abstract regeneration is a biological phenomenon, which takes place via two main mechanisms: first, dedifferentiation of mature cells followed by their differentiation into functional new cells and second, activation of endogenous somatic stem cells for regeneration of damaged or lost tissues. one of the best examples of healing process in mammals is the regeneration of damaged pinna in rabbits...

background the somatotype may influence the balance control ability. the quality of balance performance is an important factor to prevent injuries during sport activities. objectives the purpose of this study was to investigate the influence of somatotype on the static and dynamic balance indices as well as falling risk index. patients and methods a total of 141 university student healthy young...

In a recent paper, Robert Hanna argues that Kant’s incongruent counterparts example can be mobilized to show that some mental representations, which represent complex states of affairs as complex, do so entirely non-conceptually. I will argue that Hanna is right to see that Kant uses incongruent counterparts to show that there must be a non-conceptual component to cognition, but goes too far in...

The integrity of data, and transparency about their acquisition, are vital to science. The impact factor data that are gathered and sold by Thomson Scientifi c (formerly the Institute of Scientifi c Information, or ISI) have a strong infl uence on the scientifi c community, affecting decisions on where to publish, whom to promote or hire (1), the success of grant applications (2), and even sala...

patients discussed above had never had out-of-body illusions before, yet direct stimulation of their brain somehow generated experiences quite different from those of everyday life. Is this difference a matter of quality or degree? Many people have had dreams of intense, prolonged falling, even though they have never fallen from such heights before. Perhaps vestibular-somatosensory responses, a...

Pek et al. describe how a stable, intron-derived RNA regulates the expression of its host gene during Drosophila embryogenesis. Once they are spliced out of nascent mRNAs, noncoding intron sequences are usually degraded rapidly. At least in Xenopus eggs and human cell lines, however, some intronic RNAs persist for long periods, although the function of these stable intronic sequence (sis) RNAs ...
