Summary: Exposure to maternal obesity during pregnancy can have significant effects on offspring development, which may not be apparent until adulthood. This study investigated how obesity influences gene expression in the endometrium during early pregnancy using a sheep model. The results showed that obesity affects gene expression related to the immune response, adhesion, and angiogenesis in the endometrium. These findings suggest that the peri-implantation endometrium is responsive to maternal obesity and changes in gene expression during early embryogenesis may contribute to developmental programming.

Summary: The contributions of uterine endometrium and embryo in implantation success are still debated. Various measures, such as endometrial receptivity analysis (ERA), endometrial scratch (ES), endometrial microbiome, and intrauterine or intravenous measures, are recommended to improve implantation success. However, there is insufficient evidence to determine the relative importance of endometrium and embryo in implantation success and the utility of these measures, especially with euploid embryos. Evidence suggests that embryos can implant and develop on non-endometrium epithelium. The role of embryo euploidy in implantation success is currently underappreciated.

Summary: RIF is a disorder with an imprecise definition lacking robust scientific basis, presenting significant challenges in diagnosis and treatment. The concept of 'Theoretical Cumulative Implantation Rate' is proposed to determine RIF diagnosis based on objective data. An updated and standardized definition is needed for patient counseling and research planning.

Summary: This study characterized the expression profile of lncRNAs during peri-implantation periods in sheep conceptuses. The analysis identified a total of 8808 lncRNAs, including 3423 novel lncRNAs. Gene ontology analysis revealed enrichment of lncRNA target genes in the respiratory electron transport chain (RETC). The findings suggest that lncRNAs may play a role in regulating RETC during conceptus development in sheep.

Summary: The loss of uterine epithelial progesterone receptor (PGR) is crucial for embryo implantation in both humans and mice. This study reveals that the two major isoforms PGRA and PGRB disrupt embryo implantation through FOXO1 pathways in uterine epithelium, and both regulate the LIF-SGK1-FOXO1 signaling pathway.

Summary: The aim of this study was to evaluate the association between chronic endometritis and uterine endometrium microbiota with repeated implantation failures and recurrent pregnancy losses. The results suggest that chronic endometritis may be involved in the pathophysiology of recurrent pregnancy losses and repeated implantation failures. Lactobacillus iners and Ureaplasma species may be associated with the etiology of chronic endometritis.

Summary: Recurrent implantation failure (RIF) can be caused by uterine factors, male factors, or embryo factors. It is associated with disrupted endometrial receptivity, altered gene expression, immunologic disturbances, and epigenetic alterations. RIF is a heterogeneous condition with varied immune responses, and personalized therapies based on the patient's immune status are being tested.

Summary: Embryo-endometrial communication plays a critical role in successful embryo implantation and pregnancy establishment through the regulation of maternal immune responses. Recent research has highlighted the importance of extracellular vesicles (EVs) and microRNAs in this process, showing that they modulate maternal immune responses and promote cross-communication between the embryo and the endometrium. Exploring the functions and mechanisms of EVs in embryo implantation and pregnancy may provide valuable insights for reproductive medicine and infertility treatments.

Summary: Recent studies have shown that the uterus has its own microbiota, but the composition of endometrial microbiota and its role in a healthy uterine environment are still not well understood. The interaction between endometrial microbiota and the immune system during conception and pregnancy may play a crucial role in reproductive outcomes. This review aims to summarize the molecular mechanisms by which endometrial microbiota interacts with the immune system, and discuss the link between dysbiosis and reproductive disorders.

Summary: The study identifies a highly proliferative population of mesenchymal cells (hPMC) in midluteal human endometrium, potentially serving as novel decidual precursors; hPMC differ from endometrial stromal cells in the expression of genes for prolactin and other decidual transcription factors, and show signs of differentiation into a decidual subpopulation discovered in early pregnancy; recurrent pregnancy loss is associated with depletion of hPMC.

Summary: Efficient noble-metal free electrocatalyst for oxygen evolution reaction (OER) is crucial for large-scale hydrogen production via water splitting. By designing an electrostatic 2D-2D assembly route, researchers successfully synthesized a LDH(+)-Birnessite(-) hybrid catalyst with advanced catalytic activity and excellent stability under industrial hydrogen production conditions. Experimental and computational results show that shifting Fe-3d orbitals in LDH significantly enhances the electron transfer process during OER, leading to improved performance.

Summary: This paper presents a novel synthesis strategy for Bi-based catalyst in CO2 reduction reaction (CO2RR), which successfully synthesized heterostructured Bi/Bi2O3 nanoplates with abundant O vacancies. The catalyst exhibits excellent catalytic activity for CO2RR and high selectivity for formate generation, surpassing most of the state-of-the-art Bi-based catalysts reported to date. The combination of coordination and heterointerface engineering is shown to promote the catalytic activity and selectivity of Bi-based materials for CO2RR.

Summary: Non-noble metal catalyst Fe-Birnessite (Fe-Bir) was synthesized by controlled Fe-(III) intercalation- and docking-induced layer reconstruction, with significantly improved catalytic activity for the oxygen evolution reaction (OER). The Fe-Bir catalyst exhibited lower OER overpotential and Tafel slope compared to other Bir-based catalysts, and it featured active Fe-(III)-O-Mn-(III) centers interfaced with ordered water molecules between neighboring layers. This study reveals a new OER mechanism and highlights the importance of engineering the confined interlayer environment for efficient energy conversion catalysis.

Summary: Efficient noble-metal-free electrocatalysts are crucial for sustainable generation of green hydrogen. In this study, the catalytic performance of transition-metal-based compounds with tuned chemical compositions was comprehensively investigated, revealing the roles of cations and anions in energy conversion reactions. The engineering of transition metal cations led to improved catalytic activity of the formed transition metal oxides toward water oxidation, while the intake of anions on the TMO surface resulted in multifunctional catalysts for urea oxidation and hydrogen evolution reactions. The constructed TMO & PAR;a-TMO/c-TMS exhibited a much lower potential for alkali hydrogen generation than the noble-metal-based system (IrO2 & PAR;Pt).

Summary: This study revealed a significant lack of awareness among young adults in the UK regarding the potential impacts of gym lifestyles and supplementation on male infertility. Men were found to have a concerning lack of concern for their own fertility, with differences in awareness levels between men and women. It was also observed that men were more likely to consider making changes to their behavior if it had a long-term impact on their fertility compared to short-term effects.

Summary: This study investigates the proteomic and phosphoproteomic differences in the endometrium of women with recurrent pregnancy loss (RPL) compared to healthy control women during different phases of the menstrual cycle. The results identify differentially expressed proteins and phosphorylated proteins, and highlight the insulin/cyclic nucleotide signalling pathway and AMPK/mTOR signalling pathway as major contributors to the abnormality of RPL endometrium. The findings provide insights into potential proteins associated with the pathogenesis of RPL and contribute to the identification of potential targets for RPL treatment.
