In this study, using human tongue squamous carcinoma cells (HSC-4) carcinostatic activity was compared for diverse L-ascorbic acid (Asc) derivatives, including the 'straight-C(16)-chain types', 6-O-palmitoyl-Asc (A6-P) and Asc-2-phosphate-6-O-palmitate sodium salt (APPS), as well as the
Combined antitumour effects of mono- or diacyl ascorbates and heat treatment were studied in comparison with the parent compound, L-ascorbic acid (AsA). At 37 degrees C, 75 microM 6-O-palmitoyl (6P) and 6-O-stearoyl (6S) ascorbates appreciably inhibited DNA synthesis in Ehrlich ascites tumour cells.
We have studied interaction of well known antioxidant L-ascorbic acid with magnetic nanoparticles containing insoluble Fe(III) in their core. In analogy with ferritin, mobilization of iron in the form of water soluble Fe(II) was observed, especially pronounced at higher temperatures. In the presence
In the present study, we investigated the induction of the p38-MAPK signalling pathway by copper, as exemplified by CuCl(2), in the isolated perfused heart of the amphibian Rana ridibunda. We found that p38-MAPK phosphorylation by CuCl(2) occurs in a dose-dependent manner, with maximum activation
The roots of Rhododendron mucronulatum Turzaninov have been used in Oriental traditional medicine for the treatment of dysuria, fever, increase of digestive activity and tonics in China and Korea. Activity guided isolation of the roots of Rhododendron mucronulatum Turzaninov has led to the isolation
Sulphonamide idiosyncratic toxicosis has been reported in 28 dogs. Non-septic polyarthritis and fever occurring after 8 to 21 days therapy was the most common manifestation. Of 22 dogs with this syndrome, 7 were Doberman Pinschers. In humans, inherited decreased ability to detoxify sulphonamide
The aim of the present study is to determine the anti-proliferative activity of 6-o-palmitoyl-L: -ascorbic acid (Asc6Palm) that is a lipophilic derivative of L: -ascorbic acid (Asc), on human tongue squamous carcinoma HSC-4 cells by combined use of hyperthermia in comparison to Asc. Asc6Palm or Asc
Due to the interesting magnetic and electrical properties with good chemical and thermal stabilities, nickel ferrite nanoparticles are being utilized in many applications including magnetic resonance imaging, drug delivery and hyperthermia. Recent studies have shown that nickel ferrite nanoparticles
OBJECTIVE
The aim of this study was to evaluate inhibitory effects of L-ascorbic acid-2-O-phosphate-Na(2) (APS), a pro-vitamin C, combined with hyperthermia on adipogenic differentiation of mouse stromal cells, OP9.
METHODS
OP9 preadipocytes were differentiated with serum replacement, administered
