Cell-free fetal DNA (cffDNA) shed from the placenta can be detected in maternal blood and increases incrementally during gestation. Concentrations are further elevated with pregnancy complications. Specific activators of cffDNA release in such complications have not been identified. Ruboxistaurin Here, we use trophoblast cells from early and term placenta to examine cffDNA release following apoptosis, infection, and sterile inflammatory stress.

HTR8/SVneo cells were used to model first-trimester trophoblasts, and term cytotrophoblasts (CTBs) were isolated from placentae collected after uncomplicated deliveries. Trophoblasts were treated with varying concentrations of doxorubicin (DOX), lipopolysaccharide (LPS), or high-mobility group box protein 1 (HMGB1) for 18h. Cells or supernatants were quantified for caspase-3/7cleavage, pro-inflammatory cytokine secretion, and cffDNA release.

Both HTR8/SVneo and CTBs underwent caspase-3/7cleavage following DOX treatment, with HTR8/SVneo cells more sensitive to apoptosis than te and complicated pregnancy can identify new targets for the diagnosis and treatment of gestational complications.Malignant tumor is a disease with high mortality. Traditional treatment methods have many disadvantages, such as side-effects, drug resistance. Because cyclin-dependent kinase 1 (CDK1) plays an indispensable role in cell cycle regulation, it became an attractive target in rational anti-cancer drug discovery. Herein, we reported a series of baicalein derivatives, which remarkably repressed the proliferation of MCF-7 tumor cells and the activity of CDK1/cyclin B kinase. Among them, compound 4a displayed better inhibition rate than flavopiridol against MCF-7 proliferation at the concentration of 50 μg/ml, comparable to compound CGP74514A, while compound 3o possessed the best activity against CDK1/cyclin B kinase (IC50 = 1.26 μM). The inhibitory activities toward the kinase well correlated with anti-proliferative activities. Molecular docking results suggested that compound 3o can interact with the key amino acid residues, E81, L83, and D146, of CDK1 through hydrogen bond just like flavopiridol does. And it can also form an extra hydrogen bond with D146 by its introduced 7-acrylate group, which flavopiridol does not have. These findings proved that baicalein derivatives can be used as CDK1 inhibitors fighting against cancer.

Coronavirus disease 2019 (COVID-19) pandemic has affected the lives of young and old people. Most reports on pediatric cases suggest that children experience fewer and milder symptoms than adults do. This is the first nationwide study that focused on pediatric cases reported by pediatricians, including those with no or mild symptoms, in Japan.

We analyzed the epidemiological and clinical characteristics, and transmission patterns of 840 pediatric (<16 years old) COVID-19 cases reported between February and December 2020 in Japan, using a dedicated database that was voluntarily registered by the members of the Japan Pediatric Society.

Almost half of patients (47.7%) were asymptomatic, while most of the others presented mild symptoms. At the time of admission or first outpatient clinic visit, 84.0% of the cases were afebrile (<37.5°C). In total, 609 cases (72.5%) were exposed to COVID-19-positive household members. We analyzed the influence of nationwide school closures that were introduced in March 2020 on COVID-19 transmission routes among children in Japan. Transmission within households occurred most frequently, with no significant difference between the periods before and after declaring nationwide school closures (70.9% and 74.5%, respectively).

COVID-19 symptoms in pediatric cases are less severe than those in adult cases. School closure appeared to be limitedly effective, and controlling household transmission from adult family members is the most important measure for COVID-19 prevention among children.

The Eyberg Child Behavior Inventory (ECBI) has been considered as one of the standardized parent rating scales which is available to identify disruptive behavior problems in children in Western countries. This study aimed to firstly determine the normative and psychometric data of the Japanese-version of the ECBI, including clinical cutoff scores among the general population in Japan.

This study established norms for the Japanese version of the ECBI in a sample of 1992 parents of children aged 2 to 7, living in Japan. This research evaluates the validity of the reliability (i.e., evaluation of the internal consistency with the assessment of Cronbach's alpha) of the ECBI scores for the Intensity Scale and the Problem Scale. After validation, a clinical cutoff value of the ECBI scores will be calculated and proposed using the same method, setting the cutoff to above the +1SD level based on population distribution, as in the United States, the country where the ECBI was developed.

The means of the Intensity and Problem Scale scores were 100.07 and 6.57, respectively. Cronbach's alpha for both the Intensity and the Problem scores was 0.91. At this point, we propose cutoff scores of 125 for the Intensity Scale and 14 for the Problem Scale.

Our results suggest that the Japanese version of the ECBI has a high reliability and may be useful as a tool for assessing behavior problems in children.

Caudal epidural injections are easy, effective, and safe methods and are good options for patients with low back pain and radicular lower extremity pain. Although various complications related to the technique of the procedure or the drugs used in the procedure have been described, Posterior Reversible Encephalopathy Syndrome (PRES) has not yet been defined for this intervention.

In this case report, we describe a case of PRES, which we supported with MRI findings in our patient who developed convulsions, changes in consciousness, and vision loss after being administered with caudal epidural steroid, and whose imaging findings regressed with the regression of clinical symptoms during the treatment process.

Although PRES is rarely reported, it should be kept in mind that it is a complication that can develop after caudal epidural steroid injection.
