Patient recruitment in the US includes a variety of services—typically performed by a Patient Recruitment Service Provider—to increase enrollment into clinical trials. Presently, the patient recruitment industry is claimed to total $19 billion [1] per year. [2] Patient enrollment is the most time-consuming aspect of the clinical trial process.
Motor unit recruitment is a measure of how many motor neurons are activated in a particular muscle, and therefore is a measure of how many muscle fibers of that muscle are activated. The higher the recruitment the stronger the muscle contraction will be.
When discussing population dynamics, behavioral ecology, and cell biology, recruitment refers to several different biological processes. In population dynamics, recruitment is the process by which new individuals are added to a population, whether by birth and maturation or by immigration. [ 1 ]
The discipline of anatomy can be subdivided into a number of branches, including gross or macroscopic anatomy and microscopic anatomy. [10] Gross anatomy is the study of structures large enough to be seen with the naked eye, and also includes superficial anatomy or surface anatomy, the study by sight of the external body features.
TLRs are a major class of pattern recognition receptor, that exists in all coelomates (animals with a body-cavity), including humans. [35] The complement system exists in most life forms. Some invertebrates, including various insects, crabs , and worms utilize a modified form of the complement response known as the prophenoloxidase (proPO) system.
[1] [2] The counterpart to gross anatomy is the field of histology, which studies microscopic anatomy. [ 1 ] [ 2 ] Gross anatomy of the human body or other animals seeks to understand the relationship between components of an organism in order to gain a greater appreciation of the roles of those components and their relationships in maintaining ...
Research on thyroid cancer has elucidated the theory that paracrine signaling may aid in creating tumor microenvironments. Chemokine transcription is upregulated when Ras is in the GTP-bound state. The chemokines are then released from the cell, free to bind to another nearby cell.
In 1903, Nikolai K. Koltsov proposed that the shape of cells was determined by a network of tubules that he termed the cytoskeleton. The concept of a protein mosaic that dynamically coordinated cytoplasmic biochemistry was proposed by Rudolph Peters in 1929 [12] while the term (cytosquelette, in French) was first introduced by French embryologist Paul Wintrebert in 1931.
