Characterization and genetic analysis of two sugarlandviruses: Klebsiella variicola lytic phages vB_PZK-KV7 and vB_PZK-KV23.

Klebsiella variicola, an emerging pathogen, significantly impacts banana production by causing bacterial sheath rot. Research has shown that phages are effective in treating bacterial infections. In this study, two lytic K.

Effect of prophylactic infusion of norepinephrine on the prevention of hypotension during vertebroplasty: a randomized clinical trial.

Background: Transient hypotension is a common occurrence during the implantation of bone cement. This placebo-controlled randomized clinical trial study investigated the effect of prophylactic infusion of norepinephrine on the incidence of hypotension in senior patients who underwent vertebroplasty.

Methods: The trial recruited patients who were greater than or equal to 65 years of age, had an American Society of Anesthesiologist physical status classification of I to III, and underwent vertebroplasty from August 2020 to August 2021 at the Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Nanjing University of Chinese Medicine in China.

Chitosan quaternary ammonium salt-oxidized sodium alginate-glycerol-calcium ion biobased self-healing hydrogels with excellent spontaneous repair performance.

Self-healing hydrogels have attracted wide attention because of their potential applications in various fields. However, the complex processes, environmental requirements, and insufficient functionality limit their practical application. Herein, we synthesized a chitosan quaternary ammonium salt-oxidized sodium alginate-glycerol-calcium ion (HACC-OSA-Gly-Ca) biobased hydrogel with a multi-network structure that exhibits excellent self-healing abilities.

Three-layer core-shell structure of polypyrrole/polydopamine/poly(l-lactide) nanofibers for wound healing application.

Poor wound healing is a very common clinical problem, so far there is no completely satisfactory treatment. Electropsun nanofibrous wound dressings may provide an ideal structure to improve wound healing. Therefore, development of nanofibrous wound dressings with rapid hemostasis, antibacterial and tissue regenerative multi-functions has been a hotspot in the field of skin tissue engineering.
