Deep Learning Network‐Tailored Microenvironment Matching of 4D Bioprinting Bioactive Scaffolds for Bone Regeneration

open access: yesAdvanced Science, EarlyView.
A DLN dataset was built to analyze MABS composition versus in vitro/in vivo osteogenesis and angiogenesis. An MLP neural network, taking BG morphological parameters as input, extracts bioactive features from these datasets. A rabbit tibial defect model then validates 4D‐printed MABS for adaptability and bone regeneration in critical defects.

A Bright Ratiometric Dipyrene Probe for Functional Imaging of Condensate Microenvironments in Living Cells

open access: yesAdvanced Science, EarlyView.
Ratiometric dipyrene imaging resolves monomer (M) and excimer (E) channels and computes pixel‐wise E/M maps within biomolecular condensates, yielding physicochemical fingerprints shaped by coupled polarity‐related solvation and microviscosity. These spatial fingerprints enable quantitative phenotyping of cellular states, exemplified by separation of ...

RPLP2 Mediates the Beneficial Effects of Exercise on Stress Resistance Through Muscle–Brain Communication

open access: yesAdvanced Science, EarlyView.
A novel exercise‐inducible myokine acidic ribosomal protein P2 (RPLP2), initially identified from human trials, is presented here, whose circulating levels negatively correlate with clinical anxiety severity. Muscle‐derived RPLP2 enhances hippocampal ribosomal assembly and adult neurogenesis to rescue stress‐induced anxiety deficits.

Characterization of juvenile wood to mature wood transition age in black spruce (Picea mariana (Mill.) B.S.P.) at different stand densities and sampling heights

open access: yes, 2005
The radial pattern of both maximum ring density and ring area of 36 black spruce trees were used to determine the transition age from juvenile wood to mature wood.

Self‐Assembly of Antigenic Peptide Nanofibrils Templates the Growth of Silica Nanoparticles for Nanovaccines

open access: yesAdvanced Science, EarlyView.
Antigenic peptides Aβ42 and E7 self‐assemble into nanofibrils; APTES and TEOS induce SiO2 NP formation on these fibrils to form SiO2@fibril nanovaccines, which activate BMDCs in vitro. In vivo, SiO2@Aβ42 fibril nanovaccines alleviate AD symptoms and clear Aβ42 plaques in APP/PS1 mice, and SiO2@E7 fibril nanovaccines inhibit tumor growth and promote ...

Estimating the Age of Demarcation of Juvenile and Mature Wood in Douglas-Fir [PDF]

open access: yes, 2007
In order to characterize trends and to estimate the age of transition from juvenile to mature wood in Douglas-fir, piecewise linear regression analysis was applied to the radial pattern of intra-ring characteristics found in increment cores of Douglas ...

High‐Density E. Coli Cultivation Arrays for Combinatorial Drug Testing With Subsequent Lipid Profiling by MALDI‐MS

open access: yesAdvanced Science, EarlyView.
High‐throughput antibiotic cross‐gradient assays on microdroplet arrays. A multichannel printhead together with five pressure regulators forms droplet arrays of up to 20 832 droplets within 25 minutes. Each droplet contains unique concentrations of antibiotics, allowing to moniture a vast spectrum of bacterial repsonses over night. The bacterial growth

Wood-inhabiting fungi on pedunculate oak coarse woody debris in relation to substratum quantity and forest age

open access: yesActa Mycologica, 2013
Wood-inhabiting fungi on pedunculate oak (Quercus robur) coarse woody debris (CWD) was investigated in 50 plots of 0.1 ha in oak stands of different ages in Lithuania.

Radiata pine pH and buffering capacity: Effect of age and location in the stem

open access: yesMaderas: Ciencia y Tecnología, 2014
In this work the effect of age and location within the stem on pH and buffering capacity of radiata pine sapwood was investigated. Mature and juvenile wood samples from three different heights in the trunk were obtained from 20, 25, and 30 year-old trees.

DEMARCATION OF JUVENILE AND MATURE WOOD OF Corymbia citriodora

open access: yes, 2015
This paper had the objective of determining the transition regions between the juvenile and mature wood of Corymbia citriodora (Eucalyptus citriodora) of 29 years of age from the Experimental Station of Forest Science (EECFA-LCF/ESALQ-USP), located in Anhembi, in the State of São Paulo. The regions of juvenile and mature wood were characterized through
