This systematic review and meta-analysis evaluated randomized and nonrandomized studies that assessed the effect of local subgingival propolis as an adjunct to nonsurgical periodontal therapy (NSPT) in the treatment of periodontitis. A detailed search was carried out in Cochrane Library, Embase, LILACS, LIVIVO, PubMed, Scopus, and Web of Science, with no time or language restrictions. A grey literature search was also conducted. The methodology of included studies was evaluated by the Cochrane RoB2 tool. The certainty of each clinical outcome was assessed by the GRADE system. Meta-analyses of mean difference were conducted using the random-effects model, through RevMan 5.4 software. Six studies met the eligibility criteria to be synthesized in the qualitative analysis, and three studies were included in the meta-analysis. The subgingival application of propolis as an adjunct to NSPT improved probing pocket depth (PPD), clinical attachment level (CAL), and bleeding on probing (BOP) in most of the assessed studies. The overall mean difference in PPD reduction was 1.49 mm, 30-45 days after treatment, and 0.8 mm, 90 days after treatment, with very low level of certainty. The overall bias was scored as high risk for all included studies. The adjunctive use of locally delivered propolis associated to NSPT to treat periodontitis may improve periodontal clinical parameters, compared with NSPT alone/placebo. However, the evidence was not strong enough to safely base any clinical recommendation.Invited for the cover of this issue are Satoshi Maeda, Tsuyoshi Mita, and co-workers at ICReDD (Hokkaido University).

The Ca2+ channel, transient receptor potential channel 1 (TRPC1), plays a protective role in regulating entry of Ca2+ activated by store depletion of Ca2+ in endoplasmic reticulum (ER). We have showed that thioredoxin-1 (Trx-1) plays a role in suppressing ER stress in PD. However, whether Trx-1 regulates TRPC1 expression in PD is still unknown. In the present study, we demonstrated that treatment of 1-methyl-4-phenylpyridinum ion (MPP+ ) significantly reduced the expression of TRPC1 in PC12 cells, which was restored by Trx-1 overexpression, and further decreased significantly by Trx-1 siRNA. Moreover, we found that Ca2+ entered into the cells was decreased by MPP+ in PC 12 cells, which was restored by Trx-1 overexpression, and further decreased by Trx-1 siRNA. MPP+ significantly increased calcium-dependent cysteine protease calpain1 expression in PC12 cells, which was suppressed by Trx-1 overexpression. Calpain1 expression was increased by Trx-1 siRNA or SKF96365, an inhibitor of TRPC1. Moreover, 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) decreased TRPC1 expression in the substantia nigra pars compacta region (SNpc), which was restored in mice overexpressing Trx-1, and further decreased in mice of knockdown Trx-1. Inversely, the expression of calpain1 was increased by MPTP, which was suppressed in mice overexpressing Trx-1, and further increased in mice of knockdown Trx-1. In conclusion, Trx-1 regulates the Ca2+ entry through regulating TRPC1 expression after treatment of MPP+ /MPTP.
The rate of labor induction has risen steeply throughout the world. This project aimed to estimate changes in the rates of adverse maternal and neonatal outcomes in Iceland between 1997 and 2018, and to assess whether the changes can be explained by an increased rate of labor induction.

Singleton live births, occurring between 1997 and 2018, that did not start by prelabor cesarean, were identified from the Icelandic Medical Birth Register (n=85971). Rates of intrapartum cesarean birth (CB), obstetric emergencies, and neonatal outcomes were calculated, and adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) were estimated with log-binomial regression (reference 1997-2001). Adjustments were made for (a) maternal characteristics, and (b) labor induction and gestational age.

The rate of labor induction increased from 13.6% in the period 1997-2001 to 28.1% in the period 2014-2018. Selleckchem PFK158 The rate of intrapartum CB decreased between the periods of 1997-2001 and 2014-2018 for both primiparous (aRR 0.76, 95% CI 0.69 to 0.84) and multiparous women (aRR 0.55, 95% CI 0.49 to 0.63). The rate of obstetric emergencies and adverse neonatal outcomes also decreased between these time periods. Adjusting for labor induction did not attenuate these associations.

The rates of adverse maternal outcomes and adverse neonatal outcomes decreased over the study period. However, there was no evidence that this decrease could be explained by the increased rate of labor induction.

Visualization of functional analysis results can help researchers discover relevant biological insights. Despite the availability of many R packages, there lacks interactive and comprehensive graphic systems for displaying functional terms and corresponding genes in meta-omics analysis results. Here, we present ivTerm, an R-shiny package with a user-friendly graphical interface that enables users to inspect functional annotations, compare results across multiple experiments, create customized charts, and download these charts. It provides various basic and innovative chart types to visualize functional terms and involved genes. Users can also browse the description of terms obtained from the database web servers automatically. Two examples, including a metagenome analysis data for human gut and a meta-transcriptome data for coral symbiomes, are given to show the usage of ivTerm.
