Evolving Platinum‐Copper Nanostructures for Enhanced Photothermal Therapy and Controlled Copper Release in Cancer Therapy

Advanced Functional Materials, EarlyView.
Platinum‐Copper bimetallic nanoparticles may evolve depending on their synthesis under tumor microenvironment conditions and play a dual role as chemotherapeutic agents after releasing Cu ions and as near infrared photothermal agents with the Pt‐rich remaining frames.

Effects of salinity on the transcriptome of growing maize leaf cells point at cell-age specificity in the involvement of the antioxidative response in cell growth restriction [PDF]

, 2013
BACKGROUND: Salinity inhibits growth and development of most plants. The response to salinity is complex and varies between plant organs and stages of development. It involves challenges of ion toxicities and deficiencies as well as osmotic and oxidative

Differential Compartmentalization of Enzymatic Reactions for Lactate Signaling Across Protocells

Advanced Functional Materials, EarlyView.
Two populations of protocells consisting of giant unilamellar vesicles containing active species and distinct artificial organelles are competent of collective behavior by mimicking production, intercellular communication, and detection of the bioinspired signal molecule lactate. Enzymatic cascade reactions within artificial organelles demonstrate that

Neuroprotective Effect of Aqueous Extract of Berberis vulgaris L. in a Model of Parkinson’s Disease in Rat

Journal of Medicinal Plants, 2010
Background: Parkinson’s disease is a neurodegenerative disease of dopaminergic neurons in substancia nigra. Superoxides formation is one of the main etiologies of the disease, and angiotensin converting enzyme inhibitors (ACEIs) are able to suppress ...

Visible-light-driven BiOI and GO/BiOI photocatalysts for organic pollutants degradation and hydrogen production using low power sources

Frontiers in Nanotechnology
BiOI and (3 wt%)GO/BiOI visible-light-driven photocatalysts were obtained by a one-pot solvothermal method and successfully applied to the degradation of single and binary dye solutions of rhodamine B (RhB) and methylene blue (MB) and H2 production using

The Endothelial Tyrosine Phosphatase SHP-1 Plays an Important Role for Vascular Haemostasis in TNFα-Induced Inflammation In Vivo

Mediators of Inflammation, 2013
Introduction. Inflammation and endothelium-derived superoxides are important pathomechanisms in atherothrombotic diseases. We could previously show that the tyrosine phosphatase SHP-1 acts as a negative regulator in endothelial superoxide production.

Controlled Aggregation of Pyrene‐Based Supramolecular Nanostructures for Light‐Driven Switchable H2 or H2O2 Production

Advanced Functional Materials, EarlyView.
This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.

Effects of Methotrexate on IL-6alphar, VCAM-1 and NF Kappa B Expression in a Rat Model of Metabolic Syndrome [PDF]

, 2016
Background: In this study, we used Methotrexate (Mtx) to examine the role of immunomodulation on the activation of IL-6 and VCAM-1, which could generate a microenvironment that supports cardiovascular remodelling.Methods: Male WKY and SHR rats were ...
