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.
At the time of Henneman’s initial study of motor neuron recruitment, [1] it was known that neurons varied greatly in size, that is in the diameter and extent of the dendritic arbor, size of the soma, and diameter of axon. However, the functional significance of neuron size was not yet known.
If a correlation were to be drawn between Henneman's size principle [14] and the motor unit categorization of Burke regarding the order of motor unit recruitment, it would resemble the following order: the smallest units, S (slow) (Slow-Oxidative), would be recruited first, followed by larger FR (fast, resistant) (Fast-Oxidative) units, and ...
A clinical research associate (CRA), also called a clinical monitor or trial monitor, is a health-care professional who performs many activities related to medical research, particularly clinical trials. Clinical research associates work in various settings, such as pharmaceutical companies, medical research institutes and government agencies.
Mesenchymal stem cells (MSCs), also known as mesenchymal stromal cells or medicinal signaling cells, are multipotent stromal cells that can differentiate into a variety of cell types, including osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells which give rise to marrow adipose tissue).
In population dynamics and community ecology, recruitment is the process by which individuals are added to a population. [1] Successful recruitment is contingent on an individual surviving and integrating within the population; in some studies, individuals are only considered to have been recruited into a population once they've reached a certain size or life stage.
Snowball sampling is a recruitment method that employs research into participants' social networks to access specific populations. According to research mentioned in the paper written by Kath Browne, [20] using social networks to research is accessible. In this research, Kath Browne used social networks to research non-heterosexual women.
Monocytes will then develop into macrophages or dendritic cells upon tissue damage and recruitment of monocytes into the infected area. [1] During recruitment monocytes are distinct from macrophages and dendritic cells, but upon entering the infected area, monocytes will acquire inflammatory effector functions and then differentiate into ...
