TL;DR: Two multimethod studies indicate that AF is linked to heightened interoceptive sensitivity, and people who were more sensitive to their heartbeats emphasized feelings of activation and deactivation when reporting their experiences of emotion over time more than did those who were less sensitive.
Abstract: People differ in the extent to which they emphasize feelings of activation or deactivation in their verbal reports of experienced emotion, termed arousal focus (AF). Two multimethod studies indicate that AF is linked to heightened interoceptive sensitivity (as measured by performance on a heartbeat detection task). People who were more sensitive to their heartbeats emphasized feelings of activation and deactivation when reporting their experiences of emotion over time more than did those who were less sensitive. This relationship was not accounted for by several other variables, including simple language effects. Implications for the role of interoception in experienced emotion and the validity of self-reported emotion are discussed.

TL;DR: The present analysis completes a cycle of analyses that have determined the four fundamental parameters of cell proliferation: growth fraction, lengths of cell cycle, and phases Q and P and mathematically relates the size of the initial proliferative population to the neuronal population of the adult neocortex.
Abstract: Neurons of neocortical layers II-VI in the dorsomedial cortex of the mouse arise in the pseudostratified ventricular epithelium (PVE) through 11 cell cycles over the six embryonic days 11-17 (E11-E17). The present experiments measure the proportion of daughter cells that leave the cycle (quiescent or Q fraction or Q) during a single cell cycle and the complementary proportion that continues to proliferate (proliferative or P fraction or P; P = 1 - Q). Q and P for the PVE become 0.5 in the course of the eighth cycle, occurring on E14, and Q rises to approximately 0.8 (and P falls to approximately 0.2) in the course of the 10th cycle occurring on E16. This indicates that early in neuronogenesis, neurons are produced relatively slowly and the PVE expands rapidly but that the reverse happens in the final phase of neuronogenesis. The present analysis completes a cycle of analyses that have determined the four fundamental parameters of cell proliferation: growth fraction, lengths of cell cycle, and phases Q and P. These parameters are the basis of a coherent neuronogenetic model that characterizes patterns of growth of the PVE and mathematically relates the size of the initial proliferative population to the neuronal population of the adult neocortex.

TL;DR: The two forms of RNA polymerase II that exist in vivo, phosphorylation (IIO) and nonphosphorylated (IIA), were purified to apparent homogeneity from HeLa cells.
Abstract: The two forms of RNA polymerase II that exist in vivo, phosphorylated (IIO) and nonphosphorylated (IIA), were purified to apparent homogeneity from HeLa cells. The nonphosphorylated form preferentially binds to the preinitiation complex. RNA polymerase II in the complex was converted by a cellular protein kinase to the phosphorylated form.

TL;DR: Future etiological studies on placenta previa must, at the very least, adjust for potentially confounding effects of maternal age, parity, prior Cesarean delivery and abortions.
Abstract: Objective: Several clinical and epidemiologic studies have reported disparate data on the prevalence rate as well as risk factors associated with placenta previa ‐ a major cause of third-trimester bleeding. We performed a systematic literature review and identified 58 studies on placenta previa published between 1966 and 2000. Study design: Each study was reviewed independently by the two authors and was scored (on the basis of established criteria) on method of diagnosis of placenta previa and on quality of study design. We extracted data on the prevalence rate of placenta previa, as well as associations with various risk factors from each study. A meta-analysis was then performed to determine the extent to which different risk factors predispose women to placenta previa. Results: Our results showed that the overall prevalence rate of placenta previa was 4.0 per 1000 births, with the rate being higher among cohort studies (4.6 per 1000 births), USA-based studies (4.5 per 1000 births) and hospital-based studies (4.4 per 1000 births) than among case‐ control studies (3.5 per 1000 births), foreign-based studies (3.7 per 1000 births) and population-based studies (3.7 per 1000 births), respectively. Advancing maternal age, multiparity, previous Cesarean delivery and abortion, smoking and cocaine use during pregnancy, and male fetuses all conferred increased risk for placenta previa. Strong heterogeneity in the associations between risk factors and placenta previa were noted by study design, accuracy in the diagnosis of placenta previa and population-based versus hospital-based studies. Conclusion: Future etiological studies on placenta previa must, at the very least, adjust for potentially confounding effects of maternal age, parity, prior Cesarean delivery and abortions.

TL;DR: It is demonstrated that all of the basal factors coexist in mature initiation complexes but that following nucleotide addition, this complex becomes disrupted.
Abstract: We have analyzed the fate of the RNA polymerase II (RNAPII) general transcription factors during the transition from initiation to elongation using multiple approaches. We demonstrate that all of the basal factors coexist in mature initiation complexes but that following nucleotide addition, this complex becomes disrupted. During this transition, TFIID remains promoter-bound whereas TFIIB, TFIIE, TFIIF, and TFIIH are released. Upon release, TFIIB reassociates with TFIID, reforming the RNAPII docking site, the DB complex. TFIIE is released before formation of the tenth phosphodiester bond. This precedes TFIIH release, which occurrs after the transcription complex reaches +30. TFIIF is unique in that it is the only basal factor detected in the RNAPII elongation complex. Following its release from the initiation complex, TFIIF has the ability to reassociate with a stalled RNAPII.
