We developed one-step sequence- and ligation-independent cloning (SLIC) as a simple, cost-effective, time-saving, and versatile cloning method. Highly efficient and directional cloning can be achieved by direct bacterial transformation 2.5 min after mixing any linearized vector, an insert(s) prepared by PCR, and T4 DNA polymerase in a tube at room temperature.

Background: Acinetobacter baumannii, particularly carbapenem-resistant strains (CRAB), poses a major concern in the fight against antimicrobial resistance (AMR), identified as a top-priority pathogen by the World Health Organization (WHO). A. baumannii has intrinsic resistance to several antibiotics, including penicillin, cephalosporins, chloramphenicol, and fosfomycin, but the development of AMR has led to the emergence of extremely drug-resistant and pan-resistant isolates.

Introduction: The widespread clinical and environmental dissemination of successful clones of carbapenem-resistant (CRKP) represents a serious global public health threat. In this context, lytic bacteriophages have emerged as a promising alternative for controlling these pathogens. This study describes the biological, structural, and genomic characteristics of lytic bacteriophages against the high-risk CRKP clones CG258 and ST307 and describes their performance in combination.

In industry, the two important nitrile starting materials, adiponitrile and 2-methylglutaronitrile, are primarily manufactured through the well-known DuPont process, which consists of a tandem sequence including first hydrocyanation, isomerization and second hydrocyanation. However, this mature process has the intrinsic defects of step efficiency and regioselectivity. Herein, we report a nickel-catalyzed divergent, one-step double hydrocyanation of 1,3-butadiene to produce either adiponitrile or 2-methylglutaronitrile in high regioselectivity.

The pipeline for new drugs against multidrug-resistant remains limited, highlighting the urgent need for innovative treatments. New strategies, such as membrane-targeting molecules acting as adjuvants, aim to enhance antibiotic effectiveness and combat resistance. RW01, a cyclic peptide with low antimicrobial activity, was selected as an adjuvant to enhance drug efficacy through membrane permeabilization.

Background: Spinal cord injury (SCI) inflicts a severe burden on patients and lacks effective treatments. Owing to the poor regenerative capabilities of endogenous oligodendrocyte precursor cells (OPCs) following SCI, there is a growing interest in alternative sources, such as human umbilical cord mesenchymal stem cells (HUCMSCs). TET3 is a key DNA demethylase that plays an important role in neural differentiation, but its role in OPC formation is not well understood.
