The oral cavity, pharynx, and larynx may be filled with blood, secretions, soft tissue, and bone fragments, all of which preclude a good view of the vocal cords.
Furthermore, the short lives of radioisotopes require that a cyclotron and onsite radiochemist be present, all of which preclude PET's inclusion into routine clinical assessment of angiogenesis.
Our data is limited by its small sample size and loco-regional disease control within the treatment field in all patients, both of which preclude any useful correlation with outcome.
Serum-derived NB may therefore originate from the direct chemical binding of calcium or apatite to calcification inhibitors normally present in the serum that then become seeds for further apatite precipitation and self-aggregation, all of which precludes the need for any proliferation dependent on cell growth or viability.
Many statistical study designs from the 1960s and 1970s were drawn up to analyse and assess childhood schizophrenia and its causes, all of which precluded the possibility of hallucinatory thought in infants.
We also excluded 481 women with foreign addresses outside the United States, U.S. military, U.S. protectorate, Hawaiian, Alaskan, or missing addresses at the time of randomization or their event, all of which precluded estimation of PM exposures; a total of 26,450 women were included in the PM10 analyses.
Posterior regeneration requires the presence of the intestine, removal of which precludes the formation of hind segments.
NKCC1, via its direct contribution to brain water accumulation, thus represents a promising pharmacological target in brain pathologies involving disturbed water dynamics and increased intracranial pressure, the lack of which precludes efficient pharmacological treatment of a range of patients.
Journalists were barred from the wedding (except for a last minute glimpse at the floral displays), and participants refused interviews, none of which precluded the press from covering the story from the preparations to the honeymoon.
MATER (Maternal antigen that embryos require; official name Nlrp5) is one of the first characterized maternal effect proteins in mice, the absence of which precludes embryonic progression beyond the 2-cell stage [ 7].
Low concentrations of the H-FLBZ metabolite were detected in plasma between 18 and 48 h after the administration of FLBZ in all experimental animals, which preclude any pharmacokinetic analysis.
