objective: the objective of this study is to develop and assess targeted pamam-peg nanocarrier with anti-tag72 nanobody for t-bid gene coding construct delivery into the human colonic adenocarcinoma cells. materials and methods: nanobody (nb) coding sequence was subcloned into psj expression vector for large-scale production and then nb was purified by ni++ affinity chromatography. sds-page an...

We report the delivery of a hydrophobic pesticide, thiamethoxam, by water-soluble nanosized cationic dendrimers that contain hydrophobic dendritic polyesters and peripheral amines, demonstrated by DLS, spectral analysis and ITC. The dendrimer-based nanocarrier can efficiently deliver the pesticide into the live cells and largely increase the cytotoxicity of the drug.

A cationic fluorescence nanoparticle efficiently enters plants with high transfection efficacy. Applying a mixture of G2/dsRNA to the model plant, Arabidopsis root, leads to significant reduction in the expression of important developmental genes and results in apparent phenotypes. This study reports a non-viral gene nanocarrier which triggers gene silencing in plants and leads to systemic phen...

Early changes in systemic vascular stiffness and endothelial function can contribute to altered cerebrovascular hemodynamics impaired cognitive function; additionally, these point potential targets for prevention treatment strategies people with mild impairment. Although the pathogenic mechanisms underlying are heterogeneous complex, one common feature is development of cerebral blood flow (CBF...

Advanced and metastatic cancer forms are extremely difficult to treat and require high doses of chemotherapeutics, inadvertently affecting also healthy cells. As a result, the observed survival rates are very low. For instance, gemcitabine (GEM), one of the most effective chemotherapeutic drugs used for the treatment of breast and pancreatic cancers, sees only a 20% efficacy in penetrating canc...

Supramolecular vesicles which can successfully encapsulate DOX and exhibit rapid drug release in a low-pH environment are constructed based on the host-guest interaction of water-soluble pillar[5]arene and a BODIPY derivative. They show remarkable combination of chemo- and photodynamic activities, suggesting a promising drug nanocarrier.
