NETs exacerbate placental inflammation and injury through high mobility group protein B1 during preeclampsia.

Background: Inflammatory stress at the maternal-fetal interface plays an important role in the occurrence and development of preeclampsia(PE) caused by different etiologies. Many pathological neutrophil extracellular traps (NETs) at the maternal-fetal interface are believed to be among the main pathogenic factors leading to preeclampsia and the worsening of its symptoms. However, the underlying mechanism is largely unclear.

WD repeat domain 5 promotes the development of late-onset preeclampsia by activating nuclear factor kappa B.

Purpose: Over-activation of nuclear factor kappa B (NF-κB) was proven to be involved in the pathogenesis of preeclampsia. However, its regulation mechanism is not clear yet. This paper explored the role of WD repeat domain 5 (WDR5) in the development of late-onset preeclampsia and its relationship with NF-κB.

Prediction of Prognosis and Immunotherapy Response with a Novel Natural Killer Cell Marker Genes Signature in Osteosarcoma.

Natural killer (NK) cells are characterized by their antitumor efficacy without previous sensitization, which have attracted attention in tumor immunotherapy. The heterogeneity of osteosarcoma (OS) has hindered therapeutic application of NK cell-based immunotherapy. The authors aimed to construct a novel NK cell-based signature to identify certain OS patients more responsive to immunotherapy.

Preeclampsia-associated lncRNA FEZF1-AS1 regulates cell proliferation and apoptosis in placental trophoblast cells through the ELAVL1/NOC2L axis.

Background: LncRNAs have been shown to be involved in and control the biological processes of multiple diseases, including preeclampsia (PE). The impairment of trophoblast cell proliferation is recognized as a significant anomaly contributing to the development of PE. LncRNA FEZF1-AS1 was found downregulated in placental tissues of PE patients.

Modified fixation for periprosthetic supracondylar femur fractures: Two case reports and review of the literature.

Background: Periprosthetic supracondylar femoral fractures (PSFs) present a challenge in terms of optimizing fixation in patients with poor bone quality. Surgical treatment and peri-operative management of PSFs in the elderly remain a burden for orthopedic surgeons. Among different treatment options, locking plate (LP) and retrograde intramedullary nail (RIMN) have shown favorable results.

miR-101-3p contributes to the progression of preeclampsia by suppressing WDR5-mediated proliferation and invasion of trophoblast.

Background: Decreased proliferation and invasion of trophoblast were proven to be involved in the pathogenesis of preeclampsia (PE). However, the regulatory network has not been clarified yet. This study aimed to explore the role of miR-101-3p in the progression of PE.

Efficacy of intrauterine Bakri balloon tamponade combined with ascending uterine artery ligation on postpartum hemorrhage.

Objective: To observe the efficacy of intrauterine Bakri balloon tamponade (IBBT) combined with ascending uterine artery ligation (AUAL) in the treatment of postpartum hemorrhage (PPH) due to uterine inertia after cesarean section.

Methods: A total of 92 patients with PPH due to uterine inertia after cesarean section were divided into a study group (n=46) and a control group (n=46) in accordance with the random number table. The control group was treated with IBBT alone, while the study group was treated with IBBT combined with AUAL.

Planning priority conservation areas for biodiversity under climate change in topographically complex areas: A case study in Sichuan province, China.

Identifying priority conservation areas plays a significant role in conserving biodiversity under climate change, but uncertainties create challenges for conservation planning. To reduce uncertainties in the conservation planning framework, we developed an adaptation index to assess the effect of topographic complexity on species adaptation to climate change, which was incorporated into the conservation framework as conservation costs. Meanwhile, the species distributions were predicted by the Maxent model, and the priority conservation areas were optimized during different periods in Sichuan province by the Marxan model.

Identification of CDCA8, DSN1 and BIRC5 in Regulating Cell Cycle and Apoptosis in Osteosarcoma Using Bioinformatics and Cell Biology.

Introduction: Osteosarcoma is the most common primary tumor of bone, although some molecular markers have been identified, the detailed molecular mechanisms underlying osteosarcoma are currently not fully understood. In the present study, we attempted to identify the potential key genes and pathways in osteosarcoma using bioinformatics analysis.

Methods: GSE14359 was downloaded from the GEO database, and analyzed using Limma package.

Research on Focal Length Measurement Scheme of Self-Collimating Optical Instrument Based on Double Grating.

In this paper, we propose a scheme for measuring the focal length of a collimating optical instrument. First, a mathematical model for measuring the focal length of a collimator with double gratings is derived based on the moiré fringe formula and the principles of geometric optics. Mathematical simulation shows that a slight difference in the focal length of two collimators has an important influence on the imaging law of moiré fringes.

Chronic sciatic nerve compression induces fibrosis in dorsal root ganglia.

In the present study, pathological alterations in neurons of the dorsal root ganglia (DRG) were investigated in a rat model of chronic sciatic nerve compression. The rat model of chronic sciatic nerve compression was established by placing a 1 cm Silastic tube around the right sciatic nerve. Histological examination was performed via Masson's trichrome staining.

De novo assembly and characterization of the global transcriptome for Rhyacionia leptotubula using Illumina paired-end sequencing.

Background: The pine tip moth, Rhyacionia leptotubula (Lepidoptera: Tortricidae) is one of the most destructive forestry pests in Yunnan Province, China. Despite its importance, less is known regarding all aspects of this pest. Understanding the genetic information of it is essential for exploring the specific traits at the molecular level.

Objective: To analyze the chemical constituents of volatile oil from the rhizomes and leaves of Pileostegia viburnoides var. glabrescens by GC-MS.

Methods: The volatile oil was extracted from the rhizomes and leaves of Pileostegia viburnoides var.

Mitochondrial genome of the pine tip moth Rhyacionia leptotubula (Lepidoptera: Tortricidae).

The complete nucleotide sequence of the mitochondrial genome of the pine tip moth Rhyacionia leptotubula (Lepidoptera, Tortricidae) was determined. The entire genome is 15,877 bp in length, encoding the standard set of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and an A+T-rich control region. The gene order is typical of Lepidoptera and differs from the insect ancestral type in the location of trnM.
