Sonoepigenetic Modification Mechanoprimes Early Osteogenic Commitment in Mesenchymal Stem Cells

open access: yesAdvanced Science, EarlyView.
Brief 10 min bursts of high frequency (10 MHz) vibrational mechanostimulation to stem cells are shown to activate their epigenetic machinery to condition their differentiation down an osteogenic lineage within just 3 days, which is much earlier than that with other forms of mechanostimuli, and without requiring any biochemical additives.

Dynamical strategies for obstacle avoidance during Dictyostelium discoideum aggregation: a Multi-agent system model [PDF]

open access: yes, 2019
Chemotaxis, the movement of an organism in response to chemical stimuli, is a typical feature of many microbiological systems. In particular, the social amoeba \textit{Disctyostelium discoideum} is widely used as a model organism, but it is not still ...

Tensin links energy metabolism to extracellular matrix assembly. [PDF]

open access: yes, 2017
The regulation of integrin function is key to fundamental cellular processes, including cell migration and extracellular matrix (ECM) assembly. In this issue, Georgiadou et al. (2017. J. Cell Biol.

Inhaling Eugenol Inhibits NAFLD by Activating the Hepatic Ectopic Olfactory Receptor Olfr544 and Modulating the Gut Microbiota

open access: yesAdvanced Science, EarlyView.
Inhalable eugenol (EUG) from clove oil attenuates NAFLD by activating hepatic olfactory receptor Olfr544, triggering cAMP/PKA/CREB signaling to enhance lipolysis/oxidation. EUG concurrently restores gut microbiota, enriching probiotics (L. reuteri XR23/L. johnsonii XR25) and metabolites (IPA/5‐HIAA) that suppress lipogenesis.

Virulence‐Selective Trap–Capture–Kill Antibacterial Nanostructures With Immune–Metabolic Regulation for Treating Implant‐Associated Infections

open access: yesAdvanced Science, EarlyView.
A virulence‐selective antibacterial system based on fascaplysin derivative 14‐modified TiO2 nanostructure (F‐14‐TNA) is developed for treating implant‐associated infections. F‐14‐TNA selectively traps hyperpathogenic bacteria via chemotaxis, captures them electrostatically, and kills them via reactive oxygen species‐mediated pathways.

The effects of portacaval shunt upon hepatic cholesterol synthesis and cyclic AMP in dogs and baboons [PDF]

open access: yes, 1980
Hepatic cholesterol synthesis, hepatic cyclic AMP, and portal and peripheral insulin and glucagon levels were investigated in nine dogs and three baboons after complete portacaval shunt.

CBS domains form energy-sensing modules whose binding of adenosine ligands is disrupted by disease mutations [PDF]

open access: yes, 2004
CBS domains are defined as sequence motifs that occur in several different proteins in all kingdoms of life. Although thought to be regulatory, their exact functions have been unknown.

Transcriptomics Guided Engineering of Exosome‐Encapsulated Bifunctional Nanosheets Targeting the Immune‐PI3K/Akt Axis for Osteoporosis Therapy

open access: yesAdvanced Science, EarlyView.
A multifunctional nanosheet–exosome hybrid system incorporating f‐CA(OH) nanosheets enriched with abundant surface vacancies are developed. These nanosheets fuse with natural exosomes, endowing them with nanozyme‐like catalytic capabilities while retaining their inherent biological functions.

The role of cyclic nucleotide on fetal and neonantal erythropoiesis [PDF]

open access: yes, 1974
For the purpose to reveal the changes in stimulatory effect of dibutyryl-cyclic- AMP on erythropoiesis during ontogenetic development, the author studied syntheses of DNA, RNA and protein of erythroid cells in fetal liver, neonatal and adult bone marrows
