Oxidative Stress Response Mechanisms Sustain the Antibacterial and Antioxidant Activity of .

The development of new natural antibiotics is considered as the heart of several investigations in the nutraceutical field. In this work, leaves of L. treated by tropospheric ozone (O) and nitrogen (N) deposition, exhibited a clear antimicrobial efficacy against five multi-drug resistant (MDR) bacterial strains (two gram-positive and three gram-negative).

All natural mussel-inspired bioadhesives from soy proteins and plant derived polyphenols with marked water-resistance and favourable antibacterial profile for wound treatment applications.

Hypothesis: Implementation of tissue adhesives from natural sources endowed with good mechanical properties and underwater resistance still represents a challenging research goal. Inspired by the extraordinary wet adhesion properties of mussel byssus proteins resulting from interaction of catechol and amino residues, hydrogels from soy protein isolate (SPI) and selected polyphenols i.e.

From Proton to Boron: The Lewis Analogs of Protonated Brønsted Super Acids.

Isolation and characterization of highly reactive intermediates are crucial to understand the nature of chemical reactivity. Accordingly, the reactivity of weakly coordinating anions (WCA), usually used to stabilized cationic super electrophiles are of fundamental interest. When a variety of WCA are known to form stable σ-complexes with a proton, inducing Brønsted super acidity, bis-coordinated weak-coordinated anions are much more elusive and considered as long-sought reactive species.

Cardiac Differentiation Promotes Focal Adhesions Assembly through Vinculin Recruitment.

Cells of the cardiovascular system are physiologically exposed to a variety of mechanical forces fundamental for both cardiac development and functions. In this context, forces generated by actomyosin networks and those transmitted through focal adhesion (FA) complexes represent the key regulators of cellular behaviors in terms of cytoskeleton dynamism, cell adhesion, migration, differentiation, and tissue organization. In this study, we investigated the involvement of FAs on cardiomyocyte differentiation.
