Despite extensive studies of the effects of herbal-derived small molecules in the biopharmaceutical and biomedical sciences, their low solubility and stability remain a challenge. Here we focus on baicalein, a small molecule showing potential against neurodegenerative diseases such as Parkinson's and Alzheimer's. However, therapeutic usage in vivo is challenged by low solubility and stability. To address this we have applied neutrally-charged nanoliposome (NLP) as carrier for baicalein. Baicalein was incorporated into NLP to form NLP-Ba at molar baicalain:lipid ratios of up to 1:3, giving a drug entrapment efficiency of 96...

Innovation and progress in radiation oncology depend on discovery and insights realized through research in radiation biology. Radiobiology research has led to fundamental scientific insights, from the discovery of stem/progenitor cells to the definition of signal transduction pathways activated by ionizing radiation that are now recognized as integral to the DNA damage response (DDR). Radiobiological discoveries are guiding clinical trials that test radiation therapy combined with inhibitors of the DDR kinases DNA-dependent protein kinase (DNA-PK), ataxia telangiectasia mutated (ATM), ataxia telangiectasia related (ATR), and immune or cell cycle checkpoint inhibitors...

Although mice have been the most frequently used experimental animals in many research fields due to well-established gene manipulation techniques, recent evidence has revealed that rodent models do not always recapitulate pathophysiology of human neurological and psychiatric diseases due to the differences between humans and rodents. The recent developments in gene manipulation of non-human primate have been attracting much attention in the biomedical research field, because non-human primates have more applicable brain structure and function than rodents...

The label "translational research" (TR) has become ever more popular in the biomedical domain in recent years. It is usually presented as an attempt to bridge a supposed gap between knowledge produced at the laboratory bench and its use at the clinical bedside. This is claimed to help society harvest the benefits of its investments in scientific research. The past decade has witnessed a remarkable acceleration in the pace of translational cancer medicine - genome sequencing of various human cancers has been broadly deployed in drug discovery programs, diagnostic tests have been developed to predict molecularly targeted anticancer agents, advent of cancer immunotherapies, an enhanced appreciation of the complex interactions that exist between tumor cells and their microenvironment have revolutionized the management of cancers...

Correctly designed bacteriophage therapeutics are the cornerstone for a successful outcome of bacteriophage therapy. Here we overview strategies on how to choose bacteriophages and their bacterial hosts at different steps of a bacteriophage cocktail development in order to comply with all quality and safety requirements based on the already existing essentially empirical experience in bacteriophage therapy and current accomplishments in modern biomedical sciences. A modification of the classic Appelmans' method (1922) to assess stability of bacteriophage activity in liquid media is presented in order to improve the overall performance of therapeutic bacteriophages individually and collectively in the cocktail...

Well over 90% of studies in biomedical sciences are performed on single animals. While knowledge of the genetics, development and physiology of single individuals accrues, an understanding of the biological mechanisms by which individuals interact has barely budged. Yet many of society's greatest problems derive from an inability of humans to get along with each other. Studies in social neuroscience are primarily observational and rarely employ subjects who physically interact. Thus, social interaction represents a largely unexplored frontier of biology...

Only once we agree upon our understanding of what words really mean can we debate whether a concept, represented by those words, is or not well represented significantly in specific application. Conceptual clarity and predicative/impredicative competence are the fundamental components for managing information more effectively in Health Informatics, Healthcare and Medicine applications, while promoting innovation and creativity. Medicine was always the art and science of healing. The science became more and more a mechanistic technology in Healthcare; the art was dropped altogether...

Identification of molecular ligands that recognize peptides or proteins is significant but poses a fundamental challenge in chemical biology and biomedical sciences. Development of cyclic peptidomimetic library is scarce, and thus discovery of cyclic peptidomimetic ligands for protein targets is rare. Herein we report the unprecedented one-bead-two-compound (OBTC) combinatorial library based on a novel class of the macrocyclic peptidomimetics γ-AApeptides. In the library, we utilized the coding peptide tags synthesized with Dde-protected α-amino acids, which were orthogonal to solid phase synthesis of γ-AApeptides...
