Regenerative medicine is a translational field which combines tissue engineering and molecular biology to construct spare organs or help injured or defective tissues to regenerate or restore their normal functions. This is particularly important with specific organs such as heart, central nervous system, retina or limbs which possess very limited regenerative capacity. As such, regenerative medicine has received peculiar attention in the last decade. In this regard, Wnt/β-catenin signaling pathway has been subject to intensive research, since it plays many essential roles in the regulation of the progenitor cell fate, developmental decisions, proliferation during embryonic development, and adult tissue homeostasis...

The dynamics of metabolites from leaves to roots of Panax ginseng during development has revealed the tissue-specific and year-specific metabolic networks. Being an essential Oriental medicinal plant, ginseng (Panax ginseng Meyer) is a slow-growing perennial herb-accumulating pharmaceutically active metabolites such as ginsenosides in roots during growth. However, little is known about how ginseng plants survive in the harsh environments such as winter cold and summer heat for a longer period and accumulates those active metabolites as the plant grows...

The assessment of emotional factors, in addition to other psychosocial factors, has been recommended as a means of identifying individuals with chronic pain who may not respond to certain pain treatments. Systematic reviews of the evidence regarding the prediction of responsiveness to a treatment called the spinal cord stimulator (SCS) have yielded inconclusive results. Emotional intelligence is a term which refers to the ability to identify and manage emotions in oneself and others and has been shown to be inversely associated with emotional distress and acute pain...

The fields of medicine and oncology made substantial progress between 1800 and 1885. The first half of this period was dominated by the spectacular progress in physiology, cytology, histology, histopathology, and diagnostic microscopy. In the second half of the period, advancements in surgical techniques, anesthesia, asepsis, and laboratory medicine, including bacteriology, chemistry, and biochemistry, led to the development of medical specialties, including surgical pathology and surgical oncology. Although wars, revolutions, and socioeconomic upheavals interrupted the daily life of the populace, distinguished artists, scientists, and physicians continued, against all odds, to advance their field of interest...

Chris Fields, Michael Levin
A fundamental aspect of life is the modification of anatomy, physiology, and behavior in the face of changing conditions. This is especially illustrated by the adaptive regulation of growth and form that underlies the ability of most organisms-from single cells to complex large metazoa-to develop, remodel, and regenerate to specific anatomical patterns. What is the relationship of the genome and other cellular components to the robust computations that underlie this remarkable pattern homeostasis? Here we examine the role of constraints defined at the cellular level, especially endogenous bioelectricity, in generating and propagating biological information...

REVIEW
Shuguang Zhang
Peptides are ubiquitous in nature and useful in many fields, from agriculture as pesticides, in medicine as antibacterial and antifungal drugs founded in the innate immune systems, to medicinal chemistry as hormones. However, the concept of peptides as materials was not recognized until 1990 when a self-assembling peptide as a repeating segment in a yeast protein was serendipitously discovered. Peptide materials are so called because they have bona fide materials property and are made from simple amino acids with well-ordered nanostructures under physiological conditions...

The aim of the current report is to provide guidance relevant to psychological evaluation for healthcare providers and researchers working in the field of disorders of sexual development (DSD). In doing so, we give careful consideration to methodological issues and limitations that may influence the utility of investigations. For example, rarity and heterogeneity of DSD conditions restrict sample sizes when conducting evaluations aimed at establishing condition-specific psychological outcomes. At the same time, the potential for stigmatization by virtue of conducting psychological evaluations is particularly high given the fundamental contribution of sex and gender to one's sense of self and integrity...

Point-of-care ultrasound (POC-US) is increasingly used especially in emergency and critical-care medicine. It is focused, quick and does not expose patients to ionizing radiation. It encompasses all organ systems and has well-defined indications. Lung ultrasound (LUS) represents one of the most exciting applications in the field of POC-US. It is particularly important to emphasize the role of LUS in neonatology due to the specific pathology inherent in lung immaturity as well as in the particular sensitivity of neonates to repeated radiation exposure...

This Review highlights how we can build upon the relatively new and rapidly developing field of research into bacterial quorum sensing (QS). We now have a depth of knowledge about how bacteria use QS signals to communicate with each other and to coordinate their activities. In recent years there have been extraordinary advances in our understanding of the genetics, genomics, biochemistry, and signal diversity of QS. We are beginning to understand the connections between QS and bacterial sociality. This foundation places us at the beginning of a new era in which researchers will be able to work towards new medicines to treat devastating infectious diseases, and use bacteria to understand the biology of sociality...

Pluripotent stem cells have great potential for developmental biology and regenerative medicine. Embryonic stem cells, which are obtained from blastocysts, and induced pluripotent stem cells, which are generated by the reprogramming of somatic cells, are two main types of pluripotent cells. It is important to understand the regulatory network that controls the pluripotency state and reprogramming process. Various types of noncoding RNAs (ncRNAs) have emerged as substantial components of regulatory networks...
