The Current Status of Mesenchymal Stromal Cells: Controversies, Unresolved Issues and Some Promising Solutions to Improve Their Therapeutic Efficacy

open access: yesFrontiers in Cell and Developmental Biology, 2021
Mesenchymal stromal cells (MSCs) currently constitute the most frequently used cell type in advanced therapies with different purposes, most of which are related with inflammatory processes.

Resonance fluorescence from an artificial atom in squeezed vacuum [PDF]

open access: yes, 2016
We present an experimental realization of resonance fluorescence in squeezed vacuum. We strongly couple microwave-frequency squeezed light to a superconducting artificial atom and detect the resulting fluorescence with high resolution enabled by a ...

The Saccharomyces cerevisiae amino acid transporter Lyp1 has a broad substrate spectrum

open access: yesFEBS Letters, EarlyView.
In Saccharomyces cerevisiae, Yeast Amino acid Transporter family members mediate the import of amino acids, ranging from substrate specialists to generalists. Here, we show that the specialist transporter, Lyp1, has a broader substrate spectrum than previously described, with affinity constants spanning from micromolar to millimolar.

Endosomal H2O2 Molecules Act as Signaling Mediators in Akt/PKB Activation

open access: yesAntioxidants
Receptor-mediated endocytosis (RME) is a commonly recognized receptor internalization process of receptor degradation or recycling. However, recent studies have supported that RME is closely related to signal propagation and amplification from the plasma

No Difference in Myosin Kinetics and Spatial Distribution of the Lever Arm in the Left and Right Ventricles of Human Hearts

open access: yesFrontiers in Physiology, 2017
The systemic circulation offers larger resistance to the blood flow than the pulmonary system. Consequently, the left ventricle (LV) must pump blood with more force than the right ventricle (RV). The question arises whether the stronger pumping action of

Porous Si Microparticles Infiltrated with Magnetic Nanospheres

open access: yesNanomaterials, 2020
Porous silicon (pSi) microparticles obtained by porosification of crystalline silicon wafers have unique optical properties that, together with biodegradability, biocompatibility and absence of immunogenicity, are fundamental characteristics to candidate

Relevance of the fluorescence radiation in VHE gamma-ray observations with the Cherenkov technique [PDF]

open access: yesAstroparticle Physics 107 (2019) 26-34, 2018
Atmospheric fluorescence is usually neglected in the reconstruction of the signals registered by Cherenkov telescopes, both IACTs and wide-angle detector arrays. In this paper we quantify the fluorescence contribution to the total light recorded in typical observational configurations.

miRNA‐29 regulates epidermal and mesenchymal functions in skin repair

open access: yesFEBS Letters, EarlyView.
miRNA‐29 inhibits cell‐to‐cell and cell‐to‐matrix adhesion by silencing mRNA targets. Adhesion is controlled by complex interactions between many types of molecules coded by mRNAs. This is crucial for keeping together the layers of the skin and for regenerating the skin after wounding.

Shining light on plant health: Detecting salt stress with a near-infrared fluorescent probe

open access: yesAdvanced Agrochem, 2023
Salt stress remains a significant challenge for crop growth and food security. The development of effective analytical tools for salt stress-related studies is of great importance. Recently, Yang and Yin et al.

Common-path multimodal optical microscopy [PDF]

open access: yes, 2009
We have developed a common-path multimodal optical microscopy system that is capable of using a single optical source and a single camera to image amplitude, phase, and fluorescence features of a biological specimen.
