Associations between morphokinetic parameters of temporary-arrest embryos and the clinical prognosis in FET cycles.

Infertility is a major health concern worldwide. This retrospective study aimed to assess the predictive value of the morphokinetic parameters of temporary-arrest embryos for the pregnancy outcomes of women undergoing frozen embryo transfer (FET) cycles. In this study, we evaluated 244 FET cycles with 431 day-4 temporary-arrest embryos.

An additional medium renewal of D4 embryo culture improves the concordance of noninvasive chromosome screening with trophectoderm biopsy.

Our research question was to evaluate the chromosome concordance of trophectoderm (TE) biopsy with noninvasive chromosome screening (NICS) using embryo culture medium renewed twice on Day 3 (D3) and Day 4 (D4). In this study, we evaluated 64 cycles with 223 biopsied blastocysts. These were categorized into two groups based on replacing embryo culture medium on D3 (control group) or on D3 and D4 (experimental group).

Medical Arrangement Strategies for Infertility Female Patients during COVID-19 Mini-Outbreak.

LukS-PV Induces Apoptosis the SET8-H4K20me1-PIK3CB Axis in Human Acute Myeloid Leukemia Cells.

Evidence suggests that histone modification disorders are involved in leukemia pathogenesis. We previously reported that LukS-PV, a component of Panton-Valentine leukocidin (PVL), has antileukemia activities that can induce differentiation, increase apoptosis, and inhibit proliferation of acute myeloid leukemia (AML) cells. Furthermore, LukS-PV inhibited hepatoma progression by regulating histone deacetylation, speculating that LukS-PV may exert antileukemia activity by targeting histone modification regulators.

CLDN1 regulates trophoblast apoptosis and proliferation in preeclampsia.

Preeclampsia is a gestational hypertensive disease; however, preeclampsia remains poorly understood. Bioinformatics analysis was applied to find novel genes involved in the pathogenesis of preeclampsia and identified CLDN1 as one of the most differentially expressed genes when comparing patients with preeclampsia and healthy controls. The results of the qRT-PCR, Western blotting and immunohistochemistry experiments demonstrated that CLDN1 was significantly downregulated in the chorionic villi in samples from patients with preeclampsia.

A network meta-analysis protocol of efficacy and safety evaluation of different surgery regimens for varicocele patients with infertility: A study protocol.

Background: Surgical treatment of varicocele is still one of the most common important treatments for male infertility. Surgery regimens for varicocele (VC) is various, including high ligation, sub-inguinal, inguinal, retroperitoneal, laparoscopic, and microsurgery. The surgery regimens applied for VC patients are various in clinic, however, the significance, advantages, and disadvantages of different varicocelectomies for male infertility are still in controversial.

Expert Consensus on Polymyxin Antimicrobial Susceptibility Testing and Clinical Interpretation.

The polymyxins are important antimicrobial agents against antibiotic-resistant gram-negative bacilli. In 2020, the Clinical and Laboratory Standards Institute modified the clinical breakpoints for polymyxin susceptibility test by eliminating the "susceptible" interpretive category, only reporting intermediate (≤2 mg/L) and resistant (≥4 mg/L). However, the European Committee on Antimicrobial Susceptibility Testing recommended the use of clinical breakpoints of ≤2 mg/L as susceptible and >2 mg/L as resistant.

The glucagon-like peptide-1 (GLP-1) analog exenatide ameliorates intrauterine adhesions in mice.

Objective: The purpose of the experiments in this study was to explore the effect of exenatide on intrauterine adhesions (IUAs) and to elucidate its mechanism to provide new ideas for the clinical treatment of IUAs.

Methods: In this study, an animal model of IUAs was established by double stimulation using mechanical curettage and inflammation. After modeling, the treatment group was injected subcutaneously with three doses of exenatide for two weeks.

A conserved double-W box in the promoter of CaWRKY40 mediates autoregulation during response to pathogen attack and heat stress in pepper.

CaWRKY40 was previously found to be transcriptionally up-regulated by Ralstonia solanacearum inoculation (RSI) or heat stress (HS), but the underlying mechanism remains unknown. Herein, we report that a double-W box-element (DWE) in the promoter of CaWRKY40 is critical for these responses. The upstream W box unit WI of this composite element is crucial for preferential binding by CaWRKY40 and responsiveness to RSI or HS.

PDIA3 regulates trophoblast apoptosis and proliferation in preeclampsia via the MDM2/p53 pathway.

Protein disulfide isomerase 3 (PDIA3) is a chaperone protein that modulates the folding of newly synthesized glycoproteins, has isomerase and redox activity, and has been implicated in the pathogenesis of many diseases. However, the role of PDIA3 in pregnancy-associated diseases remains largely unknown. Our present study reveals a key role for PDIA3 in the biology of placental trophoblasts from women with preeclampsia (PE).

Upregulation of RND3 Affects Trophoblast Proliferation, Apoptosis, and Migration at the Maternal-Fetal Interface.

Trophoblasts as the particular cells of the placenta play an important role in implantation and formation of the maternal-fetal interface. RND3 (also known as RhoE) is a unique member of the Rnd subfamily of small GTP-binding proteins. However, its function in cytotrophoblasts (CTBs) at the maternal-fetal interface is poorly understood.

Quantitative proteomic analysis reveals that Luks-PV exerts antitumor activity by regulating the key proteins and metabolic pathways in HepG2 cells.

Hepatocellular carcinoma (HCC) is a complicated and poor prognosis cancer, necessitating the development of a potential treatment strategy. In this study, we initially revealed that LukS-PV belonged to leukocidin family performs an anti-HCC action. Then, we used liquid chromatography-mass spectrometry (LC/MS) to compare protein expression profiles of the LukS-PV-treated human HCC cell lines HepG2 and the control cells.

LncRNA NEAT1 promotes endometrial cancer cell proliferation, migration and invasion by regulating the miR-144-3p/EZH2 axis.

Downregulation of CCNA2 disturbs trophoblast migration, proliferation, and apoptosis during the pathogenesis of recurrent miscarriage.

Problem: Recurrent miscarriage (RM) is defined as two or more pregnancy losses until 24 weeks of gestation, which distresses up to 1-5% of couples worldwide. Cyclin A2 (CCNA2) regulates the cell cycle by promoting transition through G1/S and G2/M. Little is known about CCNA2's functions in trophoblast, although it is highly expressed in the placenta.
