let $g$ be an $(n,m)$-graph. we say that $g$ has property $(ast)$if for every pair of its adjacent vertices $x$ and $y$, thereexists a vertex $z$, such that $z$ is not adjacentto either $x$ or $y$. if the graph $g$ has property $(ast)$, thenits complement $overline g$ is connected, has diameter 2, and itswiener index is equal to $binom{n}{2}+m$, i.e., the wiener indexis insensitive of any other...

angioedema is characterized by recurrent, circumscribed, solitary or multiple subcutaneous and mucosal swelling, involving the extremities, face, larynx, bowel wall. angioedema is due to hereditary or acquired varieties of c1 esterase inhibitor (c1inh) deficiency. a case of atypical acquired angioedema in a 49-year old man, responding favourably to cinnarizine and alcohol abstinence, is present...

background: the serum levels of c 3 , c4, and the total hemolytic activity of complement system (ch50) of patients ex­posed to mustard gas (mg) in the battlefield were measured in this study. methods: c3 and c4 were measured by single radial immunodifusion and ch50 was evaluated according to total hemolytic activ­ity of the serum. results:   the serum levels of c 3 showed a significant increase...

to reduce stimulation to a minimum or to achieve "optimal" states of stimulation. The author's contention is that there is a drive for optimal levels of stimulation that leads organisms to avoid states where sensory variation is either too high or too low. This "sensoristatic drive" is a state of cortical arousal that is monitored by the reticular formation which serves as a regulator adjusting...
