Finally, recently it has been shown that the chromatin status cells of secretory and absorptive progenitors remain constant. It is likely that throughout the crypt the palette of accessible loci remains unchanged with lineage choice making the restoration

of stemness from maturing cell types purely dependent on expression on key transcription factors [42••]. In confirming the dependency of the epithelium on bHLH family members LY2109761 concentration attention must turn to determining their modes of expression and how these are regulated to achieve different outcomes in different contexts including both in homeostasis and the plasticity associated with regeneration.

“The authors regret that below the subtitle ‘2.7. Determination of the hydrophobic surface’ on page no. 1235 the acronym ANSA has been wrongly abbreviated. The right abbreviation is ANSA = 8-anilino-1-naphthalene

sulfonic acid. Moreover, where it stands: a) “”apparent dissociation constant (kdapp)”", at the abstract, and at the section 3.2 ATP exchange rate is affected by decavanadate, and b) “”Kdapp (micraM)”" GSK126 mouse at the Y-axis of Figs. 3B and 4B, it should be read as “”half-life time (s)”". The authors would like

to apologise for any inconvenience caused. “
“Wave-induced vibration referred to springing and whipping can cause critical problems in a fatigue design of larger and faster merchant ships. It is well known that the problem is due to decreasing natural frequency and increasing forward speed. Particularly, the size of containerships has drastically increased in the past 5–6 years, and it is still increasing. The fatigue until damage induced by springing and whipping can be a major contributor to total fatigue damage for the larger containerships. Many numerical simulations, experiments and full scale measurements have been carried out, and the importance of springing and whipping has been revealed (Storhaug, 2007 and Drummen et al., 2008). The representative early attempt to numerically simulate springing was done by Bishop and Price (1979). A combination of Timoshenko beam and linear strip theory is quite practical and has a potential for more sophisticated methods. Timoshenko beam theory does not cover non-uniform torsion and structural discontinuity, but they can play a role in the torsional responses of containerships. Senjanović et al. (2009a) successfully considered them in the analysis of containerships based on the thin-walled girder theory. A direct way to consider them is to model the whole structure using 3-D FEM.
