We also determined that systemic administration of the SOD-mimetic, C3, for three weeks was sufficient to reduce ongoing superoxide production in aged wild-type animals (Fig. 2a and b).
This suggests that the initial dose of TGFβ-3 for 24 hours followed by 3D culture/hypoxia for three weeks was sufficient to differentiate MSCs toward a chondrogenic phenotype.
That doesn't seem like a very long time — only 42 meals, not 1,000 — but Havel and Stanhope have been studying fructose since the mid-1990s, and they seem confident that two weeks is sufficient to see if these sugars cause at least some of the symptoms of metabolic syndrome.
And would eight weeks be sufficient to help them achieve "optimum emotional well-being?" I don't know the answers to these questions.
In a study that was published in 2013 on compassion meditation, we found that 30 minutes a day of practice over the course of two weeks was sufficient to produce a change in behavior and in brain function.
It is unlikely that two weeks is sufficient time for inward migration of cells from the anastomoses to populate the stent NI.
This guideline states that a maximum treatment duration of six weeks is sufficient [ 33].
Previous research has also indicated that two weeks is sufficient to predict vessel remodeling and demonstrate whether or not intimal hyperplasia will occur.
We demonstrate for the first time that once-weekly intratumoral injection of AM9D in the absence of any carrier molecule, for four weeks, was sufficient to significantly reduce the rate of tumor growth and final tumor load in a dose-dependent and statistically significant manner (P ≤0.05).
Whereas elite athletes could have treatment duration of up to twelve weeks, six weeks are considered sufficient for amateur athletes, according to the KNGF guidelines [ 18].
Twelve weeks are known to be sufficient to judge the short-term effectiveness of a psoriasis treatment, but we specifically wanted to look at longer-term outcomes at 24 weeks which may better represent sustainable treatment adherence [ 17].
