Gelatin Nanoparticles

PEGylated gelatin nanoparticles loaded with colchicine were prepared by ethanol precipitation method. Poly-(ethylene glycol)-5000-monomethylether (MPEG 5000), a hydrophilic polymer, was used to pegylate gelatin.  Gluteraldehyde was used as cross-linking agent. To obtain a high quality product, major formulation parameters were optimized.  Spherical particles with mean particles of 193 nm were measured by a Malvern particle size analyzer. Entrapment efficiency was found to be 71.7 ± 1.4% and determined with reverse phase high performance liquid charomatography (RP-HPLC). The in vitro drug release study was performed by dialysis bag method for a period of 168 hours. Lyophilizaton study showed sucrose at lower concentrations proved the best cryoprotectant for this formulation.  Stability study revealed that lyophilized nanoparticles were equally effective (p < 0.05) after one year of storage at 2-8°C with ambient humidity. In vitro antitumoral activity was accessed using the MCF-7 cell line by MTT assay.  The IC50 value was found to be 0.034 μg/ml for the prepared formulation. The results indicate that PEGylated gelatin nanoparticles could be utilized as a potential drug delivery for targeted drug delivery of tumors.

Camellia Species

Medicinal plants have been used since antiquity to cure illnesses and injuries. In the last few decades, natural compounds extracted from plants have garnered the attention of scientists and the Camellia species are no exception. Several species and cultivars are widespread in Asia, namely in China, Japan, Vietnam and India, being also identified in western countries like Portugal. Tea and oil are the most valuable and appreciated Camellia subproducts extracted from Camellia sinensis and Camellia oleifera, respectively. The economic impact of these species has boosted the search for additional information about the Camellia genus. Many studies can be found in the literature reporting the health benefits of several Camellia species, namely C. sinensis, C. oleifera and Camellia japonica. These species have been highlighted as possessing antimicrobial (antibacterial, antifungal, antiviral) and antitumoral activity and as being a huge source of polyphenols such as the catechins. Particularly, epicatechin (EC), epigallocatechin (EGC), epicatechin-3-gallate (ECG), and specially epigallocatechin-3-gallate (EGCG), the major polyphenols of green tea. This paper presents a detailed review of Camellia species’ antioxidant properties and biological activity.

Abstract The cell lineage origin of IFN-producing killer dendritic cells (IKDCs), which exhibit prominent antitumoral activity, has been subject to debate. Although IKDCs were first described as a cell type exhibiting both plasmacytoid DC and natural killer (NK) cell properties, the current view reflects that IKDCs merely represent activated NK cells expressing B220, which were thus renamed B220+ NK cells. Herein, we further investigate the lineage relation of B220+ NK cells with regard to other NK-cell subsets. We surprisingly find that, after adoptive transfer, B220− NK cells did not acquire B220 expression, even in the presence of potent activating stimuli. These findings strongly argue against the concept that B220+ NK cells are activated NK cells. Moreover, we unequivocally show that B220+ NK cells are highly proliferative and differentiate into mature NK cells after in vivo adoptive transfer. Additional phenotypic, functional, and transcriptional characterizations further define B220+ NK cells as immediate precursors to mature NK cells. The characterization of these novel attributes to B220+ NK cells will guide the identification of their ortholog in humans, contributing to the design of potent cancer immunotherapies.
