There is a positive correlation between levels of HOXA-10 and E-cadherin expression in the endometrium, both of which are significantly reduced in women with RIF and RM compared with fertile control women. The findings suggest a potential role of HOXA-10 and E-cadherin in the implantation processes and altered expression in women with reproductive failure.

Soilborne pathogens affect plant growth and food production worldwide. The application of chemical fertilizers and pesticides to control plant diseases has harmful effects; fortunately, plant growth-promoting rhizobacteria can be used as a potential alternative strategy. Here, Paenibacillus jamilae HS-26 was selected for its highly antagonistic activity against several soilborne pathogens. The bacterium synthesized hydrolytic enzymes and released extracellular antifungal metabolites and volatile organic compounds—primarily, N, N-diethyl-1, 4-phenylenediamine, which was detected by gas chromatography-mass spectrometry and shown to inhibit fungal mycelial growth. Furthermore, HS-26 was useful for nitrogen fixation, phosphate and potassium solubilization, and siderophore and indoleacetic acid production. In vitro tests and pot experiments revealed that HS-26 considerably increased plant biometric parameters. Illumina MiSeq sequencing data showed a significant reduction in soilborne pathogens and increase in beneficial bacteria in the wheat rhizosphere after treatment with strain HS-26.

This meta‐analysis aimed to explore the efficiency of intrauterine perfusion of granulocyte colony‐stimulating factor (G‐CSF) on infertile women with thin endometrium. Following PRISMA protocol, we conducted a comprehensive search of academic literatures on various databases including PubMed, EMbase, and Cochrane Library. Studies published in English before July 1, 2016 were included for primary screening. Data on the thickness of endometrium, cycle cancelation rate,clinical pregnancy rate, and embryo implantation rate were extracted and analyzed, respectively. Eleven eligible studies involving 683 patients were included in this meta‐analysis. Compared with control group, G‐CSF perfusion could significantly improve endometrial thickness (mean difference [MD]=1.79, 95% confidence interval (CI): 0.92‐2.67), clinical pregnancy rate (risk ratio [RR]=2.52, 95% CI: 1.39‐4.55), and embryo implantation rate (RR=2.35, 95% CI: 1.20‐4.60), while it could decrease cycle cancelation rate (RR=0.38, 95% CI: 0.25‐0.58). Funnel plots revealed that there was no evidence of publication bias. The current data indicate that intrauterine perfusion of G‐CSF can improve endometrial thickness, clinical pregnancy rate, and embryo implantation rate, but decrease the cycle cancelation rate in women with thin endometrium.

The endometrium becomes receptive to the embryo only in the mid-luteal phase, but not in the other stages of the menstrual cycle. Endometrial factors play an important role in implantation. Women with recurrent miscarriage and recurrent implantation failure have both been reported to have altered expression of receptivity markers during the window of implantation. We aimed to compare the gene expression profiles of the endometrium in the window of implantation among women with unexplained recurrent implantation failures (RIF) and unexplained recurrent miscarriages (RM) by RNA sequencing (RNA-Seq). In total 20 patients (9 RIF and 11 RM) were recruited. In addition 4 fertile subjects were included as reference. Endometrium samples were precisely timed on the 7th day after luteal hormone surge (LH + 7). All the 24 endometrium samples were extracted for total RNA. The transcriptome was determined by RNA-Seq in the first 14 RNA samples (5 RIF, 6 RM and 3 fertile). Differentially expressed genes between RM and RIF were validated by quantitative real-time PCR (qPCR) in all 24 RNA samples (9 RIF, 11 RM and 4 fertile). Transcriptomic profiles of RM and RIF, but not control samples, were separated from each other by principle component analysis (PCA) and support vector machine (SVM). Complementary and coagulation cascades pathway was significantly up-regulated in RIF while down-regulated in RM. Differentially expressed genes and in complement and coagulation cascade pathway between RM and RIF were further validated by qPCR. This study compared endometrial transcriptome among patients with RIF and RM in the window of implantation; it identified differential molecular pathways in endometrium between RIF and RM, which potentially affect the implantation process.

Rhizospheric microorganisms can increase phosphorus availability in the soil. In this regard, the ability of phosphofungi to dissolve insoluble phosphorus compounds is greater than that of phosphate-solubilizing bacteria. The aim of the current study was to identify efficient phosphofungi that could be developed as commercial microbial agents. Among several phosphate-solubilizing fungal isolates screened, strain CS-1 showed the highest phosphorus-solubilization ability. Based on phylogenetic analysis of the internal transcribed spacer region sequence, it was identified as Aspergillus niger. High-performance liquid chromatography analysis revealed that the mechanism of phosphorus solubilization by CS-1 involved the synthesis and secretion of organic acids, mainly oxalic, tartaric, and citric acids. Furthermore, strain CS-1 exhibited other growth-promoting abilities, including efficient potassium release and degradation of crop straw cellulose. These properties help to returning crop residues to the soil, thereby increasing nutrient availability and sustaining organic matter concentration therein. A pot experiment revealed that CS-1 apparently increased the assessed biometric parameters of wheat seedlings, implying the potential of this strain to be developed as a commercial microbial agent. We used Illumina MiSeq sequencing to investigate the microbial community composition in the rhizosphere of uninoculated wheat plants and wheat plants inoculated with the CS-1 strain to obtain insight into the effect of the CS-1 strain inoculation. The data clearly demonstrated that CS-1 significantly reduced the content of pathogenic fungi, including Gibberella, Fusarium, Monographella, Bipolaris, and Volutella, which cause soil-borne diseases in various crops. Strain CS-1 may hence be developed into a microbial agent for plant growth improvement.Electronic supplementary materialThe online version of this article (10.1186/s13568-018-0593-4) contains supplementary material, which is available to authorized users.
