BioSD
The BioSample Database (BioSD) is a database at European Bioinformatics Institute for the information about the biological samples used in sequencing. It stores submitter-supplied metadata about the biological materials from which data stored in the National Center for Biotechnology Information’s (NCBI) primary data archives are derived. NCBI’s archives hosts data pertaining to diverse types of samples from many species, and as such the BioSample database is similarly diverse. Examples of a BioSample include a primary tissue biopsy, an individual organism or an environmental isolate. The BioSample database captures sample metadata in a structured way by encouraging use of controlled sample attribute field name vocabularies. This metadata is key in giving the sample data context, allowing it to be more fully understood, reused, and enables aggregation of disparate data sets. Sample metadata is linked to relevant experimental data across many archival databases relieving submitter burden by enabling one-time submission of sample description. They then can reference that sample, when necessary, when making data deposits to other archives. BioSample records are indexed and searchable, supporting cross-database queries by sample description.

Glycyrrhetinic Acid in Liver Cancer Therapy
Liver cancer is one of the most common causes of cancer mortality worldwide. Chemotherapy and radiotherapy are the conventional therapies generally employed in patients with liver tumors. The major issue associated with the administration of chemotherapeutics is their high toxicity and lack of selectivity, leading to systemic toxicity that can be detrimental to the patient’s quality of life. An important approach to the development of original liver-targeted therapeutic products takes advantage of the employment of biologically active ligands able to bind specific receptors on the cytoplasmatic membranes of liver cells. In this perspective, glycyrrhetinic acid (GA), a pentacyclic triterpenoid present in roots and rhizomes of licorice, has been used as a ligand for targeting the liver due to the expression of GA receptors on the sinusoidal surface of mammalian hepatocytes, so it may be employed to modify drug delivery systems (DDSs) and obtain better liver or hepatocyte drug uptake and efficacy.

Nature’s Role in Outdoor Therapies
Outdoor therapies are intentional therapeutic processes that are (1) place-based, (2) feature active bodily engagement, and (3) recognize nature-human kinship. Significant variety exists in practice, from walk and talk therapy, to expedition-based wilderness therapy, to garden and animal-assisted therapies. These approaches have shown improvement across a wide range of social, emotional, physical, physiological, and psychological outcomes and populations.

Harvestman Anatomy
Harvestmen (Opiliones) are an order of arachnids and share many common characteristics with other arachnids. However, several differences separate harvestmen from other arachnid orders such as spiders. The bodies of opliones are divided into two tagmata (arthropod body regions): the abdomen (opisthosoma) and the cephalothorax (prosoma). Unlike spiders, the juncture between the abdomen and cephalothorax is often poorly defined. Harvestmen have chelicerae, pedipalps and four pairs of legs. Most harvestmen have two eyes, although there are eyeless species.

Redundancy Principle
The redundancy principle in biology expresses the need of many copies of the same entity (cells, molecules, ions) to fulfill a biological function. Examples are numerous: disproportionate numbers of spermatozoa during fertilization compared to one egg, large number of neurotransmitters released during neuronal communication compared to the number of receptors, large numbers of released calcium ions during transient in cells and many more in molecular and cellular transduction or gene activation and cell signaling. This redundancy is particularly relevant when the sites of activation is physically separated from the initial position of the molecular messengers. The redundancy is often generated for the purpose of resolving the time constraint of fast-activating pathways. It can be expressed in terms of the theory of extreme statistics to determine its laws and quantify how shortest paths are selected. The main goal is to estimate these large numbers from physical principles and mathematical derivations. When large distance separate the source and the target (a small activation site), the redundancy principle explains that this geometrical gap can be compensated by large number. Had nature used less copies than normal, activation would have taken a much longer time, as finding a small target by chance is a rare events and falls into narrow escape problems.
