The effectiveness of hysteroscopy for the treatment of cesarean scar pregnancy: a retrospective cohort study.

Background: Cesarean scar pregnancy (CSP) is a long-term complication of cesarean section characterized by the localization of a subsequent gestational sac within the scar area or niche developed as a result of a previous cesarean section. Its incidence has increased substantially because of the high global cesarean section rate in recent decades. Several surgical and drug treatments exist for this condition; however, there is currently no optimal treatment.

Mechanisms of sex differentiation and sex reversal in hermaphrodite fish as revealed by the Epinephelus coioides genome.

Most grouper species are functional protogynous hermaphrodites, but the genetic basis and the molecular mechanisms underlying the regulation of this unique reproductive strategy remain enigmatic. In this study, we report a high-quality chromosome-level genome assembly of the representative orange-spotted grouper (Epinephelus coioides). No duplication or deletion of sex differentiation-related genes was found in the genome, suggesting that sex development in this grouper may be related to changes in regulatory sequences or environmental factors.

Quantification of the antagonistic and synergistic effects of Pb, Cu, and Zn bioaccumulation by living Bacillus subtilis biomass using XGBoost and SHAP.

Identification of candidate sex-specific genomic regions in male and female Asian arowana genomes.

Background: Asian arowana, Scleropages formosus, is one of the most expensive aquarium fish species worldwide. Its sex, however, cannot be distinguished clearly at any development stage, which impedes captive breeding and species protection for this endangered aquarium fish.

Results: To discover molecular clues to the sex of Asian arowana, we sequenced 26.

Endemic to Australia, jade perch (Scortum barcoo) is a highly profitable freshwater bass species. It has extraordinarily high levels of omega-3 polyunsaturated fatty acids (PUFAs), which detailed genes involved in are largely unclear. Meanwhile, there were four chromosome-level bass species have been previous sequenced, while the bass ancestor genome karyotypes have not been estimated.

Effects of organic fertilization on functional microbial communities associated with greenhouse gas emissions in paddy soils.

Soil microbial communities play a key role in the biochemical processes and nutrient cycles of the soil ecosystem and their byproducts, including greenhouse gases (GHGs). Organic fertilization influences bacterial soil biodiversity and is an essential emission source of GHGs in paddy soil ecosystems. However, the impact of organic fertilization on the functional microorganisms associated with the GHGs methane and nitrous oxide remains unknown.

Evolutionary Genomics Reveals Multiple Functions of Arylalkylamine -Acetyltransferase in Fish.

As an important hormone, melatonin participates in endocrine regulation of diverse functions in vertebrates. Its biosynthesis is catalyzed by four cascaded enzymes, among them, arylalkylamine -acetyltransferase (AANAT) is the most critical one. Although only single gene has been identified in most groups of vertebrates, researchers including us have determined that fish have the most diverse of genes (, and ), playing various potential roles such as seasonal migration, amphibious aerial vision, and cave or deep-sea adaptation.

Microplastics in the soil: A review of distribution, anthropogenic impact, and interaction with soil microorganisms based on meta-analysis.

Microplastics (MPs) are widespread anthropogenic pollutants that contaminate the terrestrial environment and serve as vectors of other contaminants. They trigger toxic effects during their migration and transmission, affecting the soil ecosystem and eventually presenting a serious threat to human health via the food chain. However, comprehensive studies on the distribution of MPs in soil and their correlation with human activities and terrestrial ecosystems are still lacking.

Temporal dynamics of teleost populations during the Pleistocene: a report from publicly available genome data.

Background: Global climate oscillation, as a selection dynamic, is an ecologically important element resulting in global biodiversity. During the glacial geological periods, most organisms suffered detrimental selection pressures (such as food shortage and habitat loss) and went through population declines. However, during the mild interglacial periods, many species re-flourished.

Balancing selection maintains ancient polymorphisms at conserved enhancers for the olfactory receptor genes of a Chinese marine fish.

The study of balancing selection, as a selective force maintaining adaptive genetic variation in gene pools longer than expected by drift, is currently experiencing renewed interest due to the increased availability of new data, methods of analysis, and case studies. In this investigation, evidence of balancing selection operating on conserved enhancers of the olfactory receptor (OR) genes is presented for the Chinese sleeper (Bostrychus sinensis), a coastal marine fish that is emerging as a model species for evolutionary studies in the Northwest Pacific marginal seas. Coupled with tests for Gene Ontology enrichment and transcription factor binding, population genomic data allow for the identification of an OR cluster in the sleeper with a downstream flanking region containing three enhancers that are conserved with human and other fish species.
