Characterization and Performance Testing of an Intumescent Nanoinhibitor for Inhibiting Coal Spontaneous Combustion.

Considering disadvantages such as the low thermal stability and environmental pollution of existing gel inhibitors, a green and stable intumescent nanoinhibitor (INI) was prepared and tested. First, polyacrylamide (PAM), nano-silica, and intumescent flame retardant (IFR) were selected as raw materials. The INI was prepared by nanoparticle modification and cross-linking polymerization.

Pregnancy outcomes in patients with late-onset severe OHSS following different methods of ascetic fluid drainage and a comparison with non-OHSS IVF patients.

Purpose: In this study, we aimed to identify whether there are any differences in pregnancy outcomes in patients with severe ovarian hyperstimulation syndrome (OHSS) following the drainage of ascites by central venous catheter or paracentesis. We also aimed to identify differences in pregnancy outcomes between severe OHSS patients and non-OHSS IVF patients.

Methods: This was a retrospective cohort analysis carried out in a university-affiliated reproductive center between 2012 and 2019 featuring 359 women with severe OHSS following ascites draining and 345 non-OHSS women (matched by age and the number of oocytes retrieved).

[Correlation of stigma with marital adjustment in female patients undergoing artificial insemination with donor sperm].

Objective: To investigate the stigma and marital adjustment of the female patients undergoing artificial insemination with donor sperm (AID) and analyze their correlation.

Methods: Using the convenience sampling method, we selected 208 infertile female patients undergoing AID from March to December 2020. We conducted a cross-sectional survey among the patients with General Information Questionnaire, Infertility Stigma Scale (ISS), and Dyadic Adjustment Scale (DAS).

Acute miliary tuberculosis in pregnancy after in vitro fertilization and embryo transfer: a report of seven cases.

Background: While miliary tuberculosis (TB) in pregnancy is rare after in vitro fertilization and embryo transfer (IVF-ET), it poses a serious threat to the health of pregnant women and their fetuses. The present study aimed to describe the clinical features of miliary TB and pregnancy outcomes of patients after IVF-ET.

Methods: Data of infertile patients who received IVF-ET at Peking University Third Hospital between January 2012 and December 2017 were retrospectively analyzed.

Fertility quality of life (FertiQoL) among Chinese women undergoing frozen embryo transfer.

Background: Women undergoing infertility treatment have poor quality of life. This may cause them to withdraw from or refuse treatment. Women undergoing frozen embryo transfer have a treatment interval.

Clinical applications of MARSALA for preimplantation genetic diagnosis of spinal muscular atrophy.

Conventional PCR methods combined with linkage analysis based on short tandem repeats (STRs) or Karyomapping with single nucleotide polymorphism (SNP) arrays, have been applied to preimplantation genetic diagnosis (PGD) for spinal muscular atrophy (SMA), an autosome recessive disorder. However, it has limitations in SMA diagnosis by Karyomapping, and these methods are unable to distinguish wild-type embryos with carriers effectively. Mutated allele revealed by sequencing with aneuploidy and linkage analyses (MARSALA) is a new method allowing embryo selection by a one-step next-generation sequencing (NGS) procedure, which has been applied in PGD for both autosome dominant and X-linked diseases in our group previously.
