The noble gas argon is one of the most promising neuroprotective agents for hypoxic-reperfusion injuries of the brain. However, its effect on traumatic injuries has been insufficiently studied. The aim of this study was to analyze the effect of the triple inhalation of the argon-oxygen mixture Ar 70%/O 30% on physical and neurological recovery and the degree of brain damage after traumatic brain injury and to investigate the possible molecular mechanisms of the neuroprotective effect.

- In the context of rising antibiotic resistance, managing infection sources and timely drainage removal is crucial.
- A clinical case is discussed involving a 42-year-old patient with various complications, including a urinary stent that led to an infection from pan-resistant Klebsiella pneumonia.
- The patient's severe condition, including septic shock and coagulation issues, was effectively treated with personalized local bacteriophage therapy.
Data are accumulating on the hydrolytic activity of serum albumin towards esters and organophosphates. Previously, with the help of the technology of proton nuclear magnetic resonance (H NMR) spectroscopy, we observed the yield of acetate in the solution of bovine serum albumin and -nitrophenyl acetate (NPA). Thus, we showed that albumin possesses true esterase activity towards NPA.

The aim of the study was to analyze the effect of 2 h of inhalation of a krypton-oxygen mixture (Kr 70%/O 30%) on the recovery of neurological functions and the degree of brain damage in rats after photoinduced ischemic stroke (PIS) and to investigate the possible mechanisms responsible for this neuroprotection. Experiments were performed on male Wistar rats weighing 250-300 g (n = 32).

Neurological deficit was assessed within 14 days using the limb placement test. MRI and histological study of the brain with an assessment of the size of damage were performed on day 14 after ischemia.
