[Definition 10.2.1] Let f:X\rightarrow \mathbb{R} be a function, and let x_0\in X。 We say that f attains a local maximum at x_0 if and only if there exists a \delta>0 such that the restriction f|X\cap(x_0-\delta,x_0+\delta) of X\cap (x_0-\delta,x_0+\delta) at...
Although sex determination and differentiation are key developmental processes in animals, the involvement of non-coding RNA in the regulation of this process is still not clarified. The tiger pufferfish (Takifugu rubripes) is one of the most economically important marine cultured species in Asia, but...
Here the maternal tudor[1] mutation was tested in a particularly long-lived genetic background, and was found to increase the life span of male offspring, but to have neutral or negative effects on female life span. In the Drosophila soma, sexual differentiation is determined by the X ...
The results show that the XX-XY difference is due to a combination of a Y chromosome effect and an effect of the difference in X chromosome constitution (2X v 1X). The Y effect is not dependent on the presence of Sry. In the light of this and other studies, it is concluded that ...
Sex chromosomes of the Japanese frog Rana rugosa are heteromorphic in the male (XX/XY) or in the female (ZZ/ZW) in two geographic forms, whereas they are still homomorphic in both sexes in two other forms (Hiroshima and Isehara types). To make clear the origin and differentiation mechanism...
This brings to the alternative hypothesis that tumors may originate from differentiated cells that have recovered stem cell properties owing to genetic or epigenetic reprogramming.1,2 Possibly, both models are correct, and consequently there is a continuum of cells capable of generating cancer, ranging...

Impaired differentiation of preadipocytes during cultivation of 3T3-L1 cells. In order to evaluate which stages of adipocyte differentiation required Psmb8 activity, we inhibited immunoproteasome activity using ONX0914, a Psmb8 inhibitor, in different stages of a 3T3-L1 culture system. The 3T3...
