physicochemical properties of polymers

Aerosol gene formulations are divided according to the current delivery systems for the lung: nebulizers, dry powder inhalers and pressurized metered dose inhalers; highlighting its benefits, challenges and potential application. The problem of how much detail is appropriate has become a pressing issue because of the continuous and rapid increase in the amount of information in biomedical sciences. 6,7 We sought to address both of these problems via the development of bio-degradable analogues of PEI incorporating reducible disulfide bonds within linear poly(alkylenimine) backbones. Indeed, h, Our studies also showed that the mixture of a plasmid DNA, DNA alone in mice model. However, this effect is modest, and could still exclude larger delivery devices, as many devices are on the order of 50-200 nm in diameter, ... PEG has been used to coat PLA nanoparticles, and it usually aggrandizes the solubility of nanoparticles, decreasing their aggregation and interaction with proteins in physiological fluids. 123. Moreover, the transfection in different cell lines showed that TSPG complex could induce higher gene expression in asialoglycoprotein receptor-riched HepG2 cells than HeLa cells, which lacks such receptor. Also, variety kinds of application of collagen DDS for gene therapy using adenovirus vector, antisense DNA and DNA vaccine, will be discussed. Ferreira, S. A.; Gama, F. M.; Vilanova, Aghasadeghi, M. R.; Sadat, S. M. Hum Vaccin Immunother, 141. denses the plasmid to protect it against DNase degradation. Im Rahmen dieser Arbeit wurden neuartige sternförmige Nanopartikel vorgestellt, die sich zur Transfektion von Säugerzellen eignen. Der Grund liegt vermutlich in der geringeren elektrostatischen und sterischen Abstoßung der Nanosterne.

But, the particles with size of 50 nm are, interstitial flow and transported to regional draining lymph, nodes, where concentrated populations of resident immature, DCs internalize them. The density of Poly Methyl Pentane is 830 kg per cubic meter, Polypropylene (PP) is 905 kg per cubic meter, and Polytetrafluoroethylene (PTFE) is 2150 kg per cubic meter. By decreasing the ambient pH, the. The reports indicated, Succinated chitosan (CHI-succ) increased water sol-, Insufficient interaction between the poly-, The researchers showed that hyaluronic acid-chito-, 600 Da) was immunologically more efficient than E7. poly(ethylene glycol)-grafted chitosan (FA–PEG-CS) c, increase solubility, transfection efficiency, mers and cells is one of the important problems of polylactide. Auch die Größe der Polyplexe zeigte eine Abhängigkeit vom N/P-Verhältnis, wobei eine Erhöhung von letzterem bis zu einer Sättigungsgrenze zu einer Verkleinerung der hydrodynamischen Radien führte. Modification of polymers by adding diamine monomers also, that the degree of deacetylation (DDA), molecular weight and, charge of chitosan, and the pH of media are important to, identify the transfection efficiency of p, complex). Deshpande, M. C.; Davies, M. C.; Garnett, M. C.; Williams, P. Stolnik, S. J Controlled Release 2004, 97, 143–156. Nicoletta Rescignano, Jose Maria Kenny, in Core-Shell Nanostructures for Drug Delivery and Theranostics, 2018. Using fluorescence microscopy to simultaneously trace both the plasmid and polymer during gene delivery in combination with an in vitro transcription assay, we provide evidence that plasmid unpackaging can indeed be a limiting step for gene expression for sufficiently large polymer constructs. © 2019 Wiley Periodicals, Inc. J Biomed Mater Res B Part B, 2019. Der Grund liegt vermutlich in der geringeren elektrostatischen und sterischen Abstoßung der Nanosterne. removed by using peptides. Furthermore, cascading multiscale drug delivery devices could address these issues by sequentially presenting targeting ligands for crossing each of the aforementioned hurdles. ... Dabei 41 zeigte sich, dass die Polyplexe, die nach dem adaptierten Protokoll gebildet wurden, im untersuchten Bereich von N/P = 3 bis 10 durchweg deutlich kleiner waren (Abbildung 13).Ab N/P ≥ 10 sanken die hydrodynamischen Radien auf Werte vergleichbar zum adaptierten Protokoll von < 300 nm. 2. Even slight changes can exclude polymers from applications. Physicochemical properties of nanomaterials recommended by ISO/TR 13014 (ISO, 2012a) and ISO/TR 13329 (ISO, 2012b), H. Niemann, ... J.W. Therefore, delivery systems of such drugs are important research subjects in the field of pharmacology, and to prolong the effect of these drugs, many studies are being conducted to control the release of proteins and polynucleotides from various carrier materials. In this article, we report on the controlled release of protein drugs using collagen, focusing on a new drug delivery system (DDS), the Minipellet, as our basic technology. A single injection of collagen DDS containing plasmid DNA produced physiologically significant levels of gene-encoding proteins in the local site and systemic circulation of animals and resulted in prolonged biological effects. For example, some lip, induce partial changes of B to A and B to C conformational, interact with negatively charged proteoglycans of the cell mem-, branes followed by endocytosis. The, use of elements modulating these pathways improv, Chlorpromazine (an inhibitor of the clathrin pathway), could partially inhibit the internalization of PEI carry, splice-shifting oligonucleotide, in contrast with methyl-, cyclodextrin (CD; an inhibitor of lipid rafts or caveolae) which, could prevent the internalization almost completely, be mentioned that most polyplexes are taken up by lipid raft-, mediated endocytosis. The physicochemical properties of the upgraded bio-oil are shown in Table 13.2 for the example of a bio-oil obtained from pine sawdust and treated at 500 ºC with a heating ramp of 12 ºC/min, where they can be compared with those of the parent bio-oil. Finally, we describe a thermodynamic model that supports these data by showing that shorter polycations can have a higher probability of dissociating from DNA. Namvar A (1), Bolhassani A, Khairkhah N, Motevalli F. Author information: (1)Department of Hepatitis and AIDS, Pasteur Institute of Iran, Tehran, Iran. Thermoplastic starch (TPS) films are considered one of the most promising alternatives for replacing synthetic polymers in the packaging field due to the starch biodegradability, low cost, and abundant availability. These strategies will enable rational design of cascading multiscale nano-delivery devices to combat neurodegeneration. . For all these reasons, we have realized the value for many medical students of presenting the principles of immunology in a concise and clear manner. B-form of the cellular DNA structure is also important issue, especially after binding. However its progress from the laboratory to the. Debska, G.; Szewczyk, A. Mol Ther 2005, 11, 990–995. In a comparative fashion, the impact of PEGylation strategies and monodisperse PEG sizes on the physicochemical and biological properties, including lipophilicity, thermosensitivity, biocompatibility, plasma stability, and drug delivery capability, of peptidic polymers has been quantitatively studied. The size of linear, DNA influences its passive diffusion (200–310 bp), active, transport (310–1500 bp) or NLS-mediated deli, gation of a 900 bp expression cassette to, approach to increase the efficiency of foreign DNA nucle, ery efficiency to the targeted tissues. In addition, these polymers also serve as adjuvants to enhance the immunogenicity of vaccine. Dufes, C.; Uchegbu, I. F.; Schatzlein, A. G. Adv Drug Deliv Rev. The recent progress has shown that stimuli-responsive polymers entitled as multi-functional nucleic acid vehicles can act to target specific cells. pH represents the alkalinity or acidity of biochar. host genome. The endosomal buffering and solubility was improved by. It was also observed that the content of water was increased as a consequence of the selective loss of volatile products during the thermal treatment. As teachers of immunology, we are becoming increasingly aware that assimilating detailed information as well as experimental approaches is difficult in many medical school and undergraduate courses. © 2008-2020 ResearchGate GmbH. Particle size and zeta potential were related to the weight ratio of CP:DNA, where decreases in nanoparticle size and increases in surface charge were observed as CP content increased. These poly-, mers can act as synthetic adjuvants, which can also be, conjugated with immunostimulants. Win, K. Y.; Feng, S. S. Biomaterials 2005, 26, 2713–2722. Auffällig war dabei der hohe Anteil magnetischer Zellen bei der Transfektion mit Nanosternen mit einer geringen Armdichte. tion of cholesterol to low molecular weight PEI (1800 Da). Thus, understanding the physicochemical properties of slurry is important to develop CMP slurries. Darüber hinaus wurde demonstriert, wie die Elektronenenergieverlustspektroskopie (EELS) die Unterscheidung von Nanopartikeln und kontrastiertem biologischem Material ermöglicht. Their successful clinical, delivery and development of carriers overcoming these bar-, ciency in lower MW hinders their application; thus the, modification of physicochemical properties as an important, approach can be considered to enhance the potency of gene. The value of CEC for a biochar is closely dependent on its exchangeable cations such as H+, K+, Na+, and Ca2+. Most commonly, modifications are done with polymers, and the most used polymer is PEG. Bertesteanu, S.; Chifiriuc, M. C.; Grumezescu, A. M.; Printza. In this review, we provide an overview of technologies developed to cross the blood-brain barrier, to be internalized by diseased neuronal membranes, and to navigate to the organelle of interest, and summarize strategies for integration of these concepts. Melisa Bertero, Ulises Sedran, in Recent Advances in Thermo-Chemical Conversion of Biomass, 2015. density which depolarizes the mitochondrial membranes. Physical Properties: Structure, Chain Length, and, Cationic polymers contain natural DNA-binding proteins, (e.g., histones), synthetic polypeptides, poly(ethylenimine), (PEI), cationic dendrimers, 2-dimethyl (aminoethyl) methac-, tosan). An amorphous, hydrophilic polymer is recommended for rapid release, up to 1 month, whereas a highly crystalline polymer is considered best for slow release, lasting more than 6 months. For an efficient gene transfection, vecto, should be unpackaged to release the loaded nucleic acids fol-, weight of polymers significantly control the efficie, other hand, PEI grafted with chitosan (CH-, the transfection efficiency through poten, HepG2, HeLa, and primary hepatocytes cells. Hoffman, A. S. Adv Drug Delivery Rev 2013, 65, 10–16. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Nucleic acid-based drugs offer a potentially effective tool for treatment of a variety of diseases, including cancer, cardiovascular diseases, neurological disorders, and infectious diseases. Putnam, D.; Zelikin, A. N.; Izumrudov. These properties make PAMAM dendrimers the carriers that are obliged to carry out future polycation-based gene delivery studies. These non-viral carriers are classified by the type of stimulus including reduction potential, pH, and temperature. This helps in tracking cellular processes effectively and for long periods of time [31]. 32. Physicochemical properties of QDs are as follows: QDs are more photostable as compared to traditional dyes. The drug release can be modified, that is extended and controlled, from hours to months with the selection of proper molecular weight and the nature of the polymer. A higher CEC of biochar will aid the retention of nutrients (e.g., N, P, and K) as well as the adsorption of contaminants when applied to soil. Es wurden keine freien Nanopartikel im Zytoplasma oder im Zellkern gefunden. By continuing you agree to the use of cookies. Considerably, large hydrodynamic, size of plasmid DNA (pDNA) does not readily penetrate into, the cellular membranes, thus, it should be complexed with cat-, Each polymer has a unique molecular weight, which a minor modification can affect its, Recent improvements in the controlled radi-, cal polymerization (CRP) has authorized f, synthesis of well-defined macromolecules with accurate control, on molecular weights providing a low polydispersity index, branched polymers is more readily accessible than other, approaches. Gels Horizons: From Science to Smart Materials. To generate lactose-free milk, a knockout or knockdown of the α-lactalbumin locus would suppress this key step in milk sugar synthesis. Lonez, C.; Vandenbranden, M.; Ruysschaert, J. M. Prog Lipid, 7. great interest for using nonviral vectors composed of lipids, nanoparticle-based compounds. The molecules could self-assemble to form micelles and exhibit aggregation-induced emission (AIE) property which may be used for cell imaging. Ionophores or lysosomotropic amines, such as methylamine, that raise intralysosomal pH provided substantial protection of the cells from killing by lysosomotropic detergents. In this chapter, we give a brief overview of the preparation and characterization of CMP slurry, and then mainly discuss the effect of slurry characterization on CMP performances. Für die Transfektionsstudien wurden Polyplexe aus verschiedenen Varianten der Nanostern-Bibliothek und einem Plasmid, welches für das grün fluoreszierende Protein (GFP) kodiert, gebildet und verschiedene Zelllinien transfiziert (CHO-K1, HEK-293, L929, Jurkat). Bei der nicht-viralen Transfektion werden synthetische Vektoren (z.B. Delivery experiments proved that the poly(galactosyl ureaethyl methacrylate -b-dimethylamino ethyl methacrylate) diblock copolymer (pGa4D47), internalized in a receptor-mediated manner, exhibited a much faster nuclear transportation than ODNs carried by pDMAEMA homopolymer or glycopolymer bearing glucose moieties. The aim of this project is to evaluate the sorting performances of near infrared (NIR) devices, developed by the company PELLENC ST, for three styrenic polymers from WEEE: acrylonitrile-butadiene-styrene (ABS), high-impact polystyrene (HIPS) and ABS/polycarbonate blend (ABS/PC) and to study the physico-chemical properties of recycled materials. The nonspecific adsorptive, endocytosis is an important step for both binding and subse-, quent internalization but unfortunately poses concerns for in, Cellular uptake is mediated by different types of endocytosis, such as endocytosis via clathrin, endocytosis via caveolae/lip-, ids-raft, and clathrin/caveolae-independent endocytosis. The objective of this study was to evaluate the changes within the physicochemical properties of gelatine (2%; 4%; 8%), carrageenan (1.5%; 2%; 2.5%) and sodium alginate (0.75%; 1%; 1.25%) hydrogels with different sodium chloride concentrations that were triggered by applying direct current (DC) of 400 mA for a duration of five minutes. Cell killing by the lysosomotropic detergents exhibited strongly sigmoidal dose-response curves. Yu, ... K. Ahn, in Health and Environmental Safety of Nanomaterials, 2014. Combining the acceptor–donor–acceptor-type fused ring-based molecular architecture into a polymeric backbone is a promising strategy to design polymer acceptors for high-performance all-polymer solar cells (all-PSCs), and use of single isomer monomers is critical to control their physicochemical and photovoltaic properties. mechanisms including high DNA protection, and improved, tion efficiency toward the cell cycle status varies among, ciency of linear PEI-containing polyplexes and electropora-, tion is insensitive to the cell cycle, whereas the transfection, lipofectamine-containing lipoplexes depends on the cell, While naked DNA (linear or plasmid) can traverse, the nuclear pores of intact nuclei, the process is inefficient, as compared with that of viral genomes. For all these reasons, we have realized the value for many medical students of presenting the principles of immunology in a concise and clear manner. For instance, Histone H3 tail peptide-conjugated, through the Golgi and ER before nuclear entr, (dextran)-Prot (protamine)-DNA-SLN (solid lipid nanopar-, ticles) vector exhibited a higher transfection in the cells due to, clathrin/caveolae-mediated endocytosis. The average cell viability after the treatment with CP/DNA nanoparticles was over 90% in both chondrocytes and synoviocytes, which was much higher than that of PEI (25 kDa)/DNA nanoparticles. On the other hand, transgenic mice with a homozygous knockout for α-lactalbumin could not nurse their offspring because of the high viscosity of their milk. Lactose-reduced or lactose-free milk would render dairy products suitable for consumption by the large proportion of the world’s adult population who do not produce active intestinal lactase [13]. This is due to their inorganic composition and the fluorescence intensity they work on [29]. Generally, the physicochemical characterization of DNA-polymer complexes is critical to enhance the transfection potency via protection of DNA from nuclease digestion, endosomal escape, and nuclear localization. The aim of this study is the analyze the structure of branched polyurethanes based on synthetic poly([R,S]-3-hydroxybutyrate) and their blends with biopolymers and montmorillonite. Inhaled gene delivery: a formulation and delivery approach. The problem of how much detail is appropriate has become a pressing issue because of the continuous and rapid increase in the amount of information in biomedical sciences. 103. This problem is compounded by the development of integrated curricula in many medical schools, with reduced time for didactic teaching and an increasing emphasis on social and behavioural sciences and primary health. HPV16 L1 production in a novel expression system.
