Advances in the study of LNPs for mRNA delivery and clinical applications.

Messenger ribonucleic acid (mRNA) was discovered in 1961 as an intermediary for transferring genetic information from DNA to ribosomes for protein synthesis. The COVID-19 pandemic brought worldwide attention to mRNA vaccines. The emergency use authorization of two COVID-19 mRNA vaccines, BNT162b2 and mRNA-1273, were major achievements in the history of vaccine development.

Erythroid-intrinsic activation of TLR8 impairs erythropoiesis in inherited anemia.

Inherited non-hemolytic anemia is a group of rare bone marrow disorders characterized by erythroid defects. Although concerted efforts have been made to explore the underlying pathogenetic mechanisms of these diseases, the understanding of the causative mutations are still incomplete. Here we identify in a diseased pedigree that a gain-of-function mutation in toll-like receptor 8 (TLR8) is implicated in inherited non-hemolytic anemia.

Halomonas rhizosphaerae sp. nov. and Halomonas kalidii sp. nov., two novel moderate halophilic phenolic acid-degrading species isolated from saline soil.

Four vanillic acid-degrading bacterial strains, named LR5S13, LR5S20, and M4R5S39 and LN1S58, were isolated from Kalidium cuspidatum rhizosphere and bulk soils, respectively. Phylogenetic analysis based on 16S rRNA gene as well as core genome revealed that LR5S13 and LR5S20 clustered closely with each other and with Halomonas ventosae Al12, and that the two strains shared the highest similarities (both 99.3 %) with H.

Therefore, developing a predictive risk model for subsequent BSI in hematological patients with CRE isolated from perianal swabs could be used to guide preventive strategies.

Methods: This was a single-center retrospective cohort study at a tertiary blood diseases hospital, including all hematological patients hospitalized from 10 October 2017 to 31 July 2021.

Heterologous expression and characterization of Bacillus velezensis SW5 serine protease involved in the hydrolysis of anchovy protein.

Background: Bacillus velezensis SW5, with good enzyme production ability, was isolated and identified in our laboratory from fermented fish sauce. Its galactosidase has been expressed in Escherichia coli, which could hydrolyze lactose in milk. The present study aims to express a novel serine protease gene (SPr-SW5) of this strain by Bacillus subtilis WB800N, and applies the expressed enzyme in hydrolysis of anchovy to prepare antioxidant substances, aiming to alleviate the waste of low-value fish resources.

Surfactant recovery and efficient separation of PAHs from surfactant solutions by low-cost waste activated sludge and two-stage design optimization.

The treatment and surfactant recovery of soil washing/flushing effluent containing high levels of surfactants and organic pollutants are critical for the surfactant-assisted remediation of soils and waste management due to their complexity and high-potential risks. Combination of waste activated sludge material (WASM) and a kinetic-based two-stage system design was introduced in this study as a novel strategy for the separation of phenanthrene and pyrene from Tween 80 solutions. The results showed that WASM can effectively sorb phenanthrene and pyrene with high affinities (K) of 2325.

Overexpression of lncRNA A2M-AS1 inhibits cell growth and aggressiveness regulating the miR-587/bone morphogenetic protein 3 axis in lung adenocarcinoma.

Lung adenocarcinoma (LUAD) is a malignant tumor that occurs in the lungs. Numerous reports have substantiated the participation of long non-coding RNAs (lncRNAs) in the tumorigenesis of LUAD. Previously, lncRNA alpha-2-macroglobulin antisense RNA 1 (A2M-AS1) was confirmed to be an important regulator in the biological processes of LUAD and dysregulation of A2M-AS1 was associated with non-small cell lung cancer (NSCLC) progression.

Knockdown of Long Noncoding RNA LINC00240 Inhibits Esophageal Cancer Progression by Regulating miR-26a-5p.

Background: Esophageal cancer is the most prevalent digestive system tumor. Due to a lack of characteristic symptoms and early diagnosis, a confirmed esophageal cancer is typically detected at a progressively harmful stage. Therefore, it is critical to investigate the molecular mechanisms governing the formation and progression of esophageal cancer in order to identify new treatment targets for esophageal cancer early detection.

Comprehensive analysis to identify a novel PTEN-associated ceRNA regulatory network as a prognostic biomarker for lung adenocarcinoma.

Lung adenocarcinoma (LUAD) is one of the most prevalent forms of lung cancer. Competitive endogenous RNA (ceRNA) plays an important role in the pathogenesis of lung cancer. Phosphatase and tensin homolog (PTEN) is one of the most frequently deleted tumour suppressor genes in LUAD.

Research Progress in Elucidating the Mechanisms Underlying Resveratrol Action on Lung Cancer.

Resveratrol has several functions, including protection of the heart and nervous system and exerts antidiabetic, anti-inflammatory, anti-aging, and antitumor effects. It is reported to impede the occurrence and development of tumors in cancer cell lines, animal models, and clinical studies. In vitro and in vivo experiments show that it exerts preventive or adjuvant therapeutic effects in pancreatic, colorectal, prostate, liver, and lung cancers.

Risk factors associated with hemorrhagic cystitis after allogeneic hematopoietic stem cell transplantation.

Hemorrhagic cystitis (HC) is a common complication of allogeneic hematopoietic stem cell transplantation (HSCT). The incidence is about 7% to 68%, and some patients have to suffer a long period of frequent, urgent, and painful urination, which brings great pain. This study aimed to analyze risk factors of HC and its effect on patient survival.

Single-cell transcriptomic analysis identifies an immune-prone population in erythroid precursors during human ontogenesis.

Nonimmune cells can have immunomodulatory roles that contribute to healthy development. However, the molecular and cellular mechanisms underlying the immunomodulatory functions of erythroid cells during human ontogenesis remain elusive. Here, integrated, single-cell transcriptomic studies of erythroid cells from the human yolk sac, fetal liver, preterm umbilical cord blood (UCB), term UCB and adult bone marrow (BM) identified classical and immune subsets of erythroid precursors with divergent differentiation trajectories.

Optimizing autologous hematopoietic stem cell transplantation for acute leukemia.

Autologous hematopoietic stem cell transplantation (ASCT) remains an important postremission treatment for acute leukemia (AL). It is known that some prognostic factors, such as age, cytogenetic and molecular risk stratification, and minimal residual disease (MRD) status, are closely related to clinical outcomes following ASCT. Moreover, there are multiple measurements, including pretransplant treatment, stem cell mobilization and collection, conditioning regimens, and maintenance treatment after transplantation, that can affect prognosis after ASCT.
