Klebsiella pneumoniae (Kp) is a human symbiotic opportunistic pathogen capable of causing severe hospital-based infections and community-acquired infections. The problem of antimicrobial resistance (AMR) has become increasing serious over time, posing a major threat to socio-economic and human development. In this study, we explored the global trend of AMR in 1786 strains of Kp isolated between 1982 and 2023.

First, a speed-adjustable device was introduced to rotate the sample for improving heating uniformity. Then, the maximum RF heating rate and uniform temperature distribution of samples were obtained under 160 mm electrode gap, 120 g sample weight, and 14 r/min rotating speed.

Maytansinoid DM1 can be efficiently integrated into albumin nanoparticles, resulting in remarkable alleviation of in vivo drug toxicity and expanding the repertoire of albumin technology available for cancer therapy.
View Article and Find Full Text PDFLiposomal nanoassemblies have been used extensively as carriers for the delivery of both lipophilic and hydrophilic drugs. They represent a mature, versatile technology with considerable potential for improving the pharmacokinetics of drugs. However, the formulation of many chemotherapeutics into liposome systems has posed a significant challenge due to their incompatible physicochemical properties, as was the case with camptothecin-based chemotherapeutics.
