Polymethylmethacrylate (PMMA) bone cement is a popular bone void filler for vertebroplasty. However, the use of PMMA has some drawbacks, including the material's excessive stiffness, exothermic polymerization, and short handling time. This study aimed to create an ideal modified bone cement to solve the above-mentioned problems. Modified bone cements were prepared by combining PMMA with three d...

The culture of synovial cells in vitro provides a useful means for the study of connective tissue function. Vaubel (1933) first used cultures of synovium to show that mucin was secreted in the joint itself, a conclusion since confirmed by others (Kling, Levine, and Wise, 1955; Castor, 1957; Hedberg and Moritz, 1958; Fischer and Torgerson, 1960). In recent years, Castor has studied synovial cult...

Novel reactive polyols were synthesized via modification of castor oil, a renewable agricultural raw material with epoxy resin and triethylamine as a catalyst. This polyol was used for synthesis of polyurethane coating. Coating formulations were developed by reacting polyol with aromatic adduct, aliphatic adduct and castor oil based adduct in different NCO/OH ratio. All coating composition syst...

Slices of 25- to 28-day-old developing castor bean endosperm were incubated with various (14)C- and (3)H-labeled substrates to determine the amount of glucose dissimilated in the pentose phosphate pathway and to determine the use of the reduced nucleotides so produced in fatty acid synthesis. Ten to 12% of the metabolized glucose traversed the pentose phosphate pathway, and reduced nicotinamide...

BACKGROUND The allergenicity of Ricinus communis L. (castor bean, Euphorbiaceae) is associated with components of its seeds and pollen. Castor bean allergy has been described not only in laboratory workers, but also in personnel working in oil processing mills, fertilizer retail, the upholstery industry and other industrial fields. In the present study, we describe the critical amino acids in t...

This study was aimed to provide the pharmacological basis for the medicinal use of Lepidium sativum in diarrhea using in vivo and in vitro assays. The seed extract of Lepidium sativum (Ls.Cr) at 100 and 300 mg/kg inhibited castor oil-induced diarrhea in rats. In isolated rat ileum, Ls.Cr (0.01-5 mg/mL) reversed carbachol (CCh, 1 µM) and K(+) (80 mM)-induced contractions with higher potency agai...
