Screening microorganisms with robust and stable protein expression and secretion capacity.

Robust and stable protein secretion is crucial for efficient recombinant protein production. Here, a novel and powerful platform using split GFP activated droplet sorting (SGADS) has been developed to significantly boost the yields of the protein of interest (POI). The SGADS platform leverages solubilizing peptide P17 and secretory expression in Bacillus subtilis to optimize two split GFP sensors: the P17-GFP1-9/GFP10-POI-GFP11 sensor for assessing protease activity and the P17-GFP1-10/GFP11-POI sensor for measuring secretion capacity.

Hence, this study explored the potential effect of NP-G2-044, a novel fascin inhibitor, in human NSCLC lines and the Lewis lung cancer (LCC) mice model.

[Profiles of Antibiotic Resistance Genes in the Coastal Aquatic Environment of Xiamen City].

The coastal areas and the adjacent islands are the hotspots of human economic and social activities, including urbanization, industrialization, and agricultural practices, which have profound impacts on the ecological environment of the coastal environment. Antibiotic resistance genes （ARGs）, as emerging contaminants, have become hot topics in water ecological security and public concern. However, the profiles of antibiotic resistome in the costal water remain largely unknown, impeding resistome risk assessment associated with coastal environments.

A gradient phage-assisted continuous evolution method for screening suppressor tRNAs in Escherichia coli.

Suppressor tRNAs, notable for their capability of reading through the stop codon while maintaining normal peptide synthesis, are promising in treating diseases caused by premature termination codons (PTC). However, the lack of effective engineering methods for suppressor tRNAs has curtailed their application potential. Here, we introduce a directed evolution technology that employs phage-assisted continuous evolution (PACE), combined with gradient biosensors featuring various PTCs in the M13 gene III.

Objective: To investigate the protective effect and possible mechanisms of vitamin B 6 against renal injury in patients with sepsis. Methods: A total of 128 patients with sepsis who met the entry criteria in multiple centers were randomly divided into experimental (intravenous vitamin B 6 therapy) and control (intravenous 0.9% sodium chloride therapy) groups based on usual care.

COVID-19 vaccination affects short-term anti-coagulation levels in warfarin treatment.

Vaccines against SARS-CoV-2 have been recommended across the world, yet no study has investigated whether COVID-19 vaccination influences short-term warfarin anti-coagulation levels. Patients on stable warfarin treatment who received anti-SARS-CoV-2 vaccination were prospectively enrolled and followed up for three months. INR values less than 10 days before vaccination (baseline), 3-5 days (short-term) and 6-14 days (medium-term) after vaccination were recorded as INR0, INR1, and INR2, respectively.

Directed Evolution of Escherichia coli Nissle 1917 to Utilize Allulose as Sole Carbon Source.

Sugar substitutes are popular due to their akin taste and low calories. However, excessive use of aspartame and erythritol can have varying effects. While D-allulose is presently deemed a secure alternative to sugar, its excessive consumption is not devoid of cellular stress implications.

Effect of an Online Mindfulness-Based Stress Reduction Intervention on Postpandemic Era Nurses' Subjective Well-being, Job Burnout, and Psychological Adaptation.

This study explores the effects of an online mindfulness-based stress reduction intervention on postpandemic era nurses' subjective well-being, job burnout, and psychological adaptation. Previous studies on the psychological adaptability of nurses mainly focused on investigation rather than intervention. Ninety nurses were randomly classified into an intervention or control group.

[Effect of Sparganii Rhizoma-Curcumae Rhizoma-medicated serum on proliferation, apoptosis, and migration of human ectopic endometrial stromal cells: based on JAK2/STAT3 signaling pathway].

Based on the Janus kinase 2/signal transducer and activator of transcription 3(JAK2/STAT3) signaling pathway, this study investigated the effect of medicated serum of Sparganii Rhizoma(SR) and Curcumae Rhizoma(CR) on the proliferation, apoptosis, migration, and secretion of inflammatory factors of ectopic endometrial stromal cells(ESCs). Specifically, human ESCs were primary-cultured. The effect of different concentration(5%, 10%, 20%) of SR-, CR-, and SR-CR combination-medicated serum, and AG490 solution(50 μmol·L~(-1)) on the proliferation of ESCs was detected by methyl thiazolyl tetrazolium(MTT) assay, and the optimal dose was selected accordingly for further experiment.

Circular RNA hsa_circ_0002938 (circCRIM1) promotes the progression of esophageal squamous cell carcinoma by upregulating transcription factor 12.

Growing evidence has indicated that circular RNAs (circRNAs) play crucial roles in the tumorigenesis and progression of diverse malignancies. However, the majority of circRNAs involved in esophageal squamous cell carcinoma (ESCC) remain undefined and the exact functions and underlying mechanisms of circRNAs in ESCC still need further exploration. In this study, we identified a novel onco-circRNA hsa_circ_0002938, derived from the exons of cysteine-rich transmembrane BMP regulator 1 (CRIM1) pre-mRNA, referred to as circCRIM1.

Knockdown of the long non‑coding RNA MALAT1 ameliorates TNF‑α‑mediated endothelial cell pyroptosis via the miR‑30c‑5p/Cx43 axis.

Long noncoding RNAs (lncRNAs) are related to the development of atherosclerosis (AS). However, the role of lncRNA metastasis associated lung adenocarcinoma transcript 1 (MALAT1) in tumor necrosis factor‑α (TNF‑α)‑induced rat aortic endothelial cell (RAOEC) pyroptosis, as well as the underlying mechanisms, remain unclear. RAOEC morphology was assessed using an inverted microscope.

KASP genotyping and semi-quantitation of G275E mutation in the α6 subunit of Thrips palmi nAChR gene conferring spinetoram resistance.

Background: Pesticide resistance is a long-standing and growing problem in the chemical control of invertebrate pests. Molecular diagnostic methods can facilitate pesticide resistance management by accurately and efficiently detecting resistant mutations and their frequency. In this study, the kompetitive allele specific PCR (KASP) approach, a technology for high-throughput single nucleotide polymorphism (SNP) genotyping, is validated as a useful method for characterizing genotypes at a pesticide-resistance locus for the first time.

Comparison of involved-field intensity-modulated radiotherapy combined with S-1 radiotherapy alone for elderly patients with esophageal cancer.
