Hydrogel nanoparticle encapsulated plasmid as a suitable gene delivery system

To facilitate the delivery of genetic material, the use of appropriate carriers such as polymers is necessary. Nanoparticles comprising of chitosan-alginate polymers were formed through pregel preparation method. Chi/Alg nanoparticles had a mean Z-Average diameter of 161.8 nm and mean zeta 29.3 mV, respectively. The ability of plasmid-complex in preventing DNA migration showed Chi/Alg nanoparticles have great capacity to maintain plasmid. The efficiency of nanoparticles for transfection of pEGFP-N1 plasmid in the cultured HEK 293 cells was measured by flow cytometry. Cell viability assays indicated that nanoparticles had no toxic effect on HEK 293 cells after 4 or 24 h. Our suitable candidate for gene delivery would be alg/chi nanoparticles.Для облегчения доставки генетического материала необходимо использование подходящих носителей, таких как полимеры. Наночастицы, состоящие из хитозан-альгинатных полимеров, были получены методом подготовки прегеля. Chi/Alg наночастицы имели средний диаметр 161.8 нм (Z-Average) и средний zeta-потенциал 29.3 mV. Отсутствие миграции ДНК во время электрофореза комплексов плазмиды с наночастицами показало, что Chi/Alg наночастицы могут удерживать плазмидную ДНК внутри комплекса. Эффективность наночастиц для трансфекции плазмиды pEGFP-N1 в культивируемые клетки HEK 293 была измерена с помощью жидкостной цитометрии. Тесты на жизнеспособ-ность клеток показали, что наночастицы не имели токсичного эффекта на клетки HEK 293 через 4 ч или 24 ч. Наночастицы Alg/Chi являются подходящим кандидатом для доставки генов

Scelio flavibarbis

Scelio flavibarbis (MARSHALL 1874) M a t e r i a l: Khuzestan province: Ahwaz, 3♀♀, 13, October 2003. Comment: KHAJEHZADEH and GHAZAVI (2000) reported that this parasitoid infests 27 % of the egg capsules resulting in destruction of some 4-16 % of eggs of Locusta migratoria.Published as part of Ghahari, H., Havaskary, M., Tabari, M., Ostovan, H., Sakenin, H. & Satar, A., 2009, An annotated catalogue of Orthoptera (Insecta) and their natural enemies from Iranian rice fields and surrounding grasslands, pp. 639-672 in Linzer biologische Beiträge 41 (1) on pages 663-664, DOI: 10.5281/zenodo.527624

Parasarcophaga jakobsoni ROHDENDORF 1937

<i>Parasarcophaga jakobsoni</i> ROHDENDORF 1937 <p>M a t e r i a l: Mazandaran province: Joibar, 13, September 2002.</p> <p> In this paper a diverse fauna of several predators and parasitoids were collected as the natural enemies of Iranian grasshoppers. In addition to this paper, many natural enemies including, <i>Blaesoxipha</i> spp. (Dip.: Sarcophagidae), <i>Stenopogon</i> spp. (Dip.: Asilidae), <i>Mylabris</i> spp. (Col.: Meloidae), <i>Sphex</i> spp. (Hym.: Sphecidae), <i>Mantis</i> sp. (Mantodea), <i>Cataglyphis</i> spp. (Formicidae), <i>Scelio flavibarbis</i> (Hym.: Scelionidae), <i>Podapolipus grissi</i> and <i>Leptus</i> sp. (Acari) and <i>Agriope</i> spp. (Aranei) were recorded by KHAJEHZADEH (2004). Also, four parasitic mites including, <i>Leptus fathipeuri</i> HAITLINGER & SABOORI, <i>L. zhangi</i> SABOORI & ATAMEHR, <i>L.</i> <i>esmailii</i> SABOORI & OSTOVAN and <i>Keramotrombium talebii</i> were reported by KARIMI IRAVANLOU & SABOORI (2000) and KARIMI IRAVANLOU & KAMALI (2000) as the parasites of Acrididae. Therefore, the populations of Orthoptera in Iranian rice fields are pressured severely by diverse natural enemies and the grasshoppers generally are not the key pests of rice fields.</p>Published as part of <i>Ghahari, H., Havaskary, M., Tabari, M., Ostovan, H., Sakenin, H. & Satar, A., 2009, An annotated catalogue of Orthoptera (Insecta) and their natural enemies from Iranian rice fields and surrounding grasslands, pp. 639-672 in Linzer biologische Beiträge 41 (1)</i> on page 665, DOI: <a href="http://zenodo.org/record/5276249">10.5281/zenodo.5276249</a&gt
