Disseminated organ and tissue infection secondary to carbapenem-resistant Klebsiella pneumoniae bloodstream infection for acute lymphoblastic leukemia treated with ceftazidime-avibactam: Two case reports.

Rationale: Carbapenem-resistant Klebsiella pneumoniae (CRKP) bloodstream infections are a severe complication resulting from granulocyte deficiency following chemotherapy for hematologic malignancies and have a high mortality rate. However, reports of disseminated organ infections secondary to bloodstream infections are rare.

Patient Concerns And Diagnoses: We report 2 cases of patients with acute lymphoblastic leukemia who both developed CRKP bloodstream infections during the granulocyte deficiency stage following chemotherapy, with 1 case of secondary bacterial liver abscess and 1 case of secondary septic arthritis.

Residents' willingness and awareness to participate in internet+nursing service in China: A meta-analysis.

Formamidine as an Easy-On and Easy-Off Linker for Reversible Crosslinking of Two Alkyl Amines in Peptide Stapling and Conjugation.

Amino groups are abundant in both natural and synthetic molecules, offering highly accessible sites for modifying native biorelevant molecules. Despite significant progress with more reactive thiol groups, methods for connecting two amino groups with reversible linkers for bioconjugation applications remain elusive. Herein, we report the use of oxidative decarboxylative condensation of glyoxylic acid to crosslink two alkyl amines via a compact formamidine linkage, applicable in both intra- and intermolecular contexts.

DNA Tetrahedron Reformative Lateral Flow Assay for Improved Detection Sensitivity and Anti-Interference.

The lateral flow assay is a strip-based analytical method for the portable and convenient detection of analytes of interest. It has the advantages of visual observation, autonomous sample flow, fast coloration time, minimal tedious operation procedures, and reliance on specialized instruments. However, the rough surface of the nitrocellulose membrane renders it difficult for the immobilized nucleic acids to remain in an ordered arrangement, and the immobilized nucleic acids are also liable to be digested in a complex matrix, inducing limited sensitivity and anti-interference.

sp. SI-NJAU-1 and Its Mutant Strain with Excretion-Ammonium Capability Promote Plant Growth through Biological Nitrogen Fixation.

Legumes are well-known for symbiotic nitrogen fixation, whereas associative nitrogen fixation for nonlegume plants needs more attention. Most associative nitrogen-fixing bacteria are applied in their original plant species and need further study for broad adaptation. Additionally, if isolated nitrogen-fixing bacteria could function under fertilizer conditions, it is often ignored.

Resistive memory-based zero-shot liquid state machine for multimodal event data learning.

The human brain is a complex spiking neural network (SNN) capable of learning multimodal signals in a zero-shot manner by generalizing existing knowledge. Remarkably, it maintains minimal power consumption through event-based signal propagation. However, replicating the human brain in neuromorphic hardware presents both hardware and software challenges.

Time-domain signatures of distinct correlated insulators in a moiré superlattice.

Among expanding discoveries of quantum phases in moiré superlattices, correlated insulators stand out as both the most stable and most commonly observed. Despite the central importance of these states in moiré physics, little is known about their underlying nature. Here, we use pump-probe spectroscopy to show distinct time-domain signatures of correlated insulators at fillings of one (ν = -1) and two (ν = -2) holes per moiré unit cell in the angle-aligned WSe/WS system.

Lithium complexing strategy based on host-guest recognition for efficient Mg/Li separation.

Ion selective membranes with precise Mg/Li separation have attracted extensive interest in lithium extraction to circumvent the lithium supply shortage. However, realizing this target remains a significant challenge mainly due to a high concentration ratio of Mg/Li as well as the relatively close ionic hydration radius and chemical. Herein, inspired by the host-guest recognition between alkali-metal ions and crown ether (CE), a novel approach was proposed to regulate the membrane internal structure by introducing CE to strengthen the complexation between Li and CE.
