Oocyte-derived bone morphogenetic protein 15 (BMP15) and growth differentiation factor 9 (GDF9) are key regulators of follicular development. Here we show that these factors control cumulus cell metabolism, particularly glycolysis and cholesterol biosynthesis before the preovulatory surge of luteinizing hormone. Transcripts encoding enzymes for cholesterol biosynthesis were downregulated in bot...

And a disclaimer: I've made lots of changes of variables throughout. Expect some mistakes. I would appreciate hearing about any you find. I want to look at two different topics that have to do with orthogonal polynomials. The first has to do with approximation; the second, with Mellin transforms and zeta functions. If we have an inner product on R[x], we can use Gram-Schmidt to convert {1, x, x...

BACKGROUND/CONTEXT Across the United States, secondary school curricula are intensifying as a growing proportion of students enroll in high-level academic math courses. In many districts, this intensification process occurs as early as eighth grade, where schools are effectively constraining their mathematics curricula by restricting course offerings and placing more students into Algebra I. Th...

OBJECTIVE To determine whether the incidence of apoptosis in mature oocyte cumulus cells changes after insemination related to infertility. DESIGN Prospective study. SETTING Public hospital and university. PATIENT(S) One hundred women undergoing in vitro fertilization and embryo transfer (IVF-ET). INTERVENTION(S) Collection of cumulus cells from IVF-ET cycles with different infertility ...

In this paper, various interactional features of turn-constructional unit (TCU) continuation as realized in Korean conversation through post-predicate elements are analyzed from a conversation-analytic perspective. Formulated increments, serve re-completers by expanding the host TCU after it has reached possible point completion, which is explicitly marked utterance-final verb predicate. many c...
