Aim: Efficacy of modern fluoroquinolones for urgent prophylaxis and treatment of experimental glanders was studied. In experiments on laboratory animals in vivo, it was shown that sparfloxacin, gemifloxacin, levofloxacin and moxifloxacin were highly effective for urgent prophylaxis and treatment of glanders.
Materials And Methods: Golden hamsters of both sexes, with weight 80 - 100 g, were inoculated with 100 LD50 of 48-hour agar culture of Burkholderia mallei (strain ts-5). Commercial preparations of 2 - 4th generations of fluoroquinolones: sparfloxacin (Sparflo, India), gemifloxacin (Faktiv, Russia), moxifloxacin (Avelox, Germany), pefloxacin (Abactal, Slovenia), levofloxacin (Eleflox, India), lomefloxacin (Lomeflox, India), ofloxacin (Russia). Urgent prophylaxis started 3 hours after inoculation with duration of 10 days, whereas treatment started 24 hours after inoculation with duration of 15 days. Daily dose of pefloxacin, ciprofloxacin, of loxacin was divided on 2 parts, which were administered with 12-hour interval; other drugswere administered once a day.
Results: All studied drugs, excluding lomefloxacin, were highly effective for urgent prophylaxis and treatment of experimental glanders and provided 80 - 100% protection.
Conclusion: Third-fourth generations of fluoroquinolones: sparfloxacin, levofloxacin, moxifloxacin, gemifloxacin were highly effective against agent of glanders in in vivo experiments. They are promising drugs for the development of schemes for urgent prophylaxis and treatment of glanders in humans.

Accidental ingestion of lead (Pb)-contaminated soils represents a major route of Pb exposure for both adults and children, and the development of accessible and cost-effective solutions to reduce Pb poisoning is urgently required. Here, we present an effective and straightforward technique, involving the consumption of cola beverages, for the purpose of lowering blood Pb levels following the ingestion of contaminated soils in animal models. This method facilitated the direct passage of Pb in contaminated soil through the digestive system, enhancing its elimination without absorption into systemic circulation.

Bacterial-infected wounds usually lead to slow wound healing due to increased inflammation, especially wounds infected by drug-resistant bacteria, which is a serious challenge in the biomedical field. Traditional antimicrobial strategies such as antibiotics lead to a significant increase in drug-resistant strains and have limited efficacy. Therefore, there is an urgent need to develop multifunctional dressings with excellent antibacterial activity and promotion of wound healing.

It is urgent for patients with chronic kidney disease (CKD) to develop a robust and facile therapy for effective control of serum phosphate and reasonable regulation of gut microbiota, which are aiming to prevent cardiovascular calcification and reduce cardiovascular complications. Here, bioinspired by intestinal microstructures, we developed biomimetic wrinkled prebiotic-containing microspheres with enhanced intestinal retention and absorption for reducing hyperphosphatemia and vascular calcification of CKD model rats. The resultant CSM@5 microspheres exhibited favorable phosphate binding capacity in vitro and could effectively reduce serum concentration of phosphorous in vivo.
