Knowledge of the molecular mechanisms of bone formation has been advanced by novel findings related to genetic control. Odd-skipped related 1 (Osr1) is known to play important roles in embryonic, heart, and urogenital development. To elucidate the in vivo function of Osr1 in bone formation, we generated transgenic mice overexpressing full-length Osr1 under control of its 2.

In this study, we analyzed the promoter region of Osr1 to elucidate its regulation mechanism. The mouse Osr1 promoter region was cloned and characterized, and found to have two repressor elements in the -4504/-2766 and -1616/-109 regions, and two enhancer elements in the -2766/-1616 and -109/+199 regions.

We studied whether the H(+) transport mechanism is due to charge transfer and/or transfer of hydronium ion (H(3)O(+)). From transport of [(18)O]H(2)O, 1.

Detection of unruptured aneurysms is a major task in magnetic resonance angiography (MRA). However, it is difficult for radiologists to detect small aneurysms on the maximum intensity projection (MIP) images because adjacent vessels may overlap with the aneurysms. Therefore, we proposed a method for making a new MIP image, the SelMIP image, with the interested vessels only, as opposed to all vessels, by manually selecting a cerebral artery from a list of cerebral arteries recognized automatically.

Our results indicate that Osr2 functions in regulation of osteoblast proliferation.
Introduction: Molecular mechanisms that control bone formation have received attention with increasing knowledge related to genetic control of osteoblast differentiation.
