Аннотация: An experimental dosage form of rubomycin is developed: the drug is incorporated in absorbable polymeric (polyhydroxybutyrate) matrix in the form of microparticles. Antitumor efficiency of this rubomycin dosage form was studied in laboratory mice with transplanted Ehrlich ascitic carcinoma. Rubomycin deposited in polymeric microparticles exhibited pronounced antitumor activity, inhibited the proliferative activity of Ehrlich ascitic carcinoma, and improved survival of mice with tumors. This dosage form of the drug can be used for local injections. В© Springer Science+Business Media, Inc. 2008.

Аннотация: Microspheres have been prepared from the resorbable linear polyester of ?-hydroxybutyric acid (polyhydroxybutyrate, PHB) by the solvent evaporation technique and investigated in vitro and in vivo. Biocompatibility of the microspheres has been proved in tests in the culture of mouse fibroblast cell line NIH 3T3 and in experiments on intramuscular implantation of the microspheres to Wistar rats for 3 months. Tissue response to the implantation of polymeric microspheres has been found to consist in a mild inflammatory reaction, pronounced macrophage infiltration that increases over time, involving mono- and poly-nuclear foreign body giant cells that resorb the polymeric matrix. No fibrous capsules were formed around polymeric microparticles; neither necrosis nor any other adverse morphological changes and tissue transformation in response to the implantation of the PHB microparticles were recorded. The results of the study suggest that polyhydroxybutyrate is a good candidate for fabricating prolonged-action drugs in the form of microparticles intended for intramuscular injection.

Аннотация: Procedure for microencapsulation providing stable formation of high quality microspheres was designed. Conditions for deposition of the anthracycline antibiotic daunorubicin to polymer matrix were developed and microsheres loaded with various quantities of the drug were prepared. The kinetics of the in vitro and in vivo release of daunorubicin from the microsheres was studied. The rate of the rubomycin release to the medium in vitro (balanced phosphate buffer at 37.8В°C) in a 300-hour experiment directly depended on the quantity of the incorporated drug and averaged 0.81 В· 10 -4 to 2.3 В· 10 -4 mcg/mlВ·h. The experiment on laboratory animals with intraperitoneal administration of the rubomycin microsperes showed that the drug remained in the blood and abdominal liquid for a long time (up to 10 days). Possible control of the quantity of the rubomycin encapsulation to the polymer matrix, no sharp efflux of the drug at the early stages of the observation and low rate of the drug release to the medium allowed to conclude that the use of the biodegradable polymer microsperes as carriers of the high toxic antibiotic providing its prolonged action was prospective.

Аннотация: Various chronic inflammatory and necrotic processes in the liver parenchyma are accompanied by pathological morphofunctional changes, which are associated with hepatocyte death and hyperplasia of the connective tissue. Regeneration of the liver parenchyma should include not only prevention of fibrosis, but also stimulation of hepatocyte prolifearation. The adrenoceptor agonist dobutamine stimulated proliferative activity of cultured hepatocytes and prevented the development of postintoxication liver cirrhosis in mice produced by chronic poisoning with CCl4.

Аннотация: Hepatocyte proliferation in the liver regenerating after partial hepatectomy ceases when the organ is restored, and the mechanism of this phenomenon is still unclear. In the experiments on fusing hepatocytes from the reoenerated mouse liver (15 days after partial hepatectomy) with NIH 3T3 mouse fibroblasts, we revealed no DNA synthesis in the nuclei of stimulated fibroblasts in heterokaryons (in the presence of hepatocyte nuclei), whereas DNA synthesis in nonfused cells was undisturbed. In this work, our purpose was to find out whether the suppression of DNA synthesis in heterokaryons could be due to the appearance in hepatocytes of some endogenous factors having an inhibitory effect on proliferation. To this end, hepatocytes from the mouse liver regenerated after partial hepatectomy were treated with cycloheximide for 1-4 h and were then fused with stimulated fibroblasts. Such a short-term treatment of hepatocytes with cycloheximide proved to result in the loss of their ability to inhibit DNA synthesis in the nuclei of stimulated or quiescent fibroblasts in heterokaryons, but hepatocytes proper actively proliferated in the medium with a low serum content (0.2%). When the mice with the liver reoenerated after partial hepatectomy were treated with a single sublethal dose of cycloheximide (3 mg/kg), their hepatocytes taken two days after this treatment had no inhibitory effect. Puromycin, another inhibitor of protein synthesis, had the same effect on hepatocytes. These results may be interpreted as evidence that the final stage of liver regeneration after damage is controlled by the factors having a C C negative effect on cell proliferation.

Аннотация: Poly-3-hydroxybutyrate (PHB) films were plasma-treated using pure NH3, pure Ar or mixtures of the two different proportions (20%, 30%, 40%, 50%, 70% NH3 in Ar). Surface chemistry and surface topography changes of PHB films were observed after plasma processing in all plasma regimes. The XPS results confirmed the absence of chemical modification in the case of pure Ar plasma treatment. Nitrogen-containing groups (e.g., N–C[dbnd]O) were detected on the surfaces of P3HB films treated with NH3-containing plasma. The surfaces of the untreated P3HB films were hydrophobic, and plasma treatment turned the surfaces hydrophilic, irrespective of the treatment. A significant decrease in the contact angle and an increase in the free surface energy were observed. An insignificant surface ageing effect was observed when P3HB samples were exposed to air for 10 days. In NIH 3T3 mice fibroblast cells, cell adhesion was significantly improved after plasma treatment in an Ar atmosphere, which is likely related to the fact that there was a surface ? potential of 88.6 mV at neutral pH, causing a cleavage of the polymer chains and an increase in surface roughness. © 2018 Elsevier Ltd

Аннотация: The distribution in mice of intravenously injected modified nanodiamonds (MNDs) obtained by detonation synthesis was studied using electron paramagnetic resonance (EPR) spectrometry. It has been shown that 2.5 h after MND injection into the tail vein of mice, the nanoparticles accumulate mainly in the lungs and liver of animals; much smaller amounts of nanoparticles were found in the kidneys and heart. The presence of MNDs in the samples of blood, spleen, brain, and thigh muscles of mice was not detected within the sensitivity of the method used.

Аннотация: In vitro experiments proved the usefulness of electron paramagnetic resonance (EPR) spectrometry for detecting detonation nanodiamonds (NDs) in samples of biomaterials (blood and homogenates of organs of mice). A characteristic EPR signal (g = 2.003, Delta H similar or equal to 10 G) was detected in biomaterials containing NDs, and its intensity linearly increased at nanoparticle concentrations of between 1.6 and 200 mu g/ml. In vivo experiments demonstrated that EPR spectrometry was effective for monitoring the inter-organ distribution of NDs intravenously injected to mice. In 2.5 h after the injection of NDs, the nanoparticles mainly accumulated in the lungs and liver of the animals - about 25 and 20%, respectively, of the initially injected NDs. The amounts of NDs accumulated in the heart and kidneys were considerably lower. Also, EPR spectrometry did not detect NDs in the blood, spleen, brain, and femoral muscles of mice. Ten days after injection, EPR spectrometry detected redistribution of NDs in mice. The amounts of nanoparticles decreased approximately by a factor of 3.5 in the lungs and increased almost by a factor of 3 in the liver; NDs were detected in the spleen. This study suggests ways to use EPR spectrometry to study the distribution, accumulation, and elimination of detonation NDs injected into laboratory animals.

Аннотация: Background: Canine parvovirus (CPV) is now recognized as a serious threat to the dog breeding industry worldwide. Currently used CPV vaccines all have their specific drawbacks, prompting a search for alternative safe and effective vaccination strategies such as subunit vaccine. VP2 protein is the major antigen targeted for developing CPV subunit vaccine, however, its production in baculovirus expression system remains challenging due to the insufficient yield. Therefore, our study aims to increase the VP2 protein production by using an improved baculovirus expression system and to evaluate the immunogenicity of the purified VP2 protein in mice. Results: The results showed that high-level expression of the full length VP2 protein was achieved using our modified baculovirus expression system. The recombinant virus carrying two copies of VP2 gene showed the highest expression level, with a productivity of 186 mg/L, which is about 1.4-1.6 fold that of the recombinant viruses carrying only one copy. The purified protein reacted with Mouse anti-His tag monoclonal antibody and Rabbit anti-VP2 polyclonal antibody. BALB/c mice were intramuscularly immunized with purified VP2 protein twice at 2 week intervals. After vaccination, VP2 protein could induce the mice produce high level of hemagglutination inhibition antibodies. Conclusions: Full length CPV VP2 protein was expressed at high level and purified efficiently. Moreover, it stimulated mice to produce high level of antibodies with hemmaglutination inhibition properties. The VP2 protein expressed in this study could be used as a putative economic and efficient subunit vaccine against CPV infection. © 2020 The Author(s).

Аннотация: Considerable efforts have been focused on shifting the wavelength of aequorin Ca2+? dependent blue bioluminescence through fusion with fluorescent proteins. This approach has notably yielded the widely used GFP?aequorin (GA) Ca2+ sensor emitting green light, and tdTomato-aequorin (Redquorin), whose bioluminescence is completely shifted to red, but whose Ca2+ sensitivity is low. In the present study, the screening of aequorin mutants generated at twenty?four amino acid positions in and around EF?hand Ca2+?binding domains resulted in the isolation of six aequorin single or double mutants (AequorinXS) in EF2, EF3, and C?terminal tail, which exhibited markedly higher Ca2+ sensitivity than wild?type aequorin in vitro. The corresponding Redquorin mutants all showed higher Ca2+ sensitivity than wild?type Redquorin, and four of them (RedquorinXS) matched the Ca2+ sensitivity of GA in vitro. RedquorinXS mutants exhibited unaltered thermostability and peak emission wavelengths. Upon stable expression in mammalian cell line, all RedquorinXS mutants reported the activation of the P2Y2 receptor by ATP with higher sensitivity and assay robustness than wt?Redquorin, and one, RedquorinXS?Q159T, outperformed GA. Finally, wide?field bioluminescence imaging in mouse neocortical slices showed that RedquorinXS?Q159T and GA similarly reported neuronal network activities elicited by the removal of extracellular Mg2+. Our results indicate that RedquorinXS?Q159T is a red light?emitting Ca2+ sensor suitable for the monitoring of intracellular signaling in a variety of applications in cells and tissues, and is a promising candidate for the transcranial monitoring of brain activities in living mice. © 2020 by the authors.
