Electrochemical and Electroconductive Behavior of Silk Fibroin Electrospun Membrane Coated with Gold or Silver Nanoparticles

Membranes, 2022
The surface modification of materials obtained from natural polymers, such as silk fibroin with metal nanoparticles that exhibit intrinsic electrical characteristics, allows the obtaining of biocomposite materials capable of favoring the propagation and ...

Unveiling the value of C-reactive protein as a severity biomarker and the IL4/IL13 pathway as a therapeutic target in recessive dystrophic epidermolysis bullosa: A multiparametric cross-sectional study. [PDF]

Exp Dermatol
Abstract Patients with recessive dystrophic epidermolysis bullosa (RDEB) experience numerous complications, which are exacerbated by inflammatory dysregulation and infection. Understanding the immunological mechanisms is crucial for selecting medications that balance inflammation control and immunocompetence.

The mechanisms underpinning lateral gene transfer between grasses

PLANTS, PEOPLE, PLANET, Volume 5, Issue 5, Page 672-682, September 2023., 2023
Lateral gene transfer (LGT) refers to the transmission of genetic material without sexual reproduction. LGT is widespread in a number of plant species, including grasses. But how these genes of foreign origin got there is presently unknown. In this review, we show that transformation techniques used to genetically modify organisms could occur in the ...

Evaluation of the chemical-enzymatic decellularization method for obtaining extracellular trachea matrixes in a porcine model

Iatreia, 2016
Introduction: Different diseases may affect the trachea and, therefore, the quality of life. Tissue engineering may be a therapeutic alternative for patients with such diseases, using decellularized trachea matrixes seeded with cells from the recipient ...

Forging a symbiosis: transition metal delivery in symbiotic nitrogen fixation

New Phytologist, Volume 239, Issue 6, Page 2113-2125, September 2023., 2023
Summary Symbiotic nitrogen fixation carried out by the interaction between legumes and rhizobia is the main source of nitrogen in natural ecosystems and in sustainable agriculture. For the symbiosis to be viable, nutrient exchange between the partners is essential.

Telomerase RNA gene paralogs in plants – the usual pathway to unusual telomeres

New Phytologist, Volume 239, Issue 6, Page 2353-2366, September 2023., 2023
Summary Telomerase, telomeric DNA and associated proteins together represent a complex, finely tuned and functionally conserved mechanism that ensures genome integrity by protecting and maintaining chromosome ends. Changes in its components can threaten an organism's viability.

Natural variation in Avr3D1 from Zymoseptoria sp. contributes to quantitative gene‐for‐gene resistance and to host specificity

New Phytologist, Volume 238, Issue 4, Page 1562-1577, May 2023., 2023
Summary Successful host colonization by plant pathogens requires the circumvention of host defense responses, frequently through sequence modifications in secreted pathogen proteins known as avirulence factors (Avrs). Although Avr sequences are often polymorphic, the contribution of these polymorphisms to virulence diversity in natural pathogen ...
