Hurst Coefficient in long time series of population size: Model for two plant populations with different reproductive strategies [PDF]

open access: yes, 2010
Can the fractal dimension of fluctuations in population size be used to estimate extinction risk? The problem with estimating this fractal dimension is that the lengths of the time series are usually too short for conclusive results.

Serotonergic System‐Targeted Nucleic Acid Hydrogel Coordinates Excitability Restoration and Circuit Reconstruction for Spinal Cord Injury Therapy

open access: yesAdvanced Materials, EarlyView.
The study reports a DNA/RNA heteroduplex hydrogel (SeroPTEN‐CG) that undergoes DNase‐mediated hydrogel‐to‐nanogel transition for spinal cord injury therapy by targeting the serotonergic system, combining 5‐hydroxytryptamine (5‐HT)‐mediated excitability restoration to reactivate dormant interneurons with phosphatase and tensin homolog (PTEN)‐targeted ...

Effect of mechanical scarification, chilling, and gibberellic acid on germination of Leucaena leucocephala seeds

open access: yesمجلة مركز بحوث التقنيات الاحيائية, 2013
Leucaena leucocephala is a tree species used for several agricultural purposes in Mediterranean region. The seeds of these species exhibit dormancy causing delayed germination.

NARFL Knockout Triggers Ferroptosis‐Driven Vascular Endothelial Dysfunction

open access: yesAdvanced Science, EarlyView.
NARFL is vital for CIA and oxidative stress resistance. NARFL deletion in HPMEC cells, zebrafish, and mice is lethal and rescued by a Ferroptosis inhibitor. NARFL deficiency disrupted its interaction with CIA proteins, decreased aconitase activity, increased IRP1 activity, induced Fe overload, and led to ferroptosis and oxidative stress, resulting in ...

Circular RNA PTPN4 Contributes to Blood‐Brain Barrier Disruption during Early Epileptogenesis

open access: yesAdvanced Science, EarlyView.
Epileptic condition induces CircPTPN4 upregulation, which promotes ECE‐1 expression through competitive sequestration of miR‐145a‐5p. The elevated ECE‐1 catalyzes the ET‐1 production, leading to p38/MAPK pathway activation and subsequent downregulation of tight junction protein expression. This cascade results in increased BBB permeability and enhanced

Seed factors involved in early seedling establishment of Festuca arundinacea (tall fescue) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Plant Biology and Biotechnology at Massey University, New Zealand [PDF]

open access: yes, 1995
New Zealand pastures are commonly based on vigorously growing Lolium (ryegrass) species. In many situations, however, it is often advantageous to combine the vigorous qualities of Lolium species with the versatility of other species such as Festuca ...

Cryopreserved Human Otic Neuronal Spheroids Self‐assemble for Functional Connectivity Analysis and Long‐term Ototoxicity Evaluation

open access: yesAdvanced Science, EarlyView.
This study establishes a robust and reproducible protocol for generating human otic neuronal spheroids (hONS) from cryopreserved hPSC‐derived pre‐placodal ectoderm cells. These hONS further differentiate into functional SGN‐like neurons, which extend neurite projections toward both murine hair cells and human cortical organoids, thereby forming ...
