Inner-ear abnormalities and their functional consequences in Belgian Waterslager canaries (Serinus canarius) [PDF]

open access: yes, 1994
Recent reports of elevated auditory thresholds in canaries of the Belgian Waterslager strain have shown that this strain has an inherited auditory deficit in which absolute auditory thresholds at high frequencies (i.e. above 2.0 kHz) are as much as 40 dB

A Novel Antigen Sensitive to Calcium Chelation That is Associated with the Tip Links and Kinocilial Links of Sensory Hair Bundles [PDF]

open access: yes, 2003
Tip links are extracellular, cell-surface-associated filaments of unknown molecular composition that are thought to gate the mechanotransducer channel of the sensory hair cell.

Analysis of gene expression profiles between apical papilla tissues, stem cells from apical papilla and cell sheet to identify the key modulators inMSCs niche [PDF]

open access: yesCell Proliferation, 2017
AbstractObjectivesThe microenvironmental niche plays the key role for maintaining the cell functions. The stem cells from apical papilla (SCAPs) are important for tooth development and regeneration. However, there is limited knowledge about the key factors in niche for maintaining the function ofSCAPs.

Effect of bFGF on the growth and matrix turnover of stem cells from human apical papilla: Role of MEK/ERK signaling

open access: yesJournal of the Formosan Medical Association, 2020
Background/Purpose: Basic fibroblast growth factor (bFGF) exhibits multiple biological functions in various tissues. Stem cells from apical papilla (SCAP) can be isolated from human apical papilla tissues in developmental teeth of children.

Amelogenin as a regenerative endodontic molecule for immature teeth with apical periodontitis. An experimental study

open access: yesJournal of Oral Biology and Craniofacial Research, 2022
Vitality of the dentin-pulp complex depends on cell activity and signalling processes. Amelogenin protein regulates cell signalling pathways during tooth development by activating the Wnt/β-catenin intercellular signalling pathway.

Expression and Misexpression of the miR-183 Family in the Developing Hearing Organ of the Chicken. [PDF]

open access: yesPLoS ONE, 2015
The miR-183 family consists of 3 related microRNAs (miR-183, miR-96, miR-182) that are required to complete maturation of primary sensory cells in the mammalian inner ear.

Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction

open access: yesAdvanced Science, EarlyView.
During floral induction, various environmental and endogenous signals converge to regulate the florigen protein, which is transported from leaves to the SAM to initiate flowering. Within the SAM, a complex network of receptor kinases and small peptides orchestrates floral development with high spatiotemporal precision.
