[Identification of meldonium in the urine of volunteers using high-performance liquid chromatography-tandem mass spectrometry after consumption of milk of cows treated with a preventive course of the veterinary drug Emidonol].

Emidonol is a Russian antioxidant drug, widely used in veterinary medicine both for prophylactic purposes and under pathological conditions associated with oxygen deficiency. The product of its biotransformation in animals is meldonium, which is a metabolic modulator and has been included on the Prohibited List by the World Anti-Doping Agency (WADA) since 2016. In the presented research, volunteers once consumed samples of milk from cows that had undergone a 15-day course of the veterinary drug Emidonol® 10%, obtained from one of the farms in the Moscow region.

Liposome-encapsulated aprotinin biodistribution in mice: Side-by-side comparison with free drug formulation.

Injuries of the respiratory system caused by viral infections (e.g., by influenza virus, respiratory syncytial virus, metapneumovirus, or coronavirus) can lead to long-term complications or even life-threatening conditions.

Albumin incorporation into recognising layer of HER2-specific magnetic nanoparticles as a tool for optimal targeting of the acidic tumor microenvironment.

Cancer is unquestionably a global healthcare challenge, spurring the exporation of novel treatment approaches. In recent years, nanomaterials have garnered significant interest with the greatest hopes for targeted nanoformulations due to their cell-specific delivery, improved therapeutic efficacy, and reduced systemic toxicity for the organism. The problem of successful clinical translation of nanoparticles may be related to the fact that most in vitro tests are performed at pH values of normal cells and tissues, ranging from 7.

Carbene-coated metal nanoparticles for in vivo applications.

N-Heterocyclic carbenes (NHC) are well-recognized ligands of choice for preparing robust transition metal species. However, their use for fabrication of biomedically relevant nanoparticles has been limited to the synthesis of non-targeted particles showing increased tolerance to different aqueous coagulants. In this work, the first example of carbene-coated metal nanoparticles suitable for in vivo applications is presented.

Internalization of transferrin-tagged encapsulins into mesenchymal stem cells.

Currently, various functionalized nanocarrier systems are extensively studied for targeted delivery of drugs, peptides, and nucleic acids. Joining the approaches of genetic and chemical engineering may produce novel carriers for precise targeting different cellular proteins, which is important for both therapy and diagnosis of various pathologies. Here we present the novel nanocontainers based on vectorized genetically encoded (Mx) encapsulin, confining a fluorescent photoactivatable mCherry (PAmCherry) protein.
