Aspects of Pelvic Floor Protection in Spontaneous Delivery - a Review.

The necessity of increasingly addressing aspects of pelvic floor protection, i.e., prevention of the most frequent female pelvic floor disorders, such as urinary incontinence, faecal incontinence and pelvic organ prolapse, is the result of the steadily improving understanding of the association of pregnancy and delivery with the prevalence of these disorders.

Caesarean Section. Guideline of the DGGG, OEGGG and SGGG (S3-Level, AWMF Registry No. 015/084, June 2020).

This is an official S3-guideline of the German Society of Gynaecology and Obstetrics (DGGG), the Austrian Society of Gynaecology and Obstetrics (ÖGGG) and the Swiss Society of Gynaecology and Obstetrics (SGGG). The guideline contains evidence-based information and recommendations on indications, complications, methods and care associated with delivery by caesarean section for all medical specialties involved as well as for pregnant women. This guideline has adapted information and recommendations issued in the NICE Caesarean Birth guideline.

A checkpoint-independent mechanism delays entry into mitosis after UV irradiation.

When cells are exposed to stress they delay entry into mitosis. The most extensively studied mechanism behind this delay is the DNA-damage-induced G2/M checkpoint. Here, we show the existence of an additional stress-response pathway in that is independent of the classic ATR/Rad3-dependent checkpoint.

Phenotypes of Mutant Cells Indicate that the Escherichia coli Clamp Loader Has a Role in the Restart of Stalled Replication Forks.

The mutation was discovered in connection with a screen for multicopy suppressors of the temperature-sensitive topoisomerase IV mutation The gene for the clamp loader subunits τ and γ, , but not the mutant , was found to suppress (Ts) when overexpressed. Purified mutant protein was found to be functional , and few phenotypes were found apart from problems with partitioning of DNA in rich medium. We show here that a large number of the replication forks that initiate at never reach the terminus in mutant cells.

Analyzing Schizosaccharomyces pombe DNA Content by Flow Cytometry.

Flow cytometry can be used to measure the DNA content of individual cells. The data are usually presented as DNA histograms that can be used to examine the cells' progression through the cell cycle. Under standard growth conditions, fission yeast cells do not complete cytokinesis until after G1 phase; therefore, DNA histograms show one major peak representing cells in G1 (2×1C DNA) and G2 phase (1×2C DNA).

Consequences of abnormal CDK activity in S phase.

Cyclin Dependent Kinases (CDKs) are important regulators of DNA replication. In this work we have investigated the consequences of increasing or decreasing the CDK activity in S phase. To this end we identified S-phase regulators of the fission yeast CDK, Cdc2, and used appropriate mutants to modulate Cdc2 activity.

Cell-cycle analysis of fission yeast cells by flow cytometry.

The cell cycle of the fission yeast, Schizosaccharomyces pombe, does not easily lend itself to analysis by flow cytometry, mainly because cells in G(1) and G(2) phase contain the same amount of DNA. This occurs because fission yeast cells under standard growth conditions do not complete cytokinesis until after G(1) phase. We have devised a flow cytometric method exploiting the fact that cells in G(1) phase contain two nuclei, whereas cells in G(2) are mononuclear.
