Advanced Science, EarlyView.The pathogenic role of PHEX isn't fully determined, and there is no radical cure for X‐linked hypophosphatemic rickets (XLHR). This study makes the first attempt to perform gene therapy using a minicircle DNA (MC‐DNA) vector expressing a fragment of FGF23 (amino acids 180‐251) in Phex‐T1349C mice and suggests MC‐DNA as a promisingly safe and effective ...

Advanced Science, EarlyView.The paper proposes that the root cause of aging is the loss of anatomical goal‐directedness after development. Using evolutionary neural cellular automata simulations, the authors show that after the organism has reached its developmental homeostatic setpoint (the adult morphology), the absence of target state to pursue leads to a drifting anatomical ...

Advanced Science, EarlyView.At 2 5 °C, thermal activation initiates: i) CcIav/CcNan heterotetramer assembly → Ca2⁺ influx; ii) CcPKCα phosphorylation → AKH signaling potentiation; iii) CcAKH1 binding to membrane‐localized CcAKHR → energy mobilization (lipid catabolism/glycogenolysis) and vitellogenin transport via follicular patency; iv) Oocyte maturation → summer‐form nymph ...

The Economic Foundations of Demographic Transition [PDF]
The paper develops a general equilibrium model where population sources, such as fertility and mortality rates, are chosen variables. It is shown that the evolution of population over time depends on income and relative prices of mortality and fertility ...
