Three blinded, placebo-controlled, block design, parallel-group confirmatory experiments were conducted, using an F4-ETEC PWD challenge model, each with a different vaccination-challenge interval (3, 7, and 21 days).
A vaccine dose below 108 CFU or a 105 CFU challenge resulted in poor or no protection, and a vaccination-challenge interval of 8 weeks did not improve the evaluation.
We studied the vaccine dose (from 106 to 108 CFU), two strains of mice (BALB/c and CD-1), the vaccination-challenge interval (4 and 8 weeks), and the challenge dose (104 and 105 CFU) and strain (16M and H38).
A randomized, masked, placebo-controlled, block design, parallel-group confirmatory study with two different vaccination-challenge intervals (7 and 21 days) was conducted for each challenge model.
The court is to consider three separate lawsuits by judges against the state challenging the long interval without a pay raise.
To quote from the latter paper originating from Chicago: "One fears that women who have difficulty negotiating the Medicaid consent process (for a peripartum TO {authors}) may be further challenged in obtaining interval sterilization.
We addressed these questions in a tri-peak procedure by challenging rats with unexpected retention-intervals (gaps).
HIIT (high intensity interval training) involves short, challenging bursts of activity with rests in between.
The saline- or METH-pretreated animals received either saline or METH (5 mg/kg×8 at 1 h intervals) challenges 72 hours after the preconditioning period.
The interval between sunitinib treatments appeared to have an impact on response to re-challenge; patients with an interval of > 6 months between sunitinib treatments had a median PFS of 16.5 months (compared with 6.0 months in those who were re-challenged within 6 months).
