Pharmacokinetics, quorum-sensing signal molecules and tryptophan-related metabolomics of the novel anti-virulence drug Fluorothiazinon in a Pseudomonas aeruginosa-induced pneumonia murine model.

Pseudomonas aeruginosa (PA) infection is commonly associated with hospital-acquired infections in patients with immune deficiency and/or severe lung diseases. Managing this bacterium is complex due to drug resistance and high adaptability. Fluorothiazinon (FT) is an anti-virulence drug developed to suppress the virulence of bacteria as opposed to bacterial death increasing host's immune response to infection and improving treatment to inhibit drug resistant bacteria.

Pharmacokinetic Properties of the Novel Synthetic Cannabinoid 5F-APINAC and Its Influence on Metabolites Associated with Neurotransmission in Rabbit Plasma.

The strong psychoactive effects of synthetic cannabinoids raise the need for the deeper studying of their neurometabolic effects. The pharmacokinetic properties of 5F-APINAC and its influence on metabolomics profiles associated with neurotransmission were investigated in rabbit plasma. Twelve rabbits divided into three groups received 1-mL 5F-APINAC at 0.

QUALITY OF ORTHOPEDIC REHABILITATION OF PATIENTS WITH POST-TRAUMATIC DEFECTS OF THE UPPER JAW BY CHARACTERISTICS OF BIOCENOSIS OF THE ORAL CAVITY.

Objective: The aim of the research was to study the dynamics of the microbiota's features of oral mucosal membrane during orthopedic rehabilitation of patients with removable dentures which has an obturating part with two-layer bases.

Patients And Methods: Materials and methods: To achieve this goal, our bacteriological examination of oral cavity mucosa was performed for 25 patients with partial adentia of the upper jaw and defect of hard palate and alveolar process.

Results: Results and conclusions: Of the conducted studies indicate significant shifts in the qualitative and quantitative composition of microbiocenosis in the oral cavity in patients with partial adenia of the upper jaw and a defect of hard palate and alveolar process due to representatives of moraksel, enterobacteria (representatives of the kinds Klebsiella and E.

Determination of the immunostimulatory drug-glucosoaminyl-muramyl-dipeptide-in human plasma using HPLC-MS/MS and its application to a pharmacokinetic study.

GMDP (glucosoaminyl-muramyl-dipeptide), a synthetic analog of the peptidoglycan fragment of the bacterial cell wall, is an active component of the immunomodulatory drug Licopid. But the pharmacokinetic parameters of GMDP in humans after oral administration have not been investigated yet. The present study aimed at developing and validating a sensitive LC-MS/MS method for the analysis of GMDP in human plasma.

Application of 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate derivatization for enhanced peptide mapping analysis of non-biological complex drug glatiramer acetate using liquid chromatography/electrospray ionization collision-induced dissociation high-resolution mass spectrometry.

Rationale: Glatiramer acetate (GA) (Copaxone®) is a non-biological complex drug (NBCD) comprising random-sequence polymer chains of four amino acids (MW ~ 5-9 kDa) with unknown structure. The characterization of NBCDs by reversed-phase liquid chromatography/mass spectrometry (RPLC/MS) peptide mapping is often impeded by insufficient separation and/or low sensitivity. To overcome this issue, pre-column derivatization of GA peptide digest was used to improve RPLC/MS detectability and to generate a comprehensive peptide profile.
