Polycomb repressive complex 2 (PRC2) is an evolutionally conserved multisubunit complex essential for the development of eukaryotes. In Arabidopsis thaliana (Arabidopsis), CURLY LEAF (CLF) and SWINGER (SWN) are PRC2 catalytic subunits that repress gene expression through trimethylating histone H3 at lysine 27 (H3K27me3). CLF and SWN function to safeguard the appropriate expression of key developmental regulators throughout the plant life cycle. Recent researches have advanced our knowledge of the biological roles and the regulation of the activity of CLF and SWN. In this review, we summarize these recent findings and highlight the redundant and differential roles of CLF and SWN in plant development. Further, we discuss the molecular mechanisms underlying CLF and SWN recruitment to specific genomic loci, as well as their interplays with Trithorax-group (TrxG) proteins in plants.

To clarify the role of the ethanol metabolites, ethyl glucuronide (EtG) and ethyl sulfate (EtS), in monitoring alcohol consumption.

We recruited 7 female and 17 male volunteers who were instructed to consume a quantity of beer (containing 48 gm ethanol) with food in one session. We examined urinary excretion of EtG and EtS over time and looked for correlations between the concentrations of the metabolites EtG and EtS.

EtG concentrations in urine varied between 0.026 and 430.372μg/ml with average values between 11.85μg/ml (SD 19.75), 30min after alcohol intake, and 100.39μg/ml (SD 101.34), 4.5h after alcohol intake. Ceftaroline EtS urinary concentration ranged from 0.006 to 101.432μg/ml with average values between 4.77μg/ml (SD 5.42), 30min after alcohol intake, and 30.14μg/ml (SD 27.20), 4.5h after alcohol intake. Spearman's test showed that urinary EtG and EtS correlated significantly at several time points.

The great interindividual variability in their excretion suggests caution in the use of urinary measurement of these metabolites in forensic investigations.

Several transcription factors and miRNAs have been identified as epidermal stem cell markers. However, the separation of epidermal stem cells from their progeny remains challenging. The introduction of single-cell transcriptomics pointed to the high degree of heterogeneity in epidermal stem cells imbedded within subpopulations of keratinocytes. Pseudotime inference, RNA velocity, and cellular entropy further enhanced our knowledge of stem cells, allowing for the discovery of the epidermal stem cell plasticity. We explore the main findings that lead to the discovery of the plastic trait within the epidermal stem cells and the implications of cell plasticity in regenerative medicine.

There is concern about neurodevelopmental outcomes associated with prenatal exposure to valproate and other antiepileptic drugs (AEDs) among children of mothers with or without epilepsy.

To study the risk of intellectual disability and delayed development in childhood milestones among children of women who used valproate or other AEDs during pregnancy.

This population-based cohort study analyzed information on use of AEDs from the Danish National Prescription Registry and register diagnoses from the Danish Psychiatric Central Research Register and Danish National Patient Registry. The study included all live-born singletons in Denmark from January 1, 1997, to December 31, 2011. Data were analyzed in April 2020.

Prenatal exposure to maternal valproate and other AEDs.

The main measures were adjusted Cox regression estimates of hazard ratios (aHRs) for intellectual disability and a combined outcome of intellectual disability with delayed childhood milestones.

A total of 913 302 children (468 708 [51.t women of childbearing potential may need to be counseled on use of AEDs.

Improving care during the postpartum period is a clinical and policy priority. During the comprehensive postpartum visit, guidelines recommend delivery of a large number of assessment, screening, and counseling services. However, little is known about services provided during these visits.

To examine rates of recommended services during the comprehensive postpartum visits and differences by insurance type.

This cross-sectional study included 20 071 093 weighted office-based postpartum visits (645 observations) with obstetrical-gynecological or family medicine physicians from annual National Ambulatory Medical Care Surveys from December 28, 2008, to December 31, 2016, and estimated multivariate regression models to calculate the frequency of recommended services by insurance type, controlling for visit, patient, and physician characteristics. Data analysis was conducted from November 1, 2019, to September 1, 2020.

Visit paid by Medicaid vs other payment types.

Visit length and binary indicators of blrence in visit length or provision of recommended services based on insurance type was a difference in provision of breast examinations (14.7% [95% CI, 8.0%-21.5%] for Medicaid vs 25.6% [95% CI, 19.4%-31.8%] for non-Medicaid; P = .02).

These findings suggest that receipt of recommended services during comprehensive postpartum visits is less than 50% for most services and is similar across insurance types. These findings underscore the importance of efforts to reconceptualize postpartum care to ensure women have access to a range of supports to manage their health during this sensitive period.

Clinical trial evidence used to support drug approval is typically the only information on benefits and harms that patients and clinicians can use for decision-making when novel cancer therapies become available. Various evaluations have raised concern about the uncertainty surrounding these data, and a systematic investigation of the available information on treatment outcomes for cancer drugs approved by the US Food and Drug Administration (FDA) is warranted.

To describe the clinical trial data available on treatment outcomes at the time of FDA approval of all novel cancer drugs approved for the first time between 2000 and 2016.

This comparative effectiveness study analyzed randomized clinical trials and single-arm clinical trials of novel drugs approved for the first time to treat any type of cancer. Approval packages were obtained from drugs@FDA, a publicly available database containing information on drug and biologic products approved for human use in the US. Data from January 2000 to December 2016 were included in this study.
