PURPOSE Human Wharton's jelly stem cells (HWJSCs) are able to differentiate into skin and oral mucosa epithelial-like cells. In this work, we demonstrate for the first time the capability of HWJSCs to differentiate in vitro into cornea epithelial-like cells in a three-dimensional model. METHODS First, primary cell cultures of HWJSCs, corneal epithelial cells, and corneal keratocytes were cult...

In infants, eye constriction-the Duchenne marker-and mouth opening appear to index the intensity of both positive and negative facial expressions. We combined eye constriction and mouth opening that co-occurred with smiles and cry-faces (respectively, the prototypic expressions of infant joy and distress) to measure emotional expression intensity. Expression intensity and heart rate were measur...

The endoplasmic reticulum-derived type-I protein body (PB-I) from rice endosperm cells is an ideal candidate formulation for the oral delivery of bioencapsulated peptides as tolerogens for allergen-specific immunotherapy. In the present study, PBs containing the deconstructed Japanese cedar pollen allergens Cryptomeria japonica 1 (Cry j 1) and Cry j 2 were concentrated by treatment with thermos...

BACKGROUND Bowlby and Ainsworth hypothesized that maternal responsiveness is displayed in the context of infant distress. Depressed mothers are less responsive to infant distress vocalizations (cry) than non-depressed mothers. The present study focuses on acoustical components of infant cry that give rise to responsive caregiving in clinically depressed (n = 30) compared with non-depressed moth...

The acoustic analysis of infant cry is used to deduce information on the state of health of new-born babies as well as of children a few weeks old. Crying is the first tool of communication for an infant. These cries seem to be uniform, but there are a lot of differences between two infant‟s cries. Infant cry characteristics reflect the development and possibly the integrity of the central nerv...

The current consensus model for the circadian clock in mammals is based on a transcription-translation feedback loop. In this model, CRY and PER proteins repress their own transcription by suppressing the transactivator function of the CLOCK:BMAL1 heterodimer directly (physical model) and by facilitating post-translational modifications (chemical model). Most of the data for this model come fro...

BACKGROUND Interleukin-31 (IL-31) is a recently identified cytokine produced by Th2 cells that is involved in the development of atopic dermatitis-induced skin inflammation and pruritus. Its receptor, IL-31RA, is expressed by a number of cell types, including epithelial cells, eosinophils, and activated monocytes and macrophages. To date, however, the regulation of Th2 responses by distinct cel...

The circadian clock is a core molecular mechanism that allows organisms to anticipate daily environmental changes and adapt the timing of behaviors to maximize efficiency. In social insects, the ability to maintain the appropriate temporal order is thought to improve colony efficiency and fitness. We used the newly sequenced fire ant (Solenopsis invicta) genome to characterize the first ant cir...

Cryptochromes (CRY) are blue-light photoreceptors that mediate various light responses in plants and animals. It has long been demonstrated that Arabidopsis CRY (CRY1 and CRY2) C termini (CCT1 and CCT2) mediate light signaling through direct interaction with COP1. Most recently, CRY1 N terminus (CNT1) has been found to be involved in CRY1 signaling independent of CCT1, and implicated in the inh...

Insulin-like growth factor (IGF) signaling plays an important role in cell growth and proliferation and is implicated in regulation of cancer, metabolism, and aging. Here we report that IGF-1 level in blood and IGF-1 signaling demonstrates circadian rhythms. Circadian control occurs through cryptochromes (CRYs)-transcriptional repressors and components of the circadian clock. IGF-1 rhythms are ...
