Targeting cytochrome C oxidase in mitochondria with Pt(II)-porphyrins for Photodynamic Therapy [PDF]

open access: yes, 2010
Mitochondria are the power house of living cells, where the synthesis of the chemical "energy currency" adenosine triphosphate (ATP) occurs. Oxidative phosphorylation by a series of membrane protein complexes I to IV, that is, the electron transport chain, is the source of the electrochemical potential difference or proton motive force (PMF) of protons

Glycosylation with O-linked β-N-acetylglucosamine (O-GlcNAc) induces vascular dysfunction via production of superoxide anion/reactive oxygen species [PDF]

open access: yes, 2018
Overproduction of superoxide anion (•O2-) and O-linked β-N-acetylglucosamine (O-GlcNAc)-modification in the vascular system are contributors to endothelial dysfunction.

NADPH Oxidases: Insights into Selected Functions and Mechanisms of Action in Cancer and Stem Cells

open access: yesOxidative Medicine and Cellular Longevity, 2017
NADPH oxidases (NOX) are reactive oxygen species- (ROS-) generating enzymes regulating numerous redox-dependent signaling pathways. NOX are important regulators of cell differentiation, growth, and proliferation and of mechanisms, important for a wide ...

Targeting miRNA‐1a and miRNA‐15b: A Novel Combinatorial Strategy to Drive Adult Cardiac Regeneration

open access: yesAdvanced Science, EarlyView.
The article explores a novel therapeutic strategy for cardiac regeneration by targeting miRNA‐1a and miRNA‐15b. Combinatorial inhibition of miR‐1a and miR‐15b enhances cardiomyocyte proliferation, improves heart function, and reduces fibrosis in myocardial infarction models.

Effects of Iodonium Analogs on Nadph Oxidase 1 in Human Colon Cancer Cells

open access: yesAntioxidants, 2021
Recent studies suggest that of the molecules postulated to function as inhibitors of the NADPH oxidase family of enzymes iodonium analogs known to broadly interfere with flavin dehydrogenase function demonstrate mechanistic validity as NADPH oxidase ...

Silicon-based nanochannel glucose sensor [PDF]

open access: yesAppl. Phys. Lett. 92, 013903 (2008), 2008
Silicon nanochannel biological field effect transistors have been developed for glucose detection. The device is nanofabricated from a silicon-on-insulator wafer with a top-down approach and surface functionalized with glucose oxidase. The differential conductance of silicon nanowires, tuned with source-drain bias voltage, is demonstrated to be ...

Perivascular adipose tissue inflammation in vascular disease [PDF]

open access: yes, 2017
Perivascular adipose tissue (PVAT) plays a critical role in the pathogenesis of cardiovascular disease. In vascular pathologies, perivascular adipose tissue increases in volume and becomes dysfunctional, with altered cellular composition and molecular ...

MMP9High Neutrophils are Critical Mediators of Neutrophil Extracellular Traps Formation and Myocardial Ischemia/Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
During a heart attack, neutrophils rapidly activate and differentiate into a specific subset characterized by high levels of MMP9, a tissue‐damaging enzyme, via the SPI1/CST7 pathway. These neutrophils form harmful net‐like structures (Neutrophil extracellular traps, NETs) that exacerbate heart injury.

Nanowire Growth for Sensor Arrays [PDF]

open access: yes, 2003
A design concept for nanowire-based sensors and arrays is described. The fabrication technique involves electrodeposition to directly grow nanowires between patterned thin film contact electrodes. To prove our concept, we have electrodeposited 1-mm diameter Pd single wires and small arrays.

Nox2 dependent redox-regulation of microglial response to amyloid-β stimulation and microgliosis in aging [PDF]

open access: yes, 2020
Microglia express constitutively a Nox2 enzyme that is involved in neuroinflammation by the generation of reactive oxygen species (ROS). Amyloid β (Aβ) plays a crucial role in Alzheimer’s disease.
