Electronic address:
The capacity of mature adipocytes to de-differentiate into fibroblast-like cells has been demonstrated in vitro and a few, rather specific in vivo conditions. A detailed comparison between de-differentiated fat (DFAT) cells and adipose stem and progenitor cells (ASPCs) from different adipose depots is yet to be conducted. Moreover, whether de-differentiation of mature adipocytes from classical subcutaneous and visceral depots occurs under physiological conditions remains unknown.

Rutin, a promising bioactive hydrophobic compound, suffers from poor physicochemical stability, resulting in low bioavailability. Herein, we used positively charged chitosan and negatively charged fucoidan as biopolymers coating rutin-nanoliposome (RNL) via electrostatic layer-by-layer self-assembly approach to prepare fucoidan/chitosan-coated rutin-nanoliposome (FC-RNL). The FC-RNL exhibited the encapsulation efficiency of 77.

The activation of astrocytes in the injured lesion induces the progression of spinal cord injury (SCI). However, adverse side-effects during systemic administration have limited applications. Exosomes (Exos) are an emerging clinical treatment method that exerts anti-inflammatory effects by reducing pro-inflammatory factors and promoting functional recovery.

Plants control their stomatal apertures to optimize carbon dioxide uptake and water loss. Stomata open in response to light through the phosphorylation of the penultimate residue, Thr, of plasma membrane (PM) H+-ATPase in guard cells. Stomata close in response to drought and the phytohormone abscisic acid (ABA), and ABA suppresses the light-induced activation of PM H+-ATPase.

Purpose: infection is the most common pathogen in burn wound infections, causing delayed wound healing and progression to chronic wounds. Therefore, there is an urgent need to develop antimicrobial agents that can promote wound healing for effectively treating infected wounds.
Patients And Methods: Using magnetic stirring and ultrasound to synthesize Apt-pM@UCNPmSiO-Cur-CAZ.
