Diffuse idiopathic skeletal hyperostosis (DISH) is a relatively common disorder predominating in men (65 to 70 percent),i with a prevalence of approximately 3 percent in adults older than 40 years of age2 and from 12 percent to 15 percent in patients more than 65 years of age.3,4 In 1950 Forestier and Rotes-Querol5 introduced the term senile ankylosing hyperostosis of the spine. DISH has long b...

We have examined the effects of various mannans, glycoproteins, oligosaccharides, monosaccharides, and sugar phosphates on the binding and phagocytosis of yeast cell walls (zymosan) by mouse peritoneal macrophages. A phosphonomannan (PO(4):mannose ratio = 1:8:6) from kloeckera brevis was the most potent inhibitor tested; it inhibited binding and phagocytosis by 50 percent at concentrations of a...

This paper investigates the persistence of poverty over individuals' lifetimes using a hazard rate approach that accounts for multiple spells of poverty and incorporates spell duration, individual and household characteristics, and unobserved heterogeneity. The findings highlight the importance of considering multiple spells in an analysis of poverty persistence, with half of those who end pove...

An improved design of the buffalo gun, incorporating hole drilling and shooting into one operation with almost total blast containment, provided nearly 50 percent more recordable seismic signal than the traditional buffalo gun. The ‘auger gun’ is designed to optimize field efficiency, source couple, and safety. The auger gun consists of three main parts: power source, auger/screw, and modified ...

The dissociation constants of the following substituted phenols in 50 wt percent methanol have been measured at 25 °C: o-nitrophenol, p-nitrophenol, 4-methyl-2-nitrophenol, 2,6-di chlorophenol , pentachlorophenol. The respective values found, expressed as pK values, are 7.91" 7.692 , 8.28" 7.680 , and 5.27.. The dissociation cons tants of 4-methyl-2-nitrophenol and pentachlorophenol, again exp ...

Metallothionein from livers of mice was isolated by gel chromatography and isoelectric focusing. One of two forms thus obtained contained 32 percent cysteine. This form, labeled in vitro with 109Cd, was injected intravenously in mice, and the distribution of 109Cd was studied. Animals killed after 4 hrs had over 80 percent of the injected dose in the kidneys. Protein obtained after gel chromato...
