The phrase "a single fraction with a" is correct and usable in written English.
It can be used in mathematical contexts or discussions involving fractions, particularly when describing a specific fraction that has a certain property or characteristic.
Example: "In this equation, we need to simplify a single fraction with a common denominator to make the calculations easier."
Alternatives: "one fraction containing a" or "a lone fraction with a".
Brock and colleagues [ 64] treated a murine sarcoma cell line with a single fraction of radiation with and without INO-1001 and found that these cells were radiosensitized by PARP inhibition with an enhancement ratio of 1.7.
Instead of a single fraction that eluted with low concentrations of NaCl, as observed in H. wrightii grown in normal salt concentrations (35 ppt), the sample collected from higher salinity conditions had two additional fractions with a higher degree of sulfation (Fig. 3-A, peaks 3 and 4).
On the other hand, treatments with gamma-knife for CNS tumours and with hadrontherapy for other solid tumours involved doses in excess of 10 15 Gy in a single fraction been used with the intent to cure (Miyamoto et al, 2007; Han et al, 2012).
Now that we have obtained a complex fraction with a single fraction in both the numerator and the denominator, we can use this property of division to simplify our complex fraction!
Two female pigs received a single fraction of 20 Gy with 6-MeV electrons to a 22 × 60 cm field on the dorsal body skin 7 weeks before experimentation.
However, this technique is promising in the elderly, since a single fraction therapy delivered concomitantly with surgery may avoid the inconvenience of several weeks of daily therapy.
Four sites were treated with a single fraction of 750 800 cGy (n = 3) and 8 sites were treated with 4000 4500 cGy in 200 250 cGy fractions (n = 3).
Briefly, all mice (including mice receiving sham radiation) were anaesthetized by intra-peritoneal (i.p.) injection of avertin (240 mg kg−1) and the primary tumours irradiated with a single fraction of 8 Gy, 20 Gy or 30 Gy on day 12 or with 3 fractions of 8 Gy on day 12, 13 and 14 using the Small Animal Radiation Research Platform (SARRP Xstrahl, Surrey, UK).
