A 34 amino acid hen egg-white lysozyme (HEL) peptide was designed and synthesized to investigate if an immunogenic peptide once bound to an Ia molecule becomes proteolytically inaccessible. The determinant recognized by T cells, HEL(52-61) was composed of L-amino acids whereas the 12 amino acid extension on each side of this core were composed of D-epimers. This peptide, HEL(40-73) was resistan...

Noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonists can produce positive and negative symptomatology as well as impairment of cognitive function that closely resemble those present in schizophrenia. In rats, these drugs induce a behavioral syndrome (characterized by hyperlocomotion and stereotypies), an enhanced glutamatergic transmission in the medial prefrontal cortex, and damage ...

The definition of comparing two pointers for equality is found in 5.10 ¶1: Pointers to objects or functions of the same type (after pointer conversions) can be compared for equality. Two pointers of the same type compare equal if and only if they are both null, both point to the same object or function, or both point one past the end of the same array. What does it mean for two pointers to " po...

The present paper attempts to quantify the diffusion of Newcomen engines in the British economy prior to the commercial application of the first Watt engine. It begins by pointing out omissions and discrepancies between the original Kanefsky database and the secondary literature leading to a number of revisions of the former. The diffusion path is subsequently drawn in terms of adopted horsepow...

The Effect One hundred years ago, the Gestalt psychologist Max Wertheimer published the first detailed study of the apparent visual movement seen when two adjacent lights are flashed sequentially (see Kolers, 1972). Apparent movement can be created by presenting any two identical pictures successively, with the second shifted slightly in position relative to the first. Figure 73-1a shows a very...

light petroleum or carbon tetrachloride, but was extracted into butanol, in which the colour was stable for several days. The product of bufotenin oxidation remained in the aqueous phase with all the above-mentioned solvents including butanol. When a concentrated solution of serotonin was oxidized by concentrated denaturing oxyhaemoglobin, the filtrate was a turbid brownish pink which formed a ...

BACKGROUND Several systemic factors and hormones are thought to regulate the fracture healing process. Vitamin D has emerged as a compound or hormone that actively participates in the regulation of calcium homeostasis and bone metabolism. OBJECTIVES The aim of this study is to determine the serum changes in the level of vitamin D during the acute healing period of tibial and femoral shaft fra...
