Combining Adipose‐Derived Stromal Cell Spheroids and Melt Electrowritten Scaffolds for a 3D Adipose Model Mimicking Structure and Function of Fat Tissue

Advanced NanoBiomed Research, EarlyView.
A 3D adipose tissue model is fabricated by combining melt electrowritten scaffolds with multicellular adipose‐derived stromal cell spheroids. The resulting constructs are characterized by a coherent, tissue‐like matrix. The lipid droplet size is tunable by oleic acid supplementation, reaching native‐like diameters.

Studies on castor oil. II. Hydrogenation of castor oil

Journal of the American Oil Chemists' Society, 1957
Summary Products of low iodine value (<10.0) and hydroxyl value (35–40) can be readily obtained by hydrogenating castor oil at atmospheric pressure and at temperatures of the order of 220°, using 1.0% Raney nickel. Dehydration of ricinoleic acid and subsequent hydrogenation of the resulting double bond as also simple saturation of ricinoleic acid ...

Ceramer coatings from castor oil or epoxidized castor oil and tetraethoxysilane [PDF]

Journal of the American Oil Chemists' Society, 2006
AbstractNew inorganic‐organic hybrids were synthesized through the reaction of castor oil (CO) or epoxidized castor oil (ECO) with tetraethoxysilane (TEOS). The mass proportions of ECO/TEOS varied from 90∶10 to 60∶40, and films of the material were thermally cured. An IR spectroscopy analysis was performed, and macro‐ and microscopic properties such as

Palatable Castor Oil.

JAMA: The Journal of the American Medical Association, 1906
Chicago, March 15, 1906. To the Editor: —Under a trade-mark name, a pleasant and palatable preparation of castor oil is being distributed among physicians. A small vial containing a sample of a sweetened, tasteless, palatable and non-acrid (I am not aware that castor oil possesses acrid properties) castor oil is sent to the practitioner, and this, in

Studies on castor oil. I. Fatty acid composition of castor oil

Journal of the American Oil Chemists' Society, 1956
Methyl esters of castor oil were prepared by saponifying the oil with potassium hydroxide in methanol, splitting the potassium soapsin situ with an excess of hydrochloric acid, and esterifying at room temperature. The esters had hydroxyl values comparable with those of the parent oils.

Biosynthesis of Ricinoleate in Castor Oil

1999
Castor oil is 90% ricinoleate (12-hydroxyoleate) and has numerous industrial uses. Components of castor bean (Ricinus communis L.) pose serious problems to processors. Other researchers have cloned the gene for the oleoyl hydroxylase, but transgenic plants produce only about 20% hydroxy fatty acid.

Biochemical aspects of castor oil biosynthesis

Biochemical Society Transactions, 2000
Castor oil is 90% ricinoleate (12-hydroxy-oleate) and has numerous industrial uses. Components of castor bean (Ricinus communis L.) pose serious problems to processors. We are evaluating two complementary approaches to providing a safe source of castor oil.
