14 Days, but Not 2 Days, of Environmental Hypoxia. [PDF]
The effects of environmental hypoxia on cardiac and skeletal muscle metabolism are dependent on the duration and severity of hypoxic exposure, though factors which dictate the nature of the metabolic response to hypoxia are poorly understood.

The mode of action of isocyanide in three aquatic organisms, Balanus amphitrite, Bugula neritina and Danio rerio. [PDF]
Isocyanide is a potential antifouling compound in marine environments. In this study, we investigated its mode of action in three aquatic organisms. Two of them, the bryozoan Bugula neritina and the barnacle Balanus amphitrite, are major marine fouling ...

Portasomes as Coupling Factors in Active Ion Transport and Oxidative Phosphorylation [PDF]
SYNOPSIS. We propose that particles, 7–15 nm in diameter, observed on the apical plasma membranes of cation transporting cells of insect midgut, salivary glands, and Malpighian tubules are modified F1-F coupling complexes such as those found on phosphorylating membranes of mitochondria, chloroplasts, and bacteria. We suggest the generic term, portasome,

Correlation of structure and function in the oxidative phosphorylation system of submitochondrial particles [PDF]
1. After the centrifugation of sonicated heavy beef heart mitochondria at 75, 000 × g for 10 minutes, the supernatant was centrifuged at 144, 000 × g for 30 minutes. The residue was revealed being composed of vesicular inner membrane fragments (

Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...

Preparation of Neurospora crassa mitochondria [PDF]
The fungus Neurospora crassa represents a eukaryotic cell with high biosynthetic activities. Cell mass doubles in 2-4 hr during expone ntial growth , even in simple salt media with sucrose as the sole carbon source. The microorgani sm forms a mycelium of

Mutations in valosin-containing protein (VCP) decrease ADP/ATP translocation across the mitochondrial membrane and impair energy metabolism in human neurons [PDF]
Mutations in the gene encoding valosin-containing protein (VCP) lead to multisystem proteinopathies including frontotemporal dementia. We have previously shown that patient-derived VCP mutant fibroblasts exhibit lower mitochondrial membrane potential ...

Isolation of oligomycin-sensitive adenosine triphosphatase from beef heart mitochondria and analysis of its fine structure [PDF]
1. An oligomycin -sensitive ATPase was isolated and partially purified from beef heart mitochondria. The specific activity of ATPase sensitive to oligomycin of the fraction was five to eight times that of aged mitochondrial or of DNP-induced ...
