Both folic acid (FA)- and methoxypoly(ethylene glycol) (mPEG)-conjugated chitosan nanoparticles (NPs) had been designed for targeted and prolong anticancer drug delivery system. The chitosan NPs were prepared with combination of ionic gelation and chemical cross-linking method, followed by conjugation with both FA and mPEG, respectively. FA-mPEG-NPs were compared with either NPs or mPEG-/FA-NPs...

background and aims: although metal and metal oxide nanoparticles are used in different medical applications, they may have considerable toxicity on various cells, such as myocytes. therefore, this study aimed to evaluate the toxicity of the naked and serum-treated silver nanoparticles (ag nps) and magnesium oxide nanoparticles (mgo nps) on the cardiomyocytes. materials and methods: cardiomyocy...

1. In order to complete the demonstration that the viscosity of suspensions of powdered gelatin in water is influenced by electrolytes in a similar way as the viscosity of solutions of gelatin, it is necessary to prove that the characteristic valency effect exists also in the case of the viscosity of suspended particles of solid gelatin in water. This proof is furnished in Fig. 1. 0.5 gm. of fi...

The usage of gelatin hydrogel is limited due to its instability and poor mechanical properties, especially under physiological conditions. Divalent metal ions present in gelatin such as Ca(2+) and Fe(2+) play important roles in the gelatin molecule interactions. The objective of this study was to determine the impact of divalent ion removal on the stability and mechanical properties of gelatin ...

1. Cooper's gelatin purified according to Northrop and Kunitz exhibited a minimum of osmotic pressure and a maximum of opacity at pH 5.05 +/-0.05. The pH of solutions of this gelatin in water was also close to this value. It is inferred that such gelatin is isoelectric at this pH and not at pH 4.70. 2. Hydrogen electrode measurements with KCl-agar junctions were made with concentrated solutions...

UNLABELLED Alaska pollock (Theragra chalcogramma) is the U.S.A.'s largest commercial fishery, with an annual catch of over 1 million tons. During pollock processing, the skins are discarded or made into fish meal, despite their value for gelatin production. The absence of gelatin-processing facilities in Alaska necessitates drying of the skins before transport to decrease the moisture content, ...

Gelatin isolated from limed split wastes can be a high value product due to its special characteristics and has many potential future applications in Food, functional additives, Food and pharmaceutical industries. Concentrations of sodium hydroxide, sulfuric and acetic acids used in processing gelatin from Narrow barred, Carcharhinus Leucas, Siganus Sutor and Indo Pacific king mackerel skins af...

BACKGROUND Earlier studies have shown that adrenomedullin (AM), a potent vasodilator peptide, has a variety of cardiovascular effects. However, whether AM has angiogenic potential remains unknown. This study investigated whether AM gene transfer induces therapeutic angiogenesis in chronic hind limb ischemia. METHODS AND RESULTS Ischemia was induced in the hind limb of 21 Japanese White rabbit...

Gelatin is a natural biocompatible, nontoxic, edible and an inexpensive molecule. These properties result in its wide applications and recently it has been used for the delivery of the gene therapeutic entities such as plasmid DNA and paclitaxel drug based delivery for the various types of Cancer cells including Bladder cancer cells and prostate cancer cells. Generally, gelatin nanoparticles ca...

in addition to its antioxidant effect, vitamin e or α–tocopherol is suggested to enhance remyelination in the animal model of non-inflammatory demyelination. in this study, the possible proliferative effect of vitamin e on human- induced pluripotent stem cell-derived neural progenitors (hips-nps) and the underlying mechanisms were investigated in vitro. nps were induced from ips cells via 3 ste...
