Endogenous avidin and biotin were blocked using the Vector Avidin/Biotin Blocking Kit (Vector Laboratories, Inc., Burlingame, CA), and further blocking was achieved using swine serum.
A stratified (on center and BMI), blocked randomization was achieved using a random number program in S-plus written by the study biostatistician (R F B). Numbered, sealed envelopes were opened by the Study Coordinator at the time of randomization.
Blocking of HIF-1α was achieved using the commercially available inhibitors CTM (Chetomin, NSC 289491, Invitrogen), and digoxin (Sigma-Aldrich, Buchs, Switzerland).
Blocking of the membrane was achieved using 5% nonfat milk in TTBS (pH 7.6).
Blocking of endogenous peroxidase activity was achieved using 3% hydrogen peroxide for 10 min, and then sections were blocked using 5% albumin from bovine serum (BSA; Sigma-Aldrich) for 30 min.
In addition, subjects were required to have an Adult Myopathy Assessment Tool (AMAT) 5 score from 14 to 41. Subject group randomization was achieved using stratified block randomization based on AMAT scores with a block size of four.
Blocking of leptin's expression was achieved using siRNA against leptin and transfection with liposomes.
To investigate the importance of OX40 signals for physiological CD4+ T-cell responses, an endogenous antigen-specific population of CD4+ T cells that recognise the 2W1S peptide was assessed and temporal control of OX40 signals was achieved using blocking or agonistic antibodies (Abs) in vivo.
The experiment required reproducible longitudinal alignment of the bone during compression testing, and this was achieved using a mounting block.
A spatial resolution of 1.5 mm was achieved using the optimized partially segmented block detector.
