Multicompartment colloid systems with lipid and polymer membranes for biomedical applications.

Multicompartment structures have the potential for biomedical applications because they can act as multifunctional systems and provide simultaneous delivery of drugs and diagnostics agents of different types. Moreover, some of them mimic biological cells to some extent with organelles as separate sub-compartments. This article analyses multicompartment colloidal structures with smaller sub-units covered with lipid or polymer membranes that provide additional protection for the encapsulated substances.

Prediction and Construction of Energetic Materials Based on Machine Learning Methods.

Energetic materials (EMs) are the core materials of weapons and equipment. Achieving precise molecular design and efficient green synthesis of EMs has long been one of the primary concerns of researchers around the world. Traditionally, advanced materials were discovered through a trial-and-error processes, which required long research and development (R&D) cycles and high costs.

Molecular genetic detection and differentiation of Xanthomonas oryzae pv. oryzicola, bacterial leaf streak agents of rice.

The genus Xanthomonas comprises phytopathogenic bacteria which infect about 400 host species, including a wide variety of economically important plants. Xanthomonas oryzae pv. oryzicola (Fang et al.

Sodium Accumulation in Infected Cells and Ion Transporters Mistargeting in Nodules of : Two Ugly Items That Hinder Coping with Salt Stress Effects.

The maintenance of intracellular nitrogen-fixing bacteria causes changes in proteins' location and in gene expression that may be detrimental to the host cell fitness. We hypothesized that the nodule's high vulnerability toward salt stress might be due to alterations in mechanisms involved in the exclusion of Na from the host cytoplasm. Confocal and electron microscopy immunolocalization analyses of Na/K exchangers in the root nodule showed the plasma membrane (MtNHX7) and endosome/tonoplast (MtNHX6) signal in non-infected cells; however, in mature infected cells the proteins were depleted from their target membranes and expelled to vacuoles.

Structure and Magnetic Properties of a Nanosized Iron-Doped Bismuth Titanate Pyrochlore.

The nanosized (50-70 nm) pyrochlore BiFeTiO was prepared by a coprecipitation technique. Characterization of BiFeTiO was carried out by powder X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), Raman spectroscopy, Mössbauer spectroscopy, and magnetic susceptibility measurements. The study of Fe doping in BiTiO was performed by means of density functional theory (DFT) calculations.
