Saliva is a non-invasive biofluid, which is easy to collect, transport, and store. Because of its accessibility and connection to systemic diseases, saliva is one of the best candidates for the advancement of point-of-care medicine, where individuals are able to easily monitor their health status by using portable convenient tools such as smartphones. There are a variety of scenarios with which saliva can be used: studies have been conducted on using saliva to measure stress hormones, enzyme levels, developmental disease biomarkers, and even cancer mutations...

The Ser and Thr kinase AKT, also known as protein kinase B (PKB), was discovered 25 years ago and has been the focus of tens of thousands of studies in diverse fields of biology and medicine. There have been many advances in our knowledge of the upstream regulatory inputs into AKT, key multifunctional downstream signaling nodes (GSK3, FoxO, mTORC1), which greatly expand the functional repertoire of AKT, and the complex circuitry of this dynamically branching and looping signaling network that is ubiquitous to nearly every cell in our body...

Tanshinone IIA (Tan-IIA) is derived from the dried roots of Salvia miltiorrhiza Bunge, a traditional Chinese medicine. Although Salvia miltiorrhiza has been applied for many years, the toxicity of the mono-constituent of Salvia miltiorrhiza, tanshinone IIA, is still understudied. This study evaluated the cardiotoxicity and developmental malformations of Tan-IIA by using zebrafish normal embryos and dechorionated embryos. After treatment with Tan-IIA in different concentrations for four-day periods, obvious pericardial edema, spinal curvature, and even missing tails were observed in zebrafish embryos...

Toxicological testing associated with developmental toxicity endpoints are very expensive, time consuming and labor intensive. Thus, developing alternative approaches for developmental toxicity testing is an important and urgent task in the drug development filed. In this investigation, the naïve Bayes classifier was applied to develop a novel prediction model for developmental toxicity. The established prediction model was evaluated by the internal 5-fold cross validation and external test set. The overall prediction results for the internal 5-fold cross validation of the training set and external test set were 96...

The current classification of cells in an organism is largely based on their anatomic and developmental origin. Cells types and tissues are traditionally classified into those that arise from the three embryonic germ layers, the ectoderm, mesoderm and endoderm, but this model does not take into account the organization of cell type-specific patterns of gene expression. Here, we present computational models for cell type and tissue specification derived from a collection of 921 RNA-sequencing samples from 272 distinct mouse cell types or tissues...

Since the rise of evo-devo (evolutionary developmental biology) in the 1980s, few authors have attempted to combine the increasing knowledge obtained from the study of model organisms and human medicine with data from comparative anatomy and evolutionary biology in order to investigate the links between development, pathology, and macroevolution. Fortunately, this situation is slowly changing, with a renewed interest in evolutionary developmental pathology (evo-devo-path) in the past decades, as evidenced by the idea to publish this special, and very timely, issue on "Developmental Evolution in Biomedical Research...

An important mandate when imaging pediatric patients is the reduction of radiation exposure to the lowest possible level consistent with good quality diagnostic imaging, so individual selection of radiopharmaceutical dosage and imaging technique is essential. Although the logistics of image acquisition and the approach to interpretation mirror the more common use in adults, the challenges of imaging young children typically require greater attention to patient preparation, positioning, and supervision during imaging, with the use of parental or family engagement in the procedure, gentle restraint, and occasionally the need for sedation...

BACKGROUND: Knowledge of molecular marker (typically protein or mRNA) expression in neural systems can provide insight to the chemical blueprint of signal processing and transmission, assist in tracking developmental or pathological progressions, and yield key information regarding potential medicinal targets. These markers are particularly relevant in the mammalian brain in light of its unsurpassed cellular diversity. Accordingly, molecular expression profiling is rapidly becoming a major approach to classify neuron types...

: Background: The Institute of Medicine (IOM) and the Quality and Safety Education for Nurses (QSEN) project have identified six nursing competencies and supported their integration into undergraduate and graduate nursing curricula nationwide. But integration of those competencies into clinical practice has been limited, and evidence for the progression of competency proficiency within clinical advancement programs is scant. Using an evidence-based approach and building on the competencies identified by the IOM and QSEN, a team of experts at an academic health system developed eight competency domains and 186 related knowledge, skills, and attitudes (KSAs) for professional nursing practice...

Year after year, conditions, quality, and duration of human lives have been improving due to the progress of science, technology, education, and medicine, which however has a downside. Owing to improvement in children's nutrition, developmental acceleration occurs that imbalances a child's system. Because of virtual worlds of the Internet, social experience of teenagers expands and clashes with puberty of adolescents. Due to the comfort of cities, urbanization emerges and causes stress to adults because of artificial light, noise, pollution, violations of personal space, and family disruption...

Cultured stem cells have become a standard platform not only for regenerative medicine and developmental biology but also for biophysical studies. Yet, the characterization of cultured stem cells at the level of morphology and macroscopic patterns resulting from cell-to-cell interactions remain largely qualitative. Here we report the collective motion of cultured neural progenitor cells (NPCs), which are multipotent stem cells that give rise to cells in the central nervous system[1]. At low densities, NPCs moved in an amoeba-like fashion and with random motion...

As a novel population of neural crest-origin precursor cells, skin-derived precursor cells (SKPs) can be isolated from both embryonic and adult dermis. These cells have important values for research and potential clinical application in wound healing, organ regeneration and disease treatment for advantages in the abundance of cell sources, accessibility, potential of multipotent differentiation, and absence of ethical concerns. Here we review the developmental and anatomical origins of SKPs and their potential application in regenerative medicine...

Alternative pre-mRNA splicing is a tightly controlled process conducted by the spliceosome, with the assistance of several regulators, resulting in the expression of different transcript isoforms from the same gene and increasing both transcriptome and proteome complexity. The differences between alternative isoforms may be subtle but enough to change the function or localization of the translated proteins. A fine control of the isoform balance is, therefore, needed throughout developmental stages and adult tissues or physiological conditions and it does not come as a surprise that several diseases are caused by its deregulation...

Steroid hormones mediate critical lineage-specific developmental and physiologic responses. They function by binding their cognate receptors, which are transcription factors that drive specific gene expression programs. The requirement of most prostate cancers for androgen and most breast cancers for estrogen has led to the development of endocrine therapies that block the action of these hormones in these tumors. While initial endocrine interventions are successful, resistance to therapy often arises. We will review how steroid receptor-dependent genomic signaling is affected by genetic alterations in endocrine therapy resistance...

A three-dimensional (3D) tissue generated in vitro is a promising source to study developmental biology and regenerative medicine. In the last decade, Yoshiki Sasai's group have developed a 3D stem cell culture technique known as SFEBq and demonstrated that embryonic stem cells (ESCs) have an ability to self-organize stratified neural tissue including 3D-retina. Furthermore, we have reported that ESC-derived retinal tissue can form an optic cup and a ciliary margin, which are unique structures in the developing retina...
