Loss of nbs-1 leads to severely reduced loading of recombinase RAD-51, ssDNA binding protein RPA, and pro-crossover factor COSA-1 during meiotic prophase progression; aggregated and fragmented chromosomes at the end of meiotic prophase; and 100% progeny lethality.
The data therefore implicate Sgs1 as an anti-crossover factor, whose actions are opposed by the pro-crossover activities of the ZMM proteins [54] [56].
A 2 × 4 complex factor crossover design was used.
However, the research, titled Bloodcurdling Movies and Measures of Coagulation: Fear Factor Crossover Trial, attempted to see if this effect could be seen even without physical exertion.
The experimental design was a two factor crossover experiment, i.e. in phase 1, two goats were fed CL and 2 CL and polyethylene glycol (PEG) and in phase 2, the treatments were switched.
I've never been a huge fan of this crossover vehicle form factor, so I wasn't too blown away by the exterior — but the interior packs some tricks that caught my eye.
The tuning parameters include the matrix size for the low-level matrix multiplication, loop unrolling factors, crossover points for different matrix-multiplication implementations, the minimum size for matrices to be transposed, or blocking sizes for the last-level cache.
In a prospective crossover study, 4-factor PCCs failed to correct coagulation times or thrombin generation in humans taking dabigatran [ 15] suggesting that 4-factor PCCs are not useful for dabigatran-associated hemorrhage.
