Human TBCD (HsTBCD) has been reported to behave differently when overexpressed to the bovine protein (BtTBCD) [24], which was the first TBCD isolated and has therefore been more often studied in vitro and in vivo [6], [8].
H pylori eradication was more often studied in regions such as China, South Korea, southern Europe, and the Middle East, with relatively few in other areas.
15 16 Such designs are more often used for studies of large-scale programmes, policies or regulatory changes than for studying smaller projects, although many such large-scale changes include local projects.
First, associations may only be evident where exposure is high; for example, associations with birth weight are more often reported in study populations with higher background exposure to PCBs [ 34].
As some characteristics are correlated (e.g. mortality studies are often prospective, US studies are more often prospective than elsewhere, and studies using lung function criteria are commonly cross-sectional) it is not straightforward to identify underlying effects.
Cis-eQTL tend to have larger effect sizes [ 6], are more often replicated across multiple studies [ 7] and more likely to reflect a direct functional relationship between the SNP and the measured expression levels.
While the first method is mainly adopted by psycholinguistic studies, the latter two are more often used in computer science studies.
Problems related to this group of students, however, are more often linked to a lack of studying skills and less often to motivational problems.
Previous studies have shown that patients who drop out from a trial or a field study are more often distressed and have a decreased quality of life compared with the 'completers' (Houborg et al, 2006).
The trend is now changing and patients with metastatic disease to the CNS are more often eligible to participate in studies, including early clinical trials.
