We propose that rapid eye movement (REM) and slow-wave sleep contribute differently to the formation of episodic memories. REM sleep is important for building up invariant object representations that eventually recur to gamma-band oscillations in the neocortex. In contrast, slow-wave sleep is more directly involved in the consolidation of episodic ...

An increase in intracellular Ca(2+) concentration is essential for oocyte activation. Thus most artificial oocyte-activation methods focus on increasing the Ca(2+) concentration in the oocytes. Recently, full-term development was reported in mice when oocytes were activated with no increase in intracellular Ca(2+) using the Zn(2+) chelator N,N,N',N'-tetrakis(2-pyridylmethyl)ethylenediamine (TPEN). During oocyte ...

During bovine oocyte maturation, a lower density of cumulus cells surrounding oocytes reduces the developmental competence of the oocytes after IVF. Adding more cumulus cells (Hashimoto et al. 1998) rescues the developmental competence of the corona-enclosed oocytes. In this study, we examined the effects of poly(dimethylsiloxane) (PDMS) microwells (MW) for ...

Recent advances in molecular profiling have shown that cancers arising from the ovary are phenotypically and genetically heterogeneous. Within histologies, many mutations in druggable targets are uncommon in frequency but mutations leading to activation of specific signal transduction pathways are common. These results support the notion that different targeted agents ...

Although the analogy between dreams and ancient mnemotechniques is tempting because they share several phenomenological characteristics, this analogy is superficial at a closer look. Unlike mneomotechnically encoded material, rapid eye movement (REM) dreams are inherently difficult to remember, do not usually allow conscious subsequent retrieval of all interconnected elements, and ...

I contend that Kurzban et al.'s model is silent on three issues. First, the extent to which opportunity-cost computations are automatic or deliberative is unclear. Second, the role of individual differences in biasing opportunity-cost computations needs elucidating. Third, in the absence of "next-best" tasks, task persistence will be indefinite, which ...

The cryopreservation of equine expanded blastocysts (>300μm) has been largely unsuccessful primarily due to the low permeability of the embryo to cryoprotectants. This low permeability has been attributed to the acellular glycoprotein capsule that develops when an embryo approaches approximately 300μm in diameter. Mechanical alternatives may provide a means to ...

Mammalian differentiation is obtained through epigenetic regulations that shape the genome, which is identical in all cells, to distinct phenotypes and tissue specific identities. The differentiated state of mature cells in an adult organism is therefore acquired through epigenetic restrictions that lead to a gradual loss of differentiative potency. In ...
