37401por Shakes, Diane C., Wu, Jui-ching, Sadler, Penny L., LaPrade, Kristen, Moore, Landon L., Noritake, Alana, Chu, Diana S.“…We find that karyosome formation, in which chromosomes form a constricted mass within an intact nuclear envelope, follows desynapsis, involves a global down-regulation of transcription, and may support the sequential activation of multiple kinases that prepare spermatocytes for meiotic divisions. In spermatocytes, the presence of centrioles alters both the relative timing of meiotic spindle assembly and its ultimate structure. …”

Russell“…Height and weight data were collected from a further 3303 preschool children to establish and validate an extended PZQ dose pole that now includes two new height-intervals: 60–84 cm for one-half tablet and 84–99 cm for three-quarter tablet divisions; which would result in 97·6% of children receiving an acceptable dose (30–60 mg/kg). …”

The latter defect is also observed upon HuR overexpression. …”

The two signals exhibit different sensitivity to sample size and clustering in the half-wavelength regime. …”

During interphase, Brd4 also plays a key role in regulating the transcription of signal-inducible genes by recruiting positive transcription elongation factor b (P-TEFb) to promoters. …”

Life span was unaffected by loss of Ce-emerin alone but was significantly reduced in LEM-2–null animals, and double-null animals had an even shorter life span. …”

These unique properties of the pFCEN plasmid will solve the current technical limitations of the genetic manipulation of P. falciparum, and thus, this plasmid will become a standard genetic tool for the study of this parasite.…”

This allowed us to quantitatively analyze cleavage kinetics of cloned embryos and revealed an extended and inconstant duration of the second and third cell cycles compared to fertilized controls generated by intracytoplasmic sperm injection (ICSI). …”

Cells lacking Cuf2 showed an elevated and sustained expression of several of the middle meiotic genes that persisted even during late meiosis. …”
