Treatment of chicken blood smears and semithin sections from Epon-embedded mouse tissues with aqueous solutions of the 3-aminonaphthalimides FA-142, FA-2043, and FA-2143 induced a strong green-yellow fluorescence of chromatin under violet or violet-blue excitation. Chromatin emission was abolished by previous DNase or hot TCA treatment. The use of 3-methoxy (FA-655) and 3-nitro derivatives (M-4...
The rational design of inhibitors of human renin for the treatment of hypertension depends on a detailed knowledge of the renin-angiotensinogen transition-state complex. Direct determination of the three-dimensional structure of complexes of human renin with transition state analogues is not possible until large quantities of human renin are made available by recombinant DNA techniques. Neverth...
GEO is a well-differentiated colon cancer cell line that coexpresses the epidermal growth factor-like growth factors CRIPTO (CR), amphiregulin (AR), and transforming growth factor alpha (TGF-alpha). Antisense 20-mer phosphorothioate oligodeoxynucleotides (AS S-oligos) directed against CR, AR, and TGF-alpha mRNAs were equipotent in their ability to inhibit both the anchorage-dependent growth and...
Introduction: Nowadays, Shielded Metal Arc Welding (SMAW) is the most widely used arc welding. During the welding operation, typically, various harmful agents such as fumes, gases, heat, sound and ultraviolet radiation are produced of which fume is the most important component from the viewpoint of occupational health. The present study aims to compare the number and the mass concentration emit...
Cartilage stiffness was measured ex vivo at the micrometer and nanometer scales to explore structure-mechanical property relationships at smaller scales than has been done previously. A method was developed to measure the dynamic elastic modulus, |E(*)|, in compression by indentation-type atomic force microscopy (IT AFM). Spherical indenter tips (radius = approximately 2.5 microm) and sharp pyr...
