Promoting Treg Polarization‐Mediated Anti‐Scar and Appendage Regeneration in Wound Healing

Advanced Science, EarlyView.
This study develops a PLGA@LA‐BMP4‐PG bilayer scaffold to address scar formation and appendage loss in skin repair. The piezoelectric PLA layer enhances cell migration via electric fields, while GelMA delivers LA promoting Tregs polarization and BMP4 inhibiting FBs differentiation.

Gαi1/3 Is a Novel Regulatory Target for RANKL Signal Transduction and Osteoporosis

Advanced Science, EarlyView.
ABSTRACT Osteoporosis, characterized by progressive bone loss and increased fracture risk, is a growing concern as the population ages. Current treatments, though advanced, remain limited, underscoring the necessity for novel therapeutic targets. Recent studies have shown that the immune system plays a key role in osteoporosis, with osteoclasts driving

Dynamics of skew tent maps

Dynamics of skew tent maps
This paper deals with the dynamical properties of so-called skew tent maps defined by \[ f_{a,b}(x)= \begin{cases} ax+1, &x\leq 0,\\ -bx+1, &x\geq 0,\end{cases} \tag{1} \] \((a,b)\in D:= \{(a,b)\mid a>0\), \(b>1\), \(a+b\geq ab\}\). Here the authors give the relation between \(*\)-product for a kneading sequence and renormalization.

Amyloid β Instigates Cardiac Neurotrophic Signaling Impairment, Driving Alzheimer's Associated Heart Disease

Advanced Science, EarlyView.
This research identified cardiac amyloid pathology, neurotrophic factor depletion, and reduced myocardial nerve function in a transgenic model of cerebral amyloidosis (Tg2576), Aβ‐challenged cardiomyocytes, and in human AD heart tissue. These findings carry significant diagnostic and therapeutic implications, emphasizing the role of neuro‐signaling ...

Parameter Estimation of a Class One-Dimensional Discrete Chaotic System

Discrete Dynamics in Nature and Society, 2011
It is of vital importance to exactly estimate the unknown parameters of chaotic systems in chaos control and synchronization. In this paper, we present a method for estimating one-dimensional discrete chaotic system based on mean value method (MVM).

Unraveling the Morphological and Functional Maturation Mechanisms Underlying Human Neural Development Using iPSCs‐Derived Neuronal Model

Advanced Science, EarlyView.
Using human induced pluripotent stem cells (hiPSCs)‐derived neuronal model, Tian and colleagues reveal that voltage‐gated calcium channels Cav1.2 and Cav1.3, and their mediated calcium ion influx, are essential for early morphogenesis of human neuronal development, while ECEL1 underlies human neuronal functional developmental maturation through CALM3 ...

Anti‐Apoptotic and Neurite‐Protective Nanomedicine Augments Embryonic Stem Cells‐Derived Retinal Ganglion Cell Transplantation in Glaucoma Recovery

Advanced Science, EarlyView.
Lithium‐epigallocatechin gallate nanoparticles (Li‐EGCG NPs) are co‐transplanted with embryonic stem cell‐derived retinal ganglion cells (ESC‐RGCs) to enhance cell survival and therapeutic efficacy in an acute pathological glaucomatous injury model. This synergistic approach protects RGC cells, preserves retinal structure and improves visual function ...

Fractal tiles induced by tent maps

Discrete and Continuous Dynamical Systems
In the present article, we deal with geometrical objects induced by the tent maps associated with special Pisot numbers that we call tent-tiles. They are compact subsets of the one-, two-, or three-dimensional Euclidean space, depending on the particular special Pisot number.
