Nanoceria (cerium dioxide nanoparticles, CeO2) has a broad range of biological properties including antiviral activity. The hypothesis was that nanoceria can efficacy against coronavirus (coronavirus porcine transmissible gastroenteritis) and potentially target SARS-CoV-2. Transmissible gastroenteritis (TGEV) is the etiologic agent (PTG), highly contagious pig intestinal disease. aim study to d...
Physical virology seeks to define the principles of physics underlying viral infections, traditionally focusing on the fundamental processes governing virus assembly, maturation, and disassembly. A detailed understanding of virus structure and assembly has facilitated the development and analysis of virus-based materials for medical applications. In this Physical Virology review article, we dis...
context: over the last few decades, extensive efforts have been made worldwide to develop nanomedicine delivery systems, especially via oral route for antidiabetic drugs. absorption of insulin is hindered by epithelial cells of gastrointestinal tract, acidic gastric ph and digestive enzymes. evidence acquisition: recent reports have identified and explained the beneficial role of several struct...
in the present work, the synthesis of barium hexaferrite (bafe12o19) nanoparticles in thepresence of a large excess amount of oh− anions by the hydrothermal method in the presence and absence of surfactants such as sodium dodecyl benzene sulfonate and triton x-114 was reported. the optimized temperature in the absence of surfactant was determined (200 °c) and then barium hexaferrite nanoparticl...
nanoparticles of the zno and tio2 were synthesized and the physicochemical properties of the compounds were characterized by ir, x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission electron microscopy (tem). the xrd patterns of the zno and tio2 nanoparticles could be indexed to hexagonal and rutile phase, respectively. aggregated nanoparticles of zno and tio2 with spher...
Cowpea mosaic virus (CPMV) is a plant virus which is being extensively investigated as a drug delivery and vaccine nanocarrier for parenteral administration. However, to date little is known about the suitability of plant-based nanocarriers for oral delivery. In this study, the colloidal (i.e. aggregation), physical (i.e. denaturation) and chemical (i.e. digestion of the polypeptides) stability...
background cucumber mosaic virus (cmv) has isometric particles with a diameter of about 28–29 nm. a useful method to recognize regions from mutagenesis in the coat protein (cp) gene are important for particle assembly and the expression of viral in cp expression systems like bacteria such as e.coli or yeast as well as their assembly into virus-like particles (vlp). objectives in this paper, we ...
Magnetic nanoparticles attracted a great deal of attention in the medical applications due to their unique properties. The most exceptional property of magnetic particles is their response to a magnetic force, and this property has been utilized in applications such as drug targeting, bioseparation, contrast agents in magnetic resonance imaging (MRI) and heating mediators for cancer therapy. In...
Among many thermo-photochromic materials, the color-changing behavior caused by temperature and light is usually lack of a full color response. And the study on visible light-stimuli chromic response is rarely reported. Here, we proposed a strategy to design a thermo-photochromic chameleon biomimetic material consisting of photonic poly(N-isopropylacrylamide-co-methacrylic acid) copolymer and p...
چکیده در سال 2000 ویروسی از سرم نمونه های خونی با استفاده از پرایمرهای t935و t814 در ژاپن جداسازی شد و تحت عنوان ttv like mini virus (tlmv) نامگذاری شد. اخیراً کمیته بین المللی طبقه بندی ویروس ها (ictv) نام آن را بهtorque teno mini virus (ttmv) تغییر داده است. این ویروس در جنس betatorquevirus از خانواده anelloviridae جای گرفته است. اطلاعات کمی در مورد شیوع ttmv در انسانها وجود دارد. گزارارشات ا...
