Ergosterol reduction impairs mitochondrial DNA maintenance in S. cerevisiae [PDF]
Sterols are essential lipids, involved in many biological processes. In Saccharomyces cerevisiae, the enzymes of the ergosterol biosynthetic pathway (Erg proteins) are localized in different cellular compartments.

Diabetes mellitus and ischemic heart disease. the role of ion channels [PDF]
Diabetes mellitus is one the strongest risk factors for cardiovascular disease and, in particular, for ischemic heart disease (IHD). The pathophysiology of myocardial ischemia in diabetic patients is complex and not fully understood: some diabetic ...

AMP-activated protein kinase inhibits Kv1.5 channel currents of pulmonary arterial myocytes in response to hypoxia and inhibition of mitochondrial oxidative phosphorylation [PDF]
KEY POINTS: Progression of hypoxic pulmonary hypertension is thought to be due, in part, to suppression of voltage‐gated potassium channels (K(v)) in pulmonary arterial smooth muscle by hypoxia, although the precise molecular mechanisms have been unclear.

The uniqueness of the plant mitochondrial potassium channel
The ATP-inhibited Plant Mitochondrial K(+) Channel (PmitoKATP) was discovered about fifteen years ago in Durum Wheat Mitochondria (DWM). PmitoKATP catalyses the electrophoretic K(+) uniport through the inner mitochondrial membrane; moreover, the co-operation between PmitoKATP and K(+)/H(+) antiporter allows such a great operation of a K(+) cycle to ...

Optical Imaging of Lipopolysaccharide-induced Oxidative Stress in Acute Lung Injury from Hyperoxia and Sepsis [PDF]
Reactive oxygen species (ROS) have been implicated in the pathogenesis of many acute and chronic pulmonary disorders such as acute lung injury (ALI) in adults and bronchopulmonary dysplasia (BPD) in premature infants.

A Novel Mitochondrial Potassium Channel in Embryonic Hippocampal Mitochondra [PDF]
Since 1991, when in Nature Inoue and co-workers described the first potassium channel in the inner mitochondrial membrane, ATP-regulated (mitoKATP), four other channels were found. ATP-regulated (mitoKATP), large-conductance calcium activated (mitoBKCa), voltage-dependent (mitoKv1.3), intermediate-conductance calcium-activated potassium channel ...

Do KATP channels open as a prominent and early feature during ischaemia in the Langendorff-perfused rat heart? [PDF]
The objective was to investigate whether myocardial adenosine triphosphate-sensitive K<sup>+</sup> (K<sub>ATP</sub>) channels open during the first 10 min of regional ischaemia in Langendorff-perfused rat hearts.

Cellular excitability and the regulation of functional neuronal identity: from gene expression to neuromodulation [PDF]
The intrinsic properties of a neuron determine the translation of synaptic input to axonal output. It is this input– output relationship that is the heart of all nervous system activity.
