Example: "The organization requires a regulated number of participants for the study to ensure valid results."
Alternatives: "a controlled number of" or "a limited number of".
In Finland, only a small and regulated number of RECs dealt with clinical research (21 (5 since 2010) and a central committee) (Table 3).
As a result, they possess the unique properties: nanosize range, monodispersity, and rigid and stable globular structure with a large and well-regulated number of functional groups and surface charges.
In addition to pathways highlighted by KEGG analysis, fasting down-regulated a number of genes (e.g., TGFβ, BMP) that mediate mesenchymal stem cell (MSC) commitment, an early step in the formation of new adipocytes (Additional file 1).
The majority of genes expressed in neurons were down-regulated; a number of these were involved in regulatory pathways including synapse function, calcium signalling, long-term potentiation and ERK/MAPK signalling.
Reciprocally, also satellite cells transcribe in a regulated manner a number of genes coding for ECM proteins, such as versican, glypicans and fibrillin-2, based on the necessity to bind growth factors [198].
The expression of MMPs is usually tightly regulated, and a number of studies provide evidence of carefully controlled MMP involvement in developmentally regulated processes such as ovulation, embryogenic growth and differentiation, and organ development [ 6- 8].
Furthermore, PS treatment released FD cells from cell cycle arrest and up-regulated a significant number of genes involved in cell cycle regulation.
Overall, macrophages exhibited more robust signals than whole lung, with both up-regulated and a small number of down-regulated genes identified.
a number of genes up-regulated; b number of genes down-regulated Although plant growth measured by shoot biomass was reduced by 20% under mild N stress, the baseline expression levels of most genes in the genome remained similar.
Another growth-related gene associated with muscle atrophy, P311, is a novel gene reported to be down-regulated in a number of muscle atrophic conditions [ 17] but up-regulated under moderate dietary restriction [ 18].
