• Type I error, also known as a “false positive”: the error of rejecting a null hypothesis when it is actually true. In other words, this is the error of accepting an alternative hypothesis (the real hypothesis of interest) when the results can be attributed to chance. Plainly speaking, it occurs when we are observing a difference when in truth there is none (or more specifically no statistical...

conclusions the most relevant finding was that hook pinning in pauwels type iii fracture may result in delayed :union: or non:union: due to significantly increased stress of a traction force at the fracture site that works to displace the fracture. however, in a pauwels type i fracture, increased compression stress contributes to stabilize it. surgeons are recommended not to treat pauwels type ...

age related cytochemical changes of thymic endocrine cells were studied in 78 day old chicks at five day interval to age of day 60 employing a panel of cytochemical stains. methenamine silver revealed cell morphology including cell processes distinctly while diamine silver revealed a stronger argentaffinity in these cells. the cells had greater affinity for diamine silver compared to methenamin...

conclusions regarding the results, it could be suggested that the reason for not being able to control diabetes was the existence of differences among viewpoints while by getting to know the obstacles for controlling diabetes from the viewpoints of the three studied groups, more effective planning for controlling diabetes could be possible. results the results of this research showed that there...

introduction: it is essential for clinicians to have knowledge about root canal configuration, although its morphology varies largely in different ethnicities and even in different individuals within the same ethnic group. the current study reviewed the root canal configuration of root canals in mandibular first and second premolars among iranian population based on independent epidemiological ...

Transforming growth factor beta (TGFβ1, β2, and β3) are 25 kDa disulfide-linked homodimers that regulate many aspects of cellular functions, consist of proliferation, differentiation, adhesion and extracellular matrix formation. TGFβs mediate their biological activities by binding of growth factor ligand to two related, functionally distinct, single-pass transmembrane receptor kinases, known as...
